CNC flame cutting machine cutting plate inclination operating skills

 CNC flame cutting machine cutting plate inclination operating skills
More than 25mm thick metal cutting CNC flame cutting machines in operation, its cutting quality results compared to plasma cutting has obvious advantages, the main

Manifested in the vertical plane and slotted finish, the other using CNC flame cutting machine can provide for the needs of cutting angle, when the use of flame cutting torch high

Degree of control, the teflon hose size of the air pressure, cutting speed and cutting thickness is an important factor to consider. Here CNC flame cutting machine torch inclination to be a simple set

Analysis:

According CNC flame cutting machine automatic cutting and semi-automatic cutting different ways to adjust the distance between each of the torch, determined the amount of drag, and consider cutting compensation; after cutting

Cutting process, the size of the torch angle and direction of the thickness of the steel plate mainly when cutting thick cut pieces of <10mm when needed torch inclination backward 10 ° -15 ° to make the cut

Cut to achieve the best; otherwise you will need to torch perpendicular to the plate surface. Also in terms of quantity kerf width is required to remain entirely based on cutting thickness from the line settings, where

We take the two kinds of thickness to a brief description of the relationship between the two, for the <10mm thick plate cutting kerf compensation generally set to 1mm down; 40mm or more in the timber

Material, cutting kerf compensation setting is generally about 3mm.

CNC flame cutting machines during automatic cutting, hanging steel to cutting platform, should be adjusted unilaterally steel rails across the head and distance difference of 5mm range. In

Semi-automatic cutting, should be cut steel rails placed on the plane, and then cutting machine lightly on the rail. So there is the side facing the torch operator, according to the

Selection of cutting nozzle plate thickness, adjusting cutting straightness and cutting speed.

It should be noted that, before we are talking about are based CNC flame cutting machine processing as the basis for the use of plasma cutting and processing enterprises, achieving angle cut

Cutting process is the socketless fitting establishment of any course, the key lies in matching plasma cutting power source output can be achieved in the process of cutting angle, wear plate thickness changes, such as a

Taiwan LGK-100A plasma power, cutting 8mm thick material, the inclination angle of the cut is relatively limited; while for 10mm thickness of the material is completely impossible dumping

Angle cutting, which is also requested user's attention.

how to reduce fabric hose diameter round loss

Fabric hose because no molding vulcanized rubber hose inside diameter round loss is inevitable, may take the following measures to reduce the degree of loss round:

① rational design of inner plastic recipe, use less liquid softener, and the use of solid softener such as asphalt, resins and other solid Coumarone the tube well connected, easily deformed under pressure;

② inner plastic thickness cost permitting appropriate to increase (to be appropriate to reduce the cost of compensation with gum);

③ outer plastic extruded hose should be closely sulfide emissions and as soon as possible;

④ using direct steam curing, pipe clamp the inner diameter of 25mm hose the following vulcanization tray stacked layers not more than 3 layers stacked inside diameter of 32mm hose should not be more than two layers, inner diameter 38mm above the hose out of round seriously, best not to use this curing process, Boiled vulcanized be limited though, but should be avoided for the production of large diameter hose. Some factories had large diameter hose (32-76mm) conducted coreless direct steam partial pressure vulcanization molding experiments, the solution was bubbled delamination problems and the inner diameter round loss to obtain better results.

Fabric hose diameter round loss solution is: The ends can be uncapped autoclave, the tank in addition to a normal inlet pipes and exhaust pipes, the ends of the tank into the creation of flexible connections steam pipe and exhaust pipe, forming a good hose is placed on the platen vulcanizing car, there are loose ends platen steam through multi-plug pipe fittings, hose ends are inserted into each respective plug inside, fixed with clamps Well, then vulcanized vehicle selected into the tank, respectively, connected multi-plug Explorer and soft steam pipe attached securely closed autoclave, start with one end of the flexible hose connected to the steam pipe to metric banjo fitting enter the steam, and then give it away again autoclave steam, pressure inside the hose high pressure over 0.02 a O.03MPa tank under vulcanization. Hose inside the tank and the need for timely condensate discharge. After curing, while maintaining pressure exhaust steam and spray cold water in the tank to cool cans of soft connecting tube after each unload, pull vulcanized car relieved fixture, remove the hose cutting head checked.

hydraulic components superimposed Technical Analysis

Stacking manifold ways with a variety of specially designed plate connected to valve according to the ordinary requirements of the system stacked up in the hydraulic system integration methods, collectively known as HMB superimposed integration technology. Integrating in this way a hydraulic system, can be seen, modular valves, valve plate hydraulic hose adapters connections and connection blocks. Superimposed valve in the hydraulic circuit block shape its structure, named after the name suggests it is a stacked each other hydraulic valves, is to adapt to this integrated approach and special design. Rather, the overlay is superimposed valve connected hydraulic valves. It is connected to the hydraulic valve plate developed on the basis of integration of new hydraulic components. Which itself contains from 1 to 2 separate valves, its internal structure and general hydraulic valve similar. The valve between the upper and lower surfaces of the joint surface, the valve surface in both imports and exports. In addition, there is for internal connection hydraulic couplings between the valve channels. Therefore, modular valves in the hydraulic valve play both the role of connecting passage between the valve underway role.

hydraulic hose reinforcing material, which has several

 Hydraulic hose fittings, currently used and is studying the skeleton data to develop inclusive of cotton, nylon, high-strength steel wire, flax, linen, polyester, glass fibers, asbestos and carbon fiber, rayon and polypropylene, convention, from Select strengthen these categories data, as a decisive factor in voltage grade.

        When dealing with those more special fabrics such as polyester and polypropylene, it is necessary very careful to assure precise heat setting level, or when the onset of vulcanized rubber hose should not have deformed.

        In the use of polypropylene, it is necessary to think about curing temperature carefully. Degrees premise, since in many places, this temperature is very close to the softening point of the substrate. When using this type of yarn or fabric, special adhesive system is also required in order to guarantee the hose and components with plenty of well-organized and the Heart of the bonding results.

        Glass fibers and asbestos hose nipples fibers have been used for steam hose and other heat-resistant hose. Of course, the wire is also used for such use.

        The presentation of a new carbon fiber gum gum category can be used, but the current cost of this new information is high. Therefore, in addition to over the coming years in the space outside the scope does not extend to use; and carbon fiber on which points are worth noting: For tensile strength as compared to the carbon fiber reinforced fiberglass difference information with little or no two who has a high tensile and low density values ​​- equivalent to 25% of steel, however. great benefit of the use of carbon fibers reinforced with such media is high strength steel having a large data five or six times greater than the glass fiber characteristic modulo value, characterized in modulus can be used as a measure of tensile load, which can support the specific component of the beam and not flat clothes, thus. subsequent carbon fiber tends to be used for the reinforcement of metals and ceramics, and not as normal that the pure fiber data: it is Christ in the rubber industry can be very useful in the manufacture of fittings and hydraulic system dynamic sealing,

        Another high-strength, high cost fibers are chemically aromatic amine polyphenol family, a member of the demand is high strength, excellent heat and chemical resistance of places, with it specifically useful. The usefulness of the system include hose: Heavy launch machine (such as persistent heavy-duty engine and diesel engine vehicles convergence refrigeration and heat pipe) and subsea wells seawater for use on equipment-based high-pressure hose and so on.

65, mining machine fabric hose should pay attention to what?

From an opening, you use hydraulic bolt machinery and to improve their quality of life and a perfect mission effectiveness. Mainly hydraulic hose industry significantly affected, forever altered the appearance of human machinery. Hydraulic hose system, relying on high-pressure liquid power of money, cloth hose in order to implement its instinctive drive. This liquid purity is to shut the main form so that it can carry out its objectives, which means to go through the operation of petroleum distillation system hydraulic hose liquid filtration lost any impurities.

       In ancient times the motor cylinder and complicated varieties, will transfer cylinder and motor oil through the control valve hydraulic hose, hose, tubing. In our daily use for performing the main instinctive function, so a lot of mechanical hydraulic hose systems function in their use. Bulldozers, classified as reptiles, rigid plates move applications to participate in another set of each wheel, the use of the continuation of the track. Continue to track the activities of this goal is distributed over a larger surface of the wheel will be removed from pure mechanical quality. Bulldozer equipped with a dozer blade. "

       Bulldozer, even for a long time assigned to various types of machinery, accurate use of terminology to describe a dozer a persistent drive.

      This blade is the application of moving debris, sand and dirt, especially in the establishment of the task. In the first bulldozer, its blade brake, or a winch system moderation. They are currently equipped with a hydraulic cylinder, and promised a finer blade operation. Another exercise its function of hydraulic hose pieces are mechanical excavators. It is a commonly known as the excavation excavator stuff.

       Metal hose which in essence is a persistent machine, equipped with a hinged arm excavation program, the final one bucket. This is the closest to the vehicle's arm is called prosperity, another part is the arm scoop. Bucket and arm, accurate and highly complex activities thriving hydraulic hose momentum.

      Forklift hydraulic hose systems, and power supply. This mechanical lifting and transporting heavy goods, especially in mobile and landing pallet in the warehouse and distribution center inventory using industrial trucks. Forklift mast is progress and reduce the load performed most of the tasks.

hydraulic hose emergency repair of several methods

Hydraulic hose emergency repair of several methods
    During the construction process, construction machinery hydraulic system hose rupture, you can take the following emergency repair methods.
Stick reinforcing method
When the hydraulic system pressure at 25-8.0MPa rupture between the rubber hose can take when sticky patch method: Wipe clean around the hose rupture; painted in the hose rupture "anaerobic" glue, "Ring epoxy resin "glue," 801 "glue or" 502 "in one glue (glue a length of approximately 2-3 times the length of the rupture site); canvas with tape or glue strip overlying wound at 4 - 5 layers (each layer should be coated with glue); would draw canvas strip wound tape the ends tightly knotted; wait until solidification 15-20min after use.
Bundled France
Bundled law applies pressure 16MPa rubber hose rupture following emergency repair. The specific method is: the hose rupture coated gum foregoing construction machinery used in one; rupture site with a width of 2-3 times the length of the oil and rubber adhesive wound at 2-3 layers (each layer should be coated with glue ); No. 12 wire will be wrapped with good oil resistance rubber bundled good; let it solidify.
Bone France
As external forces reusable fitting (shrapnel puncture, crush fracture) or system overload causes large rubber hose rupture site or about to break, you can take the bone France: Wipe clean the hose rupture and cut rupture site; would homemade steel "bone" Insert the hose is cut off ("bone" parts as shown in the drawings, the situation is particularly urgent, they used the same outer diameter of the bone with the hose pipe when the "bone"); plates with homemade clamp the hose and the "bone" chuck (special emergency situations, the available alternative homemade No. 8 wire steel clamp); would take a good hose to clean after use.
Transposition
In the hydraulic system, the same oil rubber hose whose specifications the same, but different oil pressure to bear. Ruptured hydraulic hose mostly bear a larger hose. If W4-60 type excavator, ZL series loader boom cylinder on the two specifications of the same tubing is always connected to the boom cylinder large cavity hydraulic tubing to withstand greater. Accordingly, the method can be used to take transposition: A simple hose rupture sticky patch or bundled; big will the boom cylinder chamber and small chamber tubing can be used interchangeably (ie with unruptured tubing withstand high pressure, with the But after a simple supplement damaged or bundled tubing sticking to withstand low pressure).
Restructuring Act
As the hydraulic system of the rubber hose fittings vary, while high pressure or high pressure hose rupture should not be used "stick and fill method", "bundle Act" or "bone Law", which can be taken to reform law: Saw fitting the hose rupture; find a burst pressure capability, and the length of the hose the hose replacement approximate and saws its fittings; the fracture angle hose fittings welded to the replacement hose; the welding good hose cleaned immediately after use.
Opening Act
In the hydraulic system, valve block some of the oil plays a protective role in system security. Such as: W4-60 type excavator, ZL series loader steering system from the main oil passage through the relief valve to the tank; TY120 bulldozer working device in the hydraulic system relief valve, overload valves, relief valves, etc. oil. When these oil hose rupture in the circuit method can be taken; abandoned in the circuit protection device (such as a "safety valve", etc.); blocked oil hose leading to rupture, so that the oil circuit. In taking break law, should the system load control at rated load between 85% -95%.
