| The four characteristics of pipe bending machine and Angle introduction
The process of the pipe bending machine can prevent the asymmetry of pipe wall thickness caused by the tension thinning of the convex edge of the pipe wall and the compression thickening of the concave edge of the pipe wall when the traditional pipe bending process is forming.
Accepting this process, 180 elbow with small radius (R≈D) and thin wall (t/D≈0.015) with well-proportioned wall thickness can be produced, which cannot be achieved by other bending processes.
If the process parameters are planned fairly, the process can ensure that the wall thickness of each part of the pipe bending process is always connected and stable, that is, the wall thickness of straight pipe blank before deformation.
With this technology, bend pipes with similar diameters of 45, 90, 180 and other bending angles can be produced at the same horn mandrel at the same time.
Medium frequency pipe bending machine is to accept the medium frequency electric heating, the workpiece in the local heating under the condition of bending. Compared with the general cold pipe bending machine, it also needs a complete set of common molds, and the machine volume only accounts for 1/3 ~ 1/2 of the cold pipe bending machine of the same specification. Medium frequency hot pipe bending technology is an economical and useful one among all kinds of existing pipe bending technology.
The process of intermediate frequency bending pipe is to put a ring on the steel pipe to be bent, stick the tube head with a mechanical boom, and heat the steel pipe with intermediate frequency current in the ring. When the temperature of the steel pipe rises to a plastic state, the steel pipe is propelled by mechanical thrust at the back end of the steel pipe, and the bending steel pipe is quickly cooled with coolant, so that heating, pushing, bending and cooling are allowed. Keep bending the pipe out. Intermediate frequency bend pipe is widely used in the pipeline prefabrication of electric power, petroleum, chemical industry, sailing, nuclear industry and other engineering fields, but the wave fold of intermediate frequency bend pipe at the arc is obviously larger, especially when the bending radius is less than 3Do (Do is the outer diameter of the pipe), the inner arc wave fold is larger, which seriously affects the appearance quality of the product. This is decades of domestic pipe bending machine can not solve the problem urgently.
Knowledge of our equipment: Pipe bending machine can be divided into hydraulic pipe bending machine, medium frequency pipe bending machine, etc., mainly used in electric power construction, highway, construction, boiler, bridge, furniture and other aspects of pipeline laying and repair, with many effects, reasonable structure, simple operation and other advantages, hydraulic pipe bending machine has the effect of pipe bending, but also can use the cylinder as a jack, relative to hydraulic pipe bending machine equipment has a reasonable cost, Easy to use, in the domestic pipe bending machine market dominant equipment.
Operation process of pipe bending machine: can make a variety of different caliber and wall thickness of steel pipe, can bend a variety of angles and arcs, compound bending and more than 180 degrees of arc, too large arc is not only used in construction, and by the size of the pipe bending machine, arbitrary curve, bending machine in the operation of our company can make automatic feeding and production efficiency according to customer requirements.
Mainly used for electric power construction, railway construction, boiler, bridge, ship, furniture, decoration and other aspects of pipeline laying and repair, with many effects, reasonable structure, simple operation and other advantages. In addition to the effect of pipe bending, the machine can also use the cylinder as a hydraulic jack. Compared with CNC pipe bending equipment, it has the characteristics of self-made cost, convenient use, and occupies a leading position in the domestic pipe bending machine market.
The operation mode of pipe bending equipment: First, before the operation of pipe bending machine, our company staff need to read the operation instruction. Screw the cylinder into the thread of the square stop block so that the rear end of the cylinder is mounted on the rack of the wheel downward. Select the measuring head according to the outside diameter of the pipe bender, put it on the plunger, put the corresponding slots of the two rollers toward the measuring head, and then put it into the flower plate hole of the corresponding size. On the cover of the upper flower plate, insert the bent pipe into the groove, pull back the quick discussion section of the high pressure oil pipe end and put it on the discussion of the oil cylinder, tighten the oil discharge screw of the electric oil pump, and then bend the pipe. After bending the pipe, loosen the oil drain screw and the plunger will reset automatically.
Pipe bending machine can be divided into CNC pipe bending machine, hydraulic pipe bending machine and so on. Mainly used for electric power construction, railway construction, boiler, bridge, ship, furniture, decoration and other aspects of pipeline laying and repair, with many effects, reasonable structure, simple operation and other advantages. In addition to having the effect of pipe bending, the machine can also use the cylinder as a hydraulic jack. Compared with CNC pipe bending equipment, it has the characteristics of self-made cost and convenient use, and occupies the leading product position in the domestic pipe bending machine market.
Pipe bender is a kind of industrial equipment. Pipe bending machine can be divided into CNC pipe bending machine, hydraulic pipe bending machine, etc. Mainly used for electric power construction, railway construction, boiler, bridge, ship, furniture, decoration and other aspects of pipeline laying and repair, with many effects, reasonable structure, simple operation and other advantages. Application of pipe bending machine: it can bend all kinds of plane pipe and space pipe which can be delimit. After replacing the mold, it can bend all kinds of round steel, Angle steel, channel steel, flat iron and other profiles.
The use of hydraulic pipe bender essentials: the switch clockwise deflection tighten, loosen the bolts on the refueling port. The bending mould, the supporting wheel and the parts of the bending pipe are smooth and greasy. Then insert two bearing wheels into the lower formwork and two corresponding holes and place them on the bent pipe. Rotate the two supporting wheels to turn the upper formwork towards the bent pipe. First, use a large plunger pump and bump the handle to make the bent pipe press into the bent pipe. Then the small plunger pump is pressed to the desired Angle. After bending, loosen the switch anticlockwise, the action will automatically reset, uncover the upper template, pull out the pipe.
