| The whole process of a push-making machine producing elbow
Push machine you may have seen, if you do not see can choose to look at the push machine in the website, push machine operation is very simple, it is a mandrel or horn, mandrel has fine coarser, push process is a process of expanding with bending.There is a support behind the cutting pipe end into the mandrel, behind a memorial arch frame will be fixed mandrel.There is a car in the middle, some of the car through hydraulic transmission, some through mechanical transmission that is, screw transmission, and then push forward the car.The trolley pushes the pipe along the mandre to go forward, and there is an induction ring outside the mandre. Heate the pipe, and then the trolley pushes the pipe down, and then one is processed. After pushing, the elbow should be reshaped in this hot state.Because some elbow improper handling, will be twisted, this is not allowed.In addition, after pushing the head is generally large front diameter, to be reshaped through the shaping mold.Plastic mold is actually a press, to have a set of molds, two semicircular arcs, up and down one.After the shaping of the outer diameter to reach the size of the finished product requirements.The wall thickness is controlled by the wall thickness of incoming material.Elbow and pipe wall thickness tolerance is the same, all is 12.5%, in the process of driving system, under normal circumstances wall thickness should not be changed, but if for tool reason, some local wall reduction happens, so generally refer to material, wall thickness to add some allowance, if the elbow is 8.18 mm wall thickness, pipe of the 8.5 mm or so commonly,Prevent out of tolerance due to local thickness reduction when pushing.After setting the shape, the outer diameter and wall thickness of the elbow are hit the requirements, and the following finishing process is carried out. After sandblasting, the oxide iron sheet on the inner and outer surface of the elbow is removed, and the bevels at both ends are processed so as to facilitate welding.After inspection, typing, painting, packaging and other processes, can be factory.
Classification of elbow machine
There are many kinds of elbow machine classification: medium frequency elbow machine, cold push elbow machine, Xiami elbow machine and spiral elbow machine, the company mainly produces medium frequency elbow machine and cold push elbow machine.
Medium frequency elbow machine main raw material is carbon steel, alloy steel.
Cold push elbow machine mainly produces stainless steel.
Intermediate frequency elbow machine mainly includes: alloy core head, intermediate frequency coil bracket, intermediate frequency coil, export bracket, auxiliary rod, push plate door, hydraulic door cylinder, push plate, back gate, hydraulic lifting cylinder, main cylinder, cylinder back bracket, feeding core rod, large chassis, main core rod, motor, steering piston pump, integrated block and so on.
Medium frequency elbow machine time color elbow special equipment, can produce 21-1620mm, wall thickness of 3-100mm, multiple is more than 1D carbon steel, alloy steel elbow.Welcome new and old customers to visit and call.
