| Explanation of intermediate frequency elbow machine
Intermediate frequency bend machine in the production of seamless elbow forming process including the cutting the tube billet into core mold, with dedicated push the machine for continuous heating, hole diameter, forming process, such as hot push bend forming process with uniform wall thickness, good appearance and characteristics of sustainable production, has become the world numerous fittings factory in the production of carbon steel, alloy steel seamless elbow preferred process.
In addition to the inherent factors of raw seamless steel pipe itself, the factors affecting the forming quality of elbow press elbow are mainly related to the geometrical shape of the core die, heating temperature and the diameter of pipe billet.The elbow is a widely used pipe fitting in the device or process pipeline of many industries such as petroleum, chemical industry, power station, shipbuilding, etc. Its reliability is of great significance to the safe operation of the whole device.
Hebei elbow machine manufacturers explain the action process of elbow machine
The elbow machine equipment mainly includes: the frame, the main cylinder support plate (including the main cylinder), the movable push plate, the front support plate, the semi-automatic feeding mechanism, the intermediate frequency coil adjustment frame (including the intermediate frequency heating coil), the intermediate frequency power supply, the electrical control system and so on.
Intermediate frequency bend motor as a process: the two pieces of blank tilt into the mould at the same time, the use of lower die before and after the location and the steps of the central, the lower die side lateral positioning of positioning plate, using the upper and lower die wall to short side bending, such a work schedule in the press, bending forming a workpiece two direction, do not need to pressure device.This structure can not only two workpiece at a time, and at the edge of the curved short when the lateral force can be offset each other, to avoid the adverse impact of the lateral force and tilted at the same time two blank of upper die and automatic guiding role, because the workpiece material is stainless steel, the bending springback tendency is bigger, so consider the measures to reduce springback when mould design, particular way is:Convex and concave die single clearance is equal to 4-4.4mm, and the forming die has 1° rebound, the workpiece is pressed by friction press, press slide down and contact with two workpiece, down to the lowest point, the workpiece bending deformation, and with enough correction force, to ensure the bending accuracy of the workpiece.
