| The processing process of medium frequency elbow machine
The components of the intermediate frequency elbow machine include the main engine, hydraulic pump station, operation table, motor control cabinet, intermediate frequency power supply, compensation capacitor, water cable, intermediate frequency coil adjustment frame, reactor.
Machine will be hot is expected to push, push system is a head or a horn core mandrel, mandrel from fine to coarse, elbow bend machine automatically push system process is a process with a curved hole diameter, the back support, under the section through the mandrel, a memorial arch frame behind the mandrel is fixed, there is a car, the car some through hydraulic transmission, some mechanical transmission by lead screw transmission, Then push the car forward, the car pushes the pipe along the mandrel, the mandrel has an induction ring, the pipe is heated, heated well, and then the car pushes the pipe down, and an elbow is processed.
In the hardcover process, after shot peening treatment, the oxide scale on the inside and outside surface of the elbow is removed, and the two ends are beveled to facilitate welding.
Before the medium frequency elbow machine pushes the elbow, the specification should be selected. The pipe material, such as a 90 degree elbow, can be calculated through its curvature to determine how long the material can be processed into a 90 degree elbow, and then cut off with the length as a fixed ruler
Push, bend it so hot condition to correct, because some elbow after improper handling will be distorted, this is not standard non-standard products, in addition push the good elbow are generally large front end diameter, to pass the correct mode to correct, correction model is press actually, want to have a set of mould, two and a half arc, each one from top to bottom, from outside diameter is reached after the size of the finished product.
