| Working principle of intermediate frequency elbow mechanism for elbow
Intermediate frequency elbow mechanism for elbow principle: this elbow machine mainly through local alloy core head heating (electromagnetic induction principle) deformation into the shape of the elbow;
Making elbow process: (1) by the push pipe machine will have been cut and set on the steel pipe and alloy core head slowly pushed to the alloy core head heating part of the steel pipe heating part is supported to the shape of the elbow to the division of the fall off;(3) move to the mold has been done for correction;
The main components of the machine: ① alloy core head ② intermediate frequency coil and its support ③ outlet support ④ push pipe device ⑤ cylinder ⑥ motor and other parts;
Scope of application: ① nozzle diameter range: 21mm -- 1620mm ② wall thickness range: 3mm -- 100mm③ bending radius: 1D -- 1.5D -- 3D;
Advantages and disadvantages:
Advantages: fast speed, automation, no damage to the steel internal structure, elbow material selection range is wide, save manpower;
Disadvantages: the selection of elbow material is mostly suitable for the alloy that can produce electromagnetic induction, such as: can not make stainless steel elbow, in the process of making the elbow also need to brush lubricant on the inner wall of the steel pipe, otherwise easy to appear other problems.
The structure and working principle of the push machine
Pushing machine equipment for double cylinder or four cylinder average speed forward, pump station valve platform adopts integrated form.The pumping station is composed of multiple stages. There are 2-3 working pumps for the equipment of the first to the sixth specifications, and 1 working pump station for the bending test equipment of the seventh and eighth specifications. One book and one historical background is set.
Pushing machine is divided into one push push bending in two and three push push two forms, hydraulic two push bending machine, the total stroke of standard type can be customized according to the requirements of users directly.
Pushing machine material by the feeding machine, driving steel wire rope, push pipe, steel wire rope wheel, to work, the original pipe to be expanded into the equipment.
The intermediate frequency power supply is installed in the front of the equipment, and the intermediate frequency induction coil is secured on the adjustment frame. The expanding tube core head mold is installed, and the power supply is turned on to push the system.
The advantages of the push machine are: powerful power, stepless speed, simple operation, safe and reliable, forming products of higher accuracy.
