| The welding elbow forming process is formed by pushing machine
Welding elbow hot forming process is the use of special welding machine, core die and heating device, so that the blank set on the mold in the push machine to move forward, in the movement of heating, expanding and bending forming process.
Hot push bend deformation characteristics is determined according to the law of metal plastic deformation volume before and after the same pipe diameter, the tube billet diameter used less than bend diameter, through the core module and control the deformation of the process, make the inner arc compressed metal flow, the compensation to other parts of the thinned by expanding, resulting in wall thickness of the elbow.
Hot bend forming technology has good appearance, uniform wall thickness and continuous operation, and suitable for the characteristics of mass production, and thus be carbon steel, alloy steel elbow main forming method, and also used in some of the specifications of the bend forming, the forming process of heating have intermediate frequency or high frequency induction heating, heating and reverberatory furnace flame heating,What kind of heating method is used to shape the product requirements and energy conditions.
The specific function and implementation process of each part of the push machine
The back bracket and support plate of the push machine mainly play the role of supporting the oil cylinder, and ensure that the horizontal position and vertical position of the oil cylinder are accurate.
Push machine in the process of work, the cylinder forward to push the push plate forward, push the plate in front of the production pipe is also forward.Push plate in the chassis track rolling forward, both sides are equipped with auxiliary rod guide, can determine the accuracy of the product.The front end of the pipe is mounted on the inlet bracket to ensure that the center line of the pipe is in a horizontal position and the direction of the pipe is accurately guided.
