Elbow manufacturers on the production of elbow pip

Elbow manufacturers on the production of elbow pipe fittings process introduction

Hot push elbow forming process is the use of commonly used elbow pushing machine, core die and heating device, is set on the die billet in the push machine under the push forward movement, in the movement of heating, expanding and bending forming process.Hot push bend deformation characteristics are based on metal = the law of the material in front of the plastic deformation volume determine the pipe diameter, diameter of tube billet adopted by the bosom friend is less than the elbow, through 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 hole diameter, wall thickness uniform Angle is obtained.Hot bend forming technology has good appearance, uniform wall thickness and continuous operation, and suitable for the characteristics of mass production, and thus become carbon steel elbow, alloy steel elbow, the forming process of the main application and also in some of the specifications of the stainless steel elbow forming, the heating mode in the process of forming a medium frequency or high frequency induction heating, heating and reverberatory furnace flame heating, adopt what kind of heating forming product requirements and the energy situation decision.

Stamping forming elbow is the forming process of mass production of seamless elbow which is used at the beginning of the production of elbow fittings above. At present, it has been replaced by hot pushing or other forming processes in the production of commonly used specifications of elbow, but in some specifications of elbow, the wall thickness is too thick or too thin due to the small production quantity.Still in use when products have special requirements, the stamping elbow is used to outer diameter of the bend tube billet, equal use press press forming directly in the mould, before stamping of the tube billet is put on a mold, the mold filling and end into tube billet, the downward movement of upper die began to suppress, supported by outer and inner mold the constraints of the bend forming.

Hot push bend forming technology is to use common elbow push system machine, core mold and heating device, to set on the mould of billet in pushing forward movement, under the impetus of the machine is heated in the exercise, hole diameter and the process of forming, the deformation characteristics of the hot pushing elbow is according to the volume before and after plastic deformation rule of metal materials determine the pipe diameter, the tube billet diameter used less than bend diameter, through the core module and control the deformation of the process, is the internal arc compressed metal flow, the compensation to which parts of the thinned by expanding, resulting in wall thickness of the elbow.

Hot push elbow forming process has the function of beautiful appearance, uniform wall thickness and continuous production, and is suitable for mass production, so it has become the main production process of carbon steel and alloy steel elbow.
