| Communicate with customer three-way machine
Today, I inquired and communicated with the Indian customer who makes tee pipe fittings on Facebook. He was interested in our company's cold extrusion tee machine series, and learned about our company's other elbow machine, IF pipe expanding machine and other pipe fitting equipment.
Three-way forming machine is also called "three-way forming machine". The utility model relates to the field of hydraulic forming equipment of pipe fitting industry, and is a small and large size three-way pipe hydraulic water expansion forming machine.
Pipe internal high pressure forming technology usually uses pipe billet as raw material, by applying high pressure liquid pressure to the tube billet cavity, axial load is applied to make it plastic deformation in a given mold cavity, pipe wall and mold surface fit, so as to get the required shape parts technology. It is suitable for extrusion molding of stainless steel, copper and aluminum three-way pipes. It is characterized by a pair of transverse synchronous cylinders and a symmetric mandrel on the axis of the cylinder. And can realize automatic production.
Three-way pipe fitting is a kind of common pipe coupling with large consumption and wide area in modern industry. Local eddy current will appear in the process of conveying medium and high pressure liquid or gas, which has a great influence on the performance of pipe fitting. In the past, there were many serious shortcomings in the production of tee pipe fittings by traditional manufacturing methods, so now the excellent seamless steel pipe is used to form tee pipe.
Internal high pressure process and flanging process to produce seamless tee fittings. For internal high pressure technology, using DYNAFORM software to simulate first, analyzed the technology parameters (internal pressure, axial and radial feed force back pressure) of loading paths on the influence of three-way tube high pressure forming, through the engineer found that: (1) enough feeding is necessary conditions to obtain a certain height of branch pipe, but feeding is too large, will cause the wall thickness of yan Weight increase; (2) The influence of internal pressure and back pressure is opposite. Too much internal pressure or too little back pressure will cause excessive thinning or even rupture of the top of the branch pipe. On the contrary, the height of the branch pipe is too small.
By predicting and optimizing the matching relationship of high pressure process parameters in different sizes of tees, better quality tees can be formed. Existing enterprises to produce large diameter three-way pipe through multiple flanging process, called multistage flanging process. The pipe fitting mechanical series of cold extrusion three-way machine has high production efficiency. The shape of the three-way pipe fitting produced is beautiful and the quality standard is mostly up to the standard.
Looking forward to cooperating with this customer in our company. We will continue to talk to them.
