An Important Processing Method for Stainless Steel Equal Tee

Stainless steel equal tee extrusion processing is a kind of pressure processing. Stainless steel tee squeeze the essence of the theory is the application of external force, so that in the extrusion tube in the stainless steel tube by three-dimensional compressive stress and plastic deformation, squeeze through the extrusion die from the gap, so get a certain Cross-sectional shape and cross-sectional size of the product pressure forming process. Extrusion processing is suitable for the production of stainless steel tee and its alloy products, and its application is extremely extensive, especially in the fields of communication, construction, transportation, aviation and so on.Therefore, the extrusion process is in the field of stainless steel occupies a very important position. Because the extruded stainless steel tee is in a three-phase stress state, it is possible to obtain a greater plastic deformation than rolling and forging. Since the development of self-extrusion technology, there have been new technology, new equipment, new workers, so that extrusion processing technology has developed by leaps and bounds.

Extrusion is a variety of stainless steel tee and its alloy production and parts forming one of the main methods, is efficient, high quality, low consumption of small, no chip processing technology. Stainless steel tee under the three-way compressive stress plastic forming, the formation of fewer defects, comprehensive performance, high value-added.

Extrusion cylinder is an important part of the extrusion equipment, the design of a reasonable extrusion cylinder, can reduce the force of the extrusion cylinder, improve service life, increase the capacity. The use of multi-layer combination of extrusion cylinder, when the lining damage occurs, just replace the lining, which not only reduces the loss of stainless steel tee reduced costs, but also extended the life of the extrusion cylinder. In addition, the stainless steel pipe plant to select the appropriate size and processing technology is also the main way to improve its life.

In order to reduce the overall force of the extruder cylinder, the stress distribution inside the extruding cylinder is improved, and the service life of the extruding cylinder is improved and the service life is increased. At present, most extruding cylinders adopt two or three layers Extrusion cylinders are assembled together with an interference fit so that the inner liner can be replaced only after the lining has been worn and deformed, thereby reducing the material consumption of the extrusion cylinder. The design method is to first design a good amount of interference processing and processing of the layers of the bushing, and then the second layer of the sleeve heated to a certain temperature to expand, and finally the inner liner into the second layer of the sleeve. When cooled, the second layer of bushing shrinks to produce a certain preload stress on the first layer of bushing and is combined with the first set to become a whole. In the same way, the third layer of the sleeve heated to a certain temperature, and then the first and second layer of the composition of the "whole" into the third layer of the sleeve, so that the three-tier sleeve on a combination of a whole, It formed a multi-layer modular extrusion cylinder.
