On-line Shot Peening And Cleaning Of Cold Extrusion Parts

  On-line shot peening and cleaning of cold extrusion parts

  Extruded parts are accurate and smooth

  At present, China's development of the cold extrusion of the general size of the accuracy of up to 8 to 9, the general degree of up to the length, if the ideal lubrication up to (referring to pure aluminum and copper parts), second only to fine polished surface. So the cold extrusion method to create the parts, generally do not need to re-processing, a small amount of only finishing (grinding).

  Cold extrusion material utilization rate can usually reach more than 80%. Such as Jiesuo brand car piston cutting processing material utilization rate of 43.3%, while the use of cold extrusion material utilization rate increased to 92%; and if the universal joint bearing sets to use cold extrusion, the material utilization rate from the past 27.8% to 64%. It can be seen that the use of cold extrusion method to produce mechanical parts, can save a lot of steel and non-ferrous metal materials.

  High productivity

  The efficiency of producing mechanical parts with cold extrusion is very high, especially in the production of bulk parts, extrusion parts with the use of cold extrusion methods to improve the processing of several times, several times, or even hundreds of times. For example, the car piston pin with cold extrusion method than cutting with manufacturing to improve 3.2 times, and now with cold extrusion piston pin automatic machine, so that productivity is further improved. The productivity of a cold extrusion robot is equivalent to the productivity of 100 ordinary lathes or 10 four-axis automatic lathes.

  Machinable complex parts

  Such as profiled sections, internal teeth, shaped holes and blind holes, these parts are difficult to complete with other processing methods, extrusion parts with cold extrusion processing is very convenient. The parts shown can be easily extruded. The same time as

  The cold extrusion has high strength, good rigidity and light weight

  As the cold extrusion using metal materials cold deformation of the cold hardening characteristics, that is, extrusion parts during the extrusion process of metal blanks in a three-way compressive stress state, deformation of the material after the dense structure, and has a continuous fiber flow, and thus the strength of the larger parts improve. So that low-strength materials can be used instead of high-strength materials. For example, in the past, the use of 20Cr steel by cutting the manufacture of Jiefang brand piston pin, is to use 20 steel by cold extrusion manufacturing piston pin, the performance of the indicators, cold extrusion method than the cutting method to manufacture piston pin.

  From the above characteristics, we can see that the cold extrusion technology and the current processing methods compared to a prominent advantage. This opens up a broad road for cold extrusion instead of cutting, forging, extrusion parts  casting and drawing processes to make machine parts.
