Sleeve type component coiling classified circling device and method

Abstract

The invention relates to a sleeve type component coiling classified circling device and method. The circling device is arranged on pipe coiling machine equipment and comprises a first classified circling die, a second classified circling die, a third classified circling die and a classified circling die fixing base, and after mechanisms are matched in a coordinative manner for coiling, a sleeve ispushed into the classified circling dies through circling nails to be subjected to circling work. After being arranged and combined from top to bottom, the three classified circling dies are arrangedin the classified circling die fixing base, the first classified circling die is located at the uppermost end, the second classified circling die is located at the middle position, and in addition, the third classified circling die is located on the bottommost layer. According to the sleeve type component coiling classified circling device and method, the work process is simple, operation is easy, later producing and maintaining are easy, the sleeve coiling effect is good, the bad phenomena of large-head end face and small-head end face galling and the like can be effectively avoided, the performance is stable, and the production efficiency is not influenced.

Description

technical field [0001] The invention belongs to the field of cold processing of chain parts, and in particular relates to a rolling, grading and rounding device for sleeve parts. Background technique [0002] The sleeves rolled by the existing sleeve rolling and rounding technology cannot meet the needs of high-end chain parts. The produced sleeve parts have shortcomings such as large and small ends, uneven outer diameter dispersion, and poor roundness. All chains have high requirements on wear elongation, especially the internal working conditions of automobile engines have higher requirements on the quality of timing chains. In order to reduce the wear elongation of chains, it is urgent for us to improve the rolling accuracy of sleeve parts and reduce rolling friction. force. To reduce the chain wear elongation. Contents of the invention [0003] The purpose of the present invention is to realize the rolling of high-quality sleeve parts through the multi-stage rounding...
