Through the research on the production process of the middle comb, it is found that there are workpieces that need to be processed in the welding hardening process of the middle comb, that is, the workpieces are bent after hardening welding, which leads to the workpieces having to be bent or reprocessed, and the number of workpieces that need to be processed at present is 77. 94% of the buckling occurs at 8-10mm. By studying the above problems, a scheme of "adjusting the processing efficiency of carding machine" is put forward to reduce the number of workpieces that need to be reworked. Based on the relevant theoretical research, it is found that there are several related factors leading to workpiece buckling in hard welding, mainly welding current, welding wire walking speed and welding workpiece size. In the welding process of the middle comb, there is a support to support the force from the bottom of the comb, and the size of the support will also affect the buckling of the workpiece. In this scheme, a full-factor experiment of two main factors is designed, namely the size of the support (mm). ) and welding wire speed (mm). /sec) to calculate the number of 9 tests and repeat 27 tests to compare the buckling differences of each test.
