1. Effectively separate two heat sources.
The basic idea is to separate the heat source of the high-speed punching body and reduce the heat. From the perspective of high-speed punching structure design, the structural characteristics of precision punching are comprehensively considered from the three aspects of static stiffness, dynamic stiffness and thermal stiffness. Heat balance design is also to reduce heat. The effective method of deformation, due to different parts materials and different heat capacities, so the heat capacity is large, the warm part should be used, and the temperature rise control or heat transfer method should be used to reduce the temperature difference of other zero systems, so as to achieve the relative balance of the entire high-speed punching temperature .
2. Reduce the heat of the heat source.
For high-speed punching, there is a large relative speed on the relative moving friction surface, which leads to severe friction heating, which not only accelerates the wear and deterioration of parts, but also reduces its service life. In order to reduce heat, the characteristics of each moving surface can be considered, and should be minimized The friction coefficient of high-speed punching surfaces, especially crankshafts and connecting rods, crankshafts and beds, drive shafts and beds should consider reducing frictional heating to reduce heat, and finding new cost-effective materials is a good solution.
3. Strengthen the heat dissipation performance of the high-speed punch.
Improve the heat sink of each heat source of the high-speed punch, increase the heat transfer coefficient, and increase the heat dissipation area.
