Description

Technical Field

[0001] This utility model belongs to the field of composite mold technology, and in particular relates to a composite mold for punching drive wheel forgings. Background Technology

[0002] Compound dies are a special type of stamping die. Their core feature is that two or more different stamping processes can be completed in one stamping stroke at the same station of the die, which can significantly shorten the production cycle and improve the dimensional accuracy of parts.

[0003] However, current processing of drive wheel forgings requires separate edge trimming, punching, and shaping, making integrated processing difficult. Using multiple sets of dies for step-by-step operations affects product appearance and subsequent assembly. Furthermore, repeated clamping of multiple processes can cause forging deformation and reduce production efficiency. Therefore, we propose a composite die for punching and cutting drive wheel forgings. Utility Model Content

[0031] Example 6: This example provides a composite die for punching a drive wheel forging.

[0032] The two sets of mounting ports 22 provide an assembly base for the relevant components.

[0033] Working principle: First, the drive wheel forging is placed on the trimming die 17, and the operator presses the equipment button. The upper working plate 2 drives the upper base plate 13 and the trimming die 18 and other upper die assemblies to move downwards. During the movement, the three guide pillars 4 and the three guide sleeves 5 slide together to guide the movement. Then, the trimming die 18 transmits pressure downwards and cooperates with the trimming die 17 to shear the flash of the drive wheel forging. At the same time, the drive wheel forging moves downwards with the pressure, and its punched edge contacts the punch 10. Under the relative force between the trimming die 18 and the punch 10, the punched edge is cleanly sheared. After trimming and punching are completed, the forging is finished. Under the pressure of the upper die 18, the drive wheel forging contacts the lower die 11, and the two are squeezed to shape the forging. After the upper die completes the processing, it returns to the starting point. The linear spring 20 releases its elastic force, pushing the stripper block 16 to push out the punched skin. At the same time, the rectangular spring 19 generates a counter-pushing force, which drives the stripper plate 12 to push the flash out of the edge of the upper die 18 and drop it into the tooling area. The operator then collects it into the scrap box. When ejecting the material, the hydraulic cylinder 3 is activated to drive the tray 14 and four ejector rods 15 through the four through holes 21 to push the lower die 11 upward, and finally the drive wheel forging is taken out of the lower die 17.
