Description

Technical Field

[0001] This utility model relates to the field of mold equipment technology, and in particular to a punching composite mold. Background Technology

[0002] After forging, shaft and wheel forgings require punching and trimming. The existing punching and trimming processes use traditional composite dies to complete the punching and trimming processes. Each product requires three actions for the robot to complete punching and trimming: first, feeding the material; second, gripping the product; and third, removing the flash, which takes a total of 12-15 seconds. However, the cycle time for each forging product is 10 seconds. After punching and trimming, a flash removal action is required, causing the cycle time of the punching and trimming process to be mismatched with that of the forging process, affecting production efficiency. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a punching and cutting composite die to solve the problem that after punching and cutting, a flash removal action is required, which leads to a mismatch between the cycle time and the forging forming, thus affecting production efficiency.

[0004] To achieve the above objectives, this utility model provides a punching composite mold, including a top plate and a bottom plate. A lower mold base is mounted on the bottom plate, a punch head is provided on the top plate, an upper mold base is sleeved on the outside of the punch head, a mounting base is provided on the top plate, the lower end of the upper mold base extends from the underside of the mounting base, a trimming die is mounted on the bottom of the mounting base, the trimming die is sleeved on the outside of the upper mold base, a cutting mechanism is provided on the bottom plate and the trimming die, and the trimming mechanism cuts off the flash. A slide is provided on the upper side of the bottom plate.

[0005] A further improvement is that the cutting die has a stepped structure, and a mounting plate is bolted to the lower side of the mounting base, with the cutting die engaging between the mounting base and the mounting plate.

[0006] A further improvement is that the cutting mechanism includes a cutting blade, and two sets of cutting blades are provided. The cutting blades are fixedly installed on the base plate. The two sets of cutting blades are symmetrically arranged on both sides of the lower mold base and attached to the upper mold base. The lower side of the cutting die is provided with a cutting edge corresponding to the cutting blade, and a slide is provided on the upper side of the base plate.

[0007] A further improvement is that a housing is slidably fitted onto the cutting blade, a clamping plate is installed on the top of one side of the housing, and a buffer spring is connected between the housing and the bottom of the cutting blade.

[0008] A further improvement is that the slide is provided in two sets, which are symmetrically arranged on both sides of the lower mold base. The slides are inclined and the ends of the slides are attached to the lower mold base.

[0009] A further improvement is that a sliding groove is provided on the side of the mounting base, and a sliding plate is installed on the upper end of the upper mold base, with the sliding plate slidably disposed in the sliding groove.

[0010] A further improvement is that a guide post is installed on the base plate, and the top plate is slidably mounted on the guide post.

[0011] The beneficial effects of this utility model are as follows: By adding a cutting structure, after the cutting die has finished cutting the flash, the cutting die drives the flash to continue to descend and contact the cutting blade. The cutting blade and the cutting edge work together to cut the flash into two halves. The cut flash slides away along the slide, thus eliminating the need for the robot to pick up the flash, saving time, keeping the production rhythm consistent, and improving the production efficiency of the production line.

[0017] like Figure 1-5 As shown, this embodiment provides a punching composite mold, including a top plate 1 and a bottom plate 2. A guide post 17 is installed on the bottom plate 2, and the top plate 1 is slidably disposed on the guide post 17. The top plate 1 is driven by a hydraulic cylinder to move along the guide post 17 toward the bottom plate 2.

[0018] A lower die holder 3 is mounted on the base plate 2, and a punch head 4 is provided on the top plate 1. An upper die holder 5 is fitted around the outside of the punch head 4, and the lower end of the punch head 4 extends from the underside of the upper die holder 5. When the top plate 1 moves down, the upper die holder 5 and the lower die holder 3 close together, and the punch head 4 punches holes in the workpiece. A discharge hole adapted to the punch head 4 is opened in the middle of the lower die holder 3, and the waste generated by punching is discharged through the discharge hole.

[0019] A mounting base 6 is provided on the top plate 1. The lower end of the upper mold base 5 extends from the lower side of the mounting base 6. A sliding groove 15 is provided on the side of the mounting base 6. A sliding plate 16 is installed on the upper end of the upper mold base 5. The sliding plate 16 is slidably disposed in the sliding groove 15. The upper mold base 5 slides up and down in the mounting base 6 through the cooperation of the sliding plate 16 and the sliding groove 15. An elastic element is provided between the upper side of the sliding plate 16 and the top plate 1. The elastic element causes the upper mold base 5 to contact the lower mold base 3 first and clamp and fix the workpiece during the downward movement of the top plate 1.

[0020] A trimming die 7 is installed at the bottom of the mounting base 6. The trimming die 7 is sleeved on the outside of the upper die base 5. As the mounting base 6 moves down, the trimming die 7 trims the flash of the workpiece held by the upper die base 5 and the lower die base 3. The trimming die 7 has a stepped structure. A mounting plate 9 is installed on the lower side of the mounting base 6 by bolts. The trimming die 7 is snapped between the mounting base 6 and the mounting plate 9. The trimming die 7 is fixed between the mounting plate 9 and the mounting base 6 by the mounting plate 9, which facilitates the installation and replacement of the trimming die 7.

[0021] A cutting mechanism is provided on the base plate 2 and the trimming die 7 to cut off the flash. The cutting mechanism includes two sets of cutting blades 10, which are fixedly mounted on the base plate 2 by bolts. The two sets of cutting blades 10 are symmetrically arranged on both sides of the lower die base 3 and attached to the upper die base 5. The lower side of the trimming die 7 is provided with a cutting edge 11 corresponding to the cutting blade 10. After the trimming is completed, the trimming die 7 drives the flash to continue downward and contact the cutting blade 10. The cutting blade 10 and the cutting edge 11 work together to cut the flash into two halves. A slide rail 8 is provided on the upper side of the base plate 2. Two sets of slide rail 8 are symmetrically arranged on both sides of the lower die base 3. The slide rail 8 is inclined and its ends are attached to the lower die base 3. A housing 12 is slidably mounted on the cutting blade 10. A clamping plate 13 is installed on the top of one side of the housing 12. A buffer spring 14 is connected between the housing 12 and the bottom of the cutting blade 10. The cutting die 7 drives the flash to move downward, and the lower side of the flash contacts the clamping plate 13. By setting the clamping plate 13 in conjunction with the cutting die 7, the flash is clamped, and the cutting die 7 pushes the housing 12 downward, so that the cutting blade 10 extends and cuts the flash with the cutting edge 11, ensuring the stability of flash cutting and improving the cutting effect. The end of the blade head 13 is triangular, and the cutting edge 11 is adapted to the end of the blade head 13.

[0022] During production, the top plate 1 drives the upper mold base 5 to move downward. The upper mold base 5 and the lower mold base 3 close the mold for the workpiece. The punch head 4 punches holes in the workpiece. The trimming die 7 trims the flash. After trimming, the trimming die 7 drives the flash to continue downward and contact the cutting blade 10. The cutting blade 10 and the cutting edge 11 work together to cut the flash into two halves. The cut flash falls onto the slide 8 and slides away along the slide 8, reducing flash cleaning time and improving production efficiency.
