[0028] The present utility model discloses an auxiliary tooling for preventing deformation during punch grinding.

[0029] Refer to Figures 1 to 4, An auxiliary tooling for preventing deformation during punch grinding, which includes a bottom plate 1 and a fixed mounting block 4 provided on the bottom plate 1. Two pulleys 5 are rotatably connected to the fixed mounting block 4. The two pulleys 5 have the same height, shape and size. The wheel surfaces of the two pulleys 5 are used to contact the bottom of the punch to support the punch. By supporting the punch with the two pulleys 5, the problems of easy deformation and breakage of small punches during grinding are solved, reducing the material and time costs required for punch processing, thereby reducing labor costs and improving production efficiency.

[0030] Specifically, the bottom plate 1 is provided with a sliding groove 11 in the vertical direction. An adjusting block 2 slides in the sliding groove 11, and the adjusting block 2 is relatively fixed to the bottom plate 1 through a locking member. The locking member includes a brass lock piece 12 and a locking bolt 13. The brass lock piece 12 is fixedly connected to the bottom plate 1, and the locking bolt 13 is threadedly connected to the brass piece. The head of the locking bolt 13 is used to abut against the adjusting block 2 so as to lock the adjusting block 2 after the adjusting block 2 is adjusted to the corresponding height. Through the setting of the adjusting block 2, the self-adjustment of the height of the pulley 5 is realized, so as to adapt to punches of different models and sizes, thereby reducing the scrap rate of punch processing.

[0031] More specifically, a sliding groove 21 is provided in the adjusting block 2. A top block 3 is provided below the fixed mounting block 4. The top block 3 includes a large end 31 and a small end 32 integrally formed. The small end 32 is bolted to the fixed mounting block 4, and the large end 31 slides in the sliding groove 21. An elastic member 33 is provided between the large end 31 of the top block 3 and the bottom wall of the sliding groove 21. The elastic member 33 applies a pressure to the top block 3 to move the fixed mounting block 4 away from the bottom plate 1, so that the pulley 5 fits the bottom of the punch. An installation groove 23 is formed on the bottom wall of the sliding groove 21. One end of the elastic member 33 is connected to the installation groove 23, and the other end abuts against the bottom wall of the large end 31 of the top block 3. The elastic member 33 can adopt a linear compression spring.

[0032] It should be noted that a cover plate 22 is fixedly connected to the top of the adjusting block 2 by bolts. The cover plate 22 is used to abut against the top surface of the large end 31 to prevent the top block 3 from disengaging from the sliding groove 21. Since the fixed mounting block 4 and the small end 32 of the top block 3 are bolted, the fixed mounting block 4 can rotate relative to the top block 3 to adjust the axial direction of the two pulleys 5 to better adapt to punches in different directions.

[0033] Working principle: By supporting the punch with the two pulleys 5, the problems of easy deformation and breakage of small punches during grinding are solved, reducing the material and time costs required for punch processing, thereby reducing labor costs and improving production efficiency. Through the setting of the adjusting block 2 and the elastic member 33, the self-adjustment of the height of the pulley 5 and the self-adhesion to the punch are realized, and the effective support for punches of different models and sizes is realized, thereby reducing the scrap rate of punch processing.
