DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a stamping device for producing motor punching sheets, including a lower die base 1 and a base 12. A mold 2 is arranged on the top of the lower die base 1. First, the lower die base 1 is placed in a suitable position, and the punching sheet is placed on the top of the mold 2. The four corners of the mold 2 are slidably connected with fixed columns 3. The fixed columns 3 are placed inside the four corners of the mold 2. A cavity 4 is opened inside the fixed column 3. An adjustment component is arranged inside the cavity 4. The adjustment component includes a handle 5, a top column 6 and a spring 7. The outer thread of the handle 5 is connected to the inside of the fixed column 3. Then, the handle 5 is turned, and the other end of the spring 7 contacts with the bottom of the handle 5. When the handle 5 is turned, the spring 7 will be compressed downward.

[0033] The inner wall of the cavity 4 is slidably connected with a top column 6, and the top of the top column 6 is fixedly connected with a spring 7. At this time, the spring 7 will squeeze the top column 6, and the left and right sides of the bottom of the fixed column 3 are rotatably connected with balls 8. The top column 6 will squeeze the balls 8 to both sides when sliding. Circular grooves 9 are provided on the left and right sides of the bottom of the fixed column 3. At this time, the balls 8 will rotate on the inner wall of the circular groove 9 and move to both sides. The outside of the balls 8 is rotatably connected to the inner wall of the circular groove 9. A plurality of slots 10 are provided on the top of the lower die base 1. When the balls 8 contact the slots 10, the handle 5 is stopped from rotating. The outside of the fixed column 3 is slidably connected to the inner wall of the slots 10. At this time, the balls 8 are engaged with the slots 10, so that the mold 2 can be fixed on the lower die base 1, and dies of different shapes and sizes can be quickly replaced to meet the production needs of motor punching sheets of different specifications.

[0034] Reference Figure 1 , Figure 2 and Figure 4The bottom of the lower die base 1 is fixedly connected with a bearing plate 11, and the left and right sides of the top of the base 12 are fixedly connected with a support frame. By starting the hydraulic cylinder 21, the outside of the support frame is slidably connected with the hydraulic cylinder 21, and the driving end of the hydraulic cylinder 21 is fixedly connected with a punch head 22. Under the drive of the hydraulic cylinder 21, the punch head 22 moves downward. When the punch head 22 enters the interior of the mold 2 downward, the punching sheet is processed. A placement groove 13 is opened in the middle of the fixed capital of the base 12, and the outside of the bearing plate 11 is slidably connected to the inner wall of the placement groove 13. The lower die base 1 moves downward, and the bottom of the lower die base 1 will be close to the inner wall of the placement groove 13.

[0035] Two buffer components are arranged inside the base 12, and the buffer components include a circular slide groove 14, a damper 15, a second spring 16 and a sliding column 17. The circular slide groove 14 is opened inside the base 12, and the bottom of the circular slide groove 14 is fixedly connected with the damper 15, the outer sleeve of the damper 15 is provided with a second spring 16, and the top of the damper 15 is fixedly connected with the sliding column 17. At this time, the sliding column 17 moves downward, one end of the second spring 16 is fixedly connected to the bottom of the circular slide groove 14, and the other end of the damper 15 is fixedly connected to the bottom of the sliding column 17. The sliding column 17 squeezes the damper 15 and the second spring 16 during the movement.

[0036] The damper 15 and the spring two 16 cooperate with each other to absorb the impact force brought by the sliding column 17. Square slide grooves 18 are provided on the left and right sides of the base 12. A spring three 19 is fixedly connected to one side of the inner side of the square slide groove 18. At the same time, the blocking column 20 is forced to squeeze the spring three 19 to both sides. The other end of the spring three 19 is fixedly connected to the blocking column 20. The spring three 19 is compressed to absorb the external force of the blocking column 20. The outer side of the blocking column 20 is slidably connected to the inner wall of the square slide groove 18, which further reduces the impact force of the bearing plate 11 and can buffer the bottom of the lower mold base 1 and the top of the base 12, thereby extending the service life of the lower mold base 1.

[0037] Working principle: first, place the lower die base 1 in a suitable position, place the punch on the top of the die 2, place the fixing column 3 inside the four corners of the die 2, and then turn the handle 5. The rotation of the handle 5 will compress the spring 7 downward, and the spring 7 will squeeze the top column 6. The top column 6 will squeeze the ball 8 to both sides when sliding. At this time, the ball 8 will rotate on the inner wall of the circular groove 9 and move to both sides. When the ball 8 contacts the slot 10, stop turning the handle 5. At this time, the ball 8 is engaged with the slot 10, so that the die 2 can be fixed on the lower die base 1, and then the liquid is started. The pressure cylinder 21 drives the punch head 22 to move downward. When the punch head 22 enters the interior of the mold 2 downward, the punching sheet is processed. At this time, the bottom of the lower mold base 1 will be close to the inner wall of the placement groove 13. At this time, the sliding column 17 moves downward. The sliding column 17 squeezes the damper 15 and the spring 2 16 during the movement. The damper 15 and the spring 2 16 cooperate with each other to absorb the impact force brought by the sliding column 17. At the same time, the blocking column 20 is forced to squeeze the spring 3 19 to both sides. The spring 3 19 is compressed and absorbs the external force of the blocking column 20, thereby further reducing the impact force of the bearing plate 11.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
