Description
Technical Field
[0001] The utility model relates to the technical field of punching machines, in particular to a pre-punching machine for stamping parts. Background Art
[0002] A stamping pre-punch machine is a device specifically designed for pre-punching holes in stamped parts made of metal or other materials. It is typically used in the early stages of the stamping process to improve efficiency and accuracy during subsequent stamping, forming, or assembly. Punching machines used for stamping utilize hydraulic or pneumatic cylinders to drive the extrusion between the punch block and the backing block to complete the cut. Depending on the material and thickness, either pneumatic or hydraulic cylinder can be used as the drive. When punching thinner stamping parts, pneumatic cylinders are often used, offering advantages such as faster punching speed and lower cost.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] Reference Figures 1 to 4 A stamping part pre-punching machine includes a base 2, and bottom plates 9 are movably embedded on both sides of the midpoint of the upper end surface of the base 2. A No. 1 threaded rod 16 is rotatably embedded at the midpoint of one side of the two bottom plates 9. A limit plate 3 is movably embedded inside the midpoint of both sides of the upper end surface of the base 2. A fixed block 15 is provided at the midpoint of both sides of the upper end surface of the base 2. A movable groove 14 is provided on the upper end surface of the base 2 near the front end and the rear end. A No. 1 bidirectional screw 13 is rotatably embedded at the midpoint between the two sides of the interior of the two movable grooves 14. A worm 11 is rotatably embedded on one side of the front end surface of the base 2 near the lower end. Adjustment blocks 19 are threadedly sleeved on both sides of the outer surface of the rod. A No. 2 bidirectional screw 18 is rotatably embedded between the two adjustment blocks 19 on the same side of the four adjusting blocks 19, and a fixing mechanism 8 is threadedly sleeved on the outer surfaces of the two No. 2 bidirectional screws 18.
[0029] Specifically, after the bottom plate 9 is movably embedded on both sides of the upper end surface of the base 2, the punching parts can be better punched and opened by moving the bottom plate 9. At the same time, after the No. 1 threaded rod 16 is rotatably embedded on one side of the bottom plate 9, the bottom plate 9 can be better driven to move. The limit plates 3 embedded at the upper midpoint on both sides of the base 2 can limit and fix the movable and adjustable bottom plate 9. At the same time, after the movable groove 14 is opened on the upper end surface of the base 2, the No. 1 bidirectional screw 13 can be rotatably embedded in the movable groove 14, so that the threaded adjustment block 19 can be driven to move when the No. 1 bidirectional screw 13 rotates. At the same time, a No. 2 bidirectional screw 18 is rotatably embedded between the two adjustment blocks 19 on the same side. The fixing mechanism 8 threadedly sleeved on the outer surface of the No. 2 bidirectional screw 18 can better fix the position of the punching parts after adjustment and movement.
[0030] Reference Figure 7 and Figure 8 The rotating cylinder 804 is rotatably embedded in the midpoint of one side of the upper end face of the connecting block 801, the No. 2 threaded rod 803 is threadedly embedded in the inner surface of the rotating cylinder 804, the limiting member 805 is fixedly set on one side of the lower end face of the connecting block 801, the No. 2 threaded rod 803 movably passes through one side of the lower end face of the connecting block 801, the limiting member 805 is movably sleeved on the outer surface of the No. 2 threaded rod 803, the connecting block 801 is fixedly set on the upper end face of the movable block 802, and the movable block 802 is threadedly sleeved on the outer surface of the No. 2 bidirectional screw 18.
[0031] Specifically, after the rotating cylinder 804 and the second threaded rod 803 that are rotatably embedded in the upper end surface of the connecting block 801 are threadedly connected, the rotating cylinder 804 can drive the threaded rod to be raised and lowered, and then after the limiting piece 805 fixed on the lower end surface of the connecting block 801 is movably sleeved on the outer surface of the second threaded rod 803, the protruding parts of the inner wall of the limiting piece 805 near the front and rear ends can be engaged with the grooves opened on the outer surface of the second threaded rod 803 near the front and rear ends, so that the threaded rod can be effectively prevented from rotating during adjustment by the limiting piece 805. The rubber block 806 fixed on the lower end surface of the second threaded rod 803 can better fix the stamping part. After the upper end surface of the movable block 802 is fixed on the connecting block 801, the second bidirectional screw 18 can be better rotated to drive the movable block 802 to move its position.
[0032] Reference Figure 4 The two No. 1 threaded rods 16 rotate through the midpoints on both sides of the base 2 respectively, and a stopper 17 is fixedly provided at the midpoint of one side of the upper end surface of the two bottom plates 9. The lower end surfaces of the movable blocks 802 in the four adjustment mechanisms are respectively fitted with the upper end surfaces of the two bottom plates 9.
[0033] Specifically, after rotating the No. 1 threaded rod 16 and passing through one side of the base 2, the bottom plate 9 can be driven to move and adjust after rotating the No. 1 threaded rod 16. The stop block 17 fixed on the upper end surface of the bottom plate 9 can fit with the limit plate 3, thereby limiting the movement of the bottom plate 9.
[0034] Reference Figure 6 A movable rod 22 is fixedly provided at the midpoint of the lower end surface of the two fixed blocks 15. The two movable rods 22 are movably embedded in the interior of the midpoints on both sides of the upper end surface of the base 2. The outer surfaces of the two movable rods 22 located inside the base 2 are fixed with springs 23.
[0035] Specifically, after the movable rod 22 is fixed on the lower end face of the fixed block 15, the movable rod 22 can be movably embedded in one side of the upper end face of the base 2. At the same time, after the spring 23 is sleeved on the outer surface of the movable rod 22 in the base 2, the fixed block 15 can be rebounded and reset.
[0036] Reference Figure 5 and Figure 6 The lower end surfaces of the two fixed blocks 15 are fixed with positioning blocks 24 near the front end and the rear end, and multiple positioning grooves 21 are opened on both sides of the upper end surfaces of the two limit plates 3. The two positioning blocks 24 fixed on the lower end surfaces of the two fixed blocks 15 are respectively engaged with the positioning grooves 21 opened on the upper end surfaces of the two limit plates 3, and the upper end surfaces of the two limit plates 3 are embedded with scale plates 20.
[0037] Specifically, after the positioning block 24 is fixedly set on the lower end face of the fixed block 15, it can be engaged with the positioning groove 21 opened on the upper end face of the limit plate 3, so that the fixed block 15 can fix the position of the limit plate 3 through the positioning block 24. After the scale plate 20 is embedded in the upper end face of the limit plate 3, the position of the limit plate 3 can be moved more accurately.
[0038] Reference Figure 3 and Figure 4 A worm gear 12 is fixedly sleeved on one side of the outer surface of the two No. 1 bidirectional screws 13. The two worm gears 12 are respectively engaged with the outer surface of the worm 11 at the front end and the rear end. The movable blocks 802 in the four fixing mechanisms 8 are all movably set in the two movable grooves 14.
[0039] Specifically, after the worm wheel 12 is fixedly sleeved on one side of the two No. 1 bidirectional screws 13, the worm 11 and the worm wheel 12 can be meshed and connected, so that the worm 11 can drive the No. 1 bidirectional screw 13 to rotate. When the No. 1 bidirectional screw 13 rotates, it can better drive the threaded movable block 802 to move and adjust in the opened movable groove 14.
[0040] Reference Figure 1 and Figure 2 A support frame 1 is fixedly provided on the upper end surface of the base 2, a fixing frame 5 is fixedly provided at the midpoint of the upper end surface of the support frame 1, an electric telescopic rod 6 is fixedly provided at the midpoint of the lower end surface of the fixing frame 5, a stamping device 7 is fixedly provided on the lower end surface of the electric telescopic rod 6, and a stamping head 10 is clamped on the lower end of the stamping device 7, and support plates 4 are fixedly provided on both sides of the lower end surface of the base 2.
[0041] Specifically, after the support frame 1 is fixedly installed on the upper end surface of the base 2, it can support the fixed fixed frame 5. At the same time, after the electric telescopic rod 6 is fixedly installed on the lower end surface of the fixed frame 5, the stamping device 7 fixed on the lower end surface of the electric telescopic rod 6 can be adjusted to different heights. At the same time, after the punching head 10 is clamped and installed near the lower end of the punching device 7, the stamping parts can be punched and opened. The support plates 4 fixed on both sides of the lower end surface of the base 2 can support and fix the punching machine.
[0042] Working principle: When in use, the user can place the stamping parts that need to be stamped on the upper end of the base plate 9. At the same time, the user can move and adjust the two limit plates 3 according to the size of the punching required. The base plate 9 can be moved to the position of the limit plate 3 by rotating the two No. 1 threaded rods 16. At the same time, after the movement and adjustment are completed, the worm 11 can be rotated according to the size of the stamping parts to drive the two No. 1 bidirectional screws 13 to rotate, and can also drive the adjustment block 19 threadedly sleeved on the outer surface of the No. 1 bidirectional screw 13 to move. After the adjustment block 19 is moved, the No. 2 threaded rod 803 set between the two adjustment blocks 19 on the same side can be rotated to move the set fixing mechanism 8, so that the stamping parts can be better fixed by adjusting the fixing mechanism 8. After the stamping parts are fixed, the electric telescopic rod 6 and the stamping device 7 can be started to punch holes in the stamping parts.
