Description

Technical Field

[0001] The utility model relates to the technical field of automobile part stamping, and particularly relates to a blanking concave die seat with punching on both sides. Background Art

[0002] In automobile chassis parts, when there is a need for hole processing on the symmetric two sides of a part, a punching device is used. In this case, a concave die base is often used, and punching heads are placed on both sides for simultaneous punching. This method can greatly improve the punching efficiency. The waste materials generated after punching fall from the slideway inside the concave die. In actual production, efforts are made to make the punching heads on both sides punch simultaneously, but there is still a time difference in the punching sequence, resulting in the waste materials not being generated simultaneously. The waste materials generated first bounce towards the inner side of the concave die and collide with the waste materials generated later or the inner wall. In this case, it is very easy to cause the situation of waste material jamming, resulting in the accumulation of waste materials inside the concave die, the inability of the waste materials to fall, and the damage of the concave die. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a blanking concave die seat with punching on both sides. By arranging a baffle block at the position between two punching heads of a component, it is ensured that the waste materials generated by the two punching heads will bounce onto the baffle block, and the two waste materials do not interfere with each other. After contacting the baffle block, the force of the waste materials bouncing off is offset by the baffle block, and the waste materials slide down from the waste material groove, avoiding the generation of waste materials.

[0004] To achieve the above object, a blanking concave die seat with punching on both sides is designed, including a concave die seat. A horizontal counter punching hole is arranged inside the concave die seat. A punching head one and a punching head two that are matched with the counter punching hole are respectively arranged on the left and right sides of the concave die seat. One end of a waste material groove is arranged below the counter punching hole, and the other end of the waste material groove is connected to the bottom of the concave die seat. One end of a baffle block is threadedly connected downward from the top end of the concave die seat, and the other end of the baffle block is arranged in the counter punching hole. Oblique edges are respectively arranged on both sides of the lower end of the baffle block.

[0005] The punching head one and the punching head two are concentric with the counter punching hole.

[0006] During the punching process of the punching head one and the punching head two, waste material one and waste material two are respectively formed in the counter punching hole.

[0007] The counter punching hole and the waste material groove are vertically distributed with respect to each other.

[0008] A threaded hole one for the baffle block to pass through is arranged at the top end of the concave die seat.

[0009] A plurality of threaded holes two for fixing are arranged at the bottom end of the concave die seat.

[0010] Compared with the prior art, the utility model adds a simple device, ensures that the waste materials do not interfere with each other, ensures the smooth sliding of the waste materials, has a simple structure, and solves the problem of material blockage caused by the collision of waste materials.

[0017] The following further describes the present utility model according to the attached drawings.

[0018] As Figure 3 shown, punch one 1 and punch two 2 are respectively arranged on the left and right sides of the female die seat 3. Punch one 1 and punch two 2 respectively pass through the counter punch hole 9 of the female die seat 3 on the left and right sides of the female die seat 3. In actual production, the punch one 1 and punch two 2 on both sides will be made to punch holes simultaneously as much as possible. One end of the waste chute 4 is arranged below the counter punch hole 9. The waste chute 4 collects the waste generated after punching and drops from the slideway of the waste chute 4 inside the female die seat 3. The other end of the waste chute 4 is connected to the bottom of the female die seat 3. The top end of the female die seat 3 is threadedly connected to one end of the stop block 7. The other end of the stop block 7 is arranged in the counter punch hole 9. The two sides of the lower end of the stop block 7 are respectively provided with bevel edges 10. Part of the stop block 7 vertically blocks the middle section of the counter punch hole 9. Due to the perpendicular relationship between the counter punch hole 9 and the waste chute 4, the bevel edges 10 on both sides of the stop block 7 are used to make the waste slide down smoothly, ensuring that waste one 5 and waste two 6 can fall into the waste chute 4 without causing additional waste jamming problems. The stop block 7 is connected to the female die seat 3 by threads to prevent waste one 5 and waste two 6 from scattering and splashing after being ejected by punching.

[0019] Punch one 1 and punch two 2 are concentric with the counter punch hole 9.

[0020] During the punching process of punch one 1 and punch two 2, waste one 5 and waste two 6 are respectively formed in the counter punch hole 9. Waste one 5 and waste two 6 are mostly the debris dropped from the female die seat 3 under the impact of punch one 1 and punch two 2.

[0021] The counter punch hole 9 and the waste chute 4 are perpendicularly distributed to each other.

[0022] As Figure 4As shown, a first threaded hole 8 through which a stop block 7 passes is provided at the top end of the female die base 3.

[0023] A plurality of second threaded holes 11 for fixing are provided at the bottom end of the female die base 3.

[0024] In the specific implementation process, screws are tightened in the second threaded holes 11 on both sides of the female die base 3 to fix the female die base 3, and the stop block 7 is threadedly connected above the female die base 3 through the first threaded hole 8. There is an inclined edge 10 at the lower end of the stop block 7. When the punching operation starts, as Figure 2 shown, when the first punch 1 and the second punch 2 perform punching on both sides of the female die base 3, waste materials 5 and 6 are generated on the left and right sides respectively during the punching of the product. There is usually a time difference between the punching of the first punch 1 and the second punch 2, and the waste materials 5 and 6 are generated successively. Under the action of the first punch 1 and the second punch 2, the waste materials 5 and 6 fly into the punching hole 9 successively from opposite directions. The waste materials 5 and 6 collide with the stop block 7 successively, and the inclined edge 10 of the stop block 7 bounces the waste materials 5 and 6 downward. The waste materials 5 and 6 will slide down smoothly along the waste material groove, and the punching is successfully completed, avoiding the damage of the female die base 3 caused by the accumulation of materials inside the female die base 3 due to the blockage of materials after the waste materials on both sides collide with each other and cannot fall.
