Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically a high-precision stamping device. Background Technology

[0002] Stamping is a metal processing method that uses dies and stamping equipment to apply pressure to sheet metal, strip, tube, etc., causing plastic deformation or separation, thereby obtaining parts with the required shape, size and performance.

[0003] In the process of stamping strip, the existing stamping device does not have a limiting and clamping mechanism. When the strip moves to the upper surface of the lower die, it cannot effectively ensure that the strip is in the center position and that the strip position is stable. When the strip position is deviated, it affects the dimensional accuracy and shape consistency of the stamped part. Therefore, a high-precision stamping device is needed to solve the above problems.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This high-precision stamping device, equipped with a drive clamping assembly, allows the rack to move horizontally back and forth when the strip is placed on the upper surface of the lower die. This movement of the rack, via a cylinder, drives the rotating shaft to rotate in either the forward or reverse direction. The rotation of the rotating shaft causes the rotating components to rotate synchronously. This forward or reverse rotation of the rotating components allows the push-pull rod to push the two vertical slide plates away from each other or pull them closer together. When the two vertical slide plates are close together, the clamping plate clamps the strip, ensuring it is centered and improving product quality.

[0016] 2. This high-precision stamping device has guide pillars and guide holes respectively opened on the lower die and the upper die. During the downward movement of the upper die, the guide pillars can be inserted into the guide holes to ensure effective alignment between the lower die and the upper die.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 A high-precision stamping device includes a base 1, a U-shaped base frame 2 is provided at the center of the upper surface of the base 1, a lower die 3 is provided on the upper surface of the U-shaped base frame 2, a stamping frame 4 is provided on the upper surface of the base 1 and outside the U-shaped base frame 2 and the lower die 3, a hydraulic cylinder 5 is provided at the upper end of the stamping frame 4, an upper die 6 is provided inside the stamping frame 4 and above the lower die 3, the lower end of the piston rod of the hydraulic cylinder 5 passes through the upper wall of the stamping frame 4 and is connected to the upper die 6, and a drive clamping assembly 7 is provided inside and outside the U-shaped base frame 2.

[0025] The drive clamping assembly 7 includes two vertical slide plates 707 and two clamping plates 708. The two vertical slide plates 707 are respectively located on both sides of the U-shaped base frame 2, and the two clamping plates 708 are respectively located on the upper inner side of the two vertical slide plates 707.

[0026] The drive clamping assembly 7 further includes a cylinder 701, a rack 702, a rotating shaft 703, and a gear ring 704. The cylinder 701 is located at one end of the upper surface of the base 1. Through holes 201 are provided on both side walls of the U-shaped base 2. The rack 702 is located inside the U-shaped base 2, with one end passing through the through hole 201 and connected to the output end of the cylinder 701. The rotating shaft 703 is located inside the U-shaped base 2, with its upper end connected to the U-shaped base 2. The upper internal wall is rotatably connected, and the lower end of the rotating shaft 703 is rotatably connected to the base 1. The gear ring 704 is fixedly sleeved on the lower end of the outer surface of the rotating shaft 703. The gear ring 704 and the rack 702 mesh with each other. When the strip is placed on the upper surface of the lower die 3, the cylinder 701 works, which can effectively drive the rack 702 to move back and forth in the horizontal direction. The rack 702 moves back and forth in the horizontal direction, which can drive the rotating shaft 703 to rotate in the forward or reverse direction through the gear ring 704.

[0027] The rotating shaft 703 has a rotating component 705 fixedly sleeved on its upper outer surface. Both ends of the rotating component 705 are rotatably connected to push-pull rods 706 via connecting shafts. The end of the push-pull rod 706 away from the rotating component 705 is rotatably connected to a lower connecting rod. The lower end of the vertical slide plate 707 is connected to the lower connecting rod. The vertical slide plate 707 is rotatably connected to the push-pull rod 706 via the lower connecting rod. The rotation of the rotating shaft 703 will drive the rotating component 705 to rotate synchronously. By rotating the rotating component 705 in the forward or reverse direction, the push-pull rod 706 can push the two vertical slide plates 707 away from each other or pull the two vertical slide plates 707 closer to each other. When the two vertical slide plates 707 are close to each other, the clamping plate 708 can clamp the strip and ensure that the strip is in the center position, thereby improving product quality.

[0028] The U-shaped base frame 2 and the lower mold 3 are provided with guide grooves 8 on both sides. The two vertical slide plates 707 are slidably set in the two guide grooves 8. By providing guide grooves 8, the vertical slide plates 707 can be effectively limited, ensuring that the vertical slide plates 707 can move back and forth and preventing them from shifting their position.

[0029] Among them, guide posts 301 are provided at the four corners of the upper surface of the lower mold 3, and guide holes that cooperate with the guide posts 301 are opened at the four corners of the upper mold 6. Support feet are provided at the four corners of the lower surface of the base 1. By opening guide posts 301 and guide holes on the lower mold 3 and the upper mold 6 respectively, the guide posts 301 can be inserted into the guide holes during the downward movement of the upper mold 6, so as to ensure effective alignment between the lower mold 3 and the upper mold 6.

[0030] Working principle: When the strip is placed on the upper surface of the lower die 3, the cylinder 701 works, which can effectively drive the rack 702 to move back and forth in the horizontal direction. The rack 702 moves back and forth in the horizontal direction, which can drive the rotating shaft 703 to rotate in the forward or reverse direction through the gear ring 704. The rotation of the rotating shaft 703 will drive the rotating component 705 to rotate synchronously. The forward or reverse rotation of the rotating component 705 can push the two vertical slide plates 707 away from each other or pull the two vertical slide plates 707 closer together through the push-pull rod 706. When the two vertical slide plates 707 are close to each other, the clamping plate 708 can clamp the strip and ensure that the strip is in the center position, thus improving product quality.

[0031] Furthermore, by providing a guide groove 8, the vertical slide plate 707 can be effectively limited, ensuring that the vertical slide plate 707 moves back and forth and preventing its position from shifting. By providing guide posts 301 and guide holes on the lower mold 3 and the upper mold 6 respectively, the guide posts 301 can be inserted into the guide holes during the downward movement of the upper mold 6, ensuring effective alignment between the lower mold 3 and the upper mold 6.
