Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and in particular relates to a cam system that moves around an axis inside a stamping die. Background Technology

[0002] Traditional negative angle bending processes rely on a filler slider mechanism for smooth bending and product ejection. This method involves complex mold structures, intricate machining of the slider and other components, and a slow ejection time due to the need for the filler wedge to reset after bending, thus reducing production speed. This project addresses this by driving the filler slider with rollers, changing its movement from a straight line along the bending direction to a curved motion around an axis. This results in faster product ejection and a simpler structure, saving on machining costs and time. Utility Model Content

[0003] The purpose of this invention is to provide a cam system that moves around an axis inside a stamping die, aiming to solve the technical problem in the existing technology where, after the bending is completed, the filling wedge needs to be reset before the product can be ejected, resulting in slow product ejection time and reduced production speed.

[0004] To achieve the above objectives, this utility model provides a cam system for rotational movement within a stamping die, comprising a lower die base, a rotary filling slider, a drive slider, and a drive assembly. Fixed plates extend upwards from both ends of the lower die base, and a mounting groove is provided between the two fixed plates. The length of the mounting groove is longer than the length of the rotary filling slider. The rotary filling slider is rotatably connected within the mounting groove, and rotates left or right around its rotational connection point to abut against the two fixed plates. A clearance groove is provided at the upper end of the rotary filling slider, with a bending portion at the right end and an abutment portion at the left end. The drive slider is positioned above the rotary filling slider, extending into or out of the clearance groove. A bending punch is provided at one end of the drive slider near the bending portion, cooperating with the bending portion to bend the product. The other end of the drive slider abuts against the abutment portion. The drive assembly is located at the lower end of the rotary filling slider and drives the rotary filling slider to rotate to abut against the two fixed plates.

[0005] Furthermore, a swinging rotating shaft is rotatably connected to the rotary filling slider, and the swinging rotating shaft is connected to the lower mold base, so that the rotary filling slider rotates around the swinging rotating shaft.

[0006] Furthermore, a polyurethane spring is provided at one end of the drive slider near the abutment part, and the polyurethane spring is used to abut the abutment part.

[0007] Furthermore, the drive assembly includes a drive cylinder and a roller assembly. The drive cylinder is located at the lower end of the rotating filling slider, and the roller assembly is connected to the drive end of the drive cylinder. The drive cylinder is used to drive the roller assembly to abut against or move away from the rotating filling slider, so that the rotating filling slider rotates.

[0008] Furthermore, the roller assembly includes a connecting block and a rotating roller shaft. The bottom of the rotating filling slider is provided with an abutment block. The rotating roller shaft is rotatably mounted on the connecting block. The driving end of the driving cylinder is connected to the connecting block. The driving cylinder is used to drive the rotating roller shaft to abut or release the abutment block.

[0009] Furthermore, the abutment block has a guide slope at one end near the rotating roller shaft, and the guide slope extends downward at an angle along the direction of the rotating roller shaft to the direction of the guide slope.

[0010] The above-mentioned technical solutions of one or more of the cam systems for rotational motion within a stamping die provided by this utility model embodiment have at least one of the following technical effects: Under the action of the driving component, the rotating filling slider can rotate left or right around its rotation connection point, thereby abutting against two fixed plates and achieving rapid ejection of the negative angle bent product. The upper end of the rotating filling slider is provided with a clearance groove, and a bending part is provided at the right end of the clearance groove, while an abutting part is provided at the left end of the clearance groove. The driving slider and the rotating filling slider are fitted together within the clearance groove, allowing the driving slider to extend into or out of the clearance groove. A bending punch is provided at one end of the driving slider near the bending part, cooperating with the bending part for bending the product. The other end of the driving slider abuts against the abutting part, thereby driving the rotating filling slider to move around the axis through the action of the driving slider, thus quickly ejecting the bent product from the die. The driving component drives the rotating filling slider to rotate around the axis, achieving rapid ejection when bending the product at a negative angle, and also utilizes the transmission action between the driving slider and the rotating filling slider to complete the bending process. This design not only simplifies the structure and reduces processing time and cost, but also improves the production efficiency and quality of negative angle bending products. The invention has a relatively simple structure, requiring no complex mechanical components or high-precision machining, thus reducing costs and shortening processing time. Therefore, it effectively solves the technical problems of low production efficiency, high cost, and complex processing of negative angle bending products in existing technologies.

[0019] In one embodiment of this utility model, such as Figures 1-2As shown, a cam system for rotating around an axis within a stamping die is provided, including a lower die holder 100, a rotary filling slider 200, a drive slider 300, and a drive assembly 400. Fixed plates 110 extend upwards from both ends of the lower die holder 100, and a mounting groove 120 is provided between the two fixed plates 110. The length of the mounting groove 120 is longer than the length of the rotary filling slider 200. The rotary filling slider 200 is rotatably connected within the mounting groove 120, and the rotary filling slider 200 rotates left or right around its rotational connection point to abut against the two fixed plates 110. The upper end of the rotary filling slider 200 is provided with a clearance groove 210, the right end of the clearance groove 210 is provided with a bending portion 211, and the left end of the clearance groove 210 is provided with an abutment portion 212. The driving slider 300 is disposed above the rotary filling slider 200, and the driving slider 300 extends into or out of the clearance groove 210. The end of the driving slider 300 near the bending portion 211 is provided with a bending punch 310, which cooperates with the bending portion 211 to bend the product. The other end of the driving slider 300 is used to abut the abutment portion 212. The driving assembly 400 is disposed at the lower end of the rotary filling slider 200 and is used to drive the rotary filling slider 200 to rotate to abut against the two fixed plates 110. In this embodiment, under the action of the driving assembly 400, the rotary filling slider 200 can rotate left or right around its rotation connection point, thereby abutting against the two fixed plates 110 and realizing the rapid release of the negative angle bent product. The upper end of the rotary filling slider 200 is provided with a clearance groove 210, and a bending part 211 is provided at the right end of the clearance groove 210, while an abutment part 212 is provided at the left end of the clearance groove 210. The drive slider 300 is fitted into the clearance groove 210 and can extend into or out of the clearance groove 210. One end of the drive slider 300 near the bending part 211 is provided with a bending punch 310, which cooperates with the bending part 211 to bend the product. The other end of the drive slider 300 abuts against the abutment part 212. Thus, the movement of the drive slider 300 drives the rotary filling slider 200 to move around an axis, thereby quickly removing the bent product from the mold. The drive assembly 400 drives the rotary filling slider 200 to rotate around an axis, achieving rapid removal when bending the product at a negative angle. It also utilizes the transmission motion between the drive slider 300 and the rotary filling slider 200 to complete the bending process. This design not only simplifies the structure and reduces processing time and cost, but also improves the production efficiency and quality of negative angle bending products. The invention has a relatively simple structure, requiring no complex mechanical components or high-precision machining, thus reducing costs and shortening processing time. Therefore, it effectively solves the technical problems of low production efficiency, high cost, and complex processing of negative angle bending products in existing technologies.

[0020] Furthermore, a swing rotation shaft 220 is rotatably connected to the rotary filling slider 200. The swing rotation shaft 220 is connected to the lower mold base 100, and the rotary filling slider 200 rotates around the swing rotation shaft 220. In this embodiment, the rotary filling slider 200 rotates around the swing rotation shaft 220, causing it to abut against the two fixed plates 110 in different directions. This allows the rotary filling slider 200 to be in different positions when the product is bent and when it is removed, facilitating product bending and removal.

[0021] Furthermore, a polyurethane spring 320 is provided at one end of the drive slider 300 near the abutment portion 212, and the polyurethane spring 320 is used to abut the abutment portion 212. In this embodiment, the drive slider 300 and the rotating filling slider 200 abut against each other by means of the polyurethane spring 320. The polyurethane spring 320 is elastic, which avoids damage caused by rigid contact between the drive slider 300 and the rotating filling slider 200.

[0022] Furthermore, the drive assembly 400 includes a drive cylinder 410 and a roller assembly 420. The drive cylinder 410 is disposed at the lower end of the rotating filling slider 200, and the roller assembly 420 is connected to the drive end of the drive cylinder 410. The drive cylinder 410 is used to drive the roller assembly 420 to abut against or move away from the rotating filling slider 200, so that the rotating filling slider 200 rotates. In this embodiment, when the product is to be stamped, the drive cylinder 410 drives the roller assembly 420 not to abut against the rotating filling slider 200. At this time, the drive slider 300 abuts against the abutting part 212, and the rotating filling slider 200 rotates to abut against the two fixed plates 110. Then, the bending punch 310 and the bending part 211 cooperate to bend the product. After the product is stamped, the drive slider 300 exits the clearance groove 210, and then the drive cylinder 410 drives the roller assembly 420 to abut against the rotating filling slider 200, so that the rotating filling rotates to abut against the two fixed plates 110 from another direction. At this time, the bending part 211 flips out, which facilitates the product unloading.

[0023] Furthermore, the roller assembly 420 includes a connecting block 421 and a rotating roller shaft 422. The bottom of the rotating filling slider 200 is provided with an abutment block 230. The rotating roller shaft 422 is rotatably mounted on the connecting block 421. The driving end of the drive cylinder 410 is connected to the connecting block 421, and the drive cylinder 410 is used to drive the rotating roller shaft 422 to abut or release the abutment block 230. In this embodiment, by abutting or releasing the abutment block 230 with the rotating roller shaft 422, the rotation of the rotating filling slider 200 is controlled, making the contact between the rotating roller shaft 422 and the abutment block 230 more stable.

[0024] Furthermore, the abutment block 230 has a guide slope 231 at one end near the rotating roller shaft 422. The guide slope 231 extends downward at an angle along the direction of the rotating roller shaft 422. In this embodiment, the guide slope 231 and the rotating roller shaft 422 cooperate with each other. By abutting or releasing the abutment block 230 through the rotating roller shaft 422, the rotation of the rotating filling slider 200 is controlled, making the contact between the rotating roller shaft 422 and the abutment block 230 more stable.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
