Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a novel lower-positioned non-standard inclined wedge mechanism. Background Technology

[0002] As the automotive industry grows stronger, high-strength steel plates are increasingly used in car bodies. High-strength plate molds are a rapidly developing cold stamping process equipment in my country's electromechanical product manufacturing. Considering the rebound of the parts, high-strength plate molds are all equipped with a forming process. Forming is generally divided into front forming and side forming. Side forming is completed by side forming wedges.

[0003] In actual production, for some small parts, the complex molding requirements of general automotive molds often need to be broken down into multiple processes and multiple sets of molds, resulting in a lengthy production process and frequent mold switching. This makes traditional molds prone to structural vibration and component wear under high-speed stamping conditions, which not only limits the production cycle but also leads to a high scrap rate and significantly increases stamping costs. To address these issues, we propose a new type of lower non-standard inclined wedge mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a novel lower-positioned non-standard inclined wedge mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel lower-positioned non-standard inclined wedge mechanism, comprising an upper insert block and a lower drive block. The upper insert block is installed in an upper mold, and the lower drive block is installed in a lower mold. The contact surface between the upper insert block and the lower drive block is an inclined surface. A guide surface is provided at the top of the lower drive block, and a guide slide is installed on the guide surface. A forming slider is installed at the top of the guide slide. A fixing plate is installed at the end of the forming slider away from the guide slide. A forming punch is provided inside the fixing plate. A second reset nitrogen spring is installed on the bottom side of the lower drive block away from the upper insert block, and a first reset nitrogen spring is installed at the end of the forming slider away from the lower drive block.

[0006] As an improved technical solution, the angle between the contact surfaces of the upper insertion block and the lower driving block is 35°-45°.

[0007] As an improved technical solution, a guide slider is installed inside the guide slide, and the fixing plate is slidably connected to the guide slide through the guide slider.

[0008] As an improved technical solution, the forming punch is mounted on the fixed plate via a quick-release assembly.

[0009] As an improved technical solution, the elastic coefficients of the first and second reset nitrogen springs are adjustable.

[0010] As an improved technical solution, wear-resistant pads are installed on the contact surfaces of both the upper insertion block and the lower driving block.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are:

[0012] This invention converts the vertical punching force transmitted by the upper insert block into a normal forming force through the cooperation of the lower drive block and the forming slider. This allows the forming slider to drive the forming punch to perform an oblique forming action on the stamped part plate, ensuring the accuracy and consistency of the oblique surface forming of the stamped part plate. Furthermore, through the second reset nitrogen spring installed on the lower drive block and the first reset nitrogen spring on the forming slider, a fast and stable reset action is achieved, reducing manual intervention, improving the degree of automation, and enabling the entire equipment to complete the complex oblique surface forming in a single stamping. This effectively reduces the number of molds and stamping processes, lowers production costs, and is suitable for the mass production of complex parts in automotive molds.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] This utility model provides a technical solution: such as Figures 1 to 4As shown, in this embodiment, the novel lower non-standard inclined wedge mechanism includes an upper insert block 1 and a lower drive block 2. The upper insert block 1 is installed on the upper mold, and the lower drive block 2 is installed on the lower mold. The contact surface between the upper insert block 1 and the lower drive block 2 is an inclined surface. A guide surface 8 is provided at the top of the lower drive block 2. A guide slide 9 is installed on the guide surface 8. A forming slider 3 is installed at the top of the guide slide 9. A fixing plate 5 is installed at the end of the forming slider 3 away from the guide slide 9. A forming punch 4 is provided inside the fixing plate 5. A second reset nitrogen spring 7 is installed on the bottom side of the lower drive block 2 away from the upper insert block 1. A first reset nitrogen spring 6 is installed at the end of the forming slider 3 away from the lower drive block 2.

[0020] By cooperating with the lower drive block 2 and the forming slider 3, the vertical punching force transmitted by the upper insert block 1 is converted into a normal forming force, allowing the forming slider 3 to drive the forming punch 4 to perform an oblique forming action on the stamped part plate 10, ensuring the accuracy and consistency of the oblique forming of the stamped part plate 10. Then, through the second reset nitrogen spring 7 installed on the lower drive block 2 and the first reset nitrogen spring 6 on the forming slider 3, a fast and stable reset action is achieved, reducing manual intervention, improving the degree of automation, and enabling the entire equipment to complete the complex oblique forming in a single stamping, reducing the number of molds and stamping processes, reducing production costs, and making it suitable for the mass production of complex parts in automotive molds.

[0021] In other embodiments, the angle between the contact surfaces of the upper insertion block 1 and the lower driving block 2 is 35°-45°;

[0022] This design ensures that when the upper insert block 1 moves downward, the lower drive block 2 can efficiently convert the vertical punching force into the normal forming force.

[0023] In other embodiments, a guide slider is installed inside the guide slide 9, and the fixing plate 5 is slidably connected to the guide slide 9 through the guide slider;

[0024] This design allows the fixed plate 5 to move laterally along the inside of the guide slide 9 under the action of the guide slider, restricting the fixed plate 5 to move only along the normal direction of the inclined surface of the stamping part plate 10.

[0025] In other embodiments, the forming punch 4 is mounted on the fixing plate 5 via a quick-release assembly;

[0026] This design allows for quick replacement of the corresponding forming punch 4 based on the part's model, thereby increasing the equipment's applicability.

[0027] In other embodiments, the spring constants of the first reset nitrogen spring 6 and the second reset nitrogen spring 7 are adjustable;

[0028] This design allows for adjustment of the elastic coefficients of the first reset nitrogen spring 6 and the second reset nitrogen spring 7 to quickly adapt to different stamping conditions.

[0029] In other embodiments, wear-resistant pads are installed on the contact surfaces of the upper insertion block 1 and the lower driving block 2;

[0030] This design effectively reduces wear on the contact surfaces of the upper insert block 1 and the lower drive block 2, and allows for quick replacement of the wear-resistant pads on the upper insert block 1 and the lower drive block 2, ensuring their service life.

[0031] This utility model provides a novel lower-positioned non-standard inclined wedge mechanism, the specific working principle of which is as follows:

[0032] Initial stage: The punch press is at the top dead center position, the upper die holder drives the upper insert block 1 to a high position, and the lower drive block 2 and the forming slider 3 are in the initial position under the action of the second reset nitrogen spring 7 and the first reset nitrogen spring 6.

[0033] During the downward stamping stage: the upper die holder moves downward with the press slide, and the upper insert block 1 descends to the bottom dead center, so that the upper insert block 1 applies vertical downward pressure to the lower drive block 2, forcing the lower drive block 2 to move in the horizontal direction, and the lower drive block 2 compresses the second reset nitrogen spring 7 during the movement. At the same time, it pushes the forming slide block 3 to move along the guide slide block 9 on the guide surface 8, so that the forming slide block 3 moves along the normal (perpendicular to the inclined surface direction) of the inclined surface of the stamping part plate 10, and further compresses the first reset nitrogen spring 6, so that the forming slide block 3 drives the forming punch 4 fixed on it to complete the inclined forming action of the stamping part plate 10;

[0034] Reset Phase: After the press slide reaches the bottom dead center, it begins to move upward. The upper die holder drives the upper insert block 1 to rise, relieving the pressure on the lower drive block 2. The second reset nitrogen spring 7 releases its stored elastic force, pushing the lower drive block 2 to horizontally reset to its initial position. At the same time, the first reset nitrogen spring 6 releases its elastic force, pushing the forming slide 3 to move in the opposite direction along the guide surface 8, causing the forming punch 4 to disengage from the stamping part plate 10, completing the reset. When the press slide reaches the top dead center, all components return to their initial state, and a complete stamping stroke ends.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
