Description

Technical Field

[0001] This utility model belongs to the field of stamping equipment technology, and in particular relates to a limit adjustment device for stamping dies. Background Technology

[0002] Stamping dies, also known as punch dies, hardware dies, or metal stamping dies, are pressure processing methods that use dies fixed on punch presses or presses to apply a certain pressure to metal or non-metal sheets, causing the material to separate or be formed, thereby obtaining parts with certain dimensional requirements and qualified appearance quality.

[0003] For example, application number CN201910725167.7 discloses a stamping die, including a base plate, a fixed frame, a stamping die assembly, and an adjusting device. The fixed frame, which has a U-shaped structure, is mounted on the upper end of the base plate. The stamping die assembly is located on the upper end of the fixed frame, and an adjusting mechanism is installed inside the fixed frame, connected to the outside of the stamping die assembly. This invention solves the problems of existing equipment being unable to adjust according to changes in the size of the workpiece during stamping, resulting in the stamping die not fitting the workpiece properly. Furthermore, the low stability of the stamping die forces the workpiece to move, leading to stamping failure. However, in the aforementioned stripping structure, the adjusting device is located on the outside of the stamping die, occupying a large external space and having low adjustment accuracy. To save space and improve stamping accuracy, it is necessary to develop a stripping device with a simple structure, high accuracy, and small space occupation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a limit adjustment device for stamping dies. The device is located inside the stamping die and can adjust the size of the product during stamping. After stamping, the product is ejected. It has a simple structure, high precision, and small space occupation.

[0005] Specifically, this utility model discloses a limiting adjustment device for stamping dies, used to enable rapid demolding of products. It includes an upper die base and a lower die plate. The upper die base moves up and down in a direction perpendicular to the horizontal plane. A stripper plate is provided below the upper die base. The stripper plate has an upper forming part. The lower die plate has a lower forming component that matches the upper forming part. The lower forming component also has adjustment components on both sides for fixing the product, and an upper abutment component at the bottom for ejecting the product. The adjustment components are rotatably connected to the lower forming component, and the upper abutment component is fixedly connected to the lower forming component.

[0006] By adopting the above scheme, while the upper forming part applies pressure to the product, the lower forming component can drive the adjustment components on the left and right sides to adjust the size of the product. The adjustment components can further fix the product and improve the stamping accuracy of the product. After stamping, the upper forming part disengages from the lower forming component, and the upper abutment component pushes the lower forming component to eject the product.

[0007] Furthermore, the upper forming part is slidably connected to the stripper plate, and the distance between the lower surface of the upper forming part and the lower surface of the stripper plate is adjusted by adjusting bolts.

[0008] By adopting the above scheme, the distance between the lower surface of the upper forming part and the lower surface of the stripper plate can be changed, thereby changing the downward movement distance of the lower forming block when the upper forming part is pressed down and the adjustment force of the adjustment component on the product.

[0009] Furthermore, the lower forming assembly includes an adjusting fixing seat and a lower forming block slidably connected to the adjusting fixing seat. The adjusting fixing seat is fixedly connected to the lower template, and the lower forming block is connected to the upper abutment assembly; wherein,

[0010] The inner sides of the adjustment fixing seat are also provided with movable grooves for accommodating the adjustment component, and the bottom of the left and right sides of the lower molding block are provided with first inclined surfaces for controlling the movement of the adjustment component.

[0011] By adopting the above scheme, the lower molding block is subjected to the action of the upper molding part and the upper abutment component, and moves up and down reciprocally in the adjustment fixing seat. The movable groove inside the adjustment fixing seat is used to accommodate the adjustment component. The setting of the first inclined surface facilitates cooperation with the adjustment component and controls its movement.

[0012] Furthermore, the side wall of the lower forming block is also provided with rollers to assist the movement of the lower forming block. The rollers include a first roller and a second roller. The first roller is provided on the left and right sides of the lower forming block and the second roller is provided on the front and rear sides of the lower forming block and is in rolling connection with the inner wall of the adjusting and fixing seat.

[0013] By adopting the above scheme, the rollers are set on the side wall of the lower forming block to assist the lower forming block in moving up and down in the adjusting fixed seat, thereby reducing the friction between the lower forming block and the adjusting fixed seat and preventing the lower forming block from getting stuck during movement.

[0014] Furthermore, the adjustment components are placed on both sides of the lower molding block, including a rotating shaft passing through the movable groove and an adjustment block rotatably connected to the rotating shaft. The two adjustment blocks are arranged symmetrically, and the top of the adjustment block is provided with an adjustment part that contacts the product, and the bottom is provided with a second inclined surface that matches the first inclined surface.

[0015] By adopting the above scheme, the adjusting block is placed on the rotating shaft, so that the adjusting block moves around the rotating shaft. The second inclined surface at the bottom of the adjusting block cooperates with the first inclined surface, thereby controlling the movement of the adjusting block and causing the top adjustment part to clamp the product and change its size.

[0016] Furthermore, the adjustment assembly also includes a reset spring, which is disposed in a mounting groove at the bottom of the adjustment block, with one end of the reset spring connected to the bottom wall of the mounting groove and the other end connected to the side wall of the movable groove.

[0017] By adopting the above scheme, the reset spring can automatically reset the adjusting block. When the upper molding part disengages from the lower molding assembly, the upper abutment assembly moves the lower molding block upward and no longer applies pressure to the adjusting block. At this time, the reset spring pushes out the adjusting block, causing the adjusting block to reset.

[0018] Furthermore, the upper abutment component includes an upper abutment spring and an upper abutment connecting rod. The upper abutment spring is disposed in the lower mold base below the lower template. One end of the upper abutment connecting rod is connected to the upper abutment spring, and the other end is connected to the bottom of the lower forming block. The upper abutment spring provides an upward support force for the lower forming block.

[0019] By adopting the above solution, when the upper molding part is separated from the lower molding assembly, no pressure is applied to the lower molding block. At this time, the upper abutment spring pushes the upper abutment linkage to move, thereby causing the lower molding block to move upward. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, this utility model discloses a limiting adjustment device for stamping dies, used to enable products to be quickly demolded. It includes an upper die base 1 and a lower die plate 4. The upper die base 1 moves up and down in a direction perpendicular to the horizontal plane. A stripper plate 2 is provided below the upper die base 1. The stripper plate 2 has an upper forming part 21. The lower die plate 4 has a lower forming component 41 that matches the upper forming part 21. The lower forming component 41 also has adjustment components 42 on both sides for fixing the product. The bottom has an upper abutment component 43 for ejecting the product. The adjustment components 42 are rotatably connected to the lower forming component 41. The upper abutment component 43 is fixedly connected to the lower forming component 41.

[0029] The upper forming part 21 of this utility model applies downward pressure to the product. During the downward pressing process, under the influence of the lower forming component 41, the adjustment components 42 on the left and right sides can be driven to adjust the size of the product. The adjustment components 42 can further fix the product and improve the stamping accuracy of the product. After the stamping is completed, the upper forming part 21 disengages from the lower forming component 41, and the upper abutment component 43 pushes the lower forming component 41 to push the product out.

[0030] Furthermore, the upper forming part 21 is slidably connected to the stripper plate 2, and the distance between the lower surface of the upper forming part 21 and the lower surface of the stripper plate 2 is adjusted by adjusting bolt 22. By changing the distance between the lower surface of the upper forming part 21 and the lower surface of the stripper plate 2, the downward movement distance of the lower forming block 413 when the upper forming part 21 is pressed down and the adjustment force of the adjusting component 42 on the product can be changed.

[0031] Among them, a stop plate 3 is provided between the upper mold base 1 and the stripper plate 2. The adjusting bolt 22 passes through the upper forming part 21 and is fixed on the stop plate 3, which improves the stability of the upper forming part 21.

[0032] In some embodiments of this utility model, the lower forming component 41 includes an adjusting fixing seat 411 and a lower forming block 413 slidably connected to the adjusting fixing seat 411. The adjusting fixing seat 411 is fixedly connected to the lower template 4, and the lower forming block 413 is connected to the upper abutment component 43. The adjusting fixing seat 411 has movable grooves 412 on both sides inside for accommodating the adjusting component 42, and the lower forming block 413 has first inclined surfaces 414 on the bottom of its left and right sides for controlling the movement of the adjusting component 42. During operation, the lower forming block 413 reciprocates up and down within the adjusting fixing seat 411 under the action of the upper forming part 21 and the upper abutment component 43. The movable grooves 412 inside the adjusting fixing seat 411 accommodate the adjusting component 42, and the first inclined surfaces 414 facilitate cooperation with the adjusting component 42 and control its movement.

[0033] In some embodiments of this utility model, to improve the smoothness of the movement of the lower molding block 413, the side wall of the lower molding block 413 is also provided with rollers to assist the movement of the lower molding block 413. The rollers include a first roller 415 and a second roller 416. The first roller 415 is located on the left and right sides of the lower molding block 413, and the second roller 416 is located on the front and rear sides of the lower molding block 413, and is in rolling connection with the inner wall of the adjusting fixing seat 411. The rollers located on the side wall of the lower molding block 413 assist the lower molding block 413 in moving up and down in the adjusting fixing seat 411, reducing the friction between the lower molding block 413 and the adjusting fixing seat 411, and preventing the lower molding block 413 from jamming during movement.

[0034] In some embodiments of this utility model, the adjusting component 42 is placed on both sides of the lower forming block 413, including a rotating shaft 421 passing through the movable groove 412 and an adjusting block 422 rotatably connected to the rotating shaft 421. The two adjusting blocks 422 are arranged symmetrically, and the top of the adjusting block 422 is provided with an adjusting part 423 that contacts the product, and the bottom is provided with a second inclined surface 424 that matches the first inclined surface 414. When the adjusting block 422 is placed on the rotating shaft 421, the adjusting block 422 moves around the rotating shaft 421. The second inclined surface 424 at the bottom of the adjusting block 422 cooperates with the first inclined surface 414, thereby controlling the movement of the adjusting block 422, so that the adjusting part 423 at the top clamps the product, clamps the product, and changes its size.

[0035] In addition, the adjusting assembly 42 also includes a return spring 425, which is located in the mounting groove 426 at the bottom of the adjusting block 422. One end of the return spring 425 is connected to the bottom wall of the mounting groove 426, and the other end is connected to the side wall of the movable groove 412. The return spring 425 allows the adjusting block 422 to automatically reset. When the upper molding part 21 disengages from the lower molding assembly 41, the upper abutment assembly 43 moves the lower molding block 413 upward, no longer applying pressure to the adjusting block 422. At this time, the return spring 425 pushes out the adjusting block 422, causing the adjusting block 422 to reset.

[0036] In some embodiments of this utility model, the upper abutment component 43 includes an upper abutment spring 431 and an upper abutment connecting rod 432. The upper abutment spring 431 is disposed in the lower mold base 5 below the lower template 4. One end of the upper abutment connecting rod 432 is connected to the upper abutment spring 431, and the other end is connected to the bottom of the lower molding block 413. The upper abutment spring 431 provides an upward support force for the lower molding block 413. When the upper molding part 21 disengages from the lower molding component 41, it no longer applies pressure to the lower molding block 413. At this time, the upper abutment spring 431 pushes the upper abutment connecting rod 432 to move, thereby causing the lower molding block 413 to move upward.

[0037] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
