Description

Technical Field

[0001] This utility model belongs to the field of mold positioning technology, and specifically relates to a stamping mold positioning device. Background Technology

[0002] Existing stamping machines require positioning of the stamping dies during use to ensure the stability of the dies and prevent positional shifts during operation.

[0003] Currently, Chinese utility model patent CN220970543U discloses a stamping die positioning device for a stamping press. This device, through an L-shaped clamping mechanism, allows adjacent clamping members to form an open "mouth"-shaped limiting space, thereby clamping the die on all four sides (front and back) to improve its stability. However, because the clamping process requires adjusting and aligning each side individually, it cannot quickly clamp the stamping die, making operation cumbersome, resulting in low positioning efficiency and making it impractical for real-world use. Utility Model Content

[0004] The purpose of this utility model is to provide a stamping die positioning device, which has the advantages of facilitating quick four-sided clamping and positioning of the stamping die and enabling fine adjustment of the stamping die position.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stamping die positioning device, including a positioning platform, positioning clamps symmetrically arranged on the four sides of the top of the positioning platform, threaded shafts rotatably connected to the positioning platform at the bottom of the four positioning clamps, first bevel gears bolted to the ends of the four threaded shafts that are close to each other, second bevel gears respectively meshing with the four first bevel gears rotatably connected inside the positioning platform, and threaded bushings slidably connected to the positioning platform threadedly sleeved on the surface of the four threaded shafts.

[0006] The above technical solution utilizes the meshing of the first and second bevel gears to synchronously drive the four threaded shafts inside the positioning platform to rotate. This allows the four positioning clamping plates to quickly clamp and position the stamping die on all four sides, eliminating the need for individual adjustments and simplifying operation. Each of the four positioning clamping plates can extend and retract at one end of the fixed block, allowing for adjustment to accommodate the different concave and convex shapes of the stamping die and ensuring a stable fit. Furthermore, the clamped and positioned die can be manually offset in four different directions, enabling fine-tuning based on the punch position. This adaptability to different stamping machines enhances the practicality of the positioning device.

[0007] The present invention is further configured such that: each of the four positioning clamps is welded with a telescopic sleeve on the side away from each other; the telescopic sleeve is provided with a positioning rod welded to the positioning clamp; the surface of the positioning rod is slidably sleeved with a fixing block slidably connected to the telescopic sleeve; the bottom of the fixing block is welded through the top of the threaded bushing; and the top of the telescopic sleeve away from the positioning clamp is threadedly connected with a limiting bolt that engages with the fixing block.

[0008] By adopting the above technical solution, not only can the die be adjusted according to the different concave and convex shapes of its four sides to ensure a stable fit, but it can also be manually offset in four different directions, allowing for fine-tuning of the die based on the punch position.

[0009] The present invention is further configured such that a knob block, which is bolted to a threaded shaft, is rotatably connected through one side of the positioning platform.

[0010] The above technical solution facilitates the rotation of the threaded shaft by turning the knob block, thereby positioning and clamping the mold.

[0011] The present invention is further configured such that anti-slip pads are adhered to the sides of the four positioning clamps that are close to each other.

[0012] By adopting the above technical solution, friction is increased, thereby improving the stability of the positioning clamp in holding the positioning mold.

[0013] The present invention is further configured such that: a support plate is welded to the bottom of the threaded bushing, and a rolling ball that is rotatably connected to the positioning platform is slidably connected inside the support plate.

[0014] The above technical solution supports the forward and backward sliding of the threaded bushing, thereby improving the stability of the thread engagement between the threaded bushing and the threaded shaft.

[0015] The present invention is further configured such that bolt plates are welded to all four sides of the bottom of the positioning platform.

[0016] By adopting the above technical solution, the positioning platform can be easily bolted to the stamping equipment platform by passing the bolt through the interior of the bolt plate.

[0017] The present invention is further configured such that: a limiting block that is slidably connected to the fixing block is welded to one end of the positioning rod away from the positioning clamp.

[0018] By adopting the above technical solution, the sliding distance of the fixing block on the surface of the positioning rod is limited to prevent the fixing block from sliding out of the interior of the telescopic sleeve.

[0019] The present invention is further configured such that a scale is marked on one side of the surface of the fixing block.

[0020] By adopting the above technical solution, the sliding distance of the telescopic sleeve on the surface of the fixed block can be adjusted by observing the scale, which facilitates precise control of the movement distance.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. The four threaded shafts inside the positioning platform are synchronously driven to rotate by the meshing of the first and second bevel gears. This allows the four positioning clamping plates to come close together to quickly clamp and position the stamping die on all four sides, eliminating the need for adjustment one side at a time, thus simplifying operation.

[0023] 2. The four positioning clamps can extend and retract at one end of the fixed block, allowing adjustment to accommodate different concave and convex shapes on the four sides of the stamping die, ensuring a stable fit. Furthermore, the clamped and positioned die can be manually shifted in four different directions, enabling fine-tuning based on the punch position. This facilitates adaptation to different stamping machines and enhances the practicality of the positioning device. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] refer to Figure 1 , Figure 2A stamping die positioning device includes a positioning platform 1. Positioning clamps 6 are symmetrically arranged on the four sides of the top of the positioning platform 1. Each of the four positioning clamps 6 has a threaded shaft 2 rotatably connected to the bottom of the positioning platform 1. A first bevel gear 3 is bolted to one end of each of the four threaded shafts 2 that is close to each other. Second bevel gears 4, respectively meshing with the four first bevel gears 3, are rotatably connected inside the positioning platform 1. Threaded bushings 5, which are slidably connected to the positioning platform 1, are threaded onto the surfaces of the four threaded shafts 2. The meshing of the first bevel gears 3 and the second bevel gears 4 synchronously drives the four threaded shafts 2 inside the positioning platform 1 to rotate. This allows the four positioning clamps 6 to quickly clamp and position the stamping die on all four sides without the need for individual adjustment, facilitating operation.

[0031] refer to Figure 1 A knob block 11, bolted to the threaded shaft 2, is rotatably connected to one side of the positioning platform 1. This allows the threaded shaft 2 to be rotated by turning the knob block 11, thereby positioning and clamping the mold.

[0032] refer to Figure 1 , Figure 2 Anti-slip pads 13 are glued to the sides of the four positioning clamps 6 that are close to each other. This increases friction and improves the stability of the positioning clamps 6 in holding the positioning mold.

[0033] refer to Figure 2 A support plate 14 is welded to the bottom of the threaded bushing 5. A ball bearing 15, which is rotatably connected to the positioning platform 1, is slidably connected to the inside of the support plate 14. This supports the forward and backward sliding of the threaded bushing 5, thereby improving the stability of the thread engagement between the threaded bushing 5 and the threaded shaft 2.

[0034] refer to Figure 1 , Figure 2 The positioning platform 1 has bolt plates 12 welded to all four sides of its bottom. By passing bolts through the bolt plates 12, the positioning platform 1 can be easily bolted to the stamping equipment platform.

[0035] Brief description of the operation: By opening the threaded shaft 2 on one side of the rotation, the threaded shaft 2 drives the first bevel gear 3 and the second bevel gear 4 to mesh, thereby synchronously driving the four threaded shafts 2 inside the positioning platform 1 to rotate. Then, the threaded shaft 2 engages with the threaded bushing 5, causing the four threaded bushings 5 ​​to slide relative to each other inside the positioning platform 1. This allows the four positioning clamping plates 6 to move closer or further apart. As the four positioning clamping plates 6 move closer together, the stamping die can be clamped and positioned on all four sides simultaneously.

[0036] Example 2:

[0037] refer to Figure 1 , Figure 2 , Figure 3 A stamping die positioning device includes four positioning clamping plates 6, each with a telescopic sleeve 7 welded to one side away from the others. Inside each telescopic sleeve 7 is a positioning rod 10 welded to the positioning clamping plates 6. A fixing block 8, slidably connected to the telescopic sleeve 7, slides onto the surface of the positioning rod 10. The bottom of the fixing block 8 is welded to the top of a threaded bushing 5. A limiting bolt 9, threadedly connected to the fixing block 8, is threaded through the top of the telescopic sleeve 7 on the side away from the positioning clamping plates 6. The four positioning clamping plates 6 can telescopically move back and forth at one end of the fixing block 8, allowing adjustment to accommodate different concave and convex shapes on the four sides of the stamping die, ensuring a stable fit. Furthermore, the clamped and positioned die can be manually offset in four different directions, allowing for fine-tuning of the stamping die according to the punch position, facilitating adaptation to different stamping machines and improving the practicality of the positioning device.

[0038] refer to Figure 3 A limiting block 16, which is slidably connected to the fixing block 8, is welded to the end of the positioning rod 10 away from the positioning clamp 6. This limits the sliding distance of the fixing block 8 on the surface of the positioning rod 10, preventing the fixing block 8 from sliding out of the telescopic sleeve 7.

[0039] refer to Figure 1 , Figure 2 A scale 17 is marked on one side of the surface of the fixed block 8. The sliding distance of the telescopic sleeve 7 on the surface of the fixed block 8 can be adjusted by observing the scale 17, which facilitates precise control of the movement distance.

[0040] Brief description of the usage process: By rotating the limiting bolt 9 and engaging the threaded connection of the telescopic sleeve 7, the limiting bolt 9 is released from the fixed block 8. This allows the telescopic sleeve 7 and the positioning rod 10 to slide on the surface and inside of the fixed block 8, respectively. This causes the four positioning clamps 6 to extend and retract on the side of the fixed block 8 where they are close to each other. The limiting bolt 9 is then reversed to maintain the position. Furthermore, the positioning clamps 6 can be adjusted according to the different concave and convex shapes of the four sides of the stamping die, ensuring a stable fit between the four positioning clamps 6 and the die surface. Simultaneously, when one positioning clamp 6 slides forward or backward, the opposite positioning clamp 6 slides in the opposite direction. This allows the clamped and positioned die to be manually offset in four different directions, enabling fine-tuning of the stamping die according to the punch position, facilitating adaptation to different stamping machines.
