Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a stamping die based on contact correction. Background Technology
[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces of the desired shape and size. Stamping and forging are both plastic processing techniques and are collectively referred to as forging and pressing. This processing technology is fast and low-cost, and is widely used in the field of machining.
[0003] Currently, existing stamping dies are prone to vibration due to the collision during the mold closing process of the upper and lower dies. Excessive vibration can easily lead to misalignment when the upper and lower dies close, thus affecting the stamping quality of the product. To address this, we propose a stamping die based on contact correction. Utility Model Content
[0004] The purpose of this invention is to provide a stamping die based on contact correction, which has the advantages of contact correction and good processing quality. It solves the problem that existing stamping dies are prone to vibration due to the collision during the mold closing process of the upper and lower dies. Excessive vibration can easily lead to misalignment when the upper and lower dies close, thus affecting the stamping quality of the product.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping die based on contact correction, comprising a base, with uprights fixedly connected to both the left and right ends of the top of the base, a movable plate slidably connected to the upper end of the outer surface of the uprights, an upper die body fixedly installed at the middle end of the bottom of the movable plate, a fixed frame fixedly connected to the lower end of the outer surface of the upper die body, a frame-shaped correction block fixedly connected to the bottom of the fixed frame, correction balls provided on both the inner and outer sides of the frame-shaped correction block, a lower die body fixedly installed at the middle end of the top of the base, and a correction seat adapted to the frame-shaped correction block fixedly installed at the upper end of the outer surface of the lower die body.
[0006] Preferably, there are multiple corrective balls, and the distance between any two adjacent corrective balls is equal.
[0007] Preferably, the longitudinal section of the frame-shaped correction block is an isosceles triangle.
[0008] Preferably, a second vibration-damping pad is bonded to the outer end face of the bottom of the frame-shaped correction block, buffer springs are fixedly connected to both the left and right ends of the top of the base, a bearing plate is fixedly connected to the top of the buffer springs, a first vibration-damping pad is bonded to the top of the bearing plate, a guide rod that slides on the inner surface of the base is fixedly connected to the middle of the bottom of the bearing plate, and a push rod is fixedly connected to the bottom of the guide rod.
[0009] Preferably, a fixing plate is fixedly connected to both the left and right ends of the bottom of the base cavity, and a guide rod is fixedly connected to both the front and rear sides of the fixing plate. A U-shaped seat is slidably connected to the end of the guide rod away from the fixing plate. A return spring sleeved on the outside of the guide rod is fixedly connected between the U-shaped seat and the fixing plate. A guide block with an isosceles triangle longitudinal section is fixedly connected to both the front and rear sides of the inner wall of the U-shaped seat.
[0010] Preferably, guide grooves are provided at both the left and right ends of the top of the base, and support plates that slide in the guide grooves are fixedly connected at both the front and rear ends of the top of the U-shaped base. The height of the top of the support plate is the same as the height of the top of the lower mold body, and a U-shaped correction plate is fixedly connected to the top of the support plate.
[0011] Preferably, guide balls are provided at both the front and rear ends of the top and bottom of the U-shaped seat.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. By setting up a frame-shaped straightening block and a straightening seat, this utility model enables the frame-shaped straightening block to enter the straightening seat in advance when the upper mold body moves downward and closes with the lower mold body. With the assistance of the guiding and positioning of the straightening ball, the straightening capability of this stamping die is realized during mold closing, thus avoiding the situation where vibration causes misalignment when the upper mold body and the lower mold body close, thereby affecting the stamping quality of the product.
[0014] 2. This utility model, through the setting of a second and a first vibration-damping rubber pad, ensures that when the upper mold body drives the fixed frame to move downward, the second and first vibration-damping rubber pads make contact first, thus providing vibration-damping contact capability. Through the setting of a buffer spring and a guide rod, the continuously downward-moving upper mold body and fixed frame will drive the bearing plate, guide rod, and push rod downward, compressing the buffer spring. This provides collision buffering capability for the contact and mold closing between the upper and lower mold bodies, reducing the generation of collision vibration force. Through the setting of the fixed plate, guide rod, return spring, guide block, and U-shaped seat, when the push rod moves downward... Influenced by the guide block and guide rod with an isosceles triangle longitudinal section, the two U-shaped seats can be pushed closer to each other and compress the return spring. After the push rod passes the guide block with an isosceles triangle longitudinal section, the compressed return spring can push the two U-shaped seats to reset each other. During the left and right movement of the two U-shaped seats, the U-shaped straightening plate will move synchronously. This enables the U-shaped straightening plate to clamp and straighten the workpiece placed on the top of the lower mold body in one go before the frame-shaped straightening block enters the straightening seat and contacts the upper and lower mold bodies to close the mold. This ensures the processing quality of the workpiece when the upper and lower mold bodies contact and close the mold. Attached Figure Description

[0024] Example 1
[0025] Please see Figures 1-4As shown, this utility model provides a technical solution: a stamping die based on contact correction, including a base 1, with uprights 4 fixedly connected to the left and right ends of the top of the base 1, a movable plate 9 slidably connected to the upper end of the outer surface of the uprights 4, an upper die body 14 fixedly installed at the middle end of the bottom of the movable plate 9, a fixed frame 11 fixedly connected to the lower end of the outer surface of the upper die body 14, a frame-shaped correction block 12 fixedly connected to the bottom of the fixed frame 11, the longitudinal section of the frame-shaped correction block 12 being an isosceles triangle, and correction balls 15 being provided on both the inner and outer sides of the frame-shaped correction block 12, the number of correction balls 15 being multiple, and the distance between two adjacent correction balls 15 being equal, a lower die body 6 fixedly installed at the middle end of the top of the base 1, and a correction seat 8 adapted to the frame-shaped correction block 12 fixedly installed at the upper end of the outer surface of the lower die body 6.
[0026] This technical solution: By setting up the frame-shaped correction block 12 and the correction seat 8, when the upper mold body 14 moves downward and closes with the lower mold body 6, the frame-shaped correction block 12 can enter the correction seat 8 in advance. With the assistance of the guiding and positioning of the correction ball 15, the correction capability of this stamping die is realized when it closes, so as to avoid the situation where vibration causes misalignment between the upper mold body 14 and the lower mold body 6 when they close, which would affect the stamping quality of the product.
[0027] Example 2
[0028] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a second vibration-damping pad 22 is bonded to the outer end face of the bottom of the frame-shaped correction block 12. Buffer springs 2 are fixedly connected to both ends of the top of the base 1. A bearing plate 10 is fixedly connected to the top of the buffer springs 2. A first vibration-damping pad 21 is bonded to the top of the bearing plate 10. A first guide rod 3, sliding on the inner surface of the base 1, is fixedly connected to the middle of the bottom of the bearing plate 10. A push rod 16 is fixedly connected to the bottom of the first guide rod 3. Fixing plates 18 are fixedly connected to both ends of the bottom of the inner cavity of the base 1. Second guide rods 19 are fixedly connected to both the front and rear sides of the fixing plate 18. A U-shaped seat 17 is slidably connected to the end of the outer surface of the rod 19 away from the fixed plate 18. A return spring 24 sleeved on the outside of the second guide rod 19 is fixedly connected between the U-shaped seat 17 and the fixed plate 18. Guide blocks 20 with an isosceles triangle longitudinal section are fixedly connected to both the front and rear sides of the inner wall of the U-shaped seat 17. Guide grooves 5 are opened at both the left and right ends of the top of the base 1. Support plates 7 that slide in the guide grooves 5 are fixedly connected to both the front and rear ends of the top of the U-shaped seat 17. The height of the top of the support plate 7 is the same as the height of the top of the lower mold body 6. A U-shaped straightening plate 13 is fixedly connected to the top of the support plate 7.
[0029] This technical solution: By setting the second vibration-damping rubber pad 22 and the first vibration-damping rubber pad 21, when the upper mold body 14 drives the fixed frame 11 to move downward, the second vibration-damping rubber pad 22 and the first vibration-damping rubber pad 21 will make contact first, thus achieving the ability of vibration-damping contact. By setting the buffer spring 2 and the first guide rod 3, after the second vibration-damping rubber pad 22 and the first vibration-damping rubber pad 21 make contact, the continuously moving upper mold body 14 and the fixed frame 11 will drive the bearing plate 10, the first guide rod 3 and the push rod 16 to move downward, and compress the buffer spring 2, thus achieving the ability of collision buffering for the contact and mold closing of the upper mold body 14 and the lower mold body 6, reducing the generation of collision vibration force. By setting the fixed plate 18, the second guide rod 19, the return spring 24, the guide block 20 and the U-shaped seat 17, when the push rod 16 moves downward, it is guided by the guide block with a longitudinal section of an isosceles triangle. Influenced by the second guide rod 19, the two U-shaped seats 17 can be pushed closer to each other and compress the return spring 24. After the push rod 16 passes the guide block 20 with an isosceles triangle longitudinal section, the compressed return spring 24 can push the two U-shaped seats 17 to reset each other. During the left and right movement of the two U-shaped seats 17, the U-shaped straightening plate 13 will move synchronously. This enables the U-shaped straightening plate 13 to clamp and straighten the workpiece placed on the top of the lower mold body 6 before the frame straightening block 12 enters the straightening seat 8 and contacts the upper mold body 14 and the lower mold body 6 to close the mold. This ensures the processing quality of the workpiece when the upper mold body 14 contacts the lower mold body 6 to close the mold. When the upper mold body 14 is reset, the reset force of the buffer spring 2 can force the return spring 24 to deform again and guide the push rod 16 to move to the top of the guide block 20 to reset.
[0030] Example 3
[0031] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, guide balls 23 are provided at both the front and rear ends of the top and bottom of the U-shaped seat 17.
[0032] This technical solution effectively reduces the resistance during the movement of the U-shaped seat 17 by setting the guide ball 23.
[0033] Working principle: The workpiece to be processed is placed on top of the lower mold body 6. Then, when the movable plate 9 drives the upper mold body 14 to move downward, the frame-shaped straightening block 12 can enter the straightening seat 8 in advance. With the assistance of the guiding and positioning of the straightening ball 15, the upper mold body 14 and the lower mold body 6 are accurately closed. When the upper mold body 14 drives the fixed frame 11 to move downward, the second vibration isolation pad 22 and the first vibration isolation pad 21 first come into contact, which will drive the bearing plate 10, the first guide rod 3 and the push rod 16 to move downward, compressing the buffer spring 2. When the push rod 16 moves downward, it is subjected to the action of the isosceles triangle in longitudinal section. The guide block 20 and the second guide rod 19 influence each other, which can push the two U-shaped seats 17 closer to each other and compress the return spring 24. After the push rod 16 passes the guide block 20 with an isosceles triangle longitudinal section, the compressed return spring 24 can push the two U-shaped seats 17 to reset each other. During the left and right movement of the two U-shaped seats 17, the U-shaped straightening plate 13 will move synchronously, thereby enabling the U-shaped straightening plate 13 to clamp and straighten the workpiece placed on the top of the lower mold body 6 in one operation before the frame straightening block 12 enters the straightening seat 8 and contacts the upper mold body 14 and the lower mold body 6 to close the mold.
