Description

Technical Field

[0001] This utility model relates to the field of high-precision small device processing technology, specifically a corner stamping die adapted to high-precision small device products. Background Technology

[0002] In today's industrial production sector, especially in industries such as electronics, medical devices, and precision instruments, the demand for high-precision small components is experiencing explosive growth. These small components typically have complex shapes and structures, including a large number of corner features. The forming quality of the corners directly affects the overall performance and reliability of the product, thus requiring the use of corner stamping dies.

[0003] Existing corner stamping dies have certain drawbacks in use. When making corners, the small size of the product makes positioning inconvenient, and the uneven stress during bending leads to unstable dimensions and inconsistent product quality after bending. Furthermore, the processing efficiency is very low. To solve these problems, a corner structure and its forming die disclosed in existing technology (application number CN202420089359.U, publication date 2024-10-15) can be referenced. This forming die involves removing the positioning cover and placing the stamped sheet metal onto the top of the positioning shaft. On the surface, the positioning cover is movably sleeved on the top of the positioning shaft. The moving mold is driven downward by the stamping machine. At this time, the conical groove cooperates with the conical fixed mold to stamp the process connecting ring and the corner structure body into an arc shape. Then, the positioning cover is removed, the stamped corner structure body is removed, and multiple corner structure bodies are cut off from the process connecting ring. Since the product is a symmetrical part, the force is evenly balanced. The force on the four sides of the product is stable during the processing, which is convenient for processing. At the same time, the quality of the formed parts is uniform, and multiple sets of corner structure bodies can be processed at one time, which improves processing efficiency.

[0004] Although the above-mentioned device can achieve the purpose of positioning through the setting of positioning slots, it still has certain shortcomings in actual use. For example, when working, it not only needs the cooperation of a hydraulic press, but also needs a drive motor to achieve the bending process, which requires multiple driving forces, making the operation relatively cumbersome.

[0005] Therefore, we proposed a corner stamping die suitable for high-precision small components, which can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a corner stamping die suitable for high-precision small components, so as to solve the problem mentioned in the background art that the current corner stamping dies on the market not only need to use the cooperation of a hydraulic press when working, but also need to drive a motor to achieve the bending process, thus requiring multiple driving forces and making the operation cumbersome.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a corner stamping die adapted to high-precision small device products, including an upper moving die and a lower fixed die. The top of the upper moving die and the bottom of the lower fixed die are connected at the four corners by guide sleeves. Two sets of force-bearing columns are fixed at the bottom front end of the upper moving die. The position directly below the force-bearing columns corresponds to the top position of the driving component. The driving component moves downward to bend the bending plates set inside the fixed sleeves on both sides. Several sets of limiting holes are opened on the front surface of the bending plates.

[0008] As a preferred technical solution of this application, the bending plate has a rotation range of 0-90 degrees, and the bottom outer side of the fixed sleeve is fixed to the inner side of the upper moving mold. The bending plate is made of high-strength alloy steel and is nitrided to improve surface hardness and wear resistance, thereby enabling the bending of the workpiece.

[0009] As a preferred technical solution of this application, the driving component includes a fixed block slidably disposed inside the upper moving mold. The bottom position of the fixed block is connected to the inner side of the upper moving mold through a guide sleeve. A mating rack is fixed to one side of the fixed block. The outer side of the mating rack is meshed with one side of a connecting gear. One side of the connecting gear is meshed with one side of a connecting gear. One side of the connecting gear is meshed with the mating gear. The mating gear is meshed below the rotating gear rod. The outer end of the mating gear is rotatably disposed inside the fixed sleeve.

[0010] As a preferred technical solution of this application, the mating rack, connecting gear, connecting gear, mating gear, and rotating gear rod are all rotatably connected to the interior of the upper moving mold, which allows the mating rack, connecting gear, connecting gear, mating gear, and rotating gear rod to rotate stably inside the upper moving mold.

[0011] As a preferred technical solution of this application, a spring is provided inside the guide sleeve, and the end of the rotating gear rod is fixedly connected to the end of the bending plate.

[0012] A corner stamping die adapted for high-precision small device products is disclosed, and the product processed by the corner stamping die is also disclosed. The outer side of the limiting hole is embedded into the outer side of the bottom of the protrusion, one end of the protrusion is fixed to one end of the processing strip, and the end of the processing strip is fixed to one side of the processed part.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This corner stamping die, adapted for high-precision small components, is equipped with a bending plate. Several sets of limiting holes are provided on the surface of the bending plate, allowing the limiting holes to correspond with the protrusions of the processing strip. This enables subsequent bending processing of the upper moving die. Furthermore, through the provided driving component, the bending plate bends the processing strip when the force column presses against the driving component, thus achieving bending processing through a linkage mechanism. Specific details are as follows:

[0014] 1. A driving component is provided. The pressure of the force column on the driving component causes the fixed block to drive the mating rack to rotate. Through the meshing of the connecting gear, connecting gear, mating gear and rotating gear rod, the rotating gear rod can drive the bending plate to bend. This makes the operation simpler and easier to use.

[0015] 2. A bending plate is provided, and several limiting holes are opened on the surface of the bending plate, so that one side of the limiting hole corresponds to the protrusion fixed by the processing strip, thereby facilitating positioning and bending processing, and bending processing is performed by the provided bending plate.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 The present invention provides the following technical solution:

[0025] Example 1

[0026] To facilitate the positioning and bending of workpiece 9, please refer to the attached document. Figure 1 -Appendix Figure 4 The system includes an upper moving mold 1 and a lower fixed mold 2. The top of the upper moving mold 1 and the bottom corners of the lower fixed mold 2 are connected by guide sleeves 3. Two sets of force-bearing columns 4 are fixed at the bottom front end of the upper moving mold 1. The position directly below the force-bearing columns 4 corresponds to the top position of the driving component 5. The driving component 5 moves downward to bend the bending plates 7 set inside the fixed sleeves 6 on both sides. Several sets of limiting holes 8 are opened on the front surface of the bending plates 7. The rotation range of the bending plates 7 is 0-90 degrees, and the bottom outer side of the fixed sleeves 6 is fixed to the inner side of the upper moving mold 1. The bending plates 7 are made of high-strength alloy steel and have undergone nitriding treatment to improve surface hardness and wear resistance.

[0027] First, the workpiece 9 to be processed is placed on the surface of the upper moving mold 1, and the processing strip 10 and the protrusion 11 on one side of the workpiece 9 are embedded into the interior of the limiting hole 8, thereby achieving the purpose of positioning. When bending is required, the top of the upper moving mold 1 is squeezed by the hydraulic press, so that the upper moving mold 1 is closed on the top of the lower fixed mold 2 through the guide sleeve 3, and the bottom position of the force column 4 corresponds to the bottom of the driving component 5, so that the driving component 5 can drive the bending plate 7 to bend through the linkage structure, thereby achieving the purpose of processing high-precision small parts.

[0028] Example 2

[0029] To address the issue that current corner stamping dies on the market require not only a hydraulic press but also a drive motor for bending, necessitating multiple driving forces and resulting in cumbersome operation, please refer to the attached document. Figure 1 -Appendix Figure 5 The driving component 5 includes a fixed block 51 slidably disposed inside the upper moving mold 1. The bottom position of the fixed block 51 is connected to the inner side of the upper moving mold 1 through a guide sleeve 52. A mating rack 53 is fixed to one side of the fixed block 51. The outer side of the mating rack 53 is meshed with one side of the connecting gear 54. One side of the connecting gear 54 is meshed with one side of the connecting gear 55. One side of the connecting gear 55 is meshed with the mating gear 56. The mating gear 56 is meshed below the rotating gear rod 57. The outer end of the rotating gear rod 57 is rotatably disposed inside the fixed sleeve 6. The mating rack 53, connecting gear 54, connecting gear 55, mating gear 56, and rotating gear rod 57 are all rotatably connected to the interior of the upper moving mold 1. A spring is disposed inside the guide sleeve 52, and the end of the rotating gear rod 57 is fixedly connected to the end of the bending plate 7.

[0030] When the bottom of the force-bearing column 4 presses against the top of the driving component 5, the driving component 5 can move the fixed block 51, thereby compressing the guide sleeve 52 at the bottom of the fixed block 51. The rack 53 on one side of the guide sleeve 52 will drive the meshing connecting gear 54 to rotate, so that the connecting gear 54, connecting gear 55, mating gear 56 and rotating gear rod 57 can all rotate inside the upper moving mold 1. Thus, the rotating gear rod 57 can drive the bending plate 7 to bend. With the above settings, not only can bending work be realized, but it is also simple to operate and more conducive to production.
