Description

Technical Field

[0001] This application relates to the field of automotive parts technology, specifically to a bracket stamping die. Background Technology

[0002] A stamping die is a type of processing equipment used in stamping processes. It utilizes a die mounted on a press to apply pressure to material, causing it to separate or undergo plastic deformation, thereby obtaining parts of the desired shape and size. Its working principle is based on the fundamental principles of stamping. Through the specific shape and structure of the die, the material undergoes the desired deformation under pressure. For example, in automobile manufacturing, many metal parts such as body panels, doors, and brackets are processed using stamping dies. Generally, it consists of two parts: an upper die and a lower die.

[0003] However, in traditional bracket stamping dies, the movement of the bracket and the stamping process are often relatively independent. For example, the bracket might be placed in the die for stamping first, and then manually removed and moved to the next processing position, or a simpler mechanical device might be used for movement. However, it's difficult to achieve precise coordination with the stamping action. This makes it impossible to perform surface grooving and other stamping operations simultaneously during bracket movement, reducing processing efficiency and making it difficult to guarantee processing accuracy. Because the bracket's position may deviate during multiple manual interventions or inaccurate movements, affecting the stamping quality.

[0004] Therefore, it is necessary to provide a bracket stamping die to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0037] Please see Figures 1-7 The embodiments provided by this utility model are as follows:

[0038] like Figure 1 As shown, a bracket stamping die includes a fixed die assembly 1 and a moving die assembly 2 for stamping a bracket 5. The top surface of the fixed die assembly 1 is slidably connected to the moving die assembly 2. A pusher device 3 is fixedly installed on one side of the fixed die assembly 1. The pusher device 3 includes an intermittent motion mechanism, a transmission mechanism, and a pusher plate 311. The intermittent motion mechanism provides intermittent linear motion to the pusher plate 311 through the transmission mechanism. The pusher plate 311 is slidably connected between the fixed die assembly 1 and the moving die assembly 2.

[0039] The fixed mold assembly 1 and the moving mold assembly 2 work together to perform the stamping process of the bracket 5. The pusher device 3 provides intermittent push to move the bracket 5, and the guide device 4 guides the movement of the bracket 5. The moving mold assembly 2 slides on the fixed mold assembly 1 to realize the stamping action, so that the mold can perform the stamping process of the bracket 5 in an orderly manner. The movement of the bracket 5 and the stamping action are combined to improve the automation and efficiency of the processing.

[0040] Specifically, such as Figure 5 and Figure 6 As shown, the intermittent motion mechanism includes a drive motor 33, a rotating wheel 34, a rotating plate 35, a pawl 36, and a ratchet 37. A fixed plate 31 is fixedly installed on one side of the fixed mold assembly 1. A fixed frame 32 is fixedly connected to the top surface of the fixed plate 31. The drive motor 33 is fixedly installed on the bottom side wall of the fixed frame 32. The rotating wheel 34 is rotatably connected to the bottom of the fixed frame 32. One side of the rotating wheel 34 is a concave arc surface. The output shaft of the drive motor 33 is fixedly installed with the rotating shaft of the rotating wheel 34. The middle part of the rotating plate 35 is hinged to the side wall of the fixed frame 32. A pulley is rotatably installed at the bottom of the rotating plate 35. The pulley rolls on the surface of the rotating wheel 34. The other end of the rotating plate 35 is hinged to the pawl 36. The ratchet 37 is rotatably connected to the top of the fixed frame 32. The pawl 36 slides against the tooth groove on the side wall of the ratchet 37.

[0041] In use, the drive motor 33 starts, driving the rotating wheel 34 to rotate. The concave arc surface of the rotating wheel 34 causes the pulley at the bottom of the rotating plate 35 to roll, thereby causing the rotating plate 35 to rotate around the hinge point with the side wall of the fixed frame 32. The pawl 36 at the other end of the rotating plate 35 pushes the ratchet 37 to rotate one tooth pitch, realizing intermittent rotation. This converts the continuous rotation of the motor into the intermittent rotation of the ratchet 37, providing intermittent power input for the subsequent transmission mechanism.

[0042] The transmission mechanism includes a bevel gear transmission mechanism 38, a moving block 39, a threaded rod 313, and a limiting rod 310. The rotating shaft of the ratchet 37 is keyed to the input end of the bevel gear transmission mechanism 38. The output end of the bevel gear transmission mechanism 38 is fixedly installed to one end of the threaded rod 313. A threaded groove 312 is provided through the side wall of the moving block 39. The side wall of the threaded rod 313 is threadedly connected to the threaded groove 312. Sliding holes 314 are provided at both ends of the moving block 39. The side wall of the limiting rod 310 is slidably connected in the sliding hole 314. One end of the limiting rod 310 is fixedly installed on the side wall of the vertical plate 315. A limiting plate is fixedly installed at the other end of the limiting rod 310. The vertical plate 315 is vertically fixed to the top surface of the fixed plate 31. The end face of the moving block 39 is fixedly connected to the pusher plate 311.

[0043] When the ratchet 37 rotates, its shaft drives the input end of the bevel gear transmission mechanism 38 to rotate via a key connection. The bevel gear transmission mechanism 38 transmits power to the threaded rod 313 to make it rotate. The threaded rod 313 is threadedly connected to the threaded groove 312 on the moving block 39, so that the moving block 39 moves linearly along the threaded rod 313 when the threaded rod 313 rotates. The limit rod 310 restricts the direction of movement of the moving block 39 to ensure its linear movement. The moving block 39 drives the pusher plate 311 to move, converting the intermittent rotation of the ratchet 37 into the intermittent linear movement of the pusher plate 311, and transmitting power from the intermittent motion mechanism to the pusher plate 311 to achieve the pushing effect on the bracket 5.

[0044] like Figure 7 As shown, a material guiding device 4 is fixedly installed on the other side of the fixed mold assembly 1. The material guiding device 4 includes a base plate 41, a support column 42, a support frame 43, and a sliding roller 44. The base plate 41 is fixedly installed on the other side wall of the fixed mold assembly 1. The top surface of the base plate 41 is fixedly installed to the support frame 43 through the support column 42. The two ends of the multiple sliding rollers 44 are rotatably connected on the inner side wall of the support frame 43 through bearings.

[0045] The support 5 moves to the guide device 4 under the push of the pusher plate 311. The support 5 contacts the sliding roller 44. Under the rolling action of the sliding roller 44, the support 5 moves on the top surface of the support frame 43, so that the support 5 maintains a stable motion trajectory during the movement, reduces the damage to the surface of the support 5 caused by friction and other factors, improves the processing quality of the support 5, and also improves the overall working efficiency of the mold.

[0046] It is worth noting that, such as Figure 4 As shown, the fixed mold assembly 1 includes a lower mold plate 11, a positioning cylinder 12, a forming platform 13, a guide post 14, and a waste trough 15. The positioning cylinder 12 is fixedly installed at the four corners of the top surface of the lower mold plate 11. The forming platform 13 is set on the top surface of the lower mold plate 11. The top surface of the forming platform 13 is provided with a channel for the support 5 to pass through. The guide post 14 is fixedly installed on the top surface of the forming platform 13 located on both sides of the channel. The side wall of the guide post 14 is provided with a sliding groove. The processing position on the top surface of the forming platform 13 is provided with a waste trough 15, and the waste trough 15 extends through to the bottom surface of the lower mold plate 11. A limit post is fixedly installed on one side of the top surface of the lower mold plate 11. The limit post abuts against the bottom surface of the upper mold plate 21.

[0047] The support 5 is placed in the channel on the forming table 13 through the slide groove on the guide column 14. The positioning rod 22 of the moving mold assembly 2 is inserted into the positioning cylinder 12 to realize the positioning of the moving mold assembly 2 and the fixed mold assembly 1. The stamping part 25 descends under the action of the moving mold assembly 2 to stamp the support 5. The waste generated by stamping is discharged through the waste groove 15, which provides positioning and support for the support 5, determines the processing position of the support 5, and provides a channel for the discharge of waste, ensuring the smooth progress of the stamping process.

[0048] like Figure 2 and Figure 3 As shown, the moving mold assembly 2 includes an upper template 21, positioning rods 22, mounting plate 23, movable plate 24, and springs 26. Positioning rods 22 are fixedly installed at the four corners of the bottom surface of the upper template 21, and the bottom of the positioning rods 22 are slidably connected to the inside of the positioning cylinder 12. Mounting plate 23 is fixedly installed on the bottom surface of the upper template 21, and sliding rods are fixedly installed at the four corners of the bottom surface of the mounting plate 23. Limiting holes are opened at the four corners of the movable plate 24, and the sliding rods are slidably connected in the limiting holes. Multiple equally spaced mounting holes are opened on the side of the movable plate 24 opposite to the mounting plate 23, and springs 26 are installed in the mounting holes. A clearance groove is opened through the bottom surface of the movable plate 24. A stamping part 25 for stamping the bracket 5 is fixedly installed on the bottom surface of the mounting plate 23. The stamping part 25 is slidably connected in the clearance groove, and the bottom of the stamping part 25 is slidably connected in the scrap groove 15.

[0049] The upper template 21 descends under pressure, and the positioning rod 22 is inserted into the positioning cylinder 12 to achieve positioning. The mounting plate 23 drives the stamping part 25 to descend. The stamping part 25 passes through the relief groove of the movable plate 24 to stamp the bracket 5. The spring 26 plays a role in buffering and resetting during the stamping process. After the stamping is completed, the upper template 21 rises, and the spring 26 resets the movable plate 24 to realize the stamping action on the bracket 5. Through the buffering and resetting function of the spring 26, the stability and safety of the stamping process are ensured. At the same time, the design of the movable plate 24 can protect the stamping part 25 and the bracket 5 to a certain extent.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
