Description

Technical Field

[0001] This utility model relates to the field of stamping equipment, and in particular to a multi-station continuous stamping processing device for sheet metal brackets. Background Technology

[0002] Sheet metal brackets are support structures made through sheet metal processing techniques such as stamping, bending, and welding. They utilize the plasticity of metal sheets to achieve lightweight and high-strength support functions and are widely used in machinery, electronics, automotive, construction and other fields.

[0003] With the rapid development of industries such as automobile manufacturing, electronics, and machinery, the demand for sheet metal brackets has increased significantly. Traditional single-station stamping processing is inefficient and has scattered processes, making it difficult to meet the needs of mass production.

[0004] Chinese Patent Publication No. CN222873172U discloses a multi-station stamping die, relating to the structural technology of stamping dies for automotive chassis parts. It addresses the problem that stamping dies often cannot provide load-bearing and positioning for stamped parts, only performing single-unit stamping, and that stamped parts and production waste are difficult to recycle quickly. The die includes a die base, a load-bearing bracket, a stamping support frame, and a load-bearing top seat. Support side seats are installed on both sides of the top of the die base. The load-bearing bracket is installed on the top of the two sets of support side seats. The stamping support frame is slidably disposed on the side of the guide pillar. A stamping pillar is installed at the bottom of the load-bearing top seat, with a fixed support at one end of the stamping pillar and a stamping support at the bottom of the fixed support. The stamping support frame presses and fixes the stamped parts, allowing the stamping support block to cooperate with the stamping bottom groove to stamp the parts. A sliding support shaft, in conjunction with a lifting spring, can lift the stamping support frame to facilitate the push-pull recycling of the stamped parts after stamping.

[0005] Although the equipment described in the aforementioned documents can achieve multi-station stamping, it cannot replace the upper mold, making mold maintenance difficult and costly. Furthermore, it cannot adapt to diverse production needs, thus limiting the equipment's scope of application. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1, as Figure 1 As shown, a multi-station continuous stamping processing device for sheet metal brackets includes a base plate 1. A feeding assembly 2 is fixedly connected to the middle of the upper end of the base plate 1. A rotating assembly 3 is fixedly connected to the front side of the upper end of the base plate 1. A plurality of stamping assemblies 4 arranged in a linear array are fixedly connected to the upper side of the rotating assembly 3. A mold assembly 5 is installed on the lower side of each of the stamping assemblies 4. The mold assembly 5 is located on the upper side of the feeding assembly 2.

[0028] In this embodiment, the sheet metal bracket raw material is conveyed by the feeding component 2, and the feeding speed of the feeding component 2 is matched with the stamping speed and rhythm.

[0029] The feeding component 2 adopts existing technologies, such as roller feeders, clamp feeders, NC servo feeders, and robot feeding systems.

[0030] Roller feeders use the friction of upper and lower rollers to clamp the material strip. The motor drives the rollers to rotate and feeds the coil into the mold station according to the set length. They are often used for continuous feeding of coils and are suitable for stamping large batches of regular-shaped sheet metal parts.

[0031] The clamp feeder uses pneumatic or hydraulically driven grippers to periodically clamp the material strip forward. When the grippers clamp, the material is fed; when they release, the material returns to its original position. It works in conjunction with the cycle action of the stamping equipment and is suitable for feeding thin materials or high-precision materials. It is especially suitable for multi-station progressive die processing.

[0032] like Figure 2 As shown, the rotating assembly 3 includes a support 31 fixedly connected to the front side of the upper end of the base plate 1. Rotating plates 33 are rotatably connected to both sides of the inner surface of the support 31. A rotating shaft 32 is fixedly connected to one side of the two rotating plates 33. Gear 1 34 and gear 2 35 are rotatably connected to the right end of the support 31. Gear 1 34 and gear 2 35 mesh with each other. A motor 36 is fixedly connected to the right end of the support 31 through a bracket. The output end of the motor 36 passes through the bracket and is fixedly connected to gear 2 35 through a coupling. A partition 37 is fixedly connected to the lower side of the inner surface of the support 31. The right end of the rotating shaft 32 passes through the rotating plates 33 and the support 31 and is fixedly connected to gear 1 34.

[0033] Motor 36 drives gear 2 35 and gear 1 34 to rotate. Gear 1 34 drives rotating plate 33 to rotate. Rotating plate 33 drives rotating shaft 32 and cam 41 to reciprocate. While cam 41 reciprocates, it drives pressing block 42 to move up and down. When pressing block 42 moves, pressing block 42 guides it to ensure that pressing block 42 can move in the vertical direction.

[0034] like Figure 3 As shown, the stamping assembly 4 includes a cam 41 fixedly connected to the outer surface of the rotating shaft 32. A pressure block 42 is rotatably connected to the lower side of the cam 41. Guide rods 43 are fixedly connected to the four corners of the lower end of the pressure block 42. Four springs 44 are fixedly connected to the lower end of the pressure block 42. The four springs 44 are all sleeved on the outer surface of a guide rod 43 that is close to each other.

[0035] Specifically, the lower ends of several guide rods 43 all penetrate the partition 37.

[0036] When the pressure block 42 is pressed down, it and the partition plate 37 together compress the spring 44, which can play a buffering role during the stamping process.

[0037] Example 2: Based on Example 1, this example adds a mold component 5, which allows for quick installation and disassembly of the upper mold, facilitating replacement, shortening mold change time, and reducing downtime losses.

[0038] like Figure 4 and Figure 5 As shown, the mold assembly 5 includes a connecting part 51 located on the lower side of the partition plate 37. Support plates 52 are provided on both sides of the connecting part 51. A rod 53 is slidably connected to both support plates 52. A spring 54 is fixedly connected to the end of the two support plates 52 that is close to each other. The two springs 54 are sleeved on the outer surface of the rod 53. A rotating part 55 is threadedly connected to the right side of the outer surface of the rod 53. A locking block 56 is fixedly connected to the lower side of both support plates 52. Two guide rods 57 are fixedly connected to the side of the two support plates 52 that is close to each other. A module part 58 is movably connected to the lower side of the connecting part 51.

[0039] In this embodiment, the guide rod 43 drives the mold assembly 5 to move back and forth in the vertical direction, and the module part 58 is used for stamping. The module part 58 can be replaced according to the processing requirements.

[0040] Specifically, the connecting part 51 includes a plate 511 located on the lower side of the partition 37. A protrusion 512 is fixedly connected to the lower end of the plate 511. Grooves 513 are provided on both sides of the middle part of the plate 511. Sliding grooves 514 are provided at both ends of the plate 511. The upper end of the plate 511 is fixedly connected to four guide rods 43 that are close to each other.

[0041] Specifically, several springs 54 are all located in a groove 513 that is close to each other, and several guide rods 57 are slidably connected to the inner surface of a sliding groove 514 that is close to each other.

[0042] The second guide rod 57 can guide the sliding of the support plate 52, ensuring that the locking block 56 and the locking groove 583 can be accurately engaged.

[0043] like Figure 4As shown, the module 58 includes an upper mold 581 located on the lower side of the plate 511. A through groove 582 is provided in the middle of the upper end of the upper mold 581, and slots 583 are provided at both ends of the upper mold 581.

[0044] Furthermore, the shapes of several protrusions 512 and several through slots 582 are all adapted to each other, and the shapes of several locking blocks 56 and several locking slots 583 are all adapted to each other.

[0045] During implementation, first rotate the rotating part 55 to the right so that the rotating part 55 is away from the support plate 52, so that the two support plates 52 can slide on the outer surface of the rod 53. Slide the two support plates 52 in a direction away from each other, and drive the locking block 56 to slide out of the slot 583, so that the module part 58 can be removed from the device.

[0046] Place the through slot 582 of the new module 58 into the protrusion 512, then rotate the rotating member 55 to reduce the distance between the two support plates 52, push the locking block 56 into the through slot 582, and fix the upper mold 581 to the connecting part 51.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
