Description

Technical Field

[0001] This utility model relates to the field of anti-deformation support platform, and in particular to a thin plate punching anti-deformation support platform. Background Technology

[0002] Anti-deformation support platforms are support structures used in mold design to prevent deformation of workpieces or molds. They are commonly used in stamping, forming, and other processes, especially when processing thin or soft materials. They effectively prevent deformation caused by external forces or uneven material stress. Such anti-deformation support platforms for thin-plate punching are quite common in existing technologies.

[0003] Existing technologies, such as the utility model with publication number CN218835788U, disclose an adjustable-spacing thin-plate punching device. This patent employs a support platform, with a punching bracket fixed above the support platform. A punching cylinder is fixed to the top of the punching bracket, and a lower pressure block and a crossbar are connected to the lower end of the punching cylinder. An adjustable mechanism is distributed on the crossbar, comprising a tool holder, a punch, and a guide support block. The tool holder is fitted onto the crossbar, and a positioning rod is fixed below the punching bracket. The guide support block is fitted onto the positioning rod. This utility model features a uniquely designed adjustment mechanism that allows for easy movement on the crossbar and positioning rod, secured with screws. The C-shaped guide support block provides a dual function, improving the punching accuracy and stability. The entire device has a stable and uncomplicated structure, is very easy to operate, and is ideal for multi-hole processing of thin plates.

[0004] The inventors discovered in the prior art that when personnel replace the support platform body, they need to rely on tools such as hex wrenches. During the replacement process, the operator needs to repeatedly rotate the hex wrench to complete the disassembly and assembly of the support platform body. Because the operation process of this replacement method is very cumbersome and repetitive, it leads to the problem of low replacement efficiency for personnel. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the operation of replacing the support platform body using tools such as hex wrenches in the existing technology is cumbersome and repetitive, which leads to low personnel replacement efficiency. Therefore, a thin plate punched anti-deformation support platform is proposed.

[0006] To solve the above technical problems, this utility model provides a thin plate punching anti-deformation support platform, including: a lower die and a replacement structure. The support platform body is installed inside the lower die via the replacement structure. The support platform body has a lower die cutting edge inside. The lower die has a replacement structure inside, which includes two limiting grooves, a positioning groove, and two auxiliary grooves. Both limiting grooves are formed on the lower die, as are the positioning grooves and the two auxiliary grooves. The positioning groove communicates with the two limiting grooves. The groove and the auxiliary groove are interconnected. The inner wall of the limiting groove is slidably connected to a connecting plate. The positioning groove is slidably connected to the support platform body. The support platform body is fixedly connected to two connecting plates.

[0010] Preferably, a pull ring is fixedly connected to the arc surface of the auxiliary rod, and the cross-section of the pull ring is circular.

[0011] The effect achieved by the above components is that the pull ring allows personnel to easily move the auxiliary rod, thereby improving the ease of operation for personnel.

[0012] Preferably, the arc surface of the pull ring is fixedly connected to an anti-slip sleeve, and the cross-section of the anti-slip sleeve is a hollow circle.

[0013] The effect achieved by the above-mentioned components is that the anti-slip sleeve can increase the friction between the person's hand and the pull ring, and can prevent the person from slipping when moving the pull ring.

[0014] Preferably, two guide blocks are fixedly connected to the sides of the two card blocks that are close to each other, and the guide blocks are slidably connected to the card slots.

[0016] Preferably, the lower mold has an auxiliary structure inside, which includes two mounting slots and two connecting slots. The two mounting slots are both formed on the lower mold, and the two connecting slots are both formed on the support platform body. The two mounting slots are interconnected with the positioning slot. A moving block is slidably connected to the inner wall of the mounting slot. A limit rod is fixedly connected to the inner wall of the mounting slot. The limit rod is slidably connected to the moving block. A compression spring is sleeved on the arc surface of the limit rod. The two ends of the compression spring are fixedly connected to the moving block and the mounting slot, respectively. A connecting block is fixedly connected to the side of the two moving blocks that are close to each other. The connecting block is slidably connected to the connecting slot.

[0017] The effect achieved by the above components is that when personnel need to replace the support platform body by changing the structure, the two compression springs can rebound, causing the support platform body to move upward, thereby further improving the efficiency of personnel replacing the support platform body.

[0018] Preferably, a protective pad is fixedly connected to the upper surface of the connecting block, and the protective pad is slidably connected to the connecting groove.

[0019] The effect achieved by the above components is that the protective pad can protect the connecting block and prevent the upper surface of the connecting block from directly contacting the top wall of the connecting groove.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figure 1 and Figure 2 The present invention provides a thin plate punching anti-deformation support platform, comprising: a lower mold 1 and a replacement structure 3. The support platform body 2 is installed inside the lower mold 1 by means of the replacement structure 3. The support platform body 2 is provided with a lower mold cutting edge 5 inside. The lower mold 1 is provided with the replacement structure 3 inside. The lower mold 1 is provided with an auxiliary structure 4 inside.

[0031] In the embodiments of this utility model, please refer to Figure 3The replacement structure 3 includes two limiting grooves 302, a positioning groove 301, and two auxiliary grooves 305. Both limiting grooves 302 and the positioning groove 301 are formed on the lower mold 1. Both auxiliary grooves 305 are also formed on the lower mold 1. The positioning groove 301 communicates with the two limiting grooves 302, and the limiting groove 302 communicates with the auxiliary grooves 305. A connecting plate 304 is slidably connected to the inner wall of the limiting groove 302. The positioning groove 301 is slidably connected to the support platform body 2. The support platform body 2 is connected to the two auxiliary grooves 305. The connecting plate 304 is fixedly connected, and the inner wall of the connecting plate 304 is provided with a slot 306. The inner wall of the auxiliary slot 305 is slidably connected with a block 312. The two blocks 312 are fixedly connected to each other on the side away from each other. The auxiliary rod 309 is slidably connected to the lower mold 1 and to the auxiliary slot 305. The arc surface of the auxiliary rod 309 is fitted with a spring 308. The two ends of the spring 308 are fixedly connected to the block 312 and the auxiliary slot 305 respectively. The block 312 is slidably connected to the slot 306. When personnel need to replace the support platform body 2 with a lower die cutter 5 of a different size, they can first move the two auxiliary rods 309 to move the two locking blocks 312 away from the locking groove 306. Then, the personnel can move the support platform body 2 until the connecting plate 304 completely slides out of the inner wall of the limiting groove 302. This allows for quick and easy replacement of the support platform body 2, thus improving the efficiency of personnel replacement. Two limiting posts 307 are fixedly connected to the side of the two locking blocks 312 that are far apart from each other. The limiting posts 307 are slidably connected to the lower die 1. The limiting posts 307 can limit the locking blocks 312 and prevent them from being misaligned during sliding on the inner wall of the auxiliary groove 305. A pull ring 311 with a circular cross-section is fixedly connected to the arc surface of the auxiliary rod 309. The pull ring 311 facilitates the movement of the auxiliary rod 309, improving operational convenience. An anti-slip sleeve 310 is fixedly connected to the arc surface of the pull ring 311; the anti-slip sleeve 310 has a hollow circular cross-section. The anti-slip sleeve 310 increases the friction between the user's hand and the pull ring 311, preventing slippage during movement. Two guide blocks 303 are fixedly connected to the sides of the two locking blocks 312 that are close to each other. The guide blocks 303 are slidably connected to the locking groove 306. The guide blocks 303 guide the locking blocks 312, facilitating the sliding of the locking blocks 312 into the inner wall of the locking groove 306.

[0032] In the embodiments of this utility model, please refer to Figure 4The auxiliary structure 4 includes two mounting slots 41 and two connecting slots 46. The two mounting slots 41 are both opened on the lower mold 1, and the two connecting slots 46 are both opened on the support platform body 2. The two mounting slots 41 are interconnected with the positioning slot 301. The inner wall of the mounting slot 41 is slidably connected to a moving block 44. The inner wall of the mounting slot 41 is fixedly connected to a limiting rod 43. The limiting rod 43 is slidably connected to the moving block 44. The arc surface of the limiting rod 43 is fitted with a compression spring 42. The two ends of the compression spring 42 are fixedly connected to the moving block 44 and the mounting slot 41 respectively. The two moving blocks 44 are fixedly connected to each other on the side that is close to each other. The connecting block 45 is slidably connected to the connecting slot 46. When personnel need to replace the support platform body 2 by replacing structure 3, the two compression springs 42 can rebound, causing the support platform body 2 to move upward, thereby further improving the efficiency of personnel replacing the support platform body 2. A protective pad 47 is fixedly connected to the upper surface of the connecting block 45, and the protective pad 47 is slidably connected to the connecting groove 46. The protective pad 47 can protect the connecting block 45 and prevent the upper surface of the connecting block 45 from directly contacting the top wall of the connecting groove 46.

[0033] The working principle of the thin plate punching anti-deformation support platform provided by this utility model is as follows: When personnel need to punch holes in the thin plate, they first place the thin plate on the support platform, positioning it between the upper punching device and the support plate. Finally, the personnel activate the upper punching device to punch the thin plate. The upper surface of the support platform body 2 has a slightly protruding shape, which can counteract the stress generated during the punching process, thereby preventing deformation of the thin plate during punching. When punching holes of other sizes in the thin plate, the personnel can first use the anti-slip sleeve 310 to move the pull ring 311 away from the connecting plate 304. The anti-slip sleeve 310 increases the friction between the personnel's hand and the pull ring 311, preventing slippage during the movement of the pull ring 311. Then, the anti-slip sleeve 310 moves the pull ring 311 away from the connecting plate 304. The pull ring 311 facilitates the movement of the auxiliary rod 309. This improves the ease of operation for personnel. Then, the pull ring 311 drives the auxiliary rod 309 to move away from the connecting plate 304. The auxiliary rod 309 drives the locking block 312 to move away from the connecting plate 304. The locking block 312 drives the two limiting posts 307 and the two guide blocks 303 to move away from the connecting plate 304. The limiting posts 307 can limit the locking block 312 and prevent it from sliding on the inner wall of the auxiliary groove 305. During the process, misalignment occurs, and then the locking block 312 drives the spring 308 to rewind until the guide block 303 and the locking block 312 completely slide out of the inner wall of the slot 306. Then, the personnel move the support platform body 2, and the support platform body 2 drives the two connecting plates 304 to move upward until the connecting plates 304 completely slide out of the inner wall of the limiting groove 302. The guide block 303 can guide the locking block 312, which makes it easy for the personnel to slide the locking block 312 into the inner wall of the slot 306.

[0034] In addition, when personnel replace the support platform body 2 by moving the parts inside the replacement structure 3, after the personnel completely slide the guide block 303 and the locking block 312 out of the inner wall of the locking groove 306, the two compression springs 42 rebound, and the compression springs 42 drive the moving block 44 to move upward. The moving block 44 slides on the arc surface of the limit rod 43, and the moving block 44 drives the connecting block 45 to move upward. The connecting block 45 drives the protective pad 47 to move upward. The two protective pads 47 drive the support platform body 2 to move upward until part of the support platform body 2 slides out of the inner wall of the positioning groove 301. The protective pad 47 can protect the connecting block 45 and prevent the upper surface of the connecting block 45 from directly contacting the top wall of the connecting groove 46.
