Description

Technical Field

[0001] This utility model relates to the field of punching fixture technology, and in particular to an integrated punching fixture. Background Technology

[0002] A punching fixture is a specialized tool that applies a concentrated load to a material using a die, causing it to break off into a conical shape under shearing force. Its working principle is based on punching technology, utilizing the cutting edge of the die to shear or punch the material, achieving separation. During the punching process, the material fractures and separates after elastic and plastic deformation, forming a smooth cut.

[0003] In the edge processing stage of existing fabric-covered rubber diaphragms, a step-by-step operation mode of "processing the inner diameter first and then the outer diameter" is usually adopted. This process requires splitting into two independent processes, which not only increases the time spent on product turnover between processes, but also directly extends the overall manufacturing cycle. At the same time, each process requires manual operation, which further increases labor costs.

[0004] To address this, an integrated punching fixture is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated punching fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated punching fixture, comprising a base plate, a core at the top of the base plate, a rubber diaphragm placed in the core, and residual edge material connected to the rubber diaphragm; a punching assembly on the base plate, the punching assembly being used to simultaneously remove the edge material on both the inner and outer diameters of the rubber diaphragm, the punching assembly including an outer blade hammer fixedly connected to the base plate, an inner blade hammer fixedly connected to the middle of the base plate, and a pressure plate at the top of the core for pressing the edge material.

[0007] Preferably, a bracket is fixedly connected to the base plate, and a cylinder is fixedly installed on the bracket, with the output end of the cylinder fixedly connected to the pressure plate.

[0008] Preferably, the pressure plate is provided with an outer pressure part for extruding the outer diameter edge material, and the pressure plate is provided with an inner pressure part for extruding the inner diameter edge material.

[0009] Preferably, both the outer and inner blade hammers are provided with conical cutting edges, which are used to cut and separate the edge material in conjunction with the pressure plate.

[0010] Preferably, a spring is fixedly connected between the core and the base plate, the core is slidably connected to the outer blade hammer, and the core is slidably connected to the inner blade hammer, with the inner diameter opening of the rubber diaphragm located at the top of the inner blade hammer.

[0011] Preferably, the inner blade hammer has a discharge channel for discharging material from the inner diameter edge, and the inner blade hammer has an inclined surface.

[0012] Preferably, the core has a material feeding groove and a material discharge pipe, and the material discharge pipe is threadedly connected to a sealing plate.

[0013] The beneficial effects of this utility model are: This invention features a punching assembly that, when the rubber diaphragm is placed on the core, a drive cylinder pushes the pressure plate downwards. This causes the outer and inner pressure parts of the pressure plate to engage with the outer and inner cutting hammers, respectively, thereby punching and separating the edge material on the outer and inner diameters of the rubber diaphragm. This achieves the simultaneous removal of edge material from both the inner and outer diameters without the need for separate processing, thus improving edge material handling efficiency and reducing costs. Furthermore, after punching, the edge material on the inner diameter can fall onto the inclined surface through the discharge channel and slide into the discharge trough for collection. Finally, the collected edge material can be discharged by opening the sealing plate, eliminating the need for manual handling of the smaller inner diameter edge material at the inner cutting hammer.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0019] like Figures 1 to 5 As shown, a specific embodiment of this utility model provides an integrated punching fixture, including a base plate 1, a core 2 at the top of the base plate 1, a rubber diaphragm 3 placed in the core 2, and residual edge material 4 connected to the rubber diaphragm 3. During the production process, residual edge material 4 remains on both the outer and inner diameters of the rubber diaphragm 3, which needs to be separated and removed to prevent it from affecting product quality. A punching assembly is provided on the base plate 1, which is used to remove the edge material 4 on both the inner and outer diameters of the rubber diaphragm 3 at the same time. By setting the punching assembly, the edge material 4 on both the outer and inner diameters of the rubber diaphragm 3 can be separated and removed at the same time, eliminating the need to remove the edge material 4 from two different positions separately, thereby improving the processing efficiency of the edge material 4 and integrating two processes into one process, thereby reducing labor costs. The punching assembly includes an outer blade hammer 5 fixedly connected to the base plate 1, an inner blade hammer 6 fixedly connected to the middle of the base plate 1, and a pressure plate 7 for squeezing the edge material 4 at the top of the core 2.

[0020] like Figures 1 to 5As shown, specifically, a bracket 8 is fixedly connected to the base plate 1, and a cylinder 9 is fixedly installed on the bracket 8. The output end of the cylinder 9 is fixedly connected to the pressure plate 7. The pressure plate 7 is provided with an outer pressure part 10 for squeezing the outer diameter edge material 4 and an inner pressure part 11 for squeezing the inner diameter edge material 4. When removing the edge material 4 on the outer and inner diameters of the rubber diaphragm 3, the worker places the rubber diaphragm 3 into the core 2, so that the outer diameter edge material 4 on the rubber diaphragm 3 can be at the top of the outer blade hammer 5, while the inner diameter edge material 4 of the rubber diaphragm 3 is pressed so that it is at the inner blade hammer 6. At the middle position, the cylinder 9 is then activated to push the bottom pressure plate 7 downward. The downward movement of the pressure plate 7 causes the outer pressure part 10 on the pressure plate 7 to gradually approach the edge material 4 on the outer blade hammer 5, and the inner pressure part 11 to gradually approach the edge material 4 on the inner blade hammer 6. Both the outer blade hammer 5 and the inner blade hammer 6 are provided with conical cutting edges, which are used to cooperate with the pressure plate 7 to cut and separate the edge material 4. A spring 12 is fixedly connected between the core 2 and the base plate 1. The core 2 is slidably connected to the outer blade hammer 5 and the inner blade hammer 6. The inner diameter opening of the rubber diaphragm 3 is located corresponding to the inner blade hammer 6. At the top, when the outer pressure part 10 squeezes the edge material 4 on the outer-bladed hammer 5, the generated squeezing force and the cooperation of the cutting edge on the outer-bladed hammer 5 allow the edge material 4 on the rubber diaphragm 3 to separate from its outer diameter. Simultaneously, the inner pressure part 11 squeezes the edge material 4 on the inner-bladed hammer 6. Under the cooperation of the squeezing force and the cutting edge on the inner-bladed hammer 6, the edge material 4 on the rubber diaphragm 3 separates from its inner diameter. At this time, under the action of the pressure plate 7, the edge material 4 on both the inner and outer diameters of the rubber diaphragm 3 can be removed simultaneously. During the squeezing process of the pressure plate 7, the pressure plate 7 will... The diaphragm 3 is subjected to a certain pressure, which squeezes the rubber diaphragm 3 to move downward, thereby pushing the core 2 to move downward a small distance. The downward movement of the core 2 causes the spring 12 to contract and generate a reaction force. When the edge material 4 separates from the rubber diaphragm 3, the cylinder 9 drives the pressure plate 7 to move upward to release the pressure brought by the pressure plate 7. Under the reaction force of the spring 12, the core 2 pushes the rubber diaphragm 3 upward. At this time, the movement of the rubber diaphragm 3 and the edge material 4 form a tearing action, which tears and breaks the tiny unbroken parts of the edge material 4, so that the edge material 4 can be better removed.

[0021] like Figures 1 to 5As shown, specifically, the inner blade hammer 6 has a discharge channel 13 for discharging the inner diameter edge material 4. The inner blade hammer 6 has an inclined surface 14, the core 2 has a discharge groove 15, and the core 2 has a discharge pipe 16. A sealing plate 17 is threaded into the discharge pipe 16. After the outer diameter edge material 4 on the rubber diaphragm 3 is cut off and separated, it is located at the top of the outer blade hammer 5. At this time, it is convenient to handle the residual edge material 4 and remove it directly. The edge material 4 located at the inner blade hammer 6 is in the middle of the entire device. Furthermore, the edge material 4 at the inner diameter is relatively small, making it inconvenient for workers to remove by hand. However, the setting of the discharge channel 13 allows the edge material 4 at the inner diameter to be discharged downwards through the discharge channel 13 after being cut and separated. It falls onto the inclined surface 14 and gradually slides into the discharge trough 15. When there is too much material in the discharge trough 15, the sealing plate 17 is rotated to detach it from the discharge pipe 16. At this time, it is convenient to discharge the edge material 4 stored in the discharge trough 15 outwards through the discharge pipe 16, thereby centrally processing the separated edge material 4 at the inner diameter.
