Technical Field

[0001] The utility model relates to the technical field of ultra-thin PTFE gasket processing, and specifically, to a processing tool for ultra-thin PTFE gaskets. Background Technique

[0002] Ultra-thin PTFE gaskets, also known as polytetrafluoroethylene gaskets or Teflon gaskets, are a kind of sealing materials mainly made of polytetrafluoroethylene. Due to their excellent chemical stability, high and low temperature resistance, and excellent sealing performance, they are widely used in many fields, including the chemical industry, pharmaceutical industry, food industry, etc.

[0003] As disclosed in a Chinese patent: A processing tool for circular PTFE gaskets, application number: CN202323524034.4, includes a base and a positioning device. A driver is slidably connected to the upper surface of the base, and a drill bit is fixedly connected to the bottom end of the driver; a positioning device is provided on the surface of the base. The positioning device includes a placement rack, the surface of the placement rack is fixedly connected to the surface of the base, a slider is slidably connected to the inner wall of the placement rack, a limiting column is fixedly connected to the upper surface of the slider, and two limiting devices are provided at a position on the side wall of the base close to the placement rack. The limiting device includes a placement block, the side wall of the placement block is fixedly connected to the side wall of the base, a clamping block is slidably connected to the inner wall of the placement block, a limiting block is fixedly connected to the side wall of the placement rack close to the clamping block, and the clamping block is sleeved on the surface of the limiting block; by providing the placement rack, slider, limiting column and cushion plate, the gasket can be supported, and at the same time, the moving rack and the soft top can fix the gasket.

[0004] However, in the above technical solution, in the current industrial production environment, as a key sealing element, the processing quality and precision of ultra-thin PTFE gaskets are directly related to the performance and reliability of the final product. During the manufacturing process of ultra-thin PTFE gaskets, due to the intertwined influence of various factors, the mold may not achieve an ideal tightly fitting state when closing, resulting in gaps or misalignments, causing deviations in the thickness, flatness or contour of the processed gasket, thus unable to ensure the quality of the processed parts.

[0018] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figure 1 shown, a processing tooling for ultra-thin PTFE gaskets includes a base 1, a lower tooling die 2 is arranged on the base 1, an upper tooling die 3 is arranged on one side of the lower tooling die 2, a V-shaped die closing groove 4 is arranged on the side of the lower tooling die 2 close to the upper tooling die 3, a V-shaped die closing block 5 is arranged in the V-shaped die closing groove 4, a threaded hole 6 is arranged on one side of the V-shaped die closing groove 4, a through groove 7 is arranged on the upper tooling die 3, and a bolt 8 is arranged in the through groove 7.

[0020] As Figure 2 shown, in another embodiment of the present utility model, the bolt 8 includes a bolt base 801, a driving connection block 802 is fixedly arranged on one side of the bolt base 801, a thread 803 and a chute 804 are arranged on the side of the bolt base 801 far from the driving connection block 802;

[0021] A guide sliding column 805 is slidably arranged in the chute 804, a spring 806 is fixedly arranged at one end of the guide sliding column 805, a rotating disc 807 is fixedly arranged on one side of the spring 806. When it is necessary to close the die between the lower tooling die 2 and the upper tooling die 3, the driving connection block 802 is connected to a driving device, and then the guide sliding column 805 is inserted into the threaded hole 6. The bolt base 801 is guided by the guide sliding column 805, so that the bolt base 801 can quickly align with the threaded hole 6, facilitating subsequent die closing operations. Then, the bolt base 801 is driven to rotate by the driving connection block 802, the bolt base 801 drives the thread 803 to rotate, and then the bolt base 801 moves towards the direction close to the lower tooling die 2 through the threaded hole 6 and the thread 803. The guide sliding column 805 gradually enters the chute 804, the spring 806 deforms, and the bolt base 801 drives the upper tooling die 3 to move, so that the lower tooling die 2 and the upper tooling die 3 are closed.

[0022] The working principle of this ultra-thin PTFE gasket processing tooling:

[0023] During use, first place the workpiece between the lower tooling die 2 and the upper tooling die 3. Then insert the guiding slide post 805 into the threaded hole 6 to guide the bolt base 801 through the guiding slide post 805, enabling the bolt base 801 to quickly align with the threaded hole 6, thus facilitating the subsequent mold closing operation. Then drive the connecting block 802 to drive the bolt base 801 to rotate. The bolt base 801 drives the thread 803 to rotate. Subsequently, through the threaded hole 6 and the thread 803, the bolt base 801 moves towards the direction close to the lower tooling die 2. The guiding slide post 805 gradually enters the chute 804, and the spring 806 deforms. The bolt base 801 drives the upper tooling die 3 to move, thereby closing the lower tooling die 2 and the upper tooling die 3. And use the V-shaped mold closing groove 4 and the V-shaped mold closing block 5 for guiding, so that the lower tooling die 2 and the upper tooling die 3 can be completely fitted, preventing gaps or misalignments, and thus ensuring the quality of the workpiece.

[0024] Obviously, the above-mentioned embodiments of the present utility model are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
