Description

Technical Field

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

[0002] The full name of the PTFE gasket is polytetrafluoroethylene gasket. It is also called PTFE gasket or Teflon gasket abroad. It is made of polytetrafluoroethylene rods, tubes, and plates through mechanical turning or cutting into flat gaskets, V-shaped gaskets, piston rings, ball valve gaskets, etc. It has good characteristics such as corrosion resistance, anti-aging, and non-conductivity. The pH value of polytetrafluoroethylene is 0 - 14 (except for molten alkali metals and fluorine under high temperature and high pressure). It can have good mechanical strength between -100°C and 100°C. During the processing process, it is necessary to continuously place the material plate, and a processing device that facilitates the installation of the material plate is required.

[0003] The existing patent with the publication number of CN207373312U and the name of "a processing tool for polytetrafluoroethylene gaskets" relates to a processing tool for polytetrafluoroethylene gaskets. The processing tool for polytetrafluoroethylene gaskets includes a body die for processing the gasket body of the polytetrafluoroethylene gasket and a structure hole die for processing the structure holes of the gasket. The body die includes an outer peripheral surface die for processing the outer contour of the polytetrafluoroethylene gasket and a mating hole die for processing the contour of the mating hole of the polytetrafluoroethylene gasket. The structure hole die includes a positioning pin hole die for processing the positioning pin holes and a screw hole die for processing the screw holes. The body die and the structure hole die are of an integral structure or a split structure. By using the processing tool for polytetrafluoroethylene gaskets to mechanize the production of polytetrafluoroethylene gaskets, the labor intensity of operators is reduced, the production efficiency is improved, and at the same time, the appearance of burrs on the end face of the polytetrafluoroethylene gasket is avoided by directly using the tool for cutting, ensuring the qualification rate of the product.

[0004] The above device mechanizes the production of polytetrafluoroethylene gaskets through the processing tool for polytetrafluoroethylene gaskets, reducing the labor intensity of operators and improving the production efficiency. At the same time, the appearance of burrs on the end face of the polytetrafluoroethylene gasket is avoided by directly using the tool for cutting. However, this device is not convenient for fixing the material plate and continuous processing, and cannot well meet people's usage requirements. In view of the above situation, technological innovation is carried out on the basis of the existing gasket processing tool. Content of the Utility Model

Support feet are installed on the left and right sides below the platform, and the support feet are welded to the platform. The backing plate is installed above the platform, and a fixing component is arranged inside the backing plate. A push rod is arranged on the right side of the backing plate, and a first telescopic rod is installed on the right side of the push rod.

[0011] Further, an installation block is wrapped around the outer periphery of the damping rod, and a hydraulic rod is installed above the installation block. The hydraulic rod presses down the installation block, and the pressing block presses on the material plate.

[0012] Further, a second telescopic rod is installed below the installation block, and the second telescopic rod is inlaid with the installation block. The second telescopic rod extends to push out the gasket stuck in the tool bit, and the gasket falls onto the backing plate.

[0013] Further, a tool bit is installed below the installation block, and the tool bit is inlaid with the installation block. The tool bit presses on the material plate to cut off the gasket, and the gasket is stuck in the tool bit and rises with the hydraulic rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: Place the material plate on the backing plate, loosen the sliding plate, and the spring pushes the sliding plate to slide on the sliding rod to abut the material plate against the limiting plate for convenient fixation.

A push rod 4 is arranged on the right side of the backing plate 2, and a first telescopic rod 5 is installed on the right side of the push rod 4. The fixing component 3 includes a limit plate 301, a sliding rod 302, a sliding plate 303 and a spring 304. A sliding rod 302 is arranged at the front end of the limit plate 301. The sliding plate 303 is slidably connected to the periphery of the sliding rod 302, and a spring 304 is installed at the front end of the sliding plate 303. A chute 7 is installed in the middle below the platform 1, and the chute 7 is welded to the platform 1. A waste box 6 is slidably connected inside the chute 7, and a finished product box 8 is arranged on the right side of the waste box 6. Pull the sliding plate 303, place the material plate on the backing plate 2, release the sliding plate 303, and the spring 304 pushes the sliding plate 303 to slide on the sliding rod 302, pressing the material plate against the limit plate 301 for convenient fixing. After processing, the hydraulic rod 14 is lifted, the first telescopic rod 5 extends, and the waste material plate is pushed from the opening on the platform 1 into the waste box 6 through the push rod 4. The second telescopic rod 13 extends to push out the gasket stuck in the tool bit 12. The gasket falls onto the backing plate 2, and as the first telescopic rod 5 contracts, the push rod 4 pushes the gasket to the opening on the other side and falls into the finished product box 8. The waste box 6 and the finished product box 8 are slidably installed below the platform 1 through the chute 7 for convenient disassembly

[0023] As Figure 1 and Figure 3 shown, a pressing block 11 is arranged above the backing plate 2, and a damping rod 10 is installed above the pressing block 11. An installation block 9 is wrapped around the periphery of the damping rod 10, and a hydraulic rod 14 is installed above the installation block 9. A second telescopic rod 13 is installed below the interior of the installation block 9, and the second telescopic rod 13 is inlaid with the installation block 9. A tool bit 12 is installed below the installation block 9, and the tool bit 12 is inlaid with the installation block 9. The hydraulic rod 14 presses down the installation block 9, and the pressing block 11 presses on the material plate to tightly press the material plate. As it is pressed down, the damping rod 10 contracts, and the tool bit 12 presses on the material plate to cut out the gasket, and the gasket gets stuck in the tool bit 12.

The hydraulic rod 14 presses down the mounting block 9, and the pressing block 11 presses on the material plate to clamp the material plate. As the damping rod 10 contracts during the downward pressing, the cutter head 12 presses on the material plate to cut out the gasket, and the gasket gets stuck in the cutter head 12. As the hydraulic rod 14 rises, the first telescopic rod 5 extends, and through the push rod 4, the waste material plate is pushed from the opening on the platform 1 into the waste bin 6. The second telescopic rod 13 extends to push out the gasket stuck in the cutter head 12, and the gasket falls onto the backing plate 2. And as the first telescopic rod 5 contracts, the push rod 4 pushes the gasket to the other side's opening and it falls into the finished product box 8. The waste bin 6 and the finished product box 8 are slidably installed under the platform 1 through the chute 7 for convenient disassembly.
