Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a tool for quickly disassembling a cylindrical punch. Background Art

[0002] The traditional disassembly method is that the maintenance personnel knock on the top of the cylindrical punch to make it fall off. Since the cylindrical punch needs high-precision installation to keep it stable during daily use, the blade must also be sharp. Therefore, during installation, the upper half of the cylindrical punch is usually inserted into the punch fixing plate, and then the cylindrical punch is fixed with screws from the upper template. When repairing and replacing the cylindrical punch, the maintenance personnel first remove the screws that fix the cylindrical punch in the upper template, and then use a hammer and iron rod tools to knock on the top of the cylindrical punch from the screw through hole of the upper template to make it fall off the punch fixing plate. This disassembly requires the use of a hammer to knock, which not only increases the risk of injury to the maintenance personnel, but also easily damages the threaded hole above the cylindrical punch for fixing. In addition, when the punch falls off the fixing plate, there is a risk of falling to the ground and damaging the blade. The damaged cylindrical punch needs to be reprocessed, which not only increases the maintenance cost but also affects the normal use of the mold, reducing production efficiency.

[0003] In summary, the utility model designs a tool for quickly disassembling a cylindrical punch. Utility Model Content

[0004] In view of the problem that it is difficult to disassemble the cylindrical punch in the daily stamping die in the prior art, the utility model aims to provide a tool for quickly disassembling the cylindrical punch. After using the quick disassembly tool, it avoids the possibility of injury to the maintenance personnel and makes the disassembly of the cylindrical punch convenient and quick, and will not cause damage to the cylindrical punch. The overall replacement efficiency is improved, which ensures that the efficiency is improved while reducing the maintenance cost and increasing safety.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a tool for quickly disassembling a cylindrical punch, including a quick disassembly tool, the quick disassembly tool including a welding connecting rod, a nut, a sleeve handle and a steel gasket, one end of the welding connecting rod is provided with an external thread, a nut is provided at the external thread, the other end of the welding connecting rod is provided with a steel gasket, and a sleeve handle is provided between the nut and the steel gasket.

[0006] Preferably, the welded connecting rod is a T-shaped structure.

[0007] Preferably, the external thread cooperates with the threaded hole at the bottom of the cylindrical punch.

[0008] The utility model has the following beneficial effects:

[0009] Compared with the traditional disassembly, the utility model is more convenient, faster and safer. The whole disassembly process is fast and convenient, and it avoids damaging the lower blade part and the upper threaded hole part of the cylindrical punch, avoids secondary maintenance caused by improper operation of the cylindrical punch, improves the efficiency of replacing the cylindrical punch, greatly saves the maintenance and replacement time, and reduces the cost at the same time.

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] Reference Figure 1-4 This specific embodiment adopts the following technical solution: a tool for quickly disassembling a cylindrical punch, comprising a quick disassembly tool 1, wherein the quick disassembly tool 1 comprises a welding connecting rod 10, a nut 11, a sleeve handle 12 and a steel gasket 13, an external thread 14 is arranged at one end of the welding connecting rod 10, a nut 11 is arranged at the external thread 14, a steel gasket 13 is arranged at the other end of the welding connecting rod 10, and a sleeve handle 12 is arranged between the nut 11 and the steel gasket 13.

[0017] It is worth noting that the welding connecting rod 10 is a T-shaped structure.

[0018] In addition, the external thread 14 cooperates with the threaded hole 5 at the bottom of the cylindrical punch 4 .

[0019] like Figure 4 As shown, the upper part of the cylindrical punch has a threaded hole for fixing on the upper template; the lower part has a threaded hole that matches the external teeth (external threads) on the quick release tool for connecting with the quick release tool.

[0020] The method of using this specific embodiment is as follows: when using the quick-release tool, first remove the screws that fix the cylindrical punch on the upper template 3, then twist the front end of the welding connecting rod 10 with threaded external teeth into the threaded hole at the bottom of the cylindrical punch, connect the quick-release tool to the cylindrical punch, then hold the sleeve handle tightly with one hand and raise it to the nut and then slide it down forcefully, let the sleeve handle hit the steel gasket below, use inertia to remove the cylindrical punch 4 from the punch fixing plate 2, and finally remove the cylindrical punch from the quick-release tool. The whole process is fast and convenient, and avoids damaging the lower blade part and the upper threaded hole part of the cylindrical punch 4, avoids secondary repairs caused by improper operation, improves the efficiency of replacing cylindrical punches, greatly saves maintenance and replacement time, and reduces costs.
