Description

Technical Field

[0001] The utility model relates to the technical field of pipe end necking tooling, in particular to a pipe end necking tooling for a numerical control machine tool. Background Technique

[0002] A pipe end necking tooling is a device specifically used for necking and connecting pipes. It mainly consists of components such as a base, a pipe clamp, a guiding plate, a positioning block, and a necking module. This tooling realizes pipe connection through the pressure of the necking module and the deformation of the pipe. Compared with the traditional manual necking method, the pipe end necking tooling can realize automatic necking joints, thus significantly improving production efficiency and the quality of necking joints. This tooling is widely used in high-pressure pipe systems, such as the petroleum and petrochemical, natural gas, and metallurgy industries. When using the pipe end necking tooling, due to the large friction force when the necking head contacts the pipe fitting, it is usually necessary to spray a certain amount of lubricating oil at the front end of the pipe fitting to prevent the key from overheating due to friction and causing deformation. The spraying of lubricating oil can also reduce the friction force when the pipe fitting contacts the necking head. However, this may also result in a large amount of oil stains on the workbench surface, which not only affects the operation of the machine but also increases the difficulty of cleaning the surface. In addition, the pipe end necking tooling can also be installed on a numerical control machine tool to realize rapid pipe end necking, which is not only convenient and fast but also can reduce the pipe body handling cost and further improve production efficiency. Generally speaking, the pipe end necking tooling is an important device in the process of pipe connection, with the advantages of automation, high efficiency, precision, etc., and is an indispensable part of modern industrial production.

[0003] Currently, when fixing the existing pipe end necking tooling for a numerical control machine tool, it usually needs to be fixed by multiple fixing bolts. At present, the fixing method is manual operation and professional tools are required for the installation of the fixing bolts, resulting in cumbersome installation and disassembly of the pipe end necking tooling, which is time-consuming and laborious and cannot bring convenience to users, affecting the convenience of operators. Therefore, a pipe end necking tooling for a numerical control machine tool is proposed to solve the above problems. Content of the Utility Model
