Description

Technical Field

[0001] The present invention relates to a punching device for pipe fittings joints, belonging to the technical field of punching devices. Background Art

[0002] Pipe fittings joints are one of the automotive parts, mainly used for connecting between automotive pipelines. When a pipe fittings joint is connected to a pipeline, it is necessary to ensure both the sealing performance at the connection port and the accuracy of the connection angle. To ensure the sealing performance, the existing pipe fittings joints generally adopt the method of reverse buckling at the pipe orifice, and at the same time, a notch is punched at a specific position on the pipe wall of the pipe orifice to ensure the assembly angle, that is, during the assembly process of the joint and the pipeline, the notch of the joint is aligned with a specific position of the pipeline (such as a position with a mark) for assembly.

[0003] However, for a pipe fittings joint with reverse buckling at the pipe orifice, when punching a notch at the pipe wall of the pipe orifice, due to the interference between the concave die and the reverse buckling position of the pipe orifice, it is very difficult to quickly remove the concave die from the joint after punching, resulting in low punching efficiency.

The guiding column and the first spring column play a guiding role during the process of the hosting positioning block 302 being compressed downward and springing upward, so that the hosting positioning block 302 does not deviate during the process of compression and springing.

[0033] The upper die assembly 6 includes a second support seat 601 and a pressing block 602. An upper positioning groove 603 that cooperates with the lower positioning groove 303 is provided on the pressing block 602. One end of the second support seat 601 is connected to the punching assembly 5. The pressing block 602 is installed at the lower part of the second support seat 601 through a plurality of compression springs II 604. A guiding column is further provided between the second support seat 601 and the pressing block 602. A second spring column is provided in the middle of the compression spring II 604. One end of the second spring column is fixedly connected to the pressing block 602, and the other end of the second spring column can slide through the second support seat 601. The guiding column and the second spring column play a guiding role during the process of the pressing block 602 being compressed downward and springing upward, so that the pressing block 602 does not deviate during the process of compression and springing.

[0034] The wire diameter of the compression spring I 304 is smaller than that of the compression spring II 604. Therefore, after the equipment is started, the pressing block 602 contacts the hosting positioning block 302, and it is easier to press the pipe fittings joint 8.

[0035] The punching die 4 includes a punching die body 401, a recessed portion 402 and a punching foot 403. The punching die body 401 is fixed on the lower workbench 2.
