Description

Technical Field

[0001] The utility model belongs to the technical field of pipe making machines, in particular to a pipe making machine. Background Art

[0002] There are two main types of pipe making machines: one is the common high-frequency pipe welding machine, and the other is the stainless steel pipe making machine. The high-frequency pipe welding machine is mainly used to produce various iron pipes, water pipes, etc.; while the stainless steel pipe making machine is mainly used to produce various stainless steel decorative pipes, such as: pipes for stair handrails, pipes for anti-theft doors and windows, pipes for stair handrails, guardrails, etc.

[0003] The authorized patent with the known application number: CN202320012047.4 discloses a stainless steel pipe cutting machine, and its background technology proposes that "the prior art adopts a rotating handle to drive the nut to rotate, the threaded rod to move up and down, and the pipe wheel support frame to pull or push it to rotate around the rotating axis, thereby adjusting the angle of the steel pipe clamped between a pair of pipe clamping wheels, so that the weld of the steel pipe is aligned with the welding gun mouth for welding, but there is still a problem that the pipe clamping wheels are not equipped with quick-release facilities, which leads to the problem of time-consuming and labor-intensive mold replacement". For this reason, the technical solution to this problem is "including a workbench, a pre-rolling assembly is fixedly installed on the left side of the upper end of the workbench, forming assemblies are arranged on the left and right sides of the upper end of the workbench, and a welding assembly is fixedly installed on the middle part of the upper end of the workbench".

[0004] However, in the implementation of the relevant technology, it is found that the above technical solution has the following problems: although the effect of mold disassembly is achieved through the provided technical solution, it is not convenient for the staff to quickly install and disassemble the mold during use. During the disassembly process, it is necessary to use tools to screw the bolts on the mold frame and the pipe mold wheel and the connecting flange one by one. The disassembly process is cumbersome and time-consuming, which easily increases the labor intensity of the staff and the time for mold disassembly, thereby reducing the convenience and work efficiency of mold replacement and maintenance. To this end, we provide a pipe making machine to solve the above problems. Utility Model Content
