A kind of pipe fitting punching machine

Abstract

The invention provides a pipe fitting punching machine, and belongs to the technical field of machines. The pipe fitting punching machine solves the technical problems that due to the fact that an existing pipe punching device only positions a pipe with a core rod which is prone to deformation, the punching precision is low. The pipe fitting punching machine comprises a base. A driving shaft is arranged on the base in an axial-fixing and circumferential-rotation mode. A positioning plate is arranged above the base and fixed to the base through a connecting support. The driving shaft is connected with a power mechanism which can drive the driving shaft to rotate. A rotating disc is fixedly arranged in the middle of the driving shaft. A core rod with which a pipe fitting is sleeved is fixedly arranged on the rotating disc. A supporting device is arranged at the lower portion of the other end of the core rod. A plurality of through holes are formed in the core rod. The core rod is further sleeved with a positioning device which can position the pipe fitting to the core rod. A punching device is further arranged at the lower portion of the positioning plate. The punching device comprises a drill bit which can be located over the through holes of the core rod. The pipe fitting punching machine has the advantages of being high in punching efficiency and high in mechanical degree.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a punching machine, in particular to a punching machine for pipe fittings. Background technique [0002] During the drilling process of pipe fittings, the pipe fittings are generally placed on a mandrel with one end suspended in the air, and then the drilling process is carried out; because one end of the mandrel fixing the pipe fittings is suspended in the air, its bearing capacity is poor. It is difficult to guarantee the punching accuracy in the process. [0003] After searching, a pipe punching device [patent number: ZL200910208278.7; authorized announcement number: CN101708520B] is disclosed in the Chinese patent literature. This pipe punching device includes a frame and a workbench installed on the frame. A punching device is installed on the workbench. A pipe clamping device and a material unloading device that cooperate with the punching device are installed on the workb...

Problems solved by technology

[0004] Although the pipe punching device disclosed in this patent can process holes of various shapes on the pipe wall of a long pipe, the pipe punching device only uses a mandrel to position the pipe, and the mandrel is easily deformed, resulting in poor punching accuracy. It is difficult to guarantee, and the service life of the pipe punching device is short, so it is necessary to design a pipe punching machine
