Description

Technical Field

[0001] The utility model relates to the technical field of aluminum pipe processing, in particular to an aluminum square pipe arc pressing machine. Background Technique

[0002] An aluminum square pipe is a hollow metal pipe, which has the advantages of light weight, easy shaping, convenient use, etc. And when processing aluminum square pipes, it is often necessary to carry out pressing and shaping treatment to press the aluminum square pipe into a certain arc, so as to facilitate processing such as welding. The existing arc pressing devices have low working efficiency and low arc precision. When bending aluminum square pipes manually, it is easy to cause different bending arcs, resulting in large deviations in the manufactured trough cover plate frame workpieces.

[0003] Chinese Patent with the authorization announcement number of CN217369916U discloses an aluminum square pipe arc pressing machine device, which includes a workbench. An arc-shaped groove is opened at the top of the workbench. A top plate is fixedly connected to the top of the workbench. Two cylinders are fixedly installed on the top of the top plate. A bearing plate is arranged at the bottom of the top plate. A pressing seat is fixedly connected to the bottom of the bearing plate. The bottom end of the cylinder penetrates through the top plate and is fixedly connected to the top of the bearing plate. In this utility model, the height of the baffle is changed by driving the baffle with an electric push rod. The distance between two adjacent baffles can be changed by the cooperation between the electromagnetic block and the magnetic force plate, so as to play a certain restriction on aluminum square pipes of different specifications and avoid the movement of aluminum square pipes during the arc pressing operation, which affects the arc pressing quality. The setting of the buffer mechanism can improve the buffer performance of the device and avoid the problem that the arc pressing equipment rushes towards the aluminum square pipe quickly and damages the aluminum square pipe.

When the length of the aluminum square pipe is short, both ends cannot be restricted by the baffles, so that the position of the aluminum square pipe in the arc-shaped groove cannot be fixed, resulting in unqualified processing of the aluminum square pipe.
