Problems solved by technology

However, because it uses a polishing wheel set to polish the elbow placed on the disc plane, there is inevitably a polishing dead angle, and the polishing of each part is uneven and the quality is poor, especially the corrugated multi-piece elbow cannot be polished.

Abstract

The invention discloses an automatic polishing machine for a bent pipe. The automatic polishing machine for the bent pipe comprises a base, a compound rotary polishing device, a bent pipe feeding device and a controller. The compound rotary polishing device is fixedly mounted on a bottom plate of the base; the bent pipe feeding device is located on the top of the base, and has two manipulators which are slidably connected to a longitudinal guide rail which moves left and right and are arranged on the top, respectively; each of the manipulators comprises a layer board, a bracket, a pneumatic chuck and a chuck support; the bracket is slidably connected to the layer board through a transverse slide rail, a longitudinal moving driving mechanism and a transverse moving driving mechanism are arranged on the layer board and the bracket, respectively, and the controller is in signal connection to the compound rotary polishing device and the bent pipe feeding device, respectively. The polishing machine disclosed by the invention can realize automatic control of bent pipe polishing, is simple to operate, low in labor intensity and high in polishing operating efficiency and uniformly polishes the external surface of the bent pipe, and the quality of the bent pipe is reliable.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to an automatic pipe polishing machine. Background technique [0002] Polishing has always been the bottleneck in the production process of elbows. Due to its complex and irregular shape, the traditional method mostly uses the operation of holding the elbow on a rotating abrasive belt, and constantly changing postures according to different parts of the polishing. This method is not only labor-intensive and inefficient, but also the polishing quality cannot be guaranteed, which has always troubled the bending pipe manufacturers. Since then, although the industry has continuously invested manpower and material resources, the technologies developed are generally not ideal. [0003] CN203804751U discloses a kind of elbow polishing machine, and it comprises frame, elevating frame, buffing wheel set, base, disc positioning plate, disc support plate, at least two discs, f...
