Pipe bending machine

Abstract

The invention relates to a pipe bending machine and belongs to the technical field of pipe bending device design. The pipe bending machine comprises a casing, a power switch, a motor, rotary shafts and grinding tools. The motor is arranged in the casing and connected with the rotary shafts through a transmission belt. Slots are formed in the casing, the rotary shafts stretch out of the casing through the slots, and the grinding tools are sleeved on portions of the rotary shafts, which stretch out of the casing. The pipe bending machine is characterized in that the rotary shaft comprises an upper rotary shaft, a lower left rotary shaft and a lower right rotary shaft; the grinding tools are arranged on the upper rotary shaft, the lower left rotary shaft and the lower right rotary shaft; a shifting groove is formed in the casing, the upper rotary shaft stretches out of the casing through the shifting groove, and the lower left rotary shaft and the lower right rotary shaft stretch out of the casing through the slots; a threaded press bar, a threaded hole and an effort-saving transmission apparatus are arranged at the top of the casing, the threaded press bar penetrates the threaded hole and presses on the upper rotary shaft through the effort-saving transmission apparatus, and a rotation handle is arranged on the threaded press bar. The pipe bending machine is reasonable and simple in structure, easy to manufacture and capable of reducing cost and improving production efficiency.

Description

technical field [0001] The invention relates to a pipe bending machine, which belongs to the technical field of pipe bending equipment design. Background technique [0002] Pipe benders are mainly used for bending steel pipes and other materials, and play an important role in the laying and repair of pipes in boilers, bridges, ships, furniture, decoration, etc. Due to the limitation of abrasive tools, you cannot bend the arc at will. For example, if it is a perfect circular abrasive tool, you can only bend it into a circular arc, but not an elliptical arc. If you want to bend other arcs, you can only change it. Abrasives, resulting in waste of materials and increased costs, but also reduce production efficiency. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a pipe bending machine which reduces cost and improves production efficiency. [0004] The object of the present invention is achieved through the fo...
