Description

technical field

[0001] The invention relates to a manual hydraulic pipe bending machine, which belongs to the field of hydraulic equipment. Background technique

[0002] Pipe benders can be roughly divided into CNC pipe benders, hydraulic pipe benders, etc.; they are mainly used for laying and repairing pipes in power construction, highway and railway construction, boilers, bridges, ships, furniture, decoration, etc.; their defects are metal During the bending process of the pipe, its bending angle cannot be precisely controlled. At the same time, most pipe bending machines are operated automatically or semi-automatically. The structure is too complicated and the processing is expensive, so it is not suitable for processing a small amount of pipes. Contents of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a manual hydraulic pipe bender.
