Hand-hydraulic pipe bender

Abstract

The invention discloses a manual hydraulic pipe bending machine, which comprises a hydraulic oil cylinder, an upper clamp, a lower clamp, a movable limiter, a pipe bending mold and a handle. One end of the hydraulic cylinder is provided with an upper clamp mounting seat, The other end of the hydraulic cylinder is provided with a handle mounting seat, and the lower clamping plate is connected to the underside of one end of the hydraulic cylinder located at the mounting seat of the upper clamping plate through bolts, and the upper surface of the upper clamping plate is provided with An angle ruler, a pair of connecting arms is provided on one side of the upper clamp, and a connecting shaft is provided on the connecting arm, and the connecting arm is connected with the mounting seat of the upper clamp through the connecting shaft, and the movable limiter is set The structure design of the present invention is reasonable, and the bending angle of the pipe can be controlled more flexibly by adopting the manual operation mode to bend the pipe, and the operation is simple and convenient. At the same time, the added angle ruler design can adjust the angle of the pipe Processing is more precise.

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. [0004] In order to solve the problems of t...
