Hydraulic pipe bender

Abstract

The invention discloses a hydraulic pipe bender, and provides a hydraulic pipe bender which can meet the pipe bending machining of pipes of various specifications under the condition that a rotating die does not need to be replaced, saves time and labor during machining, and is safe and reliable. The technical problems that in the prior art, a set of bending dies and rotating dies can only machinepipes of one specification, the pipe bending machining efficiency is low, and the safety and reliability are low are solved. The hydraulic pipe bender comprises a machine body and a hydraulic mechanism arranged on the machine body, wherein a hydraulic handle on the hydraulic mechanism pushes a push rod upwards through hydraulic oil; the top end of the push rod is detachably connected with a bending die; a lower guide groove matched with a to-be-machined pipe is formed in the outer ring face of the top of the bending die; the two sides, opposite to the bending die, of the upper portion of themachine body are rotationally connected with rotating dies correspondingly; a plurality of rolling areas are formed on the outer ring faces of the rotating dies in the circumferential direction; and each rolling area is provided with at least one pipe clamping groove of one specification. The pipe clamping grooves and the lower guide groove jointly clamp the to-be-machined pipes of the corresponding specifications for pipe bending machining.

Description

technical field [0001] The invention relates to a hydraulic pipe bender, in particular to a hydraulic pipe bender capable of processing pipes of various specifications without changing bending dies. Background technique [0002] The hydraulic pipe bender is a pipeline tool that uses the handle to press the ejector rod to compress the hydraulic oil, and is driven by the hydraulic system to press the pipe bending die to complete the pipe bending. There is usually only one arc groove on the bending die and rotary die of the existing hydraulic pipe bender for pipe bending processing. During the pipe bending process, it is necessary to replace the bending die and rotary die of the corresponding specifications to realize the pipe bending process, which not only takes time and effort, but also leads to low efficiency of the pipe bending process, and in some special occasions, such as working at heights, it is very easy to cause safety accidents. At the same time, frequent replacem...

AI Technical Summary

Problems solved by technology

[0003] The present invention mainly provides a kind of pipe bending processing that can meet various specifications without changing the rotating die, and the bending processing saves time and labor, and is safe and reliable hydraulic pipe bender, which solves the problems existing in the prior art. A set of bending dies and rotating dies can only process pipes of one specification. When changing the pipe diameter, the bending dies and rotating dies need to be replaced accordingly. The processing efficiency of bending pipes is low, and the safety and reliability are low.
