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.

Abstract

The invention discloses a hydraulic pipe bender, which provides a safe and reliable hydraulic pipe bender that can meet various specifications of pipe bending processing without changing the rotary die, saves time and labor, and solves the problem There are technical problems such as a set of bending dies and rotary dies that can only process pipes of one specification, low processing efficiency of bending pipes, and low safety and reliability. It includes the body and the hydraulic mechanism on the body. The hydraulic handle pushes the push rod upward through hydraulic oil, and the bending die is detachably connected to the top of the push rod. There is a lower guide groove on the top outer ring surface of the bending die that is compatible with the pipe to be processed. The two sides on the opposite side of the machine body are respectively connected to the rotary mold. The outer ring surface of the rotary mold forms several rolling areas along the circumferential direction. At least one type of pinching groove is provided on each rolling area. Together with the lower guide groove, the pipe to be processed of the corresponding specification is clamped for pipe bending processing.

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...
