Description

Technical Field

[0001] This utility model relates to the field of pipe bending technology, specifically a pipe bending machine for pipe processing. Background Technology

[0002] Pipe bending machines are machines used for bending pipes and can also be used as jacks. They are generally divided into CNC pipe bending machines and hydraulic pipe bending machines, and are used in pipeline laying and repair in power construction, railway and highway construction, bridges, ships and other fields.

[0003] However, in the existing technology, the existing pipe bending machine is placed on the construction site, but the existing pipe bending machine cannot provide auxiliary support for the pipe body during use. Without support, the pipe body is prone to misalignment during the bending process, which can easily lead to substandard quality. At the same time, the existing pipe bending machine does not have a stable clamping effect when bending the pipe body.

[0004] Therefore, we need a pipe bending machine for pipe processing to solve the problem of supporting the pipe body during bending processing of existing pipe bending machines, and also to clamp the pipe body during bending. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe bending machine for pipe processing, so as to solve the problem of support for pipe bending processing of existing pipe bending machines mentioned in the background art, and also to clamp the pipe body when bending.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe bending machine for pipe processing, comprising a bending machine body, wherein a mounting groove is provided on the top surface of the bending machine body, the surface of the mounting groove contacts the bottom surface of a support plate, a rotating hole is provided inside the support plate, the surface of a rotating pin is rotatably connected inside the rotating hole, the bottom end of the rotating pin is fixedly connected to the top surface of the mounting groove, an arc-shaped bracket is provided on the top surface of the support plate, a hydraulic cylinder is provided inside the arc-shaped bracket, and a clamping plate is fixedly connected to the end of the power output shaft of the hydraulic cylinder.

[0007] Preferably, the width of the mounting groove is equal to the width of the support plate, and the depth of the mounting groove is equal to the height of the support plate.

[0008] Preferably, the inner surface of the clamping plate is fixedly connected with an anti-slip pad, the clamping plate is arc-shaped, there are two clamping plates, and the clamping plates are symmetrically arranged along the center point of the arc-shaped bracket.

[0009] Preferably, the support plate has a guide groove inside, the surface of the guide groove is slidably connected to the surface of the guide block, and the top surface of the guide block is fixedly connected to the bottom surface of the arc-shaped bracket.

[0010] Preferably, the guide groove is convex in shape, and the surface of the guide groove is in contact with the surface of the guide block.

[0011] Preferably, a rubber pad is fixedly connected to the surface of the bending machine body, the surface of the rubber pad is in contact with the inner surface of the rotating baffle, and the end of the fixed pin is rotatably connected inside the rotating baffle. The cross-section of the fixed pin is T-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By opening an installation groove on the top surface of the bending machine body, the surface of the rotating pin is rotatably connected to the inside of the rotating hole, and then the bottom end of the rotating pin is fixedly connected to the top surface of the installation groove, thereby facilitating the rotation and storage of the support plate inside the installation groove, saving the floor space of the bending machine body. By setting an arc-shaped bracket on the top surface of the support plate, the end of the power output shaft of the hydraulic cylinder is fixedly connected to the surface of the clamping plate. When the hydraulic cylinder is started, the clamping plate moves inside the arc-shaped bracket. When the bending machine body is opened to bend the pipe, the clamping plate clamps and stabilizes the pipe surface. By opening a guide groove inside the support plate, the surface of the guide groove is slidably connected to the surface of the guide block, and the top surface of the guide block is fixedly connected to the bottom surface of the arc-shaped bracket. When the bending machine body is started to bend the pipe surface, and the clamping plate clamps the pipe surface at the same time, the arc-shaped bracket can move with the pipe on the top surface of the support plate. This further solves the problem of supporting the pipe bending process of the existing pipe bending machine, and also enables the pipe bending machine to clamp the pipe during bending.
