Pipe bending device

Abstract

The invention discloses a pipe bending device. A workbench is sequentially provided with a pipe bending mold, a clamping mechanism and a positioning mechanism; a pipe bending guiding wheel of the pipebending mold is installed on the workbench through an R mold base; a screw penetrates through the center position of the pipe bending guiding wheel to be arranged; the pipe bending guiding wheel is connected with a gear through the screw; the gear is engaged with a rack, so that the pipe bending guiding wheel is synchronously driven to rotate; a front clamping plate of the clamping mechanism andthe pipe bending guiding wheel are oppositely arranged; the front clamping plate is connected with a piston rod of a front clamping plate cylinder; the front clamping plate cylinder is used for driving the front clamping plate to move relative to the pipe bending guiding wheel; and a rear clamping plate cylinder of the positioning mechanism drives a rear clamping plate to move relative to a core rod. The pipe bending mold is matched with the core rod, and has high and wide applicability to a core rod material, the bending angle, the force degree and the shape of the pipe bending mold on the core rod can meet the requirement of sufficient consistency, and the finished product rate is greatly increased; and it is guaranteed that the curvature radius of each time of pipe bending is consistentand stable, and then it is guaranteed that after product bending, the pressing flattening rate meets the requirement.

Description

technical field [0001] The invention belongs to the technical field of pipe bending equipment, and in particular relates to a pipe bending equipment. Background technique [0002] The bent pipe is bent with a complete set of bending dies. The bending radius depends on the material properties, bending angle, the allowable amount of thinning on the outside of the bent pipe wall, the size of the inner wrinkle, and the size of the ellipticity of the bend. The current pipe bending method is generally difficult to apply to thin-walled small-radius core rod pipes. In the prior art, corresponding bending dies are provided on the workbench, and the mandrel to be bent is placed in a corresponding position, and the operator manually performs the pipe bending operation. It has the following technical problems: 1. The operation efficiency is low, time-consuming and labor-intensive, and the labor cost is high. 2. The section of the bent pipe fittings will be excessively deformed, or the...
