Pipe bending machine

Abstract

The invention discloses a pipe bending machine which comprises a workbench (1) and a feeder (2). The feeder (2) is arranged on the outer side of one end of the workbench (1), and a first sliding rail(11) is arranged on the upper end face of the workbench (1). A clamping device (4) is slidingly arranged on the first sliding rail (11), and the bottom of the clamping device (4) can slide back and forth in the extending direction of the first sliding rail (11) through cooperation of the clamping lead screw and a clamping motor (43). The clamping device (4) comprises a pipe motor (41), and a clamping pipe (42) arranged at the end of an output shaft of the pipe motor (41). The clamping pipe (42) is in a polygon shape consistent with the shape of a pipe (5) to be bent. A bending device (3) is arranged between the clamping pipe (42) and the feeder (2). According to the pipe bending machine, the polygonal pipe can be continuously bent in multiple planes, and bending efficiency is improved.

Description

technical field [0001] The present invention relates to pipe benders. Background technique [0002] The pipe bending machine is used to bend the pipe fittings. At present, the mechanical pipe bending industry often uses the methods of pushing pipes, pulling bends, winding bends, pressing bends, etc. to process bends. The current pipe bender can only bend a straight The pipe fittings are bent in the horizontal plane. If the pipe fittings to be formed need to be bent in multiple planes, multiple pipe bending machines are required for bending or the pipe fittings in the first horizontal plane are bent, and then the pipe fittings are bent. Making another horizontal bend is inefficient. Contents of the invention [0003] In order to overcome the above disadvantages, the object of the present invention is to provide a pipe bender capable of continuously bending polygonal pipes on multiple planes and improving the bending efficiency. [0004] In order to achieve the above purpo...

Problems solved by technology

[0005] The beneficial effect of the pipe bender of the present invention is that the feeder is used to send the linear pipe fittings to the clamping device, and the straight pipe fittings sequentially pass through the first space between the parallel bending wheels and the guide wheels, and between the positioning member and the guide wheels. One channel, finally inserted into the clamping tube of the clamping device, the guide wheel and the positioning piece are used to position the straight pipe, the bending wheel can move 90 degrees along the outer circumference of the guide wheel from the position parallel to the positioning piece through the drive of the rotating motor ° or 180°, the pipe is bent in the first plane; when the pipe needs to be bent in the second plane, the positioning part and the bending wheel slide outward, and the rotating motor controls the rotating arm and then drives the bending wheel to reset , the clamping device is driven by the clamping motor through the clamping screw, so that it moves along the first slide rail to the bending device, the pipe motor controls the rotation of the clamping tube, and the tube inserted into the clamping tube will also rotate accordingly due to the polygonal structure , at this time, the bending wheel is driven by the rotating motor to move along the outer circumference of the guide wheel again, and the pipe is bent in the second plane to realize the bending of the pipe in two planes; when it is necessary to bend the pipe in the third or Return to the first plane to rotate, then recycle the above steps. Through the setting of the above structure, the elbow can be continuously bent in multiple planes, which improves the production efficiency of the elbow and solves the problem of the current elbow. The problem of low bending efficiency
