A pipe bending machine for the manufacture of square aluminum pipes

Abstract

The invention relates to a pipe bending machine for manufacturing a square aluminum pipe. The pipe bending machine comprises a bottom plate and a workbench. A clamping frame is mounted on the workbench in a sliding mode. A fastening bolt is mounted on the clamping frame. A rack is welded to the clamping frame. The lower end of the rack is provided with an incomplete gear which is connected with a motor. A transmission gear is arranged below the incomplete gear and is connected with a transmission shaft. The transmission shaft is connected with a right belt pulley. A left belt pulley is arranged on the left side of the right belt pulley. The left belt pulley is connected with an auxiliary shaft. A big rotary wheel is mounted at the front end of the auxiliary shaft. A lifting bending frame is arranged in front of the big rotary wheel. A base plate block is fixedly mounted at the left end of the workbench. The upper front end and the rear end of the base plate block are both provided with limiting blocks. A square sleeve is welded to the workbench. According to the pipe bending machine, the incomplete gear is alternately engaged with the rack and the transmission gear so that the pipe bending machine can make a flat aluminum plate equidistantly slip leftwards at regular time and make the lifting bending frame slip upwards to bend the aluminum plate alternately; and then the flat aluminum plate can be bent by 90 degrees for three times to form the shape of the square aluminum pipe.

Description

technical field [0001] The invention relates to a machining equipment, in particular to a pipe bending machine for manufacturing square aluminum pipes. Background technique [0002] Aluminum tube is a kind of non-ferrous metal tube, which refers to a metal tubular material that is hollow along its longitudinal length through extrusion processing of pure aluminum or aluminum alloy. In some application fields, aluminum tubes are often made into square shapes. Under normal conditions, the fastest way to manufacture square aluminum tubes is to bend a rectangular and long and narrow aluminum plate three times at 90 degrees equidistant along the width of the aluminum plate to form a square shape. The shape of the aluminum tube can be welded at the head-to-tail joint at the end, but it is difficult for the traditional bending machine to shape the shape of the square aluminum tube by bending. Contents of the invention [0003] In order to solve the problem that the shape of the s...
