A multi-axis servo controlled high precision erw welded pipe forming mechanism

Abstract

The invention discloses a multi-axis servo control high-precision ERW welding pipe forming mechanism. The multi-axis servo control high-precision ERW welding pipe forming mechanism comprises a base. A square rack is fixed to the top of the base. A vertical guide rail is arranged on a front panel of the rack and is in sliding connection with a roller frame. A longitudinal roller is fixed to the bottom of the roller frame. A roller installing base is arranged at the front portion of the rack, and a horizontal guide rail is horizontally laid in the roller installing base and is in sliding connection with two sliding blocks. The two sliding blocks are arranged on ball screws of two extrusion motors in a sleeving manner correspondingly and can be driven by the extrusion motors to slide on the horizontal guide rail, horizontal rollers are fixed to the tops of the sliding blocks, and the two extrusion motors control the two horizontal rollers to slide along the horizontal guide rail, and accordingly the distance between the two horizontal rollers can be finely adjusted. The two horizontal rollers and the longitudinal roller are arranged in a triangular manner, a gap is formed between the two horizontal rollers and the longitudinal roller, and a pipe blank can stretch in from the gap and is extruded and formed through the horizontal rollers and the longitudinal roller.

Description

technical field [0001] The invention relates to the technical field of pipe production, in particular to a multi-axis servo-controlled high-precision ERW welded pipe forming mechanism and its processing technology. Background technique [0002] The high-frequency tube making machine is a large-scale equipment for mass production of flat tubes for automobile radiators. It is composed of sheet metal unwinding machine, high-frequency controller, forming rollers, shaping rollers, cutters and other important components. [0003] However, there are also many problems in the existing pipe making machines. The position of the rollers of the pipe making machine in the prior art is manually adjusted before the welding power source is started. Human judgment errors lead to the inability to guarantee the welding quality and reduce the work efficiency at the same time. , safe production cannot be guaranteed. At the same time, it will also cause friction between the welded pipe and the r...

Problems solved by technology

[0003] However, there are also many problems in the existing pipe making machines. The position of the rollers of the pipe making machine in the prior art is manually adjusted before the welding power source is started. Human judgment errors lead to the inability to guarantee the welding quality and reduce the work efficiency at the same time. , safe production cannot be guaranteed

At the same time, it will also cause friction between the welded pipe and the roller, resulting in a greater degree of bearing loss of the roller. The friction and wear of the roller is extremely unfavorable to the rolling process, which seriously affects the plastic forming accuracy of the pipe fitting and the life of the mold.
