Automatic pipe bending machine for spiral tube

Abstract

The invention discloses an automatic pipe bending machine for a spiral tube. The automatic pipe bending machine comprises a driving spiral pipe bending die provided with a pipe bending spiral groove;one end of the driving spiral pipe bending die is mounted on a machine frame through a bearing seat, and connected with a motor through a speed reducer, a pipe clamping device is mounted at the otherend of the driving spiral pipe bending die, and a driven spiral pipe bending die parallel to the driving spiral pipe bending die is mounted on one side of the driving spiral pipe bending die; and a guiding spiral groove with respect to the pipe bending spiral groove is formed in the driven spiral pipe bending die, a driven synchronizer gear is mounted on the driven spiral pipe bending die, the driven synchronizer gear is in transmission meshed with a driving gear mounted on the driving spiral pipe bending die, a limiting sensing switch for detecting the being in place of the spiral tube is mounted on the machine frame, and the motor and the limiting sensing switch are electrically connected with a control box. Compared with the prior art, the spacing consistency of the spiral tube is high,the labor intensity of the operators is low, one operator can process more than 200 spiral tubes in one day, the work efficiency is greatly improved, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an automatic pipe bending machine for spiral pipes. Background technique [0002] The coiled tube used in the automobile pipeline system is in a spiral coiled state, and is made of stainless steel tube. The diameter of the stainless steel tube is Φ15~Φ18mm, the wall thickness is 1.5mm, and the number of spiral turns of the coiled tube is 7. The automatic pipe bending machine currently used fails to realize the bending of the spiral pipe, and the stainless steel pipe can only be bent into a spiral pipe by manually using the pipe bending fixture. During the pipe bending process, the helical pitch of the coiled tube is difficult to control, and the helical pitch of the produced coiled tube has poor consistency; usually, it takes three operators to work together to complete the processing of 50-60 coiled tubes in one day, and the labor intensity of the operators is high...
