Preheating annular cutting device for aluminum-plastic composite pipe

Abstract

The invention relates to the field of aluminum-plastic composite pipe production, in particular to a preheating annular cutting device for an aluminum-plastic composite pipe. The preheating annular cutting device comprises a horizontally arranged supporting installation cylinder, wherein a plurality of rotating installation frames are arranged at the left end of the supporting installation cylinder at equal angles; the rotating installation frames are provided with swinging installation plates leftwards; one ends of the swinging installation plates are connected with the rotating installationframes through resetting rotating shafts, and the other ends of the swinging installation plates are provided with moving guide wheels through driving rotating shafts; and an annular installation plate is arranged at the right end of the supporting installation cylinder. A continuous active guide structure is matched with an elastic adaptive structure, so that the device adapts to cutting operations of aluminum-plastic composite pipes with different pipe diameters; the device has good and accurate annular cutting rotation through a guide rotation structure; the annular cutting is achieved under the matching of a telescopic structure and a rotation structure; and meanwhile an incision after the annular cutting can be sealed in time combined with a preheating structure of the reset rotation,so that the quality of the pipe is guaranteed.

Description

technical field [0001] The invention relates to the field of production of aluminum-plastic composite pipes, in particular to a preheating ring cutting device for aluminum-plastic composite pipes. Background technique [0002] Aluminum-plastic composite pipe has good thermal insulation performance, and the inner and outer walls are not easy to corrode. Because the inner wall is smooth, the resistance to fluid is small; and because it can be bent at will, aluminum-plastic composite pipe is a commonly used thing in life. The manufacture of aluminum-plastic composite pipe is to first fix the aluminum strip roll on the support, pass the aluminum strip through the wide-band cutting mechanism, then pass through the aluminum strip tensioning device, and then pass through multiple sets of round tube preforming molds and round tube forming molds. Fix the end of the aluminum strip to the tractor, adjust the torch head of the welding machine and the wide-band cutting mechanism, so that...

AI Technical Summary

Problems solved by technology

After the aluminum-plastic composite pipe is made, the aluminum-plastic composite pipe will be cut and cut. The inner and outer layers of the aluminum-plastic composite pipe are plastic, and the middle layer is aluminum pipe. After the aluminum-plastic composite pipe is cut, the aluminum-plastic composite pipe will be cut. The pipes are exposed to the outside, and because there is no special adhesive between the three layers of pipes to stick them together, the three layers of pipes will be separated at the cutting place. When the external liquid etc. is immersed between the three layers of pipes, it will affect the quality of the pipe

[0003] Chinese patent (Notice No. CN106737990B) discloses a cutting device for aluminum-plastic composite pipes. Although the above problems can be improved, there are obvious problems in the continuity of the cutting guide, the stability of the cutting, and the sealing quality of the cut. insufficient
