P-shaped pipe, P-shaped pipe forming process and P-shaped pipe forming equipment

Abstract

The invention provides a P-shaped pipe, a P-shaped pipe forming process and P-shaped pipe forming equipment and relates to the technical field of refrigerating equipment. The P-shaped pipe comprises awide cavity part and a narrow cavity part. The wide cavity part and the narrow cavity part are distributed along the width direction of the P-shaped pipe and are integrally formed, and a piece is arranged on the end surface of the side, far away from the narrow cavity part, of the wide cavity part and stretches along the length of the P-shaped pipe. The P-shaped pipe is manufactured at one time by means of the P-shaped pipe forming process adopting a roll forming technology, and the piece is located on the side wall, far away from the narrow end, of the P-shaped pipe. The P-shaped forming equipment comprises a plurality of groups of forming rollers. Each group of forming rollers comprises an upper guide roller and a lower guide roller arranged oppositely up and down. The P-shaped pipe issimple in structure and free of welding, so that the manufacturing process is cut down. The P-shaped pipe forming process can form the P-shaped pipe directly at one time, so that the shape structure and the curvature of the P-shaped pipe are ensured, the assembling property of the P-shaped pipe is improved, and the production efficiency is improved. The P-shaped pipe forming equipment is low in manufacturing cost, rapid to form and convenient to operate and maintain.

Description

Technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a P-shaped tube, a P-shaped tube forming process and a P-shaped tube forming device. Background technique [0002] High-strength P-shaped tubes are commonly used as structural reinforcements on refrigerators. figure 1 It is a sectional view of the P-shaped tube in the prior art; figure 2 It is a schematic diagram of the installation of the P-shaped tube in the refrigerator in the prior art; image 3 It is the production flow chart of the P-shaped tube in the prior art. In the prior art, the P-shaped tube for this purpose has a cross-section like figure 1 As shown, its use place is like figure 2 As shown, the production process is as image 3 Shown. [0003] Such as figure 1 , 3 As shown, the seam 3 (before welding) of the P-shaped tube is arranged on the upper surface with the largest plane area, and the seam 3 thus arranged is convenient for stamping and welding. And...
