Embodiment Construction

[0023] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0024] Such as Figure 1 to Figure 3 A tensioner spinning production process is shown, and the specific production process is as follows:

[0025] S1: blanking: blank the cold-drawn seamless steel pipe according to the specified length to obtain the part blank 1;

[0026] S2: Preforming: Clamp the part blank 1 with the upper forming die 2 and the lower forming die 3, and the inner wall of the part blank 1 is closely attached to the outer contour of the upper forming die 2 and the lower forming die 3, and drives the part blank 1 to rotate And the rotation speed is: 500RPM; at this time, the preforming wheel 4 that has been set outside the edge of the part blank 1 is fed radially along the part blank 1, and the feed speed is: 6mm / s, so that the outer surface of the part is i...

Abstract

The invention relates to a tension wheel spinning production process. The tension wheel spinning production process is characterized by comprising the specific production steps of S1, blanking; S2, performing; and S3, forming; in the production process, a seamless steel tube blank with the less breadth is adopted and is attached to the outer contour of a die without leaving a gap; the seamless steel tube blank is subjected to squeezing extension through a performing wheel to form an arc-shaped surface; and a tension wheel is formed through cooperative squeezing extension of a forming wheel andthe die. Compared with the conventional production technology, the tension wheel spinning production process has the advantages that the tension wheel can be formed directly without cutting the edges, raw materials are saved, and waste of cut portions is avoided; and meanwhile, the subsequent cutting procedure is omitted, the technological steps are reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tensioner wheel production, in particular to a tensioner wheel spinning production process. Background technique [0002] In the production of general tensioner, it is processed by seamless steel pipe with thicker wall thickness. The feeding of the outer abrasive tool presses the seamless steel pipe on the surface of the forming mold so that both ends are bent to form a U-shaped structure, and then the protruding block at the bent end is cut to obtain the tensioner structure; [0003] For example, Chinese patent 200910113101.9 discloses a method for forming a controlled flat pulley. In order to solve the problems of large consumables, easy clamping deformation and low production efficiency in the existing processing of flat pulleys, such as Figure 5 , Image 6 shown. In the present invention, the upper forming die and the lower forming die clamp the blank of the tubular part and drive it to rotate, and...
