Problems solved by technology

[0002] At present, when it is required to process square tubes with arcs, the assembly method is often used for processing, and the joints are welded. This method is not only labor-intensive and material-intensive, but also the welding point is also the stress concentration point of the angled square tube. It is easy to reach the fatigue point due to long-term stress, and it is easy to crack

Embodiment Construction

[0011] Combine below figure 1 The embodiment of the present invention is further described: a square tube arc rolling equipment includes: a sliding sleeve (1), an upper shaft (2), a lower shaft (3), and a pressure roller (4). The lower shaft (3) is fixed on the frame (5) by the bearing; the upper shaft (2) is installed on the sliding sleeve (1) through the bearing, and the sliding sleeve (1) controls the upper shaft (2) to move up and down; the upper shaft (2) 1. A pressure roller (4) is installed on the same-side shaft end of the lower shaft (3), and the outer surface of the pressure roller (4) is processed with a groove, which is suitable for the width of the square tube processed with an arc, and the square tube is controlled by the pressure roller In (4), it rotates with the rotation of the shaft, so as to realize the purpose of rolling the square tube into a circular arc.

[0012] The working principle of a square tube arc rolling equipment is: the groove width of the pr...

Abstract

The invention discloses circular arc rolling equipment for square pipes. The circular arc rolling equipment comprises a sliding sleeve, an upper shaft, a lower shaft and pressing rollers. The lower shaft is fixed to a frame through a bearing. The upper shaft is installed on the sliding sleeve through a bearing. The sliding sleeve controls the upper shaft to move up and down. The pressing rollers are installed at the shaft ends of the same side of the upper shaft and the lower shaft correspondingly. A groove is machined in the outer surface of each pressing roller. The grooves are matched with the widths of the circular-arc-machined square pipes correspondingly. The square pipes are controlled in the pressing rollers correspondingly and rotate along with rotation of the shafts, and thus the purpose that circular arcs are formed on the square pipes in a rolled mode is achieved. Through the circular arc rolling equipment, manual operation can be reduced effectively, and cracks liable to occur due to assembly welding are avoided. The sizes of the machined square pipes with radians are regular, and the radian uniformity is good.

Description

technical field [0001] The invention relates to a special equipment for rolling processing, in particular to a square tube arc rolling equipment. Background technique [0002] At present, when it is required to process square tubes with arcs, the assembly method is often used for processing, and the joints are welded. This method is not only labor-intensive and material-intensive, but also the welding point is also the stress concentration point of the angled square tube. It is easy to reach the fatigue point due to long-term stress, and it is easy to crack. Contents of the invention [0003] In view of the above-mentioned technical problems, the purpose of the present invention is to provide a convenient, fast and durable equipment that can meet the requirements of processed products. [0004] The technical solution adopted in the present invention is: a square tube arc rolling equipment comprising: a sliding sleeve, an upper shaft, a lower shaft, and a pressing roller. ...
