Barbell bar extruded by retaining ring

Abstract

The invention relates to a barbell bar formed by check rings in an extruding mode. The barbell bar comprises a metal tubular product and the check rings. The check rings are distributed on the two sides of the metal tubular product in the mode that the check rings are perpendicular to the metal tubular product and are used for installing barbell bodies, and the check rings are formed by bending the pipe wall of the metal tubular product towards the outer side. According to the barbell bar formed by the check rings in the extruding mode, barbell bar forming machining has the advantages of being simple in procedure, low in power consumption, free of welding, harmless to human bodies, free of material waste and the like.

Description

technical field [0001] The invention belongs to the technical field of barbell bar processing and molding, and in particular relates to a barbell bar extruded and formed by retaining rings. Background technique [0002] Barbells are currently mainly made of metal pipes welded with metal retaining rings, and are widely used in sports, home fitness equipment and other fields. as attached figure 1 and 2 As shown, the general barbell bar is blanked by metal pipe ( figure 2 Shown in 2-2), knurling on the surface of the steel pipe 1 ( figure 2 shown in 2-3), stamping equipment punching, blanking processing into retaining ring 2 ( figure 2 shown in 2-1), and finally weld the above-mentioned processed retaining ring 2 at the welding point 3 to process the above-mentioned processed metal pipe ( figure 2 2-4 in). However, the metal pipe welding metal retaining ring 2 process is more complicated, the raw material processing and final forming welding process is time-consuming,...

AI Technical Summary

Problems solved by technology

However, the metal pipe welding metal retaining ring 2 process is more complicated, the raw material processing and final forming welding process is time-consuming, energy consumption is high, and metal welding is more harmful to the human body, and welding is prone to welding slag, penetration, and false welding. Defects, especially false welding, pose a huge potential threat to human life

[0003] In addition, with the rising price of metal materials, it is more and more important to increase the utilization rate of materials. However, the materials of metal welded retaining rings need complex procedures such as punching and blanking, and the material utilization rate is also very low.
