Assembled welding part and machining method thereof

Abstract

The invention discloses a machining method of an assembled welding part. The machining method is characterized by specifically comprising the following steps that S1, pipe cutting is conducted, specifically, a technician machines materials into a first 45-degree oblique angle pipe, a second 45-degree oblique angle pipe and a third right-angle pipe through a laser cutting machine; s2, pipe machining is conducted, specifically, an inverted trapezoidal groove is cut in the middle of the bevel edge of the first pipe through a laser cutting machine, a first rectangular groove is cut in the same side of the groove, an inverted trapezoidal protrusion is cut in the middle of the bevel edge of the second pipe, a second rectangular groove is cut in the same side of the protrusion, and rectangular protrusions are arranged on the two perpendicular sides of a third right-angle pipe correspondingly; the inverted trapezoidal groove and the inverted trapezoidal protrusion can be embedded, the first rectangular groove and the second rectangular groove can be embedded with the rectangular protrusion respectively, and the problems of poor welding and unattractive welding are solved through assembling, welding and the like.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to an assembled welding piece and a processing method thereof. Background technique [0002] The consistency of the pipes in the market is poor (the external dimension tolerance is ±0.5mm), so there are problems such as large welding seams, poor welding or unsightly welding after being cut into semi-finished products by a laser cutting machine. At the same time, the original structure of the product adopts drilling and subsequent rivet installation Positioning, the process is cumbersome, time-consuming, labor-intensive and costly; for this reason, we consider whether the accuracy and stability of the finished product can be improved through the improvement of the assembly form and process. SUMMARY OF THE INVENTION [0003] In order to solve the problems mentioned in the background art, the present invention discloses a processing method of an assembled welded part, which s...

[0002] The consistency of pipes in the market is poor (dimension tolerance is ±0.5mm), so there are problems such as large weld seam, poor welding or unsightly welding after being cut into semi-finished products by laser cutting machine. At the same time, the original structure of the product adopts punching and subsequent installation of rivets Positioning, cumbersome process, time-consuming, labor-intensive and cost-intensive; for this reason, we think about whether the accuracy and stability of the finished product can be improved through the improvement of the assembly form and process
