System and method for processing automobile door-ring tailor-welded plate blanks

Abstract

The invention discloses a system and method for processing automobile door-ring tailor-welded plate blanks. The processing system comprises a discharging mechanism, a plurality of articulated manipulators, a plurality of plate tool clamps, a moving mechanism, a laser cutting mechanism and a laser welding mechanism, wherein a plurality of plates discharged by the discharging mechanism are providedwith cutting parts; the plates are positioned on the plate tool clamps; the parts to be cut of the plates are suspended outside the plate tool clamps; a laser cutting head of the laser cutting mechanism and a laser welding head of the laser welding mechanism are correspondingly arranged on the moving mechanism; the moving mechanism drives the laser cutting head to sequentially cut off each part tobe cut so that each plate can form a welding plate edge; each articulated manipulator can drive the corresponding plate tool clamps on the articulated manipulator to move in a horizontal direction sothat the welding plate edges of each two adjacent plates correspondingly abut to form a welding portion; and the moving mechanism drives the laser welding head to sequentially weld each welding portion. The system and the method have the advantages of high production efficiency, low tooling cost, high welding quality and the like.

Description

technical field [0001] The invention relates to the technical field of automobile parts processing, in particular to a processing system and method for an automobile door ring tailor welded blank blank. Background technique [0002] In the automotive industry, laser tailor welding is usually used to assemble and weld steel materials of different materials and thicknesses to meet the needs of different strengths in different regions of a part. Tailored welded blanks can not only reduce the manufacturing cost, vehicle weight, fuel consumption and scrap rate of the vehicle, but also reduce the number of peripheral reinforcements, simplify the assembly steps, and improve the vehicle's collision ability, stamping rate and corrosion resistance, so Bring huge economic benefits to the automobile manufacturing industry. [0003] Especially on the high-strength steel hot-formed car door ring, the laser tailor welding process greatly improves the material utilization rate and further ...

AI Technical Summary

Problems solved by technology

[0006] 2. Each type of car door knocker needs to invest in a complete set of fixtures, which is costly

[0007] 3. Each sheet undergoes pre-positioning of positioning pins, support adsorption and clamping plate clamping and positioning in sequence, and the last seam needs to move the sheet to fit the weld. This process sequence is inefficient and the production capacity is greatly limited.
