The process is low in machining cost, good in precision and quality and capable of meeting the national energy-saving and environment-friendly requirements.

Description

technical field [0001] The invention relates to a process for processing load-bearing beams of heavy vehicles. Background technique [0002] The traditional frame load-bearing beam processing technology is mainly realized by large presses and corresponding supporting molds. Its technological process is sheet metal pickling, shearing, mold blanking and punching, and mold forming. Due to the great changes in the product structure of heavy-duty vehicle frame load-bearing beams compared with medium-sized vehicles, the existing punching dies and forming dies cannot be used at all, and the product quality requirements are relatively high, and there are many varieties and small batches. Although traditional processing technology and equipment (presses and molds) have the advantages of high production efficiency and small equipment footprint for the same type of mass production, they also have poor flexible processing capabilities, high mold costs, long production preparation cycle...

AI Technical Summary

Problems solved by technology

Because the heavy-duty vehicle frame load-bearing beam has undergone great changes compared with the medium-sized vehicle product structure, the existing punching dies and forming dies cannot be used at all, and the product quality requirements are relatively high, and there are many varieties and small batches.

Although traditional processing technology and equipment (presses and molds) have the advantages of high production efficiency and small equipment footprint for the same type of mass production, they also have poor flexible processing capabilities, high mold costs, long production preparation cycles, and long mold change times. , low efficiency, some key quality parameters fail to meet the standard requirements, sheet metal pickling pollutes the environment and other shortcomings seriously restrict the capacity and quality of heavy-duty vehicle frame load-bearing beams and become a bottleneck restricting the capacity and quality of heavy-duty vehicles.
