Problems solved by technology

Furthermore, because the manufacturing process of frame longitudinal beam products is limited by the overall process layout (ie: the longitudinal beam sheet is first cut and blanked by CNC → punching → shape modification or gas cutting modification → bending forming or stamping forming process )
For example, after the longitudinal beam is formed, the height difference between the upper and lower airfoils is used to modify the shape. The longitudinal beam modification process area is divided into two parts: the longitudinal beam loading process area and the longitudinal beam unloading process area, which occupy a large space.
The hanging tools used for loading and unloading are cranes or suction cups. This process can meet the product quality and is not conducive to the layout requirements of the company's entire site.

Embodiment Construction

[0016] The invention discloses a method for positioning and trimming the straight-through vehicle frame longitudinal beam sheet material by means of bolts. After the straight-through vehicle frame longitudinal beam sheet material is punched, the stacked sheet material is hung on the material platform of the profiling shear bed. Then push the sheet material to the cutting edge position of the shearing machine according to the slideway of the material rack, respectively align the modification process holes of the front and rear parts of the sheet material with the positioning process holes of the table top of the shearing machine, insert and fix it with the pin, and copy the trimming sheet One side of the material; drag away from the scissors mouth to the pneumatic flip position, flip the piece, and then push the piece to the cutting edge of the shearing machine, repeat the above action to achieve the other side of the profiling shear. The technological method of modifying and lo...

Abstract

The invention discloses a shaping process method of a straight-through frame longitudinal beam plate positioning profiling shear. An original process mode of a scribing or profiling shear is changed.The shaping method of the positioning profiling shear for a frame longitudinal beam plate is improved, so that the phenomena of improper trimming height difference of a longitudinal beam sheet deformation area and front-back dislocation of an inflection point are prevented, the control requirements of the product procedure quality are improved, and meanwhile, the part production efficiency is improved.

Description

technical field [0001] The invention relates to a method for modifying the shape of a straight-through frame longitudinal beam sheet material, in particular to a shape modification process method for the straight-through frame longitudinal beam sheet material positioning profiling shears. Background technique [0002] At present, for small and medium-sized auto parts and frame assembly processing enterprises, the production process and process of frame longitudinal beams play a decisive role in the entire production cycle by controlling the process quality of products. In order to ensure that the height difference of the upper and lower airfoils and the matching of the deformation zone behind the inner and outer longitudinal beams of the frame meet the product quality requirements. Furthermore, because the manufacturing process of frame longitudinal beam products is limited by the overall process layout (ie: the longitudinal beam sheet is first CNC sheared and blanked → punc...
