A car seat side panel and its manufacturing method

Abstract

The invention relates to a side panel of an automobile seat and a manufacturing method thereof. A method for manufacture a side panel of an automobile seat includes a side plate body and a fixing plate, A side panel body is provided with a first folded edge bent downward, At that edge of the fix plate, a second folding edge bent upward is arrange, the fixing plate is positioned at the lower side of one end of the side plate body, the second folding edge of the fix plate is welded to the first folding edge of the side plate body, and the first folding edge is not welded with the fixing plate, and a flanging edge which is folded inwardly is arranged on the first folding edge. As that automobile seat side connecte plate of the invention has high strength and is not easy to deform, the stressof the deformed part of the automobile seat side connecte plate is made to reach the yield limit by punching the sheet metal for many times, and the strength requirement is met; the automobile seat side connecte plate of the automobile seat side connecting plate has high strength and is difficult to deform. By analyzing the temperature change during welding and changing welding sequence and processing conditions, the concentration of welding stress is weakened, the continuity of welding is ensured and deformation is prevented, and the dimensional accuracy is ensured to meet the requirements ofsubsequent assembly.

Description

technical field [0001] The invention relates to an automobile seat side connecting plate and a manufacturing method thereof. Background technique [0002] An important criterion for measuring cars in the market is high safety and low energy consumption. The safety test of cars is carried out by the national testing agency for collision tests. Side collisions are one of the more common forms of car collisions. The number of collisions and the number of injured people are relatively large; this is due to the small deformation and energy-absorbing parts of the side structure of the vehicle body, and the small buffer space. Once a side collision occurs, the probability of occupant injury is relatively high; Reinforcing rods and increasing the thickness of various parts of the seat relatively increase the weight of the vehicle body, and the side plate of the car seat plays this role. [0003] The current car seat side panel includes a side panel body and a fixing plate welded to...

AI Technical Summary

Problems solved by technology

[0004] The sheet metal joints are welded after repeated stamping and deformation. During the welding process, it is found that the deformation after welding is due to the limitation of the structural factors of the weldment. The maximum temperature of the welding zone can reach the boiling of the material for a long time. point, and the temperature drops sharply away from the heat source directly to the greenhouse; this uneven heat input leads to: 1. Uneven temperature change; 2. Uneven plastic change; 3 Uneven phase change; internal stress caused by welding cannot be completely Elimination, resulting in a large deformation of the product after welding, and the final impact difference cannot meet the subsequent assembly requirements; if this deformation is not eliminated, it will also have an adverse effect on the fracture characteristics, fatigue strength and dimensional accuracy of the product structure under certain circumstances
