A device for shaping high-precision automotive door sill reinforcements

Abstract

The invention discloses a high-accuracy device for shaping an automobile threshold reinforcing element. The high-accuracy device for shaping the automobile threshold reinforcing element comprises a bottom table, a conveying belt and burr detection devices, wherein the conveying belt is fixedly installed om the bottom table, and the threshold reinforcing element is placed on the conveying belt; twoburr detection devices are arranged, and installed on the bottom table in the form of symmetrical distribution; two drive elements are fixed to the bottom of the bottom table in the form of symmetrical distribution; and the two ends of each drive element are fixed to one end of each of the two burr detection devices separately. According to the high-accuracy device for shaping the automobile threshold reinforcing element, the reinforcing element is placed on the conveying belt, and the movement of the reinforcing element is driven through the conveying belt; meanwhile, a metal wire is bondedonto the surface of the top of the reinforcing element, when burrs exist at a through hole in the top of the reinforcing element, the metal wire is pulled, so that automatic detection for the burrs isrealized; and compared with the traditional palm touch and visual inspection, labor is not needed in the detection, and high detection efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of shaping of automotive door sill reinforcements, in particular to a device for shaping high-precision automotive sill reinforcements. Background technique [0002] The door sill is a high-strength structural part of the whole vehicle. Its function is to absorb and slow down the side impact force, protect the body structure, reduce the injury to the passengers in the collision accident, and improve the safety of the whole vehicle. The strength and processing quality of the door sill material The requirements are also getting higher and higher. Roll forming has high production efficiency, good product surface quality, continuous production and can integrate other processing technologies. The process of producing threshold reinforcement plates is: online punching → roll forming → back punching (punching Cutting flange edge + punching + pressing) → Rolling to fixed length cutting, some holes and process gaps o...

Problems solved by technology

[0002] As a high-strength structural part of the whole vehicle, the threshold is to absorb and slow down the side impact force, protect the body structure, reduce the damage to the passengers in the collision accident, improve the safety of the vehicle, the strength and processing quality of the threshold material The requirements are getting higher and higher. Roll forming has high production efficiency, good product surface quality, continuous production and can integrate other processing technologies. The process of producing door sill reinforcement plates is: online punching→roll forming→back punching (punching Flange edge cutting + punching + profiling) → roll pressing and cutting to length. The upper part of the existing automobile door sill reinforcement and the process gap are punched online, and the flange edge gap is completed by back punching. After the online punching, It is inevitable that there will be some defects such as burrs. If the burrs are large, it will affect the subsequent roll forming. During roll forming, the product will easily form defects such as wrinkles and curling, which will affect the subsequent quality.

After the backflushing, if the burrs are large, the parts will not be installed tightly and cannot meet the high precision requirements

[0003] At present, burr detection is generally based on visual inspection and touch method. Glitch detection is carried out through personnel's eye observation and palm touch. However, this kind of detection takes a long time and cannot detect burrs efficiently and conveniently. Therefore, we propose a high-precision automotive threshold enhancement. device for shaping
