What is a thermoformed steel plate body part?

(初始强度为500~600MPa)加热至奥氏体化状态,快速转移到模具中高速冲压成形,在保证一定压力的情况下,制件在模具本体中以大于27℃/s的冷却速度进行淬火处理,保压淬火一段时间,以获得具有均匀马氏体组织的超高强钢零件(1300-1600Mpa)。 The boron steel plate (initial strength is 500 ~ 600MPa) is heated to austenitizing state, and it is quickly transferred to the mold for high-speed stamping. Under the condition of ensuring a certain pressure, the product is in the mold body with a The cooling rate is quenched and pressure-quenched for a period of time to obtain ultra-high-strength steel parts (1300-1600Mpa) with a uniform martensitic structure.

Why use hot formed steel body parts?

Extremely high material strength and ductility. 400-450MPa左右,而热成形钢材加热前抗拉强度就已达到500-800 MPa,加热成形后则提高至1300-1600 MPa。 The tensile strength of general high-strength steel plates is about 400-450 MPa, while the tensile strength of hot-formed steels has reached 500-800 MPa before heating, and increased to 1300-1600 MPa after heating forming. Therefore, the body made of hot-formed steel sheet greatly improves the collision resistance and overall safety of the vehicle body, and will play a good role in protecting people in the vehicle during a collision.

Effectively reduce vehicle weight and save energy consumption. Due to the extremely high material strength of the hot-formed steel sheet, one hot-formed part can be used in the design to replace the parts of multiple ordinary steel sheets. A柱加强版、B柱加强版、地板部件、前端等,可为汽车提高安全性,减轻重量。 This kind of part has thin thickness, light weight and high strength, and has less rebound resilience than cold stamping. It is suitable for manufacturing A-pillar reinforced version, B-pillar reinforced version, floor parts, front end, etc., which can improve safety and reduce weight for automobiles.

Talking about the welding process of automotive nut spot welder

Today, the editor of Rong Shijie explained the welding process of spot welding machines for automotive nuts: nut bump welding is a deformation of bump welding. Generally, bumps are punched out on one of two parts and then welded. Due to the current concentration, the shortcomings of nugget translation during bump welding are overcome, so the thickness ratio of the workpiece during projection welding can exceed 6: 1. During projection welding, the current must drop rapidly as the bumps are crushed, otherwise it will cause splashing due to pressure loss, so a bump with good followability of the electrode should be used ...

What equipment does a complete welding robot workstation include?

What is the difference between a welding robot and a welding robot workstation? The editor of Rong Shijie tells you that a general welding robot refers to a set of machines, mainly composed of a robot assembly, control system, education system, welding machine, wire feeding mechanism, welding gun, etc. composition. In addition to the welding robot workstation, the welding robot workstation also includes a lot of auxiliary equipment such as ground rails, positioners, flip tables, weld tracking systems, safety fences, gun cleaners, safety systems, peripheral equipment ...
