Abstract

The present invention discloses an automobile A column reinforcing plate processing method. A steel plate is put into a metal die after being heated, then is punched under a 660 DEG C high temperature condition, and is cooled in a closed environment. The steel plate comprises the following chemical components by mass, 5 parts of carbon, 100 parts of silicon, 50 parts of manganese, 5 parts of phosphorus, 0.8 parts of sulphur, 1.1 parts of thallium, 0.04 parts of boron, and 1.5 parts of nickel. The purpose of improving automobile safety strength is achieved.

Description

Automobile A column stiffener processing method

Technical field

The present invention relates to automobile manufacture field, particularly, relate to a kind of automobile A column stiffener processing method.

Background technology

At present, automobile is in the period of develop rapidly, people are also improving constantly the requirement of automotive safety, although automotive safety relates to the design of Integral automobile structure, but automobile steel still play important effect to safety, existing automobile steel material often adopts hot strength to mark the intensity of steel, but high its yield strength of steel of many hot strengths does not reach safety requirements under strong collision, thus makes many automobile part security intensities inadequate.

Summary of the invention

The object of the invention is to, for the problems referred to above, propose a kind of automobile A column stiffener processing method, to realize the advantage improving automotive safety intensity.

For achieving the above object, the technical solution used in the present invention is:

A kind of automobile A column stiffener processing method,

After steel plate is heated, put into metal die, under the hot conditions of 660 DEG C, carry out punching press, then cool under closed environment,

The mass parts of described steel plate chemical composition comprises: carbon: 5 parts, silicon: 100 parts, manganese: 50 parts, phosphorus: 5 parts, sulphur: 0.8 part, thallium; 1.1 parts, boron: 0.04 part, nickel: 1.5 parts.

Technical scheme of the present invention has following beneficial effect:

Technical scheme of the present invention, adds the compositions such as manganese, nickel and thallium in steel plate, thus increases the yield strength of steel plate, reaches the object improving automotive safety intensity.
