Abstract
The invention discloses a processing method for an automobile fender. The processing method for the automobile fender comprises the following steps: heating a steel plate, putting the heated steel plate in a metal mould, stamping the steel plate at 635 DEG C, and cooling the stamped steel plate under a closed environment. The steel plate comprises the chemical components in parts by weight: 5.5 parts of carbon, 120 parts of silicon, 58 parts of manganese, 4.5 parts of phosphorus, 0.32 part of sulfur, 1.53 parts of thallium, 0.04 part of boron and 1.61 parts of nickel. According to the processing method for the automobile fender, the purpose of improving the security strength of an automobile is achieved.
Description
Technical field
The present invention relates to automobile manufacture field, particularly, relate to a kind of processing method of fender.
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 processing method of fender, to realize the advantage improving automotive safety intensity.
For achieving the above object, the technical solution used in the present invention is:
A processing method for fender,
After steel plate is heated, put into metal die, under the hot conditions of 635 DEG C, carry out punching press, then cool under closed environment,
The mass parts of described steel plate chemical composition comprises: carbon: 5.5 parts, silicon: 120 parts, manganese: 58 parts, phosphorus: 4.5 parts, sulphur: 0.32 part, thallium; 1.53 parts, boron: 0.04 part, nickel: 1.61 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.
Detailed description of the invention
A processing method for fender,
After steel plate is heated, put into metal die, under the hot conditions of 635 DEG C, carry out punching press, then cool under closed environment,
The mass parts of steel plate chemical composition comprises: carbon: 5.5 parts, silicon: 120 parts, manganese: 58 parts, phosphorus: 4.5 parts, sulphur: 0.32 part, thallium; 1.53 parts, boron: 0.04 part, nickel: 1.61 parts.
