Abstract
The invention discloses a machining method of reinforcing ribs of an automobile ceiling. A steel plate is placed into a metal die after being heated, the stamping is performed under the high temperature of 825 DEG C, and the cooling is performed in a closed environment, wherein the steel plate comprises chemical composition of, by mass, 9 parts of carbon, 125 parts of silicon, 65 parts of manganese, 2.5 parts of phosphorus, 0.21 part of sulfur, 1.58 parts of thallium, 0.04 part of boron and 2.5 parts of nickel. According to the machining method of the reinforcing ribs of the automobile ceiling, the safety strength of an automobile can be improved.
Description
Technical field
The present invention relates to automobile manufacture field, particularly, relate to a kind of processing method of roof of the vehicle reinforcement.
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 roof of the vehicle reinforcement, 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 roof of the vehicle reinforcement,
After steel plate is heated, put into metal die, under the hot conditions of 825 DEG C, carry out punching press, then cool under closed environment,
The mass parts of described steel plate chemical composition comprises: carbon: 9 parts, silicon: 125 parts, manganese: 65 parts, phosphorus: 2.5 parts, sulphur: 0.21 part, thallium; 1.58 parts, boron: 0.04 part, nickel: 2.5 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.
Detailed description of the invention
A processing method for roof of the vehicle reinforcement,
After steel plate is heated, put into metal die, under the hot conditions of 825 DEG C, carry out punching press, then cool under closed environment,
The mass parts of steel plate chemical composition comprises: carbon: 9 parts, silicon: 125 parts, manganese: 65 parts, phosphorus: 2.5 parts, sulphur: 0.21 part, thallium; 1.58 parts, boron: 0.04 part, nickel: 2.5 parts.
Gallium 0.06 part is also added, chromium 15 parts in steel plate.Other is iron and a small amount of impurity.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
