Abstract
A processing method for slim steel disc, comprises the steps: the first step: provide certain thickness slim steel disc, large area etching is carried out in a side of described slim steel disc and forms large area etching region; Second step: laser generator is provided, described laser generator is utilized to produce the large area etching region of the described slim steel disc of continuous print high energy laser beam irradiation, thus make slim steel disc thermally equivalent to discharge the unnecessary stress in large area etching region to control the flatness of large area etching region, the slim steel disc that the processing method of slim steel disc of the present invention can provide flatness good.
Description
Technical field
The present invention relates to five metals manufacture field, espespecially a kind of processing method of slim steel disc.
Background technology
When sheet metal be worked into very thin after, particularly steel plate, very easily stress is not concentrated and causes pouch-type steel plate deformed, and then affects the flatness problems with respect of pouch-type steel plate.
In mobile communication field, along with the change of the market demand, mobile phone terminal develops to ultrathin gradually, certainly, also need to ensure cylinder block strength while pursuit is ultra-thin, in current ultra thin handset industry, the stainless metal steel disc of general use, as supporting construction, makes while the ultra-thin build of maintenance mobile phone more solid again.But the stress distribution of super-thin steel disc is uneven and cause steel disc flatness problems with respect to become the problem needing most solution.
Summary of the invention
The object of the present invention is to provide the processing method of slim steel disc, enable the flatness structure that slim steel disc keeps good.
For this reason, the invention provides a kind of processing method of slim steel disc, comprise the steps: the first step: certain thickness slim steel disc is provided, large area etching is carried out in a side of described slim steel disc and forms large area etching region; Second step: laser generator is provided, utilize described laser generator to produce the large area etching region of the described slim steel disc of continuous print high energy laser beam irradiation, thus make slim steel disc thermally equivalent to discharge the unnecessary stress in large area etching region to control the flatness of large area etching region.
Relative to prior art, the processing method of the slim steel disc of the present invention irradiates the surface of slim steel disc by laser beam, make slim steel disc thermally equivalent and the stress concentrated on slim steel disc is released, solving the problem that in prior art, slim steel disc flatness is bad.
Accompanying drawing explanation
Fig. 1 is the stereogram of the slim steel disc of the present invention.
Fig. 2 is the schematic diagram of processing method when laser scanning starts of the slim steel disc of the present invention.
Fig. 3 is the schematic diagram of processing method when laser scanning of the slim steel disc of the present invention.
Detailed description of the invention
The processing method of the slim steel disc of the present invention is applicable to the processing of all slim steel discs, but is particularly useful for the slim steel disc in processing mobile phone terminal.
Refer to shown in Fig. 1, Fig. 2, the processing method of slim steel disc of the present invention needs to provide slim steel disc 1 and laser generator 2.The processing method of described slim steel disc 1 is as follows:
The first step: slim steel disc 1 is provided, and slim steel disc 1 punch process is become predetermined shape, described slim steel disc is about 0.4mm, but is not limited to this thickness;
Second step, on the slim steel disc 1 that punching press is good install or weld other spare parts 3(generally by the mode of spot welding);
3rd step, large area etching is carried out in a side of slim steel disc 1 and forms large area etching region 11, etch depth is 0.12mm-0.15mm, is only 0.25mm-0.28mm to avoid mobile phone components and parts to make described slim steel disc 1 at the thickness of this etching region;
Described slim steel disc causes material to lose owing to etching, cause disappearing to the active force of base material, the stress that so hardware stamping produces all concentrates on etching area, forces product harmomegathus product etched back seriously to arch upward, and the flatness of the slim steel disc of aggravation is bad further;
4th step, laser generator 2 is utilized to produce continuous print high energy laser beam 21 with the back side 12 of certain speed longitudinally (direction of A shown in figure) or the horizontal large area etching region 11 of inswept described slim steel disc 1, thus slim steel disc 1 thermally equivalent is reduced to make yield strength, make the stress concentrating on described large area etching region 11 obtain release with the flatness controlling slim steel disc; Described high energy laser beam also can irradiate side, large area etching region 11.
The laser generator 2 of the processing method of the slim steel disc of the present invention can adopt common laser radium carving machine to produce continuous print high energy laser beam; Described laser beam can be with large area etching region described in bar form uniform speed scanning, also can be to produce the laser beam shape equal with large area etching region to irradiate large area etching region certain hour.
The processing method of the slim steel disc of the present invention, for solving the flatness problems with respect of slim steel disc 1, can only adopt above-mentioned 4th step can complete the flatness shaping of slim steel disc 1.
Compared to prior art, the processing method of the slim steel disc of the present invention irradiates the surface of slim steel disc by laser beam, make slim steel disc thermally equivalent and the stress concentrated on slim steel disc is released, solving the problem that in prior art, slim steel disc flatness is bad.
