Abstract
The invention discloses a process for machining a seamless shell for USB (universal serial bus) interfaces. The process comprises the steps of flattening coil stocks, cutting belt materials, stretching repeatedly, reshaping a shell, removing the bottom of the shell, punching side holes, and rotatably cutting blanks; and according to the process, through gradually stretching and reshaping pits obtained by punching, a main profile with a seamless wall is formed, then the bottom of the shell obtained by stretching is removed through punching, thereby forming an interface shell with two open ends. According to the invention, a produced shell for USB interfaces is seamless; and the process has the characteristics that production cost is low, material consumption is less, and productivity and efficiency are high.
Description
[technical field]
The present invention relates to a kind of processing of metal shell, particularly a kind of no seam USB interface shell processing technology.
[background technology]
Data transmission interface is a kind of connected mode that communicates between two equipment, and data transmission bauds can receive the influence of interface rate.Under the situation that people increase the transfer of data increasing demand, interfacing has obtained constantly promoting, and interface type demonstrates diversified development trend.In the present interfaces type, USB interface relies on its high speed performance and hot plug function, and gets more and more people's extensive concerning, and is widely used in each field.But all have tangible seam vestige on the metal shell of prior USB interface, it has not only influenced the outward appearance of interface shell, has also reduced the rigidity intensity of housing.Present no seam USB interface shell adopts the processing method production of CNC machine-shaping, and there is the production cost height in this kind processing method, consumable material is many, production capacity is low and inefficient shortcoming.Above-mentioned shortcoming concrete manifestation is following: the single-piece USB interface shell of being produced with this processing method is an example; Its cost reaches 1 yuan/PCS, and consumable material reaches 0.015KG, and the waste material of generation reaches 0.013KG; Average every CNC per hour can only process 60PCS, and on average everyone per hour can only process 60PCS.
[summary of the invention]
The objective of the invention is to: overcome the deficiency of prior art, a kind of no seam USB interface shell processing technology is provided, the interface shell that this processing method is produced does not have seam, and its production cost is low, consumptive material is few, production capacity and efficient high.
Technical scheme of the present invention is achieved in that it comprises following operation:
A, leveling coiled strip: will be with the coil of strip material through the evener leveling, and form smooth band material;
B, band material otch: the strip that will be processed into Rack with material;
C, stretching repeatedly: on strip, stamp out depression, and depression is carried out progressively pull and stretch repeatedly, to form the basic size of product needed gradually;
D, housing shaping: the bottom of the housing that the end that operation C is obtained is uncovered and side shaping make housing meet the requirements of size;
At the bottom of E, the removal shell: remove the housing bottom that step D obtains, form the shell of open at both ends;
F, punching out side opening: punching out perforate in the side of shell;
G, rotary-cut blanking: shell is downcut from the strip rotation, reach the finished size requirement;
In the above-mentioned no seam USB interface shell processing technology, in operation C progressively repeatedly pull and stretch be depression is carried out three times at the beginning of pull and stretch and seven moulding pull and stretch;
In the above-mentioned no seam USB interface shell processing technology, operation E adopts and accomplishes towards the bottom outlet mode;
In the above-mentioned no seam USB interface shell processing technology, behind operation G, shell is carried out polishing;
In the above-mentioned no seam USB interface shell processing technology, band coil of strip material is a stainless steel material.
The present invention adopts punching press to be processed to form the USB interface shell continuously belt steel material, and in the punching course, the main part of USB interface shell is through drawing and forming, so the wall body of shell is continuous.
Beneficial effect of the present invention is: the USB interface shell of being produced does not have seam, and have that production cost is low, consumptive material is few, production capacity and the high characteristics of efficient; Compare with existing process method; The single products processing charges of this processing technology only need 0.30 yuan/PCS, and every product consumable material is 0.005KG, and waste material has only 0.003KG; Average every punch press per hour can be processed 600PCS, and on average everyone per hour can process 600PCS.

Fig. 2 is the generalized section of A-A direction as shown in Figure 1
Among the figure: 1, shell; 2, perforate.
[specific embodiment]
No seam USB interface shell processing technology of the present invention is and the diverse new technology of mode of existing employing CNC machine-shaping that it comprises following operation:
A, leveling coiled strip: prepare band coil of strip material, will be with the coil of strip material, form smooth band material, be convenient to follow-up punching out through the evener leveling; Preferably, band coil of strip material adopts stainless steel material, helps increasing the service life of finished product, avoids being corroded getting rusty and causing losing efficacy.
B, band material otch: the strip that will be processed into Rack with material.
C, stretching repeatedly: on strip, stamp out depression, and depression is carried out progressively repeatedly pull and stretch (drawing), to form the basic size of product needed gradually; In drawing process repeatedly; Pull and stretch at the beginning of earlier depression being carried out three times; The degree of depth progressively to deepen depression forms recessed deeply; Then the appearance profile according to required USB interface stretches to seven moulding of dark recessed row, is that the step material of dark concave portion is shaped to the uncovered housing of an end, and the size of this housing is near required finished size.
D, housing shaping: the bottom of the housing that the end that operation C is obtained is uncovered and side shaping make housing meet the requirements of size;
At the bottom of E, the removal shell: remove the housing bottom that step D obtains, adopt and accomplish the die-cut of housing bottom, form the shell 1 (as depicted in figs. 1 and 2) of open at both ends towards the bottom outlet mode;
F, punching out side opening: punching out perforate 2 (as shown in Figure 2) in the side of shell;
G, rotary-cut blanking:,, reach the finished size requirement so must shell 1 be downcut from the strip rotation along uncovered edge on the shell because of the last opening end of shell still is connected on the strip.
Further, can behind operation G, carry out polishing, form final finished shell.
Described above be merely preferred embodiment of the present invention, above-mentioned specific embodiment is not a limitation of the present invention.In technological thought category of the present invention, various distortion and modification can appear, and the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, the scope that all belongs to the present invention and protected.
