Embodiment: existing detailed in conjunction with the accompanying drawings lock is stated embodiments of the invention.As accompanying drawing 9, Figure 10, Figure 11, Figure 12 and shown in Figure 14, punching and the process of accepting the button grain are: the first, and load onto punch die and adjust the slider of punch stroke; The second, accept cartridge in the punch die counterdie button of packing into, every supporting extend neck (18) is all underlined to be used to take up certain functional symbol button, will notice when packing into that each the functional symbol button that gets off with punching is corresponding one by one; The 3rd, put resistance plug (available sponge or other elastomers are made) in die core rod (31) punching, make it be lower than the about button height of die face, be beneficial to prevent that the button that punching is got off from rolling and unordered whereabouts; The 4th, put the button moulding above counterdie, punching is cut off and is separated moulding button grain and running channel; The 5th, take out the running channel leftover pieces; Repeat to accept tube or reach the setting quantitative requirement by the 4th, the 5th liang of step cycle later on until filling.The key that realizes said process is by punch die and accepts cartridge.Punch die can be produced the manufacturing of moulding actual design according to injection moulding, general punch die adopts standard die set, punch core rod (35) is installed in conjunction with other parts and constitutes the part of the upper die under the cope match-plate pattern (36), die core rod (31) is installed in lower bolster (32) in conjunction with other parts and goes up the formation part of the lower die, the counterdie below is equipped with and is accepted cartridge orifice plate (33), locate by alignment pin (37), align with die core rod (31) punching and engage accepting tube (18), bottom have one flat plate (30) utilize before and after two double-threaded screws (34) and nut check hold and accept tube (18), fall in case accept tube (18).Accept tube (18) and can accept the button that punching is got off in an orderly manner by the cushioning effect of resistance plug in each, it is generally square tubular, sees shown in Figure 13: length L=button grain height h * design will be adorned quantity at every turn, be generally 200mm to 300mm and be advisable; Accept interior length of side a=button maximum length+a 0.4~0.6mm; Accept interior hem width b=button Breadth Maximum+a 0.4~0.6mm, accepting an interior hole dimension has 0.2~0.3mm gap to be advisable all around after putting into button; Accept the size of tube outer length of side A, wide B and determine with following 2 to be foundation: 1, less as more regular arrangement of keys of computer and spacing, it is the same with corresponding face-piece key hole centre-to-centre spacing two-phase to be faced accept (a 18) amalgamation to be plugged in when accepting in cylinder base plate (1912) groove centre-to-centre spacing; 2, bigger to part irregular alignment and spacing, get A=a+2mm, B=b+2mm.In a word, make during design as far as possible and can constitute an integral body when accepting tube (18) amalgamation and conveniently be plugged in and accept in cylinder base plate (1912) groove.As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and shown in Figure 14, button discharging and assembling process are: first, button discharging device (19) is installed on the button assembly machine, adjust button assembly machine lower plate (16), itself and the about 5cm of upper plate (12) distance are advisable, adjust upper plate (12) the spacing adjustment screw (29) that rises, so that be as the criterion apart from the about half button height of lower flashboard (1910) when the highest by keyed jointing post (1904) rising.The second, from punch die, take out accept tin (18) that the plastic key grain is housed; The 3rd, rearrange to be plugged in and accept in cylinder base plate (1912) groove accepting tube (18) by each functional symbol button desired location requirement in the calculator face-piece; The 4th, take out the resistance plug with taking the photograph son; The 5th, the calculator face-piece is installed in the location notch (available offset plate designs according to various computing device face-piece structure) on the face-piece fixed head (1905), make by keyed jointing post (1904) and can pass through the face-piece key hole smoothly; The 6th, step on foot-driven lever (1), make by keyed jointing post (1904) and rise, catch the plastic key grain; The 7th, left and right directions pushes upper flashboard (1909) and lower flashboard (1910) drops to by on the keyed jointing post (1904) basecoat button grain, a little makes by keyed jointing post (1904) apart from the about button height of lower flashboard (1910) to unclamp foot-driven lever (1), decontrols upper flashboard (1909) and lower flashboard (1910); The 8th, the foot-driven lever that comes up (1) makes by keyed jointing post (1904) and descends with subzonal layer one plastic removal material button, in the calculator face-piece key hole of packing into; The 9th, take out the calculator face-piece.Repeat till racking up the plastic key grain of accepting in the tube (18) by the 5th to the 9th step cycle later on, take out at last and accept tube (18) to be housed to punch die.Realize that above-mentioned button discharging and assembling process key are by button discharging device (19) and button assembly machine.Button discharging device (19) generally is made up of following: eject upper plate (1902) and eject lower plate (1901) with screw (1903) locking, make this two plates fixing and locking by keyed jointing post (1904) and guide pillar (1906) head, two guide pillars (1906) pass face-piece fixed head (1905) and insert pressing plate (1908) and accept in the cylinder base plate (1912), to guarantee by keyed jointing post (1904) each center, hole non-migration when moving up and down.Screw (1907) is locked in two block pressur plates (1908) and accepts below the cylinder base plate (1912), constitute a T-slot, upper flashboard (1909) can be by setting stroke move left and right in T-slot with lower flashboard (1910), when making the stressed and lower flashboard (1910) of upper flashboard (1909) stressed to the right left with hand or with additive method, each hole of two flashboards is over against accepting each hole of cylinder base plate (1912), top plastic key grain will fall under the effect of deadweight smoothly, when eliminating firmly, two flashboards set back under the effect of both sides spring (1911), stagger one and set stroke and block the plastic key grain and stop to fall in relative each hole of two flashboards.The key device machine can utilize four legs (20) to be locked on the work top with screw, base plate (27) is housed on the leg (20), two columns (17) are equipped with on both sides in the middle of the base plate, and lock with nut (26), lower plate (28) and upper plate (12) are on base plate (27), lower plate (28) and upper plate (12) respectively have two holes that axle sleeve (10) is housed to cooperate with column (17), spacing with screw (23) and nut (25) control lower plate (28) and upper plate (12), push rod (9) is equipped with in the below in the middle of the lower plate (28), the axle sleeve (11) that push rod (9) process is mated also passes the workbench face, by adjusting lever (8), connecting rod (7), screw (5), bearing (4), screw (2), behind the foot-driven lever (1), through stepping on of operative employee, lower plate (12) with push rod (9) by the parallel rising of leading of column (17) and push rod (9), upper plate (12) moves on lower plate (28) under spring (22) effect, when upper plate (12) rises, adjust screw (29) and withstand connecting plate (16), then upper plate (12) stops to rise, lower plate (28) continues to rise till spring (22) is compressed to the limit at the effect lower compression spring (22) of push rod power, be equipped with fastening four guide pillars (21) of screw (24) at upper plate (12) two, with the parallel rising of better assurance upper plate, screw (13) is used for the connecting plate of adjusting (16) is locked at column (17), screw (14) is used to accept a locking of the same connecting plate of hurdle back (15) (16) and accepts being locked of cylinder base plate (1912) and connecting plate (16), accepting tube (18) is contained in and accepts in cylinder base plate (1912) groove, middle with accepting hurdle back (a 15) hurdle, nut (3) is used for screw (2) is locked at bearing (4), and nut (6) is used for screw (5) is locked at connecting rod.The present invention realizes by above-mentioned these processes and relevant tool mould, machinery exactly.
