The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Referring to figs. 1 through Fig. 3, the utility model embodiment provides a kind of aluminum alloy pattern plate hole punched device, comprise the workbench 14 that workpiece 16 both sides are provided with, workbench 14 is for clamping and unclamp workpiece 16, inner side at workbench 14 is provided with idler wheel mechanism, and for the slip of workpiece 16, described idler wheel mechanism comprises a liter wheel cylinder 18, rise on wheel cylinder 18 rolling wheel support 17 is set, on rolling wheel support 17, be provided with roller 15; In the outside of workbench 14, all connect little frame 6, workbench 14 is all arranged on base 61 with little frame 6, at base 61, be arranged with transverse-moving mechanism 4, transverse-moving mechanism 4 comprises slide rail 5, base 61 is not shown in FIG. by clamping cylinder 21() effect, on slide rail 5, do transverse movement, thereby drive the transverse movement of workbench 14 and little frame 6.Transverse-moving mechanism 4 is arranged on platform 3, and platform 3 belows are frame 2, and frame 2 is supported by pin cup 1.
In little frame 6, be provided with long guideway base 7, on long guideway base 7, be provided with ball-screw 9, ball-screw 9 is fixing by leading screw holder 8, in the both sides of leading screw holder 8, be equipped with long guideway 10, on long guideway 10 and leading screw holder 8, be connected with sliding seat 11, sliding seat 11 travels longitudinally on long guideway 10 by ball-screw 9; On sliding seat 11, be provided with and move back mould slide rail 19; move back on mould slide rail 19 and connect punch mechanism; punch mechanism is by moving back the effect of mould cylinder 20; do transverse movement moving back on mould slide rail 19; punch mechanism comprises hydraulic cylinder 12 and diel 13; the two sides of workpiece 16 snap in respectively in diel 13, and punch mechanism carries out punching action to the two sides of workpiece 16.Because the ball-screw 9 adopting has, positioning precision is high, transmission efficiency is high, high life, makes the punching station of workpiece 16 up to specification, and precision is higher.
At the utility model embodiment, also provide a kind of hole-punching method that uses above-mentioned aluminum alloy pattern plate hole punched device, comprised the following steps:
(1) workpiece 16 enters after workbench 14, rising wheel cylinder 18 drives roller 15 to rise by rolling wheel support 17, ball-screw 9 drives punch mechanism to move on long guideway 10, preferably ball-screw 9 is driven by servomotor, the two sides of workpiece 16 are snapped in respectively in diel 13, then by moving back the past both sides transverse movement of mould cylinder 20, diel 13 clamping work pieces, ball-screw 9 and long guideway 10 drive punch mechanism to move forward, workpiece 16 are placed in to the position of processing;
(2) clamping cylinder 21 drives work piece platform 14 toward intermediate lateral motion, clamping work pieces, and ball-screw 9 drives punch mechanism to move backward to first position, hole, and punch mechanism is gone out first hole; Then, ball-screw 9 drives punch mechanism to move backward to position, second hole, and punch mechanism is gone out second hole; So repeat, until go out the hole of all settings.
(3) last, clamping cylinder 21 drives work piece platform 14 toward both sides transverse movement, and workpiece comes loose;
(4) next workpiece enters workbench 14, ball-screw 9 and long guideway 10 drive punch mechanism to move, the two sides of next workpiece are snapped in respectively in diel 13, then by moving back the past both sides transverse movement of mould cylinder 20, diel 13 clamping work pieces, ball-screw 9 and long guideway 10 drive punch mechanism to move forward, next workpiece are placed in to the position of processing, now workpiece before 16 are gone out to aluminum alloy pattern plate hole punched device.
As preferably, this aluminum alloy pattern plate hole punched device comprises central computer, by central computer input hole position and hole column pitch from machined parameters, automatically detect the position of workpiece 16, workpiece 16 automatic feeds, then carry out punching according to Wei He hole, the hole column pitch of setting.By central computer, set up simple and convenient man-machine interface, ordinary person is just trained a little can parameters, in this device fabrication process, without employee's operation, realizes automation completely, and the positional precision in hole is high.
As can be seen from the above description, the aluminum alloy pattern plate hole punched device and the hole-punching method that adopt the utility model embodiment to provide, can reach following technique effect:
Owing to adopting aluminum alloy pattern plate hole punched device and hole-punching method that workpiece 16 is carried out charging, punching, unclamped and the operation of discharging, without manual operation, increase safety coefficient, machining accuracy is high, and production efficiency is high.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
