Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, positioning precision is high, production efficiency is high punching die.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of punching die, comprise upper die and lower die, described patrix comprises upper bolster, fixed head and upper male mould, described upper male mould is fixed on upper bolster, described fixed head is connected by spring stack with upper bolster, described upper male mould runs through fixed head, described counterdie comprises die shoe, lower cavity die and stock guide, described lower cavity die and stock guide are arranged on die shoe, described patrix also comprises fine positioning pin and pilot pin, described fine positioning pin and pilot pin all run through fixed head, and be fixed on upper bolster, described pilot pin profile is consistent with processed pass, described stock guide bilateral symmetry arranges two pin-and-hole seats, described fine positioning pin-and-hole is corresponding up and down with fine positioning pin, and dead in line.
Preferably, described fine positioning pin is 4, and the corresponding fine positioning pin-and-hole arranging is located at stock guide both sides and in lower cavity die one side.
Preferably, described fixed head is split type, and inner interlayer is provided with air cavity, described air cavity external gas source.
The beneficial effect that adopts technique scheme to produce is: when sheet material carries out punching processing on automatic punch production line, when slider of punch is displaced downwardly to bottom, fixed head plays guiding corrective action to upper male mould, stock guide is treated machining sheet and is play the guiding role, fine positioning pin plays auxiliary positioning effect to upper male mould simultaneously, when sheet material carries out continuous punching processing, finished sheet material reach, when next stroke punching, the pilot pin of patrix coincide with finished pass, punching is played to secondary positioning action, guarantee punching processing precision, be arranged on air cavity in fixed head when upper male mould punching processing simultaneously, can blow off adding the waste material bits that produce man-hour, prevent from piling up and block, scratch finished surface, affect sheet material crudy, can reduce labor intensity of operating staff.The utlity model has advantage simple in structure, that positioning precision is high, production efficiency is high, guarantee product quality, reduce labour intensity, be convenient to maintaining.
Accompanying drawing explanation
Fig. 1 is the upper die structure schematic diagram of an embodiment of the utility model;
Fig. 2 is the top view of the corresponding counterdie of patrix in Fig. 1;
In figure: 1-upper bolster, 2-fixed head, 3-upper male mould, 4-spring stack, 5-die shoe, 6-lower cavity die, 7-stock guide, 8-fine positioning pin, 9-pilot pin, 10-fine positioning pin-and-hole, 11-air cavity.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, a kind of punching die shown in 2, comprise upper die and lower die, described patrix comprises upper bolster 1, fixed head 2 and upper male mould 3, described upper male mould 3 is fixed on upper bolster 1, described fixed head 2 is connected by spring stack 4 with upper bolster 1, described upper male mould 3 runs through fixed head 2, described counterdie comprises die shoe 5, lower cavity die 6 and stock guide 7, described lower cavity die 6 and stock guide 7 are arranged on die shoe 5, described patrix also comprises fine positioning pin 8 and pilot pin 9, described fine positioning pin 8 and pilot pin 9 all run through fixed head 2, and be fixed on upper bolster 1, described fine positioning pin 8 is 4, described stock guide 7 bilateral symmetry arrange two pin-and-hole seats, described fine positioning pin-and-hole 10 is corresponding Shang Xia 8 with fine positioning pin, and dead in line, described pilot pin 9 profiles are consistent with processed pass, corresponding fine positioning pin-and-hole 10 is set on described stock guide 7, described pilot pin 9 is corresponding with finished hole.When patrix is displaced downwardly to punching processing position, fixed head 2 can move along spring stack 4, make upper male mould 3 under the guiding corrective action of fixed head 2, accurately be positioned at punching position, the fine positioning pin 8 that is simultaneously symmetricly set on stock guide 7 both sides inserts fine positioning pin-and-hole 10, described fine positioning pin 8 is little matched in clearance with fine positioning pin-and-hole 10, improved the positioning precision of upper male mould 3, and after the reach of position, finished hole, treat that next machining position adds man-hour, the pilot pin 9 being arranged on patrix inserts in finished hole, carry out position, hole centering, punching precision is carried out to secondary location, improved punching processing precision, guaranteed product quality.In addition, in the utility model, the shape of upper male mould 3 and quantity can not stick to a kind of form, can specifically determine according to need of production.
