Abstract
The utility model relates to cold-punching die discharge technique, in particular to a cold-punching die discharge device without a fixed plate. The cold-punching die discharge device without the fixed plate comprises an upper die base and a lower die base which are arranged on a punching machine. A concave die and a material punching block are arranged on the lower surface of the upper die base, the material punching block is arranged in the middle of the concave die, and the upper portion of the material punching block is connected with a material punching rod penetrating through the upper die base. The cold-punching die discharge device without the fixed plate is characterized in that the upper portion of the lower die base is provided with guide location pin fixing plates through location pins, a convex die is fixed at the upper portions of the guide location pin fixing plates through guide location pins, the convex die penetrates through the guide location pin fixing plates to be fixed on the lower die base through fastening screws, rectangular springs are arranged in the guide location pin fixing plates on two sides of the convex die, the top ends of the rectangular springs are connected with discharge plates, and discharge screws penetrate through the rectangular springs to be fixed on the lower die base. Thus, the cold-punching die discharge device is reasonable in design, practical and convenient.
Description
(1) technical field
The utility model relates to cold-punching mould blanking technology, and is particularly a kind of without the fixed head cold punching die doffer.
(2) background technology
The blanking die punch is fixed the mode that mostly adopts the fixed head solid punch in the same industry at present, the fixed head of this mode is thicker, after the punch wearing and tearing, need carry out grinding, the contained punch of fixed head can not be counted effective depth, the mold materials utilization rate is low, can only become waste material behind the sharpening several times, larger increase cost.
(3) summary of the invention
The utility model provides a kind of reasonable in design in order to remedy the deficiencies in the prior art, and structure is easily without the fixed head cold punching die doffer.
The utility model is achieved by the following technical solution:
A kind of without the fixed head cold punching die doffer, comprise the upper bolster and the die shoe that are installed on punch press, the upper bolster lower surface is equipped with die and dnockout piece by screw, the dnockout piece is positioned at the die middle part, dnockout piece top is connected with the knockout rod that passes upper bolster, it is characterized in that: described die shoe top is provided with correcting alignment pin fixed head by alignment pin, correcting alignment pin fixed head top is fixed with punch by the correcting alignment pin, and punch passes correcting alignment pin fixed head by trip bolt and is fixed on the die shoe; Nest has Rectangular Spring in the correcting alignment pin fixed head of described punch both sides, and the Rectangular Spring top is connected with stripper plate, is installed with in the Rectangular Spring to be fixed in to take off the material screw on the die shoe.
Be folded with correcting alignment pin backing plate between described correcting alignment pin fixed head and the die shoe.
The beneficial effects of the utility model are: this utility model simple in structure without the fixed head cold punching die doffer, reasonable in design, and novelty is skillfully constructed, die life is high, easy to maintenance, improve the mould punch life-span and reduced die cost, be suitable for wide popularization and application.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
Among the figure, 1 stripper plate, 2 Rectangular Springs, 3 take off the material screw, 4 correcting alignment pin fixed heads, 5 correcting alignment pin backing plates, 6 correcting alignment pins, 7 punch, 8 trip bolts, 9 alignment pins, 10 die shoes, 11 steel plates, 12 dies, 13 dnockout pieces, 14 knockout rods.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises upper bolster and the die shoe 6 that is installed on punch press, the upper bolster lower surface is equipped with die 12 and dnockout piece 13 by screw, dnockout piece 13 is positioned at die 12 middle parts, dnockout piece 13 tops are connected with the knockout rod 14 that passes upper bolster, it is characterized in that: described die shoe 10 tops are provided with correcting alignment pin fixed head 4 by alignment pin 9, correcting alignment pin fixed head 4 tops are fixed with punch 7 by correcting alignment pin 6, and punch 7 passes correcting alignment pin fixed head 4 by trip bolt 8 and is fixed on the die shoe 10; The correcting alignment pin fixed head 4 interior nests of described punch 7 both sides have Rectangular Spring 2, and Rectangular Spring 2 tops are connected with stripper plate 1, be installed with in the Rectangular Spring 2 be fixed on the die shoe 10 taking off the material screw 3; Be folded with correcting alignment pin backing plate 5 between described correcting alignment pin fixed head 4 and the die shoe 10.
Adopt of the present utility model without the fixed head cold punching die doffer, in the time of stamping-out, steel plate 11 is positioned on the punch 7 by correcting alignment pin 6, slider of punch drive patrix is descending, and die 12 is pressed on the steel plate 11, then unconventional flitch 1 compression Rectangular Spring 2, punch 7 gos deep into steel plate 11 gradually, when slide block reached bottom dead centre, punch 7 just pushed the steel backing that is shaped in the die 12, finishes stamping-out.Then slide block is up, when again reaching top dead-centre, promotes dnockout piece 13 by knockout rod 14, and steel backing is released from die 12.
Claims (2)
