Abstract

The invention discloses a U-shaped support punching blanking bending composite die. Blanking, bending and punching of a U-shaped support are completed through one die, production efficiency is high, used process devices are few, economic benefit is high, and the problem that an existing U-shaped support needs a blanking die, a bending die and a punching die and low production efficiency, large process device number and low economic benefit are caused is solved.

Description

A kind of U-shaped support punching and blanking bends composite die
Technical field
The present invention relates to field of machining, particularly relate to a kind of U-shaped support punching and blanking and bend composite die.
Background technology
General U-shaped trestle component is all will to bend after first punching and blanking or after first bending, punching and blanking just can complete, such technique needs many equipment with artificial, the consumption energy is large, and various due to operation, every procedure has certain error, so cause the accumulated error of product larger, if and the bending again of first punching and blanking, increase human resources, increase the production time, reduce operating efficiency.
Summary of the invention
The present invention its object is to provide a kind of U-shaped support punching and blanking to bend composite die, realize disposable complete U-shaped support punching, blanking and bending, thus ensure processing quality and enhance productivity.
For realizing the object of the invention, the technical scheme of employing is:
A kind of U-shaped support punching and blanking bends composite die, comprise upper bolster and die shoe, it is characterized in that, upper bolster lower end is provided with installing plate, die is provided with between installing plate and die shoe, bottom and the die shoe of die are fixed, the top of die is provided with plate, plate one end is provided with alignment pin, alignment pin is connected with die, wedge is fixed between installing plate and die shoe, the fixing top of wedge contacts with the bottom of installing plate, fixing wedge is arranged in the end face scope of die, the formation inclined-plane, bottom of fixing wedge, fixing wedge side is connected with installing plate and upper bolster by pull bar, pull bar lower end is provided with compact heap, fix and be provided with spring between wedge and compact heap, spring fitting is on pull bar.Forming terrace die is provided with in the middle of die shoe, forming terrace die top is provided with holding pad, holding pad is provided with pull bar, the top of pull bar is arranged in upper bolster through installing plate, and the outer wall of pull bar is sheathed with spring, and the two ends of spring contact with installing plate with holding pad respectively, die shank is provided with in upper bolster, the bottom of die shank is arranged in the cavity of fixing wedge through upper bolster, and the bottom of die shank is fixed with piercing punch, and piercing punch is arranged in forming terrace die through after cavity and holding pad.
Further, the bottom of described upper bolster is provided with upper guide bush, and the top of die shoe is provided with lower guide pin bushing, is provided with guide pillar between upper guide bush and lower guide pin bushing, the two ends of guide pillar are separately positioned in upper guide bush and lower guide pin bushing, and the dead in line of the axis of the axis of guide pillar, upper guide bush, lower guide pin bushing.
Beneficial effect of the present invention: this mould adopts one set of die to complete the blanking of U-shaped support, bending and punching, production efficiency is high, operation equipment is few, high financial profit, solve existing U-shaped rack forming and adopt blanking, bending and punching 3 mold, the production efficiency caused is low, technological equipment is many, the problem of deficiency in economic performance.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of U-shaped support punching and blanking bends composite die.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
A kind of U-shaped support punching and blanking bends composite die as shown in Figure 1, comprising: upper bolster 5, fixing wedge 11; Spring 12, die shank 8, pull bar 6, installing plate 10, plate, guide pillar 3, die 15, lower guide pin bushing 2, die shoe 1, spring 9, pull bar 7, forming terrace die 19, holding pad 17, alignment pin 14, piercing punch 18, upper guide bush 4, compact heap 13 and workpiece 16.Upper bolster 5 lower end is provided with installing plate 10, die 15 is provided with between installing plate 10 and die shoe 1, bottom and the die shoe 1 of die 15 are fixed, the top of die 15 is provided with plate, plate one end is provided with alignment pin 14, alignment pin 14 is connected with die 15, wedge 11 is fixed between installing plate 10 and die shoe 1, the top of fixing wedge 11 contacts with the bottom of installing plate 10, fixing wedge 11 is arranged in the end face scope of die 15, the formation inclined-plane, bottom of fixing wedge 11, fixing wedge 11 side is connected with installing plate 10 and upper bolster 11 by pull bar 6, pull bar 6 lower end is provided with compact heap 13, fix and be provided with spring 12 between wedge 11 and compact heap 13, spring 12 is arranged on pull bar 6.Forming terrace die 19 is provided with in the middle of die shoe 1, forming terrace die 19 top is provided with holding pad 17, holding pad 17 is provided with pull bar 7, the top of pull bar 7 is arranged in upper bolster 5 through installing plate 10, the outer wall of pull bar 7 is sheathed with spring 9, the two ends of spring 9 contact with installing plate 10 with holding pad 17 respectively, die shank 8 is provided with in upper bolster 5, the bottom of die shank 8 is arranged in the cavity of fixing wedge 11 through upper bolster 5, the bottom of die shank 8 is fixed with piercing punch 18, and piercing punch 18 is arranged in forming terrace die 19 through after cavity and holding pad 17.
