Abstract
The invention discloses a bent compound die which comprises an upper die holder, a left convex die, a right convex die, a pressure plate, a concave die and an ejection block, wherein the left convex die and the right convex die are symmetrically and fixedly arranged on the upper die holder, the pressure plate is arranged between the left convex die and the right convex die and movably arranged on the upper die holder, and an elastomer 1 is arranged between the pressure plate and the upper die holder; and the concave die is provided with a narrow-mouth cavity, the bottom of the narrow-mouth cavity is provided with a blind hole, the ejection block is movably arranged in the blind hole, and an elastomer 2 is arranged between the ejection block and the bottom of the blind hole. The die disclosed by the invention can realize the one-time forming of flanging U-shaped bending, and is simple in structure, low in production costs, easy to maintain and long in service life, therefore, the die can reduce the production cost.
Description
Technical field
The present invention relates to the cold punching technology processing technique field, be specifically related to a kind of crooked compound die.
Background technology
The U-shaped bending structure of flange generally needs the twice molding procedure: namely the first U-shaped is shaped, the second flanging forming.The U-shaped bending compound die of the flange of a lot of once-formings is also disclosed in the prior art, but these composite mould structures are comparatively complicated, cost of manufacture is higher, and be not easy to safeguard, service life is short, therefore production cost is higher, needs further to improve, and realizes the once-forming of flange U-shaped bending so that the simpler mould of structure to be provided.
Summary of the invention
The object of the present invention is to provide a kind of crooked compound die, can realize the once-forming of flange U-shaped bending, and simple in structure, cost of manufacture is lower, is convenient to safeguard, and therefore long service life can reduce production costs.
To achieve these goals, the technical scheme of the present invention's proposition is:
A kind of crooked compound die, comprise upper bolster, left punch, right punch, holding pad, die, ejection block, described left punch, right punch are fixedly arranged on described upper bolster symmetrically, described holding pad is between described left punch, right punch and be movably set in described upper bolster, is provided with elastomer one between described holding pad and the described upper bolster; Described die is provided with the slot vestibule, and described slot vestibule bottom is provided with blind hole, and described ejection block is movably set in the described blind hole, is provided with elastomer two between described ejection block and the described blind hole bottom.
As the further improved crooked compound die of the present invention, crooked compound die, described elastomer one is spring or rubber spring, described elastomer two is spring or rubber spring.
As the further improved crooked compound die of the present invention, crooked compound die, also comprise movable post, described holding pad is fixedly arranged on described movable column bottom, described upper bolster middle part is provided with through hole, described through hole is passed in described movable post upper end, and described movable post upper end is provided with limited cap, described elastomer one coaxial being arranged on the described movable post.
Crooked compound die provided by the present invention can be realized the once-forming that the flange U-shaped bends, and simple in structure, and cost of manufacture is lower, is convenient to safeguard that therefore long service life has reduced production cost.
Description of drawings
Fig. 1, status architecture schematic diagram before the crooked compound die bending;
Fig. 2, crooked compound die flange bending state structural representation;
Fig. 3, crooked compound die U-shaped bending state structural representation.
1 is upper bolster, and 2 is left punch, and 3 is right punch, and 4 is holding pad, and 5 is die, and 6 is ejection block, and 7 is that elastomer one, 8 is that elastomer two, 9 is movable post, and 10 is limited cap, and 11 is machining sheet.
The specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples the present invention is done to describe in further detail, this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.
Shown in Fig. 1-3, the crooked compound die that present embodiment provides, comprise upper bolster 1, left punch 2, right punch 3, holding pad 4, die 5, ejection block 6, described left punch 2, right punch 3 are fixedly arranged on described upper bolster 1 symmetrically, described holding pad 4 is between described left punch 2, right punch 3 and be movably set in described upper bolster 1, is provided with elastomer 1 between described holding pad 4 and the described upper bolster 1; Described die 5 is provided with the slot vestibule, and described slot vestibule bottom is provided with blind hole, and described ejection block 6 is movably set in the described blind hole, is provided with elastomer 28 between described ejection block 6 and the described blind hole bottom.Described elastomer 1 is spring or rubber spring, and described elastomer 28 is spring or rubber spring.
Further improve as present embodiment, also comprise movable post 9, described holding pad 4 is fixedly arranged on described movable post 9 bottoms, described upper bolster 1 middle part is provided with through hole, described through hole is passed in described movable post 9 upper ends, described movable post 9 upper ends are provided with limited cap 10, described elastomer one 7 coaxial being arranged on the described movable post 9.
During work, described upper bolster 1, left punch 2, right punch 3, holding pad 4 are descending together, described holding pad 4 and ejection block 6 effects are used for fixedly machining sheet 11, described left punch 2, right punch 3, holding pad 4 and ejection block 6 are jointly descending, and the slot of described die 5 is realized flange with machining sheet 11; After described left punch 2, right punch 3, holding pad 4, machining sheet 11 pass die 5 slots, described ejection block 6 and holding pad 4 stop descending, described left punch 2, right punch 3 continue descending, and machining sheet 11 is realized the U-shaped bending, namely finish flange U-shaped bending operation.
The crooked compound die that present embodiment provides can be realized the once-forming that the flange U-shaped bends, and simple in structure, and cost of manufacture is lower, is convenient to safeguard that therefore long service life has reduced production cost.
