Abstract
The utility model discloses a bending compound die which comprises an upper die base, a left male die, a right male die, a stripper plate, a female die and an ejection block, wherein the left male die and the right male die are symmetrically fixedly arranged on the upper die base, the stripper plate is located between the left male die and the right die base and movably arranged on the upper die base, and a first elastic body is arranged between the stripper plate and the upper die base. The female die is provided with a narrow mouth hole cavity, a blind hole is formed in the bottom of the narrow mouth hole cavity, the ejection block is movably arranged in the blind hole, and a second elastic body is arranged between the ejection block and the bottom of the blind hole. The die can achieve one-shot forming of turnup U-shaped bending, is simple in structure, low in manufacturing cost, convenient to maintain, and long in service life, and can reduce production cost.
Description
Technical field
The utility model relates to the cold punching technology processing technique field, is specifically related to a kind of crooked compound die.
Background technology
The U-shaped bending structure of flange generally needs the twice molding procedure: promptly the first road U-shaped is shaped the second road 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 compound die 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 purpose of this utility model is to provide a kind of crooked compound die, can realize the once-forming of flange U-shaped bending, and simple in structure, and cost of manufacture is lower, is convenient to safeguard, therefore long service life can reduce production costs.
To achieve these goals, the technical scheme that the utility model proposes 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 utility model, described elastomer one is a spring, and described elastomer two is a spring.
As the further improved crooked compound die of the utility model, 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, 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 utility model 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

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 to understanding of the present utility model, the utility model is done describing in further detail below in conjunction with drawings and Examples, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Shown in Fig. 1-3, the crooked compound die that present embodiment provided, 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 a spring, and described elastomer 28 is a 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 are used for fixing machining sheet 11, described left punch 2, right punch 3, holding pad 4 and ejection block 6 are descending jointly, 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, promptly finish flange U-shaped bending operation.
The crooked compound die that present embodiment provided 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.
