Abstract
The utility model discloses a convex hull forming die. The die comprises an upper die (1) and a lower die (2) which are arranged correspondingly, wherein the upper die (1) sequentially comprises an upper die frame plate (10), an upper die base plate (12), an upper die fixing plate (14) and a stripper plate (16); the lower die (2) sequentially comprises a lower plate (18), a lower die base plate (20) and a lower die frame plate (22); and a convex die (24) is arranged on the stripper plate (16), and a concave die (26) corresponding to the convex die (24) is formed on the lower plate (18). The die is characterized in that a sliding block (28) is arranged in the stripper plate (16), the convex die (24) penetrates through the sliding block (28), and the top end of the sliding block (28) is contacted with the stripper plate (16) through an elastic element (30). According to the convex hull forming die, the defective rate is low, and the product quality is stable.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of convex hull forming die.
Background technology
Development along with industry, the use of stamping parts product is more and more, therefore the quality of stamping parts product is also had higher requirement, the stamping parts product is mainly by the die cutting die punch forming, so the stability of die cutting die has vital effect to the quality of stamping parts product.
At present, employed convex hull forming die when punching press has the stamping parts product of convex closure is because it directly adopts punch at sheet material upper punch belling bag, although this kind mode is simple, but can the sheet material of convex closure periphery be damaged, therefore exist defect rate high, the defective of unstable product quality and problem.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of defect rate is low, the convex hull forming die of constant product quality.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of convex hull forming die, comprise the corresponding upper die and lower die that arrange, described patrix comprises the patrix frame plate successively, upper die plate, upper mould fixed plate and stripper, described counterdie comprises lower bolster successively, counterdie backing plate and counterdie frame plate, be provided with punch on the described stripper, be provided with the die corresponding with described punch on the described lower bolster, be provided with a slide block in the described stripper, described punch passes from described slide block, and the top of described slide block contacts with described stripper by flexible member.
Described flexible member is helical spring.
Described flexible member is the rubber ring that is sleeved on the described punch.
Be provided with the stripper backing plate between described upper mould fixed plate and the described stripper.
Compared with prior art, the beneficial effects of the utility model are:
Because a kind of convex hull forming die of the present utility model is provided with slide block in stripper, when the downward pressing sheet material of patrix, slide block at first contacts sheet material and is pressed on the sheet material, thereby play the effect of stablizing sheet material, to such an extent as to punch sheet material when pressing sheet material can not move, thereby can effectively improve yield rate, so the utility model defect rate is lower, product quality is more stable.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Among the figure: patrix 1, counterdie 2, patrix frame plate 10, upper die plate 12, upper mould fixed plate 14, stripper backing plate 15, stripper 16, lower bolster 18, counterdie backing plate 20, counterdie frame plate 22, punch 24, die 26, slide block 28, flexible member 30.
The specific embodiment
Referring to shown in Figure 1, a kind of convex hull forming die of the present utility model, comprise corresponding patrix 1 and the counterdie 2 that arranges, wherein patrix 1 comprises patrix frame plate 10 successively, upper die plate 12, upper mould fixed plate 14, stripper backing plate 15 and stripper 16, comprise successively lower bolster 18 at counterdie 2, counterdie backing plate 20 and counterdie frame plate 22, be provided with punch 24 on the stripper 16, be provided with the die 26 corresponding with described punch 24 on the lower bolster 18, special feature of the present utility model is: be provided with a slide block 28 in stripper 16, punch 24 passes from slide block 28, and the top of slide block 28 contacts with stripper 16 by flexible member 30.During actual the use, slide block 28 is at first stablized the effect that sheet material prevents that sheet material from moving by being pressed on the sheet material, playing, thereby effectively improves yield rate.
When making convex hull forming die of the present utility model, flexible member 30 can be selected helical spring or rubber ring.
In sum, the utility model defect rate is lower, and product quality is more stable.
The above only is preferred embodiments of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
