Specific embodiment

The utility model provides a kind of continuous stamping die of pedal assembly L-type support.It is practical to this below in conjunction with attached drawing New technique scheme is described in detail, so that it is more readily understood and grasps.

A kind of continuous stamping die of pedal assembly L-type support, as shown in figure 3, L-type support 1 includes bracket in curved surface Main body 11, the intrados 12 of rack body 11 are equipped with the indent support portion 13 for abutting against with tubular structural member, indent branch 13 side of support part is equipped with the positioning indent 14 for having angle-style, positions and is equipped with lock-bit through-hole 15 in indent 14, and the one of rack body 11 End is equipped with the alar part 16 to turn up towards the extrados of rack body 11.This L-type support 1 belongs to the prior art, and details are not described herein Its purposes and related description.

As depicted in figs. 1 and 2, continuous stamping die includes continuous punching upper mold 2 and continuous punching lower die 3.

Wherein, as shown in Figure 1, continuous punching upper mold 2, which is equipped with location hole along material strip step direction, is punched block 21, the first trimming Be punched block 22, the second trimming punching block 23, third trimming punching block 24, the 4th trimming punching block 25, thick embryo forming pressing block 26, Rack forming pressing block 27, lock-bit through-hole punching block 28, discharging are punched block 29.

As shown in Fig. 2, continuous punching lower die 3 is equipped with location hole evacuation mould 31, the first trimming evacuation along material strip step direction Mould 32, the second trimming evacuation mould 33, third trimming evacuation mould 34, the 4th trimming avoid mould 35, thick embryo forming mould 36, rack forming Mould 37, lock-bit through-hole evacuation mould 38, discharging avoid mould 39.

Under continuous punching upper mold 2 and 3 mated condition of continuous punching lower die, location hole is punched block 21 and location hole avoids mould 31 form location hole shaping stations, and the first trimming is punched block 22 and the first trimming evacuation mould 32, the second trimming are punched block 23 and the Two trimmings avoid mould 33, third trimming punching block 24 and third trimming evacuation mould 34, the 4th trimming punching block 25 and the 4th trimming Thick embryo outer rim shaping station is collectively formed in evacuation mould 35, and thick embryo forming pressing block 26 forms thick embryo forming work with thick embryo forming mould 36 Position, rack forming pressing block 27 and rack forming mould 37 form rack forming station, and lock-bit through-hole is punched block 28 and lock-bit through-hole It avoids mould 38 and forms lock-bit forming through holes station, discharging is punched block 29 and discharging evacuation mould 39 forms unloading station.

Forming principle of the material strip in continuous stamping die is illustrated in conjunction with Fig. 4:

Material strip enters in continuous stamping die, first passes around positioning hole forming, and location hole is used for the stepping position of material strip Control, it is ensured that the step-wise displacement of material strip is accurate, is punched block then in turn through the first, second, third and fourth trimming, realizes thick embryo outer rim Molding subsequently enters thick embryo forming station, realizes curved surface forming, alar part molding, positioning indent molding, it should be noted that with Upper three privileged sites molding can enter rack forming station with disposal molding or independent multistep molding after thick embryo forming, It needs to carry out the molding of bracket outer rim and the molding of indent support portion in rack forming station, lock-bit can be carried out after rack forming Through-hole machine-shaping separates the bracket of completion finally by unloading station.

Thick embryo forming station in this case is illustrated, thick embryo forming pressing block 26 includes curved surface forming portion 261, Curved surface forming portion 261 is equipped with positioning indent forming part 262 and alar part forming part 263, thick embryo forming mould 36 include with curved surface at The curved die 361 that type portion matches, curved die 361 be equipped with positioning indent forming part 262 match position interior cavity plate 362, And the alar part mould 363 to match with alar part forming part 263.

The citing scheme is integrated by curved surface forming, the molding of positioning indent and alar part molding, passes through a shaping station It can be realized, without multiple tracks shaping station, in addition, since curved surface, positioning indent, alar part belong to integral structure component, all It is vertically to deformation, therefore disposable punching press can ensure that its precision, prevent independent punching press from leading to the deformation for occurring interfering with each other.

Refinement explanation is carried out to the rack forming station in this case, rack forming pressing block 27 is formed including indent support portion Portion 271 and bracket outer rim forming part 272, rack forming mould 37 include the indent branch to match with indent support portion forming part 271 Support part mould 371 and the bracket outer rim shaping mould 372 to match with bracket outer rim forming part 272.

It specifically describes, material strip is impacted by the convex arc of indent support portion forming part 271 and forms indent support portion 13, bracket Outer rim forms the cooperation for needing bracket outer rim forming part 272 Yu bracket outer rim shaping mould 372, and bracket outer rim forming part 272 is recessed Channel-shaped, bracket outer rim shaping mould 372 is in punch-pin, and punch-pin two sides are equipped with groove, in bracket outer rim forming part 272 towards bracket Under 372 impact conditions of outer rim shaping mould, the exposed parts positioned at punch-pin two sides can form bracket outer rim to lower flange.

In order to increase the formed precision of bracket edge, continuous at least twice bracket can be set on even continuous stamping die Shaping station.It can ensure that the precision of bracket edge by multiple flange punching press.

By above description it can be found that a kind of continuous stamping die of pedal assembly L-type support of the utility model, design For the continuous stamping die of L-type support, by way of stepping L-type support can gradually be formed, formed precision it is high and High production efficiency.The continuous stamping die is able to achieve more highly difficult curved surface forming, the molding of indent support portion, alar part molding, determines Position indent molding and bracket edge molding, meet the processing demand of L-type support.Whole design is rigorous, it is succinct, reliable, Efficiently, production cost can be effectively reduced.

The technical solution of the utility model is fully described above, it should be noted that the tool of the utility model Body embodiment is simultaneously not limited by the description set out above, and those skilled in the art exist according to the Spirit Essence of the utility model All technical solutions that structure, method or function etc. are formed using equivalents or equivalent transformation, all fall within this reality Within novel protection scope.
