Description

It is a kind of to forge the special cold punching composite die of disk

Technical field

The utility model is related to ferrous metal pressure processing technical field of mold, more particularly to a kind of forging disk is special Cold punching composite die.

Background technology

Disk forging products are forged, product is typical stephanoporate thin wall part, there is 4 big scallop hole and 4 small diamond holes.Before Phase manufactures experimently the forging, tries out 8 holes of compound die one-step punching, and endoporus drift is excessively intensive, and during punching, forging material is mutually extruded Seriously, cause plucking thorn long, greatly, mould is fragile for mold friction.If whole cold punchings, aperture drift abrasion is also very big.

The content of the invention

The utility model provides a kind of special cold punching composite die of forging disk, compensate for single multiple using heat punching The deficiency of matched moulds or cold punching compound die；Using guide pillar, guide sleeve structure, the unbalance loading of blanking pressure is reduced, mould is improved in punching The stability of process；So as to ensure that product quality.

In order to solve the above technical problems, the utility model provides a kind of special cold punching composite die of forging disk, Including upper die and lower die, upper mould includes die shank, upper baffle plate, drift, interior hexagonal and hangs bolt, polyurethane glue stick, guide sleeve, socket cap Hexagon socket head cap screw, stripper, described die shank are enclosed on baffle plate and are fixed on press ram pedestal endoporus, and die shank leads to Thread spindle fastening drift is crossed, guide sleeve is fixed on upper baffle plate with socket cap hexagon socket head cap screw, and drift lower end is enclosed on stripper In, stripper and polyurethane glue stick is cased with, is relatively fixed by the connection of socket cap hexagon socket head cap screw on upper baffle plate；

Lower mould includes lead, punching bed die, bed die backing plate, guide pillar seat, socket cap hexagon socket head cap screw, bottom plate, lead It is fixed on guide pillar seat, socket cap hexagon socket head cap screw on bottom plate, lead is slidably matched with guide sleeve, punching bed die is with socket cap Hexagon socket head cap screw is fixed on bed die backing plate, and bed die backing plate is fixed on bottom plate with socket cap hexagon socket head cap screw.

As a preferred technical scheme of the present utility model, described drift is made by Cr12MoV materials, heat treatment Hardness HRC58-63.

As a preferred technical scheme of the present utility model, the gap that described lead is slidably matched with guide sleeve For 0.15~0.2mm.

As a preferred technical scheme of the present utility model, described punching bed die is made by Cr12MoV materials, with The unilateral gap of drift is -0.3~-0.4m, heat treatment hardness HRC58-63.

The one or more technical schemes provided in the embodiment of the present application, have at least the following technical effects or advantages：

It compensate for the single deficiency that compound die or cold punching compound die are rushed using heat；Using guide pillar, guide sleeve structure, punching is reduced The unbalance loading of power is cut out, stability of the mould in blanking process is improved；So as to ensure that product quality.

Brief description of the drawings

, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only Some embodiments of the present utility model, for those of ordinary skill in the art, are not paying the premise of creative labor Under, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is overall structure diagram of the present utility model.

Embodiment

In order to be better understood from above-mentioned technical proposal, below in conjunction with Figure of description and specific embodiment to upper Technical scheme is stated to be described in detail.

As shown in figure 1, a kind of special cold punching composite die of forging disk described in the present embodiment, by upper and lower module Into accurately guiding punching station surely by guide frame.

Upper mould includes die shank 1, upper baffle plate 2, drift 3, interior hexagonal and hangs bolt 4, polyurethane glue stick 5, guide sleeve 6, socket cap Hexagon socket head cap screw 7, stripper 8.Wherein, die shank 1 is enclosed on baffle plate 2 and is fixed on press ram pedestal endoporus；Mould Handle 1 fastens drift 3 by thread spindle；Guide sleeve 6 is fixed on upper baffle plate 2 with socket cap hexagon socket head cap screw 7；The lower end of drift 3 It is enclosed in stripper 8；Stripper 8 and polyurethane glue stick 5 is cased with, is relatively fixed by the connection of socket cap hexagon socket head cap screw 7 upper On baffle plate 2；Wherein, drift 3 is made by Cr12MoV materials, is designed according to forging's block dimension, heat treatment hardness HRC58-63.

Lower mould includes lead 9, punching bed die 10, bed die backing plate 11, socket cap hexagon socket head cap screw 12, guide pillar seat 13, circle Column cap hexagon socket head cap screw 14, bottom plate 15, socket cap hexagon socket head cap screw 16.Wherein, lead 9 is with guide pillar seat 13, socket cap six Corner bolt 14 is fixed on bottom plate 15, and lead 9 is slidably matched with guide sleeve 6,0.15~0.2mm of gap；Punching bed die 10 with Socket cap hexagon socket head cap screw 16 is fixed on bed die backing plate 11, is made by Cr12MoV materials, with the unilateral gap of drift 3 for- 0.3~-0.4m, heat treatment hardness HRC58-63；Bed die backing plate 11 is fixed on bottom plate 15 with socket cap hexagon socket head cap screw 12.

During work, when slider of punch runs supreme flex point, forging disk is placed on bottom punch bottom hole mould 10, press pressure machine sliding Block is descending, and stripper 8 is contacted with circle square plate bottom forging, and the promotion of stripper 8 polyurethane glue stick 5 is up, and polyurethane glue stick 5 is by upper mould The limitation of bottom plate 2, applying reaction force makes stripper 8 gradually compress forging disk, and drift 3 also approaches forging disk endoporus；Punching First 3 continue traveling downwardly, and the overlap punching forged in disc hole are removed, overlap is successively from punching bed die 10, bed die backing plate 11, bottom plate 15 Drop；When slider of punch is run to lower flex point, slider of punch start it is up, drift 3 from punching bed die 10 and forging disk endoporus Middle to retract, the gradually load removal of polyurethane glue stick 5, stripper 8 departs from forging disk, up with press ram, completes once Compound punching process.

Wherein, it is pre- before polyurethane glue stick 5,8 pairs of forging disk punchings of stripper due to guide pillar guide sleeve structure in punching Compress, it is therefore prevented that punching distortion, it is ensured that forging quality.

It is described above, only it is preferred embodiment of the present utility model, not makees any formal to the utility model Limitation, although the utility model is disclosed above with preferred embodiment, but is not limited to the utility model, any ripe Professional and technical personnel is known, is not being departed from the range of technical solutions of the utility model, when in the technology using the disclosure above Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as without departing from technical solutions of the utility model Hold, any simple modification, equivalent variations and the modification made according to technical spirit of the present utility model to above example, still Belong in the range of technical solutions of the utility model.
