Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of mould for punching press.
Background technology
Mould is in manufacture processing use procedure, the impact wearability problem produced when mould uses can be related to, mould especially in punching press use procedure unbalance stress can cause rigid impact and loss to some areas, service time is too much, directly affect punching press product quality out, affect the follow-up of product use and assemble, one set of die causes needing again to manufacture, change because of local cause, affects production efficiency.
Utility model content
In order to overcome a difficult problem for above-mentioned prior art, it is simple, easy to use that the utility model provides a kind of structure, can improve a kind of diel of mould service efficiency.
In order to achieve the above object, the utility model is realized by following scheme, a kind of diel, comprise: upper bolster, middle die holder, hollow part, bolt hole, stud, die shoe, punch, milling dead zone, counterbore, alloy portion, it is characterized in that: the lower end of described upper bolster is provided with middle die holder, described middle die holder centre position is provided with hollow part, surrounding is provided with four bolts hole, described middle die holder lower end is provided with die shoe, described die shoe surrounding is provided with four studs, punch is provided with in the middle of described die shoe, milling dead zone is provided with in the middle of described punch, described punch is provided with alloy portion, described alloy portion is provided with counterbore, described alloy portion is fixed on punch by bolt through counterbore, the outline of described hollow part matches with punch outline, four described bolts hole are corresponding with four stud positions, in the middle of described milling dead zone, vacant position adopts layering milling empty, described alloy portion adopts alloy material, the top edge of described counterbore is inwardly in circular arc chamfering.
The utility model can be found out in sum, general diel is all made up of two parts, a middle die holder is added in this structure, middle die holder is enclosed within the punch of die shoe, make stamping parts table top in installation course steady, stamping parts is not easily made to occur placing injustice owing to being placed on separately on punch, affect punching press effect, conveniently and firmly middle die holder is placed on the punch of die shoe, die shoe arranges four studs, middle die holder arranges four bolts hole, after stud is corresponding with bolt hole, then bolt is used to fix, distortion can not be caused because of position instability extruding punch in milling dead zone like this in the middle of die holder, affect stamping products quality, in order to prevent local punching press stressed excessive, use alloy portion assembled at stressed excessive position, alloy portion adopts alloy material, there is the characteristic of wear and shock-resistant, not fragile and distortion, impaired in order to prevent distortion, alloy portion is provided with multiple counterbore, the effect of counterbore uses hexagon socket head cap screw to be fixed on punch by alloy portion, and interior hexagonal itself is inserted in counterbore, mold use quality can not be affected, stamping parts is impacted in punching course to prevent counterbore position, counterbore edge uses inwardly in circular arc chamfering shape, can find out in sum, the position damaged adopts the alloy portion of alloy material to carry out assembled, even if occur damaging, use bolt is fixed, it is convenient to change, mold use efficiency is improved.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein: 1, upper bolster; 2, middle die holder; 3, hollow part; 4, bolt hole; 5, stud; 6, die shoe; 7, punch; 8, milling dead zone; 9, counterbore; 10, alloy portion.
Detailed description of the invention
As shown in Figure 1, a kind of diel, comprise: upper bolster 1, middle die holder 2, hollow part 3, bolt hole 4, stud 5, die shoe 6, punch 7, milling dead zone 8, counterbore 9, alloy portion 10, it is characterized in that: the lower end of described upper bolster 1 is provided with middle die holder 2, described middle die holder 2 centre position is provided with hollow part 3, surrounding is provided with four bolts hole 4, described middle die holder 2 lower end is provided with die shoe 6, described die shoe 6 surrounding is provided with four studs 5, punch 7 is provided with in the middle of described die shoe 6, milling dead zone 8 is provided with in the middle of described punch 7, described punch 7 is provided with alloy portion 10, described alloy portion 10 is provided with counterbore 9, described alloy portion 10 is fixed on punch 7 by bolt through counterbore 9, the outline of described hollow part 3 matches with punch 7 outline, four described bolts hole 4 are corresponding with four stud 5 positions, in the middle of described milling dead zone 8, vacant position adopts layering milling empty, described alloy portion 10 adopts alloy material, the top edge of described counterbore 9 is inwardly in circular arc chamfering.
The utility model implements like this, as shown in Figure 1, carry out following operation successively: between upper bolster 1 and die shoe 6, be provided with die holder 2 in, in the centre position of middle die holder 2, a hollow part 3 is set, hollow part 3 is consistent with punch 7 outline on die shoe 6, the height of punch 7 is consistent with the degree of depth of hollow part, in the surrounding of middle die holder 2, four bolts hole 4 are set, in the surrounding of die shoe 6, four studs 5 are set, the punch 7 of die shoe 6 is provided with milling dead zone 8, this milling dead zone 8 carries out setting according to the shape needed that manufactures a product, the inside adopts layering to carry out milling sky, adopt alloy portion 10 assembled in the punch 7 the strongest place of extruding that is hit, alloy portion 10 is provided with counterbore 9, hexagon socket head cap screw is used to submerge counterbore, alloy portion 10 is fixed on punch 7, this structure uses like this, by the hollow part 3 on middle die holder 2, bolt hole 4 corresponds to the punch 7 of die shoe 6 respectively, on stud 5, use bolted stud 5, like this, die holder 2 and die shoe 6 are in an entirety, above stamping parts blank is placed into, upper bolster is punched down, complete operation, as occurred, stressed large alloy portion 10 damages, timely replacing alloy portion 10, without the need to more mold exchange.
Can be found out by above embodiment, the utility model has the advantages that structure is simple, easy to use, improve mould utilization factor and production efficiency.
