Abstract
The utility model relates to an anti-cracking blanking die for pressing V-shaped workpieces, which comprises an upper male die, a lower female die, an upper die holder and a lower die holder. Bolt mounting holes are arranged in the upper die holder and the lower die holder respectively, an upper pretightening bolt and a lower pretightening bolt are arranged in the bolt mounting holes respectively, and washers are arranged on the upper pretightening bolt and the lower pretightening bolt respectively. The anti-cracking blanking die has the advantages that 1 mounting and debugging of retaining walls when dies are mounted every time are omitted, the working strength of operators is relieved, and production efficiency is improved, 2 excessive loss and even damage caused by untight fit of the retaining walls and the die holders are avoided effectively, 3 the strength of the die is enhanced fundamentally, so that cracking of the die is prevented in advance, and 4 the anti-cracking blanking die is simple in structure and easy in manufacture, frequent detachment is omitted, and the strength of the die is ensured.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of concavo-convex mould of anti-cracking of suppressing the V-type product.
Background technology
Because diel V-type end face when punching press of compacting V-type product need bear the side force that stamping press decomposes horizontal direction; So usually because insufficient strength of mould own or operate miss are easy to cause cracking; Thereby make this mould material is just had very high requirement, and take certain measure to prevent the punch-die cracking.
Traditional method that prevents this type mould punch-die cracking is to add top retaining wall on mould V-type both sides, to bear the side force that stamping press resolves into, avoids because the excessive direct punch-die punching press fracture with mould of stamping press.
This method does not fundamentally strengthen the intensity of mould punch-die itself, just the side force barricade that passes to is to a certain extent born, and does not tackle the problem at its root.And barricade needs to cooperate closely with die holder, in case between leave the space, just possibly when punching press, cause damage, even scrap mould, cause tremendous loss.
The utility model content
The utility model is in order to overcome the above problems the concavo-convex mould of anti-cracking that the compacting V-type product that a kind of intensity is high, cracking resistance is good is provided.
The technical scheme of the utility model is: described concavo-convex mould comprises punch, lower cavity die, upper bolster, die shoe; Described going up in punch and the lower cavity die is respectively equipped with bolt mounting holes; Be respectively equipped with pretension bolt and following pretension bolt in the described bolt mounting holes, described going up on pretension bolt and the following pretension bolt is respectively equipped with packing ring.
The beneficial effect of the utility model is: all will carry out the installation and debugging of barricade when 1, having avoided each installation mold, alleviate operator's working strength, improve production efficiency; 2, the utility model has been avoided cooperating excessive loss even the damage that does not closely cause mould with die holder because of barricade effectively; 3, the utility model has fundamentally increased the intensity of mould itself, has prevented the cracking of mould in advance; 4, the utility model is simple in structure, and is easy to manufacture, need not frequent dismounting, and guaranteed the intensity of mould.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 is to go up punch, the 2nd, lower cavity die, the 3rd, following pretension bolt, the 4th, last pretension bolt, the 5th, packing ring, the 6th, upper bolster, the 7th, die shoe among the figure.
The specific embodiment
The concavo-convex mould of anti-cracking of compacting V-type product; Described concavo-convex mould comprises punch 1, lower cavity die 2, upper bolster 6, die shoe 7; Described going up in punch 1 and the lower cavity die 2 is respectively equipped with bolt mounting holes; Be respectively equipped with pretension bolt 4 and following pretension bolt 3 in the described bolt mounting holes, described going up on pretension bolt 4 and the following pretension bolt 3 is respectively equipped with packing ring 5.
The utility model is under the condition that guarantees concavo-convex model face intensity, and pretension bolt 3,4 should to guarantee farthest to increase the intensity of concavo-convex mould, improve its cracking resistance as far as possible near the V-type profile.
In order to resist bigger lateral stress, increase the intensity of pretension bolt 3,4, packing ring 5 must use and strengthen, the special packing ring 5 of thickening.
The reply screw rod heated before pretension bolt 3,4 was installed; Be installed into again after cooling in the pretension bolt installing hole,, guarantee the intensity of pretension bolt 3,4 to reduce the internal stress of screw rod; Thereby can the better protection mould, prolong the service life of compacting the utility model.
