Abstract
The invention relates to a crack-proof punch and die set for pressing a V-shaped part. The concave-convex die comprises an upper convex die, a lower concave die, an upper die seat and a lower die seat. Bolt mounting holes are reserved on the upper convex die and the lower concave die respectively. An upper preloaded bolt and a lower preloaded bolt are disposed on the bolt mounting holes respectively. Gaskets are disposed on the upper preloaded bolt and the lower preloaded bolt respectively. The crack-proof concave-convex die for pressing the V-shaped part has the advantages that mounting and debugging of a retaining wall whenever the die is mounted is avoided, work strength of an operator is relieved, and production efficiency is improved; excessive wastage and even damage of the die due to untight fitting of the die seat with the retaining wall are avoided effectively; strength of the die is increased effectively, and crack of the die is prevented in advance; and the crack-proof concave-convex die is simple in structure, easy to manufacture, free of constant dismounting, and high in strength.
Description
Technical field
The present invention relates to a kind of diel, relate 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.
Summary of the invention
The present invention 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.
Technical scheme of the present invention 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 invention has the beneficial effects as follows: 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 present invention has avoided cooperating excessive loss even the damage that does not closely cause mould with die holder because of barricade effectively; 3, the present invention has fundamentally increased the intensity of mould itself, has prevented the cracking of mould in advance; 4, the present invention 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 a structural representation of the present invention.
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
A kind of concavo-convex mould of anti-cracking of suppressing the 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 present invention 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 rods heated before pretension bolt 3,4 was installed, and were installed into after cooling in the pretension bolt installing hole again, to reduce the internal stress of screw rod, guaranteed the intensity of pretension bolt 3,4, thereby can the better protection mould, prolonged compacting service life of the present invention.
