Abstract
The utility model provides a latch for a drop arm hot forging die. An upper forming die is fastened onto a lower forming die, an upper die recess is arranged on a contact face of the upper forming die with the lower forming die, a guide post is arranged in the upper die recess, the bottom of the guide post extends out of the upper die recess, a stepped hole is arranged in the center of the top of the upper die recess, a screw is arranged in the stepped hole, the guide post is fixed inside the upper die recess through the screw, a lower die recess is arranged on the lower forming die at a position corresponding to the upper die recess of the upper forming die, and the bottom of the guide post is fixed inside the lower die recess. When the latch for the drop arm hot forging die is used, the round guide post is tightly and fittingly mounted in the round recess of the upper forming die and fastened through the screw, the round guide post is fitted with the round recess of the lower forming die to realize the latching function so as to balance dislocating force. Production practice shows that a split guide post latch designed by the method enables effective size of a drop arm hot forging die block in the thickness direction to be reduced, machining time to be shortened and machining cost of a single die to be effectively reduced.
Description
Technical field
The utility model relates to a kind of mould, especially a kind of plumbing arm hot forged mould snap close.
Background technology
Though the hotdie forging press structure has good guider; Because there is drop in arm class design of part; Make that the die joint of forging is the inclined-plane, when the center of curved surface or forging die and the center offset of impression are big, in forging process; Mould also can receive the effect of the bigger side force that metal produces in deformation process except that the forging force that receives the normal beating position of equipment.This side force can cause upper and lower mould to offset, and increases the offsetting tendency of forging, is to cause forging to produce interlayer, and is folding, the key factor of defectives such as mismatch.Huge side force also can cause damage to forging equipment and mould bases, so when carrying out design of forging die, need the method for its offsetting power of reasonable consideration balance.It is one of method of balance forging die offsetting power that employing is provided with snap close.
Traditional forging die snap close commonly used is as shown in Figure 1, and snap close and mould are that monoblock type is made up of moulding counterdie 1, moulding patrix 2 and snap close 3, and snap close and die ontology are integral structure.The protruding snap close of processing processes recessed snap close on the basis of moulding counterdie die body on the basis of moulding patrix die body, utilizes contacting of the protruding snap close of moulding patrix and the recessed snap close of moulding counterdie side, realizes leading, balance offsetting power.Like this, snap close and body are monolithic construction, and lock catch part exceeds the die ontology size and is generally 25-50mm, cause the waste of module material acquisition cost and processing cost serious.
Summary of the invention
The purpose of the utility model provides a kind of plumbing arm hot forged mould snap close, through changing the structure of Die lock catch, reaches the purpose of the manufacturing cost that reduces mould.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is following: a kind of plumbing arm hot forged mould snap close comprises moulding patrix, moulding counterdie; The moulding patrix is buckled on the moulding counterdie, it is characterized in that: contacted of said moulding patrix and moulding counterdie are provided with the patrix groove, are provided with guide pillar in the patrix groove; Stretch out in the patrix groove bottom of guide pillar; The top center of patrix groove is provided with stepped hole, is provided with screw in the stepped hole, and guide pillar is fixed in the patrix groove through screw; The position that the moulding counterdie is corresponding with the patrix groove of moulding patrix is provided with the counterdie groove, and the bottom of guide pillar is fixed in the groove.
Improvement to technique scheme: said guide pillar is cylindrical, and patrix groove and counterdie groove are and the suitable cylindrical groove of guide pillar profile.
Further improvement to technique scheme: said patrix groove is the cylinder shape groove of diameter dimension greater than guide pillar diameter 0.3mm, and the counterdie groove is the cylinder shape groove greater than guide pillar diameter 0.63mm.
Beneficial effect:
Use the described a kind of plumbing arm hot forged mould snap close of the utility model; Circular guide pillar tight fit is packed in the circular groove of moulding patrix; And it is fastening to utilize screw to carry out, and utilizes circular guide pillar and cooperating of moulding counterdie circular groove to realize snap close function, balance offsetting power.Through producing checking, according to said method the split type guide pillar buckle structure of design reduces the effective thickness direction size of plumbing arm forge hot module, and machining period shortens, and effectively reduces the processing cost of single mold.
Description of drawings
Fig. 1 is the structural representation of traditional forging die snap close.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
A kind of plumbing arm hot forged mould of the utility model as shown in Figure 2 snap close comprises moulding patrix 1, moulding counterdie 2, and moulding patrix 1 is buckled on the moulding counterdie 2; Said moulding patrix 1 is provided with the patrix groove with 2 contacted of moulding counterdies; Be provided with guide pillar 3 in the patrix groove, stretch out in the patrix groove bottom of guide pillar 3, and the top center of patrix groove is provided with stepped hole; Be provided with screw 4 in the stepped hole; Guide pillar 3 is fixed in the patrix groove through screw 4, and the position that moulding counterdie 2 is corresponding with the patrix groove of moulding patrix 1 is provided with the counterdie groove, and the bottom of guide pillar 3 is fixed in the groove.
Claims (3)
