Description

Technical Field

[0001] The present invention relates to the technical field of presses, and more particularly, to a forging die holder for realizing rapid switching of inserts. Background Art

[0002] In general, combined forging dies composed of a general die holder and insert dies are used for open-die forging on large-tonnage presses to save the production cost of dies. Large-tonnage presses are generally equipped with more than two sets of general die holders, such as a plate-type general die holder and a key-type general die holder, for the installation and use of insert dies with different lengths and specifications. The plate-type general die holder is used for the installation of short insert dies to produce forgings such as gears and squares; the key-type general die holder is used for the installation of long insert dies to produce forgings such as long rods. A large-tonnage press equipped with two sets of general die holders will result in high investment costs. Moreover, to meet the production schedules of different products, it is necessary to alternately use the two sets of general die holders on the press, which requires frequent disassembly and installation of the die bases, consuming a large amount of time, manpower, and material resources. In addition, the press equipment will be damaged to a certain extent during the installation process, affecting its accuracy. Summary of the Invention

[0003] In view of the above technical problems such as high costs caused by the use of more than two sets of general die holders in existing presses and equipment damage and accuracy reduction caused by alternating the use of die holders, a forging die holder for realizing rapid switching of inserts is provided, which can conveniently replace insert dies with different lengths and sizes. During the production of the press, there is no need to replace the die bases back and forth, saving manpower and material resources and achieving the purpose of cost reduction and efficiency improvement.

[0004] The technical means adopted by the present invention are as follows:

[0005] A forging die holder for realizing rapid switching of inserts, comprising an upper top plate, a die base, a backing plate, and an intermediate die base;

[0006] The upper top plate and the die base are respectively provided with grooves, and the backing plate and the intermediate die base are detachably installed in the grooves;

[0007] The backing plate is used for installing long inserts, and both ends of the long insert are respectively provided with pressure blocks, and the pressure blocks are detachably installed on the backing plate;

[0008] The intermediate die base is used for installing short inserts. The intermediate die base includes an insert limiting part and a die base connecting part arranged up and down; the die base connecting part has the same shape and size as the backing plate and is detachably connected to the groove; the insert limiting part forms a short insert installation space for installing the short insert on the die base connecting part, and an inclined surface pressing plate is arranged on one side of the short insert, and the inclined surface pressing plate is detachably installed on the die base connecting part.

[0009] Further, the backing plate is detachably mounted in the groove by a T-bolt and a nut; the groove is provided with a T-slot, and both ends of the backing plate are provided with fixing slots I corresponding to the position of the T-slot. The T-bolt is mounted in the T-slot and the fixing slot I, and the pressing block is detachably mounted on the top of the T-bolt, thereby realizing the connection between the long insert block and the backing plate.

[0010] Further, pressing block mounting grooves are respectively arranged at both ends of the long insert block, and a part of the pressing block is mounted in the pressing block mounting groove.

[0011] Further, a plurality of key grooves are arranged on the surface of the backing plate, and the long insert block is positioned on the backing plate and the installation position is adjusted by keys mounted in the key grooves.

[0012] Further, the intermediate die base is detachably mounted in the groove by a T-bolt and a nut; the groove is provided with a T-slot, and both ends of the die base connecting part are provided with fixing slots II corresponding to the position of the T-slot. The T-bolt is mounted in the T-slot and the fixing slot II.

[0013] Further, the inner surface of the insert block limiting part matches the side surface of the short insert block. When the short insert block is mounted in the short insert block installation space, the side surface of the short insert block can be closely attached to the inner surface of the insert block limiting part.

[0014] Further, the inclined surface pressing plate is detachably mounted on the die base connecting part by bolts. The die base connecting part is provided with a pressing plate mounting groove, and the bottom of the inclined surface pressing plate is mounted in the pressing plate mounting groove.

[0015] Further, when the long insert block is mounted on the forging die set, one backing plate is mounted in each of the grooves of the upper top plate and the die base; when the short insert block is mounted on the forging die set, one intermediate die base is mounted in each of the grooves of the upper top plate and the die base.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The forging die set provided by the present invention for realizing the quick replacement of insert blocks can conveniently replace insert block dies of different sizes of long and short types, and there is no need to replace the die base back and forth during the production and use of the press, saving the die base manufacturing cost and the working time required for replacing the die base for large-tonnage presses.

[0018] 2. The forging die set provided by the present invention for realizing the rapid switching of inserts has a semi-open intermediate die base structure. On the premise of ensuring strength, it maximally increases the convenience of loading and unloading insert dies and avoids the jamming of the dies caused by thermal expansion. At the same time, the intermediate die base uses a quenched backing plate to prevent indentations from being pressed out on the supporting surface of the die base. The quenched backing plate is small in size, simple in structure, and low in replacement cost during production.

[0019] For the above reasons, the present invention can be widely promoted in the technical field of presses. BRIEF DESCRIPTION OF THE DRAWINGS

The die base connecting part 42 has the same shape and size as the backing plate 3 and is detachably connected to the groove 5. The insert limiting part 41 forms a short insert mounting space 43 for mounting the short insert 8 on the die base connecting part 42. A beveled pressing plate 9 is arranged on one side of the short insert 8, and the beveled pressing plate 9 is detachably mounted on the die base connecting part 42.

[0038] Further, the backing plate 3 is detachably mounted in the groove 5 by T-bolts and nuts; the groove is provided with a T-slot 10, and both ends of the backing plate 3 are provided with fixing grooves Ⅰ corresponding to the position of the T-slot 10. The T-bolts are mounted in the T-slot 10 and the fixing grooves Ⅰ, and the pressing block 7 is detachably mounted on the top of the T-bolts, thereby realizing the connection between the long insert 6 and the backing plate 3.

[0039] Further, by adjusting the mounting position of the pressing block 7 on the backing plate 3, the mounting position of the long insert 6 on the backing plate 3 can be adjusted.

[0040] Further, both ends of the long insert 6 are respectively provided with pressing block mounting grooves, and a part of the pressing block 7 is mounted in the pressing block mounting grooves.

[0041] Further, a plurality of key grooves are provided on the surface of the backing plate 3, and key grooves are also provided on the bottom surface of the long insert 6. The long insert 6 is positioned and the mounting position is adjusted on the backing plate 3 by keys 11 mounted in the key grooves.

[0042] Further, the backing plate 3 and the long insert 6 are provided with key grooves arranged in a cross shape, which can position the long insert 6 in all directions of front, back, left and right.

[0043] Further, the backing plate 3 is a quenched backing plate, and the replacement cost in production is low.

[0044] Further, the intermediate die base 4 is detachably mounted in the groove 5 by T-bolts and nuts; the groove 5 is provided with a T-slot 10, and both ends of the die base connecting portion 42 are provided with fixing grooves Ⅱ corresponding to the position of the T-slot 10.
