Abstract

The utility model provides an insert die of an electro-hydraulic die forging hammer. The insert die of the electro-hydraulic die forging hammer comprises an upper die body and a lower die body, wherein an upper insert block is embedded in the upper die body, a lower insert block is embedded in the lower die body, a forming cavity is formed between the upper insert block and the lower insert block, a flash bridge portion is arranged outside the forming cavity between the upper insert block and the lower insert block, the flash bridge portion is further connected with a bin portion, and the flash bridge portion, the bin portion, the upper insert block, the lower insert block and the forming cavity form a whole. According to the insert die of the electro-hydraulic die forging hammer, in a production process, the whole formed by the flash bridge portion, the bin portion, the upper insert block, the lower insert block and the forming cavity is utilized, and therefore die cost amortization is enabled to decrease by more than 70%; and compared with a traditional insert die, the improved insert die has a broader application scope, products which can only be produced through an integrated die before can be used continuously in the novel insert die, the size of the die is reduced, the application scope is expanded, and production cost is lowered.

Description

The insert die of electricity liquid die hammer
Technical field
The utility model relates to the mould of forging industry, is applicable to friction press forging, hotdie forging press forging etc., specifically the insert die of electric liquid die hammer.
Background technology
3 tons and 5 tons of electric liquid die hammers, the main circumgyrating forgings such as gear blank of producing all size, the mould structure of traditional die hammer is mainly monoblock type and block insert type, the mould for forging of producing is mostly adopted the monoblock type forging die, as shown in Figure 1, 2, all on insert die, the size that forges like this product is subjected to the impact of insert die size just to have certain limitation for the die cavity of product, overlap bridge section and die cavity storehouse section, just can not use in case die cavity storehouse section size surpasses the size of inserting.
Because monoblock type hammer forging die size is larger, one set of modules weight is about 1.6 tons, only mold materials expense just reaches several ten thousand yuan, and it is all very high to add monoblock type forging die processing charges and heat treatment expense, and the price of the mold that gets off like this is just very expensive, cause production cost high, product lacks market competitive power, and block insert type has the mold materials of saving, makes simple, low cost and other advantages, and shortcoming is to open the blocking die cavity at insert die, forging is easy to produce folding, causes product rejection; And this traditional insert die just compares with solid forging die and has advantage, also exists a lot of shortcomings, and the scope of application is restricted, and production cost is still higher.
Summary of the invention
The utility model is in order to save the folding problem of mold materials, reduction cost and solution product, the special insert die that proposes electric liquid die hammer.
The technical solution of the utility model is for this reason, the insert die of electricity liquid die hammer, comprise upper die body and lower mold body, stud with on the upper die body and insert, lower mold body is provided with down inserts, on insert and under be provided with die cavity between inserting, it is characterized in that: insert and under be provided with overlap bridge section outside the die cavity between inserting, overlap bridge section is being connected with storehouse section, overlap bridge section, storehouse section and on insert, insert down and die cavity forms an integral body.
Beneficial effect:
The utility model utilize aborning overlap bridge section, storehouse section and on insert, insert down and integral body that die cavity forms, the die cost stand is disappeared to have reduced more than 70%, insert die after the improvement, more traditional insert die has enlarged the scope of application, made originally and must can continue to have used at this novel insert die again at the product that whole mould is produced, reduce die size, enlarge range of application, reduced production cost.

Fig. 2 is the enlarged diagram that A is ordered among Fig. 1.
Fig. 3 is the structural representation of the utility model die insert.
Fig. 4 is the enlarged diagram that B is ordered among Fig. 3.
1 is upper die body among the figure, the 2nd, on insert, the 3rd, lower mold body, the 4th, lower inserting, the 5th, storehouse section, the 6th, overlap bridge section, the 7th, die cavity.
The specific embodiment
The utility model is shown in Fig. 3,4.
The insert die of electricity liquid die hammer, comprise upper die body 1 and lower mold body 3, stud with on the upper die body 1 and insert 2, lower mold body 3 is provided with down inserts 4, on insert 2 and under insert and be provided with die cavity 7 between 4, be insert 2 and under insert and be provided with overlap bridge section 6 between 4 outside the die cavity 7, overlap bridge section 6 is being connected with storehouse section 5, overlap bridge section 6, storehouse section 5 and on insert 2, insert down 4 and die cavity 7 form an integral body.
Insert die structure after the improvement makes die cavity 7, overlap bridge section 6 and the storehouse section 5 of product all on insert die, make and to adopt traditional insert die can use at this novel insert die again at the product that whole mould is produced, more traditional insert die has enlarged the scope of application, has reduced production cost.
