Abstract
The utility model discloses a tool for increasing die forging performances of friction press so disposed that the tool herein comprises a middle slide block which is provided with a lower die of a pre-forging die and a upper die of a finish forging die respectively on and under the central position of the middle sliding block, the middle sliding block being also provided with a guide sleeve. The conventional cycloidal gear forging of closed-die forging reducer usually requires pneumatic hammer of large tonnage in blank making or requires an extra forcing press combined with the pneumatic hammer in blank making. The forging of connecting rod forging for auto engines requires processing of a pre-forging cavity and a finish forging cavity on the hot-forging die module, which often leads to high cost of manufacturing hot-forging die. Each hit of hammer upon die forging will impose bias load on friction press, which often causes production cessation and maintenance. Connecting rod forgings produced by conventional friction presses tend to lead to wrong die. The utility model can solve the said problems of conventional friction press.
Description
Technical field
The utility model relates to a kind of forcing press die forging frock, especially a kind of frock that improves friction screw press die forging performance.
Background technology
At present at friction screw press precision die forging dish forging and angular wheel forging, with two friction screw press connection and production; The long axis forging of die forging section complicated shape adopts blocking, the die forging of finish-forging double mould cavity, the first hammer blocking, the second hammer finish-forging, and blocking die cavity and finish-forging die cavity be not at friction screw press slide block center.
Two friction screw press connection of above-mentioned usefulness and production have the following disadvantages:
1, equipment investment is big.
2, production efficiency is low.
3, labor intensity of operating staff height.
The die forging of above-mentioned employing double mould cavity, blocking, finish-forging die cavity do not have the following disadvantages at friction screw press slide block center:
Can not bear unbalance loading during 1, because of the friction screw press die forging, and each hammering of this technology is hit, friction screw press all bears unbalance loading, and is bigger to equipment damage.
2, defectives such as mismatch appear in forging easily in the die forging production process.
3, make hot forged mould specification requirement height, production cost height.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of minimizing equipment investment is provided, and can overcome the defective that current friction screw press can not bear unbalance loading, blocking die cavity, finish-forging die cavity are all in the frock of the raising friction screw press die forging performance at friction screw press slide block center.
For achieving the above object, the utility model adopts following technical proposals:
A kind of frock that improves friction screw press die forging performance, comprise an intermediate slider, the center of intermediate slider top and below be respectively equipped with blocker counterdie and finisher patrix, intermediate slider is provided with fairlead, is being provided with the lead that cooperates with the intermediate slider fairlead on the working plate or on the slide block yoke plate.
Originally closed die forging reductor cycloidal-pin wheel forging needs large tonnage pneumatic hammer base or increases a forcing press specially and pneumatic hammer connection and base, has increased investment in fixed assets, increases production cost, reduces production efficiency; Originally forge the connection rod of automobile engine forging, a blocking die cavity of processing, a finish-forging die cavity on the hot-forging die module, it is higher to make the hot forged mould cost, every strike one hammer of friction screw press during die forging, all bear unbalance loading, often stop production and repair facility, the forging of production is easy to occur defectives such as mismatch.Above problem obtains fine solution after adopting the utility model.
Tradition precision forging angular wheel technology is to use two friction screw press connection and produces, and reduces the investment of a friction screw press equipment behind use the utility model, and precision forging angular wheel production efficiency improves 30%.Labor intensity of operating staff reduces by 20%.
Description of drawings
Fig. 1, Fig. 2 are the utility model working state schematic representations;
1. press frames wherein, 2. workbench, 3. finisher counterdie, 4. finisher patrix, 5. intermediate slider, 6. blocker counterdie, 7. blocker patrix, 8. pull bar, 9. press ram, 10. slide block yoke plate, 11. fairleads, 12. leads.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment 1 (with 630 tons of friction screw press closed die forging reductor cycloidal-pin wheel forging is example, sees Fig. 1),
630 tons of friction screw presses with current normal use, lay down the former workbench of band at random, between press frame 1 and press ram 9, put an intermediate slider 5, the center of intermediate slider 5 top and below be respectively equipped with blocker counterdie 6 and finisher patrix 4; Intermediate slider is provided with fairlead 11; 12 pairs of middle slide block 5 guiding of lead are installed on workbench 2; Pull bar 8 upper ends and slide block yoke plate 10 link, the lower end is fixed on the intermediate slider 5 by nut, are used for promoting intermediate slider 5; Blocker patrix 7 is fixed on the friction screw press slide block 9; Finisher counterdie 3 is fixed on the workbench 2.
Take out cycloidal-pin wheel blocking forging from blocker 6 and be placed in the die cavity of finisher counterdie 3, pneumatic hammer jumping-up, the cycloidal-pin wheel forging blank after descaling are placed in the die cavity of blocker counterdie 6; 630 tons of friction screw presses hit, and blocker and finisher are worked simultaneously; The cycloidal-pin wheel forging that takes out from finisher dashes the connection skin, and the cycloidal-pin wheel blocking forging that takes out from blocker is put in the finisher counterdie 3 again, waits for the strike of next hammer.
Embodiment 2 (with 1000 tons of friction screw press die forging connection rod of automobile engine is example, sees Fig. 2)
12 pairs of middle slide block 5 guiding of lead are installed on slide block yoke plate 10.
The connection rod of automobile engine blocking forging that takes out from blocker 6 is placed in the die cavity of finisher counterdie 3, and the connection rod of automobile engine forging blank of roll forging machine base is placed in the die cavity of blocker counterdie 6; 1000 tons of friction screw presses hit, the die forging simultaneously of blocker and finisher; Cut overlap from the connection rod of automobile engine forging that finisher takes out, the connection rod of automobile engine blocking forging that takes out from blocker is put in the finisher counterdie 3 again, waits for the strike of next hammer.
When friction screw press manufacture order die cavity forging, lay down intermediate slider 5, workbench 2, install former friction screw press workbench, reply friction screw press all functions in the past.
Embodiment recited above; only be that preferred implementation of the present utility model is described; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians are to the technical solution of the utility model in this area; various modification and the improvement made all should fall into protection domain of the present utility model.
