Abstract
The invention discloses a composite die for forging an automobile crankshaft. The composite die can realize hot correction in a forged crankshaft trimming process and comprises an upper die base (1), an unloading plate (2), an upper correction die (3), an upper correction die fixing plate (4), a lower die base (5), a female die (6), a lower correction die (7), a lower correction die fixing plate (8) and elastic pieces (9), wherein the upper die base (1) is connected with the lower die base (5) through a pin; the upper correction die fixing plate (4) is mounted on the upper die base (1), the unloading plate (2) is arranged on the upper correction die fixing plate (4), and the upper correction die (3) is arranged in the unloading plate (2); the elastic pieces (9) are arranged in the lower die base (5) facing the upper die base (1), the lower correction die fixing plate (8) is arranged on the elastic pieces (9), the lower correction die (7) is arranged on the lower correction die fixing plate (8), the female die is arranged on the periphery of the lower correction die (7). According to the components, a process for forging the automobile crankshaft is shortened, the production efficiency is improved, and investment is saved.
Description
Technical field
The present invention relates to Forging Technology technology, specifically a kind of automobile crane forging compound die tool.
Background technology
More and more steel components adopts forging processing at present, cuts overlap process cause forging to be out of shape due to forging, needs to increase thermal recalibration operation, also just means and need increase equipment to carry out thermal recalibration.Along with the increase of output, cause the waste of a large amount of man-hours, energy consumption, equipment etc.
Summary of the invention
The object of this invention is to provide one trimming, thermal recalibration are combined, the automobile crane forging compound die tool that energy investment reduction, shortening technique Distance geometry are enhanced productivity.
For achieving the above object, the technical solution used in the present invention is:
A kind of automobile crane forging compound die tool, by upper bolster, stripper, correction patrix, correction upper mould fixed plate, die shoe, die, correction counterdie, correction counterdie fixed head, elastic component composition.Upper bolster is connected with die shoe by pin.Upper bolster is provided with correction upper mould fixed plate, corrects on upper mould fixed plate and be provided with stripper, in stripper, be provided with correction patrix.Being provided with elastic component in the die shoe of upper bolster, elastic component being provided with and correcting counterdie fixed head, correction counterdie fixed head is provided with correction counterdie, and correction counterdie periphery is provided with die, and die is fixed on die shoe.
Correct patrix to be connected with correction upper mould fixed plate by bolt;
Correct counterdie to be connected with correction counterdie fixed head by bolt;
Correct counterdie fixed head to be connected with die shoe by elastic component.
After adopting this structure, owing to being provided with the die with trimming effect on die shoe, correction counterdie is provided with in die, on the upper bolster of die shoe, be provided with correction upper mould fixed plate, correct on upper mould fixed plate and be provided with stripper, in stripper, be provided with correction patrix, thus the object that trimming, thermal recalibration twice technique complete by realization on operation equipment, shorten technique distance, improve production efficiency, also save investment.
Accompanying drawing explanation
Fig. 1 is the sectional view that automobile crane forging compound die tool master of the present invention looks.
Detailed description of the invention
As shown in Figure 1, automobile crane forging compound die tool of the present invention, by upper bolster 1, stripper 2, correction patrix 3, correction upper mould fixed plate 4, die shoe 5, die 6, correction counterdie 7, correction counterdie fixed head 8, elastic component 9 form.Upper bolster 1 is connected with die shoe 6 by pin.Upper bolster 1 is provided with and corrects upper mould fixed plate 4, correct on upper mould fixed plate 4 and be provided with stripper 2, be provided with in stripper 2 and correct patrix 3.Being provided with elastic component 9 in the die shoe 6 of upper bolster 1, elastic component 9 being provided with and correcting counterdie fixed head 8, correction counterdie fixed head 8 is provided with and corrects counterdie 7, correction counterdie 7 periphery is provided with die 6, and die 6 is fixed on die shoe 6.Ensure that automobile crane forging is in trimming process by above assembly, correct patrix 3 and correct counterdie 7 all the time to forging apply by elastic component 10 compress the pressure that formed, ensure that in trimming process, forging is without distortion, while also play the effect of thermal recalibration.
