Description

Suspension bracket for car engine manufacture method and die for manufacturing thereof
Technical field
The present invention relates to mechanical field, be specifically related to a kind of suspension bracket for car engine manufacture method and die for manufacturing thereof.
Background technology
At present, engine mounting bracing frame flawless and without the attenuate amount (attenuate amount<thickness of slab * 15%) that exceeds standard when guaranteeing punch forming usually sets up mount supports and counts symmetrical structure.Steel plate is stressed evenly in the time of can guaranteeing punching press like this, can effectively avoid avulsion and attenuate risk.But in the practice process, because dodging part on every side, during perhaps in conjunction with car body inside unique design, needing this support Design be unsymmetric structure, but the bracing frame of unsymmetric structure because of when the punching press, unbalance stress, be difficult to moulding, easy cracking and at the bending part attenuate, thereby do not reach designing requirement, can not satisfy the development need of automotive engineering.
Summary of the invention
The present invention aims to provide a kind of suspension bracket for car engine manufacture method and die for manufacturing thereof, uses the machine-shaping problem that the method and mould can solve the unsymmetric structure mould.
Suspension bracket for car engine die for manufacturing of the present invention comprises upper die and lower die and base, and floor installation has counterdie and lead, on patrix installation and the lead, do bottom and top feed along lead and move, die is installed on the patrix, punch is installed on the counterdie; Also include ejection block, be connected by many foundation seat spring between ejection block and the base, the centre of ejection block is provided with the cavity that matches with punch, when the base spring is in free state, punch integral body is among the cavity, and the upper surface of ejection block is mutually corresponding with the shape of the lower surface of die; When patrix was depressed, contact and drive ejection block were done feed motion downwards, and the base spring is compressed, exposes punch, and punch is cooperated with die.
Described ejection block is provided with locating module.
Described locating module is three square fixed blocks and columniform fixed leg that is in triangular distribution, and fixed leg is positioned in the middle of two fixed blocks of ejection block rear side.
Suspension bracket for car engine die for manufacturing of the present invention, also comprise two liftout posts, described liftout post is connected with patrix by the post spring, and the liftout post is positioned within the die, its length is according to the shape adjustments of punch, and the stroke of post spring is consistent with distance between the upper die and lower die.
Described lead is rectangular structure, limited location cover on the patrix, and stop collar is wrapped up in lead from three bread, and the bottom and top feed motion take lead as the track restrictions patrix is in a straight line.
Use described suspension bracket for car engine die for manufacturing and make the method for suspension bracket for car engine, may further comprise the steps:
A, determine blanking block from steel plate, described blanking block comprises location circular arc and the linear gulde edge of arc, and the location circular arc is positioned at the centre of blanking block afterbody, and there is linear gulde edge the both sides of location circular arc and the front portion of blanking block;
B, blanking block is placed on the ejection block, location circular arc and gulde edge are respectively to upper fixed leg and fixed block, so that blanking block is stable, patrix is depressed under the effect of forcing press, the liftout post contacts with blanking block first, the post spring is compressed, blanking block is further spacing firm under the active force of liftout post, die contacts with blanking block and ejection block subsequently, ejection block moves down under pressure, and the base spring is compressed, progressively exposes punch, under the cooperatively interacting of die and punch, blanking block is pressed moulding; Then patrix moves upward, and ejection block remains unchanged with the relative position of patrix under the active force of post base spring, move upward with patrix, until the compression travel of base spring recovers, with the stampings top of moulding from punch; Patrix further moves upward, and the liftout post ejects die with stampings under the effect of post spring, and stampings are finished the demoulding;
C, stampings are carried out the postorder work disposal, and get final product.
Described postorder work disposal comprises carries out flange, cuts out unnecessary sheet material, punching, welding stiffener.
Suspension bracket for car engine die for manufacturing of the present invention has used ejection block and these two novel structural designs of liftout post.Ejection block adopts the spring structure design, so that overall process ejection block and the die surface of compacting are in stable associated movement state all the time, punch progressively stretches out from ejection block, progressively cooperate with die, guaranteed that blanking block stablizes moulding in whole pressing process, avoided unbalance stress and the cracking or the even problem of became uneven that cause; Simultaneously after compacting is finished, ejection block is known with the patrix interlock stampings are ejected punch stably under the naturally stretching, extension of base spring, has been avoided the distortion of ejection process stampings.Set locating module on the ejection block, in preparation blanking block process, reserve the location structure corresponding with this locating module at blanking block, this can be so that blanking block location be more accurate, and in conjunction with this new construction of liftout post, in pressing process, the liftout post touches first blanking block, blanking block further firmly is positioned then to contact stably punch on the ejection block, has guaranteed that pressing process more accurately, reliably.Ejection block has also been utilized the elastic deformation of spring, at patrix and ejection block after separating, with stampings progressively eject die, thereby realize the detach procedure of whole product.
The present invention also provides the method for utilizing this novel die to prepare suspension bracket for car engine, the method simple operation, reliable and stable, machining accuracy is high, solved the problem that prior art is difficult to process the unsymmetric structure suspension bracket for car engine, can process the unsymmetric structure suspension bracket for car engine with various radians and warp architecture, have very high practical value.
