Abstract
The invention discloses a lateral trimming mechanism for automobile progressive dies. The lateral trimming mechanism is composed of a lateral trimming drive block, a lateral trimming installation plate, a lower die drive block and a lower die installation block, wherein the lateral trimming installation plate is arranged between an upper die installation plate and an upper die pressing plate; the lateral trimming drive block is vertically arranged, the upper end of the lateral trimming drive block is connected to the lateral trimming installation plate in a hinged mode through a hinged shaft, and an inclined surface is arranged at the lower end of the lateral trimming drive block; the lower die drive block is arranged on a big lower die plate, abuts against a lower die insert and is provided with an inclined surface matched with the inclined surface on the lateral trimming drive block; a flange facing the lateral trimming drive block is arranged at the part, facing the bevel of the lateral trimming drive block, at the upper end of the lower die installation block. The lateral trimming mechanism has the beneficial effects that lateral trimming can be realized, springback can be controlled, the rate of finished automobile progressive die products can be increased, the occupied space is small, the number of components is small, and the width of the whole lateral trimming mechanism is smaller than 40 millimeters. The lateral trimming mechanism can be applied to the lateral trimming area with the space limited.
Description
Technical field
The invention belongs to mechanical manufacturing field, be specifically related to plate pressure forming resilience deviation and eliminate.
Background technology
Generally there is resilience problem in sheet forming process, in BENDING PROCESS, rebound phenomenon is more serious especially.In plate shaping field, resilience has become key issue to be considered in Design of Dies.Existence due to resilience, after unloading, the geomery of part can not comply fully with the geomery of die surface, the dimensional accuracy of part does not reaches design requirement, production efficiency is caused strong influence, it is therefore necessary to the most reasonably control product resilience in mould structure to need in-depth study.
In order to control the resilience scope in flange face, traditional moulds can increase Wedge type side complete machine structure in this face.Owing to automotive grade progressive die product has material strip to connect, there is no enough space arrangement tradition Wedge mechanisms, make not have been resolved on the method for controlling springback of automotive grade progressive die product and equipment.
Summary of the invention
It is an object of the invention to provide a kind of automobile progressive die side complete machine structure, for eliminating the dimensional discrepancy that automobile shell parts plate extrusion forming resilience is formed, overcome deficiencies of the prior art.
The side complete machine structure of the present invention is arranged between mold mounting plate and the big plate of lower mold, is made up of the whole drive block in side, the whole installing plate in side, lower mold drive block, lower mold mounting blocks；Wherein, the whole installing plate in side is arranged between mold mounting plate and upper molded plate, is provided with backing plate between the whole installing plate in side and upper mold mounting plate,The whole drive block in side is vertically arranged, upper end hinge is hinged on the whole installing plate in side, the whole drive block in side is gradually to the inclined-plane of lower mold mounting blocks through the lower end of stripper from top to bottom relative to being backed with of lower mold mounting blocks, lower mold drive block falls on the big plate of lower mold, lower mold drive block is against in lower mold insert relative to the back side of lower mold mounting blocks, lower mold drive block has the inclined-plane being gradually to lower mold mounting blocks from top to bottom towards the one side upper end of lower mold mounting blocks, and the inclined-plane on the whole drive block in inclined-plane and side on lower mold drive block coincide；There is the fin of whole drive block towards side lower mold mounting blocks upper end at the knuckle of the whole drive block in side.
The operation principle of the present invention is: the whole drive block in side moves down along with board slide block, contacts lower mold drive block, and the whole drive block in side rotates around hinge, and product side carries out the shaping action more than finished product knuckle；Moving on board slide block, mould is opened, and the whole drive block in side departs from the constraint of lower mold drive block, product resilience, and the whole drive block in side resets around relatively axle.
The positive effect of the present invention is: eliminate the dimensional discrepancy that automobile shell parts plate extrusion forming resilience is formed, improving the yield rate of automotive grade progressive die product, and it is little to take up room, component is few, whole side complete machine structure, less than 40 mm wides, can be used in the territory, main plot, side of limited space.In actual applications, the position, right angle to product, after previous operation, product spring back angle is 96 degree, in the operation of the application of the invention, product breaks into 88 degree, has produced rear product and has freely sprung back to 90.5 degree, has met product requirement.
Accompanying drawing explanation
Fig. 1 is present configuration figure.
Fig. 2 is present invention installation diagram on mould.
Detailed description of the invention
Refering to Fig. 1, Fig. 2, the side complete machine structure of the present invention is arranged between mold mounting plate 4 and the big plate of lower mold 21, is made up of the whole drive block in side 5, the whole installing plate in side 8, lower mold drive block 16, lower mold mounting blocks 18；Wherein, the whole installing plate in side 8 is arranged between mold mounting plate 4 and upper molded plate 1, is provided with backing plate 7 between the whole installing plate in side and upper mold mounting plate,Side whole drive block 5 is vertically arranged, upper end hinge 6 is hinged on the whole installing plate in side 8, the whole drive block in side 5 is gradually to the inclined-plane of lower mold mounting blocks 18 through the lower end of stripper 2 from top to bottom relative to being backed with of lower mold mounting blocks 18, lower mold drive block 16 falls on the big plate of lower mold 21, the back side of the relative lower mold mounting blocks 18 of lower mold drive block 16 is against in lower mold insert 12, and the big plate of lower mold 21 is supported on lower mold backing plate 10 by feet 13,17,20.Lower mold drive block 16 has the inclined-plane being gradually to lower mold mounting blocks from top to bottom towards the one side upper end of lower mold mounting blocks 18, and the inclined-plane on the whole drive block in inclined-plane and side 5 on lower mold drive block 16 coincide；There is the fin of whole drive block 5 towards side lower mold mounting blocks upper end at the knuckle of the whole drive block in side.In Fig. 23 are upper die plate, 11 be that lower mold holds up, 14 is picking-up block, 15 is nitrogen spring, 19 is the product processed.
