Abstract
The invention relates to a beveling-flanging compound knife block mechanism. The knife block mechanism has the structure as follows: an upper die seat is downwards provided with a beveling drive block, a lower die seat is upwards provided with a flanging insert block, the profile of the flanging insert block at one side of a convex die is matched with the shape of the flanging section of a part to be machined; a limit surface of the upper end of the flanging insert block is provided with a pressing block which moves horizontally on the limit surface, a rolling profile surface sequentially formed by the pressing block and the flanging insert block is matched with the shape of the flanging section of the part to be machined. The beveling drive block presses the pressing block, which causes the pressing block to also tightly press the place close to the flanging section on the part to be machined. By cooperating with a flanging reshaping insert block to complete the flanging process, the deformation of the cover part can be effectively avoided. The mechanism has the advantages of simple operation, reducing debugging time and shortening the manufacturing cycle of dies.
Description
Technical field
The present invention relates to a kind of inclined cut flanging compound knife block mechanism.
Background technology
The quality of automobile body covering piece has often directly determined the height of a vehicle presentation quality; Obtain the target that high-quality body outer skin is each automobile vendor; Yet,, directly cause product after punching press is accomplished, to produce blemish such as distortion because of reasons such as the mould structure design are unreasonable many times; Even a large amount of debugging and rectification through the later stage often also can't reach satisfied surface quality.
The inclined cut flanging structure of present disclosed use on mould, like Fig. 1,2, shown in 3, Fig. 1,2,3 is respectively before the binder, during binder and the working state schematic representation during flange.This inclined cut flanging structure mainly comprises binder core A and flange insert B; Position on the panel beating product of flange insert B correspondence is for treating the flange position; When binder; Be out of shape because binder core A near treating that the pressure-plate-force at turn-up portion bit position place is small, causes flange insert B in the process of flange, this place to be produced, the presentation quality of vehicle body is impacted.
Summary of the invention
The object of the present invention is to provide a kind of inclined cut flanging compound knife block mechanism that can fully compress on the parts to be processed near the position of turn-up portion.
For realizing above-mentioned purpose; A kind of inclined cut flanging compound knife block mechanism provided by the invention, upper bolster are provided with one downwards and tiltedly carve drive block, and a flange insert upwards is set on the die shoe; Flange insert is positioned at the profile of punch one side and the turn-up portion shape of parts to be processed is coincide; On the confined planes of described flange insert upper end briquetting is set, briquetting translation on this confined planes, the postpone turn-up portion shape of the calendering contoured surface that constitutes and parts to be processed of briquetting and flange insert is identical.
The present invention compresses briquetting through tiltedly carving drive block, makes briquetting further compress on the parts to be processed position near turn-up portion, cooperates the flanging and restriking completion overturning process of inserting.The present invention can avoid the covering distortion effectively, and is simple to operate, reduced debug time, practiced thrift the manufacturing cycle of mould.

The specific embodiment
A kind of inclined cut flanging compound knife block mechanism, upper bolster 11 are provided with one downwards and tiltedly carve drive block 31, and a flange insert 34 upwards is set on the die shoe 21; Flange insert 34 is positioned at the profile of punch 22 1 sides and the turn-up portion shape of parts to be processed is coincide; Described tiltedly carving between drive block 31 and flange insert 34 inclined-planes respect to one another is provided with transition block 32, and transition block 32 upper ends are positioned at punch 22 1 sides briquetting 33 is set, and briquetting 33 is positioned at translation on the confined planes of flange insert 34 upper ends; Briquetting 33 and the flange insert 34 calendering contoured surface that constitutes of postponing is identical with the turn-up portion shape of parts to be processed; In the present invention, parts to be processed are panel beating product 50, and panel beating product 50 is positioned on the punch 22; As shown in Figure 4, positive apparent direction of the present invention is meant faces panel beating product 50.
In conjunction with Fig. 4; Patrix 10 is made up of upper bolster 11 and patrix briquetting 12, and counterdie 20 is made up of die shoe 21 and punch 22, between described briquetting 33 and the transition block 32 nitrogen spring 40 is set; The two flexibly connects through nitrogen spring 40; Constitute no gap between transition block 32 and the flange insert 34 and be slidingly matched, this structure can guarantee that when binder briquetting 33 fully compresses on the panel beating product 50 near the position of treating turn-up portion.
In conjunction with Fig. 4, binding face between described briquetting 33 and the flange insert 34 constitutes spigot surface, is provided with the guide plate that flange insert 34 is moved to the left along the two binding face level between flange insert 34 and the die shoe 21.
Be further described below in conjunction with Fig. 4,5,6,7,8 couples of the present invention.
When patrix 10 moves downward; Upper bolster 11 drives patrix briquetting 12 motion straight down, and as shown in Figure 4, patrix briquetting 12 at first contacts with panel beating product 50; Patrix briquetting 12 presses down panel beating product 50, and patrix briquetting 12 provides the F of pressure-plate-force straight down to panel beating product 50
1, simultaneously, upper bolster 11 drives tiltedly carves mechanism's 30 levels to left movement; Promptly drive transition block 32 by tiltedly carving drive block 31; It is oblique to left movement to drive briquetting 33 by transition block 32 again, and when briquetting 33 contacted with panel beating product 50, transition block 32 continued to left movement; And compressing briquetting 33 through compressed nitrogen spring 40, briquetting 33 provides oblique pressure-plate-force F to panel beating product 50
2, briquetting 33 is further compressed on the panel beating product 50 near the position of treating turn-up portion, as shown in Figure 5; At this moment, the shape of panel beating product 50 is referring to Fig. 7, thereafter; Flanging and restriking is inserted 34 levels to left movement, and is as shown in Figure 6, accomplishes the flanging and restriking operation; At this moment, the shape of panel beating product 50 is referring to Fig. 8.
The present invention is on the basis of patrix briquetting 12; Briquetting 33 and transition block 32 have been increased; Through transition block 32 and nitrogen spring 40 briquetting 33 is further compressed on the panel beating product 50 near treating turn-up portion bit position place; Guaranteeing provides sufficient pressure-plate-force to panel beating product 50, and the number of briquetting 33 can increase according to actual needs.In order to improve the service life of mould, insert 34 material of flanging and restriking adopts the wear-resisting alloy steel of high rigidity among the present invention, and hardens through heat treatment, and the material of briquetting 33 is that hardness is general material.
In sum; Core of the present invention is on the basis of original patrix briquetting 12; Other establishes briquetting 33; Compress panel beating product 50 through briquetting 33, on panel beating product 50,, cause panel beating product 50 in flange, to be out of shape because of suffered pressure-plate-force is not enough to avoid this position near treating that turn-up portion bit position place provides sufficient pressure-plate-force.In addition, the present invention is simple to operate, has reduced debug time, has practiced thrift the manufacturing cycle of mould.
