Abstract
The invention relates to a flanging die which is used for a workpiece with a U-shaped end, the flanging die comprises a lower template and an upper template; the upper surface of the lower template is connected with a convex die; the lower surface of the upper template is connected with a positioning block; a material pressing device suspends on the upper template; a pressing spring is contacted with the material pressing device; the lower surface of the material pressing device is corresponding to the upper surface of the convex die; the flanging die is characterized in that a driving block is arranged on the lower template and has a certain distance from the right side of the convex die; a flanging cutter block is connected on the upper template; a recovery spring is arranged at the right part of the positioning block; the right end of the recovery spring is closely abutted against the left side of the upper part of the flanging cutter block; a balance block is connected on the upper template; the left side of the lower part of the balance block is contacted with the right side of the driving block. The flanging die has the advantages that three edges can be turned at the same time by the rotation of the flanging cutter block, the requirement of punching production can be met, the volume is small and the cost is low.
Description
Technical field
The present invention relates to a kind of flanging die, be specifically related to the flanging die of " U " shape termination workpiece of a kind of being used for.
Background technology
At present, Chang Yong flanging die is positive flanging die.The flange cutter piece of the mould of this form is fixed on the upper bolster, from just carrying out flange in the face of workpiece.But for the end flange with " U " shape termination workpiece, owing to there is the flange of three directions, if adopt the mould structure of positive flange, then can cause flange of poor quality, especially dual-side flange fillet is inconsistent.If the standard of employing wedge turns over from the side, then mould structure complexity, bulky, and wedge price is more expensive, and die cost increases, and is unfavorable for controlling cost.
Summary of the invention
The purpose of this invention is to provide a kind of flanging die that is used to have " U " shape termination workpiece, can finish three flange in " U " shape workpiece termination simultaneously, and the mould volume is little, cost is low.
A kind of flanging die that is used to have " U " shape termination workpiece of the present invention, comprise lower bolster and cope match-plate pattern, punch has been located by connecting on lower bolster, locating piece has been located by connecting below cope match-plate pattern, corresponding with locating piece above eccentric swage is suspended on the cope match-plate pattern by the discharging screw, the lower end of binder spring that is located at the middle part of locating piece contacts with the top of eccentric swage, and the following and punch of eccentric swage top corresponding is characterized in that:
One drive block is located on the lower bolster, maintain at interval with the right side of punch, the lower right side of drive block be located on the lower bolster key near;
One flange cutter piece is located by connecting on the cope match-plate pattern by axle, and the width of flange cutter piece is slightly less than the interval between drive block and the punch, and the angle of inclination on the right, flange cutter piece lower end is consistent with the angle of inclination in the drive block upper left corner;
One back-moving spring is located at the right part of locating piece, the left side on the right-hand member of back-moving spring and flange cutter piece top near;
One balance weight is located by connecting on the cope match-plate pattern, and the left side of its underpart contacts with the right side of drive block.
The present invention compares with prior art and has the following advantages: rely on the rotation of flange cutter piece, realize turning over simultaneously the purpose on three limits; This flange body can satisfy the requirement of punching production, and it is little to have a mould volume, the characteristics that cost is low.

Fig. 2 is the shape schematic diagram behind the flange of " U " shape workpiece termination.
Fig. 3 is a user mode schematic diagram of the present invention.
Fig. 4 is the shape figure of flange cutter piece.
The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Referring to Fig. 3 and Fig. 4, the present invention includes lower bolster 1 and cope match-plate pattern 6, punch 14 has been located by connecting on lower bolster, locating piece 10 has been located by connecting below cope match-plate pattern, corresponding with locating piece above eccentric swage 12 is suspended on the cope match-plate pattern by discharging screw 11, the lower end of binder spring 9 that is located at the middle part of locating piece contacts with the top of eccentric swage, and the effect of binder spring provides pressure-plate-force, the following and punch 14 of eccentric swage 12 top corresponding; One drive block 3 is located on the lower bolster 1, maintain at interval with the right side of punch 14, the lower right side of drive block be located on the lower bolster 1 key 2 near, key 2 plays the effect of the side force of location drive block 3 and balance drive block 5; One flange cutter piece 4 is located by connecting on the cope match-plate pattern 6 by axle 7, the width of flange cutter piece is slightly less than the interval between drive block and the punch, the angle of inclination on the right, flange cutter piece lower end is consistent with the angle of inclination in the drive block upper left corner, when mould is in open mode, it is fixed under the effect of the back-moving spring 8 on the eccentric swage 12, is in position shown in the dotted line among Fig. 3.Be fixed on balance weight 5 on the cope match-plate pattern 6 and play the effect of balance patrix flange side force; One back-moving spring 8 is located at the right part of locating piece 10, the left side on the right-hand member of back-moving spring and flange cutter piece 4 tops near; One balance weight 5 is located by connecting on the cope match-plate pattern 6, and the left side of its underpart contacts with the right side of drive block 3.
During flange, workpiece 13 is placed on the flanging die 14, patrix 6 is descending, and eccentric swage 12 is pushed down workpiece, and flange cutter piece 4 contacts with drive block 3, and following to anticlockwise about drive block 3, and shape the most shown in Figure 1 is pressed into part shape shown in Figure 2.
