Abstract
The utility model relates to a flanging die for workpiece with U-shaped end, which comprises a lower die plate and an upper die plate which is connectively provided with a terrace die, a positioning block is connected to the lower side of the upper die plate, an eccentric swage is hanged over the upper die plate, an eccentric spring is in contact with the eccentric swage, and the lower side of the eccentric swage is corresponding to the upper side of the terrace die. The flanging die for workpiece with U-shaped end is characterized in that a driven block arranged on the lower die plate holds space to the right side of the terrace die, a flanging knife block is connected on the upper die plate, an offsetting spring is arranged on the right portion of the positioning block whose right end clings to the upper left side of the flanging knife block, and the lower left side of a balancing block which is connected on the upper die plate is in contact with the driven block. The flanging die for workpiece with U-shaped end has the following advantages: depending on the rotation of the flanging knife block, the aim of turning over three sides simultaneously is realized, the flanging mechanism can satisfy the needs of punching production, moreover, the volume of the die is small, and the cost is low.
Description
Technical field
The utility model relates to a kind of flanging die, is 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.
The utility model content
The purpose of this utility model provides 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, and cost is low.
A kind of flanging die that is used to have " U " shape termination workpiece described in the utility model, 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 utility model is compared with prior art and is had 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.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 3 and Fig. 4, the utility model comprises 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.
