Abstract

An angle cutting punch fixture comprises splayed left and right positioning bars, on which a fixed reinforcing plate is transversely fixed. When the angle cutting punch fixture is used, the two positioning bars are fixed on lower diehead holders, the positions of the tops of the positioning bars correspond to the position of the force plug of the punch, a workpiece is inserted into the angle cutting punch fixture and between the lower diehead holders to be clamped, and during punching, the force plug directly punches the workpiece to form round angles.

Description

Corner cut punch press anchor clamps

Technical field

The utility model relates to a kind of anchor clamps, is used for fixing the anchor clamps of workpiece on especially a kind of punch press.

Background technology

In the mould punching press, especially during mould punching press fillet, traditional operation is by manually being placed directly on the die plate, carry out punching press then, so effective fixation workpiece is especially when shearing plate, workpiece one side is subjected to big shearing force, hand is held a side and is not stressed, and the side that then do not stress can be upturned because of discontinuity, influences the workpiece product quality.

The utility model content

The purpose of this utility model provide a kind of on punch press, use can increase work efficiency, punch press anchor clamps easy and simple to handle.

For achieving the above object, the utility model adopts following technical scheme: comprise being left positioning strip and the right positioning strip that " eight " font distributes, two positioning strips are fixedly mounted on the die shoe, its tip position is corresponding with the punch position on the punch press, and promptly the little end opening in top is corresponding with circular arc mouth position on the punch.Like this workpiece be placed on below the corner cut punch press anchor clamps compacted, under punch towards the time can not interfere with anchor clamps, the descending direct stamped workpieces of punch forms fillet during punching press.

As to a kind of improvement of the present utility model, crosswise fixed is provided with the reinforcement fixed head on the left and right positioning strip of " eight " font.In punching course, prevent workpiece do not stress because of discontinuity makes the end be upturned.

As another kind of the present utility model is improved, left and right location-plate angle is 90 °.After workpiece was put into below the anchor clamps like this, the left and right positioning strip of the right-angle side of workpiece and anchor clamps can fit like a glove, and helped the location.

The specific embodiment

Fig. 1 shows the structural representation of corner cut punch press anchor clamps, comprise left positioning strip 1 and right positioning strip 2 that " eight " font distributes, crosswise fixed has the fixed head 3 of reinforcement on left and

right positioning strip

1,2, be welded to connect between left and

right positioning strip

1,2 and the reinforcement fixed head 3, left and

right positioning strip

1,2 angles are 90 °.

Fig. 2, Fig. 3 show master, the vertical view of corner cut punch press anchor clamps operation principle, corner cut punch press anchor clamps 7 are fixed on the die shoe 5, workpiece 4 is inserted between corner cut punch press anchor clamps 7 and the die shoe 5, coincide with left and

right positioning strip

1,2 limits, interference fits between workpiece 4 and the corner cut punch press anchor clamps 7, over against punch press punch 8, the open top of left and

right positioning strip

1,2 is consistent with punch circular arc 6 sizes above, and angle is 90 °; During punching press, punch 1 descending direct stamped workpieces 4 forms fillet.
