Description

New Trimming

Technical field

The utility model relates to a kind of diel, relates in particular to a kind of New Trimming.

Background technology

Pull and stretch is a kind of common mechanical processing technique, is the process for stamping and forming of making cup shell of the plane slab, claims again to draw.Can make the hollow object of flanged and other complicated shapes of Yuan Tong Xing ﹑ Qiu Xing ﹑ Zhui Xing ﹑ He Xing ﹑ Jie Ti Xing ﹑ by pull and stretch.Its shaping generally is to finish by Drawing Die, its oral area generally all not concordant lug can occur after drawing part is shaped, the processing of need cutting edge, it generally is to select edger for use that existing drawing part is cut edge, for some large-scale box-shaped part, sometimes need different height is cut in both sides, use existing edger can only cut a side earlier, then workpiece is taken out, the Rotate 180 degree is also adjusted the location of workpiece and is cut opposite side, working (machining) efficiency is low like this, and needs resetting, has influenced the precision of product.

Summary of the invention

At the problem that above-mentioned prior art exists, the utility model provides a kind of New Trimming, can once finish the different side cut of box-shaped part both sides height, and high efficiency has been avoided resetting, has improved the precision of product, has good practicability.

The technical solution of the utility model is: a kind of New Trimming, comprise upper bolster, die shoe and die shank, and the upper bolster lower surface is provided with guide pin bushing, and the die shoe upper surface is provided with the guide pillar that cooperates with guide pin bushing; The die shoe upper surface is provided with trim die, the trim die both sides are respectively arranged with the side cut punch, the cutting edge height difference of two side cut punch, the side cut punch is slidingly connected to the die shoe upper surface by slide block, slide block is provided with the inclined-plane away from an end of trim die, and upper bolster both sides lower surface is respectively arranged with the wedge that cooperates with the slide block inclined-plane; The position corresponding with wedge, die shoe upper surface both sides is respectively arranged with guide pad, and slide block flexibly connects by reset screw and guide pad away from an end of trim die, is socketed with the rubber blanket that resets on the screw that resets.

As preferably, the position that upper bolster is corresponding with trim die is provided with pull bar, and the pull bar lower end is connected with holding pad, and the upper end is slidingly connected in the die shank, is socketed with the binder spring on the pull bar between holding pad and the upper bolster.

As preferably, be provided with slide plate between slide block and the die shoe, be rounded down respectively on the face that guide pad and wedge are fitted to each other, reset screw and guide pad matched in clearance, guide pad has half groove away from an end of slide block, and the rubber blanket that resets is positioned at half groove.

The beneficial effects of the utility model are: the utility model trim die both sides are respectively arranged with the different side cut punch of cutting edge height, adding the man-hour upper bolster moves down, the wedge of both sides moves the side cut punch of both sides respectively to the direction near trim die, finish the different side cut of box-like workpiece height, the working (machining) efficiency height, workpiece need not take off from trim die, has avoided resetting, has improved the product precision.Holding pad can workpiece pressing under the effect of binder spring, has guaranteed the positional precision of workpiece, has good practicability.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of New Trimming, comprise upper bolster 6, die shoe 2 and die shank 8, upper bolster 6 lower surfaces are provided with guide pin bushing, die shoe 2 upper surfaces are provided with the guide pillar that cooperates with guide pin bushing, have improved the guiding accuracy (guide pin bushing and guide pillar all do not draw among the figure) of the utility model motion.Die shoe 2 upper surfaces are provided with trim die 11, and as preferably, trim die 11 is up big and down small stairstepping, makes things convenient for the location of workpiece.Trim die 11 both sides are respectively arranged with the cutting edge height difference of 12, two side cut punch 12 of side cut punch, and as preferably, the cutting edge place of side cut punch 12 is provided with the oblique angle, leak under the convenient waste material of cutting edge.Side cut punch 12 is slidingly connected to die shoe 2 upper surfaces by slide block 13, as preferably, slide block 13 is the L shaped of traverse, and slide block 13 is provided with the inclined-plane away from an end of trim die 11, and upper bolster 6 both sides lower surfaces are respectively arranged with the wedge 5 that cooperates with slide block 13 inclined-planes; Die shoe 2 upper surface both sides and wedge 5 corresponding positions are respectively arranged with guide pad 14, and in the present embodiment, guide pad 14 is triangular fin.Slide block 13 flexibly connects with guide pad 14 by the screw 3 that resets away from an end of trim die 11, is socketed with the rubber blanket 4 that resets on the screw 3 that resets.The nut encapsulation of rubber blanket 4 by screw 3 ends that reset resets.Guide pad 14 punch 12 that can help to cut edge resets, and can also be wedge 5 guiding, improves the kinematic accuracy of wedge 5.
