Abstract
The utility model discloses a flange trimming die, and relates to a stamping die. The flange trimming die comprises an upper die seat, a die handle and a lower die seat, wherein a trimming male die is arranged on the upper surface of the lower die seat; a trimming female die is arranged at a position, which is opposite to the trimming male die, on the lower surface of the upper die seat; a positioning boss is arranged on the upper surface of the trimming male die; two waste material cutters are symmetrically arranged on the upper surface of the lower die seat in a manner of being tightly attached to the trimming male die; the highest points of cutting edges of the waste material cutters are lower than the upper surface of the trimming male die; a material pressing plate is arranged in a female die hole of the trimming female die; a hammering rod is arranged on the material pressing plate; and the upper end of the hammering rod is connected to the die handle through a material pressing spring. The flange trimming die is simple in structure, high in positioning precision and high in product quality; a workpiece and a cut-down flange can be taken out from the flange trimming die conveniently; and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of flange edger.
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 element of cylindrical shape, sphere, taper, box-like, stairstepping, flanged and other complicated shapes by pull and stretch.Its shaping generally is to finish by Drawing Die; its oral area generally all not concordant flange can occur after drawing part is shaped; the processing of need to cutting edge; it generally is to select the flange edger that drawing part is cut edge; there is not location structure on the existing flange edger; workpiece is to be placed directly on the side cut punch; positioning accuracy is poor; and existing flange edger does not have pushing device, and workpiece was easy to be stuck in the die hole after side cut was finished, and is not easy to take out; cut flanged ring was enclosed within on the side cut punch after side cut was finished in addition; be not easy to take out, cause often shutting down cleaning, reduced operating efficiency.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of flange edger, and simple in structure, positioning accuracy is high, good product quality, and workpiece and cut flange conveniently take out from the utility model, have improved operating efficiency.
The technical solution of the utility model is: a kind of flange edger, comprise upper bolster, die shank and die shoe, the die shoe upper surface is provided with the side cut punch, the position that the upper bolster lower surface is corresponding with the side cut punch is provided with trim die, described side cut punch upper surface is provided with positioning boss, the die shoe upper surface is close to the side cut punch and is symmetrically arranged with two scrap cutters, and the cutting edge peak of scrap cutter is lower than the upper surface of side cut punch; Be provided with holding pad in the die hole of trim die, be provided with on the holding pad and make bar, beat the bar upper end and be connected in the die shank by the binder spring.
As preferably, described holding pad is for falling " recessed " font, holding pad and make bar and adopt 45 steel to make, and trim die is connected with upper bolster by screw, and scrap cutter presses fit into the die shoe upper surface.
As preferably, upper bolster, die shank and die shoe adopt the Q235 steel to make, and die shank presses fit in the upper bolster, and side cut punch and trim die adopt carbide alloy to make.
The beneficial effects of the utility model are: be provided with positioning boss on the side cut punch of the present utility model, workpiece to be cut edge can be enclosed within on the positioning boss, and positioning accuracy is high, the good product quality after the side cut.The holding pad that arranges in the die hole can be released workpiece after side cut is finished from die hole, avoid workpiece to be stuck in the die hole.After side cut was finished, upper bolster continued to move down, and trim die working face and scrap cutter bump cut off the flange that is enclosed within on the side cut punch, make things convenient for the taking-up of flange, have improved operating efficiency, and be very convenient and practical.
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 flange edger, comprise upper bolster 7, die shank 5 and die shoe 10, in the present embodiment, as preferably, upper bolster 7, die shank 5 and die shoe 10 adopt the Q235 steel to make good combination property, long service life.Die shank 5 presses fit in the upper bolster 7.Trim die 8 is connected with upper bolster 7 by screw.
Die shoe 10 upper surfaces are provided with side cut punch 1, and upper bolster 7 lower surfaces and side cut punch 1 corresponding position is provided with trim die 8, in the present embodiment, as preferably, side cut punch 1 and trim die 8 adopt carbide alloy to make, and intensity is high, not fragile, long service life.Described side cut punch 1 upper surface is provided with positioning boss 2, and workpiece 3 can be enclosed within on the positioning boss 2.In the present embodiment, positioning boss 2 upper ends are cylindrical, and the lower end is threaded rod, and side cut punch 1 upper surface has the screwed hole that cooperates with threaded rod, and positioning boss 2 is threaded with side cut punch 1.Die shoe 10 upper surfaces are close to side cut punch 1 and are symmetrically arranged with two scrap cutters 9, and as preferably, scrap cutter 9 presses fit into die shoe 10 upper surfaces.The cutting edge peak of scrap cutter 9 is lower than the upper surface of side cut punch 1.In the present embodiment, the cutting edge peak of scrap cutter 9 is thicker than low 5 material of upper surface of side cut punch 1; Be provided with holding pad 4 in the die hole of trim die 8,4 are provided with dozen bar 6 on the holding pad, beat bar 6 upper ends and are connected in the die shank 5 by the binder spring.
In the present embodiment, as preferably, described holding pad 4 is for falling " recessed " font, holding pad 4 and break bar 6 employings 45 steel and make, side cut is finished, upper bolster 7 when moving on the forcing press, holding pad 4 under the effect of binder spring relatively upper bolster 7 move down, workpiece 3 is released, avoided workpiece 3 to be stuck in the die hole.
