Abstract

The utility model discloses a pre-pressing forming die, which comprises an upper die base, an upper base plate, an upper dead plate, a check plate, a discharging plate, a lower die plate, a lower base plate, a lower die base, male dies, swaging blocks, swaging rods, swaging springs, female dies and lower stripper plates, wherein the upper die base, the upper base plate, the upper dead plate and the check plate are overlapped in sequence and are fixedly connected together, and the discharging plate is arranged below the check plate through discharging rods. The male dies are fixedly arranged on the upper dead plate; the swaging blocks are movably sheathed into the discharging plate and are movably sheathed with the lower parts of the male dies; the female dies are arranged in the lower die plate and are opposite to the male dies; the lower die plate, the lower base plate and the lower die base are overlapped in sequence and are fixedly connected together; and the lower stripper plates are respectively sheathed into the female dies. According to the pre-pressing forming die disclosed by the utility model, the lower parts of the male dies are respectively and movably sheathed with the swaging blocks; when drawing is performed, the bottom faces of the swaging blocks exceed the bottom face of the discharging plate, and the swaging blocks can be firstly pressed on the upper surface of a metal sheet, thereby, the edge of a drawing part is better prevented from wrinkling in the drawing process.

Description

The pre-compacted mould

Technical field

The utility model relates to a kind of diel, particularly relates to a kind of pre-compacted mould.

Background technology

Pull and stretch is to utilize mould plate blank or semi-finished product blank pull and stretch to be become a kind of cold punching technology of open hollow part.In drawing process,, wrinkling easily at the drawing part edge owing to metal material is assembled to die.So before pull and stretch, holding pad need be set be pressed on the sheet metal, prevent that pull and stretch is wrinkling.The holding pad of commonly using is the holding pad of a monoblock, and to having the cupping tool of a plurality of punch, wrinkle resistant effect is bad.

The utility model content

The purpose of the utility model is to provide a kind of pre-compacted mould that effectively prevents to draw wrinkle.

For realizing above-mentioned purpose, the technical solution of the utility model is:

The utility model is a kind of pre-compacted mould, and it comprises upper bolster, upper padding plate, upper mounted plate, ends high plate, stripper, lower bolster, lower bolster, die shoe, punch, binder block, compressing rod, binder spring, die, lower stripper; Described upper bolster, upper padding plate, upper mounted plate, to end high plate superimposed successively and be fixed together, and stripper is installed in the below of ending high plate through discharge arm; The upper end of described punch is fixed on the upper mounted plate; Its lower end is located in the stripper, and described binder block activity is nested with in stripper and is actively socketed on the bottom of punch, and the bottom surface of binder block exceeds the stripper bottom surface; The top of binder block is connected with the lower end of compressing rod; Compressing rod is arranged in upper mounted plate and ends in the high plate, and the lower end of the upper end of compressing rod and binder spring leans, and the upper end of binder spring leans the plug in being fixed in upper bolster; Described die is installed in the lower bolster and is relative with punch, and lower bolster, lower bolster, die shoe are superimposed successively and be fixed together; Described lower stripper is nested with in die.

Described punch, binder block, die have many groups; The upper end of described a plurality of punch is separately fixed on the upper mounted plate, and its lower end is located in the stripper; The activity of described polylith binder block is nested with the bottom that is actively socketed on a plurality of punch in stripper and respectively, and a plurality of dies are relative with a plurality of punch respectively.

After adopting such scheme; The utility model is difference pivot bush unit binder block in the bottom of a plurality of punch, during pull and stretch, because the bottom surface of binder block exceeds the stripper bottom surface; Binder block can be pressed in the upper surface of sheet metal earlier, thereby prevents the wrinkling of drawing part edge in the drawing process preferably.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Description of drawings

Fig. 1 is the structure chart of the utility model.

The specific embodiment

As shown in Figure 1; The utility model is a kind of pre-compacted mould, and it comprises upper bolster 1, upper padding plate 2, upper mounted plate 3, end high plate 4, stripper 5, lower bolster 6, lower bolster 7, die shoe 8, punch 9, binder block 10, compressing rod 20, binder spring 30, die 40, lower stripper 50.

Described upper bolster 1, upper padding plate 2, upper mounted plate 3, to end high plate 4 superimposed successively and be fixed together, and stripper 5 is installed in the below of ending high plate 4 through discharge arm.

Described punch 9, binder block 10, die 40 have many groups.The upper end of described a plurality of punch 9 is separately fixed on the upper mounted plate 3, and its lower end is located in the stripper 5; 10 activities of polylith binder block are nested with in stripper 5 and are actively socketed on the bottom of a plurality of punch 9 respectively; The bottom surface of each binder block 10 exceeds stripper 5 bottom surfaces; The top of binder block 10 is connected with the lower end of compressing rod 20; Compressing rod 20 is arranged in upper mounted plate 3 and ends in the high plate 4, and the lower end of the upper end of compressing rod 20 and binder spring 30 leans, and the upper end of binder spring 30 leans the plug 60 in being fixed in upper bolster 1; Binder spring 30 gives binder block 10 1 downward elastic pressures through compressing rod 20.

Described a plurality of die 40 be installed in the lower bolster 6 and a plurality of dies 40 relative with a plurality of punch 9 respectively.Lower bolster 6, lower bolster 7, die shoe 8 is superimposed successively and be fixed together; Described lower stripper 50 is nested with in die 40.

The operation principle of the utility model

During pull and stretch, because the bottom surface of binder block 10 exceeds stripper 5 bottom surfaces, binder block 10 can be pressed in the upper surface of sheet metal 100 earlier, thereby prevents the wrinkling of drawing part 101 edges in the drawing process preferably.

The emphasis of the utility model just is: a plurality of binder blocks are set.

The above; Be merely the utility model preferred embodiment; Can have needs and decide in the position of the quantity of binder block; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
