Abstract

The utility model relates to a drawing die split material press ring structure in die-pin and liner plate modes. The drawing die split material press ring structure in the die-pin and liner plate modes is characterized in that the bottom of one side of a liner plate is fixedly connected with a die-pin extension bar through socket head cap screws, the combined position of the die-pin extension bar and the liner plate is located inside the contour line of a drawing male die, the other side of the liner plate is fixedly connected with a secure hook through a secure hook screw, the liner plate is arranged above a lower bottom plate of the die, the die-pin extension bar penetrates through the lower bottom plate of the die, the bottom of the die-pin extension bar makes contact with a lower air cushion die-pin, a material press ring is perpendicularly arranged on the liner plate and is fixed through fastening bolts, and the whole material press ring is located outside the counter line of the drawing male die. According to the drawing die split material press ring structure in the die-pin and liner plate modes, the die-pin extension bar and the liner plate which are located in the counter line of the drawing male die are fastened and then are assembled with the material press ring to form a split structure.

Description

The drawing die split holding pad structure of pressure pin backing plate form

Technical field

The utility model relates to a kind of drawing die split holding pad structure of pressure pin backing plate form, is applicable to diel, particularly a kind of new construction that adopts the single-action drawing die split holding pad of pressure pin backing plate form.

Background technology

External door panel/left and right rear door outer plate before single cover drawing die punching press simultaneously left and right on end automatic punching line, restriction due to forcing press lower table backing plate, if likely being positioned at, its part pressure pin hole draws in the punch outline line. drawing die adopts normal configuration must change assemble sequence and adopts and first assemble holding pad and assemble the special linkage editor that draws punch after putting in place in this case, and the difficult problems such as punch lifting/screw fastening are drawn in initiation.

Summary of the invention

The purpose of this utility model is to provide a kind of drawing die split holding pad structure of pressure pin backing plate form, its will be positioned at draw the punch outline line with pressure pin extension bar and backing plate form Split type structure with holding pad main body assembling again after fastening.

Technical solutions of the utility model are achieved in that the drawing die split holding pad structure of pressure pin backing plate form, it is characterized in that: backing plate one side bottom is fixedly connected with the pressure pin extension bar by soket head cap screw, within combination place of pressure pin extension bar and backing plate is positioned at and draws the punch outline line, the backing plate opposite side is fixedly connected with auxiliary catch by the auxiliary catch screw, backing plate is positioned over mould lower shoe top, the pressure pin extension bar is through the mould lower shoe, pressure pin extension bar bottom contacts with lower air cushion pressure pin, holding pad is arranged vertically on backing plate and fixes by fastening bolt, holding pad all is positioned at and draws outside the punch outline line.

Good effect of the present utility model is when part, the single draw mould punch outline line outside lacks available pressure pin hole, and a kind of single-action drawing die split holding pad structure that adopts pressure pin backing plate form is provided; Solved whole binder coil structures assemble/disassemble inconvenience in such cases, draw punch fastening/technical barrier of lifting difficult arrangement.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, the drawing die split holding pad structure of pressure pin backing plate form, it is characterized in that: backing plate 5 one side bottoms are fixedly connected with pressure pin extension bar 8 by soket head cap screw 7, within combination place of pressure pin extension bar 8 and backing plate 5 is positioned at and draws punch outline line 10, backing plate 5 opposite sides are fixedly connected with auxiliary catch 3 by auxiliary catch screw 4, backing plate 5 is positioned over mould lower shoe 6 tops, pressure pin extension bar 8 is through mould lower shoe 6, pressure pin extension bar 8 bottoms contact with lower air cushion pressure pin 9, holding pad 1 is arranged vertically on backing plate 5 and fixes by fastening bolt, holding pad 1 all is positioned at and draws outside punch outline line 10.

The die assembly order:

1. pressure pin extension bar 8 is fastening by soket head cap screw 7 with backing plate 5 is the backing plate component;

2. the backing plate component is placed on mould lower shoe 6, as shown in Figure 2;

3. holding pad 1 vertical drop is to backing plate 5, as shown in Figure 3;

4. fastening soket head cap screw 2;

5. by auxiliary catch screw 4, auxiliary catch 3 is arranged on backing plate 5.

Working cycle process: press ram promotes holding pad 1, and the counter-force that drive backing plate 5 pressure pin extension bars 8 overcome air cushion pressure pin 9 under forcing press comes downwards to bottom dead centre; Press ram is up, and it is up that lower air cushion pressure pin 9 promotes pressure pin extension bar 8 drive backing plate 5 holding pads 1, as shown in Figure 4.

Claims

1. the drawing die split holding pad structure of pressure pin backing plate form, it is characterized in that: backing plate one side bottom is fixedly connected with the pressure pin extension bar by soket head cap screw, within combination place of pressure pin extension bar and backing plate is positioned at and draws the punch outline line, the backing plate opposite side is fixedly connected with auxiliary catch by the auxiliary catch screw, backing plate is positioned over mould lower shoe top, the pressure pin extension bar is through the mould lower shoe, pressure pin extension bar bottom contacts with lower air cushion pressure pin, holding pad is arranged vertically on backing plate and fixes by fastening bolt, and holding pad all is positioned at and draws outside the punch outline line.
