Abstract

The invention discloses a punching die for an oil cylinder support beam and relates to the technical field of die manufacturing. The punching die comprises an upper die seat and a lower die seat. The lower end of the upper die seat is provided with a punch fixing plate and a plurality of punches penetrating the punch fixing plate. A discharge plate is disposed below the punch fixing plate. The discharge plate is provided with discharge holes corresponding to the punches. A plurality of discharge screws extending upwards are disposed on the discharge plate, discharge rubber sleeves the discharge screws, and the discharge screws are movably connected with the punch fixing plate. The upper end of the lower die seat is provided with a female die fixing plate. The female die fixing plate and the lower die seat are respectively provided with punching die holes corresponding to the punches and blanking holes corresponding to the punches. Female dies are embedded into the punching die holes. Compared with the prior art, the punching die has the advantages that multiple holes can be punched at one step, the relative positions of the punched holes are accurate, and high work efficiency and low labor intensity are achieved.

Description

Oil cylinder support beam perforating die

Technical field

The present invention relates to technology of die manufacturing field, especially a kind of oil cylinder support beam perforating die.

Background technology

Oil cylinder support beam has three groups of installing holes, and every group includes the hole of four rectangular settings, and because used punch die once can only stamp out a hole, rush after location just need be readjusted in a hole and rushed again next hole, inefficiency, labour intensity is large; Four holes can not be once stamping, and the relative position between hole easily produces deviation, causes to use difficulty is installed, and product percent of pass is low.

Summary of the invention

It is high that technical problem to be solved by this invention is to provide a kind of operating efficiency, the accurate oil cylinder support beam perforating die in position, hole.

In order to address the above problem, the technical solution used in the present invention is: this oil cylinder support beam perforating die, include upper bolster and die shoe, the lower end of described upper bolster is provided with punch fixing plate and is installed on multiple drifts of described punch fixing plate, the below of described punch fixing plate is provided with stripper, described stripper is provided with the dumping pit corresponding with described drift, described stripper is equipped with the multiple unloading bolts that are installed with discharging rubber that protrude upward, and described unloading bolt is flexibly connected with described punch fixing plate; Upper end at described die shoe is provided with die block, and described die block is respectively equipped with punch die hole and the material-dropping hole corresponding with described drift with described die shoe, and described punch die studs with die in hole.

In above-mentioned oil cylinder support beam perforating die technical scheme, technical scheme can also be more specifically: between described punch fixing plate and described upper bolster, be provided with drift backing plate; Between described die block and described die shoe, be provided with die backing plate, described die backing plate is provided with the material-dropping hole corresponding with described drift.

Further, the upper end of described die shoe is provided with at least two guide pillars, and the lower end of described upper bolster is provided with the guide pin bushing being sleeved on described guide pillar, is provided with die shank in the upper end of described upper bolster.

Further, be positioned at described die block and be provided with side location-plate near a side of described guide pillar; The left and right sides at described die block is equipped with bracing frame, and support frame as described above is provided with alignment pin, and described alignment pin lower end is provided with spring.

Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:

1, oil cylinder support beam perforating die of the present invention is provided with punch fixing plate in the lower end of upper bolster and is installed on multiple drifts of punch fixing plate, upper end at die shoe is provided with die block, die block is respectively equipped with punch die hole and the material-dropping hole corresponding with drift with die shoe, and punch die studs with die in hole; Can go out multiple holes, the relative position in multiple holes is accurate at every turn simultaneously, and operating efficiency is high, and labour intensity is low.

2, be positioned at die block and be provided with side location-plate near a side of guide pillar; The left and right sides at die block is equipped with bracing frame, and bracing frame is provided with alignment pin; Registration when punching, product percent of pass is high.

Fig. 2 is the structural representation of the embodiment of the present invention.

Fig. 3 is the cutaway view at the A-A place of Fig. 2.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the invention will be further described:

The required punching of oil cylinder support beam is as shown in Figure 1 divided into three groups, and every group has the hole of four rectangular settings.

A kind of oil cylinder support beam perforating die as shown in Figure 2 and Figure 3, include upper bolster 1 and die shoe 10, the lower end of upper bolster 1 is equipped with punch fixing plate 5 and is installed on the drift 4 of four rectangular settings of punch fixing plate 5, between punch fixing plate 5 and upper bolster 1, drift backing plate 2 is housed; Stripper 8 is equipped with in the below of punch fixing plate 5, and stripper 8 is provided with the dumping pit corresponding with drift 4, and stripper 8 is equipped with four unloading bolts 6 that are installed with discharging rubber 7 that protrude upward, and unloading bolt 6 is flexibly connected with punch fixing plate 5; In the upper end of die shoe 10, die block 9 is housed, between die block 9 and die shoe 10, die backing plate 12 is housed, die block 9 is provided with the punch die hole corresponding with drift 4, studs with die 11 in punch die hole; Die backing plate 12 and die shoe 10 are provided with the material-dropping hole corresponding with drift 4; Two guide pillars 15 are equipped with in the upper end of die shoe 10, and the guide pin bushing 16 being sleeved on guide pillar 15 is equipped with in the lower end of upper bolster 1, in the upper end of upper bolster 1, die shank 3 is installed; Be positioned at die block 9, near guide pillar 15 1 sides, side location-plate 17 be housed; Bracing frame 13 is all equipped with in the left and right sides at die block 9, and alignment pin 14 is housed on bracing frame 13, and spring is equipped with in alignment pin 14 lower ends.

While using oil cylinder support beam perforating die of the present invention to carry out punching, first with upper side and the right flank location of workpiece, go out from right first group of hole several; With upper side and made location, hole, go out successively second group of hole and the 3rd group of hole again; Can go out four holes, the relative position in four holes is accurate at every turn simultaneously, and operating efficiency is high, registration, and product percent of pass is high.
