Abstract
The utility model discloses a two-hole symmetrically punching die for tube stocks and relates to a stamping die. The die comprises an upper die base, a lower die base and an upper male die, wherein guide posts are arranged between the upper die base and the lower die base, the upper male die is arranged on the lower surface of the upper die base, the two guide posts are symmetrically arranged on two sides of the upper male die left and right, a lower male die is arranged at a position corresponding to the upper male die on the lower die base, a female slide block is arranged between the upper male die and the lower male die, two ends of the female slide block are sleeved on the two guide posts respectively and connected with the lower die base through reset rubber pads, a through hole for fixing tube stocks is arranged on the side wall of the female slide block, and female die holes communicated with the through hole are arranged on the upper and lower surfaces of the female die slide block respectively. The die can mold two holes which are symmetrical at 180 degrees on the side wall of a tube stock once, resetting is not needed, the safety is good, and the productivity and product accuracy are improved.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of tubing diplopore to punch die.
Background technology
Usually need to be at side-wall hole or the groove of metal pipe material in machining is produced, if adopt brill or mill processing, its workload is large, inefficiency and dangerous.Adopt the processing of perforating die stamping-out, can boost productivity, and constant product quality, safe, but there are some defectives in existing perforating die, existing perforating die only has a punch, a punching press can only be rushed a hole, if metal pipe material need to be on sidewall 180 degree symmetrical rush two holes, use existing perforating die just to need first then tubing Rotate 180 degree to be rushed another hole again in hole of a side blow, very inconvenient like this, productivity ratio is low, poor stability, and if after the rotation the inaccurate precision that usually causes workpiece in location low even scrap.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of tubing diplopore to punch die, can the one-shot forming tube sidewall on two symmetrical holes of 180 degree, do not need resetting, security is good, has improved the precision of productivity ratio and product.
The technical solution of the utility model is: a kind of tubing diplopore is to punch die; comprise upper bolster; die shoe and upper male mould; be provided with guide pillar between upper bolster and the die shoe; upper male mould is arranged at the upper bolster lower surface; guide pillar is two; be symmetrical set in the upper male mould both sides; position corresponding with upper male mould on the die shoe is provided with lower punch; be provided with the die slide block between upper male mould and the lower punch; die slide block two ends are socketed on respectively on two guide pillars; and be connected with die shoe by the rubber blanket that resets, the die slider side wall has for the fixing through hole of tubing, and die slide block upper and lower surface has the die hole that is communicated with through hole.
As preferably, upper bolster and die shoe all adopt the Q235 steel to make, and guide pillar press-fits on die shoe, and guide pillar adopts 20 steel to make, and the described rubber blanket that resets is two, is socketed on respectively on two guide pillars.
As preferably, described upper male mould and lower punch all adopt the GCr15 steel to make, and are stairstepping, and upper male mould is connected with upper bolster by upper mounted plate, and lower punch is connected with die shoe by bottom plate.
As preferably, between upper male mould and the upper bolster, be respectively arranged with backing plate between lower punch and the die shoe.
The beneficial effects of the utility model are: upper male mould of the present utility model and lower punch position are corresponding; during punching press tubing packed in the through hole of die slide block; in punching stroke; upper male mould and lower punch can be finished the moulding in two symmetrical holes of tubing sidewall 180 degree simultaneously; need not be with the workpiece resetting, security is good, saves operation; boost productivity, and improved the precision of product.Guide pillar and the rubber blanket that resets can guarantee the positional precision of die slide block, avoid the die slide block to depart from its operating position under the effect of upper male mould and lower punch.
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 tubing diplopore is to punch die, comprise upper bolster 6, die shoe 1 and upper male mould 5, in the present embodiment, as preferably, upper bolster 6 and die shoe 1 all adopt the Q235 steel to make, good combination property, long service life.Be provided with guide pillar 3 between upper bolster 6 and the die shoe 1, in the present embodiment, as preferably, guide pillar 3 press-fits on die shoe 1, and guide pillar 3 adopts 20 steel to make.Upper male mould 5 is arranged at upper bolster 6 lower surfaces; guide pillar 3 is two; be symmetrical set in upper male mould 5 both sides, position corresponding with upper male mould 5 on the die shoe 1 is provided with lower punch 10, is provided with die slide block 4 between upper male mould 5 and the lower punch 10; die slide block 4 two ends are socketed on respectively on two guide pillars 3; and be connected with die shoe 1 by the rubber blanket 2 that resets, in the present embodiment, as preferably; the described rubber blanket 2 that resets is two, is socketed on respectively on two guide pillars 3.Die slide block 4 sidewalls have for the fixing through hole of tubing 9, and die slide block 4 upper and lower surfaces have the die hole that is communicated with through hole.
In the present embodiment, as preferably, described upper male mould 5 and lower punch 10 all adopt the GCr15 steel to make, and intensity is high, not frangibility.Upper male mould 5 and lower punch 10 are stairstepping, good rigidity.Upper male mould 5 is connected with upper bolster 6 by upper mounted plate 8, and lower punch 10 is connected with die shoe 1 by bottom plate 11.Between upper male mould 5 and the upper bolster 6, be respectively arranged with backing plate 7 between lower punch 10 and the die shoe 1.Backing plate 7 can reduce the impact to upper bolster 6 and die shoe 1, prolongs service life of the present utility model.
