Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
Some embodiments of the present utility model, for those of ordinary skill in the art, are not paying the premise of creative labor
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
In order to be better understood from above-mentioned technical proposal, below in conjunction with Figure of description and specific embodiment to upper
Technical scheme is stated to be described in detail.
As shown in figure 1, the semi-automatic rapid contralateral punching die of a kind of iron pipe described in the present embodiment, including it is symmetrical
Drift 1 be symmetrically distributed in iron pipe both sides；Device die center 3 in iron pipe, die center 3 is provided with symmetrical holes, for protecting punching
The iron pipe inwall of hole site, the circumferential shape distortion of iron pipe hole is prevented when drift punching enters in pipe, punching burr is reduced；Punch die
Core rod 3 is fixed in fuse chain adapter 4, and lower punch fuse chain adapter 4 and drift same time shift in the horizontal direction are driven in stepper motor
Move next punching station；Ejector beam 2 is advance on rear side of punching station, the moment after drift 1 rushes waste material and exits iron pipe,
It is quick to be retreated to next time on rear side of next punching station from eject after station by waste material from iron pipe, then in stepper motor drive.
Wherein, drift 1 uses T10A materials, and through Overheating Treatment, hardness is controlled in 55-60HRC, blade shape and iron pipe phase
Identical, blanking pressure distribution is steady, is punched and designs in Bilateral Symmetry, the side force that can be cancelled out each other when being punched, thus, the drift longevity
Life is longer, and average every drift can go out ten thousand holes of 3.5-3.7；Drift 1 is fixed on hydraulic cylinder, and hydraulic pressure 1.2~
1.5MP, by programme-control hydraulic selector, hydraulic cylinder controls the impulse stroke of drift 1, it is ensured that penetraction depth during punching, protects
Card safety in production;0.75~1s of cycle is punched per device to hole, production efficiency is high；Hydraulic cylinder is driven to each punching by stepper motor
Station, translational speed 0.5~0.8m/s accurate positionings.
Wherein, die center 3, are made by H13 mould steel, and external diameter reduces 0.3~0.5mm than iron pipe internal diameter, there is symmetrical individually
The hole of two 17, axially bore 18 through hole, tail end car stud bar is to fix core rod subchain adapter 4, through Overheating Treatment, firmly
Degree control is in 52-54HRC, and with high-wearing feature, single die center 3 slidably coordinates drift 1 to go out 20~250,000 device to hole；Punch die
The tight note of core 3 iron pipe inwall and makees horizontal direction and the synchronous slide of drift 1, and the inwall for protecting iron pipe punch area prevents punching
Distortion, reduces punching burr；Die center 3 sets symmetrical holes in iron pipe punching position, size it is more unilateral than drift it is big by 0.5~
0.7mm, prevents from interferenceing with drift 1.
Wherein, the internal diameter 18 of core rod subchain adapter 4, the ejector beam 2 of placement a diameter of 17.
Wherein, ejector beam 2 is by one section of long 50~80mm, diameter 16mm 42CrMo steel wire rods and 16 steel-pipe welding
Make, 42CrMo steel are used for front end and eject waste material, and heat treatment hardness HRC48-55 inside has high-wearing feature.
It is described above, only it is preferred embodiment of the present utility model, not makees any formal to the utility model
Limitation, although the utility model is disclosed above with preferred embodiment, but is not limited to the utility model, any ripe
