Abstract

The utility model belongs to punching equipment which is the improvement of a die blanking device for rubber plugs. In the utility model, tail holes 11 are arranged at the tail ends of punching needles 10. More than one steel needle 12 penetrate through the tail holes of the punching needles in the same line in turn. Moreover, the steel needle is placed in an installing cavity 9 which is arranged on a positioning plate. The punching needles are in the movable state. Openings of array holes 8 on a charging plate 4 are provided with chamfering. Blanking holes 14 are arranged in the array holes. The utility model has the advantages of simple production, simple maintenance, quick and labor-saving blanking, no accumulate and extrusion to material granules, high production efficiency and high production quality. The adaptability of the punching needle and the array holes is good.

Description

The die-cut die device of rubber stopper

The utility model belongs to die cutting device, is the improvement of the die-cut die device of a kind of rubber stopper.

The existing die-cut die device of rubber stopper has two places mainly not enough: the one, be fixed on the location-plate towards pin, and both increased the manufacturing maintenance difficulty, the feasible again aligned apertures bad adaptability on pin and guide plate.The 2nd, feeding intake is difficult to the location and the material-dropping hole aperture is identical up and down, has increased die-cut time and die-cut strength, and has caused material grain accumulation crimp.

The utility model is to provide a kind of manufacturing easy to maintenance, good towards pin and aligned apertures adaptability for the deficiency that overcomes above-mentioned technology, again can the blanking convenient power-saving, do not influence product distortion rubber stopper blanking units.

The utility model is finished by following technical solution.

The die-cut die device of this rubber stopper comprises location-plate, the guide plate that is fixed with connecting plate and the plate that feeds intake, corresponding positioning hole matches the three on guide positioning pin, the guide plate on the location-plate and the plate that feeds intake by being fixed on, the spring compression discharging device is arranged between location-plate and the guide plate, have the consistent aligned apertures of hole count on location-plate, guide plate and the plate that feeds intake, be provided with in the aligned apertures towards pin, have uropore towards the backshank end, draw point more than one passes the uropore of same column towards pin successively, and rests in the installation cavity of offering on the location-plate.There is chamfering in aligned apertures aperture on the plate that feeds intake of this device, and the hole lower diameter increases and forms material-dropping hole.

Fig. 1 is a front view of the present utility model;

Fig. 2 is an A-A view of the present utility model.

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

See Fig. 1 and Fig. 2.The utility model comprises that (this example is 170mm * 170mm) for location-plate 2, the guide plate 3 that is fixed with connecting plate 1 and the plate 4 that feeds intake, corresponding positioning hole 6 (see figure 2)s match the three on guide positioning pin 5, the guide plate on the location-plate 2 and the plate that feeds intake by being fixed on, there is bolt spring to compress discharging device 7 between location-plate and the guide plate, have the consistent aligned apertures of hole count 8 on location-plate, guide plate and the plate that feeds intake, this example is 8 * 8 holes, and location-plate is provided with the installation cavity 9 about degree of depth 5mm; What be provided with 64 Φ 11.2mm in the aligned apertures dashes pin 10, is slightly less than aligned apertures towards the pin diameter, all has the radially uropore 11 of Φ 1.4mm towards the backshank end.8 diameters than the smaller draw point of uropore 12 every pass 8 uropores successively, and rest in the installation cavity, the backshank end that dashes that installs peaks at connecting plate, can fine motion in the hole, increased adaptability with the lower plate aligned apertures.45 °-60 ° chamfering 13 is all established in feed intake aligned apertures aperture on the plate, and this example is 60 °, has made things convenient for the location that feeds intake.Material-dropping hole 14 diameters are bigger than aligned apertures, and hole depth can be controlled in about half of the plate thickness that feeds intake, both made blanking quick, alleviated installation weight again.

The utility model manufacturing maintenance is all fairly simple, has reduced cost, and is good towards the adaptability of pin and aligned apertures, the blanking convenient power-saving, and the material grain does not have the accumulation extruding, has improved production efficiency and product quality.
