Abstract
The utility model relates to a punching die for microporous anti-tripping waste, comprising a terrace die and a concave die. The concave die is provided with a first through hole for punching the micropore. A concave die gasket is arranged below the concave die and the concave die gasket is provided with a second through hole corresponding to the first one in position; the concave die is provided with an inclined hole. An air inlet of the inclined hole is adjacent to the concave die while an air outlet of the inclined hole is located on the side wall of the second through hole and far from the terrace die. The concave die gasket is provided with an air inlet channel, the air inlet end of the air inlet channel is communicated with an air nozzle while the air outlet end thereof is connected with the air inlet end of the inclined hole. The utility model has a simple structure, and is simple to operate and effectively prevents waste from tripping, and is suitable for the field of punching dies.
Description
Technical field
The utility model relates to a kind of diel.
Background technology
Existing diel mainly comprises punch and die, and there is the die backing plate die below.For the diel towards aperture, the drift of punch relevant position is an elongate, and die is provided with and the corresponding through hole of punch shape, and the die backing plate is provided with the through hole corresponding with this through hole.Waste material after the punching press is discharged, and mainly leans on the gravity of material self, from the discharge of dropping of the through hole of die, die backing plate.
For existing diel towards aperture, have following shortcoming: 1. because waste material is in light weight, and the drift uphill process can get on the waste material band, product was weighed wounded when the existence of waste material caused next punching press; 2. in order to overcome above-mentioned shortcoming, generally need the operator to detect by an unaided eye, when finding that drift is stained with waste material, the artificial removal is wasted time and energy; 3. the aperture of aperture is more little, and waste material gets lodged in the die more easily, and the waste material transition is overstock sometimes even can be damaged die.
The utility model content
To the technical problem that exists in the prior art, the purpose of the utility model is: provide a kind of simple in structure, the aperture of effectively removing the waste material of aperture is prevented the diel of jump-scrap.
In order to achieve the above object, the utility model adopts following technical scheme:
The diel of the anti-jump-scrap of aperture comprises punch and die, and die is provided with first through hole of using towards aperture; The die below has die backing plate, die backing plate to be provided with and the first lead to the hole site corresponding second through hole; Be provided with inclined hole in the die backing plate, the inlet end of inclined hole is near die, and the outlet side of inclined hole is positioned at the sidewall of second through hole and away from die; The die backing plate is provided with inlet channel, and the inlet end of inlet channel is communicated with valve, the inlet end of the termination inclined hole of giving vent to anger of inlet channel.
After adopting this structure, the gas circuit of valve, inlet channel, inclined hole and second through hole is communicated with because the inlet end of inclined hole up, the outlet side of inclined hole below; After the valve work, the air-flow of inclined hole ejection flows downward in second through hole, so in second through hole, the downward suction of whole generation; Waste material down is with, is effectively avoided waste material to stop up die or be bonded on the drift, simple in structure, easily and effectively; Effectively guarantee the stamping products quality, effectively protect mould, time saving and energy saving.
Inlet channel is on the surface of die backing plate near die.This structure is convenient to milling machine processing die backing plate.The sidewall of die backing plate is provided with the air nozzle hole that joins with valve, the air inlet termination air nozzle hole of inlet channel.This structure is convenient to add valve from side direction, and is simple in structure, easy to operate.The distance of the outlet side of inlet channel and second through hole is 2 millimeters.The width of inlet channel is 4 millimeters, and the degree of depth is 2 millimeters.The restriction of this size can obtain best air blowing effect.
Inclined hole is a straight hole.The axis of inclined hole and the angle of horizontal plane are more than or equal to 60 degree and less than 90 degree.Straight hole is easy to process, especially when inclined hole enough tilts, can obtain best downward suction.The diameter of inclined hole is 1 millimeter.The aperture is more little, and air-flow is concentrated more, and suction is good more, is easy to processing but will satisfy.
Second through hole of diel and inclined hole have many groups, and each group all connects the inlet channel of a connection.This structure, promptly a valve connects an inlet channel, and inlet channel is communicated with respectively with each inclined hole, and inclined hole is communicated with its corresponding second through hole again.Open a valve, can blow to each second through hole simultaneously, to the anti-jump-scrap of a plurality of apertures, simple and compact for structure, easy to process simultaneously.
Generally speaking, the utlity model has following advantage: simple in structure, easy to operate, effectively prevent jump-scrap.

The specific embodiment
To combine the accompanying drawing and the specific embodiment to come the utility model is done further detailed explanation below.
Fig. 1 is to the diel for the anti-jump-scrap of aperture shown in Figure 4.This diel from top to bottom is followed successively by: upper bolster, and fixing backing plate, fixed head takes off the backing strap plate, stripper plate, concave template and the die that is positioned at it, die backing plate, die shoe and mould pin composition.The drift of the punch of press forming small hole is an elongated shape, and the place that die is corresponding with the drift position is provided with first through hole, and the corresponding place of die backing plate of die below is provided with second through hole.
Be provided with the inclined hole that communicates with second through hole in the die backing plate, inclined hole is a straight hole, and the angle of its axis and horizontal plane is 60 degree.The upper surface of die backing plate has inlet channel, and inlet channel is wide 4 millimeters with milling machine processing, dark 2 millimeters groove.The sidewall of die backing plate is provided with the air nozzle hole that joins with valve.The air inlet termination air nozzle hole of inlet channel, the inlet end of the termination inclined hole of giving vent to anger of inlet channel, the outlet side of inclined hole is positioned on the sidewall of second through hole; The inlet end of inclined hole is above the outlet side.
Shown in Figure 4, second through hole and inclined hole have many groups, and each inclined hole communicates with the inlet channel of a connection respectively.During valve work, air-flow gets into each inclined hole along inlet channel, sprays from top to bottom in corresponding second through hole, and waste material is taken out of from top to bottom, avoids waste material obstruction or waste material to be bonded on the drift.
