Abstract
The utility model relates to a novel blanking structure used for preventing waste materials of a high-speed stamping die from floating upward and cooling the stamping die. The novel blanking structure comprises an upper die base, a fixing plate and a punch, wherein the fixing plate is fixedly arranged on the upper die base through a cushion plate, and the punch is fixed on the fixing plate in an inserting way; the novel blanking structure is characterized in that an axial through hole is arranged on the punch; an air inlet connected with a high pressure air source is arranged on the side surface of the upper die base; and the upper die base and the cushion plate are provided with an air passing channel which can communicate the axial through hole and the air inlet. The utility model adopts an air inlet structure formed by the axial through hole, the air inlet and the air passing channel, high pressure air flow flowing through the air inlet structure can form thrust on the stamped waste materials during the punching, so that the waste materials can be tightly adhered to the blanking stop position, in addition, the heat generated by the friction between the front end of the punch and a material belt can be brought away by the high pressure air flow, the cooling effect is simultaneously played, and the service life of the punch is prolonged.
Description
Technical field
The utility model relates to the novel stamping-out structure that is used for anti-waste material come-up of high-speed stamping die and cooling.
Background technology
In strip stamping-out process, the problem of waste material come-up appears through regular meeting, and after promptly the waste material stamping-out under got into concave die cavity, owing to receiving moment vacuum or the influence in gap, waste material was deviate from matrix cavity, drops on the mold work surface.This problems affect the quality and the die life of product.The structure of anti-waste material come-up commonly used at present has two kinds: add ejector beam 10 structures on (1) drift 4, referring to Fig. 2; (2) add breach 12 structures on the die 11, referring to Fig. 3.Above-mentionedly add the drift that the liftout structure is applicable to heavy in section or middle section,,, limited the use of this structure because push rod structure takies certain space for the less drift of sectional dimension.Add the breach structure on the above-mentioned die, small burr can occur in indentation, there, under long-time high speed blanking, burr becomes greatly gradually, directly has influence on product quality.In addition, the friction of punch and strip can produce heat when mold high speed is worked, and long-time friction can make the drift local temperature raise, and has influenced the service life of drift.
Summary of the invention
The utility model provides a kind of little drift processing that is suitable for for solving the technical problem that exists in the known technology, guarantees the novel stamping-out structure that is used for anti-waste material come-up of high-speed stamping die and cooling of punching quality.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of novel stamping-out structure that is used for anti-waste material come-up of high-speed stamping die and cooling; Comprise that upper bolster, the fixed head and the plug-in mounting that are packed in upper bolster through backing plate are fixed on the drift on the fixed head; It is characterized in that: said drift is provided with axially extending bore; The side of said upper bolster is provided with the air inlet that is connected with high-pressure air source, and said upper bolster and backing plate are provided with the gas passage excessively that axially extending bore and air inlet are communicated with.
The technical scheme that the utility model can also be taked is:
The said gas passage of crossing that is located on the backing plate comprises that the horizontal groove that is arranged at the backing plate upper surface reaches the through hole perpendicular to horizontal groove, and the axially extending bore on said through hole and the drift aligns.
Advantage and the good effect that the utlity model has are:
Adopt the above-mentioned air intake structure that constitutes by axially extending bore, air inlet and mistake gas passage; When punching, the high pressure draught that flows into through air intake structure forms thrust to the waste material that sweeps away, and makes waste material be close to the position that stamping-out stops; In addition; High pressure draught is taken away punch and the fricative heat of strip, plays the effect of cooling simultaneously, has prolonged the service life of drift.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sketch map that adds the ejector beam structure in the prior art on the drift;
Fig. 3 is the sketch map that adds the breach structure in the prior art on the die.
Among the figure: 1, upper bolster; 2, backing plate; 3, fixed head; 4, drift; 5, axially extending bore; 6, air inlet; 7, horizontal groove; 8, through hole; 9, ejector beam; 10, die; 11, breach.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1; A kind of novel stamping-out structure that is used for anti-waste material come-up of high-speed stamping die and cooling; Comprise that upper bolster 1, the fixed head 3 and the plug-in mounting that are packed in upper bolster through backing plate 2 are fixed on the drift 4 on the fixed head; Said drift is provided with axially extending bore 5, and the side of said upper bolster is provided with the air inlet 6 that is connected with high-pressure air source, and said upper bolster and backing plate are provided with the gas passage excessively that axially extending bore and air inlet are communicated with.Be the use of the small-sized drift that is applicable to different size, above-mentioned being located at crosses that the gas passage can further comprise the horizontal groove 7 that is arranged at the backing plate upper surface and perpendicular to the through hole 8 of horizontal groove, the axially extending bore on said through hole and the drift aligns on the backing plate.
To sum up, the utility model adopts the above-mentioned air intake structure that is made up of axially extending bore, air inlet and mistake gas passage, when punching; The high pressure draught that flows into through air intake structure forms thrust to the waste material that sweeps away; Make waste material be close to the position that stamping-out stops, in addition, high pressure draught is taken away punch and the fricative heat of strip; Play the effect of cooling simultaneously, prolonged the service life of drift.
Claims (2)
