Description
Technical field
The present invention relates to adhesive plaster and make the field, particularly a kind of adhesive plaster punching is with the manufacturing process of cutter.
Background technology
Adhesive plaster is a kind of medical supplies that are widely used, it have fixing, keep a public place clean and multiple function such as warming.But common adhesive plaster is on cotton, to be coated with one deck to have strongly adherent medical glue, has air-locked shortcoming, owing to the air impermeability of adhesive plaster, has seriously influenced its result of use, wound is burst for a long time do not heal.Therefore, present medical proof fabric surface generally all has the small sircle hole of even layout so that the surface of a wound is ventilative and skin perspiration.
The aperture of this small sircle hole that is uniformly distributed with is generally 2mm-5mm, and the center of circle spacing in adjacent two holes is 8mm-15mm.In the prior art, adopt the punch press punching more, once fix and beat several rounds, can only beat 2-3 row such as what have, and the speed of production of this punch press punching is slow, efficient is limited, one minute can be towards about 50-60 time; This hole knockout pitch-row is not easy control, often has the returning charge error, and the uniformity of pitch-row be difficult to guarantee, and noise is bigger when producing, and influences the healthy of employee.
Along with development of NC technology, the punch press punching can be accomplished very accurately, still, is that Digit Control Machine Tool or the cutter that cooperates with it are all very expensive, and production cost increases thereupon.
Summary of the invention
The technical problem that the present invention will solve is: in order to overcome in the prior art, the punch press punching uniformity is bad, the deficiency that the NC cutting tool cost is high; The present invention provides the manufacturing process of a kind of adhesive plaster punching with cutter; Low cost of manufacture, cutter punching good evenness, and long service life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of adhesive plaster punching may further comprise the steps with the manufacturing process of cutter:
(1) process hollow roll and punching unit respectively:
On the hollow roll excircle, offer some through holes that are uniformly distributed with;
The processing punching unit: punching unit comprises interconnected conical nose and trunk portion, and the profile of trunk portion matches with the hollow roll through hole with size, the equal inner hollow of conical nose and trunk portion and be interconnected and be formed for the endoporus of discharge; The top of polishing conical nose makes the top of conical nose form blade; The external diameter of described trunk portion is less than the base diameter of conical nose;
(2) in the hollow roll through hole, inlay punching unit: the trunk portion of punching unit is all inserted in the hollow roll through hole, and fixed with the metal fixative;
(3) inlay punching unit on the hollow roll after, polished in the top of each conical nose, make each blade identical from the distance of the pivot center of hollow roll; Because often thickness is thinner for the adhesive plaster of required punching, and the blade of punching unit is not dark, this step can guarantee that each punching unit can get the hole on adhesive plaster, and can protect the guide roller that cooperates with cutter, prevents that guide roller is local to hurt.
(4) top of polishing conical nose makes blade satisfy the required sharpness of punching.
In the step (1), it is 1.2mm-2.5mm that conical nose is cast as cone height, and cone angle is 80 °-96 ° taper; Endoporus is polished into the circular hole that diameter is 2mm-5mm; The polishing conical top forms blade, and making blade width is 0.01mm-0.02mm.
In the step (1), the polishing endoporus makes inner bore surface roughness less than 0.8, and cross sectional shape is identical with size with the shape of blade with size.
Perhaps endoporus begins to be divided into the upper and lower from inlet, and the cross sectional shape on top is identical with size with the shape of blade with size, and the bore of bottom is greater than the size of blade, and inner bore surface roughness requires can reduce relatively, still makes things convenient for the endoporus discharge.
The waste outlet of described hollow roll inner chamber one end is arranged to the taper outwardly of big opening, and cone angle is 50 °-75 °.
Two ends, described hollow roll outer ring are equipped with the guard circle that is used to protect punching unit, and the polishing guard circle makes the outer ring radius of guard circle equal the height sum of hollow roll outer ring radius and conical nose.
Adhesive plaster of the present invention punches with the operation principle of the made cutter of the manufacturing process of cutter: the corresponding guide roller of placing below cutter, be generally steel rod, and hardness is higher, and steel rod is a drive roll, and cutter is a driven voller, the direction of rotation of guide roller and cutter; The adhesive plaster of required punching is placed between two rollers, and the drive roll rolling drives adhesive plaster and moves, and the cutting edge of conical nose punches to adhesive plaster.Because punching unit is distributed on the hollow roll; A row is uniformly distributed with 15-25 punching unit on the operated by rotary motion hollow roll circumference, and the coaxial 15-20 that is provided with arranges, and the cutter width matches with the adhesive plaster width that needs to produce; Like this; To the disposable punching of adhesive plaster, need not repeated multiple times, do not have the bad problem of the uniformity and produce.Along with the carrying out that produces, waste material slide-down to hollow roll inner chamber is provided with push rod discharge regularly, can not influence the continuity of production, and push rod provides power by cylinder.
The invention has the beneficial effects as follows that adhesive plaster of the present invention punching is with the manufacturing process of cutter, punching unit can batch machining; Reduced manufacturing cost, the cutter punching good evenness of manufacturing can not produce noise; Each blade is identical from the distance of the pivot center of hollow roll, and drilling precision is high; And speed of production is fast, can realize continuous production; Punching unit can repeatedly be polished, long service life; Punching unit is embedded in the hollow roll through hole, and blade is scrapped if any wearing and tearing, only need change punching unit, and maintenance cost is low; The external diameter of trunk portion reduces the through-hole aperture on the hollow roll less than the base diameter of conical nose, makes the hollow roll body that intensity preferably arranged.
