Abstract
The utility model discloses the stamping-out cutter of a kind of anti-scraps-bounce, including bit body, this bit body is provided with some curvilinear cut, those curvilinear cut are arranged in protruding on the working edge of bit body, it is characterized in that, described bit body is additionally provided with mechanical type material jacking mechanism, this mechanical type material jacking mechanism includes mounting groove, jigger pin, coil tension spring, described mounting groove is stepped cylinder cell body, described jigger pin is the T-shaped cylinder shank being slidably matched with mounting groove, described coil tension spring is arranged in mounting groove and props up jigger pin, the end face of bit body is stretched out in the front end making jigger pin.By processing mounting groove in stamping-out cutter, jigger pin and coil tension spring are set, form mechanical type material jacking mechanism.During stamping-out, jigger pin is pressed in the mounting groove of bit body by the extruding of plate.During discharging, jigger pin is ejected by coil tension spring, by inhaling the waste material roof fall at cutter head end face, will not produce scraps-bounce.
Description
Technical field
This utility model relates to the structure of blanking punch, particularly to the stamping-out cutter of a kind of anti-scraps-bounce.
Background technology
Scraps-bounce refers to during punch press process, and after material is cut off separation, the material being trapped in die is carried over together along with the rising of punch, and falls in the phenomenon of molding surface.When punch process produces, if it occur that move phenomenon on waste material, on the one hand because operator is careless, personal injury can occur；On the other hand, will also result in the great quality problems such as product rejection, burn failure.
The basic reason causing scraps-bounce is " absorption affinity between waste material and punch > frictional force+waste material gravity " between waste material and die.Particularly thin plate path stamping-out, is trapped in less easily the causing of frictional force between the material in die and die and moves on waste material.In actual production process, concrete reason is complex, mainly has following several.1) during thin plate stamping-out, the shape of blinking scrap is big and thin, tightly adsorbs below drift；2) owing to using thick oil, adhesion is produced because adhesion is relatively big；3) position of stripper, function are improper, uneven with the gap of punch periphery；4) during mould processing or punching production, produce magnetic above punch and produce adsorption phenomena；5) die machining shape has error, and during stamping-out, waste material size d of discharge is less than die hole diameter dimension D.
Therefore it is necessary to take corresponding preventive measure to prevent scraps-bounce.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, it is provided that the stamping-out cutter of a kind of anti-scraps-bounce, the problem solving scraps-bounce.
The technical solution adopted in the utility model is: the stamping-out cutter of a kind of anti-scraps-bounce, including bit body, this bit body is provided with some curvilinear cut, those curvilinear cut are arranged in protruding on the working edge of bit body, it is characterized in that, described bit body is additionally provided with mechanical type material jacking mechanism, this mechanical type material jacking mechanism includes mounting groove, jigger pin, coil tension spring, described mounting groove is stepped cylinder cell body, described jigger pin is the T-shaped cylinder shank being slidably matched with mounting groove, described coil tension spring is arranged in mounting groove and props up jigger pin, the end face of bit body is stretched out in the front end making jigger pin.
Further, the cross section groove in " " shape it is provided with in the middle part of the end face of described bit body.
Further, described jigger pin is positioned at the center of " " shape groove.
Further, it is provided with chamfering between end face and the working edge of described bit body.
Further, described bit body is tetragon cutter head, including the first working edge, the second working edge, the 3rd working edge and the 4th working edge, described first working edge is parallel and symmetrical with described 3rd working edge, described second working edge is parallel and symmetrical with described 4th working edge, and described first working edge, the second working edge, the 3rd working edge and the 4th working edge are provided with curvilinear cut.
This utility model has the advantage that processes hole, rank (mounting groove) in stamping-out cutter, arranges jigger pin and coil tension spring, forms mechanical type material jacking mechanism.During stamping-out, jigger pin is pressed in the mounting groove of bit body by the extruding of plate.During discharging, jigger pin is ejected by coil tension spring, by inhaling the waste material roof fall at cutter head end face, will not produce scraps-bounce.When material is the thinnest, easily it is adsorbed in the end face of bit body due to reasons such as oily adhesion, magnetic, vacuum, bit body is taked corrective measure, the cross section groove in " " shape is set, to reduce the contact area of bit body and waste material, thus reduce the absorption to waste material.
Explanation and detailed description of the invention below in conjunction with the accompanying drawings, the utility model is described in further detail.
