Abstract

Strižnica bočnej strihacej jednotky je použitelná najma ako súčasť kombinovaného postupového tvárniaceho nástroja. Pozostáva z telesa, v ktorom je pomocou prvých skrutiek prichytená střižná vložka a pomocou druhých skrutiek klínová rozperná vložka. Střižná vložka je zo vstupnej strany opatřená střižným otvorom a je ohraničená zhora hornou plochou, rovnoběžnou so základnou rovinou strižnice, zo vstupnej strany čelnou plochou, zo strany klinovej rozpernej vložky přítlačnou plochou a zdola základnou plochou, ktorou je uložená na dosadacej ploché telesa strižnice. Riešeným problémom je umožnenie viacnásobného ostrenia čelnej plochy strižnej vložky bez zložitej manipulácie, čo sa dosahuje tým, že základná plocha strižnej vložky a dosadacia plocha telesa strižnice sú voči základnej rovině strižnice skloněné pod takým uhlom, pod akým je voči uvedenej základnej rovině skloněný střižný otvor.The shearing die of the side shearing unit is usable especially as a part of a combined progressive forming tool. It consists of a body in which the shearing insert is attached by means of the first screws and the wedge spacer insert by means of the second screws. The shearing insert is provided with a shearing opening on the input side and is bounded from above by an upper surface, parallel to the base plane of the shearing die, from the input side by an end surface, from the side of the wedge spacer insert by a pressure surface and from below by a base surface, by which it is placed on the supporting surface of the shearing die body. The problem solved is to enable multiple sharpening of the front surface of the shearing insert without complicated manipulation, which is achieved by the fact that the base surface of the shearing insert and the supporting surface of the shearing die body are inclined to the base plane of the shearing die at such an angle as the shearing opening is inclined to the said base plane.

Description

Vynález sa týká strižnice bočnej strihacej jednotky, vhodnej najmá pre kombinovaný postupový tvárniaei nástroj, pozostávajúcej z telesa, v ktorom je pomocou prvých skrutiek prichytená střižná vložka a pomocou druhých skrutiek klínová rozperuá vložka, kde střižná vložka je zboku opatřená střižným otvorom a je ohraničená zhora hornou plochou, rovnoběžnou so základnou rovinou strižnice, zo vstupnej strany čelnou plochou, zo strany klinovej rozpernej vložky přítlačnou plochou a zdola základnou plochou, ktorou je střižná vložka uložená na dosadacej ploché telesa strižnice.BACKGROUND OF THE INVENTION The present invention relates to a die cutter of a side shearing unit suitable, in particular, for a combined progressive die consisting of a body in which a shearing insert is fastened by means of first screws and a wedge spacing insert by means of second screws, wherein the shearing insert is provided with a shearing opening from the side and bounded from above by a top a face parallel to the base plane of the cutting die, from the inlet face through the face, from the wedge spacing insert by the pressing face and from below the base face by which the cutting insert is mounted on the cutting face of the cutting die.

Podfa známého stavu techniky bývá základová plocha strižnej vložky vodorovná, t. j. rovnoběžná s jej hornou plochou, resp. so základnou plochou celého nástroja. Takéto riešenie je vyhovujúce len u nástrojov, kde sa střih vykonává tiež len vo vodorovnej rovině. V případe, že os strižníka, resp. střižného otvoru leží v nakloněněj rovině, je toto riešenie nevyhovujúce z hfadiska postupného ostrenia čelnej plochy strižnej vložky, pretože po odbrúsení čelnej plochy a následnom dotlačení strižnej vložky dochádza k vyoseniu strižníka voči střižnému otvoru.According to the known state of the art, the base surface of the shearing insert is horizontal, i.e. parallel to its upper surface, respectively. with the base of the entire tool. Such a solution is only suitable for tools where the cut is also performed only in a horizontal plane. If the axis of the cutter, respectively. the cutting hole lies in an inclined plane, this solution is inconvenient for the gradual sharpening of the face of the cutting insert, since after cutting off the face and subsequent pressing of the cutting insert, the cutting die is offset against the cutting hole.

Uvedenú nevýhodu odstraňuje strižnica bočnej strihacej jednotky podfa vynálezu, ktorého podstata spočívá v tom, že základná plocha strižnej vložky a dosadacia plocha telesa strižnice sú voči základnej rovině strižnice skloněné pod takým uhlom, pod akým je voči uvedenej základnej rovině skloněný střižný otvor. Výhodou strižnice podfa vynálezu je, že po otupení čelnej plochy strižnej vložky so střižným otvorom jednoduchou manipuláciou a jednoduchými tecnickými prostriedkami sa opakované vysunie střižná vložka zo svojej východiskovej polohy o potrebnú hodnotu pre ostrenie bez toho, že by došlo ku zmene polohy osiThis disadvantage is eliminated by the cutting shear of the side shearing unit according to the invention, the principle of which is that the base surface of the shearing insert and the bearing surface of the shearing body are inclined at an angle with respect to the base plane of the shearing opening. An advantage of the cutting die according to the invention is that, after blunting the face of the cutting insert with a shear opening by simple handling and simple technical means, the cutting insert is repeatedly moved out of its initial position by the necessary value for sharpening without changing the position of the axis
