Claims (1)
ダイとポンチとの相対移動に基づくダイ側の切刃
とポンチ側の切刃とのせん断作用によりワークに
せん断加工を施すプレス型において、少なくとも
ダイ側の切刃の縁部近傍に、パツドとの協働によ
りワークのせん断面近傍を印圧するヒル部を突出
形成する一方、ポンチのランド部を挾んで該ラン
ド部先端のせん断用切刃と反対側にばり受容凹部
を形成するとともに、このばり受容凹部とランド
部とのなす稜線部をばり取り用切刃としたことを
特徴とするせん断プレス型。 After pressing the workpiece with the die and pad,
In a press die that performs shear processing on a workpiece by the shearing action between the cutting edge on the die side and the cutting edge on the punch side based on the relative movement between the die and the punch, there is a gap between the pad and the cutting edge at least near the edge of the cutting edge on the die side. By working together, a protruding hill part is formed that presses the vicinity of the sheared surface of the workpiece, while a burr receiving recess is formed on the opposite side of the shearing cutting edge at the tip of the land part by sandwiching the land part of the punch, and this burr receiving recess is formed on the opposite side of the land part tip. A shearing press type characterized by using the ridge line between the recess and the land as a cutting edge for deburring.
