Summary:To provide a metal mold management device which can determine a state of a metal mold tip with high accuracy.SOLUTION: A cumulative abrasion amount calculation part 205 calculates abrasion loss of a punch and a die tip when a metal mold set processes a sheet metal once by a formula with use of a coefficient according to a real number of a clearance value between a dimension of a punch tip and a dimension of the die tip when a punching machine 1 processes the sheet metal with a metal mold set of punch and die. The cumulative abrasion amount calculation part 205 accumulates abrasive loss at each time when the metal mold set processes the sheet metal multiple times, thereby calculating cumulative abrasive loss of the punch and the die tip. A metal mold management information part 208 causes a metal mold management information storage part 209 to store a metal mold identification code given to each punch and each die and the cumulative abrasive loss calculated by the cumulative abrasion amount calculation part 205, and manages state of each punch and each die tip.SELECTED DRAWING: Figure 1 【課題】金型の刃先の状態を高精度に判定することができる金型管理装置を提供する。【解決手段】累積摩耗量計算部205は、パンチング加工機1がパンチとダイとの金型の組で板金を加工したときの、パンチの刃先の寸法とダイの刃先の寸法とのクリアランス値の実数またはクリアランス値に応じた係数を用いた計算式によって、金型の組が板金を1回加工したときのパンチ及びダイの刃先の摩耗量を計算する。累積摩耗量計算部205は、金型の組が板金を複数回加工したときの各回の摩耗量を累積することによって、パンチ及びダイの刃先の累積摩耗量を計算する。金型管理情報管理部208は、金型管理情報記憶部209に、各パンチ及び各ダイに付与されている金型識別符号と、累積摩耗量計算部205によって計算された累積摩耗量とを対応させた金型管理情報を記憶させて、各パンチ及び各ダイの刃先の状態を管理する。【選択図】図1
