DIE AND DIE STOCKER

PROBLEM TO BE SOLVED: To provide a die and a die stocker which allow easy charging of a charging type cell in the die comprising a folding angle detection sensor, radio communication means and the charging type cell.SOLUTION: In a die main body 25B having a V groove which performs folding processing for a work-piece in cooperation with a punch provided at an upper part thereof is provided a folding angle detection sensor 67 for detecting a folding engle of the work-piece. Further in the die main body 25B is provided communication means 75 that communicates by radio a detection value by the detection sensor 67 to a control device 95 comprising a press brake and also in the die main body 25B is provided power supply 79 for the communication means 75. At a lower part of the die main body 25B is provided an engagement part 25A that can be freely engaged with a die mounting groove 7 in the press brake and a die engagement groove 47 of the die stocker 27 in an ATC 11. At the engagement part 25A of the die main body 25B is provided a contactor 69 that can freely contact a power feeding plate 55 provided in the die engagement groove 47 of the die stocker 27, and the contactor 69 is connected to the power supply 79.SELECTED DRAWING: Figure 6 【課題】曲げ角度検出センサ、無線の通信手段及び充電式電池を備えたダイにおける前記充電式電池に容易に充電することのできるダイ及びダイストッカを提供する。【解決手段】パンチとの協働によってワークの折曲げ加工を行うＶ溝を上部に備えたダイ本体２５Ｂに、ワークの折曲げ角度を検出するための折曲げ角度検出センサ６７を備え、この検出センサ６７の検出値を、プレスブレーキに備えた制御装置９５に無線によって通信する通信手段７５を前記ダイ本体２５Ｂに備えると共に、この通信手段７５の電源７９を前記ダイ本体２５Ｂに備え、前記プレスブレーキにおけるダイ装着溝７及びＡＴＣ１１におけるダイストッカ２７のダイ係合溝４７に係脱自在な係合部２５Ａを前記ダイ本体２５Ｂの下部に備え、前記ダイストッカ２７の前記ダイ係合溝４７に備えた給電プレート５５に接触自在な接触子６９を前記ダイ本体２５Ｂの前記係合部２５Ａに備えると共に、当該接触子６９を前記電源７９に接続してある。【選択図】図６
