Numerical control compressor model the choice that reachs a mould is direct the stand or fall that affecting craft to carry out quality. Reasonable and correct use model reach a mould, to improving machine tool productivity, the service life that prolongs mould and machine tool is having important sense, if use undeserved, the regular job that affects a machine tool. Model be to use installation pattern, its outfit is on rotary table, upper mould outfit going up on rotary table, lower mould outfit go up in next dial. Machine a requirement according to panel, consideration model the use that reachs a mould. (1) model compressor of domestic and international numerical control is opposite the norms that reachs a mould the standard that the machine of different type norms recommends to user place number and specifications are different, it is 9 ～ commonly 72 models, can install 9 ～ 72 moulds or more. Model the norms that reachs a mould and amount press a watch 3 choose. When choosing, dimension of the largest punched hole must not exceed this kinds of standard punching size scope, must not exceed machine nominal pressure. Express 3 it is the mould specification that compressor of ordinary numerical control can provide and amount. Express 3 models the norms that reachs a mould and quantitative model a scope of 123456 punching size (㎜) 80 ～ of Φ 50 ～ of 110 Φ 30 ～ of 80 Φ 12 ～ of 50 Φ 3 ～ of 30 Φ 12 centers Kong Mo number 2 (2) 2 (2) : The model that strong square opening and abnormity aperture are inside bracket several. (2) when mould clearance punching, the clearance between upper mould and lower mould basis board is thick with material property, by the watch 4 choose. Express 4 moulds clearance (㎜) board thick (㎜) aluminous stainless steel of material mild steel 0. 8 ～ 1.

9 (3) when the computation of punching power chooses a mould, ask the punching power of every mould must not exceed power of nominal of numerical control compressor. Punching power P can get by next type: P=100At τ (1) the P in type -- punching power (N) ; A -- mould point circumference (㎜) ; T -- plate thickness (㎜) ; τ -- MPa of plank shear strength. When punching, the mould is the smallest punching diameter presses a watch character according to plank material 5 affirmatory. Numerical control compressor can finish punching craft not only, and can finish the treatment craft such as shallow drawing, shutter, cut, embossing. With general drawing craft is contrary, the sunken model of shallow drawing craft is to install in upper mould go up, punch is to install in lower mould go up. Express 5 punching material of the smallest size is the least punching diameter / ㎜ mild steel 1.
