As preferably, described slide block is provided with a lowering or hoisting gear, and the drive motors of this lowering or hoisting gear links to each other with described controller, and controller links to each other with a pressure sensor of being located in the said executing agency, and described controller also is provided with a clock unit.The instant pressure signal that pressure sensor obtains in comparing unit with the target mode transfer pressure of default; Instant pressure signal is excessive or too small; Promptly carry out work by DSP control lowering or hoisting gear, the height of adjustment mould is to reach the purpose of adjustment die pressure; During each the adjustment, DSP all carries out the adjustment of a chronomere.The control procedure of the utility model comprises the steps,
A. operator's target setting mode transfer pressure N
1, and be stored in memory cell;
B. start punch press, the pressure data when pressure sensor obtains executing agency's arrival lower dead point position, this pressure data is called instant pressure data, and the instant pressure data N of system sends into comparing unit, and comparing unit obtains target mode transfer pressure N from memory cell
1
C. comparing unit compares instant pressure data and target mode transfer pressure, when:
N≤N
1When [1-(1%～5%)], DSP control mode transfer motor rotates, and adjusts slide block downwards,
N
1[1-(1%～5%)]≤N≤N
1When [1+ (1%～5%)], system does not adjust,
N>=N
1When [1+ (1%～5%)], dsp system control mode transfer motor rotates, and adjusts upward slide block.
When adjusting slide block up or down, DSP is that unit adjusts to the rotation of motor control with 0.1-0.5 second, and instant pressure data of every acquisition is judged through system, adjusts like needs, then carries out the adjustment of a unit.
As preferably; As preferably, described slide block is divided into two up and down, and described lowering or hoisting gear comprises a reverse-flighted screw between two up and down of being located at slide block; Reverse-flighted screw is provided with a gear wheel coaxial with it, and gear wheel links to each other with motor through transmission mechanism.This reverse-flighted screw refers to it is that its two ends all have screw thread, and the spiral shell at two ends is on the contrary, when it rotates, slide block up and down two can close up or separately, reach the purpose of up-down.
As preferably, described transmission mechanism comprises a high gear of the mould that links to each other with drive motors, and this gear wheel and the high gear of mould are suitable, and the high gear of mould is located at the power output rod of mode transfer motor, and this mode transfer motor is fixed in slide block.Because the high gear of mould is less, during the angle of the moving tooth of its revolution, the corresponding rotation of gear wheel is less, and number of teeth counter to be the rotation number of teeth with the high gear of mould serve as counting basis, therefore, this control system is higher to the high computational accuracy of mould.
As preferably, described upper end of slide block is provided with an overload grease chamber, and described connecting rod lower end is provided with bulb, and this bulb is in the overload grease chamber, and described pressure sensor is located in this overload grease chamber.Because the pressure size of mould directly is reflected in the load grease chamber, judge that through this load grease chamber die pressure is very accurate.
The beneficial effect of the utility model is; It realized a kind of can the utmost point time, adjust the punching machine mold height accurately; Thereby reach the high adjustment automatically of punch press mould, after die pressure surpasses the protection force value, promptly it is carried out brake operation simultaneously, reached protective effect mould.
