If the safe threshold values that the detected force value of power sensor is provided with more than or equal to system, solid-state relay cuts out, and breaks off the compacting loop of stamping machine, stops to press down, simultaneously the acousto-optic buzzer warning;
The 4th step, stamping machine go back up to original position, accomplish indicator lamp and light, and system provides whether qualified judgement of workpiece and statistical measurement workpiece number;
If the detected force value of power sensor is more than or equal to the qualified threshold values of system's setting and less than the safety threshold values, system shows " qualified ";
If the qualified threshold values that the detected force value of power sensor is provided with less than system, system shows " defective ", simultaneously the acousto-optic buzzer warning.
The technique effect that the present invention can reach is:
The present invention can gather average pressure and the maximum pressure of stamping machine in pressing process in real time.
The present invention adopts the power sensor, can accurately measure the operating pressure of stamping machine at a high speed.
The present invention can judge the whether qualified of stamping parts through the maximum pressure value or the average pressure value of stamping machine in the test stroke.
The present invention can adjust the test stroke through the thickness of adjustment catch.
The present invention has overload protection function.

Electromagnetic induction switch 4 is used to detect metal backup 5 and whether gets into its induction end.When metal backup 5 got into the induction end of electromagnetic induction switch 4, electromagnetic induction switch 4 was opened, and system begins to gather force value; When metal backup 5 was crossed the induction end of electromagnetic induction switch 4, electromagnetic induction switch 4 was closed, and system stops to gather force value.The stroke of the thickness decision systems gaging pressure of metal backup 5.
Electromagnetic induction switch 4 is through the DC power supply of 12V.
Electric control box 2 connects extraneous 220V AC power through Aviation Connector, by the 220V ac power supply.
Electric control box 2 is provided with solid-state relay, acousto-optic buzzer.
Solid-state relay is used for controlling the compacting loop of desk-top hydraulic pressure stamping machine.When the power sensor detected the safe threshold values that pressure is provided with more than or equal to system, solid-state relay broke off the compacting loop of stamping machine, stopped to press down, thereby reached the purpose of protection sensor.
Electric control box 2 is realized output through chip microcontroller control through the LCD LCDs, shows settings and operating result; Realize keying in through keyboard.
As shown in Figure 3, method for using of the present invention is:
1, starts desk-top hydraulic pressure stamping machine 1 and electric control box 2, get into parameter setting interface, according to the actual conditions setting technique parameter of waiting to press workpiece;
2, get into working interface, workpiece to be pressed is installed on the workbench of stamping machine; Accomplish indicator lamp and be in illuminating state;
3, press " compacting " button of stamping machine, stamping machine presses down, when metal backup 5 gets into the induction end of electromagnetic induction switch 4; Electromagnetic induction switch 4 is opened; The completion indicator lamp extinguishes, and removes last time whether qualified demonstration result, and system begins to gather force value through the power sensor; When metal backup 5 was crossed the induction end of electromagnetic induction switch 4, electromagnetic induction switch 4 was closed, and system stops to gather force value;
If the safe threshold values that the detected force value of power sensor is provided with more than or equal to system, solid-state relay cuts out, and breaks off the compacting loop of stamping machine, stops to press down, simultaneously the acousto-optic buzzer warning;
4, stamping machine goes back up to original position, accomplishes indicator lamp and lights, and system provides whether qualified judgement of workpiece and statistical measurement workpiece number.
If the detected force value of power sensor is more than or equal to the qualified threshold values of system's setting and less than the safety threshold values, system shows " qualified ";
If the qualified threshold values that the detected force value of power sensor is provided with less than system, system shows " defective ", simultaneously the acousto-optic buzzer warning.
