Operation and control method applied to machine tool die

Abstract

The invention relates to the field of machine tool dies, in particular to an operation and control method of a machine tool die. The method is achieved based on a die operation and control device, andthe die operation and control device comprises a stamping model, a damping mechanism, a lifting mechanism and a clamping mechanism, wherein a constant pressure mechanism is further fixedly arranged in the damping mechanism, and the clamping mechanism comprises a pull-down mechanism, a supporting box body, two first clamping devices and second clamping devices. According to a machine tool die stable replacement machine, the height of the stamping model is guaranteed, the same quality of machined workpieces is guaranteed, a numerical control punching machine is stable in use, and a large amountof working time of workers is prevented from being wasted; the first clamping devices and the second clamping devices are pulled through the pull-down mechanism to clamp the peripheral wall of the stamping model, the dislocation of the clamped stamping model is avoided, the adjustment by workers is avoided, the sum of stamping force can be adjusted through the constant pressure mechanism, and thequality consistence of the machined workpieces is further guaranteed.

Description

technical field [0001] The invention relates to the field of quick mold replacement devices, in particular to an operation and control method applied to machine tool molds. Background technique [0002] my country's patent application number: CN201811641628.4; discloses a quick mold replacement device for a CNC punch press, which can make the insertion rod be taken out from the inside of the fifth socket by sliding the sliding plate; The function of changing the punch model at any time effectively avoids the problem that the punch model is not easy to replace; the punch model can be fixed through the landing of the fixing plate; the stability of the punch model is effectively increased; the first buffer spring can be used The elastic force makes the fixed plate play a certain buffer role when it falls; it effectively avoids the phenomenon of damage to the fixed plate. [0003] my country's patent application number: CN201711391134.0; discloses a fixture base for CNC punchin...

Problems solved by technology

[0005] 1. Both of these two inventions have the effect of shock absorption on the fixture and stamping model on the CNC machine tool, but because the weight of different stamping models is different, when stamping models of different weights are installed on the CNC punching machine, the spring will be The degree of compression is different, and the punching stroke and punching force of the CNC punching machine are constant, which will make the punching force of the CNC punching machine too high or too low for different workpieces when punching the workpiece on the stamping die, and the quality of the processed workpieces is different. The use of the CNC punching machine is extremely unstable, and the spring in the equipment needs to be replaced when it needs to be adjusted, which wastes a lot of working time for workers

[0006] 2. In the second plan, the stamping model is transferred to the fixture through bolts, which is inconvenient to replace the stamping model. Although the first plan can clamp the stamping model, it only clamps the end faces on both sides of the stamping model. , the stamping model after clamping is prone to misalignment. After the misalignment, workers need to adjust it, which wastes a lot of working time for workers
