Embodiment Construction

[0030] The present invention as figure 1 , 2 As shown: the CNC turret punch press includes hydraulic drive cylinder 1, punch 2, striking head 4, upper die 5, lower die and controller, and also includes interconnected punching force tracking collector, punching force signal acquisition and conditioning A circuit and a control circuit, the control circuit is connected to the controller; the stamping force tracking collector is arranged at a force transmission position above the upper die 5 .

[0031] The first embodiment of the present invention is as figure 1 As shown, the punching force tracking collector is a force sensor 3, and the force sensor 3 is arranged between the punch 2 and the striking head 4, and collects the axial force that the punching force reacts on the striking head. The force sensor 3 is connected to the control circuit. The load cell 3 can choose dynamic pressure sensors with different signals according to the requirements of different tonnages.

Abstract

The invention relates to a system for detecting the wear of a mould of a numerical control turret punch press on line and a working method of the system. The system can adapt to the actual punching condition can acquire the online punching force data reliably and can judge the working condition of the mould. The numerical control turret punch press comprises a hydraulic driving cylinder, a punching head, a striking head, an upper die, a lower die and a controller and also comprises a punching force tracking collector, a punching force signal collecting and conditioning circuit and a control circuit which are connected one another. The control circuit is connected with the controller. The punching force tracking collector is arranged in the force transferring position on the upper die. According to the technical scheme of the invention, the system can adapt to the actual punching condition, can bear the pulse impact load, can acquire the online working pressure value reliably and can meet the full-automatic production requirement hereby.

Description

technical field [0001] The invention relates to the technical field of automation of a numerically controlled turret punch press, in particular to an on-line detection system and a working method for die wear of a numerically controlled turret punch. Background technique [0002] The mold on the CNC turret punching machine will wear out after a long time of use, resulting in increased punching force, or due to the quality of the mold itself, it will also break and crack during the stamping process, resulting in stamping The quality of plate processing is abnormal, which will cause damage to machine tools and molds in severe cases. Even in stand-alone production operations, with an operator next to the machine tool, it is difficult to detect mold problems in time, and a large amount of waste and defective products will be generated. With the improvement of automation requirements, the automatic sheet metal processing production line is basically in an unattended state, and i...
