Abstract

The invention discloses an angle recognition method and an angle recognition device for a cutting die on a punch press. The angle recognition method comprises the following steps: acquiring a standard cutting die diagram and a target diagram with angle recognition needs; coinciding the gravity center of the target diagram with the gravity center of the standard cutting die diagram; rotating the target diagram around the gravity center, and calculating the coincidence degree of the standard cutting die diagram and the target diagram while rotating a unit angle each time; and taking the rotating angle of the target diagram as the angle of the cutting die when the value of the coincidence degree is minimum. According to the invention, the gravity center of the target diagram with angle recognition needs is coincided with the gravity center of the standard cutting die diagram; the coincidence degree of the standard cutting die diagram and the target diagram is calculated in an angle rotating manner; and the rotating angle of the target diagram is taken as the angle of the cutting die when the value of the coincidence degree is minimum. Therefore, the angle deviation of the cutting die mounted on the punch press can be identified, and interference of any other added device is avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method and device for identifying the angle of a die on a punching machine. Background technique [0002] A punch press is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, and low technical requirements for operators compared with traditional machining, so its use is becoming more and more extensive. Stamping production is mainly for sheet metal. Through molds, it can make blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting and extrusion parts, etc., which are widely used in various fields. [0003] The die used in the punching machine is made according to precise drawings. When the die is installed on the punching machine, some auxiliary devices, such as foam, will be added; in order to determine whether the angle of die installation is consistent ...
