Fault detection mechanism for progressive die of motor core

Abstract

A fault detection mechanism for a progressive die of a motor core comprises a minitype travel switch, a fault feeler lever, a fault sliding head and a fault correcting pin, wherein the minitype travel switch, the fault feeler lever, the fault sliding head and the fault correcting pin are connected with a machine tool controller. The minitype travel switch is fixed to an upper die base provided with a guide pin. The trigger end of the minitype travel switch makes contact with the end, close to the minitype travel switch, of the fault feeler lever, and a bulb structure of the other end of the fault feeler lever makes contact with a side face clamping groove of the fault sliding head sliding along a first through hole of the upper die base. The tail end of the fault correcting pin stretches out of a through hole of a stripper plate. The fault correcting pin and the guide pin are arranged in parallel, and a guide pin insertion hole and a fault correcting pin insertion hole are formed in the corresponding positions of the lower die base and a female die. The fault detection mechanism for the progressive die of the motor core has the advantages that the phenomena that waste workpieces are generated and stamping cannot be carried out normally when mis-feeding and uncompleted feeding occur in a high-speed automatic punching process of the progressive die are avoided, the service life of the progressive die is guaranteed, and the fault detection mechanism for the progressive die of the motor core is suitable for match production of various motor cores, and the quality of punched motor cores is improved.

Description

technical field [0001] The invention relates to an error detection mechanism for a motor iron core progressive die. Background technique [0002] In the motor industry, the stator and rotor cores are important parts of the motor. The technical requirements of the stator and rotor cores are relatively high, and the production batches are relatively large. Generally, the motor iron core is produced by automatic feeding and automatic stamping progressive die. The motor iron core progressive die is stamped through each process step, and finally a stamped product is obtained. The distance between each process step is called step. distance. In the automatic stamping process, the accuracy of the step distance between each station is relatively high, and the step distance positioning method generally adopts the automatic feeding device on the punching machine to complete the initial positioning, and the guide pin on the progressive die is used for the final fine positioning. Its p...

Problems solved by technology

[0003] The present invention aims at the occurrences of current motor iron core progressive dies such as misfeeding of materials, inadequate feeding, lamination, material arching, errors in thickness or width of materials, parts not ejected or In order to solve the problem of whereabouts and other problems, a motor core progressive die error detection mechanism is proposed to prevent the punching of the punch and the die, which protects the progressive die and prevents the production of large quantities of waste products.
