Multi-station punching machine, feeding assembly and feeding method

Abstract

The invention relates to a feeding assembly which is used for a multi-station punching machine. The feeding assembly comprises a rack, a servo motor, an eccentric wheel, a connection rod, a slide block and slide strips, wherein the servo motor is fixedly connected with the rack; the center of the eccentric wheel is fixedly connected with an output shaft of the servo motor; one end of the connection rod is hinged with the output end of the eccentric wheel; the slide block is hinged with the other end of the connection rod and is slidingly mounted on the rack; the slide strips are distributed on the two sides of a punching station, are fixedly connected with the slide block and are provided with mechanical arms. The feeding assembly is not influenced by a bottom dead center of a punching machine bent axle so that the vibration in a feeding process is avoided and the feeding stability is improved; compared with the prior art, the rotation process of the servo motor is more stable so that the feedings speed can be properly improved under the precondition that the rotation process is matched with a punching beat, and furthermore, the feeding efficiency is improved. The invention further discloses a multi-station punching machine with the feeding assembly and a feeding method applied to the feeding assembly.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a multi-station punch, a feeding assembly and a feeding method. Background technique [0002] Multi-station punching machine is a stamping equipment commonly used in the manufacturing process of mechanical parts. According to the different parts produced, there are generally multiple stations with different numbers on it. The workpiece needs to be stamped at each stamping station before it can be processed. to get the finished product. [0003] For example, in the production process of the retainer, a multi-station punching machine is required. The multi-station punching machine is equipped with a feeding assembly. The retainer that needs to be stamped is first placed on the first stamping station. After the stamping operation is completed, it will be sent to the next stamping station under the action of the feeding assembly. When the stamping operation is compl...
