Punching device for strip-shaped material strip

Abstract

The invention provides a punching device for a strip-shaped material strip. Through the punching device, it can be guaranteed that a punching arm of a punching machine and a stepping motor of a feeding clamping mechanism are synchronous in frequency. The punching device comprises the punching arm and a punching die set connected with the lower portion of the punching arm. The die set is provided with a die pressing area. The die pressing area is connected with a feeding device in the feeding direction. The feeding device comprises a feeding track and feeding clamping mechanisms. The feeding clamping mechanisms are arranged on the two sides of the feeding track and driven through the stepping motor. The punching arm is fixedly connected with a synchronous drive arm. The stepping motor is provided with a rocker type switch. The rocker suspension end of the rocker type switch is located in the stroke of the synchronous drive arm. According to the punching device, it can be guaranteed that the punching arm and the stepping motor of the feeding clamping mechanisms are synchronous in frequency, accordingly the error of the feeding distance in the punching process is reduced, the precision of the feeding distance is guaranteed, and material waste is avoided.

Description

technical field [0001] The invention relates to the technical field of punching machinery, in particular to a punching device for a strip material strip. Background technique [0002] At present, the temperature-sensing sheet of the temperature controller of an electric rice cooker is generally stamped into a circular blank through a strip-shaped thin steel strip. The raw material of the strip-shaped thin steel strip is generally in the shape of a coil. When stamping, the strip-shaped thin steel strip needs to be pulled out and sent into the die area of ​​the stamping die set of the stamping machine. The existing production line generally clamps the strip-shaped thin steel strip by the feeding clamping mechanism driven by a stepping motor and sends it into the die area. According to the standard configuration frequency of the stamping machine, calculate and set the frequency of the stepping motor and the forward distance of each feeding of the feed clamping mechanism. Due ...

AI Technical Summary

Problems solved by technology

Due to the aging of the punching machine or other reasons, there is an error between the actual punching frequency of the punching machine and the standard configuration frequency. In this way, the calculation method based on the standard configuration frequency will affect the accuracy of the feeding distance in the punching process, and it is easy to accumulate errors and waste materials.
