Punch forming mechanism

Abstract

The invention discloses a punch forming mechanism. The punch forming mechanism comprises a material pulling machine located at the rear end of punching equipment, a carrier film feeding roll and an aluminum strip feeding roll, wherein the carrier film feeding roll and the aluminum strip feeding roll are arranged at the front end of the punching equipment, an aluminum strip on the aluminum strip feeding roll is located above a carrier film, the carrier film and the aluminum strip are driven by the material pulling machine to penetrate through the punching equipment, the punching equipment comprises an upper die and a lower die which are arranged on the base, a punching protruding part, a leveling and pressing part and an appearance cutting and pressing part which correspond to each other are sequentially arranged between the upper die and the lower die, the aluminum strip sequentially passes through the punching protruding part, the leveling and pressing part and the appearance cutting and pressing part from the upper end face of the lower die, a lifting device is arranged in the lower die, the carrier film passes through the bottom of the lower die and leads to the lifting device through a guide device, and an aluminum strip waste guide plate and a finished product guide plate are arranged at an inlet of the material pulling machine. According to the punch forming mechanism, the wire drawing lines of the punched aluminum sheet are consistent with the length direction of the carrier film, the quality of the finally formed aluminum sheet is ensured, and the requirements of customers are met.

Description

technical field [0001] The invention relates to the punching field, in particular to a punching and forming mechanism. Background technique [0002] The finished aluminum strip needs to attach multiple aluminum sheets on the carrier film, and each aluminum sheet needs to be pre-processed into a rectangular shape with a protrusion in the middle before attachment. At present, the aluminum strip is first punched into a rectangular aluminum sheet with protrusions, and then the multiple aluminum sheets are collected and then bonded by a placement machine. This method is inefficient. In order to solve this problem, equipment with automatic punching and forming devices has emerged, such as the 2021-02-09 announcement, the Chinese utility model patent with the authorized announcement number CN212494866 U, which discloses a cross-shaped punching and forming device, With this structure, the aluminum strip can be punched and directly attached to the carrier film through the cross-shap...

AI Technical Summary

Problems solved by technology

After the aluminum strip and the carrier film are fed and punched in a cross shape, the aluminum sheet can be attached to the carrier film, but because there are wire-like lines on the aluminum sheet, after cross-shaped punching, the lines on the aluminum sheet and the length direction of the carrier film ( Direction) is inconsistent, which leads to poor performance of the stamped aluminum sheet
