Mold limiting mechanism and application method thereof

Abstract

The invention discloses a mold limiting mechanism. The mold limiting mechanism comprises limiting mechanisms; the limiting mechanisms are mounted on the peripheral side walls of a mold; the limiting mechanisms comprise limiting blocks, connecting blocks and springs; the connecting blocks are connected to the side walls of the mold; the connecting blocks are provided with U-shaped grooves; the limiting blocks cooperate with the U-shaped grooves; and the springs are arranged in the U-shaped grooves. One ends of the springs are connected with the bottoms of the U-shaped grooves, and the other ends of the springs are connected with the bottoms of the limiting blocks; the limiting blocks are slidingly connected to the connecting blocks through the springs and the U-shaped grooves; the tops of the limiting blocks are higher than the tops of the side walls of the mold; one sides of the limiting blocks are bonded with the peripheral side walls of metal plates placed on the mold; the side wallsof the metal plates are clamped between the limiting blocks and the side walls of the mold; and at this time, the limiting blocks and the side walls of the mold form clamping mechanisms to limit movement of the metal plates in the horizontal direction, so that the stability of all parts in an edge rolling process is improved, and the edge rolling quality is improved. The invention further discloses an application method of the mold limiting mechanism.

Description

technical field [0001] The invention belongs to the technical field of auto parts manufacturing, and in particular relates to an auxiliary mechanism of a tire mold robot, in particular to a method for using a tire mold limiting mechanism, which is used in the rolling process of automobile sheet metal. Background technique [0002] At present, in the automobile welding industry, the robot roll edge process is mainly applied to the front and rear doors, engine cover, trunk lid, top cover and side wheel cover area. In this application document, the front and rear doors, engine cover, trunk cover , top cover and side wall are collectively referred to as sheet metal. Ordinary tire mold limit mechanism, through the cylinder to drive the limit mechanism to close to achieve the purpose of limit. Before the roller head rolls to this position, the cylinder needs to drive the limit mechanism to open in advance. In order to ensure the quality of the sheet metal roll edge, it is common ...

AI Technical Summary

Problems solved by technology

In order to ensure the quality of the sheet metal roll edge, it is common to rely on increasing the number of cylinders to drive more limit units to increase the stability of the assembly and limit its movement, but this leads to increased costs and a waste of production cycles.
