Edge pressing mechanism of high-speed can body stretcher

Abstract

The invention discloses an edge pressing mechanism of a high-speed can body stretcher. The edge pressing mechanism of the high-speed can body stretcher is characterized in that a cam follower, an edgepressing push rod, a thrust arm, a follower lever, an edge pressing force arm, an edge pressing slider and an edge pressing sleeve are successively arranged from an edge pressing cam according to a driving chain; a torque shaft is arranged at a turning point for the edge pressing force arm or/and the thrust arm; a first elastic element is arranged for the cam follower to force the cam follower topress tightly the edge pressing cam; and a second elastic element is arranged for the edge pressing sleeve to force the edge pressing sleeve to move in the pressing direction; directions of the forcetransmitted to the follower lever by the first elastic element and the second elastic element are opposite, and a sliding pin at a joint between the follower lever and the edge pressing force arm ismade to be located at the position of one end of an oblong hole. According to the edge pressing mechanism, first, the structure of an original edge pressing mechanism is greatly simplified, and the problem of poor synchronicity of driving of double edge pressing mechanism cams is overcome at the same time; second, maintenance is provided with convenience; and third, the sealing difficulty caused by a previous edge pressing push rod penetrating through an oil separator plate and the problem of serious mutual pollution between oil and emulsion are avoided.

Description

technical field [0001] The invention relates to can body stretching equipment, in particular to an edge-holding mechanism of a can body stretching machine working under high-speed stretching conditions (stretching speed 400 times / min). The so-called can body refers to a metal component having the shape of a can body, such as a can body of a pop can, a can body of a battery case, and other metal objects having a shape of a can body. Background technique [0002] Metal cans are widely used in people's daily life and industry. The typical ones are the can body of the pop can and the casing of the lithium battery in the power battery. The annual usage of these cans is very huge, especially the cans of pop cans. With the continuous improvement of people's living standards, the demand for pop cans is also increasing. [0003] Pop-top cans are usually made of aluminum and iron, and its structure is composed of a can body and an easy-open lid. Among them, the can body is formed by...
