Cam box structure of material transferring mechanism for battery shell stamping

Abstract

The invention discloses a cam box structure for a material transferring mechanism for battery shell stamping. The cam box structure comprises a box body, a drive shaft is rotatably connected to the box body, and a cam with a disc-shaped structure is fixedly connected to the drive shaft; the outer edge of the cam is a curved contour, the cam is eccentrically arranged on the drive shaft, and the eccentricity distance is equal to the step distance of a progressive die; the cam is horizontally arranged in a box body, a sliding connection plate is slidably connected in the box body, the sliding connecting plate is horizontally arranged, and the sliding connecting plate is located at the lower part of the cam; a first bearing and a second bearing are arranged on the positions, on both sides of the cam, on the upper end surface of the sliding connecting plate; and when in operation, the curved contour of the cam meshes with one of the first bearing and the second bearing. The cam box structure has the characteristics of small volume and simple structure, the cam box adopting the cam box structure can realize transmission of power between a spindle of a punch press and the cam box only bya vertically arranged transmission shaft, and the structure is greatly optimized.

Description

technical field [0001] The invention relates to the field of stamping equipment, in particular to a cam box structure of a material transfer mechanism for stamping a battery case. Background technique [0002] At present, in the continuous punching production process of battery cases using progressive dies, the progressive feeding between adjacent stations is mostly realized through the material transfer mechanism. The motion is converted into linear reciprocating motion, however, the cam box structure of the existing material transfer mechanism for battery case punching is as follows: figure 1 As shown, the cam box structure of this kind has a large volume, and the cam 11 is difficult to process and takes a long time. It needs to be milled out on its circumferential surface as a whole. Its camshaft 12 is parallel to the slide shaft 13, both of which are arranged horizontally, and the main shaft of the punch press is above the punch press. Therefore, a vertically arranged v...
