Lithium battery casing stretch forming machine

Abstract

The invention provides a drawing and forming machine of a lithium battery shell. The drawing and forming machine comprises a rack, a die mechanism, a shell punching mechanism and a shell transferring mechanism, wherein the die mechanism and the shell punching mechanism are arranged on the rack, the shell transferring mechanism is arranged between the die mechanism and the shell punching mechanism, the die mechanism comprises a die installation seat, a plurality of concave dies are horizontally arranged on the die installation seat side by side, openings of the plurality of concave dies face towards the same side, and the widths of the plurality of concave dies are gradually reduced in sequence; the shell punching mechanism comprises a plurality of punching rods which respectively correspond to the plurality of concave dies, and the plurality of punching rods are horizontally arranged side by side; the shell transferring mechanism comprises a plurality of feeding clamps which are used for clamping and transferring the shell, a shell transferring bottom plate which is used for installing the feeding clamps and a second driving element which is used for driving the shell transferring bottom plate to feed the shell back and forth, the feeding clamps can be arranged on the shell transferring bottom plate in an opening and closing mode, and the plurality of feeding clamps are horizontally arranged side by side. According to the drawing and forming machine, a traditional vertical drawing mode is changed into a horizontal drawing mode, so that the cost and overall size of equipment are reduced, and the equipment is convenient to assemble and use.

Description

technical field [0001] The invention relates to a stamping and stretching device for a lithium battery casing, in particular to a stretching forming machine for a lithium battery casing. Background technique [0002] Existing battery shell stretching machines are generally of vertical structure, that is, the forming die is set at the bottom, and the punch for pushing the shell to the forming die is set at the top. When working, the punch pushes the shell downward into the forming die Punch the hole so that the shell is stretch-formed. In order to facilitate the punched shell to be removed from the punched hole, the punched hole is generally provided with a spring that impels the shell to move upward. Sufficient punching pressure requires the addition of high-power stamping equipment, which increases the cost and overall volume of the equipment, making the overall weight of the equipment reach 110-160 tons, which is not conducive to the layout of the production line and the ...
