Description

Technical Field

[0001] The utility model relates to battery accessories processing equipment, in particular to a knife head transmission device for a flying shear cutting machine. Background Art

[0002] The new energy battery core shell cutting machine is a key equipment for the production of battery core shells. It can be used to cut linear battery core shells to provide the basic materials for finished battery core shells. The production requirements of this equipment are extremely demanding, such as the verticality of the shell mouth and its smoothness and burr requirements. Due to the heat dissipation requirements of the battery core shell, the aluminum foil products are very thin, with a thickness of only 0.35-0.5mm. During the cutting process, there will be pits at the blade, and a slight deviation will cause the core shell mouth to deform greatly, the cut surface to be rough, the smoothness to be poor, or the verticality of the cut surface to be substandard, thereby generating waste. The above problems The key point of the problem lies in whether the concentricity of the drive shaft of the cutting equipment handle meets the standard. The current cutting machine transmission structure is a polygonal transmission shaft. This type of transmission structure always has multiple side lengths with tolerances, and the friction coefficient is large. Under the combined action of the rotation and sliding of the transmission shaft, when the cutting handle is rotating to cut the battery core shell, there will be great resistance when the trolley moves left and right and twists the cutting die on the trolley, which affects the smooth movement of the trolley and the knife head will shake and jam when working. Therefore, improving the stability of the flying shear cutting machine transmission device is of great help to improving product quality. Utility Model Content

The trolley is slidably connected to the linear slide rails through the slide seat.

[0007] The middle part of the trolley is connected with the rotating cutter head seat through a deep groove ball bearing, and the trolley slides on the slide rail to drive the rotating cutter head seat to slide on the transmission shaft.
