Abstract

The invention discloses a shearing machine for a substrate strip for manufacturing a nickel-hydride battery cathode, comprising: an uncoiler, a material transfer plate, a slitting mill, a side material coiling machine, a tension table, a crimping machine, a hydraulic station, a hydraulic oil cylinder, an electrical box and an electric control cabinet; a material guide device on the slitting mill is formed by matching of an upper guide plate and a lower guide plate, which are made of special materials and have special shape; a rolling shear on the slitting mill is composed of an upper hob and a lower hob, which are both cylindrical, the lower hob is provided with a ring-shaped opening groove matched with the upper hob, and depth of cut formed by matching of the upper hob and the lower hop is not less than 0.2mm. By cooperation of the uncoiler and the material guide device of a shearing device with the specially structured rolling shear, the side material coiling machine and the crimping machine, the shearing machine can shear an ultra-thin steel strip for manufacturing the nickel-hydride battery cathode, wherein thickness of the ultra-thin steel strip is not more than 0.035mm, so that shearing precisions of camber, width error, burr, flatness and the like all meet requirements, and the shearing machine has simple structure and simplified shearing technology.

Description

technical field [0001] The invention relates to a shearing device, in particular to a shearing device for making an extremely thin steel strip with a thickness not greater than 0.035mm for making a negative electrode substrate of a nickel-hydrogen battery. Background technique [0002] The current shearing machine for cutting steel strips is composed of an uncoiler, a rolling shear, a side material winder and a coiler, etc. setting, each equipment cooperates to form a shearing unit. This shearing unit can only be used because the speed of the side material winding machine and the hob is not completely synchronized, there is no gap between the upper and lower guide plates of the material guide port, and the adjustment range of the winding tension is small. For cutting steel strip materials with a thickness of more than 0.1mm, the cutting accuracy is: (1) sickle bend is not greater than 6.25mm / 3m; (2) 1.2 width error is not greater than 0.035mm; (3) 1.3 burrs are not greater t...
