Embodiment

[0037] This embodiment provides a kind of stretching bending straightening equipment for the negative electrode substrate of Ni-MH battery, such as figure 1 shown, including: uncoiler, stretch bending leveler and winder;

[0038] Among them, the uncoiler and the winder are respectively arranged on both sides of the stretching and bending straightening machine. The stretching and bending straightening machine is equipped with bending rollers and leveling rollers. Bending rollers and leveling rollers of tensile bending straightening machines; such as figure 1 , the stretch bending straightening machine is composed of two sets of bending rolls 21 and one set of leveling rolls 22. The bending rolls are Y-shaped floating rolls with a roll diameter of 15mm. When the strip is bent on the rolls, its curvature radius is basically the same as the roll radius Likewise, the tensile stress of the strip can be reduced to reduce the breakage of the strip.

[0039] Moreover, a reverse bendi...

Abstract

The invention discloses stretch bending and straightening equipment for strips for nickel-metal hydride battery negative substrates, which comprises an uncoiler, a stretch bending straightener and a coiler, wherein the uncoiler and the coiler are respectively arranged on two sides of the stretch bending straightener; a bending roll and a straightening roll are arranged on the stretch bending straightener; a thermostat is arranged outside the stretch bending straightener and covers the bending roll and the straightening roll of the stretch bending straightener; and a reverse bending device is arranged between the coiler and the straightening roll of the stretch bending straightener. The equipment has the advantages of simple structure and high efficiency, ensures the flatness of the vertical surfaces of the strips and the straightness of the strips in the horizontal direction when processing 0.035mm ultra-thin strips, and makes the straightened materials completely meet the requirement of the 0.03500 ultra-thin nickel-metal hydride battery negative substrates and reach international advanced level.

Description

technical field [0001] The invention relates to stretching and bending straightening equipment for strip materials, in particular to a stretching and bending straightening equipment with a thickness of the negative electrode substrate of a nickel-hydrogen battery not greater than 0.035 mm. Background technique [0002] The substrate strip (stainless steel strip) for the negative electrode of the ultra-thin nickel-hydrogen battery with a thickness not greater than 0.035mm has high requirements on surface quality, dimensional tolerance, same-plate difference, surface unevenness, and mechanical properties, especially surface flatness. The requirements are getting higher and higher, and the user requires the surface flatness of the strip to be increased from the original 4mm / m to 0.5mm / m, which brings many difficulties to the control of the plate shape after rolling, and the product yield is low. Due to the change of the process, the equipment of the roll system is difficult to ...
