Embodiment Construction

[0026] See Figure 1~ Figure 11 , the present invention provides double-sided microporous burr steel perforation equipment based on the principle of double-wheel pair-roller perforation. and so on. The descriptions are as follows: Automatic belt unwinding system A: This system consists of a belt unwinding frame 2, a constant tension mechanism 3, a broken belt protection mechanism 4, and a mechanical power mechanism 20. The mechanical power mechanism is composed of a motor and a reducer. Frame 2 central shafts are connected, together set up on its frame 17 with belt rack 2, constant tension mechanism 3 is installed on the frame beside this belt rack 2, a group of guide wheels 18 are respectively housed in its front and rear The E support is an M-shaped path, and the electronic ruler elastic stick of the constant tension mechanism 3 is pushed against the upper side of the lower middle of the M-shaped path, and the frequency of the motor of the mechanical power mechanism is cont...

Abstract

The invention provides a double-side micro-hole burr steel belt and manufacturing method and device thereof, wherein the double-side micro-hole burr steel belt molding device is invented based on the principle of holing by the double rollers opposite rolling, and the key is that the invention uses a group of holing rollers instead of traditional convex and concave die structure, and the holing rollers are in pure rolling state, the steel belt passes through the rollers form the gap between the rollers to be holed to form micro-holes, the burrs on the hole edge are respectively bended to opposite to from fiber-shaped burr on the surface of the steel belt. The holing rollers can be divided into two types, one type roller is equably disposed with geometrical teeth, whose shapes includes rectangle, taper, trigon or pyramid, on its surface, and another type roller is provided with geometrical annular slot, whose slot angle is trigon or rectangle, on its surface; according to the process requirement, the rollers can combine with that of another type, or combines with that of the same type. The holed steel belt made in this manner has hole shape arranged in various forms, and the hole diameter is very small and compact, the density of the burr hole is up to 625 pre square centimeter, and the burr on the surface of the steel belt is fiber-shaped; and the production speed is 20 times faster than that of the traditional punching die.

Description

technical field [0001] The invention relates to a special production device for manufacturing secondary battery polar plate skeletons. The double-sided microporous burr steel strip (three-dimensional strip) processed by it has small and fine holes, and the flanging burrs on the surface of the steel strip are in the shape of three-dimensional fibers. The key material of the positive electrode framework of Ni-MH and Ni-Cd batteries. Background technique [0002] At present, the double-sided burr steel strip used to manufacture the secondary battery plate skeleton is produced by stamping, that is, the punch is equipped with a special production mold, and the mold is mainly composed of a bottom plate, a pressing plate, a punch (punching needle), a concave It is composed of modules, jumping devices and other parts. However, there are serious defects in the products produced by this method: ① large pore size, it is difficult to punch microporous products; ② large hole spacing, lo...
