Problems solved by technology

"A Longitudinal Shearing Equipment for Steel Plates" (CN 01270262.5) discloses a shearing machine that integrates disc shears, crushed edge shears and side guides, and the waste edges cut by the disc shears still need to pass through the side guides Only when the bits are introduced can it enter the scrap trimmer, therefore, there is also a problem of poor import for the less rigid lead strip scrap

Embodiment 1

[0028] Disclosed is a disc shearing machine for fixing the width and cutting edges of lead belts for storage batteries. The lead belt for the storage battery is a lead-calcium alloy belt, and its thickness h is 2mm. The disc shears such as figure 1 , figure 2 As shown, the upper cutter shaft 2 and the lower cutter shaft 3 of the disc shears are respectively installed in the left frame 1 and the right frame 13 through bearings, and the left frame 1 and the right frame 13 are connected by a crossbeam 17 . The installation positions of the upper cutter shaft 2 and the lower cutter shaft 3 are parallel to each other, the upper cutter shaft 2 is installed above the frame, and the lower cutter shaft 3 is installed below the frame.

[0029] Such as figure 1 As shown, the upper knife shaft 2 is equipped with an upper width adjustment part 8, and the right side close to the upper width adjustment part 8 is fixedly equipped with an upper right blade 9, a right knife seat 10, a sprin...

Embodiment 2

[0042] Disclosed is a disc shearing machine for fixing the width and cutting edges of lead belts for storage batteries. Except following structure and technical parameter, all the other are with embodiment 1:

[0043] The upper cutter shaft 2 is installed below the frame, and the lower cutter shaft 3 is installed above the frame.

[0044] There is one piece of left scraping knife 5 and right scraping knife 14; the blade radius r of left scraping knife 5 and right scraping knife 14 碎 same. In this embodiment, the knife edge radius r 碎 Satisfies the following formula:

[0045] r 碎 =s-r 下 -(0.02~0.2)h

[0046] In the formula: s is the axial distance between the upper cutter shaft 2 and the lower cutter shaft 3, s=90mm;

[0047] r 下 is the radius of the lower left blade 7 and the lower right blade 12, r 下 =45mm;

[0048] h is the thickness of the sheared material, h=0.9mm.

[0049] The axial gap between the right side of the lower left blade 7 and the left side of the upp...

Embodiment 3

[0052] Disclosed is a disc shearing machine for fixing the width and cutting edges of lead belts for storage batteries. Except following parameter, all the other are with embodiment 1:

[0053] There are 3 to 4 pieces of the left scraping knife 5 and the right scrapping knife 14; the radius r of the right scraping knife 14 is 碎 The blade radius r of the left scraping knife 14 碎 same. In this embodiment, the knife edge radius r 碎 satisfy the following formula

[0054] r 碎 =s-r 下 -(0.02~0.3)h (1)

[0055] In the formula (1): s is the axial distance between the upper cutter shaft 2 and the lower cutter shaft 3, s=300mm;

[0056] r 下 is the radius of the lower left blade 7 and the lower right blade 12, r 下 =150mm;

[0057] h is the thickness of the sheared material h=4.0mm.

[0058] The axial gap between the right side of the lower left blade 7 and the left side of the upper left blade 6 is 0.2~1.0mm, and the axial gap between the left side of the lower right blade 12 a...

Abstract

The invention relates to a circle shearing machine capable of determining the width and smashing the edges of a lead belt for a storage battery. According to the technical scheme, an upper width adjusting component (8) is mounted on an upper knife shaft (2); an upper right blade (9) and a right knife holder (10) are sequentially fixedly mounted by means of being tightly adhered to the right side of the upper width adjusting component (8); 1-4 right edge smashing knifes (14) are mounted on the right knife holder (10); the knife opening of each right edge smashing knife (14) is located on the concentric circumference of the knife shaft (2); an upper left blade (6) and a left knife holder (4) are sequentially fixedly mounted by means of being tightly adhered to the left side of the upper width adjusting component (8); 1-4 left edge smashing knifes (5) are mounted on the left knife holder (4); the knife opening of each left edge smashing knife (5) is located on the concentric circumference of the knife shaft (2); a lower width adjusting component (11) is mounted on a lower knife shaft (3); a lower right blade (12) is fixedly mounted by means of being tightly adhered to the right side of the lower width adjusting component (11); and a lower left blade (7) is fixedly mounted by means of being tightly adhered to the left side of the lower width adjusting component (11). The circle shearing machine disclosed by the invention has the characteristics of less investment, convenience for installation and high shearing efficiency.

Description

technical field [0001] The invention belongs to a disc shearing machine for width-fixing and edge-breaking of metal strips, in particular to a disc shearing machine for width-fixing and edge-breaking of lead belts for storage batteries. Background technique [0002] The existing lead belt continuous casting and rolling production line for batteries is composed of lead ingot melting furnace, lead liquid holding furnace, continuous casting machine, continuous rolling unit, fixed-width shearing machine, edge crushing machine, coiler, etc., fixed-width shearing machine and The edge crusher is arranged separately. Since the rolled material is thin, the material is soft, the rigidity is very small, and the cut edge is very narrow, the guide of the edge before the edge crusher is often not smooth, resulting in the interruption of the production process. "A Longitudinal Shearing Equipment for Steel Plates" (CN 01270262.5) discloses a shearing machine that integrates disc shears, cru...
