Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and particularly relates to a cutting component of a continuous casting and rolling production line for battery plates. Background Technique

[0002] Since lead-acid batteries have been mass-produced by using the continuous casting and rolling technology, because the continuous casting and rolling adopts a structure with the same thickness of the rib frame, which is different from the original gravity casting grid structure (the gravity casting grid structure is that the thickness of the grid frame is the same as the thickness of the lead paste, and the thickness of the rib is less than the thickness of the frame to avoid deformation problems during the cutting process of the battery plate), for the grid using the continuous casting and rolling technology, since the thickness of the lead paste is thicker than the thickness of the grid frame, and the strength of the frame structure is not high, the following problems will exist: 1) After the continuous casting and rolling battery plates are coated, because the cutting knife used is a structure of a straight arc knife, this knife exerts too much pressure on the battery plate frame during use, and there is no support at the cut of the battery plate during cutting, resulting in damage to the battery plate frame and loose lead paste after cutting; 2) The pressing plate is fixed by using hard threaded steel, and there is no buffer between the pressing plate and the cutting knife roller, and deformation is likely to occur during the cutting process. Therefore, it is urgent to study a cutting component of a continuous casting and rolling production line for battery plates to solve the above problems. Content of the Utility Model

[0003] The utility model aims to provide a cutting component of a continuous casting and rolling production line for battery plates, and the purpose is to solve the technical problems put forward in the above background technique.

[0006] As a preferred technical solution of the present utility model, the tops of the two support columns are connected by a horizontally arranged top plate; a pressing plate is horizontally arranged below the top plate; the opposite sides of the pressing plate are respectively in sliding contact with the two support columns; the pressing plate and the top plate are connected by a vertically arranged tension spring; bearing blocks are fixed on both opposite sides of the pressing plate; both bearing blocks are arranged on the lower surface of the pressing plate; a pair of pressing wheels are rotatably connected in parallel on the opposite inner sides of the two bearing blocks; the circumferential wheel surface of the pressing wheel abuts against the circumferential outer wall of the end of the slitting cutter roller.

[0007] As a preferred technical solution of the present utility model, one side surface of the cutter part and one side surface of the extension part are both flush with one side surface of the tool holder; the width of the cutter part along the axial direction of the slitting cutter roller is greater than the width of the extension part along the axial direction of the slitting cutter roller; the cutting edge of the cutter part and the supporting surface are both arc-shaped structures; the distance between the cutting edge of the cutter part and the central axis of the slitting cutter roller is greater than the distance between the supporting surface and the central axis of the slitting cutter roller; the end of the extension part far from the cutter part extends out of one end surface of the tool holder.
