Abstract
The utility model discloses an integral type lithium battery pole piece slitting cutter relates to shearing tool technical field, including the cutter body, its characterized in that, the cutter body is cylindrical structure, and the cutter body has seted up the assembly through-hole along the central axis, has seted up annular groove on the lateral surface of cutter body in the circumference; the annular grooves are uniformly distributed on the outer side surface of the cutter body at intervals in the axial direction, blades are formed between the end surfaces of the adjacent cutter bodies and the annular grooves and between the end surfaces of the adjacent cutter bodies and the adjacent annular grooves, and conical-surface-shaped knife edges are arranged on the outer edges of the blades. The utility model discloses an assembly error problem has easily appeared in having solved conventional scissors assembly process in the integral type design.
Description
Technical Field
The utility model relates to a shearing tool technical field especially relates to an integral type lithium battery pole piece slitting cutter.
Background
The quality of the battery pole piece serving as an important raw material of the lithium battery is the key point for ensuring the quality of the lithium battery, and the quality of the battery pole piece is greatly influenced by the slitting quality of the battery pole piece.
In the prior art, a rolling shear tool is generally adopted to shear and strip lithium battery pole pieces, and the rolling shear tool rolls on a plate to finish the theoretically infinite shearing action. The rolling shear cutter is generally assembled by a plurality of rolling shear blades, the positive and negative tolerance is controlled to be about +/-0.08 mm, assembly errors often occur in the assembly process of the rolling shear, and a cutter pad is difficult to place at the most proper position, so that the gap between each rolling shear blade is inconsistent and uneven, the gap between the rolling shear blades assembled on a main shaft is further inconsistent, the sizes and the sizes of cut products are inconsistent, the quality of the cut products cannot meet the requirements of customers, and the service life of the rolling shear cutter is also shortened.
Disclosure of Invention
An object of the utility model is to overcome the not enough of above-mentioned technique, provide an integral type lithium-ion battery pole piece slitting cutter, solved conventional roller shear assembly in-process and easily appeared assembly error problem.
In order to realize the purpose of the utility model, the utility model adopts the technical scheme that: the integral type lithium battery pole piece slitting cutter comprises a cutter body and is characterized in that the cutter body is of a cylindrical structure, an assembling through hole is formed in the cutter body along the central axis, and an annular groove is formed in the outer side surface of the cutter body in the circumferential direction; the annular grooves are provided with a plurality of strips, the strips are axially and uniformly distributed on the outer side surface of the cutter body at intervals, and blades are formed between the end surfaces of the adjacent cutter bodies and the annular grooves and between the adjacent annular grooves.
Further, the depth of the annular groove is higher than the thickness of the lithium battery pole piece required to be stripped.
Further, the width of the annular groove is equal to the width of the blade.
Further, a plurality of mounting holes are formed in the two end faces of the cutter body and used for mounting and fastening the rotating shaft to prevent looseness.
The utility model has the advantages that: adopt the integral type design, need not to reuse after a plurality of blade assembly, one has saved assembly time, has improved work efficiency, has avoided assembly error two, has improved life, during the use, only needs to insert specific rotation axis and can use in the assembly through-hole and through the mounting hole is fixed, convenient and fast is applicable to the continuous slitting of lithium-ion battery pole piece.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a perspective view of the present invention.
In the figure: the cutting tool comprises a cutting tool body 1, an assembling through hole 2, an annular groove 3, a mounting hole 4 and a blade 5.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
As shown in fig. 1-2, an integrated lithium battery pole piece slitting tool comprises a tool body 1, wherein the tool body 1 is of a cylindrical structure, the tool body 1 is provided with an assembling through hole 2 along a central axis, and an annular groove 3 is circumferentially formed in the outer side surface of the tool body 1; the annular grooves 3 are uniformly distributed on the outer side surface of the cutter body 1 at intervals in the axial direction, and blades 5 are formed between the end surfaces of the adjacent cutter bodies 1 and the annular grooves 3 and between the adjacent annular grooves 3; the depth of the annular groove 3 is higher than the thickness of the lithium battery pole piece to be stripped; the width of the annular groove 3 is equal to the width of the blade 5; a plurality of mounting holes 4 are formed in two end faces of the cutter body 1 and used for mounting and fastening the rotating shaft to prevent loosening.
The described embodiments are only some, but not all embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
