Abstract
The utility model provides a blade shearing machine cutter, includes cutter body and cutting edge portion, cutting edge portion sets up in cutter body one side, the domatic and bottom surface contained angle of cutting edge portion is 15, cutting edge portion is domatic to be connected with the cutter body with the fillet, the cutter body is provided with the mounting hole, cutting edge portion and cutter body be integrated into one piece. The cutter has simple structure and is easy to process. The knife edge is adjusted to be 15 degrees, the length of the knife edge is lengthened, stress points are avoided, the defects of the lens are reduced, the internal crack rate of the cut is reduced, the load output rate of the lens is improved, and the reject ratio of the lens is reduced. The mounting hole is improved, so that the machine adjusting time is greatly reduced, and the working efficiency is improved.
Description
Technical Field
The utility model relates to a cutter, especially an optical lens shear blade cutter.
Background
The plastic lenses after injection molding need to be cut by a cutter on a lens cutting machine, and the corresponding lenses in each hole are cut by the cutter and are placed on corresponding material trays. Its cutting edge of cutter that uses at present is mostly ladder angle, and effective length is shorter and the angle is too big during the shearing, because there are some lenses of "the thick on limit" at present, when leading to shearing, leads to the lens internal crack, and the lens outward appearance can't reach standard, reduces the lens yield.
Disclosure of Invention
An object of the utility model is to provide a blade shearing machine cutter, this cutter can improve the lens and go out the lotus rate, reduces the lens defective rate.
The technical scheme of the utility model lies in: the utility model provides a blade shearing machine cutter, includes cutter body and cutting edge portion, cutting edge portion sets up in cutter body one side, cutting edge portion's domatic and bottom surface contained angle is 15, cutting edge portion's domatic and cutter body are connected with the fillet, the cutter body is provided with the mounting hole, cutting edge portion and cutter body be integrated into one piece.
Further, the blade part is equal to the cutter body in length.
Further, the cutting edge part is a right-angle triangular prism, and the cutter body is a cuboid.
Further, the mounting hole is a straight notch.
Compared with the prior art, the utility model has the advantages of it is following: the cutter has simple structure and is easy to process. The knife edge is adjusted to be 15 degrees, the length of the knife edge is lengthened, stress points are avoided, the defects of the lens are reduced, the internal crack rate of the cut is reduced, the load output rate of the lens is improved, and the reject ratio of the lens is reduced. The mounting hole is improved, so that the machine adjusting time is greatly reduced, and the working efficiency is improved.

Detailed Description
In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to FIGS. 1-4
The utility model provides a blade shear machine cutter, includes cutter body 100 and cutting edge portion 200, cutting edge portion sets up in cutter body one side, cutting edge portion's domatic 201 and bottom surface 202 contained angle is 15, cutting edge portion's domatic and cutter body are connected with the fillet, cutter body is provided with mounting hole 300, cutting edge portion and cutter body be integrated into one piece.
In this embodiment, in order to facilitate the cutting and ensure the strength of the cutter, the blade portion is equal to the cutter body in length.
In this embodiment, for the convenience of manufacturing, the cutting edge portion is a right-angled triangular prism, and the cutter body is a cuboid.
In this embodiment, in order to facilitate the installation of the cutter and reserve the machine adjusting space, the mounting hole is a straight notch.
When the cutter is used, the cutter is used in pairs and is divided into an upper cutter and a lower cutter, the two cutters are respectively fixed on an upper cutter bar and a lower cutter bar of a sheet shearing machine, and the positions of the cutters are adjusted to accord with shearing parameters.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
