Description

CNC cutting die for cutting PC board

Technical Field

The application relates to the technical field of CNC cutting die, especially, relate to a CNC cutting die for cutting PC board.

Background

At present, for cutting of a PC (polycarbonate) plate material, an upper cutting die and a lower cutting die are commonly adopted in a traditional process for opposite punching to finish punching of the plate material; however, a large amount of burrs exist on the edge of the product cut by the method, and the burrs need to be processed again at a later stage, so that the processing cost is increased; and the cutting dies are opposite to each other, so that the blade is easy to damage, and the service life of the cutting dies is short.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a CNC cutting die for cutting PC board to solve product deckle edge phenomenon, improve cutting die life. The following technical scheme is adopted:

a CNC cutting die for cutting a PC plate comprises a knife handle and a blade, wherein the blade is arranged at the end part of the knife handle; one end of the blade, which is far away from the knife handle, is provided with a cutting part, and the height of the cutting part is smaller than the thickness of the plate to be cut; an inclined part is arranged on one side of the blade away from the central axis of the tool holder and used for cutting the edge chamfer of the plate; slope one end links up in cutting part, and the other end outwards inclines towards keeping away from the handle of a knife axis.

Optionally, the width a of the cutting portion is 1.24mm-1.25mm, and one side of the blade close to the central axis of the knife handle coincides with the central axis of the knife handle.

Optionally, the height h of the cutting portion is 0.59mm-0.6mm.

Optionally, an included angle β between the inclined portion and the central axis of the tool holder is 45 °.

Optionally, the maximum width of the blade is 2mm.

Optionally, the blade thickness is 0.6mm.

Optionally, the end part of the tool holder close to the blade is of a truncated cone structure.

Optionally, the diameter of the tool shank is 6mm.

Optionally, the length of the knife handle is 39.09mm-39.19mm.

To sum up, the present application includes the following beneficial effects:

1. by arranging the cutting part and the inclined part of the blade, chamfers are cut on the edges of the product, so that the generation of burrs is reduced, the cutting quality of the product is improved, and the processing cost can be reduced; the cutting is carried out by high-speed rotation of a single blade, and compared with the traditional mode that two blades are used for opposite punching for cutting, the service life of the cutting die can be prolonged; the service life of the cutting die can be prolonged by adopting the blade made of the artificial diamond material;

2. the width of the cutting part is 1.24mm-1.25mm, and the waste generated in cutting is reduced while the blade is ensured to have enough strength.

Detailed Description

The present application is described in further detail below with reference to the attached drawings.

The embodiment of the application discloses a CNC cutting die for cutting PC board, including handle of a knife 1 and blade 2, wherein handle of a knife 1 adopts the tungsten steel material, and blade 2 adopts artificial diamond material. One end of the blade 2 is embedded and fixed in the end part of the handle of the knife 1, the blade 2 is positioned on one side of the central axis of the handle of the knife 1, and one side edge of the blade 2 close to the central axis is coincided with the central axis. One end of the blade 2, which is far away from the knife handle 1, is provided with a cutting part 3, and the height of the cutting part 3 is higher than the thickness of the plate to be cut; one side of the blade 2, which is far away from the central axis of the tool holder 1, is provided with an inclined part 4 for chamfering the edge of the cut plate; one end of the inclined part 4 is connected with the entering part, and the other end inclines outwards towards the central axis far away from the knife handle 1.

Specifically, the maximum width of the blade 2 is 3mm. The blade 2 has a thickness of 0.6mm. The width a of the cutting part 3 is 1.24mm-1.25mm, and the waste generated by cutting is reduced while the strength of the blade 2 is ensured. In this example, the thickness of the PC board material is 0.64mm. The height h of the cutting part 3 is 0.59mm-0.6mm. The included angle beta between the inclined part 4 and the central axis of the knife handle 1 is 45 degrees. Wherein, the height of the cutting part 3 is set to be smaller than the thickness of the plate, so that the inclined part 4 can cut out a chamfer to the edge of the plate in the cutting process. The end part of the knife handle 1 close to the blade 2 is provided with a frustum structure. The diameter of the tool shank 1 is 6mm, and the length of the tool shank 1 is 39.09mm-39.19mm.

The PC board is fixed on the working table, and a layer of protective film is arranged between the PC board and the working table. When cutting, the cutting die is fed, so that the cutting part 3 of the blade 2 can contact the protective film, and the PC board can be cut and disconnected. The working platform drives the plate to move horizontally, and when the cutting die rotates, a chamfer is cut on the edge of the plate through the inclined part 4.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
