Abstract

The utility model belongs to the technical field of processing device accessories, and relates to a cutter, in particular to a pen-making cutter. The pen-making cutter comprises a cutter rest (1) and blades (3), wherein the blades (3) are fixed on the cutter rest (1) through clamping devices (2); a cutter groove (4) is formed in the front end of the cutter rest (1); and a shaft hole (5) is formed in the rear end of the cutter rest (1); the cutter (1) is matched with a shaft on a pen-making device through the shaft hole (5), and the cutter rest (1) is driven to rotate. According to the pen-making cutter, the blades are clamped on the cutter rest in a mechanical clamping manner; the blades can be made of PCD (poly crystal diamond) compacts or high-hardness alloys, the service life of the cutter is greatly prolonged, the problem that large-sized blades made of the PCD compacts or the high-hardness alloys are difficult to weld is effectively solved, the operation is simple and convenient, the cutter rest can be used repeatedly, and the manufacturing cost can be greatly reduced; and the cutter has good application prospects in the technical filed of the processing device accessories.

Description

A kind of graver tool processed

Technical field

The utility model belongs to process equipment accessory technical field, relates to a kind of cutter, relates in particular to a kind of graver tool processed.

Background technology

At present, make the cutter of Wood pencil, eyebrow pencil, generally all use the little dise knife of high-speed steel, this cutter life is very short, just needs half an hour to repair, also there is fraction to use carbide alloy, but this cutter can only use the lower carbide alloy of hardness, if use the carbide alloy of high rigidity, often causes the problem that is difficult to weld, and use the lower carbide alloy of hardness, generally also be no more than 6 hours service life.

Summary of the invention

The purpose of this utility model is to overcome graver tool weak point in service life processed in the prior art, and be difficult to defectives such as welding between blade and the knife rest, a kind of graver tool processed is provided, the mode that adopts the mechanical type clamping with moulding blade clamping on knife rest, can effectively solve Welding Problems, blade uses PCD composite polycrystal-diamond or high rigidity carbide alloy, and improved its service life greatly, and knife rest also can reuse the saving cost.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:

A kind of graver tool processed comprises knife rest and blade, and blade is fixed on the knife rest by clamping device.Graver tool processed of the present utility model, knife rest separates with blade, mode by the mechanical type clamping with the blade clamping on knife rest, blade can be selected PCD composite polycrystal-diamond or high rigidity carbide alloy for use, lengthen the service life of cutter greatly, can reach 240 hours respectively and 10～20 hours.Compare with the graver tool processed of prior art, do not need blade is welded on the knife rest, can efficiently solve the problem that large scale PCD composite polycrystal-diamond or high rigidity carbide alloy are difficult to weld, simple to operation.And knife rest and blade separate machined, improving yields, knife rest can also be reused, and can reduce manufacturing cost greatly.

As preferably, clamping device is screw.

As preferably, screw has a plurality of, along becoming wire to arrange on the blade direction.Can reinforce knife rest to the clamping dynamics of blade.

As preferably, the knife rest front end is provided with the cutter groove.Blade is placed in the cutter groove, clamps with screw again, and blade is played good position-limiting action.

As preferably, the knife rest rear end is provided with axis hole, and knife rest matches with axle on the system equipment by axis hole, drives blade holder turns.

The shape of blade can be adapted to the pencil shape of cross section for circle, regular hexagon (as shown in Figure 1, 2) and be adapted to pencil pen core (as shown in Figure 3).

The utility model discloses a kind of graver tool processed, knife rest separates with blade, mode by the mechanical type clamping with the blade clamping on knife rest, blade can be selected PCD composite polycrystal-diamond or high rigidity carbide alloy for use, lengthen the service life of cutter greatly, can reach 240 hours respectively and 10～20 hours.Compare with the graver tool processed of prior art, do not need blade is welded on the knife rest, can efficiently solve the problem that large scale PCD composite polycrystal-diamond or high rigidity carbide alloy are difficult to weld, simple to operation.And knife rest and blade separate machined, improving yields, knife rest can also be reused, and can reduce manufacturing cost greatly.In process equipment accessory technical field, good prospects for application is arranged.
