Abstract

The utility model discloses a triangular pyramid lettering knife. The triangular pyramid lettering knife comprises a knife bar (1) and a knife head (2), wherein the knife head (2) is a triangular pyramid, three edges (3) of the triangular pyramid are three cutting blades of the lettering knife, a knife point which is the intersection of the three cutting blades is arranged on a central axis of the knife bar (1). When lettering, the triangular pyramid lettering knife has the advantages of being capable of keeping the dynamic balance of the knife during the high speed rotating of a main shaft of the knife bar, keeping good stability, having longer service life and processing more efficiently.

Description

The triangular pyramid carver

Technical field

The utility model belongs to the cutter field, and being specifically related to is a kind of carver.

Background technology

Carver is a kind of machining tool, being used for machinery carves characters, during work, spindle motor of machine tool drive carver vertically High Rotation Speed as main motion, the X of lathe, Y, Z axis move as synkinesia, the carver blade is cut part, form the depression track, this depression track can be free-throw line bar, numeral, literal, pattern etc.

The carver that uses at present mostly is small diameter solid cutter, a kind of carver is disclosed such as patent documentation CN201120043025.1, it comprises cutter body, be provided with cutter head at described cutter body, cutter head is half cone-shaped, wherein the tool bit diameter minimum can be 0.02mm, near a point, can satisfy the Li Jiao requirement of carving characters, but this carver is because cutter head is half cone-shaped, and its cutting edge only has one, when the main shaft High Rotation Speed cuts, the centrifugal force that the amount of unbalance that tool bit part exists produces will apply cyclic load to critical components such as main shaft bearings, thereby cause vibration, do not meet high-speed cutting processing to the requirement for dynamic balance of rotary cutter, equal Shortcomings of stationarity and life-span.

Summary of the invention

The purpose of this utility model is to provide a kind of triangular pyramid carver, by increasing cutting edge, solves carver keeps cutter when high-speed cutting dynamic balancing, strengthens the stability of cutter, increases the service life, and improves working (machining) efficiency.

The triangular pyramid carver of realizing the utility model purpose comprises knife bar and cutter head, and wherein cutter head is positive triangular taper, and three seamed edges of triangular pyramid are three cutting edges of carver, and the point of a knife point that three cutting edges cross is positioned on the central axis of described knife bar.

Further, three of described carver cutting edges evenly distribute.

Further, cutter head and knife bar are structure as a whole.

Triangular pyramid carver cutting edge of the present utility model is three, when carving characters, and the dynamic balancing that can keep cutter in the knife bar main shaft High Rotation Speed, better than semicircle cone carver stability, and also the life-span is longer, and working (machining) efficiency is also higher.

Description of drawings

Fig. 1 is carver structural representation of the present utility model;

Fig. 2 is the structural representation at another visual angle of carver of the present utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

As illustrated in fig. 1 and 2, the triangular pyramid carver in the present embodiment comprises knife bar 1 and cutter head 2, and cutter head 2 is positioned at knife bar 1 one ends, and both consist of preferred one.

Knife bar 1 is generally cylinder type.Cutter head 2 is the triangular taper, and three seamed edges of triangular pyramid are the summit (being the point of a knife point) that crosses of 3, three cutting edges 3 of three cutting edges of carver and the axis coinciding of knife bar 1, and the point of a knife point is positioned on the central axis of knife bar 1.

Triangular taper in the present embodiment is preferably positive triangular pyramid, and three cutting edges are evenly distributed.

Claims

1. triangular pyramid carver, comprise knife bar (1) and cutter head (2), it is characterized in that, described cutter head (2) is the triangular taper, three seamed edges (3) of this triangular pyramid are three cutting edges of carver, and the point of a knife point that these three cutting edges cross is positioned on the central axis of described knife bar (1).

2. a kind of triangular pyramid carver according to claim 1 is characterized in that, described triangular pyramid is positive triangular pyramid, and described three cutting edges evenly distribute.

3. a kind of triangular pyramid carver according to claim 1 and 2 is characterized in that, described cutter head (2) and knife bar (1) are structure as a whole.
