Abstract
The invention relates to a T-shaped cutter. The T-shaped cutter comprises a cutter handle and a cutter head, wherein the cutter handle and the cutter head are connected through a cone-shaped body; a cutter head cylinder is arranged between the cutter head and the cone-shaped body; axial width of the cutter head cylinder is greater than that of the cutter head; the cutter head is gyroscope-shaped; a front end face of the cutter head is a main cutting face; a plurality of arc-shaped faces with different semi-diameters and directions are formed at the periphery of the middle of the cutter head; the arc-shaped faces are combined to form a secondary cutting face of the cutter head, so that the outer contour of the cutter head is an irregular wavy curved surface. Due to the cone-shaped body, a larger avoiding space is provided, so that the contact between a cutter handle part and workpieces in a cutting process can be avoided. Due to the wavy secondary cutting face, the problem of chamfering for multiple times in a processing process can be avoided, so that one-step molding is facilitated.
Description
Technical field
The present invention relates to a kind of T-shaped cutter, be specifically related to a kind of forming T-shaped cutter, belong to machine tools field.
Background technology
T-shaped cutter is processing T type groove, lateral grooves processing perfectly, at high temperature normally maintains cutting ability.And in process, cutter, due to the unicity of contour surface, needs again to carry out fine finishining and chamfering after processing, increase processing step, also waste manpower and materials, be difficult to guarantee one-shot forming.
Summary of the invention
The object of the present invention is to provide a kind of T-shaped cutter, by cutter head outline having been set up to irregular secondary cutting face, make cutter meet more complicated groove cutting, practicality is stronger.
For achieving the above object, the invention provides a kind of T-shaped cutter, comprise handle of a knife and cutter head, between described handle of a knife and cutter head, be connected with a bullet; Between described cutter head and bullet, be provided with cutter head cylinder, the axial width of described cutter head cylinder is greater than cutter head; Described cutter head is gyroscope-like, the front end face of cutter head is main cutting face, is circumferentially with at cutter head middle part the arc surface that some roads radius is not identical with direction, the secondary cutting face of described arc surface composition cutter head, make the outline of cutter head be irregular wave shape curved surface, the height of described cutter head is 11mm.Bullet provides the larger bit space that allows, and avoids handle of a knife position in working angles to touch workpiece.The repeatedly problem of chamfering has been avoided in process in corrugated secondary cutting face, is convenient to one-shot forming, meets the limitation of conventional tool processing, has improved machining accuracy and working (machining) efficiency, has met the needs of producing.
Described cutter head middle part is circumferentially also provided with the identical circular arc of three road radiuses, and described circular arc one is identical with circular arc three bending directions, and described circular arc two is tangent with circular arc three.Identical radius has guaranteed the uniformity of secondary cutting face transition, and circular arc two and the tangent effective formation special surface of circular arc three, avoid chamfering step, improves precision simultaneously.
Further improvement of the present invention is: the angle of the conical surface of described bullet is 50 °, providing the effect of stepping down simultaneously, has guaranteed enough large moment of torsion, puts only tool damage and even ruptures.
The invention has the beneficial effects as follows: compact conformation, easy to process, one-shot forming, cost-saving.

Fig. 2 represents the A place enlarged drawing of Fig. 1 of the present invention;
Fig. 3 represents fundamental diagram of the present invention;
Drawing reference numeral: 1-handle of a knife, 2-cutter head, 3-bullet, 4-cutter head cylinder, 5-circular arc one, 6-circular arc two, 7-circular arc three, 8-workpiece.
The specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail.
By reference to the accompanying drawings 1 with accompanying drawing 2, the present invention proposes a kind of T-shaped cutter, comprise handle of a knife 1 and cutter head 2, between described handle of a knife 1 and cutter head 2, be connected with a bullet 3, the angle of the conical surface of described bullet 3 is 50 °, bullet 3 provides the larger bit space that allows, and avoids handle of a knife 2 in working angles to touch workpiece 8.Between described cutter head 2 and bullet 3, be provided with cutter head cylinder 4, the axial width of described cutter head cylinder 4 is greater than cutter head 2, and putting only cutter head cylinder 4 affects cutter head cutting, leaves larger space for secondary cutting face, meets the requirement of groove cutting.
Described cutter head 2 is gyroscope-like, be highly 11mm, the front end face of cutter head 2 is main cutting face, is circumferentially also provided with at cutter head 2 middle parts the arc surface that some roads radius is not identical with direction, the secondary cutting face of described arc surface composition cutter head 2, makes the outline of cutter head 2 be irregular wave shape curved surface.Described cutter head 2 middle parts are circumferentially with the identical circular arc of three road radiuses, and radius is 0.3mm, and described circular arc 1 is identical with circular arc 37 bending directions, and described circular arc 26 is tangent with circular arc 37, Transitional cut face in forming.
Referring to accompanying drawing 3, in the time that cutter is worked, bullet 3 plays the effect of stepping down, secondary cutting face is prior to cutter head cylinder 4 cutting workpieces 8, the repeatedly problem of chamfering has been avoided in process in corrugated secondary cutting face, is convenient to one-shot forming, meets the limitation of conventional tool processing, improve machining accuracy and working (machining) efficiency, met the needs of producing.Profile tolerance is followed anterior angle and is changed and change, and easy to process, wear rate is little.
