Abstract
The utility model relates to a special cutter for cutting a concave groove on an inner hole of a nut in one side direction or a longitudinal direction. The utility model is characterized in that the body of the utility model is an anomalous cylindrical body, wherein, the body of the utility model comprises a cutting cylindrical body part and a non-cutting cylindrical body part; the body of the utility model is provided with a front cutter face 11 and two adjacent main rear cutter faces, the front cutter face 11 is positioned on the bottom surface of the non-cutting cylindrical body, and the two adjacent main rear cutter faces are positioned on the non-cutting cylindrical body part; the intersecting lines of the front cutter face 11 and the two adjacent main rear cutter faces are horizontal cutters; a cylindrical body structure which is composed of the two main rear cutter faces and the horizontal cutters is exactly matched with the side concave groove of the inner hole of a cut nut. The utility model solves the problems of complicated processing, high cost and little opportunity in realizing industrialized production; besides, the problems are generated by the operation of cutting a star-shaped concave groove on the inner hole of a nut towards a side direction or a longitudinal direction, and the bottom of the concave groove is provided with a circular arc cylindrical surface; the utility model has the advantages of simple fabrication, favorable precision and high rate of finished products; fabrication cost and investment cost are reduced.
Description
The utility model belongs to a kind of metal cutting tool, and particularly a kind of can be concave arc cylinder inwards at nut inner hole side straight-cut bottom land
The dedicated tool of connected in star.
The processing of inner hole key slot in the prior art, slotting tool on the general employing slotting machine carries out slotting processing, the slotting tool of present industrial usefulness can only be used for the processing of the strong groove of general common shape, such as triangle, rectangle, shape such as square, and also exist slotting tool fragile, the not high shortcoming of the precision of processing.If but be threaded into direction bottom land from shallow to deep for the special shape of concave arc cylinder inwards to open an edge in the nut inner hole side
The processing of connected in star, slotting tool of the prior art can't be processed, and realize this special shape
The processing of connected in star just must be adopted methods such as line cutting, electric pulse cutting and plasma cutting, so not only the processing cost of each nut up to 3 yuan about, the client can't bear, and process velocity is very slow, can't realize large quantities of suitability for industrialized production of putting.
The purpose of this utility model is to overcome shortcoming of the prior art, designs a kind ofly can vertically open an edge in the nut inner hole side to be threaded into direction bottom land from shallow to deep be the concave arc cylinder
The dedicated tool of connected in star.
Shaping by stock removal dedicated tool of the present utility model mainly comprises handle of a knife and cutter hub, it is characterized in that cutter hub is the structure of special-shaped cylinder, cutter hub comprises that cutting cylinder part is used for increasing the non-cutting cylinder part of cutter hub intensity with being connected as a single entity with it, and the cylinder bottom surface of cutter hub is a rake face; Two adjacent cylinders of the cutting cylinder part of cutter hub are respectively two main back knife faces of cutter hub, one of them main back knife face is designed to cambered outwards dome arc column face, the straight prismatic surface or the cambered outwards slightly circular arc cylinder of another main back knife face, the intersection of two main back knife faces is a chisel edge, two cutting cylinder structures of leading back knife face and chisel edge formation just in time match with the groove that the nut inner hole side will be cut, the main back knife face of dome arc column face just in time with along the bottom land that is threaded into direction fluted column face from shallow to deep matches, the intersection of the main back knife face of rake face and cambered outwards dome arc column face is the circular curve cutting edge, the intersection of rake face and another main back knife face is another cutting edge, the circular curve cutting edge, the intersection point of cutting edge and three swords of chisel edge is a point of a knife; Non-cutting cylinder part is not essential, changeable, does not hinder the irregular prism of screw thread as long as be designed to be convenient to insert nut inner hole or the cylinder of other level and smooth circular arc cylinder just can.
Shaping by stock removal dedicated tool of the present utility model only need be installed in and just can realize being used for processing nut inner hole side edge on punch press or the slotting machine and be threaded into direction concave arc cylinder bottom land from shallow to deep
Connected in star; Processing is promptly convenient fast again, the yield rate height; Not only can cut down finished cost greatly and cost of investment, and can realize mass industrialized production.This cutter also has characteristics such as intensity is good, not fragile, long service life in addition.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the perspective view of a kind of embodiment of the utility model.
Fig. 2 is the cutaway view that prolongs Figure 1A-A direction.
Generalized section when Fig. 3 is the utility model embodiment dedicated tool cutting nut.
Among the figure: 1. handle of a knife 2. cutter hubs 3. cut cylinder parts 4. non-cutting cylinder part 5. main back knife faces 6. main back knife face 7. chisel edges 8. circular curve cutting edges 9. points of a knife 10. cutting edges 11. rake face 12.V type grooves
As shown in the figure, dedicated tool of the present utility model mainly comprises handle of a knife 1 and cutter hub 2, it is characterized in that cutter hub 2 comprises cutter body part 3 and is connected as a single entity with it is used for strengthening the non-cutting cylinder part 4 of cutter hub intensity, this two all divides and constitutes the Special-Shaped Column body structure, cutter hub has a rake face 11 and two main back knife faces (5,6), the cylinder bottom surface of cutter hub is a rake face 11, the main back knife face 6 of the left surface of the chisel edge 7 of cutting cylinder part is outside dome arc column face, the main back knife face 6 of the left surface of chisel edge 7 is straight prismatic surface, two main back knife faces (5,6) and chisel edge 7 just in time constitute evagination
The shape cylinder is cutting cylinder part 3, is used for cutting the nut inner hole side longitudinally
Connected in star; The cylinder that the main back knife face 6 and the non-cutting cylinder of cambered outwards circular arc cylinder all divide excessively forms level and smooth cambered outwards circular arc cylinder naturally; The main back knife face 5 of straight cylinder forms v-depression 12 with the cylinder of adjacent non-cutting cylinder part, and promptly the right flank of chisel edge is v-depression 12 (as shown in Figure 1).Rake face 11 is a circular curve cutting edge 8 with the intersection of main back knife face 6, and rake face 11 is a linear cutting edge 10 with the intersection of main back knife face 5; The intersection point of circular curve cutting edge 8, linear cutting edge 10 and 7 three swords of chisel edge is a point of a knife 9.The angle γ of rake face and basal plane is generally 7 °-15 °.
In addition according to the difference of nut shape number, the shape of the utility model dedicated tool is number also different.When the nut model was big, cutter was corresponding also big, and when nut model hour, cutter is also corresponding scaled thereupon.
