Abstract
The utility model discloses a hand-operated knife, which comprises a knife handle and a knife body, wherein the knife body consists of a knife body and an alloy blade, slot bodies are respectively arranged on the front and the rear sides of the knife body, and are symmetrically arranged along an axial line of the knife body, the cross sections of the slot bodies are of an connected structure of a straight line and a circle arc, the side surfaces of the slot bodies are vertical to a plane which is provided with the slot bodies, and the alloy blade is welded on the side surfaces of the slot bodies. The hand-operated knife has the advantages of excellent chip removal effect, high cutting precision, steady quality and more durability.
Description
Technical field
The utility model relates to a kind of cutter, more particularly, relates in particular to one and takes out hand cutter.
Background technology
Take out hand cutter generally for processing the handle hole of cabinet door, use amount is generally larger.As shown in Figures 2 and 3, tradition is taken out hand cutter and is made up of handle of a knife 10 and cutter hub 20, cutter hub 20 is made up of cutter hub body 30 and alloy blade 40 again, cutter hub body 3 both sides are respectively equipped with mounting groove 50, two mounting grooves 50 are along cutter hub central axis symmetry, alloy blade 40 is fixed in mounting groove 50, alloy blade 40 bottoms are consistent with mounting groove 50 bottoms, alloy blade 40 is welded in mounting groove 50 sides, traditional processing mode that adopts oblique line while taking out the mounting groove 50 of hand cutter on milling processing cutter hub body 30, mounting groove 50 cell bodies surfaces extend to cutter head top for straight line, only has 0.1mm at cutter hub body 30 front end rigid body thickness, the matrix of two blade solders side connects by the steel body thickness of 0.1mm, therefore, in the use procedure of cutter, tearing often easily appears in cutter front end, there is distortion in tipping or cutter hub.Moreover, must guarantee that according to the structure of cutter hub 20 interface point of front end two-edged can not be gapped, can not be by the 30 front ends thickenings of cutter hub body, otherwise can affect the chip removal effect of cutter.Thus, traditional take out hand cutter and can not meet processing instructions for use, need to improve structure of the cutter body and improve cutter quality.
Utility model content
The purpose of this utility model is to provide that a kind of chip removal is effective, cutting precision is high, steady quality, the more durable hand cutter of taking out.
The technical solution adopted in the utility model is as follows:
One is taken out hand cutter, comprise handle of a knife and cutter hub, described cutter hub is made up of cutter hub body and alloy blade, cutter hub body both sides are respectively equipped with mounting groove, described alloy blade is fixed in mounting groove, and the bottom surface of described mounting groove is made up of transition face, bottom surface and joint face, and the bottom surface basic side of wherein said both sides mounting groove is parallel and symmetrical along axis, described joint face is U-shaped curved surface, and the bottom surface front end on both sides is by joint face smooth connection.
Further, described cutter hub body nose thickness is 2～3mm.
Further, described alloy blade bottom is consistent with the cell body surface of described mounting groove, and alloy blade seamless welding is in mounting groove side.
Compared with prior art, the beneficial effect the utlity model has is:
The utility model adds the angle of fluting in man-hour to be improved by tradition being taken out to the milling of hand cutter cell body, and cutter is added and cuts into the structure that straight line is connected with circular arc man-hour in milling, and such cell body tangent plane radian designs, and is more conducive to the chip removal effect of cutter hub; Because cutter hub front end junction keeps original contour structures, and the cell body tangent plane of cutter hub has changed into after straight line and circular arc syndeton, the 0.1mm that cutter hub body front end rigid body thickness is taken out hand cutter by tradition has become 2～3mm, because the solder side rigid body thickness that connects two alloy blades increases, when cutting, cutter hub holding capacity becomes large, therefore be not easy to occur skew or distortion, the cutting precision of cutter hub is higher; The rectilinear form of conventional alloys blade bottom is changed into consistent with the cell body shape after milling processing, the handing-over mouth of alloy blade and the seamless welding of cell body side are guaranteed, cutter hub is not easy to produce and tears and tipping like this, the quality of cutter hub is more stable, the hand cutter of taking out after improvement more meets processing needs, more durable.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the structural representation of conventional tool;
Fig. 3 is the cutter head schematic cross-section of conventional tool;
Fig. 4 is structural representation of the present utility model;
Fig. 5 is cutter head schematic cross-section of the present utility model.
The specific embodiment
Below in conjunction with the specific embodiment, the technical solution of the utility model is described in further detail, but does not form any restriction of the present utility model.
With reference to Fig. 1, described in Fig. 4 and Fig. 5, one of the present utility model is taken out hand cutter, comprise handle of a knife 1 and cutter hub 2, cutter hub 2 is made up of cutter hub body 3 and alloy blade 4, cutter hub body 3 both sides are respectively equipped with mounting groove 5, alloy blade 4 is fixed in mounting groove 5, the bottom surface of mounting groove 5 is by transition face 6, bottom surface 7 and joint face 8 form, wherein bottom surface 7 basic sides of both sides mounting groove 5 are parallel and symmetrical along axis, joint face 8 is U-shaped curved surface, bottom surface 7 front ends on both sides are by joint face 8 smooth connections, such mounting groove 5 cell body radian designs, more be conducive to the chip removal effect of cutter hub 2.
The oblique line shape that hand cutter is taken out to by tradition in alloy blade 4 bottoms become consistent with the cell body surface of mounting groove 5 after, be welded to cell body 5 sides, guarantee the handing-over mouth of alloy blade 4 and the seamless welding of mounting groove 5 sides, cutter hub 2 is not easy to produce and tears and tipping like this, the quality of cutter hub 2 is more stable, the hand cutter of taking out after improvement more meets processing needs, more durable, and the product order volume after improvement has obvious increase.
In the time considering to improve this cutter, also can increase by heat treated mode intensity and the rigidity of cutter, but the cutter hub quality increasing after Technology for Heating Processing only promotes 10% left and right, DeGrain.Therefore, can only consider from the structure aspects of improving cutter hub 2, draw through practice, a kind of hand cutter of taking out of the present utility model is by taking out the change of hand cutter cell body milling when processing angle to tradition, cutter hub rigidity increases substantially, and in the manufacturing procedure of taking out hand cutter, reduced original heat treatment step, and the rigidity of cutter hub also can meet instructions for use, and the hand cutter product of taking out after improvement is not received the complaint of client to cutter quality aspect again.
The concrete service condition of present embodiment is as follows:
Use before this kind of cutter, Cutting tool installation manner, on gong machine, is determined to, after installation firmly, start, just can carry out perforate according to the cabinet catch position that requires of design specification.
The foregoing is only preferred embodiment of the present utility model, all any modifications of doing within the scope of spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
