Abstract
The utility model relates to a multi-outline forming knife. The multi-outline forming knife comprises a knife handle, wherein one end of the knife handle is connected with a knife head, the outer circle diameter of the knife head is smaller than that of the knife handle, the knife head comprises a first side face cutting edge and a second side face cutting edge which are parallel to each other, and a first end face cutting edge and a second end face cutting edge parallel to each other are arranged on the right side of the first side face cutting edge and the right side of the second side face cutting edge respectively; the first side face cutting edge is connected with the knife handle through a slope cutting edge, the cone angle formed by the slope cutting edge is 92 degrees, and an arc cutting edge is arranged between the first side face cutting edge and the second side face cutting edge. The problem of repeated chamfering in the machining process is avoided through the arc cutting edge, multiple cutting faces are convenient to form in a one-off mode, production requirements are met, and cost is saved.
Description
Technical field
The utility model relates to a kind of how contoured cutter, belongs to machine tools field.
Background technology
Along with social development, cutter has had very large improvement in each side such as material structures, but traditional cutter still cannot process the cambered surface profile of strip, and need to rely on some auxiliary equipment or on Digit Control Machine Tool, cambered surface profile be processed.The utility model is by improving the profile of cutter own, removed employing auxiliary equipment from while carrying out curved face processing, possibly cannot meet the problem of the needs of product to operating personnel's the precision of having relatively high expectations, processing, and reduces processing cost.
Utility model content
The purpose of this utility model is to provide a kind of how contoured cutter, by by the irregular cutting edge of cutter head outline polishing multiple tracks, meets one-shot forming requirement.
For achieving the above object, the utility model provides a kind of how contoured cutter, comprise handle of a knife, described handle of a knife one end connects a cutter head, described cutter head outside diameter is less than the outside diameter of handle of a knife, and cutter head comprises the first side cut sword and the second side cut sword, described first and second side cut sword is parallel to each other, and is respectively equipped with the first face cutting edge and the second face cutting edge that are parallel to each other on the right side of above-mentioned side cut sword; Described the first side cut sword is connected by an inclined-plane cutting edge with handle of a knife, and the conical surface angle that described inclined-plane cutting edge forms is 92 °, between the first side cut sword and the second side cut sword, is provided with arc milling sword.Arc milling sword has been avoided in process the repeatedly problem of chamfering, and one-shot forming is convenient in multiple cutting faces, has met the needs of producing, cost-saving.
Further improvement of the utility model is: the R angular radius of described arc milling sword is 0.25mm, meets circular arc groove face general on existing market.
Further improvement of the utility model is: the overall length of described first and second side cut sword and arc milling sword is 10mm, extends cutter bulk life time.
The beneficial effects of the utility model are: compact conformation, and easy to process, one-shot forming, cost-saving.
Brief description of the drawings
Fig. 1 represents structural representation of the present utility model;
Fig. 2 represents the A place enlarged drawing of the utility model Fig. 1;
Drawing reference numeral: 1-handle of a knife, 2-the first side cut sword, 3-the second side cut sword, 4-the first face cutting edge, 5-the second face cutting edge, 6-inclined-plane cutting edge.
Detailed description of the invention
In order to deepen, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be described in further detail.
By reference to the accompanying drawings 1 with accompanying drawing 2, the utility model proposes a kind of how contoured cutter, comprise handle of a knife 1, described handle of a knife 1 one end connects a cutter head, described cutter head outside diameter is less than the outside diameter of handle of a knife 1, and cutter head comprises the first side cut sword 2 and the second side cut sword 3, described first and second side cut sword is parallel to each other, and is respectively equipped with the first face cutting edge 4 and the second face cutting edge 5 that are parallel to each other on the right side of above-mentioned side cut sword; Described the first side cut sword 2 is connected by an inclined-plane cutting edge 6 with handle of a knife 1, and the conical surface angle that described inclined-plane cutting edge 6 forms is 92 °, between the first side cut sword 2 and the second side cut sword 3, is provided with arc milling sword.The R angular radius of described arc milling sword is 0.25mm, and the overall length of described first and second side cut sword and arc milling sword is 10mm.
By cooperatively interacting of two face cutting edges, side cut sword and the inclined-plane cutting edge 6 that are parallel to each other, make cutter profile be applicable to processing request, can once curved profile be processed, overcome the defect that transmission machining cannot be processed curved profile, improve working (machining) efficiency and machining accuracy simultaneously, met the needs of mass production.Arc milling sword has been avoided in process the repeatedly problem of chamfering, is convenient to one-shot forming.
