Abstract
The utility model provides a miller inclined plane punching cutter. The miller inclined plane punching cutter comprises a two-blade keyway milling cutter, wherein the keyway milling cutter changes flat concave blades on the top end of a blade head into sharp angle blades, and the place where sharp angles intersect is a sharp corner. The miller inclined plane punching cutter has the advantages that based on the principle of drill bit, design is simple and clear, workpieces are not prone to deformation due to the fact that the cutter has different stress cutting points, and therefore under the premise of quality guarantee, production efficiency is enhanced dramatically and production cost is reduced.
Description
Technical field
The utility model relates to cutting element manufacturing technology field, especially relates to a kind of milling machine inclined-plane perforating cutting tool.
Background technology
Cotter mill cutter is a kind of machining tool for the processing keyway, be provided with two main cutting edges that are positioned at the milling cutter both sides and the first front cutting edge and the second front cutting edge that is positioned at the milling cutter front end on the cotter mill cutter, the first front cutting edge and the second front cutting edge on the cotter mill cutter all have cutting edge inclination θ.When milling, be distributed in two cutting force on the cutter tooth apart from forming couple, radial load is cancelled each other, so can time processing go out the keyway of the width identical with the cutter tactical diameter.In order directly to process the keyway of closed at both ends, the centre of gyration position of the general direct arrival milling cutter of end sword length of cotter mill cutter can directly pierce workpiece vertically in addition.
Adopt the method for special mold and punch ram to hole to various small-sized thin plates, the punching of light wall pipe inclined-plane in the prior art, because the method precision is inadequate and it is large so that workpiece very easily is out of shape to spend because of stamping press, working (machining) efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of easy and simple to handle, the milling machine inclined-plane perforating cutting tool that working (machining) efficiency is high.
The technical solution of the utility model is: a kind of milling machine inclined-plane perforating cutting tool, comprise two sword cotter mill cutters, and described cotter mill cutter is with the flat indent sword transformation of the way sharp angle sharp knife of sword crown end, and it is wedge angle that described sharp angle is handed over to locating.
Described cotter mill cutter is 169 °-171 ° with the angle of the sharp angle sharp knife that the flat indent sword of sword crown end is changed system into.
Advantage and the good effect that the utlity model has are: the utility model simplicity of design understands, take the drill bit principle as foundation, but its different stressed cutting point is arranged, so that workpiece is not yielding, under the prerequisite of ensuring the quality of products, greatly improved production efficiency, reduced production costs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, cotter mill cutter, 2, sharp angle, 3, workpiece.
The specific embodiment
As shown in Figure 1, a kind of milling machine of the utility model inclined-plane perforating cutting tool comprises two sword cotter mill cutters 1, and described cotter mill cutter 1 is 169 °-171 ° with the angle of the sharp angle sharp knife that the flat indent sword of sword crown end is changed system into, and it is wedge angle that sharp angle 2 is handed over to locating.Its Main Function is the effect of playing fulcrum when the sharp angle point is by workpiece 3 at work, to pushing the metal mode everywhere aside, avoids cutter to tremble when strong assurance main cutting edge cuts, thereby guarantees that workpiece 3 orifice parts can not break, and cutter can be partial to cutting.
The utility model simplicity of design understands take the drill bit principle as foundation, but its different stressed cutting point is arranged, so that workpiece is not yielding, has greatly improved production efficiency under the prerequisite of ensuring the quality of products, and reduces production costs.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
Claims (2)
1. milling machine inclined-plane perforating cutting tool is characterized in that: comprise two sword cotter mill cutters (1), described cotter mill cutter (1) is with the flat indent sword transformation of the way sharp angle sharp knife of sword crown end, and it is wedge angle that described sharp angle (2) is handed over to locating.
2. a kind of milling machine according to claim 1 inclined-plane perforating cutting tool, it is characterized in that: described cotter mill cutter (1) is 169 °-171 ° with the angle of the sharp angle sharp knife that the flat indent sword of sword crown end is changed system into.
