Abstract
The utility model relates to a machining tool in machine work, in particular to a formed cutter which comprises a cylindrical main cutter body, a front-end blade and a plurality of spiral screw blades, wherein the cylindrical main cutter body rotates by taking an axis as a rotation axis; the front-end blade is arranged on the main cutter body; the spiral screw blades are arranged at the periphery of the main cutter body in a ring-shaped manner at the side part of the front end of the main cutter body; a chip removal groove is formed between every two adjacent screw blades; the front-end blade arranged on the main cutter body comprises a first cutting edge with the axis as a starting end, a second cutting edge connected with the terminal of the first cutting edge, a third cutting edge connected with the terminal of the second cutting edge, and a fourth cutting edge connected with the terminal of the third cutting edge; and the terminal of the fourth cutting edge is provided with an arc cutting edge. The formed cutter completes corner machining on a workpiece simultaneously when milling the workpiece, so that the part of the workpiece needing to be machined is molded by one-step operation, thus improving the production efficiency; and the one-step molding reduces the damage on the workpiece in secondary machining, thus reducing the production cost.
Description
Technical field
The utility model relates to the process tool in a kind of machining, is specifically related to a kind of profile milling cutter.
Background technology
When the processing lever assembly, need carry out the processing of corners and fillets to workpiece, simultaneously the burr that produces when removing processing work need carry out secondary or repeatedly processing to processing work, when workpiece is carried out chamfering or fillet usually, the angle that needs tool changing or adjustment cutter, process often, the operation more complicated, and the clamping cutter is cumbersome, such processing was both lost time, and operating efficiency is low again.
The utility model content
At the problems referred to above, the purpose of this utility model provides a kind of profile milling cutter of finishing the workpiece fillet in the processing work process simultaneously.
Profile milling cutter, comprise with the axis being the cylindric cutter body of rotating shaft rotation, the multiple tracks that is arranged on the front edge of cutter body and cutter body front end sidepiece is the helical edges of shape annular array around cutter body in the shape of a spiral, form a chip removal groove between the per two adjacent helical edges, the described cutter body front edge that is arranged on comprises with described axis being first cutting edge at top, second cutting edge that is connected with the first cutting edge terminal, the 3rd cutting edge that is connected with the second cutting edge terminal, with the 4th cutting edge that the 3rd cutting edge terminal is connected, the terminal of described the 4th cutting edge is provided with the circular arc cutting edge.
Further, described the 3rd cutting edge and described the 4th cutting edge intersection are the arc transition sword, the circular arc cutlery of its transition has radius, the radius of this arc transition sword can be provided with according to the fillet of workpiece needs, the described circular arc cutting edge that is arranged on the 4th cutting edge terminal, this circular arc cutting edge one end is connected with described cutter body front end sidepiece, and the other end of circular arc cutting edge is connected with the terminal of the 4th cutting edge.
Described first cutting edge parallels with the cross section of described cutter body, the cross section of described second cutting edge and described cutter body forms an angle α, the cross section of described the 3rd cutting edge and described cutter body forms an angle β, and the cross section of described the 4th cutting edge and described cutter body forms an angle γ.Angle between described first, second, third, fourth blade and the cutter body cross section can be provided with according to the needs of workpiece.
Described front edge can be arranged to single or a plurality of, is evenly distributed in the end of cutter body.
Carbon modulation steel material was made during described cutter body adopted.
Described front edge and helical edges all adopt the wolfram steel material to be made.
Adopt such scheme, the utility model is when the milling workpiece, finished fillet processing simultaneously to workpiece, make the position one-shot forming that needs processing work, can guarantee simultaneously the uniformity of workpiece to be machined size, improved production efficiency, added the damage that causes workpiece man-hour once more owing to one-shot forming has reduced, thereby reduce production costs.
