Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment, the present invention will be further described:

[0013] Such as figure 1 As shown, the curve-forming milling cutter includes a cutter body 1 and a handle 2, the handle 2 is a clamping part, and a cutting part 3 is provided on the cutter body 1, and the cutting part 3 is composed of an even number of cutting edges 4. Edge 4 is a sheet-like structure with uniform thickness, and each of said cutting edges 4 has an equal axial deflection angle, which is 3°-10°; The blade base surface M0 is composed of two radially symmetrical and continuous curved edges A and B protruding from the base surface. The left end surface of the cutting edge 4 is connected to the blade base surface MO by a 45° inclined plane. The two edges and corners formed between the inclined surface and the end surface and the blade all transition smoothly with arc surfaces.

[0014] Such as figure 2 As shown, the line type of the curved edge...

Abstract

The invention discloses a curve-shaped forming milling cutter. The cutter is characterized by comprising a cutter body and a cutter handle, the cutter handle is a clamping part, a cutting part is arranged on the cutter body, the cutting part is composed of an even number of cutting edges, the cutting edges are of sheet structures with the same thickness, each cutting edge has the same axial deflection angle, and the angle ranges from 3 degrees to 10 degrees; and an edge part of each cutting edge is composed of an edge part base plane parallel to the axial direction of the cutter body and two radially symmetrical and continuous curved edges protruding out of the base plane, the left end faces of the cutting edges are connected with the edge part base planes through 45-degree inclined planes, and two corner angles formed between the inclined planes and the end faces and between the inclined planes and the edge parts are in smooth transition through arc surfaces. When the curve-shaped forming milling cutter is used for machining an automobile sliding block, one-time machining forming can be achieved, and a sliding cavity with a curve-shaped milling face is obtained; and the inner wall of the curve-shaped sliding cavity is not provided with sharp corner angles, so that the sliding block can be better accommodated to move.

Description

technical field [0001] The invention belongs to the field of machining cutters, in particular to a curve-forming milling cutter. Background technique [0002] Milling is becoming more and more important in the field of mechanical processing, and has gradually replaced other processing methods such as turning and drilling to a certain extent. Milling cutters used for auto parts processing, because of the special shape of the processing part, conventional milling cutters often cannot be processed at one time, so it is necessary to customize a special shape of the milling cutter. The slider is a mold component that can slide perpendicular to the mold opening and closing direction or at a certain angle to the mold opening and closing direction during the mold opening action. When the product structure makes the mold unable to demould normally without using the slider, the slider must be used. The material of the sliding cavity in the car slider has proper hardness and wear res...
