Description

Tool

本設計之物品，係一種金屬切削用的刀具。 The item of this design is a tool for metal cutting.

本設計之設計特點在於，該刀具具有一螺旋刃長部位及一前端刀刃部位，該螺旋刀刃部位具有大小寬幅的溝槽，其溝槽分為兩單溝槽及兩雙溝槽設計，且溝槽底部形狀似圓弧狀。 The design feature of the design is that the tool has a spiral blade length portion and a front end blade portion, the spiral blade portion has a wide and wide groove, and the groove is divided into two single grooves and two double groove designs, and The bottom of the groove is shaped like an arc.

該螺旋刃長部位又在刃長做四個不等導程的螺旋角設計，分為第一刃長螺旋角設計為固定的螺旋角(40度)，第二刃長的螺旋角設計為變動螺旋導程(角度由38度以刃長遞增至41度)，第三刃長的螺旋角設計為分段固定螺旋角(分38度和41度為交錯變換)，第四刃長的螺旋角設計為變動螺旋角(角度由41度以刃長遞減至38度)。 The long edge portion of the spiral blade is designed to have four unequal lead spiral angles at the blade length, and is divided into a first blade long helix angle designed as a fixed helix angle (40 degrees), and a second blade length helix angle is designed to be changed. Spiral lead (angle is increased from 38 degrees to 41 degrees), the helix angle of the third blade is designed as a segmented fixed helix angle (interleaved by 38 degrees and 41 degrees), and the helix angle of the fourth blade length Designed to vary the helix angle (angle is reduced from 41 degrees to 38 degrees).

該前端刀刃段由四個刀刃單元為環繞360度設置，由前視圖觀之，其中兩個長刃單元相連概成概成S型，另外兩個短刀刃單元概成矩形各自獨立，該端面又有四個大小溝槽，且溝槽底部形狀似圓弧狀，其中大溝槽有兩個不同軸向角度形成，另外小溝槽由一個軸向角形成。 The front cutting edge segment is arranged by four blade units around 360 degrees, and is viewed from a front view. Two long blade units are connected to form an S-shaped shape, and the other two short-blade units are formed into rectangular shapes, and the end faces are respectively independent. There are four large and small grooves, and the bottom of the groove is shaped like an arc, wherein the large groove is formed by two different axial angles, and the small groove is formed by an axial angle.

而第一個端切面和第二個端切面形成其周向夾角為A角度、第三個端切面和第四個端切面形成其周向夾角為B角度，其為第二個端切面和第三個端切面形成其周向夾角為C角度，第四個端切面和第一個端切面形成其周向夾角為D角度，其設計為A角度等於B角度、C角度等為D角度，而A角度不等於C角度，各角度加總為360度，形成為不等份割形狀。 The first end face and the second end face form a circumferential angle of the A angle, the third end face and the fourth end face form a circumferential angle B angle, which is the second end The cut surface and the third end cut surface form an angle C of the circumferential direction, and the fourth end cut surface and the first end cut surface form a circumferential angle of the D angle, and the design is such that the A angle is equal to the B angle, the C angle, and the like is D. Angle, and A angle is not equal to C angle, and each angle is added to 360 degrees, forming an unequal shape.
