Embodiment Construction

[0010] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0011] See attached figure 1 , the present invention proposes a composite knife, including a knife handle 1 and a knife head, one end of the knife handle 1 is connected to one end of a support rod 2 by welding, and the right end surface is an arc-shaped convex surface, and the support rod 2 The left end surface is an arc-shaped concave surface matching with the arc-shaped convex surface, and the arc-shaped surface is welded together, which effectively avoids the phenomenon that the plane is not firmly bonded and is easy to break. Different from general V-shaped welding, the combination of curved surfaces is not conducive to the formation of stress concentration, and the welding effect is better.

[0012] The other end of the support rod 2 is connected to the cutter head. The cutte...

Abstract

The invention relates to a combination cutter. The combination cutter comprises a cutter handle and a cutter bit; one end of the cutter handle is connected to one end of a supporting rod by welding; the right end surface is an arc-shaped convex surface; the left end surface of the supporting rod is an arc-shaped concave surface adapting to the arc-shaped convex surface; the cutter bit is connected to the other end of the supporting rod; the cutter bit comprises a front cutting part, a rear cutting part and a bevel cutting part; one end of the bevel cutting part is at an taper angle of 102 degrees and is connected with the supporting rod, and the other end of the bevel cutting part is connected with one end of the rear cutting part; the front cutting part is connected with the rear cutting part through an arc-shaped cutting part; a grinding wheel is arranged in the middle part of the supporting rod; and the grinding wheel has the outer circle diameter the same as that of the rear cutting part. The combination cutter is able to perform milling and grinding once, so that the time is saved, and the efficiency is improved.

Description

technical field [0001] The invention relates to a composite knife, which belongs to the field of cutting tools. Background technique [0002] Existing milling and grinding generally use a grinding-milling compound machine tool or a tool holder, the overall structure is bulky, and the processing efficiency is low, which affects the processing cost and efficiency. The invention combines the milling cutter with the grinding wheel, and can complete the milling and grinding at one time during the axial feed, saving cost and time. Contents of the invention [0003] The purpose of the present invention is to provide a compound cutter, which combines the milling cutter with the grinding wheel, and can complete milling and grinding at one time when feeding in the axial direction, saving time and improving efficiency. [0004] In order to achieve the above object, the present invention provides a compound knife, including a knife handle and a knife head, one end of the knife ha...
