Problems solved by technology

[0010] However, in the scraping method disclosed in Patent Document 1, a forced cooling device that sprays coolant directly to the cutting edge of the die is required, so the device is complicated.
Patent Document 2 mainly discloses the blade edge shape of a scraping die for relatively soft metal wires such as copper and copper alloys from the viewpoint of tool wear, but it is not a structure for steel wire materials harder than copper and copper alloys.
In addition, no consideration is given to the smoothness of the cut surface after shaving
[0011] In the process of cutting and removing the surface layer of the wire rod with the above-mentioned scraping tool, chips may be generated on the edge of the scraping tool due to the influence of residual scale and surface unevenness
When a chip is formed on the edge of the blade, processing flaws (cutting flaws) remain on the surface of the wire rod, and the processing force (cutting force) acting on the edge of the blade increases, so tool wear progresses significantly, and there is a problem that tool life is shortened

Embodiment Construction

[0032] Below, according to the attached Figure 1 to Figure 7 One embodiment of the present invention will be described.

[0033] figure 1 It is an explanatory drawing which schematically shows the shaving process of the wire rod using the shaving tool of one embodiment. The steel wire material (hereinafter referred to as "wire material") 1 as the workpiece is usually arranged on the output side of the scraping tool 2 ( figure 1 under the action of traction generated by the winder (not shown) on the right side of the figure 2 The scraping tool 2 of the shape shown. The surface layer 1a of the wire rod 1 is cut over the entire circumference by the cutting edge 2a. Surface defects of the wire rod 1 are removed together with the chips 1b. Such as image 3 As shown, the cutting edge 2a of the scraping tool 2 for scraping the surface of the wire rod 1 is formed so that the rake angle α becomes a negative value in the range of -5° to -30°. In addition, the cutting edge 2af o...

Abstract

The invention provides a scraping tool. The cutting edge (2a) of the scraping tool (2) has a negative rake angle (α) and a flat surface (4) of appropriate length is formed on the relief surface (3). By forming the negative rake angle, even if the center of the scraping tool (2) deviates from the center of the wire (1), the cutting component force acts in a direction to return the wire (1) to the center of the scraping tool (2). In addition, the flat surface (4) reduces the roughness of the processed surface of the wire material surface generated by the cutting edge, thereby improving the smoothness and improving the surface quality, and suppressing chipping of the cutting edge and tool wear.

Description

technical field [0001] The present invention relates to a shaving tool for peeling (shaving) the surface of the wire used in the manufacturing process of the wire used for suspension bridge cables, springs, and the like. Background technique [0002] On the surface of the wire rod after the hot rolling process, especially the steel wire rod, there are many irregularities due to defects such as scale and rolling flaws remaining. In order to smooth the surface of such a wire rod and improve the quality of the surface, the surface layer of the wire rod is often removed by cutting off the entire circumference of the wire rod with a die-shaped scraping tool (for example, refer to Patent Documents 1 and 2).
