Hand carving knife

Abstract

The invention discloses a hand carving knife, and belongs to the field of machining tools for die-cutting knife rollers. The hand carving knife comprises a knife handle and a knife body mounted on theknife handle. A blade section used for sharpening an upper cutting edge of a die-cutting knife roller is arranged at the end, away from the knife handle, of the knife body. The end face, away from the knife handle, of the blade section of is a blade face. An included angle between the blade face and the plane perpendicular to the length direction of the blade section is 4-8 degrees. The inclination direction of the blade face is the same as that of the side face of the upper cutting edge of the die-casting knife roller. The hand carving knife has the effect that the operation accuracy duringsharpening polishing of the cutting edge can be easily controlled, and thus, sharpening is convenient.

Description

technical field [0001] The invention relates to the field of die cutter roller processing tools, in particular to a manual engraving knife. Background technique [0002] The die-cutting knife roll is a high-efficiency die-cutting tool that processes and shapes the cutting edge on a circular shaft and replaces flat-pressing and punching. It is mainly used in printing, mobile phone accessories manufacturing, paper packaging, non-woven fabrics and other industries. [0003] Different product processing, the designed edge shape is not the same. In the prior art, if the specification attached figure 1 with 2 As shown, the cutting edge 51 on the die cutter roller 5 is usually milled out by a milling machine, and then the cutting edge 51 is sharpened (even if the edge width of the cutting edge 51 is infinitely close to 0) before the product can be processed. Make a cut. However, affected by the processing accuracy of traditional milling machines, the edge width of cutting edge ...

Problems solved by technology

As attached to the manual figure 2 As shown, the cutter head 6 of the existing manual carving knife is at a right angle, and when it is stretched into the side wall of the cutting edge 51 and the side wall is directly polished and opened, it is considered that when a normal worker holds a manual carving knife, the arm lifts up. angle, the upper half of the cutting edge 6 toward the end of the cutting edge 51 to be processed sometimes first contacts the side wall of the cutting edge 51, which will inevitably cause the side wall of the cutting edge 51 to be polished by the cutting edge 6 to form a step with a larger slope However, according to the requirements of the cutting edge 51, it is necessary to repeatedly grind and repair the step surface, and the operation accuracy is difficult to control, which makes the whole cutting edge 51's fronting process more difficult.
