Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of forming hook knives, and more specifically, to a tungsten steel coating forming hook knife. Background Art
[0002] In order to improve processing efficiency and reduce production costs, forming processing tools are increasingly replacing traditional standard tools. The processing process is integrated into one piece with high precision.
[0003] However, forming tools also have their weaknesses. Because the cutting edge of the forming tool has multiple contours with different heights, the tool geometric parameters cannot be taken into account. The cutting edge geometric parameters of some sections cannot meet the requirements of the optimal processing state. During processing, knife marks and discoloration are prone to appear on certain parts of the workpiece surface, affecting the processing quality. In particular, it is more difficult to process high-gloss contour surfaces and the surface quality is poor. Conventional forming tools can no longer meet the processing requirements. Utility Model Content
[0004] In order to overcome the above defects of the prior art, the utility model provides a tungsten steel coating forming hook knife to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tungsten steel coated molded hook knife, comprising a handle, a connector is provided on the surface of the handle, a cutter head is provided on the top of the connector, a blade is provided on the top of the cutter head, and the blade is arranged to be inclined at 45 degrees to form a barbed T-shape with the cutter head; a cutting surface is provided on the top of the handle, and an opening is provided on one side of the cutting surface; the tip of the blade is arranged to be R. rounded transition; the blade edge is arranged to be an axial rear angle and a radial rear angle, and the rear side surface of the blade has an inward concavity. The above-mentioned technical solution is adopted to facilitate one-piece molding during the processing process, with high precision, and the finished product has no knife marks, no discoloration, and low surface roughness.
[0006] Preferably, the shank and the cutter head are both made of wear-resistant ultrafine particle integral cemented carbide, and the surface is sprayed with Balzers high-hardness nano coating. The above technical solution is adopted to improve the quality of the blade and extend its service life.
[0007] Technical effects and advantages of the utility model:
[0008] 1. By setting the cutter head and the blade to a barbed T-shape, the contour of the workpiece can be reproduced on the workpiece, and the required contour shape of the workpiece can be formed through the machining center. In addition, the workpiece can be avoided from being affected during machining. The surface of the machined workpiece has no knife marks, no discoloration, and low surface roughness;
[0009] 2. By spraying Balzers high-hardness nano coating on the surface of the tool handle and tool head, the service life of the tool can be effectively extended. BRIEF DESCRIPTION OF THE DRAWINGS
