[0019] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0020] like Figures 1 to 3As shown, a carving knife structure with a long service life includes a connecting handle 1, the end of the connecting handle 1 is tapered, which can facilitate the connection of the connecting handle 1 with a processing machine, the bottom end of the connecting handle 1 is fixedly connected with a tip connecting section 2, the tip connecting section 2 and the connecting handle 1 can be welded, and the tip connecting section 2 and the connecting handle 1 can also be integrally processed to ensure the connection stability of the tip connecting section 2 and the connecting handle 1, the bottom end of the tip connecting section 2 is fixedly connected with a tip 3, and a cutting edge 4 is arranged on the tip 3, and the angle between the cutting edge 4 and the end face of the connecting handle 1 is 40°±2°, and the tip 3 is fixedly connected with the tip 3. The over-inclined cutting edge 4 can better perform cutting operations on the workpiece. The two symmetrical sides of the blade tip 3 are both provided with avoidance edges 5 corresponding to the position of the cutting edge 4. The avoidance edges 5 can facilitate the upward movement of cut chips, avoiding the accumulation of chips at the cutting edge 4, so that the cutting edge 4 can better perform cutting operations. The end of the blade tip 3 is provided with a reinforcement edge 6. The reinforcement edge 6 is formed by grinding off a part of the tip of the blade tip 3 on the basis of the existing blade tip 3. The reinforcement edge 6 can increase the contact area between the cutting edge 4 and the workpiece, avoiding the situation where the tip of the blade tip 3 and the cutting edge 4 are easily damaged.
[0021] As an optional technical solution of the utility model, the blade tip connecting section 2 and the blade tip 3 are an integrated structure, and a transition fillet 7 is provided at the connection between the blade tip connecting section 2 and the blade tip 3. The transition fillet 7 can disperse the force on the blade tip 3, thereby making the connection between the blade tip connecting section 2 and the blade tip 3 more secure.
[0022] As an optional technical solution of the present utility model, the material connecting the shank 1, the blade tip connecting section 2 and the blade tip 3 is all cemented carbide, which has high hardness, strength and wear resistance, thereby ensuring the structural strength of the shank 1, the blade tip connecting section 2 and the blade tip 3.
[0023] As an optional technical solution of the utility model, the thickness of the blade tip 3 gradually increases from bottom to top. The blade tip 3 with gradually increasing thickness can withstand a large force without breaking. In order to better illustrate the change in the thickness of the blade tip 3, the following figure is attached to the specification. Figure 3 To indicate that Figure 3 The thickness at the bottom of the middle blade tip 3 is 0.05 mm, the thickness at the middle of the blade tip 3 is 0.25 mm, and the thickness at the top of the blade tip 3 is 0.35 mm.
[0024] As an optional technical solution of the present invention, the length of the blade tip connecting section 2 is 2.5-2.7 mm, so that the blade tip connecting section 2 can be easily processed, thereby improving the convenience of processing the carving knife structure.
[0025] As an optional technical solution of the utility model, the angle between the reinforcing edge 6 and the cutting edge 4 is an obtuse angle, and the length of the reinforcing edge 6 is 0.1-0.14mm, which can ensure that the cutting edge 4 increases the contact area between the cutting edge 4 and the workpiece while performing normal cutting work, avoiding the situation in which all the force acts on the tip of the dagger 3 during the traditional cutting process of the workpiece, thereby greatly avoiding the damage to the tip of the blade 3.
[0026] As an optional technical solution of the present utility model, the angle between the avoidance blade 5 and the central axis of the connecting handle 1 is 20-28°, and the angle between the avoidance blade 5 and the central axis of the connecting handle 1 is marked as a.
[0027] This knife structure can be used to cut new materials, special films, soft glue and soft films with glass properties.
[0028] To sum up, the carving knife structure with a long service life is provided with a reinforcing edge 6 at the end of the blade tip 3, that is, the tip part of the cutting edge 4 is removed. The reinforcing edge 6 makes the blade tip 3 no longer have a tip structure, thereby improving the stability of the blade tip 3 and greatly avoiding the damage of the tip part of the blade tip 3. In addition, the thickness of the blade tip 3 gradually increases from bottom to top, and the blade tip 3 with gradually increasing thickness provides a stable support point for the cutting edge 4, so that the blade tip 3 can withstand greater force without collapse, thereby extending the service life of the blade tip 3, and greatly avoiding the situation where the damage of the blade tip 3 affects the product accuracy or even the product is scrapped, thereby ensuring the processing efficiency.
