Description

Tungsten steel coating forming hook knife

Technical Field

The utility model relates to the technical field of forming bush-hooks, in particular to a tungsten steel coating forming bush-hook.

Background

In order to improve the processing efficiency and reduce the production cost, the forming processing cutter replaces the traditional standard cutter more and more, and the precision is higher in the integral forming in the processing process.

However, the forming cutter has the weakness that the cutting edge of the forming cutter has a plurality of sections of profiles, the heights of the cutting edges are different, the geometric parameters of the cutting edges of certain sections cannot meet the requirement of the optimal processing state, the cutting lines and the different colors are easy to appear on certain parts of the surface of a workpiece during processing, the processing quality is influenced, particularly the processing of a high-gloss profile surface is difficult, the surface quality is poor, and the common forming cutter cannot meet the processing requirement.

Disclosure of utility model

In order to overcome the defects in the prior art, the utility model provides a tungsten steel coating forming hook knife to solve the problems in the background art.

The tungsten steel coating forming hook knife comprises a knife handle, wherein a connector is arranged on the surface of the knife handle, a knife head is arranged at the top of the connector, a blade is arranged at the top end of the knife head, and the blade is inclined at 45 degrees and forms a barb T with the knife head; the cutter handle is characterized in that the top end of the cutter handle is provided with a cut surface, one side of the cut surface is provided with an opening, the cutter tip of the cutter blade is provided with an R-shaped fillet, the cutter tip of the cutter blade is provided with an axial rear angle and a radial rear angle, and the rear side surface of the cutter blade is concave.

Preferably, the cutter handle and the cutter head are both made of wear-resistant ultrafine particle integral hard alloy, and the surface of the cutter handle and the cutter head is sprayed with the Barstool Cha Sigao hardness nano coating.

The utility model has the technical effects and advantages that:

1. The tool bit and the blade are arranged in the barb T shape, so that the contour of the workpiece can be re-carved on the workpiece, the contour shape required by the workpiece is formed by feeding a machining center, the influence on the workpiece during machining the workpiece can be avoided, the machined surface of the workpiece has no tool marks, no different colors and small surface roughness;

2. The Barr Cha Sigao hardness nano coating is sprayed on the surfaces of the cutter handle and the cutter head, so that the service life of the cutter can be effectively prolonged.

The numerical control cutting tool is characterized by comprising a tool handle 1, a tool bit 2, a tool bit 3, a blade 4, an opening 5, a section 6 and a connector.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The tungsten steel coating forming hook knife shown in the attached drawings 1-4 comprises a knife handle 1, a connector 6 is arranged on the surface of the knife handle 1, a knife head 2 is arranged at the top of the connector 6, a knife blade 3 is arranged at the top end of the knife head 2, the knife blade 3 is inclined at 45 degrees and forms a barb T shape with the knife head 2, a tangential surface 5 is arranged at the top end of the knife handle 1, an opening 4 is formed on one side of the tangential surface 5, the knife tip of the knife blade 3 is set to be R0.1 filleted corner excessively, the knife edge of the knife blade 3 is set to be at an axial relief angle of 3 degrees and at a radial relief angle of 10 degrees, the rear side surface of the knife blade 3 is concave inwards by 2 degrees, a barb T shape is formed through the knife head 2 and the knife blade 3, a workpiece contour can be re-carved on a workpiece, the workpiece is formed in a required contour shape during machining, influences on the workpiece can be avoided, the machined workpiece surface has no knife grain and no abnormal color, and has small surface roughness.

As shown in figures 1-4, the cutter handle 1 and the cutter head 2 are both made of wear-resistant ultrafine particle integral hard alloy, and the surface is sprayed with a Barstool Cha Sigao hardness nano coating, so that the service life of the cutter can be effectively prolonged.

The working principle of the utility model is that the profile is formed on the cutting edge of the blade 3, then the profile of the workpiece is carved on the workpiece, the profile shape required by the workpiece is formed by feeding a machining center, the influence on the workpiece when the workpiece is machined can be avoided by the tool bit 2 with the longitudinal section in a barb-shaped structure, the machined workpiece surface has no tool grain, no abnormal color and small surface roughness.
