Description

Technical Field

[0001] This utility model relates to the field of milling cutter equipment technology, specifically to a gradient-coated insert with anti-chipping and enhanced cutting edge. Background Technology

[0002] Coated cutting tools are prepared by applying a thin layer of wear-resistant refractory metal or non-metallic compound (or it can be applied to superhard materials such as ceramics, diamond, and cubic boron nitride inserts) to the surface of a high-strength and tough cemented carbide or high-speed steel (HSS) substrate using a vapor deposition method. The coating acts as a chemical and thermal barrier, reducing diffusion and chemical reactions between the tool and the workpiece, thereby reducing substrate wear. Coated cutting tools possess characteristics such as high surface hardness, good wear resistance, stable chemical properties, heat and oxidation resistance, low coefficient of friction, and low thermal conductivity. During cutting, they can increase tool life by 3-5 times compared to uncoated tools, increase cutting speed by 20%-70%, improve machining accuracy by 0.5-1 grade, and reduce tool consumption costs by 20%-50%.

[0003] A previously published patent (publication number CN207735653U) discloses an effective anti-vibration and anti-chipping milling cutter, comprising a shank and a helical cutting edge. The helical cutting edge is located on the end face of the shank and includes at least four end teeth arranged radially along the end face of the shank with unequal included angles. The end teeth include a first back edge and a second back edge, which form an included angle ω with each other. This invention not only increases the cutting edge rigidity and cutting force of traditional milling cutters, but also achieves anti-vibration effects by using non-equidistantly arranged long and short teeth. Furthermore, the end tooth inclination angle of this invention is opposite to that of standard milling cutters, with the back edge consisting of a first back edge and a second back edge, which form an included angle protruding towards the end face. This disperses the cutting resistance, causing the force to be distributed towards the central axis during cutting, thus preventing chipping.

[0004] However, there are some problems with the use of existing gradient-coated inserts: 1. Gradient-coated inserts on the market are prone to breakage or deformation under stress during operation. Their overall cutting edge strength is low, making them unsuitable for long-term or high-intensity use, reducing their overall usability. End mills with easily broken cutting edges are also less safe. 2. Gradient-coated inserts on the market have low gradient installation properties, making them unsuitable for quick use and reducing overall connection and disassembly flexibility. Utility Model Content

[0005] The purpose of this invention is to provide a gradient-coated blade with anti-chipping and enhanced cutting edge to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a gradient-coated blade with anti-chipping and enhanced cutting edge, comprising a mounting base, an anti-chipping and enhanced component disposed on the surface of the mounting base, and a mounting and disassembly component disposed on the surface of the mounting base;

[0007] The anti-collapse reinforcement component includes a blade body disposed on the surface of the mounting base. The blade body has cutting edges on its surface, which are distributed in a ring on the outer side of the blade body surface. Reinforcing metal is embedded and connected inside the cutting edges, and the reinforcing metal and the cutting edges work together.

[0008] The installation and disassembly assembly includes an extension hole on the surface of the mounting base, an internal thread on the inner surface of the extension hole, and a guide hole at the bottom of the inner side of the extension hole for external installation.

[0009] As a further improvement of this invention, the anti-chipping reinforcement component also includes a wear-resistant layer coated on the surface of the reinforcing metal, the wear-resistant layer being made of wear-resistant lead plating.

[0010] As a further improvement of this utility model: oblique cuts are provided on both sides of the blade extension end, and the reinforcing metal is made of wear-resistant alloy.

[0011] As a further embodiment of this utility model: a stepped seat is detachably connected to the surface of the mounting base, a blade post is detachably connected to the surface of the stepped seat, and a blade body is connected to one end of the blade post.

[0012] As a further improvement of this utility model, the installation and disassembly assembly also includes an extension column fixedly connected to the bottom of the blade post, and the surface of the extension column is provided with external threads.

[0013] As a further embodiment of this utility model: the extension post is movably connected inside the extension opening, the external thread surface is fitted with an internal thread, one end of the extension post is fixedly connected to a guide post, and one end of the guide post is movably connected inside the guide hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In use, this invention uses a blade post to install and fix the blade body. Multiple cutting edges are formed on the blade body surface to create a working cutting edge. Reinforcing metal is connected inside the cutting edges, and this reinforcing metal is integrally manufactured with the blade body to prevent detachment during use. The reinforcing metal enhances the internal strength of the cutting edge, reducing the possibility of breakage. Both the inner side of the cutting edge and the surface of the reinforcing metal are coated with a wear-resistant lead-plated coating, increasing overall wear resistance and preventing breakage due to metal fatigue, thus increasing durability. Furthermore, the gradient-coated blade is less prone to breakage or deformation under stress during operation, exhibiting high overall cutting edge strength, facilitating long-term or high-intensity use, improving overall usability, and reducing the likelihood of the cutting edge breaking.

[0016] In this invention, when installing the blade body, a blade post is fixedly connected to one end of the blade body to increase its connectivity with the outside. One end of the blade post is connected to an extension hole on the surface of the mounting base via a fixedly connected extension post. The external thread on the surface of the extension post engages with the internal thread inside the extension hole to increase overall connectivity. When the extension post is connected to the extension hole, a guide post fixedly connected to one end of the extension post connects with a guide hole inside the extension hole to further enhance overall connectivity. As a result, the gradient-coated blade has high overall gradient installation capability, facilitating quick use and improving overall connection and disassembly. Attached Figure Description
