Description

Technical Field

[0001] The utility model relates to the technical field of carbide tool manufacturing, and more specifically, to a formed barbed planer. Background Art

[0002] In the process of planing metal parts, a planer is needed. It refers to the tool used for planing, which can directly affect the accuracy, surface roughness and production efficiency of the workpiece.

[0003] At present, with the development of technology, structural parts in many industries mostly adopt one-piece die-casting technology, integrating multiple parts into one component, demonstrating the huge potential of this technology in improving production efficiency and reducing costs.

[0004] However, in the existing technology, internal structural parts are usually processed using inserts or broaches. However, these traditional processing methods are relatively simple in shape and structure. Due to space limitations, some special structures cannot be effectively processed. Especially at the moment when integrated die-casting technology is widely used, structural parts in many industries use this technology to integrate multiple parts into one component. Although this greatly improves production efficiency and reduces costs, it increases the difficulty of processing when individual internal structural parts require fine processing. Due to space limitations, ordinary tools cannot reach into the interior of the structure for fine processing.

[0005] In view of the above situation, the utility model proposes a shaped barb planer. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a shaped barb planer to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a formed barb planer, comprising a tool handle for holding or connecting to a processing machine tool and a tool head blade replicating the contour of the processed part, wherein the tool head blade is located at one end of the tool handle;

[0009] The tail of the tool handle is provided with an arc-shaped retraction arrangement;

[0010] The front end of the cutter head blade is provided with a reverse chip breaker groove.

[0011] Preferably, the blade of the cutter head and the handle are integrally arranged, and both the blade of the cutter head and the handle are made of cemented carbide.

[0012] Preferably, the blade is divided into a front angle and a back angle, and the angles of the front angle and the back angle are set to be the same, and the back angle is the same as the part profile.

[0013] Preferably, the avoidance barb matches the shape of the internal structure of the part.

[0014] Technical effects and advantages of this utility model:

[0015] 1.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] As attached Figure 1-4 The formed barb planer shown includes a shank 1 for holding or connecting to a processing machine tool and a cutter head blade 2 that replicates the contour of the processed part, wherein the cutter head blade 2 is located at one end of the shank 1, the cutter head blade 2 and the shank 1 are integrally arranged, and the cutter head blade 2 and the shank 1 are both made of cemented carbide.

[0024] Specifically, the formed barb planer is specifically composed of a handle 1 and a blade 2 in an integrated manner, and is designed for processing internal structural parts using integrated die-casting technology. It can process the side walls of the internal structure of the parts with high processing precision and can also process relatively complex shapes and structures;

[0025] The tool handle 1 can be held or connected to a processing machine tool. The cutter head blade 2 is the working part of the planer and is used to cut materials. The cutter head blade 2 accurately replicates the contour of the part to be processed, ensuring that the cutter head blade 2 can achieve high-precision cutting operations during the processing. At the same time, the cutter head blade 2 and the tool handle 1 are integrated into one piece and are both made of cemented carbide. This not only improves the overall rigidity and durability of the tool, but also ensures the stability and precision of the tool during the processing process, and can achieve high-precision cutting operations to meet the needs of fine processing of internal structural parts, so that the tool can penetrate into the internal structure of the part for processing, solving the problem that ordinary tools cannot be inserted due to space limitations, thereby improving processing efficiency.

[0026] The cutting edge of the blade 2 is provided with a avoidance hook 3, and the avoidance hook 3 matches the internal structure shape of the part. The avoidance hook 3 provided on the blade 2 of the cutter head and matching the internal structure shape of the part enables the planer to smoothly enter and process the difficult-to-reach areas in the internal structure of the part.

[0027] The tail of the tool handle 1 is provided with an arc tool retraction 4, which can effectively improve the rigidity of the tool during the processing and reduce the risk of tool damage caused by vibration or impact.

[0028] The front end of the cutter head blade 2 is provided with a reverse chip breaker groove 5, which helps to effectively break and remove chips during the machining process, thereby improving the machining efficiency and surface quality.

[0029] The blade 2 of the cutter head is divided into a front angle and a back angle, and the angles of the front angle and the back angle are set to the same, and the back angle is the same as the part contour. The front angle of the planer is set to 12°, and the front cutting surface is finely polished, which can significantly improve the sharpness and durability of the cutting edge, thereby further improving the processing accuracy and efficiency. The back angle of the planer is also set to 12°, and is accurately replicated to the cutting edge according to the part contour, ensuring stability and accuracy during the processing process.

[0030] Working principle of this utility model:

[0031] The present application provides a shaped barb planer, which can process the inner side wall of a structural part with high processing accuracy and can process relatively complex shapes and structures;

[0032] Specifically, in the planer of this structure, the contour of the tool blade is a replica of the contour of the part. The planer includes a cutter head blade 2 and a shank 1, both of which are integrally arranged and made of cemented carbide. The cutter head blade 2 is located at one end of the shank 1, ensuring the overall rigidity and durability of the tool. A avoidance hook 3 is provided at the cutting edge of the cutter head blade 2. The avoidance hook 3 matches the shape of the internal structure of the part, allowing the planer to smoothly enter and process the hard-to-reach areas of the internal structure of the part. In addition, the tail of the shank 1 is designed as an arc retraction 4, which improves the rigidity of the tool and ensures stability during the processing;

[0033] At the same time, a reverse chip breaker groove 5 is set at the front end of the cutting edge 2 of the cutter head. Its front angle is 12°, and the front cutting surface is finely polished to improve the quality of the cutting edge. The back angle is also 12° and is replicated to the cutting edge according to the contour of the part. During the processing, the tool and the workpiece do not rotate, and the barb moves upward relative to the workpiece, shaving off the chips layer by layer, ensuring high-precision cutting operations.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
