[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0026] Please refer to Figure 1-6 , the embodiments of the present utility model provide a technical solution: a multi-functional diamond tool for reverse chamfering, including a tungsten carbide tool body 1, a cutting-edge diamond blade 2, a four-tooth cutting head 3, an internal cooling structure 4, and an open chip groove 5. Its characteristics are that the tungsten carbide tool body 1 and the cutting-edge diamond blade 2 are nested and welded. By setting the tool cutting edge to use welded super-hard cutting-edge diamond blade 2 material, the tool has a good service life, and at the same time, the surface finish of the processed product can meet the requirements of customers.
[0027] The internal of the tungsten carbide tool body 1 is provided with a direct-injection internal cooling structure 4.
[0028] The tungsten carbide tool body 1 and the cutting-edge diamond blade 2 are vacuum welded. This welding method effectively avoids the uneven heat absorption caused by the influence of the external environment during welding. It effectively prevents defects such as the generation of bubbles during the welding process, the damage of the tool material, and the insecure welding, and improves the service life of the tool.
[0029] The internal cooling structure 4 is provided with direct-injection cooling at the cutting edge, which can cool the 4-tooth cutting edge of the tool at the same time and improve the chip removal efficiency.
[0030] As shown in Figure (2), the cutting edge part adopts a four-tooth cutting head 3 for simultaneous chip removal method, which ensures the strength of the tool and increases the service life of the tool. The front end adopts an R-angle guide, which can effectively prevent the cutting edge of the tool from chipping. A finishing edge L1 is reserved axially on the outer diameter to ensure that the surface finish of the product processed by the tool can meet the usage requirements of customers. The β angle is the clearance angle, which is also the clearance dimension. It needs to be reasonably designed according to the usage situation of customers, and at the same time takes into account the functions of clearance and tool rigidity. The cutting edge adopts a two-back-angle method, which not only ensures the strength of the tool but also reduces the friction with the workpiece. The clamping handle is designed according to the clamping of the customer's machine tool.
[0031] As shown in Figure (3), this is a schematic diagram of the counterboring processing of the tool. The usage conditions are that both are applicable.
[0032] As shown in Figure (4), this is a schematic diagram of the boring processing of the tool. The usage conditions are that both ( γ ≤ β / 2 or there is a relief groove for clearance can be applied.
[0033] As shown in Figure (5), this is a schematic diagram of tool reaming machining. The usage conditions are that both can be applied.
[0034] As shown in Figure (6), this is a schematic diagram of tool reverse chamfering machining. The usage conditions are that both (α = δ, h2 ≤ L3 - L2, h1 ≤ L - L4) can be applied.
[0035] The tool machining material is aluminum alloy. The machine tool used requires a milling-around function during boring reverse chamfering machining.
[0036] The specific dimensions of the tool can be designed according to the product dimensions provided by the customer and the number of functions required. This further solution only provides a machining idea and is not applicable to all products.
[0037] Working principle: When in use, to improve the service life of the tool, the tool edge adopts a welded ultra-hard edge diamond blade 2 material, which is not easily worn during machining. And center holes are reserved at both ends of the tool, enabling the edge blades to be replaced and repaired in multiple places, with high utilization rate. Through this structure, the service life of the tool is improved; to improve the chip removal efficiency of the tool, by setting an internal cooling structure 4, the cutting temperature is effectively reduced, and an open chip pocket 5 is added to enable the flying chips to quickly discharge along the groove. Through this structure, the chip removal efficiency of the tool is improved; to achieve the multi-function of the tool, by designing special dimensions, the tool can meet different machining requirements and achieve the requirements of the multi-function of the tool.
[0038] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
