Description

TECHNICAL FIELD

[0001] The utility model relates to lathe numerical control tool equipment field especially relates to a novel center water reamer. BACKGROUND

[0002] In the metal cutting process, the finishing surface quality of aluminum alloy is affected by multiple factors, including the cutting parameters of the tool, the use of cooling liquid and the chip removal effect, etc. In particular, the pros and cons of the chip removal effect have two aspects of influence on the processing result: (1) influence on the surface quality: if the chip removal effect is not good, the aluminum chips generated in the cutting process cannot be discharged in time, which often rubs with the processing surface, causing surface scratches, thereby affecting the final surface quality; (2) influence on the processing tempo: when the chip removal effect is poor, in order to avoid the accumulation of aluminum chips in the cutting process, the operator often needs to reduce the feed rate of the tool per unit time, which directly leads to the extension of the processing cycle, thereby affecting the time efficiency of single piece processing. In order to solve this problem, the manufacturing industry generally uses a machine tool equipped with a high-pressure center water system, and combines a tool with a center water hole to process aluminum alloy, so as to ensure that the aluminum chips in the cutting process can be quickly discharged, thereby improving the surface quality and shortening the processing time. For example, the tool with center water disclosed in the patent with the authorization announcement number CN101745652B uses a forward side edge water hole at the front end of the cutting edge part of the tool with the minimum diameter, and a rear side water hole at the rear end part of the tool with the minimum diameter. In this way, during cutting, the aluminum chips generated are washed away in two directions by the high-pressure water jet of the machine tool through the forward and rear water holes of the tool, so that the aluminum chips generated during cutting can be easily washed away.

[0003] However, the forward water hole of the tool with the above structure is located at the front end, and the rear water hole is located at the rear end. This structure cannot wash the position between the forward water hole and the rear water hole, which affects the chip removal effect. UTILITY MODEL CONTENT

[0004] The purpose of the utility model is to provide a novel center water reamer, in which the water outlet end of the forward water hole is located at the rear end of the water outlet end of the rear water hole, so that the water washing can be fully covered, and the area between the forward water hole and the rear water hole can be effectively washed.

[0021] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figures 2-6 As shown, a novel center-outlet reamer includes a shank 1 and a cutting edge 2. The shank connects the cutting tool and is typically used to connect to a machine tool spindle, while the cutting edge is the working part that performs the cutting operation. The reamer has a water inlet channel 3 along its length, which guides the flow of coolant or cleaning fluid to effectively cool the tool and remove aluminum chips during the cutting process. One end of the water inlet channel extends to the front end of the cutting edge 2. A front side outlet 5, communicating with the water inlet channel, is located on the side end of the cutting edge 2 facing the front end of the cutting edge. A rear side outlet 6, communicating with the water inlet channel, is located on the side end of the cutting edge 2 facing the rear end of the cutting edge. The front side outlet 5 and the rear side outlet 6 are staggered, with the outlet end of the front side outlet 5 located behind the outlet end of the rear side outlet 6, ensuring full coverage and preventing the area between the front side outlet and the rear side outlet from being unable to be effectively rinsed.

[0024] In this embodiment, the front end of the cutting edge 2 is provided with a front water outlet 4 that communicates with the water inlet channel. The function of the front water outlet is to spray coolant directly from the front end of the cutting edge to help reduce the cutting temperature and effectively remove aluminum chips generated at the front end of the cutting edge.

[0025] In this embodiment, there are two of each of the front side outlet 5 and the rear side outlet 6.

[0026] In this embodiment, the front side outlet 5 and the rear side outlet 6 are staggered at 90° around the blade. This arrangement ensures that the area around the blade is evenly rinsed, preventing coolant from concentrating in one area and thus improving the cooling effect. It also ensures that the front side outlet 5 and the rear side outlet 6 do not interfere with each other during their arrangement. It is understood that other numbers of front side outlets 5 and rear side outlets 6 can also be used, where the angle between them is equal to 360° / the sum of the two numbers.

[0027] In this embodiment, the water outlet ends of the side front water outlet 5 and the side rear water outlet 6 are provided with water outlet plates, and the water outlet ends of the front water outlet 4 are provided with water outlet plates, which are provided with a plurality of micro-nozzles. This design enables the cooling liquid to be sprayed more uniformly around the cutting edge, further improving the discharge efficiency of aluminum chips and preventing the cooling liquid flow from being too large or too small, which affects the cutting effect.

[0028] In this embodiment, the included angle between the side front water outlet 5 and the side rear water outlet 6 and the reamer shaft is between 30°-60°. This angle design can optimize the spraying direction of the cooling liquid, which not only effectively cools the cutting edge, but also helps the aluminum chips to be discharged outward, avoiding the problem of blockage or backflow of the cooling liquid and the aluminum chips. Reasonable angle design helps to improve the cooling effect and the efficiency of aluminum chip removal.

[0029] In this embodiment, the corner between the water inlet channel 3 and the side front water outlet 5 and the side rear water outlet 6 is a streamline structure. The streamline design reduces the resistance of the water flow, enabling the cooling liquid to flow more smoothly to each water outlet. The streamline structure helps to improve the flow efficiency of the cooling liquid, thereby achieving better cooling and chip removal effect. The streamline design can also avoid the sharp change of the cooling liquid at the corner, further optimizing the stability and uniformity of the liquid flow.

[0030] This new center water outlet reamer is finely designed in terms of cooling liquid guidance and chip removal effect. Through the configuration of multiple water outlets, micro-nozzles, reasonable angles and streamline corner design, it ensures that the cooling liquid can fully cover the cutting edge during cutting process, maintaining the temperature and cleanliness of the tool. The staggered arrangement of the side front and side rear water outlets further enhances the cooling effect and the discharge capacity of the aluminum chips, thereby improving the machining efficiency and surface quality. Through this innovative design, the cutting process of aluminum alloy can be more efficient and accurate, reducing surface defects and processing delays caused by excessive temperature and aluminum chip accumulation.

[0031] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
