DETAILED DESCRIPTION

[0018] The technical scheme of the utility model will be clearly and completely described below in combination with the embodiments, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0019] Please refer to Figures 1-4As shown, a drying polishing device for a hard alloy cutter comprises a polishing machine 1, a chuck 2 is arranged on one side of the polishing machine 1, a support 3 is fixedly connected to the side of the polishing machine 1 opposite to the chuck 2, a telescopic mechanism 4 is fixedly connected to the support 3, a protective cylinder 5 is fixedly connected to the side of the telescopic mechanism 4 close to the chuck 2, and the telescopic mechanism 4 can adopt any linear motion mechanism such as an electric push rod.

[0020] The drying assembly comprises a drying cylinder 6 which is slidingly connected in the protective cylinder 5, one end surface of the drying cylinder 6 is fixedly connected to the output end of the telescopic mechanism 4, a connecting ring 7 is fixedly connected in the drying cylinder 6, a drying baffle 8 is fixedly connected to one side of the connecting ring 7, a variable-diameter section 9 is arranged on the drying cylinder 6, one end of the variable-diameter section 9 is provided with a drying section 10, one end of the drying section 10 is provided with a sealing section 11, the inside of the sealing section 11 is fixedly connected with a sealing gasket 12, a plurality of air outlet holes 13 are arranged on one side of the outside of the sealing section 11 and are annularly distributed, the outside of the variable-diameter section 9 and the drying section 10 is jointly provided with an axial flow guide groove 14 which is annularly distributed, and the outside of the drying section 10 is provided with a radial flow guide groove 15 which is also annularly distributed.

[0021] It should be noted that a dryer is arranged in the sealed space formed by the drying baffle 8 and the inner surface of the drying cylinder 6, which has the functions of heating and blowing, and is a mature technology. In order to facilitate the air inlet of the dryer, an air inlet fence is arranged at the tail end of the drying cylinder 6, and a plurality of round holes are uniformly distributed on the middle of the drying baffle 8 to facilitate the refinement of the airflow. The variable-diameter section 9 increases the wind speed by reducing the cross-sectional area, thereby improving the drying effect on the hard alloy cutter through the high-speed hot airflow. The sealing section 11 is used to reduce the gap between the drying cylinder 6 and the cutter at the tail end of the hard alloy cutter, so as to avoid the direct spraying of the humid airflow on the chuck 2, and the structure of the sealing section 11 makes the airflow turn and discharge outward from the air outlet holes 13. The axial flow guide groove 14 and the radial flow guide groove 15 are both used to drain most of the water in the air that condenses into liquid, so that it drips downward from the drying cylinder 6, and a small part of it is heated by the residual heat of the drying cylinder 6 shell to speed up evaporation, thereby reducing the water residence time. Through the arrangement of the drying assembly, the telescopic movement of the drying cylinder 6 in the protective cylinder 5 can be realized by the cooperation of the telescopic mechanism 4, the protective cylinder 5 and the drying cylinder 6. After the polishing of the alloy cutter is completed, the drying cylinder 6 is extended to cover the outside of the alloy cutter, and the polished alloy cutter is subjected to drying treatment. During the drying process, the airflow carrying water mist will be discharged outward through the air outlet holes 13, and part of the water mist will be liquefied by cooling and will fall downward under the action of gravity through the axial flow guide groove 14 and the radial flow guide groove 15 and be discharged outward from the water falling groove 16, thereby reducing the attachment time and amount of water on the outside of the drying cylinder 6, slowing down the corrosion speed of the part, and protecting the surface quality of the drying cylinder 6 after long-term use.

[0022] The outer side of the drying cylinder 6 is provided with guiding protrusions on the front and back sides and the top, and the corresponding guiding grooves are formed in the protection cylinder 5, the guiding protrusions and the guiding grooves are matched with each other to guide the movement of the drying cylinder 6 in the protection cylinder 5, and the positioning accuracy is improved.

[0023] The bottom of the protection cylinder 5 is provided with a water falling groove 16, which is located below the variable-diameter section 9 and the drying section 10, the water falling groove 16 can facilitate the water droplets falling downward from the radial flow groove 15 to enter the water filter plate arranged in the polishing machine 1, the water can be discharged outward from the drying cylinder 6, and the service life of the structure is improved.

[0024] The angle between the center line of the two ends of the radial flow groove 15 and the line connecting the centers is one hundred and eighty degrees, and the two end faces of the radial flow groove 15 are perpendicular to the horizontal plane of the inner surface of the polishing machine 1, so that the water accumulated in the radial flow groove 15 can quickly fall under the action of gravity, and the water loss is accelerated.

The preferred embodiments do not describe all the details, and the utility model is not limited to the specific implementation. Obviously, according to the content of the specification, many modifications and changes can be made.
