Description

Technical Field

[0001] This utility model relates to the technical field of vertical quenching tools, and in particular to a vertical quenching machine tool. Background Technology

[0002] Quenching is an important metal heat treatment process. By heating a metal workpiece to a certain temperature and then rapidly cooling it, the hardness, strength, and wear resistance of the metal are significantly improved. It is widely used in many fields such as machinery manufacturing, automotive industry, and aerospace. Traditional quenching equipment has played an important role in meeting the needs of industrial production. However, with the continuous development of industrial technology, higher requirements have been placed on the performance, precision, and efficiency of quenching equipment.

[0003] Some traditional quenching machine tools have relatively fixed structural designs, making it difficult to achieve efficient and precise quenching for workpieces of different shapes and sizes. For example, for long shaft workpieces, traditional horizontal quenching machine tools are prone to uneven quenching during clamping and quenching due to the workpiece's own weight and length, resulting in inconsistent hardness in different parts of the workpiece and affecting product quality. During the quenching process, precise control of heating and cooling rates is crucial to ensuring workpiece quality. Traditional quenching machine tools have limited control precision in their heating and cooling systems, making it difficult to accurately regulate key parameters such as temperature and time. This may lead to dimensional deviations and deformations in the workpiece after quenching, increasing the difficulty and cost of subsequent processing, and even causing the workpiece to be scrapped. Therefore, these problems need to be addressed. Utility Model Content

The first motor 4 has a first lead screw 5 mounted on its output shaft via a coupling. The first lead screw 5 facilitates the lifting and lowering of the fixed block 6. The first lead screw 5 is threadedly connected to the fixed block 6, which facilitates the installation of the positioning frame 7. The positioning frame 7 is fixedly connected to the front end of the fixed block 6, which facilitates the installation of the positioning stake 8. The positioning stake 8 is installed at the front end of the positioning frame 7, which facilitates the installation of the positioning drill bit 9. The positioning drill bit 9 is installed at the bottom end of the positioning stake 8, which facilitates pressing down on the positioning workpiece. The chain 3 runs through both sides of the positioning frame 7.

[0022] In this utility model, the cooling mechanism includes a second motor 10 installed on one side of the first motor 4, which facilitates the rotation of the second lead screw 12; a universal joint 11 is installed on the output shaft of the second motor 10, which facilitates the engagement of the second lead screw 12; the second lead screw 12 is installed at the bottom of the universal joint 11, which facilitates the lifting and lowering of the cooling frame 13; the lower end of the second lead screw 12 is threadedly connected to the cooling frame 13, which facilitates the installation of drain pipes 14; multiple drain pipes 14 are installed on the cooling frame 13, which facilitates the protection of pipes 16; each drain pipe 14 is equipped with an independent valve, and a water pump 15 is installed in the middle of the support frame 2, which facilitates the pressurization of the drain pipes 14; a pipe 16 is provided at the bottom of the water pump 15, which facilitates the cooling of the quenching drill bit 20; the pipe 16 is connected to the cooling frame 13 through a flexible hose, and the heating mechanism includes... A third motor 19 is installed inside the base 1, which drives the quenching drill bit 20 to rotate. The quenching drill bit 20 is installed at the output end of the third motor 19, which facilitates the quenching of the workpiece. Movable components are installed on both sides of the upper end of the third motor 19, and heating chambers 17 are installed on both sides of the movable components, which facilitate the heating of the heating rings 18. Heating rings 18 are fixed to the inner side of both heating chambers 17, which facilitate the heating of the quenching area of ​​the workpiece. The two heating rings 18 are longitudinally staggered. The movable components include multiple guide rails installed in a crisscross pattern.

[0023] Working Principle: In use of this invention, the object to be processed is first placed on the device using a crane. Then, the power is turned on, and handwheel 21 is rotated, driving the third lead screw 22 to rotate. This adjusts the movement of the heating chamber 17 along the X and Y axes. Once the position is determined, the process stops. Simultaneously, the first motor 4 drives the first lead screw 5 to rotate, which in turn drives the fixing block 6 and positioning frame 7 to rise and fall. The chain 3 also assists in the lifting and lowering process to prevent the first lead screw 5 from being unable to withstand excessive loads. The positioning frame 7 drives the positioning stake 8 and positioning drill bit 9 to rise and fall, bringing them into contact with the top surface of the object to be processed and applying a downward force. The bottom of the workpiece comes into contact with the quenching drill bit 20. At this time, the third motor 19 drives the quenching drill bit 20 to rotate at high speed, and the heating ring 18 is activated to quench the bottom of the workpiece. At the same time, the second motor 10 drives the second lead screw 12 to rotate, which in turn drives the cooling rack 13 to rise and fall. When it reaches the appropriate height, the pipe 16 at the corresponding position is opened according to the quenching requirements. Under the pressure of the water pump 15, the water cools the quenching area. The workpiece is quenched through the cooperation of the quenching drill bit 20, the heating ring 18 and the pipe 16. After quenching, the workpiece is taken out, the device is reset, and the power is turned off.
