Description

Technical Field

[0001] The utility model relates to the technical field of roller lathes, in particular to a cooling device for a numerically controlled roller lathe. Background Art

[0002] The roll lathe is one of the important branches of metal cutting machine tools. It is mainly used to process the rolls to achieve the preset shape and precision. During the rolling process of metal products, the rolls will undergo micron-level physical and chemical wear, resulting in the gradual loss of the geometric accuracy of the roll surface, which in turn affects the quality of the rolled material and the efficiency of the rolling mill. Therefore, the rolls that have lost their accuracy need to be repaired offline and can only be used again after the accuracy is restored. The roll lathe plays a key role in this process.

[0003] Compared with ordinary lathes, the biggest features of roll lathes are low speed, high torque, large cutting volume, and no requirement for thread turning; that is, there is no need for a strictly matched transmission chain between the main transmission system and the longitudinal and lateral feeds. In the actual use of CNC roll lathes, the cutting tool holder on the roll lathe needs to be cooled.

[0004] A Chinese patent for a CNC roller lathe cooling device (publication number CN211516097U) is proposed in the prior art to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: "It includes a base, and the two ends of the top of the base are respectively fixedly connected with a first fixed column and a second fixed column. A water tank is placed on the top of the base, and a water pump is arranged on the bottom surface of the water tank. The water pump is connected to the nozzle through a conduit. The tops of the first fixed column and the second fixed column are connected through a mounting plate, and a roller tool holder is installed on the mounting plate. A filter screen is arranged on the top of the water tank, and movable grooves are provided on the sides of the first fixed column and the second fixed column and above the water tank. The CNC roller lathe cooling device can cool the roller tool holder through the linkage relationship between the water tank, the water pump, the conduit, the nozzle, the mounting plate, the roller tool holder, the filter screen, the movable groove, the fixed rod, the pressure plate, the limit elastic block and the limit groove. The water can be recycled through the water pump and the conduit to avoid waste. The operation is simple and convenient, and it is easy to use." However, in this technology, in order to achieve water pumping for cooling, an additional water pump needs to be set up for driving, so as to pump water to the processing position for cooling, which makes the implementation cost relatively high. In addition, since the rotation speed of the spindle changes in real time during the cutting process, the real-time change of the cutting speed is affected. The roller and the cutter head will generate different degrees of heat at different cutting speeds. If a water pump is used for constant speed water spraying, the temperature of the cutter head and the roller will inevitably fluctuate, thereby affecting the effect of the roller processing. In addition, if the water pumping speed is flexibly controlled by automated equipment, not only the control system is troublesome and inconvenient to implement, but also the real-time speed working mode will inevitably affect the service life of the water pump. Therefore, the utility model proposes another CNC roller lathe cooling device that can control the water spraying speed along with the cutting speed. Utility Model Content

[0005] The utility model aims to provide a cooling device for a numerically controlled roll lathe to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0012] By adopting the above technical solution, when the piston plate moves toward the side close to the linkage rod, the one-way valve in the input pipe is turned on, and the one-way valve in the output pipe is blocked, thereby generating negative pressure in the piston cylinder and pumping water from the water tank; when the piston plate moves toward the side away from the linkage rod, the one-way valve in the input pipe is blocked, and the one-way valve in the output pipe is turned on, thereby generating positive pressure in the piston cylinder and spraying water from the nozzle to the cutting position.

During the processing, the motor in the main body 1 is controlled to work, so that the main shaft rotates, and then the roller is driven to rotate at a high speed. During the process, the position of the cutter head is controlled by the first and second servo modules so that the cutter head can cut the high-speed rotating roller, and the rotation of one of the chucks 8 will drive the gear ring 9 to rotate, and then the driven gear 11 will rotate accordingly, and drive the transmission shaft 24 to rotate, and then the reciprocating ring 16 is driven to reciprocate through the spiral groove 18 and the transmission buckle 17 (the spiral groove 18 is threadedly connected to the reciprocating ring 16, and the reciprocating ring 16 is limited by the linkage rod 15 and can only move in a straight line), and through the linkage rod 15 drives the piston plate 14 to perform piston movement in the piston cylinder 13. When the piston plate 14 moves toward the side close to the linkage rod 15, the one-way valve in the input pipe 1901 is turned on, and the one-way valve in the output pipe 1902 is blocked, thereby generating negative pressure in the piston cylinder 13 and pumping water from the water tank 20; when the piston plate 14 moves toward the side away from the linkage rod 15, the one-way valve in the input pipe 1901 is blocked, and the one-way valve in the output pipe 1902 is turned on, thereby generating positive pressure in the piston cylinder 13 and spraying water from the nozzle 22 to the cutting position to complete cooling.
