According to another embodiment of the utility model, the first driving device and the second driving device are both linear actuators, one end of each linear actuator is hinged on the support, and the other end of each linear actuator is hinged on one end of the split body. When the linear actuating element extends or shortens, the linear actuating element rotates along a hinge point on the bracket, and meanwhile, the split bodies are driven to rotate along the rotating connection positions, namely, when the linear actuating element extends, the split bodies can be opened; when the linear actuating element is shortened, the split bodies are closed to form an arc shape.
According to another embodiment of the present invention, it is further included that the linear actuator is a cylinder or an electric cylinder. The air cylinder or the electric cylinder is a common linear execution element in the prior art, and is convenient for automatic control.
According to another embodiment of the present invention, it is further comprised that the spray head is a rotary spray head. And adjusting the angle of the spray head when the mandrel is cooled according to requirements so as to obtain better spray cooling effect.
The utility model has the advantages that the split type opening and closing are driven by the driving device, and the automation degree is high. The device is quick and convenient to use, and can quickly cool the mandrel from outside to inside through continuous spraying, so that the quenching tissue can meet the requirements.

fig. 2 is a split open schematic view of the present invention.
In the figure, 1, a bracket, 2, a first split, 3, a second split, 4, a spray head, 5, a first driving device, 6 and a second driving device are shown.
Detailed Description
As shown in fig. 1 to 2, which are schematic structural diagrams of the present invention, a high wear-resistant mandrel spray quenching device is characterized by comprising a support 1, wherein the support 1 is rotatably connected with a first split body 2 and a second split body 3, the first split body 2 and the second split body 3 form an arc shape, spray heads 4 are uniformly arranged on the inner wall of the arc shape, the first split body 2 is driven to rotate by a first driving device 5, the second split body 3 is driven to rotate by a second driving device 6, and the first driving device 5 and the second driving device 6 are both mounted on the support 1.
The specific principle is as follows: when the mandrel is heated and insulated and needs to be cooled, the first split body 2 and the second split body 3 are opened in a rotating mode by adopting the device, the device is lowered to the position of the mandrel, the first driving device 5 and the second driving device 6 drive the first split body 2 and the second split body 3 to close in a rotating mode respectively to form an arc-shaped structure, the atomizing head 4 of the inner wall is aligned to the cylindrical surface of the mandrel, the whole cylindrical surface area can be subjected to atomizing cooling, and the mandrel core can be cooled rapidly due to continuous atomizing. A plurality of groups of spraying devices can be arranged according to the length of the mandrel, and cooling within the whole length range is carried out. After cooling is finished, the first driving device 5 and the second driving device 6 respectively drive the first split body 2 and the second split body 3 to rotate and open, and therefore the device is removed. The device is quick and convenient to use, and can quickly cool the mandrel from outside to inside through continuous spraying, so that the quenching tissue can meet the requirements.
According to another embodiment of the present invention, it further includes that the first driving device 5 and the second driving device 6 are both linear actuators, one end of each linear actuator is hinged on the bracket 1, and the other end of each linear actuator is hinged on one end of the split body. When the linear actuating element extends or shortens, the linear actuating element rotates along a hinge point on the support 1, and meanwhile, the split bodies are driven to rotate along the rotating connection positions, namely, when the linear actuating element extends, the split bodies are opened; when the linear actuating element is shortened, the split bodies are closed to form an arc shape.
According to another embodiment of the present invention, it is further included that the linear actuator is a cylinder or an electric cylinder. The air cylinder or the electric cylinder is a common linear actuating element in the prior art, and is convenient for automatic control.
According to another embodiment of the utility model, it is further comprised that said spray head 4 is a rotary spray head. When the mandrel is cooled, the angle of the spray head 4 is adjusted as required, so as to obtain better spray cooling effect.
