Description

Technical Field

[0001] The utility model relates to the technical field of mechanical heat treatment, in particular to a spray-type cooling device for heat treatment. Background Art

[0002] Heat treatment technology is a commonly used processing method in the machinery industry to improve the mechanical properties of workpieces. The so-called heat treatment is to heat the workpiece to a certain temperature, keep it warm, and then cool it. The cooling methods include oil cooling, water cooling and air cooling. There are currently two methods of air cooling. One method is to place the workpiece after heat treatment in the air and let it cool naturally. The other method is to use a blower to blow air to the workpiece after heat treatment to increase the cooling speed.

[0003] A heat treatment spray cooling device with application number CN201120322759.3 has a water tank, two water spray pipes connected to a water pump at the bottom of the water tank, a perforated steel plate above the water tank, two frequency-modulated blowers on one side of the water tank, the blowers and the water pump are connected to the same power supply system, and a high-pressure sprayer is between the blowers, which is connected to the water tank with a water pipe.

[0004] The above patent document has the beneficial effect of not only controlling the cooling speed to a certain extent, improving the uniformity of workpiece cooling, and ensuring the heat treatment quality of the workpiece, but also reducing the time and space occupied while ensuring the heat treatment quality of the workpiece. However, the workpieces that need to be heat treated are directly placed in the water tank and cooled by the upper and lower nozzles. The bottom of the workpiece is directly in contact with the bottom surface of the water tank. Even if there are holes, there are still some positions that are not sprayed with coolant, which can easily cause uneven cooling of the workpiece surface and generate stress, thereby greatly reducing the subsequent production efficiency. Utility Model Content

[0005] The utility model aims to solve the problem that the bottom of the existing workpiece is directly in contact with the bottom surface of the water tank, and even if holes are provided, there are still some positions that are not sprayed by the coolant, which easily causes uneven cooling of the workpiece surface to generate stress, thereby greatly reducing the subsequent production efficiency. A spray cooling device for heat treatment is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A spray cooling device for heat treatment comprises a workbench, a water trough is provided on the top of the workbench, a driving motor is fixedly connected to the outer wall of the workbench, the driving motor is connected to symmetrically distributed moving blocks through a clamping structure, a servo motor is fixedly connected to the outer wall of the moving block, the servo motor is connected to a clamping cone through a rotating structure, a rectangular water tank is fixedly connected to the bottom end of the workbench, and the water tank is connected to a hose through a cooling structure.

[0008] Preferably, the clamping structure includes a symmetrically distributed sliding cavity, a bidirectional lead screw, and a sliding column. The sliding cavity is arranged on both sides of the top of the workbench, the bidirectional lead screw is rotatably connected to the inner wall of the sliding cavity, and the sliding column is fixedly connected to the inner wall of the sliding cavity.

[0009] Preferably, the moving block is slidably connected to the inner wall of the sliding cavity, the bidirectional lead screw and the sliding column are symmetrically arranged, the bidirectional lead screw is threadedly connected to the moving block, and the sliding column is slidably connected to the moving block.

[0010] Preferably, the rotating structure includes a support frame and a bearing.

[0012] Preferably, the hose passes through the outer wall of the water tank and is arranged above the workbench, and the through hole is adapted to the internal size of the water tank.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When the utility model is in use, the clamping structure and the cooling structure cooperate with each other so that the workpiece that needs heat treatment can be clamped on the water tank, and then the two sides of the workpiece are cooled more evenly through the atomizing nozzles on the upper and lower sides, thereby solving the problem of uneven cooling due to the bottom of the workpiece and the bottom of the water tank. The dispersed spray makes the cooling more uniform, so the production efficiency is greatly improved.

[0015] 2. When the utility model is in use, the rotating structure arranged on the back of the clamping cone can make the workpiece rotate slowly when being clamped, so that the contact surface of the cooling structure is more comprehensive during cooling, thereby further enhancing the cooling effect of the workpiece. The conical clamping cone makes the contact area smaller, and the uncooled area generated is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS
