Description

Technical Field

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

[0002] Heat treatment refers to a metal heat processing process in which the material is heated, kept warm and cooled in the solid state to obtain the expected structure and performance. The heat treatment process generally includes three processes: heating, keeping warm and cooling. Cooling is an indispensable step in the heat treatment process. The cooling method varies with the process, mainly to control the cooling speed. Generally, annealing has the slowest cooling speed, normalizing has a faster cooling speed, and quenching has an even faster cooling speed. However, there are different requirements for different types of steel. For example, air-hardened steel can be hardened at the same cooling speed as normalizing.

[0003] After massive searches, the prior art was found: Publication No. CN209052733U discloses a heat treatment cooling device, which belongs to the field of heat treatment technology and includes a frame; a roller, which is rotatably arranged on the frame; and a plurality of first air sources, which are arranged above and below the roller. The heat treatment cooling device provided by the utility model has a plurality of first air sources arranged above and below the roller. During production, the workpiece is placed on the roller for cooling, and the upper and lower surfaces of the workpiece are blown and cooled at the same time, thereby achieving uniform cooling of the workpiece and ensuring the quality of the workpiece.

[0004] Another example: Publication No. CN111363892A discloses a heat treatment cooling device, which relates to the field of heat treatment technology. The heat treatment cooling device includes two cooling chambers and two feeding devices. Each cooling chamber is provided with a cooling pool for accommodating a cooling medium. The cooling chamber is provided with a feed port and a discharge port. The cooling medium in the first cooling pool is cooling water, and the cooling medium in the second cooling pool is cooling oil. The discharge port of the first cooling chamber is connected to the feed port of the second cooling chamber. The two feeding devices are respectively arranged in the first cooling pool and the second cooling pool. The feeding device has a bearing surface for bearing the workpiece. The bearing surface has a movable stroke for vertical movement and a movable stroke for moving from the feed port to the discharge port. The heat treatment cooling device provided by the present invention can select the cooling speed according to different heat treatment processes and the quality requirements of the workpiece, save costs, and have various cooling methods.

[0005] In summary, the existing heat treatment cooling mostly adopts air cooling, water cooling and oil cooling. However, in the screw production process, due to the irregular shape of the screws, the screws are easily accumulated during the air cooling process, which may cause incomplete cooling, thereby affecting the effect of the screw heat treatment.

[0013] Preferably, the hollow shafts are all located between the rotating shafts, the temperature sensors correspond to the positions of the rotating shafts, and the surface of the conveyor belt is designed to be hollow.

At the same time, the air pipe injects air into the hollow shaft, and the air is ejected through the nozzle. After passing through the surface of the conveyor belt, the screws on the surface of the conveyor belt are cooled, which can achieve a more comprehensive cooling effect.
