[0002] Cold heading is the process of forming metal plasticity at room temperature. The cold heading process is used to manufacture fasteners. It is not only efficient and of good quality, but also requires less materials and is low in cost. However, the cold heading process has high requirements on the quality of raw materials. It uses automatic cold heading of cold-drawn copper, aluminum wire, iron wire, etc. It is a special equipment for producing hollow aluminum rivets and semi-hollow iron rivets.

[0003] Since the force between the cold heading machine and the raw material is very large, the raw material will heat up quickly in a short time, and the workpiece surface contains residual refrigeration oil sprayed during cold heading. In order to facilitate subsequent transfer and storage, it needs to be cooled. Therefore, we propose a cold heading machine material cooling device. Utility Model Content

[0022] See also Figure 1-2 The utility model provides a technical solution: a cold heading machine material cooling device, comprising a bottom plate 1 and a material barrel 2, the material barrel 2 is laterally supported and placed above the bottom plate 1, and support blocks 11 are supported and fixed between the bottom of both sides of the material barrel 2 and the bottom plate 1, and the support blocks 11 are tightly attached to the outer surface of the material barrel 2, which can provide stable support for the material barrel 2 laterally and avoid rolling when the material barrel 2 is supported and placed on the surface of the bottom plate 1.

[0023] An upper opening 21 connected to the interior of the lower barrel 2 is provided above the lower barrel 2. The lower barrel 2 is supported below the lower opening of the cold heading machine by the bottom plate 1 so that the upper opening 21 is located directly below the lower opening. The workpiece discharged from the cold heading machine can enter the lower barrel 2 from the upper opening 21.

[0024] A roller 3 is installed in the discharge barrel 2 so as to rotate horizontally. A motor 32 is installed on the right outer surface of the discharge barrel 2 at the right end of the roller 3. The motor 32 is connected to the roller 3. When the motor 32 is started, the roller 3 is driven to rotate clockwise. A plurality of mesh plates 31 are evenly fixed on the outer ring of the roller 3. The ends of the mesh plates 31 are close to the inner wall surface of the discharge barrel 2. The roller 3 drives the mesh plates 31 to rotate clockwise at the same time. The workpiece entering the discharge barrel 2 is also driven by the mesh plates 31 to rotate clockwise. A side port 22 connected to the interior of the discharge barrel 2 is opened at the lower side of the discharge barrel 2, which will first drive the workpiece to descend in height, pass through the bottom of the discharge barrel 2, and finally be pushed to the side port 22 for discharge.

[0025] An air inlet 23 and an air outlet 24 are respectively provided on the surface at the same height above both sides of the lower barrel 2. A baffle 4 is embedded and fixed inside the air inlet 23 and the air outlet 24. When the workpiece rotates to the position of the air inlet 23 or the air outlet 24, the baffle 4 blocks the workpiece from entering the air inlet 23 or the air outlet 24. A fan 231 is installed on the outer surface of the lower barrel 2 at the air inlet 23. The air outlet direction of the fan 231 is toward the inside of the lower barrel 2. External air can be blown into the lower barrel 2, and the heat of the workpiece is carried away by the airflow to cool it down.

[0026] The surfaces below the two sides of the discharge barrel 2 are respectively provided with water inlets 25 and water outlets 26 connected with the interior thereof, and a baffle 4 is embedded and fixed inside the water inlet 25 and the water outlet 26. When the workpiece rotates to the position of the water inlet 25 or the water outlet 26, the baffle 4 blocks the workpiece from entering the water inlet 25 or the water outlet 26. The water inlet 25 and the water outlet 26 cooperate to allow a swirling ring of flowing clean water or cleaning liquid to pass into the discharge barrel 2. When the workpiece rotates and is immersed in the clean water or the cleaning liquid, it can be cooled again. Cooling down in two steps can prevent the workpiece from overheating in a short period of time and affecting the structural strength, and can wash away the cold heading oil on the surface. The water inlet 25 and the water outlet 26 have the same height, and the height of the water inlet 25 and the water outlet 26 is less than the height of the side port 22, so as to prevent the clean water or the cleaning liquid from leaking from the side port 22 to the outside.

[0027] When in use, the lower barrel 2 is supported and placed at the discharge port of the cold heading machine through the bottom plate 1, and the upper port 21 is located directly below the discharge port of the cold heading machine, a horizontal collecting trough is placed at the position of the side port 22, or a conveyor belt is directly set below the side port 22, so that the water inlet 25 is connected to the clean water supply pipe, and the water outlet 26 is connected to the drainage pipe, and the clean water or cleaning liquid enters the lower barrel 2 from the water inlet 25 and is discharged from the water outlet 26 at the rear end. The water level in the lower barrel 2 is not higher than the height of the water outlet 26, the motor 32 and the fan 231 are connected to the control device and powered, the motor 32 is started to drive the roller 3 and the mesh plate 31 to rotate clockwise, and the fan 231 is started at the same time to blow air from the air inlet 23 to the inside of the lower barrel 2, and the air After flowing in the lower barrel 2, it is discharged from the air outlet 24 on the other side. The workpiece processed by the cold heading machine enters the lower barrel 2 from the upper opening 21. Under the action of the rotating mesh plate 31, the workpiece rotates clockwise with the workpiece. When passing between the upper air inlet 23 and the air outlet 24, the workpiece is blown away by the flowing air to cool the workpiece. Then the workpiece is driven by the rotating mesh plate 31 and immersed in clean water or cleaning liquid to wash away the refrigerant oil on the surface and further cool it down. Cooling in two steps can prevent the workpiece from overheating in a short period of time and affecting the structural strength. Finally, the mesh plate 31 continues to rotate and moves the workpiece toward the side opening 22, and finally is discharged to the outside from the side opening 22, collected in a collection tank, or transported away by a conveyor belt.
