Description

Technical Field

[0001] The utility model relates to the technical field of cold heading machines, and particularly relates to a centrifugal oil-water separation type fastener cold heading machine. Background Technique

[0002] A cold heading machine is an important stamping processing machine in mechanical manufacturing, which is specifically used for plastic forming of metals at normal temperature to mass-produce fasteners such as nuts and bolts. Its working principle is to transmit power through belt wheels and gears, realize linear motion through a crank connecting rod and slider mechanism, and use a punch and a die to cause plastic deformation or separation of the blank of the processed part, so as to form the required shape;

[0003] During the cold heading process, the metal material is subjected to a large pressure. In order to reduce friction, wear and control temperature, lubricating oil is usually used for lubrication. Some of these lubricating oils may evaporate or atomize under high temperature and pressure, and mix with moisture or other impurities in the air to form an oil-water mixture. Therefore, after the finished fasteners are blanked, the fasteners will enter the collection device together with a certain amount of oil-water mixture. Therefore, the Chinese utility model patent with the publication number CN205386354U: the blanking oil-water separation device of a cold heading machine, this application includes an oil-water separator arranged at the discharge port of the machine box. A channel for the material to pass through is arranged at the bottom of the oil-water separator, and a recovery mechanism for bringing the separated oil back into the machine box is arranged on the oil-water separator. A power mechanism is arranged on the recovery mechanism, which can achieve the separation effect of oil and water. However, after the oil and water are separated, the fasteners are still placed in the box. On the one hand, it brings certain difficulties to take out the fasteners from the box. On the other hand, the fasteners taken out from the box will still adhere to a certain amount of oil-water mixture, which increases the difficulty of cleaning and drying the fasteners in the later stage.

[0034] The conveyor 3 is an enclosed Z-shaped conveyor;

[0035] Embodiment 2:

[0036] Refer to Figures 2-6, which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a feed hopper 14 is fixedly installed on one side of the top of the protective cover 4, and a mounting seat 15 is fixedly installed on the other side of the top of the protective cover 4. A cylinder 16 is fixedly installed on the top of the mounting seat 15, and the cylinder 16 is connected to an external air pump through a pipeline. Based on this, the setting of the cylinder 16 is a necessary condition for realizing the lifting of the pull rod 13. A drain pipe 19 is fixedly installed at the bottom of the separation barrel 9 located between the separation barrel 9 and the first annular partition 10, and a drain pipe 20 is fixedly installed at the bottom of the separation barrel 9 located between the first annular partition 10 and the second annular partition 24. Solenoid valves are fixedly installed at the ends of the drain pipe 19 and the drain pipe 20 away from the separation barrel 9. Based on this, the drain pipe 19 and the drain pipe 20 are respectively arranged at the bottom of the separation barrel 9 at the outer and inner positions of the first annular partition 10, so as to discharge and collect the separated oil and water. A plurality of oil overflow ports 17 are opened on the inner side of the first annular partition 10, and a liquid level sensor 18 is also fixedly installed on the inner side of the first annular partition 10 above the oil overflow port 17. The liquid level sensor 18 is electrically connected to an external controller through a connecting wire. Based on this, the first annular partition 10 and the second annular partition 24 are arranged in the separation barrel 9, and the oil and water are separated by using the principle that oil floats on water, and the liquid level in the separation barrel 9 between the first annular partition 10 and the second annular partition 24 is ensured by cooperating with the liquid level sensor 18. A plurality of blanking ports 21 are opened at the lower position inside the screen 11. The sealing ring 12 is inserted and installed between the screen 11 and the conical seat 8 and is located above the blanking port 21. A fixing seat 22 is fixedly installed on the outer side of the pull rod 13, and a stabilizing rod 23 is threadedly connected to the fixing seat 22. The bottom of the pull rod 13 is fixedly installed on the sealing ring 12, and the top of the pull rod 13 passes through the top of the protective cover 4 and is fixedly connected to the output end of the cylinder 16. The top of the pull rod 13 also passes through the through hole at the top of the protective cover 4 and extends to the upper position of the protective cover 4. Based on this, after the oil and water on the outer surface of the fastener are separated by driving the conical seat 8 and the screen 11 to rotate by the motor 6, the sealing ring 12 can be lifted by cooperating with the cylinder 16 and the pull rod 13, so as to discharge the fastener through the blanking port 21 and the second annular partition 24.

[0037] It should be noted that the present utility model is a centrifugal oil-water separation type cold heading machine for fasteners. After the fasteners processed in the cold heading machine 1 are temporarily stored in the storage bin on one side of the cold heading machine 1, the conveyor 3 can be started through the controller. Then, the conveyor 3 can regularly convey the fasteners and part of the oil-water mixture in the storage bin on one side of the cold heading machine 1 into the feed hopper 14, and enable the fasteners and the oil-water mixture to enter the separation barrel 9 through the feed hopper 14. Then, the fasteners are intercepted by the screen 11, while the oil-water mixture enters the separation barrel 9 located between the first annular partition 10 and the second annular partition 24 through the screen 11, so that the oil floats on the water surface and flows into the cavity between the first annular partition 10 and the separation barrel 9 through a plurality of oil overflow ports 17. And the liquid level sensor 18 is used to monitor the liquid level in the cavity between the first annular partition 0, the first annular partition 10, and the second annular partition 24, and the solenoid valve at one end of the drain pipe 20 is used to control the liquid level in the separation barrel 9, the first annular partition 10, and the second annular partition 24, so as to ensure that the separated oil can flow into the cavity between the separation barrel 9 and the first annular partition 10 through the oil overflow port 17.

[0038] After a certain amount of fasteners are conveyed and placed in the screen 11, the oil-water separator 2 can be closed and the motor 6 can be started. Then, the motor 6 drives the rotating shaft 7 and the conical seat 8 to rotate, and the conical seat 8 drives the screen 11 to rotate. Thus, the centrifugal force generated by the screen 11 driving the fasteners to rotate throws the oil-water mixture attached to the outer surface of the fasteners into the cavity formed by the separation barrel 9, the first annular partition 10, and the second annular partition 24. After the oil-water separation treatment of the fasteners is completed, the motor 6 is closed, and the cylinder 16 is controlled by controlling an external pump station. Then, the output end of the cylinder 16 lifts the pull rod 13, and the pull rod 13 drives the sealing ring 12 and the stability rod 23 to move upward synchronously. Then, the pull rod 13 moves upward in the screen 11 and exposes a plurality of blanking ports 21, so that the fasteners in the screen 11 are discharged and collected through the blanking ports 21 and the second annular partition 24.
