Description

Technical Field

[0001] This utility model belongs to the field of fastener technology, and in particular relates to a fastener cold heading forming receiving mechanism. Background Technology

[0002] Cold heading machines are key equipment for mass production of fasteners. During the cold heading process, the machine oil in the machine's oil tank lubricates the mold and the surface of the fastener blank to protect the mold and facilitate the stretching of the steel. Therefore, after cold heading and before tapping, the machine oil on the fastener blank needs to be removed and recycled to reduce waste. Currently, the method of blowing off the machine oil from the fastener surface with an air gun has problems such as easy oil evaporation, affecting the air quality in the workshop, and incomplete cleaning of the lower surface of the fastener or fasteners stacked at the bottom. Summary of the Invention

The bracket 11 is fixedly installed on the base 1. The four support columns 12 are rectangularly distributed, with their lower ends and middle parts fixedly connected to the base 1 and the bracket 11, respectively. The rotating shaft 21 has two ends... The filter cartridge 31 is rotatably mounted on the bracket 11. The first drive motor 2 is fixedly mounted on the bracket 11, and the output shaft of the first drive motor 2 is drively connected to the rotating shaft 21. The carrier plate 22 is fixedly mounted on the rotating shaft 21. The second drive motor 3 is fixedly mounted on the carrier plate 22. The bottom central shaft of the filter cartridge 31 is rotatably mounted on the carrier plate 22, and the output shaft of the second drive motor 3 is drively connected to the bottom central shaft of the filter cartridge 31. The collection bucket 32 ​​is fixedly mounted on the carrier plate 22, and the filter cartridge 31 is located inside the collection bucket 32. The bottom has a pipe connector 34. The connecting plate 5 is fixedly installed on the top of the support column 12. The top of the support column 12 is provided with a guide hole. The lower end of the guide rod 6 is slidably installed in the guide hole of the support column 12. The cylinder body of the telescopic cylinder 4 is fixedly installed on the base 1. The transfer barrel 7 is fixedly installed on the top of the guide rod 6. A spring 61 is sleeved on the guide rod 6. The upper and lower ends of the spring 61 act on the transfer barrel 7 and the connecting plate 5, respectively. The upper end of the anti-detachment rod 9 is fixedly installed on the bottom of the transfer barrel 7, and the lower end of the anti-detachment rod 9 is slidably installed. Inside the connecting plate 5, a first stop ring 91 is fixedly sleeved at the bottom of the anti-detachment rod 9. A discharge port is provided on the transfer barrel 7. The guide bracket 72 is obliquely fixedly installed at the discharge port of the transfer barrel 7. The limiting plate 71 is slidably installed inside the transfer barrel 7. A second stop ring 73 for supporting the limiting plate 71 is also fixedly installed inside the transfer barrel 7. The first connecting rod 8 and the second connecting rod 10 are fixedly connected. The upper end of the first connecting rod 8 is fixedly connected to the limiting plate 71, and the lower end of the second connecting rod 10 is fixedly connected to the piston rod of the telescopic cylinder 4.

[0014] The collection tank 32 is provided with a flow collector plate 33, and the flow collector plate 33 is provided with a flow collection hole 331 that is connected to the pipeline connector 34. The bottom central shaft of the filter cartridge 31 is rotatably and sealedly installed with the flow collector plate 33. Through the structure of the flow collector plate 33, which is recessed to the flow collection hole 331 on the top surface, the oil accumulation in the tank 32 can be collected.

[0015] The pipe connector 34 is connected to the collection box via a flexible hose. When the rotating shaft 21 drives the carrier plate 22 to rotate, the flexible hose does not cause any restriction.

[0016] The limiting plate 71 is set with a 40° inclined structure with the left side lower and the right side higher, so that the fasteners in the transfer barrel 7 can slide into the filter cartridge 31 through the guide bracket 72.

[0017] Cold-forged fasteners fall into the transfer drum 7. At this time, the piston rod of the telescopic cylinder 4 extends upward, pushing the assembly of the first connecting rod 8, the second connecting rod 10, and the limiting plate 71 upward. The limiting plate 71 blocks the discharge port of the transfer drum 7. Under the action of the spring 61, the assembly of the transfer drum 7 and the guide bracket 72 moves upward, preventing the guide bracket 72 from contacting the filter cartridge 31 and affecting its rotation. When the transfer drum 7 is filled with more than 30%-50% fasteners, the telescopic cylinder 4 pulls the limiting plate 71 downward. The left end of the limiting plate 71 is located below the discharge port. At this time, the fasteners in the transfer drum 7 slide into the filter cartridge 31 through the discharge port and the guide bracket 72. After the limiting plate 71 contacts the second stop ring 73... The piston rod continues to retract, pulling the transfer drum 7 to compress the spring 6 and move it downwards, so that the bottom of the guide bracket 72 is close to the center of the top opening of the filter cylinder 31, to prevent the fasteners from flying out of the filter cylinder 31. Then the piston rod of the telescopic cylinder 4 extends upwards to reset, and the limit plate 71 continues to block the discharge port. The second drive motor 3 is started to drive the filter cylinder 31 to centrifuge the oil on the surface of the fasteners. Under the action of centrifugal force, the oil enters the collection bucket 32 ​​and is discharged through the pipe joint 34 and the hose. After the centrifugation is completed, the second drive motor 3 stops rotating, and the first drive motor 2 is started to drive the rotating shaft 21, the carrier plate 22 and the filter cylinder 31 to rotate 120°-160° to tilt and collect the fasteners.
