[0019] The present invention provides Figure 1-8The cooling oil impurity separation device for a bolt cold heading machine shown in the figure comprises an oil tank 1, a filtering mechanism is installed on the oil tank 1, an impurity cleaning mechanism is installed on the oil tank 1, the filtering mechanism comprises a recovery box 2 installed on the upper end of the surface of both sides of the oil tank 1, a recovery pipe 3 is installed at the lower end of the recovery box 2, one end of the recovery pipe 3 extends into the oil tank 1, a winder 4 is installed on the recovery box 2, a filter screen 5 is placed in the oil tank 1, both ends of the filter screen 5 are wound on the winder 4, a plurality of rotating rollers 6 are installed in the oil tank 1, and the filter screen 5 is rotated from the rotating roller 6. The impurity cleaning mechanism includes a driving frame 7 installed on one side above the winder 4, and a cleaning pipe 8 is installed on the driving frame 7. The driving frame 7 can drive the cleaning pipe 8 to rotate. The driving frame 7 can drive the cleaning pipe 8 to move as the thickness of the filter screen 5 on the winder 4 increases or decreases. The cleaning pipe 8 can attract metal impurities on the filter screen 5 through magnetic force. A waste box 9 is installed on the cleaning pipe 8. When the cleaning pipe 8 rotates, the metal impurities can fall into the waste box 9. The waste box 9 can intercept the metal impurities and cause the cooling oil to fall. The process of this device separating impurities in the cooling oil is as follows: Under normal circumstances, the used cooling oil falls from above into the oil tank 1, and the filter screen 5 allows the cooling oil to pass through and intercepts the impurities. After using it for a period of time, the winder 4 is started to run forward, and the filter screen 5 can be reeled up by the winder 4, and the filter screen 5 can be replaced. When the filter screen 5 is reeled up, the cleaning pipe 8 is driven to rotate by the driving frame 7, and the cleaning pipe 8 can attract the impurities on the filter screen 5. The thickness of the winder 4 will increase when the filter screen 5 is reeled up, and the driving frame 7 can drive the cleaning pipe 8 to move, so that there is a certain gap between the cleaning pipe 8 and the filter screen 5, which can not only absorb the impurities on the filter screen 5, but also will not block the winder 4 from reeling in the filter screen 5 and the cleaning pipe 8. After driving the impurities to rotate a certain angle, the impurities can fall into the waste box 9 under the action of gravity and be collected. After the filter 5 is replaced, the impurities can continue to be filtered. After a period of collection, the winder 4 is started to run in reverse, the filter 5 can be wound to the other side, and the impurities on the filter 5 can be collected through the cleaning pipe 8. By running the winder 4 forward and reverse, the filter 5 can be recycled, and the impurities on the filter 5 can be collected. A small amount of cooling oil contained in the impurities falling into the waste box 9 can fall into the oil tank 1. The cooling oil remaining on the filter 5 can fall into the recovery box 2 after being wound up by the winder 4, and then return to the oil tank 1 through the recovery pipe 3, so that the cooling oil can be recycled.

The two ends of the filter screen 5 are respectively wound on the winding shaft 10 above the recycling box 2, and a rotating motor 13 is installed on the surface of one side of the oil tank 1. The rotating end of the rotating motor 13 is installed with a first one-way bearing 14, and a first sprocket 15 is installed on the outside of the first one-way bearing 14.

A fourth sprocket 20 is installed on the other winding shaft 10, and the third sprocket 19 and the fourth sprocket 20 are connected by a second chain 21; The process of the winder 4 winding up the filter 5 is as follows: when the filter 5 needs to be wound up, the rotating motor 13 is started to rotate forward, and the rotating end of the rotating motor 13 can rotate in the second one-way bearing 18, and will not drive the second one-way bearing 18 to rotate. The rotating motor 13 can drive the first one-way bearing 14 and the first sprocket 15 to rotate. The first sprocket 15 and the second sprocket 16 are connected by a first chain 17, which can drive the second sprocket 16 and a winding shaft 10 to rotate. This winding shaft 10 can wind up the filter 5, and the other winding shaft 10 can follow the rotation under the involvement of the filter 5 and release the filter 5, which makes it easy to replace the filter 5. After using it for a period of time, the filter 5 needs to be rewound again. To replace, start the rotating motor 13 and reverse. The rotating end of the rotating motor 13 can rotate in the first one-way bearing 15, and will not drive the first one-way bearing 15 to rotate. The rotating motor 13 can drive the second one-way bearing 18 and the third sprocket 19 to rotate. The third sprocket 19 and the fourth sprocket 20 are connected by the second chain 21, which can drive the fourth sprocket 20 and another winding shaft 10 to rotate. The second winding shaft 10 can retract the filter screen 5. The first winding shaft 10 can follow the rotation under the traction of the filter screen 5 and release the filter screen 5, which can facilitate the replacement of the filter screen 5. By alternating forward and reverse rotation of the rotating motor 13, the filtering position of the filter screen 5 can be replaced, which can facilitate the interception of impurities.

Therefore, when the winding shaft 10 rotates one circle to retract or release the filter screen 5 to change the thickness, the lifting screw 25 and the threaded sleeve 24 can be moved upward or downward. Move the thickness of the filter screen 5 by one grid, so as to ensure the thickness between the cleaning tube 8 and the filter screen 5. When the threaded sleeve 24 rotates, the first gear 36 can be driven to rotate, and the first gear 36 and the second gear 37 are engaged, thereby driving the second gear 37 and the rotating column 30 to rotate. The rotating column 30 can drive the square transmission rod 32, the cylinder 33, and the third bevel gear 38 to rotate through the square groove 31.
