[0031] Reference Figure 1-Figure 3 According to an embodiment of the utility model, an oil filter device in a cold heading machine includes an oil tank 12 arranged at the lower side of the cold heading machine, an oil filter pool 13 with an opening facing upward is arranged in the oil tank 12, and an oil outlet in the cold heading machine faces the oil filter pool 13.

[0032] In this embodiment, a coarse filtration section and a fine filtration section are provided in the oil tank 12 .

[0033] The coarse filtration link is designed as follows: a filter screen 14 is laid in the oil filter pool 13, a scraper plate 15 is also slidably connected to the oil tank 12, and a push plate mechanism 101 is provided in the oil tank 12 to drive the scraper plate 15 to move left and right. When the scraper plate 15 moves left and right, the waste filtered out by the filter screen 14 can be swept away to avoid clogging of the filter screen 14.

[0034] In addition, a mounting groove 23 is respectively provided on the left and right sides of the oil tank 12, and a chip box 16 is hung on the mounting groove 23, and the chip box 16 is composed of a hanging plate 91 and a box body 92. A deep groove is provided in the lower side of the mounting groove 23, and the hanging plate 91 is attached to the lower side of the mounting groove 23 and extends into the deep groove and locks the position of the box body 92. The upper side of the hanging plate 91 is inclined downward in the direction away from the filter screen 14, and the upper side of the hanging plate 91 is connected with the upper side of the box body 92. The waste swept away by the scraper plate 15 can enter the box body 92 along the hanging plate 91, and the staff can take out the chip box 16 and clean the waste therein.

[0035] In addition, a rotating shaft is rotatably connected to the side of the mounting groove 23, and the rotating shaft is also connected to the side of the mounting groove 23 through a torsion spring. A baffle 17 is fixed on the rotating shaft, and a transversely extending extension plate 18 is fixed on the side of the mounting groove 23. The upper side of the extension plate 18 is connected to the upper side of the oil tank 12, and the baffle 17 abuts against the extension plate 18 and tilts upward, and the baffle 17 can be pressed by the hanging plate 91 to stick to the vertical side of the mounting groove 23;

[0036] When the baffle 17 is pressed by the hanging plate 91, the baffle 17 does not work and is only used to clamp the hanging plate 91 and the box body 92. When the chip box 16 needs to be taken out for cleaning, the baffle 17 will be attached to the extension plate 18 under the action of the torsion spring and will be in an inclined state. At this time, the debris swept out by the scraper plate 15 will be retained on the baffle 17 in the inclined state and blocked by the extension plate 18 to prevent it from falling. Afterwards, when the chip box 16 is installed back into the mounting groove 23, the baffle 17 can be pressed and tilted, so that the waste temporarily stored on the baffle 17 falls into the box body 92.

[0037] In this embodiment, the push plate mechanism 101 includes a side groove arranged in the oil tank 12, a reciprocating screw 19 is rotatably connected in the side groove, the scraper plate 15 is connected to the reciprocating screw 19, and a motor 32 for driving the reciprocating screw 19 is arranged on the oil tank 12. When the motor 32 is powered on, it drives the reciprocating screw 19 to rotate, thereby making the scraper plate 15 periodically move left and right to clean the inclined surface 20. At the same time, in order to ensure the stable movement of the scraper plate 14, two sliding rods penetrating the scraper plate 14 are also arranged in the side groove;

[0038] In this embodiment, the motor 32 is fixed to the front side of the oil tank 12, and the output shaft in the motor 32 is connected to the reciprocating screw 19 through a bevel gear set.

[0039] In order to prevent the oil that cannot be filtered in time from leaking out, the upper side of the filter 14 is lower than the upper side of the oil tank 12, and in order to facilitate the waste on the upper side of the filter 14 to be pushed out by the scraper 15, the left and right sides of the oil filter pool 13 are connected to the upper side of the oil tank 12 through an inclined surface 20, and the upper side of the filter 14 is at the same height as the lower edge of the inclined surface 20.

[0040] In order to enable the scraper plate 15 to pass through the inclined surface 20 smoothly to sweep the waste into the box body 92, the scraper plate 15 is designed as follows: the scraper plate 15 is composed of a fixed plate 81 and a telescopic plate 82, and a telescopic groove is provided in the fixed plate 81, and the telescopic plate 82 is connected to the telescopic groove by sliding up and down, and the telescopic plate 82 is attached to the filter 14. In order to facilitate the rebound of the telescopic plate 82, the telescopic plate 82 is also connected to the upper side of the spring groove through a spring.

[0041] The lower side surface of the fixed plate 81 located on the upper side of the oil filter pool 13 is higher than the upper edge of the inclined surface 20, and the reciprocating screw 19 is connected to the fixed plate 81. When the reciprocating screw 19 drives the scraper plate 15 to move left and right, the telescopic plate 82 will pass through the filter 14, the inclined surface 20 and the upper side surface of the oil tank 12 respectively to clean the waste on the filter 14 into the box body 92.

[0042] The fine filtration link is designed as follows: a boss is provided on the lower side of the oil tank 12, and a filter 21 is screwed on the boss; a liquid inlet hole is provided on the lower side of the oil filter pool 13, which passes downward through the boss and is connected to the filter 21; a pump 31 is also provided on the side of the oil tank 12 for extracting the oil in the oil filter pool 13 that passes through the filter 14 and the filter 21 and pumping it into the cold heading machine; a liquid outlet hole 22 connected to the filter 21 and the pump 31 is provided on the lower side of the boss; the lower side of the oil filter pool 13 is conical and tilted downward toward the liquid inlet hole to facilitate oil circulation.

[0043] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
