Description

Technical Field

[0001] The utility model relates to the technical field of grease adders, and more specifically, to an automatic grease adder. Background Art

[0002] The automatic greaser runs a small reducer according to the time stored in the microprocessor, driving the worm gear inside the pump to suck or spray out the grease in the container through the reciprocating motion of the vertical piston, thereby strengthening the maintenance of the equipment. As the shape of automobiles becomes more and more varied, the mold requires more wedges to achieve the shape, and the working guide parts of the wedge must be lubricated with grease to ensure the smooth operation of the wedge;

[0003] The existing automatic greaser is difficult to form a one-to-one correspondence with the number of punches, which easily causes a waste of grease. In addition, the existing automatic greaser is not convenient for timely replenishing grease. Insufficient grease can easily cause damage to the guide plate, which in turn affects the quality of parts.

[0004] After searching, a Chinese patent with publication number CN214663621U discloses an automatic greaser for cold stamping dies. Every time the press makes a stamping action, the air pressure generated will cause the transparent grease container to discharge oil, so that the device can form a one-to-one correspondence with the number of stampings, avoiding the waste of grease. At the same time, the oil output of the transparent grease container in the working state can be controlled by the oil reduction valve, further saving grease. In addition, the staff can observe the amount of grease in time. When the oil amount is insufficient, the transparent grease container can be refueled through the oil filling nozzle, so that the device is convenient for timely replenishing grease, effectively reducing the risk of damage to the mold due to insufficient grease, and ensuring the quality of parts.

[0005] However, when this structure is actually used, when the amount of oil in the see-through grease container is insufficient, the staff will refill the see-through grease container with grease through the oiling nozzle, which requires the staff to observe the amount of oil in the see-through grease container all the time, and the staff will not be reminded to refill when the amount of oil in the see-through grease container is insufficient, which may easily lead to the staff not observing the amount of oil in the see-through grease container, resulting in untimely refilling, affecting the use effect, and wasting time and effort.
