Description

Technical Field

[0001] This utility model relates to the field of cold heading dies, and in particular to an automatic lubrication device for cold heading dies. Background Technology

[0002] Cold heading dies are used on cold heading machines. Through the cooperation of the upper and lower half dies and the die core, the metal billet undergoes plastic deformation at room temperature to obtain parts of the required shape and size. Lubrication plays a crucial role in the die processing and forming process. Lubricant can form a thin film between the die and the workpiece, preventing them from directly contacting each other, thereby reducing friction and significantly reducing wear on the die surface, and extending the service life of the die.

[0003] According to patent publication number CN118527563A, this invention discloses a self-lubricating stamping die, including a base, a fixed die on the top of the base, a support frame fixedly connected to the top of the base, a press mounted on the support frame, a mounting plate fixedly connected to the output shaft end of the press, a moving die mounted on the mounting plate, and an oiling mechanism on one side of the base. The oiling mechanism includes an oiling frame with an oiling cavity. Multiple nozzles are rotatably connected to both sides of the oiling cavity, and the multiple nozzles on the same side are connected by transmission. By setting up the oiling mechanism, the press drives the piston to move, which draws oil from the oil tank into the oil cylinder and then delivers the oil to the nozzles, while simultaneously driving the nozzles to rotate, thereby increasing the oiling area and oiling uniformity. This allows for simultaneous oiling of both sides of the workpiece, eliminating the need for frequent oiling operations by workers, effectively reducing labor intensity and improving ease of use.

[0004] However, due to the large size of the nozzles and oil cylinders in the above technologies, when cold heading dies are used for machining small precision parts, the nozzles cannot be installed in the small mold cavities. In addition, the above technologies can only lubricate two sides of the workpiece. When the mold is irregularly shaped, it is impossible to lubricate the entire workpiece, thus reducing the quality of lubrication. Utility Model Content
