Description

Technical Field

[0001] The utility model relates to the technical field of oil plug processing, in particular to a square oil plug non-waste cold heading forming device. Background Art

[0002] Cold heading is a forging method that uses a die to upset metal bars at room temperature. It is usually used to make the heads of screws, bolts, rivets, etc. The bars are automatically fed to a certain degree by a feeding mechanism, and the cutting mechanism cuts them into blanks, which are then sent to the accumulation, pressing and punching stations in sequence by the clamp conveying mechanism for cold heading, with high production efficiency.

[0003] After searching, the application with patent publication number CN212917476U discloses a square oil plug waste-free cold heading forming device, including a mother mold and a rear-drag large screw. A feed rod is passed through the mother mold, and the feed rod extends to the inside of the rear-drag large screw. A connecting plate is welded and fixed on one side of the mother mold, and a fixing rod is welded and fixed above the connecting plate. A stabilizing block is arranged above the fixing rod, and the stabilizing block is snap-connected with the feed rod. A starting connecting rod is passed through the rear-drag large screw, which can prevent the feed rod from shifting when moving, and prevent bending and breaking, which causes waste of resources.

[0004] However, due to the setting of the mother mold and the large rear screw, the specifications of the mother mold are fixed, resulting in fixed specifications of the material rod, so that only one specification of oil plug can be processed, which has low practicality. At the same time, due to the setting of the stabilizing block and the fixing rod, it can be ensured that the raw material rod does not shift, but the friction between the raw material rod and the stabilizing block is large, and the raw material rod is prone to wear during movement, which affects the life of the raw material rod and causes waste of resources.

[0005] Therefore, we proposed a waste-free cold heading forming device for square oil plugs. Utility Model Content
