Embodiment Construction

[0038] An oil-free self-lubricating hinge provided in this specific embodiment is as follows: figure 1 As shown, it includes a mandrel 1 and two blades 2, 3, and each of the blades 2, 3 has at least one bearing 4 integrally formed with the blades 2, 3, and the mandrel 1 passes through the bearing 4 In this way, the two blades 2, 3 are rotatably connected. The difference with the prior art is that, as figure 2 As shown, the inner wall of the bearing 4 is also provided with a self-lubricating inner lining layer 5 , and the mandrel 1 is actually penetrated in the self-lubricating inner lining layer 5 .

[0039] This specific embodiment accordingly provides a method for manufacturing an oil-free self-lubricating hinge, which is used to manufacture the aforementioned oil-free self-lubricating hinge. The manufacturing method includes the following steps:

[0040] S1), make the blade blank: manufacture such as with the method for stamping or casting Figures 3 to 6 Shown are blad...

Abstract

The invention discloses an oilless self-lubricating hinge and a manufacturing method thereof. A self-lubricating lining layer is arranged on the inner wall of a bearing of the hinge, and a mandrel penetrates through the self-lubricating lining layer. According to the manufacturing method of the oilless self-lubricating hinge, after a blade blank is manufactured, injection molding is performed on the blade blank on the inner wall of the bearing by adopting plastic with high hardness, high rigidity, high wear resistance and good self-lubricating performance so as to form the self-lubricating lining layer, and finally, a blade of the self-lubricating lining layer after injection molding is assembled with the mandrel so as to form the oilless self-lubricating hinge. According to the oilless self-lubricating hinge which is manufactured by adopting the manufacturing method of the technical scheme, the self-lubricating lining layer is formed in the bearing by injection molding, therefore, themetal mandrel cannot make direct contact with the metal bearing so as not to wear, thus, lubricating oil does not need to be added, so that the problem of dirty caused by oil leakage is avoided, andadditionally, the self-lubricating lining layer has good self-lubricating performance, so that the service life of the hinge is long.

Description

technical field [0001] The invention relates to the technical field of hardware accessories, in particular to a hinge, in particular to an oil-free self-lubricating hinge. Background technique [0002] Hinge is also known as hinge, and its official name is hinge. Often composed of two folds, it is a part that connects two parts of an object and enables it to move. Friends who have carefully observed the bronze chariots and horses of the Qinling Mausoleum may remember the hinges and hinges at the junction of the No. 2 bronze carriage door and the compartment, which are completely similar to modern building door and window hinges in terms of shape and structure. It marks that our ancestors invented and used hinges as early as 2200 years ago. Moreover, we also found that the range of hinges used by the Qin people was by no means limited to copper chariots and horses. Near the chariots in Pit No. 2 and Pit No. 1 of the Terracotta Warriors, archaeologists found an equally cons...
