Embodiment Construction

[0008] A large annular groove (6) is opened at the bottom of the die base (1), and wool felt (2) is filled in the large annular groove (6). The large annular groove (6) is the same as the oil pipe (4), and the oil pipe (4) An oil pool (5) is arranged at the end, and several small annular oil grooves (7) are made at the die opening of the die (3), and the large annular groove (6) and the small annular oil groove ( 7) communicate, so that after lubricating oil is added into the oil pool (5), it can pass through the above-mentioned passages to effectively coat the large die panel (9) and the small die panel (10) with a layer of oil, and the workpiece and the The die forms a good lubrication.

Abstract

The invention relates to a self-lubricating steel plate concave die. The bottom of a pedestal of the concave die is provided with a large circular groove. The large circular groove is filled with felted wool. The large circular groove is communicated with an oil tube. The end part of the oil tube is provided with an oil pool. The concave die orifice position of the concave die is provided with a plurality of small circular grooves. The large circular groove is communicated with the small circular grooves by oil holes. Therefore, when the oil pool is added with lubricating oil, a large concave die panel and a small concave die panel can be effectively coated with one layer of oil by the channels so as to form excellent lubrication for the workpieces and the concave die. The invention has the advantages of overcoming the defect of larger labor capacity of the method for coating the oil on the blank material in advance in the steel plate tensioning production, and at the same time also overcoming the defect of non-uniform coating in the process of manually coating the oil.

Description

technical field [0001] The invention relates to a mold, in particular to a self-lubricating steel plate concave mold, which belongs to the technical field of mechanical molds. Background technique [0002] At present: In the stretching production of steel plate cold stamping, in order to reduce the resistance of stretching and facilitate metal forming, people often apply a layer of oil on the blank material in advance. Although the oiling method is simple and easy to implement, the labor load is also very heavy when the product batch is large and the product blank material is large. In addition, the artificial oiling method also has uneven application, which causes stretching. Uneven local stress can easily cause product quality problems. Contents of the invention [0003] The purpose of the present invention is to provide a kind of: overcome the defect that the amount of labor is relatively large in the method of pre-oiling the rough material in the stretching production...
