Embodiment Construction

[0008] Open a large annular groove (6) at the bottom of the die (2), fill the annular groove with wool felt (2), the large annular groove (2) is the same as the oil pipe (4), and set an oil pool at the end of the oil pipe (4) (5), at the die opening of the die (3), several small annular oil grooves (7) are made, and the large annular groove (6) is communicated with the small annular oil groove (7) with an oil hole (8), so that After lubricating oil is added into the oil pool (5), good lubrication can be formed to the workpiece and the die through the above-mentioned passage.

Abstract

The invention discloses a novel self-lubricating female die, and belongs to the technical field of dies. The bottom of the female die is provided with a large annular groove in which felted wools are filled; an orifice of the female die is provided with a plurality of small annular oil grooves, and the large annular groove and the small annular oil grooves are communicated through oil holes; and an external oil pool is communicated with the large annular groove filled with the felted wools through an oil pipe, so oil in the external oil pool well lubricates workpieces and the female die through the passages. The novel self-lubricating female die has the advantages of overcoming the shortcoming of large workload which is generated by a method of pre-oiling blank materials during the stretching production and overcoming the shortcoming of manual nonuniform oiling.

Description

technical field [0001] The invention relates to a mold, in particular to a novel self-lubricating concave mold, which belongs to the technical field of molds. Background technique [0002] In the stretching production of 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 new type of self-lubricating die, which overcomes the disadvantage of large amount of labor in the method of pre-oiling the rough material in stretching production, and at the same time, als...
