Description

Technical Field

[0001] This utility model relates to the field of steel wire drawing technology, and more specifically, to a steel wire drawing device. Background Technology

[0002] In the wire drawing process, pressure dies and working dies are essential. The primary purpose of these dies is to gradually shape the wire to the desired dimensions. During wire drawing, the die forces the wire through, compressing its cross-sectional area to achieve the required shape and size. However, currently available pressure dies and working dies lack a limiting structure, leading to misalignment and negatively impacting the wire drawing quality. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a steel wire drawing device that can ensure that the pressure die and the working die are always in a coaxial state, that is, to avoid misalignment between the pressure die and the working die, thereby ensuring the drawing quality of the steel wire.

[0004] This utility model provides a steel wire drawing device, including a mold box and a drawing die for drawing steel wire; the drawing die is installed in the inner cavity of the mold box and is used for the steel wire to pass through axially and for drawing the steel wire; the drawing die includes a pressure die and a working die; the working die and the pressure die are coaxially arranged, the pressure die has an annular cavity at one end facing the working die, and the working die has an annular boss on the side facing the pressure die, the annular boss is inserted into the annular cavity, and the outer peripheral wall of the annular boss is in contact with the inner peripheral wall of the annular cavity.

[0005] With the above-described structure, after the annular boss and the annular cavity are fitted together, the outer peripheral wall of the annular boss is in contact with the inner peripheral wall of the annular cavity, thus ensuring that the pressure die and the working die are always in a coaxial state. This avoids misalignment between the pressure die and the working die, thereby ensuring the quality of wire drawing.

[0006] In one possible implementation, an annular guide surface is provided on the inner wall of the opening end of the annular cavity. The annular guide surface is used to cooperate with the outer peripheral wall of the annular boss to guide it so that the annular boss can be inserted into the annular cavity. By providing an annular guide surface on the inner wall of the opening end of the annular cavity, when the annular boss and the annular cavity are engaged, the annular guide surface can cooperate with the outer peripheral wall of the annular boss to guide it so that the annular boss can be inserted into the annular cavity, which facilitates the engagement of the annular boss and the annular cavity.

[0007] In one possible implementation, an annular conical surface is provided on the outer peripheral wall of the outer end of the annular boss. The annular conical surface is used to guide and cooperate with the inner peripheral wall of the annular cavity so that the annular boss can be inserted into the annular cavity. By providing an annular conical surface on the outer peripheral wall of the outer end of the annular boss, when the annular boss and the annular cavity are engaged, the annular conical surface can cooperate and guide with the inner peripheral wall of the annular cavity so that the annular boss can be inserted into the annular cavity, which can facilitate the engagement and insertion of the annular boss and the annular cavity.

[0008] In one possible implementation, a cooling water inlet communicating with the inner cavity is provided on the front side of the mold box, and a water inlet connector is connected to the outer end of the cooling water inlet; a cooling water outlet communicating with the inner cavity is provided on the rear side of the mold box, and a water outlet connector is connected to the outer end of the cooling water outlet; by adopting this structure, after the water inlet connector is connected to the outlet end of the cooling water circulation device and the water outlet connector is connected to the return end of the cooling water circulation device, the cooling water can continuously flow through the inner cavity of the mold box, thereby achieving continuous cooling of the wire drawing die, that is, avoiding overheating of the wire drawing die, so as to ensure the wire drawing effect of the wire drawing die on the outer surface of the steel wire.

[0009] In one possible embodiment, the wire drawing die further includes a copper washer embedded in an annular cavity. The copper washer is pressed against the inner end of the annular cavity by an annular boss. The copper washer is tightly sealed to both the inner end of the annular cavity and the outer end of the annular boss. With this structure, after the copper washer is pressed against the inner end of the annular cavity by the annular boss, due to the high flexibility of the copper washer, it can deform and tightly seal against both the inner end of the annular cavity and the outer end of the annular boss. Thus, under the action of the copper washer, cooling water in the inner cavity can be prevented from entering the mold cavity between the pressure die and the working die, thereby keeping the steel wire dry.
