Description

Technical Field

[0001] This utility model belongs to the field of drawing die technology, specifically relating to a steel wire drawing die. Background Technology

[0002] Drawing dies are industrial tools used for the plastic forming of metals. They achieve precision forming by applying tensile force to metal materials. Wire drawing dies are special tools used for the cold forming of steel wires. They apply tensile force to the steel wire through the die hole, compressing its cross-sectional area to achieve plastic deformation and obtain the target size and shape.

[0003] Currently, existing wire drawing dies are cylindrical structures with corresponding die holes inside. When the die holes are deformed, the entire die needs to be replaced, as it cannot be disassembled and replaced individually, resulting in unnecessary waste. Therefore, a wire drawing die is proposed, which sets a drawing die with a die groove between the lower die shell and the upper die shell. When the die groove is damaged, the drawing die can be disassembled and replaced. Summary of the Invention

[0004] In view of the shortcomings of the above background technology, the purpose of this utility model is to provide a wire drawing die, which sets a drawing die with a die groove between the lower die shell and the upper die shell. If the die groove is damaged, the drawing die can be disassembled and replaced.

[0005] The purpose of this utility model is to solve the above-mentioned technical problems as follows: A wire drawing die includes a lower die shell and an upper die shell. The upper die shell is disposed on top of the lower die shell. Placement grooves are provided on the top surface of the lower die shell and the bottom surface of the upper die shell. A drawing die is disposed between the lower die shell and the upper die shell. A die groove is provided through one end of the drawing die. The top of the upper mold shell is equipped with a lubrication component, which includes a transparent oil storage tank. The bottom of the transparent oil storage tank is connected to a valve through a pipe, and the bottom of the valve is connected to a connecting pipe through a threaded groove.

[0006] By adopting the above technical solution, the lower mold shell and the upper mold shell are closed and locked together by the placement groove. The mold groove inside the drawing mold can be disassembled and replaced after deformation. The valve is opened to allow the lubricating oil in the transparent oil storage tank to drip into the closed lower mold shell and the upper mold shell.

[0007] Based on the above scheme and as a preferred option: limit grooves are provided at equal intervals on the inner side of the placement groove, and limit strips corresponding to the limit grooves are provided at equal intervals on the outer side of the drawing die.

[0008] Based on the above scheme and as a preferred option: threaded holes are equidistantly opened on both sides of the lower mold shell, and fixing bolts corresponding to the threaded holes are equidistantly arranged on both sides of the upper mold shell.

[0009] Based on the above scheme and as a preferred option: the top of the transparent oil storage tank is provided with an oil filling port, and a support rod is fixed between the transparent oil storage tank and the upper mold shell by bolts.

[0010] Based on the above scheme and as a preferred option: a through hole is provided at the top of the upper mold shell, and the bottom end of the connecting pipe is connected to the top of the through hole.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the lower mold shell and the upper mold shell are made of stainless steel, and the drawing die is made of tungsten-cobalt alloy.

[0012] The outstanding and beneficial technical effects of this utility model compared to the prior art are: This utility model discloses a wire drawing die. After the lower die shell and the upper die shell are closed, the drawing die is fixed by the placement groove. Multiple limiting strips on the outside of the drawing die engage with the limiting groove to prevent the drawing die from rotating in the placement groove. The fixing bolts are screwed into the threaded holes to fix the closed lower die shell and the upper die shell. The die is easy to install and disassemble. After the die groove is deformed, the drawing die can be disassembled and replaced.

[0013] This invention opens the valve and controls its opening angle, allowing the lubricating oil in the transparent oil storage tank to flow through the connecting pipe into the through hole, and then drip into the closed lower and upper mold shells, thereby dripping onto the steel wire passing between the lower and upper mold shells, lubricating the steel wire before it enters the mold groove.
