Description

Technical Field

[0001] This utility model relates to the field of mold equipment technology, and in particular to a small-diameter wire drawing mold. Background Technology

[0002] Wire drawing dies generally refer to various dies used for drawing metal wires, as well as dies for drawing optical fibers. All wire drawing dies have a hole of a specific shape in the center—round, square, octagonal, or other special shapes. As the metal is drawn through the die hole, its size decreases, and even its shape changes. For drawing soft metals (such as gold and silver), a steel die is sufficient; a steel die can have multiple holes of different diameters.

[0003] Most existing wire drawing dies only come in one specification, and changing to other specifications is quite complicated. Utility Model Content

[0004] To address the aforementioned technical problems, a small-diameter wire drawing die is provided.

[0005] To achieve the above objectives, in a preferred embodiment of the present invention, the mold body is provided with a wire drawing opening at the top and a rotatable flap on the side. A fixing mechanism is provided on the flap to fix a rotating disk II inside the mold body. The rotating disk II has wire drawing holes.

[0006] In a preferred embodiment, the present invention may be further configured such that the fixing mechanism includes a rotating block, the rotating block is connected to the flip plate through a spline, the end of the spline is provided with a rotating handle, and follower arms are fixed at the upper and lower ends of the rotating block respectively, and the ends of the follower arms are connected to tension arms through pins respectively, and the ends of the tension arms are fixed with pressure blocks, which clamp the end of the rotating disk II.

[0007] In a preferred embodiment, the present invention may be further configured such that the rotating block is disposed on a rotating disk, the rotating disk is disposed on the flip plate through a groove, and a gripping handle is provided on both sides of the surface of the rotating disk.

[0008] In a preferred embodiment, the present invention may be further configured such that one end of the flip plate is hinged to the mold body via a pin.

[0009] In a preferred embodiment, the present invention can be further configured such that the second rotating disk is connected to the mold body through a groove, and the second rotating disk with different specifications of wire drawing holes can be replaced as required.

[0010] In a preferred embodiment, the present invention may be further configured such that the external thread of the wire drawing opening is provided, and the external thread is connected to the top threaded hole through the engagement of the external thread.

[0011] In a preferred embodiment, the present invention may be further configured such that fastening locks are provided on the flap, the rotating block, and the rotating disk.

[0012] Beneficial effects: This utility model provides a small-diameter wire drawing die with a compact structure. The size of the wire drawing holes and the wire drawing openings inside and on the top can be quickly changed, making it highly applicable and easy to replace. Attached Figure Description
