Description

Technical Field

[0001] The utility model relates to the technical field of wire manufacturing, in particular to a self-locking Haff nanometer wire-joining die which is convenient for disassembly and assembly. Background Art

[0002] In the traditional wire twisting process, the wire doubling die is the main tooling for forming multiple single wires. Generally, the material of the wire doubling die is hardwood and other materials, which are processed into wire doubling dies of different diameters. However, the wear resistance of this material is poor, so the wire doubling die needs to be constantly replaced during the production process to ensure that the outer diameter of the wire meets the process production requirements, especially when producing profiled wires. Since the profiled wires are tightly twisted, the wire doubling die wears faster during twisting production. The wire doubling die needs to be replaced many times to produce a wire, and the production efficiency is low. Therefore, alloy wire doubling dies are sometimes used in the production of profiled wires, and generally an integral alloy wire doubling die is used.

[0003] However, during the production process, the wire joining mold sometimes needs to be opened for processing and wire trimming. The commonly used Haff wire joining mold is simply divided into two pieces for processing. It cannot be completely closed during production, and an indentation will be formed on the surface of the conductor. Therefore, a self-locking Haff nano wire joining mold that is easy to disassemble and assemble is needed to meet the demand. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-7 A self-locking Haff nano-wire paralleling die that is easy to disassemble and assemble comprises a first Haff die 1 and a second Haff die 2. An inlet area 3, a sizing area 4 and an outlet area 5 are sequentially arranged from the same end of the first Haff die 1 to the other end. A T-shaped groove 6 is provided on the plane end of the first Haff die 1 from the outlet area 5 to the inlet area 3. The T-shaped groove 6 does not completely penetrate the first Haff die 1. A T-shaped block 7 is provided on the plane end of the second Haff die 2 from the outlet area 5 to the inlet area 3. A notch 8 is provided on the T-shaped block 7. A trapezoidal hole 9 is provided on one side pointing to the inlet area 3, a connecting column 10 is provided between the inner wall of one end of the trapezoidal hole 9 and the inner wall of one end of the slot 8, a double-sided trapezoidal slider 11 is slidably mounted on the connecting column 10, a trapezoidal surface at one end of the double-sided trapezoidal slider 11 is adapted to the trapezoidal hole 9, first springs 12 are provided on both sides of the T-slot 6, wedge-shaped top blocks 13 are provided on the ends of the two first springs 12 that are close to each other, and the two wedge-shaped top blocks 13 are both located between the trapezoidal hole 9 and the double-sided trapezoidal slider 11.

[0024] During installation, the plane of the first half mold 1 and the plane of the second half mold 2 are offset and fitted to each other, and after the T-slot 6 and the T-block 7 are aligned, the first half mold 1 is pushed to make the T-block 7 gradually slide into the T-slot 6. During the process, the side of the T-block 7 contacts the oblique side of the wedge-shaped top block 13, so that the wedge-shaped top block 13 pushes the first spring 12 to compress. When the wedge-shaped top block 13 coincides with the notch 8, the wedge-shaped top block 13 loses the thrust of the side of the T-block 7, and the first spring 12 rebounds, popping out the wedge-shaped top block 13, so that the plane of the wedge-shaped top block 13 contacts the connecting part of the notch 8 and the trapezoidal hole 9, thereby limiting the axial return movement of the first half mold 1. At this time, the installation connection between the first half mold 1 and the second half mold 2 is completed;

[0025] When the trimming operation is required, the first half mold 1 is moved again in the direction of installation, so that the wedge-shaped top block 13 contacts the double-sided trapezoidal slider 11, and the double-sided trapezoidal slider 11 is pushed to move toward one end of the notch 8. When the double-sided trapezoidal slider 11 contacts the notch 8, the movement of the double-sided trapezoidal slider 11 is restricted. At this time, the wedge-shaped top block 13 follows the movement of the first half mold 1, so that the wedge-shaped top block 13 pushes the first spring 12 to compress, and the wedge-shaped top block 13 moves from one end of the double-sided trapezoidal slider 11 to the other end. After that, the first spring 12 rebounds to push the wedge-shaped top block 13 out to the notch 8 Between one end and the double-sided trapezoidal slider 11, the first half mold 1 is pushed in the reverse direction at this time, so that the flat end of the wedge-shaped top block 13 pushes the double-sided trapezoidal slider 11 to move toward the trapezoidal hole 9, until the trapezoidal surface of one end of the double-sided trapezoidal slider 11 coincides with the trapezoidal hole 9, and the reversely pushed first half mold 1 drives the wedge-shaped top block 13 to combine with the trapezoidal surface leaked from the double-sided trapezoidal slider 11, so that the wedge-shaped top block 13 gradually drives the first spring 12 to compress, until the first half mold 1 drives the T-slot 6 to completely separate from the T-block 7, and the disassembly of the first half mold 1 and the second half mold 2 is completed.

[0026] Specifically, in the present embodiment, the first half mold 1 and the second half mold 2 are both made of carbide steel, and the surfaces are both nano-coated, so that the overall structure of the parallel mold is stable, the wear resistance is improved, and the loss is reduced.

[0027] Specifically, in the present embodiment, fixing grooves 14 are provided on the arc outer walls on both sides of the first half mold 1 and the second half mold 2. The fixing grooves 14 extend from the outlet area 5 toward the inlet area 3 and do not penetrate completely. The fixing grooves 14 facilitate the installation of the parallel mold on the machine body, thereby increasing the contact area between the bolt end and the parallel mold, thereby improving the stability of the parallel mold.

[0028] Specifically, in the present embodiment, the length of the T-slot 6 is greater than the length of the T-block 7, and sufficient space is provided for the secondary movement of the first half mold 1 when the parallel mold is disassembled.

[0029] Specifically, in the present embodiment, a second spring 15 is connected to one end of the T-block 7 pointing to the inlet area 3, and the second spring 15 contacts the inner wall of one end of the T-slot 6. The reaction force of the second spring 15 causes the first half mold 1 and the second half mold 2 to form an axial separation trend, thereby allowing the wedge-shaped top block 13 to be in close contact with the connection between the notch 8 and the trapezoidal hole 9, thereby improving the stability after installation.

[0030] Specifically, in this embodiment, guide grooves 16 are opened on the inner walls on both sides of the T-slot 6, the first spring 12 is connected to the inner wall of the guide groove 16 away from the opening, the wedge-shaped top block 13 is slidably adapted in the guide groove 16, and the guide groove 16 provides movement guidance and telescopic space for the wedge-shaped top block 13.

[0031] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
