Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire strands, in particular to a double-ended stranded wire twisting mechanism. Background Art

[0002] With the development of the electronics industry, enameled wire is increasingly used in the manufacture of electrical components such as motors and transformers. In these applications, the enameled wire usually needs to be twisted to improve its mechanical strength and electrical performance. Traditional twisting processes mostly use manual operations or semi-automatic equipment. These methods have problems such as low production efficiency and unstable product quality.

[0003] While existing enameled wire twisting equipment on the market can achieve a certain degree of automation, it often only operates on a single wire and cannot meet the demand for twisting multiple wires simultaneously, especially when rapid and continuous production is required. Furthermore, due to the lack of an efficient dual-station design, traditional equipment cannot twist two enameled wires simultaneously, resulting in low production efficiency.

[0004] Therefore, it is necessary to develop a novel double-ended wire twisting mechanism to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the utility model provides a double-ended stranded wire twisting mechanism, which aims to solve the problems in the prior art of low twisting efficiency of enameled wires and inability to twist two enameled wires at the same time.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a double-headed stranded wire twisting mechanism, including a double-station twisting assembly and auxiliary components respectively arranged on both sides of the double-station twisting assembly, the double-station twisting assembly including: a bottom plate, provided with a belt avoidance opening; two vertical plates, symmetrically arranged on both sides of the belt avoidance opening and having the same structure; two clamping structures, respectively fitted on both sides of the two vertical plates; four wire clamping structures, respectively fitted on the outside of each end of the two clamping structures; the rotating shafts on the two clamping structures located between the two vertical plates are synchronously engaged and driven by the belt of the driving motor arranged at the lower end of the bottom plate, the wire clamping structure is used to clamp the static wire end of the enameled wire, the clamping structure is used to clamp and twist the dynamic wire end of the enameled wire, and the auxiliary component is used to drive the clamping structure to release the enameled wire.

[0007] Based on the above, the beneficial effect of a double-headed twisting mechanism is to solve the problems of low twisting efficiency of enameled wire and inability to twist two enameled wires at the same time in the existing technology; it is mainly reflected in: the double-station twisting assembly of the utility model is provided with two clamping structures and wire clamp structures on the outside of each end of the two clamping structures. The two enameled wires first pass through a wire clamp structure at the same time, and then pass through the moving wheel chuck component at one end of the clamping structure corresponding to the wire clamp structure, pass through the rotating shaft, and come out from the moving wheel chuck component at the other end of the clamping structure, and then pass through another wire clamp structure to be connected to the next operating device. When twisting, the two wire clamp structures corresponding to the two enameled wires first clamp the enameled wire positions of preset lengths, and the driving motor drives the two moving wheel chuck components to rotate simultaneously, which can jointly complete the twisting operations of the two enameled wires at two positions, greatly increasing the twisting efficiency of the enameled wires.

[0008] Furthermore, each of the clamping and rotating structures is also provided with two dynamic wheel chuck components, which are symmetrically arranged at both ends of the rotating shaft respectively, and the dynamic wheel chuck components include an inner frame, an outer frame sleeved outside the inner frame, a static pressure wheel positioned on the inner frame, a dynamic pressure wheel slidingly fitted with the inner frame, and a driving spring connected between the inner frame and the outer frame, the inner frame is slidingly fitted on the outer frame through the static pressure wheel, and both sides of the dynamic pressure wheel pass through the inner frame and are positioned on the outer frame.

[0014] Furthermore, the wire clamp structure includes a wire clamping frame, a small cylinder arranged at the upper end of the wire clamping frame, and a wire pressing platform arranged inside the wire clamping frame. The output end of the small cylinder cooperates with the wire pressing platform to clamp the static wire end of the enameled wire.

[0015] Based on the above, the beneficial effect of the wire clamp is to install a small cylinder and a wire crimping platform; the beneficial effect of the small cylinder is to ensure the precise clamping and release of the static end of the enameled wire; the beneficial effect of the wire crimping platform is to ensure the firm clamping of the static end of the enameled wire to prevent movement during the twisting process.

[0016] Furthermore, the auxiliary component includes two wire-releasing cylinders, both of which are arranged on the positioning guide rail and correspond to one side of the two moving wheel chuck components respectively. The output end of the wire-releasing cylinder completes the operation of releasing the enameled wire by pushing the outer frame.

[0017] Based on the above, the beneficial effect of the wire-releasing cylinder is to control the movement of the outer frame, thereby achieving the release of the enameled wire by the moving wheel chuck component and ensuring the continuity of the twisting process of the enameled wire.
