Description

Technical Field

[0001] The utility model relates to the technical field of wire twisting machines, in particular to a 7-core high-speed wire twisting machine. Background Art

[0002] Wire twisting machines are used to twist various soft and hard conductor wires such as copper wire, enameled wire or copper clad aluminum, so that each twisted single wire is twisted together into a whole. Wire twisting is generally divided into two types: concentric layer twisting and bundle twisting. Concentric layer twisting means that each twisted single wire is twisted around the twisted wire in layers and in an orderly manner with the center line of the twisted wire as the axis; bundle twisting means that multiple twisted single wires are twisted together in the same direction and pitch without layers. In the twisting process, each twisted single wire needs to be unwound and spread from its own coil before twisting.

[0003] The traditional structure of the existing 7-core stranded wire is in the form of a steel pipe, so it is called a tube stranding machine. Due to structural limitations, the straight-line distance of the equipment is long, and a supporting wheel must be installed below. When running at high speed, the vibration is large, the noise is high, and the tube body only produces one wire stranding pitch per rotation, which has low production efficiency. Since the tube stranding body itself is heavy, the matching motor power is also large, generally 37KW, a large amount of energy is lost, which is contrary to energy conservation and emission reduction. For this reason, our company's technical personnel combined with many years of professional equipment manufacturing experience, boldly innovated, and developed a more efficient, energy-saving and environmentally friendly stranded wire product. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a 7-core high-speed wire twisting machine.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a 7-core high-speed wire twisting machine, including a support frame, a first bearing seat and a second bearing seat are fixedly connected on both sides of the support frame, the first bearing seat and the second bearing seat are rotatably connected inside the first rotating shaft, the first twisted body and the second twisted body are fixedly connected at opposite ends of the first rotating shaft, a basket frame is arranged above the support frame and between the first twisted body, a plurality of wire drums are rotatably connected in the basket frame, a fourteen-wheel straightening device is arranged on one side of the support frame, and a double-wheel traction machine, a reciprocating wire arranging machine and an axis-type wire arranging machine are arranged on one side of the fourteen-wheel straightening device.

[0006] Furthermore, a support rail is fixedly connected to the support frame, and a crane is arranged on the support rail.

[0007] Furthermore, a first sprocket is fixedly connected to the outer end of the first rotating shaft, and a dual-axis motor is fixedly connected to the upper end of the supporting frame.

[0008] Furthermore, both ends of the output end of the dual-axis motor are fixedly connected to a second rotating shaft, and the outer ends of the second rotating shaft are fixedly connected to a second sprocket.

[0009] Furthermore, a chain is arranged between the second sprocket and the first sprocket.

[0010] Furthermore, the number of the wire reels is seven.

[0011] Beneficial effects of the utility model:

[0012] When the utility model is in use, the 7-core high-speed wire twisting machine breaks the traditional 7-core stranded wire twisting principle, and installs seven wire drums in the same basket frame. The wires of each wire drum enter the first twisting body through their own wire wheel group. In this process, the seven wires are twisted for the first time, and the initially twisted strands are guided by the wire wheels to enter the second twisting body at the other end, where they are twisted for the second time. The rotation speed of the twisting body is equivalent to that of the tube twisting machine. The difference is that the twisting method of the device is to twist twice front and back. Therefore, its production efficiency is twice that of the tube twisting machine. The twisted wires enter the fourteen-wheel straightening device, where the internal stress generated when the wires are twisted can be effectively removed. The straightened wires are pulled by a double traction wheel with a diameter of 600mm, and the wires are led to the shaft-type wire-taking and arranging machine. The power of the double-axis motor of the twisting body is only 11KW, and the production cost is much lower than that of the tube twisting machine. BRIEF DESCRIPTION OF THE DRAWINGS
