Description

Technical Field

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

[0002] Wire stranding machine is a kind of mechanical equipment which can be widely used in various soft / hard conductor wires (copper wire, enameled wire, tinned wire, copper clad steel, copper clad aluminum, etc.) and electronic wires. Its main task is to twist multiple single conductors into one strand, and finally form a spiral shape to meet the process requirements of wire materials.

[0003] When the core copper wires are twisted by a twisting machine, the wire-releasing mechanism releases the copper wires. The copper wires are in a straightened state during twisting. The straightened copper wires are prone to breakage during twisting. After the copper wires break, the twisting machine continues to work, and the machine cannot know when the copper wires break, so it is impossible to stop twisting in time, resulting in poor quality of the twisted copper wire bundle. Utility Model Content

[0004] The utility model aims to propose a wire stranding machine to solve the shortcomings in the prior art that it is impossible to know when the copper wire is broken, so that the twisting cannot be stopped in time, resulting in poor quality of the twisted copper wire bundle.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Design of a stranding machine, including a mounting plate, wherein:

[0007] The mounting plate is fixedly connected to a motor, the output end of the motor is fixedly connected to a turntable, a plurality of wire-releasing mechanisms are connected to the turntable at equal intervals along the axis direction, a wire harness tube is fixedly connected to the turntable, a plurality of through holes are opened on the wire harness tube at equal intervals along the axis direction, and each of the wire-releasing mechanisms is connected to a wire breakage detection mechanism;

[0008] The wire breakage detection mechanism comprises a fixed frame, which is fixedly connected to the wire-releasing mechanism, a groove column is fixedly connected to the bottom end of the fixed frame, an extrusion piece is slidably connected to the groove column, and a pressure sensor is fixedly connected inside the groove column.

[0009] Preferably, an anti-corrosion layer is sprayed on the mounting plate.

[0010] Preferably, a plurality of stop plates with holes are connected to the wire harness tube at equal intervals along the axial direction, and the stop plates with holes are located between the wire release mechanism and the through hole.

[0011] Preferably, the extrusion member includes a connecting rod, which is slidably connected to the groove column, and the bottom end of the connecting rod is fixedly connected to a fixed seat, and a roller is rotatably connected to the fixed seat, and a limit frame is fixedly connected to the fixed seat, and the limit frame is located below the roller.

[0012] Preferably, the fixing seat and the limiting frame are an integral structure.

[0013] The wire stranding machine proposed by the utility model has the following beneficial effects:

[0014] During the rotation of the turntable, the straightened copper wire squeezes the extrusion, and the extrusion squeezes the pressure sensor. The pressure sensor measures the pressure value. When the copper wire breaks, the straightened copper wire is in a loose state, the copper wire separates from the extrusion, the extrusion loses thrust, the extrusion separates from the pressure sensor, and the pressure value detected by the pressure sensor returns to zero, so that the copper wire is known to be broken and the motor is stopped in time.

After the copper wire is straightened, it pushes the extrusion piece 73 upward, and the extrusion piece 73 squeezes the pressure sensor 74, and the pressure sensor 74 detects the pressure value. After the motor 2 is powered on and started, it drives the turntable 3 to rotate, and the turntable 3 drives the wire-releasing mechanism 4 to rotate. After the wire-releasing mechanism 4 rotates, the copper wires in the wire bundle tube 5 are twisted together.
