630/12+18 Rigid Stranders With Ground Shaft Driving.

JLK630/12+18 bobbin Rigid stranding machine with manual loading bobbin system.


This machine is mainly suitable for the production of large-length bare aluminum, bare copper wire and steel-cored aluminum stranded wire and aluminum alloy wire and fan-shaped conductor twisted and pressed, round conductor twisted and drawn tight. The equipment adopts 36-level traction gearbox, double active and double traction device, and the splitter wheel adopts natural branching to avoid the wire core wiping during the stranding process. The tension of the equipment release line is controlled by pneumatic tension to ensure the coil is full. The fully-disconnected automatic parking device with uniform tension when empty and with a unique function, the disconnected parking is directly controlled to each pay-disel, and the host automatically stops immediately when the disconnected disc is stopped.

4.1.5. Structural form: the main engine adopts 12 + 18 two-stage cage layout, and each section of cage is divided into four equal parts. The cage is carried by two large double row roller bearings, which are supported by gearbox and front support. The cage body is composed of cage, gearbox, front support, brake system, base, etc. The whole machine is driven by 75kW variable frequency motor.

4.1.6. Synchronous stranding: the 12 and 18 reel stranders have the function of synchronous stranding up to 30 cores. The same speed box is used for the two sections of stranding cage, and 12 synchronous pipes are preset inside the 18 reel stranding cage to complete the stranding of up to 30 wires in the outer layer.

4.1.7. Hanging way: the process of tightening and loosening the coil is completed by the worm gear clamping structure driven by the electric wrench, and the turbine box has the function of automatic locking, which is convenient, fast and safe to operate; The turbine is supported by bearing, which is accurate in positioning, not easy to wear and avoid jamming. The coil is installed into the winch cage through the lifting device in the workshop.

4.1.8 Structural features of gearbox and front support: the internal gear of gearbox is made of 20CrMnTi material, carburized, and the grinding accuracy is grade 6. The 6-stage speed change of the box has positive, negative and neutral gears, and the inside of the box is sprayed and lubricated by an independent oil pump motor. The front support is made of gray cast iron with lost foam casting process, which is cast and processed as a whole, with beautiful appearance and high strength.

4.1.9. Structural characteristics of the hinge: the frame adopts the plate CNC laser cutting and blanking, and the large bending machine bending processing. This process can minimize the welding seam and improve the overall structural strength. After the overall assembly and welding forming, the high temperature annealing treatment can eliminate the internal stress, and then the large machine tool is processed as a whole to ensure the concentricity, stable operation, high mechanical strength and no deformation for a long time.

4.1.10. Bottom structure: the base is made of high-quality plate and rectangular square tube, with beautiful appearance and high structural strength.

4.1.11. Braking system: each section of the main engine is equipped with multiple groups of flat air brakes. When parking, the driving motor stops working, and all brakes act at the same time. The whole braking process is efficient and stable.

4.1.12. Line breaking and parking: equipped with advanced dxj full-automatic vector pulse line breaking and parking protection system, the line breaking monitoring can be accurate to each coil, and the system can stop and brake in time when the wires in the coil are used or broken. The monitoring system is controlled by wireless communication to reduce wire laying, improve monitoring accuracy, reduce operator allocation and improve production efficiency.

4.1.13. Pay off tension: mechanical friction is used to provide tension, and the tension is adjusted manually. The tension output is even.

4.1.14. Pre deformer: a single wire pre deforming device is installed at the front end of each section of main machine to prefabricate the stranding pitch and improve the quality of finished wire.

4.1.15. The front end of each section of the winch cage is equipped with: emergency stop, inching button, and a 220 V power supply fast plug row, which is convenient for operation and use.

4.1.16. Wear resistant alloy nozzles or wire rollers are set at all wire holes and easy to scratch wire positions.

4.1.17 Safety cover: one side wall safety net made of perforated plate.

4.118. Others: a group of 30 reels is added to the 18 reel winch cage, which can be interchanged with the original 18 reel reels for synchronous stranding
