Device composition and classification of cable machine
- 2019-04-10-

The cable-forming machine is the equipment used to cable, that is, the insulated cores are twisted together and The equipment for filling and wrapping is suitable for the cable-forming and mounting of multi-core rubber cables, plastic cables, cross-linked cables, telephone cables and control cables of various cross sections. Today, Xiaobian will give you a detailed understanding of the equipment composition, classification, installation, operation points and maintenance of the cable machine, which is convenient for your use.

Composition of cable machine equipment

The cable machine equipment is provided by a pay-off frame, Winch cage, wire mold base, wrapping machine, loading machine, metering device, traction device, wire and cable rack, transmission system and electrical system.

1, transmission

The main power is driven by a speed control motor. After 1:1.367 times double shaft gear reducer deceleration, the first pass to the corner box and the main gear box to drive the main machine to rotate, the other end through the universal joint to the wrapper head, steel head, 27-stage traction gearbox. The speed of the transmission shaft is 394.7r/min, and the receiving and discharging line frame is driven separately.

2, stranded cage

from hollow spindle, support disc, reel The frame is composed of a structure similar to that of a stranding machine, and a wire frame with an insulating core disk is arranged on the hinged cage. There are different types of cable machines in various types of cable machines. Large cable machines are generally three or six wire racks, and small cable machines can have 18 or 24 or more wire racks.

There is a brake on each of the reel cages to control the tension of the core during twisting. The speed of the winch is adjusted by the shifting gear and the direction of rotation can also be changed. There are fixed struts at the front of the cage to hold the filling reel.

3, wire mold base

Two mold bases are mounted on the frame Two parts of the bottom cover can be opened and closed. The mold base is equipped with a split mold, and the upper cover is pressed by a screw to fix the split mold. The frame is equipped with a hand wheel and a screw rod, which can adjust the front and rear of the mold base to adapt the die mouth to the twist angle, so that the cable can be well twisted in the wire mold.

The splicing die can be replaced as needed. Its function is to make several insulated cores merge and twist into the correct round cable.

4, winding head

6-speed gearbox, Φ400×3 The wrapping device and the movable mold frame are composed. The wrapping head is used to wrap the plastic tape after the cable is wound, and the wrapping tape can also be used. The belt tension control is manually adjusted, and the winding head is input from the main drive shaft to the six-stage gearbox. The required strap pitch and forward and reverse straps can be achieved by changing the handle. In order to prevent the cable from vibrating during the tape winding process, the movable frame die can be used to achieve the position of the mold frame.

5, steel toe cap

Six-speed gearbox, rotating bracket, The tailstock is composed and mounted on the chassis. Two pairs of Φ600 steel reel discs are installed on the rotating bracket for the steel strip to be discharged. The bottom surface of the fixed plate is provided with a mechanical tension adjusting device, and the steel head is semi-tangential, and can be wrapped with a thin steel strip or a copper strip.

The steel toe cap is input from the main drive shaft and passed to the six-stage gearbox. The required belt pitch and forward and reverse straps can be passed. The change handle is reached.

6, traction device

Use it to twist the cable The cable is drawn and wound onto the take-up reel. The traction sheave is equipped with a rolling bearing supported by a steel shaft fixed to the underframe. The power is input from the main drive shaft, passed to the 27-speed gearbox, and then passed through a set of reduction gears to reach the traction wheel drive. A variety of speeds are available with variable speed handles to meet a variety of stranding pitch requirements.

7, the cable rack

is used to twist the cable Winding on the take-up reel, the storage speed should match the traction speed. The take-up power is shifted by the torque motor through the transmission gearbox, passed through the universal joint, and then decelerated by a pair of bevel gears, and then transmitted to the take-up spool. The wire tray is lifted and lowered by another motor through the worm wheel, the screw rod and the nut. The cable adopts the polished rod type cable, which has flexible movement, quick adjustment and convenient use.

Classification of cable machines

Cable machines have common and coiled Two types of conventional cable-forming machines include cage-type cable-forming machines and disk-type cable-forming machines. Regardless of the disc or cage cable machine, there is a star frame for placing the filler for the cable. After the stranding frame, they are respectively a parallel mold base bracket, a wrapping head, a pulling device, a wire take-up device and the like.

1. Cage cable-forming machine

Detailed equipment composition of the cable machine , classification, installation, operation and maintenance points

The medium and small cable-forming mechanism causes the cage, and the twisted part is like the cage of the cage machine. Types +6/400 and 1+6/1000. In addition, depending on the rotational speed, the cable-forming machine can generally be divided into two types: a cage cable-forming machine and a high-speed cage cable-forming machine. Among them, the high-speed cage cable-forming machine is used for twisting of copper-core aluminum stranded wire and bare aluminum wire, and can also be used for cable-forming of plastic cable and rubber cable.

2, disc type cable machine

large cable machine made into disc The cable-forming speed is generally below 10m/min, such as 1+3/1600, 2+3/1600 and 1+3/2400. The larger pay-off discs are 1600mm and 2400mm respectively.

The large winch of the disc-type cable-laying machine is fastened to a hollow shaft by discs of different sizes, and there are three discs with discs between the two discs. The frame of the reel tray is equipped with a gear mechanism for back-twisting. The stranded part of the disc type cable machine has a main bearing, the rear end of the hollow shaft is rotated therein, and the front and rear discs are supported by the supporting wheel, and the front end of the hollow shaft is a branching board, so that the insulated wire core before twisting is Enter the parallel mode in the correct way and prevent the insulated core from twisting back.

3, coiled cable-forming machine

The cable-forming machine is a relatively new cable-forming equipment. It has high production efficiency and speed of 30m/min or more. It can be used in a wide range of power cables, and can also be used for communication cables and control cables. Stranding of split conductors of large-section ultra-high voltage cables, such as 1+3/300 three-meter cable-forming machines.
