Mechanical Industry Standard of the People's Republic of China Wire and Cable Twisting Equipment Type and Dimensions Part 1 General Provisions 1 Subject Content and Scope of Application This standard specifies the type and dimensions of wire and cable twisting equipment. JB/T5817.1—91 The type and dimensions specified in this standard are applicable to the design, manufacture, acceptance, identification and quality assessment of various types of twisting equipment for wires and cables. 2 Reference standards GB2900 GB4004 GB4005 JB4015 JB4032 JB4033 Electrical terminology Priority numbers and priority number systems Wire and cable machine reels Wire and cable delivery reels Common parts for cable equipmentWww.bzxZ.net Wire-reeling and -releasing devices Common parts for cable equipment Traction devices Common parts for cable equipment Wrapping devices JB/DQ8193PND series machine reels 3 Terms 3.1 The definitions of terms in this standard adopt the interpretations of GB2900. 3.2 Rotating body for stranding Rotating body for stranding The rotating part in the stranding equipment that makes the individual strands move around the central axis of the equipment to complete the stranding of the workpiece is referred to as the rotating body. The guide rod mechanism or the slewing bow is the stranding rotating body of the bundle stranding equipment. The simplified body and the slewing bow are the stranding rotating bodies of the tube stranding equipment. The cage is the stranding rotating body of the cage stranding equipment. The (rewinding) frame is the stranding rotating body of the coil stranding equipment. 3.3 Stranding cage section The stranding cage that completes the stranding of one layer of components in the cage stranding equipment is called a stranding cage section. It consists of an independent transmission gearbox, a braking device, a die pressing device and a stranding cage rotating body. It is named after the number of pay-off drums in the stranding cage, such as a 6-reel stranding cage section and a 12-reel stranding cage section. 3.4 Bobbin frame A device or component for placing the pay-off drum or the take-up drum in the stranding rotating body. It consists of a drum support device and a tension device. 3.5 Revolution circle Revolution circle The index circle formed by the supporting centers of the reels on the rotating body when the cage of the Y-type stranding equipment is in operation. 3.6 Rotation circle Rotation circle The largest radial trajectory circle formed by the self-rotation of the reel rack and the reels on it due to back-twisting when the cage revolves. 4 Naming and code 4.1 Code Approved by the Ministry of Machinery and Electronics Industry on October 17, 1991, 54 Implemented on October 1, 1992 Category code Conductor stranding (stranding machine) equipment category Cable core stranding (cable making machine) equipment category Cable core component stranding equipment category 4.1.2 Series codes are shown in Table 1. Series name Bundle twisted series Tube twisted series Cage twisted series Type code as shown in Table 2 Derived code Stranding machine series 4.2 Representation method A, B, C Horizontal disc type Straight disc type Cradle type (Plane type) JB/T5817.1—91 Series name Bundle twisted series Tube twisted series Cage twisted series Disk twisted series Cableing machine series 4.2.1 The equipment is represented by the product marking composed of its name code and specification code. Its composition is as follows: Name code 4.2.2 Example Specification code Standard number Specification code Horizontal line disc type Linear disc type Cradle type (Plane type) Non-traction type Wheel traction type Crawler traction type Derived code (if any) Type code Series code Cage stranding machine, cradle type, wire reel specification 500mm, wire reel configuration is 6 plus 12, a total of 18 reels. Expressed as: No. JLY500/6+12JB/T5817.4-91 "Type and size of wire and cable twisting equipment Part 4 Cage twisting equipment" 55 JB/T5817.191 (Conductor) wire bundling machine, H type, specification 500, expressed as: JSH500 5 General provisions JB/T5817.2-91 "Type and size of wire and cable twisting equipment Part 2 Bundle twisting equipment". The size should be determined on a scientific basis and in accordance with GB321 regulations, and the value should be taken according to the priority number or priority number system as much as possible. 5.1 Key elements in product use should clearly specify dimensions: 5.2 Interface dimensions inside and outside the product; interchangeability dimensions; Dimensions indicating series specifications; Dimensions of installation anchor screw holes and related process dimensions. d. 5.3 Dimensions of the reel rack for pay-off or take-up reels in twisted rotating bodies. For reels with specifications of 630 or below, the dimensions should be processed according to the PND type reel type. If necessary, the top cone replacement method can be used for PN type reels.
