1.拉制在金属压力加工中.在外力作用下使金属强行通过模具(压轮),金属横截面积被压缩,并获得所要求的横截面积形状和尺寸的技术加工方法称为金属拉制。
电线电缆生产工艺有哪些？
电线电缆的主要工艺电线电缆是通过：拉制、绞制、包覆三种工艺来制作完成的，型号规格越复杂，重复性越高。
1.拉制
在金属压力加工中.在外力作用下使金属强行通过模具(压轮),金属横截面积被压缩,并获得所要求的横截面积形状和尺寸的技术加工方法称为金属拉制。
拉制工艺分：单丝拉制和绞制拉制。
2.绞制
为了提高电线电缆的柔软度、整体度，让2根以上的单线，按着规定的方向交织在一起称为绞制。
绞制工艺分：导体绞制、成缆、编织、钢丝装铠和缠绕。
3.包覆
根据对电线电缆不同的性能要求，采用专用的设备在导体的外面包覆不同的材料。包覆工艺分：
A.挤包：橡胶、塑料、铅、铝等材料。
B.纵包：橡皮、皱纹铝带材料。
C.绕包：带状的纸带、云母带、无碱玻璃纤维带、无纺布、塑料带等，线状的棉纱、丝等纤维材料。
D.浸涂：绝缘漆、沥青等

( copper ) wire, cable production process mainly includes the following several steps:1 wire filament (that is, a very fine copper wire is wound into a copper wire ):
The 2 insulating wire core extrusion ( through the extruder with PVC plastic copper wire wrapped into the insulated conductors ): extrusion?
3 spark experiment ( used to test 2 step out of the line to see if there is any breakage. ):
4 wire, a disc (that is, 2 steps of extrusion of the insulated wire wound on the plate storage ):
The 5 extruded sheath ( is through the extruder with PVC plastic 2 / 3 insulated wire wrapped into cable ): extrusion
The above is a wire production process, well after the need to wire, connected with the plug into the plug line, concrete steps are as follows:
1 wire (that is, a stripped of a PVC sheath ):
2 ( bracket ) riveting (that is, head and sheet metal of the plug by machine pressure, connected together ):
3 Baptist tin ( some thread needs in tin water dip, in order to ensure thread copper not scattered ):
4 plug injection: plug injection?
The 5 power-on test ( test plugs and wires are conducting good ):
The 6 amendment ( wrapped with scissors to cut together with thread, ribbon tied ):
7: Packing Packaging
A 6 cutting ( 5 steps in the cable according to the length requirements into a section of the section ):
