1.大长度连续叠加组合生产方式
 
Continuous superposition combined production mode of 1. large lengths
 
 
 
大长度连续叠加组合生产方式,对电线电缆生产的影响是全局性和控制性的,这涉及和影响到:
 
The influence of the large-length continuous stacking combined production mode on the wire and cable production is global and controllable, which involves and affects:
 
 
 
(1)生产工艺流程和设备布置
 
(1) production process and equipment layout
 
 
生产车间的各种设备必须按产品要求的工艺流程合理排放,使各阶段的半成品,顺次流转。设备配置要考虑生产效率不同而进行生产能力的平衡,有的设备可能必须配置两台或多台,才能使生产线的生产能力得以平衡。从而设备的合理选配组合和生产场地的布置,必须根据产品和生产量来平衡综合考虑。
 
All kinds of equipment in the workshop must be reasonably discharged according to the technological process required by the product, so that the semi-finished products in each stage can be transferred in sequence. In order to balance the production capacity of the production line, the equipment configuration should consider the balance of production capacity with different production efficiency, and some equipment may have to be equipped with two or more stations. Therefore, the rational selection and combination of equipment and the layout of production sites must be balanced and considered comprehensively according to the product and production volume.
 
 
 
(2)生产组织管理
 
(2) production organization and management
 
 
 
生产组织管理必须科学合理、周密准确、严格细致,操作者必须一丝不苟地按工艺要求执行,任何一个环节出现问题,都会影响工艺流程的通畅,影响产品的质量和交货。特别是多芯电缆,某一个线对或基本单元长度短了,或者质量出现问题,则整根电缆就会长度不够,造成报废。反之,如果某个单元长度过长,则必须锯去造成浪费。
 
The production organization and management must be scientific, reasonable, accurate and meticulous. The operator must follow the requirements of the process meticulously. Any problem in one link will affect the patency of the process flow, and affect the quality and delivery of the product. Especially multi-core cable, a pair of lines or basic unit length is short, or quality problems, the whole cable will be insufficient length, resulting in scrap. Conversely, if the length of a unit is too long, it must be sawn for waste.
 
 
 
(3)质量管理
 
(3) quality management
 
 
 
大长度连续叠加组合的生产方式,使生产过程中任何一个环节、瞬时发生一点问题,就会影响整根电缆质量。质量缺陷越是发生在内层,而且没有及时发现终止生产,那么造成的损失就越大。因为电线电缆的生产不同于组装式的产品,可以拆开重装及更换另件;电线电缆的任一部件或工艺过程的质量问题,对这根电缆几乎是无法挽回和弥补的。事后的处理都是十分消极的,不是锯短就是降级处理,要么报废整条电缆。它无法拆开重装。
 
The production mode of large-length continuous superposition combination will make any link and instantaneous problems occur in the production process, which will affect the quality of the whole cable. The more the quality defects occur in the inner layer, and the failure to detect the termination of production in time, the greater the losses will be. Because the production of wire and cable is different from the assembled product, it can be disassembled and replaced, and the quality of any part or process of wire and cable is almost irreparable and irreparable to the cable. Handling afterwards is very negative, not sawing short or downgrading, or scrapping entire cables. It can't be reassembled.
 
 
 
电线电缆的质量管理,必须贯串整个生产过程。质量管理检查部门要对整个生产过程巡回检查、操作人自检、上下工序互检,这是保证产品质量,提高企业经济效益的重要保证和手段。
 
The quality management of wire and cable must be carried out throughout the whole production process. The inspection department of the quality management and inspection should inspect the whole process of production, self-examination and mutual inspection, which is an important guarantee and means to guarantee the quality of the product and improve the economic benefit of the enterprise.
 
 
 
2.生产工艺门类多、物料流量大
 
2. the production process is large and the material flow is large
 
 
 
电线电缆制造涉及的工艺门类广泛,从有色金属的熔炼和压力加工,到塑料、橡胶、油漆等化工技术;纤维材料的绕包、编织等的纺织技术,到金属材料的绕包及金属带材的纵包、焊接的金属成形加工工艺等等。
 
The process of wire and cable manufacturing involves a wide range of technologies, ranging from non-ferrous metal smelting and pressure processing to plastic, rubber, paint and other chemical technologies; textile technology for wrapping and weaving of fiber materials, wrapping of metal materials and metal strip, welding metal forming processes, and so on.
 
 
 
电线电缆制造所用的各种材料,不但类别、品种、规格多,而且数量大。因此,各种材料的用量、备用量、批料周期与批量必须核定。同时,对废品的分解处理、回收,重复利用及废料处理,作为管理的一个重要内容,做好材料定额管理、重视节约工作。
 
All kinds of materials used in wire and cable manufacturing are not only in categories, varieties, specifications, but also in large quantities. Therefore, the dosage, dosage, batch period and volume of various materials must be approved. At the same time, the decomposition and treatment of waste products, recycling, reuse and waste disposal, as an important content of management, do a good job in the management of materials and pay attention to the work of saving.
 
 
 
电线电缆生产中,从原材料及各种辅助材料的进出、存储,各工序半成品的流转到产品的存放、出厂,物料流量大,必须合理布局、动态管理。
 
In the production of wire and cable, from the import and storage of raw materials and various auxiliary materials, the circulation of the semi-finished products of each process to the storage and production of the products, the large flow of materials, the rational distribution and dynamic management must be made.
 
 
 
3.专用设备多
 
3. special equipment many
 
 
 
电线电缆制造使用具有本行业工艺特点的专用生产设备,以适应线缆产品的结构、性能要求,满足大长度连续并尽可能高速生产的要求,从而形成了线缆制造的专用设备系列。如挤塑机系列、拉线机系列、绞线机系列、绕包机系列等。
 
Wire and cable manufacturing and using special production equipment with the technical characteristics of the industry, in order to meet the structure and performance requirements of cable products, meet the requirements of large length continuous and as high speed production as possible, thus forming a series of special equipment for cable manufacturing. For example, extrusion machine series, wire drawing machine series, stranding machine series, wrapping machine series, etc.
 
 
 
电线电缆的制造工艺和专用设备的发展密切相关,互相促进。新工艺要求,促进新专用设备的产生和发展;反过来,新专用设备的开发,又提高促进了新工艺的推广和应用。如拉丝、退火、挤出串联线;物理发泡生产线等专用设备,促进了电线电缆制造工艺的发展和提高,提高了电缆的产品质量和生产效率。
 
The manufacturing process of wire and cable is closely related to the development of special equipment and promotes each other. New process requirements, promote the emergence and development of new dedicated equipment; in turn, the development of new dedicated equipment, and improve the promotion and application of new technology. Such as wire drawing, annealing, extrusion series line, physical foaming production line and other special equipment, promote the development and improvement of wire and cable manufacturing technology, improve the quality of cable products and production efficiency.
