Central Plastic Tube Cable was born in this way
12# May 3 , Sunday, at 7 pm, Shenggao Cang, the cable company responsible for the distribution of goods, sent a red envelope in the employee WeChat group, and the group immediately became lively. The original cable company completed the equipment transformation and process design within 26 days at the request of the customer, and the central plastic tube type large logarithmic data cable produced was finally completed and delivered smoothly.
Nearly a month ago, I got the customer's sample. Its fine craftsmanship and design shocked the technicians of the cable company a little-the appearance of the sample line was extremely round, there was no wire strand on the surface of the sheath, and the wire pairs inside were all arranged around the central plastic pipe in standard concentric circles. The position of each pair of wires is fixed, one pair is opposite to the other, the inner layer and the outer layer are distinct, without any dislocation and strand jumping phenomenon; the shielded cable also considers the proximity effect of the line pair, the inner layer and the outer layer have different single-line structures, and the color spectrum also has special marks. This structure makes the performance of large logarithmic data cables very stable, and of course the production requirements are relatively high.
In the face of customer orders, the employees of the cable company are very worried. Because according to the current equipment situation, can not meet the production requirements, if you give up the order, the loss is not only sales, but also customers and the market. After careful consideration, Li Jinzhi, general manager of the cable company, made a decisive decision, took the order, and worked out a plan to transform the equipment before organizing production.
The delivery time required by the customer is only 26 days, which is very tight. Li Jinzhi invited equipment experts from Shanghai to study the equipment renovation plan together. The cable company also sent relevant technology, equipment and production personnel to the customer's factory twice to learn from the experience. Guo Zhijian, the monitor of the machine repair team, took part in the two studies. Although he was silent on weekdays, he had already made the idea of "stealing the teacher. Before the first departure, I had a comprehensive understanding of the idle equipment of the cable company. During the visit and study, I carefully considered the structure and performance of the other equipment, compared them, and determined the feasibility of equipment transformation. For the second time, further confirmation and communication were made, and the relevant data of the equipment were measured to ensure the accuracy after the transformation.
After a compact and sufficient demonstration, the renovation of the cable machine was carried out in full swing. For several machine mechanics in the workshop, the disassembly and assembly of idle machines were much more tiring than the installation and debugging of new machines. For a while, the machine broke down, for a while, the electrical cabinet tripped, for a while, and for a while there were parts that went wrong. The nerves of the masters were tested at any time.
The transformation of the pay-off frame and the determination of the mold size are the most critical links in this transformation. If there is no tension control of active pay-off, it is difficult to arrange the line pairs without jumping, and the mold size should be very accurate, so as to achieve the effect of positioning and shaping. If you want to buy an active pay-off rack, time and cost are both issues. Finally, the cable company uses the existing 26 head passive pay-off frame to control and adjust the tension to make it as uniform as possible, and uses the idle winding machine to ensure the roundness of the cable core.
When testing the machine, the problems were more obvious. The tension of the wire pair was uneven, the wire pair slipped out of the tension rod and was scratched. After the shutdown, the cable could not be effectively stopped, which led to the slack of the twisted wire... Problems followed one after another. In those days, the mechanic masters were all gray and oily all day, and they were busy back and forth. After many improvements and tests, a satisfactory sample was finally produced.
11 August 21 , the equipment renovation was finally completed, but it was less than half a month before the delivery date required by the customer. In order to ensure on-time delivery, the cable company held a special meeting to deploy the work tasks of various departments before delivery. The production department forced each process according to the construction period, and then deployed personnel according to the process arrangement. On the first day of formal production, the cable company also invited the customer's technical personnel to conduct on-site guidance.
In the following days, the cable company will mobilize the whole factory, with production personnel working 24 shifts, management personnel working at night, always paying attention to the production progress, and taking posts at any time in case of emergencies. In the past, most of the digital cabling posts were operated by one person, with 4 pairs of the following cables twisted. However, after the renovation, the central plastic pipe cabling post required two people to operate at the same time, with 25 pairs of the above cables twisted. The difficulty of the work increased and the manpower was obviously tense. According to the situation of each process, the workshop deployed personnel at any time to seize the progress. In order to ensure the stable operation of the machine, the eyes of the operators are always fixed on the machine and dare not relax for a moment. Such a high-intensity work, the day is good, the night shift is very difficult. To this end, the cable company prepared milk and snacks to increase nutrition for night shift personnel.
With the full cooperation of various departments, plates of colorful, round and bright central plastic tube type large logarithmic data cables successively walked off the production line. On the agreed delivery day of 12 April 3 , this batch of products were all produced and packaged according to the customer's requirements and ready for delivery. Cable company employees tense heart for nearly a month, finally relaxed.
The production of the central plastic tube large logarithmic data cable is an arduous test for the cable company. They have overcome all kinds of difficulties and realized their commitment to customers with their own efforts and wisdom and the spirit of perseverance and indomitable struggle. (lu chao-fang)

Daye Peak Declared 4 Invention Patents Last Year
In 2019, Daye Jianfeng Cement Company changed its thinking, actively explored and tested the use of new materials, and summarized the research results in a timely manner, and successively declared 4 invention patents. In the production process of low-alkali cement, Daye Peak changed the traditional scheme of using high-grade sandstone ingredients alone to replace part of the sandstone and part of the iron correction material with iron ore waste soil, which not only controlled the alkali content in the clinker, but also increased the Al2O3 content in the clinker, ensuring the easy burnability and high early strength of the clinker. Innovation has also been made in the raw material batching scheme, breaking the original high-grade and low-grade sandstones used together and changing them to separate batching of high-grade and low-grade sandstones respectively, thus avoiding the disadvantage of easy material segregation in the process of high-grade and low-grade sandstones used together. At the same time, the original four-component batching is changed to five-component batching, so that low-alkali clinker can be freely switched, which is convenient for production organization and production cost. On the basis of a series of innovative achievements, Daye Peak declared four invention patents in 2019: "a technology for producing clinker from gas sludge and dust collection in steel mills", "a method for treating sludge in machine-made sand mills", "an improvement in raw material batching method" and "a technology for producing low cement from iron ore mining waste soil", all of which have high practical value.
