"Mixed Reform" Enables Old state-owned Enterprises to Transform and Upgrade to Intelligence

Published:2021-06-04

Since the implementation of the mixed reform, NHI has made a new leap in development by integrating into the completely market-oriented system and mechanism of Fangda Group and relying on the Fonda’s abundant capital resource advantages and brand new business and development concepts. Through equipment upgrading and transformation, the company has further improved its product manufacturing capacity and significantly increased its market influence.

Intelligent Enterprises Add Greater Power

North Heavy Industry Automotive Steering System Branch focuses on mechanical steering column and intermediate shaft, and provides ancillary products for FAW Jiefang and Hongqi automobile manufacturers. Since the implementation of the mixed system reform in NHI, the company has introduced dozens of advanced processing, assembly and testing equipment, with a total investment of more than ten million yuan. Through the purchase of equipment, the machining of shaft parts realizes the automatic feeding and on-line dimension monitoring of manipulator, the stamping parts realize automatic feeding and continuous stamping, parts welding assembly has realized the automatic welding of all manipulator; the main assembly parameters of steering column and drive shaft can be monitored online and traceable. The product testing ability in the industry is in a leading position. After factory equipment upgrading, according to estimates, shaft parts processing efficiency increased by 80%, stamping parts processing efficiency increased by 200%, axial parts welding efficiency increased by 100%. On the one hand, labor costs are reduced, and on the other hand, product quality is improved. The labor cost can be saved nearly one million yuan every year, the qualified rate of products has been greatly improved, and more than 20 kinds of parts originally purchased have been made by NHI themselves.

After the transformation of the workshop shows that it is an intelligent and digital professional factory, welding manipulator, grinder manipulator, and lathe processing manipulator keep waving their arms, rhythmically processing parts of different specifications. "If there is a plane tree, there will be a phoenix." With the continuous investment in equipment renewal, the steering product market of NHI has undergone tremendous changes, and the number of auto factories coming to the factory for project review has gradually increased. In the past two years of mixed reform, the company has won the bidding for more than 20 new product projects from 12 auto factories in China.

At present, the steering products of NHI are not limited to the ancillary field of commercial vehicle steering column, and will continue to increase the development of the supporting market of passenger vehicle steering column, and constantly expand the market field.

Refinement Leads to High Quality Products

In order to meet the market demand, better complete the fine processing of gear products, and further improve the quality of products, NHI has introduced the leading equipment in the domestic gear processing industry, electronic generative gear measuring center and CNC gear forming grinding machine.

The electronic generative gear measuring center introduced by NHI has a maximum gear measuring diameter of 650mm, which fills the gap of backward gear machine testing accuracy. The equipment precision up to level 4, to achieve high precision detection, it uses electronic scanning probe for accurate detection, measurement center can be in fine grinding gear tooth profile of gear tooth before accurate measurement, provides simple, fast and effective measurement data support for the sequential grinding finishing sequence.

In addition, NHI also introduced the CNC gear shaping grinding machine, which is domestic well-known as gear machine tool manufacturer Qinchuan. Its equipment is the leading professional equipment for grinding hard surface gear, the maximum processing diameter is 800mm, the equipment has its own detection system, the introduction of the equipment makes up for the original development of grinding accuracy, efficiency, greatly improves the accuracy of gear processing and bulk gear processing efficiency.

Automation Has Led to Dramatic Increase in Productivity

The general assembly idler workshop of North Heavy Industry Bulk Material Equipment Branch has many years of experience in idler production, and has undertaken large projects in Turkey, Iran, Brazil, etc., which played an important role in the idler industry in domestics and overseas.

Since the implementation of mixed reform, in order to meet the future market demand, through the analysis of the production process of idlers and the comparison with other enterprises in the same industry, the company has timely upgraded the equipment and improved the level of equipment automation.

In the production process, the original shaft processing is long, which needs to use five equipment involving five operators and three processes to complete, the production technology is behind the same industry, the production efficiency is slow. The original pipe cutting equipment has been used for more than 30 years, with serious aging, frequent failures, low processing efficiency and poor precision. By purchasing two automatic double-head CNC lathes to replace the sequence processing of the original five lathes, which only equipped with one operator can complete the processing of most types of rollers. Through the purchase of an automatic loading and unloading pipe cutting machine, the use of automatic production equipment replaced the old manually operated machine tools to improve production safety at the same time and achieve the goal of improving processing efficiency, stable product quality.

Through the technical upgrading and transformation of the equipment, NHI has solved the quality problem of the bottleneck process, improved the production efficiency, ensured the delivery time of the products, improved the market reputation of the enterprise, and escorted the sustainable and healthy development of the enterprise.
