With the rapid development of construction machinery and automobile fields, its production mode is gradually moving towards automation and high speed. The industry has more and more stringent requirements for the stability of equipment operation, high speed of transmission speed, and flexibility of structural design. . In this context, manufacturers are constantly seeking changes, including a Fortune 500 company in the field of construction machinery. At the end of last year, the company launched a new Industrial park for large-scale production of heavy-duty trucks, diesel engines, other core industrial chains and new-generation construction machinery, in order to create a world-class model of “smart manufacturing”. Among them, NORD provided safe, reliable, energy-saving and efficient drive technology solutions for the project.

Difficulties of the project: complex process and high quality requirements in the painting workshop

As a benchmark project of intelligent manufacturing, the industrial park faces many difficulties in the construction process. Normally, vehicle manufacturing is divided into four major processes: stamping, welding, painting and final assembly. Among them, painting belongs to decorative and protective multilayer coating, which is a process with many processes and high quality requirements in automobile manufacturing. In addition, the painting workshop also needs to control process parameters such as temperature, humidity, pressure, and flow rate during the production process. These processes are all flow operations, and the upper and lower processes need to rely on the conveying system to achieve. Therefore, in a modern automobile painting line, the automation level and performance of the conveying system determine its production capacity, and the application of the drive system plays a key role in the stability of the process operation and the increase in production capacity.

Solution: Tailor-made drive system to ensure high-speed, stable, safe and reliable coating process

At present, the mechanized conveying system of the painting workshop of the project is composed of aerial and ground conveying equipment. The main task is to ensure that various types of white bodies and some spare parts complete pre-treatment, electrophoresis, body drying, sealant, spraying, etc. in the painting workshop. process, and send the qualified car body to the conveyor line of the final assembly workshop. Its conveying equipment mainly includes aerial and ground conveyors, ground chains, rolling beds, elevators, positioning mechanisms, etc. Among them, the rolling bed is widely used because of its convenient maintenance and easy speed control. In order to ensure high-speed and stable operation of roller beds and other conveying equipment, accurate positioning, safety and reliability, and easy maintenance, NORD used the professional checking software NORDcalc to check the fatigue strength and yield of the internal bearings and gears of the gearbox after the initial selection of the project. Intensity, so as to select the product model with the ideal speed ratio. In the end, NORD provided nearly 500 drive devices for the high temperature power roller bed, normal temperature elevator, traveling machine and PVC tray friction conveying system in the coating workshop of this project, including NORDBLOC.1 series coaxial helical gear motors and UNICASE series of right-angled shaft bevel gear motors and other products. 1/3 NORD drive for project painting line

Application scenario 1: Provide strong power for the walking roller bed in the painting workshop In the selection process, relying on rich industry experience, NORD provided the NORDBLOC.1 series coaxial helical gear motor for the walking roller bed in the workshop. This geared motor with smooth surface is an innovative drive solution for applications with high demands on cleanliness. This patented innovative coaxial geared motor does not have any open slots, which significantly improves the stability of the product, and at the same time makes the surface smoother, effectively preventing the accumulation of solidified liquid or solid material. In addition, its aluminum housing is not only strong, but also light in weight, which is convenient for users to install and maintain. In the process of operation, the efficiency is as high as 95%, which reduces the cost, and the high axial and radial bearing capacity ensures the reliability of operation.NORD drives for project painting lines

Application Scenario 2: To meet the special requirements of the PVC pallet friction conveying system NORD also configured the NORD De’s unique VL configuration can effectively improve the radial bearing capacity of the output shaft and ensure the normal operation of the tray friction conveyor line.NORD drives for project painting lines

Application scenario 3: Guarantee the reliable operation of the elevators in the paint shop. The car paint shop often uses elevators to complete the operation. For this reason, NORD provides UNICASE series right-angled shaft bevel geared motors for these elevators. This classic NORD bevel geared motor with a torque range from 180 to 50,000 Nm is durable thanks to its compact UNICASE cast iron housing and is suitable for lifting applications. In addition, the bevel gear motor takes up less installation space and has the same configuration as the travel drive, which meets the needs of users. It is worth mentioning that NORD can also provide professional configuration solutions for process roller bed applications that require explosion-proof motors. 2/3 NORD drives for project painting lines

NORD provides a series of drive solutions for automotive painting and conveying equipment, which have not only been recognized by users, but also favored by more and more domestic automobile factories.

Conclusion: Perfect product selection to meet the production needs of the automobile industry We see that future automobile factories will pay more attention to trends such as green, low-carbon and sustainable development. As one of the world’s professional drive technology manufacturers, NORD is committed to providing professional technical solutions for customers in the automotive industry, and has launched more and more new energy-efficient products. For example, NORD’s latest innovative DuoDrive geared motors are compact and have an IE5+ high energy efficiency class, which can be matched with NORD electronic drive equipment to meet high power requirements and excellent system efficiency. Relying on rich industry experience, NORD has successively participated in many automobile projects, from joint venture brands to self-owned brands, from traditional fuel vehicles to new energy vehicles, NORD follows the development of the industry, and satisfies different needs through innovative products and perfect selection Apply requirements and empower projects with more mature practical experience.
