With the rapid development of construction machinery and automotive fields, its production mode is gradually moving towards automation and high-speed direction, the industry on the stability of equipment operation, high-speed transmission speed, structural design flexibility requirements are becoming more and more stringent. In this context, manufacturers are constantly seeking change, including one of the world’s top 500 companies in the field of construction machinery. The company opened a new industrial park at the end of last year for the large-scale production of heavy truck vehicles, diesel engines and other core industrial chains and a new generation of construction machinery to create a world-class model of “intelligent manufacturing”. Among them, NORD provided safe, reliable, energy efficient drive technology solutions for the project.
Difficulty of the project: painting workshop process is complex, high quality requirements

As a benchmark project of intelligent manufacturing, the industrial park faces many difficulties in the construction process. Under normal circumstances, vehicle manufacturing is divided into four major processes: stamping, welding, painting and final assembly. Among them, coating belongs to decorative and protective multi-layer coating, which is a process with more processes and higher quality requirements in automobile manufacturing. In addition, the painting workshop also needs to control temperature, humidity, pressure, flow and other process parameters in the production process, these process flows are pipelining operations, and the conveyor system is needed to achieve between the upper and lower processes. Therefore, in the modern automobile coating 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 improvement of production capacity.

Solution: Tailor-made drive system ensures high-speed, smooth, safe and reliable coating process

At present, the mechanized conveying system of the painting workshop of the project is composed of air and ground conveying equipment. The main task is to ensure the pre-treatment, electrophoresis, body drying, sealing, spraying and other processes of various types of white body and parts in the painting workshop, and send the qualified body to the conveying line of the final assembly workshop. The conveying equipment mainly includes air ground conveyor, ground chain, rolling bed, elevator, positioning mechanism and so on. Among them, the rolling machine is widely used because of its easy maintenance and easy speed control. In order to ensure the rolling machine and other conveying equipment running at high speed and smooth, accurate positioning and safe and reliable, easy maintenance, after the preliminary selection of the project, NORD uses professional verification software NORDcalc to check the fatigue strength and yield strength of the internal bearings and gears of the reducer, so as to select the product model with the ideal speed ratio. In the end, NORD supplied nearly 500 drives for high-temperature power rollers, room temperature elevators, transporters and PVC pallet-type friction conveying systems in the painting workshop, including products such as the NORDBLOC.1 series coaxial helical gear motor and the UNICASE series direct shaft bevel gear motor. 1/3 of NORD drives are used in the project painting line

Application Scenario 1: Powerful power for the walking roller in the painting shop During the selection process, NORD relied on its rich industry experience to provide the NORDBLOC.1 series of coaxial helical gear reduction motors for the walking roller in the workshop. With a smooth surface, the retarder motor is an innovative drive solution for applications where cleanliness is required. This patented innovative coaxial gear motor does not have any open holes, significantly improving the stability of the product, while making the surface smoother and effectively preventing the accumulation of solidified liquid or solid materials. In addition, its aluminum housing is not only strong, but also lightweight, which is easy to install and maintain. In the operation process, the efficiency is up to 95%, reducing the cost, and the high axial and radial load capacity ensures the reliability of the operation. Nord drives are used in the project painting line
