RusAutoNewsCom.- Avtovaz has shared the details of the modernisation process in 2020. As reported by Volzhsky Car Manufacturer newspaper, the launching of the EoL (End of Line) process can be considered as the biggest project of 2020, in the field of car production. Tests on finished vehicles are conducted more thoroughly and at a lower cost, thanks to the introduction of a new test track and other technologies.
Modernisation projects have been implemented in several areas of car production. Such works have been carried out on PAP B0 for example: robotics and process optimisation. Nine robots have been installed on the chassis and body welding lines, alongside the two robotic lines for sidewall welding (36 robots in total). Another 12 robots have been mounted in the form of robotic cells for the welding of the bulkhead and the central floor. All these operations helped improve the geometry and the quality of the body as a whole.
Manipulators have been introduced at the posts for the installation of wheels, gas tanks and rear seats in the production of PAP B0 assembly, which increased the convenience of operations. Two flows of automated carts (AGV) have been launched to automate the flow of parts from warehouses. The carts are involved in the delivery of the instrument panel traverse to the assembly line, as well as accessories and interior parts from kitting to the conveyor.
A project on the organisation of the kitting area and the delivery of components on the line using automated trolleys has been implemented in the production of Lada Granta vehicles in 2020. The dashboard assembly line has been moved to the interior line for the optimisation of the production process. This move has made it possible to free up the area for logistics tasks, reduced both stocks and the losses on operator movements and improved the ergonomics of work posts all around.
The cataphoresis body accumulator has been modernised along with the installation of a new tempering section, in order to increase the efficiency of the painting process of Lada Granta, which resulted in the improvement of the production programme consistency by 20%.
Eight injection molding machines have been modernised in the production of plastic parts, through the replacement of worn-out robots for the removal of parts. The mounting of new robots has improved the productivity of the equipment: the cycle of the injection molding machine went down by 7-12 seconds.
Five stations have been introduced to PPI as well, for preheating the hot channel of molds, which reduced the changeover time from 35 to 20 minutes. Taking into account the fact that 2-3 changeovers are performed on each injection molding machine per day, the modernisation has led to an increase of 2-3% in the productivity of equipment.
Improvement works continued on the consumer properties of manual transmissions, as part of gearbox production in 2020. The design of the 6-speed gearbox has been changed from the 1st to 4th gear, as well as the synchroniser couplings of 3rd, 4th and 5th gears. New technological equipment, cutting and measuring instruments were put into operation in spring: 9 positions of cutting tools, 9 machine tools and 30 calibres were manufactured and 28 units of technological equipment were re-equipped in total. In addition, capacity improvement works continued in engine and gearbox production, alongside the localisation of the individual parts of power units.
Works on the improvement of the environmentally-friendliness of technology have also continued in 2020. For example, 24 million rubles have been spent on the replacement of 16 hydraulic filters in air purification ventilation systems at iron casting and forging workshops.
