Fanuc robot in Rolls Royce's "ace factory" is located in inchinnan Town, Renfrew, Scotland. It is the global manufacturing center of Rolls Royce, the world's second largest civil and defense aero engine manufacturer. It is the same as "noble in luxury cars" Rolls Royce, and its pursuit of manufacturing high-quality products is the same. "Ace factory" adopts two highly integrated fully automated forging production lines to build the most famous gas turbine compressor. The two production lines use six FANUC robots respectively, which multiplies the production efficiency and ensures the synchronization and stability of the whole casting process
the target of achieving less scrap rate and double production efficiency on the working cycle of 24*5 working metal price higher than its marginal cost was approved. During the progress of the project, problems were soon found: at the beginning of the process, the operator can synchronize with the robot, but when repeating the production action in front of the furnace at more than 1000 ℃, the cost to make the operator keep up with the high-speed production beat is twice the income brought by the robot
fanuc company was again invited to carry out fully automated transformation of the whole production line, and provided system simulation to Rolls Royce for evaluation in advance
the whole system starts from pre forging and final forming, which are the two most critical stages of the casting process, and completes the transition from the green body to the finished product of the wing compression engine. Fanuc robot UK is responsible for the improved design, delivery and system integration of all production equipment, and integrates the control and management of the system into the controller of FANUC robot
first, a FANUC m-710ic/50 robot grabs the blank from the tray of the conveyor belt, puts it into the furnace for heating, takes it out after reaching the set temperature, and puts the heated blank into the first mold. At this time, the robot sends a signal to start the forging and forming process. Next, the robot clamps and installs the riser on the forging, and puts the forging into the second die for preliminary forging. After preliminary forming, the robot takes out the forgings and puts them into the picking workstation for the next operation - shot blasting
in order to meet the requirements of full automation, the processing equipment used has been redesigned by FANUC company. Rolls Royce develops new dies to ensure that the forging (or extrusion) process is carried out in the bottom die
before shot peening the forgings in the picking workstation, another important step needs to be done by the FANUC small robot LR mate200ic installed on the back of the stamping die. Namely, blow away the iron filings on the surface of forgings and spray a layer of graphite lubricant. Graphite spraying is the key to ensure the consistency of product quality. If there is too much graphite on the tool, it will affect the structure of forgings. The robot can accurately control the dosage and spraying surface. The automation of graphite spraying process shows that stable operation can bring huge benefits
shot blasting is led by a FANUC m-20ia robot. It clamps the forgings and puts them under two nozzles, which spray high-speed steel sand to clean the forgings. Then, the robot places the processed forgings on the conveyor belt and enters the final forming stage
the first step of final forming starts from coating forgings with glass coating by 2020. A FANUC m-710ic robot installed on the linear slide rail with an upside down crane locates the forgings transmitted, and uses the electrostatic spraying process to complete this operation. Rollsroyce's project development team found that electrostatic spraying is more uniform and stable than previous manual operations
next, the m-710ic robot will put the forgings with glass coating into the forging furnace for heating, take out the qualified heated forgings and transfer them to the forming press for forging. Finally, the graphite lubricant is sprayed by the small robot LR mate200ic, and the final forming process is completed
pay attention to the cleaning of the formed turbine blades, which are put into the trimming press by the m-710ic robot for cutting and trimming, and then transmitted out through the immersion cooling tank. Through the positioning of FANUC IR vision vision vision vision system installed in the immersion cooling tank, another m-710ic robot grabs the finished product and puts it on the tray
finally, when the tray is full of 100 blades, the robot will lift the tray and stack it at the specified position to complete the whole process
Rolls Royce and the alloying of the base metal affirmed the huge benefits brought by the automated casting system in the evaluation: higher efficiency, double productivity, better quality and achieving the goal of "one step". The synchronization of the whole automatic production line frees rollsroyce from multi-stage forging. It only needs to spend a little more time on shot peening to produce higher quality products. In addition, the number of jobs required in the foundry has been reduced
fanuc is the world's most diversified manufacturer of FA (factory automation), robots and intelligent machinery. Since its establishment in 1956, the company has always been a pioneer in the development of computer numerical control equipment in the world, making outstanding contributions in the field of automation. In the 1970s, FANUC became the largest professional CNC system manufacturer in the world, accounting for 70% of the global market share. In 2008, FANUC became the largest robot manufacturer in the world, and it was the first robot manufacturer in the world to exceed 200000 robots. At present, it has exceeded 250000 units, and its market share ranks first. (end)
