[YesAuto Factory Secret] Speaking of Jingdezhen, the first thing that comes to mind is the “Porcelain Capital of the World”, and this is also the location of the headquarters of Changhe Automobile. As Changhe Automobile officially merged into BAIC Group in 2013, it will become one of BAIC Changhe's important production bases in the future. On December 27, 2015, with the official launch of the first Changhe Q25, Changhe Jingdezhen Hongyuan Factory was officially put into use, and I became one of the first to visit this factory. Today I will give you a brief introduction. This modern factory in the capital of Chinese porcelain.
BAIC Changhe Jingdezhen Hongyuan Factory is located in Jingdezhen City, Jiangxi Province, covering an area of about 3,600 acres. According to the plan of Changhe Automobile, the first phase of the Jingdezhen Hongyuan plant includes a stamping workshop, a welding workshop, a painting workshop and a final assembly workshop. Due to the limited time for this factory tour, we only hurriedly browsed part of the production lines in the stamping workshop, welding workshop and final assembly workshop.
First, we visited the stamping workshop of the factory. The workshop is designed with two stamping production lines, one uncoiling blanking line and one mold repair line, all of which are JIER stamping machines produced by Jinan No. 2 Machine Tool Group. At present, the factory has only opened one. High-speed stamping production line.
This production line consists of five-sequence punching machines. The first punching machine has a punching tonnage of 2,400 tons and uses Rexroth CNC hydraulic cushions. At present, the production line mainly produces exterior parts such as the body and door panels of Changhe Q25. It is understood that the stamping production line can realize automatic mold change, and the mold change time only takes 7 minutes. The production line can punch 10-12 times per minute. In addition, the single-arm robot from gudei, Switzerland, is used for loading and grabbing operations inside the press production line.
The stamped parts (the front door panel of Changhe Q25) also need to be manually inspected by parallel light, and then the qualified parts are neatly stacked on the shelf.
Next, we entered the welding workshop. At first glance, it felt a bit empty, because a flexible welding production line was built here in the first phase of the first phase of the project. In the future, as the factory continues to build and Changhe's new products are put into mass production, there will be Build other production lines.
The only flexible welding production line can realize the mixed-line production of four different models of body-in-white, with an automated productivity of 75%. At present, the main production of the body in white of the Changhe Q25 is here, and the trial production of another Changhe Q35 has also been successfully completed here.
Vehicle parts must first be manually welded to enter here, including chassis sub-assembly and side wall small parts. Here workers use welding torches to manually weld small parts to form large components such as the engine compartment and rear floor, and then send them to the robot welding station for further welding.
The robot welding station mainly includes the floor line, the left and right side wall lines, and the main body welding line. A total of 132 KUKA robots are equipped for welding operations.
After the car body is welded and assembled, it will pass through a door adjustment line, where the door components are installed. In addition, the welding workshop is also equipped with a three-coordinate measuring machine, which will conduct random inspections on the car bodies produced every day to eliminate unqualified products. However, due to time constraints, we were not able to visit this three-coordinate measuring machine for operations.
The welded body will be sent to the painting workshop, but due to the limited time of this visit, we did not visit this workshop. It is understood that there is a mechanized automatic flow production line built in the workshop, using the water-based paint 3C1B spraying process, and the emission is also in line National standard.
Finally, we came to the most important assembly workshop. This workshop with a construction area of 99,076 square meters is currently the largest single plant in Jiangxi Province. However, the workshop currently only uses less than half of the area, so it looks very empty. Due to time constraints, we only visited the co-car station in the workshop.
At the car-joining station, the parts assembled from the rear axle subassembly production line and the sub-frame into the production line will be transported to the bottom of the car body by the AGV automatic guided transport vehicle produced by Shenyang Sinsong, so as to facilitate the transportation of the parts in different stations .
When the AGV reaches the bottom of the vehicle, two operators will press the button that controls the elevator platform to raise the elevator platform upwards, and lift the rear axle and subframe to below the vehicle body, thereby reducing the difficulty of joining the vehicle. As Q25 is still in trial production (planning to produce 10 vehicles/shift on the day), we only saw one vehicle to be loaded that is undergoing joint vehicle operations.
After passing through the car-joining station, other sub-assembly lines will install front and rear bumpers, door tires and other components for the new car, and then come to the first inspection process-parallel light inspection paint.
Here, the staff will inspect the paint surface of the new car, and the parallel light channel is also a set of inspection methods adopted by major manufacturers. After this, the new car will also go through the rain room, brake inspection and other inspection links, so as to ensure the quality of the new car production.
In addition, a new energy trial production line is also designed in the final assembly workshop. However, the production line has not been put into production at present. In the future, as Changhe's products are enriched, the production line will also be used in the future.
Summary: Changhe Jingdezhen Hongyuan Factory has only passed 530 days from the foundation stone laying to the first model launch. With the completion of this modern factory, the products of Changhe brand will not be limited to the current small car products in the future. The new factory can satisfy the diversity Production of chemical products, such as SUVs and MPVs, and future new energy products.
Due to the very limited time for this visit, we just hurriedly browsed some of the production stations, and the Hongyuan factory has only completed the first phase of the first phase of the project. In the future, as the factory will be fully completed in 2020, this will have an annual output of 450,000 We will wait and see what the modern automobile production base will look like, and what the development of Changhe Automobile will be by then.
