The first large-scale robot full automation and large-scale production line in China's heavy truck industry was successfully commissioned and officially put into use at the China National Heavy-duty Truck Group. Its successful development has rewritten the history of automation stamping lines applied only to the car industry and is a major leap forward in the technology of domestic heavy trucks.
Automation Dahong Line integrates the current domestic and international first-class automation control technology. Among them, the automated feeding system consists of 7 ABB stamping robots, Germany's advanced cleaning, and oil coating systems to ensure that the steel plate unpacking, cleaning, uniform oiling and other punching operations before the process flow smooth; hydraulic metal packaging system uses the ground In the pit structure, the process waste generated by the five presses is directly slid into the pit conveyor belt to the baler for compaction, transported out of the yard. The advanced control system of the entire production line makes the loading and unloading more intelligent, the track softer, and the movement accuracy higher. The system adopts the world's most advanced image recognition system to accurately position the sheet material, and the image of the sheet material is collected by the vision centering system to precisely adjust the orientation of the sheet material in the press to ensure the quality of the product. ABB is configured. The company's full-line monitoring system developed specifically for stamping automation, configures all equipment of the automation Dahong line at one point, and periodically backs up and saves the robot program to the database of the server through an advanced software system, while ensuring the safety of the equipment PLC program. , Can realize the automation of the press and the robot in parallel; the data storage function of the double table and control cabinet mold speeds up the mold replacement speed, automatic mold change across the line, making it possible to change molds while producing.
This automated dab line also leads the development of China's heavy truck industry to the forefront of science and technology development with its high efficiency, high precision, flexibility, full automation and safety.
Casting Thickening Sprue Tube Mainly applied to lost foam casting, mold casting, the traditional sand mold casting, coated sand casting, casting methods, to improve castings quality, reduce scrap, improve the quality of reclaimed sand, reduce the work intensity, etc. In China belongs to the first, it will be casting sprue tube of a revolution.
The main advantages:
1, light weight, easy to operate. Paper tube runner weight is only 1/10 of the same type ceramic tube runner weight, convenient operation, reduce labor intensity of more than 70%.
2, easy to cut, no pollution. Little dust paper knife cutting, cutting, greatly improve the intensity of labor and the environment.
3, good sealing, reduce risk into the sand. Interface using the socket type, not easy dislocation, interface closely, to avoid the sand into the sprue, effectively reduce the casting sand inclusion defects.
4, not with liquid metal. When pouring not crack, not adhesion, slag resistance, erosion resistance. Refractoriness is as high as 1460 ℃ above, solved the sprue adhesion problem for a long time.
5, the intensity is high, is not easy to damage. Room temperature compressive strength of 18 mpa, after repeated experiments, dropped below 1.5 meters high, will not damage.
6, for the castings without increasing carbon, carburizing. Ensure the casting material and performance is not changed.
7 and improves the quality of reclaimed sand, reduce equipment wear and tear. Paper after casting sprue tube blank, carbide waste few, about 1/20 of the ceramic tube runner, and easy to peel, easy clean, avoid the pollution of gating pieces of sand, and solved the ceramic gating pieces of sand reclamation equipment wear and blocking sieve, prolonging the service life of equipment.
8, energy conservation and environmental protection. Paper sprue tube with organic fiber and refractory materials such as waste paper as raw materials. Using process does not produce pollution, waste can biodegrade, is a typical green environmental protection, energy-saving products.
