The application of Zhongshan Smart weigh automatic multihead weigher in the auto parts processing industry-effectively control production costs and help improve product quality Auto parts are the basic control modules that make up every part of a car. With the development trend of my country's economy and the obvious increase in the level of the people's gross national product, the car has become the choice means of transportation for more and more people. The auto parts industry has also gained a strong and developing trend with the increase in the demand for small cars in China.
High-quality auto parts products can not only help auto parts companies reduce production costs, but more importantly, ensure the quality of car products. Zhongshan Smart weigh provides automatic multihead weighers of various specifications and models, and fully takes into account the regulations of car parts processing companies. Net weight relationship of forged products of auto parts In general, a car consists of fifteen prefabricated components such as body, trunk, diesel engine, front axle assembly, rear axle, windows, gearbox, drive shaft, and car steering system. constitute.
With the development trend of China's auto industry, the parts required to assemble cars are constantly increasing, and the requirements for stainless steel castings for matching auto parts are also getting higher and higher. Stainless steel castings are commodity product workpieces or blanks obtained by forging of metal material polymer materials. The characteristics of stainless steel castings for cars are complex modeling design, relatively light net weight, standard deviation of working conditions, and high safety factor requirements.
For example, the crankshaft, engine crankshaft, and diesel engine camshaft used in diesel engines, front beams and steering rods necessary for the front axle assembly, rotating shafts and flexible waterproof casings for rotating shafts used in the rear axle of automobiles, and Transmission gears, transmission gears, etc., are all key stainless steel castings related to the safe operation of automobiles. If calculated by net weight, 17-19% of the prefabricated components on the car will be stainless steel castings. In the production process of stainless steel castings, it is required that one piece is consistent, without all porous materials, redundant interior space design, carry-on or other defects.
For electronic devices produced and processed according to this method, a high ratio must be guaranteed between the tensile strength and the net weight in order to obtain stable safety performance. According to the current global level, the standard tolerance of the net weight of stainless steel castings of engine crankshafts generally needs to be controlled within 2%. For auto parts manufacturers, in addition to ensuring production efficiency, they are also very concerned about the quality of parts and components, because the quality of auto parts is a necessary condition to ensure the safe operation of cars.
Defects in Human Resources Net Weight Detection Due to the high requirements for forged products of auto parts (that is, a piece of forged products is required to be consistent, and a certain net weight ratio must be guaranteed), in the production process, the processing and manufacturing industries generally pass the weighing method. In this way, the net weight of the product is tested to remove the unqualified products. In the past, the net weight detection of auto parts was carried out based on the method of human resources detection, that is, after the production process of fiber laser cutting, the product output was weighed by hand by the operator during the operation, and then according to the net weight standard. Prefabricated components are classified. Because the operation process is completely dependent on human resources, it is easy to cause deviation and inaccuracy in the whole process of net weight classification, and the efficiency is high and low. The immediate result is an increase in manufacturing costs, and there is also a certain amount of product output and quality. Security Risk.
Automatic multihead weigher enters the automotive industry For manufacturers with a high level of electrical automation in the production process, the selection is based on the net weight of electrical automation. Many years ago, one of Europe's largest auto parts manufacturers——Zhongshan Smart Weigh started to focus on the difficulty of how to effectively control the net weight of auto parts. Zhongshan Smart weigh uses hot forging to produce and process important prefabricated components in the gearbox. In the production process, the rough steel is first cut into cylindrical bars of a certain length, and then it runs to the middle and upstream production process for production and processing.
In order to ensure the net weight standard, that is, to make the net weight deviation of the rough steel within the allowable range, Zhongshan Smart Weigh adds an automatic multihead weigher after the fiber laser cutting production process, and removes the products with unqualified net weight from the automatic production line.
