Application of automatic multihead weigher in the field of auto parts processing

Author: Smartweigh–Multihead Weighter

The application of Zhongshan Smart weigh automatic multihead weigher in the field of auto parts processing-reasonable control of product costs and assistance in improving product quality Auto parts are the basic modules that constitute every part of a car. With the development trend of my country's economy and the obvious improvement of the level of GDP, cars have become the preferred means of transportation for more and more people. The field of auto parts has also gained prosperity and development trend with the increase in the demand for cars in my country.

High-quality auto parts products can not only help auto parts companies reduce product costs, but also ensure the quality of car products. Zhongshan Smart Weigher provides automatic multihead weighers of various models and specifications, fully considering the requirements of automobile parts processing companies. Generally speaking, a car is composed of fifteen components, such as the car body, the carriage, the diesel engine, the front axle assembly, the rear axle, the window frame, the transmission, the rotating shaft, and the automobile steering system.

Along with the development trend of my country's automobile industry, the parts and components required to assemble cars continue to increase, and the requirements for the corresponding steel castings of auto parts are also getting higher and higher. Steel castings are product workpieces or blanks obtained from metal composite materials after forging. The characteristics of car steel castings are complicated appearance design, light weight, poor working conditions and high safety regulations.

For example, the engine crankshaft, crankshaft, and engine camshaft used in the engine, the front beam and steering rod required by the front axle assembly, the transmission shaft and the transmission shaft waterproof sleeve used in the rear axle of the automobile, the transmission gear in the axle box, etc. All of them are important steel castings related to the safety operation of automobiles. If calculated by net weight, 17-19% of the components on the car will be cast steel. In the processing of steel castings, it is stipulated that one piece is all consistent, without all porous structures, unnecessary interior spaces, inclusions or other defects.

Components manufactured in this way must have a high ratio between compressive strength and net weight to obtain a stable safety factor. According to the current international standards, the dimensional tolerance of the net weight of crankshaft castings generally needs to be controlled within 2%. For auto parts manufacturers, in addition to ensuring productivity, they also pay great attention to the quality of parts and components, because the quality of auto parts is a prerequisite for ensuring the safe operation of vehicles.

The disadvantage of manpower net weight inspection is due to the high regulations on forged products of auto parts (that is, it is stipulated that a piece of forged product is consistent, and a certain net weight ratio must be achieved), in the process of processing, manufacturing enterprises generally pass the weighing method. , carry out net weight inspection of goods and remove substandard products. In the past, the net weight inspection of auto parts was carried out according to the manual inspection method, that is, after the laser cutting production and processing process, the actual operator will manually weigh the finished product, and then classify the components according to the net weight specification. . Due to the complete use of manpower for actual operation, it is very easy to cause errors and inaccuracies in the whole process of net weight classification, and the high efficiency is also low. The immediate result is to increase the manufacturing cost, and the quality of the finished car also has a certain degree. Security risks.

The automatic multihead weigher enters the automotive industry. For manufacturers with a high degree of mechanical automation in the processing process, the net weight of the mechanical automation is the best choice. Many years ago, one of the largest auto parts manufacturers in Europe——Zhongshan Smart weigh has just begun to care about the problem of how to reasonably control the net weight of auto parts. Zhongshan Smart weigh uses hot forging to manufacture the key components in the transmission. In the production process, the blank steel is first cut into cylindrical rods of a certain length, and then it is transferred to the mid-downstream process for reprocessing.

In order to achieve the net weight specification, that is, to make the net weight error of the raw steel within the allowable range, Zhongshan Smart Weigh adds an automatic multihead weigher after the laser cutting process to remove the unqualified products from the production line. At this stage in China, auto parts manufacturers who choose production lines or semi-production lines are increasingly aware of the necessity of net weight control. With the aim of improving productivity, auto parts manufacturing companies have just begun to introduce automated technology steps to replace the current human inspection process.

Many auto parts manufacturers in China are dominated by the production of automobile connecting rods. Compared with general net weight inspection products, this product has the following main characteristics: ■The quantity of the product is relatively low ■The length of the product itself is long and irregular ■The product is relatively short Heavy, it is very easy to cause damage to the transmission belt. It must be classified according to the net weight. Zhongshan Smart weigh automation technology solution For the above product characteristics, Zhongshan Smart weigh provides the BDCW-T series automatic multihead weigher to consider customer requirements. ■The quantity of products is not high, so customers have more choices for model specifications, and the characteristics of the automatic multihead weigher itself will be largely considered. ■ BDCW-T series automatic multihead weigher provides input/output section with unique specifications, plus side clamping transmission belt, thus ensuring long forging safety products accurately according to weighing section.

■The transmission belt of the unique material can reduce the damage to the transmission belt caused by the forged goods in the whole process of conveying, and reduce the frequency of replacing the transmission belt. ■ Consideration of provisions for net weight classification by presenting several net weight system partitions.
