The use of automatic checkweighers in the processing of auto parts and components-reasonable control of product costs and improvement of product quality

The application of Guangdong kenweigh automatic checkweigher machine in the field of auto parts processing-reasonable control of product costs and assist in improving product quality. Auto parts are the basic modules that constitute each part of the car. With the development trend of my country's economy and the obvious increase in the level of gross national product, cars have become the preferred means of transportation for more and more people. And the auto parts field has also gained prosperity and development trend with the increase in the demand for cars in our country. High-quality auto parts products can not only help auto parts companies reduce product costs, but more importantly, ensure the quality of car products. Guangdong kenweigh high-tech produces a variety of models and specifications of automatic checkweighers, fully considering the requirements of car parts processing companies. The net weight of forged products of auto parts is generally related. A car is composed of fifteen components such as the car body, the compartment, 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 for assembled cars continue to increase, and the regulations on the steel castings of matching auto parts are also getting higher and higher. Steel castings are product workpieces or blanks obtained by forging and processing of metal composite materials. 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 of the transmission system in the axle box, etc., Both are important steel castings related to the safe operation of automobiles. If calculated by the net weight, 17-19% of the components on the car will use steel castings. During the processing of steel castings, it is stipulated that one piece is consistent, without all porous structures, unnecessary indoor spaces, inclusions or other defects. The components manufactured in this way must achieve a relatively high ratio between the compressive strength and the net weight in order to obtain a stable safety factor. According to the current international standards, the net weight tolerance of crankshaft steel castings generally needs to be controlled within 2%. For auto parts manufacturers, in addition to ensuring productivity, they are also very concerned about the quality of parts products, because the quality of auto parts is a prerequisite for ensuring the safe operation of automobiles. The shortcomings of manual net weight inspection are due to the high requirements for forged products of auto parts (that is, it is stipulated that a piece of forged products are consistent, and a certain net weight ratio must be achieved). In the processing process, manufacturing companies generally use weighing methods , Carry out net weight inspection on commodities to remove unqualified products. In the past, the net weight inspection of auto parts was carried out according to the method of human inspection, that is, after the laser cutting production process, the finished product was manually weighed by the actual operation staff, and then the components were classified according to the net weight specification . Due to the complete manual 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 checkweigher enters the automotive industry for manufacturers with a high degree of mechanical automation in the processing process, and it is preferred according to the net weight of mechanical automation. Many years ago, Guangdong Kenweigh, one of the largest auto parts manufacturers in Europe, just started to care about the problem of how to reasonably control the net weight of auto parts. Ford's Walker forging and processing plant uses hot forging to manufacture 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 run to the middle and downstream processes for re-production and processing. In order to better achieve the net weight specification, that is, to keep the net weight error of the rough steel within the allowable range, Ford Walker added an automatic checkweigher after the laser cutting process to remove the unqualified net weight products from the production line. At this stage, in China, no matter whether it is a production line or a semi-production line, auto parts manufacturers are increasingly aware of the necessity of net weight control. With the goal of increasing productivity, auto parts manufacturing companies have just begun to introduce automated technical steps to replace the current human inspection process. Many auto parts manufacturers in China are dominated by the production and manufacture of automobile connecting rods. This product has the following main characteristics in terms of relative net weight inspection products: ■The product is based on low volume ■The length of the product itself is longer and irregular ■The product is relatively long It is very easy to cause damage to the transmission belt. ■It must be classified according to the net weight. Guangdong kenweigh high-tech automation technology solutions. For the above product characteristics, Guangdong kenweigh high-tech produced the BDCW-T series of automatic checkweighers to consider customer requirements. ■The quantity of goods is not high, so customers have more room to choose models and specifications, and a lot of consideration will be given to the main performance of the characteristics of the automatic checkweigher itself. ■The automatic checkweigher of the BDCW-T series shows a unique specification of the input/output section, and the side clamping transmission belt is added to ensure that the longer forging safety products are accurately based on the weighing section. ■The transmission belt of 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 dismantling and replacing the transmission belt. ■Consider the rules for net weight classification based on the presentation of several net weight system partitions.
