Innovation in the automatic feeding and setting device for steel drum production Text / Mubo (Yingkou North Barrel Equipment Technology Co., Ltd.) With the development of the world economy, the demand for steel drums is increasing day by day, and users have put forward higher requirements for the quality of products, thus promoting the technological progress of the steel drum manufacturing industry and promoting the rapid development of the industry. At first, the domestic barrel production line mainly used manual and semi-automatic equipment. Due to its low efficiency and low product qualification rate, it seriously affected the service life of steel drums. In recent years, China began to pay attention to the technical development of automatic barrel production lines. Steel drum manufacturers have also begun to install automated production lines, and the share of automatic steel drum production lines in barrel making equipment is also increasing. In the manufacturing process of the steel drum, the steel billet is cut to the specified size after being cut and calibrated. The shearing is the length of the steel sheet. If the width of the steel sheet does not meet the requirements, the finished product is affected. The quality and specifications of the barrel, the existing fixed-size device needs manual adjustment, the size error is large, the operation is cumbersome, and the raw materials for the fixed length cannot be optimized for cutting, there are serious shortcomings of raw material waste, the production efficiency is low, and it is not conducive to automation. The operation of the production line. To this end, our company independently developed an automatic feeding fixed length device. This equipment is through the front automatic loading platform, automatic feeding platform, automatic feeding robot, automatic feeding belt line, automatic feeding shearing machine. The stacked barrel body is transported to the automatic feeding fixed length device, adjusted to the required size by the servo motor, the size of the cutting board is precisely controlled, the production efficiency is improved, and the degree of the automated production line is improved. The automatic feeding fixed length device is the main equipment of the steel drum automatic unloading and cutting width cutting equipment production line. The efficiency and precision of the fixed length have important value for the steel plate. At present, the fixed length equipment produced at home and abroad mostly adopts the mechanical fixed length. Or manual lengthening, so the practical solution of the automatic feeding fixed length device is extremely urgent for the demanding steel drum manufacturers. First, the research and development direction of automatic scale device The automatic feeding fixed length device is a special equipment for ensuring the size of the blanking. The blanking is the first process of steel drum production. The size and precision of the blanking directly affect the normal production of the subsequent process, thus affecting the quality of the steel drum. Whether the cutting is reasonable or not is directly related to the level of material utilization and the level of scrap. Therefore, the blanking process should receive sufficient attention. The automatic feeding fixed length device is one of the equipments in the steel drum automatic unloading and cutting width cutting equipment production line. In the manufacturing process of the steel drum, the raw material cutting process preparation includes unwinding, leveling, shearing, punching, etc. Process, this is the first step in the production of steel drums. It has a great influence on the production and product quality of the downstream process. The length and width of the material can not be exceeded. The error will affect the subsequent process and even cause waste. The shape error should not be too large. For the barrel blanking, in addition to ensuring that the length and width dimensions are not out of tolerance, the shape should not be too bad. The normal blanking shape should be rectangular, and the out-of-tolerance blanking often becomes a parallelogram. Trapezoidal, etc. The process requires the corners of the web to be 90 degrees. In order to facilitate the measurement, the difference between the two diagonal lengths is generally used as the shape error test standard. When the width of the raw material steel plate does not match the finished barrel process specification, the molding process needs to cut the width of the steel plate to the required size to ensure the quality and specifications of the finished product. The automatic feeding and setting device is not only an important process of the production line, but also a highly automated device. With heavy-duty structural design, the servo automatically adjusts the length of the fixed length, with stable performance and low noise. It is practical, durable, low cost, low operating cost, reasonable layout, convenient logistics flow, minimal floor space, and convenient use and maintenance.
