What is steel barrel production process?

For the product structure alone, the steel barrel is a relatively simple product, as if people often say "not a junior version of the can." But in fact, a qualified steel barrel is required, but it must be completed through nearly thirty processes. The degree of control of each process is different, and the quality of the finished steel barrel is different. In particular, the process control of key processes is extremely important. At present, the separation of steel barrels and sealing are two types. Due to their different capacity and different use conditions, the degree of manufacturing is also different. When the regenerative production is used in the steel barrels of oil -loaded, the control requirements of each production process are higher. The following are about the process control points of the 200 -liter oil -packaged steel barrel production process. 1. The quality of the rough feeding, molding and other processes controls the grinding feeding, and the molding process includes: the appearance quality test of the barrel body, the bottom of the barrel, and the lid; Cut the feeding; the bottom of the barrel and the cover pre -roll spray; the bucket port on the barrel lid rivet, the segmentation process inspection, in the above -mentioned process, the main quality control points are: 1. The barrel body and the bottom of the barrel, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the cover plate, the lid plate, The appearance quality inspection of the material; that is, the material card, specification size, surface protection status and complete status of the barrel boards that are opened or packed are inspected and recorded. When you are defective, you should respond to the inspection department in a timely manner and deal with it as required. (China Golden Bag Network is the portal of the printing iron tank industry.) If the rust and defects are found during the cutting of the shear, it should be categorized and stored. After the batch task is completed It can be used to use the lane process. It is worth noting that if the rough and defective rough materials are mixed into the lower lane and the unlimited discovery, it will have a great impact on the quality of the product. 2. Pay attention to observing whether there are tear and wrinkles after the bottom of the bucket and the stamping formation of the barrel and cover; whether the bottom of the barrel, the size of the lid stretch in time should be drawn in time. The existence of the phenomenon of cracks will endanger the use of steel barrels; when wrinkles appear wrinkled at the bottom of the barrel and the edges of the lid, the rolling edge is increased and accelerated the wear of the rolling machine; The quality of the edge. 3. When spraying the bottom of the barrel and cover, first check the quality of the seal, that is, whether there is a deterioration, precipitation and other phenomena. In the phenomenon, the elasticity and contraction of the glue will change, which will also affect the sealing after the steel barrel curls. When the spray spray is not uniform or insufficient, it will also affect the curl quality of the steel barrel. Second, the quality control of the steel barrel welding and the quality of the seam welding process used to be in the past. Due to the design of the control circuit of the domestic steel barrel body, the design of the equipment itself was relatively backward, so that the point welding and seams of the steel barrel body welded and seams were Welding operation is more difficult, so it is listed as one of the key control processes. At present, with the reconstruction of advanced automated welding machines abroad, the use of computer programs has replaced artificial control to a large extent. In China, it tends to be stable. In the actual barrel welding and sewing welding operation, according to the material, thickness size, and overlap width of the material of the plate, the welding parameters are correctly selected and adjusted. Note that the overlapping volume of the point welding process must be controlled, otherwise it will have a great impact on the quality of the seam welding. Third, the quality control of steel barrels, edges, and cover -covered rolled forming processes are relatively easy to control the quality of the steel barrel and the quality of the edge process. When the molding part of the mold is high, its process size can remain relatively stable. It is worth noting that the size of the edge and the angle of the edge will also have a certain impact on the curl quality of the steel barrel. According to the relevant information and many years of work experience, the steel barrel blocking and curling process is a direct and difficult -to -control process. This is because it has appropriate adjustment factors in addition to the device itself. The size of the slot size, the shape size of the cover cover and the above processes, the size of the punch, the bottom of the barrel, the spraying control of the barrel, the welding of the barrel, the seam welders The control of the preface, the size of the barrel, and the angle of the barrel have a close effect on the quality of the rolled edge of the steel barrel. 1. The adjustment of the motion component of the device itself mainly includes the distance between the top disks between the two blocks and the working distance between the rolling wheels. Two or too small between the two blocks of the cover plate will affect the quality of the curl, that is, when the distance is too large, it may cause insufficient volume of the rolling edge. The distance may cause excessive volume or unrealistic phenomenon. The working distance between the rolling wheels is not appropriate, and the rolling edge may also occur, but these phenomena generally do not occur after the device debugs is normal. 2. Whether the size of the groove of the rolling wheel is the basis of the quality of the curls. If a set of curly wheels, the size of the rolled edge to be completed must be reasonable, and achieve a good curve coherence. Secondly, the shape and size of each rolling wheel should be consistent with the volume of the curl layer. There are defects such as incompatible or "shredded" and "double eyelids", especially when the bottom of the barrel bottom, covering and barrels is matched, in addition to the necessary theoretical calculations, reliability experiments should also be performed. Try to be as much as possible. Avoid the active behavior of similar sizes to ensure the curl quality of the steel barrel. 3. Whether the shape and size of the cover cover is also one of the important factors affecting the quality of the curl. The main factors are the size and angle size of the cover plate. If the outer diameter size is too large or too small, it will cause irregular shapes of the curl. The angle size will affect the normal play of the rolling rotor transmission, which will affect the quality of the curl. 4. In the case of high carbon content in the material ingredient, due to the high resistance of the material itself, the rolling edge forming is difficult, and the wear of the rolling wheels is accelerated, which affects the stability of the curl mass. At present, most barrel manufacturers have used such problems in the use of the barrels of the former Soviet Union in the process of use, which causes great difficulties to high -level drop tests. 5. The stretching height of the stretching size of the barrel bottom, the stretching size of the cover or the excessive width of the outside or too small will cause the impact of excessive material or steel barrel production process on the quality of the product ★★★ The production process control of the steel barrel Impact Author: Makou Tie Brother Article Source: China Golden Bags Click: 123 Release time: 2008-9-4 0:33:32 Insufficient materials and roll-up level disorders. 6. The purpose of spraying glue after the bottom of the barrel is to improve the sealing performance of the steel barrel and prevent the liquid in the barrel from leaking outward. When the amount of spray is too large, it will affect the number of rolls on the rolling edge. After the amount of spraying is over hours, the sealing effect cannot be achieved (especially when the volume of the rolling layer is insufficient). The sealing glue used for steel barrel curls should have good elasticity and high solid content. Seal effect. Sometimes in order to save trouble, the amount of material thickness specifications (unchanged sealing wheels) supplement curriculum rim -type groove volume is dangerous, and it will undoubtedly leave an inestimable hidden danger of quality. 7. The sealing of the point welding of the barrel body and the sealing of the seam welding on the steel barrel and the impact of the rolled side quality are interrelated, that is, the welding strength of the barrel welding is insufficient, which affects the quality of the bucket seam; When burning, the point welding at the sewing will leak; the overlap amount of the barrel welding control will affect the operation of the bucket welding. If it cannot be corrected in time Industry portal website) will have a edge lock response to the rolling effect. The welding thickness of the welding requirements (3.5-4mm) after the modified domestic sewing welding machine is close to the thickness of the plate, the quality of the curls is relatively stable, and the difference is unstable when the difference is large, especially the mechanical rotor seal cover curl edge edge edge The reflection of various phenomena is more prominent. 8. Control of the quality of each conversion process during the production process of steel barrels. The so -called conversion process mainly refers to the conversion of the barrel body and the bottom of the barrel, as well as during the process of the barrel. Anyone rolling, turning and manpower handling are used in mechanical rolling, turning and manpower. It is difficult to pass the acceptance. Therefore, many barrel companies use suspension transmission methods to avoid process conversion deformation damage when they understand this problem.
