Development of automatic steel barrel weld rolling machine Text / Mu Deping After the seam of the steel barrel is welded, the overlapping part of the weld will have high and low protrusions, which not only affects the appearance, but also affects the quality of the sealing of the bottom cover and the barrel. Since it is a two-layer steel plate lap welding, In theory, it is twice the thickness of the steel plate. It is difficult to achieve seven-layer round curling at this position when it is wound, which is usually easy to cause leakage. In addition, when the steel drum is screen-printed, the welded part is easy to scratch the wire mesh and affect the production. . At present, domestic steel drum manufacturing enterprises basically do not use the weld flattening process, which is obviously unable to meet the requirements for customers who are increasingly demanding. Our company has developed a self-welding rolling machine to flatten the welded seam of the barrel after welding, so that the welded seam after flattening can be close to the thickness of one steel plate, and the problem of thickening of the steel plate at the seam welding is solved in one fell swoop. To fill the domestic gap. I. Introduction to steel barrel welding seam rolling machine In the past, there was no related equipment for processing welds in China. Domestic steel drum manufacturers have always been dispensable for weld flattening technology. Generally, they can be sealed under simple grinding. Such a triangle is prone to be formed when sealing, which may cause defects in the steel drum such as poor sealing, which is disadvantageous for the subsequent process of the steel drum. The seam rolling machine can fill the gap in this field. The opportunity to flatten the welded steel barrel welds is a complete integration of the entire barrel body with uniform wall thickness and no sealing defects. The weld rolling machine equipment adopts heavy-duty structure design and adopts double-station design for high-speed barreling equipment. The welded barrel body is directly transported from the conveyor chain to the weld seam rolling machine, and the two barrels are flattened each time. Automatically flatten the steel barrel welds. The machine adopts PLC control system, configures color touch screen, realizes man-machine dialogue, monitors the whole process of processing, simple adjustment and convenient operation. The production line has a patent and has completely independent intellectual property rights. Technical innovation and main technical indicators: (1) weld flattening speed of 10 / min; (2) steel plate thickness after weld flattening ≤ 1.25 times; plate thickness of 0.8 ~ 1.2mm. Second, the main innovative technical features 1, the main technical parameters (1) Sheet: Cold rolled sheet σb<450Mpa (2) Sheet thickness: 0.8~1.2mm (3) Weld length: 800~1000mm (4) Barrel diameter: φ550～φ600mm (5) The thickness of the steel plate after the weld is flattened ≤ 1.25 times the thickness (6) Production speed: 10 / min (7) Power supply: three-phase 380V, 50HZ / 60HZ, power supply fluctuation +10% to 20% (8) Air supply: pressure 0.6Mpa, compressed air. (9) Cooling water: clean water, flow rate 6.3m3/h, pressure not higher than 0.1MPa, maximum inlet temperature 30°C. 2, the principle of control The machine adopts PLC control system, configures color touch screen, realizes man-machine dialogue, monitors the whole process of processing, simple adjustment and convenient operation. 3, the process (1) Steel drum production process Coiling → Unwinding → Leveling → Shearing → Reeling → Spot Welding → Seam Welding → Flattening Welds → Unloading of Barrels → Pulling Edges and Reinforcing Bars → Ripple W Bars → Crimping → Leak Detection → Degreasing → Washing → Phosphating → Washing → Cleaning and drying → Cooling → External painting → External spray drying → Storage (2) Weld rolling machine work flow Start → automatic feeding → roll round → servo push → sizing device → welding → flattening weld → unloading from the barrel → turning down the process 4, the main innovation, advanced (1) Welded roller rolling machine equipment adopts heavy-duty structure design, and adopts double-station design for high-speed barrel making equipment. The welded barrel body is directly transported from the conveyor chain to the weld seam rolling machine, and each time two flattening The barrel body automatically flattens the steel barrel weld. (2) Adopt PLC control system, configure color touch screen, realize man-machine dialogue, monitor the whole process of processing, simple adjustment and convenient operation. Third, the performance indicators are compared with similar domestic and foreign Domestic steel drum manufacturing companies basically do not use the weld flattening process, which is obviously unable to meet the requirements for customers who are increasingly demanding. Although there are weld bead presses in foreign countries, they are expensive, spare parts are purchased for a long time, and replacement is very cumbersome. The weld seam rolling machine developed by Yingkou North Baking Equipment Technology Co., Ltd. is used to flatten the welded seam of the barrel after welding, so that the welded seam after flattening can be close to the thickness of one steel plate, and the seam welding can be solved in one fell swoop. The problem of thickening of the steel plate has filled the domestic gap. For those who run a business in the catering and reatsurant industry, serving trays are of great importance. There are different uses for serving trays including carrying food and beverages from one place to another as well as enabling those in the industry to serve specific sized portions of food. Some serving trays are used to hold plates and drinks, while other restaurants choose the tray to serve food on. for sure; serving trays are an important part of the food industry.

When choosing serving trays for restaurant and catering businesses there are a lot of aspects to take into consideration. First, you will need to make a choice of the color and size of the trays. You can buy serving trays in many different sizes, ensuring that every establishment} can use the trays that are most appropriate for their business needs. When trays are used to be carried through walkways, they must be small enough to fit comfortably through doorways. If they are too big, waiters will find that it is difficult to transport food with these trays and the chance of spills and accidents will increase. The task that is being accomplished will best determine the type of serving tray that is going to be used.
Serving trays should in some cases be nice looking and provide a visual addition to the food that is being served on the tray. Additionally, many restaurants consider the design or shape of the tables when making their serving tray selections. This can be very important when placing the trays on the table. Ensuring that the trays make a good looking presentation for each meal is vital to a restaurant's success.
