Improving bevel processing methods is the premise and key to improving welding quality. How to improve bevel processing methods and improving bevel processing quality is an urgent task before construction enterprises. The groove is cut with a mechanical cutter, the groove end face is smooth, the thickness of the blunt edge is uniform, the groove angle is accurate, the steel is not easily oxidized, and the groove processing speed is fast, the efficiency is high, and the cost is low.
The working principle of the pipe beveling machine is: the power is transmitted from the motor to the gearbox through the coupling, and then to the main shaft from the speed change mechanism, and finally the power is transmitted to the cutter head to achieve the main motion required for cutting metal; The cutter mechanism moves the cutter head forward, and continuously increases the cutting of the pipe by the blade, so as to realize the processing of the pipe groove.
The groove form of the steel pipe nozzle is generally required to be V-shaped. If the groove is processed according to the principle of lathe cutting, it is necessary to fix the tool to rotate the workpiece, and it is difficult to make the whole steel pipe with a length of 6-12m rotate smoothly and at a constant speed.
In order to achieve the processing of long pipe grooves, the groove machine is designed to fix the workpiece and rotate the tool, the cutter head is a cone disk end face cutter, and the movement path of the cutting edge is tapered to meet the shape of the groove to achieve rotary cutting Purpose. Because the form of the cutter is a face turning milling cutter, to avoid the chipping phenomenon caused by the tool tip not passing through the center of the workpiece when turning the face, take the blade inclination angle Ks = 0 and ensure that the secondary edge has a certain clearance angle. The material of the steel pipe for processing the groove is generally 20 # carbon steel. Considering that the machine is suitable for carbon steel of different steel grades, the wear resistance and bending strength of the tool should be improved. The tool material should be YT steel.
Valve Bags has the characteristics of improving packing efficiency, convenient transportation, strong strength and low breakage rate.
Valve bags classification
Valve bags can be divided into: pp valve bags ,Pe Valve Bags, Paper Plastic Compound Valve Bags, kraft paper valve bags and multi-layer kraft paper valve bags. Valve bags can be divided into: upper open valve pocket, lower open valve bags, upper and lower open valve bags.
Valve bags application.Valve bags is mainly used for packaging powder, chemical powder, chemical fertilizer, synthetic materials, explosives, grain, salt, minerals and other powder or granular materials and flexible materials. Especially suitable for high-end products, can improve the packaging level of products.
