Combined stretching method of spiral blade

Spiral blades are used to convey relatively viscous and compressible materials. It belongs to a kind of blades with hard texture and excellent performance. The forming method of spiral blades is usually stretch forming. The following describes the stretching of the blades. Forming method:
1. When the single-piece and small-batch production is performed, the spiral shaft 2 is placed on the base of the workbench or on the steel plate, and the lower end is fixed on the base.
Second, the blade blank CD slitting pry along the radial direction, according to the application of the spiral rotation direction on both sides, the extension distance is greater than 3 times the thickness of the blade is blank but less than about 10 to 20 mm, so that all blades are welded into a string.
3. The beginning of the blade is formed by a single-chip microcomputer. The helical spiral is connected with the welding, and there are blades on both sides of the welding joint. During the welding process, the plastic deformation speed is accelerated due to the deformation of bad areas such as local heating of the welding and welding flame.
4. When each spiral blade should pay attention to the outer spiral axis of the line edge closely, this is because the inner hole of the outer circle of the blade spiral axis determines the blade spacing. When the blade is in the same size as the water ruler, the blade's spiral axis is fixed.
Fifth, unloading semi-processed workpieces, symmetrical and intermittent welding is generally used according to the welding drawing; when the welding angle is 4 mm, a small current and a small diameter electrode are needed to minimize the deformation of the screw shaft caused by welding.
6. During operation:
1. Do not allow the limbs and other objects to discharge the door through the valve box. Thoroughly clean the hopper, delivery elbows, valves, pistons and delivery pipes.
2. Check that there is no mortar residue at the bottom of the S valve. In the slurry conveying pipe, do not open the conveying pipe without pressure. During the lubrication process, the equipment should be closed to avoid mechanical damage or personal injury.
The spiral blade is a spiral surface type, and has the functions of stirring and mixing materials. The combined stretch forming method is simple in operation and easy to understand. It is one of the more widely produced nowadays, and its performance is constantly changed to enhance safety.
