Instructions for use of steel bar straight thread rolling wheel
Author：
1. Product introduction: The thread rolling machine has the strength of independent processing, and can be processed according to the manufacturer's drawings. Among them, the rib stripping and rolling straight thread machine tool has the following features: it can directly set the normal thread and reverse the thread without changing the machine head; replace the blade and thread rolling wheel without dismantling the machine head; the threading efficiency is high, which is more than 50% higher than other models; It can be used at both angles of 60 degrees and 75 degrees. The product has the advantages of high precision, good effect and long service life, and is widely used in construction, highways, bridges, tunnels, culverts, industrial and mining industries. The thread rolling machine is a multi-functional cold rolling forming machine tool. The thread rolling machine can roll the thread, straight grain and oblique grain of the workpiece in the cold state within its rolling force range; the rolling of straight teeth, helical teeth and helical spline gears Rolling; straightening, reducing, rolling and various forming rolling. The machine has a safe and reliable electro-hydraulic execution and control system, allowing each working cycle to be selected from three modes: manual, semi-automatic and automatic. Then the thread rolling wheel is a tool that uses metal plastic deformation to roll out the thread on the thread rolling machine.
2. How to use the product:
1. The alignment of the thread rolling die is not correct, the rolled part has an axial displacement, and the tooth pattern is subjected to two stresses of shearing and extrusion;
2. The size of the thread blank to be rolled is uneven, the surface is not cleaned, and there are grinding wheel foam, scale and dirt;
3. The precision of the thread rolling machine is poor, the vibration is large, and it is in service under abnormal operation;
4. The thread rolling wheel must be fully demagnetized before leaving the factory, leaving residual magnetism, which will accelerate wear and failure due to the absorption of fine iron particles by the tooth lines during work;
5. Lubricant is not added during rolling, resulting in dry friction, causing the temperature of the cusp to rise sharply to exceed the tempering temperature of the rolling wheel, and the excessive tempering of the tooth pattern is softened, resulting in inverted teeth and stacked teeth failure
3. Features of straight thread rolling wheel:
1. Good alignment, stable performance and high joint strength.
2. Easy to operate, high energy saving, high material saving, high work efficiency, fast speed, no open flame, no pollution, not affected by the climate, and can be constructed around the clock.
3. It is not limited by the type and specification of steel bars, and has a wide application range of φ14-φ40mm.
4. The machine is small in size, light in weight, low in power consumption, and energy-saving.
5. It can be prefabricated and shorten the construction period.
6. Saving steel and good economic benefits.
4. The development trend of straight thread rolling wheel: The straight thread rolling machine is to adapt to the rapid development of the current construction industry and the increasing number of reinforced concrete structures, and to meet the requirements of a large number of steel bar connections. Our company Shanghai Hufeng Machinery Co., Ltd. successfully developed 、Developed a series of steel bar rib stripping rolling straight thread forming machines and connecting sleeves with international and domestic advanced levels, as well as steel sleeve tapping machines and car outer circle chamfering machines. The price is cheap and the quality is good, and has been well received by everyone.
