Advantages Of Metal Stamping Parts

Shaoxing Huida Metal Factory | Updated: Jul 03, 2017

Advantages of metal stamping parts

1. The metal deformation condition is good, because when spinning wheel in contact with the metal close contacts, so contact area is small, the unit pressure is high, can reach more than 2500 ~ 3500 mpa, so spinning is suitable for processing high strength and difficult deformation of materials. Moreover, the total deformation force is small, thus reducing the attack rate. The tonnage of the rotary press machine is only about 1/20 of the tonnage of the presses.

2. With a range of products, according to the spinning machine has the ability to manufacture large diameter thin-walled tubes, special pipes, variable cross-section tube and spherical, hemispherical, elliptic, QuMu linear, and changes with ladder and wall thickness of almost all rotary system parts, such as rocket, missile and satellite of the nose and shell; Submarine osmotic seals and torpedo shells, radar reflectors and searchlight shells; Jet engine fairing and original motive parts; Hydraulic, compressor casing and cylinder; Turboshaft, nozzle, TV cone, combustion chamber cone and bellows; Rotary drum of dryer, mixer and washing machine; Shallow disk shape, disk shape, hemispherical head; Milk can and empty core of daily necessities.

The material utilization is high, the production cost is low. Compared with machining process, the rotary pressure machining can save 20% ~ 50%, up to 80%, and reduce the cost by 30% ~ 70%.

4. The performance of the products has been significantly improved, and the structure and mechanical properties of the materials after the spinning have been changed, and the grain size is small and the characteristics of fiber are formed. Tensile strength, yield strength and hardness are improved, the strength can be increased by 60% to 90%, while elongation decreases.

5. The surface roughness of the products is low and the dimension tolerance is small. The surface roughness of the general spinning processing products can reach 3.2 ~ 1.6 um, best can reach 0.4 ~ 0.2 um, after a lot of spinning can be up to 0.1 um. Spinning products can reach smaller wall thickness tolerance, such as phi 300 mm, the tolerance is 0.05 mm, 1600 mm, the tolerance of 0.12.

6. An important feature of metal stamping parts is the production of a seamless and seamless rotary hollow piece, which eliminates the discontinuity, strength reduction, brittle fracture and stress concentration of the weld.

7. metal stamping parts and sheet metal stamping, metal stamping parts can greatly simplify the process equipment, used by some need 6 ~ 7 times in stamping parts, spinning can be produced at a time, and metal stamping machine cheaper than ability the same stamping machine price in half.

The metal press is able to make overwide plates, and the basic method is to cut the cylinder of the screw in the direction of the bus. Abroad can spinning phi 2 m cylinder spinning machine is not a lot of equipment, use of this equipment is easy to make 6 m wide plate, but by enclosed with the traditional rolling method to produce 3 m wide plate need considerable mill. The United States with a metal stamping parts produced 7.5 m wide, long and 9 m ultra wide plank.

9. In the process of spinning, the defect of any slag, sandwich, crack and sand eye can easily be exposed due to the deformation of the spinning billet approximately by point. In this way, the spinning process also plays a role in the inspection of products.

10. Sources of billet is wide, can be used hollow stamping, extrusion, casting, welding parts, machining of forging and rolling billet and circular plate, and can spin titanium, molybdenum, tungsten, tantalum, niobium kind of difficult deformation of metal and other alloys.
