1. The press body material is made of ductile(nodular) iron, which is more resistant to pressure and wear than general gray cast iron, especially resistant to vibration, improving stamping accuracy and service life.
2. Design structure of Separated clutch and brake is more stable and scientific than integrated clutch brake.
3. Adopt oil lubrication system introduced from USA, fully guarantee the high-speed lubrication requirements, more stable and safe.
4. The slider uses eight-sided ball bearing guide, higher precision, easy to adjust and repair.
The company occupies an area of 30,000 square meters and builds a modern large-scale industrial plant. (The company has a large-scale precision casting company) with large-scale automated production technology and processing equipment, a strong team of engineers, perfect quality control and inspection system, ensuring The quality of each stamping equipment. Over the years, Guoyi has developed a new generation of high speed precision press machines through independent innovation with German technology. Our company’s fist products GYH 30T-500T, GDH 85T-300T, GYC 25T-85T series high-speed precision automatic press, play a decisive role in new energy vehicles, smart equipment, household appliances, hardware electronics and other industries.
Our equipment is packaged in containers and transported by sea.
Because the inertia force of High speed press is too large, when using pneumatic balancing cylinder, its size is too large, the slider speed is too high, its pneumatic seal ring can not bear, the upper and lower chambers of pneumatic balancing cylinder need frequent intake and exhaust, there is no suitable pneumatic valve to meet this too fast commutation frequency, therefore, the inertia force balancing mode of pneumatic balancing cylinder is not suitable for High speed press.
The inertia force of crank-slider mechanism includes three parts: centrifugal inertia force produced by crankshaft rotation; reciprocating inertia force produced by slider reciprocating motion; and inertia force produced by connecting rod plane motion. Among them, the inertial force produced by the planar motion of the connecting rod is the most complex. In this project, the mass of the connecting rod is transformed into the hinge point of the connecting rod and the crank pin by the two-mass substitution method according to the static equivalent condition, and then the rotary inertia force is calculated by combining the connecting rod with the crankshaft. In addition, a special dynamic vibration protector composed of springs is installed in this project to prevent vibration from being transmitted to the base of the press.China Straight Side High Speed Press manufacturers
