Best rated bending press machine factory: The hydraulic press operates using the principles of fluid mechanics. A hydraulic press machine relies on Pascal’s law, which states that pressure applied at one point in an incompressible fluid is transmitted to other points with the same intensity. The hydraulic press comprises a couple of cylinders – a smaller one where the pressure is applied and a larger one where the force is exerted. The pressure exerted on the fluid in the smaller cylinder gets amplified in the larger cylinder, thereby creating a large force enough to press, shape, or form materials.

Mechanical stamping presses utilize a motor linked to a mechanical flywheel to power stamping operations. They generally provide pressing speeds between 20-1,500 strokes per minute and pressing capabilities ranging between 20-6,000 tons. They are generally used for high-volume progressive and transfer stamping operations. Mechanical servo presses use top capacity motors run by a link-assisted or direct drive system. They are generally used to produce complex parts in shorter periods than would be easy with hydraulic or mechanical machines.
What is the stroke rate per minute for stamping press machines? Mechanical presses use an electric motor which spins a belt linked to a flywheel. This is transferred via a series of gears. These gears drive the ram up and down. To begin the press, the flywheel is linked to a clutch and brake system which permits the flywheel to spin without actuating the ram at all. These mechanical systems generally run a lot quicker than others, with most presses capable of stamping the par 40-80 times in a minute. This rate is known as stroke per minute and it is an important factor in progressive tool design as it dictates how fast you can make your product.
The imprint bending is the same as the bending of the bottomed die, except that the front end of the punch is processed to the required bending radius, and the gap between the punch and the die at th bottom of the stroke is smler than the material thickness. Since enough presure approximately 10 timesof fee bendig is applied to force the front end of the punchto contact the material, springback is basically avoided.

Hydraulic press brake machines are divided ito manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. According to the synchronization method, hydraulic bending machines can be divided into: torsion axis synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization.According to the movement mode, hydraulic bending machine can be divided into up-moving typ and down-moving type.
As far as free bending is concerned, punch and die are procese at 85 or les (saler i better). When using this set of molds, pay attention to the ga beteen the male mold and the female mold at the bottom of the stroke, and the excessive bending that is sufficient to compensate for the springback and keep the material at about 90°. Generally, the springback angle of the free bending die on the new bending machine is s2, and the bending radis is equa to 0.156 times the opening distance of the die. For the bending of bottomed concave molds, the mold angle is generally 86 ~ 90°. At the bottom of the stroke, there should be a gap slightly larger than the thickness of the material between the male and female molds. The forming angle is improved because the bottomed die has a larger bending tonnage (about 4 times that of free bending), which reduces the stress that usually causes springback in the bending radius.
World Precise Machinery (China) is the biggest branch factory of World Group which is focusing on producing and technology researching of power press machines. The original factory was built in 1953 to produce small eccentric punching machines for new China industry. World Group bought this factory in 1998 and expanded the production capacity and the product ranges. Now World can supply power press capacity from 6.3ton to 2500ton, C fame and H frame crank press, tie-rod and mono block type eccentric gear press, hydraulic shearing machine and bending machine (press brake), fiber laser cutting machine and the automatic accessories such as decoiler, straightening machine and roller NC feeder.
