Hydraulic bending machine manufacturer in China

Metal stamping press machine manufacturer and supplier right now: Mechanical presses are also extensively used in the metalworking industry, particularly in operations like piercing, blanking, and forming. Whether it’s creating intricate components for electronics or fashioning parts for heavy machinery, mechanical press machines are at the heart of these high-speed, precision-driven processes. On the other end of the spectrum, the hydraulic press machine is the hero in situations that call for raw power and control rather than speed and precision. Unlike their mechanical counterparts, hydraulic presses are more about forceful impact and controlled operations. They have become the favored machines in industries where the tasks involve heavy-duty shaping, molding, or straightening. Find extra info on brake press machine.

How does a stamping press machine work? The general operation of a metal stamping is easy: put the material into a machine that can immediately apply many tons of force and use them to press the metal object into the shape you want. Sheet metal stamping machines can generally perform many different processes. This is similar to flattening because it makes the workpiece thinner, but this process is generally used for wire rather than sheet metal. Profile-forged wire makes one end narrower so it can fit more simply into an opening.

When time, accuracy, and productivity are of the essence, a mechanical press machine is usually what’s used. Because of its speed and accuracy, the mechanical press is well-suited for industrial manufacturing. In addition, mechanical presses often have lower maintenance expenses because to the reduced number of moving parts. While a hydraulic press excels in tasks that call for tremendous force and control, a mechanical press excels in those that require rapid speeds and precise movements. So, whether a mechanical press or a hydraulic press is the better option depends on the task at hand.

Even if there are shelves full of molds, don’t assume that these molds are suitable for the newly purchased machine. The wear of each mold must be checked by measuring the length from the front end of the punch to the shoulder and the length between the shoulder of the female mold. For conventional ols, the deviation per foot should be about t0.001 inches, and the total length deviation should not be greater than t0.005 inches. As for the precision grinding mld, the accuracy per foot should be ±0.0004 inches, and the total accuracy should not be greater than ±0.002 inches. It is best to use fine grinding molds for CNC bending machines, and conventional molds for manual bending machines.

Main features: Adopt all-steel welded structure, with sufficient strength and rigidity; Hydraulic drive, the oil cylinders at both ends of the machine tool are placed on the sliding block to directly drive the sliding work; The slider synchronization mechanism adopts torsion shaft for forced synchronization; Using mechanical block structure, stable and reliable; The stroke of the slider can be adjusted quickly by motor, fine-tuned manually, and the counter is displayed; Oblique wedge-type deflection compensation mechanism to ensure higher bending accuracy.

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.
