Metal press machine manufacturer and supplier 2023: The realm of manufacturing is vast, and within it, mechanical press machines and hydraulic press machines have staked their claim, each demonstrating its unique value across a broad range of applications. Mechanical press machines are the stalwarts of operations demanding high speed and precision. These machines are characterized by their incredible rate of production, making them indispensable in industries that rely heavily on volume and consistency. For instance, the automotive industry extensively uses mechanical presses in the fabrication process.

What is a metal stamping press machine? The technical definition of metal stamping is that it is a cold forming process that uses high force and/or speed to permanently replace the shape of a piece of metal. In the case of sheet metal stamping, the workpiece is sheet metal. Anyway, metal stamping machines can also be used for wire and other types of metal. Simply put, the machine uses a die to make the shape of the metal. Brass, steel, and aluminum are some of the most generally used metals. The stamping process may look different depending on what is being produced, but the shapes are generally made from sheet metal, placed on a stamping die and put into a press.
There are, however, notable benefits to using a hydraulic press machine. The ability to apply a tremendous amount of controlled force is the most important. Because of this, industries where force and control are prioritized over speed should always use hydraulic presses. In addition to being able to handle a wider array of materials and operations, hydraulic presses also offer greater versatility. Because of its fluid-based functioning, the hydraulic press machine is also typically quieter and safer to use than its mechanical counterpart.
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.

Structures of hydraulic press brake machinesThe hydraulic press brake is an important equipment for the bending and forming of wokieces in the shet meta instry It functionis to press the telplate into parts of various shapes according to the process requirements. The frame is mainly composed of lf an right columns, wokbenches, and beams. Teleft and right oil cylinders are ied on th colms. The slider is connected with the pistons of th oil cylinders. The lower mold is tixed on the worktable. The upper punches are installed athe lower end of the slider. The hydraulic system provides power, and the electrical system gives instructions. Under the action of the oil cylinder, the slider drives the upper mold downwards and closes the lower mold to realize the folding of the sheet. The lett andrght columns, the workbench and the sliding block hereinafter refere to as h three major parts)are the key parts of the bending machne. The tl weighto te three major parts accounts for 70% to 80% of the total weight of a bending machine. Its strength and rigidit directy determine the operating accuracy, service life of the machine tool, and the ccuracy of the workpiece.
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.
In particular, the resilience stress stat,the flatness and the cuting quality are very important quality characteristics that must be considered for the materials n the staightening and feeding technology. Remarkably, these criteria play a decisive role i te qualit of the final product even befre te final molding. In production, for reasons of cost and time, the aim is to achieve an ever-higher degree of automation, which can only be achieved if the semi-finished products have perect latness, a lowlevel o residual stress. lf these requiremets are not met, this can have a negative effect on handling and further processing or even make it impossible.
