Bending press machine provider in China? World has been committed to the development and production of power press machines since it was established in 1953. More than 100 experienced engineers are working in the three R&D centers, one in Shanghai, one in factory and another one in Ningbo. See even more details at power press machine. Working together for customer success. Since the foundation of the Yinxin world press machine company, one of the foundation principle has been to work closely with our customers. This provides the opportunity to continually assess and improve the levels of service we offer and to create the most innovative products available.
The repeatability of the slider of the CNC bending machine is 0.0004 inches, and the precise angle of forming must use suchprecision and a good mold. Therepeatilty of the lder o the hand-controlled bending machine is +0.002 inches, and the deviationo t2-3 is geneally generated under the condition of using a sutable mold. In addition, the Cc bending machine is ready for rapid mold assembly. When many small batches of parts need to be bent, this is an indisputable reason for consideration.
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.
When free bending is used, the bending radius is 0.156 times the opening distance of the die. During the free bending process, the opening distance of te die shoul b 8 tms te thickness of the metal material. For example, when using 1/2 inch (0.0127 m) open distance to form 16 gage mild see, the bendig adis o the par is about0.078 inches. I h bndig radius is almost as small as the material thickness, a bottomed die must be formed. However, the pressure required for forming a bottomed die is about 4 times greater than that of free bendingIf the bendig radius is less than the thickness of the material, a punch wit afrontend filet radus smaller than the thickess of the material must be used, and the imprint bending methoc must be used. In this way, 10 times the pressure of free bending is required.
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.
