Power press machine supplier by pressmachine-world.com? Yingxin World Press Machine Company has exporting center in Shanghai with professional team to follow up logistic and document process, which also saves a lot of time in middle process. More than 65 years experiences focusing on producing power press machines. Read extra information at bending press machine. We can provide installation service for all the sold out machines at customer factory. Small machines can be shipped assembled and some big machines must be shipped disassembled. That is why we provide installation service to our customer.
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.
Aluminum and high-strength steels, for example, place special demands on the individual processing steps. One factor that has a major influence on the quality of the end product is the straightening of the respective metal. In a straightening machne consisting of several stagered straighngos,the coilcrvatre o the starting matril is elmnated. In adition, any edge or centre waves in the strip material can be compensated for, using suitable machines. The aim here is to achieve the lowest possible and most homogeneus resiu sres state in order to maintain te flatness of the material during subsequent cutting processes. n lentr mesur fo th eciecy of a straighten roessis te dere of platification of the respective metal, which describes the proportio o he material os-section that is plastically deforme uring straightening. With the same yield strength and material hickness, aluminum requires significantly greater degrees of deformation than steel to achieve comparable plastification.
