Top rated power press machine manufacturer and supplier today? 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. See extra info at hydraulic press machine.
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.
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. 80% parts are produced in same factory for better quality control and future service. World has completed high-quality production equipment, including the iron casting line, plasma laser cutting machines, welding robots, gear hobbing machines, gear grinding machines, Pama boring and milling centers, CNC lathes, anneal treating furnaces, sand blasting machines, three-coordinate measuring instruments and ultrasonic flaw detectors.
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.
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.
