Power press machine provider in China? Hydraulic transmission is adopted, and the slider part is composed o slide, an oil cylinder and a fine-tuning structure of a mechaicl stoper. Te left and right oil cylinders are fixed on the frame, the piston (rod) drives the slider to move up and down through hydraulic pressure, and the mechanical stop is controlled by the numerical control system to adjust the value; Workbench part: controlled by the button box, the motor drives the stopper to move back and forth, and the moving distance is controlled by the numerical control system. The minimun reading is 0.01 mm (the front and rear positions have travel switch limits). Find even more information on world press machine.
Side length of bending part: Assumin tht it is bent 90° longa 5 10-oot 1-gauge low-carbon steel plate, the bending machin mu apla ditonal 5 tos of pressr to lifthe sel plae u, ad the operator must be prepared for the 280-pound straight edge drop. Several strong workers or even a crane may be required to manufacture this part. Operators of bending machnes oteneed to bend long-side parts without realizing how strenuous their work is.
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. Fast delivery standard machines stock for sale: Standard C frame single crank press and eccentric press are always some units stocking for sale. 2 weeks to 30 days lead time for customized order. Big press line such as car body parts stamping line could be ready for shipment within 4 months after order.
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.
