Shear bending machine working principle
Shears roughly divided into two types of mechanical and hydraulic.
Mechanical principle of the root of the principle of mechanical punch or less the same, but the dry sound is too large, no, adjusting the gap too much trouble ..... has gradually be phased out. shearing machine
Is divided into tilting hydraulic shears and gate type. Swing Beam Shear campaign because it is circular, and the circular blade production would be quite difficult, is generally done with a blade after the Sizing Block compensation, so the resulting gap and inaccurate, cut out the sheet metal is not very satisfactory. because it is curved movement rectangular blade can not be made, but should make an acute angle, so the blade edge of the picture is not ideal, more powerful blade injury. do Swing Beam Shear representatives Tianshui domestic machine tool plant with Shanghai Machine Tool Plant PUNCHING. brake hydraulic shears to overcome all of the above problems. However, domestic manufacturers can gate-type shears not many, the main representative Yellowstoneshearing machine LVD Belgium for the introduction of the company's shears.
Compared with the shears, press brake technology content to slightly higher. Speaking to people in the bending machine will certainly think of a small Japanese domestic AMAD ~ Yellowstone. Is said to have also had mechanical bending machine, but I can only blame born too late, not seen. I know only hydraulic, so I said in this type of hydraulic press brake, the current domestic common with the G-shaped F-shaped, press brakeF-shaped should be the traditional domestic products, its adoption is a built-in adjustable mechanical block positioning, because it is built-in capacity to carry its anti-migraine quite weak, so it is Yellowstone in the early bending machine has a balance valve, but also as a result of fluid pressure system over complicated, to the maintenance shearing machineand stability of the latter very serious problem.shearing machine The latter is in the F-type models to improve after the G-type, and its use of outside skateboards mechanical positioning, compared with F-its structure is more simple, more convenient for debugging, even in the perspective of the difference between both sides of the circumstances can also be initiated by non-professional people to lift the issue of taxi gasket.
There is now an H-bending machine, its structure than the two are very different from before, its leveraged structure, generally used...
