Hydraulic bending machine is used to make bends in thick heavy sheets and to make intricate bends in thin materials. There are 2 types of bending machines: mechanical and hydraulic. As a huge amount of power is needed to bend the sheets or plates, the hydraulic machines are generally more ideal for every job.
Hydraulic shearing machine is out there in capacities beyond 50,000 metric tonnes.
In order to completely understand the operation of a hydraulic machine, you would like to know how it works. As benders are made of various components, keeping track of all can be tough. So, here is a basic list of some of the main components.
1. Hydraulic fluid – Hydraulic fluid is transmitted through various parts of the bending or roll forming machine. High pressure is exerted on hydraulic fluid by the pump, therefore creating highly energized fluid.
After delivering the energy, the de-energized hydraulic fluid travels back. The hydraulic fluid is generally petroleum oil with different additives.
Other than transferring the energy, the hydraulic fluid also lubricates the various components of the press brake and removes the contaminants and metal fittings. The hydraulic fluid should be capable of operative at high temperatures, as well as many hundred degrees Celsius, as it gets heated when it receives the energy in the hydraulic pump.
2. Pump – The pump truly produces the ability that energizes the hydraulic fluid and transmits it through the machine to hold out the pressing operations. If a pump has the rating of say 5,000 psi, it will maintain the flow of liquid against the hundreds of 5,000 psi or it will apply that abundant pressure. The power density of Hydraulic bending machine is 10 times that of electrical motors by volume. The pump is operated by an electrical motor or associate engine connected by gears, belts, or versatile couplings. It will be a gear pump, vane pump, axial piston pump, or radial piston pump. The pump is the “generator” facet of the full press brakes.
3. Mechanism – the ability contained in the hydraulic fluid is delivered to the mechanism that carries out the pressing operation. There are varied types of actuators, but the one employed in press brake is the hydraulic cylinder. The hydraulic cylinder is comprised of a cylinder barrel and a reciprocal piston. The huge amount of energy contained in the hydraulic fluid is transmitted to the piston to hold out the linear work of pressing the metal sheets. The stroke length of the piston can be programmed according to the density of the metal sheet and angle of the bend. The length of the piston depends on the length of the cylinder. The pressure and forces of the piston can be precisely controlled.
