When the cold bending machine presses the running command, EPS Block Molding Machine the cold bending forming unit main motor first drives the cold bending roller to rotate at a certain speed, this rotation speed mainly by the cold forming of the shelf forming process, the mechanism speed ratio, the cold rolling roll structure size, the hydraulic Shear shear and the unit set the operating speed and other parameters of the decision.
When the shape of the cold-formed components through the transmission track hole position detection photoelectric switch position, send off the power signal to the hole number counter to count, when the hole number reaches the set value when the position detection signal, the rotary encoder to a certain Distance detection and to provide a certain number of pulses to the PLC, PLC to detect the number of pulses, EPS Block Molding Machine the main motor to send a deceleration, stop the command, while the main motor to the hydraulic sequence control valve after the cut off control command to drive the hydraulic shear to cut off the operation.
According to the above principles, the design of the cold-bending unit can achieve precision: hole error does not exceed ± 0.3mm, hole cumulative error of more than ± 0.5mm, single product length control accuracy is generally controlled about 0.5mm, EPS Block Molding Machine to a certain extent to meet the shelf Design Accuracy of Steel Structure Assembly.
The Dynamic Matching Problem between the System and the Load in the Servo System of the Pre - punching Unit with the Load Run.
Cold bending machine rolling stability problems, the production of materials often encountered in the raceway in the left and right side of the problem, in fact, EPS Block Molding Machine a single group of rollers by the asymmetry, the left side of the force, the material to the right side of the pendulum; , EPS Block Molding Machine The material to the left side of the pendulum. The solution is:
The neutral layer of the deformation area is accurate, the material used in the deformation area is accurate and the roller processing symmetry is good.
No deformation of the region as far as possible without pressure (such as the bottom of the slide), the assembly of the upper and lower rollers when the regional gap to maintain consistency.
Material bite before, should be based on the previous road rolling state, EPS Block Molding Machine set the guide ramp, before the steady pressure, the material in the roll smooth smooth.
Cold bending machine production in the bending of the problem, mainly caused by uneven force, about force imbalance, left and right bending, up and down the force imbalance, resulting in distortion.
