The difference between torsional shaft synchronous bending machine

 and electro-hydraulic synchronous bending machine

Often people will ask the electro-hydraulic synchronous bending machine and torsional shaft synchronous bending machine which good?

LS-CMU joint potential intelligence said that the situation of each factory is different, different customers for different workpiece processing needs, bending efficiency requirements are different, there is no completely which is good which is not good, only choose suitable for their own factory to use the bending machine is the best.

LS-CMU joint potential intelligence recommendations can be referred to from the following three aspects!

First, bending speed

1. the speed of torsional shaft synchronization is slow, only to meet the general and occasional bending needs

2.the electro-hydraulic speed is about 2 times of the torsional shaft, can meet the needs of a complex bending molding

3 .small down bending machine is faster than up, because up bending machine set up the distance between the upper and lower dead point, pressure holding time, fast speed is longer than down, so that the time above will be delayed for a long time.

Second, bending synchronous effect

1. The synchronization effect of the torsional shaft is worse than that of the electro-hydraulic synchronization effect (i.e. the upper and lower positions of the left and right oil cylinders cannot be completely consistent), and the Angle error is large;Torsional shaft synchronization depends on the motor to drive the synchronous belt to rotate the synchronous shaft to press down the two cylinders for bending, so that the position of the two cylinders can not be automatically detected and adjusted

2. The electro-hydraulic servo valve synchronization synchronous depends on both sides of machine tool, the two sides each equipped with a optical ruler to automatically detect the location of the two oil cylinder go and automatic feedback to the bending machine numerical control system for automatic adjustment, and all of the bending machine system in machine tool, such as hydraulic system, CNC system form a closed-loop, makes the bending machine speed and precision

Third, bending machine rear retaining positioning accuracy and control shaft number

1. The positioning accuracy of the rear stopper of the bending machine: due to the difference of the synchronization effect, the positioning accuracy of the torsional shaft synchronization is twice or greater than that of the rear stopper of the electro-hydraulic synchronization

2, the number of control axis: the more the number of control axis of the torsional shaft bending machine, the worse the effect (up to 2+1 axis), the electro-hydraulic is not controlled by the range of the number of axes (at least 3+1 axis, that is, automatic program design can achieve high requirements, such as 4+1 axis, 5+1 axis, 6+1 axis, 7+1 axis, 8+1 axis and so on)

Understand the above three points, I believe you can know the difference between the electro-hydraulic synchronous bending machine and the torsional shaft synchronous bending machine, the torsional shaft synchronous bending machine is cheaper than the electro-hydraulic synchronous price, but the function is not much, can only meet the general bending demand: if only occasionally used, the bending speed is not high, it can choose the torsional shaft synchronous bending machine;If the use of large demand, the bending accuracy and speed has high requirements;Then choose electro-hydraulic synchronous bending machine.
