Five evaluation standards for electro-hydraulic synchronous CNC metal press brake bending machines
Primapress brand Professional manufacturer of CNC metal press brake bending machines, CNC shearing machines, and CNC rolling machines
The CNC bending machine is used to bend the metal plate in cold state into workpieces of various geometric cross-section shapes by using the equipped mold (general or special mold). The bending machine generally uses the special CNC system for the bending machine. The coordinate axis of the bending machine has developed from a single axis to 12 axes. The CNC system can automatically realize the control of the sliding block running depth, the left and right tilt adjustment of the sliding block, the front and rear adjustment of the rear stopper, the left and right adjustment Pressure tonnage adjustment and slider approaching working speed adjustment, etc. It can make the bending machine conveniently perform actions such as sliding block downward, jogging, continuous, pressure maintaining, return, and midway stopping, and complete multi bend bending at the same or different angles with one feeding.
In practical use, the evaluation criteria for electro-hydraulic synchronous CNC metal press brake bending machines are as follows:
- The speed and softness of the Y-axis (bending angle) direction, the faster the speed, the better. Whether it will exceed 200/s, preferably reaching 270/s, and the slow speed should be below 10mm. The transition between fast and slow speed should be gentle.
- Is the speed of the rear stopper (X-axis bending size) gentle from slow to high speed and back to slow speed (0/s-500/s-0/s)? The full travel time should be shorter, and the shorter the better.
- Noise, whether it is the Y-axis (bending angle) or the rear bumper (X-axis bending size), will the sound of the machine be too loud.
- For example, fold the C-shaped steel at the C-port and use a vernier caliper to measure the spacing between the C-ports in sections to see if they are even and what is the tolerance.
- Appearance: Whether the paint is flat and even.
The structural characteristics of the Primapress brand electro-hydraulic synchronous CNC bending machine are welded to the entire steel plate, and stress is eliminated by vibration after tempering, with good stability; Machine shot blasting and rust removal, with rust prevention treatment sprayed; The frame is clamped and formed in one operation by an imported CNC three-dimensional machining center, ensuring the parallelism and verticality of each installation surface.
