ADH CNC Hydraulic Press Brake 110T/3200 4+1 axis

General Features

·        New EU streamlined design

·        The whole frame of the press brake adopt integrated welding, and by tempering to eliminate the internal stress

·        The press brake frame adopt shot blast to remove rust and sprayed with anti-rust treatment

·        The frame is formed by the imported CNC three-dimensional machining center in one process, which ensures the parallelism and verticality of each mounting surface.

·        The controller can control the Y1 and Y2 axes (Y1 controls the left cylinder and Y2 controls the right cylinder) to ensure the synchronous movement of the ram

·        Quiet speed waiting and fast down, (about 25 decibels), low noise during pressing and return (the pressure in the hydraulic system is the closed loop control of the servo main motor)

·        The main oil pump does not apply work under the drive of the servo main motor, and the energy consumption is 60% lower than that of the general CNC press brake machine

·        The machine oil temperature is stable, which extending the service life of various components of the hydraulic system

Machine Tool Features

1. Structural features of the machine tool

This machine is electro-hydraulic synchronous CNC bending machine with Y1, Y2, X, R, V ( 4 + 1) axis . The frame is composed of oil tank, support, worktable, left and right wall plates and slider to ensure the structural strength of the frame. After welding, it is processed by stress relief and processed on a large floor milling-boring machine, especially the slider adopts vertical processing technology (because the working state of the slider is vertical) to ensure the straightness of the mounting surface of the top punch in the working state.

2. Host structure

·        Adopt all-steel welding frame, assembled worktable structure, high precision and good rigidity.

·        The welding seam of the equipment has no welding defects such as undercuts, blowholes, cracks, etc., the outer surface of the welding seam is polished and smooth, and there is no flying spatter. The overall surface of the equipment is flat and bright without bumps.

·        The main components adopt UG \ ANSYS \ CAD three-dimensional finite element analysis and optimized design; Ensure that the machine design is beautiful , reliable structure and stable  work

·        The structural parts of the important welding part are subjected to stress relief to improve the stability of the machine tool and ensure that the frame is not deformed.

·        Large floor milling-boring machine is processed at one time to ensure the overall accuracy of the workpiece

·        The throat is equipped with a "C" shaped plate mechanism to directly detect the distance between the upper and lower molds to ensure the accuracy of the parts;

·        Due to the feedback of the grating ruler and the control of the synchronous valve, it has a strong anti-eccentric load capacity

·        Two grating ruler are equipped Y1 and Y2 axes side, it mainly to detect the distance between the slider and the worktable. The grating ruler is connected to the worktable. The deformation of the column will not affect the positioning. After the position data will feedback to the CNC system, you can measure the output servo valve control signal

·        The X axis is composed of servo motor, liner guide and ball screw, with high accuracy and repeated positioning accuracy

·        The V axis is the convexity of the Vera control table

3. Slider structure

·        Upward moving bending design, low noise, stable working condition

·        The slide rail surface is installed with a self-lubricating guide plate made of wear-resistant material

·        The slider is rigidly connected to the oil cylinder, which can better ensure the synchronization accuracy requirements of the slider in the fast forward, working and fast return states

·        The bottom dead center has a dwell time and is programmable to ensure the accuracy of different workpieces

·        With the function of slow return control, the operator can better control the workpiece

·        Universal top punch mounting surface can meet the clamping requirements of the mold

4. Hydraulic system

·        Using the most advanced all-electro hydraulic servo synchronous control system

·        Complete sets of hydraulic system imported from HAWE Germany

·        Using imported liner grating ruler, high precision guidance system, position measurement system and hydraulic equalization function, can meet the needs of full length or eccentric processing

·        The inner seal of oil cylinder is an international famous brand with strong sealing performance and long service life

·        Hydraulic system has overload overflow safety protection

·        Oil pump high pressure filter blocking alarm

·        Clear and visual display of oil level height

·        The machine tool can work continuously under rated load, the hydraulic system ensures no leakage, and the processing is stable, with high precision

·        The oil cylinder is finished by forging through rough processing, tempering, finishing, inner wall grinding, inner wall floating boring and rolling, so that the inner wall of the oil cylinder is not only wear-resistant, but also has high Cylindricity Precision. The piston rod is finished by forging through rough processing, tempering, quenching, finishing, hard chromium plating, external grinding and other processes.

5. Electrical system

·        The electrical components are imported from abroad or joint venture products, which are in line with international standards, safe and reliable, with long service life and strong anti-interference ability

·        Movable button (including foot switch), easy to operate, with emergency stop function

·        Necessary limit protection measures shall be taken for the working system. In case of any abnormality, it shall be able to detect through the system and give an alarm immediately

·        The layout of the electrical cabinet is reasonable, the main circuit and the control circuit are considered separately, and enough space should be left for easy maintenance

·        The terminal block has a reasonable structure, the terminal has a protective nose, the wire number is clear, and it is oil-proof and durable

·        There are sealing measures at the entrance and exit of the electrical circuit, the direction of the circuit is clear, and the marking is clear
