WE67K Electro Hydraulic Bending Machines for Sale

Electric Hydraulic Press Brake Product Shape Structure

1. All steel structure design, production, beautiful appearance and reliable structure.

2. Using UG (finite element) analysis method, computer-aided optimization design.

3.the overall steel plate welded structure, vibration aging to eliminate internal stress, so that the fuselage has good strength, stiffness and stability.

4.The left and right vertical columns are welded with a bottom plate to fix two oil cylinders. The left and right cylinders are placed at both ends of the slider, and the slider and the cylinder are connected by a piston rod, and the hydraulic system drives the up and down movement. The table is supported by a circular pad and an adjustment pad and is screwed to the column. The lower part of the column is equipped with left and right support angle irons to increase the bottom contact area to prevent tilting during transportation.

5. The overall frame is rust-removed by sand blasting and sprayed with anti-rust paint.

Electric Hydraulic Press Brake Structural Features

The frame is composed of the fuel tank, support, workbench, left and right wall panels, and sliders as an integral structure, which ensures the structural strength of the frame. After welding, it is stress-relieved and processed on a large floor boring and milling machine. Especially for the slider, the vertical processing technology is adopted (because the working state of the slider is vertical) so as to ensure the straightness of the upper die mounting surface of the slider in the working state.

This machine has high labor productivity and high working precision for bending metal sheets. It adopts upper and lower molds of different shapes, which can be bent into various shapes of workpieces. The sheet metal can be bent and formed once with one stroke of the slider. A workpiece with a more complex shape can be obtained after multiple bendings, and it can also be used for punching when equipped with corresponding equipment.

Electric Hydraulic Press Brake Hydraulic system

1. Adopt the most advanced fully closed-loop electro-hydraulic servo synchronous control system;

2. The complete set of hydraulic system is imported from German ARGO company;

3. Imported linear grating ruler, high-precision guiding system, position measuring system and hydraulic equalization function are selected to meet the processing needs of full length or eccentricity;

4. The seal in the oil cylinder is an international famous brand, with strong sealing performance and long service life;

5. The hydraulic system has overload overflow safety protection;

6. Oil pump high-pressure oil filter blockage alarm;

7. The oil level is clearly and intuitively displayed;

8. The press brake tool can work continuously under the rated load, and the hydraulic system ensures no leakage and continuous and stable processing with high precision;

9. The oil cylinder is completed by forgings through rough machining, quenching and 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 accuracy. The piston rod is finished by rough machining, quenching and tempering, quenching, finishing, hard chrome plating, cylindrical grinding and other processes from the forging.

Electric Hydraulic Press Brake Electrical System

1. The electrical components are imported or joint venture products, in line with international standards, safe and reliable, with long life and strong anti-interference ability;

2. Movable button station (including foot switch), easy to operate, with emergency stop function;

3. The working system must have necessary limit protection measures. Once an abnormality occurs, it should be able to detect through the system and give an alarm immediately;

4. 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;

5. The structure of the terminal block is reasonable, the terminal block is equipped with a protective nose, the wire number is clear, and it is oil-proof and durable;

6. There are sealing measures at the entrance and exit of the electrical circuit, the direction of the circuit is clear, and the label is clear;

7. Motor overload and short circuit protection adopts automatic air switch;

8. Short circuit protection of the control circuit;

9. All "emergency stop" buttons are interlocked, press any one, the bending machine tool will stop.

Electric Hydraulic Press Brake Backguage

1. The adjustment of the back gauge is driven by a servo motor.

2. The rear gauge screw is positioned by a precision ball screw and supported by a linear guide.

3. H-type synchronous belt synchronous wheel transmission, high transmission precision, low noise.

4. Adopt up and down adjustable finger block, and can be fine-tuned front and back.

Electric Hydraulic Press Brake Mold

1. The upper mold adopts heavy-duty clamping T-slot.

2. The upper and lower molds adopt segmented short molds, and the length required for splicing has high precision and good interchangeability, and is easy to disassemble. The connecting part is equipped with a compensation mechanism to compensate the deflection of the worktable and the slider when bending the sheet to ensure high working accuracy.

3. The lower mold is processed into different "V"-shaped grooves for easy selection by the operator, and it is equipped with a lower mold turning mechanism. Just put the lifting chain on the slider lug and the lower mold lug, loosen the top mold to lift The slider can rotate the lower die to select the required "V" groove position surface.
