Numerical control bending machine working principle and use method

The CNC bending machine mold includes a bracket, a work table and a clamping plate. When used, the wire is electrified on the coil, and the power produces gravity on the pressing plate, so as to realize the clamping of the thin plate between the pressing plate and the base. Because of the use of electromagnetic force clamping, the pressing plate can be made into a variety of workpiece requirements, and can be processed on the side wall of the workpiece, the operation is also very simple. According to the ordinary hydraulic numerical control bending machine mold processing Q235 sheet material to do a brief introduction:

1. First, connect the power supply, open the switch on the control panel, and then start the oil pump, so that you can hear the sound of the oil pump rotation (the machine does not act at this time).

Preparation before startup

1. The guide rail, rear stopper and other moving parts with centralized oil supply should be refueled regularly;

2. Check mold cleaning and damage degree, and deal with abnormality in time;

3. Check the parallelism of rear stopper and the tension of drive belt.

Boot Steps Tutorial

1. Operate the machine correctly according to the operation steps;

2. In case of any abnormal condition during machine operation, stop checking immediately and troubleshoot with reference to the relevant troubleshooting methods in the Training Manual;

3. If the machine stops due to alarm during operation, it should be treated differently and not run blindly to avoid damage to the machine;

4. For the newly executed program, the first piece of work must be checked according to the drawing to avoid batch error;

5. Stop the machine in time to check if there is any abnormality in the mold in the bending process;

6. Check regularly whether the actual position of X axis is consistent with the detected value, and adjust it in time if there is any deviation.

2, travel adjustment, use must pay attention to adjust the travel, must be tested before bending. There must be a plate thickness clearance when the upper die moves down to the bottom. Otherwise, it will cause damage to the mold machine. The adjustment of the stroke is also a quick electric adjustment.

3, bending groove selection, generally choose the plate thickness of 8 times the width of the groove. Such as bending 4mm sheet material, need to choose about 32 notch.

4, the rear stopper adjustment is generally electric quick adjustment and manual fine tuning, the method is the same as the plate shearing machine.

5, step down the foot switch to start bending, CNC bending machine mold and shearing machine is different, can be released at any time, loosen the foot will stop, continue to step down. Plastic CNC bending machine tooling, plastic folding machine, plastic board CNC bending machine mold, plastic plate bending plastic plate bending directly, without joining together, without slot, don't need a electrode, the Angle of the appearance it hold water, it will be hand soldered into a fully automatic machine operation, improve the quality, improve the work efficiency, reduce the labor cost, shorten the production cycle of products. Automatic plastic corner folding machine is an electrical integration of automatic mechanical equipment.

It is developed according to the principle of heating and melting of plastic plate, which is suitable for bending Angle of all thermoplastic materials. High speed, beautiful surface and high strength. Hydraulic shearing machine is divided into pendulum type and gate type. The pendulum activated carbon because it is circular arc movement, and the arc blade production is very difficult, generally with the blade after the cushion iron compensation, so the gap is not accurate, cut out of the sheet is not very ideal. Because it is an arc motion, the blade can not be made into a rectangle, but should be made into an acute Angle, so the force of the blade is not ideal, and the blade damage is also severe. Do pendulum plate shearing machine domestic representative for Tianshui machine tool factory and punch shearing machine tool factory. Sluice type hydraulic shears to overcome all the above problems. But at present domestic manufacturers can do the brake type plate shearing machine is not much. Relative to the shearing machine, numerical control bending machine mold technology content is slightly higher.

At present domestic common G shape and F, F shape should be domestic traditional product, its use is built-in adjustable mechanical stop positioning, because it is built-in the partial load resistance is weak, so have the Yellowstone in the early days of CNC bending machine mold has a balance valve, but also because of the hydraulic, too multifarious, brings to the late maintenance and stability is very serious problem. The latter is in the F-type model after the improvement of the G type, the use of external slide mechanical positioning, compared with the F-type it is more simple, debugging is more convenient, even in the case of the difference in the Angle of both sides can also be removed by non-professionals with gaskets.

Now there is also a H-type CNC bending machine mold, its structure is very different from the two before, it is a lever structure, generally used for large tonnage CNC bending machine mold, through the lever amplification principle, the force amplification. At the same time, it uses the position control of electric, liquid, number combination, so that it is especially cost-effective in the same tonnage CNC bending machine mold. But domestic manufacturer of this kind of model is not much, numerical control hydraulic sheet metal numerical control bending machine mould bed main features: WC67K CNC bending machine tooling, USES the steel plate welded structure, vibration aging eliminate stress, machine tool has very good rigidity and stability, and the whole frame rigidity, stable, safe and reliable, easy to operate, through the CNC bending machine mould numerical control system and hydraulic system of the coordinated control, to achieve the ideal effect of bending.

Main parts and structure of the machine:

1, slider part: hydraulic transmission, slider part is composed of slider, cylinder and mechanical stopper fine tuning structure. The left and right oil cylinders are fixed on the frame, and the piston (rod) drives the slider to move up and down through hydraulic pressure. The mechanical block is controlled and adjusted by the numerical control system.

2, the table part: by the button box control, so that the motor drive the block frame move before and after, and controlled by the numerical control system moving distance, the minimum reading is 0.01 mm (before and after the position have travel switch limit).

3, synchronization system: the machine is composed of torsional shaft, swing arm, joint bearing and other mechanical synchronization mechanism, simple structure, stable and reliable performance, high synchronization accuracy. The mechanical stopper is adjusted by the motor, and the numerical control system controls the value.

4, the retaining mechanism: the retaining material adopts the motor drive, through the chain operation to drive the two screw moving synchronously, the numerical control system to control the size of the retaining material. Laser machining system and computer numerical control technology can be combined to form efficient automatic processing equipment, which opens up a broad prospect for high quality, high efficiency and low cost processing and production. The laser inner engraving machine is a new type of laser peripheral processing equipment which combines laser technology with computer technology. With high-performance laser laser engraving machine and CNC technology, through independent development of the optical system, control system and computer software, in the crystal, glass, realize the dynamic precision of 3 d laser engraving, carving slow and system is solved, the laser spot, the image and word processing software function is not complete, the use of computer interface control CARDS, laser flash uneven, automatic control device is not perfect, low equipment cost performance problems. It improves the efficiency, precision, maintainability, versatility and security of the system. It is inevitable that work of carving inside crystal glass becomes richer on color. Using crystal glass handicraft carving in part to light has strong reflection, refraction, and the blank part of the light has better performance of optical principle, fully by the micro control circuit according to the principle of three base color palette, each control several kinds of color the lamp, mixed color on the "eagle" icon, change a variety of gorgeous color, so that the tableland of this white inside carving images present a colorful, dazzling effect.

Numerical control bending machine working principle

3 point CNC bending machine working principle of the mould, die entrance Angle of garden and the surface of the core of A, B, C three points, be determined by the three points bending workpiece Angle alpha, largest stress of C point, it and the material springback amount of alpha Angle correctly or not has A direct relationship, pictured above, as long as change the size of the mould core "distance" can obtain different bending Angle, Angle control is in the bearing with A dial, then turn on the mold core jacket arm drives the pointer displayed on the dial, its characteristic is Angle control operation is simple and intuitive, can bend without special die different angles of busbar, the bending is A mandatory bending, and can improve the precision of bending.

A knife mold clamp device activities bending shearing machine, CNC bending machine mold and traditional CNC bending machine mold in the sliding liang is the difference between a knife mold clamp, cutting die clamp on the activity at the same time equipped with bending modulus and shear BanDao or containing two kinds of bending die at the same time, the active die cutter holder hat bending modulus and shear BanDao said bending shearing machine; Two kinds of CNC bending die are installed on the movable cutter die holder. When the bending and shearing machine is used, the control and push the active cutter die clamp to rotate to the corresponding position, which can be changed into the bending function or the shearing function; When the CNC bending machine is used, the active cutter die clamp is pushed to rotate to the corresponding position, which can be changed into the thin-plate bending die bending function or the thick-plate bending die bending function. The operation of the bending and shearing machine is as convenient as a single numerical control bending machine mold or a single shearing machine, but the manufacturing materials are greatly reduced; Numerical control bending machine mold change fast, very convenient to use.
