CNC bending machine working principle and use method
The numerical control bending machine mold for bending the thin plate comprises a bracket, a worktable and a clamping plate. When used, the coil is energized by the wire, and after the power is applied, the clamping force is generated on the pressing plate, thereby realizing the clamping of the thin plate between the pressing plate and the base. hold. Thanks to the electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece with the side wall can be processed, and the operation is also very simple. According to the ordinary hydraulic CNC bending machine mold processing Q235 sheet for a brief introduction: 1. First turn on the power, turn on the switch on the control panel, and then start the oil pump, so you hear the sound of the oil pump. (The machine does not work at this time) 2. Stroke adjustment, the use must pay attention to adjust the stroke, must be tested before bending. It must have a plate thickness gap when the upper die goes down to the bottom. Otherwise it will cause damage to the mold machine. The adjustment of the stroke is also electrically adjusted quickly. 3. For the selection of the bending slot, it is generally necessary to select the slot with a width of 8 times the thickness of the plate. For bending 4mm sheets, you need to choose a notch of about 32. 4. The back gauge adjustment generally has electric quick adjustment and manual fine adjustment, the same method as the shearing machine. 5. Press the foot switch to start bending. The CNC bending machine mold is different from the shearing machine. It can be released at any time. Release the foot and stop it. Plastic CNC bending machine mould, plastic folding machine, plastic plate CNC bending machine mould, plastic sheet bending plastic sheet direct bending, no need to splicing, no need to slot, no need for welding rod, its angle of appearance is not beautiful Water leakage, which transforms manual welding into fully automatic machine operation, improves quality, improves labor efficiency, reduces labor costs, and greatly shortens the product production cycle. The automatic plastic folding machine is an electrical integrated automatic mechanical equipment. Developed according to the principle of heating, softening and fusion welding of plastic sheets, it is suitable for the folding angle of all thermoplastic materials. The speed is fast, the angled surface treatment is beautiful and the strength is high. The hydraulic shearing machine is divided into pendulum type and gate type. The pendulum type activated carbon is a circular arc motion, and the arc blade is quite difficult to manufacture. Generally, the blade is used to compensate the horn, so the resulting gap is not accurate. The cut sheet is not very ideal. Because it is a curved movement, 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 more severe. The domestic representatives of the board machine are Tianshui Machine Tool Plant and the punching and shearing machine tool factory. The gate hydraulic shearing machine has overcome all the above problems. However, there are not many domestic manufacturers that can do the gate shearing machine. Compared with the shearing machine, the technical content of the CNC bending machine mold is slightly higher. At present, the domestic common G-shaped and F-shaped, F-shaped should be the domestic traditional products, the use of built-in adjustable machinery The positioning of the block is very weak due to the built-in anti-offset capability. Therefore, Huangshi has a balance valve in the mold of the early CNC bending machine, but it is also complicated by hydraulic pressure, which brings serious damage to the later maintenance and stability. Problem. The latter type is the G type after the F-model is improved. It uses the outer slide mechanical positioning, which is simpler than the F-type. It is more convenient to debug, even if the angle between the two sides is different. Non-professionals add spacers to solve the problem. There is also a type of H-type CNC bending machine mold, its structure is very different from the previous two, it is a lever type structure, generally used for large tonnage CNC bending machine mold, through the principle of lever amplification, the force is amplified. At the same time, it adopts the position control of electric/liquid/number combination, which makes it cost-effective on the same bending machine die of the same tonnage. However, there are not many manufacturers that can produce such models in China, and CNC hydraulic sheet material CNC bending The main features of the machine mold bed: WC67K CNC bending machine mold, using steel plate welding structure, vibration aging to eliminate stress, the machine tool has good rigidity and stability, the whole frame is rigid, stable, safe, reliable and easy to operate. Through the coordinated control of the numerical control system and hydraulic system of the CNC bending machine, the ideal bending effect is achieved. The main part of the machine tool and structure description: 1. Slider part: hydraulic drive, the slider part is composed of slider, oil cylinder and mechanical stop fine adjustment structure. The left and right cylinders are fixed on the frame, and the piston (rod) is driven by the hydraulic pressure to move the slider up and down, and the mechanical stop is controlled by the numerical control system to adjust the value. 2. Workbench part: It is operated by the button box, so that the motor drives the material rack to move back and forth, and the distance controlled by the numerical control system is controlled. The minimum reading is 0.01 mm (the travel position limit is available in the front and rear positions) 3. Synchronous system: The machine consists of a mechanical synchronizing mechanism consisting of a torsion shaft, a swing arm and a joint bearing. The structure is simple, the performance is stable and reliable, and the synchronization precision is high. The mechanical stop is regulated by the motor and the numerical control system controls the value. 4. Blocking mechanism: The gear is driven by motor, and the two screw rods move synchronously through the chain operation. The numerical control system controls the size of the material. The combination of laser processing system and computer numerical control technology can form an efficient and automatic processing equipment, opening up broad prospects for high-quality, high-efficiency and low-cost processing and production. The laser engraving machine is a high-tech integrated new laser peripheral processing equipment that combines laser technology and computer technology. The laser engraving machine adopts high-performance laser and numerical control technology to realize three-dimensional dynamic precision laser engraving in crystal and glass through self-developed optical system, control system and computer software, which solves the problem of slow engraving, unstable system operation and lost laser Point, the image and word processing software is incomplete, using computer interface control card, laser explosion point uneven, automatic control device is not perfect, equipment cost is low and so on. The overall efficiency, accuracy, maintainability, versatility and safety of the system are improved. It is inevitable that crystal glass engraving works become richer in color. The inner part of the crystal glass crafts has a strong reflection and refraction effect on the light, and the optical part of the blank part has good permeability to the light, and the micro control circuit controls the several according to the principle of the three primary color palettes. The color of the lights, mixed in the "inside carving" image, changes a variety of beautiful colors, so that the original white internal carving image presents a colorful, dazzling effect. The working principle of the three-point CNC bending machine mold, the corner of the entrance of the die and the surface of the core are composed of three points A, B and C. The bending angle α of the workpiece is determined by these three points, wherein the C point is the most stressed, and it is returned with the material. There is a direct relationship between the correct or small amount of the angle α. As shown in the figure, as long as the size of the "core" of the core is changed, different bending angles can be obtained. The angle control is to mount a dial on the support, and then install the upper arm on the core. The pointer is displayed on the dial, which is characterized by simple and intuitive angle control operation. It can bend the busbars of different angles without special molds. The bending is mandatory bending and can improve the bending precision. The difference between the bending shearing machine of the movable die clamp of the device, the numerical control bending machine die and the traditional numerical control bending machine die is that a movable die clamping clamp is arranged on the sliding upper beam, and is simultaneously mounted on the movable die clamping clamp. Bending die and shearing knife or two kinds of bending die at the same time, the bending die and the shearing knife are mounted on the movable die clamp; two kinds of bending are mounted on the movable die clamp The mold is called the CNC bending machine mold. When the bending shearing machine is used, the movable cutter die clamp can be rotated to the corresponding position to be converted into a bending function or a shearing plate function; when the CNC bending machine mold is used, the movable cutter die clamp can be rotated to the corresponding position to be transformed. A thin plate bending mode bending function or a thick plate bending mode bending function. The operation of the bending shearing machine is as convenient as a single CNC bending machine mold or a single shearing machine, but the manufacturing material is greatly reduced; the CNC bending machine mold is quick to change the mold and is very convenient to use.
