In recent years, 30% of sheet metal factories in developed countries such as Europe and the United States have begun to use folding machines to replace traditional bending machines for partial bending processing. Compared with the bending machine, the folding machine is a kind of bending equipment with many advantages, and the operation is more convenient.
The CNC press brake realizes the bending function by controlling the slider stroke and the back gauge of the bending machine. When using a CNC bending machine, as long as the part drawing of the workpiece and the bending angle of each step are input, the bending machine will be implemented one by one according to the input steps. Advanced CNC bending machine mainly adopts electro-hydraulic servo system, cooperated with a grating ruler to form full closed-loop control, with high synchronization control precision, bending precision and repositioning precision. In use, the CNC bending machine can be flexibly operated. It can not only realize the processing of ultra-long plates with dual-machine linkage but also process parts with a single machine. This not only improves the use efficiency of the bending machine but also reduces energy consumption.
Folding machine is a machine that processes the edges of products. It used to be used for large-scale production of stainless steel sheet products with simple shapes, but with the continuous update and maturity of technology, these products are now more produced with cold-formed punches. The folding machine uses a model with a bending radius to fix the steel plate on the workbench of the machine tool, and the part of the material that extends is placed on the movable workbench, which can rotate along the center of the bending radius. The movable table rises to bend the stainless steel to the required angle. When bending, due to the sliding of stainless steel on the workbench, in order to prevent material scratches, on the one hand, the surface of the workbench should be smooth, and on the other hand, a plastic film needs to be attached to the surface of the stainless steel to prevent the workpiece from being scratched during processing. Scratched. The upper beam of the folding machine is usually wedge-shaped to form a gap so that a suitable shape of the blank can be folded into a quadrilateral box or groove.
The optimization of the overall production process of an enterprise is the desire of every enterprise because the optimization of the production process can ultimately reduce labour costs, improve work efficiency, and produce precision. Therefore, as people continue to deepen their understanding of bending machines and folding machines, the correct guidance and use of folding machines in the sheet metal industry is a direction for the improvement of the bending process.
The CNC press brake is suitable for large steel structure parts, iron towers, street lamp poles, high lamp poles, automobile beams, automobile cargo boxes and other related industries.
The CNC bending machine mainly adopts the structure of the sheet metal bending machine; it is composed of a fully closed-loop CNC system of the bending machine, two grating scales, a photoelectric encoder for real-time detection and feedback, and a stepper motor driving the screw rod to form a fully closed-loop control. Two grating rulers; one for the back gauge and the other for real-time detection and feedback correction of the position of the slider; the photoelectric encoder detects the position of the dead stop of the cylinder and feeds it back to the numerical control system.
The key to the pros and cons of bending depends on the two key parameters of bending angle and size. When bending, in order to better ensure the forming size and angle of the bending, the following problems must be paid attention to on many levels.
1.First, turn on the power, turn on the key switch on the control panel, and then press the oil pump to start, so you can hear the sound of the oil pump turning.
2.Stroke adjustment, the use of the bending machine must pay attention to adjusting the stroke, and be sure to test before bending. When the upper die of the bending machine descends to the bottom, there must be a gap of plate thickness. Otherwise it will cause damage to the mold and the machine. The stroke adjustment also has electric quick adjustment and manual stomach adjustment.
3.For the selection of bending notches, a notch with a width of 8 times the thickness of the plate is generally selected. If you bend a 4mm sheet, you need to choose a slot of about 32.
4.Backgauge adjustment generally has electric quick adjustment and manual fine adjustment.
5.Step on the foot switch to start bending, and you can release it at any time. When you release your foot, the bending machine will stop and continue to go down when stepping on it.
6.Strictly abide by the safe operation regulations for machine tool workers, and wear labor protection equipment as required.
7.Before starting, you must carefully check whether the motor, switch, circuit and grounding are normal and firm, and check that the control parts and buttons of the equipment are stuck in the correct position.
8.Check the overlap and firmness of the upper and lower molds; check whether the positioning devices meet the requirements of being processed.
9.When the upper sliding plate and each positioning axis are not at the origin, run the return-to-origin program.
10.After the equipment is started, it runs idle for 1-2 minutes, and moves on the slide full stroke 2-3 times. If there is any abnormal sound or malfunction, stop immediately, remove the malfunction, and work after everything is normal.
11.When working, one person should be in uniform command, so that the operator and the feeding and suppressing personnel should cooperate closely to ensure that the cooperating personnel are in a safe position before issuing the bending signal.
12.The sheet metal must be compacted when bending, to prevent the sheet material from lifting up and hurting people during the bending.
13.The power supply must be cut off when adjusting the sheet metal die, and the operation should be stopped.
14.When changing the opening of the variable lower tooling, no material is allowed to come into contact with the lower tooling.
15.Frequently check the overlap of the upper and lower tooling; whether the instructions of the pressure gauge meet the regulations.
16.Before shutting down, place wooden blocks on the lower tooling under the cylinders on both sides to lower the upper slide plate onto the wooden blocks.
17.Exit the control system program first, then cut off the power supply.
1.According to the company's current amount of working capital, you can buy a bending machine at a suitable price. There are many brands and types of CNC bending machines on the market. We should choose the right brand of bending machine according to our own funds and the precision of the workpieces produced. Some manufacturers produce machines that are cheap but low in processing accuracy, and some are expensive but high in processing accuracy and durable.
2.According to the material type, thickness, length and accuracy requirements of the main parts produced by the current business, select the appropriate bending machine. Try to choose a bending machine that can meet the current production requirements of various parts, and avoid using a single-function bending machine.
3.While meeting the current production needs, it is also necessary to consider the production needs that may arise in the future. Order changes must be fully recorded, and some unexpected orders must be fully prepared so that the company has sufficient adjustment capabilities-response time should be as short as possible. Therefore, it is necessary to purchase machines with slightly larger tonnage and longer working hours, which is conducive to business expansion. In general, it is more cost-effective to buy a larger machine with strong expandability than to add a new machine, which can effectively reduce the subsequent capital and land investment.
