CNC bending machines are suitable for processing large steel structure parts, iron tower, street lamp pole, high lamp pole, automobile beam, automobile container and other related industries.
The essence of NC bending machine is the die of NC bending machine, which is composed of bracket, worktable and clamping plate. The coil is electrified to generate the attraction to the pressing plate, so as to complete the clamping of the thin plate between the pressing plate and the base. Because the electromagnetic force clamping method is adopted, the pressing plate is made according to the specific requirements of the workpiece, and the operation is simple, and the workpiece with side wall can be processed.
There are different models of CNC bending machines, such as G-type, F-type, wc67k type, etc. CNC bending machine for plastic sheet is developed according to the principle of heating, softening, melting and welding of plastic sheet. It is suitable for the bending angle of all thermoplastic materials.. CNC plastic plate bending machine mold has the following characteristics: direct bending, no splicing, no slotting, no welding rod, its corner appearance is beautiful and watertight, at the same time, the processing speed is fast, the corner processing surface is beautiful, and the strength is high. It changes the manual welding into automatic machine operation, improves the quality, improves the labor efficiency, and reduces the labor cost, Greatly shorten the production cycle of products.
CNC bending machines
Features of WE67Y/K series CNC bending machines:
It mainly adopts WE67yk series sheet metal bending machine structure; The full closed-loop control system consists of SDS-3PB bending machine full closed-loop numerical control system, two grating rulers, a photoelectric encoder real-time detection feedback and stepper motor driving screw rod. Two grating rulers; A pair of back stop material, a pair of slider position real-time detection feedback correction; The photoelectric encoder detects the position of the dead block of the oil cylinder and feeds it back to the numerical control system.
Direct angle programming, with angle compensation function.
The grating ruler real-time detection feedback correction, full closed-loop control, back stop and slider dead stop positioning accuracy is 100% ± 02mm。
The upper die adopts fast clamping device, and the lower die adopts wedge deformation compensation mechanism.
With multi-step programming function, it can realize multi-step automatic operation, complete one-time processing of multi-step parts, and improve production efficiency.
According to the user’s demand, the imported hydraulic system with stable performance and compact structure can be selected, and the ball screw and synchronous belt drive can be selected for the rear stop.
Operating procedures
Strictly abide by the safety operation regulations of machine tool workers, and wear labor protection articles according to the regulations.
Before starting, the motor, switch, line and grounding shall be carefully checked for normal and firm, and check that all the operating parts and buttons of the equipment are stuck in the correct position.
Check the coincidence degree and firmness of upper and lower die; Check whether the positioning devices meet the requirements of machining.
When the upper slide plate and each positioning axis are not in the state of origin, run the back to origin program.
After the equipment is started, the equipment shall be transported by air for 1-2 minutes, and the upper sliding plate will move for 2-3 times. If abnormal sound or fault is found, stop immediately, and the fault shall be eliminated and all normal can be operated.
One person shall be in charge of the work, so that the operator and the feeding and pressing personnel cooperate closely to ensure that the coordination personnel are in safe position before the bending signal can be sent.
The plate must be compacted when bending to prevent the bending of the plate from warping and hurting people.
When adjusting the material and pressing die, the power supply must be cut off and it shall be carried out after it stops running.
When changing the opening of the variable lower die, no material is allowed to contact the lower die.
When working, no one is allowed to stand at the back of the machine tool.
It is strictly forbidden to press the folding sheet material at one end separately.
If the workpiece or die is found to be incorrect during operation, stop the machine and correct it. It is strictly forbidden to use manual correction during operation to prevent hand injury.
It is forbidden to fold the super thick iron plate or quenched steel plate, high-grade alloy steel, square steel and the plate material which exceeds the performance of the plate bending machine to avoid damaging the machine tool.
Check the coincidence degree of upper and lower die frequently; Whether the indication of pressure gauge meets the requirements.
Stop the machine immediately in case of any abnormality, check the cause and eliminate it in time.
Before shutting down, place the wooden block on the lower mold under the cylinder on both sides to lower the upper sliding plate onto the wood block.
Exit the control system program first, and then cut off the power supply.
