High processing accuracy. The hole margin is 0.2mm, and the hole spacing is 0.5mm/m.
Since the turret is equipped with a variety of molds, the workpiece can be completely assembled at one time.
The machine can process the workpiece separately or batch-process the workpiece with the group command G98 to increase productivity.
The workpiece reaches the bending process after undergoing two processes of blanking and stamping. CNC bending machine has the advantage that ordinary machine tools can't match. Such as CASPRINI origin Italy, Siemens CNC system, the input method is manual programming, (1) through the control panel directly input the thickness, mold number, tensile strength, X-axis size, angle, workpiece length, stroke height to complete the preparation. (2) For some workpieces with high shape and high precision requirements, input 2D or 3D graphics through the control panel, board thickness, and mold number to determine the bending sequence generation program by using the function of human-machine dialogue. After the program is generated, it is stored in the program buffer area. Now it needs to be stored in the machine memory. If the program needs to be used repeatedly, it will be copied out through the dedicated disk. The CNC bending machine usually has two front and rear towing racks, and the numerical control system controls the root rejection angle to determine the lifting height of the towing rack, thus reducing the labor intensity of the operator. The ordinary CNC bending machine has two servo motors to drive the X-axis and Y-axis of the machine. The detecting component adopts a grating ruler, an inductive synchronizer, an encoder and the like, which are usually installed on the screw of the machine tool, and the detecting feedback device converts the displacement amount of the screw into an electric signal, and feeds back to the numerical control device if there is a error of 0.02 mm with the command value. , then control the lead screw to make adjustments. The high-performance bending machine installs a motor on each side of the X-axis so that the X-axis can machine the bevel. A motor is mounted on each of the shafts to machine workpieces at different angles on both sides. Adding a motor under the tailgate makes it possible to move the tailgate up and down more conveniently. The ordinary upper-type bending machine is bent by the long-term use of the hydraulic system on the machine tool. Therefore, the numerical control bending machine installs a hydraulic system under the machine tool. When the upper and lower molds work with each other, the system applies force to the lower mold. The deformation of the small lower mold extends the use time of the lower mold.
The characteristics of CNC bending machine:
(1) After the program is established, it can work automatically or semi-automatically. The automatic cycle of the program makes the workpiece complete once, which changes the inconvenience of large batch size and complicated process during semi-automatic machining.
(2) The CNC system automatically calculates the oil pressure to avoid damage to the machine tool caused by overpressure.
(3) The introduction of 2D and 3D graphics input functions facilitates the processing of complex workpieces and improves processing efficiency.
(4) The addition of various devices improves the processing process and reduces the labor intensity of the operator.
With the extensive application of sheet metal machinery in aerospace, railway transportation, environmental protection equipment, air conditioning electrical appliances, tobacco machinery, packaging and printing, engineering machinery, textile machinery and many other industries. Sheet metal processing also requires more high-tech workers to operate, good equipment and excellent staff to produce good products, so that there are more excellent Chinese-made products in the world.
