▼ Rack section
The rack is assembled into a whole frame by welding left and right columns, fuel tanks, and support blocks, and the workbench is securely connected to the lower part of the left and right columns.
▼ Slide section
The slider part consists of a slider, an oil cylinder, and a mechanical stopper fine adjustment structure. The slider adopts an integral panel and a dual guide rail structure for guidance. The left and right oil cylinders are fixed on the frame, and the piston (Xuan) drives the slider to move up and down through hydraulic pressure.
The mechanical stopper is built into the top of the two oil cylinders, with a compact structure and synchronized adjustment on both sides. When the slider (upper mold) is uneven, stop the slider at the top dead center, disengage the coupling sleeve of the synchronous transmission shaft on both sides of the mechanical stopper, and drive either side of the worm gear box in the upper part of the left and right oil cylinders (forward or reverse). Then press the slider to the bottom dead center, measure and adjust (repeat the above action) until the slider (upper mold) is equal in height on both sides, and finally position and install the coupling sleeve.
▼ Synchronization mechanism
The dual machine linkage synchronization is a mechanical forced synchronization mechanism composed of a torsion shaft and an arm. The manual clutch operation between the two machine tools allows for single machine operation, with a simple structure, stable and reliable performance, and high synchronization accuracy.
▼ Rear material blocking mechanism
Operated by the button box in front of the workbench, the motor drives the material rack to move forward and backward, and the distance of movement is displayed by numbers, with a minimum reading of 0.10 millimeters. (Both front and rear positions have travel switch limits). The rear stopper moves left and right on the guide rail and can be locked. The stopper can be adjusted up and down, and the top rod can be adjusted back and forth. The top rod can rotate around the axis to prevent damage during bending. It is easy, fast, and has high material blocking accuracy.
▼ Bending accuracy compensation mechanism
The fine-tuning mechanism is located on the upper mold and is used for compensating and fine-tuning the upper and lower parts of the upper mold to ensure the accuracy of the bent workpiece. Sometimes, there may be slight deviations in the overall bending angle of the bent workpiece. In order to achieve better consistency in the bending angle, the mold fastening screws can be slightly loosened (note that the upper mold may fall off and damage the mold), and the diagonal blocks can be moved left and right to perform fine adjustments on the upper mold. Then, tighten the screws and try folding again until satisfactory requirements are met. Hydraulic compensation for the vertical plate of the machine tool worktable ensures the straightness of bending during bending.
▼ Machine tool electrical system
The overview of the main machine electrical control system is as follows:
Main power supply: 380V, 50HZ, three-phase, control power supply: 220V. The main circuit and each motor are equipped with automatic switches for short circuit protection and overload protection. The control circuit uses fuses for short-circuit protection. The main components of the machine are reliably grounded.
This machine has three working modes, which are selected by the universal switch SA3 as jog, single shot, and continuous. The machine operation is controlled by a foot switch, which is convenient and fast. This machine is equipped with power supply and machine working status indicator lights, and electrical components are made of Siemens. Line introduction, safe and easy to maintain.
▼ Machine tool hydraulic system
The hydraulic system consists of an electric motor, an internal gear pump, a valve group, an oil tank, and active hydraulic accessories. The hydraulic system of the machine tool can be used as a dual machine or a single machine.
The maximum working pressure of the hydraulic system is 25Mpa, which is set through the main circuit system. The hydraulic valve selected is Jianhu hydraulic valve, and all seals are made of Japanese Valka. The pipeline layout is simple, with less leakage and easy maintenance and debugging.
