Hydraulic press brake bending machine for Sale in 2023 includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate through a hinge. It consists of a cover plate, the coil is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate. When in use, the wire is energized to the coil, and after energization, an attractive force is generated on the pressure plate, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and it can also process workpieces with side walls.

Hydraulic press brake bending machine for Sale Lifting and Installation
1. The center of gravity of the hydraulic sheet metal bending machine is relatively high, and the front is heavy and the rear is light. Therefore, it is necessary to pay attention to the position of the center of gravity during lifting, handling and installation, so as to avoid machine overturning accidents. When lifting, the included angle of the lifting wire should be as small as possible. , so as to keep the accuracy of the machine tool constant.
2. The left and right columns of the hydraulic sheet metal bending machine are located on the working table as the benchmark for measuring the level, and the vertical and horizontal directions should be less than or equal to 1000:0.2. The foundation is prepared in advance according to the foundation map, and the hydraulic sheet metal bending machine is installed on the foundation At the same time, install the anchor bolts, and finally grout. After the cement is completely solidified, tighten the bolts and check the level.
Hydraulic press brake bending machine hydraulic control form
1. Central control block
The form of the central control block is to synthesize three control blocks into one control block. It is mainly used in some special structure bending machines. Due to control reasons, the connecting pipes between the control block and the two stamping hydraulic cylinders must be symmetrically arranged, and the maximum allowable distance between the two hydraulic cylinders must be guaranteed (about 3m). Therefore, the central control block should be arranged as much as possible in the center of the machine.
2. Three control blocks
This style features three control blocks. The two main control blocks with associated intermediate plate filling valves are mounted directly on the hydraulic cylinders, enabling a pipe-free connection between the main control blocks and the cylinder chamber. The main control block of the bending machine is mainly composed of important proportional directional valves, position monitoring directional valves and back pressure components.
3. Interface distributor for sensor and shaft
In the application of the bending machine, the central control block concentrates all the solenoid valves in one control block. Similarly, the electrical connections of each valve are concentrated on one cable to realize the common connection. For this reason, an interface distributor is also set up on the central control block of the bending machine.
