4. The main transmission adopts a chain type bend pipe, which is stable.
5. The bending direction of the pipe fittings is from above, and the clockwise direction is rotated to the bending direction
Hydraulic components
1. Electromagnetic valve oil grinding
2. Hydraulic pump Yongling
3. Hydraulic pipe connection
4. Cylinder UN ring tripod base
5. Cylinder O-ring tripod base
6. Hydraulic cylinder self-made
Electric control part
1. Electric control system: Using well-known Japanese controllers.
2. Mitsubishi's ultra large CPU can accommodate 400 sets of file editing. Each file can be set with 16 bend angles, and the memory can store 60 sets of files
3. All processing materials have touch screen input.
4. It has the function of detecting errors and faults dynamically, and is displayed on the screen, making it easy for the operator to troubleshoot.
5. Each bend can have compensation values, speeds, and demolding gaps set according to different material changes.
6. The feeding method can be selected as direct or pinch feeding according to different needs.
7. Can automatically convert XYC coordinates into YBC machining values
8. After the data editing is completed, there is password protection to prevent arbitrary modification of the data.
9. The feeding position, safety position, clamping interference position, and guide interference position of the feeding trolley can be manually adjusted, and the position can be automatically memorized to eliminate human measurement errors and machine collision losses.
10. The feeding shaft will be automatically detected before operation to avoid collision with the machine.
11. During actual bending, decomposition action can be selected, interference points can be observed, and actions can be modified to improve production efficiency The machine has a communication interface and a data machine. Remote monitoring, troubleshooting, etc.
12. The Chinese manual for each hydraulic pipe bending machine includes (installation and maintenance operation manual, list of vulnerable parts, hydraulic schematic diagram, electrical schematic diagram, and mold diagram) one copy each
