Automatic bending machine can perform multi - step display function, also can realize the automation program. It contributes greatly to the improvement of production efficiency. Because the Hydraulic Pipe Bender adopts steel plate welding frame, it can eliminate the stress when shaking. Similarly, hydraulic pipe bender is the top seal imported, so they are safe and reliable. The main working mode of most pipe bender is top piston press, and its driving pressure has obvious characteristics, which has a wonderful relationship with the production process of pipe bender mould. But there is no denying that pipe bending devices are safer to manufacture. Safety considerations in normal use include:
The working quality of the Automatic Pipe Bender is caused by the stress of two hydraulic cylinders working in parallel, and the stress drops vertically. Stress can drive the mold and mold that bend the beam to perform the bending work. The common buckling process of the up-buckling beam has many stages and many links, including descending activity, static and decompression, return trip, etc.
Hydraulic Pipe Bender
The rapid closing movement of the common pipe bender is usually free falling, which is caused by the weight of the pipe bender itself. However, this is not the case with CNC pipe bender mold and mold manufacturing, but the use of hydraulic cylinder without pole caries to generate pressure, so the fast forward speed can reach 250mm/s, more suitable for manufacturing more power of the mold. The mold.
The rest of the automatic bending machine is the top bending beam at the top dead center. This state is intended to deter uncontrolled downward activity and reduce security threats.
The precision of the workpiece can be improved when the vacuum cavity begins after the residence time or when the BDC is reached. Both the holding pressure and the falling pressure can be adjusted by symmetrical direction closure. The running cycle time can be adjusted as needed. When decompression is required, it can be reduced as much as possible, but the decompression profile should not be too steep and should be as smooth as possible.
This involves a large return rate, which depends largely on the pump circulation and the stressed area of the hydraulic cylinder chamber. In general, the closer to the fast speed, the more efficient the return. The return trip also requires synchronization.
The next stage is marking and bending, which is an essential and final step in the mold production of the Pipe Bender. The stamping speed is limited by the oil supply of the oil pump, in addition, it is also subject to the manual intervention of the proportional valve direction closing.
