Hydraulic press for street light pole
Features of machine:
Fully welded construction is made of qualified steel plates, whose stress is relieved by hot temperature to prevent from the deformation.
C type structure can ensure the out-feeding of workpiece at the throat.
The guiding of slide block is by round guide rail with high rigidity.
The slide block is connected with piston rod of oil cylinder, which move up and down depending on the guiding of 6 guide columns. The outside surface of 6 guide columns is hardened and chromed with high precision and rigidity.
There are T slotting on working table and slide block so as to install the light pole tooling.
Overall all pressure is achieved by 2×100t of oil cylinders. The piston rod of oil cylinder connects slide block by flange. The cylinder body is qualified forging steel.
The surface of piston rod is hardened by middle frequency heat treatment. Seal rings in oil cylinder are from Japan. The oil cylinder makes the pressure testing before installation.
The closed shape oil tank is with Cleaning oil window and Drain oil plug, which is designed at the top of machine. There are the connecting-proof type oil suck oil filter at the inlet port of oil pump to ensure the oil cleanliness and life of oil pump and valve group.
Hydraulic system is arranged inside of machine. The hydraulic system is characterized by pre-unloading of over-pressure and small hydraulic impact.
Independent electrical cabinet set in the right of machine.
Centralized control panel with power indicator, starting motor indicator, working indicator, operating button, change over switch etc.
- Emergency stop button to stop machine when abnormal situation happens
- Over-loading protection by safety valve in hydraulic system
- Adopts proximity switch at speed change over point, adjustable top limit position point and fixed stroke point
with high sensitivity.
- Top and bottom limit of oil cylinder controlled by stroke switch
