Equipment Instructions

The ZBJ-G mobile roller ring disassembly series is a specialized four column Hydraulic Press designed for metallurgical rolling mills (high wire, bar, and profile). The core is a movable body+large tonnage press fit/disassembly+roller ring special fixture, which solves the quick disassembly and assembly of roller/roller ring/cone sleeve interference fit.

Product positioning and core advantages

Strong specificity: for the interference fit disassembly and assembly of roller rings cone sleeves roller shafts in high-speed wire/bar/profile rolling mills, replacing manual labor and simple tools.

Flexible mobility: The whole machine is equipped with walking wheels and tracks/trackless, which can move within the workshop and adapt to multi rack roller changing.

High efficiency: Disassembly and assembly of a single set of roller rings takes 5-10 minutes, significantly reducing downtime for roller replacement.

Safe and reliable: hydraulic self-locking, overload protection, manual operation to avoid the risk of workpiece ejection.

Structural and Mobile Design

Three beams and four columns+mobile base: rigid connection of upper beam, slider, and workbench; The base is equipped with a walking mechanism (motor-driven/manual), which can move along the track or the ground.

High rigidity body: steel plate welding+vibration aging, column quenching and tempering+hard chrome, anti eccentric load, high guiding accuracy.

Mobile mode:

Track type: Pre embedded steel rails in the workshop ensure smooth movement and accurate positioning.

Trackless: Solid tires+steering, flexible adaptation to trackless workshops.

Positioning locking: After being in place, hydraulic/mechanical locking is used to ensure the stability of the machine body during disassembly and assembly.

Hydraulic and control system (same as ZBJ series)

Plug in valve integrated system: sensitive action, small impact, low leakage, long service life.

Multi speed: fast down → slow work in → pressure holding → return, pressure/speed infinitely adjustable.

Power configuration: Main motor 30-55kW (by tonnage), meeting the requirements for fast operation of large tonnage.

PLC+touch screen/digital display: inch motion, single time, semi-automatic; Fixed distance/fixed pressure dual process, pressure holding delay.

Safety circuit: hydraulic lock, overload protection, emergency stop, dual hand button, limit.

Special function for disassembling and assembling roller rings

Special tooling: comes standard with roller ring pressing sleeve, cone sleeve top rod, and positioning seat, suitable for different specifications of roller rings (diameter 200- diameter 600mm).

Bidirectional force: The main cylinder is disassembled/assembled by pressing down, and the lower top cylinder pushes out the workpiece to complete interference separation/pressing.

Alignment accuracy: The workbench is equipped with positioning slots/adjustable V-shaped blocks to ensure that the roller shaft is coaxial with the slider, preventing eccentric load and strain.

Auxiliary functions: Optional hydraulic rotary table, roller ring lifting fixture, cooling/heating auxiliary interface.
