Horizontal Hydraulic Wheel Press Machine
pre
The hydraulic sleeve press is specifically designed for the pressing and unpressing of wheel sets used in railway locomotives and vehicles,subways,trams,mining and metallurgical transportation.It can also be used for pressing operations of motor rotor shafts,bushings,bearings,gears and other parts.
This press machine is mainly applied in wheel workshops,vehicle depots,electric locomotive manufacturing plants and related production enterprises.
Horizontal Hydraulic Wheel Press Machine Structure and Main Parts
Core advantages of the equipment(key features adapted to scene requirements):
Precise and controllable pressure:It adopts a hydraulic transmission system,which can adjust the pressing force acccording to the specifications of the wheel set and the fit tolerance of the parts(ranging from several thousand KN to tens of thousands of KN),avoiding over-pressing damage to the journal or under-pressing leading to loose assembly.
Strong adaptability:It can be compatible with wheel sets of different sizes(from smallmetro wheel sets to heavy -duty mining wheel sets)and various mechanical parts,and can switch between multiple scenarios by replacing the positioning fixtures.
High stability:To meet the high-precision requirements of wheeel set pressing,it is equipped with a guiding mechanism and postioning device to ensure the concentricity of the wheel and axle during the pressing process and reduce assembly deviations.
Multi functional:It has both "pressing" and "unpressing"functions,meeting the dual needs of production assemblyand maintenace,and improving the utilization rate of the equiipment.
In large-scale wheel and axle assembly scenarios in industries such as automotive manufacturing, rail transportation, and heavy machinery, wheel and axle press-fitting machines often need to work in conjunction with cranes (such as bridge cranes and gantry cranes). The core of their collaboration lies in resolving the connection issue between "heavy object transportation" and "precise assembly" - the crane is responsible for transporting the heavy wheel and axle components (such as train wheels with a diameter of over 1 meter and engineering machinery hubs weighing over 500 kg) to the press-fitting machine position and assisting in positioning, while the press-fitting machine completes the high-precision press-fitting operation, forming an efficient "transportation - positioning - assembly" closed-loop operation.
Core application fields:
Rail transportation equipment.Specifically designed for the press-fitting and removal of wheelsets in rail vehicles,covering all types of rail vehicles:
-Mainline railways:Assembly and maintenace of wheelsets for railway locomotives and vehicles(passenger locomotives,freight trains,EMUS),including press-fitting of rims and journal,and removal of bearings from used wheelsets
-Urban rail:Press -fitting operations for wheelsets of metro trains and trams(must adapt to the compact dimension and high precision requirements of urban rail vehicle wheelsets
-Specialized rail:Press-fitting of wheelsets for underground mining transport vehicles and specialized transport wheelsets in metallurgical plants(must meet the high intensity press-fitting demands in haarsh working conditions,such as the assemble of bearings for heavy-duty wheelsets)
Extended application scenarios:
General mechanical parts press-fitting.Besides the core rail applications,it can also be used for precise press-fitting of general mechanical parts,including:
-Shaft parts:Press-fitting of motor rotor shafts with cores,and couplings
-Sleeve parts:Press-fitting of sleeves with housings,and shafts sleeves with bases(for interference fits)
-Transmission parts:Press-fitting of bearings with shaft shoulders,and gears with transmission shafts (must match the pressure and stroke requirments of different specifictions of pars
