Hydraulic Drive; Lift/Clamp Force By Model - Dukane VWA-4300 User Manual

Linear Vibration Welder 4000 Series, Model VWA User's Manual

Hydraulic Drive

Self–Contained System
The lift table is raised and lowered by hydraulic pres-
sure. The hydraulic system has its own motor, pump,
filter, reservoir, cooling system and programmable regu-
lator. The valves and pressure regulator are controlled
by parameters contained in a setup file and controlled by
the welder's PLC.
The drive unit is shown in Figure 3-10. The hydraulic
pump is capable of generating a maximum of 1,500 psi
(102 bar). The pressurized fluid drives a hydraulic cylin-
der which is located under the table and has a maximum
stroke of 20 inches (508 mm). The maximum lift or clamp
force available at the piston is a function of the hydraulic
cylinder diameter. The specifications for each model are
given in Table 3-II. The maximum programmable force
is less than the available
shown in Section 6 – Page 65.
