简体中文 At a time when the cost of manufacturing land is surging, theLift tables have been transformed from vertical handling tools to space value amplifiers.-- By accurately linking the upper and lower workpiece plate flows of the double-layer multiplier chain, it allows a single production line to achieve an implicit capacity release of 30%, while compressing the comprehensive O&M costs by 15%.
I. Core function: the power heart of the vertical circulation system
Lift tables fulfil a triple mission in double-deck speed chain systems::
- vertical transfer: The cylinder-driven jacking mechanism (stroke accuracy ±0.3mm) enables precise switching of the workpiece between the upper production layer and the lower reflow layer.
- Flow controlBuilt-in guiding mechanism (roller clearance ≤ 0.5mm), together with the blocker to achieve 90 ° steering diversion of the workpiece, to avoid interference with the wire frame.
- pressure shiftThe design of the support platform spreads the fixture pressure to the frame, reduces the direct force on the doubler chain, and prevents the chain from deformation (40% life expectancy under heavy-duty scenarios).
