The control system of the ejector device of the ultra-long stroke gantry mobile hydraulic press

Abstract

The invention discloses a control system for ejection devices of an ultra-long-stroke gantry movable hydraulic press. By recording the coordinate information of a small vehicle moving in the Z-axis direction and a big vehicle moving in the X-axis direction in the gantry movable hydraulic press and comparing the data of the coordinate information and the data of the coordinate range, preset in a programmable logic controller program, of the each work region of the ejection devices, the coordinate region of the corresponding ejection device when the small vehicle and the big vehicle stops movingis determined, ascending and descending of the ejection device in the region are achieved, and the ejection devices in other regions do not move. By the adoption of the ultra-long-stroke gantry movable hydraulic press, the intelligent control over the ejection devices on a worktop is achieved, the problem of the high-intensity labor required for the manually frequent adjustment of an existing gantry movable hydraulic press is solved, the energy consumption is saved, the production efficiency is improved greatly, and the labor cost is improved greatly.

Description

technical field [0001] The invention relates to the technical field of hydraulic presses, in particular to a control system for an ejection device of a super-long-stroke gantry mobile hydraulic press, which is suitable for super-long-stroke gantry mobile hydraulic presses. Background technique [0002] Now the demand for large-area panels and components in the domestic power manufacturing industry is increasing, so the demand for gantry mobile hydraulic presses such as ultra-long and ultra-wide worktables will increase. Due to the increase of the working surface, the number of corresponding ejection cylinders will also increase significantly. At present, most of the domestic gantry mobile hydraulic presses use the working method of the ejector cylinder to fully eject the workpiece and retract it to drop the workpiece. If this is still the case, the time required for the ejection and retraction of the ejector cylinder will be greatly increased. Increase, and the waste of ele...

Problems solved by technology

[0003] Due to the large area of ​​the workpiece or the shape of the component, the gantry mobile hydraulic machine needs to manually change the use area frequently, and then perform the leveling work of the workpiece or component, so the cycle goes back and forth, and the workpiece that has been leveled cannot be placed on the work surface. Using the function of automatic ejection of the area also caused unnecessary waste of time
