Abstract
The invention relates to the technical field of hydraulic machine devices, in particular to a four-corner leveling device of a novel rapid hydraulic machine. The four-corner leveling device comprises an oil cylinder, a piston rod, a piston and a flange. Leveling cylinders are arranged below the piston and fixedly installed on the four corners of the lower end of a hydraulic machine body. Displacement sensors are arranged at the bottom portions of the leveling cylinders and connected with a control assembly. By the adoption of the structure, when sliding block assemblies of the hydraulic machine move downwards to be combined with a die, adjustable threaded rods on the four corners of the sliding block assemblies make contact with the four leveling cylinders, workpieces to be pressed are prevented from unbalance loading, it is guaranteed that the thickness of the pressed workpieces is uniform and the same, pressed product scrap is avoided, product quality is effectively improved, and production cost is reduced.
Description
Technical field
The present invention relates to hydraulic press equipment technical field, be specifically related to the four-corner leveling device of novel high speed hydraulic press.
Background technology
At present, known frame hydraulic press, is mainly made up of the workbench and the movable slider assembly that are equipped with in the group frame of Plate Welding with mould.Because its structure design itself is unreasonable, cause the workpiece of suppressing in pressing process that unbalance loading phenomenon easily occurs, thereby make suppressed product thickness inconsistent, cause compacted products to scrap, reduce product quality, increase production cost.
Summary of the invention
The object of this invention is to provide and a kind ofly can prevent suppressed workpiece generation unbalance loading phenomenon, ensure that institute's compacted products even thickness is consistent, the four-corner leveling device of the novel high speed hydraulic press that effectively improves the quality of products, reduces production costs.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: the four-corner leveling device of novel high speed hydraulic press, comprise oil cylinder, piston rod, piston and flange, the below of described piston is provided with leveling cylinder, described leveling cylinder is fixedly mounted on four jiaos of hydraulic press frame bottoms, the bottom of described leveling cylinder is provided with displacement transducer, and described displacement transducer is connected with Control Component.
Further, described Control Component comprises PLC and servo ratio control valve, and described PLC is connected with servo ratio control valve.
Further, described oil cylinder is provided with oil-in and oil-out.
Further, between described oil cylinder mouth and piston rod, embed and have fairlead.
The present invention has following beneficial effect: the four-corner leveling device of novel high speed hydraulic press of the present invention, comprise oil cylinder, piston rod, piston and flange, wherein, below piston, be provided with leveling cylinder, described leveling cylinder is fixedly mounted on four jiaos of hydraulic press frame bottoms, simultaneously, the bottom of described leveling cylinder is provided with displacement transducer, and described displacement transducer is connected with Control Component; The present invention adopts said structure, when the descending mould of slide block assembly of hydraulic press soon in conjunction with time, four jiaos of adjustable screw rods of slide block assembly contact with four leveling cylinders, thereby can prevent suppressed workpiece generation unbalance loading phenomenon, slide block assembly downstream rate is fast, and ensure that institute's compacted products even thickness is consistent, avoid compacted products to scrap, effectively improve the quality of products, reduce production costs.
