Abstract
The invention relates to a multifunctional hydraulic system of a bar material bender. The multifunctional hydraulic system comprises a hydraulic pump, electromagnetic directional valves and a pilot overflow valve and is characterized in that the hydraulic pump comprises a duplex hydraulic pump (2) and a duplex hydraulic pump (3) which are connected with a filter after being connected in parallel; the duplex hydraulic pump (2) is connected with one three-position four-way electromagnetic directional valve in series; one overflow valve is connected between the duplex hydraulic pump (2) and the three-position four-way electromagnetic directional valve; the three-position four-way electromagnetic directional valve is directly connected with a leftward-bent hydraulic cylinder and also connected with the leftward-bent hydraulic cylinderby virtue of a one-way throttle valve; the duplex hydraulic pump (3) is respectively connected with the pilot overflow valve, the second three-position four-way electromagnetic directional valve and a two-position four-way electromagnetic directional valve; the pilot overflow valve is connected with a two-position two-way electromagnetic directional valve in series; the second three-position four-way electromagnetic directional valve is directly connected with a rightward-bent hydraulic cylinder and also connected with the rightward-bent hydraulic cylinder by virtue of a one-way throttle valve; the two-position four-way electromagnetic directional valve is directly connected with a compaction hydraulic cylinder and is connected with a speed control valve in series; a two-position two-way electromagnetic directional valve is connected between the two-position four-way electromagnetic directional valve and the speed control valve. The multifunctional hydraulic system is simple in structure and less in generated heat, and can be used for saving energy sources.
Description
Technical field
The present invention relates to hydraulics field, relate in particular to the hydraulic system being applied in multi-functional bar bender.
Background technique
Multi-functional bar bender is the Bending Processing of 4.5 to 12mm metal bar material goods for diameter.This machine can process more than ten and plant different shape and size, has the finished product of three tortuosity can a squeeze job moulding, and product is without impression.In an extrusion process, can realize the extrusion modling simultaneously of many bars.This machine is made up of main frame, hydraulic station and electric control cabinet three parts.
The main frame of machine is made up of frame, portal frame etc.Left bending mechanism can be realized two curved once-throughs, and wherein the bending of handle place is by the spacing realization of portal frame upper limit axle.Right bending mechanism is arranged on a support body that can slide along cross slide way, unclamp lock bolt, shake leading screw can be adjusted the curved position of right folding, to meet the requirement of products of different specifications, left folding bending apparatus, right folding bending apparatus and pressure strip are each adopts a single-piston-rod hydraulic cylinder to drive, the pressure of the left and right bending oil hydraulic circuit of hydraulic system and speed must have adjusting alone, the feature of mutual noninterference.
Summary of the invention
