Abstract
The invention provides the hydraulic system of a kind of bender, the filter including fuel tank, being connected on fuel tank, the hydraulic pump being connected with filter, the three-position four-way electromagnetic directional valve being connected with hydraulic pump, the hydraulic cylinder being connected with three-position four-way electromagnetic directional valve, the pressure switch being connected with hydraulic cylinder and travel switch；Described hydraulic pump includes oil distribution casing, the cylinder body being connected with oil distribution casing, the plunger piston slippery boots being connected with cylinder body, the return plate being enclosed within outside plunger piston slippery boots, the power transmission shaft being located in cylinder body, plunger piston slippery boots, is enclosed within the thrust plate outside power transmission shaft.The present invention has the following technical effect that the hydraulic system of the present invention, for bender, can be greatly shortened the adjustment time, improves work efficiency.
Description
Technical field
The present invention relates to the hydraulic system of a kind of bender, belong to technical field of mechanical equipment.
Background technology
Bender is a kind of machine that thin plate can carry out bending, and its structure mainly includes support, workbench and clamping
Plate, workbench is placed on support, and workbench is made up of base and pressing plate, and base is connected with clamping plate by hinge, and base is by seat
Shell, coil and cover plate composition, coil is placed in the depression of a shell, and recessed top is covered with cover plate.By wire, coil is led to during use
Electricity, produces gravitation, thus realizes the clamping of thin plate between pressing plate and base pressing plate after energising.Owing to have employed electromagnetic force folder
Hold so that pressing plate can make various workpieces requirement, and can be processed the workpiece having sidewall, the simplest in operation
Just.
Bending is process complicated in metal blank processing, only has the operator of high degree of skill on common bender
High-quality part can be produced, but also need the long adjustment time.It is thus desirable to provide a kind of high-quality
Hydraulic system, shortens the adjustment time.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that the hydraulic system of a kind of bender.
The hydraulic system of the bender of the present invention, the filter including fuel tank, being connected on fuel tank, the liquid being connected with filter
Press pump, the three-position four-way electromagnetic directional valve being connected with hydraulic pump, the hydraulic cylinder being connected with three-position four-way electromagnetic directional valve and hydraulic pressure
Cylinder be connected pressure switch and travel switch；Described hydraulic pump includes oil distribution casing, the cylinder body being connected with oil distribution casing and cylinder body
Be connected plunger piston slippery boots, the return plate being enclosed within outside plunger piston slippery boots, the power transmission shaft being located in cylinder body, plunger piston slippery boots, be enclosed within power transmission shaft
The thrust plate in outside.
Described fuel tank is provided with electromagnetic relief valve；It is connected with piezometer on described electromagnetic relief valve；
It is connected with motor on described hydraulic pump.
The present invention have the following technical effect that the hydraulic system of the present invention for bender, when can be greatly shortened adjustment
Between, improve work efficiency.
