Abstract
The invention discloses an electro-hydraulic control multi-cylinder linkage bending machine which mainly comprises oil cylinders, wall plates, connecting beams, an oil tank, sliding blocks, a workbench, a mould, a hydraulic system, an electrical system, a numerical control system and the like. The single equipment comprises one hydraulic assembly and two synchronous blocks; two grating scales are respectively arranged on two sides of the machine; the synchronous operation of the sliding blocks is detected, data is fed back to the numerical control system, and four oil cylinders are controlled by servo valves to bend synchronously downwards. Due to the adoption of the device, the cost of the materials needed by the synchronous bending of two cylinders is saved greatly, the product bending effect is improved, and the difficulty of purchasing the raw materials (steel) is reduced.
Description
Technical field
The present invention relates to bender field, concrete is a kind of electrichydraulic control multi-cylinder interlock bender.
Background technology
Bender is for the bending and molding to panel beating material, there is the distinguishing features such as economy, safety, efficient and energy-saving and environmental protection, thereby, the development of bender is paid much attention in countries in the world, current bender at home and abroad generally adopts two cylinder bendings, sometimes large during with ten meters in length, adopt two-shipper four cylinder interlock bendings, but because length is long, two wallboard spans are excessive, so excessive to the upper and lower modification in the centre of workbench and slide block, also can cause the middle front and back of slide block bending, often Angular Dimension and the linearity of processing plate are not reached to requirement.
Summary of the invention
The invention provides one under equal length and bending power, two-shipper adopts eight cylinder Synchronous Bending, and multiple spot is stressed, and the workpiece angle error after bending and molding is little, the electrichydraulic control multi-cylinder interlock bender that linearity is good.
Technical scheme of the present invention:
Electrichydraulic control multi-cylinder interlock bender, comprise under-chassis plate, wallboard, on under-chassis plate, fixedly mount frame, under-chassis plate, workbench, electric system, digital control system are installed in frame, it is characterized in that: described wallboard has eight, between every two blocks of wallboards, fuel tank is installed, and is fixedly connected with by tie-beam between wallboard, fuel tank and tie-beam be four blocks of wallboards described frame of composition that links together, and two frames become one group and connect by synchro switch; Described under-chassis plate, by adjustment block connecting working table, is provided with mould on described workbench; On eight blocks of described wallboards, oil cylinder is all installed, synchronous valve, prefill valve, prefill valve, synchronous valve, synchronous valve, prefill valve, prefill valve, synchronous valve are installed respectively on described oil cylinder from left to right successively; On the little facade of described wallboard, be all installed with on track plate track plate and be slidably fitted with the slide block being connected with cylinder piston rod.
Described electrichydraulic control multi-cylinder interlock bender, is characterized in that: described synchronous valve, prefill valve, synchronous valve, oil cylinder forms a part for hydraulic system, is connected with Oil pump electrical machinery fuel feeding, and a pressure valve and grating scale are installed in each frame.
Advantage of the present invention:
In order effectively to guarantee fruit of bending, under equal length and bending power, two-shipper adopts eight cylinder Synchronous Bending, and multiple spot is stressed, and the modification amount of workbench and slide block reduces greatly, and the workpiece angle error after bending and molding is little, and linearity is good.
From cost, greatly fall at the end the needed material of original two cylinder Synchronous Bending, the effect of bending product has been improved on the contrary,, raw material steel buying difficulty has been fallen at the end on year-on-year basis meanwhile.
