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 the bender field, concrete is a kind of electrichydraulic control multi-cylinder interlock bender.
Background technology
Bender is what to be used for to the bending and molding of panel beating material, has 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, and at home and abroad bender generally adopts two cylinder bendings at present, and is big during with ten meters in length sometimes; Adopt two-shipper four cylinders interlock bending; But because length is long, two wallboard spans are excessive, so excessive to modification about the centre of workbench and slide block; Front and back are crooked in the middle of also can causing slide block, and often Angular Dimension and the linearity to the processing plate do not reach requirement.
Summary of the invention
The invention provides a kind ofly under equal length and bending power, two-shipper adopts eight cylinder Synchronous Bending, and multiple spot is stressed, and the workpiece angle error behind the 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 comprises under-chassis plate, wallboard, fixedly mounts frame on the under-chassis plate; Under-chassis plate, workbench, electric system, digital control system are installed on the frame; It is characterized in that: described wallboard has eight, between per two blocks of wallboards fuel tank is installed, and is fixedly connected through tie-beam between the wallboard; Fuel tank and tie-beam link together four blocks of wallboards and form described frame, and two frames become one group also to connect through synchro switch; Described under-chassis plate connects workbench through the adjustment piece, on the described workbench mould is installed; On described eight blocks of wallboards oil cylinder is installed all, synchronous valve, prefill valve, prefill valve, synchronous valve, synchronous valve, prefill valve, prefill valve, synchronous valve are installed respectively on the described oil cylinder from left to right successively; All be installed with on the little facade of described wallboard on the track plate track plate and be slidingly fitted with the slide block that is connected with the oil cylinder piston bar.
Described electrichydraulic control multi-cylinder interlock bender, it is characterized in that: described synchronous valve, prefill valve, synchronous valve, oil cylinder are formed the part of hydraulic system, are connected with the Oil pump electrical machinery fuel feeding, and a pressure valve and grating chi are installed on 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 behind the bending and molding is little, and linearity is good.
From cost, fallen at the end the needed material of original two cylinder Synchronous Bending greatly, the effect of bending product has been improved on the contrary, simultaneously, raw material steel buying difficulty has been fallen at the end on year-on-year basis.

The specific embodiment
Referring to accompanying drawing, electrichydraulic control multi-cylinder interlock bender comprises under-chassis plate 14, wallboard 17; Fixedly mount frame on the under-chassis plate 14, under-chassis plate 14, workbench 11, electric system 8, digital control system 9 are installed on the frame, wallboard 17 has eight; Between per two blocks of wallboards 17 fuel tank 3 is installed; And be fixedly connected through tie-beam 6 between the wallboard 17, fuel tank 3 links together four blocks of wallboards 17 with tie-beam 6 and forms described frame, and two frames become one group also to connect through synchro switch 18; Described under-chassis plate 14 connects workbench 11 through adjustment piece 13, and mould 10 is installed on the workbench 11; On eight blocks of wallboards 17 oil cylinder 1 is installed all, synchronous valve 7, prefill valve 5, prefill valve 5, synchronous valve 7, synchronous valve 7, prefill valve 5, prefill valve 5, synchronous valve 7 are installed respectively on the oil cylinder 1 from left to right successively; All be installed with track on the wallboard 17 little facades; 12; Be slidingly fitted with the slide block 2 that is connected with oil cylinder 1 piston rod on the track plate 12; Synchronous valve 7, prefill valve 5, synchronous valve 5, oil cylinder 1 are formed the part of hydraulic system, are connected with Oil pump electrical machinery 16 fuel feeding, and a pressure valve 4 and grating chi 15 are installed on each frame.
Electrichydraulic control multi-cylinder interlock bender includes 1, eight oil cylinder of oil cylinder and is installed in respectively on eight blocks of wallboards 17; By fuel tank 3 and articulated beam 6 four blocks of wallboards 17 be linked together forms frame, workbench 11 is installed in the frame Lower Half, by adjustment piece 13 adjust frames and workbench 11 evenly stressed; Again by the whole frame level of under-chassis plate 14 adjustment; Slide block 2 is installed upper rack, drives slide block by oil cylinder and moves up and down, and four track plates 12 are installed on the frame; Four fulcrums are in line and the slide block applying, reduce the front and back of slide block crooked.
The whole hydraulic system of equipment; By Oil pump electrical machinery 16 fuel feeding; Through pressure valve group 4 synchronous valve group 7 to the oil cylinder of unit both sides, owing to be connected in parallel the epicoele of two oil cylinders on both sides, four oil cylinders of separate unit are two the oil cylinders installations in both sides synchronous valve group wherein; Middle two cylinders are plunger case, and prefill valve 5 oil suctions only are installed.
The electric system 8 installation right sides of machine, digital control system 9 is installed on the suspension bracket, and grating chi 15 is installed on the both sides wallboard of single machine; After the operation of lubricant pump motor, set digital control system numerical value, make slide block drive mould 10 bending downwards fast; The fluid that this moment, oil pump was confessed arrives separate unit both sides synchronous valve group again through the pressure valve group, gets into the epicoele of four oil cylinders, and the fluid of separate unit both sides oil cylinder cavity of resorption is through the quick oil sump tank of synchronous valve group; Eight oil cylinder epicoeles of two-shipper produce and inhale sky simultaneously, and owing to the prefill valve on eight oil cylinders is an open type, a large amount of fluid sucks the oil cylinder epicoele through prefill valve; After arriving speed change point, measure two machine slide positions by synchro switch 18, controlling the synchronous valve group again by digital control system, to make cunning hit piece descending at a slow speed; Behind the mould bending plate shaping, slide block rises and accomplishes a bending.
