Chinese utility model patent, number of patent application is 201220217415.0, patent application day is on May 15th, 2012, Authorization Notice No. is CN202539289U, authorized announcement date is on November 21st, 2012, this utility model discloses a kind of unit extended type four cylinder hydrolic plate bender, this utility model comprises the first oil cylinder, the second oil cylinder, the 3rd oil cylinder, the 4th oil cylinder, slide block, gantry base and patrix clamp system, and the first oil cylinder, the second oil cylinder, the 3rd oil cylinder and the 4th oil cylinder are separately fixed on a root post; First oil cylinder, the second oil cylinder, the 3rd oil cylinder, the 4th oil cylinder piston are separately connected mutually with slide block, the first above-mentioned oil cylinder, the second oil cylinder, the 3rd oil cylinder, the 4th oil cylinder synchronously drive slide block to move up and down, the precision of the utility model processing super long workpiece is high, solve the problem of Double-machine linkaging bending machine poor synchronization, compare Double-machine linkaging bending machine, do not need expensive synchronous control technique cost, production cost is low, and cost performance is high.This practicality is directed to the improvement of machine tool control system, does not discuss for the structure of machine tool component, the change of parts.
Summary of the invention
1. the technical problem that will solve
For the two cylinder Synchronization Control existed in prior art, when super-tonnage and ultra-wide plate, lathe overall structure is heavy, manufacture difficulty increases, and the very high problem of cost, the invention provides a kind of bender, when it can be implemented in satisfied equal tonnage, commensurateiy wide, lathe overall structure is gently changed, transport and install security high, cost is low.
2. technical scheme
Object of the present invention is achieved through the following technical solutions.
A kind of bender, comprise workbench and slide block, also comprise oil cylinder I, oil cylinder II, oil cylinder III and column, described column has 3, is arranged at below oil cylinder I, oil cylinder II and oil cylinder III respectively, connecting working table and 3 oil cylinders; Described oil cylinder I, oil cylinder II are connected with slide block with the piston rod of oil cylinder III; Oil cylinder I, oil cylinder II are connected by synchronizing shaft with oil cylinder III.
Further, piston rod and the slide block of described oil cylinder I, oil cylinder II and oil cylinder III are bolted to connection.
Further, described slide block is fixed with upper die of bending machine, described workbench is fixed with bender lower die.
Further, described slide block is connected with the frame of bender by rolling guide or rail plate.
Further, oil cylinder and column can be respectively 4-6, form 4 cylinder benders, 5 cylinder benders or 6 cylinder benders.
3. beneficial effect
Compared to prior art, the invention has the advantages that:
(1) use multi-cylinder to carry out the Synchronization Control of bender, can equal tonnage met, when commensurateiy wide, the lightweight of lathe overall structure, cost reduces;
(2) thickness of slab that the frame thickness of slab that bender adopts also adopts than original two cylinder benders is few, obtains material more simple, convenient;
(3) purchase raw material and in process, each side links such as installations are convenient, and the logistics used and erecting tools equipment can miniaturizations, reduce cost, operate more quick;
(4) carrying out in handling and lifting process, the light body of the entirety due to lathe, transport transhipment is safer, ensure that security when construction.
Accompanying drawing explanation
Fig. 1 is three cylinder bender overall structure schematic diagrames of the present utility model.
Number in the figure illustrates:
1, workbench; 2, column; 3, slide block; 401, oil cylinder I; 402, oil cylinder II; 403, oil cylinder III.
Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment, the utility model is described in detail.
Embodiment 1
As shown in Figure 1, design the bender of a kind of 3000T, it comprises workbench 1 and slide block 3, also comprise oil cylinder I 401, oil cylinder II 402, oil cylinder III 403 and column 2, in two common cylinder benders, the oil cylinder of needs is 1500T, in the utility model, only need use 1000T oil cylinder, the weight and volume of oil cylinder reduces greatly, and convenient when transporting and install.Described slide block 3 weight also can be reduced to original 2/3rds accordingly, for the frame of Integral bending machine, due to the oil cylinder that originally required and slide block 3 weight large, the support force required is large, so its frame steel plate is thick is generally 240mm-260mm, the utility model only needs to use the thickness of slab between 200mm-220mm can reach the requirement of required support force.Overall frame quality reduces.Its machining accuracy that can maintain more is increased.Especially for the processing of the overweight workpiece of ultra-wide of more than 10m, the precision of necessary requirement can better ensure.
Described column 2 has 3, and become 3 strong points from the original strong point to overall top from 2, the strong point increases, and the more difficult distortion of parts, machining accuracy can better ensure.Be arranged at below oil cylinder I 401, oil cylinder II 402 and oil cylinder III 403 respectively, connecting working table 1 and 3 oil cylinders; Piston rod and the slide block 3 of described oil cylinder I 401, oil cylinder II 402 and oil cylinder III 403 are bolted to connection; Oil cylinder I 401, oil cylinder II 402 are connected by synchronizing shaft with oil cylinder III 403.Make three oil cylinders to carry out synchronously upper and lower motion, ensure that the synchronous of motion and accuracy.Described slide block 3 is connected by the frame of rolling guide bender, slide block 3 is fixed with upper die of bending machine, described workbench 1 is fixed with bender lower die.
Embodiment 2
A kind of bender described in embodiment 2, substantially the same manner as Example 1, difference is, described slide block 3 is connected with the frame of bender by rail plate.
Embodiment 3
A kind of bender described in embodiment 2, for a kind of 4 cylinder benders, its structure is substantially identical with the structure described by embodiment 1, difference is, oil cylinder and column can be 4, and now oil cylinder is 750T oil cylinder, thickness of slab required for it is 160-180mm, the quality of slide block is reduced to the half of two cylinder slider of bender quality, has the more strong point, the more light body of lathe.In like manner can make 5 cylinder benders or 6 cylinder benders, the quantity of its oil cylinder and column increases successively, and the tonnage of oil cylinder progressively reduces, the also reduction progressively of required thickness of slab.Light body can be carried out required for basis gradually.
Below be schematically described the invention and embodiment thereof, this description does not have restricted, and one of embodiment of the also just the invention shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from this creation aim, designing the frame mode similar to this technical scheme and embodiment without creationary, the protection domain of this patent all should be belonged to.
