Abstract
The utility model discloses a multi-cylinder bending machine. The multi-cylinder bending machine comprises a workbench which fixes a lower die; two ends of the workbench are provided with operating cylinders; an upper sliding block which is used for fixing an upper die is arranged between the workbench and the operating cylinders; the middle of the upper sliding block is provided with a plurality of middle compensating cylinders; the number of the middle compensating cylinders varies along with the length change of the upper sliding block; the middle compensating cylinders are provided with size compensating adjusting devices to enable size adjustment through users to be convenient. When the novel bending machine performs bending work, upward concave deformation exists in the middle of the upper sliding block due to the machine rigidity or stability. When the upper sliding block press downward, the middle compensating oil cylinders can compensate the concave deformation of the upper sliding block, and accordingly the machining accuracy of a junction surface is guaranteed and the problem that the middle folding mark is shallow and two end folding marks are deep in a machined workpiece is solved.
Description
Technical field
The utility model relates to a kind of hydraulic machinery, relates in particular to a kind of multi-cylinder bender that can compensate amount of deflection.
Background technology
At present, raising due to automaticity, in the situation that the Rigidity and strength of hydraulic machinery body can meet task, the weight of machinery always designs more brief better, the application of hydraulic technique, original large inertia design is progressively eliminated, and machine construction is more and more lighter and handier, and this has greatly reduced the cost of machine.But this has also brought some technical problems, in use, slide block there will be the strain of middle part fovea superior, makes work piece occur deflection deformation., owing to installing or the rigidity reason of machinery equipment self, there is work piece bending part angle, the inhomogeneous phenomenon of linearity in bender for example, two ends are rolled over deeplyer, and middle part is because slide block is out of shape, and folding line is more shallow, make work piece occur deflection deformation, can not meet the requirement of processing.If addressed this problem, take to increase machine dimensions, thereby gain in weight strengthening machine Rigidity and strength, requirement that obviously can not the modern processing manufacturing industry of symbol.
Utility model content
The technical problems to be solved in the utility model is the defect that overcomes prior art, provides a kind of and can overcome top shoe distortion, affects the multi-cylinder bender of bending precision.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of multi-cylinder bender of the utility model, comprise the fixedly workbench of counterdie, described workbench two ends are provided with operating cylinder, between described workbench and described operating cylinder, be provided with for the fixing top shoe of patrix, described top shoe middle part is provided with some middle parts compensating cylinder, and the quantity of middle part compensating cylinder changes with the variation of top shoe length.
Further, in order to facilitate user to adjust compensation size, described middle part compensating cylinder is provided with compensation size adjusting device.
Bender of the present utility model is when bending is worked, when top shoe presses down, middle part compensating cylinder can make up the spill distortion of top shoe, thereby has guaranteed the precision of processing faying face, effectively overcome work piece and occurred that middle part folding line is shallow, the problem that two ends folding line is dark.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model with embodiment mono-of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of multi-cylinder bender of the utility model, comprise the fixedly workbench 1 of counterdie, described workbench 1 two ends are provided with operating cylinder 2, between described workbench 1 and described operating cylinder 2, be provided with for the fixing top shoe 3 of patrix, described top shoe 3 middle parts are provided with some middle parts compensating cylinder 4, and the quantity of middle part compensating cylinder 4 changes with the variation of top shoe 3 length.
In addition,, in order to facilitate user to adjust, middle part of the present utility model compensating cylinder 4 is provided with compensation size adjusting device 5.
During bending work, top shoe 3 presses down with operating cylinder 2, when top shoe 3 plays Y1 because rigid deformation is middle to fovea superior, middle part compensating cylinder 4 applies downward pressure Y2, effectively make up the distortion of top shoe 3, thereby guaranteed the precision of processing faying face, effectively overcome work piece and occurred that middle part folding line is shallow, the problem that two ends folding line is dark.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
