Abstract
A digital control bender with automatic compensation of deflection, which relates to stamping machine with automatic compensation of deflection. The utility model is composed of bottom work table board and controller. In the middle of work table riser, at least one horizontal through trough is opened, in which deflection compensation device connected to controller is set. During the bending of the digital control bender, middle part of slide block may become concave upward because of machine rigidity or stability. During the pressing down, the hydraulic cylinder in middle through trough of work table can make the through trough make elastic deformation and enable the middle part of work table make upward elastic deformation. Such deformation of bottom work table can balance the deformation of machine slide block, guarantee the precision of processing junction surface and effectively overcome the deflection of processing part.
Description
Technical field
The utility model relates to a kind of press, relates in particular to a kind of press of automatic deflection compensation.
Background technology
At present, because the raising of automaticity, rigidity and intensity at the press body can satisfy under the situation of task, the weight of machinery always designs brief more well more, the application of hydraulic technique, make original big inertia design progressively be eliminated, 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, and in use, the elastic deformation of middle part fovea superior can appear in slide block.Make work piece deflection deformation occur.For example, in numerical control bender, owing to the reason of installation or machinery equipment self rigidity, the uneven phenomenon of work piece bending part occurs, two ends are rolled over deeplyer, and the middle part is because the slide block deformation reason, folding line is more shallow, makes work piece deflection deformation occur, can not meet the requirement of processing.Take to increase machine dimensions if address this problem, strengthen machine rigidity and intensity, obviously can not meet the requirement of modern processing manufacturing industry thereby gain in weight.
Summary of the invention
The utility model provides a kind of automation, can overcome the numerical control bender of slide block distortion to the automatic compensation amount of deflection of bending precision influence.
The numerical control bender of automatic compensation amount of deflection of the present utility model comprises lower table plate, controller, at the middle part of workbench riser, offer at least one horizontally disposed through slot, in this groove, be provided with flexibility compensating device, flexibility compensating device connects controller.
Described flexibility compensating device is a hydraulic cylinder.
The cross section of through slot has the isometric straight flange of two levels, and dual-side is a circular arc, and this circular arc is a major arc.
The numerical control bender of automatic compensation amount of deflection of the present utility model is when bending is worked, because machine rigidity or stability, the distortion to fovea superior can appear in the slide block middle part.When pressing down, the hydraulic cylinder that is located in the through slot of workbench middle part is done trace movement upwards by the controller instruction, and through slot is done strain, makes the workbench middle part produce strain upwards.The distortion of lathe slide block has been offset in this distortion of lower table, has guaranteed the precision of processing faying face, has overcome the amount of deflection of work piece effectively.

Fig. 1 is a structural representation of the present utility model
1 is through slot among the figure, the 2nd, and hydraulic cylinder;
Fig. 2 is the A-A view of Fig. 1
3 is workbench risers among the figure, the 4th, and front side board, the 5th, back side panel.
Fig. 3 is the partial enlarged drawing among Fig. 2
The specific embodiment
Numerical control bender of the present utility model is respectively equipped with front side board 5 and back side panel 4 in the front and back of lower table riser 3 side, at riser 3 and front side board 5 and back side panel 4 middle parts, has offered three through slots 1 equably.The cross section of through slot 1 is, upper and lower limit is a straight flange, and level, and dual-side is an arc, and this arc is a major arc, and this major arc connects straight flange up and down, forms a sealing flute profile.The similar cydariform of the cross sectional shape of through slot 1.
In through slot 1, be horizontally disposed with hydraulic cylinder 2.During the upper and lower mould matched moulds, lower table riser 3 is shored in hydraulic cylinder 2 work in through slot 1, make it that strain take place.General lower table riser 3 adopts foundry goods processing to make; therefore, the utility model is provided with front side board 5 and back side panel 4 respectively in the front and back of lower table riser 3, and this two plate adopts steel plate; when deflection is excessive, can effectively protect lower table riser 3 not rupture.
The major arc design of through slot 1 dual-side stays the certain structure space to strain, makes that the stress that deforms can be too unconcentrated.
