Abstract
The utility model discloses an upper-cross-beam deflection compensation device of a four-roll veneer reeling machine. The upper-cross-beam deflection compensation device comprises an upper cross beam, a groove is formed in the middle of the upper cross beam, the groove is parallel to the length direction of the upper cross beam, at least one hydraulic oil cylinder is installed inside the groove, and a piston rod of the hydraulic oil cylinder abuts against the bottom of the groove. By means of the upper-cross-beam deflection compensation device, deflection compensation can be conducted for the four-roll veneer reeling machine which is large in board width, barrel-shaped workpieces can be reeled, the fact an upper roll is basically in a straight line state is guaranteed during normal working, and the structure is simple and efficient.
Description
Technical field
The utility model relates to a kind of veneer reeling machine compensation arrangement, relates in particular to a kind of four-roll plate bending machine entablature flexibility compensating device.
Background technology
At present, the large-scale veneer reeling machine of each manufacturer production generally all has the entablature device, but because the plate width that rolls is large, and top roll fulcrum span is large, and top roll generally is elongated, and poor rigidity, so deflection deformation also can become greatly, workpiece rolls precision and is difficult for guaranteeing.Because top roll is subject to power upwards, entablature also can produce distortion, can not guarantee that top roll when normal operation, is in linear state substantially.
Summary of the invention
The entablature of the existing large-scale veneer reeling machine of the technical problems to be solved in the utility model can not guarantee substantially to be in linear state when normal operation under the active force of top roll.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of four-roll plate bending machine entablature flexibility compensating device, comprise entablature, groove is established at described entablature middle part, groove is parallel to the crossbeam length direction, a hydraulic jack is set in the groove at least, and the piston rod of hydraulic jack props up the bottom of groove.
By the drafts of regulator solution compressing cylinder respectively, make entablature be in advance the reversible deformation state, this distortion entablature distortion and top roll flexural deformation of causing when offsetting work.
For ease of the drafts of regulator solution compressing cylinder, described hydraulic jack evenly is arranged in the groove.
Advantage of the present utility model: can carry out deflection compensation to the veneer reeling machine of the wide length of plate, can the bending cylindrical workpiece, when normal operation, guarantee that top roll is in linear state substantially, and simple in structure effectively.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model comprises entablature 1, hydraulic jack 3, and described entablature 1 is fixed on the frame of the left and right sides, and groove 2 is established at entablature middle part from left to right, and groove 2 is interior evenly to arrange seven hydraulic jacks 3.
During use, the piston rod of hydraulic jack 3 is against downwards in the groove 2, applies downward power for groove 2; Regulate respectively the drafts of oil cylinder 3, make entablature 1 be in advance the reversible deformation state, this distortion entablature 1 distortion and top roll flexural deformation of causing when offsetting work.
Claims (2)
