Abstract
The present invention relates to a plate rolling machine for rolling a long cylinder with a small diameter, which comprises a chassis, a machine frame and a working roll arranged on the machine frame. The present invention is characterized in that a supporting device arranged on a base or the chassis is positioned at the middle part of the working roll and is vertical to the working roll, an upper supporting roll with a lifting device is arranged on the supporting device, and the upper supporting roll is positioned above an upper roll. The present invention strengthens the strength and the rigidity of the upper roll when a plate end is preflexed, and does not affect the feeding and the charging of workpieces and the circle rolling process of workpieces with major diameters. The present invention is easy to operate by workers, and improves machine process capability.
Description
The present invention relates to a kind of veneer reeling machine that rolls the small diameter long cylinder.
In the existing veneer reeling machine that rolls the small diameter long cylinder, because the diameter of top roll must be less than processed drum diameter, its size is restricted, and top roll duty factor volume bowlder is many greatly when the pre-bending of the process of rolling, therefore top roll is difficult to reach the requirement of strength and stiffness, the product precision is reduced, and machine capability descends.
In order to address this problem, prior art is that setting is fixed on backbar and backing roll on the frame to top roll, make veneer reeling machine can only roll non-full circle workpiece, perhaps pre-bent plate end on equipment such as forcing press, volume circle, set round on another veneer reeling machine perhaps apply reverse supporting force in the outside, two ends of top roll then, make workman's complicated operation, reduced work efficiency, increased extra load to machine.
WO85/05297 discloses a kind of former of minor diameter pipe, and its backing roll can lifting.But it is because its support that carries backing roll is parallel with home roll, thereby oversize; Support is installed on the frame, and the downforce of backing roll is superimposed upon on the oil cylinder that drives home roll, and the load of frame and home roll oil cylinder is strengthened, and cost rises.
The purpose of this invention is to provide a kind of veneer reeling machine that rolls the small diameter long cylinder, can strengthen the strength and stiffness of top roll when pre-bending, make the product precision higher, the pre-bending steel plate is thicker, makes things convenient for the workman to operate, and reduces equipment manufacturing cost.
The solution of the present invention is: comprise chassis, frame, be arranged at the working roll on the frame, be provided with the top backing up roll of lowering or hoisting gear on the supporting arrangement, this top backing up roll is positioned at the top of top roll, and the supporting arrangement that it is characterized in that being fixed on basis or the chassis is positioned at working roll middle part and vertical with working roll.
When rolling the pre-bent plate end operation of small diameter long cylindrical workpieces, because top backing up roll is positioned at the top, middle part of top roll, can when top roll is stressed, apply downward pressure to it, strengthen its strength and stiffness.The present invention is arranged at liftable top backing up roll on the supporting arrangement, the top roll strength and stiffness are strengthened when making pre-bent plate end, do not influence the workpiece input and output material, again applicable to the processing of the thick tube wall cylinder of minor diameter, and make the workman easy to operate, improved machinery processing capacity, frame is stressed little, and equipment manufacturing cost descends.
Fig. 1 is an embodiment of the invention left view.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3, Fig. 4, Fig. 5, Fig. 6 are the working state schematic representation of the embodiment of the invention.
As shown in Figure 1, comprise chassis 9, frame 10 and be arranged at working roll on the frame, working roll comprises that top roll 7, lower roll 8, side roller 5, guide rail 6 are arranged on the basis 11, and supporting arrangement 1 can move along guide rail, and the top backing up roll 2 that has a lowering or hoisting gear is located on the supporting arrangement and is positioned at the top of top roll.Supporting arrangement can move along guide rail, can make things convenient for the input and output material of workpiece, and can remove supporting arrangement when rolling large diameter cylinder and thin-wall workpiece, has increased the function of equipment and easy to operate.Shown in Fig. 1, can be positioned at the working roll both sides to the afterburning roller 4,12 that applies horizontal force in the middle part of the workpiece, wherein 4 for being arranged on the afterburning roller on basis or the chassis, and 12 for being arranged on the afterburning roller on the supporting arrangement, can move with supporting arrangement.The effect of afterburning roller is when pre-bending, welding, set round afterburning to the workpiece middle part, and the load that can alleviate working roll helps to reduce the plate splaying.3 is workpiece among the figure.
If supporting arrangement is directly fixed on basis or the chassis, applicable to the veneer reeling machine of simple processing small diameter long cylinder or the occasion of minor diameter thick cyclinder.
The top backing up roll head and the tail are adjacent among Fig. 2, interlock and depart from central distribution, can allow pre-bent-up end longer, and can bear certain horizontal force.
Supporting arrangement is not worked among Fig. 3, Fig. 4 is the position of supporting arrangement during for pre-bending of small diameter long cylindrical workpieces or set round, the operating position of supporting arrangement when Fig. 5 represents to roll the major diameter short tube, the operating position when Fig. 6 makes forcing press for supporting arrangement and top backing up roll.Supporting arrangement quantity among the figure is two, and its effect is: for the processing of short cylinder, mobile supporting arrangement is located at the workpiece two ends, can reduce the frame span, improves the strength and stiffness of top roll, and makes the not restriction of supported device of processing work diameter.
Fig. 6 middle guide extends to outside the frame, makes supporting arrangement can be moved to machine and does the forcing press use outward separately.
Claims (4)
1, a kind of veneer reeling machine that rolls the small diameter long cylinder, comprise chassis, frame and be arranged at working roll on the frame, be provided with the top backing up roll of lowering or hoisting gear on the supporting arrangement, this top backing up roll is positioned at the top of top roll, and the supporting arrangement that it is characterized in that being fixed on basis or the chassis is positioned at working roll middle part and vertical with working roll.
