Abstract
The utility model relates to a device which can adjust the change speed of the roll gap and can roll workpieces with changeable sections; a main hydraulic cylinder is fixed at a rack; a cylinder rod is connected with an upper roller by a beam; a hydraulic profiling valve is fixed at the rack; a lever fulcrum is fixed on the rack; a mold disk is connected with the beam by a bearing; one end of a lever is articulated with the hydraulic profiling valve, while the other end of the lever is articulated with a profiling disk; the mold disk is driven by a motor by a chain wheel and a chain; rotating speed of the motor is controlled by a motor governor; through the rotating of the mold disk, the lever controls the hydraulic profiling valve to lead the cylinder rod of the main hydraulic cylinder to drive the upper roller to move periodically, thereby leading a periodical changing of the roll gap; the changing speed of the roll gap can be controlled through adjusting the rotating speed of the motor by the motor governor.
Description
The utility model is a processing variable cross-section workpiece, and the device as workpiece such as automobile changeable section plate springs belongs to metal rolled technical field.
Present known hydraulic tracing control milling train, the rotating speed of mould disks and the linear velocity of rolled piece are synchronous, and the speed that roll gap changes can not be adjusted.Mould disks can only rolling a kind of slope workpiece.If will change rolling kind, must change mould disks.This makes production efficiency low, the production cost height.
The utility model purpose is to overcome the deficiency of known technology, proposes a kind of hydraulic tracing control rolling device of adjustable roller seam pace of change.With a mould disks can rolling various slopes the variable cross-section workpiece.Enhance productivity, reduce production costs.
The purpose of this utility model is achieved in that wherein main hydraulic cylinder (1) is fixed on the frame (8), crossbeam (2) is connected with last roll bearing seat (14), the imitative type valve (17) of hydraulic pressure is fixed on the frame (8), one end of valve rod and lever (16) is hinged, and two valve ports are connected with (19) two hydraulic fluid ports with main hydraulic cylinder (1) by oil pipe (18) respectively.The fulcrum of lever (16) is fixed on the frame (8), mould disks (15) is connected with crossbeam (2) by bearing, and it is hinged with an end of lever (16), sprocket wheel (12) and coaxial connection of mould disks (15), motor (13) is fixed on the crossbeam (2), sprocket wheel (10) is installed on the output shaft of motor (13), sprocket wheel (10) is connected by chain (11) with sprocket wheel (12), machine governor (6) is electrically connected with motor (13), machine governor (6) can be regulated the rotating speed of motor (13), and then changes the rotating speed of mould disks (15).When mould disks (15) rotation speed change, the movement velocity of the valve rod of hydraulic tracing control valve (17) changes thereupon, and then drives main hydraulic cylinder (1) and drive topping roll the roll gap pace of change is also changed thereupon.
Owing to the employing such scheme, when changing the workpiece slope, do not need to change again mould disks, only need to get final product by the rotating speed of machine governor (6) adjustment motor (13) and then the rotating speed of change mould disks, improved production efficiency, reduced production cost.
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is a structure chart of the present utility model, also is an embodiment:
In Fig. 1, (1) main hydraulic cylinder, (2) crossbeam, (3) topping roll, (4) bottom roll, (5) rolled piece, (6) machine governor, (7) cable, (8) frame, (9) bottom roll bearing block, (10) sprocket wheel, (11) chain, (12) sprocket wheel, (13) motor, (14) go up roll bearing seat, (15) mould disks, (16) reaction lever, (17) hydraulic pressure is imitated type valve, (18) oil pipe, (19) oil pipe, wherein main hydraulic cylinder (1) is fixed on the frame (8), and crossbeam (2) is connected with last roll bearing seat (14), and the imitative type valve (17) of hydraulic pressure is fixed on the frame (8), one end of valve rod and lever (16) is hinged, and two valve ports are connected with (19) two hydraulic fluid ports with main hydraulic cylinder (1) by oil pipe (18) respectively.The fulcrum of lever (16) is fixed on the frame (8), mould disks (15) is connected with crossbeam (2) by bearing, and it is hinged with an end of lever (16), sprocket wheel (12) and coaxial connection of mould disks (15), motor (13) is fixed on the crossbeam (2), sprocket wheel (10) is installed on the output shaft of motor (13), and sprocket wheel (10) is connected by chain (11) with sprocket wheel (12).Machine governor (6) is electrically connected with motor (13).
Embodiment:
Fig. 1 is two roller systems, and bottom roll (4) is installed in the window bottom of frame (8) by bottom roll bearing block (9), topping roll (3) move through main hydraulic cylinder (1) and crossbeam (2) is realized.Mould disks (15) is the discoid pieces of polar coordinates function, when it rotates and the radius value of lever (16) hinged place with variation in angular displacement, motor (13) is by sprocket wheel (10), chain (11), sprocket wheel (12) drives mould disks (15) and rotates, the rotation of mould disks (15) makes the spool of the imitative type valve (17) of hydraulic pressure produce certain displacement by lever (16), controls the hydraulic fluid flow rate of main hydraulic cylinder (1).Make crossbeam (2) and topping roll (3) produce certain displacement, mould disks (15) rotates a week, and topping roll (3) produces cycle movement once.Because the axis of bottom roll (4) is fixed, the roll gap between top and bottom rolls also will produce cyclically-varying.When roll gap is big, workpiece is sent into roll gap.Roll gap hour can be realized the rolling deformation to workpiece (5).Change the rotating speed of motor (13) by machine governor (6), and then pass through sprocket wheel (10), chain (11), sprocket wheel (12) change the pace of change that the speed of imitating the rotation of type dish just can change roll gap.
Compared with prior art, the beneficial effects of the utility model are that it can enhance productivity, and reduce and give birth to Produce cost.
