Abstract

The feature of novel three rolls plate bending machine is, two lower rolls are arranged on one all separately and swing on chunk, and this pedestal swinging chunk is a buckstay, and lower roll and support roller device are all arranged on above buckstay, is swing hinged seat below buckstay.Two lower rolls swing chunk and are arranged on same base all in hinged way, and positional symmetry moves up and down trajectory plane in top roll center line, manipulate it swing with oil cylinder.Two lower rolls can swing arbitrarily, can regulate centre distance each other, and meanwhile two lower rolls obtain again carrying roller support all the time.Novel three rolls plate bending machine both can improve roll bending precision under the prerequisite do not raised the cost, and can improve again roll bending ability and expand the scope of application.

Description

A kind of three rolls plate bending machine
Technical field
The present invention relates to a kind of forging machine tool equipment, especially veneer reeling machine.
Background technology
At present, in known three rolls plate bending machine, a kind of two lower rolls are had to be mounted on same base, position is changeless, its major advantage is, two lower rolls can rely on base to implement carrying roller and support, its rigidity of the lower roll having carrying roller to support is best, can effectively improve roll bending precision and reduce investment outlay, its major defect is two lower roller center distances is fixing dead, centre-to-centre spacing size is non-adjustable, and the veneer reeling machine of this type is domestic to be called " top roller universal veneer reeling machine ", the numerous not concrete example of domestic production producer; A kind of two lower rolls are had to be unfixed, guide rail can move horizontally individually or simultaneously, its major advantage is, two lower roller center distances are adjustable, when centre-to-centre spacing strengthens, onesize pressure of top roll, can roll thicker steel plate, can roll up the circle of small diameter when centre-to-centre spacing reduces, its major defect is, because two lower rolls are unfixed relative to base, carrying roller cannot be obtained and support.This veneer reeling machine is domestic to be called " horizontal downward-adjusting type lapping machine ", and famous brand has " MAV " veneer reeling machine of Italian DAVI company.Lower roll have carrying roller support and lower roller center distance adjustable, this is two extraordinary functions, unfortunately a kind of veneer reeling machine is not had to possess this two functions all over the body, there is adjustable lower roller center distance, but two lower rolls can not get carrying roller and support, two lower rolls can obtain carrying roller and support, but two lower roller center distances are just non-adjustable, the present situation of Here it is countries in the world veneer reeling machine.
Summary of the invention
In order to change the deficiency of the above-mentioned present situation of veneer reeling machine, the present invention proposes a kind of three rolls plate bending machine, and this veneer reeling machine two lower rolls can change centre distance to each other, can obtain again the support of carrying roller all the time.
The technical solution adopted for the present invention to solve the technical problems is: a kind of three rolls plate bending machine, by top roll, lower roll swings chunk, swing hinged seat, swing manipulation oil cylinder, base, left frame, right frame, top roll left end pressurization oil cylinder, top roll right-hand member pressurization oil cylinder, top roll left end overturning bearing body, overturning oil cylinder, top roll right-hand member bearing body, top roll Power Component and lower roll Power Component composition, it is characterized in that: two lower rolls swing chunk and are respectively arranged on base with swing hinged seat, positional symmetry moves up and down trajectory plane in top roll center line, swing chunk with swing manipulation oil cylinder manipulation lower roll to swing, to change the centre-to-centre spacing between two lower rolls, lower roll swings chunk by lower roll, lower roll left end shaft bearing, lower roll right-hand member bearing block, buckstay, support roller device, swings hinged support part and oil cylinder Connection Block composition, lower roll is fixed on buckstay upper surface by lower roll left end shaft bearing and lower roll right-hand member bearing block, support roller device is arranged in the middle of buckstay upper surface lower roll left end shaft bearing and lower roll right-hand member bearing block, swings hinged support part and is fixed on buckstay lower surface.
The invention has the beneficial effects as follows, two lower rolls can swing arbitrarily the centre distance regulated each other, and two lower rolls can obtain carrying roller all the time and support.Three rolls plate bending machine both can improve a roll bending precision under the prerequisite do not raised the cost, and can improve again roll bending ability and expand the scope of application.

Detailed description of the invention
In Fig. 1 embodiment, lower roll swings chunk (5) swing hinged seat (13) and is arranged on base (12).Lower roll swings chunk and left frame (2) and right frame (11) and keeps certain free gap, with the swing not hindering lower roll to swing chunk.Top roll right-hand member pressurization oil cylinder (7) drives top roll right-hand member bearing body (8) to move up and down at right frame (11) slideway place.Top roll left end pressurization oil cylinder (1) to be connected in hinged way with top roll left end overturning bearing body (4) by its piston rod earrings (15) and to drive it to move up and down at left frame (2) slideway place.Top roll left end overturning bearing body (4) can by the jointed shaft overturning 90 ° shared with cylinder piston rod earrings.Select top roll to drive as required, or lower roll drives, or up-down rollers all drive.
In Fig. 2 embodiment, two oil cylinder Connection Blocks (25) can be fixed on buckstay (22), position can at lower roll right-hand member bearing block (21), in the middle of the neutral gear of support roller device (23) and lower roll left end shaft bearing (26).Below buckstay, three swing the position of hinged support part (27), are preferably aligned in the lower roll right-hand member bearing block (21) that buckstay is installed respectively above, support roller device (23) and lower roll left end shaft bearing (26).Buckstay cross sectional shape can the side of being, can be also other shape, as long as have enough torsional rigidities and local compressive resistance both can.
