Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The high frequency welding pipe molding roll device that bending radius is as shown in Figure 1 adjustable, is comprised roller bracket 1, is installed in rotation on the side roll supporting seat 2 of the left and right sides below roller bracket 1 by axle 6, the side roll 3 that can be arranged on axially slidably in side roll supporting seat 2, is positioned at left and right two in the middle of side roll supporting seats 2 and along roller bracket 1 straight roller supporting seat 20 and be arranged on the straight roller 4 of straight roller supporting seat 20 axially slidably; The straight roller axis 12 of straight roller 4 overlaps with the roller bracket axis 10 of roller bracket 1, and the side roll axis 11 of two side rolls 3 intersects at a point with the straight roller axis 12 of straight roller 4, and two side roll 3 centers are identical to the distance of intersection point with straight roller 4 center to the distance of intersection point.
Shown in composition graphs 2, the gripper shoe 13 that the roller bracket 1 of the present embodiment comprises the front and back fixed head 1.2 be arranged in parallel, the header board 1.1 being fixedly connected with front and back fixed head 1.2 and is positioned at above straight roller supporting seat 20.Fixed head 1.2 left and right sides, front and back all has the axis hole 1.3 matched with the axle 6 of side roll supporting seat 2 two sides; The centre position of front and back fixed head 1.2 has the chute 1.4 slided for straight roller supporting seat 20.
Shown in composition graphs 3,4, left and right two side roll supporting seats 2 are all provided with a tooth bar 7, and two tooth bars 7 engage each other, regulate screw mandrel 8 to drive one of them tooth bar 7 to rotate, two side roll supporting seats 2 can synchronously be rotated around axle 6 by tooth bar 7, thus change the roll surface direction of side roll 3; Side roll supporting seat 2 upper surface has the screwed hole through side roll adjustment screw mandrel 5, side roll 3 is arranged on side roll seat 15 by side roll roll shaft 14, in the present embodiment, the external diameter of side roll seat 15 is identical with the internal diameter of side roll supporting seat 2, the end of side roll adjustment screw mandrel 5 is connected with side roll seat 15, by regulating side roll adjustment screw mandrel 5, drive the upper and lower adjustment of side roll 3 in side roll seat 15.Shown in composition graphs 5, the gripper shoe 13 of roller bracket 1 has the screwed hole through straight roller adjustment screw mandrel 9, the end of straight roller adjustment screw mandrel 9 is connected with straight roller supporting seat 20.By regulating straight roller to adjust screw mandrel 9, the straight roller 4 in straight roller supporting seat 20 is driven to carry out upper and lower adjustment.Like this can by the position of adjustment two side rolls 3 and a straight roller 2, the bending radius that just can realize whole roll device within the specific limits changes, thus carries out bending in various degree to rolled piece.
Concrete adjustment process is as follows: as shown in Figure 6,7
A) the high frequency welding pipe molding roll device that bending radius is adjustable is lower adjustment on the whole: as shown in Figure 3, upper roller slide block 17 is driven to move up and down by the down screw rod of top roll, upper roller slide block 17 drives crossbeam 16 and the roller bracket 1 that connects with it to move up and down, thus drives the upper and lower adjustment of whole roll device.
B) adjustment of two side rolls: regulate side roll adjustment screw mandrel 5, make side roll seat 15 carry out upper and lower moving with side roll 3 along the inwall of side roll supporting seat 2; Side roll supporting seat 20 and tooth bar 7 are connected, and when adjusting adjustment screw mandrel 8, the side roll supporting seat 2 regulating screw mandrel 8 to haul one of them tooth bar 7 and this tooth bar 7 correspondence rotates around axle 6, thus realizes the rotation of one of them side roll 3; Meanwhile, one of them tooth bar 7 drives another tooth bar 7 to be rotated around axle 6, thus drives another side roll 3 to rotate around axle 6.
C) adjustment of straight roller: by adjusting straight roller adjustment screw mandrel 9, can drive straight roller supporting seat 20 and straight roller 4 to adjust along chute about 1.4.
The change of roll device Variable-Bend bilge radius: according to the design radial of clod wash pass, through above-mentioned adjustment a), b), c), the roll surface of two side rolls 3 and a straight roller 4 is adjusted on certain bending circular arc, these three rollers coordinate with lower roll thus carry out bending deformation to rolled piece 18, rolled piece 18 can be deformed into rolled piece 19 (as shown in Figure 7).
The high frequency welding pipe molding roll device that the bending radius of the present embodiment is adjustable, it not only can greatly reduce the investment of roll, enhance productivity simultaneously, reduce labor intensity of operating staff, the adjustment of cold roll forming can also be convenient to, improve shaping efficiency and precision, be specially adapted to the production of large-scale petroleum natural gas ratio-frequency welded tube.For
and the welded tube of above specification, about 80 tons, a set of roll of each specification, a set of milling train calculates by 10 cover rolls, amounts to roll preparation amount about 800 tons, roll gross investment about 3,200 ten thousand yuan.If use the high frequency welding pipe molding roll device that the bending radius of the present embodiment is adjustable, often overlap roll and can save roll 30%, a set of milling train can be saved roll and invest 9,600,000 yuan.
