Description

Automatic turnover machine

A kind of automatic turnover machine is used for the processing that the H type steel production line is produced all kinds of steel profile that maybe need weld, belongs to technical field of metallurgical equipment.

H shaped steel production technology mainly comprises plate cutting, operations such as location assembling, welding, edge of a wing correction, then corresponding on the production line by the blanking cutting equipment, the location mounting equipment, automatic welding device and calibration equipment and configuration respective transmissions roller arrangement, compositions such as turning device.But these equipment all can only be finished function separately.At present such production line, returns in the production line again, so that causes labour intensity big so need the off-line upset because turning device can not merge with transmission roller channel, and production efficiency is low, can not ensure the quality of products.

The purpose of this utility model is to overcome above-mentioned weak point, can carry out the workpiece upset aborning thereby provide a kind of, changes different upset circles, then can be used for the location assembling, welding automatically, the automatic turnover machine of operations such as flange plate correction processing.

The utility model mainly adopts two, and independently turning device and supporting transmission roller channel are formed.By two cover lowering or hoisting gears 3, upset encloses 4 to each turning device respectively, upset workbench 5, and electrical apparatus control system 6 combines.Two cover lowering or hoisting gears 3 are connected by chain with upset workbench 5, and upset workbench 5 and upset circle 4 enclose to lead with the working roller that overturns by upset and be connected, and electrical apparatus control system 6 employing leads link to each other with motor in the lowering or hoisting gear respectively.

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described,

The utility model adopts two independently turning device 1 and supporting transmission roller channel 2 compositions, and each turning device 3 is combined by two cover lowering or hoisting gears 3, upset circle 4, upset workbench 5 and electrical apparatus control system 6 respectively.Two cover lowering or hoisting gears 3 are connected by chain with upset workbench 5 and the wheel of the slide guide up and down guiding of the workbench 5 that overturns connects, and upset workbench 5 is connected with upset roller frictional drive and guiding side guide wheel guiding by the upset circle with upset circle 4.Lowering or hoisting gear 3 is raised to desired height to the upset workbench by lifting motor, so as not to workpiece when upset interfere with transmission roller channel, after rotary movement is finished, the decline of upset workbench.Mainly by lifting motor 7 and first order decelerator 8, second level worm and gear pays 9 to lowering or hoisting gear, and sprocket wheel 10, chain 11, column 12 are formed.Lifting motor 7 is connected with first order decelerator 8 by shaft coupling, first order decelerator 8 is paid 9 upper couplings by shaft coupling with second level decelerator worm and gear and is connected, sprocket wheel 10 is installed in second level worm and gear and pays on 9 worm-wheel shafts by chain 11 and be connected with the workbench that overturns, chain 11 1 ends are contained on the upset workbench 5, counterweight in the other end and the lifting column 12 is connected, lifting motor is controlled by AC converter, to guarantee four lowering or hoisting gear synchronous operations, up and down balance system closes workpiece and transmission roller channel card and throws off.

The upset workbench mainly adopts the upset motor to connect upset roller 17, upset roller 17 is installed on the turning rolls 16, adopt alignment pin and bolt to connect, slide guide wheel 15 is installed down at turning rolls 16 two ends respectively, slide guide wheel 15 is connected with guide way 13 by alignment pin and bolt up and down, and side latch device 14 is connected on the guide way 13.Its upset work stage operation principle drives the part running of starting building of upset circle rotating band for upset driven by motor upset roller.Side shelves wheel support 18, support guide body 13 are housed on the turning rolls 16, and the dress pulley base is connected with lifting column 12 guide rails on the guide way 13, and guide way two is embedded in the upset circle by side shelves wheel, and when the upset circle rotated, side shelves wheel rotated simultaneously, kept the upset circle steadily.

The upset circle is made up of rolling ring 19, locking device 20 and middle guide wheel 24.Locking device 20 is installed on the rolling ring 19, and middle guide wheel 24 is installed in the middle of the rolling ring 19.Locking device 20 comprises locking motor 21, and worm and gear is paid, screw mandrel 22, latch 23, and locking motor 21 is in transmission connection by the belt transmission worm and gear, and screw mandrel 22 is connected with latch 23 by bolt.Locking device 20 drives worm and gears by locking motor 21 and pays, and screw mandrel 22 and latch 23 are locked workpiece, make workpiece in switching process unshift in the middle of guide wheel 24, when workpiece enters the upset circle, play the guiding role and switching process in prevent workpiece slide.The upset that the upset circle is placed in the upset workbench rolls on, and two lateral part wheels are close to the upset circle, finishes the rotation of upset circle by the upset machine operation, and the upset workbench is connected with lowering or hoisting gear by chain, and lifting motor work makes the upset workbench reach desired location.The power transmission roller channel drives workpiece turnover upset circle, and the guiding gear wheel is housed on the roller-way, and work centre and upset circle center are consistent, and is beneficial to workpiece turnover turning device.

Electric control system provides electric power to each driving motor in the tipper, and provides defencive functions such as over-current and-load short circuit interlocking to each motor.Utilize an AC converter to solve the synchronization action of lifting motor and upset motor effectively, and have the starting of in running, slowing down, functions such as accelerated service and correct location.

The utlity model has following advantage, 1, can incorporate well in the production line of welded H girder steel, big Assemble the big location of improving, and welding and the labor productivity of proofreading and correct reduce labor intensity, and fall end production cost, Improve the product quality of H girder steel: 2, in switching process, can make in the upset of the symmetrical upset circle of H beam The heart reduces unbalanced moments, and the upset of band limited location can be in any angle orientation, and is easy to operate, reliable; 3, the scope of application is big, changes to compress cushion block, can adapt to the different range workpiece, if any special workpiece, then Needing to change the upset circle just can adapt to; Solve better each operation and can not well receive problem; 4, adopt Stepless electrical machinery speed governing and advanced AC converter, make each parts action synchronously, safe and reliable to operation; 5, combining form variation can be made up according to Workpiece length.
