Detailed description of the invention
Refer to shown in Figure of description 1 to accompanying drawing 6, the present invention is a kind of high waveform steel floor support plate cold-bending forming machine, and it is made up of a few parts such as automatic driven unwind machine 1, frame 2, guider 3, lubricating arrangement 4, cold roll forming roll stacks 6, hydraulic cutting device 5 and stacking machines 7.
Wherein, described automatic driven unwind machine 1 is positioned at the side of frame 2, and described stacking machine 7 is positioned at the opposite side of frame 2.Described automatic driven unwind machine 1 is provided with a tubular coiled strip 8, tubular coiled strip 8 launches by this automatic driven unwind machine 1, and realized continuously by the electrical control of automatic driven unwind machine 1 or be interrupted, fast or at a slow speed feed.And described stacking machine 7 pairs of finished products carry out stacking, and send machine.
Described frame 2 is provided with described guider 3, lubricating arrangement 4, cold roll forming roll stacks 6 and hydraulic cutting device 5 successively.Wherein, described guider 3 is positioned at the side of automatic driven unwind machine 1, and when raw material plate is by guider 3, carry out correcting by guider 3 pairs of sheet material left and right sides, it is accurate to guarantee into Board position.Goods after described hydraulic cutting device 5 pairs of cold roll formings cut off, and make different length on request, by the length of electric-control system and control program nonstick system of control product.
Further, described lubricating arrangement 4 comprises a few part composition such as upper shell 41, lower house 42, fog-spray nozzle 43, material storage tube 44 and compression pump 45.Wherein, described upper shell 41 and lower house 42 match, and it are separately installed with described fog-spray nozzle 43.Described fog-spray nozzle 43 is connected with compression pump 45.Described material storage tube 44 one end is connected to the bottom of lower house 42, and the other end is connected with compression pump 45.Form a sheet path 16 between described upper shell 41, lower house 42, in described sheet path 46, be provided with two groups of scraper plates 47.Described scraper plate 47 is specially felt scraper plate 47.
The operation principle of described lubricating arrangement 4 is as follows: lubricating fluid is sent into fog-spray nozzle 43 by compression pump 45 by the road, and lubricating fluid atomization is also sprayed at the upper and lower surface of goods sheet material by fog-spray nozzle 43 equably.Lubricating fluid can be smeared evenly by described scraper plate 47.Lower house 42 can be collected fog-spray nozzle 43 and spray unnecessary lubricating fluid, flow back in storage vat 44 by the road, for recycling.Goods sheet material surface sprinkling lubricating fluid, can reduce the frictional force of roll and goods plate surface greatly, effectively alleviates the injury of roller surface to goods sheet material face coat or coating.
Described cold roll forming roll stacks 6 comprises some roads roll 60, the arrangement in non-equidistance between described roll 60.As shown in Figure of description 3, passage 1 is P1 with the roll shop building distance of passage 2; Passage 2 is P2 with the roll shop building distance of passage 3; By that analogy, passage (n-1) is P (n-1) with the roll shop building distance of passage n.P1, P2 ... P (n-1) is all unequal.The configuration of these different roll shop building distances, the line that can realize single voxel A, B, C, D, E is a straight line.The collocation method of these different roll shop building distances is: 1, first select first road roll shop building apart from P1 according to machine construction and cold roll forming experience; 2, the section half wide cut y1, y2(y1 and y2 that draw according to the design of goods cross section deformation passage be by first roll and the second roll after half wide cut size of goods section), and calculate tangent value tan β=(the y1-y2)/P1 of angle of throat β.3, calculate each road roll shop building apart from Pi=[yi-y (i-1)] tan β, wherein, yi is half wide cut size of the goods section after i-th roll.
Described each roll 60 comprises topping roll group 61, and and the bottom roll group 62 that is oppositely arranged of topping roll group 61.Wherein, described topping roll group 61 to comprise on some large rolls 611, a roll shaft 613 on little roll 612 and.Described large roll 611 is connected with upper roll shaft 613 by some flat keys 65, and is axially fixed on upper roll shaft 613 by some round nuts 63, makes described large roll 611 and upper roll shaft 613 synchronous revolving.Described little roll 612 is built-in with a pair rolling bearing 64 and is supported on roll shaft 613, and it is axially positioned on upper roll shaft 613 by some spacer rings 66, namely goes up little roll 612 empty set on roll shaft 613, and both can relatively rotate.The roll of different-diameter on same upper roll shaft 613 is so just made to rotate with different rotating speeds.If power inputs from upper roll shaft 613, then aforesaid large roll 611 drives goods sheet material, and aforesaid little roll 612 rotates with goods sheet material, effectively avoids roll to skid and the coating of goods sheet material of swiping or coating on goods sheet material.
Described bottom roll group 62 comprises some lower little rolls 621, once large roll 622 and a lower roller shaft 623.Wherein, described lower little roll 61 is connected with lower roller shaft 623 by some flat keys 65, and is axially fixed on lower roller shaft 623 by some round nuts 63, makes described lower little roll 61 and lower roller shaft 623 synchronous revolving.Described lower large roll 622 is built-in with a pair rolling bearing 64 and is supported on lower roller shaft 623, and it is axially positioned on lower roller shaft 623 by some spacer rings 66, and namely lower large roll 622 empty set is on lower roller shaft 623, and both can relatively rotate.The described principle of the same roll stacks 61, size roll rotates with friction speed, and avoids coating or the coating of scraping goods sheet material.
Further, described little roll 612 is arranged between large roll 611, and itself and lower large roll 622 are oppositely arranged.Described large roll 611 and lower little roll 621 are oppositely arranged.
According to the different requirement of cold roll forming, topping roll group 61 active or bottom roll group 62 active can be set to, also can top and bottom rolls group 61,62 all actives or passive.When top and bottom rolls group 61,62 all initiatively time, by upper roll shaft 613 and lower roller shaft 623 axle head configuration travelling gear, make the upper large roll 611 of topping roll group 61 consistent with lower little roll 621 linear velocity of bottom roll group 62.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
