Detailed Description

With reference to fig. 1-3, the utility model discloses a divide material to unreel auxiliary stay all-in-one is installed between unreeling equipment and former, including main frame 1, main frame 1 on set gradually along the billet direction of delivery and carry out the leading-in wheel subassembly 2 that leads in with the billet of unreeling machine, carry out the flattening subassembly 3 that flattens and at least two divide strip wheel subassemblies 4 that divide the strip location to carrying the billet to leading-in wheel subassembly 2, at least two divide strip wheel subassemblies 4 between be equipped with the layering wheel subassembly 5 that the billet that passes through that pushes down dispels rebound stress; and a supporting wheel assembly 6 for supporting the rotating shaft of the unreeling machine is arranged on the side of the main frame.

When in processing, the steel bar is unreeled by an unreeling machine, the steel bar enters a flattening assembly after passing through the upper surface of a lead-in wheel, the flattening assembly is provided with a gap a for the steel bar to pass through, the height of the gap a is slightly larger than the thickness of the steel bar, the steel bar enters the gap a or is extruded in the vertical direction and passes through the flattening assembly in the extrusion process due to the limitation of the upper and lower height of the gap a, so the steel bar which is greatly bent receives one-time flattening processing, the bending degree of the steel bar which is subjected to the one-time flattening processing is greatly reduced, the steel bar continuously proceeds to a bar splitting wheel assembly 4, the bar splitting wheel assembly 4 separates the steel bar for two times, a plurality of parallel steel bars which enter subsequent forming equipment keep respective running paths without mutual interference, in the process, the pressing wheel assembly 5 presses the steel bar with small amplitude to slightly bend the steel bar in the opposite direction of the original radian, and further eliminates the resilience stress of the steel bar, so that the steel bar output from the last sub-trolley assembly is kept in a straight state and does not rebound. Meanwhile, in the working process of the unreeling machine, the supporting wheel assembly supports the free end of the rotating shaft of the unreeling machine, so that the supporting wheel assembly is ensured to be in a horizontal state, the abrasion to the bearing at the transmission end is reduced, and the supporting wheel assembly can run stably.

In order to reasonably arrange the components, the main frame 1 is provided with a stepped upper surface 11 descending step by step, and the guide-in wheel component, the flattening component, the slitting wheel component and the pressing strip wheel component are arranged on a multistage step plane at one time.

In the concrete structure of the subassembly that flattens, in order to adapt to the needs of passing through of the billet of different thickness, give corresponding suppression scope simultaneously, in this embodiment, the subassembly 3 that flattens include two collateral branch framves 31 of fixing in base upper surface both sides, every collateral branch frame 31 includes two stands 311 and the crossbeam 312 that is located two stand tops respectively, the bottom is equipped with one and fixes whole flat 32 seats on the base upper surface between two collateral branch framves 31, be equipped with the briquetting 33 that a size and flattening base suited and liftable directly over the flattening base 32, be provided with a cylinder 34 on the crossbeam 312 of every collateral branch frame respectively, the telescopic link of cylinder 34 passes crossbeam 312 and is connected with the corresponding one end of briquetting 33.

The cylinder can be lifted through the action of the cylinder 34 before processing, the height of the gap a is increased, the front end of the steel bar passes through smoothly, and then the height of the gap a is gradually reduced when the height of the pressing block 33 is reduced, so that the steel bar a can be just accommodated to pass through.

The strip separating wheel assembly 4 is intended to limit the traveling route of the steel strip passing through the flattening assembly 3, since a plurality of parallel steel strips driven by the uncoiler are not constrained when passing through the flattening assembly 3, and the steel strip easily deviates when the driving force of the uncoiler is driven and the gap a is vertically pressed, in this embodiment, the strip separating wheel assembly 4 includes two side supporting plates 41 with two sides fixed on the step plane of the main support and a strip separating wheel 42 positioned between the two side supporting plates 41, and the strip separating wheel 42 is provided with a partition plate 43 for separating the steel strip. Each strip passes through the space between the different partitions while passing through the slitting wheel 42, thereby correcting the running direction.

After the primary pressing of the flattening assembly 3, although the radian of the steel bar is greatly reduced, due to the hardness and toughness of the steel bar, small-amplitude resilience still exists after the steel bar is out of constraint, so that secondary pressing needs to be performed through the pressing strip wheel assembly 5 to eliminate the resilience stress of the steel bar, in the embodiment, the pressing strip wheel assembly 5 comprises two side mounting plates 51 with two sides fixed on the step plane of the main support 1 and a lifting pinch roller 52 positioned on the two side mounting plates 51, each side mounting plate 51 is provided with a pressing strip cylinder 53, and the telescopic rod of each pressing strip cylinder 53 is connected with the lifting pinch roller 52 and drives the lifting pinch roller 52 to lift. When the liftable pinch roller 52 is pressed down, the lowest height of the descending is lower than the height of the upper tangent line of the two sub-strip wheel assemblies 4, even if the steel belt is bent downwards in a small range by the 4-position end points of the two sub-strip wheel assemblies, so that the resilience force of the steel belt is eliminated.

Because the supporting wheel subassembly both will realize the support to the unreeling machine pivot, will dodge when rolling up from top to bottom again, conveniently roll up from top to bottom the operation, so in this embodiment supporting wheel subassembly 6 include one install in the base 61 on ground and with the fixed collateral branch brace 62 in main support side, the tip of collateral branch brace 62 through a pivot swing joint cylinder 63, the telescopic link tip of cylinder 63 supports swing arm 64 through a pivot swing joint, supports swing arm 65 simultaneously and installs on base 61 through perpendicular pivot, is equipped with horizontal riding wheel 65 and the vertical riding wheel 66 of bearing unreeling machine pivot on the support swing arm 64. The operation of rolling up and down is, the cylinder 63 contracts, support the swing arm 65 and be pulled back, keep away from the pivot of unreeling machine, can normally carry out the operation of rolling up and down this moment, after the completion of rolling up, strut the cylinder, support a swing arm base and rotate for the prototype, make horizontal riding wheel 65 and vertical riding wheel 66 contact the pivot of unreeling machine, can realize supporting, wherein horizontal riding wheel 65 mainly is responsible for bearing the heavy burden of unreeling machine pivot perpendicularly, vertical riding wheel 66 mainly is spacing to the horizontal direction memorability of unreeling machine, simultaneously with the rotation synchronization of unreeling machine pivot.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
