Abstract
The utility model discloses a straightening machine with an overrunning clutch function. The straightening machine comprises a driving roller system and a driven roller system which are arranged in parallel in stagger mode. The straightening machine is characterized in that the driving roller system is driven by a main transmission system, the driven roller system is driven by a driven roller system transmission device through a coupler to rotate, and an overrunning clutch is arranged between the coupler and the driven roller system. The straightening machine can reduce speed difference between the driving roller system and the driven roller system in the meshing process, reduces impact of rolled pieces to a roller ring in the meshing process, effectively prolongs service life of the roller ring and simultaneously effectively improves product quality.
Description
Technical field
The utility model relates to a kind of straightener.
Background technology
Existing straightener is divided into two kinds of independent transmission and non-independent transmissions from type of belt drive.Each roller system of straightener all is called independent type of belt drive straightener by the form of drive power source.Non-independent type of belt drive straightener generally is made up of a row drive roll system (claiming driven roller system again) and row's driven roll system, both the row of going up or down row's smoothing roll system connect power source, all the other rollers systems are by the frictional force rotation of rolled piece in the aligning process and roll.Non-independent type of belt drive straightener causes rolled piece to impact collars because the speed difference that drive roll is and driven roll is in the process of nipping is excessive, has shortened the service life of collars, has also influenced product quality.
The utility model content
The purpose of the utility model is to provide a kind of straightener with the overdrive clutch function.
To achieve these goals; Adopt following technical scheme: a kind of band overdrive clutch function straightener; Comprise the drive roll system and the driven roll system that are staggeredly arranged in parallel; It is characterized in that: drive roll system is driven by main transmission, and driven roll is that transmission device passes through the rotation of shaft coupling driving driven roll system, is provided with freewheel clutch between said shaft coupling and the driven roll system.
For the ease of the axial adjustment of roller system, said drive roll system and driven roll are fastened and are provided with axial adjusting device.
For the ease of adjusting roll gap between master, the driven roll system, be equipped with on the frame of straightener the roll gap adjusting device that can adjust distance between drive roll system and the driven roll system.
Speed difference when the utility model can reduce to nip between drive roll system and the driven roll system, thus rolled piece is to the impact of collars when having reduced to nip, and has effectively prolonged the service life of collars, and the while has effectively been improved product quality.
Description of drawings
Fig. 1 is that straightener roller system arranges sketch map;
The structural representation of Fig. 2 the utility model.
Among the figure, 1 for main transmission, 2 for axial adjusting device, 3 for drive roll system, 4 for the collars assembling, 5 for locking device, 6 for driven roll system, 7 for bearing block, 8 for roll gap adjusting device, 9 be frame, 10 for driven roll be that transmission device, 11 is that shaft coupling, 12 is a freewheel clutch.
The specific embodiment
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
As shown in Figure 2, bearing block 7 is installed in the frame 9, and keeps sliding relatively with frame 9; Drive roll is 3 to be directly installed in the frame 9, and driven roll is 6 to be installed in the bearing block 7.Certainly as a kind of distortion, also driven roll is 6 to be directly installed in the frame 9, and drive roll is 3 to be installed in the bearing block 7.Drive roll is 3 to be connected with main transmission 1, and leaning on the power of main transmission 1 to drive drive roll is 3 to rotate; Driven roll is that transmission device 10 is packed on the bearing block 7, so that when roll gap is adjusted, move with bearing block 7; Driven roll is a transmission device 10 through shaft coupling 11 and freewheel clutch 12 and driven roll is 6 to be connected; But shaft coupling 11 axial stretchings, so as when axial adjustment, to guarantee driven roll be 6 with driven roll be that transmission device 10 is in connection status all the time; Through axial adjusting device 2 can realize drive roll be 3 and driven roll be 6 the collars of installing assembling 4 center line with cross steel wire and align, this function also can realize through installation corresponding function hydraulic mechanism; Collars assembling 4 is roll shaft locking through locking device 5 and each active and passive roller; Roll gap adjusting device 8 links to each other with frame 9 with bearing block 7, drive driven roll and be 6 or drive roll be that 3 vertical direction move, this roll gap adjusting device 8 also has the corresponding function hydraulic mechanism.
During the aligning section bar; Driving main transmission 1 and driven roll simultaneously is transmission device 10, and at this moment, drive roll is 3 under the drive of main rotation system 1, to rotate with certain speed; In this simultaneously, driven roll be transmission device 10 drive driven rolls be 6 with near but the speed that is slightly less than drive roll system rotate.After rolled piece is nipped; Drive roll is 3 drive workpiece motion s, and it is 6 rotations that the effect of frictionally drives driven roll, at this moment; Driven roll is that to increase to drive roll rapidly be that 3 speed is consistent for 6 speed; Therefore driven roll is that 6 speed is transmission mechanism 10 output speeds greater than driven roll the time, and freewheel clutch begins effect, make driven roll be 6 with driven roll be that transmission device 10 is in disengaged position.After treating that aligning is accomplished; Driven roll is that 6 speed slowly reduces; When being reduced to driven roll is that transmission device 10 is when consistent; Leaning on the effect of freewheel clutch to make driven roll be transmission device 10 with driven roll is 6 to keep connection status again, with near but the speed that is slightly less than drive roll system rotate, wait for aligning next time.
Claims (3)
1. be with overdrive clutch function straightener for one kind; Comprise the drive roll system and the driven roll system that are staggeredly arranged in parallel; It is characterized in that: drive roll system is driven by main transmission; Driven roll is that transmission device passes through the rotation of shaft coupling driving driven roll system, is provided with freewheel clutch between said shaft coupling and the driven roll system.
2. band overdrive clutch function straightener as claimed in claim 1 is characterized in that: said drive roll system and driven roll are fastened and are provided with axial adjusting device.
