The locating mechanism is flexible to move, so that the jamming phenomenon is avoided.
Description
Technical field
The utility model relates to sheet metal strip rewinding and checks unit equipment technical field, particularly relates to a kind of open-head pinch roll roll gap positioner.
Background technology
The open-head pinch roll that current most of rewinding unit is used due to the uncertainty of unit supplied materials coil of strip, need meet the instructions for use of uncoiling and lower uncoiling on unit simultaneously.Open-head pinch roll mainly by frame, on pinch slewing rollers, under pinch the parts such as slewing rollers, roll gap adjusting pad, hydraulic cylinder and transmission device and form, under pinch slewing rollers and be fixed in frame, above pinch slewing rollers by Driven by Hydraulic Cylinder lifting.During unit threading, in Driven by Hydraulic Cylinder, pinch slewing rollers and depress, clamp band feeding forward.During upper uncoiling interlock, above pinch slewing rollers and lift, play slewing rollers effect, the cornerite of band at slewing rollers place is too small and cause herein that tension force is unstable, and strip surface easily produces scuffing; If in order to increase cornerite herein and pinch the lifting travel of slewing rollers on reducing, can cause the irregular open-head pinch roll of taking the lead to be difficult for passing through.
Utility model content
In order to overcome the above problems, the utility model provides open-head pinch roll roll gap detent mechanism a kind of simple in structure, practical, easy to maintenance, to realize unit threading and when interlock, splits the different requirements that head-clamp send roller gap.
The technical solution of the utility model is: a kind of open-head pinch roll roll gap positioner, it is characterized in that: comprise support, cylinder, joint, untie-sell axle, connecting rod and rationed marketing axle, described detent mechanism is positioned at, under pinch between slewing rollers bearing block, and the mode being bolted is installed on the outside of frame, cylinder is rack-mount, joint one end is threaded with cylinder, the other end is connected by untie-sell axle with the drive end of connecting rod, the centre position of connecting rod is connected by rationed marketing axle with support, when cylinder piston rod stretches out, under being positioned at, connecting rod driven end pinches slewing rollers bearing block upper surface center, and connecting rod can swing around rationed marketing axle.
Described cylinder is middle gudgeon formula cylinder.
The thickness of described connecting rod is 10mm, and two ends are circular arc.
The utility model can increase the opening degree of open-head pinch roll, is convenient to threading; During upper uncoiling linkage work, be pressed on connecting rod with above pinching the roll gap adjusting pad that slewing rollers are connected, band increases at the upper cornerite that pinches slewing rollers place, has avoided band to produce herein scuffing; Flexibly, there is not stuck phenomenon in the utility model motion; No matter be upper uncoiling or lower uncoiling, band is all identical at the cornerite at open-head pinch roll place, and open-head pinch roll is all worked by identical mode, finally can realize automatic programming by electrical control.

In figure, 1, hydraulic cylinder; 2, on, pinch slewing rollers bearing block; 3, roll gap adjusting pad; 4, frame; 5, under, pinch slewing rollers bearing block; 6, support; 7, cylinder; 8, joint; 9, untie-sell axle; 10, rationed marketing axle; 11, connecting rod.
The specific embodiment
As shown in Figures 1 and 2, a kind of open-head pinch roll roll gap positioner, it is characterized in that: comprise support 6, cylinder 7, joint 8, untie-sell axle 9, connecting rod 11, rationed marketing axle 10, described detent mechanism is positioned at, under pinch between slewing rollers bearing block, and the mode being bolted is installed on the outside of frame 4, cylinder 7 is arranged on support 6, joint 8 one end are threaded with cylinder 7, the other end is connected by untie-sell axle 9 with the drive end of connecting rod 11, the centre position of connecting rod 11 is connected by rationed marketing axle 10 with support 6, when cylinder 7 piston rods stretch out, under being positioned at, connecting rod 11 driven ends pinch slewing rollers bearing block upper surface center, and connecting rod 11 can swing around rationed marketing axle 10.
Described cylinder 7 is middle gudgeon formula cylinder.
The thickness of described connecting rod 11 is 10mm, and two ends are circular arc.
During unit uncoiling threading, in hydraulic cylinder 1 driving, pinch slewing rollers bearing block 2 and rise to extreme position, then cylinder 7 piston rods are retracted into extreme position, cylinder 7 swings around rationed marketing axle 10 by joint 8 and untie-sell axle 9 drive link 11, the upper surface that pinches slewing rollers bearing block 5 under the driven end edge of connecting rod 11 swings to a side, but under not departing from, pinches the upper surface of slewing rollers bearing block 5.Hydraulic cylinder 1 pinches slewing rollers bearing block 2 on driving again and depresses, now with above pinch roll gap adjusting pad 3 lower ends that slewing rollers bearing block 2 is connected and can be pressed onto down and pinch on slewing rollers bearing block 5, according to thickness of strip, by roll gap adjusting pad 3, adjust the gap between two rollers, make two rollers with suitable pressure clamp taut band material feeding forward.
When unit threading finishes to need coordinated operation, first in hydraulic cylinder 1 driving, pinch slewing rollers bearing block 2 and rise to extreme position, then cylinder 7 piston rods reach extreme position, cylinder 7 swings around rationed marketing axle 10 by joint 8 and untie-sell axle 9 drive link 11, under the other end edge of connecting rod 11, pinch slewing rollers bearing block 5 upper surfaces and swing to centre position, hydraulic cylinder 1 pinches slewing rollers bearing block 2 on driving again and depresses, now with above pinch roll gap adjusting pad 3 lower ends that slewing rollers bearing block 2 is connected and be pressed onto on connecting rod 11, gap between two rollers has increased the thickness of connecting rod 11 during than threading, be 10mm, when this has just increased uncoiling operation on unit significantly, band is at the cornerite at open-head pinch roll place, avoided band scuffing.Connecting rod 11 pinches on slewing rollers bearing block 5 upper surfaces under being positioned at all the time in whole swing process, has avoided stuck phenomenon.After the roll gap detent mechanism of transmission side and fore side swings simultaneously and puts in place, hydraulic cylinder pinches slewing rollers on could driving and depresses, in order to avoid damage equipment.Transmission side is identical with fore side.
The utility model not only can increase the opening degree of open-head pinch roll, is convenient to threading; And during upper uncoiling linkage work, be pressed on connecting rod with above pinching the roll gap adjusting pad that slewing rollers are connected, band increases at the upper cornerite that pinches slewing rollers place, has avoided band to produce herein scuffing.In addition, flexibly, there is not stuck phenomenon in the utility model motion; No matter be upper uncoiling or lower uncoiling, band is all identical at the cornerite at open-head pinch roll place, and open-head pinch roll is all worked by identical mode, finally can realize automatic programming by electrical control.
The parts that the present embodiment does not describe in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
Finally explanation is, the utility model is not restricted to the described embodiments, that in above-described embodiment and description, describes just illustrates principle of the present utility model, do not departing under the prerequisite of principle of the present utility model and scope, various changes and modifications all should be encompassed in the middle of claim scope of the present utility model.
