Description
Technical field
The present invention relates to sheet metal strip rewinding and check unit equipment technical field, particularly relate to a kind of open-head pinch roll roll gap detent mechanism.
Background technology
The open-head pinch roll that current most of rewinding unit uses, 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 primarily of frame, on pinch slewing rollers, under pinch the parts such as slewing rollers, roll gap regulation pad, hydraulic cylinder and transmission device composition, under pinch slewing rollers and be fixed in frame, above pinch slewing rollers and be elevated by Driven by Hydraulic Cylinder.During unit threading, Driven by Hydraulic Cylinder pinches slewing rollers pressure, the feeding forward of clamping band.During upper uncoiling interlock, above pinch slewing rollers and lift, play slewing rollers effect, band is too small and cause tension force instability herein at the cornerite at slewing rollers place, and strip surface easily produces scuffing; If in order to increase cornerite herein and pinch the lifting travel of slewing rollers on reducing, then irregular taking the lead can be caused to not easily pass through open-head pinch roll.
Summary of the invention
In order to overcome the above problems, the invention provides a kind of structure simple, practical, open-head pinch roll roll gap detent mechanism easy to maintenance, during to realize unit threading and interlock, split the different requirements that head-clamp send roller gap.
Technical scheme of the present invention is: a kind of open-head pinch roll roll gap detent mechanism, 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 be bolted is installed on the outside of frame, cylinder is rack-mount, joint one end is threaded with cylinder, the drive end of the other end and connecting rod is by dynamic pinned connection, the centre position of connecting rod and support are by determining pinned connection, when cylinder piston rod stretches out, slewing rollers bearing block upper surface center is pinched under connecting rod driven end is positioned at, and connecting rod can swing around rationed marketing axle.
Described cylinder is middle trunnion type cylinder.
The thickness of described connecting rod is 10mm, and two ends are circular arc.
The present invention can increase the opening degree of open-head pinch roll, is convenient to threading; During upper uncoiling linkage work, and above pinch the roll gap regulation pad that slewing rollers are connected and be pressed on connecting rod, band increases at the upper cornerite pinching slewing rollers place, avoids band and produces scuffing herein; The present invention's campaign is flexible, there is not stuck phenomenon; No matter be upper uncoiling or lower uncoiling, the cornerite of band at open-head pinch roll place is all identical, and open-head pinch roll all works by identical mode, finally realizes automatic programming by electrical control.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.
In figure, 1, hydraulic cylinder; 2, slewing rollers bearing block is pinched on; 3, roll gap regulation pad; 4, frame; 5, slewing rollers bearing block is pinched under; 6, support; 7, cylinder; 8, joint; 9, untie-sell axle; 10, rationed marketing axle; 11, connecting rod.
Detailed description of the invention
As shown in Figures 1 and 2, a kind of open-head pinch roll roll gap detent mechanism, 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 be bolted is installed on the outside of frame 4, cylinder 7 is installed on the frame 6, joint 8 one end is 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 rod stretches out, slewing rollers bearing block upper surface center is pinched under connecting rod 11 driven end is positioned at, and connecting rod 11 can swing around rationed marketing axle 10.
Described cylinder 7 is middle trunnion type cylinder.
The thickness of described connecting rod 11 is 10mm, and two ends are circular arc.
During unit uncoiling threading, hydraulic cylinder 1 pinches slewing rollers bearing block 2 on driving and rises to extreme position, then cylinder 7 piston rod is retracted into extreme position, cylinder 7 is swung around rationed marketing axle 10 by joint 8 and untie-sell axle 9 drive link 11, the upper surface pinching slewing rollers bearing block 5 under the driven end edge of connecting rod 11 swings to side, but pinches the upper surface of slewing rollers bearing block 5 under not departing from.Hydraulic cylinder 1 pinches slewing rollers bearing block 2 on driving again and depresses, now with above pinch roll gap regulation pad 3 lower end that slewing rollers bearing block 2 is connected and can be pressed onto down and pinch on slewing rollers bearing block 5, adjust gap between two rollers according to thickness of strip by roll gap regulation pad 3, make two rollers with suitable pressure clamp taut band material feeding forward.
When unit threading terminates to need coordinated operation, first hydraulic cylinder 1 pinches slewing rollers bearing block 2 on driving and rises to extreme position, then cylinder 7 piston rod reaches extreme position, cylinder 7 is swung around rationed marketing axle 10 by joint 8 and untie-sell axle 9 drive link 11, pinch slewing rollers bearing block 5 upper surface under the other end edge of connecting rod 11 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 regulation pad 3 lower end that slewing rollers bearing block 2 is connected and be pressed onto on connecting rod 11, gap between two rollers is than the thickness adding connecting rod 11 during threading, i.e. 10mm, this just to considerably increase on unit the cornerite of band at open-head pinch roll place when uncoiling runs, avoid band to scratch.Connecting rod 11 pinches under being positioned at all the time in whole swing process on slewing rollers bearing block 5 upper surface, avoids 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 pressure on could driving, in order to avoid damage equipment.Transmission side is identical with fore side.
The present invention not only can increase the opening degree of open-head pinch roll, is convenient to threading; And during upper uncoiling linkage work, and above pinch the roll gap regulation pad that slewing rollers are connected and be pressed on connecting rod, band increases at the upper cornerite pinching slewing rollers place, avoids band and produces scuffing herein.In addition, the present invention's campaign is flexible, there is not stuck phenomenon; No matter be upper uncoiling or lower uncoiling, the cornerite of band at open-head pinch roll place is all identical, and open-head pinch roll all works by identical mode, finally realizes automatic programming by electrical control.
The parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
What finally illustrate is, the present invention is not restricted to the described embodiments, what describe in above-described embodiment and description just illustrates principle of the present invention, and under the prerequisite not departing from the principle and scope of the present invention, various changes and modifications all should be encompassed in the middle of right of the present invention.
