Synchronizing moving.There are four pieces of wedges on every piece of fanning strip, it is corresponding to be slided on the four bank or ridge wedge surface of main shaft, realize rising for outside diameter of mandrel
Contracting.A T-shaped suspension hook is respectively set on the wedge at fanning strip both ends, and in two T-shaped grooves being respectively placed on main shaft, T-shaped suspension hook
Slided with fanning strip in main shaft T-shaped groove, fanning strip and main shaft is combined as a whole.
, problems be present in the steel roll opener mandrel of said structure：
（1）Two T-shaped suspension hooks are provided with wedge altogether, there are two T-shaped grooves on the main shaft coordinated with it, is using process
In, the T-shaped groove notch on the T-shaped suspension hook and main shaft on fanning strip wedge is easily broken, and any one T-shaped suspension hook
Or T-shaped groove notch is broken, secter pat can all be separated and fallen with main shaft；
（2）Sliding surface is steel and steel friction between hydraulic steering gear adopting cross piece and fanning strip, and sliding surface is easily worn, and entirety is needed after abrasion
Change, cost is high, and not easy care；
（3）Mandrel pull bar bears stretch bending combination fatigue stress, is easily broken in end thread connection stress raiser.
Utility model content
The utility model purpose is to provide a kind of steel roll opener mandrel, and steadily freely, main shaft and fanning strip combine harmomegathus
Reliably, sliding surface is wear-resistant between hydraulic steering gear adopting cross piece and secter pat, reduces flexural deformation and the stress of pull bar, solves to deposit in background technology
The problem of.
The technical solution of the utility model is：
A kind of steel roll opener mandrel, include main shaft, pull bar, hydraulic steering gear adopting cross piece, expanding/shrinking cylinder, fanning strip, wedge, T-shaped suspension hook and T
Connected in star, pull bar are located in the hollow axis hole of main shaft, and one end of pull bar is threadedly coupled with expanding/shrinking cylinder, and the other end of pull bar passes through ten
Block is connected with four pieces of fanning strips, and four pieces of fanning strips are evenly distributed in the circumferential direction on main shaft, set on every piece of fanning strip
There are four pieces of wedges, every piece of wedge is provided with a T-shaped suspension hook, and main shaft is provided with the T-shaped groove being engaged with T-shaped suspension hook.
Sliding surface between the hydraulic steering gear adopting cross piece and fanning strip is provided with slide plate.
The main shaft both ends are provided with the support ring being engaged with pull bar.
T-shaped suspension hook on the wedge is located in the T-shaped groove on main shaft.
The T-shaped suspension hook is slidably connected with T-shaped groove.
The expanding/shrinking cylinder is bolted on the end face of main shaft.
Using the utility model, four pieces of wedges are set on every piece of fanning strip, every piece of wedge is provided with a T-shaped suspension hook, i.e.,
One or two T-shaped suspension hook or T-shaped groove notch are damaged, still there is three or two T-shaped suspension hooks and T-shaped groove notch
Stress, fanning strip and main shaft also will not fall off, and mandrel still can harmomegathus freely.On sliding surface between hydraulic steering gear adopting cross piece and fanning strip
Increase slide plate, improve wearability.Main shaft both ends increase support ring, improve the bending stiffness of pull bar, reduce the bending of pull bar
Deformation and stress, reduce pull bar fracture.
The beneficial effects of the utility model are：Mandrel harmomegathus is steady freely, main shaft and fanning strip combine it is reliable, hydraulic steering gear adopting cross piece and
Sliding surface is wear-resistant between secter pat and easy care, and pull bar is not easy to break, service life length, is adapted to lead in steel roll opener equipment
Domain popularization and application.
