Abstract
A kind of axle key special tool for examination and repair, including portal frame, gantry stand, T-type jacking block, jack, portal frame is fixed on portal frame pedestal, and portal frame and portal frame pedestal are formed by welded steel plate, the intermediate seam opened there are one width slightly larger than axle key diameter on the frame body on portal frame top；Jack is fixed on portal frame pedestal, and the mandril axle center of jack is corresponding with the center line of the seam on frame body, and T-type jacking block is placed on above jack.The utility model is simple in structure, is easy to make, easy-to-operate；Can simple and quick dismounting axle key, effectively avoid the existing irrationality of original equipment dismounting, solve the problems such as abrasion or damage spool mandrel critical component of axle key, reduce maintenance workload, labor intensity of operating staff is reduced, it is long to shorten maintenance time, substantially increases production efficiency.
Description
Technical field
The utility model is related to a kind of cold-rolling mill axle key special tool for examination and repair.
Background technology
Aluminium processing industry, cold-rolling mill spool axle key play the role of connecting mandrel, pass through hydraulic system at work
Axle key band moving mandrel acts, to realize spool harmomegathus.But axle key is also easy to produce abrasion or fracture in the long-term course of work, if
Cannot inspect periodically or replace easily causes spool can not work normally, to cause the generation of safety accident, but normal dismounting
When need manually directly tap axle key with sledgehammer and can dismantle, easily cause the abrasion of axle key or damage spool mandrel, equipment is caused to damage
It is bad（More than 30 ten thousand yuan of spool price）, and artificial percussion for a long time in disassembly process, labor intensity is big, and maintenance time is long, delays life
Production influences yield.
Invention content
Problem to be solved in the utility model is：A kind of axle key special tool for examination and repair is designed, to solve when axle key is dismantled
The problem of axle key damage caused by the gravity that vertical and axle key are fallen or destruction spool mandrel, reduces dismounting cold-rolling mill volume
The work difficulty and labor intensity of axis axle key.
Solve the problems, such as that the utility model is adopted the technical scheme that：It include portal frame, portal frame pedestal, T-type jacking block,
Jack, portal frame are fixed on portal frame pedestal, and portal frame and portal frame pedestal are formed by welded steel plate, on portal frame top
Frame body on, centre open there are one width be slightly larger than axle key diameter seam；Jack is fixed on portal frame pedestal, jack
Mandril axle center is corresponding with the center line of the seam on frame body, and T-type jacking block is placed on above jack.
The utility model has the beneficial effects that：It is simple in structure, it is easy to make, easy-to-operate；It simple and quick can dismantle
Axle key effectively avoids the existing irrationality of original equipment dismounting, solves abrasion or the damage spool mandrel key portion of axle key
The problems such as part, reduces maintenance workload, reduces labor intensity of operating staff, and it is long to shorten maintenance time, substantially increases
Production efficiency.
Description of the drawings
Attached drawing 1 is the use state diagram of the utility model.
Specific implementation mode
As shown in Fig. 1, it includes portal frame 3, gantry stand 8, T-type jacking block 6, jack 7, and portal frame 3 is fixed on dragon
On door frame pedestal 8,3 high 1500mm of portal frame, long 650mm, width 600mm, portal frame 3 and portal frame pedestal 8 by welded steel plate and
At intermediate on 3 top frame body 2 of portal frame to open there are one the seam 1 that width is slightly larger than 5 diameter of axle key, jack 7 uses 50 ton thousand
Jin top, is fixed on portal frame pedestal 8, and the mandril axle center of jack 7 is corresponding with the center line of seam 1 on top frame body 2, T-type
Jacking block 6 is placed on the mandril upper end of jack 7.
In use, cold-rolling mill winding off spindle 4 is penetrated in portal frame 3, T-type jacking block 6 is placed on 7 mandril upper end of jack, will
The 5 lower end aligned T-type jacking block 6 of axle key of winding off spindle 4 is manually operated jack 7, makes T-type jacking block 6 to upper top shaft key 5, in jack
Under the action of 7 upward power, axle key 5 can be ejected, and be unloaded axle key 5 by the seam 1 on 3 top frame body 2 of portal frame.
