Description

A kind of axle head supporting arrangement of coiling machine spool

Technical field

The utility model belongs to metallurgical cold-strip steel equipment technical field, is specifically related to a kind of axle head supporting arrangement of coiling machine spool.

Background technology

Coiling machine is a metallurgy industry cold rolling of strip steel workshop key equipment commonly used, and the band that shuts out is rolled into coil of strip, and wherein the axial wedge Shrink formula reel that rises is exactly wherein a kind of, and the axial wedge Shrink formula reel major part that rises comprises main shaft, fanning strip and end cap.End cap is installed in the end of main shaft, the internal point of its big end cooperates with the centering of spindle nose cylindrical, and with trip bolt with its axial location, spool to cantilever plays a supportive role, because spindle nose is four claw type structures, its rigidity is weakened, the big stomidium contact area of cylindrical and end cap also significantly reduces simultaneously, in the strip coiling process, because of the tension force of being with steel makes end cap bear bigger alternate load, this load passes to the four paws of spindle nose, because spindle nose four paws poor rigidity makes its cylindrical and end face and end cap hole wall and contact position, bottom surface sharp wear, cause trip bolt loosening, end cap loses centering and supporting role, and severe patient will cause the four paws fracture of spindle nose.

Summary of the invention

The utility model provides a kind of axle head supporting arrangement of coiling machine spool, solve that existing axial wedge Zhang Shrink formula reel end cap trip bolt is easily loosening, spindle nose four paws cylindrical and the end cap contact site is easy to wear, the four paws easy fracture of spindle nose, feel relieved and support insecure problem.

The technical scheme that the utility model adopted is, a kind of axle head supporting arrangement of coiling machine spool, comprise spool spindle and the end cap that is installed in the spool spindle end, one end of spool spindle is the four paws structure, each pawl termination is equipped with axial tightening screw, and the four paws circumference profile constitutes circle in concentric four paws cylindrical and the four paws together; The big end of end cap is provided with internal point, internal point cooperates with the four paws cylindrical centering of spindle nose, also be provided with four axial joint holes and spool on the end cap small end and support outer conical surface, in four axial joint holes, axial tight fixed bolt is installed, also be provided with four radially tightening adjusting screws on the big end circumference of end cap, radially tightening adjusting screw is radially consistent with axial joint hole separately for each, and is communicated with internal point, and the four paws inner circle in the internal point bottom is provided with a reinforcing ring.

The utility model device characteristic is that also reinforcing ring cooperates for no gap with the interior circle of four paws.

Spool shaft end bearing of the present utility model is simple in structure, has improved spindle nose four paws rigidity, strengthens roller tube end centering and supporting role, uses more reliable.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Fig. 1 is existing axial wedge Zhang Shrink formula reel assembling schematic diagram, and the end cap A1 of prior art is installed in the end of main shaft 2, and fixes by axial tight fixed bolt 3.

Fig. 2 is the schematic diagram of the axial wedge Zhang Shrink formula spool spindle among Fig. 1, one end of spool spindle is the four paws structure, the axle center that each pawl termination is equipped with the four paws of axial tightening screw 5, spindle nose is positioned on the circle, and the four paws circumference profile constitutes circle 15 in concentric four paws cylindrical 6 and the four paws together.

Fig. 3 is the structural representation of the axial wedge Zhang Shrink formula reel end cap A1 among Fig. 1, and Fig. 4 is the three-dimensional structure schematic diagram of existing axial wedge Zhang Shrink formula reel end cap A1.The big end of end cap A1 is provided with internal point 8, end cap A1 small end is provided with four axial joint holes 7 and spool supports outer conical surface 9, internal point 8 cooperates with four paws cylindrical 6 centering of spindle nose, coiling machine external means of support (not drawing among the figure) is enclosed within on the spool support outer conical surface 9 during work, axially tight fixed bolt 3 is installed in four axial joint holes 7, and the reel and the spool of cantilever played the support positioning action.

Fig. 5 is the structural representation of axial wedge Zhang Shrink formula reel end cap 10 of the present utility model, on the existing structure of end cap A1, also be provided with four radially tightening adjusting screws 11 on the end cap 10 big end circumference, radially tightening adjusting screw 11 is radially consistent with each axial joint hole 7 for each, and be communicated with internal point 8, constitute new end cap 10 structures.
