Description
Technical field
The utility model belongs to the metallurgical engineering technical field, relates to a kind of Wedge type coiler mandrel.
Background technology
Coiler mandrel is the equipment that the band coil of strip after rolling becomes coil of strip with rolling mill for metal, and coiler mandrel mainly all is made up of pyramid that is fixed together with spool and secter pat etc. usually.Spool is two kinds of different materials with pyramid, thus its connection or adopt screw to fix, or take the built-up welding mode to connect.Pyramid adopts the fixing method of screw, can cause drum diameter increase to a certain degree; And there is bigger thermal deformation in the mode of built-up welding, makes processing become difficult, and the coiler mandrel of this structure, and integral rigidity is lower.And on such as the electrotinning production line,, needing the reel of a kind of minor diameter, superpower rigidity from the requirement of technology, the coiler mandrel of existing structure just can not meet the demands.
Summary of the invention
The purpose of this utility model provides a kind of Wedge type coiler mandrel, is applicable to the technological requirement that satisfies minor diameter, superpower rigidity reel.
The technical scheme that the utility model adopted is, the Wedge type coiler mandrel, comprise that an end is fixed with the reel of being made up of a plurality of fanning strips of end cap, the outer surface of the reel of being made up of a plurality of fanning strips is cylindrical, inner surface is provided with a plurality of wedge grooves that link to each other successively, be provided with wedge in the inner chamber of fanning strip, the inside of this wedge is circular cylindrical cavity, the outer surface of wedge is provided with a plurality of wedge protruding blocks that link to each other successively, wedge groove tabling on this wedge protruding block and the fanning strip, the termination of the wedge close with end cap is provided with flange, stretch into a hollow shaft in the inner chamber of wedge, this hollow shaft stretches between interior end of wedge and the end cap and leaves a segment distance, the external diameter of this hollow shaft and the internal diameter of wedge adapt, hollow shaft is played a supportive role to wedge, and wedge is moved axially on hollow shaft, the two ends that one screw rod passes flange and screw rod fixes with the termination and the end cap of hollow shaft respectively, flange can move axially on screw rod, insert the pull bar that is promoted by outside harmomegathus cylinder in the inner chamber of hollow shaft, the end that this pull bar stretches in the hollow shaft is connected with flange.
Coiler mandrel of the present utility model, the inner surface of fanning strip are that a plurality of wedge shapes are connected to form successively, and the outer surface of wedge is that a plurality of wedge shapes are connected to form successively, the wedge shape tabling of the wedge shape of wedge outer surface and fanning strip inner surface.When same coil diameter, the volume of coiling machine is heavy can be increased dramatically, and in limited spatial dimension, can greatly increase the integral rigidity of reel.
Description of drawings
Fig. 1 is the structural representation of the utility model coiler mandrel;
Fig. 2 is the profile at A-A place among Fig. 1;
Fig. 3 is the structural representation of wedge in the utility model coiler mandrel.
Among the figure, 1. hollow shaft, 2. pull bar, 3. wedge, 4. fanning strip, 5. axle sleeve, 6. screw rod, 7. flange, 8. end cap, 9. opening.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the utility model coiler mandrel as shown in Figure 1, comprise that an end is fixed with the columniform reels that curled and formed by three fanning strips 4 of end cap 8, the inner surface of this fanning strip 4 is provided with a plurality of wedge grooves that link to each other successively, be provided with wedge 3 in the inner chamber of fanning strip 4, the inside of this wedge 3 is circular cylindrical cavity, the outer surface of wedge 3 is provided with a plurality of wedge protruding blocks that link to each other successively, wedge groove tabling on this wedge protruding block and the fanning strip 4, the termination of the wedge 3 close with end cap 8 is provided with flange 7, stretch into a hollow shaft 1 in the inner chamber of wedge 3, this hollow shaft 1 stretches between end in the wedge 3 and the end cap 8 and leaves a segment distance, the internal diameter of the external diameter of this hollow shaft 1 and wedge 3 adapts, 1 pair of wedge 3 of hollow shaft is played a supportive role, and wedge 3 is moved axially on hollow shaft 1, the two ends that one screw rod 6 passes flange 7 and screw rod 6 fixes with the termination and the end cap 8 of hollow shaft 1 respectively, flange 7 can move axially on screw rod 6, insert the pull bar 2 that is promoted by outside harmomegathus cylinder in the inner chamber of hollow shaft 1, the end that this pull bar 2 stretches in the hollow shaft 1 is connected with flange 7.A is the extreme position that flange 7 slides into axle sleeve 5 one ends among the figure, and b is the extreme position that flange 7 slides into end cap 8 one ends.
Fig. 2 is the profile at A-A place among Fig. 1, as shown in Figure 2, comprises the columniform reel that three fanning strips 4 curl and form, and in three fanning strips 4 wedge 3 is arranged, and is fixed with hollow shaft 1 in the wedge 3, and hollow shaft inserts a pull bar 2 for 1 li.
Fig. 3 is the structural representation of the utility model wedge 3, and the outer surface of wedge 3 is that the wedge shape of a plurality of continuous settings is formed, and inner surface is cylindrical, and wedge 3 is provided with opening 9.
During work, the harmomegathus cylinder pushing drawing rod 2 that is connected with pull bar 2 endwisely slips, pull bar 2 promotes flange 7 and slides to the b place from a, with the fixing wedge 3 of flange 7 under the drive of flange 7 also the end to end cap 8 move, at this moment because the inclined-plane of fanning strip 4 inside is subjected to the effect of wedge 3 inclined-plane pressure, fanning strip 4 is done radial motion along hollow shaft 1, makes the coil diameter of fanning strip 4 become big, thereby changes coil diameter.Because inside and outside two faces of wedge 3 keep in touch with hollow shaft 1 and fanning strip 4 respectively all the time, wedge 3 two-sided pressurizeds, stress is good, so when identical coil diameter, increased the integral rigidity of reel.
Owing to increased reel rigidity significantly, the volume of coiling machine is heavy can be increased more than 30%.As the reel of coil diameter φ 420, roll up usually and heavyly can arrive 15 tons, and use the reel of the utility model structure, roll up and heavyly reach 20 tons.
