Abstract
The utility model discloses a configuration structure for uncoiling and coiling end parts of a wound roll, which is suitable for a four-wedge-typed wound roll, and is characterized in that: a pressure cover (10) is additionally arranged between a hollow main shaft (6) and an end cover (7), the pressure cover is fixedly connected with the hollow main shaft, and the end cover is fixedly connected with the pressure cover; the middle part of the pressure cover is provided with a cross-shaped through hole, and an axial wedge (1) which is held inside the hollow main shaft stretches out from the cross-shaped through hole of the pressure cover; and a connecting fork (12) is fixed on a mandrel (3) through a hydraulic nut (15), an adjusting nut (13) is installed on the connecting fork (12), the end part of the adjusting nut is propped against the end surface of the axial wedge, a stud (11) passes through the adjusting nut to be fixed on the axial wedge, and a nut piece (14) is screwed onto the end of the stud so as to fix the adjusting nut. Due to adoption of the configuration structure, the processing difficulty of the cross-shaped fork and the axial wedge can be reduced, the structure is simple and convenient to install, and the disassembling and maintenance cost of the structure can be reduced to a certain degree.
Description
Technical field
The utility model relates to uncoiling in the cold rolling unit, batches the reel ends configuration structure, is applicable to the reel of four Wedge types.
Background technology
In conjunction with Fig. 1, Fig. 2, in the existing cold-rolling mill, traditional uncoiling, batch reel ends configuration, be cross jaw 4 to be fixed on the mandrel 3 with round nut 5, inlay card is equipped with 4 four pins of sticking of cross jaw respectively at the axial wedge 1 of 6 li on hollow main shaft.During rotating hydraulic cylinder work, it is flexible together to drive mandrel 3 and cross jaw 4, and axial wedge 1 drives radially wedge 8 liftings under 4 push-and-pulls of cross jaw, fanning strip 2 is distending or retraction under the effect of wedge radially 8 and spring 9 power, the breathing process of Here it is reel.
This shows that cross jaw 4 plays important anastomosis in reel breathing process,, therefore axiality, symmetry, the perpendicularity of four pins on the cross jaw 4 are had relatively high expectations in conjunction with Fig. 3; Simultaneously the uniformity of four axial wedges 1 with cross jaw 4 mating holes also had higher requirements, this has increased the difficulty of processing and the installation difficulty of cross jaw 4 and axial wedge 1 greatly.Cross jaw 4 and axial wedge 1 will reach suitable stiffness, intensity in addition, avoid the wearing and tearing or the degree of wear not simultaneously, easily cause four tool fanning strips, 2 distendings or bounce back inconsistently, and the reel cylindricity does not reach requirement; Also have round nut 5 easy stripped threads loosening, need open and change or reinforce, waste great amount of manpower and man-hour, bring inconvenience to production.Be the device fabrication cost that existing reel ends configuration structure has not only increased the project initial stage, also can produce extra equipment application notice and cost of equipment maintenance.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of new uncoiling, batches the reel ends configuration structure, this structure has reduced the difficulty of processing of cross jaw, axial wedge, and install simple and conveniently, can reduce equipment demolition and maintenance cost to a certain extent.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
Uncoiling of the present utility model, batch the reel ends configuration structure, set up gland between hollow main shaft and end cap, gland and hollow main shaft connect firmly, and end cap and gland connect firmly; Gland middle part is provided with the cross through hole, and the axial wedge that is stuck in the hollow main shaft passes from the cruciform vent of gland; Hydraulic nut will connect jaw and be fixed on the mandrel, adjust nut and be installed on the connection jaw, adjust nut end and withstand on the axial wedge end face, and double-screw bolt passes the adjustment nut and is fixed on the axial wedge, and nut piece screws the fixing nut of adjusting in the double-screw bolt termination.
Be better implement the invention, between described hollow main shaft and the mandrel sliding sleeve be set.
Be better implement the invention, described hollow main shaft end face is provided with liner plate.
When mandrel stretches, successively drive connection jaw, axial wedge axially-movable, axial wedge promotes radially wedge, fanning strip radial motion, and reel has promptly been finished breathing.
Because adopt aforesaid technical scheme, the utility model produces following good effect:
1, the utility model structure is by setting up gland between hollow main shaft and end cap, and the hollow spindle element that so just need not extend is used for the end cap that is connected and fixed, and reduced the length of hollow main shaft, increased the reel ends space.
2, the effect of traditional cross jaw being located in reel, connect, fixing is substituted by connection jaw, adjustment nut, double-screw bolt, nut, change the planform of cross jaw thus, reduced cross jaw, axial wedge difficulty of processing, and installed simple and convenient.
3, hydraulic nut is tightened easily in addition, is difficult for running, has reduced the demolition and maintenance cost.

The specific embodiment
In conjunction with Fig. 4, Fig. 5, reel is fixed by bolts to gland 10 on hollow main shaft 6 end faces after installing by tradition assembling mode, and end cap 7 is connected on the gland 10, gland 10 middle parts process the cross through hole, and the axial wedge 1 that is stuck in 6 li on hollow main shaft passes from gland 10 cruciform vents; In conjunction with Fig. 6, Fig. 7, adjust nut 13 and screw on connection jaw 12 screw holes, to adjust nut 13 ends and withstand on axial wedge 1 end face, double-screw bolt 11 passes adjustment nut 13 and is fixed on the axial wedge 1, tightens fixing with nut 14 again; To connect jaw 12 with hydraulic nut 15 then is fixed on the mandrel 3.So just mandrel 3, axial wedge 1, connection jaw 12, adjustment nut 13 are linked together.When mandrel 3 stretches, successively drive connection jaw 12, axial wedge 1 axially-movable, axial wedge 1 promotes radially wedge 8, fanning strip 2 radial motions, and reel has promptly been finished breathing.
