Abstract
The utility model discloses a dismounting tool for a special steel blooming circular disk scissor shaft head sleeve. The dismounting tool comprises a screw rod, a screw sleeve, a hand wheel, three connecting rods and three pull rods. The hand wheel is fixedly arranged at the top end of the screw rod which is screwed in the screw sleeve. One end of each connecting rod is hinged to an outer ring of the screw sleeve, and the other end of each connecting rod is hinged to the middle of each pull rod. The bottom end of each pull rod is provided with a hook foot. The tool brings convenience to dismounting operation of the scissor shaft head sleeve, improves dismounting operation efficiency, reduces the labor intensity of operation, and avoids damage to parts and potential safety hazards in the operation process.
Description
Technical field
The utility model relates to a kind of dismounting frock of special steel breaking down circle shear cutter shaft spindle nose cover.
Background technology
Special steel breaking down circle shear is the key of band steel dimensions precision control, and the circle shear cutter shaft is the core component of circle shear, determines scissor cut precision and service life.There is the dismounting defective in this equipment, need be with the cutter shaft integral demounting when blade bolt is changed usually, but cutter shaft and spindle nose cover are Mohs four degree, its magnitude of interference is bigger, dismounting has big difficulty, and removal efficiency is low, and labour intensity is big, unloading process may damage cutter shaft or other parts, and has certain potential safety hazard.The dismounting of tradition cutter shaft must be at first with the dismounting of the reduction box end cap under the circle shear, and the whole handling of circle shear uses press to implement the cutter shaft dismounting to large-scale press then.The workload of tradition cutter shaft dismounting is big, and it is many to relate to equipment, and the accessory problem that produces because of maintenance also increases thereupon, causes the low of efficient, and the cutter shaft of press dismounting simultaneously may cause cutter shaft to damage in unloading process.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of dismounting frock of special steel breaking down circle shear cutter shaft spindle nose cover, utilize the convenient field-strip of implementing cutter shaft spindle nose cover of this frock, improve field-strip efficient, reduce operations labor intensity, avoid the damage of parts and the potential safety hazard of operation process.
For solving the problems of the technologies described above, the dismounting frock of the utility model special steel breaking down circle shear cutter shaft spindle nose cover comprises screw rod, swivel nut, handwheel, three connecting rods and three pull bars, described handwheel is fixed at described screw tip, described screw rod is twisted in described swivel nut, described three connecting rod one ends are the uniform described swivel nut outer ring that is articulated in respectively, described three connecting rod other ends are articulated in described three pull bars middle part respectively, and described three pull bar bottoms are respectively equipped with the hook pin.
Further, above-mentioned three pull bars middle part is interval with some through holes respectively, and described three connecting rod other ends are articulated in one of some through holes at described three pull bars middle part respectively.
Further, this frock also comprises handle, and described handle is vertical at described handwheel outer ring.
Because the dismounting frock of the utility model special steel breaking down circle shear cutter shaft spindle nose cover has adopted technique scheme, be that this frock comprises screw rod, swivel nut, handwheel, three connecting rods and three pull bars, handwheel is fixed at screw tip, screw rod is twisted in swivel nut, three connecting rod one ends are the uniform swivel nut outer ring that is articulated in respectively, three connecting rod other ends are articulated in three pull bar middle parts respectively, and three pull bar bottoms are respectively equipped with the hook pin.The convenient field-strip of implementing cutter shaft spindle nose cover of this frock improves field-strip efficient, reduces operations labor intensity, avoids the damage of parts and the potential safety hazard of operation process.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the dismounting frock of the utility model special steel breaking down circle shear cutter shaft spindle nose cover.
The specific embodiment
As shown in Figure 1, the dismounting frock of the utility model special steel breaking down circle shear cutter shaft spindle nose cover comprises screw rod 1, swivel nut 2, handwheel 3, three connecting rods 5 and three pull bars 4, described handwheel 3 is fixed at described screw rod 1 top, described screw rod 1 is twisted in described swivel nut 2, described three connecting rod 5 one ends are uniform described swivel nut 2 outer rings that are articulated in respectively, described three connecting rod 5 other ends are articulated in described three pull bar 4 middle parts respectively, and described three pull bar 4 bottoms are respectively equipped with hook pin 41.
Further, above-mentioned three pull bar 4 middle parts are interval with some through holes 42 respectively, and described three connecting rod 5 other ends are articulated in one of some through holes 42 at described three pull bar 4 middle parts respectively.The setting of three some through holes in pull bar middle part is convenient to adjust the length of pull bar, is applicable to the field-strip of different size cutter shaft.
Further, this frock also comprises handle 6, and described handle 6 is vertical at described handwheel 3 outer rings.Can light rotation handwheel by handle, make things convenient for the operation of this frock.
When the field-strip of cutter shaft spindle nose cover, at first that cutter shaft is outer blade is removed, use driving or crane to lift by crane this frock that assembles then and be positioned at spindle nose and overlap the outside, with the feet hook of three pull bars of this frock on the ring flange of spindle nose cover, between swivel nut and cutter shaft, place the 50T oil cylinder, rotation hand wheel makes screw rod hold out against the 50T oil cylinder and adjusts three draw rod positions, make hook pin and the ring flange of three pull bars that certain contact force be arranged, adopt three above baking rifle evenly heated the cutter shaft ecto-entad, guarantee the uniformity of cutter shaft heating, guaranteeing that enough heating-up temperatures are connected with this frock under the intact firm situation, start 50T oil cylinder pushing tow cutter shaft, under the effect of three pull bar hook pin, cutter spindle sleeve is slowly pulled out from cutter shaft, finish the field-strip of cutter spindle sleeve.
