Description
Technical Field
The utility model relates to an assembly and disassembly tools, concretely relates to reel spindle nose dismouting specialized tool.
Background
The 4AP continuous annealing and pickling unit in stainless steel enterprises is a continuous production unit for annealing, pickling and leveling a cold-rolled stainless steel coil to obtain a finished stainless steel coil, and the unit comprises an uncoiler, a head-tail welding machine, an inlet loop, an annealing furnace, a pickling section, an outlet loop, a temper mill, a coiling machine and other equipment. The production process speed of the unit is 120m/min, the maximum speed of the inlet and the outlet is 160m/min, the thickness of the strip steel is 0.15-2.0mm, and the width is 650-1350 mm. Wherein the coiler equipment is supplied by DMS.
The maintenance standard of the coiler mandrel is to perform disassembly inspection on the mandrel every year and inspect the inner wear condition of the mandrel. The winding drum is composed of a main shaft, a sector plate, a bell-shaped cover and a shaft head, when the winding drum is maintained, the winding drum needs to be disassembled, the winding drum is disassembled in sequence, the shaft head is disassembled firstly, then the bell-shaped cover is disassembled, and finally the sector plate is disassembled. The spindle nose is through interference fit suit on the main shaft, because fit clearance is little, and the dismouting space is narrow and small, does not have suitable specialized tool again during the dismouting, wastes time and energy when leading to the dismouting, when striking or with the pinch bar, misuse causes equipment to damage easily, has seriously influenced the repair time of equipment.
Therefore, a special tool for disassembling and assembling the winding drum shaft head needs to be designed, so that the disassembling and assembling time is reduced, and the overhauling efficiency is improved.
Disclosure of Invention
The utility model aims to solve the technical problem that a simple structure is reasonable, the safe convenient reel spindle nose dismouting specialized tool of operation is provided to foretell technical current situation.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a reel spindle nose dismouting specialized tool which characterized in that: this dismouting specialized tool includes the bottom plate, roof and hydraulic jack, wherein the bottom plate, roof parallel arrangement is equipped with the guide pillar between and, be equipped with the connecting hole corresponding with the epaxial screw hole of the spindle of reel on the bottom plate, hydraulic jack perpendicular to bottom plate is installed at the middle part position of bottom plate, hydraulic jack's outer end corresponds with the tip of main shaft and offsets, when dismantling the spindle nose, pass through bolted connection with bottom plate and spindle nose and fix, start hydraulic jack, pressure through hydraulic jack realizes that the spindle nose breaks away from the main shaft.
As an improvement, the bottom plate and the top plate are both circular plates, and the guide posts are uniformly distributed on the circumference.
Preferably, the guide posts are two parallel up and down.
Further, still install the button head ejector pin coaxial with hydraulic jack on the roof, button head ejector pin is installed on the roof, through hydraulic jack's stroke adjustment button head ejector pin on the roof with adjustable.
And finally, the hydraulic jack is arranged at the central position of the bottom plate, and the round head ejector rod is correspondingly arranged at the central position of the top plate.
Compared with the prior art, the utility model has the advantages of: the spindle head is fixed with the spindle head through the bottom plate during disassembly, and the spindle head is disassembled from the spindle through the acting force of the hydraulic jack. The utility model has the advantages of simple and reasonable structure, easy operation is convenient, and labour saving and time saving has improved work efficiency greatly, has still avoided the emergence of incident simultaneously, is applicable to the spindle nose of DMS reel and dismantles.

fig. 2 is a side view of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and 2, a special tool for disassembling and assembling a winding drum shaft head, the special tool for disassembling and assembling a winding drum shaft head comprises a bottom plate 1, a top plate 2, a guide pillar 3, a hydraulic jack 4 and a round head ejector rod 5, wherein the bottom plate 1 and the top plate 2 are both circular, the two are arranged in parallel, the guide pillar 3 is two, certainly not limited to two, but also can be multiple, the special tool is arranged between the bottom plate 1 and the top plate 2, a connecting hole 11 corresponding to a threaded hole in the shaft head of the winding drum is formed in the bottom plate 1 in the circumferential direction, the hydraulic jack 4 is perpendicular to the bottom plate 1 and is arranged at the central position of the bottom plate 1, the outer end of the hydraulic jack 4 corresponds to and offsets with the end of a main shaft, the round head ejector rod 5 can be arranged at the central position of the top plate 2 in a.
The specific operation process is as follows: when the spindle head is disassembled, the end cover on the spindle head is disassembled firstly, the connecting hole 11 on the bottom plate 1 and the threaded hole on the spindle head are fixedly connected through the bolt, the hydraulic jack 4 is started, and the spindle head is moved under the pressure of the hydraulic jack 4, so that the spindle head is finally separated from the spindle to be disassembled.
Through actual implementation, better effect has been obtained after the special assembly and disassembly tools of this embodiment of adoption: 1. the disassembly and assembly time is reduced from 4 hours to 0.5 hour; 2. the overhaul labor efficiency is improved; 3. the equipment damage and the safety hazard accidents caused by improper disassembly and assembly are avoided.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
