Description

Panel assembly is dialled in fixed roll rotation

Technical field

The utility model relates to the auxiliary equipment of steel rolling hot continuous rolling production technology, belongs to the improvement that the grinding machine processing roll is used for the coupling arrangement of dummy roll, and panel assembly is dialled in particularly fixed roll rotation.

Background technology

In hot continuous rolling production technology layout, grinding machine is being born the working roll grinding of main rolling line roughing unit and mm finishing mill unit, wherein the precision rolling working roll grinding machine is two, because rhythm of production is fast, the roll change frequency is many, and the roll demand is big, and the grinding machine relationship between efficiency is to the ordinary production of hot-rolling line, therefore must reduce the grinding machine roll dressing time, improve grinding machine efficient.Present domestic hot continuous rolling grinding machine is in the roll dressing process, all adopt the heavy chuck of 30kg of a monomer, artificial earlier chuck being mentioned is installed on the roll folk prescription, and then lift by crane on the grinding machine centre frame with suspender belt and driving, grinding machine headstock floral disc drive mounted thereto two fixedly thumb wheel stretch out, the floral disc rotation makes two fixedly thumb wheel drive chucks then, the drive roll rotates at a high speed and carries out grinding, after grinding finishes, roll is hung down, artificial more earlier chuck being taken off from the roll folk prescription, 16 minutes times spent, calculate by 8 rolls of per tour grinding in 8 hours, manually install and take off chuck 16 times, because Waldrich grinding machine degree basic fixed, the pure grinding time can't shorten, therefore, the time of installing and taking off chuck becomes the subject matter of restriction grinding efficiency, has influenced stable the carrying out that hot rolling is produced to a great extent because of grinding efficiency is low.

The utility model content

The purpose of this utility model is to provide a kind of fixed roll rotation to dial panel assembly, and it is rational in infrastructure, and is easy to operate, can shorten the grinding machine skiving roll skiving time, improves the grinding efficiency of grinding machine, alleviates working strength of workers.

The purpose of this utility model is achieved in that a kind of fixed roll rotation group panel assembly, comprise grinding machine headstock floral disc, the left side of symmetry, the right plate pedestal of dialling matches with the T-slot of floral disc respectively by the protruding key piece that is provided with on its base bottom surface, and respectively by retainingf key with a left side, the right plate pedestal of dialling connects the location with floral disc, by being fixed on bolt uniform in the floral disc T-slot with a left side, the right plate pedestal of dialling is fastened on the floral disc, a left side, the right perpendicular side plate of dialling the plate pedestal, on its outer panel face dovetail groove is being set, with the uniform dormant bolt that symmetry is installed on the plate of dialling of dovetail groove matched in clearance, dormant bolt by its disk spring of going up installation with a left side, right dial plate respectively with a left side, the right side plate of dialling the plate pedestal couples together.

The utility model has realized that roll directly lifts on the grinding machine centre frame, dial panel assembly by fixed roll rotation and directly drive the roll rotation, enter roll dressing, the roll of the different roll homalocephalus of grinding only needs left and right sides dial move left and right is got final product to suitable centre-to-centre spacing in addition; During the utility model work, the utility model of installing on floral disc and the floral disc stretches out together, directly be transferred on the inclined to one side head of roll, the rotation of drive roll, enter grinding, make the grinding machine roll dressing time reduce to 44 minutes by 55 minutes, the grinding efficiency of grinding machine has improved 20%, has satisfied the demand of hot continuous rolling production line breaker roll.After using the utility model, roll can once not land, and directly lifts on the grinding machine centre frame, realizes grinding, has solved the problem of grinding machine headstock floral disc dummy roll.Very little very little according to the flat square chi of finish rolling F1-F4 working roll with the flat square chi of F5-F6 working roll, shelf position according to institute's grinding roller, fixed pressure roller roll rotation is dialled the left and right two parts of panel assembly and can be adjusted, plate centre-to-centre spacing is dialled in fixed roll rotation adjusted to corresponding size, to satisfy the grinding of different operating roller, improved the grinding efficiency of grinding machine.After adopting the utility model, through using proof: the electric current of grinding machine headstock motor does not have trend of rising, the motor stable drive, and main shaft and main shaft bearing operation are normal.Fixed roll rotation is dialled panel assembly and is driven the roll spin stabilization, and the roll dressing precision meets technological requirement.Because the utility model is directly installed on the grinding machine headstock floral disc, cancelled the dial and the thumb wheel that are installed on the inclined to one side head of roll, optimized structure.

The utility model is rational in infrastructure, and is easy to operate, can shorten the grinding machine skiving roll skiving time, improves the grinding efficiency of grinding machine, alleviates working strength of workers.
