Abstract
The utility model relates to a positioner for hot rolling rough rolling working roll roller case belongs to rolling mechanical technical field, including the fixed locating pin that sets up on hot rolling rough rolling working roll roller case, the top welding of locating pin has the locating pin reinforcement, and locating pin reinforcement and locating pin phase-match. The utility model welds the positioning pin reinforcing part on the top end of the positioning pin, which not only increases the height of the positioning pin, prolongs the online service time of the positioning pin, reduces the labor capacity of the fitter, but also reduces the investment of the equipment cost and the roller consumption of the line rolling roller; the diameter of a single effective roller of the matched roller increases the thickness of the positioning pin reinforcing piece, the two effective rollers increase the double size, and the utilization rate of the roller is effectively improved.
Description
Technical Field
The utility model relates to a positioner for hot rolling rough rolling working roll roller case belongs to rolling mechanical technical field.
Background
The wear rate of the positioning pin on the roll box of the ledeburite 1500 hot-rolled rough rolling working roll is higher and the service life is short in the daily use process; the replacement of the positioning pin is high in labor intensity and cost, but the replacement is not timely, so that the production is affected, the improper placement is realized, and the roller falls off, so that accidental injury accidents are caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a positioner that is used for hot rolling rough rolling working roll roller case increases the locating pin life-span, prolongs its online live time, reduction in production cost.
In order to realize the purpose, the utility model discloses a technical scheme be:
the utility model provides a positioner for hot rolling rough rolling working roll roller case, is including the fixed locating pin that sets up on hot rolling rough rolling working roll roller case, the top welding of locating pin has the locating pin reinforcement, and locating pin reinforcement and locating pin phase-match.
The utility model discloses technical scheme's further improvement lies in: the locating pin reinforcing piece is a screw cap or a steel plate annular piece.
The utility model discloses technical scheme's further improvement lies in: the height of locating pin reinforcement is 10 mm.
Since the technical scheme is used, the utility model discloses the technological effect who gains has:
the utility model discloses at the top welding locating pin reinforcement of locating pin, both increased the locating pin height, prolonged the online live time of locating pin, reduced the amount of labour of pincers worker, reduced equipment cost's input again and the roller of roll line roll consumes.
The utility model discloses welded the locating pin reinforcement on the top of locating pin, the size of locating pin reinforcement thickness has been increased to the effective roll diameter of single of supporting roll, and two increase double size have effectively improved the utilization ratio of roll.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
wherein, 1, locating pin, 2, locating pin reinforcement.
Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments:
the utility model provides a positioner for hot rolling rough rolling worker roller case, as shown in figure 1, including fixed setting up the locating pin 1 on hot rolling rough rolling worker roller case, the top welding of locating pin 1 has locating pin reinforcement 2, and the size and the locating pin 1 phase-match of locating pin reinforcement 2. Locating pin reinforcement 2 is screw cap or steel sheet annular member, highly is 10 mm. After the locating pin reinforcement 2 is scrapped due to normal abrasion, the use function of the locating pin can be recovered by welding the new locating pin reinforcement 2 again, and the problems of high labor intensity and high operation cost caused by replacing the locating pin are solved.
The utility model welds the positioning pin reinforcing part on the top end of the positioning pin, thereby increasing the height of the positioning pin, prolonging the online service time of the positioning pin, reducing the labor capacity of a fitter, and reducing the investment of equipment cost and the roller consumption of a rolling line roller; meanwhile, the diameter of a single effective roller of the matched roller increases the thickness of the positioning pin reinforcing piece, two effective rollers increase the double size, and the utilization rate of the roller is effectively improved.
