A kind of band steel guide and guard of adjusting width
Technical field
The utility model belongs to a kind of steel rolling metallurgical equipment, specifically is a kind of band steel guide and guard.
Background technology
Guide and guards be in the continuous section rolling system before finished product and in finished product sortie rolling with rolled piece accurately guiding enter roll pass and prevent the rolled piece surface by a kind of device of scratch, its guiding accuracy is related to rolled piece quality and production safety.
Existing band steel guide and guard be made up of casing, left and right side plate, eccentric deflector roll etc., but the width of band steel guide groove can not be adjusted, if need to produce the band steel of different size in the rolled piece production line, then need to change the band steel guide and guard, increased the generation equipment cost, also very inconvenient, incur loss through delay and produce.
The utility model content
The purpose of this utility model provides a kind of band steel guide and guard of adjusting width, can adjust the width of guide groove, when production line need be produced the band steel of different size, only needing to adjust a band steel guide plate gets final product, very convenient, do not need the band steel guide and guard that more renew, saved the time, reduced the equipment investment expenditure again.
The technical solution of the utility model is as follows:
A kind of band steel guide and guard of adjusting width, include casing, left and right side plate, eccentric deflector roll is installed on the left and right side plate, it is characterized in that described left and right side plate lower end cooperates installation with vertical dovetail groove on the box bottom, left and right band steel guide plate is installed between the described left and right side plate, there is bearing in described base central authorities, be separately installed with bolt on the described left and right side plate, described bolt withstands on the bearing.
Compare with existing band steel guide and guard, the utility model band steel guide plate need not adjusted, the position that only needs to adjust left and right side plate gets final product, because left and right band steel guide plate is installed on the left and right side plate, along with left and right side plate moves, left and right side plate is slidingly matched by the dovetail and the base of its bottom, so adjustment is very convenient, make the band steel guide and guard realize flexible production, same secondary band steel guide and guard, can produce the band steel of different size, save equipment investment.
