A kind of mother-son mouth formula roll structure for rolling shaped wire
Technical field
This utility model belongs to rolled stainless steel technical field, especially relates to a kind of mother-son mouth formula roll structure for rolling shaped wire。
Background technology
Roll is the strength member on steel rolling mill's rolling mill, utilizes a pair or the pressure that produces when one group of roll rolls is to roll stone roller steel, process groove, the groove of two or more rolls is assembled up accordingly, just form pass on roll during work。Roll of the prior art is at rolling shaped wire, especially rolling needs to open on roll corresponding pass when having the shaped wire of symmetrical structure, but actually wanting the pass aligned by the groove on upper and lower roll required for being formed is extremely difficult (see Fig. 1)。
Summary of the invention
Problem to be solved in the utility model is to provide a kind of simple in construction, simple operation, the mother-son mouth formula roll structure for rolling shaped wire improved product quality and production efficiency。
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of mother-son mouth formula roll structure for rolling shaped wire, including topping roll and bottom roll, described topping roll is provided with groove, and this groove opening part forms female mouth;Described bottom roll is provided with boss, this boss week side formation rim of the mouth;Described boss can be inserted into and forms mother-son mouth cooperation in groove。
Described groove is set to arch。
Described female mouth is provided with the chamfering structure matched with rim of the mouth。
Owing to adopting technique scheme, as long as the rim of the mouth of female mouth of topping roll Yu bottom roll is aligned matched moulds, ensure that and obtain required pass, simple and practical, simple operation, pass will not be affected because of displacement and then affect product quality, and rim of the mouth may also function as the effect of track, it is ensured that the straight degree of shaped wire after rolling。
The beneficial effects of the utility model are: have simple in construction, simple operation, the advantage improved product quality and production efficiency。
