Abstract
The utility model discloses a roller group for a universal mill, which comprises an upper horizontal roller with two upper bearing pedestals, a lower horizontal roller with two lower bearing pedestals, a pair of vertical rollers with vertical roll bearing pedestals respectively and a quick roller-changing device, wherein the quick roller-changing device comprises a lower horizontal roller positioning rod, a vertical roller positioning rod, an upper horizontal roller positioning rod and a liftable roller-changing trolley. When the roller is changed, the roller-changing trolley rises to drive the positioning rods to stretch into counter bores which are correspondingly arranged on the bearing pedestals in order to achieve reliable supporting and positioning, so that the roller group forms a whole; the roller group for a universal mill can avoid the relative movement of each roller and the abrasion of the positioning rod when the roller group is quickly removed or loaded, and the interlocking is reliable; the roller-changing trolley falls when working and all the supporting and positioning relations can be relieved, so that the roller group is quickly put to work. The roller group for a universal mill has a simple and reasonable structure, and can effectively improve the reliability and the maintainability of the roller group, reduce the difficulty of roller-changing operation, reduce the roller-changing time and improve the production efficiency.
Description
Technical field
The utility model relates to the shaped steel production equipment, particularly a kind of parts of universal mill.
Background technology
At present, the universal rolling method has generally been adopted in the production of shaped steel, wherein universal mill is to carry out the main equipment that shaped steel is produced, in the operation of rolling of universal mill, roll wear is very fast, need often to change roll stacks, therefore, the time length of roll change operation has determined the production efficiency of universal mill to a great extent.
Roll change technological requirement: when the roll change operation, the bearing block of the upper and lower horizontal roller of roll stacks and left and right edger roll bearing block need to support mutually the location, form an integral body, and roll stacks is packed into behind the milling train, need to remove this support positioning relation again, make upper and lower horizontal roller can move up and down freely and left and right edger roll can move in the horizontal direction freely.The difficult point that realizes these functions is, how making up suitable device makes each roll form effective support location and release relation, and make it to become a reliable system, particularly owing to have layer edger roll need support under the situation with release construction device in the middle of the roll stacks to make horizontal roller also form effective support simultaneously to locate and release, after edger roll and the release of top roll supporting relation, can make horizontal roller continue to move downward, and not influence the horizontal direction freely-movable of edger roll.
In the prior art, patent 03156744.4 discloses a kind of roll stacks that is used for universal frame, support interlocking by supporting pin and strut between each roll of this roll stacks and form integral body, satisfy the whole technological requirement that moves into or shift out frame of roll stacks, but still there is following some deficiency in this technology: the described vertical roller of a. just is positioned over described supporting bar top, vertical roller still can move in the horizontal direction, do not form reliable interlocking, when roll stacks shifts out or move into frame, support bar just relies on the frictional force with the vertical roller upper rail to drive vertical roller and shifts out or move into, cause the location interlocking capability of vertical roller relatively poor, make roll stacks immigration or shift out limited speed, milling train can not comparatively fast be devoted oneself to work, simultaneously, and when milling train is worked, vertical roller reciprocating motion in the horizontal direction, with guide groove and supporting bar top on the vertical roller are worn and torn mutually, cause the further variation of its interlocking capability, after the serious wear even cause the problem that to pull out vertical roller; B. the described horizontal roller that goes up is supported by the supporting pin on the vertical roller, move release by spring block, slide block is removed the back and is formed certain space, make horizontal roller can continue to move downward, and vertical roller is freely-movable in the horizontal direction also, but its immigration or to shift out also be frictional force by between the slide block on supporting pin and the last horizontal roller, same location interlocking capability is relatively poor, be difficult to form reliable interlocking, and go up the spring block mechanism structure complexity of horizontal roller, operation inconvenience, under abominable operating mode, reliability is low, and is maintainable poor, is difficult to effectively be used at rolling scene.
Therefore, need to explore a kind of roll stacks that is used for universal mill, make it can form and remove the support positioning relation fast, interlocking is reliable, so that roll stacks is packed into fast or take out rolling-mill housing, reduce the difficulty of roll change operation, and reduce roll changing time and make milling train enter duty fast, improve the production efficiency of universal mill.
