Abstract
The invention discloses a roll system of a replaceable-roll type cross wedge rolling mill, which comprises a roll and two supporting rolls. The two supporting rolls are respectively arranged at two ends of the roll and are coupled to bearing blocks on the corresponding sides, connecting ends are fixedly arranged on two sides of the roll respectively, and a detachable fixing and connecting mechanism is arranged between each connecting end and each supporting roll. The roll system of the replaceable-roll type cross wedge rolling mill has the advantages that the roll in the roll system can be replaced by the aid of the detachable fixing and connecting mechanisms respectively arranged between the connecting ends of the rolls and the supporting roll, mould debugging on equipment is omitted after moulds are processed, and accordingly debugging difficulty of large and complicated moulds is reduced greatly, debugging time is saved, equipment operation rate is increased greatly, equipment resources are utilized sufficiently, and high-efficiency and large-scale cross wedge rolling production of large-size shaft parts is realized.
Description
Technical field
The present invention relates to a kind of cross wedge rolling mill roller, relate in particular to a kind of roll system of changeable type cross wedge rolling mill roller.
Background technology
Cross wedge rolling is a kind of New Forming Process of axial workpiece, has the advantages such as efficient, material-saving, has at home and abroad obtained applying more widely.Along with the development of cross wedge rolling technology, to the requirement of equipment, also more come higher.At present the roll system of cross wedge rolling machine is overall structure, after Mould Machining, is installed on the roll of roll system, by examination, is rolled and is carried out corresponding die debugging (comprising the repairing of mould and position adjustment etc.).But in the debug process of mould, artifact impact is very large, and particularly for unskilled operative employee, the time of die debugging needs 3-5 days sometimes, has occupied a large amount of device fabrication time, has had a strong impact on the utilization of capacity of equipment.And along with the promotion and application of Multi-wedge Cross Wedge Rolling rolling technique on Rail vehicle axle and automobile axle shaft, its mould greatly and more complicated, more strengthens in machine debugging difficulty, and the time is also longer.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of roll system of the changeable type cross wedge rolling mill roller that solves the problem that large and complicated mould is large in machine debugging difficulty, the time is long.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of roll system of changeable type cross wedge rolling mill roller, comprise roll, the two ends of described roll are respectively arranged with backing roll, described supporting roller is connected on the bearing block of its place one side, the two ends of described roll are fixedly installed respectively link, are provided with dismountable mechanism that is fixedly connected with between described link and described backing roll.
The described mechanism that is fixedly connected with comprises connecting key, on described backing roll, be provided with mounting platform, described connecting key is fixedly mounted on the centre position of described mounting platform vertically, described link and described mounting platform match, on described link, be provided with keyway, described connecting key matches with described keyway, the both sides of described mounting platform are respectively arranged with at least one first fluting radially, in the first described fluting, be connected with connecting bolt, on described link, be provided with second fluting corresponding with the first described slotting position, described connecting bolt is inwardly transferred in the second described fluting and is fixedly connected with described link by nut, between described link and described mounting platform, be fixedly installed alignment pin.
Described connecting bolt is coupling in described the first fluting by bearing pin, on described bearing pin, is socketed with copper sheathing, and described copper sheathing is between described bearing pin and described connecting bolt.
Described backing roll is connected on described bearing block by bearing shaft, and the end of described backing roll is provided with locking nut, and the both sides of described bearing block are fixedly installed bearing (ball) cover.
Compared with prior art; advantage of the present invention is owing to being provided with dismountable mechanism that is fixedly connected with between the link of roll and backing roll; make the roll in roll system replaceable; after Mould Machining completes, need not on equipment, carry out die debugging, thereby greatly reduce the debugging difficulty of large and complicated mould; also saved debug time; the utilization of capacity that has increased substantially equipment, takes full advantage of device resource, realizes high efficiency, the large-scale production of macrotype axes series parts Regularity of Workpiece of Cross Wedge Rolling.
