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 advantages such as efficient, material-saving, has at home and abroad obtained using more widely.Along with the continuous development of cross wedge rolling technology, to the requirement of equipment also heal come high more.At present the roll system of cross wedge rolling machine is overall structure, after Mould Machining finishes, is installed on the roll of roll system, rolls through examination and carries out corresponding die debugging (comprising repairing and the position adjustment of mould etc.).But the artifact influence is very big in the debug process of mould, 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 is greatly and more complicated, more strengthens in the machine debugging difficulty, and the time is also longer.
Summary of the invention
Technical problem to be solved by this invention provides a kind of roll system that solves the changeable type cross wedge rolling mill roller of the problem that big and complicated mould is big in the machine debugging difficulty, the time is long.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: 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 its bearing block that belongs to a side, and the two ends of described roll are set with link respectively, is provided with dismountable mechanism that is fixedly connected between described link and the described backing roll.
Described fixed connection mechanism comprises connecting key; Described backing roll is provided with mounting platform; Described connecting key is fixedly mounted on the centre position of described mounting platform vertically, and described link and described mounting platform are complementary, and described link is 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, are connected with connecting bolt in described first fluting, and described link is provided with and corresponding second fluting of described first slotting position; Described connecting bolt inwardly is transferred in described second fluting and through nut and is fixedly connected with described link, is set with alignment pin between described link and the described mounting platform.
Described connecting bolt is coupling in described first fluting through bearing pin, is socketed with copper sheathing on the described bearing pin, and described copper sheathing is between described bearing pin and described connecting bolt.
Described backing roll is connected on the described bearing block through bearing shaft, and the end of described backing roll is provided with locking nut, and the both sides of described bearing block are set with bearing (ball) cover.
Compared with prior art, advantage of the present invention is owing to be provided with dismountable mechanism that is fixedly connected between the link of roll and the backing roll, makes the roll in the roll system replaceable; Mould Machining need not be carried out die debugging after accomplishing on equipment, thereby greatly reduces the debugging difficulty of big and complicated mould; Also saved debug time; Increase substantially the utilization of capacity of equipment, made full use of device resource, realized rolling high efficiency, the large-scale production of macrotype axes series parts cross wedge rolling.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in the figure, a kind of roll system of changeable type cross wedge rolling mill roller comprises roll 1 and the backing roll 2 that is positioned at roll 1 two ends; Backing roll 2 is coupling through bearing 3 and belongs on the bearing block 4 of a side at it, and the end of backing roll 2 is provided with locking nut 21, and the both sides of bearing block 4 are set with bearing (ball) cover 41; The two ends of roll 1 are welded with link 11 respectively, have been wholely set mounting platform 22 on the backing roll 2, and the centre position of mounting platform 22 is installed with the connecting key 5 that is provided with vertically through screw; Link 11 is complementary with mounting platform 22; Link 11 is provided with keyway (not marking among the figure), and connecting key 5 matches with keyway, and the both sides of mounting platform 22 are respectively arranged with two first flutings 23 radially; Be connected with connecting bolt 7 through bearing pin 6 in first fluting 23; Be socketed with copper sheathing 61 on the bearing pin 6, copper sheathing 61 is between bearing pin 6 and connecting bolt 7, and link 11 is provided with and corresponding second fluting 12 in first fluting, 23 positions; Connecting bolt 7 inwardly is transferred in second fluting 12 and through nut 8 and is fixedly connected with link 11, is set with alignment pin 9 between link 11 and the mounting platform 22.
In the foregoing description; The installing and replacing process of roll is in this roll system: the link 11 of roll 1 is placed on the mounting platform 22 of backing roll 2; And both are matched, and the connecting key 5 that is fixedly mounted on the mounting platform 22 is used to transmit moment of torsion, and turning cylinder is connected on the connecting bolt 7 on the mounting platform 22 inwards then; Connecting bolt 7 is transferred in second fluting 12 of link 11; And the mounting platform 22 of fastening nut 8 link 11 that makes roll 1 and backing roll 2 fixes, and stamps alignment pin 9 at last, promptly accomplishes the installation of roll 1; When needs are pulled down roll 1, back out nut 8, laterally rotate connecting bolt 7; Make connecting bolt 7 break away from second fluting 12 on the link 11; Lay down alignment pin 9 then, just can roll 1 be pulled down the mould that machines from backing roll 2; Carry out off-line debugging on the roll of pulling down as long as be installed in, after debugging is accomplished again with roll install together in roll system.
