Abstract
The utility model discloses a gripping head of a roll changing rig for a multi-roll mill. The gripping head comprises an upper gripping head and a lower gripping head, wherein, the lower gripping head is a long block; the surface of the long block facing to a roller is in the shape of a circular arc; one end of the lower gripping head is connected with a lower gripping head seat; the upper gripping head is a rectangular block, of which the lower end is branched off; the upper end of the upper gripping head is connected with an upper gripping head seat; the gripping head also comprises a lower shim block in the shape of a circular arc and an upper shim block in the shape of a circular arc which are made of flexible materials; the lower shim block is arranged the crown face of the lower gripping head; a convex rib is formed on the outer cambered surface of the upper shim block in the axial direction; and the convex rib formed on the upper shim block is arranged at the crotch of the lower end of the upper gripping head. By adopting the gripping head, the neck journal damage caused by the gripping head when the roller is replaced can be avoided effectively, the service life of the roller is prolonged, and the production cost is lowered.
Description
Technical field
The utility model relates to a kind of chuck of Multi-Roll Cluster Mill Changing Gear.
Background technology
Adopt changing rig to realize that the gripping of roll changes in the multi-roll mill of metallurgy industry, changing rig is generally by being positioned at up and down base of the carrier head of roll pins having, being installed on chuck on the base of the carrier head and base of the carrier head drive unit etc. and forming; When milling train needs roll change, drive unit at first along roll mandrel to driving up and down base of the carrier head to the roll pins having position, but the upper grip seat by the wedge type block upper and lower displacement, drive unit drives chuck and clamps roll and realize roll change then; But the chuck of existing changing rig is a rigidity, and is inaccurate or in clamping force and add under the effect of impulsive force, the chuck breaker roll axle journal of rigidity causes damage, has influenced the service life of roll, has increased production cost when chuck and roll contraposition.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of chuck of Multi-Roll Cluster Mill Changing Gear, and the roll pins having damage of using this chuck can effectively avoid roll to be caused by chuck when changing has prolonged roll service life, has saved production cost.
For solving the problems of the technologies described above, the chuck of the utility model Multi-Roll Cluster Mill Changing Gear, described chuck comprises upper grip and lower chuck, described lower chuck is one rectangular, described rectangular face towards roll is arc surface, described lower chuck one end connects the lower chuck seat, described upper grip is the rectangular block of a lower end bifurcated, the upper end of described upper grip connects the upper grip seat, also comprise cushion block on the circular arc lower cushion block made by flexible material and the circular arc, described lower cushion block is located on the arc surface of described lower chuck, and described upward cushion block is provided with protruding stupefied vertically at extrados, the described protruding stupefied crotch of being located at described upper grip lower end of going up cushion block.
Above-mentioned lower cushion block can be connected by bolt with lower chuck, and the above-mentioned protruding stupefied and upper grip of going up cushion block can be connected by bolt.
The flexible material of above-mentioned making lower cushion block and last cushion block is nylon or elastomeric material.
Because the chuck of the utility model Multi-Roll Cluster Mill Changing Gear has adopted technique scheme, the upper and lower cushion block of being made by flexible material promptly is set respectively on the upper and lower chuck of former changing rig, so when roll is changed, what the chuck of changing rig contacted with roll is upper and lower cushion block, both can under the effect of clamping force, clamp roll, can slow down the friction of changing rig chuck and roll pins having again, effectively protect roll pins having; The roll pins having damage of using this chuck can effectively avoid roll to be caused by chuck when changing has prolonged roll service life, has saved production cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the utility model Multi-Roll Cluster Mill Changing Gear chuck.
The specific embodiment
As shown in Figure 1, the chuck of the utility model Multi-Roll Cluster Mill Changing Gear, described chuck comprises lower chuck 4 and upper grip 5, described lower chuck 4 is one rectangular, described rectangular face towards roll 1 is arc surface, described lower chuck 4 one ends connect lower chuck seat 2, described upper grip 5 is rectangular blocks of a lower end bifurcated, the upper end of described upper grip 5 connects upper grip seat 3, also comprise cushion block 7 on the circular arc lower cushion block 6 made by flexible material and the circular arc, described lower cushion block 6 is located on the arc surface of described lower chuck 4, and the described cushion block 7 of going up is provided with protruding stupefiedly 8 vertically at extrados, describedly go up the crotch that protruding stupefied 8 of cushion block 7 is located at described upper grip 5 lower ends.
Above-mentioned lower cushion block 6 can be connected by bolt with lower chuck 4, and above-mentioned protruding stupefied 8 of the cushion block 7 of going up can be connected by bolt with upper grip 5.
The flexible material of above-mentioned making lower cushion block 6 and last cushion block 7 is nylon or elastomeric material.
The chuck of the utility model Multi-Roll Cluster Mill Changing Gear is provided with the upper and lower cushion block of being made by flexible material respectively on the upper and lower chuck of former changing rig, so when roll is changed, what the chuck of changing rig contacted with roll is upper and lower cushion block, both can under the effect of clamping force, clamp roll, can slow down the friction of changing rig chuck and roll pins having again, effectively protect roll pins having; The roll pins having damage of using this chuck can effectively avoid roll to be caused by chuck when changing has prolonged roll service life, has saved production cost.
