Abstract
The utility model discloses an expansion mechanism, in particular to the expansion mechanism of core shaft of uncoiler. The expansion mechanism of the core shaft of the uncoiler comprises an oil cylinder, the core shaft which is fixedly connected with the oil cylinder, a core shaft sleeve body, gears, vertical racks, horizontal racks and expansion bodies, the core shaft is inserted in the core shaft sleeve body, the horizontal racks are fixed on the core shaft, the gears are arranged above the horizontal racks to be meshed with the horizontal racks, each vertical rack is arranged on one side of each gear and meshed with the gear, the expansion bodies are fixed at the upper ends of the horizontal racks; the number of the horizontal racks, the gears and the vertical racks are the same and above two; and the gears are fan-shaped gears. The expansion mechanism has the advantages that a material roll is rapidly tightened under the action of expansion force by the expansion of the expansion body.
Description
Technical field
The utility model relates to a kind of expanding mechanism, particularly a kind of decoiling unit mandrel expanding mechanism.
Background technology
At present, in machinery manufacturing industry, especially in auto manufacturing, the coiled strip of all size all needs the uncoiling rolling, and in the process of uncoiling and rolling, the material volume all needs by tensioner, existing tensioner mode is to be provided with one to carve son in the center sky of material volume, when needs are rolled up tensioner to material, promote to carve son and advance, thereby will expect the volume tensioner, but, owing to carve son in the process of advancing, have the component of horizontal direction, so the tensioner poor effect.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of and can automatically material be rolled up the decoiling unit mandrel extension fixture of tensioner.
In order to solve the problems of the technologies described above, decoiling unit mandrel expanding mechanism of the present utility model, comprise oil cylinder, the mandrel of captiveing joint, mandrel body, gear, vertical tooth bar, horizontal rack and expansion body with oil cylinder, described mandrel is inserted in the mandrel body, described horizontal rack is fixed on the mandrel, described gear is located at the top of horizontal rack and is meshed with horizontal rack, and described vertical tooth bar is located at a side of gear and is meshed with gear, and described expansion body is fixed on the upper end of horizontal rack.
Decoiling unit mandrel expanding mechanism of the present utility model, the quantity of described horizontal rack, gear and vertical tooth bar is identical, is more than two.
Decoiling unit mandrel expanding mechanism of the present utility model, described gear is a quadrant gear.
The beneficial effect that the utility model is obtained is: by the expansion of expansion body, under the effect of expansionary force, fast speed will be expected the volume tensioner.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, vertical tooth bar, 2, gear 3, horizontal rack, 4, expansion body, 5, mandrel, 6, oil cylinder, 7, the mandrel body, 8, piston rod.
The specific embodiment
As shown in Figure 1, piston rod 8, the mandrel 5 of captiveing joint, mandrel body 7, gear 2, vertical tooth bar 1, horizontal rack 3 and the expansion body 4 that comprises that oil cylinder 6, oil cylinder are provided with of the present utility model with piston rod 8, described mandrel 5 is inserted in the mandrel body 7, described horizontal rack 3 is fixed on the mandrel 5, described gear 2 is located at the top of horizontal rack 3 and is meshed with horizontal rack 3, described vertical tooth bar 1 is located at a side of gear 2 and is meshed with gear 2, and described expansion body 4 is fixed on the upper end of horizontal rack 3; The quantity of described horizontal rack 3, gear 2 and vertical tooth bar 1 is identical, is four; Described gear 2 is a quadrant gear.
When material need be rolled up tensioner, horizontal motion is done in piston rod 8 beginnings that at first are oil cylinder 6 left, because piston rod 8 is captiveed joint with mandrel 5, so mandrel 5 begins along horizontal direction to left movement, under the drive of mandrel 5, be fixed on the mandrel 5 horizontal rack 3 also along horizontal direction to left movement, because horizontal rack 3 is meshed with gear 2, at this moment, under the driving of horizontal rack 3, gear 2 is done and is clockwise rotated, and gear 2 is when rotating, because gear 2 is meshed with vertical tooth bar 1, so can drive vertical tooth bar 1 upward movement, and expansion body 4 is captiveed joint with vertical 1 in tooth, so expansion body 4 is also with regard to upward movement, expansion body 4 is promptly finished the tensioner to the material volume in the process of upward movement.
