Abstract
The utility model mainly relates to a lifting device for a pinch roll, which belongs to auxiliary devices of nonferrous metal finishing equipment. The lifting device mainly comprises a frame (1), an upper roll (2), a lower roll (7), sliding plates and an oil cylinder (12). The upper roll (2) is positioned inside an upper bearing seat (3) and enables the upper bearing seat (3) to be connected with the frame (1) together; the lower roll (7) is positioned inside a lower bearing seat (8) and is connected with a lower oil cylinder (12) positioned below the lower bearing seat; the oil cylinder (12) is fixed on the frame (1); the sliding plates include four sliding plates A (5) fixed on the corresponding slide tracks and two sliding plates B (14) fixed on the lower bearing seat (8). The lifting device provided by the utility model has the characteristics of simple structure and convenient installation, debugging and dismounting. The device operates through the reciprocating movement of the oil cylinder, with low required stroke of the oil cylinder, and the parallelism of the lower roll and the upper roll is easy to ensure, so as to ensure the surface quality of strips.
Description
Technical field
The utility model belongs to the servicing unit of non-ferrous metal finishing equipment, relates generally to a kind of pinch roll lowering or hoisting gear.
Background technology
In re-reeler or stretch bending-straightening machine, the pinch roll lowering or hoisting gear is to introduce stub bar from last single devices, after the pinch roll lower roll rises, revolution on the lower roll makes pinch roll pinch band and enters next single devices by this device, draw the material finish after, the pinch roll lower roll descends, pinch roll surface encapsulate; Its effect mainly is to grind head and guiding feeding.The pinch roll lowering or hoisting gear mostly is that top roll is fixed at present, and lower roll is a movable roll.Lower roll is fixed in the swing arm, promotes swing arm drive lower roll by middle cylinders and puts, and this structure not only requires the stroke of cylinder long, and is difficult to when mounted guarantee the depth of parallelism of two rollers up and down, and this will badly influence the surface quality of band.This structure is being installed, is being debugged and dismantling all cumbersome in addition.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to propose a kind of pinch roll lowering or hoisting gear, copper shoe is housed does guiding, and is more simple and convenient in installation, debugging and dismounting, thereby overcomes the existing in prior technology deficiency.
Adopt following technical scheme for finishing its invention task the utility model:
A kind of pinch roll lowering or hoisting gear mainly comprises frame, top roll, lower roll, slide plate and oil cylinder; Described top roll is positioned at top chock, and top chock and frame are connected as a single entity; Described lower roll is positioned at step, and connects with oil cylinder by the connected body that is positioned at the step below; Described oil cylinder is fixed on the frame; Described slide plate is two kinds, corresponding each slide plate is provided with slideway on frame, slideway cooperates with slide clearance, wherein a kind of slide plate is four and is symmetrical arranged in twos, four slide plates are separately fixed on the slideway corresponding with it, another kind of slide plate is two and is symmetrical arranged that two slide plates are fixed on the step.
Its below of described step has a square opening, and is connected as a single entity by the coupling ring in the square opening and bearing pin and connected body.
A kind of pinch roll lowering or hoisting gear that the utility model proposes, it has simple in structure, the characteristics of installation, debugging and convenient disassembly; This device is the reciprocating motion of oil cylinder, and required oil cylinder stroke is short, and the depth of parallelism of lower roll and top roll is easy to assurance, thereby has guaranteed the surface quality of band.

Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, 1, frame, 2, top roll, 3, top chock, 4, bolt, 5, slide plate A, 6, screw, 7, lower roll, 8, step, 9, coupling ring, 10, bearing pin, 11, connected body, 12, oil cylinder, 13, the articulation hole bolt, 14, slide plate B.
The specific embodiment
The embodiment that provides in conjunction with the accompanying drawings is illustrated the utility model:
As shown in Figure 1, 2, a kind of pinch roll lowering or hoisting gear mainly comprises frame 1, top roll 2, lower roll 7, slide plate and oil cylinder 12; Described top roll 2 is positioned at top chock 3, and top chock 3 is fixed on the frame 1 by bolt 4; Described lower roll 7 is positioned at step 8, and step 8 bottoms have square opening, and coupling ring 9 places in the square opening, and connected body 11 links to each other with step 8 by coupling ring 9 and bearing pin 10, and connected body 11 connects with oil cylinder 12 by screw thread.Oil cylinder 12 is fixed on the frame 1 with bolt 13 by articulation hole.Described slide plate is two kinds, corresponding each slide plate is provided with slideway on frame, slideway cooperates with slide clearance, wherein a kind of slide plate A5 is four and is symmetrical arranged in twos, four slide plates are separately fixed on the slideway corresponding with it, another kind of slide plate B14 is two and is symmetrical arranged that two slide plates are fixed on the step.Oil cylinder 12 promotion steps 8 slide on slide plate A5 and drive lower roll 7 ascending motions.
Claims (2)
1. a pinch roll lowering or hoisting gear is characterized in that: mainly comprise frame (1), top roll (2), lower roll (7), slide plate and oil cylinder (12); Described top roll (2) is positioned at top chock (3), and top chock (3) and frame (1) are connected as a single entity; Described lower roll (7) is positioned at step (3), and connects with oil cylinder (12) by the connected body (11) that is positioned at the step below; Described oil cylinder (12) is fixed on the frame (1); Described slide plate is two kinds, corresponding each slide plate is provided with slideway on frame, slideway cooperates with slide clearance, wherein a kind of slide plate A (5) is four and is symmetrical arranged in twos, four slide plates are separately fixed on the slideway corresponding with it, another kind of slide plate B (14) is two and is symmetrical arranged that two slide plates are fixed on the step (8).
