Description

Technical Field

[0001] This utility model relates to an overlap and side clearance adjustment mechanism for an aluminum sheet and strip disc shearing device, and belongs to the field of aluminum sheet and strip disc shearing technology. Background Technology

[0002] In the finishing process of aluminum sheet and strip, the rotary shear is a key slitting and cutting device. Its core function is to accurately cut wide aluminum coils into multiple narrow strips of the required width. The cutting quality of the rotary shear (such as cut perpendicularity, burr size, and edge flatness) and the life of the cutter directly depend on two crucial process parameters: overlap and side clearance. For a long time, traditional aluminum sheet and strip rotary shear equipment has generally adopted manual adjustment for the overlap and side clearance. This usually relies on operators manually rotating multiple large handwheels, lead screws, or worm gear mechanisms to drive the cutter shaft or cutter holder to move its position. The adjustment mechanism is primitive, the adjustment process is cumbersome, time-consuming, and inefficient.

[0003] To address the above technical issues, this paper proposes an overlap and side clearance adjustment mechanism for an aluminum sheet and strip disc shearing device. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an overlap and side clearance adjustment mechanism for an aluminum plate and strip disc shearing device.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an overlap and side clearance adjustment mechanism for an aluminum plate and strip disc shearing device, including a frame, on which an active rotation adjustment component and a passive rotation adjustment component driven by a first electric component are provided. Both the active and passive rotation adjustment components are eccentrically mounted with a cutter shaft for mounting a disc cutter. The passive rotation adjustment component is also connected to a second electric component to facilitate the axial reciprocating movement of the passive rotation adjustment component to adjust its position.

[0006] Preferably, the active rotation adjustment component includes an active gear driven to rotate by a first servo motor, and the driven rotation adjustment component includes a driven gear, with the active and driven gears meshing with each other.

[0007] Preferably, eccentric sleeves are eccentrically fixedly connected to the end faces of both the driving and driven gears, and the cutter shaft is coaxially installed inside each eccentric sleeve.

[0008] Preferably, a first bearing is coaxially mounted between the cutter shaft and the eccentric sleeve.

[0009] Preferably, the disc cutter is coaxially mounted on the exposed outer end of the cutter shaft.

[0010] Preferably, the second electric component includes a second servo motor, which is connected to the driven rotary adjustment component via a ball screw pair.

[0011] Preferably, the ball screw assembly includes a screw coaxially fixedly connected to the output shaft of the second servo motor, and a ball nut is coaxially screwed onto the screw.

[0012] Preferably, a second bearing is coaxially mounted on the outer periphery of the eccentric sleeve of the driven rotation adjustment assembly. The axial degree of freedom of the second bearing on the eccentric sleeve of the driven rotation adjustment assembly is limited, and an adapter is fixedly connected to the outer ring of the second bearing.

[0013] Preferably, the adapter has a first through hole with an inner diameter larger than the outer diameter of the lead screw, and the end of the lead screw passes through the first through hole.

[0014] Preferably, a screw is locked on the end face of the adapter, and the connecting flange of the ball nut is provided with a second through hole with an inner diameter larger than the outer diameter of the external thread section of the screw and smaller than the outer diameter of the nut head of the screw. The external thread section of the screw passes through the second through hole so that the connecting flange is located between the nut head of the screw and the adapter.

[0015] Compared with the prior art, the present invention has the following advantages: the overlap amount and side clearance adjustment mechanism of the aluminum plate strip disc shearing device adopts electric adjustment and eccentric setting to realize the adjustment of the overlap amount, and adopts electric adjustment and axial movement to realize the adjustment of the side clearance, replacing the traditional manual adjustment. The adjustment process is simple, fast, efficient and effective.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] like Figures 1-3 As shown, this embodiment provides an overlap and side clearance adjustment mechanism for an aluminum sheet and strip disc shearing device, including a frame 1. The frame is equipped with an active rotation adjustment component and a passive rotation adjustment component driven by a first electric component. Both the active and passive rotation adjustment components are eccentrically mounted with a cutter shaft 3 for mounting a disc cutter 2. The passive rotation adjustment component is also connected to a second electric component to facilitate the axial reciprocating movement of the passive rotation adjustment component to adjust its position.

[0025] In this embodiment of the utility model, the active rotation adjustment component includes an active gear 5 driven to rotate by a first servo motor 4, and the driven rotation adjustment component includes a driven gear 6. The active and driven gears mesh with each other, and the first servo motor is a first electric component.

[0026] In this embodiment of the utility model, an eccentric sleeve 7 is eccentrically fixedly connected to the end face of both the driving and driven gears, and the cutter shaft is coaxially installed inside the eccentric sleeve.

[0027] In this embodiment of the utility model, a first bearing 8 is coaxially installed between the cutter shaft and the eccentric sleeve.

[0028] In this embodiment of the invention, the disc cutter is coaxially mounted on the exposed outer end of the cutter shaft.

[0029] In this embodiment of the present invention, the second electric component includes a second servo motor 9, and the second servo motor is connected to the driven rotary adjustment component via a ball screw pair.

[0030] In this embodiment of the utility model, the ball screw pair includes a screw 10 coaxially fixedly connected to the output shaft of the second servo motor, and a ball nut 11 is coaxially screwed onto the screw.

[0031] In this embodiment of the present invention, a second bearing 12 is coaxially mounted on the outer periphery of the eccentric sleeve of the driven rotation adjustment component. The axial degree of freedom of the second bearing on the eccentric sleeve of the driven rotation adjustment component is limited, and an adapter 13 is fixedly connected to the outer ring of the second bearing.

[0032] In this embodiment of the utility model, the adapter has a first through hole 14 with an inner diameter larger than the outer diameter of the lead screw, and the end of the lead screw passes through the first through hole; a screw 15 is locked on the end face of the adapter, and the connecting flange 16 of the ball nut has a second through hole 17 with an inner diameter larger than the outer diameter of the external thread section of the screw and smaller than the outer diameter of the nut head of the screw. The external thread section of the screw passes through the second through hole so that the connecting flange is located between the nut head of the screw and the adapter.

[0033] In this embodiment of the invention, a sliding block slide rail moving pair connects the ball nut and the frame, so that when the lead screw rotates, the ball nut does not rotate but reciprocates axially, driving the adapter to move together. Specifically, the nut head of the screw does not press the connecting flange tightly onto the adapter. When adjusting the overlap, the adapter will slightly sway within a predetermined range along with the eccentric sleeve. At this time, the first through hole will not touch the lead screw, thus avoiding interference with the lead screw, and the screw will not touch the second through hole, thus avoiding interference between the screw and the connecting flange.

[0034] A method for adjusting the overlap and side clearance of an aluminum sheet and strip disc shearing device, comprising the following steps: S1: The first servo motor drives the active gear to rotate, the active gear drives the driven gear to rotate, and the rotation of the active and driven gears drives the eccentric sleeve fixed on them to rotate eccentrically, so as to facilitate the adjustment of the overlap A between the two disc cutters. S2: After the overlap adjustment is completed, the second servo motor drives the lead screw to rotate. The ball nut screwed on the lead screw drives the adapter to move back and forth along the axis for adjustment. The adapter drives the eccentric sleeve of the driven rotary adjustment component to move through the second bearing. During the movement of the eccentric sleeve of the driven rotary adjustment component, the main and driven gears are misaligned and meshed, and the side clearance B between the two disc cutters is adjusted.

[0035] In step S2, both the driving and driven gears are relatively thick. During backlash adjustment, the driven gear is allowed to move axially relative to the driving gear, as long as the meshing of the driving and driven gears does not disengage.

[0036] In step S1, after the overlap between the two disc cutters is adjusted, a first hydraulic cylinder 18 is fixedly connected to the frame. The first hydraulic cylinder drives the piston rod to press against the end of the drive gear with an appropriate force, so as to keep the drive gear from rotating.

[0037] In step S2, after the side clearance between the two disc cutters is adjusted, a second hydraulic cylinder 19 is fixedly connected to the frame. The second hydraulic cylinder drives the piston rod to press against the outer periphery of the eccentric sleeve of the driven rotary adjustment assembly with an appropriate force, so as to keep the axial position of the eccentric sleeve of the driven rotary adjustment assembly unchanged.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
