Description

Technical Field

[0001] The present invention relates to an overlapping amount and side clearance adjustment mechanism and method for an aluminum sheet and strip circular shearing device, and relates to the technical field of aluminum sheet and strip circular shearing technology. Background Art

[0002] In the finishing process of aluminum sheet and strip materials, a circular shear is a key longitudinal slitting equipment, and its core function is to accurately slit a wide aluminum coil into multiple narrow strips with widths meeting customer requirements. The shearing quality (such as the perpendicularity of the cut, the size of burrs, and the flatness of the edge) and the tool life of the circular shear directly depend on two crucial process parameters: the overlapping amount and the side clearance. For a long time, in the adjustment of the overlapping amount and side clearance of traditional aluminum sheet and strip circular shear equipment, a manual adjustment method is generally adopted. Usually, an operator manually rotates multiple large handwheels, lead screws or worm and worm gear mechanisms to drive the tool shaft or tool holder to move in position. The adjustment mechanism is primitive, the adjustment process is cumbersome and time-consuming, and the efficiency is low.

[0003] To solve the above technical problems, this case proposes an overlapping amount and side clearance adjustment mechanism and method for an aluminum sheet and strip circular shearing device. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an overlapping amount and side clearance adjustment mechanism and method for an aluminum sheet and strip circular shearing device.

[0005] To solve the above technical problems, the technical solution of the present invention is: An overlapping amount and side clearance adjustment mechanism for an aluminum sheet and strip circular shearing device, including a frame, on which an active rotation adjustment component and a driven rotation adjustment component driven by a first electric component are arranged. On both the active and driven rotation adjustment components, a tool shaft for installing a circular cutter is eccentrically installed. A second electric component is also connected to the driven rotation adjustment component to facilitate the driven rotation adjustment component to move back and forth along the axial direction to adjust the position.

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

[0007] Preferably, eccentric sleeves are eccentrically and fixedly connected to the end faces of both the active and driven gears, and the tool shafts are coaxially installed inside the eccentric sleeves.

[0008] Preferably, first bearings are coaxially installed between the tool shafts and the eccentric sleeves.

[0009] Preferably, the circular cutter is coaxially installed at the exposed outer end of the tool shaft.

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

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

[0012] Preferably, a second bearing is coaxially installed on the outer peripheral portion of the eccentric sleeve of the driven rotary adjustment component, the axial degree of freedom of the second bearing on the eccentric sleeve of the driven rotary adjustment component is limited, and a transfer member is fixedly connected to the outer ring of the second bearing.

[0013] Preferably, a first through hole with an inner diameter larger than the outer diameter of the screw is formed in the transfer member, and the end of the screw penetrates into the first through hole; a screw is locked on the end face of the transfer member, and 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 is provided on the connecting flange of the ball nut, and 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 transfer member.

[0014] A method for adjusting the overlap amount and side clearance of an overlap amount and side clearance adjustment mechanism of an aluminum plate strip circular shearing device is carried out according to the following steps: S1: The first servo motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, and the rotation of the driving and driven gears drives the eccentric sleeve fixedly connected thereto to eccentrically swing, so as to facilitate the adjustment of the overlap amount between the two circular knives; S2: After the overlap amount adjustment is completed, the second servo motor drives the screw to rotate, the ball nut screwed on the screw drives the transfer member to reciprocate axially for adjustment, the transfer member drives the eccentric sleeve of the driven rotary adjustment component to move through the second bearing, and during the movement of the eccentric sleeve of the driven rotary adjustment component, the driving and driven gears are meshed out of position, and the side clearance between the two circular knives is adjusted.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The overlap amount and side clearance adjustment mechanism of the aluminum plate strip circular shearing device adopts an electric adjustment and eccentric setting method to realize the adjustment of the overlap amount, and adopts an electric adjustment and axial movement method to realize the side clearance adjustment, replacing the traditional manual adjustment.

Specific embodiments

[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 description is exemplary and is intended to provide further illustration of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0023] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, 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] As Figures 1 to 3 shown, this embodiment provides an overlap amount and side clearance adjustment mechanism for an aluminum plate strip disc shearing device, including a frame 1. An active rotation adjustment component and a driven rotation adjustment component driven by a first electric component are arranged on the frame. Knife shafts 3 for installing disc cutters 2 are eccentrically installed on both the active and driven rotation adjustment components. A second electric component is also connected to the driven rotation adjustment component to facilitate the reciprocating axial movement of the driven rotation adjustment component to adjust the position.

[0025] In the embodiment of the present invention, the active rotation adjustment component includes a driving gear 5 driven by a first servo motor 4. The driven rotation adjustment component includes a driven gear 6. The driving and driven gears are meshed with each other. The first servo motor is the first electric component.

[0026] In the embodiment of the present invention, eccentric sleeves 7 are eccentrically and fixedly connected to the end faces of both the driving and driven gears. The cutter shafts are coaxially installed inside the eccentric sleeves.

[0027] In the embodiment of the present invention, a first bearing 8 is coaxially installed between the tool shaft and the eccentric sleeve.

[0028] In the embodiment of the present invention, the disc cutter is coaxially installed at the exposed outer end of the tool shaft.

[0029] In the 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 through a ball screw pair.

[0030] In the embodiment of the present invention, the ball screw pair includes a screw rod 10 coaxially and fixedly connected to the output shaft of the second servo motor, and a ball nut 11 is coaxially screwed on the screw rod.

[0031] In the embodiment of the present invention, a second bearing 12 is coaxially installed on the outer peripheral part of the eccentric sleeve of the driven rotary adjustment component. The axial degree of freedom of the second bearing on the eccentric sleeve of the driven rotary adjustment component is limited, and a transfer member 13 is fixedly connected to the outer ring of the second bearing.

[0032] In the embodiment of the present invention, a first through hole 14 with an inner diameter larger than the outer diameter of the screw rod is formed in the transfer member, and the end of the screw rod penetrates into the first through hole; a screw 15 is locked on the end face of the transfer member. A second through hole 17 is provided on the connecting flange 16 of the ball nut, and the inner diameter of the second through hole is 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 transfer member.

[0033] In the embodiment of the present invention, a slider-rail moving pair is connected between the ball nut and the machine frame, so that when the screw rod rotates, the ball nut does not rotate but reciprocates axially and drives the transfer member to translate together. Among them, the nut head of the screw does not press the connecting flange on the transfer member. When adjusting the overlap amount, the transfer member will slightly swing within a predetermined range together with the eccentric sleeve. At this time, the first through hole will not touch the screw rod, and interference with the screw rod can be avoided. The screw will not touch the second through hole, and interference between the screw and the connecting flange can be avoided.

[0034] A method for adjusting the overlap amount and side clearance of an overlap amount and side clearance adjustment mechanism of an aluminum plate strip disc shearing device is carried out according to the following steps: S1: The first servo motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, and the rotation of the driving and driven gears drives the eccentric sleeve fixedly connected thereto to eccentrically swing, so as to adjust the overlap amount A between the two disc cutters; S2: After the overlap amount is adjusted, the second servo motor drives the screw to rotate, and the ball nut screwed on the screw drives the adapter to move back and forth along the axial direction for adjustment. The adapter drives the eccentric sleeve of the driven rotation adjustment component to move through the second bearing. During the movement of the eccentric sleeve of the driven rotation adjustment component, the master and driven gears are staggered and engaged, and the side clearance B between the two disc cutters is adjusted.

[0035] In step S2, the thickness of the driving gear and the driven gear are both relatively thick. When the backlash is adjusted, the driven gear is allowed to move axially relative to the driving gear, as long as the engagement between the driving gear and the driven gear is not disengaged.

[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, and the first hydraulic cylinder drives the piston rod to press the end of the driving gear with appropriate force to help keep the driving 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, and the second hydraulic cylinder drives the piston rod to press the outer periphery of the eccentric sleeve of the driven rotation adjustment assembly with appropriate force, thereby assisting in keeping the axial position of the eccentric sleeve of the driven rotation adjustment assembly unchanged.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other manner. Any person skilled in the art may utilize the above-disclosed technical content to modify or modify the present invention into equivalent embodiments. However, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical content of the present invention and are based on the technical essence of the present invention remain within the scope of protection of the present invention.
