Description

Technical Field

[0001] The utility model belongs to the technical field of coil material processing equipment and relates to a coil material burr straightening mechanism. Background Art

[0002] The width of the metal coils produced by the steel rolling mill is very large, which does not meet the width of the metal coils required by the buyers. Therefore, it is necessary to cut the wider metal coils into several smaller metal strips according to the buyers' needs.

[0003] The edges of the metal coils produced by the steel rolling mill are rough and not straight, so they cannot be used as a reference for slitting. They need to be corrected by gravity, and gravity correction requires digging deep pits. Workers will dig one or more deep pits between the coil and the cutting machine. The pulled coil will first sink into the deep pit. The coil will be straightened by its own weight without the help of other external forces. The straightened coil will then go deep into the cutting machine for cutting, which can ensure that the cut metal strip is straight. However, this straightening method by digging deep pits not only occupies a large area, but also requires the original deep pit to be buried when changing the site, and a new deep pit must be dug at the new site, which is time-consuming and labor-intensive.

DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figure 1As shown, a mechanism for straightening the rough edges of a coil of material described in the utility model comprises a frame 1, a rotating shaft 20 horizontally rotatably arranged on the frame 1, and a coil of material 2 sleeved on the rotating shaft 20. The frame 1 is also provided with a cutting assembly, which is mounted on the frame 1 through a floating frame. The floating frame comprises a floating base and a plurality of detection wheel groups movably arranged on the floating base. The plurality of detection wheel groups are arranged at intervals along the circumference of the coil of material 2. The floating base can move or swing in multiple directions so that the outer wheel surface of each detection wheel group always rests against the outer wheel surface of the coil of material 2. The cutting assembly moves synchronously with the detection wheel groups, and the head of the coil of material 2 extends into the cutting assembly for fixed-width cutting.

[0024] like Figures 2 to 4 As shown, the floating base includes a fixed seat 3, a movable seat 4, a horizontal plate 5, a vertical plate 6, and a telescopic rod 7. The number of the telescopic rods 7 corresponds to the number of the detection wheel groups. Each detection wheel group is slidably arranged on the corresponding telescopic rod 7, and the telescopic rod 7 is provided with a radial translation driving member for driving the detection wheel group to translate radially along the rotating shaft 20; each telescopic rod 7 is fixed on the vertical plate 6, the vertical plate 6 is horizontally rotatably arranged on the horizontal plate 5, the horizontal plate 5 is vertically rotatably arranged on the movable seat 4, and the movable seat 4 is provided with a rotating driving member for driving the horizontal plate 5 to rotate; the movable seat 4 is axially and horizontally slidably arranged on the fixed seat 3 along the rotating shaft 20, and the fixed seat 3 is provided with an axial translation driving member for driving the movable seat 4 to translate back and forth.

[0025] When the floating frame is in a free and unstressed state, the detection wheel group translates radially along the rotating shaft 20; when the detection wheel 8 abuts against the coil 2, after the position of the floating base is adjusted, the position of the telescopic rod 7 is offset, and the detection wheel group translates radially along the coil 2.

[0026] The moving direction of the movable seat 4 described in the utility model is parallel to the axial direction of the rotating shaft 20, and can also be nearly parallel. Similarly, the moving direction of the detection wheel 8 and the rotation direction of the vertical plate 6 and the horizontal plate 5 are allowed to have errors within a certain range, and through coordinated adjustment in multiple directions, the outer wheel surface of each detection wheel group is always in contact with the outer wheel surface of the coil 2.

[0027] When in use, the coil 2 rotates one circle, and the floating base adjusts its position so that the outer wheel surface of each detection wheel group is adjusted to abut against the outer wheel surface of the coil 2. At this time, the positions of the movable seat 4, the horizontal plate 5 and the vertical plate 6 remain stationary, the coil 2 continues to rotate, and the outer diameter of the coil 2 continues to decrease. The radial translation drive member on the telescopic rod 7 drives the detection wheel group to translate radially along the coil 2. During the rotation of the coil 2, the outer wheel surface of each detection wheel group is always abutted against the outer wheel surface of the coil 2.

[0028] like Figure 5As shown, the detection wheel group includes two detection wheels 8, which are arranged axially at intervals along the rotating shaft 20; the detection wheel group is arranged on the telescopic rod 7 through a fixed width mechanism, and the fixed width mechanism is used to adjust the spacing between the two detection wheels 8. The fixed width mechanism includes a fixed plate 9 and a movable plate 10, and the two movable plates 10 are axially slidably arranged on the fixed plate 9 along the rotating shaft 20. The fixed plate 9 is provided with two fixed width driving members to drive the two fixed plates 9 to translate respectively, and the two detection wheels 8 are rotatably arranged on the corresponding movable plates 10.

[0029] There are two groups of cutting components, which are arranged on both sides of the coil 2. The cutting components include a knife seat 11, an active knife disc 12 and a driven knife disc 13 rotatably arranged on the knife seat 11, and a knife disc driving member driving the active knife disc 12 to rotate. The active knife disc 12 and the driven knife disc 13 are correspondingly engaged up and down to form a cutting position. The cutting component is fixedly connected to the detection wheel group near the head of the coil 2, and the knife seat 11 on the cutting component is fixedly connected to the movable plate 10 on the detection wheel group; the two fixed width driving members on the detection wheel group respectively drive the two movable plates 10 to translate, and correspondingly drive the detection wheel 8 and the cutting component to translate synchronously.

[0030] like Figure 3 As shown, the rotation centerline of the horizontal plate 5 is vertically arranged and intersects with the centerline of the coil 2; in a free and unstressed state, the axis of the detection wheel 8 on the detection wheel group close to the head of the coil 2 coincides with the axis of the rotating shaft 20 on the horizontal plane. There are two detection wheel groups, and on the vertical plane, the angle between the center of the two detection wheel groups and the center of the rotating shaft 20 is an acute angle or a right angle.

[0031] The radial translation driving component includes a screw rod 1 rotatably set on the telescopic rod 7, a nut 1 fixedly connected to the fixed plate 9, and a radial translation motor 14 that drives the screw rod 1 to rotate; the rotating driving component includes a rotating motor 15 fixedly set on the movable seat 4, and the output shaft of the rotating motor 15 is fixedly connected to the cross plate 5; the axial translation driving component includes a screw rod 2 rotatably set on the fixed seat 3, a nut 2 fixedly connected to the movable seat 4, and an axial translation motor 16 that drives the screw rod 2 to rotate; the cutter disc driving component includes a cutter disc motor 17 fixedly set on the cutter seat 11, and the output shaft of the cutter disc motor 17 is transmission-connected to the active cutter disc 12; the fixed-width driving component includes a screw rod 3 rotatably set on the fixed plate 9, a nut 3 fixedly connected to the movable plate 10, and a fixed-width motor 18 that drives the screw rod 3 to rotate.
