Description

Deburring mechanism of aluminum strip splitting machine

Technical Field

The utility model relates to an equipment technical field is cut to the aluminium book, especially relates to a burring mechanism of aluminium strip cutting machine.

Background

The aluminum strip can be coiled into a mother coil with wider width after being rolled and formed so as to be supplied to various industries for use. In the new energy battery industry, the shell, utmost point ear etc. of battery all need use aluminium sheet, and this just need divide into the aluminium strip of different width and rewind the book with great mother according to the size of needs to supply follow-up continuous production to use, because the battery security requires highly, therefore the aluminium strip is cut the quality requirement and is also high, and bad such as burr can not appear in the edge. When the existing aluminum coil slitting equipment is used for slitting, a mother aluminum coil is slit by a slitting knife shaft and then sent to a tension winding shaft for rewinding through reversing of a guide roller, and due to certain fluctuation of winding tension, the situation that the tightness of the aluminum coil is changed at the shearing point of the slitting knife shaft is caused, so that the edge of the sheared aluminum coil is poor in burrs; in addition, because the cut aluminum strips are obliquely arranged between the slitting knife shaft and the guide roller, the edges of the cut aluminum strips can be abutted against the side walls of the annular slitting knives of the slitting knife shaft, the edges of the aluminum strips and the side walls of the slitting knives rub with each other, and when the material strips slightly swing in the winding process, the side walls of the slitting knives can extrude the edges of the aluminum strips into a wavy shape, so that the aluminum strips are not good; both of these conditions make it difficult for the slit aluminum ribbon to meet the quality requirements of the battery product.

Detailed Description

The invention is further explained below with reference to the drawings:

referring to fig. 1 to 3, a deburring mechanism for an aluminum strip splitting machine comprises a frame 1, two splitting cutter shafts 2 arranged on the frame 1 in parallel and tangentially, two guide rollers 3 arranged on the frame 1 in parallel for guiding the split aluminum strips to two sides in a staggered manner, a winding shaft 4 for winding the split aluminum strips, and a tension adjusting device 5 arranged between the guide rollers 3 and the winding shaft 4; the tension adjusting device 5 comprises a mounting frame 52 with one end hinged on the frame 1 and the other end driven by a lifting driving device 51 to lift, and a plurality of guide rollers 53 which are arranged in parallel and are arranged on the mounting frame 52 in a rolling way; the mounting frame 52 is further provided with a mounting rod 6 parallel to the guide roller 53, two sides of each aluminum strip corresponding to the mounting rod 6 are respectively provided with an edge trimming device 7, and the edge trimming devices 7 comprise two guide wheels 71 which are arranged in an up-down symmetrical mode and used for clamping the edges of the aluminum strips.

When the aluminum strip splitting machine works, a wider aluminum strip mother coil is fed into the splitting cutter shaft 2 to be split, a plurality of groups of splitting cutters with the same axle center are axially arranged on the splitting cutter shaft 2 according to the width size to be split, and the splitting cutters of the two splitting cutter shafts 2 correspond to each other pairwise to form a shearing point; the mother tape is divided into a plurality of narrow-edge aluminum tapes and then guided to two sides in a staggered direction, so that a gap space is formed between two adjacent aluminum tapes on the same side, the trimming mechanism is convenient to install, the whole tension on two sides of the aluminum tapes can be guaranteed to be balanced when the aluminum tapes are cut, and the phenomenon that the cutting quality is influenced due to unbalanced stress on two axial ends of the slitting cutter shaft 2 is avoided. When the cut aluminum strip passes through the trimming device 7, the two sides of the aluminum strip are clamped by the upper guide wheel 71 and the lower guide wheel 71, so that burrs at the edge of the aluminum strip can be removed, and the wavy poor leveling caused by shearing can be realized, thereby achieving the required aluminum strip cutting quality.

In this embodiment, the opposite surfaces of the two guide wheels 71 are in an angle shape which is opened towards one side of the aluminum strip. More specifically, the trimming device 7 further includes a mounting block 72 extending laterally from the mounting rod 6, and two fixing rods 73 fixed to the mounting block 72 and located on axial lines of the two guide wheels 71, and the guide wheels 71 are mounted on the fixing rods 73 through bearing sleeves. When guide pulley 71 is the contained angle setting, can produce bigger pressure to aluminium strip outside border, can not only get rid of the burr, but also can be with the aluminium strip because of the sharp border that the shearing leads to with the mode of chamfer whole smooth.

In this embodiment, the mounting bar 6 is located on the side of the mounting frame 52 adjacent to the guide roller 3. At the moment, the trimming device 7 is close to one side of the guide roller 3, the aluminum strip just comes out from the slitting knife shaft 2, and the left-right deflection amplitude is smaller relative to one side of the winding shaft 4, so that the trimming devices 7 on two sides of the aluminum strip are stressed more uniformly, and the situation that the trimming is not in place due to the fact that the extrusion force on one side of the aluminum strip is too large and the trimming on the other side of the aluminum strip is not in place can be avoided.

In this embodiment, the reversing lines of the two guide rollers 3 are both located on the tangent lines of the two slitting knife shafts 2. The tangent line of the slitting cutter shaft 2 at the shearing point is the same tangent line, and the line parallel to the axis of the guide roller 3, which is formed at the position where each slit aluminum strip contacts the guide roller 3, is the reversing line. The switching-over line of guide roll 3 is located the tangent line of branch cutter shaft 2, and at this moment, the aluminium strip cuts the back from the cutting edge department of dividing cutter shaft 2 and extends to guide roll 3 switching-over again along tangent line, and the aluminium strip edge after consequently cutting can not support the branch cutter lateral wall that contacts branch cutter shaft 2, even the aluminium strip has slight beat at the rolling in-process, can not force the wavy turn-up to appear in the edge yet, has further improved the quality of cutting.

In this embodiment, the tangent lines of the two slitting cutter shafts 2 are vertically arranged, the two guide rollers 3 are located at the same side position above or below the slitting cutter shafts 2, and the axes of the two guide rollers 3 are vertically staggered. Two when the axis of guide roll 3 staggers the setting vertically, compare the structure that sets up side by side, the switching-over line department of two guide rolls 3 can not cause the extrusion for the aluminium strip after being cut can not only keep vertical upward straightening, avoids aluminium strip and branch cutter lateral wall contact, can avoid two guide rolls 3 to extrude the aluminium strip because of the distance is too near moreover, causes the aluminium strip to convey the difficulty.

The above description is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
