Description

Technical Field

[0001] The utility model belongs to the technical field of coiled material processing equipment and relates to an automatic tape bending device. Background Art

[0002] The width of the metal coiled material produced by a rolling mill is very large and does not meet the width of the metal coiled material required by the purchaser. Therefore, it is necessary to cut the metal coiled material with a large width into multiple metal tapes with a smaller width according to the purchaser's requirements.

[0003] For the cut metal tape, it needs to be wound around a reel. A number of card slots are provided on the outer surface of the reel, and the card slots extend along the axial direction of the reel. Workers manually bend the head of the metal tape to form a hook, and then insert the hook into the card slot of the reel. After the reel rotates, it drives the metal tape to wind.

[0004] For the process of bending the head of the metal tape, it needs to be manually completed by workers, with low work efficiency, low automation level, and time-consuming and laborious. Summary of the Utility Model

[0005] The purpose of the utility model is to address the above problems existing in the winding process of multiple cut metal tapes, and to propose a mechanism that can automatically bend the heads of multiple cut metal tapes.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

The clamping mechanism includes an upper clamping block and a lower clamping block, and there is a material passing gap between the upper clamping block and the lower clamping block. The feeding mechanism feeds the tape into the material passing gap and extends forward out of the material passing gap; the pressing mechanism includes a pressing block and a driving mechanism for driving the pressing block to move. The pressing block moves to abut against the tape and continues to push the tape, and the pressing block presses the tape to bend it, so that the head of the tape is bent to form a hook.

[0008] In the above automatic tape bending device, a pressing surface is provided on the pressing block, and an abutting surface is provided on the clamping mechanism. The driving mechanism drives the pressing block to move towards the clamping mechanism, so that the pressing surface of the pressing block abuts against the tape and continues to push the tape, so that the head of the tape is pressed against the abutting surface to form a hook.

[0009] In the above automatic tape bending device, the clamping mechanism further includes an airbag, and the airbag is located in the material passing gap; after the airbag is inflated, it can fill the material passing gap.

[0010] In the above-mentioned automatic tape bending device, the driving mechanism includes a mounting plate, a lifting cylinder for driving the mounting plate to lift, and a rotating cylinder for driving the pressing block to rotate. The pressing block is rotatably arranged on the mounting plate, and the rotating cylinder is fixedly arranged on the mounting plate and lifts synchronously with the pressing block. The lifting cylinder drives the mounting plate to descend so that the positions of the pressing surface and the abutting surface correspond to each other front and back. The rotating cylinder drives the pressing surface to rotate towards the direction close to the abutting surface so that the pressing surface pushes the head of the tape to be pressed tightly against the abutting surface for bending.

[0011] In the above-mentioned automatic tape bending device, the feeding mechanism includes an upper roller and a lower roller. The upper roller and the lower roller rotate in opposite directions. The tape extends between the upper roller and the lower roller. The upper roller and the lower roller clamp the tape and convey it forward so that the head of the tape is inserted into the above-mentioned material passing gap and extends forward out of the clamping mechanism for the pressing mechanism to bend.

[0012] In the above-mentioned automatic tape bending device, the abutting surface is arranged on the lower clamping block.

[0013] In the above-mentioned automatic tape bending device, both the pressing surface and the abutting surface are inclined slopes so that an acute-angled hook is formed after the head of the tape is bent.

[0014] In the above-mentioned automatic tape bending device, the pressing mechanism and the feeding mechanism are fixedly arranged on the frame. The clamping mechanism is slidably arranged on the frame along the tape conveying direction. A translation mechanism is also arranged on the frame to drive the clamping mechanism to translate.

[0015] In the above-mentioned automatic tape bending device, there is a bending station between the pressing mechanism and the feeding mechanism. The translation mechanism drives the clamping mechanism to move to this bending station. The feeding mechanism feeds the tape into the material passing gap of the clamping mechanism.

Specific embodiments

[0023] The following are specific embodiments of the present utility model and in conjunction with the accompanying drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0024] As Figure 1 shown, an automatic strip bending device of the present utility model includes a frame 2 and a clamping mechanism, a pressing mechanism for bending the strip 1, and a feeding mechanism for feeding the strip 1, which are arranged on the frame 2 and used for clamping the strip 1.

[0025] As Figure 4 shown, the clamping mechanism includes an upper clamping block 20 and a lower clamping block 21, and there is a strip passing gap between the upper clamping block 20 and the lower clamping block 21. The feeding mechanism feeds the strip 1 into the strip passing gap and extends forward outside the strip passing gap; the clamping mechanism further includes an airbag 22, and the airbag 22 is located in the strip passing gap; after the airbag 22 is inflated, it can fill the strip passing gap, and after the airbag 22 is deflated, the strip 1 is inserted into the strip passing gap, and then the airbag 22 is inflated to clamp the strip 1.

[0026] As Figure 2 and Figure 3 shown, the pressing mechanism includes a pressing block 31 and a driving mechanism for driving the pressing block 31 to move. The pressing block 31 moves to abut against the strip 1 and continues to push the strip 1, and the pressing block 31 presses the strip 1 to bend it, so that the head of the strip 1 is bent to form a hook 38. A pressing surface 34 is provided on the pressing block 31, and an abutting surface 35 is provided on the clamping mechanism. The driving mechanism drives the pressing block 31 to move in a direction close to the clamping mechanism, so that the pressing surface 34 of the pressing block 31 abuts against the strip 1 and continues to push the strip 1, so that the head of the strip 1 is pressed against the abutting surface 35 to form a hook 38. The abutting surface 35 is arranged on the lower clamping block 21. Both the pressing surface 34 and the abutting surface 35 are inclined slopes, so that the head of the strip 1 forms a hook 38 with an acute angle after being bent.​

[0027] The driving mechanism includes a mounting plate 30, a lifting cylinder 33 for driving the lifting of the mounting plate 30, and a rotating cylinder 32 for driving the rotation of the pressing block 31. The pressing block 31 is rotatably arranged on the mounting plate 30, and the rotating cylinder 32 is fixedly arranged on the mounting plate 30 to lift synchronously with the pressing block 31. The lifting cylinder 33 drives the mounting plate 30 to descend, so that the positions of the pressing surface 34 and the abutting surface 35 correspond front and back. The rotating cylinder 32 drives the pressing surface 34 to rotate towards the direction close to the abutting surface 35, so that the pressing surface 34 pushes the head of the strip 1 to press tightly against the abutting surface 35 for bending.

[0028] The feeding mechanism includes an upper roller 36 and a lower roller 37. The upper roller 36 and the lower roller 37 rotate in opposite directions. The strip 1 extends between the upper roller 36 and the lower roller 37. The upper roller 36 and the lower roller 37 clamp the strip 1 and convey it forward, so that the head of the strip 1 is inserted into the above-mentioned material passing gap and extends forward outside the clamping mechanism for the pressing mechanism to bend.

[0029] The pressing mechanism and the feeding mechanism are fixedly arranged on the frame 2. The clamping mechanism is slidably arranged on the frame 2 along the conveying direction of the strip 1. A translation mechanism is also arranged on the frame 2 to drive the clamping mechanism to translate. There is a bending station between the pressing mechanism and the feeding mechanism. The translation mechanism drives the clamping mechanism to move to this bending station. The feeding mechanism feeds the strip 1 into the material passing gap of the clamping mechanism. After the clamping mechanism clamps the strip 1, it is bent. After the bending is completed, the clamping mechanism clamps the strip 1 and moves forward to the next station. The clamping mechanism further includes a feeding frame 23. The upper clamping block 20 and the lower clamping block 21 are arranged on the feeding frame 23. The feeding frame 23 is slidably arranged on the frame 2 through a slide rail.

[0030] The working principle of the present utility model is as follows:

[0031] As Figure 2 shown, the cut strip 1 is fed between the upper roller 36 and the lower roller 37. After the upper roller 36 and the lower roller 37 rotate, they clamp the strip 1 and convey it forward, and insert the head of the strip 1 between the upper clamping block 20 and the lower clamping block 21. At this time, the airbag 22 is in a deflated state; after the head of the strip 1 extends outside the material passing gap, the upper roller 36 and the lower roller 37 stop rotating, and the airbag 22 is inflated to clamp the strip 1;

[0032] As Figure 3 shown, the lifting cylinder 33 drives the mounting plate 30 to descend, and the rotating cylinder 32 drives the pressing block 31 to rotate towards the direction close to the lower clamping block 21. The pressing surface 34 of the pressing block 31 abuts against the strip 1 and continues to push the strip 1, so that the head of the strip 1 is pressed tightly against the abutting surface 35 of the lower clamping block 21 to form a hook 38.

[0033] As Figure 4As shown, the airbag 22 deflates, and the upper roller 36 and the lower roller 37 rotate to drive the strip 1 to be conveyed forward, so that the bent strip 1 extends out of the clamping mechanism to form an extended section 39; the airbag 22 inflates to clamp the strip 1, the upper roller 36 and the lower roller 37 lose power and become passive wheels, and the translation mechanism drives the strip 1 to be translated forward as a whole to the next working station.
