Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing and relates to an online strip burr finishing machine. Background Art

[0002] When slitting steel coils, due to factors such as cutting tools and equipment, process parameter settings, material properties, and other factors, the strip material after slitting may have burrs. These burrs affect the processing performance and efficiency of the strip material and pose multiple risks. Therefore, it is necessary to deal with the burrs on the strip material. Existing deburring devices mostly include a lower roller and several upper pressure rollers arranged above the lower roller. The upper pressure rollers and lower rollers roll the strip material to deburr it. However, most existing upper pressure rollers are fixed and cannot be adjusted to meet the deburring requirements of multiple strips of different specifications, resulting in poor adaptability.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The roller arrangement unit enables the deburring unit to be automatically arranged transversely on the first transverse guide rail assembly according to the specifications and number of strips, ensuring that the pressure roller of each deburring unit corresponds to the position of the strip one-to-one, and can meet the deburring requirements of strips of different specifications. It has strong adaptability and high transverse movement accuracy of the deburring unit. When the pressure roller presses down to deburr, the self-locking positioning structure can lock the deburring unit laterally to ensure that the position of the deburring unit will not move, thereby ensuring the deburring quality of the pressure roller.

[0007] In the above-mentioned online strip deburring machine, the first transverse guide rail assembly includes a first transverse guide rail, the center axis of the first transverse guide rail is parallel to the center axis of the lower roller, and the deburring unit is connected to the first transverse guide rail through a slider.

[0008] When the deburring unit moves laterally on the first transverse guide rail, the moving axis is always parallel to the center axis of the lower roller. The high transverse movement accuracy can ensure the deburring quality of the pressing roller.

[0009] In the above-mentioned online strip burr finishing machine, the row roller unit includes a row roller seat, the row roller seat is connected to the frame through the second transverse guide rail assembly, and a transverse driving mechanism is provided between the row roller seat and the frame, which can drive the row roller seat to move along the second transverse guide rail assembly. The row roller seat is provided with a shifting claw, and a telescopic drive is provided between the shifting claw and the row roller seat, which can radially extend and retract along the second transverse guide rail assembly.

[0010] The operation of the transverse drive mechanism can drive the row roller seat to move along the second transverse guide rail assembly so that the moving claw of the row roller seat is aligned with the deburring unit. Then the telescopic drive operates to drive the moving claw to extend radially and cooperate with the deburring unit for fixation. Finally, the operation of the transverse drive mechanism drives the row roller seat to move along the second transverse guide rail assembly and synchronously drives the deburring unit to move transversely for arrangement, ensuring that the pressure roller of each deburring unit corresponds to the position of the strip. After the arrangement is completed, the telescopic drive resets.

[0011] In the above-mentioned online strip burr finishing machine, the second transverse guide rail assembly includes a second transverse guide rail, the center axis of the second transverse guide rail is parallel to the center axis of the lower roller, and the row of rollers is connected to the second transverse guide rail through a slider.

[0012] When the row of roller seats moves laterally on the second transverse guide rail, the moving axis is always parallel to the center axis of the lower roller, and the transverse movement accuracy is high.

[0016] After the toggle claw is aligned with the burr pressing unit, it extends out and is matched and fixed with the toggle block of the burr pressing unit.

[0017] In the above-mentioned online strip deburring finishing machine, the deburring unit includes a guide rod cylinder, the pressure roller is provided on the push plate of the guide rod cylinder, a transverse positioning plate is provided above the guide rod cylinder, and a guide transverse groove distributed axially along the first transverse guide rail assembly is provided on the transverse positioning plate. The guide rod cylinder is connected to the guide transverse groove through a guide member, and the guide member is the guide rod of the guide rod cylinder. An anti-drop ring is provided at the upper end of the guide rod, and a self-locking positioning structure is provided between the anti-drop ring and the transverse positioning plate, which can laterally lock the guide rod cylinder when the pressure roller of the guide rod cylinder presses down to remove burrs.

[0018] The push plate of the guide rod cylinder is pushed out to drive the pressure roller to press down to remove burrs. The guide rod of the guide rod cylinder moves downward accordingly. The self-locking positioning structure between the anti-drop ring at the upper end of the guide rod and the horizontal positioning plate can lock the guide rod cylinder laterally to ensure that the position of the guide rod cylinder will not move, thereby ensuring the deburring quality of the pressure roller.

A self-locking positioning structure 7 that can lock the burr pressing unit 3 when the pressure roller 6 of the burr pressing unit 3 presses down to remove burrs is provided between the burr pressing unit 3 and the frame 1.

[0033] In the present invention, after the specifications and number of strips after slitting are determined, the row of roller units 5 sequentially move the deburring units 3 laterally on the first transverse guide rail assembly 4, so that the pressing rollers 6 of each deburring unit 3 correspond to the position of the strip one by one. When the strip passes through the lower roller 2 and the pressing roller 6, the pressing roller 6 of the deburring unit 3 presses down to remove the burrs on the strip, and the self-locking positioning structure 7 can lock the deburring unit 3 laterally to ensure that the position of the deburring unit 3 will not move.

[0035] When the deburring unit 3 moves laterally on the first transverse guide rail, the moving axis is always parallel to the central axis of the lower roller 2, and the transverse movement accuracy is high. When the pressing roller 6 presses down to remove burrs, the self-locking positioning structure 7 can laterally lock the deburring unit 3 to ensure that the position of the deburring unit 3 will not move, thereby ensuring the deburring quality of the pressing roller 6.

[0036] Specifically, combined Figure 1 As shown, the first transverse guide rail assembly 4 includes a first transverse guide rail 8 , the central axis of the first transverse guide rail 8 is parallel to the central axis of the lower roller 2 , and the deburring unit 3 is connected to the first transverse guide rail 8 via a slider.

[0037] The deburring unit 3 is slidably connected to the first transverse guide rail 8 through a slider. When the deburring unit 3 moves laterally on the first transverse guide rail 8, the moving axis is always parallel to the center axis of the lower roller 2.

[0039] The operation of the transverse drive mechanism 11 can drive the row roller seat 9 to move along the second transverse guide rail assembly 10 so that the driving claw 12 of the row roller seat 9 is aligned with the deburring unit 3, and then the telescopic drive 13 operates to drive the driving claw 12 to extend radially and cooperate with the driving block 17 of the deburring unit 3 to be fixed. Finally, the operation of the transverse drive mechanism 11 drives the row roller seat 9 to move along the second transverse guide rail assembly 10 and synchronously drives the deburring unit 3 to move transversely for arrangement, ensuring that the pressure roller 6 of each deburring unit 3 corresponds to the position of the strip. After the arrangement is completed, the telescopic drive 13 is reset.

[0040] Specifically, combined Figure 2 As shown, the second transverse guide rail assembly 10 includes a second transverse guide rail 14 , the central axis of the second transverse guide rail 14 is parallel to the central axis of the lower roller 2 , and the row roller seat 9 is connected to the second transverse guide rail 14 via a slider.

[0041] The row roller seat 9 is slidably connected to the second transverse guide rail 14 through a slider. When the row roller seat 9 moves laterally on the second transverse guide rail 14, the moving axis is always parallel to the center axis of the lower roller 2, and the transverse movement accuracy is high.

[0042] Specifically, combined Figure 2 As shown, the transverse driving mechanism 11 includes a transverse screw rod 15 arranged parallel to the second transverse guide rail 14 , one end of the transverse screw rod 15 is connected to a screw driver 16 , and a screw nut of the transverse screw rod 15 is connected to the row roller seat 9 .

[0043] The operation of the screw driver 16 can drive the transverse screw 15 to rotate and make the row roller seat 9 move laterally on the second transverse guide rail 14 through the screw nut of the transverse screw 15 .

[0044] Specifically, combined Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the deburring unit 3 includes a guide rod cylinder 18, the pressing roller 6 is provided on the push plate 19 of the guide rod cylinder 18, a transverse positioning plate 20 is provided above the guide rod cylinder 18, and a guide transverse groove 21 distributed axially along the first transverse guide rail assembly 4 is provided on the transverse positioning plate 20.

[0045] The push plate 19 of the guide rod cylinder 18 is pushed out to drive the pressure roller 6 to press down to remove burrs. The guide rod 23 of the guide rod cylinder 18 is inserted into the guide transverse groove 21. When the push plate 19 is pushed out, the guide rod 23 moves downward. The self-locking positioning structure 7 between the anti-drop ring 24 at the upper end of the guide rod 23 and the transverse positioning plate 20 can lock the guide rod cylinder 18 laterally to ensure that the position of the guide rod cylinder 18 will not move, thereby ensuring the deburring quality of the pressure roller 6.

[0046] Specifically, combined Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the self-locking positioning structure 7 includes a locking spring 25 arranged on the guide rod 23, the upper end of the locking spring 25 rests on the anti-drop ring 24, and the lower end rests on the transverse positioning plate 20. A supporting plate 26 is provided between the transverse positioning plate 20 and the locking spring 25.

[0047] When the push plate 19 pushes out the guide rod 23 and moves downward, the anti-drop ring 24 presses the locking spring 25 on the guide rod 23.

[0050] The lower roller 2 is a tapered roller to prevent the roller surface from crushing the material and leaving marks. The surface of the lower roller 2 and the pressure roller 6 is nitrided and hardened to improve the deburring effect and extend the service life.

[0051] The working principle of the present utility model is as follows: after the specifications and number of strips after slitting are determined, the screw driver 16 drives the row roller seat 9 to move laterally on the second transverse guide rail 14 so that the toggle claw 12 of the row roller seat 9 corresponds to the toggle block 17 of the guide rod cylinder 18, and then the telescopic driver 13 drives the toggle claw 12 to extend radially and cooperate with the toggle block 17 to be fixed, and the screw driver 16 continues to operate and synchronously drives the guide rod cylinder 18 to move laterally on the first transverse guide rail 8 so that the pressure roller 6 of the guide rod cylinder 18 corresponds to the position of the strip, until all the guide rod cylinders 18 are arranged to ensure that the pressure roller 6 of each guide rod cylinder 18 corresponds to the position of the strip.

[0052] When the strip passes through the lower roller 2 and the pressure roller 6, the push plate 19 of the guide rod cylinder 18 is pushed out to drive the pressure roller 6 to press down to remove burrs, and the guide rod 23 of the guide rod cylinder 18 follows and moves downward. The anti-drop ring 24 presses the locking spring 25 and applies continuous pressing force to the transverse positioning plate 20 through the push plate 26 to ensure that the push plate 26 is tightly fixed to the transverse positioning plate 20 to achieve locking, thereby preventing the pressure roller 6 from shifting.
