Description

Technical Field

[0001] The utility model belongs to the technical field related to cold rolling mills, and particularly relates to a novel working roll bending device for a cold rolling mill. Background Art

[0002] The bending device of the working roll of the cold rolling mill is used to adjust the gap between the working rolls of the cold rolling mill to ensure that the plates can be processed correctly during the cold rolling process. It mainly consists of two parts: the upper bending roll and the lower bending roll. By adjusting the position and strength of the upper bending roll and the lower bending roll, the gap between the working rolls of the cold rolling mill can be effectively controlled to achieve accurate processing of the plates. However, when the bending rolls extrude and shape the plates and output them outward, a downward force will be generated due to the weight of the plates, which will cause the shaped plates to deviate from the upper side of the plate when falling. The plate deviation will cause the gap between the working rolls of the cold rolling mill to be uneven, resulting in uneven thickness of the plates during processing, affecting the quality and processing accuracy of the plates. It will also cause abnormal contact between the working rolls and the plates, causing wear on the working roll surface or damage to the plate surface, affecting the processing effect. Utility Model Content

[0003] The purpose of the present utility model is to provide a new type of cold rolling mill working roll bending device to solve the problem proposed in the above background technology that the plate offset will lead to uneven gaps between the cold rolling mill working rolls, resulting in uneven thickness of the plates during processing, affecting the quality and processing accuracy of the plates, and also leading to abnormal contact between the working rolls and the plates, causing wear on the working roll surface or damage to the plate surface, affecting the processing effect.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1-3 A novel cold rolling mill work roll bending device shown includes a fixed frame 4 and a bending roll 2;

[0021] The fixing frame 4 is installed on the left side of the upper end of the base frame 9. Two bending rollers 2 are placed one above the other between the left and right ends of the inner wall of the fixing frame 4. The two bending rollers 2 are used to squeeze the plate to shape it. Two guide blocks 12 are provided on the front side of the fixing frame 4.

[0022] Fixed rods 1 are provided on both sides of the front end of the fixing frame 4. Cross bars 13 are provided on the front sides of the two fixed rods 1. The two cross bars 13 are connected and fixed to the guide blocks 12. Fixed grooves 17 are provided on the opposite sides of the two guide blocks 12 for clamping the plate.

[0023] The plate is squeezed and shaped by the two bending rollers 2. When the squeezed plate moves forward, the left and right edges of the plate pass through the fixed grooves 17 of the guide block 12. When the plate is conveyed forward, it is supported by the guide block 12 to prevent the plate from bending too much and causing creases, and to prevent the upper plate from being deflected.

[0024] like Figure 2 and Figure 3 As shown, the front ends of the two fixed rods 1 are each provided with a sleeve 11, and the two cross bars 13 are inserted into the sleeve 11 for fixation. The two cross bars 13 can slide left and right on the inner wall of the sleeve 11 to adjust the spacing between the two guide blocks 12. The front ends of the two sleeves 11 are both provided with knobs 10 extending inward. The two knobs 10 are used to screw and extrude the cross bars 13 inserted into the interior of the fixed sleeve 11. The cross bars 13, the fixed rods 1 and the guide blocks 12 are all made of stainless steel, and the cross bars 13 and the guide blocks 12 are fixedly connected by welding.

[0025] The guide blocks 12 can adjust the spacing according to the different widths of the plates. The spacing between the two guide blocks 12 can be adjusted by unscrewing the knob 10 from the sleeve 11 and sliding the cross bar 13 left and right in the sleeve 11. After the spacing is adjusted, the knob 10 is screwed into the sleeve 11 to squeeze the cross bar 13 to fix it.

[0026] like Figure 1 As shown, tying rollers 3 are provided on the upper and lower sides of the inner wall bending roller 2 of the fixed frame 4, and multiple bearing seats 14 are provided on the upper and lower sides of the left and right ends of the fixed frame 4. The bearing seats 14 are used to fix the tying rollers 3. A motor 8 is provided on the right side of the upper end of the base frame 9, and a power transmission box 6 is provided on the left side of the motor 8. The motor 8 and the power transmission box 6 are connected by a connecting roller 7, and the power transmission box 6 and the two bending rollers 2 are connected by two transmission shafts 5.

[0027] The motor 8 drives the connecting roller 7 to transmit power to the power transmission box 6, and the power transmission box 6 transmits the power brought by the motor 8 to the two transmission shafts 5 to drive the bending roller 2 to rotate and extrude the plate.

[0028] like Figure 1 As shown, fixing plates 15 are provided on the lower sides of the front and rear ends of the chassis 9 , and multiple bolts 16 are provided on the upper ends of the fixing plates 15 . The chassis 9 is fixed to the ground by the multiple bolts 16 on the upper ends of the fixing plates 15 .

[0029] The steel chassis 9 is fixed to the floor of the workshop by a plurality of bolts 16 on the upper end of the fixing plate 15 .

[0030] The working principle of the present invention is as follows: before the plate is shaped and conveyed outside between the two bending rollers 2, the guide block is first slid left and right between the sleeves 11 to adjust the distance between the two guide blocks, so that the distance between the two guide blocks corresponds to the width of the plate, and the motor 8 drives the connecting roller 7 to transmit power to the power transmission box 6. The power transmission box 6 transmits the power brought by the motor 8 to the two transmission shafts 5 to drive the bending rollers 2 to rotate and squeeze the plate. When the plate is shaped by the bending rollers 2 and conveyed forward, the left and right edges of the plate pass through the fixed grooves 17 between the guide blocks and are conveyed forward. By clamping the edge of the plate in the guide block fixed groove 17 for fixed conveying, it can be prevented that the position of the upper plate is shifted when the plate falls, resulting in uneven thickness of the processed plate.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
