Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled steel plate processing equipment, in particular to a cold-rolled steel plate straightening mechanism for processing. Background Art

[0002] Cold rolled steel plate is a common product produced by steel mills. In the steel plate production line, cold rolled steel plate straightening machines are usually used to straighten the produced steel plates to make their surface smoother and their size more accurate. A large number of cold rolled steel plates are needed in the automobile manufacturing process. Cold rolled steel plate straightening machines can be used to process these steel plates to ensure that they meet the high requirements of automobile production, such as flatness, surface quality, etc.

[0003] After searching: Chinese patent announcement number: CN217775180U, it involves the field of coking production equipment, and discloses a cold-rolled steel plate straightening mechanism for processing, including a placement plate, the front side of the upper surface and the rear side of the upper surface of the placement plate are fixedly connected with a convex slide groove, the convex slide groove is slidably connected with a convex slider, and the upper surface of the convex slider is fixedly connected with a support plate. The cold-rolled steel plate straightening mechanism for processing is provided with a first slide rail, a second slide rail, a universal wheel and a round hole, and the placement plate is moved downward by an electric push rod so that the first drive column and the second drive column drive the first support leg and the second support leg to retract inward, and the universal wheel under the T-shaped support plate extends from the round hole, so that the device can be folded and easily moved when moving, and by tying a rope on the sleeve ring, the personnel can pull the device without bending over, thereby solving the problem that the cold-rolled steel plate straightening mechanism currently on the market is difficult to carry or move.

[0004] The above-mentioned patent embodiment records that "the steel plate to be straightened is placed on the left side of the placement plate 1, and the rotating disk 11 is rotated to make the clamp 9 move downward along the guide column 8 to clamp the steel plate, and the handle 6 is held and pushed to the left to make the convex slider 3 move to the left along the convex slide groove 2, so that the straightening roller 5 moves to the left and starts to straighten the steel plate." The above-mentioned embodiment records that the steel plate is clamped and fixed by manually rotating the rotating disk to move the clamp along the guide column, so that only steel plates of fixed size can be clamped and fixed, which will result in the steel plate being unable to be clamped and fixed when it is too long or too wide. Therefore, in view of the above-mentioned deficiencies, a new type of cold-rolled steel plate straightening mechanism for processing is proposed. Utility Model Content
