Description

Technical Field

[0001] The invention relates to the technical field of stainless steel strip processing, in particular to a limiting device for stainless steel strips. Background Art

[0002] Stainless steel strip is a kind of steel plate with thin thickness, narrow width and long length produced by various steel rolling enterprises to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Its width is generally 20mm-200mm and it is supplied in coils. The stainless steel strip is cut by a steel strip slitting machine to obtain stainless steel strip of target length. Before cutting the stainless steel strip, the coiled stainless steel strip needs to be unwound. The stainless steel strip unwound by the unwinding machine has ups and downs and left-right deviation. When the steel strip slitting machine is used to cut the stainless steel strip, the stainless steel strip cutting accuracy is poor due to the uneven surface and left-right deviation of the stainless steel strip.

[0003] At present, the existing limit device structure for stainless steel strips is relatively complex. Generally, two sets of independent structures are used to limit the left and right sides and the top of the stainless steel. Each set of independent mechanisms requires a corresponding power device and transmission structure. The limit device has the defects of large overall mass, high cutting accuracy, low operating efficiency and no energy saving. Summary of the invention

[0016] 1. The limit device prevents the stainless steel strip from deviating left and right through the locking unit, and flattens the surface of the stainless steel strip through the flattening plate to ensure the cutting accuracy of the stainless steel strip.

[0017] 2. The limit device has the advantages of simple structure, efficient operation and energy saving. The locking unit and the flattening plate are connected to the pressing structure. By pressing the pressing structure, the surface of the stainless steel strip can be flattened and the left and right ends can be locked or released. No power device and corresponding transmission mechanism are required. No energy is consumed during use and no pollution is generated. The simple structure not only saves costs and reduces the overall quality of the limit device, but also has the advantages of low failure rate and easy maintenance.

[0018] 3. The limiting device, by setting a strip groove in the middle of the supporting plate, ensures that when the locking unit locks the side end of the stainless steel side plate, the supporting plate is in a vertical position, and the horizontal supporting plate is in horizontal contact with the stainless steel strip to cooperate with the flattening plate to flatten the surface of the stainless steel strip. Furthermore, the length of the flattening plate is slightly smaller than the width of the stainless steel strip, thereby ensuring the flatness of the surface of the stainless steel strip, and the stainless steel strip is protected by setting a silicone layer on the supporting plate and the horizontal supporting plate and a silicone plate on the flattening plate.
