Embodiment Construction
[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031]The structure of the embodiment of the stainless steel F-type water stop sheet of the present invention is as follows figure 1 As shown, the stainless steel F-type waterproof sheet of this embodiment includes a bottom edge 1 arranged horizontally, the middle part of the bottom edge 1 has a contraction groove 5 with an inverted U-shaped structure, and the right side of the bottom edge 1 has a 45° angle with the bottom The right protective edge 2, the left side of the bottom edge 1 has a left protective edge 3 at an angle of 90° with the bottom edge, the end of the left protective edge 3 is provided with a corner straight edge 4, and the corner straight edge 4 has a 90° There are three ribs 6 in an arc-shaped convex structure on the water-stop sheet, two of which are arranged on the bottom edge 1 and are respectively located on both sides...

The invention discloses a stainless steel F-type water stop strip and a manufacturing method thereof. The manufacturing method of the stainless steel F-type water stop strip includes the steps of longitudinally shearing strip steel, performing uncoiling and flattening, pasting a protective film, performing cold roll forming and performing cold roll reshaping. For the step of cold roll forming, the strip steel pasted with the protective film deforms through continuous roll bending way by way via rollers, and deformation rollers with the paired upper roller and lower roller are matched with a guide stand roller, lateral stand rollers and a straightening mechanism; firstly, three reinforcing ribs and a middle shrinking groove of the water stop strip are formed; then, a straight edge part of a left side edge corner of the water stop strip is formed, and next a left protective edge and a right protective edge of the water stop strip are formed. The step of cold roll reshaping refers to performing finishing on a product obtained through the step of cold roll forming. According to the manufacturing method, each bending corner of the F-type water stop strip is independently formed, so the size of each part is more accurate, and the F-type water stop strip is more convenient to adjust in practical use. The manufacturing method well overcomes the various defects caused by bending and welding technologies in the prior art on the aspects of process design, device selection and the like.
Description
technical field [0001] The invention relates to a water stop sheet and a manufacturing method thereof, in particular to a stainless steel F-shaped water stop sheet and a manufacturing method thereof, belonging to the technical field of water stop sheet production. Background technique [0002] Water-stop sheets are widely used in many fields such as dam seepage-proof and water-proof structures. Traditional water-stop sheets are made of copper materials, but the following problems and defects have been exposed during the use of copper water-stop sheets: First, the strength Low, easy to tear at the end; second, the material is soft and easy to deform, and construction is inconvenient; third, copper is expensive and the cost is too high. Therefore, the stainless steel water-stop sheet came into being and gradually replaced the traditional copper water-stop sheet. The mechanical properties and strength of stainless steel are higher than that of copper, and the material price is...
