Problems solved by technology

However, in the etching process, chemicals are often used. The used solution is strongly acidic and contains a variety of heavy metals. Direct discharge will cause great pollution to the environment, and its sewage treatment consumes resources and energy.
Moreover, it is difficult to ensure the depth of patterns such as concave holes in the steel sheet after etching

Embodiment 1

[0024] The present invention provides a method for processing concave-hole steel sheet, which includes the following steps:

[0025] Step one, split the plane pattern of the designed steel sheet: split the designed steel sheet with a thickness of t and a hole depth of t / 2 for the split design.

[0026] There are many options for splitting, that is, two steel sheets with the same thickness of t / 2 and the same outer contour are used, and holes and other patterns are designed on their surfaces. The size, shape, and position of the holes and patterns can be symmetrical or asymmetrical. , The range of t can be 0.3mm-10mm. (Symmetry is the positioning hole, the hole of the main part and its pattern are asymmetric)

[0027] Or split the steel sheet with thickness t into two steel sheets with thickness t / n and thickness (t-t / n) with the same outer contour, n≥2, but with different holes and other patterns on the surface.

[0028] Alternatively, the steel sheet with a thickness of t can be spl...

Embodiment 2

[0041] The present invention provides a method for processing concave-hole steel sheets. The steps are basically the same as those in the first embodiment. The difference is that step four can be replaced by: directly cutting multiple steel sheets according to the design and according to the shape of the steel sheet Stack them one by one, use a rubber hammer (other equipment for squeezing and hammering can also be used), and perform laser welding after compaction. The processing method does not need butt welding, is more concise, and is suitable for processing small-volume concave-hole steel sheets.

Abstract

The invention discloses a machining method for a steel sheet with concave holes, and belongs to the technical field of the tyre mold. The machining method comprises the following steps that (1) plane patterns of a designed steel sheet are divided, when design is completed, the designed steel sheet with the thickness of t and concave hole depth of t / 2 is divided into at least two sheets; (2) the steel sheets are cut, according to the designed patterns, the steel sheets with the concave holes are cut respectively, and the holes and other patterns on the steel sheets are cut into through-hole forms; (3) deburring is conducted; (4) the multiple steel sheets sequentially stacked up are connected in a butt joint mode through spot welding; and (5) welding forming is conducted, peripheral outer sides of the steel sheets connected in the butt joint mode are welded together. According to the machining method for the steel sheet with the concave holes, various chemical reagents in the etching technology are avoided to be used, so that various waste water and other by-products are not generated, and the machining technology is clean and environmentally friendly. In addition, the shapes and depth of the holes and patterns on the steel sheets can be controlled accurately, and the machining method is widely applied to the manufacture of tyre molds.

Description

Technical field [0001] The invention relates to the technical field of tire molds, in particular to a method for processing concave-hole steel sheets. Background technique [0002] The tire tread includes many grooves of different widths extending along the tire axial direction and one side thereof. This kind of groove will have a great impact on the performance of the tire, especially in the braking performance of the tire and its grip on wet roads. The narrower grooves on the tire tread are realized by steel sheets arranged on the blocks of the tire mold and the tire. The shape, size and other characteristics of the steel sheet can have a significant impact on the tire grip performance and drainage performance. [0003] Because the steel sheet used is very thin, and its surface often has holes of different depths or other patterns, it is very difficult to implement ordinary machining methods. Existing steel sheet processing methods mostly use a process of stamping on a die aft...
