Description

Anti-inclination unequal-thickness steel plate

Technical Field

The invention relates to the technical field of plates, transportation, processing and packaging, in particular to an anti-tilting unequal-thickness steel plate.

Background

When the unequal materials are piled together, because the thicknesses of the different materials are not completely equal, the piled materials have a tendency of sliding, if the friction force of the upper material and the lower material is smaller than the force of gravity in the inclined direction, the upper material can slide, especially when more unequal materials are piled and the overall height is higher, the height difference of the two ends of the materials is larger, the materials can slide easily when the friction force limit is reached, even if the materials can be piled statically and cannot slide, the materials can slide easily in the moving process. Especially, the steel plates with different thicknesses are heavy, the stacking height of the steel plates with different thicknesses is low so as not to slide or fall, the single lifting or transportation efficiency is low, and the risk of sliding still exists.

At present, in order to prevent that the material from inclining behind the sign indicating number material, often through increase the locating pin around the work or material rest and reduce the sign indicating number material height to realized the packing of material, however, it is comparatively troublesome when increasing the locating pin and making the dismantlement material, and, even increased the locating pin, because the problem of focus skew, the total height of material piling also can not be too high.

Disclosure of Invention

The invention aims to: aiming at the problems of dumping risk and low operation efficiency of the existing non-uniform thickness material stacking package, the anti-tilting non-uniform thickness steel plate is provided, and the difference of the stacking heights of the non-uniform thickness materials is not large through the formation of the convex part, so that the difference of the overall stacking height is not large, and the tilting is not easy to occur.

In order to achieve the purpose, the invention adopts the technical scheme that:

a non-uniform thickness steel plate capable of preventing inclination comprises a thick section and a thin section, wherein a part of the thin section protrudes to form a convex part. The non-uniform steel plate is a steel plate with a trapezoidal section, namely a steel plate with plane and non-parallel plate surfaces.

Preferably, the distance from the convex part to the surface, opposite to the convex part, on the steel plate is H, the thickness T of the end part of the thick section and the thickness M of the end part of the thin section are M, H is greater than T-M, the surface above the convex part is more close to the horizontal plane, the stacking height is better, and the stacking efficiency is better.

Preferably, H +/-0.05 mm = T [ cos (e) + 1-M, wherein e is the included angle between two plate surfaces of the steel plates with different thicknesses, so that the convex steel plates and the conventional steel plates are stacked at intervals and are more stable, the surfaces above the convex steel plates tend to be more horizontal, the stacking height is better, and the stacking efficiency is better.

Preferably, the convex part is formed by partially recessing the thin section, so that the processing and the manufacturing are convenient.

Preferably, the concave part formed by the depression is in a circular truncated cone shape or a partial circular truncated cone shape, so that the processing and the manufacturing are convenient, and the quality of the obtained steel plate is better. The recess is in the shape of a partial truncated cone, i.e. the recess is in the shape of a part of a truncated cone, for example half of a truncated cone.

Preferably, the convex part is formed by stamping the steel plate by stamping equipment and is sunken, so that the processing is convenient, the cost is low, and the efficiency is high.

Preferably, the projection is provided at an end of the thin section, and a portion of an end surface of the end corresponding to the projection is trapezoidal. The end parts of some steel plates are positioned in the waste material area, and the waste material area can be cut off after the steel plates are adopted to manufacture parts, so that the whole quality of the parts is good. In addition, if the convex part is located in the middle area of the steel plate, when parts are machined by the steel plate, the surface area of the steel plate is increased due to the existence of the convex part, cracks can appear in the convex part area when the parts are stamped, the parts are scrapped, the convex part is placed at the end part, the concave part when the convex part is formed by sinking can be in a partial circular truncated cone shape, when the parts are stamped by the steel plate, redundant materials of the convex part can flow and extend towards the steel plate conveniently, cracks can not appear on the parts after stamping, and the quality of the parts is.

Preferably, the two convex parts are symmetrically arranged relative to the steel plate, and the convex steel plate and the conventional steel plate are stacked at intervals and then are less prone to toppling or sliding.

In summary, due to the adoption of the technical scheme, compared with the prior art, the application has the beneficial effects that: when using, the unequal-thickness steel plates of this application and the conventional unequal-thickness steel plates that do not have the convex part are overlapped at intervals, wholly stack and more be difficult to empty or the landing, can effectively prevent the slope or the landing of unequal-thickness material when the stack, improved the pile up neatly height of allowwing simultaneously to improved the packing efficiency and the operating efficiency of unequal-thickness material, and, also reduced the material loading time in the punching press, prevented to tear open the slope, the landing of material when cutting machine lifts the sheet material, improved production efficiency, avoided the potential safety hazard.
