SUMMARY OF THE INVENTION: An angular element comprises two half elements and three spacer liners with holes located on three adjacent faces of the angular element. Half elements and inserts are connected by welding. The corner element is made of manganese steel in which the ratio of;, manganese to carbon is 8-12, the total phosphorus and sulfur content is at most 0.04 wt.%, And the carbon content is at most 0.2 May. 17 ill.

Description

The invention relates to the corner elements of containers used to transport piece and bulk goods, liquids, etc.

The purpose of the invention is to improve manufacturability in the manufacture by cold deformation, preferably by flexible stamping.

This goal is achieved in that the corner element, containing two half-cells and three spacer liners with holes located and welded onto three adjacent its faces, also made with holes, is made of manganese steel, in which the ratio of manganese to carbon has a value of 8-12, the total content of phosphorus and sulfur is a maximum of 0.04 May. % and the carbon content is a maximum of 0.2 wt.%.

A steel sheet of this composition is homogeneous, bends well (Nmin a / 2, where a is the thickness of the material) and at -40 ° C has an impact strength of Kmin 21 J.

The steel sheets forming the base of the corner elements have a uniform crystalline structure also in the direction perpendicular to the rolling direction, and are suitable for cold pressing as technology, have an elongation (As) of more than 22% and excellent bending characteristics.

Tolerances on the weight and dimensions of corner elements made of steel sheet also meet the most stringent requirements (e.g., in ISO 1161). The individual phases of manufacture have a high degree of mechanization and can also be used in robotics, in addition, the production with high accuracy provides excellent repeatability.

The technology for the production of corner elements is based on simple and energy-efficient cold stamping and bending. Thus, the cut parts are subjected to cold bending and assembly. Welding together the individual elements is carried out using a welding robot with a simple geometric seam in a straight line in a horizontal, horizontal direction, the welding arc burns steadily, and repeats with large series

with high precision. At the end of welding, the corner elements do not require heat treatment.

In FIG. 1-3 depict, respectively, a top view, a side view and a section A-A in FIG. 1 of one embodiment of the corner element of the container; figure 4 - scan of one half element; figure 5 - scan of another half element; Figures 6 and 7 show one half element together with the spacer liners of this embodiment; Figures 8 and 9 show another half element of this embodiment; figure 10-12-spacer liners; on Fig and 14, respectively, semi-elements in a perspective view; on Fig, 15-17 - the corner element of the semi-elements with spacer liners, assembled in another embodiment.

The angular elements of the lower and upper surfaces of the container differ from each other only in the size of the holes located on their shorter edges, so the half elements 1 are made with two different holes. The half elements 2 are identical for the upper and lower corner elements and are designed so that they form a corner element with the half element 1.

Semi-element 1 with small modifications is a finished product: it can be used as a corner element in liquid cargo containers.

The dimensions and tolerances (Fig. 1-17) of the corner elements can be as follows:

length L 178 ± 1 mm

Width B 162 ± 1 mm

height H 118 ± 1 mm

weight M 9.60 - 9.75 kg ± 2% (depending on version).

The corner element according to the first embodiment consists of two half elements and three spacer inserts. A hole is made on each face of the half element 1. These holes are also made on a flat metal pattern, i.e. even before bending. There are no holes on the half element. On the verge of half element 1, liners are welded. 3-5. Corner elements are assembled from these two half elements 1 and 2.

According to the second variant, the corner element consists of a half element 1 made of a 10 mm sheet flexible with an internal radius of Rmin - a / 2 into a U-shaped profile, and also of a half element 2 of a sheet with a thickness of mm, from which a U-shaped profile with an inner radius is bent bending Nmin

a / 2. Corresponding holes are made on the semi-element 1, there are no holes on the semi-element 2. Spacer liners 3-5 are welded to the edges of the corner element.

By determining the size of the hole in the half element 1, it is decided for any of the options whether the corner element will go to the lower or upper part of the container. By changing direction

bending or by turning the sheet it is possible to perform a mirror., execution of a half element.

The listed parts are collected in the direction-finding tool and after inspection

sizes are welded. Then, one-sided continuous welding of fillet welds is performed.

As a final manufacturing phase, chamfering is performed on the outside of the holes (6x45 °).

The surface cleaning of the corner elements is carried out in their finished state.

The implementation of the semi-elements of manganese steel with a ratio of manganese to carbon from 8 to 12, the total content of phosphorus and sulfur up to 0.04 wt.%, And carbon 0.2 wt.% Provides high quality corner element of the container.
