Abstract
The invention discloses a squeezing barrel structure, which comprises a squeezing barrel inner barrel, a squeezing barrel middle barrel and a squeezing barrel outer barrel which are sequentially distributed from inside to outside, wherein an inner hole on one side of the squeezing barrel inner barrel is of a cylindrical structure, and an inner hole on the other side of the squeezing barrel inner barrel is of a conical structure.
Description
Technical Field
The invention belongs to the field of metallurgical equipment, and relates to an extrusion container structure.
Background
In the aluminum alloy extrusion production, the extrusion container is used as a part of an extrusion tool, the stress condition and the load condition of the extrusion container are relatively severe, the extrusion container belongs to a wearing part, and the extrusion container needs to be irregularly replaced according to the wearing condition of the inner wall of the extrusion container. The traditional extrusion container generally adopts three layers or two layers of prestressed containers, and the inner hole is a full circle and penetrates through the whole length of the extrusion container. However, in the actual production process, the aluminum ingots extruded are different in length and are extruded from the extrusion die, so that the side, close to the die, of the inner wall of the extrusion cylinder is seriously abraded, and the side, far away from the die, of the inner wall of the extrusion cylinder is slightly abraded. In addition, in the extrusion process, the time of the surface friction of the aluminum ingot on the inner wall of the extrusion container close to the die is longer, the time of the surface friction of the aluminum ingot on the side far away from the die is shorter, and meanwhile, the temperature of the inner wall of the extrusion container close to the die is higher than that of the inner wall of the extrusion container far away from the die, so that the abrasion degree of the inner wall of the extrusion container is increased. Therefore, after the extrusion cylinder is used for a long time, the inner hole is generally in a horn mouth shape, the inner hole close to the side of the die is seriously abraded, the size is obviously enlarged, the inner hole far away from the die is slightly abraded, and the size is slightly changed. The wear of the inner bore close to the die side leads on the one hand to the phenomenon of "aluminum return" during extrusion and, in addition, the extrusion cylinder has to be replaced if the wear is severe.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a structure of an extrusion container, which can relieve the aluminum return phenomenon and has long service life.
In order to achieve the purpose, the extrusion container structure comprises an extrusion container inner container, an extrusion container middle container and an extrusion container outer container which are sequentially distributed from inside to outside, wherein an inner hole on one side of the extrusion container inner container is of a cylindrical structure, and an inner hole on the other side of the extrusion container inner container is of a conical structure.
And assembling the inner extrusion container barrel, the middle extrusion container barrel and the outer extrusion container barrel according to preset interference.
The inner hole of the inner cylinder of the extrusion container takes the middle point in the length direction as a boundary, the inner hole at one side of the inner cylinder of the extrusion container is of a cylindrical structure, and the inner hole at the other side of the inner cylinder of the extrusion container is of a conical structure.
The inner wall of the conical structure forms an included angle of 0.05 degrees with the central line of the extrusion container along the length direction.
The diameter of the cylindrical structure is 270 mm.
The inner hole of one side of the inner barrel of the extrusion container is of a cylindrical structure, the inner hole of the other side of the inner barrel of the extrusion container is of a conical structure, and abrasion of the inner wall of the inner barrel 1 of the extrusion container in the extrusion process is supplemented and offset through the conical structure.
The invention has the following beneficial effects:
when the extrusion container structure is operated specifically, the inner hole on one side of the inner container of the extrusion container is of a cylindrical structure, and the inner hole on the other side of the inner container of the extrusion container is of a conical structure, so that the abrasion of the inner wall of the inner container of the extrusion container in the extrusion process is supplemented and counteracted through the conical structure, the service life of the extrusion container is prolonged, the aluminum return phenomenon is relieved, and the uneven degree of the abrasion of the extrusion container is reduced.
Furthermore, the inner wall of the conical structure forms an included angle of 0.05 degrees with the central line of the extrusion container along the length direction, so that the phenomenon of scraping the container due to the contact between the outer circle surface of the extrusion rod and the inner wall of the extrusion container can be avoided.

Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments, and are not intended to limit the scope of the present disclosure. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
There is shown in the drawings a schematic block diagram of a disclosed embodiment in accordance with the invention. The figures are not drawn to scale, wherein certain details are exaggerated and possibly omitted for clarity of presentation. The shapes of various regions, layers and their relative sizes and positional relationships shown in the drawings are merely exemplary, and deviations may occur in practice due to manufacturing tolerances or technical limitations, and a person skilled in the art may additionally design regions/layers having different shapes, sizes, relative positions, according to actual needs.
Referring to fig. 1 and 2, the extrusion container structure of the present invention includes an inner container 1, a middle container 2 and an outer container 3, which are sequentially distributed from inside to outside, and the inner container 1, the middle container 2 and the outer container 3 are assembled according to a predetermined interference to ensure that the inner container 1 has sufficient prestress.
The inner hole of the inner tube 1 of the extrusion container is defined by the middle point in the length direction, the inner hole on one side of the inner tube 1 of the extrusion container is of a cylindrical structure, the inner hole on the other side of the inner tube 1 of the extrusion container is of a conical structure, and the inner wall of the conical structure forms an included angle of 0.05 degrees with the central line of the extrusion container along the length direction.
The conical design of the invention can supplement or offset the abrasion of the inner wall of the inner cylinder 1 of the extrusion container in the extrusion process. Meanwhile, the conical degree of only 0.05 degrees does not cause the contact between the outer circle surface of the extrusion rod and the inner wall of the inner cylinder 1 of the extrusion cylinder, so that the phenomenon of cylinder scraping is avoided.
