Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the present invention Examples, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] like Figure 1 to Figure 5 As shown, the structural relationship is as follows: the extrusion channel is vertically arranged in the extrusion cylinder 2, the extrusion rod 1 and the vertical plug 8 are respectively sealed and fitted to the top and bottom ends of the extrusion channel, and the extrusion between the two The channel is filled with high-pressure medium 13; th...

Abstract

The invention discloses a horizontal and automatic blank guiding mechanism for a corner type hydrostatic extrusion device and relates to the technical field of guiding mechanisms. An extruding rod anda vertical plug are in seal fit with the inner top end and the inner bottom end of an extruding passage separately; the extruding passage between the extruding rod and the vertical plug is filled with a high-pressure medium; a feeding passage is transversely arranged and is intersected with and communicates with the extruding passage between the extruding rod and the vertical plug; a concave dieand a horizontal plug are in seal fit with the inner two ends of the feeding passage separately; a guiding ring is in seal fit with the interior of the feeding passage and is connected with the horizontal plug through a horizontally arranged guiding spring; and the two ends of a blank are matched with the interior of the concave die in a clamping connection manner and are mounted on the guiding ring separately. According to the horizontal and automatic blank guiding mechanism, the guiding spring is arranged, is always in the compressed state during the extruding process, and gradually recoversto the natural length along with operation of the extruding process, so that horizontal guiding and positioning of the blank are automatically realized, and the quality of an extruded piece is improved; and a blank support for placing the blank is arranged at the bottom of the guiding ring to place the blank more steadily.

Description

technical field [0001] The invention relates to the technical field of guiding mechanisms, in particular to a billet horizontal guiding mechanism for a corner hydrostatic extrusion device. Background technique [0002] The metal plastic forming processing industry is an important part of the machinery manufacturing industry, and plays an extremely important role in aerospace, automobiles, weapons, engineering machinery, light industry, and household appliances. The production of modern industrial products is often supported by plastic processing technology. [0003] As a new processing method with less or no cutting, the hydrostatic extrusion process is also called punchless extrusion or hydraulic extrusion. A processing method in which the blank is formed by forming the metal through a die. Hydrostatic extrusion uses high-pressure media to transmit pressure and utilizes the unique isotropic properties of the fluid, that is, during the extrusion process, the billet is subj...
