Main machine structure of super-heavy double-action extruding machine

Abstract

The invention belongs to the field of metallurgical equipment and particularly relates to a new structure of super-heavy extruding equipment. The new structure comprises a rear beam, pull rod pressing sleeves and a front beam which are used for forming an extruding machine prestressed rack, wherein an external perforation system is connected with the rear end of the rear beam and comprises a perforation rear beam provided with a fixed perforation cylinder and perforation pull rod pressing sleeves; two ends of each perforation pull rod pressing sleeve are connected with the extruding machine rear beam and the perforation rear beam respectively; a large main working cylinder is fixed on the extruding machine rear beam, small main working cylinders are symmetrically arranged on the left side and the right side of the large main working cylinder, and four side cylinders are symmetrically arranged on the upper side and the lower side of the large main working cylinder; a main plunger of the large main working cylinder is connected with a moving cross beam; an extruding tool is mounted on the moving cross beam; a pair of main scissors is fixed on the extruding machine front beam; and an extruding barrel is arranged between the extruding machine front beam and the moving cross beam. The main machine structure manner is designed for the structure of an extruding machine with the largest tonnage in the industry, the overall performance of the super-heavy extruding machine can be improved, and the strength and extruding precision of super-heavy backward extruding equipment can be improved.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, and in particular relates to a main structure of a super-heavy double-action extrusion machine. Background technique [0002] At present, the largest double-action aluminum extrusion machine that has been put into production in China is the imported 150MN extrusion machine, and the domestically produced 125MN double-action aluminum extrusion machine. With the advancement of machining technology and the expansion of the application range of aluminum and aluminum alloys, more super-heavy double-action extrusion equipment (such as 360MN) is required to be put into use. [0003] The ultra-heavy extruder involves extreme manufacturing, and it is necessary to consider various aspects such as extreme processing, road transportation, lifting and installation, and propose a reasonable structural form after comprehensive consideration. [0004] On the other hand, the structure currently used in extr...

Problems solved by technology

[0004] On the other hand, the structure currently used in extrusion machines is suitable for small-tonnage extrusion machines. If this structure is applied to super-heavy extrusion machines, there will be problems of unstable needle positioning and poor precision; Multiple components lead to poor rigidity of the back beam; the use of a rod-operated scissor cylinder increases the height of the main machine of the extrusion machine, making the structure of the whole machine occupy a large space and is uncoordinated
