Problems solved by technology

The extrusion rod, the extrusion shaft pad and the extrusion rod gland each have a mating surface. Due to the large reference size of the 9000T extrusion rod, it is difficult to ensure that both mating surfaces are in place after processing. When a certain surface is positioned accurately There may be a gap on the other side, so that the centering of the extrusion rod will not be reliable

Abstract

The invention provides an extrusion rod compressing apparatus for an extruder. The apparatus comprises an extrusion rod, an extrusion rod gland, an extrusion rod shaft pad and an elastic bolt structure, the extrusion rod gland is sleeved on the extrusion rod, and the tail end of the extrusion rod is fixed in the extrusion rod shaft pad; and the extrusion rod gland is fixed to the extrusion rod shaft pad through the elastic bolt structure. The extrusion rod compressing apparatus for the extruder guarantees proper compression of the fitting surfaces of the extrusion rod and the extrusion rod gland, and allows a certain gap to be residual between the close surfaces of the extrusion rod and the extrusion shaft pad, and a compressing device containing a disk spring group structure is adopted to compress the gap. The disk spring is elastic, so a certain deviation of the gap can be corrected through adjusting the elasticity of the disk spring; and the elastic coefficient of the disk spring is larger than that of common springs, so the compression force is reliable.

Description

technical field [0001] The invention relates to the field of extrusion machine accessories, in particular to an extrusion rod pressing device for an extrusion machine. Background technique [0002] Metal extrusion processing is an important method of pressure processing using the principle of metal plastic forming. Metal ingots are processed into tubes, rods, T-shaped, L-shaped and other profiles at one time through extrusion. Metal extrusion machine is the most important equipment for metal extrusion processing. [0003] Metal extrusion process is a high-quality, high-efficiency, low-consumption, chip-free processing process, which has been more and more widely used in the manufacturing fields of automobiles, machinery, light industry, aerospace, military industry, and electrical appliances. Metal extrusion technology, as an advanced manufacturing technology, has opened up broad prospects for further research and application under the circumstances of rising raw material p...
