Device for assisting in changing of extrusion container of horizontal extruder and using method of device

Abstract

The invention belongs to the technical field of metal extrusion processing, and particularly relates to a device for assisting in changing of an extrusion container of a horizontal extruder and a using method of the device. The device is characterized in that a cuboid U-shaped tank (5) of which the front, the rear and the top are opened is mounted on a trolley (3) with wheels, the U-shaped tank is mounted above the trolley through four down-feed screws, and the height of the U-shaped tank (5) is adjusted through the down-feed screws (4); and a plurality of horizontal roller beds (6) are mounted on the bottom surface of the inside of the U-shaped tank (5), a plurality of guiding rollers (7) are respectively mounted on two sides of the inside of the U-shaped tank (5), and a horizontal lead screw (8) is mounted on the guiding rollers (7), and is adjusted to enable the guiding rollers (7) to move transversely, so that the extrusion container is fixed. The using method of the device is simple and easy to operate. Compared with a method for directly hoisting the extrusion container by using a crane, the using method shortens mounting time; and abrasion of an extrusion container jacket and an extrusion container seat can be reduced effectively.

Description

[0001] Patent field [0002] The invention belongs to the technical field of metal extrusion processing, and in particular relates to a device for assisting a horizontal extrusion machine in extruding cylinder replacement and a method for using the same. Background technique [0003] Metal extrusion processing is an important method of pressure processing using the principle of metal plastic forming. It is mainly used for extrusion blanking of metal materials, or for multi-variety and small-batch production. Metal ingots are extruded into Tube, rod, T-shape, L-shape and other profiles. When the extrusion machine is mainly used in multi-variety and small-batch production, it is generally necessary to be equipped with extrusion barrels of multiple specifications. In actual production, when the alloy type or specification of the product changes, it is often necessary to replace the extrusion barrel. The conventional way to replace the extrusion barrel of a horizontal extrusion m...

AI Technical Summary

Problems solved by technology

When using the crane to hoist the extrusion cylinder, in the process of using the extrusion shaft to push the extrusion cylinder into the extrusion cylinder seat, because the extrusion cylinder seat hinders the movement of the crane sling, it is necessary to change the position on the crane sling. The connection position between the lifting screw and the lifting screw hole on the extrusion cylinder is very difficult. The extrusion cylinder is easy to get stuck on the extrusion cylinder seat. Once the extrusion cylinder is stuck on the extrusion cylinder seat, the extrusion cylinder needs to be taken out , reinstallation, the installation needs to be repeated, and it will cause wear between the extrusion cylinder and the extrusion cylinder seat, and the installation time is as long as 3 to 4 hours

Especially when the center of the extrusion cylinder hoisting screw hole, the center of gravity of the extrusion cylinder and the center of the positioning groove of the extrusion cylinder are not in a straight line, it is more difficult to hoist the extrusion cylinder with the crane
