Problems solved by technology

[0003] The replacement of the extruding barrel assembly in the prior art mainly relies on manual operation. During the replacement, the old inner lining is replaced with a new inner lining. Extruders with small tonnage, extrusion cylinder specifications and weight, and cannot easily adjust the axial and radial directions of the inner liner and outer casing, and cannot meet the positioning requirements of the inner liner

Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] Such as Figure 1 to Figure 5 As shown, the present invention discloses a positioning device for an extrusion cylinder assembly having an inner liner 31 and an outer sleeve 32 nested therein. It includes a lifting device that is fixedly connected with the inner liner 31 of the extrusion cylinder and can lift the inner liner 31 , and also includes an adjusting device that is connected with the outer shell 32 and can drive the outer shell 32 to rotate relative to the inner liner 31 . The hoisting device is used to lift the inner liner 31, and it has a force-bearing surface 18 perpendicular to...

Abstract

The invention discloses a container assembly positioner which comprises a hoisting device which is fixedly connected with an inner liner of a container and can hoist the inner liner and also comprises an adjusting device which is connected with a jacket and can drive the jacket to rotate relative to the inner liner. The adjusting device contains a force application device which applies a force on the hoisting device so as to change the axial distance of the inner liner relative to the jacket. By the container assembly positioner, radial adjustment of the jacket and the inner liner and axial adjustment of the jacket can be realized so as to meet axial and radial positioning requirements of the inner liner, and the structures of the inner liner and the jacket can be simplified.

Description

technical field [0001] The invention relates to the field of extrusion machines, in particular to a positioning device for an extrusion barrel assembly. Background technique [0002] The extrusion barrel is the working chamber for extruding metal, and it is the container for the ingot during the extrusion process, which is subjected to high temperature and high pressure, and is a large component made of heat-resistant tool steel. During the extrusion process, the temperature of the extrusion cylinder reaches above 500°C, and the unit pressure is high, so the working conditions of the extrusion cylinder are harsh. In order to make the stress on the inner and outer walls of the extrusion cylinder uniform, multi-layer extrusion cylinders are generally used. Existing extruding cylinders generally consist of an inner liner and an outer sleeve, the inner liner is nested in the outer sleeve, and the two are in a coaxial state. Both the inner lining and the outer jacket are cylind...
