Problems solved by technology
[0003] However, the existing hot extrusion experimental equipment can only be extruded within a fixed extrusion parameter or a limited range of extrusion parameters. In order to find a suitable Extrusion parameters need to be tested many times under different parameters such as extrusion rate, extrusion temperature, extrusion ratio, etc., which greatly reduces the experimental efficiency

The invention discloses a gradient hot extrusion device capable of continuously changing the extrusion rate, the extrusion temperature and the extrusion ratio. The gradient hot extrusion device comprises a base, an extrusion box, positioning frames, an extrusion assembly, a feeding cover plate, a power assembly, adjusting assemblies, a heating assembly and a computer control system. The top of the base is fixedly provided with the extrusion box, one side of the base is provided with the power assembly, the side part of the extrusion box is provided with the feeding cover plate, the other side of the base is provided with the computer control system and the positioning frames, the interior of the base is provided with the heating assembly, the extrusion assembly is arranged between the positioning frames, and the periphery of one side of the extrusion assembly is provided with the adjusting assemblies. When the device is used, the movement speed of the power assembly, the heating mode and the heating temperature of the heating assembly and the combination mode and the movement speed of the adjusting assemblies can be adjusted through the computer control system, and therefore continuous changes of three extrusion parameters including the extrusion rate, the extrusion temperature and the extrusion ratio are achieved, an extrusion sample with one or more continuously changed parameters is obtained at a time, and the experiment efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of experimental equipment, in particular to a gradient hot extrusion device with continuously variable extrusion rate, extrusion temperature and extrusion ratio. Background technique [0002] Hot extrusion is a commonly used metal material processing method. It can be used as an intermediate or final process in the material processing process. It is often used in steel, aluminum alloy, magnesium alloy and other metal materials such as bars, profiles, wires and other products; hot extrusion The process is carried out in the extrusion device, and the quality of the extruded product directly depends on the selection of the parameters of the extrusion device during the extrusion process. The main extrusion parameters include extrusion rate, extrusion temperature and extrusion ratio. Ideal extrusion effects can only be obtained within the range of specific extrusion parameter combinations. [0003] However, the ...
