Problems solved by technology

Because this kind of large solid profile has a large cross-sectional area and the meter weight of the profile is very heavy, when it is extruded on a medium-sized extruder, the extrusion ratio is very small, only 3-4 in many cases, such as figure 1 As shown, it makes it difficult to feed the corner of the profile, and the corner of the extruded profile collapses, and even the corner becomes a large arc.

Embodiment Construction

[0024] see figure 2 and image 3 , figure 2 It is a schematic diagram of the front structure of a new mold for hot extrusion of a large solid profile on a medium-sized extruder of the present invention. image 3 for figure 2 A-A cut-away diagram. Depend on figure 2 and image 3 It can be seen that the new mold for hot extrusion of large solid profiles on the medium-sized extruder of the present invention is formed by superimposing the front deflector 1, the secondary deflector 2 and the die surface 3 successively from front to back.

[0025] see Figure 4 and Figure 5 , Figure 4 It is a schematic diagram of the front structure of the front deflector of the present invention. Figure 5 for Figure 4 The B-B section diagram. Depend on Figure 4 and Figure 5 It can be seen that the front deflector 1 of the present invention includes a first central feed hole 11, and the upper and lower walls of the first central feed hole 11 are divided into two parts: a front...

Abstract

The invention relates to a large-scale solid profile hot extrusion mould of a medium extruder, formed by orderly laying up a front guide plate (1), a secondary guide plate (2) and a mould surface (3) from front to back. The front guide plate (1) comprises a first center material inlet hole (11), and the upper hole wall and the lower hole wall of the first center material inlet hole (11) consist of a front straight hole wall (111) and a back inclined hole wall (112), the back inclined hole wall (112) is gradually extended from front to back, the left hole wall (113) and the right hole wall (113) form an inclined hole wall shape, and the inclined hole wall is gradually extended. The secondary guide plate (2) comprises a second center material inlet hole (21), and the second center material inlet hole (21) is in a dumbbell shape. The center part of the second center material inlet hole (2) is adjacent to a mould cavity of the mould surface, and the left end and the right end are extended. The mould surface (3) comprises a guide pit (31) and the mould cavity (32), the upper pit wall (311) and the lower pit wall (311) form an inclined surface shape, and the inclined surface is tapered.The invention can guarantee the sufficient material supply of large-scale solid profile angle positions, can effectively increase extruding force, and guarantee the density and the strength of profiles.

Description

(1) Technical field [0001] The invention relates to a die, in particular to a new die for hot extrusion of a large solid profile on a medium-sized extruder. The invention belongs to the technical field of aluminum alloy extruded profile mold processing. (2) Background technology [0002] Because aluminum alloy extruded profiles have many advantages such as low density, high strength, easy processing, simple repair and maintenance, and good economy, environmental protection and recyclability, aluminum alloy extruded profiles are widely used in various fields. The application is more and more extensive. It turns out that many large stress components are gradually replacing steel with aluminum alloy. Since there are not many large extrusion machines in China at present, many large solid profiles have to be extruded on medium-sized extrusion machines. Because this kind of large solid profile has a large cross-sectional area and the meter weight of the profile is very heavy, w...
