Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy tube extrusion, in particular to an aluminum alloy rod extrusion device. Background Art

[0002] Aluminum alloy has the characteristics of high specific strength, high specific stiffness, good plasticity, good thermal conductivity and easy recycling. It is the most widely used type of non-ferrous metal structural material in industry. Extrusion dies are important tools in the forming process of aluminum alloy pipes.

[0003] When aluminum alloy is extruded, the high-temperature aluminum alloy rod needs to be slowly aligned with the aluminum alloy extrusion die to extrude the aluminum alloy rod into an aluminum alloy profile with a uniform shape. However, the following problems exist: since the aluminum alloy rod is extruded in a groove, impurities adhered to the outside of the aluminum alloy rod fall into the groove during extrusion. If the impurities in the groove are not cleaned in time, the impurities on the round tube will be squeezed into the round tube, thereby affecting the quality of the aluminum alloy tube forming.

[0004] After searching, the application number is: CN 202122975825.3. The aluminum column contacts the first pressure ring and the second pressure ring, and the first pressure ring is supported by the discharge fixed block, which effectively improves the accuracy of the equipment operation to improve the quality of the product. However, impurities in the aluminum alloy are easy to fall into the groove, which affects the quality of the aluminum alloy pipe forming during subsequent extrusion. Another example is the application number: CN202221744995.9. Although it can clean the surface of the aluminum alloy pipe before extrusion, when debris falls into the groove, the debris in the groove cannot be cleaned, resulting in impurities on the round tube being squeezed into the round tube, thereby affecting the quality of the aluminum alloy pipe forming. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, when impurities fall into the groove during extrusion, if the impurities in the groove are not cleaned in time, the impurities on the round tube will be squeezed into the round tube, thereby affecting the quality of aluminum alloy tube forming.

[0031] When the aluminum alloy column 5 moves toward the aluminum alloy mold 12, the spring 16 is slowly compressed until the pressure plate 17 is close to the limit shell 14, thereby limiting the aluminum alloy mold 12 from continuing to move to the left, making it easier to extrude the aluminum alloy column 5. When the extrusion is completed, the spring 16 drives the pressure plate 17 to move to the right, thereby driving the aluminum alloy mold 12 to move to the right.

[0032] A limiting mechanism 8 for limiting the rightward movement of the aluminum alloy mold 12 is arranged on the right side of the aluminum alloy mold 12. The limiting mechanism 8 includes a turntable 801, which is rotatably connected to the right side wall of the support frame 7 through an axis.
