Description

Technical Field

[0001] The utility model relates to the field of precision drawing machines, in particular to a precision drawing machine for light alloy profiles. Background Technique

[0002] As light metal structural materials, magnesium alloys and aluminum alloys are increasingly widely used in fields such as automobiles, rail transit, aerospace, and national defense. In order to better meet the diverse needs of products and reduce the secondary processing volume of profiles, the cross-sectional shapes of light alloy profiles are becoming more and more complex, and the precision requirements for profiles are getting higher and higher, such as cross-sectional dimension tolerances, straightness, and twist. Extrusion forming is one of the main methods for processing light alloy profiles. During the extrusion forming process, uneven metal flow is often caused by factors such as the non-uniformity of the internal structure of the blank, the difference in temperature distribution, and die design. In addition, due to the action of external forces after extrusion and uneven cooling rates, the products are bent or twisted. To obtain qualified-sized and flat extruded profiles, they must be corrected.

[0003] According to the publicly disclosed patent 201420442584.3 for a precision drawing machine for light alloy profiles, it includes a machine base, a finishing platform, a transmission device platform, a transmission device, a precision drawing die device, and a clamping die device. The finishing platform and the transmission device platform are installed on the machine base. The transmission device platform is provided with guide rails, and the transmission device is movably installed on the guide rails. The precision drawing die device is installed on the finishing platform, and the clamping die device is installed on the transmission device. The structure of the utility model is simple. The precision drawing die device clamps the profile to be corrected, and the clamping die device clamps the end of the profile. The transmission device is started, and the transmission device drives the clamping die device to move along the guide rails. As the clamping die device moves, the profile is withdrawn from the precision drawing die device, and the precision drawing die device corrects the profile. The precision drawing die device is designed strictly in accordance with the requirements of the cross-sectional dimension tolerances of the profile. During the process of correcting the profile, it can perform extrusion correction on the parts larger than the dimension tolerances, so that the cross-sectional dimensions, straightness, and twist of the profile meet the high-precision dimension tolerance requirements. In the process of implementing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although by seeking. For profiles that have been bent or twisted, as the clamping die device moves, the profile is withdrawn from the precision drawing die device, and the precision drawing die device corrects the bent or twisted profile, improving the straightness and twist of the profile. Moreover, this extrusion correction method will not cause problems such as scratching the product surface compared with traditional roller straightening. However, in the process of use, the traditional precision drawing machine for light alloy profiles can only perform precision drawing on one light alloy profile at a time, resulting in low precision drawing efficiency for light alloy profiles. Workers need to repeatedly replace single light alloy profiles, which is very inconvenient and wastes a lot of time of the workers. Therefore, new technical solutions need to be designed to solve this problem. Content of the Utility Model
