Description

Technical Field

[0001] The invention relates to the technical field of parts correction, and in particular to a manual precise correction device for large integrated die castings. Background Art

[0002] In manufacturing, a die casting is a part produced through a process called die casting, which involves injecting molten metal into a mold cavity under high pressure, and then forming a part with a specific shape and size after the metal cools and solidifies.

[0003] In the die-casting production process, die-casting parts often have defects such as deformation due to the influence of various factors. For example, the flow rate and temperature distribution of the molten metal during die-casting are uneven, the cooling rate of the mold is inconsistent, and the external force during the demolding process can all cause the die-casting parts to deform to varying degrees. If these deformations are not corrected, they will affect the subsequent processing accuracy of the die-casting parts and the assembly accuracy with other parts, thereby reducing the quality and performance of the entire product. Therefore, correcting the die-casting parts is an important step to ensure that they meet quality standards and usage requirements.

[0004] The existing orthopedic technology for large integrated die castings has some shortcomings. On the one hand, it is difficult to make orthopedic adjustments accurately according to the surface height of the die casting. There is a lack of a device that can adjust the height of the lifting frame and other components through a screw rod so that the orthopedic components can accurately contact and correct the surface of the workpiece. The existing technology may lack such a flexible and precise height adjustment mechanism, resulting in an inability to adapt well to die castings with different degrees of deformation and shapes. The existing technology is deficient in the multi-directional clamping and fixing of die castings, and cannot perform accurate and effective clamping and fixing, which makes it easy for the die casting to move during the correction process, affecting the correction accuracy.

[0005] Therefore, for the defect type of deformation in integrated die castings, a large integrated die casting manual precision correction device is needed. Summary of the invention
