Description

Technical Field

[0001] This utility model relates to the field of casting automation technology, and in particular to an automatic shell-making line. Background Technology

[0002] In manufacturing, precision casting is a collective term for a series of processes to obtain castings with precise dimensions. Compared with traditional sand casting, it can produce castings with more accurate dimensions and better surface finish. With social development, overhead chain production lines have gradually replaced traditional manual operation modes. At key work nodes in precision casting, the application of robotic arms is particularly important. For example, in the shell-making process, robotic arms can accurately and efficiently grasp and transfer the shell, maintaining a high degree of consistency and accuracy in a series of complex operations such as material application. Automated shell-making lines, through close cooperation with robotic arms, integrate the originally scattered shell-making processes that rely on human experience into automated and standardized processes. This not only greatly improves the production efficiency of shell making and reduces labor costs, but also significantly improves the stability and reliability of product quality, powerfully promoting the precision casting industry towards automation and intelligence. This utility model is an automated shell-making line.

[0003] Existing automated shell-making lines struggle to achieve rapid and stable transfer of raw shell materials or semi-finished products between different processing stations during shell making. The shell mold clamping is unstable, which can easily lead to quality problems such as dimensional deviations and surface defects. Utility Model Content

[0021] This utility model provides an automatic shell-making line, which has the following beneficial effects:

[0022] This utility model includes a clamping arm and a bracket. A fourth hydraulic rod is fixed to the lower end of the sliding seat, and a pressure plate is fixed to the lower end of the piston rod of the fourth hydraulic rod. When clamping the shell mold, firstly, the second hydraulic rod extends, causing the two sets of clamping plates to move towards the side of the shell mold, thus achieving precise and stable clamping of the side of the shell mold. Next, the third hydraulic rod extends, causing the lower ends of the two sets of brackets to firmly support the lower end of the shell mold, providing bottom support for the shell mold. Finally, the fourth hydraulic rod extends, causing the pressure plate to press downwards onto the shell mold. Through this... Through a series of coordinated actions, the shell mold is firmly fixed in both the horizontal and vertical directions. This multi-directional fixing method has extremely high stability, effectively preventing displacement or shaking of the shell mold during subsequent processing due to insecure fixing. It can effectively avoid dimensional deviation problems caused by unstable fixing and ensure the precision requirements of shell mold production. At the same time, it also eliminates quality defects such as surface imperfections that may be caused by shaking or collision, greatly improving the quality level of shell mold products and laying a solid foundation for the high-quality completion of the entire precision casting process.

[0023] Furthermore, this invention features multi-dimensional precise control functions. The operation of the No. 1 motor can precisely adjust the left and right positions of the moving plate to meet the lateral positioning requirements of different working positions, ensuring accurate docking with corresponding equipment or processes at each stage of the shell-making process. When the No. 2 motor is working, the rotating disk can rotate flexibly, and the extension operation of the No. 1 hydraulic rod allows the insertion rod to be inserted into the insertion hole of the rotating disk, thereby achieving stable braking of the rotating disk and effectively eliminating shaking caused by external interference or inertia, ensuring the stability and accuracy of the associated shell-making operations. The activation of the No. 3 motor can finely adjust the height of the lifting seat to adapt to different height levels. The shell-making process plays a crucial role in shell mold handling, placement, or processing at specific heights. Motors No. 4 and No. 5 independently adjust the elevation angles of the connecting arm and movable seat, respectively. This design allows the shell-making tools or actuators to flexibly change angles according to actual process requirements, ensuring more precise and comprehensive shell mold processing. Furthermore, the separate operation of the three drive motors provides the rotating column with multiple speed options, meeting the diverse rotation speed requirements of the shell mold at different process stages. For example, it enables differentiated rotation effects in coating and molding processes, further enhancing the process adaptability and production flexibility of the entire automated shell-making line.
