It is an important machining equipment with broad market prospects. Its advancement directly affects the healthy development of various industries related to machining. When sawing aluminum metal sheets, a circular sawing machine is usually used.

[0003] In the patent document with the publication number CN114570998B, a numerically controlled direct drive full-automatic high-speed sawing system is provided. In this device, the sheet is clamped through the cooperation of a feeding clamping block and a feeding reference backstop, and then the sheet is sawed through the cooperation of a torque motor and a sawing power head. However, manual loading is required for each sawing, and after each sawing is completed, the sawn material needs to be conveyed outwards before the next sawing can be carried out. The process of manual loading and the process of waiting for the next sawing both take a lot of time. Sawing and processing are time-consuming and laborious, and the processing efficiency is low. Therefore, a high-efficiency numerically controlled sawing and processing machine for aluminum metal sheets with higher sawing and processing efficiency and more time-saving and labor-saving is proposed.

During use, the user can stack multiple aluminum plates neatly at the feeding end of the cyclic feeding mechanism at one time. By driving the crank-rocker mechanism continuously with the feeding motor, specifically, when the connecting rod swings forward, the L-shaped bracket pushes the materials forward. When the connecting rod swings backward, the aluminum plate at the bottom of the feeding end is taken out. The connecting rod makes reciprocating motion, and at the same time, cyclic material taking and intermittent feeding to the double-station switching mechanism are carried out. The user does not need to perform the feeding operation every time sawing is carried out, saving the feeding time and manpower, and improving the efficiency of sawing processing. Further, the double-station switching mechanism can switch materials, send the already sawn aluminum plates into the discharging mechanism, and at the same time move the unsawn aluminum plates to the lower part of the sawing mechanism, enabling the sawing work and the conveying work to be carried out synchronously, saving the sawing time and further improving the efficiency of sawing processing.
