[0002] A sawing machine is a machine tool that uses circular saw blades, saw bands or saw blades as tools to saw metal round materials, square materials, pipes and profiles. The saw blade is driven by the driving wheel and the driven wheel. The cutting direction of the saw blade is controlled by the guide rail control frame, and the guide rail control frame is supported by the hydraulic cylinder piston rod to fall into the sawed material. The sawing machine is equipped with manual or hydraulic cylinder clamping and locking mechanisms, as well as hydraulic operating valve switches.

[0023] The following is combined with Figure 1-3 This application is described in further detail.

[0024] The present application embodiment discloses a pressing device for a sawing machine. Figure 1-3 A pressing device of a sawing machine includes a workbench 1, a frame 2 is installed on the workbench 1, a cutting saw 4 is installed on the lower side of the frame 2, the cutting saw 4 is used to cut the workpiece, and pressing components 5 are installed on both sides of the cutting saw 4 on the workbench 1. The pressing components 5 are used to press down the two ends of the workpiece to complete clamping and fixing to prevent the workpiece from deflecting.

[0025] Reference Figure 1 A two-axis feeding system 3 is installed on the frame 2, and the two-axis feeding system 3 drives the cutting saw 4 to move along the Y axis and the Z axis to achieve cutting of the workpiece.

[0026] Reference Figure 2 The cutting saw 4 is composed of a circular saw blade, a tool holder and a power motor for driving the circular saw blade to rotate. The circular saw blade is driven by the power motor to rotate to cut the workpiece.

[0027] Reference Figure 3 The pressing assembly 5 includes a linear actuator 501 installed on the frame 2. The movable end of the linear actuator 501 is connected to a limit pressure plate 502. The limit pressure plate 502 is driven up and down by the linear actuator 501 to clamp the workpiece. The linear actuator 501 can be a servo electric cylinder, a hydraulic rod, etc. as needed.

[0028] Reference Figure 3 The limiting pressure plate 502 includes two hinged plates 5021, the ends of the two hinged plates 5021 are hinged to each other through a damping shaft, a guide groove plate 5022 is installed at one end of the two hinged plates 5021 away from each other, a rubber pad is installed on the lower surface of the hinged plate 5021, the guide groove plate 5022 is hinged to the movable end of the linear actuator 501, and the hinged plate 5021 is driven downward by the linear actuator 501, so that the hinged plates 5021 on both sides abut against the workpiece to clamp the workpiece.

[0029] Reference Figure 3A slide groove is provided on the guide groove plate 5022, and a connecting shaft 5023 is movably installed in the slide groove. The connecting shaft 5023 is fixedly connected to the output end of the linear actuator 501, providing a movable space for folding between the two hinged plates 5021. When the force application point of the linear actuator 501 on the hinged plate 5021 is located above the workpiece, the linear actuator 501 provides a plane downward pressure on the workpiece. When the force application point of the linear actuator 501 on the hinged plate 5021 is located outside the workpiece, the hinged plate 5021 is subjected to the force of the workpiece and the linear actuator 501, and the middle part of the linear actuator 501 is tilted upward and the end is pressed downward to form an oblique clamp, which can prevent the workpiece from moving up and sliding sideways.

[0030] The implementation principle of a pressing device of a sawing machine in the embodiment of the present application is as follows:

[0031] When the workpiece needs to be cut, the operator places the workpiece on the workbench 1, and the downward pressure component 5 is driven by the linear actuator 501 connected to the movable end, so that the limit pressure plate 502 moves up and down to clamp the two ends of the workpiece. When the linear actuator 501 applies pressure to the workpiece, according to the structural characteristics of 5021, a plane downward pressure can be achieved, and an angled clamping can also be formed to prevent the workpiece from moving up and sliding sideways, completing the clamping and fixation to prevent the workpiece from shifting. The two-axis feeding system 3 is activated to drive the cutting saw 4 to move along the Y-axis and Z-axis to achieve cutting of the workpiece. The power motor in the tool holder is started to drive the circular saw blade to rotate to cut the workpiece.
