[0024] Embodiment

[0025] As Figures 1-5 shown, in this embodiment, a down-pressing cutting saw with a safety protection structure includes a base 1. One end of the top of the base 1 is provided with a gantry 2. A cutting mechanism is arranged on the gantry 2. The cutting mechanism includes a cutting frame 4 arranged below the gantry 2. A cutting tool 5 is arranged on the cutting frame 4. One side of the cutting frame 4 is provided with a cutting motor 6 for driving the cutting tool 5 to rotate. The upper end of the gantry 2 is provided with a linear motor 3 for driving the cutting frame 4 to lift and lower. One side of the gantry 2 is provided with a controller 7 electrically connected to the linear motor 3 and the cutting motor 6;

[0026] A protective component is arranged on the side surface of the gantry 2. The protective component includes protective plates 8 symmetrically and movably arranged at both ends of both sides of the gantry 2. Both ends of the upper side of the cutting frame 4 are rotatably connected with guide wheels 12. The side of the protective plate 8 facing the gantry 2 is inclined with a first guide groove 16. The lower end of the first guide groove 16 is vertically provided with a second guide groove 17. And the guide wheels 12 are movably matched with the first guide groove 16 and the second guide groove 17, and are configured such that when the cutting frame 4 drives the guide wheels 12 to displace downward, the two protective plates 8 on the same side approach each other.

[0027] In order to increase the stability and sealing performance between the two protective plates 8 on the same side, receiving grooves 14 are arranged on the opposite sides of the two protective plates 8 on the same side. The receiving grooves 14 are movably connected with inner plates 11. A spring 15 is arranged between one side of the inner plate 11 and the inner wall of the receiving groove 14. And in the initial state of the spring 15, the end of the inner plate 11 away from the spring 15 protrudes from the end of the protective plate 8.

[0028] Furthermore, adaption openings 10 for adapting to workpieces are arranged at the lower ends of the opposite sides of the two protective plates 8 on the same side.

[0029] In order to realize the guiding and fixing of the protective plate 8, fixing plates 9 for fixing the protective plate 8 are arranged at both end parts on the two sides of the gantry 2. A sliding groove 13 adapted to the protective plate 8 is arranged on one side of the fixing plate 9, and the protective plate 8 is in sliding fit with the sliding groove 13.

[0030] Furthermore, an avoidance groove 18 is arranged at the corresponding position of the top of the base 1 and the gantry 2, and the avoidance groove 18 corresponds to the cutting tool 5. A fixing frame 19 corresponding to the avoidance groove 18 is arranged at the bottom of the base 1, and a collecting box 20 with an open top is movably connected to the fixing frame 19.

[0031] In addition, a positioning component is further included. The positioning component includes a fixed seat 21 arranged at one end of the top of the base 1. A screw rod 22 is in threaded fit with the fixed seat 21. A positioning block 23 is arranged at one end of the screw rod 22. A fixed block 24 is fixedly connected to the end of the top of the base 1 far from the fixed seat 21 and corresponding to the positioning block 23.

[0032] Working principle: When in use, the part of the workpiece to be cut is placed directly below the cutting tool 5. At the beginning, the cutting tool 5 is at a certain distance from the workpiece. Then, the screw rod 22 is rotated to drive the displacement of the positioning block 23. The positioning block 23 cooperates with the fixed block 24 to stably position the workpiece. After that, an instruction is input on the controller 7, and then the controller 7 controls the linear motor 3 and the cutting motor 6. The linear motor 3 drives the cutting frame 4 to move downward, and the cutting motor 6 drives the cutting tool 5 to rotate. When the cutting frame 4 moves downward, it drives the protective plate 8 to move through the cooperation of the guide wheel 12 and the first guide groove 16. The protective plate 8 gradually covers the side surface of the gantry 2. Before the cutting tool 5 contacts the workpiece, the inner plates 11 of the two protective plates 8 on the same side first come into contact. Then, as the cutting frame 4 moves downward, the inner plates 11 remain stationary, and the protective plate 8 continues to move a certain distance. As a result, the spring 15 is compressed, and the covering is completed. Subsequently, cutting can be carried out. The inner plates 11 are used to adapt to the workpiece. Moreover, when cutting, the cutting tool 5 rotates and moves downward at the same time. At this time, the guide wheel 12 enters the second guide groove 17, and the protective plate 8 also remains stationary. After cutting is completed, the cutting frame 4 rises, the spring 15 resets, the protective plate 8 drives the inner plates 11 to move away, and the workpiece can be taken off. The chips generated by cutting can fall through the avoidance groove 18 into the collecting box 20 for collection.
