Wear-resistant gaskets pasted on the surfaces of the first slider 4, the second slider 20 and the third slider 133 can effectively increase the service life of the first slider 4, the second slider 20 and the third slider 133.

[0029] Specifically, the moving mechanism 23 includes a mounting block 231 installed at the bottom of the supporting leg 22, a mounting groove 232 is opened in the middle of the bottom of the mounting block 231, a shock absorber 233 is installed in the mounting groove 232, a universal wheel assembly 234 is fixedly connected to the bottom of the shock absorber 233, threaded grooves 235 are opened on both sides of the mounting block 231, an adjusting screw 236 is threadedly connected in the threaded groove 235, a first ball bearing 237 is specified to be connected to the bottom of the adjusting screw 236, a supporting foot pad 238 is fixedly connected to the bottom of the first ball bearing 237, and an anti-slip pad with anti-slip patterns is pasted to the bottom of the supporting foot pad 238.

[0030] In this embodiment, by setting up the universal wheel assembly 234, the device can be moved more conveniently when it needs to be moved. At the same time, the shock absorber 233 can effectively reduce the vibration during movement. At the same time, by adjusting the adjusting screw 236, the adjusting screw 236 is rotated in the thread groove 235, so that the supporting foot pad 238 contacts the ground. The anti-skid pad with anti-skid patterns on the bottom of the supporting foot pad 238 can effectively prevent slipping and prevent the device from sliding sideways during operation.

[0031] Specifically, the surfaces of the opening and closing door 11 are fixedly connected with handrails 25 and fixed locks 26, and the body of the opening and closing door 11 is made of tempered glass material, and the surface of the handrail 25 is sleeved with a rubber soft sleeve, and the front of the cutting box 2 is equipped with lock grooves corresponding to the fixation.

[0033] Specifically, a bulb assembly 27 is installed on one side of the top of the cutting box 2, a protective shell 28 is fixedly connected to the left side of the motor, and the protective shell 28 is sleeved on the outside of the saw blade 10, and an air suction port 29 is provided on the top of the cutting box 2, and the air suction port 29 is connected to the suction fan assembly 14 through a ventilation pipe 35.

[0034] In this embodiment, the bulb assembly 27 can illuminate the interior of the cutting box 2, allowing people to observe the cutting situation more intuitively. The protective shell 28 can provide a certain protection when the opening and closing door 11 is opened to cut certain objects. The suction port 29 can increase the suction area of ​​the suction fan assembly 14, thereby improving the dust absorption capacity.

[0035] Specifically, the limit locks 30 are fixedly connected to both sides of the front of the clamping frame 18, and the waste box 21 is provided with limit lock 30 rings on both sides corresponding to the limit locks 30, the tool box 31 is fixedly connected to the left side of the operating table 1, and the port of the third electric cylinder 135 is pasted with a rubber gasket with a protrusion.

[0036] In this embodiment, the limit lock 30 can fix the waste box 21 to prevent the waste box 21 from sliding out of the clamping frame 18.

[0037] Specifically, the end of the screw rod 138 is fixedly connected to a second ball bearing 32, the left side of the ball bearing is connected to the front of the installation cavity, the right side of the bottom of the suction fan assembly 14 is fixedly connected to a dust box 33 through a ventilation pipe 35, the bottom of the dust box 33 is provided with an external thread, and the dust box 33 is threadedly connected to a dust bag 34 through the external thread.

[0038] In this embodiment, the second roller bearing can fix the screw rod 138, provide the screw rod 138 with a certain support capacity, prevent the screw rod 138 from twisting, deformation and breakage during long-term use, and increase the service life of the screw rod 138. The dust box 33 is connected to the dust bag 34 through an external thread thread, so as to conveniently and centrally process the sucked dust.

[0039] For example, Figure 1-Figure 6As shown, the working process of the automatic sawing adjustment mechanism of the metal circular saw machine of the embodiment of the present invention is as follows: when in use, adjust the adjustment screw 236 to make the support pad 238 leave the ground. At this time, the universal wheel loses the anti-skid function of the support pad 238, thereby facilitating the movement of the device. After the movement is completed, turn the adjustment screw to prevent slipping, and then turn on the PLC control switch 24. At this time, the PLC control switch 24 controls each part of the device to operate respectively. The required cutting angle and cutting height are input into the PLC control switch 24. At this time, the PLC control switch 24 controls the first electric cylinder 6 to move relative to each other. The shaft 7 is connected to the reinforcing plate 8, so the cutting angle is adjusted by the mutual movement of the first electric cylinder 6. When the desired cutting angle is adjusted, the position sensor 36 transmits a signal to the PLC control switch 24, and the second electric cylinder 16 is extended and retracted, thereby driving the sliding plate 5 to move through the first slider 4, thereby adjusting the height of the first motor 9. When the desired height is reached, the position sensor 36 transmits a signal to the PLC control switch 24, and the PLC control switch 24 controls the second electric cylinder 16 to stop operating. At this time, the object to be cut is placed on the limit plate 134, and the position sensor 36 captures the signal, P The LC control switch 24 controls the third electric cylinder 135 to extend and retract, thereby clamping the cutting material. At this time, the PLC control switch 24 controls the second motor 132 to rotate. The rotation of the second motor 132 drives the screw rod 138 to rotate. The moving nut 136 slides accordingly due to the movement of the screw rod 138, thereby driving the third slider 133 to slide in the third slide groove 131, and then transporting the cutting material to the saw blade 10 through the cutting opening 37 for cutting. When the material reaches the position of the saw blade 10, the position sensor 36 sends a signal to the PLC control switch 24, and the PLC control switch 24 controls the first motor 9 to start, and the second motor 9 starts. The output end of a motor 9 drives the saw blade 10 to rotate for cutting. At this time, larger waste falls from the cutting groove 12 into the waste box 21, and smaller dust is sucked into the dust bag 34 at the bottom of the collection box by the suction fan assembly 14 through the suction port 29, which is convenient for centralized cleaning. When cutting certain specific items and the size of the cutting port 37 is not enough or needs to be cleaned, the fixed lock 26 can be opened, and the opening and closing door 11 can be opened by pulling the handrail 25 for operation. When the bottom needs to be cleaned, the limit lock 30 is opened to extract the waste box 21 for cleaning. The tool box 31 can store required sundries or repair parts and tools.
