Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 As shown, a safety protection device for a four-column hydraulic cutting machine comprises a cutting machine platform 1 and a lifting knife seat 2 installed on the upper surface of the cutting machine platform 1, a material feeding port 3 is arranged between the upper surface of the cutting machine platform 1 and the lifting knife seat 2, four guard plates 4 are fixedly connected to the four corners of the upper surface of the cutting machine platform 1, a mounting plate 5 is fixedly connected to the front surface of the lifting knife seat 2, and a plurality of protection units 6 are arranged on the front surface of the mounting plate 5. If all the protection units 6 are to be disassembled, the screws connected to the lifting knife seat 2 can be unscrewed, and the mounting plate 5 and the entire protection unit 6 can be repaired. Disassembly, the protection unit 6 includes a base plate 61 fixedly connected to the front surface of the mounting plate 5, a rubber sleeve 62 is provided on the lower surface of the base plate 61, a buffer spring 63 is provided inside the rubber sleeve 62, the lower end of the rubber sleeve 62 is fixedly connected to a bonding plate 64, the inside of the buffer spring 63 extends to the upper surface of the base plate 61 and is provided with a disassembly mechanism 65, the disassembly mechanism 65 includes a bolt 651 passing through the upper and lower surfaces of the base plate 61, a nut 652 is threadedly connected to the outer cylindrical surface of the upper end of the bolt 651, and a support slide rod 653 is fixedly connected to the upper surface of the bonding plate 64 through the inside of the bolt 651.

[0022] By adopting the above technical solution, when the lifting knife seat 2 of the cutting machine descends for cutting, the protective unit 6 that falls on the upper surface of the cutting pad retracts. When retracting, the bonding plate 64 contacts the upper surface of the cutting pad. As the lifting knife seat 2 descends, the buffer spring 63 is compressed, and the support slide rod 653 can slide inside the bolt 651 to provide a supporting effect.

[0023] like Figure 1 and Figure 4 As shown, a feed plate 7 is rotatably connected to the upper side of the front surface of the cutting machine platform 1, support rods 8 are rotatably connected to the outer surfaces of both sides of the feed plate 7, and fixed buckle rods 9 are fixedly connected to the outer surfaces of both sides of the cutting machine platform 1.

[0024] Furthermore, a receiving plate 10 is rotatably connected to the lower side of the front surface of the cutting machine platform 1, folding curtains 11 are fixedly connected to both sides of the rear surface of the receiving plate 10, a hook 12 is fixedly connected to the rear side of the upper end of the folding curtain 11, and a fixing buckle for the hook 12 to be hung is fixedly connected to the front surface of the cutting machine platform 1.

[0026] Working principle: When using the safety protection device of the four-column hydraulic cutting machine, first, when the lifting knife seat 2 of the cutting machine descends for cutting, the protection unit 6 that falls on the upper surface of the cutting pad retracts. When retracting, the bonding plate 64 contacts the upper surface of the cutting pad. As the lifting knife seat 2 descends, the buffer spring 63 is compressed, and the support slide bar 653 can slide inside the bolt 651 to provide a supporting effect. The plug-in effect of the support plug rod 8 is disconnected, and the feeding plate 7 can be folded. The hanging effect of the hook 12 is disconnected, and the folding curtain 11 can be stored. Then, the receiving plate 10 is brought close to the front surface of the guard plate 4, and the hanging rod 13 is twisted to buckle the hanging rod 13 inside the buckle seat 14, so that the receiving plate 10 can be stored and fixed. This is the working principle of the safety protection device of the four-column hydraulic cutting machine.
