[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] The following gives specific embodiments.

[0026] Such as Figures 1-5As shown in the figure, a hot-dip galvanized angle steel cutting device includes a workbench 1; a baffle 11 is installed in the middle of the workbench 1; a cutter 12 is rotatably connected to the inner wall of the baffle 11; a connecting plate 13 is fixedly connected to the middle of the baffle 11; a first storage member 14 is fixedly connected to the bottom of the connecting plate 13; a heat conducting sheet 15 is fixedly connected to the bottom wall of the first storage member 14, and the other end of the heat conducting sheet 15 is in contact with the cutter 12; a sieve 16 is threadedly connected to the middle of the first storage member 14; a first connecting pipe 17 is fixedly connected to the side wall of the first storage member 14, and the first connecting pipe 17 is communicated with the first storage member 14; two sets of spring rods 18 are fixedly connected to the inner wall of the first connecting pipe 17; a sliding member 19 is fixedly connected to the output end of the spring rod 18, and the sliding member 19 is slidably arranged on the inner wall of the first connecting pipe 17; an air outlet hole 110 is opened in the middle of the first connecting pipe 17; a top plate 111 is fixedly connected to the middle of the sliding member 19, and the top of the top plate 111 is in contact with the inner wall of the first connecting pipe 17; a second connecting pipe 112 is fixedly connected to the top of the first connecting pipe 17; a second storage member 113 is fixedly connected to the top of the second connecting pipe 112, and the second connecting pipe 112, the first connecting pipe 17 and the second storage member 113 are communicated with each other;During operation, after the staff installs the workbench 1 in the working area, they then place the workpiece to be cut in the middle of the workbench 1 and fix it. After that, they can start the electric push rod in the middle of the workbench 1 and adjust the overall height of the shield 11, so that the rotating cutting tool 12 gradually approaches the workpiece and cuts it. By providing a first storage member 14 at the end of the shield 11, an appropriate amount of liquid can be injected into the inner wall of the first storage member 14 before use. Then, rotate the card sieve 16 to seal the first storage member 14. At the same time, an appropriate amount of coolant can be added to the middle of the second storage member 113. After the cutting tool 12 rotates for a long time and generates a large amount of heat, under the action of the heat conducting sheet 15, the heat can be transferred to the inner wall of the first storage member 14 and contact the liquid. When the liquid is heated and vaporized, the generated gas will push the sliding member 19 to slide towards the side close to the cutting tool 12, and during the sliding process, the output ends of the two spring rods 18 will be squeezed. When the sliding member 19 moves, the top plate 111 will move away from the second connecting pipe 112. Then, the coolant on the inner wall of the second storage member 113 can be transferred to the inner wall of the first connecting pipe 17 through the second connecting pipe 112 and discharged from the edge of the first storage member 14, thus being transferred to the middle of the cutting tool 12. After the sliding member 19 continues to move, the air outlet 110 will communicate with the first storage member 14, and the excess gas inside the first storage member 14 will be discharged. Then, the overall position of the sliding member 19 can be reset again, and this process is repeated in sequence to cool the middle of the cutting tool 12. This step is combined with the first connecting pipe 17 that can continuously discharge coolant to the middle of the cutting tool 12, thereby cooling the middle of the cutting tool 12, reducing the large amount of heat generated by the long-term friction contact between the cutting tool 12 and the workpiece, and preventing the problem of blade deformation when the cutting tool 12 is used in a high-load state for a long time, improving the performance of the cutting tool 12 during subsequent use. By providing the heat conducting sheet 15, the number of times of coolant discharge can be adjusted according to the temperature of the surface of the cutting tool 12, improving the flexibility of coolant discharge.;

[0027] As Figures 3-4As shown, a bracket 2 is fixedly connected to the bottom of the first connecting pipe 17; a fixing plate 21 is fixedly connected to the bottom of the bracket 2, and the middle of the fixing plate 21 is arranged close to the tool 12; a plurality of holes 22 are formed in the middle of the fixing plate 21; two baffle plates 23 are fixedly connected to the side wall of the fixing plate 21, and the middle of the baffle plates 23 is inclined; during operation, by arranging the fixing plate 21 at the bottom of the first connecting pipe 17, when the coolant is discharged, it will first contact the middle of the fixing plate 21, then spread around, and be discharged through the arranged plurality of holes 22. When the coolant spreads, it can be blocked by the two inclined baffle plates 23. With the action of the holes 22, the uniformity and area of the distribution of the coolant in the tool 12 can be improved, thereby improving the cooling accuracy of the tool 12. The two arranged baffle plates 23 can reduce the problem that a large amount of coolant directly overflows outside, reducing the waste of coolant materials.

[0028] As Figure 3 shown, a screw rod 3 is threadedly connected to the middle of the shield 11; a limit block 31 is fixedly connected to the end of the screw rod 3; a pull rope 32 is fixedly connected to the middle of the screw rod 3, and the other end is fixedly connected to the top of the heat conducting sheet 15; during operation, by arranging the screw rod 3 in the middle of the shield 11, when the staff does not use the heat conducting sheet 15, the staff can rotate the screw rod 3 with the help of tools. When the screw rod 3 rotates, the pull rope 32 can be wound around the middle of the screw rod 3, and the wound pull rope 32 can be blocked by the middle of the limit block 31. Then the middle of the heat conducting sheet 15 is pulled up and separated from the middle of the tool 12. With the cooperation of the arranged screw rod 3, the flexibility of the whole heat conducting sheet 15 during operation can be improved. With the action of the limit block 31, the problem that the pull rope 32 becomes loose and disengages when winding around the middle of the screw rod 3 can be reduced, and the phenomenon that the whole pull rope 32 is wound together and is difficult to separate later can be reduced.

[0029] As Figure 4 shown, an elastic rope 4 is fixedly connected to the middle of the baffle plate 23; a counterweight ball 41 is fixedly connected to the middle of the elastic rope 4; during operation, by arranging the elastic rope 4 with elasticity in the middle of the baffle plate 23, when the baffle plate 23 contacts the middle of the tool 12, under the action of resistance, the middle of the baffle plate 23 can shake. Then the middle of the elastic rope 4 will deform and the counterweight ball 41 can hit the middle of the baffle plate 23, and part of the impurities on the middle of the baffle plate 23 can be removed. With the cooperation of the arranged counterweight ball 41, the problem that a large amount of impurities directly accumulate on the middle of the baffle plate 23 and caking occurs, making it troublesome to clean later can be reduced. The elastic rope 4 with elasticity can increase the impact frequency of the counterweight ball 41.

[0030] As Figure 5As shown, a rotating bead 5 is rotatably connected to the end of the sliding member 19; a connecting rope 51 is fixedly connected to the middle of the rotating bead 5, and the other end of the connecting rope 51 is fixedly connected to the inner wall of the first storage member 14; during operation, an observation window 6 is provided in the middle of the sliding member 19, so that during the rotation of the sliding member 19 by the staff, the rotating bead 5 will move synchronously, and under the action of the connecting rope 51, the sliding member 19 will be supported. This step can, under the action of the connecting rope 51, reduce the problem of separation between the sliding member 19 and the first storage member 14 and loss. At the same time, the provided rotating bead 5 can reduce the wear between the sliding member 19 and the connecting rope 51 when the sliding member 19 is rotated.

[0031] As Figure 3 shown, an observation window 6 is fixedly connected to the middle of the first storage member 14; during operation, an observation window 6 is provided in the middle of the first storage member 14, so that the staff can observe the height of the liquid stored inside the first storage member 14 through the observation window 6. This step, in cooperation with the provided observation window 6, can improve the convenience for the staff to observe the liquid height, and at the same time can reduce the problem of trouble caused by difficult viewing when directly adding liquid to the inner wall of the first storage member 14.

[0032] As Figure 5 shown, a plurality of friction patterns 7 are provided in the middle of the sliding member 19, and the plurality of friction patterns 7 are arranged in a circular array; during operation, a plurality of friction patterns 7 are provided in the middle of the sliding member 19, so that when the staff installs the sliding member 19, their hands will first come into contact with the friction patterns 7 for work. This step, under the action of the friction patterns 7, can increase the friction force when the sliding member 19 is rotated later, and at the same time can reduce the problem of slipping when contacting the sliding member 19.

[0033] Working principle: After installing the workbench 1 in the working area, then place the workpiece to be cut on the middle part of the workbench 1 and fix it. After that, the electric push rod in the middle of the workbench 1 can be started, and the overall height of the shield 11 can be adjusted, so that the rotating cutter 12 gradually approaches the workpiece and cuts it. By providing a first receiving member 14 at the end of the shield 11, an appropriate amount of liquid can be injected into the inner wall of the first receiving member 14 before use. Then, rotate the card sieve 16 to block the first receiving member 14. At the same time, an appropriate amount of coolant can be added to the middle of the second receiving member 113. After the cutter 12 rotates for a long time and generates a large amount of heat, under the action of the heat conducting sheet 15, the heat can be transferred to the inner wall of the first receiving member 14 and contact with the liquid. When the liquid is heated and vaporized, the generated gas will push the sliding member 19 to slide towards the cutter 12 side, and during the sliding process, the output ends of the two spring rods 18 will be squeezed. When the sliding member 19 moves, the top plate 111 will move away from the second connecting pipe 112. Then, the coolant in the inner wall of the second receiving member 113 can be transferred to the inner wall of the first connecting pipe 17 through the second connecting pipe 112 and discharged from the edge of the first receiving member 14, thereby being transferred to the middle of the cutter 12. After the sliding member 19 continues to move, the air outlet hole 110 will communicate with the first receiving member 14, and the excess gas inside the first receiving member 14 will be discharged. Then, the overall position of the sliding member 19 can be reset again, and this process is repeated in turn to cool the middle of the cutter 12. By providing a fixing plate 21 at the bottom of the first connecting pipe 17, when the coolant is discharged, it will first contact the middle of the fixing plate 21, and then spread around and be discharged through the multiple holes 22 provided. When the coolant spreads, it can be blocked by the two inclined baffles 23. By providing a screw rod 3 in the middle of the shield 11, when the staff does not use the heat conducting sheet 15, the staff can use tools to rotate the screw rod 3. When the screw rod 3 rotates, the pulling rope 32 can be wound around the middle of the screw rod 3, and the wound pulling rope 32 can be blocked by the middle of the limiting block 31. Then, the middle of the heat conducting sheet 15 is lifted and separated from the middle of the cutter 12. By providing an elastic rope 4 with elasticity in the middle of the baffle 23, when the baffle 23 contacts the middle of the cutter 12, under the action of resistance, the middle of the baffle 23 can shake. Then, the middle of the elastic rope 4 will deform and the counterweight ball 41 can hit the middle of the baffle 23 to remove some impurities in the middle of the baffle 23. By providing an observation window 6 in the middle of the sliding member 19, when the staff rotates the sliding member 19, the rotating beads 5 will move synchronously and support the sliding member 19 under the action of the connecting rope 51. By providing an observation window 6 in the middle of the first receiving member 14, the staff can observe the height of the liquid stored inside the first receiving member 14 through the observation window 6. By providing multiple friction lines 7 in the middle of the sliding member 19,When the staff installs the sliding member 19, their hands will first come into contact with the friction lines 7 for work.
