DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to solve the technical problem that when the blades of the disc cutter 1 66 and the disc cutter 2 69 are broken, it is not possible to find them in time, resulting in poor cutting effect of the batch metal sheet 40, such as Figure 1 - Fig.14 As shown, the following preferred technical solutions are provided: A construction cutting device comprises a mounting plate 1 and a plurality of guide rollers 2 rotatably mounted on the mounting plate 1, which are used to guide materials and prevent the materials from running off the track during shearing. The mounting plate 1 is also provided with a plurality of pairs of tensioning mechanisms 3, which can adjust the tension during material transmission to ensure the normal transmission of materials. A base 4 and a load-bearing plate 9 are fixedly arranged on the outer wall of one side of the mounting plate 1, respectively, which can support and fix the parts on the equipment. A plurality of power assemblies 8 are fixedly arranged on the base 4 for providing power output. A pair of guide assemblies 5 are fixedly arranged on the load-bearing plate 9, which also guide the materials. A shearing assembly 6 is also fixedly arranged on the load-bearing plate 9. The two guide assemblies 5 are respectively arranged on both sides of the shearing assembly 6, and the shearing assembly 6 shears the materials. A plurality of power assemblies 8 are respectively connected to the guide assemblies 5 and the shearing assembly 6 for transmission, so as to transmit the power on the power assemblies 8 to the guide assemblies 5 and the shearing assembly 6, so as to achieve the guiding effect and shearing effect on the materials.

[0022] The metal sheet 40 is sequentially transmitted and arranged on the guide roller 2, the tensioning mechanism 3, the guide component 5 and the shearing component 6. A plurality of detection components 7 are fixedly arranged on the shearing component 6 for detecting whether the shearing component 6 has a broken edge phenomenon, so as to prevent the metal sheet 40 from having a poor continuous cutting effect and the problem of the metal sheet 40 being cut continuously. A plurality of grinding components 10 are fixedly installed on the top surface of the load-bearing plate 9, which are mainly used for grinding the cut of the metal sheet 40. The grinding component 10 is respectively fixedly arranged with a flipping shearing mechanism 20 and a sensing component 30. When the shearing component 6 has a broken edge, resulting in the metal sheet 40 not being cut, the adhesion part will trigger the sensing component 30 during the continuous movement of the metal sheet 40. After being triggered, the sensing component 30 will start the flipping shearing mechanism 20 to cut the adhesion part of the metal sheet 40 for a second time, so as to ensure that the shearing component 6 can still completely cut the metal sheet 40 in the case of a broken edge, maintain a good shearing effect, and thus avoid the situation of poor shearing effect in large quantities.

[0023] The shearing assembly 6 includes a pair of support frames 61 fixedly mounted on the top surface of the load-bearing plate 9, and electric telescopic columns 62 are fixedly mounted on the tops of the two support frames 61. The output ends of the two electric telescopic columns 62 penetrate the top walls of the support frames 61, and the output ends of the two electric telescopic columns 62 are respectively fixedly connected to mounting plates 63. A rotating shaft 1 65 is rotatably mounted on the two mounting plates 63, and a plurality of disc knives 1 66 are sleeved on the rotating shaft 1 65. A driven gear 67 is fixedly connected to the side wall of the rotating shaft 1 65 near the end of the power assembly 8. A rotating shaft 2 68 is rotatably mounted on the lower ends of the two support frames 61, and a plurality of disc knives 2 69 are sleeved on the rotating shaft 2 68. A driving gear 620 is fixedly connected to the side wall of the rotating shaft 2 68 near the end of the power assembly 8, and the driving gear 620 and the driven gear 67 are meshedly connected, and when the rotating shaft 2 68 and the disc knife 2 69 rotate synchronously, the rotating shaft 1 65 and the disc knife 1 66 can be driven to rotate synchronously through the driving gear 620 and the driven gear 67. When the metal plate 40 passes through the gap between the blade of the disc knife 1 66 and the blade of the disc knife 2 69, the metal plate 40 can be sheared. The electric telescopic column 62 can drive the mounting plate 63, the rotating shaft 1 65 and the disc knife 1 66 to move in the vertical direction, which is convenient for later maintenance and material replacement. A plurality of load-bearing rods 64 are fixedly connected between the two mounting plates 63. A plurality of detection components 7 are fixedly sleeved on the load-bearing rods 64 for detecting the blades of the disc knife 1 66 and the disc knife 2 69 to determine whether there is a collapse at the blade and the wear of the blade.

[0024] The power assembly 8 includes a driving motor 81 fixedly mounted on the base 4. The driving motor 81 is connected to the two guide assemblies 5 via belts 82 for driving the guide assemblies 5 to rotate to guide and convey the metal sheet 40. The driving motor 81 is connected to the driving gear 620 via belts 82. The driving motor 81 can drive the rotating shaft 2 68 and the disc knife 2 69 to rotate synchronously via the belts 82 and the driving gear 620.

[0025] The detection component 7 includes a U-shaped frame 71 fixedly mounted on the load-bearing rod 64, an electric lifting rod 72 is fixedly installed on the side wall of the inner cavity of the U-shaped frame 71, and a detection head 73 is fixedly installed at the output end of the electric lifting rod 72 for detecting whether there is a chip on the blade of the disc knife 1 66 and the disc knife 2 69 and the wear of the blade, and the electric lifting rod 72 is used to adjust the position of the detection head 73 so that the detection head 73 can always detect the blade of the disc knife 1 66 and the disc knife 2 69.

[0026] The U-shaped frame 71 includes a U-shaped frame body 711, and a movable groove 712 is opened on the side wall of the inner cavity of the U-shaped frame body 711. A micro switch 713 is arranged in the inner cavity of the movable groove 712. The mounting end of the electric lifting rod 72 is embedded and rotatably installed in the inner cavity of the movable groove 712. When a crack occurs at the blade of the disc knife 1 66 or the disc knife 2 69, a thrust will be generated on the detection head 73. Under the action of the thrust, the detection head 73 will drive the electric lifting rod 72 to rotate in the inner cavity of the movable groove 712. During the rotation of the electric lifting rod 72, the micro switch 713 will be triggered, thereby shutting down the equipment.

[0027] The detection head 73 includes a protective shell 731 fixedly mounted on the output end of the electric lifting rod 72, a slideway 732 is provided inside the protective shell 731, a T-shaped slider 736 is inserted and slidably installed inside the slideway 732, the side wall of the T-shaped slider 736 is elastically connected to the side wall of the inner cavity of the slideway 732 through a first spring 733, a first contact 734 is fixedly mounted on the side wall of the T-shaped slider 736, and a second contact 735 is fixedly mounted on the side wall of the inner cavity of the slideway 732. The first contact 734 and the second contact 735 are fixedly mounted on the side wall of the inner cavity of the slideway 732. The second contact points 735 are arranged in alignment, and a slide groove 737 is provided inside the T-shaped slider 736. A push rod 738 is slidably installed inside the slide groove 737. The push rod 738 and the slide groove 737 are elastically connected by a second spring 739. A ball 7320 is rotatably installed in the end of the push rod 738 away from the second spring 739. The ball 7320 is made of a material with high hardness and wear resistance. The ball 7320 corresponds to the blade of the disc knife 1 66 and the blade of the disc knife 2 69.

[0028] Specifically, in the initial state, the ball 7320 is against the side wall of the blade of the disc knife 66. At this time, the compression of the second spring 739 by the push rod 738 reaches the maximum compression state. When the disc knife 66 rotates during the shearing process, the ball 7320 will also rotate on the push rod 738, and the push rod 738 will continue to reach the maximum compression state against the second spring 739. If a chip appears at the blade of the disc knife 66, when the chip rotates to the position of the ball 7320, due to the thin diameter of the push rod 738 and the high hardness, under the elastic force of the second spring 739, the push rod 738 and the ball 7320 will quickly pass through the chip, and at this time, the disc knife 66 will be compressed. The disc knife 1 66 will generate an obstruction, and at the same time, the disc knife 1 66 will generate a thrust on the push rod 738. Under the action of the thrust, the push rod 738 will drive the electric lifting rod 72 to rotate in the inner cavity of the movable groove 712. The electric lifting rod 72 will trigger the micro switch 713 during the rotation of the electric lifting rod 72, and then the equipment will be shut down. After the shutdown, the operator will repair the collapsed part and then start the machine again. The detection method of the disc knife 2 69 is the same as the above, and will not be repeated here. Through the above-mentioned setting, when a collapse occurs at the blade of the disc knife 1 66 or the disc knife 2 69, it can be detected immediately, and the equipment can be shut down for maintenance, which can prevent the phenomenon of poor cutting effect of large quantities of metal plates 40.

[0029] Furthermore, after the disc knife 66 shears the metal sheet 40 for a period of time, the blade of the disc knife 66 will wear and become blunt. If it continues to become blunt, the metal sheet 40 cannot be cut or is cut incompletely. During the shearing process, when the blade of the disc knife 66 is worn, the electric lifting rod 72 is started to extend an appropriate length so that the ball 7320 will not separate from the blade of the disc knife 66, thereby continuously detecting the collapse. Since the top rod 738 always reaches the maximum compression state of the second spring 739, and because the blade of the disc knife 66 is worn, the electric lifting rod 72 moves with the ball 7320 from the relatively thin blade toward the center of the disc knife 66. During the process, the thickness is constantly increasing. Therefore, under the action of force, the T-shaped slider 736 will move towards the direction close to the second contact point 735. As the blade wear of the disc knife 66 continues to increase, the electric lifting rod 72 moves with the ball 7320 for a longer and longer distance, and finally makes the first contact point 734 contact the second contact point 735. At this time, it is judged that the disc knife 66 has reached the maximum degree of wear, the equipment is shut down and the disc knife 66 is replaced. The method for judging whether the disc knife 69 has reached the maximum wear is the same as above, and will not be repeated here. Through such a setting, the situation where the metal plate 40 cannot be cut or is incompletely cut due to blade wear can be reduced, the yield rate is improved, and it is beneficial to the later construction use.

[0030] In order to solve the technical problem of burrs on the cut edge of the metal sheet 40, as Fig.10 and Fig.12 - Fig.14 As shown, the following preferred technical solutions are provided: The grinding assembly 10 includes a base 101 fixedly mounted on the top surface of the load-bearing plate 9, and a grinding head 102 is fixedly mounted on the top surface of the base 101. The sheared metal sheet 40 will pass through the inside of the grinding head 102. During the passage of the metal sheet 40, the grinding head 102 will grind the cut of the metal sheet 40 to prevent burrs from appearing, causing harm to construction workers and inconvenience in use during the construction process.

[0031] The grinding head 102 includes an I-shaped block 1021 fixedly mounted on the top surface of the base 101, a pair of square grooves 1022 are respectively provided on the top surface and the bottom surface of the inner cavity of the I-shaped block 1021, a pair of connecting rods 1023 are embedded and slidably installed in the inner cavity of the square groove 1022, one of the connecting rods 1023 is elastically connected to the side wall of the inner cavity of the square groove 1022 by a third spring 1024, a push rod 1025 is fixedly installed on the side wall of the other connecting rod 1023, and a grinding plate 1026 is commonly fixedly connected to one end of the two connecting rods 1023 away from the square groove 1022, a plurality of pairs of L-shaped fixing plates 1027 are respectively fixedly mounted on the top surface and the bottom surface of the inner cavity of the I-shaped block 1021, a friction wheel 1028 is rotatably mounted on the L-shaped fixing plate 1027, and a plurality of shifting rods 1029 are fixedly installed on the side wall of one end of the friction wheel 1028 close to the grinding plate 1026.

[0032] Specifically, when the sheared metal sheet 40 passes through the gap between the upper and lower friction wheels 1028, it will drive the two friction wheels 1028 and the rotating lever 1029. During the rotation process, the friction wheel 1028 will push the push rod 1025 and the connecting rod 1023 to slide in the inner cavity of the square groove 1022 through the lever 1029 and compress the third spring 1024. The friction wheel 1028 continues to rotate. When it rotates to the gap between the two levers 1029, the elastic force of the third spring 1024 will push the connecting rod 1023 and the push rod 1025. 5 reset, and in this way, the connecting rod 1023 can make a reciprocating motion inside the square groove 1022. Since the connecting rod 1023 makes a reciprocating motion inside the square groove 1022, the grinding plate 1026 can also make a reciprocating motion. Since the cutout of the metal plate 40 is closely attached to the grinding plate 1026, the grinding plate 1026 can reciprocate and grind the cutout of the metal plate 40 during the reciprocating motion, thereby removing the burrs at the cutout of the metal plate 40, reducing the probability of injury to personnel, and facilitating the use in the later construction.

[0033] In order to solve the technical problem that the blade of the disc knife 1 66 or the disc knife 2 69 is broken, resulting in some parts of the metal plate 40 not being sheared off, affecting the use of the subsequent construction process, such as Figure 4 , Figure 6 and Fig.10 - Fig.11 As shown, the following preferred technical solutions are provided: The sensing component 30 includes an L-shaped bracket 301 fixedly mounted on the side wall of the base 101, an embedded groove 302 is provided on the top surface of the L-shaped bracket 301, a moving block 303 is embedded and slidably installed in the inner cavity of the embedded groove 302, the moving block 303 is elastically connected to the side wall of the inner cavity of the embedded groove 302 through a fourth spring 305, a pair of first connecting ears 304 are fixedly mounted on the top surface of the moving block 303, and second connecting ears 306 are fixedly mounted on both sides of the opening of the embedded groove 302, and two first connecting ears 304 are fixedly mounted on the top surface of the moving block 303. A paddle 307 is rotatably mounted on the two connecting ears 306, and the lower end of the paddle 307 is rotatably mounted on the two first connecting ears 304. A pair of arc grooves 308 are opened on the side wall of the inner cavity of the embedded groove 302. The moving block 303 is embedded and slidably mounted in the inner cavity of the arc groove 308. A third contact 309 is fixedly mounted on the side wall of the moving block 303, and a fourth contact 320 is fixedly mounted on the side wall of the inner cavity of the embedded groove 302. The third contact 309 is lower than the height of the fourth contact 320 in the vertical direction.

[0034] The flipping and shearing mechanism 20 includes mounting ears 201 respectively fixedly mounted on the top and bottom surfaces of the I-shaped block 1021, a flipping rod 202 is rotatably mounted on the mounting ear 201, a disc knife 203 is rotatably mounted on the end of the flipping rod 202 away from the mounting ear 201, a fixing frame 205 is fixedly mounted on the outer wall of the mounting ear 201, a rotating motor 204 is fixedly mounted on the fixing frame 205, and the output end of the rotating motor 204 passes through the side wall of the mounting ear 201 and is fixedly connected to the flipping rod 202.

[0035] Specifically, in the initial state, under the limiting action of the fourth spring 305, the paddle 307 is always in a vertical state. When a chip appears at the blade of the disc knife 1 66 or the disc knife 2 69, resulting in some parts of the metal plate 40 not being sheared off, the uncut adhesion parts of the metal plate 40 will generate a thrust on the paddle 307 during the movement. Under the action of the thrust, the paddle 307 begins to flip and drives the moving block 303 to slide in the inner cavity of the arc groove 308. After sliding for a distance, the third contact 309 contacts the fourth contact 320. At this time, two symmetrical rotating motors 204 are started, and at the same time, the two disc cutters 203 are driven to flip towards the direction close to the metal plate 40 through the two flip rods 202. When the uncut adhesion part of the metal plate 40 passes through the gap between the blades of the two disc cutters 203, the two disc cutters 203 can perform a secondary cutting on the uncut adhesion part of the metal plate 40, and completely cut the metal plate 40 to prevent it from affecting its use in subsequent construction processes. After the shearing is completed, the cutting port can be polished smooth by the subsequent polishing component 10.
