[0040] This application provides a steel cutting device.

[0041] like Figures 1 to 3 As shown, a steel cutting device includes:

[0042] A CNC saw 1 is used for cutting steel. The CNC saw 1 includes a feed inlet and a discharge outlet. The CNC saw 1 in this embodiment is a fully automatic CNC saw 1, which can clamp and transport the incoming material, and after accurately cutting the incoming material according to the cutting length, transport the cut steel to the discharge outlet.

[0043] The loading mechanism 2 is located on one side of the feed inlet of the CNC sawing machine 1. The loading mechanism 2 includes a placing rack 3, a transfer assembly 5, and a feeding rack 4. The placing rack 3 is used to place several parallel steel pieces. The transfer assembly 5 is used to transfer one steel piece from the placing rack 3 to the feeding rack 4. The feeding rack 4 is used to transport the steel piece along a first direction to the feed inlet of the CNC sawing machine 1. The conveying direction of the feeding rack 4 is parallel to the length direction of the steel piece.

[0044] The discharge mechanism 6, located on one side of the discharge port of the CNC sawing machine 1, is used to receive the material after it has been cut by the CNC sawing machine 1 and to transport the cut material away from the discharge port of the CNC sawing machine 1. The discharge mechanism 6 consists of a drive assembly and a conveying roller, and the conveying direction of the discharge structure is parallel to the length direction of the steel.

[0045] A label identification machine is located at one end of the feeding rack 4, with its identification window facing the end face of the steel on the feeding rack 4. The label identification machine is electrically connected to the control module of the CNC sawing machine 1. After the label identification machine identifies the label material information on the end of the steel on the feeding rack 4, including information such as the manufacturer, grade, furnace number, and length of the steel, it transmits this information to the control module of the CNC sawing machine 1. The control module of the CNC sawing machine calculates the number of pieces to be cut based on the length of the steel, and then performs cutting according to a preset cutting program after selecting the cutting length and cutting process based on the steel information. When the feeding mechanism 2 feeds the steel, the label identification machine identifies the material to be cut and cooperates with the preset cutting program of the CNC sawing machine 1 to achieve automatic feeding, identification, and cutting processes, saving labor costs and ensuring high dimensional consistency of the cut materials, thus improving cutting efficiency.

[0046] The system includes multiple CNC sawing machines 1, feeding mechanisms 2, discharging mechanisms 6, and marking machines, with each of these components corresponding to the others. A marking machine 7 and a gripping robot 8 are positioned between every two discharging mechanisms 6, and these marking machines 7 and gripping robots 8 are distributed sequentially along the feeding direction of the feeding frame 4. The marking machine 7 can affix traceability tags to the ends of the cut steel, facilitating material traceability and tracking.

[0047] In this application, two CNC sawing machines 1 correspond to a first gripping robot 8 and a marking machine 7. The gripping robot 8 clamps the material from the discharge mechanism 6 and transfers it to the marking machine 7. After the marking machine 7 completes the marking of the cut steel to meet standards, the gripping robot 8 transfers the marked steel from the marking machine 7 to a material placement pallet 9 for stacking. Finally, an AGV (Automated Guided Vehicle) can complete the transfer of the pallet 9 into the warehouse. The gripping robot 8 consists of a robotic arm and a gripper. The gripper can be an electromagnet or a mechanical chuck. For round steel, the gripping robot 8 uses an electromagnet to accommodate round steel of different diameters. For flat steel, the gripping robot 8 uses a mechanical chuck to accommodate flat steel of different widths.

[0048] In one embodiment, to ensure that the cut material can stop at a uniform position for accurate gripping by the gripping robot 8, an inclined guide plate 61 can be set on the discharge mechanism 6 to guide the cut steel to a smaller area. For the discharge mechanism 6 for cutting round steel, the conveying roller at the rear end of the guide plate 61 can be set to be high at one end and low at the other, so that the round steel rolls to one side of the conveying roller, thereby placing the cut round steel in a fixed uniform position. For the cut flat steel, a pushing cylinder can be set at the rear end of the guide plate 61, with a pushing plate at the front end of the pushing cylinder to push the flat steel to one side of the conveying roller and straighten the cut flat steel.

[0049] like Figure 2 and Figure 4 As shown, the material placement rack 3 includes several first support frames 31 spaced apart along a first direction. The top of each first support frame 31 is provided with a crossbar 32. The feeding rack 4 includes a driving component and several second support frames 41 spaced apart along the first direction. The top of each second support frame 41 is provided with a transmission roller 42. The material placement rack 3 and the feeding rack 4 are spaced apart along a direction perpendicular to the first direction. The end of the transmission roller 42 away from the material placement rack 3 is connected to the output end of the driving component through a transmission structure. The driving component drives the transmission roller 42 to rotate through the transmission structure. The crossbar 32 gradually slopes downward from the end away from the feeding rack 4 to the end closer to the feeding rack 4. The end of the crossbar 32 close to the feeding rack 4 is provided with a stop block 33.

[0050] The transfer assembly 5 includes a lifting structure 51 and a lateral movement structure. The output end of the lifting structure 51 is equipped with a receiving plate 52 for receiving steel. The lifting structure 51 drives the receiving plate 52 to rise so that the steel is above the stop block 33 and the transmission roller 42. The lateral movement structure is used to transfer the steel above the stop block 33 and the transmission roller 42 to above the transmission roller 42. This allows the steel on the material rack 3 to slide or roll to one side of the stop block 33 under its own weight. That is, when there is steel on the material rack 3, the steel is always above the initial position of the receiving plate 52, ensuring that the receiving plate 52 can accurately lift the steel.

[0051] like Figure 4 As shown, for the lateral movement structure, in one embodiment, the lateral movement structure includes a translation member, which drives the lifting structure 51 to move between the area between two adjacent first support frames 31 and the area between two adjacent second support frames 41. The lifting structure 51 drives the receiving plate 52 located between the two second support frames 41 to lower so that the steel falls onto the transmission roller 42. The transmission roller 42 then transports the steel to the CNC sawing machine 1. The receiving plate 52 is a U-shaped plate, designed according to different steel diameters or widths to ensure that one steel piece is lifted at a time and to prevent the steel from slipping when the translation member drives the lifting structure 51 to move. In this embodiment, the lifting structure 51 is a cylinder, and the translation member is a combination of a guide rail 53 and a cylinder. Each lifting structure 51 is correspondingly provided with a translation member. The length direction of the guide rail 53 is perpendicular to the first direction. The lifting structure 51 is slidably mounted on the guide rail 53, and the cylinder of the translation member pushes the lifting structure 51 to slide on the guide rail 53. The transverse structure in this embodiment can be used for feeding round steel and flat steel.

[0052] like Figure 5 As shown, in another embodiment of the lateral movement structure, the lateral movement structure includes a plurality of transition rods 54 spaced apart along a first direction. The first end of the transition rod 54 is connected to the first support frame 31, and the second end of the transition rod 54 is connected to the second support frame 41. The top surface of the first end is higher than the top surface of the second end. The top surface of the first end is lower than or flush with the highest point of the stop block 33. The top surface of the second end is higher than or flush with the top surface of the transmission roller 42. The receiving plate 52 is a conical block 55 with the tip of the conical block 55 pointing upward. The top of the conical block 55 is located between the steel closest to the stop block 33 and another adjacent steel. The first side 56 of the conical block 55 located below the steel closest to the stop block 33 is inclined and extends at least to the second end of the transition rod 54 towards the feeding frame 4. The lateral movement structure is used to transfer cylindrical steel.

[0053] The lifting cylinder is fixedly located below the steel closest to the stop block 33. As the lifting structure 51 rises, the conical plate raises the steel while simultaneously moving it towards the feeding rack 4 until the steel height exceeds the stop block 33 and the steel rolls to the edge of the stop block 33. Then, the steel can roll along the transition rod 54 onto the feeding rack 4. In this embodiment, the lifting structure 51 can complete the feeding of cylindrical steel without moving, improving the positioning accuracy of the lifting structure 51. The conical plate is detachably installed on the output end of the lifting structure 51. For round steel of different diameters, only the conical block 55 of different widths needs to be replaced to ensure that the top of the conical block 55 is located between the steel closest to the stop block 33 and another adjacent steel.

[0054] The stop block 33 is a roller 57, which is rotatably mounted on the crossbar 32, and the axis of rotation of the roller 57 is parallel to the first direction. As a stop block 33, the roller 57 can reduce the friction between the steel and the stop block 33 when moving the steel, ensuring that the steel can be lifted and moved smoothly and quickly.

[0055] The highest point of the roller 57 is higher than the vertical center of the steel but lower than the apex of the steel. This ensures that the roller 57 blocks the steel from passing over it under its own weight.

[0056] The first side 56 is provided with a plurality of ball bearings, which are used to contact the outer surface of the steel to reduce the friction between the conical block 55 and the steel.

[0057] The transition rod 54 and the conical block 55 are staggered in the first direction.

[0058] The angle between the transition rod 54 and the horizontal direction ranges from 5-15°. This prevents the steel from reaching the feeding rack 4 too quickly after passing through the transition rod 54. A buffer plate can also be installed on the side of the feeding rack 4 away from the material placement component, positioned above the drive roller 42. The buffer plate can be a rubber plate.

[0059] The cone block 55 has a first side surface 56, and the opposite side surface is a vertical surface. When the cone block 55 is lifted, it does not need to exert a pushing force on the steel behind it, thus reducing the lifting resistance of the cone block 55.

[0060] To prevent the steel from rolling away from the roller 57 when the conical block 55 lifts the steel, the inclination of the first side 56 can be increased, or a baffle 58 can be provided at the top of the conical block 55.

[0061] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
