Description

Technical Field

[0001] This utility model relates to the field of workpiece processing, specifically a steel structure cutting device. Background Technology

[0002] Steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates.

[0003] Currently, steel structures are constructed using I-beams or rectangular tubes. During the processing, workers cut rectangular tubes or I-beams to the corresponding lengths. Cutting machines are mainly divided into two types: blade cutting machines and laser cutting machines. Blade cutting machines rely on a motor to drive the blade to rotate at high speed to cut the workpiece.

[0004] However, during cutting, the workpiece is prone to wobbling and shifting, which affects the cutting accuracy and flatness. Therefore, a steel structure cutting device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a steel structure cutting device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A steel structure cutting device of this utility model includes a frame and a cutting machine. A base is fixedly connected to the middle of the frame. A moving component that enables the cutting machine to move is installed on the base. Multiple conveying rollers are rotatably connected to the frame. A first motor is fixedly connected to the bottom of the base. A cam seat is fixedly connected to the output end of the first motor. Both ends of the cam seat are rotatably connected to connecting rods. The ends of the connecting rods are rotatably connected to connecting frames. The connecting frames and the base are slidably connected. Both ends of the connecting frames are fixedly connected to fixed seats. By relying on the above arrangement, the fixed seats are driven to move closer to each other towards the rectangular tube clamp, thereby improving the cutting accuracy and reducing the vibration that occurs during the cutting of the rectangular tube.

[0007] Preferably, the moving assembly includes a lead screw, a second motor, and a support. The support is fixedly connected to the cutting machine, the lead screw is rotatably connected to the machine base, the second motor is fixedly connected to the top of the machine base, the output end of the second motor is fixedly connected to the lead screw, and the lead screw passes through the support and is connected to it via a ball screw nut pair.

[0008] Preferably, a plurality of guide posts are fixedly connected to the side of the base, and a sliding sleeve is fixedly connected to the connecting frame at a position corresponding to the guide posts. The guide posts pass through the sliding sleeve and are slidably connected to it. With the above arrangement, the moving stability of the connecting frame and the fixed base can be improved, thereby facilitating the improvement of the stability of the rectangular tube clamping.

[0009] Preferably, the fixed base has a groove inside, and a pulley is installed in the groove. The pulleys on both sides are used to guide the rectangular tube and improve the stability of the rectangular tube's movement.

[0010] Preferably, the top and bottom of the groove are provided with sliding grooves, both ends of the pulley are rotatably connected to sliders, the sliders are located in the sliding grooves, the sliders and the sliding grooves are slidably connected, and the side of the sliding groove block is fixedly connected to a spring, the end of the spring is fixedly connected to the side wall of the sliding groove.

[0011] Preferably, a friction pad is fixed to the side of the fixing seat. The friction pad is made of hard rubber. By setting the friction pad, the friction between the rectangular tubes can be increased, thereby improving the fixing effect.

[0012] The advantages of this utility model are:

[0013] 1. This utility model, by setting up a first motor, a cam seat, a connecting rod, a connecting frame, and a fixed seat, allows the first motor to drive the cam seat to rotate before cutting. The rotation of the cam seat will pull the connecting frame to move through the connecting rod. The two connecting frames will move closer to each other, which in turn will drive the fixed seat to move closer to each other and clamp the square and rectangular tube. This can improve the cutting accuracy and reduce the shaking that occurs during the cutting of the square and rectangular tube.

[0014] 2. By setting guide posts and sliding sleeves, this utility model improves the stability of the moving frame and the fixed seat during use, thereby facilitating the stability of clamping the rectangular tube. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-5 As shown, a steel structure cutting device includes a frame 11 and a cutting machine 14. A base 12 is fixedly connected to the middle of the frame 11. A moving assembly capable of moving the cutting machine 14 is mounted on the base 12. Multiple conveying rollers 13 are rotatably connected to the frame 11. A first motor 15 is fixedly connected to the bottom of the base 12. A cam seat 16 is fixedly connected to the output end of the first motor 15. Connecting rods 17 are rotatably connected to both ends of the cam seat 16. The ends of the connecting rods 17 are rotatably connected to... The connecting frame 18 is slidably connected to the machine base 12, and fixed seats 19 are fixedly connected to both ends of the connecting frame 18; the moving component includes a lead screw 22, a second motor 21 and a support 23, the support 23 is fixedly connected to the cutting machine 14, the lead screw 22 is rotatably connected to the machine base 12, the second motor 21 is fixedly connected to the top of the machine base 12, the output end of the second motor 21 is fixedly connected to the lead screw 22, and the lead screw 22 passes through the support 23 and is connected to it through a ball screw nut pair.

[0025] In use, the rectangular tube is placed on the frame 11, which is driven by the conveyor roller 13 driven by the motor to move the rectangular tube. After the rectangular tube moves to the designated position, the cutting machine 14 is started. Then, the second motor 21 drives the lead screw 22 to rotate, thereby moving the support 23. In this way, the support 23 and the cutting machine 14 move to cut the rectangular tube.

[0026] Before cutting, the first motor 15 drives the cam seat 16 to rotate. The rotation of the cam seat 16 will pull the connecting frame 18 to move through the connecting rod 17. The two connecting frames 18 move closer to each other, which in turn drives the fixed seat 19 to move closer to each other and clamp the square and rectangular tube. This can improve the cutting accuracy and reduce the shaking during the cutting of the square and rectangular tube. The first motor 15 is preferably a servo geared motor.

[0027] Furthermore, such as Figures 1-2 As shown, a plurality of guide posts 31 are fixedly connected to the side of the base 12, and a sliding sleeve 32 is fixedly connected to the connecting frame 18 at a position corresponding to the guide post 31. The guide post 31 passes through the sliding sleeve 32 and is slidably connected to it. In this embodiment, the sliding sleeve 32 on the moving frame slides on the guide post 31, which can improve the stability of the moving of the connecting frame 18 and the fixed base 19, thereby facilitating the improvement of the stability of the rectangular tube clamping.

[0028] Furthermore, such as Figure 5 As shown, the fixed base 19 has a groove 41 inside, and a pulley 42 is installed in the groove 41. During use, the square and rectangular tube moves by relying on the pulleys 42 on both sides, which guide the square and rectangular tube and improve the stability of the movement of the square and rectangular tube.

[0029] Furthermore, such as Figure 5 As shown, the top and bottom of the groove 41 are provided with sliding grooves 51. Both ends of the pulley 42 are rotatably connected to sliders 52. The sliders 52 are located in the sliding grooves 51 and are slidably connected to the sliding grooves 51. A spring 53 is fixedly connected to the side of the sliding groove 51, and the end of the spring 53 is fixedly connected to the side wall of the sliding groove 51. A friction pad 6 is fixedly connected to the side of the fixing seat 19. The friction pad 6 is made of hard rubber. In this embodiment, the slider 52 and the sliding groove 51 on the fixing seat 19 are slidably connected, so that the pulley 42 can slide and extend. The spring 53 is used to support the slider 52 and the pulley 42. When the rectangular tube is fixed, the pulley 42 is squeezed into the groove 41, so that the fixing seat 19 and the rectangular tube are fitted and fixed. The spring 53 is a hard spring 53. By setting the friction pad 6, the friction between the rectangular tubes can be increased, and the fixing effect can be improved.

[0030] Furthermore, such as Figures 2-3 As shown, the base 12 is slidably connected to the support 23 via the slide rail 7.

[0031] Working principle: During use, the rectangular tube is placed on the frame 11, and is moved by the motor-driven conveyor roller 13. After the rectangular tube moves to the designated position, the cutting machine 14 is started. Then, the second motor 21 drives the lead screw 22 to rotate, which in turn moves the support 23. This allows the support 23 and the cutting machine 14 to move and cut the rectangular tube. Before cutting, the first motor 15 drives the cam seat 16 to rotate. The rotation of the cam seat 16 pulls the connecting frame 18 to move through the connecting rod 17. The two connecting frames 18 move closer to each other, which in turn moves the fixed seat 19 closer to each other to clamp the rectangular tube. This improves the cutting accuracy and reduces vibration during the cutting process. The first motor 15 is preferably a servo geared motor. The sliding sleeve 32 on the upper part slides on the guide post 31, which can improve the stability of the movement of the connecting frame 18 and the fixed seat 19, thereby facilitating the stability of clamping the rectangular tube. During use, the rectangular tube moves by relying on the pulleys 42 on both sides, which guide the rectangular tube and improve the stability of its movement. The slider 52 and the sliding groove 51 on the fixed seat 19 are slidably connected, so that the pulley 42 can slide telescopically. The spring 53 supports the slider 52 and the pulley 42. When fixing the rectangular tube, the pulley 42 is squeezed into the groove 41, so that the fixed seat 19 and the rectangular tube fit together and are fixed. The spring 53 is a hard spring 53. By setting the friction pad 6, the friction between the rectangular tubes can be increased, thereby improving the fixing effect.
