Description

Technical Field

[0001] The invention belongs to the technical field of steel structure bridge processing, and in particular relates to a plate cutting machine for steel structure bridge processing. Background Art

[0002] Steel bridges, constructed primarily with steel, hold a crucial position in modern bridge construction due to their inherent strengths. Steel's high strength allows it to easily bear heavy loads, allowing bridges to span longer distances and accommodate large spans. Bridges spanning rivers and bays often utilize steel structures. Its excellent toughness allows it to resist deformation and damage in diverse environments, resulting in high safety. Furthermore, steel bridges are fast to construct, shortening construction schedules and reducing costs. Steel plates are a key component of steel bridges. They are processed into various shapes and components, then welded or bolted together to form the bridge structure. High-quality steel plates guarantee the overall performance of a bridge, and their quality directly impacts its durability and stability. In harsh environments, such as areas prone to strong winds and earthquakes, bridges built with high-quality steel plates can better withstand disasters and ensure traffic safety. During the processing of steel plates for steel structure bridges, plate cutting machines are often used to cut the steel plates. In existing technologies, there are various ways to cut steel plates, such as flame cutting, plasma cutting, laser cutting, water jet cutting and circular saw cutting. Although flame cutting can cut thick plates, the heat-affected zone is large during the processing and the cost of consumables is high. Although plasma cutting has a faster cutting speed, the cutting surface has a larger slope and generates greater noise and dust. Laser cutting has the problems of expensive equipment, high loss and high maintenance cost. Water jet cutting has the problems of expensive equipment, slow cutting speed and large footprint, so many manufacturers still use circular saws for cutting.

[0003] The existing circular saw type steel plate cutting machine is mainly composed of a bed, a saw frame, a transmission mechanism, a guide device and other structures. Although this type of steel plate cutting machine can cut steel plates, it does not have a steel plate conveying and steel plate pressing mechanism. Instead, it cuts the plate by moving the saw blade or manually pushing the steel plate to cut the steel plate. In addition, the existing steel plate cutting machine does not have a stress relief mechanism. During the rolling and heat treatment process, the steel plate often produces internal stress. If the internal stress is not handled, the steel plate is prone to cracking, warping and other problems during cutting. For example, the utility model patent with announcement number CN205085468U, the device moves linearly to The device drives the saw blade to move horizontally, and the gearbox drives the saw blade to rotate and cut the workpiece. In actual use, the equipment does not have a steel plate conveying mechanism, and the movement range of its saw blade is limited. Therefore, this equipment can only cut steel plates that do not exceed the length of the equipment. The equipment also does not have a steel plate clamping mechanism. The staff must additionally install a clamping mechanism to ensure the stability of the steel plate, resulting in a waste of manpower. In addition, the existing clamping mechanism can often only fix the edge of the steel plate and cannot directly press the area near the cutting point. During cutting, since the steel plate fixing point is far away from the cutting point, the steel plate at the cutting point will still vibrate slightly, which has an adverse effect on the cutting quality of the steel plate.

[0004] Therefore, it is urgent to provide a plate cutting machine for steel structure bridge processing to solve the above problems. Summary of the Invention

The rotating rod and the rubber layer together constitute a multi-section rubber roller structure, and there are multiple multi-section rubber rollers. The first motor is a servo motor. The first motor can drive the driving screw to rotate forward or reverse. The sliding frame is threadedly connected to the driving screw. When the first motor is started, the sliding frame can translate along the gantry, thereby changing the position of the cutting mechanism.

[0009] The present invention is further configured as follows: the cutting mechanism includes a first hydraulic cylinder fixed on a sliding frame, a lifting frame is fixed to the telescopic end of the first hydraulic cylinder, a first shell and a second shell are welded to the bottom of the lifting frame, a second hydraulic cylinder is also fixed on the lifting frame, a cutting machine body is fixed to the telescopic end of the second hydraulic cylinder, a limiting rod is fixed on the cutting machine body, and a connecting hole is also provided on the cutting machine body.

[0010] Through the above technical solution, the first hydraulic cylinder can drive the lifting frame to rise and fall, and multiple mounting holes are provided on the first shell and the second shell. The second hydraulic cylinder can drive the cutting machine body to rise and fall, thereby changing the relative height of the cutting machine body and the first shell and the second shell. The limiting rod is slidably connected to the lifting frame, which can ensure the stability of the cutting machine body during lifting and falling.

[0011] The present invention is further configured as follows: the driving mechanism includes a second motor fixed on the second shell, a reducer is fixed to the output end of the second motor, a rotating shaft is fixed to the output end of the reducer, a first gear is fixed to the end of the rotating shaft, a first sprocket is coaxially fixed to one end of the first gear, a second sprocket is coaxially fixed to the other end of the first gear, and a second gear is also fixed on the rotating shaft.

[0012] Through the above technical solution, the reducer can reduce the speed of the second motor and increase its torque. The second motor can drive the shaft to rotate through the reducer. The second gear is provided with the same sprocket structure as the first gear.

[0013] The present invention is further configured as follows: the track mechanism includes a third gear meshed with the first gear, a fourth gear is meshed with the other side of the third gear, a fifth gear is meshed with the side of the fourth gear away from the third gear, and a sixth gear is meshed with the other side of the fifth gear, an inner chain plate is meshed with the first sprocket, an outer chain plate is movably connected to the outside of the inner chain plate, screw holes are provided on the outer chain plate, a second chain is meshed with the second sprocket, a connecting steel plate is bolted to the outer chain plate, a rubber sheet is fixed on the connecting steel plate, and the track mechanism also includes a second crawler meshed with the second gear.

[0014] Through the above technical solution, the fourth gear and the sixth gear are both provided with a sprocket structure identical to the first gear, and the third gear and the fifth gear enable the fourth gear and the sixth gear to rotate synchronously with the first gear. The inner chain plate and the outer chain plate are connected together to form a transmission connecting bar, and the second chain has the same structure as the transmission chain. The two ends of the connecting steel plate are fixed to the outer chain plates of the two chains by screws and screw holes respectively. The above-mentioned sprockets are respectively engaged with the transmission chain and the second chain, thereby forming a rubber track structure. When the first gear rotates, the rubber track will also rotate accordingly. The second track has the same structure as the rubber track. The second track is driven by the second gear, and the gears of the two rubber tracks are rotatably connected to the mounting holes on the first shell and the second shell respectively. The two track structures Located on both sides of the cutting mechanism, when the second motor is started, the two crawler structures will rotate synchronously, and the staff will insert the steel plate between the crawler and the rubber layer, and the two crawlers can transport the steel plate. When the steel plate passes through the cutting mechanism, the cutting mechanism can cut the steel plate, thereby automatically pushing the steel plate. At the same time, the two crawlers can also press on both sides of the cut part of the steel plate, thereby avoiding vibration or shaking of the steel plate and improving the neatness of the incision. The fourth gear can effectively ensure that the middle part of the rubber crawler is not concave, and ensure that the middle part of the rubber crawler can also fully contact the steel plate, thereby increasing the friction of the rubber crawler and evenly distributing the pressure of the steel plate on the crawler. When individual connecting steel sheets and rubber sheets are damaged, the staff only needs to remove two screws to maintain it.

[0015] The present invention is further configured as follows: the first deburring mechanism includes a third motor fixed on the lifting frame, the output end of the third motor is fixed with an output shaft, the bottom of the output shaft is fixed with a connecting disk, and the bottom of the connecting disk is fixed with steel wire bristles.

[0016] Through the above technical solution, the wire brush bristles and the connecting disk form a burr removal brush, which is aligned with the cutting machine body. When the third motor is started, it can drive the connecting disk and the wire brush bristles to rotate through the output shaft, thereby cleaning the burrs generated on the top of the steel plate during the cutting process.

[0017] The present invention is further configured as follows: the second deburring mechanism includes a fourth motor fixed on the frame, a wire roller is fixed to the output end of the fourth motor, a first pulley is fixed to the end of the wire roller, and a synchronous belt is provided on the outside of the first pulley.

[0018] Through the above technical solution, the fourth motor can drive the wire roller to rotate at high speed, and the wire roller contacts the bottom of the steel plate. When the wire roller rotates at high speed, it can clean the burrs generated on the bottom of the steel plate during the cutting process.

[0019] The present invention is further configured as follows: the reciprocating mechanism includes a second pulley sleeved on the end of the synchronous belt, a reciprocating screw is coaxially fixed on the second pulley, two bearings are fixed on the reciprocating screw, two limiting sleeves are sleeved on the reciprocating screw, an inner convex pattern is integrally fixed on the inner side of the limiting sleeve, and a first pressing plate and a second pressing plate are also fixed on the limiting sleeve.

[0020] Through the above technical solution, when the fourth motor is started, the first pulley drives the second pulley to rotate through the synchronous belt, thereby causing the reciprocating screw to rotate. The cross-section of the limit sleeve is C-shaped, and the inner convex groove on the inner side of the limit sleeve matches the reciprocating thread on the reciprocating screw, and there is a triangular notch at one end of the limit sleeve. When the staff presses the first pressing plate and the second pressing plate, the inner diameter of the limit sleeve will become larger. At this time, the staff can adjust the position of the limit sleeve. When the limit sleeve is tightened, its inner convex groove and the reciprocating thread on the reciprocating screw are locked with each other, and under the cover of the triangular notch at the end of the limit sleeve, the reciprocating thread at this place changes from X-type to V-type with the opening facing one side, and its shape is the same as the end of the reciprocating thread, thereby being able to change the length of the effective reciprocating thread.

[0021] The present invention is further configured as follows: the stress relief mechanism includes a slider movably arranged on the outside of the reciprocating screw, a sliding hole is provided on the slider, a rod penetration hole is also provided on the slider, a crescent pin is rotatably connected to the inner side of the rod penetration hole, a mounting bracket is also fixed on the slider, a sliding groove is provided on the mounting bracket, a third hydraulic cylinder is fixed on the top of the mounting bracket, a lifting plate is fixed on the telescopic end of the third hydraulic cylinder, a telescopic rod is fixed on the bottom of the lifting plate, a spring is provided on the outside of the telescopic rod, a stress relief machine is fixed on the bottom end of the telescopic rod, and a working end is fixed on the bottom end of the stress relief machine.

[0022] Through the above technical solution, the slider is slidably connected to the slider through the sliding hole, the reciprocating screw passes through the rod hole, and the crescent pin is stuck in the reciprocating thread on the reciprocating screw. When the reciprocating screw rotates, the crescent pin will move back and forth along the reciprocating screw, thereby driving the slider to move back and forth along the reciprocating screw. The reciprocating movement range of the slider can be changed through two limit sleeves, thereby adjusting the active range of the stress relief mechanism to match the width of the steel plate. The lifting plate is slidably connected to the slide groove, and the stress relief machine is an ultrasonic stress relief machine. When the third hydraulic cylinder extends, the lifting plate drives the stress relief machine to press down, and conversely, the height of the stress relief machine increases, thereby making the stress relief machine The structure can be applied to steel plates of different thicknesses. The telescopic rod and spring form a stable elastic connection between the stress relief machine and the lifting plate, so that the working end can always be in contact with the surface of the steel plate. When the device cuts the steel plate, the stress relief machine will move left and right along the reciprocating screw within a certain range to relieve the stress of the steel plate. Since the crawler mechanism can drive the steel plate to move during the cutting process, the stress relief machine will relieve the stress along a zigzag line on the steel plate, thereby ensuring that the stress in various parts of the steel plate is fully eliminated, avoiding cracking of the steel plate due to stress during processing, and preventing the processed steel plate from warping due to internal stress.

[0023] The present invention is further configured as follows: the water cooling mechanism includes a water tank fixed on a frame plate, a water pump is fixed on the water tank, the water inlet end of the water pump is sealedly connected to a water suction pipe, the water outlet end of the water pump is sealedly connected to a water hose, the end of the water hose is sealedly connected to a metal rigid pipe, a fixing frame is fixed to the outside of the metal rigid pipe, and a water spray port is opened at the end of the metal rigid pipe.

[0024] Through the above technical solution, the water spray port is sealed and connected to the connecting hole on the cutting machine body, the water suction pipe extends into the bottom of the water tank, and clean water is stored in the water tank. One end of the fixing frame is fixed to the metal hard pipe, and the other end is fixed to the cutting machine body, thereby ensuring the stability of the metal hard pipe. When the device is cutting, the water pump starts and draws out the clean water in the water tank through the water suction pipe, and transports the clean water to the metal hard pipe through the water supply hose, and sprays it into the connecting hole through the water spray port. The connecting hole faces the saw blade of the cutting machine body. The clean water is poured on the saw blade, which can effectively cool the saw blade with water. Under the action of gravity, some water will fall on the cutting part of the steel plate to prevent the saw blade or the steel plate from being overheated.

[0025] The beneficial effects of the present invention are as follows: 1. The present invention adopts the arrangement of the chassis mechanism, the driving mechanism and the crawler mechanism, so that the device can push the steel plate, saving manpower and improving safety. It can also press the two sides of the cutting part to prevent the steel plate from vibrating during cutting, thereby effectively improving the processing quality. 2. The present invention provides a reciprocating mechanism and a stress relief mechanism, so that the device can perform ultrasonic stress relief on various parts of the steel plate, thereby avoiding cracking or deformation of the steel plate when cutting.

[0026] 3. The present invention can deburr the bottom and top of the steel plate cut by setting the first deburring mechanism and the second deburring mechanism, thereby preventing the burrs from cutting the operator and improving the assembly accuracy of the steel plate when it is used.

The inner convex groove 705 on the inner side of the limiting sleeve 704 matches the reciprocating thread on the reciprocating screw rod 702, and there is a triangular notch at one end of the limiting sleeve 704. When the staff presses the first pressing plate 706 and the second pressing plate 707, the inner diameter of the limiting sleeve 704 will become larger. At this time, the staff can adjust the position of the limiting sleeve 704. When the limiting sleeve 704 is tightened, its inner convex groove 705 and the reciprocating thread on the reciprocating screw rod 702 are locked with each other, and under the cover of the triangular notch at the end of the limiting sleeve 704, the reciprocating thread at this place changes from X-type to V-type with the opening facing one side, and its shape is the same as the end of the reciprocating thread, thereby being able to change the length of the effective reciprocating thread.

[0037] like Figure 1 and Figure 13 As shown, the reciprocating mechanism 7 is provided with a stress relief mechanism 8 on the outside of the reciprocating screw 702. The stress relief mechanism 8 includes a slider 801 movably provided on the outside of the reciprocating screw 702. The slider 801 is provided with a sliding hole 802. The slider 801 is also provided with a rod hole 803. The inner side of the rod hole 803 is rotatably connected with a crescent pin 804. The slider 801 is also fixed with a mounting bracket 805. The mounting bracket 805 is provided with a slide groove 806. The top of the mounting bracket 805 is fixed with a third hydraulic cylinder 807. The telescopic end of the third hydraulic cylinder 807 is fixed with a lifting plate 808. The bottom of the lifting plate 808 is fixed with a third hydraulic cylinder 807. A telescopic rod 809 is fixed to the top, and a spring 810 is provided on the outer sleeve of the telescopic rod 809. A stress relief machine 811 is fixed to the bottom end of the telescopic rod 809, and a working end 812 is fixed to the bottom end of the stress relief machine 811. The slider 801 is slidably connected to the slider 1010 through the sliding hole 802. The reciprocating screw rod 702 passes through the rod hole 803, and the crescent pin 804 is stuck in the reciprocating thread on the reciprocating screw rod 702. When the reciprocating screw rod 702 rotates, the crescent pin 804 will move back and forth along the reciprocating screw rod 702, thereby driving the slider 801 to move back and forth along the reciprocating screw rod 702. The two limiting sleeves 704 can change the reciprocating range of the slider 801, thereby adjusting the active range of the stress relief mechanism 8 to match the width of the steel plate. The lifting plate 808 is slidably connected to the slide 806. The stress relief machine 811 is an ultrasonic stress relief machine 811. When the third hydraulic cylinder 807 is extended, the lifting plate 808 drives the stress relief machine 811 to press down, and vice versa, the height of the stress relief machine 811 is increased, so that the stress relief mechanism 8 can be applied to steel plates of different thicknesses. The telescopic rod 809 and the spring 810 make the stress relief machine 811 and the lifting plate 808 A stable elastic connection is formed between them, so that the working end 812 can always be in contact with the surface of the steel plate. When the device cuts the steel plate, the stress relief machine 811 will move left and right along the reciprocating screw 702 within a certain range, thereby relieving the stress of the steel plate. Since the crawler mechanism 4 can drive the steel plate to move during the cutting process, the stress relief machine 811 will relieve the stress along a zigzag line on the steel plate, thereby ensuring that the stress in various parts of the steel plate is fully eliminated, avoiding the steel plate from cracking due to stress during the processing, and preventing the processed steel plate from warping due to internal stress.

[0038] like Figure 1 and Figure 14As shown, a water cooling mechanism 9 is fixed on the chassis mechanism 1, and the water cooling mechanism 9 includes a water tank 901 fixed on the frame plate 103, a water pump 902 is fixed on the water tank 901, the water inlet end of the water pump 902 is sealedly connected to a water pumping pipe 903, the water outlet end of the water pump 902 is sealedly connected to a water delivery hose 904, the end of the water delivery hose 904 is sealedly connected to a metal hard pipe 905, a fixing frame 906 is fixed to the outside of the metal hard pipe 905, a water spray port 907 is opened at the end of the metal hard pipe 905, the water spray port 907 is sealedly connected to the connection hole 208 on the cutting machine body 206, the water pumping pipe 903 extends into the bottom of the water tank 901, and the water tank 901 is provided with a water supply pipe 903. Clean water is stored, one end of the fixing frame 906 is fixed to the metal hard pipe 905, and the other end is fixed to the cutting machine body 206, so as to ensure the stability of the metal hard pipe 905. When the device is cutting, the water pump 902 is started and the clean water in the water tank 901 is pumped out through the water pumping pipe 903, and the clean water is transported to the metal hard pipe 905 through the water supply hose 904, and sprayed into the connecting hole 208 through the water nozzle 907. The connecting hole 208 faces the saw blade of the cutting machine body 206. The clean water is poured on the saw blade, which can effectively cool the saw blade. Under the action of gravity, some water will fall on the cutting part of the steel plate to prevent the saw blade or the steel plate from being overheated.

[0039] When the present invention is in use, the staff first turns on the device, adjusts the cutting mechanism 2 to the specified position and height, and then inserts the steel plate between the track mechanism 4 and the rubber roller. At this time, the track mechanism 4 will drive the steel plate to move toward the cutting machine body 206, so that the cutting machine body 206 cuts the steel plate. At the same time, the reciprocating mechanism 7 will drive the stress relief mechanism 8 to relieve the stress of the steel plate along a zigzag route on the steel plate. The first deburring mechanism 5 and the second deburring mechanism 6 can remove burrs at the bottom and top of the steel plate incision.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
