Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel member cutting, and particularly relates to a cutting mechanism of a full-automatic steel member welding device. BACKGROUND

[0002] In the modern steel member manufacturing industry, welding is a key process for building complete steel members, and cutting, as an important preparation process before welding, has a decisive influence on the quality and production cycle of the final product. With the development of the demand for steel members in the construction, bridge, and mechanical manufacturing industries towards high precision, large scale, and diversification, full-automatic steel member welding devices have emerged to meet the efficient and stable production needs.

[0003] In the prior art, there are various cutting methods for steel members, and laser cutting and cutting knife cutting are relatively common. Laser cutting can achieve relatively fine and fast cutting operation by virtue of its high-energy-density light beam. However, when cutting tubular steel members, the high temperature generated in the laser cutting process can cause part of the steel to melt. These melts are extremely easy to adhere to the inner wall of the tubular steel member to form slag under the action of gravity and airflow. These slag not only are difficult to clean, but also affect the pipe butt joint precision during subsequent welding, reduce the weld quality, and even may cause defects such as pores and inclusions at the welding position, which seriously affect the cutting effect and the welding quality of the entire steel member.

[0004] During the cutting process, the cutting knife directly contacts and rubs against the surface of the steel member, which generates a large cutting force. This not only easily causes the cutting knife to wear out and shorten the service life of the tool, increases the production cost, but also causes a large deformation at the cut end of the steel member. Especially for some thin-walled or high-precision steel members, the deformation may exceed the allowable range, affecting the dimensional accuracy and surface quality of the steel member. SUMMARY

[0011] Preferably, the transmission component includes a second motor, two gears and a transmission rod. The two gears are fixedly mounted on the surface of the transmission rod.

[0017] The application has at least the following advantages:

[0018] 1. Adopting the advanced mode of laser cutting and cutting knife cutting cooperation. In the initial stage, laser cutting technology is used to keep the laser cutting position constant and drive the tubular steel to rotate at a constant speed. In this process, the laser precisely acts on the surface of the tubular steel, gradually cutting off a circular part. When the cutting process approaches the end, the cutting knife is switched to cutting at the critical node just before completion but not completely cut off. The cutting knife also cuts around the tubular steel. This unique combination of processes can effectively avoid the problem of slag entering the tubular workpiece when traditional single laser cutting is used. Because the cutting knife intervenes in time when the laser cutting is almost complete, it avoids the excessive slag produced by the continuous action of the laser entering the pipe wall, affecting the subsequent welding operation, and greatly reduces the risk of slag pollution and affecting subsequent processing of the workpiece.

[0019] 2. Adopting the rotating cutting mode of workpiece rotation and fixed cutting point, compared with the traditional one-time cutting mode, it can significantly improve the flatness and neatness of the cutting surface. In the rotating process, the cutting point always acts on the workpiece in a stable state, ensuring the consistency and continuity of the cutting path, effectively reducing the cutting deviation caused by the movement of the cutting point or the instability of the workpiece, making the cut edge more neat and smooth, greatly improving the cutting quality of the tubular steel, and providing a better foundation for subsequent processing procedures.

[0020] 3. For plate-shaped workpieces, the processing method is also ingenious. The plate-shaped workpiece is directly placed on the support plate with evenly arranged rollers, the bottom of the plate-shaped workpiece is in good contact with the rollers, and the top is in contact with the triangular chuck with high-friction rubber ring on the circumferential surface. When the triangular chuck rotates, it can smoothly drive the plate-shaped workpiece to move, thereby perfectly cooperating with the cutting device for cutting. This design not only ingeniously utilizes the driving function of the triangular chuck, but also reduces the resistance of the plate-shaped workpiece when moving with the help of the rollers, ensuring smooth cutting process. At the same time, this fixed and driven mode expands the application range of the cutting process. Whether it is a tubular workpiece or a plate-shaped workpiece, it can realize efficient and accurate cutting under the mode of laser cutting and cutting knife cutting cooperation, and laser cutting and cutting knife cutting can be used arbitrarily.

[0021] 4. The triangular chuck and auxiliary components can realize the movement of the plate-shaped workpiece in one direction, and the entire mounting seat can move in another direction perpendicular to it, providing diversity and convenience for the cutting of plate-shaped workpieces.

[0022] 5. After the tubular workpiece is cut, the two workpiece segments can be moved away from each other, and the entire sliding arm can be moved down until the two grinding discs are between the two workpiece segments. Then, the two workpiece segments are brought closer together again, so that the two cut surfaces come into contact with the two grinding discs, which facilitates the grinding operation. During the grinding process, the grinding discs are driven by a fourth motor, and the workpiece rotates on the triangular chuck using a transmission component, so that the entire end can be ground evenly, improving the grinding effect.

[0040] Referring to Figures 1-10 A cutting mechanism of a full-automatic steel member welding equipment, including a base 1, a vertical rod 2 is fixedly installed on the surface of the base 1, a sliding arm 4 is slidingly connected to the surface of the vertical rod 2, the vertical rod 2 is fixedly installed on the surface of the base 1 and forms a stable structural connection with the base 1. The sliding of the sliding arm 4 on the surface of the vertical rod 2 is realized by a specific sliding connection structure therebetween. The power is derived from an external first electric telescopic rod 3 which is installed at the top of the vertical rod 2. When the first electric telescopic rod 3 is started to extend or contract, the output end pushes or pulls the sliding arm 4 to move axially up and down along the vertical slot formed on the side wall of the vertical rod 2. A cutting system 12 is arranged on the surface of the sliding arm 4, the cutting system 12 includes a rotating disc 121, a cutting knife 125 and a laser cutting gun 124, the rotating disc 121 is rotatably connected to the surface of the sliding arm 4, the cutting knife 125 and the laser cutting gun 124 are respectively installed at two ends of the circumferential surface of the rotating disc 121, and the rotating disc 121 is rotatably connected to the surface of the sliding arm 4. When cutting the tubular steel member, the rotating disc 121 is first driven to switch the laser cutting gun 124 to the working position. The laser cutting gun 124 emits a high-energy-density laser beam, and the tubular steel member can be automatically rotated to cut along the circumference of the tubular steel member, so that the surface material of the steel member is instantaneously melted or vaporized. When the tubular steel member is about to be completely cut, only a small part is left connected, the rotating disc 121 is driven again to switch the cutting knife 125 to the working position. The cutting knife 125 performs the final cutting on the part which has been cut by the laser but has not been completely separated by high-speed rotation; a mounting seat 5 is arranged on the surface of the base 1, the surface of the mounting seat 5 is provided with a mounting assembly 8, the mounting assembly 8 includes two mounting plates 83 which are slidingly connected to the surface of the mounting seat 5, the surface of the mounting seat 5 is provided with a second driving mechanism 11 for driving the two mounting plates 83 to move relative to each other, the second driving mechanism 11 can drive the two mounting plates 83 to move relative to each other, so that the cut steel members can be moved away from each other by a certain distance, and then the cut ends of the two steel members can be in contact with the polishing disc 123 for polishing work. The side of each of the two mounting plates 83 which moves towards each other is provided with a triangular chuck 81, and the tubular steel member can be fixed by the triangular chuck 81. The surface of the mounting plate 83 is provided with a transmission member 9 for driving the triangular chuck 81 to rotate, so as to slowly rotate the fixed tubular steel member, and then facilitate the uniform cutting of the steel member at the cutting position at the bottom of the cutting system 12; an auxiliary assembly 10 is arranged on the surface of each of the two mounting plates 83 for cooperation with the two triangular chucks 81 to fix and move the plate-shaped steel member. The auxiliary assembly can enable the equipment to fix and cut the plate-shaped steel member, and improve the functionality.

[0041] Furthermore, the cutting system 12 also includes a fourth motor 122 and a mounting shaft 126. One end of the sliding arm 4 has an "I"-shaped structure and a mounting groove is provided on its surface. The mounting shaft 126 rotates through the mounting groove. The turntable 121 is rotatably connected to the surface of the mounting shaft 126. Grinding discs 123 are fixedly installed on both sides of the turntable 121 on the surface of the mounting shaft 126. The fourth motor 122 is fixedly installed on the side wall of the sliding arm 4. The output shaft port of the fourth motor 122 is fixedly connected to the mounting shaft 126. The surface of the sliding arm 4 is provided with a first drive mechanism 7 that restricts the rotation of the turntable 121. When it is necessary to perform grinding operation after cutting the tubular steel component, firstly, the two steel components are moved away from each other, and the entire sliding arm 4 is moved down so that the grinding discs 123 are located between the two steel components. Then, the two steel components are brought closer to each other and contact the two grinding discs 123. The fourth motor 122 is started, and the output shaft of the fourth motor 122 rotates, driving the mounting shaft 126 to rotate in the mounting groove. When the mounting shaft 126 rotates, the grinding disc 123 mounted on its surface also rotates, and the grinding disc 123 can grind the cutting area. The first drive mechanism 7 is used to precisely control the rotation of the turntable 121. When it is necessary to switch the cutting mode, the power source in the first drive mechanism 7 is activated, transmitting power to the turntable 121, causing the turntable 121 to rotate around the axis of the mounting shaft 126, switching the cutting blade 125 and the laser cutting gun 124 to the required working position.

[0042] Furthermore, the first drive mechanism 7 includes a first motor 73 and a transmission shaft 71. The first motor 73 is fixedly mounted on the surface of the sliding arm 4, and the transmission shaft 71 is rotatably connected to the surface of the sliding arm 4. The output shaft port of the first motor 73 is fixedly connected to one end of the transmission shaft 71. A worm gear 72 is fixedly mounted on the surface of the transmission shaft 71, and a worm wheel 74 is fixedly sleeved on the surface of the turntable 121. The worm gear 72 and the worm wheel 74 mesh. The first drive mechanism 7 is used to precisely control the rotation of the turntable 121. When it is necessary to switch the cutting mode, the first motor 73 is started. The first motor 73 is fixed on the surface of the sliding arm 4, and its output shaft drives the transmission shaft 71, which is fixedly connected to it, to rotate. Since the transmission shaft 71 is rotatably connected to the surface of the sliding arm 4, it can rotate smoothly. The worm 72, fixedly mounted on the surface of the drive shaft 71, rotates accordingly. Since the worm 72 meshes with the worm wheel 74 fixedly sleeved on the surface of the turntable 121, the worm wheel 74 rotates along with the worm 72, thereby driving the turntable 121 to rotate around its axis, thus achieving the position switching between the cutting blade 125 and the laser cutting gun 124. Simultaneously, the transmission mechanism between the worm wheel 74 and the worm 72 has a self-locking effect, thus ensuring that the rotation is stably maintained at a fixed angle.

[0043] Furthermore, movable plates 127 are slidably connected to the bottom of both ends of the "I"-shaped structure of the sliding arm 4. Each of the two movable plates 127 has a receiving groove on the side that is close to each other, and the bottom of the receiving groove is provided with a groove. The inner wall of the receiving groove is covered with felt 128. When the cutting blade 125 cuts the workpiece, some debris will jump out with the cutting blade 125. The movable plates 127 can block it. The relatively soft felt 128 can prevent the debris from bouncing after it splashes on it, and thus make it fall into the groove. The movable plates 127 can be inserted into the sliding arm 4. Therefore, even if the sliding arm 4 slides downward, it will not be affected by the movable plates 127.

[0044] Furthermore, the transmission component 9 includes a second motor 93, two gears 94, and a transmission rod. The two gears 94 are fixedly mounted on the surface of the transmission rod. The two mounting plates 83 are rotatably connected to gear rings 82 on their adjacent sides. The triangular chuck 81 is fixedly connected to the gear rings 82. The two gears 94 mesh with the two gear rings 82 respectively. Starting the second motor 93 can rotate the transmission rod, which drives the two gears 94 to rotate. The two gears 94 drive the two gear rings 82 to rotate, and the two gear rings 82 drive the two triangular chucks 81 to rotate synchronously, thereby causing the tubular steel component to rotate. This makes it easier to keep the cutting system 12 stationary while the steel component rotates automatically for cutting. This cutting method can perform circumferential cutting on the workpiece, resulting in high cutting neatness, and it conforms to the method of mutual cooperation of the two cutting methods in this application.

[0045] Furthermore, the transmission rod includes two rotating sleeves 92 and a sliding rod 91. The two rotating sleeves 92 are respectively fixedly connected to two gears 94. Both gears 94 are rotatably connected to the rotating sleeves 92 and the mounting plate 83. One end of the sliding rod 91 is fixedly connected to the rotating sleeve 92, and the other end slides through the other rotating sleeve 92. The distance between the two mounting plates 83 needs to be adjusted during use. Therefore, the sliding rod 91 in the transmission rod can slide in the transmission sleeve, which can not only realize the transmission of power, but also realize the adjustment of the distance between them.

[0046] Further, the second driving mechanism 11 comprises a third motor 112 and a screw rod 111, the surface of the mounting seat 5 is provided with two sliding grooves, two mounting plates 83 are respectively and slidably connected in the two sliding grooves, the screw rod 111 is rotatably connected in the sliding groove and is provided with two opposite threads at the midpoint thereof, the two mounting plates 83 are respectively threadedly connected with the two ends of the screw rod 111, the third motor 112 is fixedly installed at the end of the mounting seat 5, the output shaft port of the third motor 112 is fixedly connected with the screw rod 111, the screw rod 111 is driven to rotate by the third motor 112, thereby driving the two mounting plates 83 to relatively slide, and the triangular chuck 81 is arranged on the mounting plate 83, so that the distance between the two can be adjusted, thereby facilitating the two to be far away from each other to leave a space for the two polishing discs 123 to be located in the middle, and then the two are close to each other to make the cutting end contact with the polishing disc 123, and the movement between the two can also adapt to the use of the auxiliary assembly 10 on the plate-shaped steel member of different sizes.

[0047] Further, the side wall of the vertical rod 2 is provided with a vertical groove, the sliding arm 4 is slidably connected in the vertical groove, the first electric telescopic rod 3 is fixedly installed at the top of the vertical rod 2, the output end port of the first electric telescopic rod 3 is fixedly connected with the sliding arm 4, the sliding arm 4 is driven to move vertically by the first electric telescopic rod 3, so that the cutting system 12 is located at a suitable position for normal operation, the surface of the base 1 is provided with a horizontal groove, the bottom of the mounting seat 5 is fixedly installed with a fixed block, the mounting seat 5 is slidably connected with the horizontal groove through the fixed block, and the inner wall of the horizontal groove is fixedly installed with a second electric telescopic rod 6, the output end port of the second electric telescopic rod 6 is fixedly connected with the fixed block, the steel member is fixed on the mounting seat 5, the mounting seat 5 can be moved and adjusted in position by the second electric telescopic rod 6, which further facilitates actual operation and use, and the second electric telescopic rod 6 is mainly applied to the cutting of the plate-shaped steel member, in use, the plate-shaped steel member is fixed by the mounting assembly 8 and the auxiliary assembly 10, so that the cutting line of the plate-shaped steel member is flush with the extension direction of the second electric telescopic rod 6 and is located at the bottom of the cutting system 12, then the entire mounting seat 5 is slid to cooperate with the laser cutting gun 124 in the cutting system 12 to realize cutting.

[0048] Further, the auxiliary assembly 10 comprises a screw rod 101, a steel plate 102 and a roller 103, a rectangular groove is arranged on the surface of the mounting plate 83 close to the position of the mounting seat 5, the steel plate 102 and the rectangular groove are in sliding connection, the roller 103 is uniformly rotatably connected to the surface of the steel plate 102, the screw rod 101 is rotatably inserted into the rectangular groove from the top of the mounting plate 83 and is in threaded connection with the steel plate 102, the auxiliary assembly 10 is installed on the surface of the mounting plate 83, and the working principle is based on the cooperative operation of the screw rod 101, the steel plate 102 and the roller 103. When it is necessary to fix and cut the steel plate 102, first, the plate-shaped steel member is placed on the steel plate 102, so that the bottom thereof is in contact with the roller 103, and the height of the steel plate 102 is adjusted by rotating the screw rod 101. Since the screw rod 101 is rotatably inserted into the rectangular groove from the top of the mounting plate 83 and is in threaded connection with the steel plate 102, according to the threaded transmission principle, when the screw rod 101 rotates, the steel plate 102 slides up and down in the rectangular groove in the vertical direction until the top of the plate-shaped steel member is in contact with the circumferential surface of the triangular chuck 81, at this time, the plate-shaped steel member is clamped on the auxiliary assembly 10 at both ends, the triangular chuck 81 rotates, the plate-shaped steel member can move under the action of friction, and then is cut by the cutting system 12, and the roller 103 can make the plate-shaped steel member more easily slide.

[0049] Further, the steel plate 102 is in “L” shape, one side wall of the steel plate 102 is in contact with the tooth ring 82, so that the plate-shaped steel member cannot move left and right but can only move under the drive of the triangular chuck 81, the anti-skid rubber sleeve 104 is fixedly installed on the circumferential surface of the triangular chuck 81, so that the sliding efficiency of the plate-shaped steel member is higher, and the plate-shaped steel member is more convenient to cut.

[0050] In summary, the advanced mode of laser cutting and cutting knife 125 cutting is adopted. In the initial stage, laser cutting technology is used, the laser cutting position is kept constant, and the tubular steel part is driven to rotate at a constant speed. In this process, the laser precisely acts on the surface of the tubular steel part, and gradually cuts off a circular part. When the cutting process is about to end, at the critical node of completing but not completely cutting off, the cutting knife 125 is quickly switched to cutting. The cutting knife 125 also performs circumferential cutting around the tubular steel part. This unique combination of processes can effectively avoid the problem that slag is easily introduced into the interior of the tubular workpiece during traditional single laser cutting. Because the cutting knife 125 intervenes in time when the laser cutting is about to be completed, it avoids excessive slag generated by continuous laser action, greatly reduces the risk of slag pollution to the interior of the workpiece and affects the subsequent processing. At the same time, compared with the traditional cutting method of directly cutting the workpiece once, the rotating cutting method of rotating the workpiece while keeping the cutting point fixed can significantly improve the flatness and neatness of the cutting surface. During rotation, the cutting point always acts on the workpiece in a stable state, ensuring the consistency and continuity of the cutting path, effectively reducing the cutting deviation caused by the movement of the cutting point or the instability of the workpiece, making the cut edge more neat and smooth, and greatly improving the cutting quality of the tubular steel part, providing a better foundation for subsequent processing procedures.

[0051] In the cutting system 12, the surface of the mounting shaft 126 is provided with a polishing disc 123 on both sides of the turntable 121, which is driven by the fourth motor 122. After cutting is completed, the two steel members are moved away from each other by adjusting the position of the mounting plate 83, the sliding arm 4 is lowered, the polishing disc 123 is placed between the two steel members, and then the steel members are moved close to the polishing disc 123. The fourth motor 122 is started to drive the polishing disc 123 to rotate, achieving polishing of the cutting part, reducing the subsequent manual polishing process, and improving production efficiency.

[0052] For plate-shaped workpieces, the processing method is also ingenious. The plate-shaped workpiece is directly placed on the support plate uniformly provided with rollers 103, the bottom of the plate-shaped workpiece is in good contact with the rollers 103, and the top is in contact with the triangular chuck 81 with a high-friction rubber sleeve 104 on the circumferential surface. When the triangular chuck 81 rotates, it can smoothly drive the plate-shaped workpiece to move, thereby perfectly cooperating with the cutting device for cutting.
