Description

Technical Field

[0001] This invention relates to the field of slag removal head welding technology, specifically to a slag removal head welding assembly for a slag removal machine and a slag removal machine. Background Technology

[0002] Slag removal head welding requires a combination of electric arc welding and plasma arc welding. Electric arc welding is used to complete the splicing of the main structure, while plasma arc welding is used for surfacing or pre-weld treatment. The steel plate is cut into the required part shape using plasma arc welding. Then, all parts are positioned and clamped using special welding fixtures. After the operator starts the equipment, the welding process is carried out automatically or semi-automatically. When the welding wire comes into contact with the workpiece, an electric arc is generated. The heat of the electric arc melts the metal. As the electric arc moves forward, the molten metal in the pool cools and solidifies, forming a strong weld that connects the various parts of the slag removal head into one piece. Currently, the welding slag and fumes generated during the slag removal head welding process are usually collected and treated using a fixed single suction port.

[0003] However, the negative pressure zone of this method is limited to a small area directly in front of the suction port. Once the welding point moves or dust is generated, the collection efficiency will decrease. To solve this problem, existing welding components are equipped with a flexible suction arm combined with a single suction port to increase the direction of dust and welding slag collection. However, the flexible suction arm mainly relies on manual operation. In actual operation, workers often neglect to adjust it due to their focus on welding, causing the suction port to deviate from the cleaning area. Dust will then spread to the surroundings during the adjustment of the suction port. A single suction port cannot quickly capture the spread dust, affecting efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a slag removal head welding assembly for a slag removal machine and a slag removal machine, so as to solve the problem mentioned in the background art that the air inlet is deviated from the cleaning area, and the smoke and dust will spread to the surroundings during the adjustment of the air inlet, and a single air inlet cannot quickly capture the smoke and dust.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a slag removal head welding assembly for a slag removal machine, comprising: a welding box and a welding head, wherein the welding head is disposed at the bottom of the welding box and is used for welding various components;

[0006] A welding frame, which is fitted around the welding box;

[0007] An alternating vibration assembly is installed inside the welding frame. The alternating vibration assembly includes a second conical cover, four force rollers, and a cam disk. The cam disk rotates in a circular motion to trigger the contacting force rollers to rise and fall, synchronously driving the second conical cover to swing alternately in multiple directions, actively and promptly capturing the smoke and welding slag that diffuse around it.

[0008] The top of the second conical hood is provided with the first conical hood, and the first conical hood is provided with a dust filter structure to trap particulate matter in the smoke and dust for filtration.

[0009] The bottom of the second conical cover is provided with four second rods and four fourth rods. The fourth rods are located on one side of the force roller. The fourth rods drive the second rods to move, so as to realize the self-oscillation of the second conical cover, thereby increasing the oscillation amplitude of the air inlet.

[0010] Preferably, the alternating vibration assembly further includes a processing box, which is disposed inside the welded frame. A first rod is disposed inside the processing box, a first conical cover is disposed at one end of the first rod, and a support frame is sleeved at one end of the first conical cover.

[0011] Preferably, the bottom of the processing box is provided with a reinforcing frame, and the interior of the reinforcing frame is provided with four rotating shafts, and rotating plates are provided on both sides of the four rotating shafts.

[0012] Preferably, a third rod is provided between the inner walls of two adjacent rotating plates, and one end of each of the four fourth rods is provided at one end of the four third rods.

[0013] Preferably, the bottom of the welding frame is provided with a limit frame, the top of the limit frame is provided with a servo motor, and the bottom of the limit frame is provided with a second gear.

[0014] Preferably, the output shaft of the servo motor is connected to a first gear, which meshes with a second gear.

[0015] Preferably, the bottom of the limiting frame is provided with a protective cover to prevent some welding slag from falling onto the gear surface.

[0016] Preferably, the second gear is located on the top of the cam disk and is used to drive the cam disk to rotate in a circular motion so that the four force rollers alternately rise and fall.

[0017] Preferably, a support block is fitted at one end of each of the four fourth rods, and four force rollers are respectively arranged inside the four support blocks. A collection head is provided at one end of each of the four fourth rods for collecting smoke and welding slag.

[0018] The present invention also provides a slag remover, including the aforementioned slag remover head welding assembly.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] In this invention, by setting up a multi-bar linkage mechanism driven by a cam disk, the fume collection hood can achieve active alternating oscillation in multiple directions and with large amplitude during the welding process. This expands the collection range of fume and welding slag from the traditional fixed point to a dynamic sweeping surface, solving the technical defect of existing single inlet where the narrow negative pressure zone causes fume to easily diffuse and escape. The wave-like peristalsis of the hood can generate periodic volume changes inside, forming an auxiliary pumping airflow, which improves the dust collection effect and reduces energy consumption without increasing the fan power. Through the synergistic effect of the above structures, the efficiency and reliability of welding fume treatment are improved in terms of collection range, response speed and energy consumption, ensuring the manufacturing quality and production efficiency of the slag removal head welding assembly.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention provides a welding assembly for a slag removal head of a slag removal machine, as shown in the reference. Figure 1 , Figure 2 and Figure 4 As shown: It includes a welding box 100 and a welding head 110. The welding head 110 is located at the bottom of the welding box 100 and is used for welding various components. The welding box 100 is the main mounting base of the slag removal head welding assembly. The welding head 110 and the welding box 100 are connected by welding. The welding box 100 has a support and fixing structure, a positioning and clamping structure, and an adjustment and adaptation structure installed inside. The support and fixing structure is used to install the welding box 100 and the welding head 110. The positioning and clamping structure can connect the welding box 100 to the welding equipment, that is, the welding head 110 can be connected to the welding equipment. The splicing of the main structure of the slag removal head is completed by arc welding.

[0030] In the manufacturing process of existing slag removal machines, the slag removal head welding components cause fumes to spread in all directions during the adjustment of the air intake. A single intake cannot quickly capture the fumes. In this invention, however, the slag and welding slag that spread in all directions are actively captured in a timely manner by setting up alternating vibration components in more than 200 directions.

[0031] like Figure 2 as well as Figure 3As shown, the welding frame 120 is sleeved around the welding box 100. The welding frame 120 is a hollow sleeve structure. The alternating vibration assembly 200 is sleeved around the welding box 100. The welding box 100 and the welding frame 120 are fixed by welding. Its inner cavity provides installation space and motion guidance for the alternating vibration assembly 200. The alternating vibration assembly 200 includes a second conical cover 205, four force rollers 213, and a cam disk 219. The alternating vibration assembly 200 is a dust collection and driving structure, mainly set in the inner cavity of the welding frame 120. The second conical cover 205 is a dust collection cover, a cover-shaped structure made of soft material, located at the top of the alternating vibration assembly 200, with its opening facing the welding area. The second conical cover 205 is a conical enclosure designed to collect and guide fumes and welding slag. Four force-bearing rollers 213 are driven by rods evenly distributed around the bottom circumference of the second conical cover 205. One end of each force-bearing roller 213 contacts the end face of a cam disk 219. This connection allows the second conical cover 205 to swing freely in multiple directions when pushed by the force-bearing rollers 213. The cam disk 219, a circular disc with a specific undulating profile on one end face, is driven by a motor to rotate around its central axis. The rotation of the cam disk 219 triggers the contacting force-bearing rollers 213 to rise and fall, synchronously driving the second conical cover 205 to swing alternately in multiple directions, actively and promptly capturing the fumes and welding slag spreading from all sides. A first conical cover 203 is located at the top of the second conical cover 205. 3 is a conical cover, located on top of the second conical cover 205, and the two are welded together. The first conical cover 203 has an overall conical structure that is smaller at the top and larger at the bottom. Its lower opening is connected to the upper opening of the second conical cover 205, and its upper end is connected to a negative pressure pipe. The negative pressure pipe is connected to a negative pressure device. After startup, it can transmit power through the pipe to the alternating vibration component 200 to capture fumes and welding slag. The first conical cover 203 is equipped with a dust filter structure to trap particulate matter in the fumes. The cam disk 219 rotates continuously under the drive of the motor. The cam profile on its end face periodically contacts the top of the four force rollers 213. When the protruding part of the cam disk 219 rotates above a certain force roller 213, that force roller 213 is... The downward thrust transmits force to the second conical cover 205, causing it to oscillate and deform in a circular motion. Since the four force rollers 213 are evenly distributed circumferentially, each rotation of the cam disk 219 causes the four force rollers 213 to complete one lifting and lowering action in a circumferential sequence, forming an alternating circumferential lifting and lowering motion. This alternating lifting and lowering action causes the second conical cover 205 to oscillate in multiple directions, sometimes tilting to the left, sometimes to the right, sometimes forward, and sometimes backward. This process expands the range for collecting fumes and welding slag.The space swept by the second conical hood 205 during its swing is larger than the fixed opening range, and the swinging second conical hood 205 can dynamically adjust to follow the direction of smoke and dust diffusion.

[0032] like Figure 2 As shown, the first conical cover 203 is equipped with a dust filter structure, which is mainly composed of multiple layers of metal filter screens. When the dust-laden airflow passes through, large particles of welding slag are trapped by the filter screens, the coarse filter screen traps large particles, and the fine filter screen traps fine dust.

[0033] like Figure 4 as well as Figure 6As shown, the bottom of the second conical cover 205 is provided with four second rods 206 and four fourth rods 211. The second rods 206 are hinged to the bottom of the second conical cover 205. The fourth rods 211 are located on one side of the force roller 213. The force roller 213 rotates on one side of the fourth rod 211. When the force roller 213 moves up and down under the trigger of the cam disk 219, the fourth rod 211 is connected to the force roller 213, and the fourth rod 211 is displaced accordingly. The fourth rod 211 drives the second rods 206 to move. The fourth rod 211 transmits the displacement to the second rods 206 through its connection end with the second rod 206, thereby driving the second rods 206 to move. The bottom edges of the two conical covers 205 are hinged, and the movement of the second rod 206 is converted into a pushing and pulling action on the edges of the second conical covers 205, causing the second conical covers 205 to oscillate, thereby increasing the oscillation amplitude of the air intake. The four fourth rods 211 and the second rod 206 are evenly distributed circumferentially, each independently receiving a drive from the corresponding force roller 213. When the cam disk 219 rotates, the four force rollers 213 rise and fall sequentially in circumferential order. Through the transmission of the fourth rods 211 and the second rod 206, the four edges of the second conical covers 205 are alternately pushed up or pulled back. Through the linkage effect of the fourth rods 211 and the second rod 206, the small lifting stroke of the force rollers 213 is amplified into a larger lifting stroke of the edges of the second conical covers 205. The large swing amplitude and the alternating action of the four second rods 206 make the swing of the second conical cover 205 no longer a passive following motion, but an active swing mode. The increased swing amplitude further expands the space swept by the air intake, covering the diffusion area of ​​welding fumes. The alternating vibration assembly 200 also includes a treatment box 201, which is set inside the welding frame 120 and fixed to the inner wall of the welding frame 120 by welding. The treatment box 201 contains a first rod 202, which is a hollow pipe that passes through the treatment box 201 and extends above it. A first conical cover 203 is set at one end of the first rod 202, and one end of the first rod 202 is connected to the top of the second conical cover 205. One end is connected to the other end, while the other end is connected to the first conical cover 203. A support frame 204 is fitted onto one end of the first conical cover 203. The support frame 204 and the first conical cover 203 are fitted together as a sealed connection to keep the first conical cover 203 stable inside the processing box 201. Welding fumes and slag are captured by the swinging motion of the second conical cover 205 and enter the processing box 201. Under the action of the negative pressure fan, they flow upward along the inner cavity of the second conical cover 205 and enter the first rod 202. The first rod 202 serves as an airflow channel, guiding the dust-laden airflow from the second conical cover 205 into the first conical cover 203. The conical structure of the first conical cover 203 causes the airflow velocity to gradually change during its ascent.This facilitates the settling and separation of particulate matter. After the dust-laden airflow passes through the internal dust-filtering structure of the first conical hood 203, solid particles are trapped, and the purified airflow is discharged from the exhaust port at the top of the first conical hood 203.

[0034] like Figure 6 As shown, a reinforcing frame 207 is provided at the bottom of the processing box 201, and the two are welded together. The reinforcing frame 207 serves as a guide seat, and four rotating shafts 208 are provided inside the reinforcing frame 207. Four guide holes are evenly distributed around the circumference inside the reinforcing frame 207 to accommodate and constrain the movement of the four rotating shafts 208. Rotating plates 209 are provided on both sides of the four rotating shafts 208. Each rotating shaft 208 passes through the upper and lower end faces of the reinforcing frame 207 and can slide along its axial direction within the reinforcing frame 207. The rotating shafts 208 and the reinforcing frame 207 are clearance-fitted to reduce frictional resistance and ensure the smoothness and accuracy of the swing of the rotating shafts 208. A third rod 210 is provided between the inner walls of two adjacent rotating plates 209. One end of each of the four fourth rods 211 is respectively located at one end of the four third rods 210. The reinforcing frame 207 serves as the four rotating shafts 208. The guiding and limiting structure provides a precise lifting and lowering track for the rotating shaft 208. When the rotating shaft 208 is driven by a force from below, the force roller 213 pushes it upward, causing the rotating shaft 208 to tilt upward along the guide hole in the reinforcing frame 207. When the driving force disappears, the rotating shaft 208 falls downward under the action of gravity. The presence of the reinforcing frame 207 ensures that the movement direction of the four rotating shafts 208 is always perpendicular to the end face of the reinforcing frame 207, avoiding the rotating shaft 208 from deflecting or getting stuck during the lifting and lowering process. The rotating plate 209 acts as a connecting bridge between the rotating shaft 208 and the third rod 210, transmitting the movement of the rotating shaft 208 to the third rod 210. When the rotating shaft 208 tilts and swings within the reinforcing frame 207, the second rod 206 fixed on it rises and falls accordingly, thereby causing the third rod 210, which is hinged to the rotating plate 209, to produce a corresponding displacement or swing.

[0035] like Figure 2As shown, a limit frame 215 is provided at the bottom of the welded frame 120, and the two are welded together. A servo motor 216 is provided at the top of the limit frame 215, and the servo motor 216 is fixed to the limit frame 215 by bolts. A second gear 218 is provided at the bottom of the limit frame 215, and the second gear 218 rotates at the bottom of the limit frame 215. The output shaft of the servo motor 216 is driven by a first gear 217, and the first gear 217 meshes with the second gear 218. The servo motor 216 serves as the power source for the entire cam drive system, providing continuous torque output for the rotation of the cam disk 219. When the servo motor 216 is powered on, its output shaft begins to rotate. The rotational power of the output shaft 216 is transmitted to the first gear 217, which rotates synchronously. The external teeth of the first gear 217 mesh with the external teeth of the second gear 218. The rotation of the first gear 217 drives the second gear 218 to rotate in the opposite direction. The second gear 218 is fixedly connected to the cam disk 219. The rotation of the second gear 218 drives the cam disk 219 to rotate synchronously. During the rotation, the cam profile on the end face of the cam disk 219 triggers the four force rollers 213 to alternately rise and fall. Then, through the transmission chain of the fourth rod 211, the third rod 210, the rotating plate 209, the rotating shaft 208, and the second rod 206, the second conical cover 205 is driven to achieve alternating oscillation in multiple directions.

[0036] like Figure 4 as well as Figure 5As shown, a protective cover 220 is provided at the bottom of the limiting frame 215. The protective cover 220 is fixed to the bottom of the limiting frame 215 by welding. The protective cover 220 has a ring structure and is positioned above the meshing area of ​​the first gear 217 and the second gear 218. Its shape is adapted to the contour of the gear set so as to cover the gear meshing area to the maximum extent without interfering with the normal operation of the gears, and to prevent some welding slag from falling into the gear surface. The second gear 218 is set on the top of the cam disk 219. The two are integrally formed by welding to ensure that the rotation of the second gear 218 can be transmitted to the cam disk 219 without relative slippage. The end face of the cam disk 219 has a cam surface with a specific contour. During its rotation, the protruding part of the end face successively contacts the bottom of the four force rollers 213. The four force rollers 213 alternately rise and fall by contacting and pushing the cam disk 219 to drive the cam disk 219 to rotate. Each of the four fourth rods 211 has a support block 212 at one end, and the two are welded together. The four force rollers 213 are respectively set inside the four support blocks 212. The force rollers 213 slide freely along the axial direction of the support blocks 212. Each of the four fourth rods 211 has a collection head 214 at one end for collecting fumes and welding slag. Since the four force rollers 213 are evenly distributed around the cam disk 219, each time the cam disk 219 rotates once, the four force rollers 213 complete one rising and falling action in circumferential order. When the cam disk 219 rotates, the cam profile on its end face pushes the upper end of the force roller 213, causing the force roller 213 to slide downward along the inner cavity of the support block 212.After the cam profile rotates, the force roller 213 moves upward along the support block 212 under the action of gravity. The support block 212 provides a linear motion track for the force roller 213, ensuring that the force roller 213 rises and falls in the predetermined direction without deviation. The sliding bushing reduces the frictional resistance between the force roller 213 and the support block 212, making the movement more sensitive. The support block 212 limits the travel of the force roller 213, preventing it from coming off. The collecting head 214 is welded to the fourth rod 211. The collecting head 214 extends outward from the end of the fourth rod 211, and its surface shape is adapted to the direction of smoke flow. During the process of the second conical hood 205 oscillating alternately in multiple directions to capture smoke, some of the smoke and dust are mixed with the weld... Slag escapes from the bottom edge of the second conical shroud 205. A collection head 214 is located at the end of the fourth rod 211, on the outer periphery of the bottom edge of the second conical shroud 205. It moves synchronously with the fourth rod 211. When the second conical shroud 205 swings, the collection head 214 swings accordingly, performing secondary collection of the slag and fumes escaping from the edge of the second conical shroud 205 and guiding them back into the collection range of the second conical shroud 205. Simultaneously, the swinging of the collection head 214 also creates dynamic airflow disturbance around the second conical shroud 205, further preventing the slag and fumes from spreading to more distant areas. The collection head 214, the fourth rod 211, the third rod 210, and the second rod 206 are interconnected, facilitating the intake of slag and fumes.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
