Description

Technical Field

[0001] This invention belongs to the field of chain processing technology and specifically relates to an automatic chain weaving and welding machine for anti-skid chains. Background Technology

[0002] A chain is a series of links interlocked to form a bar-shaped metal link. It is primarily used for mechanical transmission and traction. Chains are categorized into drive chains, conveyor chains, traction chains, and specialized chains. This invention focuses primarily on the weaving and manufacturing process of large chains.

[0003] Chain forming is divided into chain braiding and chain welding. The chain braiding process is roughly divided into straightening, automatic intermittent feeding, cutting, bending, and automatic connection. Chain welding can be further divided into processes such as threading, alignment, pressing, welding, and burr removal.

[0004] Currently, there are two main methods for chain braiding: The first is a semi-automatic chain braiding machine. The braiding, straightening, and cutting processes are pre-completed, and workers intermittently feed the chain, controlling the up-and-down movement of the punch to bend the chain and complete the individual chain connections. This method is labor-intensive, dangerous, has low automation and equipment integration, and is no longer suitable for modern processing. The second method is a cam-driven chain braiding machine, which can complete the chain braiding process, but the equipment is purely mechanical, bulky, and has a complex transmission process. The cam drive impacts the mandrel, generating significant noise. Changing the entire forming mechanism when producing different chain models is time-consuming.

[0005] Currently, there are two main methods for chain welding: the first is semi-automatic chain welding, where the chain needs to be manually moved and the welding parts of the chain links need to be aligned manually. The chain links are clamped by pulling the clamping handle and the welding switch is pressed to start welding. This method is labor-intensive, has low automation, low efficiency, and the sparks generated by welding can cause injury to personnel. The second method is large mechanical transmission chain braiding machines, which mostly use gear and cam transmission methods. The equipment is bulky and requires regular maintenance in harsh workshop environments, which is time-consuming and costly.

[0006] Therefore, designing a new type of integrated chain braiding and welding machine that can complete the chain braiding and welding process and overcome the shortcomings of traditional chain braiding and welding machines has become an urgent need for the development of my country's chain processing industry.

[0047] The present invention discloses a chain weaving method for an automatic chain weaving and welding integrated machine for anti-skid chains, as detailed below:

[0048] Step 1: Start and reset the equipment. In the initial state, the drive motor stops rotating, the breaking hydraulic cylinder is retracted, the breaking knife is open, the cutting hydraulic cylinder is retracted, the gripper cylinder is retracted, the feeding cylinder is retracted, the limit cylinder is retracted, the mandrel cylinder is retracted, the ejector cylinder is extended, the vertical hydraulic cylinder is retracted, the horizontal hydraulic cylinder is retracted, the lifting cylinder is retracted, and the toggle cylinder is retracted. The motor rotates until the limit finger is perpendicular to the wire feeding direction.

[0049] Step 2: The wire passes through the feed inlet, and the straightening wheel is placed between the drive wheels. The pre-tension between the wire and the drive wheel is adjusted by the clamping adjustment handle. The straightening drive motor drives the drive gearbox to drive the drive wheel. The drive wheel moves the wire one chain length and then stops. The feeding mechanism sends the wire to the breaking station.

[0050] Step 3: The hydraulic cylinder for breaking the wire extends and drives the breaking connecting rod to reduce the angle between the upper and lower breaking knife holders, and the two breaking knives break the wire.

[0051] Step 4: The drive wheel moves the wire by several chain links. After straightening several sections of wire, the wire is simultaneously conveyed to the cutting station (the distance between the breaking mechanism and the cutting mechanism is several times the length of the wire. During the intermittent conveying time of the drive wheel, the subsequent process is carried out simultaneously. That is, the wire that has been broken by the breaking mechanism may go through several cycles before it reaches the cutting station).

[0052] Step 5: The gripper cylinder drives the movable cylinder to work with the fixed gripper to fix the wire. The cutting hydraulic cylinder extends and moves the cutting cylinder upward through the support pin to cut the wire with the cutting seat.

[0053] Step six: The limit cylinder extends, the adjusting rod is in the set position, the mandrel cylinder extends, and the mandrel is pushed out;

[0054] Step 7: The feeding cylinder extends to place the wire on the mandrel, and one end of the wire contacts the adjusting rod;

[0055] Step 8: The ejector cylinder extends, the ejector rod rotates around the hinge, the ejector presses down, and the wire is fixed in conjunction with the mandrel and adjusting rod;

[0056] Step nine: The gripper cylinder relaxes and the feeding cylinder retracts, completing the feeding process;

[0057] Step 10: The lifting cylinder push rod extends to push the hollow shaft upward and hold it, which drives the limiting finger to move the chain link formed by step 11 into the groove of the mandrel (when step 10 is executed for the first time, the lifting cylinder has no empty stroke because there is no formed chain link).

[0058] Step 11: The vertical hydraulic cylinder extends, the upper part of the forming arm rotates around the guide bar bolt along the inverted V-shaped top block, the upper end of the forming arm opens to both sides according to the arc groove of the cover plate, and the lower end of the forming arm rotates inward to squeeze the wire. The two ends of the wire are squeezed inward by the forming arm and bend inward according to the outline of the mandrel. At this time, the two ends of the wire do not contact the mandrel and are in a straight state, forming a certain angle with the wire conveying direction. The wire is pre-formed, and the vertical hydraulic cylinder retracts.

[0059] Step 12: The horizontal hydraulic cylinder extends, and the arc-shaped groove of the groove forming block re-extrudes and shapes the angled portion that was not formed in Step 11 (the numerical groove of the groove forming block re-extrudes and shapes the chain links parallel to the wire conveying direction, at which point the chain links are fully formed). The chain links at both ends of the wire (still with some misalignment) are fixed by the limiting fingers from Step 10. This incompletely formed chain link, along with the already formed chain at the lower end, is fixed by the mandrel, ejector pin, and adjusting rod. The horizontal hydraulic cylinder retracts, and the lifting cylinder push rod retracts.

[0060] Step 12: The motor starts and drives the hollow shaft to rotate 90 degrees. The limit finger motor is parallel to the wire conveying direction. The lifting cylinder extends and the limit finger reaches the incompletely formed chain link. The ejector cylinder extends and the mandrel cylinder retracts.

[0061] Step thirteen: The actuating cylinder extends to drive the lever to completely fix the incompletely formed chain link to the limiting finger. The actuating cylinder retracts, the lifting cylinder retracts, and the motor rotates until the limiting finger is perpendicular to the wire conveying direction.

[0062] The present invention discloses a welding method for an automatic anti-skid chain weaving and welding integrated machine, as detailed below:

[0063] Step 1: Start the equipment and reset it. The lifting cylinder is in the retracted state, the straightening cylinder is in the retracted state, the chain servo motor is stopped, the clamping hydraulic cylinder is in the retracted state, the dead point hydraulic cylinder is in the extended state, the deburring hydraulic rod is in the retracted state, the top support cylinder is in the retracted state, and the welding hydraulic cylinder is in the retracted state.

[0064] Step Two: Manually thread the unwelded chain, braided by the chain braiding machine, into the square limiting groove, from below the fixed pulley to above the triangular bracket. At this point, ensure the chain's intended welding point is facing upwards and that the chain link's left-right position is approximately within the V-shaped groove formed by the two aligning bases (it only needs to be positioned approximately within the V-shaped groove; the precise left-right position will be determined by the clamping mechanism in subsequent steps. If the left-right position is not met, the servo motor can be rotated to the required angle via the control panel to control the chain's movement distance. The section of chain located between the welding station and the chain winding servo motor can be removed later).

[0065] Step 3: Start the welding program. The chain servo motor rotates at a preset angle, and the chain moves accordingly by one chain link length. At this time, the welding position of the chain link is facing upwards and the left and right positions are located in the V-groove of the straightening base (due to the chain link braiding characteristics, when the chain link moves to the welding station in the square groove, the welding position always faces upwards towards the welding mechanism). The lifting cylinder push rod extends and pushes the lifting slider to rise along the lifting rod. At this time, the two straightening arms are located on both sides of the chain link. The straightening cylinder push rod extends and drives the straightening connecting rod, so that the two straightening arms clamp the chain link.

[0066] Step 4: The dead-point hydraulic cylinder retracts, causing the two side swing arms to rotate around the swing arm connecting rod, which raises the top rod. The pressure rods on both sides move towards the center in the pressure rod slide groove under the push of the top rod connecting rod. At this time, the boom connecting rod, the top rod connecting rod, and the pressure rod form a straight line. The pressing hydraulic cylinder push rod extends, the cross arm connecting rod moves downward, and drives the pressing boom to rotate around its central hinge, so that the boom connecting rod, the top rod connecting rod, and the pressure rod move together along the pressure rod slide groove towards the center to press and fix the chain link.

[0067] Step 5: The centering cylinder retracts, the two centering arms open, and the lifting cylinder retracts;

[0068] Step Six: The welding hydraulic cylinder extends, causing the entire welding mechanism to rotate and descend around the hinge of the welding mechanism base. Supported by a pre-set length support rod, the welding hydraulic cylinder remains extended. The push rods at both ends of the top support cylinder extend, and the electrode fixing rod rotates around the connecting rod fixing rod, causing the hinge of the sliding connecting rod to move downwards along the vertical groove of the T-slot plate. This moves the entire welding connecting rod device downwards, causing the welding electrode fixed on the electrode fixing rod to move downwards while adhering to the outer surface of the chain link as the electrode fixing rod rotates. The welding system is powered on for welding. The top support cylinder retracts, and the welding electrode and electrode move upwards along the outside of the chain link. After the top support cylinder retracts, the welding system is powered off, and the welding hydraulic cylinder retracts.

[0069] Step 7: The hydraulic cylinder push rod extends to make the slide rod move along the groove of the grooved plate towards the chain link. At this time, under the action of the spring tension, the roller at the end of the V-shaped connecting rod enters the groove of the grooved plate. The V-shaped connecting rod rotates around the hinge with the slide rod, pushing the cutter holder connecting rod, so that the cutter holder rotates around the hinge with the slide rod. The two cutter holders approach the semi-circular grooves of the two deburring cutters to form a complete circle in the direction of the slide rod's movement. During the movement of the slide rod, the annular burrs on the chain link are removed.

[0070] Preferably, since the two deburring blades are not fixed in a symmetrical position on the two blade holders, the annular burrs will be removed in half at a time, and will not form an annulus that fits onto the chain link.

[0071] Step 8: The deburring hydraulic cylinder push rod retracts, and the deburring mechanism resets;

[0072] Step 9: This completes the welding of one chain link. By repeating the above steps, the entire chain is welded. After the required length of chain is welded, the chain winding servo motor is rotated to pull the entire chain out of the square limit groove, thus completing the welding of the entire chain.

[0073] The beneficial effects of this invention are:

[0074] 1. The present invention uses hydraulic and pneumatic power sources to achieve the required functional actions, avoiding the disadvantages of traditional chain braiding machines that rely on purely mechanical transmission, are bulky, have complex transmission processes, and are difficult to maintain. At the same time, it reduces production noise and equipment vibration, providing workers with a better working environment.

[0075] 2. This invention employs a two-step process of cutting and forming, with the wire length controlled by a feeding mechanism. This allows for processing wires of different sizes by simply replacing the mandrel required for bending and forming. Unlike traditional integrated cutting and forming methods, which require replacing the entire forming mechanism to process different wire sizes, this invention saves significant production time and equipment costs. It is also more suitable for unmanned production lines.

[0076] 3. This invention employs hydraulic bending to achieve wire bending and forming. Traditional chain braiding machines use a cam-driven rotation method that integrates cutting and forming. Because the cutting requires enormous impact force, especially for large chains, this integrated cutting and forming process places a significant impact on the mandrel, leading to frequent mandrel replacements, increased production costs, and reduced efficiency. Furthermore, excessive impact can cause defects in the chain links at the bending points, reducing chain quality. This invention uses hydraulic bending to achieve adjustable pressure for wires of different diameters, and the two-step cutting and forming process avoids excessive impact on the mandrel, preventing damage to the chain links, reducing costs, and improving production efficiency.

[0077] 4. This invention achieves one-time forming of chain links through the design of the forming mechanism. Since the wire has an unsafe bending point at the first bending joint, a second forming is required. The rotation of gears adjusts the angle of the chain links for connection, and simultaneously, the chain links enter the vertical groove of the forming slider. During the next bending of the chain link, the link is fully bent and formed, indirectly achieving one-time forming of the chain links using the same bending and forming mechanism.

[0078] 5. This invention uses a servo motor to control the wire conveying drive, replacing the linkage mechanism, and precisely controls the wire conveying length.

[0079] 6. The present invention employs a breaking device, which is designed for large-diameter wires that require greater cutting force. It also serves a positioning function, ensuring that the cutting device accurately cuts the wire at the breaking position during the cutting process, thus avoiding wire deviation that may occur during a single cut.

[0080] 7. This invention employs a chain servo motor paired with a triangular chuck and fixed pulley to control the chain's path. By controlling the rotation angle, different welding sizes can be achieved. Furthermore, by controlling the servo motor's idle movement, the chain path is faster than traditional cam-and-claw methods and has the function of skipping chain links that do not require welding, making subsequent chain link removal more convenient.

[0081] 8. In the deburring mechanism of the present invention, the deburring knife is fixed on the knife holder in an asymmetrical position with a certain degree of dislocation, so that the annular burr is removed in two semi-annular welding chips in one deburring process, avoiding the phenomenon of two deburring processes or the burr ring still being fitted on the chain link in traditional equipment.

[0141] This invention discloses a chain forming and chain braiding machine method for large chains, as detailed below:

[0142] Step 1: Start and reset the equipment. In the initial state, the drive motor stops rotating, the breaking hydraulic cylinder 3-7 is retracted, the breaking knife 3-13 is open, the cutting hydraulic cylinder 3-1 is retracted, the gripper cylinder 4-5 is retracted, the feeding cylinder 4-1 is retracted, the limit cylinder 4-7 is retracted, the mandrel cylinder 5-22 is retracted, the ejector cylinder 5-15 is extended, the vertical hydraulic cylinder 5-5 is retracted, the horizontal hydraulic cylinder 5-1 is retracted, the lifting cylinder 5-37 is retracted, the toggle cylinder 5-33 is retracted, and the motor rotates to the limit finger 5-40 perpendicular to the wire conveying direction.

[0143] Step 2: The wire passes through the feed inlet 2-1, and the straightening wheel 2-5 is placed between the drive wheel 2-6. The pre-tension between the wire and the drive wheel 2-6 is adjusted by the clamping adjustment handle 2-8. The straightening drive motor 2-9 drives the drive gearbox 2-7 to drive the drive wheel 2-6. The drive wheel 2-6 moves the wire one chain length and then stops. The feeding mechanism 2 sends the wire to the breaking station.

[0144] Step 3: The hydraulic cylinder 3-7 extends and drives the breaking connecting rod 3-9 to reduce the angle between the upper breaking cutter holder 3-10 and the lower breaking cutter holder 3-11, and the two breaking cutters 3-13 break the wire.

[0145] Step 4: Drive wheels 2-6 move the wire by several chain links. After straightening several sections of wire, the wire is simultaneously conveyed to the cutting station (the distance between the breaking mechanism and the cutting mechanism 3 is several times the length of the wire. During the intermittent conveying time of drive wheels 2-6, the subsequent processes are carried out simultaneously. That is, the wire that has been broken by the breaking mechanism may go through several cycles before reaching the cutting station).

[0146] Step 5: The gripper cylinder 4-5 drives the movable cylinder to cooperate with the fixed gripper 4-4 to fix the wire. The cutting hydraulic cylinder 3-1 extends and, through the support pin 3-6, causes the cutting barrel 3-2 to move upward and cut the wire with the cutting seat 3-4.

[0147] Step 6: Limit cylinder 4-7 extends, adjusting rod 4-10 is in the set position, mandrel cylinder 5-22 extends, and mandrel 5-20 is pushed out;

[0148] Step 7: The feeding cylinder 4-1 extends to place the wire on the mandrel 5-20, and one end of the wire contacts the adjusting rod 4-10;

[0149] Step 8: The ejector cylinder 5-15 extends, the ejector connecting rod 5-16 rotates around the hinge, the ejector 5-18 presses down, and the core rod 5-20 and adjusting rod 4-10 fix the wire.

[0150] Step 9: The gripper cylinder 4-5 releases, and the feeding cylinder 4-1 retracts, completing the feeding process.

[0151] Step 10: The push rod of the lifting cylinder 5-37 extends to push the hollow shaft 5-32 upward and hold it, which drives the limiting finger 5-40 to move the chain link extruded and formed in step 11 into the groove of the mandrel 5-20 (when step 10 is executed for the first time, since there is no formed chain link, the lifting cylinder 5-37 is in an empty stroke).

[0152] Step 11: The vertical hydraulic cylinder 5-5 extends, and the upper part of the forming arm 5-10 rotates around the guide block 5-14 along the inverted V-shaped guide block 5-12. The upper end of the forming arm 5-10 opens to both sides according to the arc groove of the cover plate 5-9, and the lower end of the forming arm 5-10 rotates inward to squeeze the wire. The two ends of the wire are squeezed inward by the forming arm 5-10 and bend inward according to the outline of the mandrel 5-20. At this time, the two ends of the wire do not contact the mandrel 5-20 and are in a straight state, forming a certain angle with the wire conveying direction. The wire is pre-formed, and the vertical hydraulic cylinder 5-5 retracts.

[0153] Step 12: The horizontal hydraulic cylinder 5-1 extends, and the arc-shaped groove of the groove forming block 5-4 re-extrudes and shapes the angled portion that was not formed in Step 11 (the vertical groove of the groove forming block 5-4 re-extrudes and shapes the chain links parallel to the wire conveying direction, at which point the chain links are fully formed). The chain links at both ends of the wire (still with some misalignment) are fixed by the limiting fingers 5-40 from Step 10. This incompletely formed chain link, along with the already formed chain at the lower end, is fixed by the mandrel 5-20, the ejector pin 5-18, and the adjusting rod 4-10. The horizontal hydraulic cylinder 5-1 retracts, and the push rod of the lifting cylinder 5-37 retracts.

[0154] Step 12: The motor starts and drives the hollow shaft 5-32 to rotate 90 degrees. The motor of the limit finger 5-40 is parallel to the wire conveying direction. The lifting cylinder 5-37 extends. The limit finger 5-40 moves to the incompletely formed chain link. The ejector cylinder 5-15 extends. The mandrel cylinder 5-22 retracts.

[0155] Step thirteen: the actuating cylinder 5-33 extends to drive the lever 5-34 to actuate the incompletely formed chain link so that it is completely fixed by the limiting finger 5-40. The actuating cylinder 5-33 retracts, the lifting cylinder 5-37 retracts, and the motor rotates until the limiting finger 5-40 is perpendicular to the wire conveying direction.

[0156] The welding method of this automatic chain welding machine is as follows:

[0157] Step 1: Start the equipment and reset it. The lifting cylinder is in the retracted state, the alignment cylinder 6-7 is in the retracted state, the chain servo motor 6-10 is paused, the clamping hydraulic cylinder 7-1 is in the retracted state, the dead point hydraulic cylinder 7-7 is in the extended state, the deburring hydraulic rod is in the retracted state, the top support cylinder 9-5 is in the retracted state, and the welding hydraulic cylinder 9-8 is in the retracted state.

[0158] Step 2: Manually thread the unwelded chain into the square limiting groove 6-9, from below the fixed pulley 6-12 to above the triangular bracket 6-11. At this point, ensure that the part of the chain to be welded is facing upwards and that the left and right position of the chain link is approximately within the V-shaped groove formed by the two aligning bases 6-8 (it only needs to be placed in an approximate position within the V-shaped groove; the precise left and right position will be determined by the clamping mechanism 7 in a subsequent step. If the left and right position is not met, the servo motor can be rotated to the required angle on the control panel to control the chain movement distance. The section of chain located between the welding station and the chain winding servo motor 6-10 can be removed later).

[0159] Step 3: Start the welding program. The chain servo motor 6-10 rotates at a preset angle, and the chain moves accordingly by one chain link length. At this time, the welding position of the chain link is facing upwards and left and right within the V-groove of the aligning base 6-8 (due to the chain link braiding characteristics, when the chain link moves to the welding station in the square groove, the welding position always faces upwards towards the welding mechanism 9). The lifting cylinder push rod extends and pushes the lifting slider 6-3 to rise along the lifting rod 6-4. At this time, the two aligning arms 6-5 are located on both sides of the chain link. The aligning cylinder 6-7 push rod extends and drives the aligning connecting rod 6-6, so that the two aligning arms 6-5 clamp the chain link.

[0160] Step 4: The dead-point hydraulic cylinder 7-7 retracts, causing the two side swing arms to rotate around the swing arm connecting rod, which raises the top rod. The pressure rods on both sides move towards the center in the pressure rod slide groove 7-6 under the push of the top rod connecting rod 7-12. At this time, the boom connecting rod 7-11, the top rod connecting rod 7-12, and the pressure rod form a straight line. The push rod of the clamping hydraulic cylinder 7-1 extends, and the cross arm connecting rod moves downward, causing the clamping boom to rotate around its central hinge. This causes the boom connecting rod, the top rod connecting rod 7-12, and the pressure rod to move together along the pressure rod slide groove towards the center to clamp and fix the chain link.

[0161] Step 5: Retract the centering cylinder 6-7, open the two centering arms 6-5, and retract the lifting cylinder;

[0162] Step Six: The welding hydraulic cylinder 9-8 extends, causing the entire welding mechanism 9 to rotate and descend around the welding mechanism base 9-10 hinge. Supported by the pre-set length support rod 9-7, the welding hydraulic cylinder 9-8 remains extended. The push rods at both ends of the top support cylinder 9-5 extend, and the welding rod fixing rod 9-3 rotates around the connecting rod fixing rod 9-9. This causes the hinge of the sliding connecting rod 9-4 to move downwards along the vertical groove of the T-slot plate 9-1, driving the entire welding connecting rod device downwards. The welding rod fixed on the welding rod fixing rod 9-3 moves downwards while adhering to the outer surface of the chain link as the welding rod fixing rod 9-3 rotates. The welding system is powered on for welding. The top support cylinder 9-5 retracts, and the welding rod and electrode move upwards along the outside of the chain link. After the top support cylinder 9-5 retracts, the welding system is powered off, and the welding hydraulic cylinder retracts.

[0163] Step 7: The push rod of the deburring hydraulic cylinder 8-1 extends, causing the slide rod 8-7 to move along the groove of the groove plate 8-6 towards the chain link. At this time, under the tension of the spring 8-5, the roller at the end of the V-shaped connecting rod 8-9 enters the groove of the groove plate 8-6. The V-shaped connecting rod 8-9 rotates around the hinge with the slide rod 8-7, pushing the cutter holder connecting rod 8-8, causing the cutter holder to rotate around the hinge with the slide rod 8-7. The two cutter holders approach the semi-circular grooves of the two deburring cutters 8-3 to form a complete circle in the direction of movement of the slide rod 8-7. During the movement of the slide rod 8-7, the annular burrs of the chain link are removed.

[0164] Preferably, since the two deburring blades 8-3 are not fixed in a symmetrical position on the two blade holders, the annular burrs will be removed in half at a time, instead of forming an annulus that fits onto the chain link.

[0165] Step 8: The push rod of the deburring hydraulic cylinder 8-1 retracts, and the deburring mechanism 8 resets;

[0166] Step 9: This completes the welding of one chain link. By repeating the above steps, the entire chain is welded. After the required length of chain is welded, control the chain winding servo motor 6-10 to rotate and pull the entire chain out of the square limit groove 6-9. This completes the welding of the entire chain.

10. The automatic chain weaving and welding machine for anti-skid chains according to claim 9, characterized in that: The welding method is as follows: Step 1: Start the equipment and reset it. The lifting cylinder is in the retracted state, the straightening cylinder is in the retracted state, the chain servo motor is stopped, the clamping hydraulic cylinder is in the retracted state, the dead point hydraulic cylinder is in the extended state, the deburring hydraulic rod is in the retracted state, the top support cylinder is in the retracted state, and the welding hydraulic cylinder is in the retracted state. Step 2: Manually thread the unwelded chain, which has been braided by the chain braiding machine, into the square limiting groove, from below the fixed pulley to above the triangular bracket. At this time, it is necessary to ensure that the part of the chain to be welded is facing upwards and that the left and right positions of the chain links are within the V-shaped groove formed by the combination of the two aligning bases. Step 3: Start the welding program. The chain servo motor rotates at a preset angle, and the chain moves accordingly by one chain link length. At this time, the welding position of the chain link is located in the V-groove of the straightening base. The lifting cylinder push rod extends and pushes the lifting slider to rise along the lifting rod. At this time, the two straightening arms are located on both sides of the chain link. The straightening cylinder push rod extends and drives the straightening connecting rod to make the two straightening arms clamp the chain link. Step 4: The dead-point hydraulic cylinder retracts, causing the two side swing arms to rotate around the swing arm connecting rod, which raises the top rod. The pressure rods on both sides move towards the center in the pressure rod slide groove under the push of the top rod connecting rod. At this time, the boom connecting rod, the top rod connecting rod, and the pressure rod form a straight line. The pressing hydraulic cylinder push rod extends, the cross arm connecting rod moves downward, and drives the pressing boom to rotate around its central hinge, so that the boom connecting rod, the top rod connecting rod, and the pressure rod move together along the pressure rod slide groove towards the center to press and fix the chain link. Step 5: The centering cylinder retracts, the two centering arms open, and the lifting cylinder retracts; Step Six: The welding hydraulic cylinder extends, causing the entire welding mechanism to rotate and descend around the hinge of the welding mechanism base. Supported by a pre-set length support rod, the welding hydraulic cylinder remains extended. The push rods at both ends of the top support cylinder extend, and the welding rod fixing rod rotates around the connecting rod device fixing rod, causing the hinge of the sliding connecting rod to move down along the vertical slide groove of the T-slot plate. This drives the entire welding connecting rod device to move down, causing the welding rod fixed on the welding rod fixing rod to move down close to the outer surface of the chain link while rotating with the welding rod fixing rod. The welding system is powered on for welding, the top support cylinder retracts, and the welding rod and electrode move upward along the outside of the chain link. After the top support cylinder retracts, the welding system is powered off, and the welding hydraulic cylinder retracts. Step 7: The hydraulic cylinder push rod extends to make the slide rod move along the groove of the grooved plate towards the chain link. At this time, the roller at the end of the V-shaped connecting rod enters the groove of the grooved plate under the action of the spring tension. The V-shaped connecting rod rotates around the hinge with the slide rod, pushing the cutter holder connecting rod, so that the cutter holder rotates around the hinge with the slide rod. The two cutter holders approach the semi-circular grooves of the two deburring cutters to form a complete circle in the direction of the slide rod movement. During the movement of the slide rod, the annular burrs of the chain link are removed.
