Description

Technical Field

[0001] This invention relates to the field of chain technology, specifically to a high-strength chain production equipment and production process. Background Technology

[0002] Flash butt welding equipment falls under the category of metal cutting and welding equipment manufacturing. It differs from automatic and semi-automatic electric arc welding and plasma arc welding machines, and belongs to the category of resistance welding equipment.

[0003] Chains with higher load-bearing capacity have larger cross-sectional diameters. However, when using flash butt welding equipment, this type of chain can only be welded to chains in a vertical position. Chains lying horizontally cannot be welded and require a separate flash butt welding machine to weld the flipped chain. This is mainly because the chain's large cross-sectional diameter makes it difficult to flip during pulling, and the track's locking grooves are also deeper. However, this welding method has a drawback: when pulled, as the chain passes through the welding seat, the bending structure of the welding seat and the pulling force exerted by the rear chain can cause the weld joint to widen. This risk transforms into a definite outcome during batch welding.

[0004] Therefore, it is necessary to design a high-strength chain production equipment and process that can reduce the pulling force of the chain when it passes through the welding seat and avoid the risk of the gap at the chain welding point being widened. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a high-strength chain production equipment and process that can reduce the pulling force on the chain when it passes through the welding seat, thus avoiding the risk of the gap at the chain weld being widened.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides a high-strength chain production equipment and production process, including a flash butt welding machine, a chain guide rail for chain movement on the flash butt welding machine, a vertical chain unit being inserted into the groove of the chain guide rail, and a welding support seat between two symmetrically arranged chain guide rails, characterized in that it further includes a rotating swing mechanism and two clamping mechanisms, both of which are slidably mounted on the flash butt welding machine via guide rails, each clamping mechanism being provided with a sliding seat, the sliding seat being slidably connected to the guide rail, the rotating swing mechanism including a swinging bent rod capable of rotating and swinging, the two ends of the swinging bent rod being drively connected to the two sliding seats, the swinging bent rod being used to push the sliding seats to slide up and down along the guide rails.

[0007] Preferably, a sliding column is fixedly installed on the sliding seat, and an oblong hole is opened on the swinging rod for the sliding column to be inserted and slid. When the chain is not pushed to move, the angle between the left swing rod and the vertical line is greater than the angle between the right swing rod and the vertical line.

[0008] Preferably, when the chain is pushed to the preset final position, the angle between the right swing arm of the swinging rod and the perpendicular bisector is equal to the angle between the left swing arm of the swinging rod and the perpendicular bisector before the swinging rod moves.

[0009] Preferably, it also includes a vertical adjustment mechanism, which is used to drive the entire rotating swing mechanism to move vertically upward or downward. After the adjustment is completed, the left and right clamping mechanisms clamp the vertical chain unit at the preset final movement position.

[0010] Preferably, the rotary swing mechanism includes an electric push rod, a mounting base, and a rotary push plate. The mounting base is fixedly mounted on the displacement seat of the vertical adjustment mechanism. The swinging rod is rotatably mounted on the mounting base via a rotating seat. A sliding column is fixedly provided on the swinging rod. A horizontal waist-shaped hole for the sliding column to slide is provided on the rotary push plate. The rotary push plate is fixedly mounted on the output end of the electric push rod, and the electric push rod is fixedly mounted on the mounting base.

[0011] Preferably, the vertical adjustment mechanism includes a displacement seat, a screw, a nut, and a support rotating seat. The support rotating seat is fixedly installed on the flash butt welding machine, the screw is rotatably installed on the support rotating seat, the nut is fixedly connected to the displacement seat through a connecting plate, the nut is engaged with the screw, and one side of the support rotating seat is in contact with the displacement seat.

[0012] Preferably, the clamping mechanism includes an electric push rod II, two clamping arms and a push plate. The electric push rod II is fixedly installed on the sliding seat through a push rod connecting seat. The clamping arms are rotatably installed on the sliding seat through a rotating shaft. One end of the push plate is hinged to the tail of the clamping arm through a hinge rod. The output end of the electric push rod II is fixedly connected to the push plate. The push plate is horizontally slidable on the push rod connecting seat through a sliding column.

[0013] Preferably, the guide rail includes two guide posts and a guide post seat for mounting the two guide posts, and the guide post seat has guide holes for the guide posts to slide.

[0014] Preferably, a tilt adjustment mechanism is provided between the guide post seat and the flash butt welding machine, and the tilt adjustment mechanism is used to tilt and adjust the position of the guide post seat.

[0015] A manufacturing process for a high-strength chain production equipment includes the following: The chain is clamped by a clamping mechanism, and then the swinging mechanism drives the swinging rod to rotate and swing. The clamping mechanisms on the left and right sides drive the chain to move simultaneously. When the chain is moved to the preset final position, the clamping mechanism releases its grip on the chain, and the rotating swing mechanism drives the swinging rod to reset and rotate. When the specifications of the chain change, the vertical adjustment mechanism is driven to adjust the swinging rod up and down, so that the clamping mechanism can clamp the vertical chain unit at the preset final position.

[0016] The beneficial effects of this invention are as follows: the high-strength chain production equipment and process, based on the operation of a flash butt welding machine, can reduce the pulling force of the chain when it passes through the welding seat by using a clamping and moving chain, thus avoiding the risk of the gap at the chain welding point being widened. At the same time, the movement stroke of the two clamping mechanisms can be quickly adjusted according to different chain specifications, increasing the usability of the equipment.

[0025] 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.

[0026] Example: This invention provides a high-strength chain production equipment and process, such as... Figures 1-6As shown, the flash butt welding machine is equipped with a chain guide rail 2 for the movement of the chain 4. The vertical chain unit 4b is inserted into the groove of the chain guide rail 2. A welding support seat 3 is provided between the two symmetrically arranged chain guide rails 2. It also includes a rotating swing mechanism 1 and two clamping mechanisms 5. The two clamping mechanisms 5 are slidably installed on the flash butt welding machine through the guide slide rail 6. Each clamping mechanism 5 is provided with a sliding seat 5a. The sliding seat 5a is slidably connected to the guide slide rail 6. The rotating swing mechanism 1 includes a swinging bent rod 1a that can rotate and swing. The two ends of the swinging bent rod 1a are connected to the two sliding seats 5a through a transmission. The swinging bent rod 1a is used to push the sliding seats 5a to slide up and down along the guide slide rail 6. After the vertical chain unit 4b is clamped by two clamping mechanisms 5, it is oscillated by a rotating swing mechanism 1. This causes the swinging bent rod 1a to drive the two sliding seats 5a to slide along the two guide rails 6 respectively. During the sliding, when the left sliding seat 5a drives the clamping mechanism 5 to slide upward, the right sliding seat 5a simultaneously drives the clamping mechanism 5 connected to it to slide downward. This staggered movement reduces the pulling force on the horizontal chain unit 4a and the vertical chain unit 4b when passing the welding support 3. Specifically, the pulling force is reduced by having the left clamping mechanism 5 clamp the chain 4b, and when the right clamping mechanism 5 moves, they can move simultaneously. This allows the left clamping mechanism 5 to pull the chain behind its clamping part, while the right clamping mechanism 5 only needs to pull the chain between the two clamping mechanisms 5. The weight that needs to be pulled is smaller, so a large pulling force is not required, thus preventing the gap at the welding position from being widened.

[0027] When the clamping mechanisms 5 on both sides are in motion, the left clamping mechanism 5 needs to pull the chain 4 at a speed that is initially faster than the right clamping mechanism 5, and the final movement distance also needs to be the same. For this purpose, a sliding column 5b is fixedly installed on the sliding seat 5a, and an oblong hole is opened on the swinging rod 1a for the sliding column 5b to be inserted and slid. When the chain 4 is not being pushed, it is in a position... Figure 2 As shown, the angle between the left swing arm of the swinging rod 1a and the perpendicular bisector 7 is greater than the angle between the right swing arm of the swinging rod 1a and the perpendicular bisector 7. When the swinging rod 1a rotates, for the same angle of rotation, the left swing arm of the swinging rod 1a will move the sliding seat 5a a greater distance than the right sliding seat 5a. This means that the left clamping mechanism 5 drives the chain 4 to move a faster distance initially. Figure 3As shown, when the left and right swing arms of the swinging rod 1a are symmetrically arranged, the subsequent movement speed will switch, and the speed at which the right swing arm drives the clamping mechanism 5 will be faster than the speed at which the left clamping mechanism 5 moves. When the chain 4 is pushed to the preset final position, the angle between the right swing arm of the swinging rod 1a and the perpendicular 7 is equal to the angle between the left swing arm of the swinging rod 1a and the perpendicular 7 before it moves. This positional relationship ensures that the distance the left clamping mechanism 5 rises is equal to the distance the right clamping mechanism 5 falls.

[0028] The explanation that "the left clamping mechanism 5 pulls the chain 4 faster than the right clamping mechanism 5 at the beginning" is because when the chain 4 passes the welding support 3, since it is not a rope, an angle will be formed between the chain 4 and the welding support 3, which will consume a certain distance. Therefore, sufficient buffer gap must be left for this distance.

[0029] Because the chain 4 has different designs, the length of the horizontal chain unit 4a varies for each unit. To ensure the device continues to function, a vertical adjustment mechanism 8 is included. This mechanism drives the rotary swing mechanism 1 to move vertically upwards or downwards. After adjustment, the left and right clamping mechanisms 5 clamp the vertical chain unit 4b at the preset final movement position. Since the swinging rod 1a uses swing motion, its position only needs to be met during adjustment. This ensures that the device continues to function even during swinging. Furthermore, this adjustment function requires the sliding seat 5a to slide on the guide rail 6.

[0030] The rotary swing mechanism 1 includes an electric push rod 1b, a mounting base 1c, and a rotary push plate 1d. The mounting base 1c is fixedly mounted on the displacement seat 8a of the vertical adjustment mechanism 8. The swinging rod 1a is rotatably mounted on the mounting base 1c via a rotating seat. A sliding column 1e is fixedly mounted on the swinging rod 1a. The rotary push plate 1d has a horizontal oblong hole for the sliding column 1e to slide through. The rotary push plate 1d is fixedly mounted on the output end of the electric push rod 1b, which is fixedly mounted on the mounting base 1c. When the swinging rod 1a needs to rotate, the sliding column 1e can be pushed to move by controlling the extension or retraction of the output end of the electric push rod 1b, causing the sliding column 1e to drive the swinging rod 1a to rotate along the rotating seat. When the vertical adjustment mechanism 8 is working, it can drive all the structures mounted on the mounting base 1c to move upward through the displacement seat 8a.

[0031] The vertical adjustment mechanism 8 includes a displacement seat 8a, a screw 8b, a nut 8c, and a support rotating seat 8d. The support rotating seat 8d is fixedly mounted on the flash butt welding machine. The screw 8b is rotatably mounted on the support rotating seat 8d. The nut 8c is fixedly connected to the displacement seat 8a via a connecting plate and engages with the screw 8b. One side of the support rotating seat 8d contacts the displacement seat 8a. By rotating the screw 8b, the screw 8b drives the nut 8c to move upward or downward, which in turn drives the displacement seat 8a to move upward or downward, thereby realizing the vertical adjustment process of the rotary swing mechanism 1.

[0032] The clamping mechanism 5 includes a second electric push rod 5c, two clamping arms 5e, and a push plate 5f. The second electric push rod 5c is fixedly mounted on the sliding seat 5a via a push rod connecting seat. The clamping arms 5e are rotatably mounted on the sliding seat 5a via a rotating shaft. One end of the push plate 5f is hinged to the tail of the clamping arm 5e via a hinge rod 5d. The output end of the second electric push rod 5c is fixedly connected to the push plate 5f. The push plate 5f is horizontally mounted on the push rod connecting seat via a sliding column. Horizontal pushing by the second electric push rod 5c causes the push plate 5f to move horizontally. The push plate 5f, in turn, pushes the two clamping arms 5e to rotate and swing via the hinge rod 5d, allowing the clamping arms 5e to clamp and release the vertical chain unit 4b. The sliding column provides horizontal guidance for the movement of the push plate 5f.

[0033] The guide rail 6 includes two guide posts 6a and a guide post seat 6b for mounting the two guide posts 6a. The sliding seat 5a has a guide hole for the guide posts 6a to slide. The sliding installation of the guide posts 6a and the sliding seat 5a ensures that the sliding seat 5a can slide horizontally.

[0034] A tilt adjustment mechanism 9 is provided between the guide post seat 6b and the flash butt welding machine. The tilt adjustment mechanism 9 is used to tilt and adjust the position of the guide post seat 6b. In order to ensure the guide slide rail 6 guides the sliding seat 5a, the tilt adjustment mechanism 9 is needed for adjustment.

[0035] A manufacturing process for a high-strength chain production equipment includes the following: The chain 4 is clamped by the clamping mechanism 5, and the swinging rod 1a is rotated and swung by the rotating swinging mechanism 1. The clamping mechanisms 5 on the left and right sides drive the chain 4 to move simultaneously. When the chain is moved to the preset final position, the clamping mechanism 5 releases its grip on the chain 4, and the rotating swing mechanism 1 drives the swinging rod 1a to reset and rotate. When the specifications of chain 4 change, the vertical adjustment mechanism 8 is driven to adjust the swinging rod 1a up and down, so that the clamping mechanism 5 can clamp the vertical chain unit 4b at the preset final position.

[0036] This high-strength chain production equipment and process, based on the operation of a flash butt welding machine, reduces the pulling force on the chain when it passes the welding seat by using a clamping and moving chain, avoiding the risk of the gap at the chain weld being widened. At the same time, it can quickly adjust the movement stroke of the two clamping mechanisms according to different chain specifications, increasing the usability of the equipment.

[0037] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
