Description

Technical Field

[0001] This utility model relates to the field of anchor chain manufacturing technology, specifically to an anchor chain welding and forming device. Background Technology

[0002] Anchor chains are specialized chains that connect anchors to the hull and transmit anchor holding force. They are formed by connecting metal parts that are bent into loops. They play a vital role in shipbuilding. In the production of anchor chains, welding is a key step in the formation of the anchor chain. During the welding process, the metal parts need to be aligned and connected smoothly. However, existing anchor chain welding devices have some shortcomings.

[0003] Traditional anchor chain welding mainly relies on manual operation or relatively simple mechanical welding equipment. During the processing, the processing position needs to be constantly adjusted by the operator, which increases the complexity of the operation. Furthermore, as the metal parts are plastically molded into a ring structure during the anchor chain welding process, the high rigidity of the metal parts and the influence of deformation elasticity can easily lead to welding misalignment. Utility Model Content

[0004] The purpose of this utility model is to provide an anchor chain welding and forming device to solve the problems mentioned in the background art, which are that traditional anchor chain welding mainly relies on manual operation or relatively simple mechanical auxiliary welding equipment, requires manual adjustment of the processing position, increases the complexity of operation, and is prone to welding misalignment due to the high rigidity of metal parts and the influence of deformation elasticity during welding.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anchor chain welding and forming device, including a processing table, which is configured as a trapezoidal platform structure. A support frame is provided at the upper end of the processing table, and a welding machine is mounted above the support frame. The welding machine is used for welding the joint of the anchor chain in a ring shape, and serves as the main working equipment for anchor chain welding and forming.

[0006] The interior of the processing table is configured with an inverted Y-shaped guide slide, and the support frame at the top of the processing table is configured with a U-shaped structure. The upper end of the support frame is symmetrically provided with positioning blocks, and the side of the support frame that contacts the upper surface of the processing table is provided with an opening. Each side of the support frame is provided with a set of limiting and shaping components, which are used to clamp the arc-shaped positions on both sides of the anchor chain to maintain the alignment of the docking ports.

[0007] A lifting column is installed on the upper surface of the processing table. The lifting column passes through the opening of the support frame, and a limit support plate is provided at the top of the lifting column. The limit support plate is an L-shaped frame structure, and the plate surface parallel to the processing table is composed of two columns. The main body of the limit support plate is slidably connected to one molding auxiliary frame. The upper ends of the two molding auxiliary frames are slidably connected to one end of the support frame. The support frame has openings on both sides that engage with the positioning welding frame. The upper end of the positioning welding frame is penetrated and installed by a welding machine.

[0008] The above technical solution facilitates rapid and accurate positioning of the anchor chain welding port, ensuring the accuracy of the welding position.

[0009] Preferably, a through-type column structure is provided between the two positioning blocks, and the column structure of the two positioning blocks penetrates the rubber guide block.

[0010] By adopting the above technical solution, as the cylindrical structure of the positioning block penetrates the rubber guide block, the rubber guide block and the positioning block remain parallel and stable.

[0011] Preferably, the upper column of the limiting support plate is provided with plates connected to the bottom end of the positioning welding frame on both sides, and the positioning welding frame is configured as an arc-shaped frame structure.

[0012] The above technical solution provides a position for the installation of the positioning welding frame by using the limiting support plate.

[0013] Preferably, the outer wall of the molding auxiliary frame is configured as a C-shaped grooved pipe structure, and the two molding auxiliary frames are symmetrically arranged at the same horizontal height.

[0014] Using the above technical solution, the C-shaped groove set on the outer wall of the molding auxiliary frame facilitates the fitting and positioning of the inner arc-shaped part of the annular anchor chain.

[0015] Preferably, the limiting and shaping component includes:

[0016] Telescopic column one is symmetrically arranged on both sides of the upper end of the support frame, and telescopic column one is a rod structure with sliding connection at both ends;

[0017] A fixed bracket is connected to one output end of the telescopic column, and the fixed bracket has a C-shaped slot inside that fits the surface of the anchor chain.

[0018] Telescopic column 2 is symmetrically arranged on both sides of the upper end of the support frame, while telescopic column 1 is a rod structure with sliding connection at both ends;

[0019] A steering platform is located at the output end of the telescopic column and is positioned above the shaping bracket.

[0020] The inner clamp is connected to the rotating surface of the steering table, and the inner clamp is configured as a C-shaped open clamping plate structure.

[0021] The above technical solution, with the setting of a limiting and shaping component, provides a stable limiting and clamping structure for the anchor chain during welding and forming.

[0022] Preferably, the first telescopic column and the second telescopic column are aligned at their centers, and the second telescopic column is positioned above the first telescopic column.

[0023] By adopting the above technical solution, telescopic column one and telescopic column two are set in a perpendicular direction to avoid the displacement of telescopic column two during the clamping operation of telescopic column one.

[0024] Preferably, the shaping bracket is slidably connected to the surface of the support frame, and the C-shaped slot inside the shaping bracket is engaged with the inner clamp.

[0025] By adopting the above technical solution, the anchor chain position is limited by the stacked installation of the fixed bracket and the inner clamp.

[0026] Compared with the prior art, the beneficial effects of this utility model are: the anchor chain welding and forming device:

[0027] 1. The three-section sliding connection structure formed by the molding auxiliary frame and the support frame achieves lateral positioning of the inner layer of the anchor chain by adjusting the distance between the two molding auxiliary frames. In conjunction with the C-shaped structure of the inner clamp set inside the shaping bracket, the arc-shaped bending part of the anchor chain is wrapped, so that the end of the one-piece bent ring metal anchor chain is stably placed below the weld joint of the welding machine. As the shaping bracket is pushed and restricted by the telescopic column, the end of the anchor chain is aligned inside the support frame. The semi-enclosed positioning structure of the support frame avoids misalignment caused by the deformation and elasticity of the anchor chain during welding, ensuring the accuracy of the welding position and avoiding weld quality problems caused by welding position deviation, thus ensuring the overall strength and reliability of the anchor chain.

[0028] 2. The main connecting steering platform structure installed on the outside of the inner clamp, after the initial welding of the anchor chain port surface is completed, pushes the inner clamp to maintain its original position via the second telescopic column. Then, the first telescopic column drives the shaping bracket to retract outward. The steering platform drives the inner clamp to rotate and tilt around the center of the anchor chain port where the support bracket is placed, facilitating further welding work on the openings on both sides of the anchor chain port by the welding machine. The opening between the two columns located on the limiting support plate provides an opening for supplementary welding of the missing parts of the anchor chain. By adding welding equipment located below and setting the opening of the support bracket, it is easy to achieve consistent welding treatment of the anchor chain port. The overall structure can be adjusted and optimized according to different specifications of anchor chains, and is suitable for welding various types and sizes of anchor chains. It has strong versatility and flexibility and can meet the needs of different users. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1-6 This utility model provides a technical solution: an anchor chain welding and forming device, including a processing table 1, a guide slide 2, a bearing frame 3, a positioning block 4, a rubber guide block 5, a lifting column 6, a limiting support plate 7, a molding auxiliary frame 8, a support frame 9, a positioning welding frame 10, a welding machine 11, a telescopic column one 12, a shaping bracket 13, a telescopic column two 14, a turning platform 15, and an inner clamp 16;

[0038] Among them, the processing table 1 is configured as a trapezoidal table structure, and a support frame 3 is provided on the upper end of the processing table 1. A welding machine 11 is mounted on the support frame 3. The welding machine 11 is used for welding the anchor chain joints that are shaped into rings, and serves as the main working equipment for anchor chain welding and forming.

[0039] The processing table 1 has an inverted Y-shaped guide slide 2 inside, and the support frame 3 at the upper end of the processing table 1 is U-shaped. The upper end of the support frame 3 is symmetrically provided with positioning blocks 4, and the side of the support frame 3 that contacts the upper surface of the processing table 1 has an opening. A set of limiting molding components is provided on both sides of the support frame 3 to clamp the arc-shaped positions on both sides of the anchor chain to maintain the alignment of the docking ports. A through column structure is provided between the two positioning blocks 4, and the column structure of the two positioning blocks 4 passes through the rubber guide block 5.

[0040] The lifting column 6 is installed on the upper surface of the processing table 1. The lifting column 6 passes through the opening of the support frame 3, and the top of the lifting column 6 is provided with a limit support plate 7. The limit support plate 7 is set as an L-shaped frame structure, and the plate surface of the limit support plate 7 parallel to the processing table 1 is composed of two columns. The main body of the limit support plate 7 is slidably connected to one molding auxiliary frame 8. The upper ends of the two molding auxiliary frames 8 are slidably connected to one end of the support frame 9. The support frame 9 has openings on both sides that are engaged with the positioning welding frame 10. The upper end of the positioning welding frame 10 is penetrated and installed by the welding machine 11. The upper column of the limit support plate 7 has plates on both sides that are connected to the bottom end of the positioning welding frame 10. The positioning welding frame 10 is set as an arc-shaped frame structure. The outer wall of the molding auxiliary frame 8 is set as a C-shaped groove pipe structure. The two molding auxiliary frames 8 are symmetrically arranged at the same horizontal height.

[0041] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, the guide slide 2 inside the processing table 1 is used to coordinate the movement direction of the continuously welded anchor chain sections during the production process, preventing the welded chain-like anchor chains from accumulating on the surface of the support frame 3. The positioning block 4 on the surface of the support frame 3 has a U-shaped structure that cooperates with the arc-shaped support of the molding auxiliary frame 8 to support the arc-shaped surface of the anchor chain. The rubber guide block 5 is a split structure located above the guide slide 2, facilitating the entry of the anchor chain into the guide slide 2. Figure 1-2As shown, the lifting column 6 located at the opening of the support frame 3 is used to adjust the overall height of the structure above the limiting support plate 7, facilitating later maintenance and welding. During the welding process at the anchor connection joint, the limited plastic component restricts the movement of the interface, thus providing supplementary welding space for the untouched parts. When used for supplementary welding, the two plastic auxiliary frames 8 slide and separate along the column of the limiting support plate 7 to prevent the anchor chain from shifting. At the same time, the separated openings cooperate with the bottom opening of the support frame 9 to expose the unwelded parts of the anchor chain for supplementary welding. When in use, the part of the limiting support plate 7 that hangs down towards the processing table 1 is a weighted block that slides within the processing table 1. Figure 2 As shown, this structure supports the weight of the upper-mounted molding auxiliary frame 8, support frame 9, positioning welding frame 10, and welding machine 11. During use, the positioning welding frame 10 located on the upper end of the limiting support plate 7 can be disassembled according to installation needs. As needed for on-site installation, the weld joint of the welding machine 11 should be kept parallel to the support frame 9 and facing the anchor chain end. During use, the support frame 9 and the two molding auxiliary frames 8 form a three-section sliding connection structure. The sliding displacement of the molding auxiliary frame 8 and the support frame 9 is used to cooperate with the loading and unloading of the anchor chain, thereby achieving rapid contact limiting clamping for the anchor chain welding and forming. The entire anchor chain is precisely positioned and limited to ensure the accuracy of the welding position.

[0042] The limiting molding component includes:

[0043] Telescopic column 12 is symmetrically arranged on both sides of the upper end of the support frame 3. The telescopic column 12 is a rod structure with sliding connection at both ends. The telescopic column 12 and the telescopic column 2 14 are aligned at the center and the telescopic column 2 14 is located above the telescopic column 12.

[0044] The fixed bracket 13 is connected to one side of the output end of the telescopic column 12, and the fixed bracket 13 has a C-shaped slot that fits the surface of the anchor chain. The fixed bracket 13 is slidably connected to the surface of the support frame 3, and the C-shaped slot inside the fixed bracket 13 is engaged with the inner clamp 16.

[0045] Telescopic column 2 14 is symmetrically arranged on both sides of the upper end of the support frame 3, and telescopic column 1 12 is a rod structure with sliding connection at both ends;

[0046] The steering platform 15 is located at the output end of the telescopic column 14 and is positioned above the shaping bracket 13.

[0047] The inner clamp 16 is connected to the rotating surface of the turntable 15, and the inner clamp 16 is configured as a C-shaped open clamp plate.

[0048] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, the telescopic columns 12 installed on the plate sections erected on both sides of the upper end of the support frame 3 are as follows: Figure 1As shown, the shaping bracket 13 located at the output end of the telescopic column 12 has a C-shaped opening and a groove that abuts against one end of the molding auxiliary frame 8. This, in conjunction with the molding auxiliary frame 8, provides a stable and precise welding environment for the molding process of the anchor chain, reducing the impact of deformation elasticity on the anchor chain welding interface. The inner clamp 16 located inside the shaping bracket 13 is a C-shaped arc-shaped clamp, such as... Figure 3 and Figure 6 As shown, the inner opening diameter and thickness of the inner clamp 16 are adjusted according to the diameter of the anchor chain. The turntable 15 connected to the top of the inner clamp 16 is a double-layer rotating turntable structure, which is used to drive the inner clamp 16, which is separated from the shaping bracket 13, to rotate and tilt. This allows the anchor chain part driven by the inner clamp 16 to turn below the weld joint of the welding machine 11, increasing the range of the initial welding position and ensuring stable forming of the anchor chain during the welding process. The telescopic column 14 is used to maintain the thrust of the inner clamp 16 in a stable clamping position on the outside of the anchor chain ring metal part during the trial period when the shaping bracket 13 and the inner clamp 16 are separated. This prevents the movement of the inner clamp 16 and the shaping bracket 13 from affecting the yield of the welded product. The anchor chains produced in this device are small and medium-sized anchor chains used to produce anchor chains for use in narrow tunnels and water flow vessels in tunnels.

[0049] Working principle: When using this anchor chain welding and forming device, the metal part initially shaped into a ring-shaped anchor chain structure is placed with the opening to be welded facing upwards from one side of the support frame 3, onto the upper end of the positioning block 4 and the rubber guide block 5. At this time, the two shaping auxiliary frames 8 are pushed to close, reducing the overall width of the shaping auxiliary frames 8, making it easier to fit the anchor chain element onto the surface of the two shaping auxiliary frames 8. The outer arc-shaped opening of the two shaping auxiliary frames 8 is pushed to fit against the inner part of the elliptical ends of the anchor chain. On the side, the support frame 9 is placed at the welding point of the anchor chain end. Then, the positioning welding frame 10 drives the welding machine 11 to be mounted on the upper end of the limiting support plate 7, so that the welding joint of the welding machine 11 is located at the anchor chain end. The installation position and height of the positioning welding frame 10 are combined with the surrounding structure as needed. To achieve separate installation from the limiting support plate 7, it is only necessary to keep the welding joint position of the welding machine 11 at the anchor chain end. As the telescopic column 12 pushes the shaping bracket 13, it further drives the inner clamp 16 to fit against the outer part of the elliptical ends of the anchor chain, thereby restricting the anchor chain forming during welding, improving the safety and reliability of the production process, and reducing the occurrence of safety accidents. According to the welding needs of the anchor chain surface, the shaping auxiliary frame 8 is retracted, the telescopic column 12 retracts the shaping bracket 13, the telescopic column 2 maintains the position of the inner clamp 16, and the turning table 15 located on the telescopic column 2 rotates and tilts to one side according to the anchor chain welding position, which facilitates further expansion and shaping of the welding positions on both sides of the anchor chain, ensuring the accuracy of the welding position and increasing the overall practicality.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
