Description

Technical Field

[0001] This application relates to the field of punching equipment technology, and in particular to a punching equipment and processing technology for forging underwater crimp connector assemblies. Background Technology

[0002] Underwater crimp connectors are mechanical connection devices designed specifically for underwater environments. They combine the fastening principle of crimp connections with waterproof sealing technology, taking into account the strength, waterproofness and pressure resistance of the connection. They are key components in deep-water engineering and have broad application prospects in marine development, underwater infrastructure and other fields.

[0003] Forging is a processing method that uses forging machinery to apply pressure to a metal billet, causing it to undergo plastic deformation to obtain forgings with specific mechanical properties, shapes, and dimensions. Forging includes various processes, such as hammering and punching. In the forging of underwater clamping connector assemblies, punching is often performed on the workpiece to create suitable hole positions. Punching equipment is used during workpiece processing. Conventional punching equipment mainly consists of a worktable and a punching device. The worktable is equipped with a clamping mechanism to hold the workpiece, while the punching device mainly consists of a power unit and a punch. The power unit drives the punch to strike the workpiece vertically downwards, causing the workpiece to break apart and achieve the punching.

[0004] However, existing punching equipment still has some drawbacks in use: First, the punch is prone to wear due to long-term punching of the workpiece and needs to be replaced regularly. However, the punch disassembly and assembly process is troublesome and inconvenient to disassemble and replace, thus affecting production efficiency. Second, after punching is completed, due to the force generated by the punch, the punched edge of the workpiece will tightly abut against the punch, making it difficult for the workpiece to separate from the punch, which in turn brings certain difficulties to the subsequent demolding operation. Summary of the Invention

[0005] This application proposes a punching device and its processing technology for forging underwater clamp connector assemblies. It has the advantages of using connecting parts to connect hydraulic rods and punches, which effectively improves replacement efficiency, and using a movable mechanism to make the punch rotatable, which effectively improves demolding efficiency. It solves the problems of punches being difficult to replace and demolding in existing punching equipment.

[0006] To achieve the above objectives, this application adopts the following technical solution: a punching device for forging underwater crimp connector assemblies, comprising:

[0007] A support frame and a punching mechanism are provided. The punching mechanism includes a hydraulic cylinder, a hydraulic rod, a punch, and a connector. The outer wall of the hydraulic cylinder is fixedly sleeved to the middle of the top of the support frame. The top of the hydraulic rod is movably sleeved to the inside of the hydraulic cylinder, and the bottom of the hydraulic rod abuts against the top of the punch. Both the bottom of the hydraulic rod and the top of the punch have annular grooves, and both the hydraulic rod and the punch are movably engaged with the connector through the annular grooves. The connector consists of two semi-rings connected by bolts. The punch can be installed by assembling the connector, and the punch can be disassembled by disassembling the connector, thereby simplifying the assembly and disassembly process of the punch and improving the convenience of punch removal and replacement.

[0008] Furthermore, the punch consists of an upper column, a lower column, and a fixing member. The upper column is the upper half of the punch, and the lower column is the lower half of the punch. The fixing member is movably mounted on the outer wall of the upper column, and the fixing member consists of a ring and a limiting member. The inner wall of the ring is tightly fitted with the outer wall of the upper column. Two limiting members are fixedly connected to the outer wall of the ring, and the two limiting members are evenly arranged around the ring. The shape of the limiting member is that the upper and lower ends are vertical and the middle is curved. The upper and lower ends of the limiting member are both pointed. The maximum thickness of the fixing member is greater than the thickness of the half-ring of the connecting member.

[0009] Furthermore, it also includes:

[0010] A fixing mechanism is provided below the punching mechanism to provide working space;

[0011] A clamping mechanism is provided at the top of the fixing mechanism to provide a clamping function;

[0012] The punching mechanism is externally fitted with a movable mechanism to reduce the difficulty of demolding.

[0013] Furthermore, the fixing mechanism includes:

[0014] A fixed platform, wherein a bottom hole is provided at the center of the top of the fixed platform;

[0015] The fixed box has a fixing groove on one side of the fixing platform, and the fixing platform is movably engaged with the fixed box through the fixing groove;

[0016] The workbench is provided at the top of the fixed platform, and the four corners of the workbench are connected to the top of the fixed platform by bolts. A workpiece is placed in the middle of the top of the workbench, and the workpiece is located directly below the punching mechanism. A top hole is opened in the middle of the workbench. The top hole is shaped like a frustum, which is narrow at the top and wide at the bottom, and the bottom dimension of the top hole is the same as the bottom hole dimension.

[0017] Furthermore, the number of clamping mechanisms is four, and the four clamping mechanisms are respectively located on the four sides of the worktable. The clamping mechanisms include:

[0018] The clamping frame has its lower half movably engaged with the edge of the worktable, and the clamping frame is connected to the worktable by bolts.

[0019] A clamping member, wherein the upper half of the clamping member is fixedly sleeved with the workpiece, and one end of the clamping member abuts against the workpiece.

[0020] Furthermore, the activity mechanism includes:

[0021] The movable component is movably sleeved on the outside of the punching mechanism, and the inner wall surface of the movable component does not contact the fixed component. The height of the movable component is higher than the combined height of the punch and the connecting component.

[0022] The telescopic component has movable plates fixedly connected to the outer walls of its left and right sides. The top of the movable plates is fixedly connected to the bottom of the telescopic component, and the top of the telescopic component is fixedly sleeved with the top of the support frame.

[0023] The movable component has long grooves on the inner walls of its front and rear sides, and the movable component is movably connected to a set of movable components through the long grooves to help the punch dissipate heat in time.

[0024] The limiting component has short grooves at the bottom of the inner wall surface on the left and right sides of the movable part, and the movable part is movably connected to a set of limiting components through the short grooves. This is used to assist the rotation of the punch and to further assist the timely heat dissipation of the punch.

[0025] The movable part is provided with a deformation component, which is located at the angle between the moving component and the limiting component. There are four deformation components, which are evenly arranged around the movable part to dissipate heat and cool the punch.

[0026] Furthermore, the number of moving components in a set of moving components is two, and the two moving components are symmetrically arranged. The moving components include:

[0027] The movable plate is movably disposed in the long groove of the movable part and does not extend out of the long groove. The top and bottom ends of the movable plate are both designed with bevels, and the two symmetrically arranged movable plates form a V-shape when they are fitted together. The upper and lower ends of the protruding part of the connector with the bolt are both pointed.

[0028] The movable rod has a movable groove inside, which is connected to the long groove. Several movable rods are fixedly connected to one side wall of the movable plate, and the movable rods are movably connected to the movable part through the movable groove. The movable plates located on both sides of the movable rods are connected to the movable part by springs.

[0029] Furthermore, the set of limiting components includes two limiting components, which are symmetrically arranged. Each limiting component comprises:

[0030] The limiting plate is movably disposed in the short groove of the movable part and extends out of the short groove. The top and bottom ends of the limiting plate are both designed with bevels, and the two symmetrically arranged limiting plates form a V-shape when they are fitted together.

[0031] The movable part has a limiting groove inside, and the limiting groove is connected to the short groove. The limiting rod is fixedly connected to one side wall of the limiting plate, and the limiting rod is movably sleeved with the movable part through the limiting groove. The limiting plates located on both sides of the limiting rod are connected to the movable part by springs.

[0032] Furthermore, the deformation component includes:

[0033] The deformable bladder has a deformable cavity inside the movable part, and the deformable cavity is connected to the moving groove and the limiting groove. The upper and lower ends of the deformable bladder are fixedly connected to the deformable cavity of the movable part.

[0034] An inlet component is fixedly connected to the top of the deformation bladder, and the inlet component is fixedly sleeved on the top of the movable component;

[0035] The movable part has several outlet parts fixedly connected inside, with one end of the outlet part being fixedly connected to the inside of the deformation bladder and the other end of the outlet part being connected to the inner ring of the movable part.

[0036] By setting a moving component inside the moving part and a deformation component between the moving component and the limiting component, when the punch and the connecting part continuously move inside and outside the moving part, the connecting part pushes the moving component to move, and the punch pushes the limiting component to move. Thus, the moving component and the limiting component reciprocate to squeeze the deformation component, causing the coolant or cooling gas inside the deformation component to be discharged and contact the surface of the punch. This achieves timely heat dissipation of the punch during continuous high-frequency punching, extends the service life of the punch, and improves the quality of punch use.

[0037] Furthermore, a processing technology for a punching device used in forging underwater press-fit connector assemblies includes the following steps:

[0038] S1. When replacing the punch, first remove the bolts on the connector to separate the connector. Then remove the worn punch and replace it with a new punch. Finally, put the two half rings back together and install the bolts back.

[0039] S2. Before punching, first heat the workpiece to the forging temperature, then transfer the heated workpiece to the top of the worktable, and finally control and adjust the clamping mechanism to stably clamp the workpiece in the middle of the worktable.

[0040] S3. When punching, start the hydraulic cylinder, drive the hydraulic rod to press down at high speed, and simultaneously drive the punch to move. The punch stops after contacting the workpiece and reaching the preset depth.

[0041] S4. After punching, activate the telescopic component to drive the movable component to move slowly downward until the bottom of the movable component touches the top of the workpiece and stops. During this process, the movable component passes through the punch, causing the limiting component and the fixed component to move relative to each other. Then the fixed component separates from the two limiting plates and limits the fixed component. As the limiting plates move downward, they push the punch to rotate inside the punch hole of the workpiece.

[0042] S5. Then start the hydraulic cylinder, drive the hydraulic rod to move slowly upward, and simultaneously drive the punch to return. During this process, the moving part passes through the punch, causing the punch to rotate again. Combined with the opposing force of the moving part, the workpiece is separated from the punch, thus achieving demolding.

[0043] S6. Finally, start the telescopic component, drive the movable component to move slowly upward and return to the original position. During this process, the movable component passes through the punch and the connecting component, causing the connecting component to push the moving component to move, and the punch to push the limiting component to move. As a result, the moving component and the limiting component squeeze the deformation component, causing the coolant or cooling gas in the deformation component to be discharged to contact the surface of the punch.

[0044] S7. After completing the work, first control the clamping mechanism to release the workpiece from the clamp, then remove the workpiece and cool it.

[0045] The beneficial effects of this invention are as follows:

[0046] This application provides a punching device for forging underwater clamp connector assemblies. By disassembling the punching mechanism into a hydraulic cylinder, a hydraulic rod, a punch, and a connector, the connector allows the bottom end of the hydraulic rod and the top end of the punch to abut against each other, effectively achieving a stable connection between the hydraulic rod and the punch. This enables the hydraulic rod to carry the punch synchronously. If the punch needs to be replaced, the connector can be disassembled, effectively simplifying the punch assembly and disassembly process, facilitating punch removal and replacement, and improving production efficiency.

[0047] By setting an active mechanism outside the punching mechanism, and the active mechanism consisting of a moving part, a telescopic part, and a limiting component, and through the assembly design of the punching mechanism, after the punch completes the punching, the moving part moves vertically downward under the control of the telescopic part until the bottom end of the moving part abuts against the top end of the workpiece. Then, the punch and hydraulic rod move vertically upward under the control of the hydraulic cylinder. Finally, the moving part moves vertically upward under the control of the telescopic part. During this process, relative motion occurs between the moving part and the punch, and the limiting component limits the fixed part, causing the punch to rotate within the punched hole of the workpiece. Combined with the abutting force of the moving part, this effectively promotes the separation of the workpiece from the punch, reducing the difficulty of demolding and improving production efficiency.

[0065] 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.

[0066] Example 1: A punching device for forging underwater crimp connector assemblies, including a fixed platform 11, such as... Figures 1-2 , Figure 4The fixed platform 11 has a bottom hole at the center of its top to facilitate the collection of residual material generated during punching, allowing the residual material to fall from the outside of the fixed platform 11 into its interior. A fixing groove is provided on one side of the fixed platform 11, and the fixed platform 11 is movably engaged with the fixed box 12 through the fixing groove. During operation, the fixed box 12 is stably positioned within the fixing groove of the fixed platform 11, thereby receiving residual material from the outside of the fixed platform 11. After operation, the fixed box 12 can be pulled out to clean out the residual material inside. A worktable 13 is provided at the top of the fixed platform 11, and the four corners of the worktable 13 are connected to the fixed platform. The tops of the 11 are connected by bolts, effectively ensuring the stability of the workbench 13 positioned on top of the fixed platform 11. A workpiece 3 is placed in the center of the top of the workbench 13, and the workpiece 3 is located directly below the punching mechanism 5, facilitating the punching operation of the workpiece 3 by the punching mechanism 5. A top hole is provided in the center of the workbench 13. The top hole is shaped like a frustum, narrow at the top and wide at the bottom, and the bottom dimension of the top hole is the same as the bottom hole dimension. The shape of the top and bottom holes effectively ensures that residual material is smoothly discharged into the fixed box 12, preventing residual material from clogging the top and bottom holes and affecting its use. Figures 6-7 Thus, the fixed platform 11, the fixed box 12, and the workbench 13 form a fixed mechanism 1, which is used to provide working space.

[0067] like Figures 6-7 The top of the fixing mechanism 1 is provided with a clamping mechanism 2 for providing clamping function. There are four clamping mechanisms 2, and the four clamping mechanisms 2 are located on the four sides of the worktable 13. The clamping mechanism 2 includes a clamping frame 21 and a clamping member 22. The lower half of the clamping frame 21 is movably engaged with the edge of the worktable 13, and the clamping frame 21 is connected to the worktable 13 by bolts, which effectively ensures the stability of the clamping frame 21 on the worktable 13. The upper half of the clamping member 22 is fixedly sleeved with the workpiece 3, and one end of the clamping member 22 abuts against the workpiece 3. The clamping member 22 is retractable to clamp and release the workpiece 3. It should be noted that the four clamping mechanisms 2 are operated synchronously by the control system, so that the workpiece 3 is subjected to the same thrust from four directions, ensuring that the workpiece 3 is facing the punching mechanism 5 and achieving precise punching.

[0068] like Figure 1 , Figure 8 The support frame 4 is located behind the fixing mechanism 1, and the cross-sectional shape of the support frame 4 is inverted L-shaped, which is used to stably support the punching mechanism 5.

[0069] like Figures 1-5 , Figure 8 The punching mechanism 5 is located above the fixing mechanism 1, and the punching mechanism 5 includes a hydraulic cylinder 51, a hydraulic rod 52, a punch 53, and a connecting piece 54, as shown below. Figure 9 and Figure 10The outer wall of the hydraulic cylinder 51 is fixedly sleeved with the top center of the support frame 4. The top of the hydraulic rod 52 is movably sleeved with the inside of the hydraulic cylinder 51, and the bottom end of the hydraulic rod 52 abuts against the top of the punch 53. When the hydraulic cylinder 51 works, the hydraulic rod 52 can synchronously drive the punch 53 to move vertically, realizing punching and demolding of the workpiece 3. The punch 53 includes an upper column 531 and a lower column 532. The upper column 531 is the upper half of the punch 53, and the lower column 532 is the lower half of the punch 53. The function of the upper column 531 is to realize the self- The lower column 532 rotates to punch the workpiece 3. The bottom end of the hydraulic rod 52 and the top end of the punch 53 are both provided with annular grooves. The hydraulic rod 52 and the punch 53 are movably engaged with the connector 54 through the annular grooves. The connector 54 consists of two half-rings, which are connected by bolts. The punch 53 can be installed by assembling the connector 54, and the punch 53 can be disassembled by disassembling the connector 54, thereby simplifying the assembly and disassembly process of the punch 53 and improving the convenience of disassembling and replacing the punch 53.

[0070] Example 2, based on Example 1, such as Figures 9-10 The punch 53 also includes a fixing member 533. The fixing member 533 is movably provided on the outer wall of the upper column 531. The fixing member 533 is composed of a ring and a limiting member. The inner wall of the ring is tightly fitted with the outer wall of the upper column 531. Two limiting members are fixedly connected to the outer wall of the ring. The two limiting members are evenly arranged around the ring. The shape of the limiting members is that the upper and lower ends are vertical and the middle is curved. The upper and lower ends of the limiting members are both pointed. Under the joint action of the two limiting members, the upper column 531 and the lower column 532 are effectively pushed to rotate together.

[0071] like Figures 1-5 The punching mechanism 5 is externally fitted with a movable mechanism 6 to reduce the difficulty of demolding. The movable mechanism 6 includes a movable part 61, a telescopic part 62, and a limiting component 8, such as... Figure 8 , Figure 11The movable component 61 is movably sleeved on the outside of the punching mechanism 5, and the inner wall surface of the movable component 61 does not contact the fixed component 533, effectively ensuring that the punch 53 carrying the fixed component 533 can freely pass through the movable component 61. The height of the movable component 61 is higher than the combined height of the punch 53 and the connecting component 54, effectively ensuring that the movable component 61 and its internal components fully exert their influence on the punch 53 and the connecting component 54 when moving vertically. The movable component 61 is made of high-temperature resistant heat-insulating material, and the outer wall of the movable component 61 is coated with a heat-insulating coating. When the movable part 61 contacts the workpiece 3, it effectively reduces the heating efficiency of the movable part 61, thereby protecting the internal components of the movable part 61. Movable plates are fixedly connected to the outer walls of the left and right sides of the movable part 61. The top of the movable plate is fixedly connected to the bottom of the telescopic part 62, and the top of the telescopic part 62 is fixedly sleeved with the top of the support frame 4. When the telescopic part 62 works, it can drive the movable part 61 to move vertically, thereby helping the movable part 61 to engage or disengage from the punch 53 and the connecting part 54.

[0072] like Figures 4-5 The bottom of the inner wall surface on the left and right sides of the movable part 61 is provided with short grooves, and the movable part 61 is movably connected to a set of limiting components 8 through the short grooves to assist the rotation of the punch 53. The set of limiting components 8 consists of two components, which are symmetrically arranged. Each limiting component 8 includes a limiting plate 81 and a limiting rod 82. Figures 12-15 The limiting plate 81 is movably disposed in the short groove of the movable part 61 and extends out of the short groove. When the limiting plate 81 and the punch 53 move relative to each other, the limiting plate 81 and the fixing part 533 can provide mutual thrust. The top and bottom ends of the limiting plate 81 are both designed with bevels, and the two symmetrically arranged limiting plates 81 form a V-shape when they are in contact. The shape design of the two limiting plates 81 can effectively limit the limiting part, thereby helping to push the punch 53 to rotate. The movable part 61 has a limiting groove inside, and the limiting groove is connected to the short groove. A limiting rod 82 is fixedly connected to one side wall of the limiting plate 81, and the limiting rod 82 is movably sleeved with the movable part 61 through the limiting groove, which effectively ensures the stability of the limiting plate 81 and the limiting rod 82 on the movable part 61. The limiting plates 81 located on both sides of the limiting rod 82 are connected to the movable part 61 by springs.

[0073] In summary, when the fixing member 533 just contacts the limiting component 8, the sharp corner design of the limiting member allows the fixing member 533 to separate the two limiting components 8. Furthermore, the shape design of the limiting member allows the upper column 531 and lower column 532 to rotate under the limitation of the limiting component 8. Combined with the counterforce of the moving part 61, this effectively promotes the separation of the workpiece 3 from the punch 53, reducing demolding difficulty and improving production efficiency. In addition, since the punch 53 rotates relative to the punched wall of the workpiece 3 after punching, friction occurs between them, which to some extent removes some of the residue and debris adhering to the hole wall and initially flattens the burrs appearing on the hole wall. Furthermore, it can reduce secondary tearing during the punching process and reduce the roughness of the hole edge, thereby allowing for further improvements to the lower column 532. Alternatively, a spiral chip removal groove can be added to the lower column 532 to fully remove chips using the synergistic effect of friction and the spiral chip removal groove. Or, a stepped design can be added to the lower column 532 to eliminate burrs by radial extrusion in conjunction with friction. The maximum thickness of the fixing member 533 is greater than the semi-circular thickness of the connecting member 54. From a top view, the fixing member 533 can extend out of the connecting member 54, so that when the moving member 61 moves relative to the punch 53, the limiting component 8 can contact the limiting member inside the fixing member 533, thereby assisting the rotation of the punch 53.

[0074] In Example 3, based on Example 2, the movable mechanism 6 further includes a moving component 7 and a deformation component 9, specifically:

[0075] like Figures 2-3 The inner walls of the front and rear sides of the movable part 61 are provided with elongated grooves, and the movable part 61 is movably connected to a set of moving components 7 through the elongated grooves to help dissipate heat from the punch 53 in a timely manner. The set of moving components 7 consists of two moving components 7, which are symmetrically arranged. Each moving component 7 includes a moving plate 71 and a moving rod 72. Figures 11-15The movable plate 71 is movably disposed within the elongated slot of the movable component 61, and the movable plate 71 does not extend beyond the slot, effectively preventing the movable plate 71 from affecting the vertical movement of the punching mechanism 5. The top and bottom ends of the movable plate 71 are both beveled, and the two symmetrically arranged movable plates 71 form a V-shape when fitted together. It should be noted that the upper and lower ends of the protruding portion of the connecting component 54 with the mounting bolts are pointed, thus aiding in separating the two movable plates 71. The movable component 61 has an internal moving groove that communicates with the elongated slot. Several moving rods 72 are fixedly connected to one side wall of the movable plate 71. The movable rod 72 is movably connected to the movable part 61 through the movable groove, which effectively ensures the stability of the movable plate 71 and the movable rod 72 on the movable part 61. The movable plates 71 located on both sides of the movable rod 72 are connected to the movable part 61 by springs. When the movable assembly 7 is not subjected to the external force of the connecting member 54, the springs can push the two movable plates 71 to fit together, thus providing a foundation for the subsequent extrusion deformation assembly 9. When the movable assembly 7 is subjected to the external force of the connecting member 54, the thrust of the connecting member 54 can overcome the springs and push the two movable plates 71 to separate, thereby realizing the movement of the movable rod 72 and the extrusion deformation assembly 9.

[0076] The limiting component 8 also further assists in the timely heat dissipation of the punch 53, such as... Figures 12-15 When the limiting component 8 is not subjected to the external force of the fixing member 533, the spring can push the two limiting plates 81 to fit together, thus providing a foundation for the subsequent extrusion deformation component 9. When the limiting component 8 is subjected to the external force of the fixing member 533, the thrust of the fixing member 533 can overcome the spring and push the two limiting plates 81 to separate, thereby realizing the movement of the limiting rod 82 and extrusion deformation component 9.

[0077] like Figures 11-15The movable part 61 is internally equipped with a deformation component 9, which is located at the angle between the moving component 7 and the limiting component 8. There are four deformation components 9, evenly arranged around the movable part 61. Because the movable part 61 is in a high-temperature environment, the simple mechanical design of the deformation components 9 effectively dissipates heat from the punch 53. Compared to using an electronically controlled cooling system within the movable part 61, this method has a longer service life and lower cost. The deformation component 9 includes a deformation bladder 91, an inlet component 92, and an outlet component 93. The movable component 61 has a deformation cavity inside the opening component 93, which is connected to the moving groove and the limiting groove. The upper and lower ends of the deformation bladder 91 are fixedly connected to the deformation cavity of the movable component 61. When the moving component 7 and the limiting component 8 are not subjected to external force, the two moving plates 71 are in contact with each other, and the two limiting plates 81 are in contact with each other, so that the moving rod 72 is only located in the moving groove and the limiting rod 82 is only located in the limiting groove, so that neither of them contacts the deformation bladder 91. When the moving component 7 and the limiting component 8 are subjected to external force, the two moving plates 71 separate and the two limiting plates 81 separate. Separation at point 81 allows one end of the moving rod 72 and one end of the limiting rod 82 to enter the deformation cavity, thus bringing them into contact with the deformation bladder 91 and compressing it. The top of the deformation bladder 91 is fixedly connected to an inlet component 92, which is also fixedly sleeved on the top of the movable component 61. The inlet component 92 is connected to an external air pump or water pump, providing cooling gas or coolant to the interior of the deformation bladder 91 during operation, thus aiding in timely heat dissipation of the punch 53. The interior of the movable component 61 is fixedly sleeved... There are several outlet parts 93, one end of which is fixedly connected to the inside of the deformation bladder 91, and the other end of which is connected to the inner ring of the movable part 61. When the deformation bladder 91 is subjected to extrusion pressure, the deformation bladder 91 deforms and the internal pressure changes, thereby causing the outlet parts 93 to open and spray out cooling gas or coolant. If it is coolant, it is in the form of a fine mist to fully contact the surface of the punch 53, so as to achieve timely heat dissipation of the punch 53 during continuous high-frequency punching, extend the service life of the punch 53, and improve the quality of use of the punch 53.

[0078] Example 4, based on Example 3, describes a processing technology for a punching device used in forging underwater crimp connector assemblies, such as... Figures 1-15 This includes the following steps:

[0079] S1. When replacing the punch 53, first remove the bolts on the connector 54 to disassemble the connector 54. Then remove the worn punch 53 and replace it with a new punch 53. Finally, merge the two half rings and reinstall the bolts. This effectively simplifies the disassembly and assembly process of the punch 53, making it easier to disassemble and replace the punch 53 and improve production efficiency.

[0080] S2. Before punching, the workpiece 3 is first heated to the forging temperature in the heating furnace so that the workpiece 3 is in a high plasticity state. Then, the heated workpiece 3 is moved to the top of the worktable 13 by the robot arm. Finally, the clamping mechanism 2 is controlled and adjusted to stably clamp the workpiece 3 in the middle of the worktable 13 to ensure the accuracy of the hole position.

[0081] S3. When punching, start the hydraulic cylinder 51, drive the hydraulic rod 52 to press down at high speed, and simultaneously drive the punch 53 to move. After the punch 53 contacts the workpiece 3, the high-temperature metal is sheared and squeezed to deform and fall off to form scrap. The scrap falls into the fixed box 12 through the top hole and bottom hole, and the punch 53 stops after reaching the preset depth.

[0082] S4. After punching, activate the telescopic component 62 to drive the movable component 61 to move slowly downwards until the bottom end of the movable component 61 contacts the top end of the workpiece 3 and stops. During this process, the movable component 61 passes through the punch 53, causing the limiting component 8 and the fixing component 533 to move relative to each other. As a result, the fixing component 533 separates from the two limiting plates 81 and limits the fixing component 533. As the limiting plates 81 move downwards, the punch 53 is effectively pushed to rotate within the punch hole of the workpiece 3.

[0083] S5. Then, start the hydraulic cylinder 51, drive the hydraulic rod 52 to move slowly upward, and simultaneously drive the punch 53 to return. During this process, the moving part 61 passes through the punch 53, causing the punch 53 to rotate again. With the resistance force of the moving part 61, the workpiece 3 is effectively separated from the punch 53, realizing demolding, thereby reducing the demolding difficulty and improving production efficiency.

[0084] S6. Finally, activate the telescopic component 62 to drive the movable component 61 to slowly move upward and return to its original position. During this process, the movable component 61 passes through the punch 53 and the connecting component 54, causing the connecting component 54 to push the moving component 7 to move, and the punch 53 to push the limiting component 8 to move. As a result, the moving component 7 and the limiting component 8 reciprocate to squeeze the deformation component 9, causing the coolant or cooling gas in the deformation component 9 to be discharged and contact the surface of the punch 53. This enables the punch 53 to dissipate heat in a timely manner during continuous high-frequency punching, extends the service life of the punch 53, and improves the quality of use of the punch 53.

[0085] S7. After the work is completed, first control the clamping mechanism 2 to release the workpiece 3 from the clamp, then take out the workpiece 3 and cool it to prevent the workpiece 3 from oxidizing and deforming.

[0086] The working principle of the method of using this invention is as follows:

[0087] When replacing the punch 53, first remove the bolts on the connector 54 to disassemble the connector 54. Then, remove the worn punch 53 and replace it with a new punch 53. Finally, merge the two half rings and reinstall the bolts so that the bottom end of the hydraulic rod 52 and the top end of the punch 53 abut against each other, effectively achieving a stable connection between the hydraulic rod 52 and the punch 53. This effectively simplifies the disassembly and assembly process of the punch 53, making it easier to disassemble and replace the punch 53 and improving production efficiency.

[0088] Before punching, the workpiece 3 is first heated to the forging temperature in the heating furnace, so that the workpiece 3 is in a high plasticity state. Then, the heated workpiece 3 is transferred to the worktable 13 using a robot arm. Finally, the clamping mechanism 2 is controlled and adjusted to stably clamp the workpiece 3 in the middle of the worktable 13 to ensure the accuracy of the hole position.

[0089] When punching, the hydraulic cylinder 51 is activated, driving the hydraulic rod 52 to press down at high speed, and simultaneously driving the punch 53 to move. After the punch 53 contacts the workpiece 3, the high-temperature metal undergoes shearing and extrusion deformation and falls off to form scrap. The scrap falls into the fixed box 12 through the top hole and bottom hole, and the punch 53 stops after reaching the preset depth.

[0090] After punching, the telescopic component 62 is activated, driving the movable component 61 to slowly move downwards until the bottom end of the movable component 61 contacts the top end of the workpiece 3 and stops. During this process, the movable component 61 passes through the punch 53, causing the limiting component 8 and the fixed component 533 to move relative to each other. This causes the fixed component 533 to separate from the two limiting plates 81, and the two limiting plates 81 limit the fixed component 533. As the limiting plates 81 move downwards, they effectively push the punch 53 to rotate within the punch hole of the workpiece 3. Then, the hydraulic cylinder 51 is activated to drive... The hydraulic rod 52 moves upward slowly and simultaneously drives the punch 53 back. During this process, the movable part 61 passes through the punch 53, causing the punch 53 to rotate again. Combined with the resisting force of the movable part 61, the workpiece 3 is effectively separated from the punch 53. Finally, the telescopic part 62 is activated, driving the movable part 61 to move upward slowly and return to its original position. Thus, by utilizing the relative movement of the movable mechanism 6 on the punch 53, the demolding operation of the punch 53 is effectively realized, thereby reducing the demolding difficulty and improving production efficiency.

[0091] After the demolding process is completed, control the clamping mechanism 2 to release the workpiece 3 from the clamp, then remove the workpiece 3 and cool it to prevent oxidation and deformation.

[0092] During the relative movement of the moving mechanism 6 and the punch 53, the punch 53 and the connecting member 54 continuously move inside and outside the moving part 61, causing the connecting member 54 to push the moving component 7 to move, and the punch 53 to push the limiting component 8 to move. As a result, the moving component 7 and the limiting component 8 reciprocate to squeeze the deformation component 9, causing the coolant or cooling gas in the deformation component 9 to be discharged and contact the surface of the punch 53. This achieves timely heat dissipation of the punch 53 during continuous high-frequency punching, extends the service life of the punch 53, and improves the quality of use of the punch 53.
