Description

Technical Field

[0001] This utility model relates to the field of tapping and necking technology, specifically to an integrated tapping and necking device. Background Technology

[0002] Tapping and necking is a composite process in metal processing for tubular or hollow workpieces. It involves first machining internal threads on the inner wall of the workpiece end using a tapping tool, and then using a die or special equipment to radially compress the tapped end, reducing the end diameter and forming a matching structure with the thread. The core purpose of this process is to optimize the assembly performance of the workpiece. It is commonly used in the processing of pipe fittings, connectors, and other parts, such as hydraulic pipe fittings and air pipe connectors. During necking, it is necessary to precisely control the pressure and deformation to avoid damaging the machined thread profile, while ensuring that the size of the necked end precisely matches the mating parts, reducing assembly gaps, improving connection sealing and structural stability. It is widely used in the manufacturing of piping systems in the automotive, machinery, and plumbing industries.

[0003] A search revealed a Chinese patent (CN216758463U) disclosing an adjustable tapping mechanism for a tapping machine. This mechanism includes a tapping machine assembly comprising a body assembly and a tapping mechanism assembly. When a tool replacement is needed, a set of tapping heads is slid from the second groove to the first groove via a slider. The tool is rotated when the threaded head aligns with the threaded hole, achieving a connection through the threaded connection between the threaded head and the threaded hole. Disassembly is achieved by reversing the above steps. Unused tapping heads rotate outwards parallel to the mounting plate via the rotation of the shaft, ensuring that unused tapping heads do not interfere with tapping. A connector inserted into the socket prevents interference with the mounting plate during rotation. Furthermore, a hexagonal bolt connecting to the bottom of the top plate allows for the replacement of other tapping heads, enhancing practicality.

[0004] The aforementioned patent proposes to use a tapping mechanism to process workpieces to form internal threads. However, in actual use, this mechanism can only complete tapping alone. If the workpiece needs to be narrowed, it needs to be transferred to a special equipment for secondary processing. It is impossible to achieve simultaneous tapping and narrowing. Therefore, we propose an integrated tapping and narrowing device. Utility Model Content

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.

[0018] Example 1: Please refer to Figures 1-8 This utility model provides a technical solution: a tapping and necking integrated device, including a workbench 1, an mounting plate 2 on one side of the surface of the workbench 1, a necking component 4 on the mounting plate 2, an mounting plate 6 on the other side of the surface of the workbench 1, a tapping component 7 on the mounting plate 6, a feeding rail 5 on the side of the necking component 4 near the tapping component 7, the feeding rail 5 is used to transport the processed cylindrical workpiece 9 to the tapping component 7, a feeding rail 3 on the side of the necking component 4 away from the feeding rail 5, the feeding rail 3 is used to put the cylindrical workpiece 9 onto the necking component 4 for processing, and a discharging rail 8 on the side of the tapping component 7 away from the feeding rail 5, the discharging rail 8 is used for discharging.

[0019] On one side of the surface of the workbench 1, a mounting plate 2 is installed by bolt fastening. The mounting plate 2 is perpendicular to the surface of the workbench 1 and does not loosen or shift after installation, providing a stable mounting base for subsequent components. The necking component 4 is fixed to the working surface of the mounting plate 2 by positioning holes and bolts. The installation position of the necking component 4 is calibrated to ensure that its processing position is perpendicular to the surface of the workbench 1, meeting the positional accuracy requirements for the necking processing of the cylindrical workpiece 9. On the other side of the worktable 1 surface, a second mounting plate 6 is installed using the same fastening method as the first mounting plate 2. The installation height of the second mounting plate 6 is consistent with that of the first mounting plate 2, and the two are symmetrically distributed on the worktable 1 surface to ensure that the height of the subsequent cylindrical workpiece 9 is matched with the height of the machining station. The tapping assembly 7 is fixed to the working surface of the second mounting plate 6 through a positioning structure. The core machining station of the tapping assembly 7 is horizontally aligned with the machining station of the necking assembly 4 to ensure that the cylindrical workpiece 9 can be accurately transferred to the tapping machining position. On the side of the necking assembly 4 near the tapping assembly 7, a feed rail 5 is fixedly installed horizontally. One end of the feed rail 5 directly connects to the output port of the cylindrical workpiece 9 of the necking assembly 4, and the other end extends to the input station of the cylindrical workpiece 9 of the tapping assembly 7, forming a continuous conveying path. The main function of the feed rail 5 is to transport the cylindrical workpiece 9 processed by the necking assembly 4 from the necking processing station to the processing station of the tapping assembly 7. The entire conveying process requires no manual intervention, ensuring the continuity and accuracy of the transfer of the cylindrical workpiece 9.

[0020] A feeding rail 3 is fixedly installed on the side of the necking assembly 4 away from the feeding rail 5. One end of the feeding rail 3 connects to the input port of the cylindrical workpiece 9 of the necking assembly 4, and the other end is the feeding end of the cylindrical workpiece 9 to be processed. The function of the feeding rail 3 is to receive the cylindrical workpiece 9 to be processed externally and guide the cylindrical workpiece 9 to the processing station of the necking assembly 4, so as to continuously supply the cylindrical workpiece 9 to be processed to the necking assembly 4 and ensure that the necking processing can be carried out continuously.

[0021] On the side of the tapping assembly 7 away from the feed rail 5, a feed rail 8 is fixedly installed at an angle. One end of the feed rail 8 connects to the output port of the cylindrical workpiece 9 of the tapping assembly 7, and the other end extends to the finished product collection area outside the equipment. The function of the feed rail 8 is to transport the finished cylindrical workpiece 9 processed by the tapping assembly 7 from the tapping station to the outside of the equipment, completing the discharge stage of the entire processing flow.

[0022] Example 2: Based on Example 1, such as Figure 3 As shown, the necking assembly 4 includes a fixing block 41 disposed on one side of the surface of the mounting plate 2, a cylinder 3 44 disposed on the other side of the surface of the mounting plate 2, a necking sleeve 45 disposed at one end of the cylinder 3 44, a conical surface 451 disposed on the inner end of the necking sleeve 45, a cylinder 1 42 disposed on one side of the bottom of the feeding rail 3, a cylinder 2 43 disposed on the side of the cylinder 1 42 near the feeding rail 3, a slot 411 opened at the upper end of the fixing block 41, a cylinder 46 disposed at the bottom of the mounting plate 2, a top plate 461 disposed at the output end of the cylinder 46, the top plate 461 being inserted upward into the slot 411, a cylinder 5 47 disposed above the fixing block 41, and a pressure block 1 471 disposed at the output end below the cylinder 5 47.

[0023] On one side of the surface of mounting plate 2, a fixing block 41 is installed by bolt fastening. The fixing block 41 fits tightly against the surface of mounting plate 2 and is not loose after installation. Its position corresponds to the workpiece output end of the feeding rail 3. It is used to receive the cylindrical workpiece 9 to be processed and to provide a processing positioning reference. On the other side of the surface of mounting plate 2, a cylinder 3 44 is installed horizontally. The cylinder body of cylinder 3 44 is connected to mounting plate 2 through a bracket. Its piston rod faces the fixing block 41, and the end of the piston rod is fixed with a necking sleeve 45 by flange or thread connection. The inner end of the necking sleeve 45 is machined with a conical surface 451. The angle of the conical surface 451 matches the necking requirement of the cylindrical workpiece 9 and is used to extrude and form the workpiece end during necking processing.

[0024] On one side of the bottom of the feeding rail 3, a cylinder 42 is fixedly installed by a bracket. The cylinder 42 is horizontally arranged, and its piston rod faces the fixing block 41 of the constriction assembly 4. It is used to push the workpiece to be processed in the feeding rail 3 towards the fixing block 41. On the side of the cylinder 42 close to the feeding rail 3, a cylinder 43 is also horizontally fixed. The installation height of the cylinder 43 is the same as that of the cylinder 42, and its piston rod extends in the same direction as the cylinder 42. It assists the cylinder 42 in completing the workpiece pushing action and ensures that the workpiece to be processed can accurately enter the processing position of the fixing block 41.

[0025] At the upper end of the fixed block 41, a slot 411 is provided vertically. The width of the slot 411 matches the thickness of the top plate 461, and the position of the slot 411 is aligned with the workpiece output port of the feeding rail 3. This slot is used to accommodate the top plate 461 and provide positioning space for the workpiece. At the bottom of the mounting plate 2, a cylinder 46 is fixed by bolts. The cylinder 46 is arranged vertically with its piston rod facing upward. The output end of the piston rod is connected to the top plate 461 by bolts. The top plate 461 is inserted vertically upward into the slot 411 of the fixed block 41. Driven by the cylinder 46, it can move up and down along the slot 411 to push the processed workpiece out of the slot 411 to the feeding rail 5.

[0026] Above the fixed block 41, a cylinder 5 47 is fixedly installed by a gantry or bracket. The cylinder 5 47 is arranged vertically, with its cylinder body fixed to the top of the bracket and the piston rod facing downward. The output end of the piston rod is fixed to a pressure block 1 471 by a threaded connection or a snap-fit. The bottom of the pressure block 1 471 is aligned with the slot 411 of the fixed block 41. It can move up and down under the drive of the cylinder 5 47. When the workpiece to be processed enters the slot 411, the pressure block 1 471 moves downward and presses the workpiece to prevent the workpiece from shifting during the necking process.

[0027] Example 3: Based on Example 1, such as Figure 5 As shown, the tapping assembly 7 includes a motor 72 disposed on one side of the surface of the mounting plate 6, a turntable 71 rotatably mounted on the surface of the mounting plate 6 at the output end of the motor 72, a material groove 711 being opened in the circumferential direction on the side of the turntable 71, a tapping component 73 disposed on the other side of the surface of the mounting plate 6, a cylinder 74 disposed above the turntable 71, and a pressure block 75 disposed at the output end of the cylinder 74.

[0028] On one side of the surface of mounting plate 26, motor 172 is fixedly mounted to the motor bracket with bolts. The output shaft of motor 172 is horizontally arranged and the axis of the output shaft is parallel to the surface of mounting plate 26. The bottom of the motor bracket is in close contact with the surface of mounting plate 26 to ensure that motor 172 does not shake during operation and provides a stable power source for turntable 71. On the surface of mounting plate 26, directly in front of the output end of motor 172, turntable 71 is rotatably mounted through a bearing seat. The central axis of turntable 71 is connected to the output shaft of motor 172 through a coupling. After motor 172 is started, it can drive turntable 71 to rotate uniformly around the central axis. The diameter of turntable 71 is adapted to the size of the cylindrical workpiece 9 being processed to ensure that the workpiece can be placed stably.

[0029] Multiple material grooves 711 are evenly spaced along the circumferential direction on the side of the turntable 71. The size of the groove opening 411 of the material groove 711 matches the outer diameter of the cylindrical workpiece 9, and the groove opening 411 is aligned with the workpiece output end of the conveyor rail 5. When the conveyor rail 5 conveys the narrowed cylindrical workpiece 9 to the turntable 71, the workpiece can be accurately inserted into the material groove 711 and conveyed to the tapping station as the turntable 71 rotates. The setting of multiple material grooves 711 can realize the continuous conveying of workpieces and improve processing efficiency.

[0030] On the other side of the mounting plate 6, a tapping component 73 is fixedly mounted to an adjustable bracket by bolts. The adjustable bracket can adjust the position of the tapping component 73 in the horizontal direction so that the tap axis of the tapping component 73 is aligned with the central axis of the feed groove 711 of the turntable 71. The input end of the tapping component 73 is connected to an external power source, which can drive the tap to rotate and realize axial feed, and is used to tap the cylindrical workpiece 9 in the feed groove 711.

[0031] Above the turntable 71, a cylinder 6 74 is fixedly installed via a gantry or column. The cylinder 6 74 is arranged vertically, with its cylinder body fixed to the top of the support and the piston rod facing downward. The output end of the piston rod is connected to the pressure block 2 75 by bolts. The bottom of the pressure block 2 75 is aligned with the material groove 711 of the tapping station on the turntable 71. When the turntable 71 drives the workpiece to rotate to the tapping station, the cylinder 6 74 drives the pressure block 2 75 to move downward, pressing the workpiece tightly in the material groove 711 to prevent the workpiece from rotating with the tap or shifting during the tapping process, thus ensuring tapping accuracy.

[0032] Based on the above embodiments, the following is the complete working principle of the above embodiments: In use, the cylindrical workpiece 9 to be processed is first placed on the workpiece placement end of the feeding rail 3. The cylindrical workpiece 9 slides along the feeding rail 3 toward the narrowing assembly 4. The cylinder 1 42 on the bottom side of the feeding rail 3 and the cylinder 2 43 near the feeding rail 3 are activated. The piston rod pushes the cylindrical workpiece 9 into the groove 411 of the fixing block 41 in the narrowing assembly 4.

[0033] Next, cylinder 5 47 above the fixed block 41 is activated, and the piston rod drives the pressure block 1 471 to move downward, pressing the cylindrical workpiece 9 in the slot 411 to prevent displacement during processing; then, cylinder 3 44 on the other side of the surface of the mounting plate 1 2 is activated, and the piston rod pushes the end of the necking sleeve 45 to move towards the fixed block 41, and the conical surface 451 at the inner end of the necking sleeve 45 extrudes and forms the end of the cylindrical workpiece 9, completing the necking process.

[0034] After the necking process is completed, cylinder 5 47 drives the pressing block 1 471 to reset upwards, cylinder 46 at the bottom of mounting plate 1 2 starts, and the piston rod drives the top plate 461 to move upwards along the groove 411, pushing the processed cylindrical workpiece 9 out of the groove 411 to the conveying rail 5; the cylindrical workpiece 9 is conveyed from the output port of the necking assembly 4 to the input station of the tapping assembly 7 along the continuous conveying path of the conveying rail 5, and is accurately inserted into the material groove 711 in the circumferential direction on the side of the turntable 71.

[0035] Then, motor 72 on one side of the surface of mounting plate 26 starts, driving turntable 71 to rotate at a constant speed around the central axis through coupling. When the material groove 711 containing the cylindrical workpiece 9 rotates to the tapping position, cylinder 6 74 above turntable 71 starts, and piston rod drives pressure block 2 75 to move downward, pressing the cylindrical workpiece 9 into the material groove 711. At the same time, tapping component 73 on the other side of the surface of mounting plate 26 starts, and the external power source connected to its input end drives the tap to rotate and feed axially, performing tapping on the cylindrical workpiece 9 in the material groove 711.

[0036] After the tapping process is completed, cylinder six 74 drives the pressure block two 75 to reset upwards, and motor one 72 continues to drive the turntable 71 to rotate. When the material groove 711 containing the finished cylindrical workpiece 9 rotates to the docking position with the unloading rail 8, the finished cylindrical workpiece 9 is separated from the material groove 711 and enters the unloading rail 8 on the side of the tapping assembly 7 away from the feeding rail 5. It extends along the unloading rail 8 to the finished product collection area outside the equipment, completing the unloading stage of the entire processing flow.
