Description

Technical Field

[0001] This utility model relates to the field of bending sleeve integrated machine technology, and more specifically, to a feeding mechanism for bending sleeve integrated machine. Background Technology

[0002] The integrated bending and sleeve machine is used to produce U-shaped elbows needed for connecting the pipes of two refrigeration units in the refrigeration industry. Then, a U-shaped collar is fitted onto the U-shaped elbow. The U-shaped collar consists of two welded rings, which are convenient to melt the welded rings during the next welding process to seal the U-shaped pipes of the two units and prevent the medium inside the pipes from leaking.

[0003] The integrated bending and sleeve forming machine includes a clamping and distributing mechanism and a feeding mechanism. During the U-shaped elbow forming process, the clamping and distributing mechanism clamps the tube material at the supply position and then releases it, allowing the tube material to fall freely into the receiving groove. The feeding mechanism then delivers the tube material to the bending position. This structural design is complex, and the tube material is prone to warping when it falls into the receiving groove, leading to jamming. Utility Model Content

[0004] The main purpose of this utility model is to provide a feeding mechanism and a bending sleeve integrated machine to solve the technical problem that the material distribution mechanism and feeding mechanism of the existing bending sleeve integrated machine have complex structural designs and are prone to jamming.

[0005] To achieve the above objectives, according to one aspect of the present invention, a feeding mechanism is provided, comprising a material distribution module and a material feeding module;

[0006] The material distribution module includes a receiving plate assembly and a receiving drive assembly. The receiving plate assembly includes a receiving plate with a receiving hole extending along the axial direction of the tube. The output end of the receiving drive assembly is driven to the receiving plate to move the receiving hole to the feeding position where it docks with the tube.

[0007] The feeding module includes a feeding component and a feeding drive component. At least a portion of the output end of the feeding drive component is driven to the feeding component. The pushing part of the feeding drive component has a feeding state. When the pushing part is in the feeding state, the pushing part is disposed at the receiving hole and is movably disposed along the extension direction of the tube to push the tube on the receiving plate.

[0008] This technical solution utilizes a feeding mechanism comprising a distributing module and a feeding module. The distributing module, through the cooperation of a receiving plate assembly and a receiving drive assembly, precisely distributes the tube material from the feeding position to the receiving holes. The receiving holes on the receiving plate extend axially along the tube material, ensuring stable support during the distributing process and restricting radial movement of the tube material. This avoids the tube material warping and jamming problems caused by the lack of radial constraint at the opening of the slot in existing technologies. This technical solution significantly reduces equipment downtime, improves product yield, reduces labor maintenance costs, optimizes the feeding process, and increases production efficiency. Furthermore, compared to existing technologies, this utility model eliminates the need for a clamping distributing structure, resulting in a simpler design and reduced material costs.

[0009] In some embodiments, the pusher assembly further includes:

[0010] A pusher plate is driven to the output end of the pusher drive assembly; the pusher plate is provided with a first mounting hole.

[0011] An elastic element is installed in the first mounting hole. One end of the elastic element abuts against the pusher plate, and the other end of the elastic element is connected to the first end of the pusher. The second end of the pusher is movably provided to extend into the receiving hole.

[0012] The design of the feeding assembly incorporates a feeding plate with an elastic element embedded in its first mounting hole. One end of the elastic element is in close contact with the feeding plate, while the other end is connected to the first end of the pushing unit. The second end of the pushing unit extends to the receiving plate, directly contacting the tube. This structure allows the elastic element to absorb thrust differences caused by fluctuations in tube length during feeding, enabling the pushing unit to independently fine-tune its stroke length and avoid system-wide interference caused by changes in the length of a single tube. The elastic element ensures a smooth transition of the tube during the feeding stage. When the feeding drive assembly moves, the buffering effect of the elastic element allows for precise feeding even with slight fluctuations in tube length, preventing interference and jamming during multiple feeding stages. This ensures that each tube smoothly enters the subsequent process, effectively improving the continuity of the equipment.

[0013] In some embodiments, the receiving plate assembly includes a guide plate disposed on the side of the receiving plate near the pushing portion;

[0014] The guide plate has a first through hole, and the pushing part is slidably connected to the first through hole; when the pushing part is in the pushing state, the second end of the pushing part passes through the first through hole and abuts against the tube material at the receiving hole; and / or,

[0015] A buffer is provided on the side wall of the pusher plate facing the receiving plate. The buffer is located between the pusher plate and the guide plate to buffer the collision between the pusher plate and the guide plate. Specifically, the buffer is a hydraulic buffer.

[0016] In this embodiment, the receiving plate assembly includes a guide plate with a first through hole. The pushing part slides into the first through hole, ensuring precise guidance and smooth operation of the pushing part during the material pushing process. When the pushing part is in the material pushing state, its second end passes through the first through hole and directly contacts the material in the receiving hole, achieving stable and precise material pushing.

[0017] In some embodiments, the pusher assembly further includes:

[0018] A guide shaft is provided, with its axis parallel to the axis of the pushing part. One end of the guide shaft is fixedly connected to the guide plate, and the other end is movably connected to the pusher plate. When the pushing part is in the pushing state, the pusher plate can slide along the guide shaft.

[0019] The feeding assembly integrates a guide shaft design, with its axis parallel to the axis of the pushing unit, ensuring smooth sliding of the feeding plate during the feeding process. One end of the guide shaft is firmly connected to the guide plate, while the other end is movably connected to the feeding plate. When the pushing unit enters the feeding state, the feeding plate slides precisely along the guide shaft, achieving smooth feeding of the tube material. This design eliminates the risk of material jamming and deformation caused by feeding plate misalignment, improves feeding accuracy and reliability, and thus enhances the overall operating efficiency of the equipment.

[0020] In some embodiments, the receiving drive assembly includes a first horizontal drive unit and a lifting drive unit;

[0021] The output end of the first horizontal drive unit and the output end of the lifting drive unit are both connected to the receiving plate to drive the receiving plate to the feeding position or the pushing position where the pushing part can extend into the receiving hole.

[0022] The output end of the first horizontal drive unit is driven to the receiving plate to drive the receiving plate to move along the first horizontal direction, so that the receiving hole is aligned with the unloading position or the pushing part of the pushing component;

[0023] The output end of the lifting drive unit is connected to the receiving plate to drive the receiving plate to lift and lower, so that the receiving plate is at the same height as the unloading position or at the same height as the pushing part of the pushing component.

[0024] The material receiving drive assembly, through the coordinated action of the first horizontal drive unit and the lifting drive unit, achieves precise movement of the receiving plate in both horizontal and vertical directions. The first horizontal drive unit moves the receiving plate along the first horizontal direction, precisely aligning the receiving hole with the unloading position or the pushing part of the pushing component, ensuring that the material can accurately enter or be pushed to the designated position. The lifting drive unit controls the lifting of the receiving plate, ensuring it is at the same height as the unloading position or the pushing part of the pushing component, avoiding material jamming or poor pushing caused by height differences, and guaranteeing smooth material transfer. Through precise adjustment in both horizontal and vertical directions, this solution significantly enhances the stability and efficiency of the equipment, reduces maintenance and manual intervention costs, and achieves a significant increase in production efficiency.

[0025] In some embodiments, the receiving plate assembly further includes:

[0026] The base and the limiting member are fixedly disposed on the base, and the receiving plate is movably disposed above the base so as to move to a limiting position that abuts against the limiting member or to a clearance position that is spaced apart from the limiting member.

[0027] The limiting components on the base ensure that the receiving plate does not exceed the predetermined position during descent, achieving precise alignment of the receiving hole and the pushing part in the height direction. This provides a necessary safety barrier to prevent overload or mechanical damage. This structural design not only improves the stability and reliability of the device but also optimizes the production process, avoiding pushing errors caused by improper receiving plate positioning, reducing equipment downtime for maintenance, and thus significantly improving production efficiency and product yield.

[0028] In some embodiments, the height of the limiting member is adjustable; and / or,

[0029] The base is provided with a buffer, which is located between the base and the receiving plate; the end of the buffer away from the base is set higher than the end of the limiting member away from the base.

[0030] The precise positioning function of the limiting component effectively extends the service life of the equipment, reduces the complexity of debugging and maintenance, and creates favorable conditions for continuous and efficient production. In an alternative embodiment (not shown), the limiting component can be designed as an adjustable screw to accommodate push parts of different heights, further enhancing the versatility and adaptability of the device.

[0031] In some embodiments, the pusher drive component includes:

[0032] The second horizontal drive unit has its output end connected to the receiving plate assembly to drive the receiving plate assembly to move along the tube axis to the bending position.

[0033] The third horizontal drive unit has its non-output end connected to the output end of the second horizontal drive unit, and its output end connected to the pusher assembly. The pusher assembly moves along the tube axial direction to push the tube on the receiving plate at the bending position, thus completing the feeding.

[0034] In some embodiments, the receiving plate assembly includes:

[0035] The first slide rail is vertically arranged.

[0036] The first mounting plate is connected to the upper part of the receiving plate, and the first mounting plate is slidably connected to the first slide rail; the output end of the lifting drive unit is driven to the first mounting plate to drive the first mounting plate to move along the first slide rail, thereby causing the receiving plate to lift.

[0037] The first slide rail is vertically positioned, serving as a guide for the vertical movement of the receiving plate and ensuring precise up-and-down movement. The first mounting plate not only supports the receiving plate but also slides smoothly along the first slide rail under the action of the lifting drive unit. The output of the lifting drive unit is directly connected to the first mounting plate. By driving the first mounting plate to move along the first slide rail, efficient lifting of the receiving plate is achieved, ensuring that the receiving plate is aligned with the height of the feeding position or the pushing part, thus enabling smooth pipe connection or pushing action.

[0038] In some embodiments, the receiving plate assembly includes:

[0039] The second slide rail is arranged along the first horizontal direction and is connected to the upper part of the first mounting plate. The receiving plate is slidably connected to the second slide rail.

[0040] The second mounting plate, on which multiple receiving plates are mounted, is slidably connected to the second slide rail.

[0041] The structure of the receiving plate assembly has been further optimized, achieving efficient movement and positioning of the receiving plate through the combination of a second slide rail and a second mounting plate. Multiple receiving plates are spaced apart on the second mounting plate, enabling synchronous movement of the multiple receiving plates. Specifically, the second slide rail is set along the first horizontal direction to ensure that the receiving plates remain stable during sliding. The second mounting plate, as the carrier of multiple receiving plates, slides with the second slide rail, allowing the receiving plates to move left and right, precisely aligning them to the unloading position.

[0042] In some embodiments, the feeding mechanism further includes:

[0043] The third slide rail is set along the axial direction of the pipe;

[0044] The receiving plate assembly further includes a base, and the receiving plate is connected to the upper part of the base; the base is slidably connected to the third slide rail; at least a portion of the output end of the pusher drive assembly is connected to the base to drive the base to slide along the tube axis on the third slide rail to the bending position.

[0045] To enhance the functionality and flexibility of the feeding mechanism, a third slide rail is introduced, positioned along the axial direction of the tube material to support precise positioning of the receiving plate assembly. The receiving plate assembly is supported by a base, with the receiving plate securely attached to the upper part of the base. A sliding connection is established between the base and the third slide rail, ensuring smooth sliding of the receiving plate along the tube material's axial direction. The push-drive assembly, as the core drive unit, has its output connected to the base, enabling precise control of the base and the receiving plate along the third slide rail to the designated bending position, achieving an integrated movement process from the receiving plate to the bending position.

[0046] In some embodiments, the non-output terminal of the lifting drive unit is connected to the base; the base is provided with a limiting member to limit the descent height of the first mounting plate.

[0047] The limiting component on the base ensures that the first mounting plate will not exceed the predetermined position during descent, achieving precise alignment of the receiving hole and the pushing part in the height direction, providing a necessary safety barrier to prevent overload or mechanical damage.

[0048] This utility model provides a feeding mechanism for an integrated bending and sleeve machine. By designing a receiving plate assembly and a receiving drive assembly, the output end of the receiving drive assembly is driven to the receiving hole, thereby moving the receiving hole to the feeding position where it connects with the tube. The receiving plate assembly includes a receiving plate with a receiving hole extending axially along the tube. This receiving hole restricts the radial movement of the tube, solving the problem of copper tube warping and jamming, and significantly reducing equipment downtime to approximately 2%, far lower than the original 10% downtime rate. It avoids the jamming phenomenon caused by one end of the tube warping when it falls freely into the opening slot, as seen in existing technologies. Furthermore, compared to existing technologies, this utility model eliminates the need for a clamping and material distribution structure, resulting in a simpler design.

[0049] Furthermore, the pusher plate has a first mounting hole, in which an elastic element is installed. One end of the elastic element abuts against the pusher plate, and the other end connects to the first end of the pusher. This spring compensation structure effectively eliminates interference from simultaneous feeding of multiple pushers. Even if the length of a single tube fluctuates, the accuracy and smoothness of the overall feeding can be guaranteed, thus increasing the product yield to approximately 98%, a significant improvement over the previous 95%. This invention reduces the need for manual intervention, decreases maintenance costs, and saves approximately one hour of daily downtime for routine maintenance, greatly improving production continuity and economic efficiency. It significantly enhances equipment stability and production efficiency, and has significant application value and promotion potential for copper tube connection production in the refrigeration industry.

[0063] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0064] Please refer to Figure 1 and Figure 2 The first embodiment of this utility model provides a feeding mechanism for a bending sleeve integrated machine, including a material distribution module 100 and a feeding module 200; the material distribution module 100 includes a receiving plate assembly 110 and a receiving drive assembly 120, the receiving plate assembly 110 includes a receiving plate 111, the receiving plate 111 having a receiving hole 1111 extending axially along the tube material; the output end of the receiving drive assembly 120 is drivenly connected to the receiving plate 111 to drive the receiving hole 1111 to move to a position with the tube material. The feeding position for pipe material connection; the feeding module 200 includes a pushing component 210 and a pushing drive component 220. At least a portion of the output end of the pushing drive component 220 is drivenly connected to the pushing component 210. The pushing part 211 of the pushing drive component 220 has a pushing state. When the pushing part 211 is in the pushing state, the pushing part 211 is disposed at the receiving hole 1111 and is movably disposed along the extension direction of the pipe material to push the pipe material on the receiving plate 111 out. Specifically, the receiving hole 1111 has two openings along its axial direction, which can restrict the radial movement of the pipe material.

[0065] The feeding mechanism of this embodiment includes a distributing module 100 and a feeding module 200. The distributing module 100, through the cooperation of the receiving plate assembly 110 and the receiving drive assembly 120, precisely distributes the tube material at the feeding position into the receiving hole 1111. The receiving hole 1111 on the receiving plate 111 extends along the axial direction of the tube material, ensuring stable support during the distributing process and restricting radial movement of the tube material. This avoids the tube material lifting and jamming problems caused by the lack of radial constraint at the opening of the slot in the prior art. The technical solution of this application significantly reduces equipment downtime, improves product yield, reduces labor maintenance costs, optimizes the feeding process, and improves production efficiency. Furthermore, compared to the prior art, this utility model eliminates the need for a clamping distributing structure, resulting in a simpler design and saving material costs.

[0066] Furthermore, in this embodiment, as Figure 8 and Figure 9 The feeding assembly 210 further includes a feeding plate 212, which is drivenly connected to the output end of the feeding drive assembly 220. The feeding plate 212 has a first mounting hole, in which an elastic element 213 is installed. One end of the elastic element 213 abuts against the feeding plate 212, and the other end is connected to the first end of the pushing part 211. The second end of the pushing part 211 is movably disposed to extend into the receiving hole 1111. Specifically, the elastic element 213 is a spring.

[0067] In this embodiment, the pusher assembly 210 incorporates a pusher plate 212, with an elastic element 213 embedded in its first mounting hole. One end of the elastic element 213 is in close contact with the pusher plate 212, while the other end is connected to the first end of the pusher 211. The second end of the pusher 211 extends to the receiving plate 111, directly contacting the tube. This structure allows the elastic element 213 to absorb thrust differences caused by tube length fluctuations during the pusher process, enabling the pusher 211 to independently fine-tune its stroke length and avoid system-wide interference caused by changes in the length of a single tube. The elastic element 213 ensures a smooth transition of the tube during the pusher stage. When the pusher drive assembly 220 operates, the elastic element 213's buffering effect allows the pusher assembly 210 to accurately perform the feeding operation even with slight fluctuations in tube length, preventing interference and jamming during multiple feeding stages. This ensures that each tube can smoothly enter subsequent processes, effectively improving the continuity of the equipment. In summary, the addition of the elastic element 213 not only optimizes the existing design but also solves the common linkage interference problem in multi-stage feeding, providing strong technical support for the stable operation of the bending and sleeve integrated machine. A spring compensation mechanism is added to the rear end of each pusher 211. The spring absorbs the length fluctuation of a single tube (e.g., a deviation of 0.5mm), allowing the feed rod of that stage to independently fine-tune its stroke, preventing stress transmission to other pushers 211, and ensuring precise and interference-free movement of each pusher 211. In other embodiments not shown in the figure, the material and specifications of the elastic element can be flexibly adjusted according to the characteristics of the tube and the operating conditions of the equipment, further improving the adaptability and processing efficiency of the equipment. Simultaneously, the connection method between the pusher plate 212 and the elastic element 213 can also be modified according to actual needs to meet the tube pushing requirements in different scenarios.

[0068] Furthermore, such as Figure 3 As shown, in this embodiment, the receiving plate assembly 110 includes a guide plate 112, which is disposed on the side of the receiving plate 111 near the pushing part 211.

[0069] The guide plate 112 has a first through hole, and the pushing part 211 is slidably connected to the first through hole; when the pushing part 211 is in the pushing state, the second end of the pushing part 211 passes through the first through hole and abuts against the tube material at the receiving hole 1111; and / or,

[0070] A buffer 214 is provided on the side wall of the pusher plate 212 facing the receiving plate 111. The buffer 214 is located between the pusher plate 212 and the guide plate 112 to buffer the collision between the pusher plate 212 and the guide plate 112.

[0071] In this embodiment, the receiving plate assembly 110 includes a guide plate 112 with a first through hole. The pushing part 211 slides into the first through hole, ensuring precise guidance and smooth operation of the pushing part 211 during the material pushing process. When the pushing part 211 is in the material pushing state, its second end passes through the first through hole and directly contacts the material at the receiving hole 1111, achieving stable and precise material pushing.

[0072] Furthermore, a buffer 214 is fitted to the side wall of the pusher plate 212 facing the receiving plate 111. This buffer 214 acts as a cushion when the pusher plate 212 contacts the guide plate 112, effectively reducing the impact of the collision and improving the smoothness and durability of the mechanism. Through the synergistic effect of the guide plate 112 and the buffer 214, this embodiment optimizes the accuracy and stability of material pushing, reduces equipment wear, and ensures the continuity of the production process and the consistency of the products. In other embodiments not shown, the structure of the guide plate 112 and the buffer 214 can be adjusted according to specific application scenarios to adapt to the characteristics and processing requirements of different materials, achieving wider applicability and higher processing efficiency.

[0073] Furthermore, in this embodiment, the pushing assembly 210 further includes: a guide shaft 215, the axis of which is parallel to the axis of the pushing part 211; one end of the guide shaft 215 is fixedly connected to the guide plate 112, and the other end of the guide shaft 215 is movably connected to the pushing plate 212. When the pushing part 211 is in the pushing state, the pushing plate 212 can slide along the guide shaft 215.

[0074] Specifically, a linear bearing is provided on the pusher plate 212, and the other end of the guide shaft 215 passes through the linear bearing and is slidably connected to the pusher plate 212.

[0075] In this embodiment, the pusher assembly 210 integrates a guide shaft 215, whose axis is parallel to the axis of the pusher 211, ensuring smooth sliding of the pusher plate 212 during the pusher process. One end of the guide shaft 215 is firmly connected to the guide plate 112, while the other end is movably connected to the pusher plate 212. When the pusher 211 enters the pusher state, the pusher plate 212 slides precisely along the guide shaft 215, achieving smooth material feeding. This design eliminates the risk of material jamming and deformation caused by pusher plate misalignment, improves feeding accuracy and reliability, and thus enhances the overall operating efficiency of the equipment. In the most basic design, even without the fine guidance of the guide shaft 215, the pusher task can be completed solely by the direct action of the pusher 211, but this may increase the maintenance frequency of the equipment and reduce long-term operational stability. In summary, the introduction of the guide shaft 215 provides additional radial support and guidance for the pusher process, effectively solving common problems in traditional pusher structures and significantly improving the performance and operational smoothness of the bending and sleeve integrated machine.

[0076] Furthermore, in this embodiment, the receiving drive assembly 120 includes a first horizontal drive unit 121 and a lifting drive unit 122; the output end of the first horizontal drive unit 121 and the output end of the lifting drive unit 122 are both drivenly connected to the receiving plate 111 to drive the receiving plate 111 to the feeding position or the pushing position where the pushing part 211 can extend into the receiving hole 1111;

[0077] Specifically, the output end of the first horizontal drive unit 121 is driven to connect with the receiving plate 111 to drive the receiving plate 111 to move along the first horizontal direction, so that the receiving hole 1111 is aligned with the unloading position or the pushing part 211 of the pushing component 210; the output end of the lifting drive unit 122 is connected to the receiving plate 111 to drive the receiving plate 111 to lift, so that the receiving plate 111 is at the same height as the unloading position or at the same height as the pushing part 211 of the pushing component 210.

[0078] In this embodiment, the receiving drive assembly 120, through the coordinated action of the first horizontal drive unit 121 and the lifting drive unit 122, achieves precise movement of the receiving plate 111 in both horizontal and vertical directions. The first horizontal drive unit 121 is responsible for driving the receiving plate 111 to move along the first horizontal direction, precisely aligning the receiving hole 1111 with the unloading position or the pushing part 211 of the pushing assembly 210, ensuring that the tube material can accurately enter or be pushed to the designated position. The lifting drive unit 122 controls the lifting of the receiving plate 111, keeping it at the same height as the unloading position or the pushing part 211 of the pushing assembly, avoiding material jamming or poor pushing caused by height differences, and ensuring smooth material transmission. Through precise adjustment in both horizontal and vertical directions, this solution significantly enhances the stability and efficiency of the equipment, reduces maintenance and manual intervention costs, and achieves a significant improvement in production efficiency.

[0079] Furthermore, the receiving plate assembly 110 also includes:

[0080] The base 113 and the limiting member 119 are fixedly disposed on the base 113. The receiving plate 111 is movably disposed above the base 113 so as to move to a limiting position that is limited and abuts against the limiting member 119 or to a clearance position that is spaced apart from the limiting member 119.

[0081] Specifically, the height of the limiting member 119 is adjustable.

[0082] The limiting member 119 equipped on the base 113 ensures that the receiving plate 111 does not exceed the predetermined position during descent, achieving precise alignment of the receiving hole 1111 and the pushing part 211 in the height direction, providing a necessary safety barrier to prevent overload or mechanical damage. This structural design not only improves the stability and reliability of the device but also optimizes the production process, avoiding pushing errors caused by improper receiving plate positioning, reducing equipment downtime for maintenance, and thus significantly improving production efficiency and product yield. The synergistic effect of the limiting member 119 and the lifting drive unit 122 ensures precise and controllable pushing processes, providing a stable and reliable material supply for subsequent bending processes and reducing uncertainties in production. In addition, the precise limiting function of the limiting member 119 effectively extends the service life of the equipment, reduces the complexity of debugging and maintenance, and creates favorable conditions for continuous and efficient production. In an alternative embodiment not shown, the limiting member 119 can be designed as an adjustable screw to accommodate pushing parts 211 at different heights, further enhancing the versatility and adaptability of the device. The lifting drive unit 122 can also be replaced with other types of drive devices, such as electric actuators or hydraulic cylinders, to meet specific production needs or environmental conditions. These design changes demonstrate the flexibility and innovation of this device in ensuring production continuity and improving efficiency.

[0083] Furthermore, a buffer 214 is provided on the base 113, and the buffer 214 is located between the base 113 and the receiving plate 111; the end of the buffer 214 away from the base 113 is set higher than the end of the limiting member 119 away from the base 113.

[0084] In this embodiment, a buffer device, such as a spring or elastic pad, is provided between the base 113 and the receiving plate 111 to reduce the impact generated during the descent of the receiving plate 111 and further improve the stability of the device. This buffer design can reduce the mechanical wear of the equipment.

[0085] Furthermore, in this embodiment, the receiving plate assembly 110 includes: a first slide rail 115, which is vertically arranged; a first mounting plate 116, the receiving plate 111 is connected to the upper part of the first mounting plate 116, and the first mounting plate 116 is slidably connected to the first slide rail 115; the output end of the lifting drive unit 122 is drivenly connected to the first mounting plate 116 to drive the first mounting plate 116 to move along the first slide rail 115, thereby causing the receiving plate 111 to lift.

[0086] In this embodiment, the first slide rail 115 is vertically arranged, serving as a guide rail for the vertical movement of the receiving plate 111, ensuring precise up-and-down movement. The first mounting plate 116 not only supports the receiving plate 111 but also slides in conjunction with the first slide rail 115, ensuring that the receiving plate 111 smoothly slides up and down along the first slide rail 115 under the action of the lifting drive unit 122. The output end of the lifting drive unit 122 is directly connected to the first mounting plate 116. By driving the first mounting plate 116 to move along the first slide rail 115, efficient lifting and lowering of the receiving plate 111 is achieved, ensuring that the receiving plate 111 is at the same height as the feeding position or the pushing part 211, thus realizing smooth pipe connection or pushing action. In this embodiment, the output end of the lifting drive unit 122 is drivenly connected to the first mounting plate 116, while the non-output end (cylinder body part) is fixed to the base 113. In this way, the lifting drive unit 122 can precisely control the lifting and lowering of the first mounting plate 116, achieving a smooth transition between receiving and feeding functions. In alternative embodiments, the first mounting plate 116 can be raised and lowered using other types of drive units, such as hydraulic cylinders or electric actuators, to achieve the same functional effect, but may differ in response speed and ease of maintenance. Even in the most basic implementation, as long as the receiving plate 111 can be raised and lowered smoothly to receive the tubing, the production process can be significantly improved, the failure rate reduced, and the overall production line performance enhanced.

[0087] Furthermore, in this embodiment, the receiving plate assembly 110 includes: a second slide rail 117, which is arranged along a first horizontal direction and is connected to the upper part of the first mounting plate 116, and the receiving plate 111 is slidably connected to the second slide rail 117; and a second mounting plate 118, on which a plurality of receiving plates 111 are mounted, and the second mounting plate 118 is slidably connected to the second slide rail 117.

[0088] Preferably, the second mounting plate 118 is provided with a rack 123, and the output end of the first horizontal drive unit 121 is provided with a gear 124. The gear 124 is engaged with a plurality of racks and pinions, and the rotation of the gear 124 can drive the receiving plate 111 to move in the horizontal direction.

[0089] In this embodiment, the structure of the receiving plate assembly 110 is further optimized. The efficient movement and positioning of the receiving plate 111 are achieved through the combination of the second slide rail 117 and the second mounting plate 118. Multiple receiving plates 111 are spaced apart on the second mounting plate 118, enabling synchronous movement of the multiple receiving plates 111. Specifically, the second slide rail 117 is arranged along a first horizontal direction to ensure the receiving plates 111 remain stable during sliding. The second mounting plate 118, serving as the carrier for the multiple receiving plates 111, slides along the second slide rail 117, allowing the receiving plates 111 to move left and right, precisely aligning to the unloading position. Specifically, the receiving plate 111 moves to the left to receive four pipe sections, and then moves to the right to receive four more pipe sections, achieving a four-to-eight material distribution function.

[0090] Furthermore, in this embodiment, the feeding mechanism further includes: a third slide rail 114, which is arranged along the axial direction of the tube; the receiving plate assembly 110 further includes a base 113, with the receiving plate 111 connected to the upper part of the base 113; the base 113 is slidably connected to the third slide rail 114; at least a portion of the output end of the pushing drive assembly 220 is connected to the base 113 to drive the base 113 to slide along the tube axial direction on the third slide rail 114 to the bending position.

[0091] In this embodiment, to enhance the functionality and flexibility of the feeding mechanism, a third slide rail 114 is introduced, which is arranged along the axial direction of the tube material to support the precise positioning of the receiving plate assembly 110. The receiving plate assembly 110 is equipped with a base 113 as its supporting carrier, and the receiving plate 111 is firmly connected to the upper area of ​​the base 113. A sliding connection is established between the base 113 and the third slide rail 114 to ensure the smooth sliding of the receiving plate 111 along the axial direction of the tube material. The push drive assembly 220, as the drive core, has its output end connected to the base 113, which can precisely control the base 113 and the receiving plate 111 on it to slide along the third slide rail 114 to the designated bending position, realizing an integrated movement process of the tube material from the receiving position to the bending position. By precisely controlling the tube material movement distance, production efficiency is significantly improved, the scrap rate caused by tube material position deviation is reduced, the burden on operators is reduced, and the overall automation level of the equipment is enhanced. In the most basic design, even without the pusher drive assembly 220, the base 113 can still move manually on the third slide rail 114. However, this sacrifices the advantages of automation, increases manual operation, and thus affects production rhythm and accuracy. Nevertheless, this basic design still enables directional movement of the tube material and is suitable for scenarios where production speed requirements are not high.

[0092] Further, in this embodiment, the pusher drive assembly 220 includes: a second horizontal drive unit 221, the output end of which is connected to the receiving plate assembly 110 to drive the receiving plate assembly 110 to move along the tube axial direction to the bending position; and a third horizontal drive unit 222, the non-output end of which is connected to the output end of the second horizontal drive unit 221, and the output end of which is connected to the pusher assembly 210 to drive the pusher part 211 of the pusher assembly 210 to move along the tube axial direction to push the tube on the receiving plate 111 located at the bending position, thereby completing the feeding.

[0093] In this embodiment, the structural design of the pusher drive assembly 220 significantly optimizes the feeding process. The function of the second horizontal drive unit 221 is to push the receiving plate assembly 110 along the tube axis to the predetermined bending position, ensuring accurate alignment of the tube. Subsequently, the third horizontal drive unit 222 continues to operate, with its non-output end connected to the output end of the second horizontal drive unit 221, and its output end connected to the pushing part 211 of the pusher assembly 210, thereby completing the task of moving the tube from the receiving plate 111 to the bending station. This dual-drive configuration not only achieves precise positioning of the tube, but also effectively avoids deviation or jamming of the tube during the pushing process through the smooth movement of the pushing part 211 of the pusher assembly 210 along the tube axis, ensuring the continuity and efficiency of the production process. In an alternative embodiment, the second horizontal drive unit 221 and the third horizontal drive unit 222 can be implemented using other types of drive devices, such as cylinders or hydraulic cylinders, as long as accurate pushing and positioning of the tubing can be achieved. This adjustment provides more options for structural design and also has a direct impact on equipment maintenance and cost control. Preferably, the third horizontal drive unit 222 is a dual-axis cylinder.

[0094] The working process of the feeding mechanism for the integrated bending sleeve machine provided by this utility model is as follows:

[0095] First, such as Figure 4 As shown, the lifting drive unit 122 is activated, raising the receiving hole 1111 to the same height as the feeding position; then the first horizontal drive unit 121 drives the receiving hole 1111 to move to the left, catching four tubes of material; then the first horizontal drive unit 121 drives the receiving hole 1111 to move to the right, catching four more tubes of material; then the first horizontal drive unit 121 and the lifting drive unit 122 cooperate to lower the receiving hole 111 horizontally until it is aligned with the pushing part 211, as shown. Figure 5 As shown;

[0096] The second horizontal drive unit 221 drives the receiving plate assembly 110 to move along the tube axis to the bending position, such as Figure 6As shown; the third horizontal drive unit 222 drives the pushing part 211 of the pushing assembly 210 to move along the tube axis, pushing the tube material on the receiving plate 111 located at the bending position, thus completing the feeding, as shown. Figure 7 As shown.

[0097] In this series of actions, the cooperation between the pusher plate 212 and the elastic element 213 ensures that even with slight fluctuations in the tube length, the pusher assembly 210 can independently fine-tune its stroke, avoiding linkage interference. The guide shaft 215 provides additional support and guidance, ensuring smooth sliding of the pusher 211 during the pushing process, improving feeding accuracy and reliability. Furthermore, the sliding connection between the first through hole of the guide plate 112 and the pusher 211, along with the use of the buffer 214, effectively reduces the impact between the pusher plate 212 and the guide plate 112, further enhancing the smoothness and durability of the mechanism's operation, ensuring the continuity and efficiency of the bending and sleeve integrated machine during material distribution and feeding. The entire process embodies comprehensive optimization and innovation of the material distribution and feeding mechanism, solving key problems of material jamming and linkage interference in traditional mechanisms, and significantly improving the stability and production efficiency of the production line.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
