Description

Technical Field

[0001] This utility model relates to the field of metal workpiece processing technology, and in particular to a novel fully automatic continuous tube shrinking machine. Background Technology

[0002] Currently, driven by the era of industrial automation, all industries are striving to improve their automation equipment levels, which in turn determine a company's competitiveness. Many fields utilize hollow metal tubular products. These products are typically pre-formed into initial tube blanks, which are then shrunk using a tube shrinking machine and shrinking molds to obtain the finished tube blank. However, in most cases, this tube shrinking process cannot be completed in one step and may require two or more steps to achieve the final shape. Traditionally, one step is completed on a single tube shrinking machine, and then the semi-finished tube blank is manually transferred to the next machine for the next step. This not only requires multiple independent tube shrinking machines but also necessitates dedicated personnel for material transfer between them, resulting in high equipment and labor costs, low efficiency, large space requirements, and low profitability. Utility Model Content

[0003] To address the technical problems existing in the prior art, the purpose of this utility model is to provide a new type of fully automatic continuous tube shrinking machine that eliminates the need for manual material transfer between workstations and allows for efficient and rapid automatic material loading and unloading between workstations.

[0004] The objective of this utility model is achieved through the following technical solution: A novel fully automatic continuous tube shrinking machine includes at least one tube shrinking mechanism and a material conveying mechanism; each of the tube shrinking mechanisms is arranged sequentially according to the station order to form a continuous series of tube shrinking stations; the material conveying mechanism is located below the tube shrinking mechanisms, and the material conveying mechanism connects the feeding station, each tube shrinking station, and the discharging station in series; the material conveying mechanism includes at least one set of supports and their support driving devices, and a transmission component and its transmission driving device; each set of supports is located below each tube shrinking mechanism, and the supports lift the tube blank to the clamping height of the tube shrinking mechanism through their corresponding support driving devices; each set of supports is matched with a set of transmission components, and the transmission components implement lever movement through their corresponding transmission driving devices to realize the tube blank being conveyed between adjacent sets of supports by its own gravity.

[0005] Compared with the prior art, the present invention has at least the following beneficial effects:

[0006] 1. This utility model features multiple independent tube-shrinking mechanism units. The number of units can be increased or decreased according to product requirements. Each unit is modularly designed and capable of independent operation. The corresponding material conveying mechanism uses a modular connection that can be modified according to changes in the equipment units. No manual material transfer between workstations is required. Materials can be automatically and efficiently placed and retrieved between workstations with precise positioning, achieving uninterrupted and smooth production, significantly improving production efficiency, and reducing production and labor costs.

[0007] 2. This utility model has a simple structure, reasonable design, high efficiency, low cost, and high degree of automation, making it suitable for market promotion.

[0008] Specifically, each set of conductive components and its conductive drive device includes a front guide plate, a front support seat, and a front conductive drive device correspondingly disposed in front of the support. The front guide plate includes a front input end and a front output end. The front input end is suspended or corresponds to the previous set of conductive components. The front output end is correspondingly connected to the support. The front guide plate is connected to the front support seat and swings with the front support seat as a lever fulcrum. The front conductive drive device is driven to the front output end to control the lever movement of the front guide plate, thereby driving the tube blank on the front guide plate to roll to the support.

[0009] Furthermore, the upper surface of the guide plate is provided with multiple first ribs extending axially. The height of the first ribs near the edge is higher than that of the first ribs near the center, so that the multiple first ribs form a concave shape on the guide plate. The concave shape is used to match the shape of the tube blank placed on it, which is larger in the middle and smaller on both sides, thereby limiting its position.

[0010] Furthermore, the first rib at the front input end of the guide plate protrudes to form a barb, effectively preventing the tube blank on it from flowing back and rolling away from the front input end.

[0011] Specifically, each set of conductive components and its conductive drive device also includes a rear guide plate, a rear support seat, and a rear conductive drive device correspondingly disposed behind the support. The rear guide plate includes a rear input end and a rear output end. The rear input end is connected to the support, and the rear output end is suspended or corresponds to the front input end of the front guide plate of the next set of conductive components. The rear guide plate is connected to the rear support seat and swings with the rear support seat as a lever fulcrum. The rear conductive drive device is driven to the rear input end to control the lever movement of the rear guide plate, thereby driving the tube blank on the rear guide plate to roll away from the support.

[0012] Furthermore, the upper surface of the rear guide plate is provided with multiple second ribs extending axially. The height of the second ribs near the edge is higher than that of the second ribs near the center, so that the multiple second ribs form a concave shape on the rear guide plate. The concave shape is used to match the shape of the tube blank placed on it, which is larger in the middle and smaller on both sides, thereby limiting its position.

[0013] Furthermore, it also includes a frame; each tube shrinking mechanism includes a clamp and its clamping drive device, and a tube shrinking mold and its tube shrinking drive device; the clamp consists of two horizontally facing clamping arms, which are arranged one in front of the other on the frame according to the station sequence. The opposing surfaces of the two clamping arms are their respective clamping surfaces, which are concave and semi-circular. When the two clamping arms are joined, their clamping surfaces together form a circular through groove for correspondingly clamping the expanded part of the tube blank; the clamping drive device connects to the two clamping arms and drives them to move towards each other, and the clamping drive device is embedded in the frame. The clamps arranged in front and behind the tube shrinking mechanism are staggered from the lifting and conveying support, improving efficiency and space utilization. Moreover, as the clamps are arranged in front and behind, their clamping drive devices are set to be embedded, which effectively simplifies the external contour of the equipment and effectively reduces the distance between stations, not only reducing space waste but also shortening the tube shrinking process and improving efficiency.

[0014] Specifically, each set of supports includes two horizontally arranged blocks with concave upper surfaces forming a U-shape. The two blocks in each set are positioned one on the left and one on the right below the clamps of the tube shrinking mechanism, according to the station sequence. Each set of two blocks corresponds to the two shrinking sections of the tube blank, thus stably supporting the tube blank.

[0015] Furthermore, the material conveying mechanism also includes at least one disengagement drive device, with one disengagement drive device corresponding to each set of supports; the disengagement drive device is located between each set of two supports, and the telescopic shaft of the disengagement drive device faces upwards, for pushing the tube blank that has completed tube shrinkage out of the support.

[0016] Furthermore, the support has a pair of vertically erected telescopic rods on both outer sides, the ends of which are fixedly connected to the support block to assist the support in vertically raising and lowering without deviation. Attached Figure Description

Detailed Implementation

[0023] To facilitate understanding of this utility model, the technical solutions and advantages of the utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Any mechanisms or methods not elaborated in this utility model can be referred to in the prior art. The specific structures and features of this utility model are illustrated below by way of example and should not constitute any limitation on this utility model. Furthermore, any technical feature mentioned below (including implicit or disclosed features), as well as any technical feature directly shown or implied in the figures, can be arbitrarily combined or deleted among these technical features to form more other embodiments that may not be directly or indirectly mentioned in this utility model. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0024] like Figure 1-5 As shown, the fully automatic continuous tube shrinking machine of this embodiment includes a frame 10, multiple tube shrinking mechanisms, and a material conveying mechanism. Multiple independent tube shrinking mechanisms are arranged in the forming sequence on a single fully automatic continuous tube shrinking machine. Preferably, three tube shrinking mechanisms are provided in this embodiment. The tube shrinking mechanisms are mounted on the frame 10, with each tube shrinking mechanism corresponding to one station, forming multiple continuous tube shrinking stations. A material conveying mechanism is provided between each station, positioned below the tube shrinking mechanisms, connecting the feeding station, each tube shrinking station, and the discharging station in series to form an automated continuous tube shrinking production line.

[0025] Specifically, each tube shrinking mechanism includes a clamp 21 and its clamping drive device 23, and a tube shrinking mold 26 and its tube shrinking drive device 28. The clamp 21 consists of two horizontally facing clamping arms, with each set of two clamping arms arranged one in front of the other on the frame 10 according to the station sequence. The opposing surfaces of the two clamping arms are their respective clamping surfaces, which are concave and semi-circular. When the two clamping arms are joined, their clamping surfaces form a circular through groove, used to clamp the expanded portion of the tube blank G to be shrunk. The tube blank G to be shrunk includes an expanded portion in the middle and shrinking portions on both sides. The clamping drive device 23 consists of two hydraulic cylinders corresponding to the two clamping arms, driving the two clamping arms to move towards each other. The clamping drive device 23 is embedded in the frame 10. The clamping drive device 23 is connected to the frame 10 in a built-in manner, effectively reducing the distance between stations, not only reducing space waste but also shortening the tube shrinking process and improving efficiency. The telescopic shaft of the clamp drive device 23 is housed within the clamp drive device 23, and the end of the telescopic shaft is connected to the clamp 21.

[0026] Two sets of tube-shrinking dies 26, arranged in a mirror configuration, are mounted on the frame 10 via die guide rails to perform tube-shrinking processing on both sides of the tube blank G. The tube-shrinking drive device 28 consists of two hydraulic cylinders corresponding to the two sets of tube-shrinking dies 26, respectively. These cylinders are mounted on the frame 10 and located on the outer sides of the two sets of tube-shrinking dies 26, respectively, to drive the two sets of tube-shrinking dies 26 to move towards each other for tube shrinking or to move away from each other for retraction. The specific structure and connection relationship of the tube-shrinking dies 26 and their drive device 28 have been disclosed in the applicant's published patent application and will not be repeated here.

[0027] The material conveying mechanism is located below the fixture 21. The material conveying mechanism is used to feed the tube blank G into the fixture 21 and to transfer the tube blank G between adjacent tube shrinking mechanisms.

[0028] The material conveying mechanism includes multiple sets of supports 41 and their support drive devices 42, multiple sets of transmission components and their transmission drive devices, and multiple disengagement drive devices 49. The number of supports 41, transmission components, and disengagement drive devices 49 is the same as the number of sets of the tube shrinking mechanism. In this embodiment, preferably, the material conveying mechanism includes three sets of supports 41, three sets of transmission components, and three disengagement drive devices 49.

[0029] Each set of support brackets 41 includes two horizontally arranged support blocks with concave upper surfaces forming a U-shape. Each set of two support blocks is positioned one on the left and one on the right below the clamping fixture 21 of the tube shrinking mechanism, according to the workstation sequence, to lift the tube blank G to the clamping height of the fixture 21 and to retrieve the tube blank G after shrinking. Specifically, each set of two support blocks corresponds to the two shrunken portions of the tube blank G, ensuring stable lifting of the tube blank G. The support bracket drive device 42 is a hydraulic cylinder, connected below each support block, used to raise the support bracket 41.

[0030] Each set of transmission components and its transmission drive device includes a front guide plate 43, a front support seat 44, a front transmission drive device 45, a rear guide plate 46, a rear support seat 47, and a rear transmission drive device 48. Each set of transmission components corresponds to a set of supports 41. According to the workstation sequence direction, the front guide plate 43, the front support seat 44, and the front transmission drive device 45 are arranged in front of their corresponding supports 41, and the rear guide plate 46, the rear support seat 47, and the rear transmission drive device 48 are arranged behind their corresponding supports 41.

[0031] Specifically, the front guide plate 43 is a long strip of plate with multiple axially extending first ribs 431 on its upper surface. The height of the first ribs 431 near the edge is higher than that of the first ribs 431 near the center, so that the multiple first ribs 431 form a concave shape on the front guide plate 43. The concave shape is used to match the shape of the tube blank G placed on it, which is larger in the middle and smaller on both sides, thereby limiting its position. The two ends of the front guide plate 43 are the front input end 432 and the front output end 433, respectively. The front input end 432 is suspended or corresponds to the rear output end 463 of the rear guide plate 46 of the previous set of transmission components. The front output end 433 is connected to the support 41. The front guide plate 43 is used to transport the tube blank G to the support 41. A front support seat 44 is provided below the front guide plate 43, and the front guide plate 43 swings with the front support seat 44 as the lever fulcrum. The front output end 433 of the front guide plate 43 is connected to the front transmission drive device 45, which is a hydraulic cylinder. It is used to drive the front output end 433 to lift and lower to control the lever movement of the front guide plate 43, thereby driving the tube blank G on the front guide plate 43 to roll to the support 41.

[0032] In this preferred embodiment, the first rib 431 at the front input end 432 of the front guide plate 43 protrudes to form a barb, which effectively prevents the tube blank G on it from flowing back and rolling away from the front input end 432.

[0033] The rear guide plate 46 is a long strip of plate with multiple axially extending second ribs 462 on its upper surface. The height of the second ribs 462 near the edge is higher than that of the second ribs 462 near the center, so that the multiple second ribs 462 form a concave shape on the rear guide plate 46. The concave shape is used to match the shape of the tube blank G placed on it, which is larger in the middle and smaller on both sides, thereby limiting its position. The two ends of the rear guide plate 46 are the rear input end 462 and the rear output end 463, respectively. The rear input end 462 is connected to the support 41, and the rear output end 463 is suspended or corresponds to the front input end 432 of the front guide plate 43 of the next set of transmission components. The rear guide plate 46 is used to transport the tube blank G away from the support 41. A rear support seat 47 is provided below the rear guide plate 46, and the rear guide plate 46 swings with the rear support seat 47 as the lever fulcrum. The rear input end 462 of the rear guide plate 46 is connected to the rear transmission drive device 48, which is a hydraulic cylinder. It is used to drive the rear input end 462 to lift and lower to control the lever movement of the rear guide plate 46, thereby driving the tube blank G on the rear guide plate 46 to roll away from the support 41.

[0034] Each set of disengagement drive devices 49 corresponds to each set of support 41. The disengagement drive device 49 is a hydraulic cylinder, which is set between the two support blocks in each set. The telescopic shaft of the disengagement drive device 49 faces upward and is used to push the tube blank G that has completed tube shrinkage out of the support 41 so that it rolls down to the rear guide plate 46.

[0035] In this preferred embodiment, a pair of vertically erected telescopic rods 50 are provided on both outer sides of the support 41. The ends of the telescopic rods 50 are fixedly connected to the support block to assist the support 41 in vertical lifting and lowering without deviation.

[0036] Working principle:

[0037] The fully automatic continuous tube shrinking machine in this embodiment consists of a first group of tube shrinking mechanisms, a second group of tube shrinking mechanisms, and a third group of tube shrinking mechanisms in sequence. The front input end 432 of the guide plate 43 corresponding to the material conveying mechanism of the first tube shrinking mechanism is suspended, and this front input end 432 corresponds to the loading station. The tube blank G to be shrunk is placed on this front input end 432. Through the descending front transmission drive device 45, the guide plate 43 tilts downwards towards its front output end 433 and connects to the support 41 below the first group of tube shrinking mechanisms. The tube blank G rolls from the front input end 432 of the guide plate 43 to the front output end 433 under its own weight and falls into the support 41 that connects to it. The two shrunken parts of the tube blank G fall into the upper concave surfaces of the two support blocks, and the expanded parts of the tube blank G are engaged between the two support blocks. The support drive device 42 drives the support 41 to rise to the clamping height of the clamp 21 of the first tube shrinking mechanism. The clamp 21 clamps the tube blank G, the support 41 retracts, and the first tube shrinking mechanism performs the first tube shrinking operation on the tube blank G.

[0038] After completing the first tube shrinking process, the support 41 retrieves the tube blank G. Specifically, the support 41 rises to support the tube blank G, and the clamp 21 retracts. The support drive device 42 drives the support 41 to descend to a suitable height, and the rear transmission drive device 48 drives the rear input end 462 of the rear guide plate 46 to engage with the support 41, and the rear guide plate 46 is tilted downward toward its rear output end 463. Then, the tube blank G, which is stuck in the support 41, is pushed upward by the telescopic axis of the disengaged drive device 49. The tube blank G rolls down to the rear guide plate 46 and rolls from the rear input end 462 of the rear guide plate 46 to the rear output end 463 by its own gravity. The rear output end 463 connects to the front input end 432 of the front guide plate 43 of the next set of transmission components. The tube blank G rolls into the next set of transmission components for the second tube shrinking process, and similarly enters the third tube shrinking process. Finally, it rolls out from the rear output end 463 of the rear guide plate 46 of the transmission component corresponding to the third set of tube shrinking mechanism. The rear output end 463 is suspended and corresponds to the discharge station. At this time, the tube blank G has been formed after three tube shrinking processes.

[0039] Compared with existing technologies, the fully automatic continuous tube shrinking machine in this embodiment is equipped with multiple independent tube shrinking mechanism units. The number of units can be increased or decreased according to product requirements. Each unit is modularly designed and has independent operating capabilities. The corresponding material conveying mechanism uses a modular connection and can be modified according to changes in equipment units. There is no need for manual material transfer between workstations; materials can be automatically and efficiently placed and retrieved between workstations with precise positioning, achieving uninterrupted and smooth production, significantly improving production efficiency, and reducing production and labor costs.

[0040] Furthermore, the clamps at the front and rear of the tube shrinking mechanism are staggered with the lifting and conveying support, improving efficiency and space utilization. Moreover, the clamp drive devices for the front and rear clamps are embedded, effectively simplifying the external contour of the equipment and reducing the distance between workstations. This not only reduces space waste but also shortens the tube shrinking process, thus improving efficiency.

[0041] The above embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. For those skilled in the art, it will be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
