[0057] See also Figures 1 to 4 The embodiment of the present invention provides a multi-layer tube expansion and expanding device, comprising a feeding device, a multi-layer tube expansion device 3, a material transfer device 4, a tube orifice shaping device 5 and a material return device 6 connected in sequence;
[0058] The loading device is used to load the tooling plate 9 carrying the two devices 10;
[0059] The feeding device can be switchably connected with the multi-layer tube expansion station in the multi-layer tube expansion device 3, and is used to drive the tooling plate 9 to move to the corresponding tube expansion station to perform tube expansion processing of the two devices 10;
[0060] The material transfer device 4 is switchably connected to the multi-layer tube expansion station and is used to receive the tooling plate 9 output from the multi-layer tube expansion station and transfer it to the tube orifice shaping device 5;
[0061] The nozzle shaping device 5 is used to shape the two devices 10 on the tooling plate 9;
[0062] The material return device 6 is used to receive the tooling plate 9 output by the pipe opening shaping device 5 to obtain two devices 10 after the pipe opening is expanded.
[0063] In this embodiment, the multi-layer expansion device 3 is the core optimization part of the equipment, which is composed of multi-layer expansion stations, each of which is equipped with an independent expansion mechanism, which can independently expand the two devices 10 on the tooling plate 9. The multi-layer expansion device 3 can solve the problem of the processing time difference between the expansion process and the expansion process, ensure the efficient operation of each process, and improve production efficiency. Specifically, the processing time required for the expansion process is greater than the processing time of the expansion process, so multiple expansion devices are superimposed to form a multi-layer expansion device 3. The multi-layer expansion device 3 can simultaneously perform expansion processing of multiple groups of two devices 10, thereby ensuring that the subsequent nozzle shaping device 5 can maintain efficient operation, so as to solve the problem of frequent standby waiting of the nozzle shaping device 5.
[0064] In this embodiment, the feeding device, the material transfer device 4, the pipe mouth shaping device 5 and the material return device 6 are all automatically controlled to ensure the smoothness and accuracy of the entire expansion and expansion process. The feeding device can automatically feed the tooling plate 9 loaded with the two devices 10, reduce manual operations, and improve production safety. The material transfer device 4 ensures the accurate transfer of the tooling plate 9 from the multi-layer expansion device 3 to the pipe mouth shaping device 5 through a precise positioning system, thereby avoiding operational errors. The pipe mouth shaping device 5 is equipped with an expansion mechanism, which can perform fine expansion processing on the pipe mouths of the two devices 10 to ensure that the size and shape of the pipe mouths of the two devices 10 meet the design requirements. The material return device 6 returns the tooling plate 9 that has completed expansion and expansion to the next link of the production line, or stores it for subsequent assembly or inspection.
[0065] The feeding device is described in detail below.
[0066] In one embodiment, the loading device includes a horizontal loading device 1 and a lifting and feeding device 2 connected to each other; the horizontal loading device 1 is used to load the tooling plate 9 loaded with two devices 10, and can drive the tooling plate 9 to be transported horizontally to the lifting and feeding device 2; the lifting and feeding device 2 can be raised and lowered and can be switchably connected to the multi-layer expansion station of the multi-layer expansion device 3, and is used to drive the tooling plate 9 to perform lifting and lowering movements and transport the corresponding expansion station.
[0067] In this embodiment, in order to adapt to the design of the multi-layer expansion device 3, the loading device needs to have the function of driving the tooling plate 9 to be transported to the different layers of the expansion station of the multi-layer expansion device 3, so the loading position of the loading device needs to be designed. Specifically, the loading device includes a horizontal loading device 1 and a lifting and feeding device 2 connected to each other. The horizontal loading device 1 is used to drive the tooling plate 9 to be transported and loaded in the horizontal direction. At this time, the tooling plate 9 will not move in height, which is more convenient for loading; then the lifting and feeding device 2 receives the tooling plate 9 transported by the horizontal loading device 1, and then drives the tooling plate 9 to move up and down in the height direction, so that the tooling plate 9 can correspond to the different layers of the multi-layer expansion device 3, so as to realize the tooling plate 9 being fed to the expansion station of different layers for the expansion process of the two devices 10.
[0068] The multi-layer tube expansion device 3 is described in detail below.
[0069] In a specific embodiment, the multi-layer expansion device 3 includes an upper expansion device 31 and a lower expansion device 32 which are stacked up and down; the expansion position of the upper expansion device 31 corresponds to the upper limit position of the lifting and feeding device 2, and the expansion position of the lower expansion device 32 corresponds to the lower limit position of the lifting and feeding device 2.
[0070] In this specific embodiment, the number of layers of the multi-layer tube expansion device 3 is the number of superimposed tube expansion devices, and the specific number of layers can be set according to the specific implementation differences of the tube expansion process and the expansion process. For example, if the tube expansion process of the device takes about twice as long as the expansion process, two layers of tube expansion devices can be set, that is, an upper tube expansion device 31 and a lower tube expansion device 32 are set up in a stacked manner. The upper tube expansion device 31 and the lower tube expansion device 32 can perform tube expansion operations independently, thereby improving the tube expansion efficiency.
[0071] In this specific embodiment, the expansion station inlets of the upper expansion device 31 and the lower expansion device 32 respectively correspond to the upper and lower limit positions of the lifting and feeding device 2, thereby ensuring that the tooling plate 9 is accurately delivered to the designated expansion station, thereby ensuring the accuracy and reliability of the transfer of the tooling plate 9.
[0072] In some other embodiments, an additional layer of cooperative tube expansion device (not shown in the figure) can be added to the multi-layer tube expansion device 3, and the cooperative tube expansion device is also superimposed therein, and after the upper tube expansion device 31 and the lower tube expansion device 32 perform a part of the tube expansion work, the tooling plate 9 is returned to the lifting and feeding device 2, and the lifting and feeding device 2 transfers the tooling plate 9 to the tube expansion station of the cooperative tube expansion device for another part of the tube expansion work, so as to realize the cooperative work between different tube expansion stations, so as to adapt to the tube expansion requirements of two devices 10 of different sizes and shapes. Specifically, the cooperative tube expansion device can be arranged between the upper tube expansion device 31 and the lower tube expansion device 32.
[0073] The material transfer device 4 is described in detail below.
[0074] Combination Figure 6 As shown, in one embodiment, the material transfer device 4 can be raised and lowered; the expansion position of the upper expansion device 31 corresponds to the upper and lower limit positions of the material transfer device 4, and the expansion position of the lower expansion device 32 corresponds to the lower and upper limit positions of the lifting and feeding device 2.
[0075] In this embodiment, the structural principle of the material transfer device 4 can be the same as the structural principle of the lifting and feeding device 2. The material transfer device 4 performs lifting and lowering movements in the height direction and docks with the expansion stations of each layer in the multi-layer expansion device 3 in the height direction, thereby receiving the tooling plate 9 output from the expansion station (that is, the tooling plate 9 after the expansion process of the two devices 10 is completed).
[0076] In this embodiment, the expansion station outlets of the upper expansion device 31 and the lower expansion device 32 respectively correspond to the upper and lower limit positions of the material transfer device 4, thereby ensuring that the tooling plate 9 is accurately transferred from the expansion station to the material transfer device 4, thereby ensuring the accuracy and reliability of the transfer of the tooling plate 9.
[0077] In one embodiment, the multi-layer tube expansion and flaring device further comprises a return track device 7 (refer to Figure 3 and Figure 4 );One end of the return track device 7 is connected to the return device 6, and the other end of the return track device 7 is connected to the horizontal feeding device 1; the return track device 7 is used to drive the tooling plate 9 on the return device 6 to be transported to the horizontal feeding device 1.
[0078] In this embodiment, after the tooling plate 9 is transferred to the return device 6, the two devices 10 on the tooling plate 9 have completed the expansion and flaring processes, and the tooling plate 9 is driven from the return device 6 to return to the horizontal loading device 1 through the return track device 7. After the two devices 10 that have completed the expansion and flaring are removed from the tooling plate 9 on the horizontal loading device 1, new two devices 10 can be placed on the tooling plate 9, and then the processing of the new two devices 10 can be performed; this cycle is repeated, reducing the manual work of recycling the tooling plate 9 in the return device 6, improving the efficiency of automated production, and reducing operating costs.
[0079] Specifically, the return track device 7 can be arranged at the bottom of the horizontal loading device 1, the lifting and feeding device 2, the multi-layer expansion device 3, the material transfer device 4, the pipe mouth shaping device 5 and the return material device 6. The return track device 7 can adopt one of the belt conveyor structure, the rotating roller conveyor structure and the chain conveyor structure to realize the return transmission of the tooling plate 9.
[0080] In one embodiment, the horizontal loading device 1, the lifting and feeding device 2, the multi-layer expansion device 3, the material transfer device 4, the tube mouth shaping device 5 and the return device 6 are all provided with a carrying and conveying platform 8 for driving the tooling plate 9 to be transported in a horizontal direction; the lifting and feeding device 2 and the material transfer device 4 are provided with a lifting component 21, and the lifting component 21 is used to drive the corresponding carrying and conveying platform 8 to perform lifting and lowering movements.
[0081] In this embodiment, the horizontal feeding device 1 and the return device 6 can adopt the same structural principle. Figure 5 In the example of the horizontal loading device 1, the carrying and conveying platform 8 is located at the top of the horizontal loading device 1 to realize the carrying of the tooling plate 9. The carrying and conveying platform 8 can drive the tooling plate 9 to move in the horizontal direction, that is, drive the two devices 10 to move in the horizontal direction, so that the two devices 10 can be circulated in sequence according to the processing procedures. Among them, the tooling plate 9 needs to reach the height of different layers when circulating in the multi-layer expansion device 3. Therefore, it is necessary to set a lifting component 21 at the front and rear nodes of the multi-layer expansion device 3, that is, in the lifting and feeding device 2 and the material transfer device 4. The lifting component 21 drives the corresponding carrying and conveying platform 8 to perform lifting and lowering movements to realize the circulation of the tooling plate 9 in the multi-layer expansion device 3.
[0082] Specifically, the driving structure of the carrying conveyor platform 8 is one of a belt conveyor structure, a rotating roller conveyor structure and a chain conveyor structure, which can be selected according to specific needs; the driving structure of the lifting component 21 is one of a screw drive structure, a cylinder drive structure and a chain conveyor structure, which can be selected according to specific needs.
[0083] like Figure 7 As shown, an embodiment of the present invention further provides a tube expansion and expanding method, which is applied to the multi-layer tube expansion and expanding device as described above. The tube expansion and expanding method includes steps S701 to S706:
[0084] S701, loading the current tooling plate 9 loaded with two devices 10 onto the loading device and transporting it to the multi-layer tube expansion device 3;
[0085] S702, detecting the idle state of the multi-layer tube expansion station in the multi-layer tube expansion device 3 and determining the target tube expansion station;
[0086] S703, controlling the feeding device to dock with the target tube expansion station in the multi-layer tube expansion device 3, and driving the current tooling plate 9 to move to the target tube expansion station to perform tube expansion processing of the two devices 10;
[0087] S704, controlling the material transfer device 4 to dock with the target tube expansion station in the multi-layer tube expansion device 3, so as to receive the current tooling plate 9 sent from the target tube expansion station after the tube expansion process of the two devices 10, and transfer the current tooling plate 9 to the tube orifice shaping device 5;
[0088] S705, shaping the two devices 10 on the current tooling plate 9 by the nozzle shaping device 5;
[0089] S706, the tooling plate 9 outputted from the pipe opening shaping device 5 is received by the material return device 6 to obtain two devices 10 after the expansion and flaring.
[0090] In this embodiment, based on the processing control process of steps S701 to S706, multiple tube expansion devices are used to form a multi-layer tube expansion device 3 by stacking the tube expansion devices. The multi-layer tube expansion device 3 can simultaneously perform tube expansion processing of multiple groups of two devices 10, thereby ensuring that the subsequent tube mouth shaping device 5 can maintain efficient operation, so as to solve the problem of frequent standby waiting of the tube mouth shaping device 5. This has the advantage of improving production efficiency.
[0091] In one embodiment, if Figure 8 As shown, step S702 includes:
[0092] S801, detecting whether the tube expansion station of the upper tube expansion device 31 and the tube expansion station of the lower tube expansion device 32 are in an idle state, and entering corresponding steps in S802 to S804 according to the idle state;
[0093] S802, if none of them are in an idle state, the tube expansion station of the lower tube expansion device 32 is determined as the target tube expansion station;
[0094] S803, if only one of the tube expansion stations is in an idle state, the idle tube expansion station is determined as the target tube expansion station;
[0095] S804: If none of the expansion stations are in an idle state, wait until an idle expansion station appears and then confirm it as the target expansion station.
[0096] In this embodiment, based on the process of steps S801 to S804, a solution for automatic distribution and circulation of double expansion station production is implemented, so that the two expansion stations can perform uninterrupted and continuous expansion respectively, thereby maintaining efficient operation and solving the problem of frequent standby waiting of the tube mouth shaping device 5.
[0097] In one embodiment, if Fig. 9 As shown, step S703 includes:
[0098] S901, when the tube expansion station of the upper tube expansion device 31 is the target tube expansion station, the lifting and feeding device 2 is controlled to drive the current tooling plate 9 to move upward and reach the upper limit of the lifting and lowering, so as to achieve docking with the target tube expansion station and then drive the current tooling plate 9 to move to the target tube expansion station;
[0099] S902, when the expansion station of the lower expansion device 32 is the target expansion station, the lifting and feeding device 2 is controlled to drive the current tooling plate 9 to move downward and reach the lower limit of the lifting and lowering, so as to achieve docking with the target expansion station and then drive the current tooling plate 9 to move to the target expansion station.
[0100] In this embodiment, based on the process of steps S901 to S902, the advantage of lifting and feeding device 2 to drive tooling plate 9 to be accurately fed into the target tube expansion station is achieved.
[0101] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the method described above can refer to the corresponding process in the aforementioned device embodiment, and will not be repeated here.

Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
