The expanding pipe process aims to transform a thin pipe into a thicker pipe through specific technical means. When dealing with the expanding pipe requirements of pipes with different specifications, it is necessary to rely on the coordinated operation of professional expanding pipe equipment, mandrels, and heating devices to ensure the precise local diameter expansion of the thin pipe in various devices. Given the increasing annual market share of electric vehicles, it is particularly important to perform expanding pipe treatment on the local pipe structure of the electric vehicle frame during the manufacturing process.

Specific embodiments
[0021] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.
[0022] The pipe expanding device for the production of an electric vehicle frame according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
[0023] As Figure 1-Figure 4 shown, the pipe expanding device for the production of an electric vehicle frame according to an embodiment of the present invention may include a frame 10 and a pipe expanding component 20. A first seat body 11 and a second seat body 12 are arranged side by side on the frame 10. Among them, a clamping component 70 is provided on the first seat body 11, and a through hole 121 is horizontally penetrated through the second seat body 12.
[0024] It should be noted that the clamping component 70 described in this embodiment is used to clamp and fix the pipe 90, so that the pipe 9 becomes stable during the pipe expanding operation. The clamping component 70 can be a lathe center rest, a mechanical gripper, etc. The clamping component 70 is a prior art and will not be elaborated here.
[0025] The pipe expanding component 20 is provided on the second seat body 12 through a cylinder 60. The pipe expanding component 20 may include a multi-stage pipe expanding part 40 and a driving component 30. Among them, the multi-stage pipe expanding part 40 is movably penetrated through the through hole 121. One end of the multi-stage pipe expanding part 40 is a planar structure, and the other end is a frustum-shaped structure. The multi-stage pipe expanding part 40 is formed by sequentially nesting a plurality of sleeves 41. Among them, the lengths of the plurality of sleeves 41 decrease sequentially from inside to outside. A plurality of U-shaped clamps 411 are circumferentially provided at one end of the sleeve 41.
[0026] It can be understood that the provided through hole 121 can limit the multi-stage expanding pipe fitting 40, thereby ensuring the stability of the movement of the multi-stage expanding pipe fitting 40. At the same time, the outer sleeve 41 can limit the inner sleeve 41, thereby enabling the stable performance during pipe expanding operations of different sizes.
[0027] The driving member 30 is arranged between the cylinder 60 and the multi-stage expanding pipe fitting 40. The driving member 30 may include an adjusting member 32 and multiple radial plates 31. Among them, the multiple radial plates 31 are circumferentially distributed. The radial plates 31 are slidably penetrated through the corresponding U-shaped clamps 411 by the adjusting member 32, and the radial plates 31 are slidably abutted against the planar end of the multi-stage expanding pipe fitting 40. The adjusting member 32 may include a connecting shaft 321 and a turntable 322. Among them, both ends of the connecting shaft 321 are respectively connected to the output end of the cylinder 60 and the turntable 322. Both ends of the turntable 322 are respectively connected to the motor 50 and the multi-stage expanding pipe fitting 40. The motor 50 is embedded in the groove 3211 on one side of the connecting shaft 321. The rotating shaft, the turntable 322, and the multi-stage expanding pipe fitting 40 are coaxially arranged. Multiple arc-shaped chutes 3221 are circumferentially formed on one side of the turntable 322. A slider 311 is provided on one side of the radial plate 31. Among them, the slider 311 is slidably arranged in the corresponding arc-shaped chute 3221. Both sides of the radial plate 31 are slidably adhered to the turntable 322 and the multi-stage expanding pipe fitting 40 respectively. The diameter of the turntable 322 is smaller than the diameter of the innermost sleeve 41
[0028] It should be noted that the radial plate 31 described in this embodiment can move along the radius of the turntable 322. When the number of sleeves 41 needs to be flexibly increased or decreased as required, only by controlling the radial plate 31 to move correspondingly along the radius of the turntable 322, during the process, the radial plate 31 can sequentially penetrate through the corresponding number of U-shaped clamps 411 and be in contact with the corresponding number of sleeves 41, and effectively push these sleeves 41 towards the direction of the first seat body 11 to perform pipe expanding operations of different sizes.
[0029] It should be noted that the adjusting member 32 described in this embodiment can control the synchronous movement of the multiple radial plates 31, enabling the multiple radial plates 31 to move synchronously towards the center or the outside of the turntable 322, enhancing the coordination and efficiency of the operation.
[0030] It should be noted that the arc-shaped chute 3221 described in this embodiment has a gradually increasing distance from the starting point to the end point to the center of the turntable 322. This design enables the turntable 322 to drive the multiple radial plates 31 to perform an orderly displacement along the radius of the turntable 322 during rotation, ensuring the smooth progress and precise control of the pipe expanding operation.
[0031] Specifically, during the actual process of expanding the pipe 90, the relevant personnel first determine the required number of sleeves 41 according to the need, and then fix the pipe 90 on the first seat body 11 through the clamping member 70.
[0032] Then, the relevant personnel control the rotation of the turntable 322 through the motor 50, so that multiple radial plates 31 are displaced orderly along the radial direction of the turntable 322, enabling the radial plates 31 to penetrate through the corresponding number of U-shaped clamps 411 and fit with the corresponding number of sleeves 41. Then, the adjusting member 32 is driven to move by the cylinder 60. After the adjusting member 32 moves, it can effectively push these sleeves 41 that are in contact with the radial plates 31 to move towards the direction of the first seat body 11 to perform pipe expanding operations of different sizes.
[0033] After the pipe expanding is completed, the relevant personnel control the adjusting member 32 to move in the reverse direction and reset through the cylinder 60, so that the corresponding sleeves 41 that enter the inner side of the pipe 90 can move and reset.
[0034] Further, as Figure 2 and Figure 3 shown, a plurality of limiting tracks 80 are provided at the end of the innermost sleeve 41, and the other side of the radial plate 31 is slidably arranged in the corresponding limiting tracks 80.
[0035] It can be understood that the provided limiting tracks 80 can further limit the radial plate 31, enabling the radial plate 31 to move stably under the rotation adjustment of the turntable 322.
[0036] In summary, for the pipe expanding device for the production of electric vehicle frames in the embodiment of the present utility model, the adjusting member can adjust multiple radial plates to perform corresponding expansion or retraction, enabling the multiple radial plates to fit with the corresponding number of sleeves, so that the number of sleeves can be flexibly increased or decreased as needed, and then the corresponding number of sleeves can be driven by the cylinder to perform pipe expanding operations of different sizes.
