The inner wall of the cross groove 232 is fixedly connected with a cross block 233, and each cross block 233 is fixedly connected with two slide plates 234 at the protrusion away from the center point, and the two slide plates 234 are fixedly connected to the inner wall of the cross groove 232 on the side away from each other, and the front side of the cross block 233 is fixedly connected to the rear side of the rear polygonal block 221, and the outer walls of two adjacent slide plates 234 are movably connected with I-shaped movable blocks 235, and the front side of the I-shaped movable blocks 235 near the center point is provided with an arc groove extending to the rear side, and the center position of the front side of the cross block 233 is provided with a mounting groove 236, and the inner wall of the mounting groove 236 is fixedly connected with a stepper motor 1 237, and the output end of the stepper motor 1 237 is fixedly connected to the rear end of the rear screw rod 1 222, and the I-shaped movable blocks 235 are movably connected to the outer walls of the two adjacent slide plates 234. The front side of the block 235 close to the center point is fixedly connected to the rear side of the rear arc plate 228, and the inner wall of the arc groove is fixedly connected to the side of the rear fixed block 227 away from the center point. The winding structure 3 includes a fixed column 31, and the front end of the fixed column 31 is provided with a circular array of fan-shaped through holes extending to the rear end. The center position of the front end of the fixed column 31 is provided with a circular movable hole three extending to the rear end. The inner wall of the circular movable hole three is movably connected to the outer wall of the connecting rod 21. The outer wall of the fixed column 31 is fixedly connected and wrapped with a tungsten alloy power spring 32. The outer wall of the tungsten alloy power spring 32 is provided with a polygonal winding shell 33. A rectangular through hole extending to the inside is provided on one side of the polygonal winding shell 33. The outer wall of the tungsten alloy power spring 32 is movably connected to the inner wall of the rectangular through hole.The outer wall of the tungsten alloy power spring 32 passes through the inner walls of the two guide holes 229 and wraps around the outer wall of the arc plate 228. The outer wall of the tungsten alloy power spring 32 away from the fixed column 31 is fixedly connected to the outer wall of the arc plate 228 with the guide hole 229. The end of the tungsten alloy power spring 32 away from the fixed column 31 is an inclined surface and fits the outer wall. The rear side of the polygonal winding shell 33 is fixedly connected to the front side of the rear polygonal block 221. The mold structure 5 includes an outer mold 51. The outer wall of the outer mold 51 is horizontally arrayed and fixedly connected with a plurality of casting tubes 52. The outer wall of the mounting tube 1 is horizontally arrayed with a plurality of circular movable holes 6 that penetrate into the interior. The outer wall of the casting tube 52 is fixedly connected to the inner wall of the circular movable hole 6.

[0033] By starting the stepper motor 237, the rear screw rod 222 starts to rotate, and drives the front screw rod 222 to rotate through the connecting rod 21. Since the slider 223 is threadedly connected to the screw rod 222, the slider 223 starts to move horizontally along the screw rod 222. This displacement causes the movable plate 224 to swing accordingly under the action of the hinge point. The swinging behavior of the movable plate 224 will push the telescopic rod 226 to telescope along the circular movable hole 1 of the mounting groove 225. As the telescopic rod 226 is extended and retracted, the fixed block 227 and the arc plate 228 connected thereto will expand outward or contract inward accordingly. Since the arc plate 228 is connected to the outer wall of the tungsten alloy power spring 32, when the arc plate 228 expands or contracts, it will stretch or compress the tungsten alloy power spring 32 accordingly. The spring 32 has good elasticity and resilience, and can provide sufficient supporting force when the arc plate 228 expands, and quickly return to its original state when the arc plate 228 contracts. This telescopic movement allows the internal space of the mold structure 5 to be flexibly adjusted to meet the casting requirements of stainless steel pipes of different sizes. When a stainless steel pipe of smaller thickness needs to be cast, the stepper motor 237 drives the screw rod 222 to move the slider 223 away from the center point, and the movable plate 224 swings outward, the telescopic rod 226 extends, and the fixed block 227 and the arc plate 228 expand outward, thereby stretching the tungsten alloy power spring 32. At this time, the internal space of the outer mold 51 becomes smaller to adapt to the casting of stainless steel pipes of smaller thickness. During the casting process, the casting tube 52 is used to inject molten stainless steel liquid into the outer mold 51 and the tungsten alloy power spring 32.

[0034] like Figure 8-9As shown, the tensile structure 4 includes a mounting platform 41, and mounting grooves 3 42 are provided on both sides of the left and right sides of the top front side of the mounting platform 41. A motor groove 1 is provided on the top of the mounting platform 41 near the front side of the right mounting groove 3 42, and a circular movable hole 4 is provided on the rear side of the inner wall of the motor groove 1, which penetrates into the right mounting groove 3 42. A rotating shaft 1 43 is movably connected to the inner wall of the circular movable hole 43, and a stepper motor 2 44 is fixedly connected to the front end of the rotating shaft 1 43. The stepper motor 2 44 is fixedly connected to the inner wall of the motor groove 1, and a screw rod 2 45 is fixedly connected to the rear end of the rotating shaft 1 43. The rear end of the screw rod 2 45 is rotatably connected to the inner wall of the right mounting groove 3 42, and a slider 2 46 is threadedly connected to the outer wall of the screw rod 2 45. The top of the slider 2 46 is fixedly connected to a clamping assembly 47. The front and rear sides of the inner wall of the square mounting groove three 42 are fixedly connected with a slide bar 48, and the outer wall of the slide bar 48 is movably connected with a slide sleeve 49. A rectangular groove 40 is provided on the top of the mounting platform 41, and an arc-shaped fixed groove 401 is provided on the front side of the mounting platform 41 and extends to the rear side. The rear side of the inner wall of the arc-shaped fixed groove 401 is fixedly connected to the outer wall of the mounting tube 1. The rotating shaft 1 43 drives the screw rod 2 45 to rotate through the drive of the stepper motor 2 44. Since the slider 2 46 is threadedly connected to the screw rod 2 45, the slider 2 46 will move horizontally along the screw rod 2 45, thereby driving the clamping assembly 47 to move horizontally. When the clamping assembly 47 moves, the slide sleeve 49 will slide on the outer wall of the slide bar 48 to meet the casting of different lengths by the staff. In order to meet the needs of stainless steel pipes, the clamping assembly 47 includes a mounting block 471, a mounting groove 472 is provided at the bottom of the mounting block 471, a motor groove 2 is provided on the left side of the front side of the mounting block 471, a circular movable hole 5 penetrating into the inside of the motor groove 2 is provided on the left side of the inner wall of the mounting groove 472, and the inner wall of the circular movable hole 5 is movably connected with a rotating shaft 2 473, and a stepper motor 3 474 is fixedly connected to the left end of the rotating shaft 2 473, and the bottom of the stepper motor 3 474 is fixedly connected to the inner wall of the motor groove, and a bidirectional threaded rod 475 is fixedly connected to the right end of the rotating shaft 2 473, and a fixing sleeve 476 is movably connected to the middle position of the outer wall of the bidirectional threaded rod 475, and the outer wall of the fixing sleeve 476 is fixedly connected to the inner wall of the mounting groove 472, and the outer wall of the bidirectional threaded rod 475 There are two sliders 3 477 symmetrically threadedly connected, the bottom of the slider 3 477 is fixedly connected with an extension plate 478, the lower part of the two extension plates 478 close to each other is fixedly connected with an arc-shaped clamping block 479, the inner walls of the two arc-shaped clamping blocks 479 are movably connected with a stainless steel ring 470, the left and right sides of the bottom of the mounting block 471 are fixedly connected with support blocks 4701, the bottom of the left support block 4701 is fixedly connected to the top of the sliding sleeve 49, the bottom of the right support block 4701 is fixedly connected to the top of the slider 2 46, the outer wall of the stainless steel ring 470 is movably connected to the outer wall of the outermost circle of the tungsten alloy power spring 32 and the inner wall of the outer mold 51, and the rotating shaft 2 473 drives the bidirectional threaded rod 475 to rotate through the drive of the stepping motor 3 474.Since the bidirectional threaded rod 475 is threadedly connected with the two sliders 477, and the two sliders 477 are symmetrically arranged about the fixing sleeve 476, when the bidirectional threaded rod 475 rotates, the two sliders 477 will move toward or away from each other, thereby driving the arc-shaped clamping block 479 to clamp or release, making it easy to replace stainless steel rings 470 of different sizes. In the casting process, the stainless steel ring 470 is a part of the mold, and its shape and size will directly affect the shape and size of the final cast stainless steel pipe.

[0035] The working principle of the present invention is as follows: by starting the stepper motor 237, the rear screw rod 222 starts to rotate, and drives the front screw rod 222 to rotate through the connecting rod 21. Since the slider 223 is threadedly connected to the screw rod 222, the slider 223 starts to move horizontally along the screw rod 222. This displacement causes the movable plate 224 to swing accordingly under the action of the hinge point. The swinging behavior of the movable plate 224 will push the telescopic rod 226 to telescope along the circular movable hole 1 of the installation groove 225. As the telescopic rod 226 is extended and retracted, the fixed block 227 and the arc plate 228 connected thereto will expand outward or contract inward accordingly. Since the arc plate 228 is connected to the outer wall of the tungsten alloy power spring 32, when the arc plate 228 expands or contracts, it will stretch or compress the tungsten alloy power spring 32 accordingly. The tungsten alloy power spring 32 has good elasticity and resilience, and can provide sufficient supporting force when the arc plate 228 expands, and quickly recover to its original state when the arc plate 228 contracts. This telescopic movement allows the internal space of the mold structure 5 to be flexibly adjusted to meet the casting requirements of stainless steel pipes of different sizes. When a stainless steel pipe of smaller thickness needs to be cast, the stepper motor 237 drives the screw rod 222 to move the slider 223 away from the center point, and the movable plate 224 swings outward accordingly, the telescopic rod 226 extends, and the fixed block 227 and the arc plate 228 expand outward, thereby stretching the tungsten alloy power spring 32. At this time, the internal space of the outer mold 51 becomes smaller to adapt to the casting of stainless steel pipes of smaller thickness. During the casting process, the casting tube 52 is used to inject molten stainless steel liquid into the outer mold 51 and the tungsten alloy power spring 32.

[0036] Driven by the stepper motor 44, the shaft 1 43 drives the screw rod 2 45 to rotate. Since the slider 2 46 is threadedly connected to the screw rod 2 45, the slider 2 46 will move horizontally along the screw rod 2 45, thereby driving the clamping assembly 47 to move horizontally. When the clamping assembly 47 moves, the sliding sleeve 49 will slide on the outer wall of the sliding rod 48 to meet the needs of the staff for casting stainless steel pipes of different lengths. Driven by the stepper motor 3 474, the shaft 2 473 drives the bidirectional threaded rod 475 rotates. Since the bidirectional threaded rod 475 is threadedly connected with the two sliders 477, and the two sliders 477 are symmetrically arranged about the fixed sleeve 476, when the bidirectional threaded rod 475 rotates, the two sliders 477 will move toward or away from each other, thereby driving the arc-shaped clamping block 479 to clamp or loosen, making it easy to replace the stainless steel ring 470 of different sizes. In the casting process, the stainless steel ring 470 is a part of the mold, and its shape and size will directly affect the shape and size of the stainless steel pipe finally cast.
