Abstract
Description
Technical Field
[0001] This utility model relates to the field of stainless steel pipe technology, and in particular to a stainless steel pipe end shaping device. Background Technology
[0002] During the production and use of stainless steel pipes, the pipe ends and the pipe body may be deformed or uneven. These problems will affect the connection quality, sealing performance and overall appearance of the stainless steel pipes.
[0003] Currently, there is a lack of devices on the market that can effectively shape both the ends and the body of stainless steel pipes at the same time. Traditional shaping methods often only target a single part, which is cumbersome and the shaping effect is difficult to guarantee. Usually, only the inside of the pipe can be shaped, and the external shaping effect is poor, which cannot meet the quality requirements of stainless steel pipes in actual production and use.
[0004] Therefore, developing a device capable of comprehensively and efficiently shaping the ends and body of stainless steel pipes is of significant practical importance. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of traditional shaping methods in the prior art, which often only target a single part, are cumbersome to operate, and have difficulty in guaranteeing the shaping effect, thus failing to meet the quality requirements of stainless steel pipes in actual production and use. Therefore, this invention proposes a stainless steel pipe end shaping device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A stainless steel pipe end shaping device includes a frame and a shaping pipe. A support platform is fixedly installed at the bottom of the frame, and a placement groove for placing the shaping pipe is opened at the top of the support platform.
[0008] A shaping assembly is symmetrically arranged on both sides of the frame and is used to shape the ports of the shaping pipe.
[0009] A drive assembly, located on one side of the frame, is used to drive the shaping assembly to move;
[0010] The pipe shaping component, which is linked to the drive component, is used to shape the pipe body of the shaping pipe.
[0011] Specifically, by operating the driving component, the shaping component is moved to insert the frustum block into both ends of the shaping pipe and expand it to achieve port shaping. At the same time, the pipe body shaping component is linked to apply radial pressure to the outer surface of the shaping pipe by the arc-shaped clamp to achieve pipe body shaping, thereby completing the shaping operations of the port and the pipe body simultaneously.
[0012] In one possible design, the shaping assembly includes a circular hole on the side of the frame, through which a shaping block slides. A frustum block is fixedly mounted at one end of the shaping block, a side rod is fixedly connected to one side of the shaping block, and an L-shaped block is fixedly connected to one end of the side rod.
[0013] In one possible design, the drive assembly includes a bidirectional lead screw rotatably mounted between two fixed side plates, the fixed side plates being fixedly connected to one side of the frame, one side of the fixed side plates having a clearance groove for making way for L-shaped blocks, the bidirectional lead screw threaded through the two L-shaped blocks, and one end of the bidirectional lead screw being fixedly connected to an operating hole.
[0014] In one possible design, the tube shaping assembly includes a connecting slider slidably disposed within a strip-shaped hole. A vertical plate is fixedly connected to one side of the connecting slider. An elliptical groove is formed on one side of the vertical plate. A round rod is slidably connected inside the elliptical groove. A rectangular block is fixedly connected to one end of the round rod. An arc-shaped clamping plate is fixedly installed at one end of the rectangular block.
[0015] In one possible design, a fixed strip plate is fixedly installed on one inner wall of the frame, and the fixed strip plate has a strip hole in the middle position; a fixed plate is fixedly installed on the bottom inner wall of the frame, the fixed plate is located between the fixed strip plate and the support platform, and the fixed plate has an oblique hole and a horizontal hole communicating with the oblique hole inside, and the round rod passes through the horizontal hole and the oblique hole to form a sliding fit.
[0016] In one possible design, a connecting rod is fixedly connected to one side of the connecting slider, one end of the connecting rod is fixedly connected to the L-shaped block, the two connecting rods are staggered vertically, and the sum of the thicknesses of the two connecting rods is equal to the thickness of the connecting slider.
[0017] In one possible design, the support platform is welded and fixed to the middle position of the inner wall at the bottom of the frame, and the placement groove is a V-shaped or arc-shaped groove.
[0018] In this application, during use, the shaping tube is pushed from one side to the top of the support platform and placed inside the placement slot. At this time, the operating hole can be rotated, which drives the bidirectional screw to rotate. The bidirectional screw drives the two L-shaped blocks to move closer to each other, the two L-shaped blocks drive the two side rods to move closer to each other, the two side rods drive the two shaping blocks to move closer to each other, and the two shaping blocks drive the two frustum blocks to move closer to each other. The two frustum blocks are first inserted into both ends of the shaping tube and continuously spread the two ends of the shaping tube to achieve the shaping function.
[0019] Furthermore, when the L-shaped block approaches, it also causes the two connecting rods to move closer together. The two connecting rods then cause the two connecting sliders to move closer together. The connecting sliders slide inside the strip-shaped hole, and the sum of the thicknesses of the two connecting rods is the thickness of the connecting sliders. The two connecting rods do not collide when they approach each other. The connecting sliders cause the vertical plate to move laterally, and the vertical plate causes the two round rods to move laterally. The round rods gradually move from the inside of the oblique hole to the inside of the horizontal hole, thus causing the two round rods to move closer together. The two round rods then cause the two rectangular blocks to move closer together, and the two rectangular blocks cause the two arc-shaped clamps to move closer together. The arc-shaped clamps shape the outer surface of the shaping pipe, ensuring the shaping effect of the shaping pipe and making it convenient to use.
[0020] Beneficial effects: The stainless steel pipe end shaping device of this application drives the shaping component to move through the drive component. It can not only insert the frustum block into both ends of the shaping pipe and open it to achieve end shaping, but also enable the arc-shaped clamp to shape the outer surface of the shaping pipe through the linkage of components such as the connecting rod, connecting slider, vertical plate, and round rod. This achieves simultaneous shaping of the stainless steel pipe end and the pipe body, improves shaping efficiency, and ensures shaping effect.
[0021] In use, simply place the shaping pipe in the placement slot of the support platform, rotate the operating hole to drive the bidirectional lead screw to rotate, thereby driving the relevant components to complete the shaping operation. The operation is simple and convenient, reducing the labor intensity of the operator.
[0022] The device features two staggered connecting rods, with the sum of their thicknesses equal to the thickness of the connecting slider. This design prevents the rods from colliding when they approach each other, ensuring smooth and stable operation. Furthermore, the ingenious design of the round rod's movement within the oblique and transverse holes allows for precise manipulation of the curved clamps to shape the pipe.
[0023] By comprehensively shaping the ends and body of the stainless steel pipe, the problems of poor connection quality and poor sealing caused by deformation and unevenness of the stainless steel pipe are effectively solved, thereby improving the overall quality of the stainless steel pipe and meeting the requirements of actual production and use.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0031] In one embodiment; reference Figure 1-5 A shaping device includes a frame 1 for shaping a pipe 4. A support platform 6 is welded and fixed to the middle of the bottom inner wall of the frame 1, and a placement groove 12 on the top of the support platform 6 is used to support the pipe 4. A fixing strip plate 13 is bolted to the inner wall of one side of the frame 1, and two symmetrically arranged connecting sliders 25 slide through a strip hole 14 at the center of the fixing strip plate 13. A vertical plate 23 is welded and fixed to the side of the connecting slider 25. Symmetrical elliptical grooves 22 are formed on the surface of the vertical plate 23. A round rod 24 is embedded in each elliptical groove 22. A rectangular block 21 is welded and fixed to the end of the round rod 24, and an arc-shaped clamping plate 7 is fixedly installed at the end of the rectangular block 21.
[0032] A fixing plate 3 is fixedly installed on the inner wall of the bottom of the frame 1 using countersunk bolts. This plate is located between the fixing strip plate 13 and the support platform 6. Four sets of oblique holes 11 are formed inside the fixing plate 3. The end of each set of oblique holes 11 connects to a horizontal hole 10. A round rod 24 passes through the horizontal hole 10 and slides into the oblique hole 11. A connecting rod 16 is welded and fixed to the side of the connecting slider 25. The connecting rods 16 are arranged in an alternating pattern, and their total thickness is equal to the thickness of the connecting slider 25. The ends of the connecting rods 16 are connected to the side of the L-shaped block 19 using threaded fasteners.
[0033] In actual use, the shaping pipe 4 is pushed into the placement groove 12 along the surface of the support platform 6. The operating hole 18 is rotated to drive the bidirectional lead screw 8 to rotate, driving the two L-shaped blocks 19 to move towards each other along the relief groove 20. The L-shaped blocks 19 drive the shaping blocks 2 to move synchronously through the side rods 17, so that the frustum blocks 5 are gradually inserted into both ends of the shaping pipe 4. As the frustum blocks 5 continue to feed, their conical surfaces evenly expand the deformed parts of the ends, completing the end shaping.
[0034] During the movement of the L-shaped block 19, the connecting rod 16 drives the two connecting sliders 25 to slide towards each other within the strip-shaped hole 14. The connecting sliders 25 drive the vertical plate 23 to move horizontally, causing the round rod 24 to slide along the inclined hole 11 towards the horizontal hole 10. Due to the guiding effect of the inclined hole 11, the distance between the two round rods 24 gradually decreases, and the rectangular block 21 drives the arc-shaped clamping plate 7 to close synchronously. When the inner wall of the arc-shaped clamping plate 7 contacts the outer surface of the shaping pipe 4, it generates uniform radial pressure, correcting the deformed parts of the pipe body into a standard cylindrical shape.
[0035] This invention can be used in the field of stainless steel pipes, as well as in other fields where this device is applicable.
[0036] In another embodiment; reference Figure 1-5 A stainless steel pipe end shaping device is disclosed, used in the field of stainless steel pipe shaping. The shaping components, symmetrically arranged on both sides of a frame 1, include circular holes 15 formed in the side walls of the frame 1. A shaping block 2, slidably passing through the circular holes 15, has a frustum block 5 fixedly mounted at its end. A side rod 17 is welded to the side of the shaping block 2, and its end is welded to an L-shaped block 19. Two symmetrically arranged fixed side plates 9 are welded to the side of the frame 1. A bidirectional lead screw 8 is assembled between the two fixed side plates 9, passing through both fixed side plates 9 and forming a rotational engagement. A clearance groove 20 on the side of the fixed side plate 9 provides movement space for the L-shaped block 19. The two ends of the bidirectional lead screw 8 are threaded to the two L-shaped blocks 19, and an operating hole 18 is welded to one end for driving the lead screw to rotate.
[0037] This device achieves simultaneous port opening and shaping with tube clamping and shaping via a single power source. The drive system, consisting of a bidirectional lead screw 8 and an L-shaped block 19, ensures precise alignment of the two shaping components. A composite guide structure composed of an oblique hole 11 and a transverse hole 10 transforms horizontal movement into the radial closing action of the arc-shaped clamping plate 7, achieving mechanical transmission for circumferential shaping of the tube within a limited space. The staggered arrangement and thickness-matched design of the connecting rods 16 avoids motion interference while ensuring continuous power transmission, resulting in a compact overall structure and convenient operation.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
