The adjusting assembly of the lower pressing assembly is driven to be connected to the center of the top of the steel pipe. The lifting assembly pushes the connecting plate and the upper ball at the bottom of the connecting plate to press down and contact the upper surface of the steel pipe. The embossing assembly and the limiting assembly limit the two sides of the steel pipe. The lower pressing assembly and the lifting assembly press the top of the steel pipe, and the upper surface of the lower ball directly contacts the lower surface of the steel pipe, so that the embossing assembly and the limiting assembly can ensure that the steel pipe does not jump or deviate when embossing the tail end of the steel pipe. The load bearing rod is arranged in the interior of the steel pipe. The load bearing rod and the embossing roller are located on the same horizontal line. When the steel pipe with a thin wall is embossed, the force applied by the embossing roller to the steel pipe is received by the load bearing rod, so that the steel pipe with a thin wall is prevented from being deformed.

Description

Technical Field

[0001] This invention relates to the field of steel pipe embossing devices, and particularly to a steel pipe embossing device for processing bicycle handlebars. Background Technology

[0002] Handlebars are an essential part of a bicycle, used when riding, pushing, or pulling the bike. You can't ride a bicycle without handlebars. They are the handlebars used to control direction on a motorcycle, similar to a steering wheel in a car. Currently, during the manufacturing process of bicycle handlebars, to increase friction, an embossing device is used to emboss the steel tube of the handlebar, creating interlaced patterns to increase friction.

[0003] However, current steel pipe embossing devices lack a limiting structure at the top of the steel pipe. Since the embossing of the handlebars is done before cutting, and the steel pipe is quite long, the lack of a fixing structure at the tail end makes it prone to skipping or shifting due to the pressure from the embossing rollers and limiting rollers during embossing. This results in uneven embossing at the tail end of the steel pipe. Secondly, existing steel pipe embossing devices for bicycle handlebars can only emboss thicker steel pipes. For thinner steel pipes, the embossing process can cause deformation due to pressure from the embossing rollers and limiting rollers. Therefore, these devices have high requirements for the steel pipes used and are not widely applicable.

[0004] To address the aforementioned problems, we propose a steel pipe embossing device for bicycle handlebar processing. Summary of the Invention

[0005] The purpose of this invention is to provide a steel pipe embossing device for bicycle handlebar processing. Its advantages are that it can prevent the steel pipe end from jumping or shifting and that it will not cause deformation of the steel pipe when embossing thin-walled steel pipes.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a steel pipe embossing device for processing bicycle handlebars, comprising a processing table, a movable component installed on the top of the processing table, an embossing component, a pressing component and a limiting component respectively installed on the top of the movable component, a lifting component also installed on the top of the movable component, and a plurality of lower ball bearings also provided on the top of the movable component, a fixed component installed on the top of the processing table, and a rotating component installed on the top of the fixed component.

[0007] By adopting the above technical solution, and by setting up embossing components, limiting components, pressing components, lifting components, and lower ball bearings, it can be ensured that the steel pipe will not jump or deviate during embossing, thus ensuring the stability and uniformity of the steel pipe embossing. By setting up a load-bearing component, the load-bearing component can be kept at the same level as the embossing roller. When the embossing roller applies force to the steel pipe, the load-bearing rod can bear the pressure applied by the embossing roller, thereby avoiding the problem of steel pipe deformation.

[0008] The present invention is further configured such that: the movable component includes a sliding plate, two electric slide tables are mounted on the top of the sliding plate, an electric slide rail bolted to the processing table is slidably connected inside the electric slide table, and the top of the sliding plate is rotatably sleeved with the surface of a plurality of lower ball bearings.

[0009] By adopting the above technical solution, a movable component is set to drive the embossing structure on the top of the movable component to move back and forth, thereby embossing different positions of the steel pipe.

[0010] After the steel pipe is placed between the embossing assembly and the limiting assembly, the electric slide table and electric slide rail are started to drive the sliding plate and the embossing structure on top to move back and forth. The electric slide rail is used to contact the lower surface of the steel pipe to prevent the steel pipe from shifting downward or jumping.

[0011] The present invention is further configured such that: the pressing component includes a connecting plate, a plurality of limiting posts are installed at the bottom of the connecting plate, an upper ball is rotatably sleeved at the top of the limiting post, and an adjustment component is provided at the top of the upper ball;

[0012] The adjustment assembly includes a fixed housing, inside which is a screw, and a threaded block is threadedly connected to the surface of the screw. The threaded block is bolted to the connecting plate on the side near the connecting plate. A guide groove is provided at the bottom of the fixed housing, and the interior of the guide groove is slidably connected to the surface of the threaded block. An adjustment motor is installed on one side of the fixed housing, and the output end of the adjustment motor is installed to the screw via a coupling.

[0013] Using the above technical solution, the pressing component is used to press down on the top of the steel pipe;

[0014] Specifically, the steel pipe is clamped by a three-jaw chuck, with the side of the steel pipe closest to the limit roller in contact with it. A cylinder is activated, pushing the embossing roller to contact the other side of the steel pipe. The regulating motor starts, and its output rotates, driving the screw to rotate. As the screw rotates, the threaded blocks on its surface, connected to the screw threadedly, move towards the limit roller when the screw rotates clockwise, and towards the embossing roller when it rotates counterclockwise. Simultaneously, the movement of the threaded blocks also drives the connecting plate, limit post, and upper ball bearings to move synchronously. The adjusting assembly drives the movement of the connecting plate, limit post, and upper ball bearings. Once the upper ball bearing moves to the top center of the steel pipe, the lifting component pushes the lowering component to descend. The upper ball bearing will then contact the upper surface of the steel pipe. The rotating component drives the three-jaw chuck of the fixing component to rotate, causing the steel pipe to rotate. As the steel pipe rotates, the upper ball bearing, due to contact with the smooth tube, will rotate inside the limiting post under friction. However, the connecting plate, the limiting post at its bottom, and the upper ball bearing will not move up and down under the push of the electric cylinder. Therefore, the lowering component can press down on the steel pipe to prevent it from jumping or shifting between the embossing roller and the limiting roller, thus ensuring the stability of the steel pipe.

[0015] The present invention is further configured such that: the lifting assembly includes a top plate, an electric cylinder is embedded inside the top plate, the bottom end of the electric cylinder is bolted to the top of the fixed shell, two guide rods are slidably connected inside the top plate, the bottom ends of the guide rods are installed to the top of the fixed shell, and two support frames are provided at the bottom of the top plate, the side of the support frame near the fixed shell is bolted to the support frame.

[0016] The above technical solution utilizes a lifting component to drive the lowering component to rise or fall.

[0017] Specifically, when the electric cylinder is started, its output end pushes the top plate and the ball bearings on its bottom to contact the steel pipe, limiting the movement of the steel pipe. When the electric cylinder is started again, its output end retracts, thereby causing the connecting plate and the ball bearings on its top to separate from the steel pipe, thus facilitating the unloading of the steel pipe after embossing.

[0018] The present invention is further configured such that: the fixing component includes a connecting seat, a rotating rod is sleeved inside the connecting seat, so a bearing is rotatably sleeved on the surface of the rotating rod, the surface of the bearing is fixedly sleeved with the inside of the connecting seat, and a three-jaw chuck is installed at one end of the rotating rod.

[0019] The above technical solution uses a fixed component to clamp the steel tube of a bicycle handlebar, and with the cooperation of a rotating component, the steel tube can be rotated.

[0020] The connecting seat is used to support the rotary motor and the rotating rod. The rotating rod is used to connect the three-jaw chuck, so that the three-jaw chuck can rotate synchronously with the rotating rod. The three-jaw chuck is used to clamp the steel pipe, which is convenient for positioning the steel pipe. The bearing is used to increase the stability of the rotating rod when it rotates.

[0021] The present invention is further configured such that: the rotating assembly includes a rotating motor, the surface of the rotating motor is mounted on a bracket and a connecting seat, a first pulley is fixedly sleeved on the surface of the output end of the rotating motor, a second pulley is connected to the surface of the first pulley via a belt drive, and the interior of the second pulley is fixedly sleeved on the surface of the rotating rod.

[0022] The above technical solution utilizes a rotating component to drive the rotating rod to rotate.

[0023] The output end of the rotary motor is started to rotate, which drives the pulley to rotate. When the pulley rotates, the belt pulls the rotating rod to rotate. The rotation of the rotating rod drives the three-jaw chuck and the steel pipe inside it to rotate. The rotation of the steel pipe makes it easier for the surface of the steel pipe to contact the embossing roller, thus making it easier for the embossing roller to emboss the surface of the steel pipe.

[0024] The present invention is further configured such that: the load-bearing component includes a load-bearing rod, two blocks are fixedly sleeved on the surface of the load-bearing rod, a semi-circular groove is provided on the top of the blocks, a limiting frame is sleeved on the surface of the blocks, a limiting screw is threaded into the internal part of the limiting frame, and a push-pull component is installed at the bottom of the processing table;

[0025] The push-pull assembly includes a push-pull motor. The surface of the push-pull motor is mounted to the bottom of the processing table via a bracket. A threaded rod is mounted on the output end of the push-pull motor via a coupling. A connecting plate is threaded onto the surface of the threaded rod. Connecting columns are bolted to both sides of the connecting plate. The top of the connecting columns is bolted to a limiting frame. Two guide grooves are opened inside the processing table. The interior of the guide grooves is slidably connected to the surface of the connecting columns.

[0026] By adopting the above technical solution, a load-bearing component is set up to support the inner wall of the steel pipe. The load-bearing rod corresponds to the embossing roller. When the embossing roller applies pressure to the steel pipe, the load-bearing rod can bear the pressure of the embossing roller, thereby ensuring that the steel pipe wall will not deform.

[0027] Specifically, the steel pipe needs to be fitted onto the surface of the load-bearing rod;

[0028] First, separate the two limit screws from the two limit frames respectively, then put the steel pipe on the surface of the load-bearing rod; install the steel pipe and the three-jaw chuck, then replace the semi-circular groove with a limit frame and use the limit screws to limit the limit frame;

[0029] Then, the push-pull motor starts and drives the threaded rod to rotate. The clockwise or counterclockwise rotation of the threaded rod drives the connecting plate to move the two connecting columns. In turn, the two connecting columns drive the two limit frames and the load-bearing rod that is limited by the two limit frames to move. Through the contact between the load-bearing rod and the inner wall of the steel pipe, the load-bearing rod will be aligned with the embossing roller on the same horizontal line. When the steel pipe rotates, the halo on the surface of the load-bearing rod will not affect the rotation of the steel pipe.

[0030] The present invention is further configured such that: a circular annular groove is provided on one side of the connecting seat, and two sliding blocks that are bolted to a three-jaw chuck are slidably connected inside the circular annular groove.

[0031] Using the above technical solution, the annular groove and sliding block are used to increase the stability of the embossing assembly during rotation.

[0032] In summary, the present invention has the following beneficial effects:

[0033] This invention uses an adjusting component of a pressing assembly to drive a connecting plate located at the center of the top of a steel pipe. A lifting assembly pushes the connecting plate and its bottom upper ball bearings downward to contact the upper surface of the steel pipe. An embossing assembly and a limiting assembly limit both sides of the steel pipe. By pressing down on the top of the steel pipe using the pressing and lifting assemblies, it is ensured that the steel pipe will not jump or deviate when the embossing and limiting assemblies are used to emboss the tail end of the steel pipe. Furthermore, the upper surface of the lower ball bearings directly contacts the lower surface of the steel pipe, so the steel pipe will not jump downward. This ensures the stability of the steel pipe tail end during embossing, as well as the uniformity and quality of the embossing.

[0034] By setting the support rod inside the steel pipe and driving the support rod to move through the push-pull assembly of the support component, the support rod and the embossing roller are placed on the same horizontal line. When embossing steel pipes with thin walls, the force applied by the embossing roller to the steel pipe is supported by the support rod, thereby preventing the thin-walled steel pipe from deforming due to the embossing pressure. As a result, the embossing of steel pipes by this device is no longer limited by the wall thickness, improving the applicability of the device to steel pipes with different wall thicknesses.

[0056] The present invention will be further described in detail below with reference to the accompanying drawings.

[0057] Example 1:

[0058] refer to Figure 1 - Figure 11 A steel pipe embossing device for bicycle handlebar processing includes a processing table 1. A movable component 2 is mounted on the top of the processing table 1. An embossing component 3, a pressing component 4, and a limiting component 5 are respectively mounted on the top of the movable component 2. A lifting component 6 is also mounted on the top of the movable component 2. Several lower ball bearings 13 are also provided on the top of the movable component 2. A fixed component 7 is mounted on the top of the processing table 1, and a rotating component 8 is mounted on the top of the fixed component 7. The pressing component 44 drives a connecting plate 41 to the center of the top of the steel pipe. The lifting component 6 pushes the connecting plate 41 and its bottom upper ball bearings 43 downwards to contact the upper surface of the steel pipe. The embossing component 3 and the limiting component 5 limit the two sides of the steel pipe. By pressing the top of the steel pipe with the pressing component 4 and the lifting component 6, the embossing component 3 and the limiting component 5 can be kept in place. When component 5 embosses the tail end of the steel pipe, the steel pipe will not jump or shift. Furthermore, the upper surface of the lower ball bearing 13 directly contacts the lower surface of the steel pipe, preventing the pipe from jumping downwards. This ensures the stability of the steel pipe during embossing, guarantees the uniformity of the embossing, and maintains the quality after embossing. By setting the support rod 91 inside the steel pipe and driving it to move via the push-pull assembly 96 of the support component 9, the support rod 91 and the embossing roller 34 are placed on the same horizontal line. When embossing thin-walled steel pipes, the force applied by the embossing roller 34 is absorbed by the support rod 91, preventing deformation of thin-walled steel pipes due to embossing pressure. This eliminates the wall thickness limitation of the device for embossing steel pipes, improving its applicability to steel pipes of different wall thicknesses.

[0059] refer to Figure 1 , Figure 2 and Figure 11The movable component 2 includes a sliding plate 21, with two electric sliding tables 22 mounted on the top of the sliding plate 21. The electric sliding tables 22 are slidably connected to an electric slide rail 23 that is bolted to the processing table 1. The top of the sliding plate 21 is rotatably sleeved with the surface of several lower ball bearings 13. By setting the movable component 2, the embossing structure on the top of the movable component 2 is driven to move back and forth, thereby embossing different positions of the steel pipe. After the steel pipe is placed between the embossing component 3 and the limiting component 5, the electric sliding tables 22 and the electric slide rail 23 are electrically driven to drive the sliding plate 21 and the embossing structure on its top to move back and forth. The electric slide rail 23 is used to contact the lower surface of the steel pipe to prevent the steel pipe from shifting downward or jumping.

[0060] refer to Figure 1 and Figure 2 The embossing assembly 3 includes a fixed plate 31, with a cylinder 32 embedded inside. An mounting plate 33 is installed at the output end of the cylinder 32. An embossing roller 34 is mounted on one side of the mounting plate 33. Two guide rods 35 are mounted on the side of the mounting plate 33 closest to the cylinder 32. The surfaces of the guide rods 35 are slidably connected to the interior of the fixed plate 31. Two sliding grooves 36 are also formed on one side of the fixed plate 31, with sliders 37 slidably connected inside the sliding grooves 36. The bottom of the fixed plate 31 is bolted to the top of the sliding plate 21. The embossing assembly 3 is used to apply force to emboss the steel pipe. In use, the steel pipe is clamped by a three-jaw chuck 73, and one side of the steel pipe... When the cylinder 32 starts, it pushes the mounting plate 33 and the embossing roller 34 to move towards the steel pipe. The embossing roller 34 contacts the other side of the steel pipe, and the embossing roller 34 and the limiting roller 52 can clamp the steel pipe. The embossing roller 34 will form embossing patterns on the surface of the steel pipe. As the steel pipe rotates, the embossing roller 34 rotates with the steel pipe, thus forming embossing patterns on the surface of the steel pipe. When the embossing roller 34 and the limiting roller 52 move to the tail end of the steel pipe, since the tail end of the steel pipe does not have a fixed structure, the steel pipe may jump or deviate. At this time, the lower ball bearing 13 and the lower pressing assembly 4 will press against the upper and lower surfaces of the steel pipe to ensure that the surface of the steel pipe is always in contact with the embossing roller 34.

[0061] refer to Figure 1 , Figure 3 and Figure 4 The pressing component 4 includes a connecting plate 41. Several limiting posts 42 are installed at the bottom of the connecting plate 41. An upper ball bearing 43 is rotatably sleeved at the top of the limiting post 42. An adjusting component 44 is provided at the top of the upper ball bearing 43.

[0062] The adjusting assembly 44 includes a fixed housing 4401, inside which is a screw 4402. A threaded block 4403 is threadedly connected to the surface of the screw 4402. The threaded block 4403 is bolted to the connecting plate 41 on the side closest to the connecting plate 41. A guide groove 4404 is formed at the bottom of the fixed housing 4401, and the interior of the guide groove 4404 is slidably connected to the surface of the threaded block 4403. An adjusting motor 4405 is mounted on one side of the fixed housing 4401, and the output end of the adjusting motor 4405 is connected to the screw 4402 via a coupling. Installation 402 involves pressing down on the top of the steel pipe using the pressing component 4. Specifically, the steel pipe is clamped by a three-jaw chuck 73, with the side of the steel pipe closest to the limiting roller 52 in contact with it. The cylinder 32 is activated, pushing the embossing roller 34 to contact the other side of the steel pipe. The regulating motor 4405 is activated, and its output rotates, causing the screw 4402 to rotate. As the screw 4402 rotates, the threaded block 4403 on its surface, being threadedly connected to it, causes the screw 4402 to rotate clockwise. When the screw 4402 rotates, the threaded block 4403 on its surface moves towards the limiting roller 52; conversely, the threaded block 4403 moves towards the embossing roller 34. Simultaneously, the movement of the threaded block 4403 also drives the connecting plate 41, the limiting post 42, and the upper ball bearing 43 to move synchronously. The adjusting component 44 drives the connecting plate 41, the limiting post 42, and the upper ball bearing 43 to move. Once the upper ball bearing 43 reaches the top center position of the steel pipe, the lifting component 6 pushes the lowering component 4 down, causing the upper ball bearing 43 to contact the upper surface of the steel pipe. The rotating component 8 drives the three-jaw chuck 73 of the fixed component 7 to rotate, which in turn drives the steel pipe to rotate. When the steel pipe rotates, the upper ball 43 rotates inside the limiting post 42 due to contact with the tube and friction. However, the connecting plate 41, the limiting post 42 at its bottom, and the upper ball 43 do not move up and down under the push of the electric cylinder 62. Therefore, the pressing component 4 can press down the steel pipe to prevent it from jumping or shifting between the embossing roller 34 and the limiting roller 52, thus ensuring the stability of the steel pipe.

[0063] refer to Figure 1 and Figure 2 The limiting component 5 includes a fixed base 51, and a limiting roller 52 is installed on one side of the fixed base 51. The limiting component 5 is used to contact the side of the steel pipe. The limiting roller 52 cooperates with the embossing roller 34 to facilitate the embossing roller 34 to emboss the steel pipe.

[0064] refer to Figure 1 and Figure 3The lifting assembly 6 includes a top plate 61, the bottom of which is installed on a fixed plate 31. An electric cylinder 62 is embedded inside the top plate 61, and the bottom end of the electric cylinder 62 is bolted to the top of the fixed shell 4401. Two guide rods 63 are also slidably connected inside the top plate 61, and the bottom ends of the guide rods 63 are installed on the top of the fixed shell 4401. Two support frames 64 are provided at the bottom of the top plate 61. The side of the support frame 64 near the fixed shell 4401 is bolted to the support frame 64, and the side of the support frame 64 near the fixed plate 31 is bolted to the slider 37. The lifting assembly 6 is used to push the pressing assembly 4 to rise or fall. Specifically, when the electric cylinder 62 is activated, its output end pushes the top plate 61 and the ball bearings 43 on its bottom to contact the steel pipe, limiting the movement of the steel pipe. When the electric cylinder 62 is activated again, its output end retracts, thereby causing the connecting plate 41 and the ball bearings 43 on its top to separate from the steel pipe, thus facilitating the unloading of the steel pipe after embossing.

[0065] refer to Figure 1 and Figure 9 The fixing component 7 includes a connecting seat 71, inside which a rotating rod 72 is sleeved. A bearing 74 is rotatably sleeved on the surface of the rotating rod 72. The surface of the bearing 74 is fixedly sleeved with the inside of the connecting seat 71. A three-jaw chuck 73 is installed at one end of the rotating rod 72. Through the setting of the fixing component 7, it is used to clamp the steel tube of the bicycle handlebars and can drive the steel tube to rotate with the cooperation of the rotating component 8. The connecting seat 71 is used to support the rotary motor 81 and the rotating rod 72. The rotating rod 72 is used to connect the three-jaw chuck 73 so that the three-jaw chuck 73 can rotate synchronously with the rotating rod 72. The three-jaw chuck 73 is used to clamp the steel tube and facilitate the positioning of the steel tube. The bearing 74 is used to increase the stability of the rotating rod 72 when rotating.

[0066] refer to Figure 1 and Figure 9 The rotating assembly 8 includes a rotating motor 81. The surface of the rotating motor 81 is mounted on the connecting seat 71 via a bracket. A pulley 82 is fixedly sleeved on the surface of the output end of the rotating motor 81. A pulley 83 is connected to the surface of the pulley 82 via a belt drive. The interior of the pulley 83 is fixedly sleeved on the surface of the rotating rod 72. The rotating assembly 8 is used to drive the rotating rod 72 to rotate. The rotating motor 81 starts its output end to rotate and drives the pulley 82 to rotate. When the pulley 82 rotates, it pulls the rotating rod 72 to rotate via the belt. The rotation of the rotating rod 72 drives the three-jaw chuck 73 and the steel pipe inside it to rotate. The rotation of the steel pipe facilitates the contact between the surface of the steel pipe and the embossing roller 34, thereby facilitating the embossing roller 34 to emboss the surface of the steel pipe.

[0067] refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 ,Figure 8 , Figure 9 and Figure 10 The load-bearing component 9 includes a load-bearing rod 91, with two square blocks 92 fixedly sleeved on the surface of the load-bearing rod 91. A semi-circular groove 93 is formed on the top of each square block 92, and a limiting frame 94 is fitted onto the surface of each square block 92. A limiting screw 95 is threaded into the internal part of the limiting frame 94. A push-pull component 96 is installed at the bottom of the processing table 1. The push-pull component 96 includes a push-pull motor 9601, whose surface is mounted to the bottom of the processing table 1 via a bracket. The output end of the push-pull motor 9601 is connected via a coupling. The device is equipped with a threaded rod 9602, and a connecting plate 9603 is threadedly connected to the surface of the threaded rod 9602. Connecting posts 9604 are bolted to both sides of the connecting plate 9603. The top of the connecting posts 9604 is bolted to the limiting frame 94. Two guide grooves 10 are formed inside the processing table 1, and the interior of the guide grooves 10 is slidably connected to the surface of the connecting posts 9604. A load-bearing component 9 is provided to support the inner wall of the steel pipe. The load-bearing rod 91 corresponds to the embossing roller 34, and the embossing roller 34 embosses the steel pipe. When the pipe is pressurized, the support rod 91 can withstand the pressure of the embossing roller 34, thus ensuring that the steel pipe wall will not deform. Specifically, the steel pipe needs to be fitted onto the surface of the support rod 91. First, separate the two limiting screws 95 from the two limiting frames 94 respectively, and then fit the steel pipe onto the surface of the support rod 91. Install the steel pipe and the three-jaw chuck 73, and then replace the limiting frame 94 with the semi-circular groove 93 for clamping, using the limiting screws 95 to limit the limiting frame 94. Then, the push-pull motor 960 is used to... 1. The start-up mechanism drives the threaded rod 9602 to rotate. The clockwise or counterclockwise rotation of the threaded rod 9602 drives the connecting plate 9603 to move the two connecting columns 9604. In turn, the two connecting columns 9604 drive the two limiting frames 94 and the load-bearing rod 91, which is limited by the two limiting frames 94, to move. Through the contact between the load-bearing rod 91 and the inner wall of the steel pipe, the load-bearing rod 91 will be aligned with the embossing roller 34 on the same horizontal line. When the steel pipe rotates, the halo on the surface of the load-bearing rod 91 will not affect the rotation of the steel pipe.

[0068] refer to Figure 9 A circular groove 11 is provided on one side of the connecting seat 71. Two sliding blocks 12, which are bolted to the three-jaw chuck 73, are slidably connected inside the circular groove 11. The circular groove 11 and the sliding blocks 12 are used to increase the stability of the embossing assembly 3 when it rotates.

[0069] Working principle:

[0070] First, remove the two limiting screws 95, fit the inside of the steel pipe and the surface of the support rod 91, insert one end of the steel pipe into the three-jaw chuck 73, and clamp and position it through the three-jaw chuck 73. At this time, the lower surface of the steel pipe will contact the lower ball 13, and the side of the steel pipe will contact the surface of the limiting roller 52. Then, thread the two limiting screws 95 and the limiting frame 94 in sequence to limit the support rod 91.

[0071] The push-pull motor 9601 is started to rotate its output end and drive the threaded rod 9602 to rotate. The clockwise rotation of the threaded rod 9602 will drive the connecting column 9604 and the two limit frames 94 and the load-bearing rod 91 to move towards the embossing roller 34. The load-bearing rod 91 is ready when its surface contacts the inner wall of the steel pipe. (It is worth noting that the load-bearing rod 91 is located inside the steel pipe and directly penetrates to the outside of the three-jaw chuck 73. When the three-jaw chuck 73 clamps the steel pipe, the load-bearing rod 91 will not be clamped by the three-jaw chuck 73.)

[0072] Then, the cylinder 32 is activated to push the mounting plate 33 and the embossing roller 34 to move. When the embossing roller 34 squeezes the steel pipe, the force applied by the embossing roller 34 to the steel pipe will be borne by the support rod 91. The support rod 91 ensures that the force applied by the embossing roller 34 to the steel pipe is only applied to the wall of the steel pipe and will not affect the overall shape of the steel pipe and cause deformation.

[0073] Then, the motor 4405 is started to drive the screw 4402 to rotate, and the screw 4402 drives the threaded block 4403 to move the connecting plate 41 and its top limiting post 42 and upper ball 43 to the center of the top of the steel pipe. The electric cylinder 62 is started to push the fixed shell 4401 and its bottom connecting plate 41, limiting post 42 and upper ball 43 down. The upper ball 43 contacts the upper surface of the steel pipe, and finally limits the upper, lower, left and right of the steel pipe.

[0074] Finally, embossing is performed, started by a rotary motor 81. The output of the rotary motor 81 drives pulley 82 to rotate, which in turn pulls pulley 83 via a belt. The rotation of pulley 83 drives the three-jaw chuck 73 to rotate, which in turn drives the steel pipe to rotate. As the steel pipe rotates, the embossing roller 34 also rotates, working in conjunction with the support rod 91 to apply pressure to the surface of the steel pipe for embossing. When the steel pipe completes one revolution of embossing, the electric slide rail 23 and the electric slide table 22 start and drive the sliding plate 21 and its top structure to move towards the tail end of the steel pipe. During the movement, the embossing roller 34 continuously presses against the steel pipe. During the embossing process, when the steel pipe reaches its tail end, the traditional embossing device, lacking a fixed structure at the tail end, can cause the pipe to jump or deviate due to shaking. However, in this device, the lower ball bearing 13 and the upper ball bearing 43 always move with the sliding plate 21. Therefore, the limiting roller 52 and the embossing roller 34 can limit the two sides of the steel pipe, while the lower ball bearing 13 and the upper ball bearing 43 can limit the upper and lower parts of the steel pipe. This ensures that the steel pipe will not jump or deviate during the embossing at the tail end. Not only the tail end, but the entire embossing of the steel pipe will remain stable under their limiting conditions.
