Description

Technical Field

[0001] This utility model relates to the field of steel pipe heading technology, specifically, it mainly relates to a steel pipe self-opening and retracting heading machine. Background Technology

[0002] Before machining specific structures (such as threaded joints, sealing bolt ends, and positioning bosses) at the ends of steel pipes, a pipe heading process is required. This process uses mechanical pressing or shaping to form the pipe ends into a shape that meets the requirements of subsequent assembly, connection, or use, preventing problems such as loose connections, seal failure, or breakage under stress during pipeline laying and mechanical assembly. Currently, the equipment commonly used for pipe heading is the traditional manual heading machine. However, traditional manual heading machines lack a self-opening and closing mechanism for steel pipes. When clamping the steel pipe, operators need to manually adjust the opening and closing degree of the clamp to hold it, which is cumbersome and time-consuming, thus reducing the processing efficiency of pipe heading. Utility Model Content

[0006] According to one embodiment of the present invention, the self-opening and retracting driving component includes a vertical driving member, a clamping connecting seat, and a plurality of clamping and fixing members; the vertical driving member is disposed on the clamping bracket, the clamping connecting seat is disposed at the output end of the vertical driving member, and the plurality of clamping and fixing members are spaced apart at the bottom of the clamping connecting seat in a horizontal direction, and each second clamping member is connected to a clamping and fixing member.

[0007] According to one embodiment of the present invention, each first clamping member and each second clamping member is provided with a clamping groove on its end face. The clamping grooves provided on each first clamping member and the clamping grooves provided on each second clamping member are directly opposite each other. Multiple heading dies are directly opposite to the clamping grooves provided on multiple first clamping members. When any first clamping member and the corresponding second clamping member approach each other, a steel pipe fixing cavity is formed between the two corresponding clamping grooves.

[0008] According to one embodiment of the present invention, a steel pipe head groove is also provided on the side of each clamping groove away from the steel pipe fixing component.

[0009] According to one embodiment of the present invention, the bottom of the clamping groove provided on the first clamping member is at the same height as the bottom of the steel pipe placement position.

[0010] According to one embodiment of the present invention, the heading execution component includes a slide rail assembly, a support plate, and multiple heading dies; the slide rail assembly is mounted on the frame, the support plate is mounted on the slide rail assembly and connected to the output end of the heading drive assembly, and the multiple heading dies are detachably arranged side by side on the support plate, with each heading die having a heading insertion position on the side facing the first clamping member.

[0011] According to one embodiment of the present invention, the heading execution component further includes multiple heading seats and multiple mounting blocks. The multiple heading seats are arranged side by side on the frame and face the heading insertion position. Each heading seat is detachably provided with multiple mounting blocks arranged side by side, and each mounting block is also provided with a socket.

[0014] The beneficial effects of this application are as follows: When heading steel pipes, multiple steel pipes are first placed one by one on the steel pipe placement positions and on the first clamping members corresponding to the steel pipe placement positions. That is, one end of the steel pipe is placed on the steel pipe placement position, and the other end is placed on the first clamping member. The self-opening and retracting drive component drives the second clamping member to move, and the second clamping member moves closer to the first clamping member, so that the other end of the steel pipe is clamped and fixed between the first clamping member and the second clamping member.

[0020] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings: like Figure 1 As shown, Figure 1This is a three-dimensional structural diagram of the self-opening and heading machine for steel pipes in this embodiment. This embodiment provides a self-opening and heading machine for steel pipes, including a frame 1, a steel pipe fixing assembly 2, a self-opening and clamping assembly 3, a heading drive assembly 4, and a heading execution assembly 5. The steel pipe fixing assembly 2, the self-opening and clamping assembly 3, and the heading drive assembly 4 are sequentially mounted on the frame 1. The heading execution assembly 5 is fixed to the output end of the heading drive assembly 4. The steel pipe fixing assembly 2, the self-opening and clamping assembly 3, the heading drive assembly 4, and the heading execution assembly 5 cooperate sequentially along the steel pipe processing flow, realizing fully automated operation of the entire process from positioning and placement of the steel pipe, self-opening and clamping, to automatic heading processing.

[0021] Please refer to the following: Figure 2-3 and Figure 5 As shown, Figure 2 This is a three-dimensional structural diagram of the steel pipe fixing assembly in the embodiment; Figure 3 This is a three-dimensional structural diagram of the self-opening and retracting clamping assembly in the embodiment; Figure 5 This is a three-dimensional structural diagram of the heading execution component in the embodiment. The steel pipe fixing component 2 is mounted on the frame 1 and has multiple steel pipe placement positions 220 arranged side-by-side. The self-opening and retracting clamping component 3 includes a clamping bracket 31, a self-opening and retracting drive component 32, and multiple clamping components 33. The clamping bracket 31 is mounted on the frame 1, and the self-opening and retracting drive component 32 is mounted on the clamping bracket 31. Each clamping component 33 includes a first clamping member 331 and a second clamping member 332. The first clamping member 331 is fixed side-by-side on the frame 1, and the second clamping member 332... The holding members 332 are arranged side by side on the self-opening and retracting drive component 32, and each first clamping member 331 is directly opposite a second clamping member 332. Each first clamping member 331 is also directly opposite a steel pipe placement position 220. The heading drive assembly 4 is arranged on the frame 1. The heading execution assembly 5 is fixed to the output end of the heading drive assembly 4. The heading execution assembly 5 has multiple heading dies 53 arranged side by side at one end facing the multiple first clamping members 331. Each heading die 53 is directly opposite a first clamping member 331.

[0022] The steel pipe fixing assembly 2 is used to initially position the steel pipe to be processed. The assembly has multiple steel pipe placement positions 220 arranged side-by-side. When feeding the steel pipe, one end of multiple steel pipes can be placed sequentially on each of the placement positions 220, thus supporting one end of each pipe. The other end of the steel pipe is then placed sequentially on a first clamping member 331 that corresponds to each of the placement positions 220. The self-opening / closing drive component 32 can move the second clamping member 332 towards the first clamping member 331, achieving automatic closing of both the first and second clamping members 331. The heading drive assembly 4 can be a servo motor to drive the heading execution assembly 5 to move. The heading execution assembly 5 is fixed to the output end of the heading drive assembly 4 and is used to complete the heading process of the steel pipe. The heading execution assembly 5 has multiple heading dies 53 arranged side by side at one end facing multiple first clamping members 331. Each heading die 53 is directly opposite a first clamping member 331. Thus, when the heading drive assembly 4 drives the heading execution assembly 5 to move, each heading die 53 moves towards the steel pipe fixed between the first clamping member 331 and the second clamping member 332 to head the steel pipe. After the heading is completed, the self-opening drive component 32 can drive the second clamping member 332 away from the first clamping member 331, realizing the automatic opening of the first clamping member 331 and the second clamping member 332, and the headed steel pipe can be removed. The above operation can then be repeated.

[0023] For further details, please review. Figure 2 The steel pipe fixing assembly 2 includes a fixing plate 21 and multiple fixing limit pins 22. The fixing plate 21 is mounted on the frame 1, and multiple parallel insertion interfaces 210 are provided near the top of the fixing plate 21. Each insertion interface 210 is connected to a fixing limit pin 22, and each fixing limit pin 22 has a steel pipe placement position 220 on the side facing the self-opening and retracting clamping assembly 3.

[0024] The fixing plate 21 has multiple parallel insertion ports 210 near its top, the number of which matches the number of clamping components 33. Each insertion port 210 is fitted with a fixed limiting pin 22. Each fixed limiting pin 22 has a steel pipe placement position 220 on the side facing the self-opening and retracting clamping assembly 3. The steel pipe placement position 220 has an L-shaped structure, which can stably support the steel pipe within the steel pipe placement position 220. The side of the steel pipe placement position 220 away from the self-opening and retracting clamping assembly 3 can provide a limit for the steel pipe, preventing the steel pipe from rolling or shifting before clamping. When feeding steel pipes, the operator only needs to place multiple steel pipes to be processed into their corresponding steel pipe placement positions 220 to initially limit the steel pipes.

[0025] To accommodate different types of steel pipes, the fixed limiting pin 22 is detachably inserted into the insertion interface 210. The first clamping member 331 is detachably fixed to the frame 1 by bolts, and the second clamping member 332 is also detachably fixed to the self-opening and retracting drive component 32 by bolts. Thus, when the steel pipe type changes, only the appropriate fixed limiting pin 22, the first clamping member 331, and the second clamping member 332 need to be replaced.

[0026] For further details, please review. Figure 3 The self-opening and retracting drive component 32 includes a vertical drive component 321, a clamping connection seat 322, and a plurality of clamping and fixing components 323. The vertical drive component 321 is disposed on the clamping bracket 31, the clamping connection seat 322 is disposed at the output end of the vertical drive component 321, and the plurality of clamping and fixing components 323 are spaced horizontally at the bottom of the clamping connection seat 322. Each second clamping component 332 is connected to a clamping and fixing component 323.

[0027] The vertical drive component 321 can be a servo electric cylinder. The output end of the vertical drive component 321 is set downward and rigidly connected to the clamping connection seat 322. The clamping connection seat 322 is made of metal plate and can transmit the driving force of the vertical drive component 321 to multiple clamping fasteners 323. Multiple clamping fasteners 323 are fixed at intervals along the horizontal direction at the bottom of the clamping connection seat 322. The number is the same as that of the clamping component 33. Each second clamping component 332 is fixed to a clamping fastener 323 by bolts, which makes the connection stable and easy to disassemble and assemble.

[0028] When steel pipes need to be clamped, the vertical drive 321 is activated, and its output end extends, driving the clamping connecting seat 322 to move downwards vertically. Simultaneously, the clamping connecting seat 322 drives multiple clamping and fixing parts 323 and the second clamping part 332 downwards, causing the second clamping part 332 to move closer to the first clamping part 331 until it engages with the first clamping part 331 to clamp the steel pipe. After the heading process is completed, the output end of the vertical drive 321 retracts, driving the clamping connecting seat 322, clamping and fixing parts 323, and the second clamping part 332 upwards, causing the second clamping part 332 to move away from the first clamping part 331, thus automatically opening the clamp and facilitating the operator to remove the processed steel pipe. The entire clamping process requires no manual adjustment of the clamp opening degree; it is entirely automated by the self-opening and retracting drive component 32.

[0029] For further details, please review. Figure 1 and 3 Please refer to them together. Figure 4 As shown, Figure 4This is a three-dimensional structural diagram of the first clamping member and the second clamping member when they are close together in the embodiment. Each first clamping member 331 has a clamping groove 330 on its end face, and each second clamping member 332 has a clamping groove 330 on its end face. The clamping grooves 330 on each first clamping member 331 and the clamping grooves 330 on each second clamping member 332 are directly opposite each other. The multiple heading dies 53 are directly opposite to the clamping grooves 330 on the multiple first clamping members 331. When any first clamping member 331 and the opposite second clamping member 332 are close together, a steel pipe fixing cavity 3301 is formed between the two opposite clamping grooves 330.

[0030] The clamping grooves 330 on the end faces of each first clamping member 331 and each second clamping member 332 have trapezoidal cross-sections. When any first clamping member 331 approaches the opposite second clamping member 332, a steel pipe fixing cavity 3301 is formed. The inner diameter of the steel pipe fixing cavity 3301 is the same as the outer diameter of the steel pipe, which can tightly clamp the steel pipe and prevent displacement of the steel pipe during processing. The reason why multiple heading dies 53 are aligned with the clamping grooves 330 on multiple first clamping members 331 is that when one end of the steel pipe is fixed in the steel pipe fixing cavity 3301, the heading drive assembly 4 drives the heading execution assembly 5 to move, so that the heading die 53 can be aligned with one end of the steel pipe to head one end of the steel pipe.

[0031] Furthermore, each clamping groove 330 is provided with a steel pipe head groove 3302 on the side away from the steel pipe fixing component 2. The diameter of the steel pipe head groove 3302 is larger than the diameter of the clamping groove 330, which is used to accommodate specific structures at the end of the steel pipe (such as threaded joints, sealing screw ports, positioning bosses, etc.), to avoid collision and interference between the end of the steel pipe and the first clamping member 331 and the second clamping member 332 during heading processing, while providing sufficient processing space for the heading execution component 5.

[0032] Furthermore, the bottom of the clamping groove 330 on the first clamping member 331 is at the same height as the bottom of the steel pipe placement position 220. This alignment ensures that when one end of the steel pipe is in the placement position 220 and the other end is in the clamping groove 330, the steel pipe is horizontal. When the self-opening / retracting drive component 32 moves the second clamping member 332 towards the first clamping member 331, one end of the steel pipe is in the placement position 220, and the other end simultaneously enters the steel pipe fixing cavity 3301 formed by the two clamping grooves 330. As the second clamping member 332 continues to move downwards, the steel pipe fixing cavity 3301 gradually shrinks until the steel pipe is tightly clamped. At this point, the end of the steel pipe is located in the steel pipe head groove 3302, preparing for subsequent heading processing. In addition, the first clamping member 331 and the second clamping member 332 are detachably connected by bolts. The first clamping member 331 and the second clamping member 332 with corresponding clamping grooves 330 can be replaced according to different diameter steel pipes, further expanding the processing range of the equipment.

[0033] For further details, please review. Figure 5 The heading execution component 5 includes a slide rail assembly 51, a support plate 52, and multiple heading dies 53. The slide rail assembly 51 is mounted on the frame 1, the support plate 52 is mounted on the slide rail assembly 51 and connected to the output end of the heading drive component 4, and the multiple heading dies 53 are detachably arranged side by side on the support plate 52. Each heading die 53 has a heading insertion position 530 on the side facing the first clamping member 331.

[0034] Multiple heading dies 53 are detachably mounted side-by-side on the support plate 52 via bolts, and the number of heading dies 53 is consistent with the number of clamping components 33. Furthermore, the shape and size of the heading insertion position 530 are designed according to the heading requirements of the steel pipe. By replacing different specifications of the heading dies 53, different heading shapes and steel pipe diameters can be processed. During steel pipe heading, the heading drive assembly 4 is activated. Driven by the heading drive assembly 4, the support plate 52 moves horizontally along the slide rail assembly 51 and moves towards the first clamping member 331. The support plate 52 also drives the multiple heading dies 53 to move towards the first clamping member 331. The heading insertion position 530 approaches the steel pipe clamped in the steel pipe fixing cavity 3301, and the steel pipe is headed.

[0035] Meanwhile, in order to adapt to different types of steel pipes, the heading die 53 is detachably bolted to the support plate 52. Thus, when the steel pipe type changes, only the appropriate heading die 53 needs to be replaced.

[0036] Furthermore, refer to the following: Figure 6 As shown, Figure 6This is a schematic diagram of the structure between the heading base and the mounting block in the embodiment. The heading execution component 5 also includes multiple heading bases 54 and multiple mounting blocks 55. The multiple heading bases 54 are arranged side by side on the frame 1 and face the heading insertion position 530. Each heading base 54 is detachably provided with multiple mounting blocks 55 arranged side by side, and each mounting block 55 is also provided with a socket 550. A through hole 540 is provided at the position directly opposite the heading base 54 and the socket 550. The socket 550, the directly opposite through hole 540, the directly opposite clamping groove 330, and the directly opposite heading insertion position 530 on any mounting block 55 are all at the same horizontal position.

[0037] The heading base 54 is made of metal and is used to fix the mounting blocks 55. Multiple mounting blocks 55 are detachably connected side-by-side to the heading base 54 by bolts. The number of mounting blocks 55 is the same as the number of heading dies 53. The insertion port 550 on any mounting block 55, its corresponding through hole 540, clamping groove 330, and heading insertion position 530 are all at the same horizontal position to ensure that the force transmission path is coaxial during heading processing and to avoid a decrease in processing quality due to positional deviation. When heading processing is performed, the heading die 53 and mounting blocks 55 of the corresponding specifications are selected. The heading die 53 is fixed to the support plate 52 with bolts, and the mounting blocks 55 are fixed to the heading base 54 with bolts, ensuring that the heading die 50, insertion port 555, through hole 540, and clamping groove 330 are at the same horizontal position.

[0038] To accommodate different types of steel pipes, the mounting block 55 is detachably bolted onto the headstock 54. Thus, when the steel pipe type changes, only the appropriate headstock 54 and mounting block 55 need to be replaced, thereby replacing the appropriate through hole 540 and socket 550.

[0039] Furthermore, each heading die 53 includes a heading socket 531 and a heading roller 532; the heading roller 532 is detachably inserted into the heading socket 531, and the end of the heading roller 532 facing the mounting block 55 is provided with a heading insertion position 530. When the heading drive assembly 4 drives the heading execution assembly 5 to move, any heading roller 532 sequentially passes through the insertion port 550 and the through hole 540 located at the same horizontal position.

[0040] During the heading process, the heading drive assembly 4 first drives the support plate 52 to move along the horizontal slide rail 512 towards the steel pipe. The support plate 52 drives the heading socket 531 and the heading roller 532 to move synchronously, ensuring that the heading roller 532, the socket 550, the through hole 540, and the clamping groove 330 are at the same horizontal position. Then, the heading roller 532 passes through the socket 550 and the through hole 540 in sequence, and finally the heading insertion position 530 contacts the end of the steel pipe. The heading drive assembly 4 continues to work, so that the heading insertion position 530 applies a set pressure to the end of the steel pipe, completing the heading process. After the process is completed, the heading drive assembly 4 drives the support plate 52 and the heading mold 53 to move in the opposite direction, and the heading roller 532 exits the through hole 540 and the socket 550, returning to the initial position, waiting for the next processing.

[0041] To accommodate different types of steel pipes, the heading socket 531 is detachably bolted to the support plate 52, and the heading roller 532 is detachably inserted into the heading socket 531. Thus, when the steel pipe type changes, only the appropriate heading socket 531 and heading roller 532 need to be replaced, or a heading roller 532 with a different heading insertion position 530 needs to be replaced.

[0042] For further details, please refer to Figure 5 The slide rail assembly 51 includes multiple horizontal sliders 511 and multiple horizontal slide rails 512; the multiple horizontal slide rails 512 are arranged relatively parallel on the frame 1, and at least one horizontal slider 511 is slidably provided on each horizontal slide rail 512, and the support plate 52 is fixedly connected to the multiple horizontal sliders 511.

[0043] The horizontal slide rail 512 can be a linear slide rail, and the horizontal slider 511 is clearance-fitted with the horizontal slide rail 512, allowing it to slide smoothly along the horizontal slide rail 512. The support plate 52 is fixedly connected to multiple horizontal sliders 511, ensuring that the support plate 52 remains horizontal during movement and preventing tilting. When the heading drive assembly 4 drives the support plate 52 to move, the support plate 52 drives the horizontal sliders 511 to slide along the horizontal slide rail 512. The horizontal slide rail 512 provides stable guidance for the horizontal sliders 511, ensuring that the support plate 52 and the heading die 53 move smoothly in the set direction, avoiding a decrease in heading processing quality due to movement deviation. Compared with the unguided structure of traditional equipment, the slide rail assembly 51 can significantly improve the movement stability of the heading execution assembly 5, further ensuring the heading processing quality.

[0044] In summary, first, select the corresponding specification fixed limit pin 22, insert it into the insertion interface 210, replace the first clamping member 331 and the second clamping member 332 with the corresponding specification clamping groove 330, replace the corresponding specification heading die 53, heading base 54 and mounting block 55, and ensure that the heading insertion position 530, through hole 540, insertion port 550 and clamping groove 330 on the heading die 53 are in the same horizontal position. At the same time, insert the heading roller 532 into the heading socket 531, and then the operator will place multiple steel pipes to be processed... The steel pipe is placed into multiple steel pipe placement positions 220, which support one end of the steel pipe to be processed. The other end of the steel pipe is placed sequentially onto the first clamping member 331, which is directly opposite each of the multiple steel pipe placement positions 220. The steel pipe placement positions 220 initially limit the steel pipe to be processed, preventing it from rolling or shifting. The other end is placed into the clamping groove 330 of the first clamping member 331, and the end of the steel pipe enters the steel pipe head groove 3302. Then, the vertical drive member 321 is activated. The output end extends, causing the clamping connecting seat 322, clamping fixing member 323, and second clamping member 332 to move downwards, so that the second clamping member 332 moves closer to the first clamping member 331. The clamping grooves 330 corresponding to the first clamping member 331 and the second clamping member 332 form a steel pipe fixing cavity 3301, tightly clamping the steel pipe and completing the automatic clamping of the steel pipe. The heading drive assembly 4 is started, driving the support plate 52 to move along the horizontal slide rail 512 towards the end of the steel pipe. The support plate 52 drives the heading mold 53 to move synchronously, and the heading roller 532 moves accordingly. The tube passes through the socket 550 and through hole 540, and the heading insertion position 530 contacts the end of the steel pipe and applies a set pressure to complete the heading process. Then, the heading drive assembly 4 drives the support plate 52 to move in the opposite direction, and the heading mold 53 returns to the initial position. The output end of the vertical drive component 321 retracts, which drives the clamping connection seat 322, the clamping fixing component 323 and the second clamping component 332 to move upward. The second clamping component 332 moves away from the first clamping component 331, the fixture opens automatically, and the operator takes out the processed steel pipe, thus completing one processing cycle.

[0045] The self-opening and retracting steel pipe heading machine of this embodiment realizes automatic opening and closing of the clamp through the self-opening and retracting clamping component 3, replacing the traditional manual clamping operation, greatly simplifying the operation process and reducing clamping time. At the same time, the parallel design of the steel pipe placement position 220, clamping groove 330, through hole 540, insertion port 550 and heading roller 532 can avoid the heading deviation. At the same time, by processing multiple steel pipes simultaneously, the processing efficiency is greatly improved and the heading processing quality is ensured. It effectively solves the defects of traditional manual heading machines, such as cumbersome operation, narrow processing range and low efficiency.
