Description

Technical Field

[0001] This application relates to the technical field of retractable gate manufacturing, and in particular to a semi-automatic punching equipment for retractable gate pipes and a process for producing pipes using the equipment. Background Technology

[0002] In the production process of retractable gates, several square tubes are often required. To facilitate the installation of these square tubes, holes are usually punched at both ends of the tubes to form through holes. Then, a connecting pipe of a fixed size is inserted into the through hole to position the tubes and assemble them into a retractable gate.

[0003] In the existing technology, the operator places the square tube in the middle of the punch press and then drives the punch to press the square tube to form a through hole. At this time, it is difficult for the operator to position the square tube, that is, it is difficult to control the positional accuracy of the through hole. Furthermore, when the punch presses the metal square tube downward, the peripheral wall of the through hole will produce trumpet-shaped burrs. The burrs spread outward and around. Due to inertia, the waste pieces fall out of the through hole. However, the waste pieces are easily caught by the burrs, making it difficult for the waste pieces to be discharged, resulting in material blockage. Summary of the Invention

[0004] In order to improve the production quality of square tubes, this application provides a semi-automatic punching equipment for telescopic gate tubes and a process for producing tubes using the equipment, which can improve the convenience of operators in punching square tubes using the punching equipment and improve production efficiency.

[0005] This application provides a process for producing pipes, using the following technical solution:

[0006] A process for producing pipes includes the following processing steps:

[0007] S1: Square tube installation: One end of the square tube is inserted into the core, and the end face of the square tube abuts against the side of the stop portion of the core.

[0008] S2: Square tube limiting: The upper positioning seat is set on the top of the core. The upper positioning seat is used to position the part of the square tube that is inserted into the core. The limiting mechanism on one side of the base limits the end of the square tube away from the core.

[0009] S3: Through hole opening: The punch is aligned with the center point of the long side of the core, and the punch is driven by the punching drive mechanism to punch the square tube to obtain a through hole.

[0010] S4: Burr removal: The outer deburring head drive assembly drives the outer deburring head to clean the burrs on the top surface of the square tube near the peripheral wall of the through hole, and the inner deburring head drive assembly drives the inner deburring head to clean the burrs on the inner top surface of the square tube near the peripheral wall of the through hole.

[0011] S5: Waste material blowing: The waste material accumulated between the upper positioning seat and the top surface of the square tube, and between the inner top surface of the square tube and the core, is blown away by the blowing mechanism.

[0012] By adopting the above technical solution, before punching the square tube, the operator first inserts one end of the square tube into the core. The upper positioning seat limits the height of the part where the square tube and the core are inserted, which helps to improve the installation stability of the square tube. Under the action of the punching drive mechanism, the punch can be driven to punch a through hole. Compared with the existing technology, the operator can easily complete the installation of the square tube, making the position of the through hole of each square tube the same, improving the positional accuracy of the through hole. Moreover, by removing the burrs on the periphery of the through hole of the square tube, the finished quality of the square tube can be improved, and the occurrence of waste pieces being caught by burrs can be reduced. With the cooperation of the blowing mechanism, the waste chips accumulated between the upper positioning seat and the top surface of the square tube, and between the inner top surface of the square tube and the core can be blown away, ensuring the smooth discharge of waste pieces, reducing material blockage, and improving production efficiency.

[0013] Preferably, the processing steps for limiting the square tube further include the following processing steps:

[0014] S2.1: Limiting mechanism adjustment: The limiting mechanism includes a side limiting plate and a fixed seat. Loosen the connecting nail of the fixed seat, adjust the distance between two adjacent fixed seats so that the two fixed seats are respectively placed at both ends of the square tube, and tighten the connecting nail of the fixed seat.

[0015] S2.2: Square tube fixing: Rotate the side limiting plate outward, and place the square tube in the fixing seat. Rotate the side limiting plate towards the side closer to the square tube. The side limiting plate and the fixing seat form an installation cavity for the square tube to pass through. Push the square tube along the length direction of the fixing seat until the end face of the square tube abuts against the side of the stop part of the core.

[0016] S2.3: Square tube locking: Rotate the upper stop block towards the top surface of the square tube, and the abutting part of the upper stop block abuts against the top surface of the square tube.

[0017] By adopting the above technical solution, the operator can adjust the distance of the limiting mechanism to adapt it to square tubes of different lengths, which helps to ensure the installation stability of the square tube. Pushing the square tube along the length of the fixed seat, the cooperation between the fixed seat and the side limiting plate can provide guidance for the movement of the square tube, thereby ensuring the positioning accuracy of the square tube. When the upper stop block abuts against the square tube, it can limit the movement stroke of the square tube and limit the height of the square tube, reducing the phenomenon of the other end of the square tube lifting when the end of the square tube is punched, improving the installation stability of the square tube, and ensuring the quality of the through hole opening.

[0018] Preferably, the processing steps for creating the through hole also include the following processing steps:

[0019] S3.1: Punch punching: Stepping down on the foot pedal triggers a linkage control mechanism, which acts as a power source to drive the punching drive mechanism, which in turn drives the punch to move vertically.

[0020] S3.2: Punch Brake: When the punching drive mechanism drives the punch to press the square tube downwards, the punching drive mechanism is linked to the braking mechanism, and the braking mechanism controls the speed and stroke of the punch pressing downwards.

[0021] S3.3: Punch reset: After the punch passes through the top wall of the square tube, the end of the punch abuts against the top surface of the core, and the reset spring sleeved on the outer wall of the punch abuts against the top surface of the square tube. The reset spring provides elastic force for the punch to reset.

[0022] By adopting the above technical solution, the operator steps on the foot pedal, which in turn drives the control mechanism. The control mechanism drives the punching drive mechanism, which in turn drives the punch to press the square tube to obtain a through hole. Through the linkage braking mechanism, the braking mechanism controls the speed and stroke of the punch pressing downwards. On the one hand, this reduces energy waste, and on the other hand, it protects the punch and extends its service life. The return spring provides a buffer when the punch moves downwards and a return force when the punch moves upwards, making the production process of square tubes more energy-efficient and environmentally friendly, and meeting production requirements.

[0023] Preferably, the burr removal process further includes the following processing steps:

[0024] S4.1: Deburring the top surface of the square tube: The external deburring head driving component first moves the external deburring head closer to the top surface of the square tube and then drives the external deburring head to rotate, or the external deburring head driving component simultaneously drives the external deburring head closer to the top surface of the square tube and drives the external deburring head to rotate. When the square tube is manually pulled away from the core, the external deburring head mills the burrs on the top surface of the square tube near the peripheral wall of the through hole.

[0025] S4.2: Deburring the inner top surface of the square tube: The inner deburring head driving component first moves the inner deburring head closer to the inner top surface of the square tube and then drives the inner deburring head to rotate, or the inner deburring head driving component simultaneously drives the inner deburring head closer to the inner top surface of the square tube and drives the inner deburring head to rotate. When the square tube is manually pulled away from the core, the inner deburring head mills the burrs on the inner top surface of the square tube near the peripheral wall of the through hole.

[0026] By adopting the above technical solution, the external deburring drive component serves as the power source to drive the external deburring head to clean the burrs on the top surface of the square tube, and the internal deburring drive component serves as the power source to drive the internal deburring head to clean the burrs on the inner top surface of the square tube. This can effectively remove burrs from the square tube, improve the waste sheet discharge efficiency, and improve the production quality of the square tube.

[0027] Preferably, in the waste material blowing process, the blowing mechanism includes a first blowing nozzle and a second blowing nozzle, the first blowing nozzle being aligned with the position between the upper positioning seat and the top surface of the square tube, and the second blowing nozzle being aligned with the position between the inner top surface of the square tube and the core.

[0028] By adopting the above technical solution, the first blowing nozzle is aligned with the position between the upper positioning seat and the top surface of the square tube, and the second blowing nozzle is aligned with the position between the inner top surface of the square tube and the core, thereby achieving the function of quickly removing waste material, reducing material blockage, and ensuring production efficiency.

[0029] This application also provides a semi-automatic punching device for telescopic gate pipes, which adopts the following technical solution:

[0030] The semi-automatic punching equipment for telescopic gate pipes uses the same process as pipe production to punch pipes. It includes a base, a foot pedal, an operating mechanism, and a punching drive mechanism. The foot pedal is rotatably mounted on the bottom of the base. One end of the operating mechanism is assembled with the foot pedal, and the other end is assembled with the punching drive mechanism. A connecting spring is provided on the side wall of the base, and the end of the connecting spring is assembled with the foot pedal.

[0031] By adopting the above technical solution, the foot pedal, operating mechanism and punching drive mechanism work together to punch square tubes. The connecting spring helps the foot pedal to return to its original position and also plays a certain role in buffering and deceleration, reducing the risk of injury to operators due to operational errors. This gives the equipment good safety performance, and it is easy to implement, has low cost, and meets production needs.

[0032] Preferably, the operating mechanism includes: a movable track installed on the side wall of the base; a connecting slide rod slidably connected to the middle of the movable track; a mating rod rotatably connected to the end of the connecting slide rod away from the foot pedal; and a punching start assembly mounted on the mating rod, wherein the movable track is distributed on the side of the base near the foot pedal and the position where it is assembled with the base, and the end of the mating rod away from the connecting slide rod is rotatably connected to the base.

[0033] By adopting the above technical solution, when the operator steps down on the foot pedal, the connecting slide rod can slide vertically downward along the moving track. When the cooperating rod rotates downward, it can drive the punching starting component to move downward, providing a power source for the subsequent punching starting component, which is convenient for the operator to implement.

[0034] Preferably, the punching start assembly includes: a sliding groove formed on the base; a sliding rack slidably connected to the middle of the sliding groove; a fixed rod installed on the bottom wall of the sliding rack; a rotating shaft rotatably connected to the top of the base in the width direction; and a rotating gear installed on the rotating shaft, wherein the end of the fixed rod near the mating rod is hinged to the middle of the mating rod, the rotating gear meshes with the sliding rack, the punching drive mechanism is installed in the middle of the rotating shaft, and the brake mechanism is installed at the end of the rotating shaft away from the punching start assembly.

[0035] By adopting the above technical solution, when the rod rotates downward, it can drive the sliding rack to slide downward along the sliding groove, causing the rotating shaft and rotating gear to rotate, which in turn causes the punching starting component to drive the punch to punch. In this process, since the rotating shaft and the braking mechanism are linked together, the speed and stroke of the punch pressing downward can be controlled, which can reduce energy waste and protect the punch.

[0036] Preferably, the punching drive mechanism includes: a first rotating gear disposed in the middle of the rotating shaft; a first fixed column fixed to the side wall of the first rotating gear; a punch slide rail vertically installed in the base; an auxiliary drive assembly disposed on the punch slide rail; and a first swing rod with one end assembled to the first fixed column and the other end hinged to the auxiliary drive assembly, wherein the punch is fixed to the bottom of the swing rod, and the auxiliary drive assembly is used to drive the punch to move in the vertical direction.

[0037] By adopting the above technical solution, the rotating shaft drives the first rotating gear to rotate when it rotates. The first rotating gear drives the first swing arm to swing. The first swing arm drives the auxiliary drive component to slide along the punch slide rail. Under the action of the auxiliary drive component, the punch can punch a hole in the square tube to obtain a through hole. The punching drive mechanism has a simple structure, strong correlation between mechanisms, and quick and effective braking action, ensuring the continuity of equipment production.

[0038] Preferably, the auxiliary drive assembly includes: a second rotating gear rotatably connected to the base; a second fixed column fixed to the side wall of the second rotating gear; a pulley assembly rotatably connected to the punch slide rail; a connecting belt wound around the pulley assembly; a second rocker arm with one end assembled to the second fixed column and the other end rotatably connected to the pulley assembly; and a mounting block disposed on the connecting belt, wherein the first rotating gear meshes with the second rotating gear, the end of the first rocker arm away from the first rotating gear is hinged to the mounting block, and the punch is fixed on the mounting block.

[0039] By adopting the above technical solution, the first rotating gear drives the second rotating gear to rotate, and the second rotating gear drives the second swing arm to swing. With the cooperation of the connecting belt, the second swing arm can drive the pulley group to slide along the punch slide rail, so that the punch fixed on the mounting block can also reciprocate along the length direction of the punch slide rail. The setting of the auxiliary drive component further improves the stability of the punch, so that the punch can be guaranteed to move in the same vertical line, which is conducive to improving the production quality of square tubes.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] 1. Compared with existing technologies, operators can easily complete the installation of square tubes, ensuring that the position of the through holes of each square tube is the same, thus improving the positional accuracy of the through holes. By removing burrs from the periphery of the through holes of the square tubes, the finished product quality of the square tubes can be improved, and the occurrence of waste pieces being caught by burrs can be reduced. With the cooperation of the blowing mechanism, the waste chips accumulated between the upper positioning seat and the top surface of the square tube, and between the inner top surface of the square tube and the core can be blown away, ensuring the smooth discharge of waste pieces, reducing material blockage, and improving production efficiency.

[0042] 2. By adjusting the distance of the limiting mechanism, the operator can adapt it to square tubes of different lengths, which helps ensure the installation stability of the square tube. Pushing the square tube along the length of the fixed seat, the cooperation between the fixed seat and the side limiting plate can guide the movement of the square tube, thereby ensuring the positioning accuracy of the square tube. When the upper stop block abuts against the square tube, it can limit the movement stroke of the square tube and limit the height of the square tube, reducing the phenomenon of the other end of the square tube lifting when the end of the square tube is punched, improving the installation stability of the square tube, and ensuring the quality of the through hole opening.

[0048] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0049] This application provides a process for producing pipes, using the following technical solution:

[0050] Reference Figure 1 and Figure 4 A process for producing pipes includes the following processing steps:

[0051] S1: Installation of Square Tube 1: Take a long square tube 1 made of metal. The inside of the square tube 1 is hollow. The wall thickness of the square tube 1 is set as A. The core 2 is integrally formed into a rectangular body. According to the position of the through hole 11 cut on the square tube 1, that is, measure the straight distance between the edge of the through hole 11 and the end face of the square tube 1 close to the through hole 11, this distance is set as L. Cut a rectangular notch with a length dimension of 2L and a height dimension of 1A on the core 2, so that the core 2 is divided into an extension part 21 and a stop part 22. After cutting the rectangular notch, the extension part 21... The height dimension of the square tube 1 is smaller than the height dimension of the stop part 22. The shape and size of the extension part 21 are adapted to the inner cavity of the square tube 1. When the core 2 is installed on the base 3, the side of the core 2 with the rectangular notch faces downward, and the extension part 21 points out of the base 3. The operator inserts one end of the square tube 1 into the core 2, so that the end face of the square tube 1 abuts against the side of the stop part 22 of the core 2. The inner bottom surface of the square tube 1 abuts against the top surface of the extension part 21 near the rectangular notch. A gap is reserved between the inner top surface of the square tube 1 and the side of the extension part 21 away from the rectangular notch.

[0052] S2: Square tube 1 limit: The upper positioning seat 31 is set on the top of the core 2. The upper positioning seat 31 is used to position and limit the height of the part where the square tube 1 and the core 2 are inserted, which helps to improve the installation stability of the square tube 1. The limiting mechanism on one side of the base 3 limits the end of the square tube 1 away from the core 2, reducing the phenomenon of the other end of the square tube 1 lifting up when the end of the square tube 1 is punched, thus improving the installation stability of the square tube 1.

[0053] Reference Figure 2 and Figure 3 The processing steps for limiting the square tube 1 also include the following processing procedures:

[0054] S2.1: Limiting mechanism adjustment: The limiting mechanism includes a side limiting plate 321 and a fixed seat 322. The operator loosens the connecting nail of the fixed seat and adjusts the distance between two adjacent fixed seats 322 so that the two fixed seats 322 are respectively placed at both ends of the square tube 1. Then tighten the connecting nail of the fixed seat to adapt to square tubes 1 of different lengths.

[0055] S2.2: Fixing the square tube 1: Rotate the side limiting plate 321 outward, and place the square tube 1 in the fixing seat 322. Rotate the side limiting plate 321 towards the side closer to the square tube 1. The side limiting plate 321 and the fixing seat 322 form an installation cavity 323 for the square tube 1 to pass through. Push the square tube 1 along the length direction of the fixing seat 322. The cooperation between the fixing seat 322 and the side limiting plate 321 can provide guidance for the movement of the square tube 1 until the end face of the square tube 1 abuts against the side of the stop part 22 of the core 2, ensuring that the square tube 1 moves in the same straight line.

[0056] S2.3: Locking of square tube 1: Rotate the upper stop block 325 towards the top surface of square tube 1. The abutting part of the upper stop block 325 abuts against the top surface of square tube 1, which can stably install square tube 1 on the base 3 and ensure the installation stability of square tube 1.

[0057] S3: Through hole 11 is made: The punch 87 is aligned with the center point of the long side of the core 2, and the punch 87 is driven by the punching drive mechanism to punch the square tube 1 to obtain the through hole 11.

[0058] The machining process for creating the through hole 11 also includes the following machining steps:

[0059] S3.1: Punch 87 punch: Press down on foot pedal 33 (reference) Figure 1 The foot pedal 33 is linked to the control mechanism, which acts as a power source to drive the punching drive mechanism, which in turn drives the punch 87 to move vertically.

[0060] S3.2: Punch 87 Brake: When the punching drive mechanism drives the punch 87 to punch the square tube 1 downwards, the punching drive mechanism is linked to the braking mechanism. The braking mechanism controls the downward punching speed and stroke of the punch 87 to reduce energy waste and protect the punch 87, thereby extending the service life of the punch 87.

[0061] S3.3: Punch 87 Reset: After punch 87 passes through the top wall of square tube 1, the end of punch 87 abuts against the top surface of core 2. The reset spring 871 sleeved on the outer wall of punch 87 abuts against the top surface of square tube 1. The reset spring 871 provides elastic force for the reset of punch 87. The reset spring 871 provides a buffer when punch 87 moves downward and provides a reset elastic force when punch 87 moves upward, making the production process of square tube 1 more energy-saving and environmentally friendly.

[0062] S4: Deburring: The external deburring head drive assembly drives the external deburring head 44 (see reference). Figure 4 The inner deburring head drive assembly drives the inner deburring head 45 to clean the burrs on the top surface of the square tube 1 near the periphery of the through hole 11.

[0063] Reference Figure 1 and Figure 4 The deburring process also includes the following steps:

[0064] S4.1: Deburring the top surface of square tube 1: The outer deburring head drive assembly first causes the outer deburring head 44 to approach the top surface of square tube 1 and then drives the outer deburring head 44 to rotate, or the outer deburring head drive assembly simultaneously drives the outer deburring head 44 to approach the top surface of square tube 1 and drives the outer deburring head 44 to rotate. When the square tube 1 is manually pulled away from the core 2, the outer deburring head 44 mills the burrs on the top surface of square tube 1 near the periphery of the through hole 11.

[0065] S4.2: Deburring the inner top surface of square tube 1: The inner deburring head drive assembly first causes the inner deburring head 45 to approach the inner top surface of square tube 1, and then drives the inner deburring head 45 to rotate, or the inner deburring head drive assembly simultaneously drives the inner deburring head 45 to approach the inner top surface of square tube 1 and drives the inner deburring head 45 to rotate. When the square tube 1 is manually pulled away from the core 2, the inner deburring head 45 mills the burrs on the inner top surface of square tube 1 near the periphery of the through hole 11.

[0066] S5: Waste material blowing: The waste material accumulated between the upper positioning seat 31 and the top surface of the square tube 1, and between the inner top surface of the square tube 1 and the core 2 is blown away by the blowing mechanism.

[0067] The blowing mechanism includes a first blowing nozzle and a second blowing nozzle (not shown in the figure). The first blowing nozzle is aligned with the position between the upper positioning seat 31 and the top surface of the square tube 1, and the second blowing nozzle is aligned with the position between the inner top surface of the square tube 1 and the core 2. This enables the rapid removal of waste material, ensures the smooth discharge of waste sheets, reduces material blockage, and improves production efficiency.

[0068] This application also provides a semi-automatic punching device for telescopic gate pipes, which adopts the following technical solution:

[0069] Reference Figure 1 and Figure 2 This is a semi-automatic punching machine for telescopic gate pipes. It uses the same process as pipe production to punch pipes. The machine includes a base 3, a foot pedal 33, an operating mechanism, and a punching drive mechanism. The foot pedal 33 is rotatably mounted on the bottom of the base 3. One end of the operating mechanism is assembled with the foot pedal 33, and the other end is assembled with the punching drive mechanism. A connecting spring 34 is provided on the side wall of the base 3. The end of the connecting spring 34 is assembled with the foot pedal 33. The connecting spring 34 helps the foot pedal 33 to return to its original position and also plays a certain role in buffering and decelerating, reducing the risk of injury to operators due to operational errors and giving the equipment good safety performance.

[0070] Specifically, the base 3 is installed on the working ground, and a work platform is fixed in the middle of the base 3. The core 2 is fixed on the work platform (see reference). Figure 4 The core 2 is fixed to the workbench by screws. An adjustment bracket 326 and two sets of limit mechanisms are provided at the input end of the base 3. (Refer to...) Figure 2 and Figure 3 The limiting mechanism includes a side limiting plate 321, a fixed seat 322, and several fixed seat connecting pins. The fixed seat 322 is fixed to the adjusting frame 326 by the fixed seat connecting pins. That is, the operator can adjust the distance between the two fixed seats 322 by loosening the fixed seat connecting pins and pushing the fixed seat 322 to adapt to square tubes 1 of different lengths. In this embodiment, the side limiting plate 321 is hinged to the side of the fixed seat 322 that extends out of the adjusting frame 326. The side limiting plate 321 and the fixed seat 322 form an installation cavity 323 for the square tube 1 to pass through.

[0071] The operator rotates the side limiting plate 321 outward, places the square tube 1 inside the fixed seat 322, rotates the side limiting plate 321 towards the side closer to the square tube 1, and pushes the square tube 1 along the length of the fixed seat 322 until the end face of the square tube 1 abuts against the side of the stop part 22 of the core 2, thus completing the assembly between the square tube 1 and the core 2.

[0072] To further improve the installation stability of the square tube 1, a fixed top plate 324 is welded to the top surface of the fixed base 322. The fixed top plate 324 has an installation groove. An upper stop block 325 is rotatably connected to the fixed top plate 324 near the installation groove. The shape of the upper stop block 325 depends on the situation. In the embodiment of this application, the upper stop block 325 is a right-angled trapezoidal plate, and a stop slope is provided on the fixed top plate 324.

[0073] When the operator rotates the upper stop block 325 clockwise, the long right-angle side of the upper stop block 325 abuts against the stop inclined surface when the upper stop block 325 reaches its maximum angle. When the operator rotates the upper stop block 325 counterclockwise, the upper bottom of the upper stop block 325 abuts against the top surface of the square tube 1 when the upper stop block 325 reaches its maximum angle, which can further lock the square tube 1 and thus improve the installation stability of the square tube 1.

[0074] To achieve the punching of the square tube 1, refer to... Figure 1 and Figure 2 The operating mechanism includes a moving track 51, a connecting slide rod 52, a mating rod 53, and a punching start assembly. Specifically, the moving track 51 is installed on the side wall of the base 3, so that the moving track 51 is distributed on the side of the base 3 near the position where the foot pedal 33 is assembled with the base 3. The connecting slide rod 52 is slidably connected to the middle of the moving track 51. The mating rod 53 is rotatably connected to the end of the connecting slide rod 52 away from the foot pedal 33. The end of the mating rod 53 away from the connecting slide rod 52 is rotatably connected to the base 3. The punching start assembly is assembled on the mating rod 53.

[0075] More specifically, the punching starting assembly includes a sliding groove, a sliding rack 62, a fixed rod 63, a rotating shaft 64, and a rotating gear 65 formed on the base 3. The sliding rack 62 is slidably connected to the middle of the sliding groove. The fixed rod 63 is installed on the bottom wall of the sliding rack 62. The end of the fixed rod 63 near the mating rod 53 is hinged to the middle of the mating rod 53. The rotating shaft 64 is rotatably connected to the top of the base 3 along its width direction. The rotating gear 65 is installed on the rotating shaft 64 so that the rotating gear 65 meshes with the sliding rack 62.

[0076] When the operator presses down on the foot pedal 33, the connecting slide rod 52 can slide vertically downward along the moving track 51. When the cooperating rod 53 rotates downward, it can drive the sliding rack 62 to slide downward along the sliding groove, causing the rotating shaft 64 and the rotating gear 65 to rotate. In this embodiment, the punching drive mechanism is installed in the middle of the rotating shaft 64, and a brake mechanism is installed at the end of the rotating shaft 64 away from the punching start assembly.

[0077] Reference Figure 1 and Figure 2The punching drive mechanism includes a first rotating gear 71, a first fixed column 72, a punch slide rail 73, an auxiliary drive assembly, and a first rocker arm 74. Specifically, the first rotating gear 71 is located in the middle of the rotating shaft 64, the first fixed column 72 is fixed to the side wall of the first rotating gear 71, the punch slide rail 73 is vertically installed in the base 3, the auxiliary drive assembly is located on the punch slide rail 73, one end of the first rocker arm 74 is assembled with the first fixed column 72, and the other end is hinged to the auxiliary drive assembly. Moreover, the punch 87 is fixed to the bottom of the rocker arm, and the punch 87 can be driven to move vertically through the auxiliary drive assembly.

[0078] More specifically, the auxiliary drive assembly includes a second rotating gear 81, a second fixed column 82, a pulley assembly, a connecting belt 84, a second rocker arm 85, and a mounting block 86. The second rotating gear 81 is rotatably connected to the base 3, so that the first rotating gear 71 meshes with the second rotating gear 81. The second fixed column 82 is fixed to the side wall of the second rotating gear 81. The pulley assembly includes two pulleys 83, both of which are rotatably connected to the punch slide rail 73. At the same time, the connecting belt 84 is wound around the two pulleys 83. One end of the second rocker arm 85 is assembled with the second fixed column 82, and the other end is rotatably connected to the pulley 83 close to the second rocker arm 85. The mounting block 86 is fixed to the connecting belt 84. The end of the first rocker arm 74 away from the first rotating gear 71 is hinged to the mounting block 86. The punch 87 is fixed to the mounting block 86.

[0079] In this embodiment, when the rotating shaft 64 rotates, it drives the first rotating gear 71 to rotate. The first rotating gear 71 drives the first rocker arm 74 to swing. The first rotating gear 71 drives the second rotating gear 81 to rotate. The second rotating gear 81 drives the second rocker arm 85 to swing. With the cooperation of the connecting belt 84, the second rocker arm 85 can drive the pulley group to slide along the punch slide rail 73, so that the punch 87 fixed on the mounting block 86 can also reciprocate along the length direction of the punch slide rail 73. The interrelationship between the various mechanisms of the punching equipment is strong, the braking action is quick and effective, ensuring the continuity of equipment production and improving the production quality of square tube 1.

[0080] Reference Figure 1 and Figure 2 The braking mechanism includes an adjusting pulley 91, an adjusting belt 92, and an adjusting spring 93. In this embodiment, the adjusting pulley 91 is located at the end of the rotating shaft 64 away from the rotating gear 65. The adjusting belt 92 is wound around the outer wall of the adjusting pulley 91, so that one end of the adjusting belt 92 is fixedly connected to the base 3 and the other end is fixedly connected to the adjusting spring 93. The end of the adjusting spring 93 away from the adjusting belt 92 is fixedly connected to the base 3.

[0081] When the rotating shaft 64 rotates, it can drive the adjusting pulley 91 to rotate. The adjusting belt 92 and the adjusting spring 93 can provide a buffer and deceleration effect for the rotation of the adjusting pulley 91, which can limit the maximum rotation angle of the adjusting pulley 91, making the punch 87 punching the square tube 1 more energy-efficient.

[0082] In order to remove the burrs on square tube 1, refer to...

[0083] After punch 87 completes punching the square tube 1, the operator pulls the square tube 1 out along the adjusting frame 326, and starts the external deburring drive cylinder 41 and the external deburring drive motor 43. The external deburring drive cylinder 41 drives the external deburring head 44 to move closer to the top wall of the square tube 1, and the external deburring drive motor 43 drives the external deburring head 44 to rotate, which can remove the burrs on the top surface of the square tube 1.

[0084] Furthermore, the outer deburring head 44 and the inner deburring head 45 have the same structure, and the outer deburring drive assembly and the inner deburring drive assembly have the same structure. In this embodiment, the inner deburring drive assembly will not be described in detail.
