Description

Technical Field

[0001] This application relates to the field of pipe processing technology, and in particular to an integrated machine for bending and punching pipes. Background Technology

[0002] With the continuous development of the social economy and the increasing level of science and technology, my country's manufacturing industry is also constantly developing. A pipe bending machine is a device that bends pipes into a predetermined arc. A punching machine is a punching device that can be applied to fixed pipes to punch holes on the surface of the pipes. Both pipe bending machines and punching machines play an important role in the manufacturing industry.

[0003] Regarding the aforementioned technologies, since existing pipe bending machines and punching machines can only perform a single process on pipe fittings, when processing pipe fittings, it is often necessary to first fix the pipe fittings on the pipe bending machine or punching machine for a single fixing process. Only after the pipe bending machine or punching machine has finished processing the pipe fittings can the relevant personnel transport the pipe fittings to the next process for further processing. This reduces the efficiency of pipe fitting processing. Summary of the Invention

[0004] To improve the efficiency of pipe fitting processing, this application provides an integrated pipe bending and punching machine.

[0005] This application provides a pipe bending and punching integrated machine, which adopts the following technical solution. A pipe bending and punching integrated machine includes a machine body, on which a pipe bending mechanism and a punching mechanism are provided. The pipe bending mechanism includes a pipe bending seat, a clamping assembly, and a pipe bending component. The pipe bending seat is rotatably connected to the machine body. The clamping assembly is disposed on the pipe bending seat and used to clamp the pipe. The pipe bending component is used to drive the pipe bending seat to rotate. The punching mechanism includes a mounting frame, a punching frame, and a punching component. One end of the mounting frame is mounted on the machine body, and the other end extends into the pipe. The punching frame is slidably connected to the end of the mounting frame extending into the pipe. The punching component is used to drive the punching frame to slide, thereby punching the pipe.

[0006] By adopting the above technical solution, compared with the prior art which requires two instruments to perform bending and punching processes on the pipe fittings separately, the bending and punching mechanisms of this application enable the punching frame on the mounting bracket to slide under the drive of the punching assembly, thereby contacting the inner wall of the pipe fitting and punching the pipe fitting. The pipe fitting can also be moved to the vicinity of the bending seat under the drive of the feeding mechanism, and abut against the bending seat under the action of the clamping assembly, thereby clamping and fixing the pipe fitting. Then, the bending assembly can drive the bending seat to rotate, causing the pipe fitting to bend along the bending seat. Thus, this application can perform bending and punching processes on the pipe fittings, improving the efficiency of pipe fitting processing, and effectively reducing the workload of relevant personnel.

[0007] Preferably, the machine body is also provided with a feeding mechanism, which includes a sliding frame, a sliding assembly, a fixed frame and a fixed claw. The sliding frame is slidably connected to the machine body, and the sliding direction of the sliding frame is towards the bend seat. The sliding assembly is used to drive the sliding frame to slide. The fixed frame is installed on the sliding frame and sleeved on the mounting frame. The fixed claw is installed on the fixed frame in the direction near the bend seat and is used to clamp the pipe fitting.

[0008] By adopting the above technical solution and specifically setting the feeding mechanism, the pipe fitting can be initially positioned by being sleeved outside the fixed frame. Then, the sliding frame can move under the drive of the sliding component, thereby driving the fixed claw to move to the periphery of the pipe fitting and accurately positioning the pipe fitting by clamping it. After clamping and positioning the pipe fitting, the sliding frame can move under the drive of the sliding component, thereby causing the pipe fitting to be displaced, and thus realizing the feeding of the pipe fitting.

[0009] Preferably, the machine body is also provided with a support mechanism, which includes a support frame and a support member. The support frame is located between the sliding frame and the pipe bend seat, and the support frame is located below the pipe and abuts against the bottom of the pipe. The bottom end of the support frame is rotatably connected to the machine body, and the support member is used to drive the support frame to rotate.

[0010] By adopting the above technical solution and setting the support mechanism, the support frame can rotate under the drive of the support component, so that the top of the support frame gradually approaches the bottom of the pipe and finally abuts against the bottom of the pipe, thereby supporting the bottom of the pipe. This reduces the probability of the pipe end bending and being damaged due to excessive force because the fixed claw only grips the end of the pipe, effectively ensuring the integrity of the pipe.

[0011] Preferably, the support mechanism further includes a clamping frame and a linkage assembly. The top end of the clamping frame is located above the pipe and abuts against the top end of the pipe. The clamping frame is rotatably connected to the machine body, and the linkage assembly is used to drive the clamping frame to rotate.

[0012] By adopting the above technical solution, the clamping frame and linkage component are configured so that the linkage component can drive the clamping frame to rotate, thereby causing the bottom end of the clamping frame to abut against the top of the pipe fitting. This allows the clamping frame and support frame to reposition the pipe fitting, further ensuring the accuracy of the pipe fitting positioning and thus guaranteeing the effectiveness of pipe bending and punching.

[0013] Preferably, the linkage assembly includes an intermediate frame, a transfer frame, and a linkage frame. One end of the intermediate frame is rotatably connected to the support frame, the other end of the intermediate frame is rotatably connected to the top of the transfer frame, the bottom end of the transfer frame is rotatably connected to the machine body, the linkage frame is sleeved on the clamping frame and slidably connected to the clamping frame, and the linkage frame is rotatably connected to the top of the transfer frame.

[0014] By adopting the above technical solution and specifically setting the linkage components, when the support frame rotates, the support frame can drive the rotating frame to rotate relative to a machine body through the intermediate frame, thereby causing the linkage frame to rotate together with the intermediate support frame. At the same time, the linkage frame drives the gripping frame to rotate. During this process, the gripping frame and the linkage frame slide together, thereby driving the gripping frame and making the rotation direction of the gripping frame opposite to that of the support frame.

[0015] Preferably, the sliding frame is further provided with a rotating component, the fixed frame is rotatably connected to the sliding frame, the fixed frame rotates along the axis of the pipe, and the rotating component is used to drive the fixed frame to rotate.

[0016] By adopting the above technical solution, the fixed frame and the sliding frame are rotatably connected, so that the fixed frame can drive the pipe to rotate through the fixed claw, thereby enabling the punching frame to punch holes at different positions on the side wall of the pipe. This increases the scope of application of this application, replaces manual rotation of the pipe, facilitates the operation of relevant personnel, and improves the efficiency of pipe processing.

[0017] Preferably, the pipe bending seat is further provided with a pipe bending frame, the pipe bending frame has a pipe bending groove, the clamping assembly includes a clamping frame, a connecting rod assembly and a driving component, the clamping frame is movably connected to the pipe bending seat, the clamping frame and the pipe bending frame are respectively located on both sides of the pipe, the pipe is located on the displacement path of the clamping frame, and the driving component drives the clamping frame to move through the connecting rod assembly.

[0018] By adopting the above technical solution and specifically setting the clamping assembly, the driving component can drive the clamping frame to move through the linkage group, thereby approaching the pipe bending frame, so that the clamping frame and the pipe bending frame clamp the pipe, and the side wall of the pipe is in contact with the inner wall of the pipe bending groove. Thus, when the pipe bending assembly drives the pipe bending seat to rotate, it abuts against the pipe through the inner wall of the pipe bending groove, thereby achieving the bending of the pipe.

[0019] Preferably, the linkage assembly includes a first rotating rod, a first connecting rod, a second connecting rod, and a second rotating rod. The bottom end of the first rotating rod is rotatably connected to the bend seat, and the top end of the first rotating rod is rotatably connected to the clamping frame. One end of the first connecting rod is rotatably connected to the clamping frame and also rotatably connected to the top end of the first rotating rod. The other end of the first connecting rod is rotatably connected to one end of the second connecting rod, and the other end of the second connecting rod is rotatably connected to the clamping frame. The driving component includes a driving cylinder, which is rotatably connected to the bend seat. The rotatable connection between the first connecting rod and the second connecting rod is rotatably connected to the piston rod of the driving cylinder.

[0020] By adopting the above technical solution and specifically configuring the connecting rod assembly, the driving cylinder can drive the rotational connection between the first connecting rod and the second connecting rod to move through the displacement of its own piston rod. This causes the connecting rod assembly to move the clamping frame closer to or away from the pipe bending frame, thereby achieving the clamping or loosening of the pipe fitting. At the same time, the specific configuration of the connecting rod assembly enables the first rotating rod, the first connecting rod, the second connecting rod, and the second rotating rod to effectively support the clamping frame, thereby ensuring the stability when clamping the pipe fitting.

[0021] Preferably, the machine body includes a main body and a lifting frame, the lifting frame being slidably connected to the main body, the pipe bending mechanism being located on the lifting frame, and the main body also having a lifting component for driving the lifting frame to slide. Both the pipe bending frame and the clamping frame are provided with positioning frames, both of which are located below the pipe bending groove, and the two positioning frames are used to clamp and fix the pipe.

[0022] By adopting the above technical solution, the lifting frame and lifting components are configured so that the lifting components can slide by driving the lifting frame, thereby aligning the pipe bending groove with the pipe fitting for pipe bending. The clamping block is then lifted to align with the pipe fitting for clamping, thereby performing the punching process on the pipe fitting. This effectively facilitates the replacement of pipe fitting processing steps and makes the operation of relevant personnel easier.

[0023] Preferably, the punching assembly includes a drive frame and a displacement member. The end of the drive frame away from the bend seat is slidably connected to the machine body, and the other end of the drive frame extends into the mounting frame and is close to the bend seat. A drive part is also provided on the end of the drive frame that extends into the mounting frame. The drive part is inclined. The punching frame is sleeved on the drive part and slidably connected to the drive part. The displacement member is used to drive the drive frame to slide.

[0024] By adopting the above technical solution and specifically setting the punching assembly, the displacement component can drive the drive frame to slide, thereby causing the drive unit to drive the punching frame to move through its own sliding. Under the constraint of the mounting frame, the punching frame slides relative to the mounting frame, thereby enabling the punching frame to punch the pipe fitting, thus facilitating the operation of relevant personnel.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The setting of the pipe bending mechanism and the punching mechanism allows the punching frame on the mounting bracket to slide under the drive of the punching assembly, thereby contacting the inner wall of the pipe fitting and punching the pipe fitting. The pipe fitting can also be moved to the vicinity of the pipe bending seat under the drive of the feeding mechanism, and abut against the pipe bending seat under the action of the clamping assembly, thereby clamping and fixing the pipe fitting. Then, the pipe bending assembly can drive the pipe bending seat to rotate, causing the pipe fitting to bend along the pipe bending seat. This allows the present application to perform pipe bending and punching processes on the pipe fitting, improving the efficiency of pipe fitting processing and effectively reducing the workload of relevant personnel. 2. The support mechanism is designed so that the support frame can rotate under the drive of the support components, so that the top of the support frame abuts against the bottom of the pipe, thereby supporting the bottom of the pipe. At the same time, the clamping frame can cooperate with the support frame to further position the pipe, thereby ensuring the accuracy of the pipe positioning and thus ensuring the effect of pipe bending and punching. 3. The lifting frame and lifting components are designed so that the lifting components can slide by driving the lifting frame, thereby aligning the pipe bending groove with the pipe fitting for bending. The clamping block is then lifted to align with the pipe fitting for clamping, thereby facilitating the punching process. This effectively facilitates the change of pipe fitting processing steps and makes the operation easier for relevant personnel. Attached Figure Description

The pipe bending seat 31 is rotatably connected to the machine body 1. The clamping assembly 32 clamps the pipe through the pipe bending seat 31. The pipe bending assembly 33 is used to drive the pipe bending seat 31 to rotate. The punching mechanism 4 includes a mounting frame 41, a punching frame 42, and a punching assembly 43. One end of the mounting frame 41 is mounted on the machine body 1, and the other end extends into the pipe. The punching frame 42 is slidably connected to the end of the mounting frame 41 that extends into the pipe. The punching assembly 43 is used to drive the punching frame 42 to slide, thereby punching the pipe.

[0037] Reference Figure 1 and Figure 2 The machine body 1 includes a main body 11 and a lifting frame 12. The lifting frame 12 is located at one end of the main body 11 along its own length direction and is slidably connected to the main body 11. The sliding direction of the lifting frame 12 is vertical. The main body 11 is also provided with a lifting component 5. Optionally, in this embodiment, the lifting component 5 is a hydraulic cylinder. The cylinder body is fixedly installed to the end of the main body 11 by bolts. The piston rod of the hydraulic cylinder is vertically arranged and fixedly connected to the lifting frame 12 by bolts.

[0038] Reference Figure 1 and Figure 2 The lifting frame 12 includes a frame body 121 and a processing base 122. The frame body 121 is slidably connected to the main body 11, and the processing base 122 is slidably connected to the frame body 121 via a slide rail.

The cylinder body of the adjusting cylinder 6 is fixedly installed on the processing base 122 by bolts. The piston rod of the adjusting cylinder 6 is arranged along the width direction of the main body 11 and is fixedly connected to the processing base 122 by bolts.

[0039] Reference Figure 1 and Figure 2 The feed mechanism 2 is mounted on the main body 11, and the pipe bending mechanism 3 and the punching mechanism 4 are mounted on the machining base 122. A support mechanism 7 is also provided on the main body 11, located at one end of the main body 11 near the machining base 122. The support mechanism 7 includes a support frame 71 and a support member 72. The bottom end of the support frame 71 is rotatably connected to the main body 11 via a bearing, and the top end of the support frame 71 extends upward and is located below the mounting bracket 41. A rotating cylinder 73 is also provided on the top end of the support frame 71, sleeved on the bottom end of the support frame 71 and rotatably connected to the support frame 71 via a pin. The top end of the rotating cylinder 73 abuts against the bottom end of the pipe.

[0040] Reference Figure 1Optionally, in this embodiment, the support 72 is a rotating hydraulic cylinder 261. The cylinder body of the rotating hydraulic cylinder 261 is rotatably connected to the main body 11 via a bracket and a pin. The piston rod of the rotating hydraulic cylinder 261 is fixedly connected to the bottom end of the support frame 71 by bolts. When the piston rod of the rotating cylinder retracts, the support frame 71 rotates, causing the rotating cylinder 73 on the support frame 71 to approach the pipe and eventually abut against the bottom end of the pipe.

[0041] Reference Figure 1 and Figure 4 The feeding mechanism 2 includes a sliding frame 21, a sliding assembly 22, a fixed frame 23, and a fixed jaw 24. The sliding frame 21 is slidably connected to the body 11 via a slide rail, and the sliding direction of the sliding frame 21 is the length direction of the body 11. Optionally, in this embodiment, the sliding assembly 22 is a combination of a servo motor, a pulley, and a lead screw.

The lead screw extends along the sliding direction of the sliding frame 21, is rotatably connected to the body 11, passes through the sliding frame 21, and is threadedly connected to the sliding frame 21. The servo motor, pulley, lead screw, and the way they are combined are all existing technologies in the art, and therefore will not be described in detail here. Optionally, in other embodiments, the sliding assembly 22 can also be a hydraulic cylinder or an electric telescopic rod, or other mechanical device.

[0042] Reference Figure 1 , Figure 4 and Figure 5 The fixing frame 23 is cylindrical and is fitted over the mounting frame 41. One end of the fixing frame 23 is rotatably connected to the sliding frame 21 via a bearing. The other end of the fixing frame 23 extends towards the bend seat 31 and is coaxially arranged with the mounting frame 41. The sliding frame 21 is also provided with a rotating component 25. Optionally, in this embodiment, the rotating component 25 is a combination of a servo motor and a pulley. The servo motor is fixedly installed inside the body 11, and the servo motor drives the fixing frame 23 to rotate via the pulley. Both the servo motor and the pulley are prior art, so they will not be described in detail here.

[0043] Reference Figure 4 and Figure 5 The fixed jaw 24 includes a connecting frame 241 and three clamping jaws 242. One end of the connecting frame 241 is fixedly connected to the end of the fixed frame 23 away from the sliding frame 21 by bolts. The three clamping jaws 242 are arranged at equal angles around the circumference of the connecting frame 241. One end of each clamping jaw 242 is rotatably connected to the end of the connecting frame 241 away from the sliding frame 21 by a pin. The end of each clamping jaw 242 away from the sliding frame 21 protrudes outward, and each protruding part has a guide surface near the end of the sliding frame 21.

[0044] Reference Figure 4 and Figure 5Each clamping claw 242 is provided with a return spring 243 on the side wall near the connecting frame 241. One end of the return spring 243 is embedded in the clamping claw 242 and abuts against the inner wall of the clamping claw 242. The other end of the return spring 243 is embedded in the connecting frame 241 and abuts against the inner wall of the connecting frame 241.

[0045] Reference Figure 1 , Figure 4 and Figure 5 The sliding frame 21 is also equipped with a drive assembly 26, which includes a rotating cylinder 261, a shift fork ring 262, and a connecting sleeve 263. The connecting sleeve 263 is fitted onto the fixed frame 23 and is slidably connected to the fixed frame 23. One end of the connecting sleeve 263 extends towards the connecting frame 241 and abuts against the guide surface on each clamping claw 242. The cylinder body of the rotating cylinder 261 is rotatably connected to the sliding frame 21 via a bracket and a pin. The rotating cylinder 261 is located on one side of the sliding frame 21 along the width direction of the body 11. The piston rod of the rotating cylinder 261 is rotatably connected to the shift fork ring 262 via a pin. The shift fork ring 262 is fitted onto the outside of the connecting frame 241 and is fixedly connected to the connecting frame 241 by clamping.

[0046] Reference Figure 1 , Figure 4 and Figure 5 When the pipe fitting needs to be placed and positioned, the pipe fitting is first placed on the mounting bracket 41. Then, the sliding bracket 21 moves under the drive of the sliding assembly 22 and approaches the end of the pipe fitting. When the clamping jaw 242 slides with the sliding bracket 21 and moves to the outside of the pipe fitting, the sliding bracket 21 stops. At this time, the piston rod of the rotating cylinder 261 slides and drives the shift fork ring 262 to slide towards the clamping jaw 242. During this process, the shift fork ring 262 drives the connecting sleeve 263 to slide, so that the connecting sleeve 263 abuts against the guide surface on the clamping jaw 242, thereby pushing the end of the clamping jaw 242 away from the connecting bracket 241 to rotate downward, thereby clamping and fixing the pipe fitting. During this process, the return spring 243 is compressed. Then, the sliding bracket 21 returns to the initial position under the drive of the sliding assembly 22, realizing the positioning of the pipe fitting.

[0047] Reference Figure 1 and Figure 2 The pipe bending seat 31 is rotatably connected to the end of the processing seat 122 away from the main body 11 via a bearing, and the rotation axis of the pipe bending seat 31 is vertically arranged. The pipe bending assembly 33 includes a pipe bending motor 331, the body 1 of the pipe bending motor 331 is fixedly connected to the processing seat 122 by bolts, the output shaft of the pipe bending motor 331 is vertically arranged, and the output shaft of the pipe bending motor 331 drives the pipe bending seat 31 to rotate via a pulley. The method of the pipe bending motor 331 driving the pipe bending seat 31 to rotate via a pulley is prior art, so it will not be described in detail here.

[0048] Reference Figure 2 and Figure 6 A pipe bending frame 34 is also provided on the top of the pipe bending seat 31, and the pipe bending frame 34 is fixedly connected to the pipe bending seat 31 by bolts. The side wall of the pipe bending frame 34 is arc-shaped, and a pipe bending groove 341 is also provided on the side wall of the pipe bending frame 34. A clamping assembly 32 is provided on the pipe bending seat 31. The clamping assembly 32 includes a clamping frame 321, a connecting rod assembly 322, and a driving component 323. The clamping frame 321 is located on the side of the pipe fitting away from the pipe bending frame 34. The connecting rod assembly 322 includes a first rotating rod 3221, a first connecting rod 3222, a second connecting rod 3223, and a second rotating rod 3224. A clamping block 324 is also provided on the side wall of the clamping frame 321 near the pipe bending seat 31. The clamping block 324 is fixedly installed on the clamping frame 321, and the clamping block 324 is at the same height as the pipe bending groove 341.

[0049] Reference Figure 2 and Figure 6 The bottom end of the first rotating rod 3221 is rotatably connected to the bend seat 31 via a pin, and the top end of the first rotating rod 3221 is rotatably connected to the bottom end of the clamping frame 321. The top end of the first connecting rod 3222 is rotatably connected to the clamping frame 321 via a pin, and the rotation axis of the top end of the first connecting rod 3222 is the same as the rotation axis of the top end of the first rotating rod 3221. The bottom end of the first connecting rod 3222 is rotatably connected to the top end of the second connecting rod 3223 via a pin, and the bottom end of the second connecting rod 3223 is rotatably connected to the bottom end of the second rotating rod 3224 via a pin. The top end of the second rotating rod 3224 is rotatably connected to the end of the clamping frame 321 away from the first rotating rod 3221 via a pin.

[0050] Reference Figure 6 The driving component 323 includes a driving cylinder 3231, which is located below the connecting rod assembly 322. The cylinder body of the driving cylinder 3231 is rotatably connected to the bent pipe seat 31 via a bracket and a pin. The piston rod of the driving cylinder 3231 extends upward. The rotatable connection between the first connecting rod 3222 and the second connecting rod 3223 is rotatably connected to the piston rod of the driving cylinder 3231.

[0051] Reference Figure 6 In the initial state, the clamping frame 321 is located on the side of its displacement path away from the pipe bending frame 34. At this time, the piston rod of the drive cylinder 3231 is in a retracted state, and the pipe bending frame 34 is located on the side of the pipe away from the clamping frame 321, and the mounting frame 41 is located on the side of the clamping frame 321 close to the support frame 71.

[0052] Reference Figure 6When bending is required, the processing seat 122 slides under the drive of the adjusting cylinder 6, causing the bending groove 341 on the bending frame 34 to gradually come into contact with the side wall of the pipe. Then, the piston rod of the driving cylinder 3231 extends, thereby causing the rotating connection between the first connecting rod 3222 and the second connecting rod 3223 to move upward. At this time, the first rotating rod 3221 rotates towards the bending frame 34, thereby causing the first rotating rod 3221 to drive the clamping frame 321 to approach the bending frame 34, so that the clamping block 324 on the clamping frame 321 and the bending frame 34 clamp the pipe. At this time, the inner wall of the bending groove 341 and the side wall of the clamping block 324 are both in contact with the side wall of the pipe, thus achieving clamping.

[0053] Reference Figure 6 When clamping is completed, the pipe bending assembly 33 drives the pipe bending seat 31 to rotate. At this time, the pipe bending frame 34 and the clamping frame 321 rotate together with the pipe bending seat 31, so that the clamped end of the pipe is bent along the pipe bending groove 341, thereby realizing the pipe bending process.

[0054] Reference Figure 6 Both the pipe bending frame 34 and the clamping frame 321 are equipped with positioning frames 8. The positioning frames 8 on the pipe bending frame 34 are located directly below the pipe bending groove 341, and the positioning frames 8 on the clamping frame 321 are located directly below the clamping block 324. Each positioning frame 8 has a groove on its side wall near the other positioning frame 8 that fits against the side wall of the pipe fitting. Both positioning frames 8 have through holes 81 at their top and bottom ends, which communicate with the grooves on the corresponding positioning frames 8 to allow waste chips to pass through during punching. The pipe bending seat 31 is also equipped with a waste collection box 9. The upper end of the waste collection box 9 is open and located directly below the waste holes 81 on the pipe bending frame 34, so that the waste generated during punching falls into the waste collection box 9 through the waste holes 81.

[0055] Reference Figure 2 and Figure 6 Before punching the pipe fitting, the clamping frame 321 is positioned away from the bending frame 34, which is located to one side of the pipe fitting. When positioning punching is required, the lifting member 5 drives the processing seat 122 upward, so that the positioning frame 8 on the bending frame 34 is at the same height as the pipe fitting to be processed. Then, the processing seat 122 moves closer to the pipe fitting under the drive of the adjusting cylinder 6, so that the positioning frame 8 on the bending frame 34 is in contact with the side wall of the pipe fitting. Next, the driving member 323 drives the clamping frame 321 closer to the pipe fitting via the connecting rod assembly 322, and the positioning frame 8 on the clamping frame 321 gradually moves closer to the pipe fitting and finally contacts the side wall of the pipe fitting, so that the pipe fitting is clamped and positioned by the action of the two positioning frames 8.

[0056] Reference Figure 1 and Figure 4An end-fixing frame 44 is also provided on the end of the main body 11 away from the processing seat 122. The end-fixing frame 44 is slidably connected to the main body 11 via a slide rail. The sliding direction of the end-fixing frame 44 is the length direction of the main body 11. One end of the mounting bracket 41 is fixedly connected to the end-fixing frame 44. An end-fixing adjustment component 45 is also provided on the main body 11. The end-fixing adjustment component 45 is used to drive the end-fixing frame 44 to slide. Optionally, in this embodiment, the end-fixing adjustment component 45 is a hydraulic cylinder. The hydraulic cylinder is mounted on the main body 11, and the piston rod of the hydraulic cylinder is fixedly connected to the end-fixing frame 44.

[0057] Reference Figure 1 , Figure 3 and Figure 4 The punching assembly 43 includes a drive frame 431 and a displacement member 432. The drive frame 431 is located inside the mounting frame 41 and is slidably connected to the mounting frame 41. One end of the drive frame 431 extends out of the mounting frame 41 away from the processing base 122, and the other end of the drive frame 431 extends to the vicinity of the punching frame 42. A displacement member 46 is also provided on the end fixing frame 44. The displacement member 46 is slidably connected to the end fixing frame 44 via a slide rail, and the sliding direction of the displacement member 46 is the axial direction of the drive frame 431. The end of the drive frame 431 that extends out of the mounting frame 41 is fixedly mounted on the displacement member 46.

[0058] Reference Figure 1 , Figure 3 and Figure 4 Optionally, in this embodiment, the displacement member 432 is a hydraulic cylinder, which is fixedly mounted on the end bracket 44. The piston rod of the hydraulic cylinder is fixedly connected to the displacement bracket 46 by bolts, and the axial direction of the piston rod of the hydraulic cylinder is the sliding direction of the displacement bracket 46. A driving part 4311 is also provided on one end of the drive bracket 431 near the punching bracket 42. The driving part 4311 is integrally formed with the drive bracket 431. One end of the driving part 4311 is inclined and inserted into the punching bracket 42, and is slidably connected to the punching bracket 42. The sliding direction of the punching bracket 42 and the sliding direction of the drive bracket 431 both form an acute angle with the sliding direction of the driving part 4311 relative to the punching bracket 42. The sliding direction of the punching bracket 42 and the mounting bracket 41 is vertical, and the bottom end of the punching bracket 42 can slide out of the mounting bracket 41, thereby punching the pipe fittings sleeved on the mounting bracket 41.

[0059] Reference Figure 1 , Figure 3 and Figure 4In the initial state, the mounting bracket 41 is located near the clamping bracket 321 on the side of the clamping bracket 321 closest to the support bracket 71, and the punching bracket 42 is completely located within the mounting bracket 41. When punching is required on the pipe fitting, the end-fixing bracket 44 is displaced towards the clamping bracket 321 under the drive of the end-fixing adjustment member 45, so that the punching bracket 42 on the mounting bracket 41 corresponds to the discharge hole 81 on the positioning bracket 8. Then, when the displacement member 432 drives the drive bracket 431 to slide towards the processing base 122, the drive part 4311 on the drive bracket 431 slides against the punching bracket 42. At this time, the punching bracket 42 slides downward under the restriction of the mounting bracket 41, so that the bottom end of the punching bracket 42 slides out of the mounting bracket 41, thereby punching the pipe fitting.

[0060] The implementation principle of the pipe bending and punching integrated machine in Embodiment 1 of this application is as follows: During use, the operator first places one end of the pipe fitting onto the mounting frame 41. At this time, the sliding component 22 drives the sliding frame 21 to slide and approach the end of the pipe fitting. When the clamping claw 242 moves to the outside of the pipe fitting, the sliding frame 21 stops. Then, the driving component 26 drives the clamping claw 242 to clamp and fix the pipe fitting, thereby achieving the positioning of the pipe fitting. Then, the support member 72 drives the support frame 71 to rotate, causing the rotating cylinder 73 to abut against the bottom end of the pipe fitting, thus supporting the pipe fitting.

[0061] Then, the adjusting cylinder 6 drives the processing seat 122 to slide, so that the bending groove 341 on the bending frame 34 is in contact with the side wall of the pipe. Then, the clamping frame 321 clamps the pipe under the drive of the driving component 323 and the connecting rod assembly 322. After clamping, the bending assembly 33 drives the bending seat 31 to rotate. At this time, the bending frame 34 and the clamping frame 321 rotate together with the bending seat 31, so that the clamped end of the pipe bends along the bending groove 341, thereby realizing the bending of the pipe.

[0062] After the pipe bending is completed, the drive unit 323 and the connecting rod assembly 322 move the clamping frame 321 away from the pipe bending frame 34. Then, the adjusting cylinder 6 moves the processing seat 122 to slide, causing the pipe bending frame 34 to move away from the pipe. Next, the lifting unit 5 moves the lifting frame 12 up, so that the positioning frame 8 on the pipe bending frame 34 is at the same height as the pipe to be processed. Then, the processing seat 122 moves closer to the pipe, and the clamping frame 321 moves closer to the pipe, so that the pipe is clamped and positioned by the two positioning frames 8. After that, the end fixing frame 44 moves towards the clamping frame 321 under the drive of the end fixing adjusting unit 45, so that the punching frame 42 on the mounting frame 41 corresponds to the discharge hole 81 on the positioning frame 8. At this time, when the displacement member 432 drives the drive frame 431 to slide towards the processing base 122, the drive part 4311 on the drive frame 431 slides with the punching frame 42. At this time, the punching frame 42 slides down under the restriction of the mounting frame 41, so that the bottom end of the punching frame 42 slides out of the mounting frame 41, thereby punching the pipe.

[0063] Example 2: The difference between Embodiment 2 and Embodiment 1 in this application is that: (Refer to...) Figure 7 and Figure 8 The support mechanism 7 also includes a clamping frame 74 and a linkage assembly 75. The top of the clamping frame 74 is located above the pipe fitting, and a rotating cylinder 73 is also provided on the top of the clamping frame 74. The rotating cylinder 73 and the clamping frame 74 are rotatably connected by a pin, and the bottom end of the rotating cylinder 73 abuts against the top of the clamping frame 74. The middle part of the clamping frame 74 is rotatably connected to the body 11 by a bracket and a pin.

[0064] Reference Figure 7 and Figure 8 The linkage assembly 75 includes an intermediate frame 751, a transfer frame 752, and a linkage frame 753. One end of the intermediate frame 751 is rotatably connected to the middle of the support frame 71 via a pin, and the other end of the intermediate frame 751 is rotatably connected to the top of the transfer frame 752 via a pin. The bottom end of the transfer frame 752 is rotatably connected to the main body 11 via a pin. The linkage frame 753 is sleeved on the lower middle part of the clamping frame 74 and is slidably connected to the clamping frame 74. The top of the transfer frame 752 is rotatably connected to the linkage frame 753, and the rotation axis of the transfer frame 752 and the linkage frame 753 is the same as the rotation axis of the transfer frame 752 and the intermediate frame 751.

[0065] Reference Figure 7 and Figure 8Initially, the rotating cylinder 73 on the support frame 71 is located below the pipe fitting, while the rotating cylinder 73 on the clamping frame 74 is located above the pipe fitting. When support is needed for the pipe fitting, the support member 72 drives the top of the support frame 71 to rotate upward. During this process, the intermediate frame 751 is displaced, causing the top of the intermediate frame 752 to rotate upward, which in turn drives the linkage frame 753 to move upward. During this process, the linkage frame 753 slides relative to the clamping frame 74, causing the top of the clamping frame 74 to rotate downward. When the rotating cylinder 73 on the support frame 71 abuts against the bottom end of the pipe fitting, the rotating cylinder 73 on the clamping frame 74 abuts against the top end of the pipe fitting.

[0066] The implementation principle of the pipe bending and punching integrated machine in Embodiment 2 of this application is as follows: When the pipe needs to be supported, the support member 72 drives the top of the support frame 71 to rotate upward. During this process, the intermediate frame 751 is displaced, thereby causing the top of the transfer frame 752 to rotate upward, which in turn drives the linkage frame 753 to move upward. During this process, the linkage frame 753 slides relative to the clamping frame 74, causing the top of the clamping frame 74 to rotate downward. When the rotating cylinder 73 on the support frame 71 abuts against the bottom end of the pipe, the rotating cylinder 73 on the clamping frame 74 abuts against the top end of the pipe.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
