Description

Technical Field

[0001] This application relates to the field of metal pipe processing technology, and in particular to a metal pipe production and cutting equipment. Background Technology

[0002] In the field of metal pipe processing, cutting is the primary and fundamental process, and its quality directly affects the precision of the product and the smoothness of subsequent processes.

[0003] Currently, the mainstream methods for cutting metal pipes are laser cutting and mechanical saw blade cutting. Among them, laser cutting has the advantages of high precision and strong adaptability. However, the purchase cost and application cost of laser cutting equipment are much higher than those of mechanical saw blade cutting equipment. Therefore, mechanical saw blade cutting is more widely used in the field of metal pipe cutting.

[0004] The essence of mechanical saw blade cutting is to use high-speed moving saw teeth to exert strong mechanical action on metal materials, separating the materials through tearing and grinding. This process will generate forces in several directions on the pipe fitting, such as downward pressure and cutting force, as well as unavoidable vibrations generated by the operation of the equipment and the cutting process itself.

[0005] For thick-walled pipes, their inherent structural rigidity is sufficient to resist these external forces without significant deformation. However, for thin-walled pipes, due to their thinner walls and weaker structural rigidity, they are prone to plastic deformation under the combined action of the above forces, thus limiting the applicability of such mechanical saw blade cutting equipment. Summary of the Invention

One of the support plates is rotatably connected to the rod body, and the other support plate is slidably connected to the rod body. The guide rail is mounted on the frame, and the bottom of the other support plate is slidably connected to the guide rail. The fixing plate is mounted on the support plate, and the locking knob is located between the fixing plate and the guide rail. One end of the metal pipe to be cut abuts against the other support plate.

[0012] Furthermore, the feeding mechanism includes a base, a plurality of first rollers, a first hydraulic telescopic rod, and two guide rods. The base is located above the frame, and the plurality of first rollers are rotatably mounted on the base.

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0020] The metal pipe fitting production and cutting equipment of this application embodiment is described below with reference to the accompanying drawings.

[0021] like Figures 1-6 As shown, the metal pipe production and cutting equipment of this application embodiment may include: a frame 1, a feeding mechanism 2, a support mechanism 3, a cutting mechanism 4, and two rotary drive mechanisms 5.

[0022] The feeding mechanism 2 is mounted on the frame 1 and is used to move the metal pipe to be cut toward the support mechanism 3.

[0023] One end of the support mechanism 3 extends into the interior of the metal pipe to be cut. The support mechanism 3 includes two support plates 31, a rod 32, a support assembly 33, a connecting assembly 34, and a driving component 35.

[0024] Two support plates 31 are mounted on the frame 1, and the rod 32 is movably connected to the support plates 31.

[0025] In the above embodiment, the rod 32 and the support plate 31 are rotatably connected by a bearing, and the support plate 31 is used to support and fix the rod 32.

[0026] The support component 33 is hexagonal in shape and is movably connected to the rod 32. The support component 33 abuts against the inner wall of the metal pipe to be cut. The support component 33 is provided with a gap 335, which is used to provide a space for the saw blade of the cutting mechanism 4 to avoid interference between the saw blade of the cutting mechanism 4 and the support component 33.

[0027] The connecting component 34 is fixedly connected to the support component 33 and slidably connected to the support plate 31. The connecting component 34 is used to limit the support component 33 to ensure that the support component 33 can only move along the rod 32 and cannot rotate.

[0028] The drive component 35 is disposed between the rod 32 and the frame 1. The drive component 35 is used to drive the rod 32 to rotate, so as to drive the support assembly 33 to deform.

[0029] It should be noted that the specific structure and working principle of the driving component 35 described in this embodiment have been disclosed in the prior art, so they will not be described in detail here.

[0030] The cutting mechanism 4 is mounted on the frame 1. The saw blade of the cutting mechanism 4 is close to the gap 335 and is arranged directly opposite it. The cutting mechanism 4 includes multiple drive units, protective covers and saw blades. Its specific connection structure and working principle have been disclosed in the prior art, so they will not be described in detail here.

[0031] Two rotary drive mechanisms 5 are symmetrically arranged on the frame 1. The rotary drive mechanisms 5 abut against the outer wall of the metal pipe and are used to drive the metal pipe to rotate at a constant speed to change the cutting position on the metal pipe.

[0032] The feeding mechanism 2, the support mechanism 3, and the two rotary drive mechanisms 5 are arranged along the axis of the metal tube to be cut.

[0033] In the embodiments of this application, a control device is provided on the frame 1. The feeding mechanism 2, the support mechanism 3, the cutting mechanism 4 and the rotary drive mechanism 5 are respectively connected to the control device (not shown in the figure). The control device may include a control panel, which is provided with a display screen and function buttons, so that relevant personnel can view the data of the metal pipe production and cutting equipment during operation through the display screen, and can easily adjust and modify the data by inputting the buttons.

[0034] Specifically, relevant technicians use this metal pipe production and cutting equipment to cut thin-walled metal pipes. In the initial state, the saw blade of the cutting mechanism 4 and the two rotary drive mechanisms 5 are far away from the metal pipe.

[0035] The relevant technicians place the metal pipe to be cut on the feeding mechanism 2. The feeding mechanism 2 is raised to a certain height (this working condition can be obtained by the position sensor). It should be noted that after the feeding mechanism 2 raises the metal pipe, the metal pipe is placed coaxially with the rod 32.

[0036] Push the metal pipe to be cut so that one end of the support mechanism 3 is placed inside the metal pipe to be cut, and the cutting position of the metal pipe to be cut is directly opposite the saw blade of the cutting mechanism 4.

[0037] The control device sends an operation signal to the drive component 35, which drives the rod 32 to rotate. Under the constraint of the connecting component 34, the hexagonal support component 33 deforms along the direction of the rod 32. The support component 33 abuts against the inner wall of the metal pipe to be cut, and the gap 335 on the support component 33 is directly opposite the cutting position.

[0038] In the above embodiment, a certain force is maintained between the support component 33 and the metal pipe to be cut (this working condition can be obtained by arranging the first pressure sensor), so as to avoid damage to the support mechanism 3 while ensuring the support effect.

[0039] Next, the control device sends a running signal to the rotary drive mechanism 5, which then abuts against the outer wall of the metal pipe to be cut, maintaining a certain force between them (this condition can be obtained by arranging a second pressure sensor). This ensures the clamping effect while preventing damage to the rotary drive mechanism 5 or deformation of the metal pipe.

[0040] Then, the feed mechanism 2 resets, the cutting mechanism 4 runs, and the saw blade of the cutting mechanism 4 cuts the outer wall of the metal pipe. The rotary drive mechanism 5 drives the metal pipe to rotate slowly, and the saw blade of the cutting mechanism 4 cuts along the cross-section of the metal pipe. During the cutting process, the support component 33 is relatively stationary with respect to the saw blade of the cutting mechanism 4, thereby providing real-time support to the area near the cutting position to resist the external force brought by the cutting process. This makes it less likely for the thin-walled metal pipe to deform, expands the applicability of the equipment, and avoids the need for subsequent straightening of the metal pipe.

[0041] After the rotary drive mechanism 5 drives the metal pipe to rotate once, the metal pipe is cut. The feed mechanism 2 rises, the rotary drive mechanism 5 resets, and the relevant technicians pull the remaining metal pipe away from the support mechanism 3 to prepare for unloading.

[0042] After the support component 33 is reset, the worker can remove the cut metal pipe and repeat the above steps to obtain multiple target metal pipes.

[0043] In the embodiments of this application, the feeding mechanism 2 and the rotary drive mechanism 5 serve to support the metal pipe. During the entire processing of the metal pipe, the support mechanism 3 only applies a vertical force to the cross-sectional direction of the metal pipe and does not bear the weight of the metal pipe. Therefore, the support mechanism 3 can be used reasonably and for a long time.

[0044] In addition, when using this equipment to cut thick metal pipes, repeat the above steps. The support mechanism 3 can be placed at the end of the metal pipe to help balance the force on the metal pipe during the cutting process. Alternatively, the support mechanism 3 can be removed from the equipment to facilitate unloading, thus expanding the applicability of this equipment.

[0045] In one embodiment of this application, such as Figure 3 and Figure 4 As shown, the support assembly 33 includes a support member 331, multiple rollers 332, two hinged drive members 333, and two threaded sleeves 334.

[0046] The support member 331 is X-shaped and sleeved on the outside of the rod 32. Multiple rollers 332 are rotatably connected to the support member 331. The rollers 332 abut against the inner wall of the metal tube to be cut. A gap 335 is arranged between two rollers 332. Two hinged drive members 333 are symmetrically pivotally connected to both sides of the support member 331. Two threaded sleeves 334 are pivotally connected to the corresponding hinged drive members 333. The rod 32 has two threads with opposite directions of rotation. The two threaded sleeves 334 are connected to the corresponding threads.

[0047] It is understandable that the support member 331 is sleeved on the outside of the rod 32 in an X-shaped structure, and there are four rollers 332, which are located at the four corners of the support member 331. Their X-shaped arrangement can ensure that the force between each roller 332 and the metal pipe is the same.

[0048] In one embodiment of this application, such as Figure 3 As shown, the connecting assembly 34 includes two ear plates 341 and an auxiliary rod 342.

[0049] Two ear plates 341 are respectively installed on the corresponding threaded sleeves 334.

[0050] The support component 33 is arranged at an angle.

[0051] Understandably, the inclined arrangement of the support component 33 can avoid interference between it and the auxiliary rod 342, thus ensuring the normal operation of the support mechanism 3.

[0052] The auxiliary rod 342 passes through the two ear plates 341. One ear plate 341 is fixedly connected to the auxiliary rod 342, and the other ear plate 341 is slidably connected to the auxiliary rod 342.

[0053] The auxiliary rod 342 passes through a support plate 31 and is slidably connected to it. Another support plate 31 has a through hole 343, which is arranged opposite to the auxiliary rod 342.

[0054] Specifically, when the support mechanism 3 is running, the control device sends a signal to the drive component 35, and the drive component 35 drives the rod 32 to rotate. Since the threaded sleeve 334 is threadedly connected to the rod 32, the two ends of the support assembly 33 move towards each other. Under the action of the hinged drive component 333 and the support component 331, the roller 332 abuts against the inner wall of the metal pipe, and the gap 335 between the two rollers 332 is directly opposite the saw blade.

[0055] During the movement of the threaded sleeve 334, one lug 341 drives the auxiliary rod 342 to move. The auxiliary rod 342 is slidably connected to a support plate 31, and the other lug 341 slides on the auxiliary rod 342. The auxiliary rod 342 and the lug 341 can play a limiting role, ensuring that the threaded sleeve 334 can only move along the rod 32.

[0056] In one embodiment of this application, such as Figure 2 and Figure 3 As shown, the support mechanism 3 also includes an adjustment component 36, which includes a guide rail 361, a fixing plate 362, and a locking knob 363.

[0057] One support plate 31 is rotatably connected to the rod 32, and the other support plate 31 is slidably connected to the rod 32. The guide rail 361 is set on the frame 1. The bottom of the other support plate 31 is slidably connected to the guide rail 361. The fixing plate 362 is set on the support plate 31. The locking knob 363 is set between the fixing plate 362 and the guide rail 361. One end of the metal pipe to be cut abuts against the other support plate 31.

[0058] It should be noted that, in this embodiment, one end of the metal pipe to be cut abuts against another support plate 31, which enables the metal pipe to be cut to a fixed length.

[0059] Specifically, by rotating the locking knob 363, the position of the other support plate 31 can be changed, and the other support plate 31 can be pushed. The bottom of the support plate 31 slides on the guide rail 361, and the rod 32 slides relative to the other support plate 31, thereby enabling the acquisition of metal pipes of more specifications and lengths, further expanding the applicability of this equipment.

[0060] In one embodiment of this application, such as Figure 2 and Figure 5 As shown, the feeding mechanism 2 includes a base 21, multiple first rollers 22, a first hydraulic telescopic rod 23, and two guide rods 24.

[0061] The base 21 is located above the frame 1. Multiple first rollers 22 are rotatably mounted on the base 21. A first hydraulic telescopic rod 23 is mounted on the frame 1. The output end of the first hydraulic telescopic rod 23 is connected to the base 21. Two guide rods 24 are located at opposite corners of the base 21. The guide rods 24 penetrate the upper surface of the frame 1 and are slidably connected to it.

[0062] Specifically, during the operation of the feeding mechanism 2, the first hydraulic telescopic rod 23 pushes the base 21 to move. At the same time, the guide rod 24 is slidably connected to the frame 1, thereby guiding the base 21 and ensuring the stability of the base 21's movement. When relevant technicians push or pull the metal pipe, the metal pipe moves on multiple first rollers 22 to reduce the friction between them and facilitate the movement of the metal pipe.

[0063] In one embodiment of this application, such as Figure 2 and Figure 6 As shown, the rotary drive mechanism 5 includes a bracket 51, a first connecting frame 52, a second connecting frame 53, two second hydraulic telescopic rods 54, a drive motor 56, and two second rollers 55.

[0064] The bracket 51 is connected to the frame 1, the first connecting frame 52 is pivotally connected to the bracket 51, the second connecting frame 53 is pivotally connected to the first connecting frame 52, a second hydraulic telescopic rod 54 is disposed between the bracket 51 and the first connecting frame 52, another second hydraulic telescopic rod 54 is disposed between the first connecting frame 52 and the second connecting frame 53, two second roller shafts 55 are respectively rotatably disposed on the first connecting frame 52 and the second connecting frame 53 and abut against the outer wall of the metal pipe to be cut, and a drive motor 56 is disposed on the second connecting frame 53, the output shaft of the drive motor 56 is connected to one end of a second roller shaft 55.

[0065] Specifically, during the operation of the rotary drive mechanism 5, a second hydraulic telescopic rod 54 operates, thereby pushing a second roller 55 on the first connecting frame 52 to abut against the outer wall of the metal pipe. Subsequently, another second hydraulic telescopic rod 54 operates, thereby pushing another second roller 55 on the second connecting frame 53 to abut against the outer wall of the metal pipe to support the entire metal pipe.

[0066] The drive motor 56 drives a second roller shaft 55 to rotate, so that the metal tube can rotate slowly and uniformly, thereby continuously changing the cutting position.

[0067] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, a coolant treatment tank 61 and a collection tank 62 are provided on the frame 1.

[0068] The collection tank 62 is connected to the coolant treatment tank 61. The collection tank 62 is located below the support mechanism 3. The outlet of the coolant treatment tank 61 is connected to a pipe, and one end of the pipe extends to the saw blade of the cutting mechanism 4.

[0069] It should be noted that the coolant treatment tank 61 described in this embodiment can filter the coolant, making it reusable, thereby saving costs. The specific structure of the connection between the coolant treatment tank 61, the collection tank 62 and the pipe body has been disclosed in the prior art, so it will not be described in detail here.

[0070] It is understandable that the above structure can play a role in cooling, lubrication, cleaning and rust prevention during the cutting of metal pipes.

[0071] In summary, the metal pipe production and cutting equipment of this application embodiment drives the rod to rotate through the driving component, the rod drives the support component to deform, the support component abuts against the inner wall of the metal pipe, the gap on the support component provides a space for the saw blade to accommodate, avoiding interference between the two, the rotation drive mechanism drives the metal pipe to rotate at a uniform speed, the support component and the saw blade of the cutting mechanism are relatively stationary, thereby providing real-time support for the area near the cutting position to resist the external force brought by the cutting process, making the thin-walled metal pipe less prone to deformation; In addition, when using this equipment to process thick metal pipes, the support mechanism can also act on one end of the metal pipe to balance the force on the metal pipe during the cutting process, thereby expanding the applicability of this equipment.
