Description

Technical Field

[0001] This utility model relates to the field of profile cutting technology, and in particular to a material protection device for a profile cutting machine and a profile cutting machine including the device. Background Technology

[0002] A cutting machine includes a movable material guard device. This device comprises a driven assembly for material guarding and two material guarding arms, the drive assembly of which can move the two arms closer together or further apart. Each arm has material guarding blocks. When the profile needs to be cut with rotation, the two blocks are positioned as close to the profile as possible without contacting it, thus limiting profile movement and ensuring cutting quality. When the profile needs to be pulled out, the drive assembly moves the blocks on the two arms to clamp the profile, and then the device is moved to pull the profile out.

[0003] However, in actual cutting operations, there is also a process of axial movement of the profile. The material guard device of the aforementioned cutting machine cannot contact the profile during axial movement, causing the end of the profile to wobble up and down. Therefore, the cutting effect of the machine still cannot meet the manufacturer's higher quality requirements. Utility Model Content

[0004] The main purpose of this utility model is to propose a material protection device, which aims to solve the technical problem in the prior art where the profile moves up and down during cutting, resulting in poor cutting quality.

[0005] To achieve the above objectives, this utility model proposes a material protection device for a profile cutting machine, including a material protection mounting plate and a material protection drive assembly and two material protection arms connected thereon. The two material protection arms are arranged opposite to each other, and the material protection drive assembly can drive the two material protection arms to move closer or further apart from each other. A roller structure is provided on the side of the material protection arm closest to the other material protection arm. The roller structures on the two material protection arms are positioned correspondingly and their rotation axes extend vertically. When the profile on the profile cutting machine is cut along its axial direction, the two roller structures can clamp the profile and move relative to it along its axial direction.

[0006] The beneficial effects of this utility model are as follows: When the material guarding device of this utility model is used to cut the profile axially, the roller structure on the two material guarding arms can not only clamp the profile and position it to prevent it from swaying left and right, but also move relative to the profile along the axial direction. It can keep the profile clamped and positioned during the axial cutting of the profile, which is conducive to improving the quality of profile cutting, especially the quality of axial cutting.

[0007] Preferably, the roller structure includes a roller assembly, which includes multiple sub-rollers. The multiple sub-rollers in the same roller assembly are coaxially arranged and arranged along the rotation axis of the roller assembly. An annular groove is formed between adjacent sub-rollers, which is beneficial for correcting the pipe and improving the cutting quality.

[0008] Preferably, the roller structure on each guard arm includes at least two roller assemblies, which are arranged horizontally. The two roller assemblies on one guard arm correspond one-to-one with the two roller assemblies on the other guard arm, so that the projection of the profile on the horizontal plane can be kept as straight as possible, thereby ensuring or even improving the profile cutting quality.

[0009] Preferably, the material guard arm is equipped with a clamping drive device and a clamping component connected by a transmission. The clamping component is located on the side of the material guard arm close to the other material guard arm. The clamping drive device can drive the clamping component away from or close to the other material guard arm. The clamping components on the two material guard arms are in corresponding positions and are used to clamp the profile. This helps to make the profile cutting machine have a compact structure and also helps to reduce the manufacturing cost of the profile cutting machine.

[0010] Preferably, the clamping component has a clamping surface located on the side of the clamping component away from the guard arm it is on. The two clamping surfaces are arranged opposite each other. The clamping surfaces are provided with multiple protrusions, which are arranged in the vertical direction and spaced apart in sequence. This can more accurately move the profile axially to the target position, thereby improving the cutting accuracy.

[0011] Preferably, the material guard arm is provided with an installation clearance hole, and the clamping drive device includes a clamping cylinder. The piston rod of the clamping cylinder passes through the installation clearance hole and is connected to the clamping component. A protective component is provided on the side of the material guard arm near the clamping component. The protective component includes an upper protective part located above the installation clearance hole and two side protective parts respectively located on both sides of the installation clearance hole. The two ends of the upper protective part are respectively connected to the upper ends of the two side protective parts. When the clamping component is close to the material guard arm, the protective component is located outside the clamping component, which helps to block the flying debris during cutting, thereby ensuring the normal operation of the clamping drive device.

[0012] Preferably, the material protection drive assembly includes a material protection drive device disposed on the upper side of the material protection mounting plate. The material protection mounting plate is provided with a drive clearance hole. The material protection arm is disposed on the lower side of the material protection mounting plate. One of the material protection arms is connected to the material protection drive device via a connector. The connector passes through the drive clearance hole. A synchronous gear is rotatably connected to the lower side of the material protection mounting plate. Both material protection arms are provided with a transmission rack. Both transmission racks are meshed with the synchronous gear so that the two material protection arms move closer or further away from each other synchronously, making the layout of the profile cutting machine more convenient and compact.

[0013] This utility model also discloses a profile cutting machine, including the material protection device of the above-mentioned profile cutting machine.

[0014] Preferably, the profile cutting machine also includes a frame, on which a front chuck, a cutting device and a material guard mounting plate are arranged in sequence. One end of the material guard arm is connected to the material guard mounting plate, and the other end extends to the underside of the cutting head of the cutting device.

[0015] Preferably, the profile cutting machine further includes a movable pallet and a material support device. The cutting device, the material support plate, and the material support device are sequentially arranged on the movable pallet. The movable pallet is movably mounted on the frame and can be moved away from or close to the front chuck. Attached Figure Description

[0023] like Figures 1 to 4 As shown, a material protection device for a profile cutting machine includes a material protection mounting plate 1 and a material protection drive assembly 2 and two material protection arms 3 connected thereon. The two material protection arms 3 are arranged opposite to each other, and the material protection drive assembly 2 can drive the two material protection arms 3 to move closer to each other or further away from each other. A roller structure 4 is provided on the side of the material protection arm 3 closest to the other material protection arm 3. The roller structures 4 on the two material protection arms 3 are positioned correspondingly and their rotation axes extend vertically. When the profile on the profile cutting machine is cut along its axial direction, the two roller structures 4 can clamp the profile and move relative to it along its axial direction.

[0024] In this embodiment, when the profile is being cut axially, the roller structure 4 on the two guard arms 3 can not only clamp the profile and position it to prevent it from swaying left and right, but also move relative to the profile along the axial direction. This allows the profile to be clamped and positioned continuously during axial cutting, which helps to improve the quality of profile cutting, especially the quality of axial cutting.

[0025] In this embodiment, the "axial direction of the profile" refers to the theoretical axial extension direction 'a' of the profile when it is placed on the profile cutting machine. Generally, this direction is horizontal. In actual operation, the ends of the profile will sag downwards due to gravity, causing the profile to bend to a certain extent. Therefore, when the profile is actually placed on the profile cutting machine, its axis is curved, which may differ from the "axial direction of the profile" referred to in this embodiment. Nevertheless, to prevent further deformation of the profile, the roller structure 4 must also move along the theoretical axial direction of the profile, thereby stabilizing the position of the profile and preventing further bending, thus ensuring cutting quality.

[0026] In some specific embodiments, reference is made to Figure 3 The roller structure 4 includes a roller assembly 41, which includes multiple sub-rollers 411. The multiple sub-rollers 411 in the same roller assembly 41 are coaxially arranged and arranged along the rotation axis of the roller assembly 41. An annular groove 412 is formed between adjacent sub-rollers 411.

[0027] Specifically, the roller structure 4 is provided on two roller mounting plates arranged at intervals in the vertical direction on the material guard arm 3. The roller assembly 41 is located between the two roller mounting plates, and the two roller mounting plates restrict the multiple sub-rollers 411 from spreading out, so that adjacent sub-rollers 411 are in close contact with each other.

[0028] The peripheral sidewall and the upper sidewall, as well as the peripheral sidewall and the lower sidewall, of the dividing roller 411 are provided with transitional annular arc surfaces. Taking two adjacent dividing rollers 411 as an example, the dividing roller 411 located on the upper side is called the upper dividing roller 411, and the dividing roller 411 located on the lower side is called the lower dividing roller 411. The transitional annular arc surface on the lower side of the upper dividing roller 411 and the transitional annular arc surface on the upper side of the lower dividing roller 411 enclose the aforementioned annular groove 412.

[0029] When the two roller structures 4 clamp the profile, especially the tube, the annular groove 412 causes a slight deformation of the tube. As the roller structure 4 moves relative to the tube, it also rotates. Therefore, the annular groove 412 constantly presses against the tube, causing slight deformation. Furthermore, as the roller structure 4 gradually approaches the end of the tube, for lighter tubes, the annular groove 412 corrects the tube's shape, making its actual axis increasingly closer to its theoretical horizontal axis, thereby improving the cutting quality.

[0030] In some specific embodiments, references Figure 3 Each material protection arm 3 has a roller structure 4 including at least two roller assemblies 41, which are arranged in a horizontal direction. The two roller assemblies 41 on one material protection arm 3 correspond one-to-one with the two roller assemblies 41 on the other material protection arm 3.

[0031] Each roller structure 4 on the guard arm 3 includes at least two roller assemblies 41, and the two roller assemblies 41 on one guard arm 3 correspond one-to-one with the two roller assemblies 41 on the other guard arm 3. This arrangement allows the projection of the profile on the horizontal plane to maintain a straight extension to the maximum extent, thereby ensuring or even improving the profile cutting quality.

[0032] In some specific embodiments, reference is made to Figure 1 and Figure 4 The material-protecting arm 3 is equipped with a clamping drive device 51 and a clamping component 52 connected by a transmission. The clamping component 52 is located on the side of the material-protecting arm 3 closer to the other material-protecting arm 3. The clamping drive device 51 can drive the clamping component 52 away from or closer to the other material-protecting arm 3. The clamping components 52 on the two material-protecting arms 3 are in corresponding positions and are used to clamp the profile.

[0033] Specifically, the material protection device also includes a clamping drive device 51 and a clamping component 52 mounted on the material protection arm 3. During processing, after a portion of the profile has been processed, the clamping drive device 51 and the clamping component 52 pull the profile out, and then processing continues on the unprocessed portion. The clamping drive device 51 and the clamping component 52 enable the material protection device to not only protect the material but also pull out and position the profile, making it an integrated unit with multiple functions. This contributes to a compact structure for the profile cutting machine and reduces its manufacturing cost.

[0034] In some specific embodiments, reference is made to Figure 1 and Figure 4 The clamping component 52 is provided with a clamping surface 521. The clamping surface 521 is located on the side of the clamping component 52 away from the material guard arm 3 where it is located. The two clamping surfaces 521 are arranged opposite to each other. The clamping surface 521 is provided with a plurality of protrusions 5211. The plurality of protrusions 5211 are arranged in the vertical direction and are arranged in sequence at intervals.

[0035] Multiple vertically extending protrusions 5211 are arranged at intervals on the clamping surface 521. This helps to increase the friction between the clamping member 52 and the profile when the clamping member 52 clamps the profile and moves the profile axially. This allows the clamping member 52 to move the profile axially to the target position more accurately, thereby improving the cutting accuracy.

[0036] During material transfer, the clamping drive device 51 drives the clamping component 52 to move, so that the clamping surface 521 protrudes from the inner side of the roller structure 4, ensuring that the profile is clamped by the two clamping components 52 instead of by the two roller structures 4, thereby smoothly driving the profile to move axially.

[0037] In some specific embodiments, reference is made to Figure 4The material protection arm 3 is provided with an installation clearance hole 31. The clamping drive device 51 includes a clamping cylinder 511. The piston rod of the clamping cylinder 511 passes through the installation clearance hole 31 and is connected to the clamping component 52. The material protection arm 3 is provided with a protective component 6 on the side near the clamping component 52. The protective component 6 includes an upper protective part 61 located above the installation clearance hole 31 and two side protective parts 62 respectively located on both sides of the installation clearance hole 31. The two ends of the upper protective part 61 are respectively connected to the upper ends of the two side protective parts 62. When the clamping component 52 approaches the material protection arm 3 where it is located, the protective component 6 is located outside the clamping component 52.

[0038] Specifically, in order to protect the clamping component 52, in this embodiment, even if the piston rod of the clamping cylinder 511 has been fully retracted, there is still a distance between the clamping component 52 and the protective arm 3. This arrangement helps to avoid collision between the clamping component 52 and the protective arm 3 and helps to extend the service life of the clamping component 52 and the protective arm 3.

[0039] Because there is a distance between the clamping component 52 and the protective arm 3, debris may enter between them during profile cutting, potentially entering the mounting clearance hole 31. This could obstruct the movement of the piston rod of the clamping cylinder 511 and cause abnormal noise. Therefore, in this embodiment, a protective component 6 is provided to prevent flying debris during cutting, thereby ensuring the normal operation of the clamping drive device 51.

[0040] When the piston rod of the clamping cylinder 511 is fully retracted, the inner side of the roller structure 4 protrudes from the clamping surface 521 of the clamping member 52.

[0041] In some specific embodiments, reference is made to Figure 1 and Figure 2 The material protection drive assembly 2 includes a material protection drive device 21 located on the upper side of the material protection mounting plate 1. The material protection mounting plate 1 is provided with a drive clearance hole 11. The material protection arm 3 is located on the lower side of the material protection mounting plate 1. One of the material protection arms 3 is connected to the material protection drive device 21 via a connector 22. The connector 22 passes through the drive clearance hole 11. A synchronous gear 24 is rotatably connected to the lower side of the material protection mounting plate 1. Both material protection arms 3 are provided with a transmission rack 23. Both transmission racks 23 are meshed with the synchronous gear 24 so that the two material protection arms 3 move closer or further away from each other synchronously.

[0042] Specifically, the material protection drive device 21 includes a material protection drive cylinder 211. In this embodiment, the material protection drive device 21 is set on the upper side of the material protection mounting plate 1, which can reduce the length of the material protection device. Moreover, the material protection drive device 21 will not interfere with the position of the material support device 40 or other devices located on the front side, making the layout of the profile cutting machine more convenient and compact. It also helps to reduce the length of the profile cutting machine, reduce the space it occupies, and facilitate transportation and installation.

[0043] This embodiment also discloses a profile cutting machine, see reference. Figure 5 This includes the material protection device for the aforementioned profile cutting machine.

[0044] In some specific embodiments, reference is made to Figure 5 The profile cutting machine also includes a frame 10, on which a front chuck 20, a cutting device 30 and a material protection mounting plate 1 are arranged in sequence. One end of the material protection arm 3 is connected to the material protection mounting plate 1, and the other end extends to the lower side of the cutting head of the cutting device 30.

[0045] Specifically, the roller structure 4 on the material guard arm 3 is located on the side of the cutting head away from the front chuck 20. The front and rear limiting of the roller structure 4 and the front chuck 20 makes the profile position between the roller structure 4 and the front chuck 20 more stable, resulting in a better cutting effect.

[0046] In some specific embodiments, reference is made to Figure 5 The profile cutting machine also includes a movable pallet and a material support device 40. The cutting device 30, the material support mounting plate 1 and the material support device 40 are sequentially arranged on the movable pallet. The movable pallet is movably mounted on the frame 10 and can be moved away from or close to the front chuck 20.

[0047] The material support device 40 is used to receive the profiles cut by the cutting device 30, preventing them from directly hitting the unloading position of the frame 10, thus protecting the profiles and the frame 10. The working process of the movable pallet, the cutting device 30 mounted on it, the material protection mounting plate 1, and the material support device 40 is illustrated below with an example: When circumferential cutting of the profile is required, the front chuck 20 drives the profile to rotate. At this time, the material protection drive device 21 drives the two material protection arms 3 to move closer to each other but not to contact the profile, so as to avoid excessive shaking of the profile. When axial cutting of the profile is required, the material protection drive device 21 drives the two material protection arms 3 to move closer to each other, so that the two roller structures 4 clamp the profile, the moving support plate moves along the axial direction of the profile, the cutting device 30 cuts the profile axially, and at the same time the rollers also roll forward relative to the profile. After the previous section of profile is cut, the material protection drive device 21 drives the two material protection arms 3 to move away from each other, the roller structure 4 disengages from the profile, the moving pallet moves towards the front chuck 20, the clamping drive device 51 drives the clamping parts 52 to move, the two clamping parts 52 clamp the profile, the front chuck 20 temporarily releases the profile, and then the moving pallet moves away from the front chuck 20 to pull the profile out of the front chuck 20 to the target position. Then the front chuck 20 clamps the profile, ready to cut the next section of profile.

[0048] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
