Description

Technical Field

[0001] This application relates to the technical field of aluminum profile processing, and particularly to a double-traction circulation auxiliary device. Background Art

[0002] Profile processing equipment has a wide range of applications in industrial production, especially in fields such as construction, automotive, and aerospace. With the development of automation technology, the conveying and cutting processes of profiles are gradually moving towards high efficiency and precision.

[0003] Currently, in the related art, to achieve efficient conveying and precise cutting of profiles, a single traction mechanism is usually used in cooperation with a fixed clamping device to complete the conveying and positioning of profiles, and then the cutting is performed by a fixedly arranged cutting mechanism.

[0004] However, in the above conventional method, during the cutting process, since there is a certain speed when the traction mechanism approaches the cutting mechanism, for the fixedly arranged cutting mechanism, it is difficult for the traction mechanism to achieve reliable and rapid stopping for cutting. The coordination between the traction mechanism and the cutting mechanism is insufficient, which easily causes accidental displacement or deformation of the profile near the cutting point, thereby affecting the cutting accuracy.

[0005] In the above related art, there is a defect of insufficient profile cutting accuracy. Summary of the Invention

[0006] In order to improve the problem of insufficient profile cutting accuracy, this application provides a double-traction circulation auxiliary device.

[0007] The double-traction circulation auxiliary device provided by this application adopts the following technical solutions: A double-traction circulation auxiliary device includes: a conveying mechanism for conveying profiles; a cutting mechanism disposed on one side of the conveying mechanism for cutting profiles; a first traction mechanism and a second traction mechanism, both of which are disposed on the other side of the conveying mechanism and reciprocate. The first traction mechanism and the second traction mechanism are both used to clamp and traction profiles, and the first traction mechanism and the second traction mechanism alternately traction; a buffer mechanism including a first buffer component and a second buffer component. The first buffer component is disposed on the cutting mechanism, and the second buffer component is provided on both the first traction mechanism and the second traction mechanism. When the first traction mechanism and the second traction mechanism approach the cutting mechanism, the first buffer component and the second buffer component cooperate with each other, so that the first traction mechanism and the second traction mechanism are subjected to resistance at a preset distance from the cutting mechanism and clamp the profiles.

[0008] By adopting the above technical solution, efficient conveying, precise cutting and stable traction of profiles are achieved. The conveying mechanism can smoothly convey the profiles to ensure the continuity of the processing process; the cutting mechanism is arranged on one side of the conveying mechanism, which is convenient for precise cutting of the profiles; the first traction mechanism and the second traction mechanism alternately pull the profiles, which improves the work efficiency; the buffer mechanism provides resistance when the first traction mechanism and the second traction mechanism approach the cutting mechanism through the cooperation of the first buffer component and the second buffer component, thereby ensuring that the profile is further firmly clamped before cutting, effectively improving the cutting accuracy and safety.

[0009] Optionally, the cutting mechanism includes a cutting support, a cutting drive, a cutting screw, a cutting guide, a cutting slide and a cutting assembly for cutting profiles, one end of the cutting support is arranged on one side of the conveying mechanism, the cutting drive, the cutting screw and the cutting guide are all arranged on the cutting support, the cutting screw is parallel to the cutting guide, the cutting slide is screwed to the cutting screw, and the cutting slide is slidably connected to the cutting guide, and the cutting assembly is arranged on the cutting slide, so that the cutting assembly moves back and forth along a cutting direction perpendicular to the profile conveying direction.

[0010] By adopting the above technical solution, the cutting mechanism can achieve precise cutting of the profile. Specifically, the cutting support provides a stable installation foundation for the entire cutting mechanism, and the cutting drive drives the cutting screw to rotate, and cooperates with the guiding function of the cutting guide, so that the cutting slide can move stably along the cutting direction, thereby driving the cutting assembly to achieve precise cutting of the profile, effectively improving the stability and accuracy of the cutting process, and ensuring the smoothness of the cutting action.

[0011] Optionally, the first traction mechanism includes a first driving assembly, a first traction slider, a first rotating member, a first telescopic member, a first extension member, a first bearing plate and a first clamping assembly, the first driving assembly is arranged on one side of the conveying mechanism, the first traction slider is transmission-connected to the first driving assembly, so that the first traction slider moves back and forth along the profile conveying direction, the fixed end of the first rotating member is arranged on the first traction slider, the fixed end of the first telescopic member is arranged at the rotating end of the first rotating member, the telescopic end of the first telescopic member extends vertically and is connected to the first end of the first extension member extending horizontally, the second end of the first extension member is connected to the first clamping assembly, the first end of the first bearing plate is connected to the rotating end of the first rotating member, the second end of the first bearing plate is located below the first clamping assembly, and the first clamping assembly cooperates with the first bearing plate to clamp the profile.

[0012] By adopting the above technical solution, the first traction mechanism can achieve stable clamping and precise traction of the profile. The first driving component drives the first traction slider to move back and forth along the profile conveying direction to provide power for the profile conveying; the cooperation between the first rotating member and the first telescopic member enables the first clamping component to flexibly adjust its position to ensure the accuracy of the clamping operation; the first bearing plate and the first clamping component cooperate with each other to form a stable clamping structure, effectively preventing the profile from deflecting or sliding during the conveying process; the first rotating member can drive the first bearing plate and the first clamping component to rotate, thereby avoiding the second traction mechanism on the return journey.

[0013] Optionally, the second traction mechanism includes a second driving assembly, a second traction slider, a second rotating member, a second telescopic member, a second elongated member, a second bearing plate and a second clamping assembly, the second driving assembly is arranged on a side of the first driving assembly away from the conveying mechanism, the second traction slider is transmission-connected to the second driving assembly, so that the second traction slider moves back and forth along the profile conveying direction, the fixed end of the second rotating member is arranged on the second traction slider, the fixed end of the second telescopic member is arranged on the rotating end of the second rotating member, the telescopic end of the second telescopic member extends vertically and is connected to the first end of the second elongated member extending horizontally, the second end of the second elongated member is connected to the second clamping assembly, the length of the second elongated member is greater than the length of the first elongated member, the first end of the second bearing plate is connected to the rotating end of the second rotating member, the second end of the second bearing plate is located below the second clamping assembly, and the second clamping assembly cooperates with the second bearing plate to clamp the profile.

[0014] By adopting the above technical solution, the second traction mechanism can achieve stable clamping and precise traction of the profile. The cooperation between the second driving assembly and the second traction slider enables the second traction slider to move back and forth along the profile conveying direction, ensuring the precise positioning and continuity of the profile during the conveying process; the setting of the second rotating member and the second telescopic member realizes the flexible adjustment of the second clamping assembly in space, adapts to profiles of different sizes and shapes, and improves the versatility and operational flexibility of the device; the design of the second extension member being longer than the first extension member avoids interference with the first traction mechanism, allowing the first traction mechanism to pass under the second extension member; the cooperation between the second bearing plate and the second clamping assembly provides reliable support and clamping for the profile, ensuring the processing quality.

[0015] Optionally, upper guiding inclined surfaces are provided on both sides of the upper end surface of the first bearing plate. The two upper guiding inclined surfaces are arranged oppositely, so that an upper receiving groove is formed at the upper end of the first bearing plate. The first clamping assembly includes a support plate and a clamping body. The support plate is connected to the first elongating member, and the clamping body is connected to the lower side of the support plate. A lower guiding inclined surface is provided on the lower end surface of the clamping body. The two lower guiding inclined surfaces are arranged away from each other, so that a lower receiving groove is formed at the lower end of the clamping body. The lower guiding inclined surface is in sliding fit with the upper guiding inclined surface. The maximum length of the lower receiving groove is less than the maximum length of the upper receiving groove, and the minimum length of the lower receiving groove is greater than or equal to the width of the profile.

[0016] By adopting the above technical solution, the upper guiding inclined surfaces provided on the first bearing plate form an upper receiving groove, and the lower guiding inclined surfaces provided at the lower end of the clamping body of the first clamping assembly form a lower receiving groove. The upper and lower guiding inclined surfaces are in sliding fit, making it easy for the clamping body and the first bearing plate to be reliably fitted. At the same time, the width design of the lower receiving groove not only ensures that the profile is firmly clamped but also facilitates the application to profiles of different widths.

[0017] Optionally, the first buffer assembly includes a buffer support member and a buffer inclined member. The buffer support member is arranged on the cutting support member. Along the profile conveying direction, the buffer support member is arranged at the rear end of the cutting assembly. The buffer inclined member is connected to the buffer support member. Along the profile conveying direction, the thickness of the buffer inclined member in the vertical direction increases continuously.

[0018] By adopting the above technical solution, the buffer support member and the buffer inclined member in the first buffer assembly can effectively cooperate with the cutting mechanism. The buffer support member is arranged at the rear end of the cutting assembly to provide stable support for the buffer inclined member. The design that the thickness of the buffer inclined member increases continuously along the profile conveying direction enables the first traction mechanism and the second traction mechanism to gradually receive resistance when approaching the cutting mechanism, so as to achieve smooth deceleration and accurate positioning at a preset distance, ensuring the stability of profile clamping and avoiding profile deviation caused by sudden stop or profile damage or position deviation caused by sudden force.

[0019] Optionally, the second buffer assembly includes a swing plate, a first reset member, a pushing member, a second reset member, a guiding plate, a pushing element, and a lower pressing plate. The swing plate is disposed above the support plate. The first end of the swing plate is rotatably connected to the support plate, and the second end of the swing plate is vertically spaced from the support plate. The swing plate is configured to cooperate with the buffer inclined member so that the buffer inclined member can drive the second end of the swing plate to swing. Two ends of the first reset member are respectively connected to the support plate and the swing plate. The upper end of the pushing member is connected to the second end of the swing plate, and the lower end of the pushing member is connected to the upper end of the second reset member. The pushing member slidably penetrates through the support plate. The lower end of the second reset member is connected to the guiding plate, and the guiding plate is slidably connected to the clamping body. The fixed end of the pushing element is connected to the guiding plate, and the telescopic end of the pushing element is connected to the lower pressing plate. The telescopic end of the pushing element telescopically moves vertically. A sliding groove is provided at the lower end of the clamping body, and the sliding groove communicates with the lower receiving groove. The fixed end of the pushing element is slidably connected to the sliding groove, and the lower pressing plate is slidably connected to the side wall of the sliding groove.

[0020] By adopting the above technical solution, when the first traction mechanism and the second traction mechanism approach the cutting mechanism, the swing plate and the buffer inclined member cooperate with each other, causing the swing plate to rotate, thereby pulling the pushing member to move downward. The downward movement of the pushing member compresses the second reset member and drives the guiding plate to act. The guiding plate is slidably connected to the clamping body, further transmitting the force to the pushing element. The pushing element drives the lower pressing plate to slide along the sliding groove to clamp the profile. The first reset member provides a reset function for the swing plate, enabling the second end of the swing plate to move upward and reset when not under the downward pressure of the buffer inclined member. This structure can effectively improve the clamping stability and accuracy. At the same time, due to the action of the buffer inclined member, the problem of the first traction mechanism and the second traction mechanism quickly hitting the cutting mechanism is avoided, reducing equipment wear and extending the service life.

[0021] Optionally, the first clamping assembly and the second clamping assembly have the same structure, and the first bearing plate and the second bearing plate have the same structure.

[0022] By adopting the above technical solution, the first clamping assembly and the second clamping assembly have the same structure, which can ensure that they have the same performance and accuracy when clamping the profile, thereby improving the clamping stability and consistency. The first bearing plate and the second bearing plate have the same structure, making the force on the two when supporting the profile uniform, avoiding the problem of uneven force caused by structural differences, and further improving the overall reliability of the device. In addition, the design of the same structure is also convenient for production and maintenance, reducing the manufacturing cost and assembly complexity.

[0023] Optionally, the cutting assembly includes a cutting support frame, a cutting driving member, and a cutting blade. The cutting support frame and the cutting driving member are both disposed on the cutting sliding member. The cutting blade is rotatably connected to the cutting support frame, and the output end of the cutting driving member is drivingly connected to the cutting blade.

[0024] By adopting the above technical solution, the cutting assembly can achieve precise cutting of the profile. The cutting support frame provides a stable installation foundation for the cutting blade to ensure the structural stability during the cutting process; the cutting driving member can accurately control the rotation of the cutting blade through driving connection, thereby achieving efficient and accurate cutting of the profile.

[0025] Optionally, the conveying mechanism includes a conveying support and a plurality of conveying components. The conveying components include a connecting member, an elastic member, a pulling member, and a conveying roller. The plurality of conveying components are spaced apart along the profile conveying direction on the conveying support. One end of the connecting member is rotatably connected to the conveying support, and the other end of the connecting member is rotatably connected to the conveying roller. The elastic member and the pulling member are respectively disposed on both sides of the axis of the conveying roller. The first end of the elastic member is connected to the connecting member, and the other end of the elastic member is connected to the conveying support. The first end of the pulling member cooperates with the connecting member, and the other end of the pulling member is rotatably connected to the conveying support.

[0026] By adopting the above technical solution, the conveying mechanism can achieve stable conveying of the profile. Through the cooperation of the elastic member and the pulling member, the connecting member can maintain appropriate tension during the conveying process, ensuring that the friction between the conveying roller and the profile is moderate, thereby avoiding slipping or jamming of the profile during the conveying process; the conveying components are spaced apart on the conveying support, enabling the entire conveying mechanism to evenly support the profile over a long conveying distance, improving the smoothness and reliability of the conveying; the two ends of the connecting member are respectively matched with the conveying support and the conveying roller, and this structural design can adapt to the displacement and angle changes required during the profile conveying process, further enhancing the reliability of the conveying.

[0027] In summary, the present application at least includes the following beneficial technical effects: Through the alternating traction of the first traction mechanism and the second traction mechanism, and through the mutual cooperation of the first buffer assembly and the second buffer assembly, providing resistance when the first traction mechanism and the second traction mechanism approach the cutting mechanism to ensure that the profile is clamped, thereby enhancing the stability during the cutting process. At the same time, it can effectively relieve the accidental displacement or deformation caused by the sudden stop of the profile near the cutting point, significantly improving the cutting accuracy and product quality; the design of the double traction mechanism realizes continuous operation, combined with the precise control of the cutting mechanism, greatly improving the efficiency and automation level of profile processing.

Without contrary explanation, the orientation terms such as "inside, outside" used in this application refer to the contour of the corresponding component itself.

[0036] As Figure 1 shown, an embodiment of this application discloses a double traction circulation auxiliary device (hereinafter simply referred to as "device"). The device includes a conveying mechanism 1, a cutting mechanism 2, a first traction mechanism 3, a second traction mechanism 4, and a buffer mechanism 5, and can achieve efficient conveying, precise cutting, and stable traction of profiles.

[0037] As Figure 1 shown, the conveying mechanism 1 is used to convey profiles, the cutting mechanism 2 is arranged on one side of the conveying mechanism 1, and the cutting mechanism 2 is used to cut profiles. Both the first traction mechanism 3 and the second traction mechanism 4 are arranged on the other side of the conveying mechanism 1 and reciprocate, and both the first traction mechanism 3 and the second traction mechanism 4 are used to clamp and traction profiles. The first traction mechanism 3 and the second traction mechanism 4 alternately traction, and the first traction mechanism 3 passes below the second traction mechanism 4, improving the working efficiency.

[0038] As Figure 2 and Figure 3 shown, the buffer mechanism 5 includes a first buffer component 51 and a second buffer component 52. The first buffer component 51 is arranged on the cutting mechanism 2, and both the first traction mechanism 3 and the second traction mechanism 4 are provided with the second buffer component 52. When the first traction mechanism 3 and the second traction mechanism 4 approach the cutting mechanism 2, the first buffer component 51 can cooperate with one second buffer component 52, so that the first traction mechanism 3 and the second traction mechanism 4 are subjected to resistance at a preset distance from the cutting mechanism 2 and clamp the profiles, avoiding the displacement of the profiles caused by sudden stops, and effectively improving the cutting accuracy and safety.

[0039] As Figure 1 and Figure 4As shown, optionally, the conveying mechanism 1 includes a conveying bracket 11 and a plurality of conveying components 12, which can realize the stable conveying of profiles. The conveying component 12 includes a connecting piece 121, an elastic piece 122, a pulling piece 123 and a conveying roller 124. The plurality of conveying components 12 are spaced along the profile conveying direction on the conveying bracket 11, so that the entire conveying mechanism 1 can uniformly support the profile over a long conveying distance, improving the smoothness and reliability of conveying. One end of the connecting piece 121 is rotatably connected to the conveying bracket 11, and the other end of the connecting piece 121 is rotatably connected to the conveying roller 124, thereby supporting the conveying roller 124.

The elastic piece 122 can be a spring; the pulling piece 123 can be a structure capable of realizing telescoping such as a cylinder, a hydraulic cylinder or an electric telescopic rod.

The first drive assembly 31 is disposed on one side of the conveying mechanism 1. The first traction slider 32 is drivingly connected to the first drive assembly 31, causing the first traction slider 32 to reciprocate along the profile conveying direction, providing power for the conveyance of the profile. The fixed end of the first rotating member 33 is disposed on the first traction slider 32. The fixed end of the first telescopic member 34 is disposed on the rotating end of the first rotating member 33. The telescopic end of the first telescopic member 34 extends vertically and is connected to the first end of the first elongating member 35 that extends horizontally. The second end of the first elongating member 35 is connected to the first clamping assembly 37. The cooperation between the first rotating member 33 and the first telescopic member 34 enables the first clamping assembly 37 to flexibly adjust its position, ensuring the accuracy of the clamping operation. The first end of the first bearing plate 36 is connected to the rotating end of the first rotating member 33. The second end of the first bearing plate 36 is located below the first clamping assembly 37. The first clamping assembly 37 cooperates with the first bearing plate 36 to clamp the profile. The first bearing plate 36 and the first clamping assembly 37 cooperate with each other to form a stable clamping structure, effectively preventing the profile from shifting or sliding during conveyance. The first rotating member 33 can drive the first bearing plate 36 and the first clamping assembly 37 to rotate, thereby avoiding the second traction mechanism 4 during the return stroke.

[0043] As Figure 1 and Figure 5As shown, optionally, the second traction mechanism 4 includes a second drive assembly 41, a second traction slider 42, a second rotating member 43, a second telescopic member 44, a second elongating member 45, a second bearing plate 46, and a second clamping assembly 47.

The second traction slider 42 is drivingly connected to the second drive assembly 41 to reciprocate the second traction slider 42 in the profile conveying direction, ensuring accurate positioning and continuity of the profile during conveying. The fixed end of the second rotating member 43 is disposed on the second traction slider 42. The fixed end of the second telescopic member 44 is disposed on the rotating end of the second rotating member 43. The telescopic end of the second telescopic member 44 extends vertically and is connected to the first end of the second elongating member 45 that extends horizontally. The second end of the second elongating member 45 is connected to the second clamping assembly 47. The length of the second elongating member 45 is greater than the length of the first elongating member 35. The first end of the second bearing plate 46 is connected to the rotating end of the second rotating member 43. The second end of the second bearing plate 46 is located below the second clamping assembly 47. The second clamping assembly 47 cooperates with the second bearing plate 46 to clamp the profile. The rotation of the rotating end of the second rotating member 43 enables the second clamping assembly 47 to avoid the first traction mechanism 3 during the return stroke. Both the first drive assembly 31 and the second drive assembly 41 can be motors; both the first rotating member 33 and the second rotating member 43 can be oscillating cylinders; both the first telescopic member 34 and the second telescopic member 44 can be structures capable of achieving telescoping, such as cylinders, hydraulic cylinders, or electric telescopic rods.

[0044] As Figure 1 , Figure 2 and Figure 5As shown, the arrangement of the second rotating member 43 and the second telescopic member 44 enables flexible adjustment of the second clamping assembly 47 in space, enhancing the versatility and operational flexibility of the device. The design that the length of the second extension member 45 is greater than that of the first extension member 35 avoids interference with the first traction mechanism 3, allowing the first traction mechanism 3 to pass under the second extension member 45. The cooperation between the second bearing plate 46 and the second clamping assembly 47 provides reliable support and clamping for the profile, ensuring the processing quality. The distance between the two conveying rollers 124 is sufficient to enable the first traction mechanism 3 and the second traction mechanism 4 to rotate and swing without interference.

The first clamping assembly 37 and the second clamping assembly 47 can be made of lightweight materials to reduce the weight. Along the conveying direction of the profile, the lengths of the first clamping assembly 37 and the second clamping assembly 47 can be set as required.

[0045] As Figure 1 , Figure 2 and Figure 5 shown, optionally, the first clamping assembly 37 and the second clamping assembly 47 have the same structure, which can ensure that they have the same performance and accuracy when clamping the profile, thereby improving the clamping stability and consistency.

[0046] As Figure 1 and Figure 2 shown, optionally, upper guiding inclined surfaces 361 are provided on both sides of the upper end surface of the first bearing plate 36. The two upper guiding inclined surfaces 361 are arranged oppositely, forming an upper receiving groove with an upward opening at the upper end of the first bearing plate 36. The first clamping assembly 37 includes a support plate 371 and a clamping body 372. The support plate 371 is connected to the first extension member 35, and the clamping body 372 is connected to the lower side of the support plate 371. Lower guiding inclined surfaces 3721 are provided on the lower end surface of the clamping body 372. The two lower guiding inclined surfaces 3721 are arranged away from each other, forming a lower receiving groove with a downward opening at the lower end of the clamping body 372. The lower guiding inclined surfaces 3721 are in sliding cooperation with the upper guiding inclined surfaces 361. The maximum length of the lower receiving groove is less than the maximum length of the upper receiving groove, and the minimum length of the lower receiving groove is greater than or equal to the width of the profile.

[0047] The upper guiding inclined surface 361 provided on the first bearing plate 36 forms an upper receiving groove, and the lower guiding inclined surface 3721 provided at the lower end of the clamping body 372 of the first clamping assembly 37 forms a lower receiving groove. The upper and lower guiding inclined surfaces 3721 are in sliding fit, enabling the clamping body 372 and the first bearing plate 36 to be easily and reliably fitted, thereby stably clamping the profile. At the same time, the width design of the lower receiving groove not only ensures that the profile is firmly clamped but also facilitates the application to profiles of different widths. The height of the receiving groove formed by the upper receiving groove and the lower receiving groove is set as required to achieve the clamping effect on the profile. The setting of the receiving groove can reduce the horizontal movement of the profile and improve the traction stability and reliability.

[0048] As Figure 1 and Figure 3 shown, optionally, the first buffer assembly 51 includes a buffer support member 511 and a buffer inclined member 512, and the buffer support member 511 and the buffer inclined member 512 can effectively cooperate with the cutting mechanism 2. The buffer support member 511 is provided on the cutting support member 21. Along the profile conveying direction, the buffer support member 511 is provided at the rear end of the cutting assembly 26, and the buffer inclined member 512 is connected to the buffer support member 511. Along the profile conveying direction, the thickness of the buffer inclined member 512 in the vertical direction continuously increases.

[0049] The buffer support member 511 provides stable support for the buffer inclined member 512, and the design that the thickness of the buffer inclined member 512 continuously increases along the profile conveying direction enables the first traction mechanism 3 and the second traction mechanism 4 to gradually receive resistance when approaching the cutting mechanism 2, thereby achieving smooth deceleration and accurate positioning at a preset distance, ensuring the stability of profile clamping, and avoiding profile deviation caused by sudden stop or profile damage or position deviation caused by sudden force.

[0050] As Figure 1 and Figure 2As shown, optionally, the second buffer assembly 52 includes a swing plate 521, a first reset member 522, a pushing member 523, a second reset member 524, a guiding plate 525, a pushing member 526, and a lower pressing plate 527. The swing plate 521 is disposed above the support plate 371. The first end of the swing plate 521 is rotatably connected to the support plate 371. The second end of the swing plate 521 is vertically spaced from the support plate 371. The swing plate 521 is used to cooperate with the buffer inclined member 512 so that the buffer inclined member 512 can drive the second end of the swing plate 521 to swing. Both ends of the first reset member 522 are respectively connected to the support plate 371 and the swing plate 521. The upper end of the pushing member 523 is connected to the second end of the swing plate 521. The lower end of the pushing member 523 is connected to the upper end of the second reset member 524. The pushing member 523 slidably penetrates through the support plate 371. The lower end of the second reset member 524 is connected to the guiding plate 525. The guiding plate 525 is slidably connected to the clamping body 372. The fixed end of the pushing member 526 is connected to the guiding plate 525. The telescopic end of the pushing member 526 is connected to the lower pressing plate 527. The telescopic end of the pushing member 526 telescopically moves vertically. A sliding groove is provided at the lower end of the clamping body 372. The sliding groove communicates with the lower accommodation groove. The fixed end of the pushing member 526 is slidably connected to the sliding groove. The lower pressing plate 527 is slidably connected to the side wall of the sliding groove. Both the first reset member 522 and the second reset member 524 can be springs; the pushing member 523 is a rod-shaped member; the pushing member 526 is a structure capable of telescoping such as a cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0051] As Figure 1 , Figure 2 and Figure 3 shown, when the first traction mechanism 3 and the second traction mechanism 4 approach the cutting mechanism 2, the swing plate 521 and the buffer inclined member 512 cooperate with each other, causing the second end of the swing plate 521 to rotate around the first end, thereby pushing the pushing member 523 to move downward. The downward movement of the pushing member 523 compresses the second reset member 524 and as the downward movement amount increases, it can drive the guiding plate 525 to move downward. The guiding plate 525 is slidably connected to the clamping body 372, further transmitting the force to the pushing member 526. The pushing member 526 drives the lower pressing plate 527 to slide along the sliding groove to clamp the profile. The first reset member 522 provides a reset function for the swing plate 521, enabling the second end of the swing plate 521 to move upward and reset when not under the downward pressing action of the buffer inclined member 512. This structure can effectively improve the clamping stability and accuracy. At the same time, due to the action of the buffer inclined member 512, the problem of the first traction mechanism 3 and the second traction mechanism 4 quickly hitting the cutting mechanism 2 is avoided, reducing equipment wear and extending the service life.

[0052] In use, according to needs, while the pusher 526 moves integrally to achieve the pressing-down effect, the telescopic end of the pusher 526 can be used to expand and contract to achieve further pressing-down, so as to further improve the pressing effect on the profile. The device can also be provided with a vertical telescopic member 38. The first bearing plate 36 is connected to the rotating end of the first rotating member 33 through the vertical telescopic member 38, and the second bearing plate 46 is connected to the rotating end of the second rotating member 43 through the vertical telescopic member 38. The vertical telescopic member 38 is used to drive the first bearing plate 36 or the second bearing plate 46 to move vertically, so that the vertical heights of the first bearing plate 36 and the second bearing plate 46 can be adjusted, so as to smoothly move below the profile. The vertical telescopic member 38 can be a structure such as a cylinder, a hydraulic cylinder or an electric telescopic rod that can achieve expansion and contraction.

[0053] It can be understood that the device also includes necessary structures for functions such as connection, support, drive, positioning, limit and control, so that the device can operate normally; parameters such as the shape, size, material and setting quantity of each part of the device can be determined according to needs, as long as the corresponding functions can be achieved.

[0054] The implementation principle of a double-traction circulation auxiliary device in an embodiment of the present application is as follows: The conveying mechanism 1 conveys profiles, and the first traction mechanism 3 and the second traction mechanism 4 work alternately. During the process of clamping and traction the profiles, the first traction mechanism 3 can pass under the second traction mechanism 4, avoiding interference between the two and improving work efficiency. When the first traction mechanism 3 or the second traction mechanism 4 approaches the cutting mechanism 2, the first buffer assembly 51 and the second buffer assembly 52 in the buffer mechanism 5 cooperate with each other. As the distance decreases, the first traction mechanism 3 or the second traction mechanism 4 is gradually subjected to resistance, thereby prompting them to clamp the profiles, ensuring the stability during the cutting process of the cutting mechanism 2 on the profiles, and thus achieving the purpose of precise cutting and efficient traction.

[0055] The above are all preferred embodiments of the present application. Without restricting the protection scope of the present application based on this, therefore: All equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
