A steel structure profile cutting equipment

Abstract

This invention provides a steel structure profile cutting device, including a transmission component, a cutting component, a blanking component, a diversion drive component, and a positioning component. The transmission component conveys the profile via a carrier roller A, while the blanking component uses a liftable carrier roller B for automatic blanking. The diversion drive component independently drives the transmission and blanking actions via a ratchet mechanism, avoiding interference. The positioning component includes a width-fixing mechanism, a thickness-adapting mechanism, and a guide clamping mechanism, which can adaptively adjust the clamping position to ensure stable guidance of the profile during transmission and secure fixation during cutting. The cutting component uses a hydraulically driven disc saw for precise cutting. This equipment features high-precision positioning, automated adjustment, and efficient continuous operation, making it suitable for fixed-length cutting of heavy profiles such as large steel ingots and steel columns, effectively improving processing efficiency and cutting quality.

Description

Technical Field

[0001] This invention relates to the field of profile cutting technology, specifically a steel structure profile cutting device. Background Technology

[0002] In the field of steel structure fabrication, fixed-length cutting of heavy steel structure profiles is a common but technically challenging process. Traditional cutting equipment typically employs fixed-position saws or flame cutting devices, but these devices often suffer from the following technical drawbacks during the cutting process:

[0003] 1. Insufficient positioning accuracy: Traditional equipment has relatively simple clamping and guiding functions for profiles. Especially when cutting heavy profiles, the profiles are prone to shift due to their own weight or cutting vibration, resulting in uneven cut surfaces or increased length errors, which affect the accuracy of subsequent processing and assembly.

[0004] 2. Low level of automation: Existing equipment typically requires manual intervention for positioning, feeding, and unloading, which is not only inefficient but also poses safety hazards. For large profiles, manual handling and adjustment are difficult and labor-intensive.

[0005] 3. Poor adaptability: Profiles with different cross-sectional dimensions (such as width and thickness) require frequent adjustments to equipment parameters or replacement of fixtures. The adjustment mechanism of traditional equipment is complex and time-consuming, making it difficult to quickly adapt to the cutting needs of multiple specifications of profiles.

[0006] 4. Unreasonable power distribution: Some equipment uses a single drive source to control both the transmission and unloading mechanisms, which causes interference between the cutting and unloading processes. For example, uncut profiles may be accidentally moved during unloading, affecting the continuity of the overall operation.

[0007] Therefore, there is an urgent need for a new type of steel structure profile cutting equipment that can achieve high-precision positioning, adaptive clamping, and independent drive transmission and unloading functions, while improving the level of automation and compatibility with multiple specifications of profiles. Summary of the Invention

[0035] Based on the above technical solutions, in order to ensure that the guide clamping mechanism can be stably assembled on the main lifting seat and the auxiliary lifting seat, and to realize the adjustment of the guide transmission and clamping cutting functions, the following technical solutions are provided.

[0036] The guiding and clamping mechanism includes multiple sets of corresponding and matching fixed brackets, sliding brackets, guide wheels, clamping plates, and attitude adjustment mechanisms. The fixed brackets are fixedly installed on the main lifting seat or the auxiliary lifting seat. The guide wheels are rotatably installed on the fixed brackets. The sliding brackets are slidably installed on the main lifting seat or the auxiliary lifting seat. The clamping plates are fixedly installed on the sliding brackets.

[0041] The beneficial effects of this invention are:

[0042] 1. High-precision positioning and stable cutting: Through the coordinated action of the width-fixing mechanism, thickness-adapting mechanism, and guide clamping mechanism, the clamping position can be automatically adjusted according to the width and thickness of the profile, ensuring that the profile remains stable during transmission and cutting, avoiding deviation or vibration, and improving cutting accuracy; the guide clamping mechanism can switch between the guide transmission mode and the clamping cutting mode, ensuring smooth feeding and providing firm fixation during cutting, reducing cutting errors.

[0043] 2. High degree of automation, reducing manual intervention: The power distribution drive component uses two sets of reverse ratchet mechanisms to split the power, allowing the transmission and unloading components to operate independently and avoiding mutual interference. During unloading, uncut profiles remain stationary, while only cut profiles are automatically lifted and conveyed, improving operational continuity. The thickness adaptation mechanism adjusts the motor, spline shaft, and lead screw structure to achieve precise lifting of the main and auxiliary lifting seats, allowing the clamping mechanism to adapt to profiles of different thicknesses and reducing manual adjustment time.

[0044] 3. Highly adaptable and compatible with various profile specifications. The width-fixing mechanism adopts a symmetrically arranged traveling beam seat and a two-way adjusting screw, which can quickly adjust the spacing of the clamping mechanisms on both sides to adapt to profiles of different widths. The thickness-adapting mechanism, through multi-level lifting adjustment, enables the guide clamping mechanism to be positioned for different heights of the profile sidewall, ensuring clamping stability. It is suitable for various heavy profiles such as steel ingots and steel columns.

[0045] 4. Optimized structure ensures stable and reliable operation. The transmission, feeding, cutting, and positioning components all adopt independent assembly structures, facilitating maintenance and replacement and reducing equipment failure rates. The positioning component is positioned at the gap between the carrying rollers to avoid motion interference with the transmission and feeding mechanisms, ensuring coordinated equipment operation. The attitude adjustment mechanism uses worm gear transmission to ensure that it will not loosen due to external forces under clamping conditions, improving stability during cutting.

[0046] 5. High-efficiency material feeding improves production efficiency. The bearing roller B of the feeding component can be raised and lowered under the drive of a winch. After cutting, it automatically lifts the profile and transports it downstream without manual handling, thus improving production efficiency. Since the transmission and feeding are independently controlled, continuous production is achieved, which is suitable for mass processing operations. Attached Figure Description

Detailed Implementation

[0068] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0069] Please see Figure 1 , Figure 2 , Figure 7 A steel structure profile cutting device, comprising:

[0070] Transmission component 1 is arranged horizontally and is used to support and transmit steel structural profiles;

[0071] Cutting component 2 is assembled onto the transmission component 1 and used to cut steel structure profiles;

[0072] The feeding component 3 is matched with the transmission component 1 and arranged on the downstream side of the cutting component 2. The feeding component 3 is used to automatically feed the steel structure profiles to be cut.

[0073] Diverting drive component 4 is connected to the transmission component 1 and the unloading component 3 by a power connection. Diverting drive component 4 is used to drive the transmission component 1 and the unloading component 3 to run.

[0074] The positioning component 5 includes a width-fixing mechanism 51, a thickness-adapting mechanism 52, and a guide clamping mechanism 53. The width-fixing mechanism 51 is assembled on both sides of the transmission component 1 and runs along the transmission direction perpendicular to the steel structure profile. The thickness-adapting mechanism 52 is assembled on the width-fixing mechanism 51 and is used for vertical posture adjustment. The guide clamping mechanism 53 is assembled on the movable part of the thickness-adapting mechanism 52 and is used for clamping, cutting, or guiding the transmission of the steel structure profile.

[0075] The cutting equipment provided in this application is mainly used for cutting steel structural profiles with large weight and volume, such as cutting large steel ingots and steel columns to a fixed length. During cutting, the transmission component 1 stably transmits the profile to be cut and stably transmits it to the cutting component 2 and the unloading component 3.

[0076] During transmission, the positioning component 5 provides stable lateral support and guidance for the profile. Specifically, by adjusting the thickness adaptation mechanism 52, the guide clamping mechanism 53 of different heights is made to be horizontally aligned with the different thickness positions on the side of the profile. By adjusting the width fixing mechanism 51, the thickness adaptation mechanism 52 and the guide clamping mechanism 53 on both sides are driven to move in opposite directions, so that the guide clamping mechanism 53 can effectively fit with the two sides of the profile. Then, the guide clamping mechanism 53 is controlled to be in the orientation of guiding transmission, so as to stably transmit and feed the profile transmitted on the transmission component 1.

[0077] When a specific length of the profile moves to the position of the cutting component 2, the control guide clamping mechanism 53 is in a clamping and cutting posture to avoid invalid displacement during the profile cutting process, so as to ensure the accuracy of the cutting length. Finally, the effective cutting of the profile is completed through the operation of the cutting component 2.

[0078] After the profile is cut, the fixed-length profile downstream of the cutting component 2 can be lifted upward by the running feeding component 3. When the feeding component 3 is running independently, it can continue to transmit the cut profile downstream. At this time, the transmission component 1 is in standby mode and will not drive the uncut profile it carries to continue to feed forward.

[0079] The diversion drive component 4 can provide independent driving force to the transmission component 1 and the unloading component 3, so as to drive the transmission component 1 or the unloading component 3 to operate independently. While simplifying the drive components, it can avoid interference of the operation of the transmission component 1 and the unloading component 3 with the profile shaping motion, and improve the rationality of equipment operation. Example

[0080] Please see Figure 1 , Figure 2 To ensure that the transmission component 1 can effectively carry the cut steel structure profile and achieve stable transmission of the profile, the following technical solution is provided.

[0081] The transmission component 1 includes multiple sets of bearing rollers A11 arranged side by side in the horizontal direction. A sprocket A111 is coaxially fixed to the same end of each set of bearing rollers A11. The sprockets A111 on each set of bearing rollers A11 are connected to each other by a chain.

[0082] The transmission assembly 1 also includes a mounting frame 12, on which each set of bearing rollers A11 is rotatably mounted.

[0083] The mounting frame 12 ensures that each bearing roller A11 is stably assembled and operated on it. Each set of bearing rollers A11 arranged side by side can effectively support the steel structure profile. The ends of the bearing rollers A11 at both ends of the mounting frame 12 are provided with a set of sprockets A111, while the ends of each bearing roller A11 on the inner side are provided with two sets of sprockets A111, so that adjacent sets of bearing rollers A11 can be connected by independent chains, thereby ensuring that each bearing roller A11 always maintains the same speed and direction of operation, so as to achieve stable transmission and feeding of the profiles carried on it.

[0084] To ensure that the feeding component 3 can be stably assembled on the transmission component 1 and achieve a matching combination with the transmission component 1, and to ensure that the feeding component 3 can lift the profile cut by the downstream side of the cutting component 2 upward and carry it out for feeding and transmission, the following technical solution is provided.

[0085] The unloading assembly 3 includes a lifting bracket 31 and a bearing roller B32 rotatably mounted on the lifting bracket 31 and arranged side by side in the horizontal direction. The bearing roller B32 is arranged in the gap between adjacent bearing rollers A11. A sprocket B321 is coaxially fixed to the same end of each set of bearing rollers B32. The sprockets B321 on different bearing rollers are connected by a chain for power connection.

[0086] The mounting frame 12 is also fixedly connected to a vertically arranged guide column 121. The top of the guide column 121 is fixedly connected to a mounting platform 122. The lifting bracket 31 is slidably installed on the guide column 121 and moves up and down in the vertical direction.

[0087] The unloading assembly 3 also includes a winch 33, which is mounted on the installation platform 122. The steel wire rope extending from the winch 33 is fixedly connected to the lifting bracket 31.

[0088] The guide column 121 and mounting platform 122 on the mounting frame 12 can ensure that the feeding component 3 is stably assembled on it and can be matched with the carrying roller A11 in the transmission component 1.

[0089] Each of the bearing rollers B32 at both ends of the lifting bracket 31 is equipped with a set of sprockets B321, while each of the other bearing rollers B32 on the inner side is equipped with two sets of sprockets B321, so that adjacent sets of bearing rollers B32 can be connected by chains, thereby ensuring that each set of bearing rollers B32 always maintains the same speed and direction.

[0090] When the winch 33 is running, it can drive the lifting bracket 31 to rise and fall stably along the guide column 121, thereby adjusting the height of the bearing roller B32. When the unloading assembly 3 is in the initial state, the lifting bracket 31 is at the bottom of its stroke so that the bearing roller B32 is not higher than the bearing roller A11, which can ensure that the profile is stably supported and transported on the bearing roller A11. After the cutting assembly 2 completes the cutting of the profile, the unloading assembly 3 is controlled to run so that the winch 33 drives the lifting bracket 31 and the bearing roller B32 to move upward. At this time, the profile that is downstream of the cutting assembly 2 and cut into a fixed length can be lifted upward by the bearing roller B32 and removed from the support of the bearing roller A11. It is then stably transported and unloaded downstream by the running bearing rollers B32, and finally the fixed-length cut profile is transferred or stacked by the hoisting or stacking equipment assembled at the downstream end of the equipment.

[0091] Since the feeding component 3 and the transmission component 1 are designed independently, when the feeding component 3 performs the feeding operation, the uncut profile located upstream of the cutting component 2 and carried by the bearing roller A11 is in a stationary state, which can avoid interference to the uncut profile when the feeding component 3 performs the feeding operation. Example

[0092] Please see Figures 2-5 To ensure that the power distribution drive component 4 can achieve stable power transmission with the transmission component 1 and the unloading component 3, and to achieve power distribution drive for the transmission component 1 and the unloading component 3, and to ensure that the transmission component 1 and the unloading component 3 always maintain a single independent operating posture, the following technical solution is provided.

[0093] The split drive assembly 4 includes a drive motor 41, a first spline shaft 42, and two sets of ratchet mechanisms 43 arranged in opposite directions. The drive motor 41 is powered to the input ends of the two sets of ratchet mechanisms 43. The first spline shaft 42 is arranged vertically and powered to one of the bearing rollers B32. The output ends of the two sets of ratchet mechanisms 43 are powered to the first spline shaft 42 and one of the bearing rollers A11, respectively.

[0094] Both sets of ratchet mechanisms 43 include an inner ratchet 431 and a pawl 432 that meshes with the inner ratchet 431. The inner ratchet 431s in both sets of ratchet mechanisms 43 are arranged coaxially and in opposite directions, and are rotatably mounted on the mounting frame 12. The drive motor 41 is a geared motor and is fixedly mounted on the mounting frame 12. A mounting shaft 411, which passes through the axis of the inner ratchet 431, is coaxially fixed to the output shaft of the drive motor 41. The pawls 432 of both sets of ratchet mechanisms 43 are rotatably mounted to the periphery of the mounting shaft 411. The ratchet mechanism 43 also includes a spring 433 assembled on the mounting shaft 411 and abutting against the pawl 432. The spring 433 provides an outward extending force for the pawl 432, thereby ensuring stable meshing between the pawl 432 and the inner ratchet 431.

[0095] Two sets of ratchet mechanisms 43 arranged in opposite directions can transmit the forward and reverse rotation of the drive motor 41, respectively. The pawl 432 serves as the input end of the ratchet mechanism 43, while the inner ratchet 431 serves as the output end. When the drive motor 41 rotates forward, it drives the mounting shaft 411 and the pawl 432 mounted on it to rotate synchronously. At this time, only the pawl 432 in one set of ratchet mechanisms 43 can mesh with the inner ratchet 431 and drive it to rotate, while the inner ratchet 431 and pawl 432 in the other set of ratchet mechanisms 43 remain in a slipping state and cannot transmit power. The same principle applies when the drive motor 41 rotates in the reverse direction, thus achieving the split transmission of power to the drive motor 41.

[0096] Because the unloading assembly 3 has a lifting motion design, and the No. 1 spline shaft 42 can ensure that the unloading assembly 3 maintains stable power transmission during lifting motion.

[0097] To ensure that the output ends of the two sets of ratchet mechanisms 43 can stably transmit power to the feeding assembly 3 and the transmission assembly 1, the following technical solution is provided.

[0098] The output ends of the two sets of ratchet mechanisms 43 are respectively fixed to drive bevel gears A434 and B435. Drive bevel gears A434 and B435 are respectively meshed with transmission bevel gears A441 and B442. Transmission bevel gear A441 is coaxially fixed to a connecting shaft 443, and transmission bevel gear B442 is coaxially fixed to a first spline shaft 42.

[0099] One set of bearing rollers A11 and B32 are respectively fixed with transmission bevel gears a112 and b322. A drive bevel gear a444 is fixed to the connecting shaft 443 and meshes with the transmission bevel gear a112. The transmission bevel gear b322 is meshed with the drive bevel gear b445. The drive bevel gear b445 is slidably inserted into the first spline shaft 42.

[0100] The inner ratchet 431 of the two sets of ratchet mechanisms 43 is respectively fixed with drive bevel gear A434 and drive bevel gear B435. Transmission bevel gear A441, transmission bevel gear B442, spline shaft, and connecting shaft 443 are all rotatably mounted on the mounting frame 12, which can effectively receive the power of the corresponding ratchet mechanism 43 and drive the spline shaft and connecting shaft 443 to operate stably.

[0101] The rotating connecting shaft 443 can drive the bearing roller A11 to operate stably through the combination of driving bevel gear a444 and transmission bevel gear a112. The driving bevel gear b445 is rotatably mounted on the lifting bracket 31 and rises and falls synchronously with the unloading assembly 3. During this process, the driving bevel gear b445 can always receive the power of the first spline shaft 42, and thus the combination of driving bevel gear b445 and transmission bevel gear b322 drives the bearing roller B32 at any height position to always maintain stable operation.

[0102] The direction of power transmission can be changed by adjusting the position and orientation of each bevel gear, thereby enabling both the transmission component 1 and the feeding component 3 to stably transmit the profile to the downstream side during operation. No further explanation will be given here. Example

[0103] Please see Figure 6 To ensure that the cutting component 2 can be stably assembled on the transmission component 1 and to achieve effective cutting of steel structure profiles, the following technical solution is provided.

[0104] The cutting assembly 2 includes an assembly bracket 21, a horizontal slide block 22, a vertical support 23, a hydraulic telescopic cylinder A25, a hydraulic telescopic cylinder B26, and a circular saw 27. The assembly bracket 21 is fixedly installed on the mounting frame 12 and arranged between two adjacent sets of bearing rollers A11. The horizontal slide block 22 is slidably installed on the assembly bracket 21 and runs in a direction perpendicular to the transmission direction of the transmission assembly 1. The hydraulic telescopic cylinder A25 is fixedly installed on the assembly bracket 21 and is poweredly connected to the horizontal slide block 22. The vertical support 23 is slidably installed on the horizontal slide block 22 and moves up and down in the vertical direction. The hydraulic telescopic cylinder B26 is fixedly installed on the horizontal slide block 22 and is poweredly connected to the vertical support 23. The circular saw 27 is fixedly installed at the bottom of the vertical support 23.

[0105] The mounting bracket 21 ensures the stable installation of the other components of the cutting equipment. The hydraulic telescopic cylinder A25 drives the horizontal slide 22 and the vertical bracket 23 and the disc saw 27 mounted on it to move perpendicular to the profile transmission direction, so as to realize the stable operation of the disc saw 27 along the cutting path. The hydraulic telescopic cylinder B26 drives the vertical bracket 23 and the disc saw 27 to move in the vertical direction, so that the disc saw 27 can effectively contact or separate from the profile, thereby effectively cutting the profile. Example

[0106] Please see Figure 1 , Figure 2 , Figures 7-11 To ensure that the width-fixing mechanism 51 in the positioning component 5 can operate stably along the width direction of the transmission component 1 and the profile, and thereby control the thickness-adapting mechanism 52 and the guide clamping mechanism 53 to effectively act on the side of the profile, the following technical solution is provided.

[0107] The width-fixing mechanism 51 includes two sets of traveling beam seats 511 that maintain symmetrical movement, as well as an adjusting motor A512 and an adjusting screw A513. The traveling beam seats 511 are assembled onto the mounting frame 12 and run along the width direction of the transmission assembly 1. The adjusting motor A512 and the adjusting screw A513 are connected by power, and the adjusting screw A513 is screwed to the two sets of traveling beam seats 511.

[0108] Multiple sets of travel guide rails 123 arranged along their width direction are fixedly installed on the mounting frame 12. Multiple sets of travel wheels 5111 that are matched with the travel guide rails 123 are rotatably installed at the bottom of the two sets of travel beam seats 511, so that the travel beam seats 511 can travel stably on the mounting frame 12.

[0109] Multiple sets of adjusting screws A513 can be evenly arranged. A transmission sprocket 5131 is fixedly connected to the same end of each adjusting screw A513. Each set of transmission sprockets 5131 is connected to the power through a chain to ensure that each adjusting screw A513 always operates synchronously. The adjusting motor A512 is fixedly installed on the mounting frame 12, and its output shaft is directly connected to one of the sets of adjusting screws A513.

[0110] Each adjusting screw A513 is provided with two sections of threaded grooves with opposite helical directions. The two sections of threaded grooves are respectively screwed into the two sets of traveling beam seats 511, thereby enabling the two sets of traveling beam seats 511 to always maintain symmetrical movement.

[0111] The traveling beam seat 511 is arranged at the bottom and gap of the bearing roller A11 and the bearing roller B32, which can effectively prevent the spatial movement interference between the running positioning component 5 and the transmission component 1 and the unloading component 3.

[0112] To ensure that the thickness adaptation mechanism 52 can be stably assembled on the width-fixing mechanism 51, and to enable the guide clamping mechanism 53 to adaptively adjust its height and position according to the profile thickness, so as to ensure that the guide clamping mechanism 53 can effectively act on the side of the profile, the following technical solution is provided.

[0113] The thickness adaptation mechanism 52 includes multiple sets of corresponding matching main lifting seats 521, auxiliary lifting seats 522, adjusting screws B523 and C524, and a second spline shaft A525. Multiple sets of main lifting seats 521 that move vertically are slidably installed on the traveling beam seat 511. Auxiliary lifting seats 522 that move vertically are slidably installed on the main lifting seats 521. Adjusting screws B523 are rotatably installed on the traveling beam seat 511 and are screwed into the main lifting seats 521. Adjusting screws C524 are rotatably installed on the main lifting seats 521 and are screwed into the auxiliary lifting seats 522. The second spline shaft A525 is rotatably installed on the traveling crossbeam and is slidably inserted into the adjusting screws C524. Guide clamping mechanisms 53 are installed on both the main lifting seats 521 and the auxiliary lifting seats 522.

[0114] Each main lifting seat 521, auxiliary lifting seat 522, and the matching guide clamping mechanism 53 are arranged at the gap between the bearing roller A11 and the bearing roller B32 to avoid spatial movement interference with the transmission component 1 and the unloading component 3, while ensuring that the thickness matching mechanism 52 and the guide clamping mechanism 53 are arranged as evenly as possible along the length of the transmission component 1.

[0115] When the adjusting screw B523 is running, it can drive the main lifting seat 521 and the guide clamping mechanism 53 thereon to rise and fall stably in the vertical direction. When controlling the second spline shaft A525 to run, it can stably transmit power to the adjusting screw C524, so that the adjusting screw C524 can always stably receive the power of the second spline shaft A525 during the synchronous rising and falling motion with the main lifting seat 521, thereby driving the auxiliary lifting seat 522 and the guide clamping mechanism 53 thereon to rise and fall on the main lifting seat 521.

[0116] The thickness adaptation mechanism 52 also includes an adjusting motor B5261, an adjusting motor C5271, a second spline shaft B5262, a second spline shaft C5272, a drive shaft A5263, and a drive shaft B5273. The second spline shafts B5262 and C5272 are arranged perpendicular to the traveling beam seat 511 and are respectively connected to the adjusting motors B5261 and C5271. The traveling beam seat 511 is rotatably mounted with components respectively connected to the second spline shafts B5262 and C5272. The drive bevel gears C5112 and D5113, which are slidably connected, and the drive shafts A5263 and B5273 are rotatably mounted in the travel beam seat 511 and arranged along the length of the travel beam seat 511. The drive shafts A5263 and B5273 are respectively fixedly connected to the drive bevel gears C5264 and D5274, which are engaged with the drive bevel gears C5112 and D5113, respectively.

[0117] Adjustment motors B5261 and C5271 are fixedly installed on the mounting frame 12, and their output shafts are coaxially connected with the second spline shafts B5262 and C5272, respectively. The second spline shafts B5262 and C5272 are rotatably installed on the mounting frame 12 and are arranged through the travel beam seat 511.

[0118] During the movement of the traveling beam seat 511, the power of the second spline shaft B5262 and the second spline shaft C5272 can always be transmitted to the drive shaft A5263 and the drive shaft B5273 through the drive bevel gear C5112, drive bevel gear D5113, transmission bevel gear C5264 and transmission bevel gear D5274, and then the drive shaft A5263 and the drive shaft B5273 drive the adjusting screw B523 and the adjusting screw C524 to operate stably.

[0119] Drive bevel gears c5265 and d5275 are fixedly connected to drive shafts A5263 and B5273, respectively. Drive bevel gears c5231 and d5251 are fixedly connected to the bottom ends of adjusting screw B523 and second spline shaft A525, respectively. Drive bevel gears c5231 and d5251 are engaged with drive bevel gears c5265 and d5275, respectively.

[0120] Drive shafts A5263 and B5273 can drive adjusting screw B523 and second spline shaft A525 to operate stably via drive bevel gears c5265, d5275, c5231, and d5251. In turn, second spline shaft A525 can drive adjusting screw C524 to operate stably.

[0121] By adjusting the height of the main lifting seat 521 and the auxiliary lifting seat 522, the guide clamping mechanism 53 mounted on them can effectively act on different height positions of the profile sidewall to provide a guiding effect for the transmission of the profile, thereby avoiding invalid offset during the profile feeding process that affects the cutting accuracy. It can also provide clamping force for the profile to avoid invalid offset during the cutting process that affects the cutting accuracy. Example

[0122] Please see Figures 9-12 To ensure that the guide clamping mechanism 53 can be stably assembled on the main lifting seat 521 and the auxiliary lifting seat 522, and to realize the adjustment of the guide transmission and clamping cutting functions, the following technical solution is provided.

[0123] The guide clamping mechanism 53 includes multiple sets of corresponding matching fixed brackets 531, sliding brackets 532, guide wheels 533, clamping plates 534, and attitude adjustment mechanisms 535. The fixed brackets 531 are fixedly installed on the main lifting seat 521 or the auxiliary lifting seat 522. The guide wheels 533 are rotatably installed on the fixed brackets 531. The sliding brackets 532 are slidably installed on the main lifting seat 521 or the auxiliary lifting seat 522. The clamping plates 534 are fixedly installed on the sliding brackets 532. The attitude adjustment mechanisms 535 are assembled on the main lifting seat 521 and the auxiliary lifting seat 522 and are respectively connected to the corresponding sliding brackets 532.

[0124] The attitude adjustment mechanism 535 includes a drive gear 5351, a transmission rack 5352, and a worm gear 5353 and a worm 5354 that maintain the matching combination. The transmission rack 5352 is fixedly connected to the sliding bracket 532. The worm gear 5353 and the worm 5354 are rotatably mounted on the main lifting seat 521 and the auxiliary lifting seat 522. The drive gear 5351 is coaxially fixedly connected to the worm gear 5353 and meshes with the transmission rack 5352.

[0125] The fixed bracket 531 ensures that the guide wheel 533 is stably assembled on the main lifting seat 521 and the auxiliary lifting seat 522, while the sliding bracket 532 can drive the clamping plate 534 on it to be adjusted in the horizontal direction. When the clamping plate 534 extends to be flush with the guide wheel 533, it can clamp the side of the profile and then effectively cut it. When the clamping plate 534 is in the retracted position with the sliding bracket 532, only the guide wheel 533 is in contact with the side of the profile, which can provide guidance for the transmitted profile and prevent it from being deviated.

[0126] When the attitude adjustment mechanism 535 is running, the worm gear 5354 drives the worm wheel 5353 and the drive gear 5351 to operate stably, which in turn drives the transmission rack 5352 and the sliding bracket 532 to achieve horizontal telescopic movement. The combination of the worm gear 5354 and the worm wheel 5353 also has a one-way self-locking characteristic, which prevents the drive gear 5351 from operating ineffectively and causing the transmission rack 5352, the sliding bracket 532, and the clamping plate 534 to undergo ineffective displacement, thereby improving the stability of the action on the profile.

[0127] To ensure that the guide clamping mechanisms 53 on each main lifting seat 521 and auxiliary lifting seat 522 always maintain synchronous adjustment of their posture, the following technical solution is provided.

[0128] The guide clamping mechanism 53 also includes an adjusting motor D5361, a second spline shaft D5362, a drive shaft C5363, a drive shaft D5364, and a second spline shaft E5365. The second spline shaft D5362 is arranged perpendicular to the traveling beam seat 511 and is poweredly connected to the adjusting motor D5361. A drive bevel gear E5114 is rotatably mounted on the traveling beam seat 511 and is slidably inserted with the second spline shaft D5362. The drive shaft C5363 is rotatably mounted in the traveling beam seat 511 and is arranged along the length direction of the traveling beam seat 511. A drive bevel gear E5366 is fixedly connected to the drive shaft C5363 and is meshed with the drive bevel gear E5114.

[0129] During the operation of the traveling beam seat 511 and its components, the power of the regulating motor D5361 can always drive the transmission shaft C5363 to operate stably through the combination of the second spline shaft D5362, the drive bevel gear E5114, and the transmission bevel gear E5366.

[0130] The drive shaft D5364 is rotatably mounted on the travel beam seat 511 and arranged in the vertical direction. The drive shaft C5363 is fixedly connected to the drive bevel gear e5367, and the drive shaft D5364 is fixedly connected to the drive bevel gear e5368, which meshes with the drive bevel gear e5367. The second spline shaft E5365 is coaxially fixedly connected to the worm gear 5354 provided on the auxiliary lifting seat 522 and is slidably inserted into both the drive shaft D5364 and the worm gear 5354 provided on the main lifting seat 521.

[0131] The rotating drive shaft C5363 can drive the drive shaft D5364 to operate stably through the combination of drive bevel gear e5367 and transmission bevel gear e5368. During the lifting and lowering movement of the main lifting seat 521 and the auxiliary lifting seat 522, the power of the drive shaft D5364 can always drive the two sets of worm gears 5354 to operate stably through the second spline shaft E5365, and drive the corresponding worm wheel 5353 and drive gear 5351 to operate stably, thereby realizing the synchronous opening and closing adjustment of the sliding bracket 532 and the clamping plate 534 in the guide clamping mechanism 53.
