Description

Technical Field

[0001] The invention belongs to the field of laser processing equipment, and in particular relates to H-shaped profile cutting equipment and a production line. Background Art

[0002] In the field of modern engineering construction and mechanical manufacturing, T-steel is widely used in building stable structures and transferring loads due to its unique structure and mechanical properties. In addition, due to the problems of poor precision and low efficiency in the traditional T-steel production method, it is difficult to meet the current stringent requirements of the manufacturing industry for high quality and high production capacity. H-steel itself has a reasonable structure and excellent material, and has become an ideal parent material for processing T-steel. At the same time, given the continuous increase in the manufacturing industry's demands for processing accuracy and efficiency, laser cutting technology is becoming increasingly popular in the processing of H-steel into T-steel and other application scenarios due to its high precision, narrow incision, low heat-affected zone and other characteristics.

[0003] At present, the laser cutting equipment commonly used in the market for processing H-shaped steel into T-shaped steel often adopts a structure in which the H-shaped steel is fixed, and the laser cutting head can move horizontally and linearly along the H-shaped steel to be processed along with the crossbeam, and mainly relies on the horizontal linear movement of the laser cutting head to realize the corresponding cutting action. For example, the large-size steel laser cutting equipment provided by the Chinese patent with publication number CN118989628A discloses a structure in which the H-shaped steel is first fixed and placed on the support structure between the two side beds, and then the crossbeam slide is used to drive the laser cutting head to move horizontally and linearly to perform laser cutting processing on the H-shaped steel. Moreover, when the processed H-shaped steel is a long profile, in order to ensure the processing accuracy and stability of the profile, and to avoid deformation, vibration and other problems of the long profile during the processing due to factors such as gravity and cutting force, it is generally arranged under the H-shaped steel with multiple groups of support structures, and the weight of the H-shaped steel is evenly carried by the multiple groups of support structures, so as to reduce the sagging deformation caused by gravity, so that it can maintain the correct shape and position during processing, thereby improving the processing accuracy and ensuring that the processed long profile meets the quality standards and design requirements.

[0004] However, only setting up a support structure cannot completely avoid the above problems, especially when the H-beam has been deformed. The entire cutting process will still be affected by factors such as poor flatness of the material plate surface and large stress deformation, resulting in large processing errors. Moreover, although the shape and path of the processed profile can be planned in advance through technologies such as laser scanning, it often requires high-precision scanning equipment and complex algorithm support, which leads to high equipment costs. At the same time, once the scanning equipment fails or the accuracy decreases, the acquired data will be biased, and the cutting path planned based on these deviation data is naturally difficult to guarantee accuracy. In addition, even if the preliminary planning is accurate, in the actual cutting process, the cutting heat will cause the internal stress of the H-beam to be redistributed, resulting in new deformation. The original planned path may no longer be suitable, which will ultimately affect the cutting quality and processing accuracy, so more effective solutions need to be further explored. Summary of the invention

[0005] The purpose of the present invention is to propose and design an H-shaped profile cutting equipment and production line to address the problem that existing laser cutting equipment cannot take into account both equipment cost and processing accuracy when processing long profiles such as H-shaped steel, and to enable it to overcome the above-mentioned problem and have high cost performance while having high processing accuracy.

[0006] In order to achieve the above-mentioned purpose, on the one hand, the present invention provides an H-shaped profile cutting device, including a base, at least one conveying unit is arranged on the upper end of the base, side beds are arranged on both sides of the base, a crossbeam is commonly installed on the upper ends of the side beds on both sides for horizontal sliding, a column is installed on one side of the crossbeam for horizontal sliding, a vertical lifting assembly is arranged at the lower end of the column, a laser head assembly is installed at the power output end of the vertical lifting assembly; the laser head assembly includes a fixed bottom plate, one side of the fixed bottom plate is fixedly connected to the power output end of the vertical lifting assembly, a laser head mounting frame is installed on the other side of the fixed bottom plate for horizontal sliding, a horizontal floating mechanism is arranged between the laser head mounting frame and the fixed bottom plate, and the laser head mounting frame is installed with a centering clamping mechanism and a laser head body.

[0007] At this time, when the present invention is used to process the H-shaped profile, it can first use the conveying unit to convey the H-shaped profile to the specified position, and then move the laser head assembly to the corresponding position; then control the centering clamping mechanism to center-clamp the H-shaped profile, thereby ensuring that the laser head body can always be located at the center position of the H-shaped profile, so as to avoid the cutting trajectory of the laser head body deviating from the preset path, thereby meeting the precision requirement of the centering cutting of the workpiece; at the same time, when the laser head assembly moves along the length direction of the H-shaped profile (i.e., the conveying direction of the conveying unit) with the crossbeam, the present invention can, under the action of the horizontal floating mechanism, ensure that the laser head body and the centering clamping mechanism installed on the laser head mounting frame can float horizontally accurately and flexibly according to the direction of the H-shaped profile when a certain degree of deviation occurs in the conveying path of the H-shaped profile, thereby effectively avoiding the risk of deformation of the centering clamping mechanism and the workpiece due to excessive external force in this process, and greatly ensuring the stability of equipment operation and the accuracy of workpiece processing.

[0008] Furthermore, the horizontal floating mechanism includes floating baffles installed at both ends of the fixed base plate, and the floating baffles located at both ends of the fixed base plate are relatively arranged on the left and right sides of the laser mounting frame; a horizontal elastic element is installed on the inner side of the floating baffle, and the end of the horizontal elastic element away from the corresponding floating baffle is in contact with the laser head mounting frame. At this time, after the laser head body and the centering clamping mechanism complete the centering clamping operation, even if the conveying path of the H-shaped profile is deflected to a certain extent, it can achieve the horizontal floating of the laser mounting frame on the fixed base plate through the cooperation of the horizontal elastic element and the floating baffle, that is, the horizontal floating of the laser mounting frame on the crossbeam is achieved. In this way, the risk of deformation of the centering clamping mechanism and the H-shaped profile due to excessive external force in this process is effectively avoided, and the stability of the equipment operation and the accuracy of workpiece processing are greatly guaranteed.

[0009] Furthermore, a horizontal rotary wheel 3 is provided at the position of the centering clamping mechanism for contacting the workpiece, and the horizontal rotary wheel 3 will directly contact the wing plate of the H-shaped profile during actual operation. In this way, when the centering clamping mechanism performs the centering clamping action on the H-shaped profile, the horizontal rotary wheel 3 can greatly reduce the friction between the centering clamping mechanism and the H-shaped profile by virtue of its own flexible rotation characteristics, so as to ensure that the laser head assembly can move horizontally smoothly, effectively avoid scratching the workpiece surface due to excessive friction, thereby ensuring the integrity of the workpiece surface and providing a high-quality foundation for subsequent processing procedures.

[0010] Furthermore, the laser head mounting frame includes a centering base plate and a laser head fixing plate arranged in parallel, one side of the centering base plate is horizontally slidably mounted on the fixing base plate, the left and right ends of the centering base plate are connected to the horizontal floating mechanism, the upper and lower ends of the centering base plate and the upper and lower ends of the laser head fixing plate are fixedly connected through connecting blocks, and the centering clamping mechanism is mounted on the centering base plate, and the laser head body is mounted on the laser head fixing plate. At this time, the centering base plate and the laser head fixing plate can form a stable frame structure, and effectively disperse various stresses generated during the laser cutting process, prevent the laser head mounting frame from being deformed due to uneven force, ensure the relative position accuracy of the laser head body and the centering clamping mechanism, and ensure the stability and accuracy of the cutting and centering operations.

[0011] Furthermore, the centering clamping mechanism is located between the centering bottom plate and the laser head fixing plate. Since the centering clamping mechanism is placed between the centering bottom plate and the laser head fixing plate, the space inside the laser head mounting frame is fully utilized, making the structure of the entire laser head mounting frame compact, reducing the floor space of the equipment, and improving space utilization, which is particularly suitable for work scenes with limited space.

[0012] Furthermore, each conveying unit includes two support frames arranged in parallel at the upper end of the base, and a material conveying channel is arranged between the two support frames; each support frame is provided with a transmission roller group, and each transmission roller group is transmission-connected to a rotating drive mechanism; each transmission roller group includes at least two transmission rollers arranged in parallel along the material conveying direction, and the middle part of the transmission roller is rotatably installed on the corresponding support frame, one end of the transmission roller extends into the material conveying channel and is provided with a support roller, and the other end of the transmission roller extends out of the support frame and is transmission-connected to the rotating drive mechanism; the transmission rollers of the two transmission roller groups are arranged opposite to each other, and an avoidance gap is provided between the two opposite support rollers. At this time, on the one hand, the present invention can constrain the travel direction of the H-shaped profile through the cooperation of two support frames and the two side wing plates of the H-shaped profile to avoid the deviation of the H-shaped profile; support the web of the H-shaped profile through the support roller structure to ensure that the H-shaped profile has stable support during the transportation process, thereby avoiding sagging and deformation problems caused by gravity; on the other hand, the present invention can provide sufficient and uniform driving force through two parallel transmission roller groups and the two rotating drive mechanisms connected by them to ensure uniform speed transportation of the H-shaped profile and reduce jamming, and can also reserve operating space for the processing procedures through the avoidance gap between the support rollers, which is convenient for cutting, welding and other processing, that is, it ensures that the H-shaped profile can be smoothly cut into a T-shaped profile; at the same time, the two-end arrangement method adopted by the transmission roller in the present invention can also separate the transmission and support functions, thereby optimizing the overall structure.

[0013] Furthermore, in each conveying unit, there is only one support frame with at least one guide mechanism provided on the side facing the material conveying channel, and the material is guided by the guide mechanism during the material movement to ensure that the material can always move in a straight line along a preset route, thereby ensuring that the material can move smoothly along the conveying line and avoiding jamming during the conveying process.

[0014] Furthermore, the guide mechanism includes a fixed sleeve fixedly mounted on the support frame, a guide column is inserted in the fixed sleeve, one end of the guide column is extended out of the fixed sleeve and provided with a flange edge, the flange edge is located in the support frame and can abut against the fixed sleeve; the other end of the guide column is extended out of the fixed sleeve and provided with a guide plate, the guide plate is located in the material conveying channel; the other end of the guide column is extended out of the fixed sleeve and is also provided with a spring, the two ends of the spring respectively abut against the guide plate and the fixed sleeve. At this time, on the one hand, since the present invention installs the fixed sleeve on the support frame, it can be completely hidden inside the support frame, reducing its occupied space in the material conveying channel, thereby effectively ensuring the restraining effect of the support frame; on the other hand, the present invention can accurately guide the conveying direction of the long profile through the guide column that can be flexibly extended and retracted in the fixed sleeve, avoiding its deviation during the conveying process. Moreover, since a spring is sleeved on the guide column of the present invention, on the one hand, when the guide plate is squeezed by the material, the spring can absorb the impact force through its own elastic deformation to ensure the stable operation of the guide plate; on the other hand, after the material passes through, the elastic force of the spring can be used to quickly reset the guide plate to prepare for the next guidance, thereby ensuring that the long profiles always maintain a stable and accurate conveying path on the conveyor line, thereby improving the conveying efficiency and processing accuracy.

[0015] Further, the guide plate includes a first guiding sloped portion, a plane portion, and a second guiding sloped portion, which are sequentially arranged along the material advancing direction. The plane portion is a vertical surface parallel to the material advancing direction. The first guiding sloped portion gradually tilts toward the direction close to the fixed sleeve in the direction opposite to the material advancing direction. The second guiding sloped portion gradually tilts toward the direction close to the fixed sleeve in the material advancing direction. At this time, when the H-shaped profile passes through the guide mechanism, it will first contact the first guiding sloped portion, and under the guidance of the first guiding sloped portion, it will gradually move closer to the center position of the material conveying channel, thereby preliminarily calibrating the initial position of the H-shaped profile and reducing the unstable conveying caused by the placement deviation; then, after the H-shaped profile passes through the preliminary guidance of the first guiding sloped portion, it will contact the plane portion; the plane portion can limit the H-shaped profile, so that the H-shaped profile can move forward along the conveying direction in a stable posture. Conversely, when the H-shaped profile needs to be retreated, it can first be preliminarily guided by the second guiding sloped portion, and then limited by the plane portion.

[0016] Furthermore, each conveying unit is provided with at least one horizontal clamping mechanism and at least one vertical clamping mechanism along the material conveying direction; the material is vertically clamped by the vertical clamping mechanism to achieve vertical fixation of the material, thereby ensuring that it can meet the material processing accuracy requirements.

[0017] Furthermore, the horizontal clamping mechanism includes a mounting seat 1 and a mounting seat 2, and the mounting seat 1 and the mounting seat 2 are respectively installed on two supporting frames; a horizontal rotary wheel 1 is rotatably installed on the mounting seat 1, a horizontal linear motion actuator 1 is installed on the mounting seat 2, a horizontal top plate is installed at the output end of the horizontal linear motion actuator 1, a horizontal rotary wheel 2 is rotatably installed on the horizontal top plate, the horizontal rotary wheel 2 is arranged opposite to the corresponding horizontal rotary wheel 1, and the horizontal rotary wheel 2 can approach or move away from the horizontal rotary wheel 1 under the action of the horizontal linear motion actuator 1 to achieve the corresponding horizontal clamping action or relaxation action.

[0018] Furthermore, the vertical clamping mechanism includes a mounting seat three, which is installed on any supporting frame; a horizontal linear motion actuator two is provided at the upper end of the mounting seat three, and the output motion direction of the horizontal linear motion actuator two is perpendicular to the material conveying direction; a vertical linear motion actuator is installed at the output end of the horizontal linear motion actuator two, and a vertical pressure plate is installed at the output end of the vertical linear motion actuator, and a universal wheel is provided at the lower end of the vertical pressure plate, and can move downward under the action of the vertical linear motion actuator, thereby pressing materials such as H-shaped steel to prevent deformation and misalignment after cutting.

[0019] Furthermore, two material guide slopes are symmetrically arranged on the left and right sides of the feed end of the material conveying channel, and the two material guide slopes gradually tilt inward along the material forward direction. At this time, the feed end of the material conveying channel will form a trumpet-shaped feed port structure with a gradually narrowing diameter along the feed direction under the action of the material guide slopes on both sides, and based on the trumpet, on the one hand, the present invention can greatly improve the fault tolerance of feeding, so that materials such as H-shaped profiles do not need to be particularly accurately positioned when initially placed, and even if the position is slightly deviated, they can enter the feeding area along the spacious opening, thereby greatly reducing the difficulty of loading and improving operating efficiency; on the other hand, as materials such as H-shaped profiles move forward, the present invention can play a gathering role through the gradually contracting trumpet-shaped structure, gradually guiding the H-shaped profile to a precise position, so that it can move forward on the conveying line accurately, thereby effectively avoiding problems such as conveying jams and collisions with equipment caused by position deviations of H-shaped profiles during the conveying process, and ensuring the stability and smoothness of the conveying process. At the same time, this unique shape design can also adapt to H-shaped profiles of different specifications. No matter whether the profile is larger or smaller in width, it can be fed smoothly with the help of the trumpet-shaped feed port structure, thereby enhancing the compatibility of the entire conveyor line with a variety of profiles and broadening the scope of application of the equipment.

[0020] Furthermore, a second material guide slope is provided at the lower part of the feed end of the material conveying channel, and the second material guide slope gradually slopes downward in the direction opposite to the material forward direction. At this time, the present invention can use the height difference of the second material guide slope to cleverly slow down the speed at which the material enters the conveying line, avoid the material from strongly colliding with the conveying equipment due to entering too quickly, and ensure the safe and stable operation of the conveying line.

[0021] Furthermore, a sensor is provided at the discharge end of the material conveying channel to monitor in real time whether the material has arrived at the discharge end smoothly. Once it is detected that the material is in place, a signal is immediately sent to the control system of the entire equipment, and the signal is used to remind the laser head assembly to operate, thereby greatly improving the automation level and operation efficiency of the production line, reducing manual intervention, reducing the probability of errors, and ensuring efficient and stable operation of the production process.

[0022] On the other hand, the present invention provides an H-shaped profile cutting production line, which includes the above-mentioned H-shaped profile cutting equipment, wherein the feeding end of the H-shaped profile cutting equipment is provided with a loading device, and the discharging end of the H-shaped profile cutting equipment is provided with a discharging device.

[0023] It can be seen from the above technical solutions that the present invention has the following advantages: 1. When the present invention is used to process an H-shaped profile, the centering clamping mechanism can be used to center the H-shaped profile, thereby ensuring that the laser head body can always be located at the center of the H-shaped profile, so as to prevent the cutting trajectory of the laser head body from deviating from the preset path, thereby meeting the precision requirements of the centering cutting of the workpiece; 2. When the laser head assembly moves along the length direction of the H-shaped profile (i.e., the conveying direction of the conveying unit) with the crossbeam, the present invention can ensure that the laser head body and the centering clamping mechanism installed on the laser head mounting frame can accurately and flexibly float in the horizontal direction according to the direction of the H-shaped profile under the action of the horizontal floating mechanism when the conveying path of the H-shaped profile deflects to a certain extent, thereby effectively avoiding the risk of deformation of the centering clamping mechanism and the workpiece due to excessive external force in this process, and greatly ensuring the stability of equipment operation and the accuracy of workpiece processing; 3. The centering base plate and the laser head fixing plate in the present invention can form a stable frame structure and effectively disperse various stresses generated during the laser cutting process, prevent the laser head mounting frame from being deformed due to uneven force, ensure the relative position accuracy of the laser head body and the centering clamping mechanism, and ensure the stability and accuracy of the cutting and centering operations; 4. The present invention places the centering clamping mechanism between the centering bottom plate and the laser head fixing plate, making full use of the space inside the laser head mounting frame, making the structure of the entire laser head mounting frame compact, reducing the floor space of the equipment, and improving space utilization, which is particularly suitable for work scenes with limited space; 5. The present invention can constrain the traveling direction of the H-shaped profile through the cooperation of two support frames and the two side wing plates of the H-shaped steel, as well as various guide structures arranged at the support frames: guide mechanism, guide slope 1, guide slope 2, horizontal clamping mechanism, and vertical clamping mechanism, to avoid the deviation of the H-shaped profile; the web of the H-shaped profile is supported by the transmission roller structure to ensure that the H-shaped profile has stable support during the transportation process, thereby avoiding sagging and deformation problems caused by gravity, so as to ensure the cutting accuracy of the H-shaped profile; 6. The present invention can provide sufficient and uniform driving force through two parallel transmission roller groups and the two rotating drive mechanisms connected by them to ensure uniform speed transportation of profiles and reduce jamming. It can also reserve operating space for processing procedures through the avoidance gap between the supporting rollers, which is convenient for cutting, welding and other processing, and ensures that H-shaped profiles can be smoothly cut into T-shaped profiles.

DETAILED DESCRIPTION

[0027] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0028] Embodiment 1 like Figures 1 to 11 As shown, this embodiment 1 provides an H-shaped profile cutting device, which includes a base 1, and at least one conveying unit 10 is arranged on the upper end of the base 1. When at least two conveying units 10 are arranged above it, all the conveying units 10 can be arranged in parallel along the width direction of the base 1 to ensure that all materials can be conveyed in parallel.

[0029] Specifically, Figure 6As shown, the conveying unit 10 includes two support frames 4 arranged in parallel at the upper end of the base 1 along the width direction of the base 1, and a material conveying channel 9 for conveying materials is arranged between the two support frames 4, and two material guide slopes 2 are symmetrically arranged on the left and right sides of the feed end of the material conveying channel 9, and the two material guide slopes 2 are gradually inclined inward along the material forward direction, and a trumpet-shaped feed port structure with a gradually narrowing diameter along the feed direction is formed at the feed end of the material conveying channel 9, and based on the trumpet, on the one hand, the present invention can greatly improve the fault tolerance of feeding. The rate is high, so that H-shaped profiles and other materials do not need to be particularly accurately positioned when they are initially placed. Even if the position is slightly deviated, they can enter the feeding area through the spacious opening, thereby greatly reducing the difficulty of loading and improving operating efficiency; on the other hand, as H-shaped profiles and other materials move forward, the present invention can play a gathering role through the gradually closing trumpet-shaped structure, gradually guiding the H-shaped profile to a precise position, so that it can move forward accurately on the conveying unit 10, thereby effectively avoiding the problems of conveying jams and collisions with equipment caused by position deviations during the conveying process of the H-shaped profile, and ensuring the stability and smoothness of the conveying process. At the same time, this unique shape design can also adapt to H-shaped profiles of different specifications. Whether it is a larger or smaller H-shaped profile, it can be smoothly fed with the help of the trumpet-shaped feed port structure, thereby enhancing the compatibility of the entire conveying unit 10 with a variety of profiles and broadening the scope of application of the equipment. In addition, as a preference, the present invention further provides a material guide slope 23 at the lower portion of the feed end of the material conveying channel 9, and the material guide slope 23 is gradually inclined downward in a direction opposite to the material forward direction. In this way, the height difference of the material guide slope 23 is utilized to cleverly slow down the speed at which the material enters the conveying unit 10, thereby preventing the material from colliding violently with the conveying unit 10 due to entering too quickly, thereby ensuring the safe and stable operation of the conveying unit 10.

[0030] The discharge end of the material conveying channel 9 is provided with an in-place sensor, and the in-place sensor is used to monitor in real time whether the material has arrived at the discharge end smoothly. Once it is detected that the material is in place, a signal is immediately sent to the control system of the entire equipment, and the signal is used to remind the laser head assembly 35 to operate, thereby greatly improving the automation level and operation efficiency of the production line, reducing manual intervention, reducing the probability of error, and ensuring efficient and stable operation of the production process.

[0031] Each support frame 4 is provided with a transmission roller group, and each transmission roller group is transmission-connected with a rotary drive mechanism 5. Specifically, each transmission roller group includes at least two transmission rollers 31 arranged in parallel along the material conveying direction, and the middle part of each transmission roller 31 is rotatably mounted on the corresponding support frame 4 through bearings and other components, and one end of each transmission roller 31 extends into the material conveying channel 9 and is provided with a support roller 32, and contacts and supports the H-shaped profile and other materials to be conveyed through the support roller 32 to achieve the corresponding conveying function, and when the material is an H-shaped profile, the support roller 32 directly contacts the web of the H-shaped profile. The other end of each transmission roller 31 extends out of the support frame 4 and is transmission-connected with the rotary drive mechanism 5, and the rotary drive mechanism 5 can adopt a combination of a drive motor and a chain transmission mechanism, that is, it can adopt a structure in which the drive motor is first transmission-connected with any one of the transmission rollers 31 in the transmission roller group, and then all the transmission rollers 31 in the transmission roller group are transmission-connected together through the chain transmission mechanism.

[0032] At the same time, in the process of setting the above two transmission roller groups, in order to ensure the stability of material movement, the present invention sets the transmission rollers 31 in the above two transmission roller groups one by one, and leaves an avoidance gap 33 between the two opposite support rollers 32. At this time, on the one hand, the present invention can constrain the travel direction of the H-shaped profile through the cooperation of the two support frames 4 and the two side wing plates of the H-shaped profile to avoid the deviation of the H-shaped profile; the web of the H-shaped profile is supported by the support roller 32 structure to ensure that the H-shaped profile has stable support during the transportation process, thereby avoiding the sagging and deformation problems caused by gravity; on the other hand, the present invention can provide sufficient and uniform driving force through two parallel transmission roller groups and the two rotating drive mechanisms 5 connected by them to ensure uniform transportation of the profile and reduce jamming, and can also reserve operating space for the processing process through the avoidance gap 33 between the support rollers 32, which is convenient for cutting, welding and other processing, that is, to ensure that the H-shaped profile can be smoothly cut into a T-shaped profile.

[0033] In addition, in order to ensure the processing accuracy of materials such as H-shaped profiles, the present invention also provides multiple vertical clamping mechanisms 8 on the support frame 4 of the same conveying unit 10, and multiple horizontal clamping mechanisms 11 between the two support frames 4 of the same conveying unit 10.

[0034] Specifically, Fig. 9As shown, the vertical clamping mechanism 8 includes a mounting seat 3 26, and the mounting seat 3 26 is mounted on any one of the support frames 4, and a horizontal linear motion actuator 2 22 is arranged at the upper end of the mounting seat 3 26, and the output motion direction of the horizontal linear motion actuator 2 22 is perpendicular to the material conveying direction. A vertical linear motion actuator 25 is installed at the output end of the horizontal linear motion actuator 22 through a support 23, and a vertical pressing plate 27 is installed at the output end of the vertical linear motion actuator 25, and a universal wheel 24 is arranged at the lower end of the vertical pressing plate 27. In this way, during the conveying process of materials such as H-shaped profiles, the present invention can, on the one hand, vertically clamp the H-shaped profiles and other materials through the vertical clamping mechanism 8 to prevent them from being deformed and misaligned after cutting; on the other hand, the horizontal linear motion actuator 22 can control the vertical linear motion actuator 25 and the components installed at the vertical linear motion actuator 25 to avoid affecting the cutting operation of materials such as H-shaped profiles.

[0035] like Figure 7 , Figure 8 As shown, the horizontal clamping mechanism 11 includes a mounting seat 12 and a mounting seat 26, and the mounting seat 12 and the mounting seat 26 are respectively mounted on two support frames 4 of the same conveying unit 10. In addition, the present invention also rotatably mounts a horizontal rotary wheel 13 on the mounting seat 12, and a horizontal linear motion actuator 1 28 is fixedly mounted on the mounting seat 26, and the output motion direction of the horizontal linear motion actuator 1 28 is perpendicular to the material conveying direction. At the same time, a horizontal top plate 29 is mounted on the output end of the horizontal linear motion actuator 1 28, and a horizontal rotary wheel 2 30 is rotatably mounted on the horizontal top plate 29, and the horizontal rotary wheel 2 30 is arranged opposite to the corresponding horizontal rotary wheel 13, so that the horizontal rotary wheel 2 30 can approach or move away from the horizontal rotary wheel 13 under the action of the horizontal linear motion actuator 1 28 to achieve the corresponding horizontal clamping action or relaxation action, so that it can horizontally clamp H-shaped profiles and other materials during the conveying process of H-shaped profiles and other materials.

[0036] In addition, the present invention also provides at least one guide mechanism 7 on any support frame 4 of the same conveying unit 10, and when the number of the guide mechanisms 7 is 2 or more, all the guide mechanisms 7 can be evenly spaced and arranged in parallel on the side of the corresponding support frame 4, so that the guide mechanism 7 guides the material during the material movement process to ensure that the material can always move in a straight line along the preset route, thereby ensuring that the material can move smoothly along the conveying line and avoid jamming during the conveying process. Specifically, Fig.10As shown, the guide mechanism 7 includes a fixed sleeve 15 fixedly installed in the support frame 4, a guide column 14 is inserted in the fixed sleeve 15, and a flange 18 is arranged after one end of the guide column 14 extends out of the fixed sleeve 15, and the flange 18 is located in the support frame and can abut against the fixed sleeve 15; the other end of the guide column 14 extends out of the fixed sleeve 15 and is located in the material conveying channel 9, and the other end of the guide column 14 extends out of the fixed sleeve 15 and is provided with a guide plate 17. The guide plate 17 includes a guide slope portion 19, a plane portion 20, and a guide slope portion 21 which are sequentially arranged along the material advancing direction, and the plane portion 20 is a vertical surface parallel to the material advancing direction and is fixedly connected to the end of the guide column 14; the guide slope portion 19 gradually tilts toward the direction close to the fixed sleeve 15 in the direction opposite to the material advancing direction, and the guide slope portion 21 gradually tilts toward the direction close to the fixed sleeve 15 in the material advancing direction. Meanwhile, the other end of the guide column 14 is extended out of the fixing sleeve 15 and is sleeved with a spring 16 , and two ends of the spring 16 abut against the guide plate 17 and the fixing sleeve 15 respectively.

[0037] At this time, on the one hand, since the present invention installs the fixed sleeve 15 on the support frame 4, it can be completely hidden inside the support frame 4, reducing its occupied space in the material conveying channel 9, thereby effectively ensuring the restraining effect of the support frame 4; on the other hand, the present invention can accurately guide the conveying direction of the long profile through the guide column 14 that can be flexibly extended and retracted in the fixed sleeve 15, and the guide plate 17 arranged at the end of the guide column 14, so as to avoid its deviation during the conveying process, that is, when the H-shaped profile and other long profiles pass through the guide mechanism 7, the H-shaped profile will first contact the guide inclined portion 19, and under the guidance of the guide inclined portion 19, gradually move closer to the center position of the material conveying channel 9, thereby achieving the purpose of preliminary calibration of the initial position of the H-shaped profile, reducing the unstable conveying caused by placement deviation; then, after the H-shaped profile passes through the preliminary guidance of the guide inclined portion 19, it will contact the plane portion 20; the plane portion 20 can limit the H-shaped profile in the horizontal direction, so that the H-shaped profile can move along the conveying direction in a stable posture. On the contrary, when the H-shaped profile needs to be retreated, the H-shaped profile can be initially guided by the second guiding inclined surface portion 21, and then the H-shaped profile can be limited by the flat surface portion 20. In addition, since the guide column 14 of the present invention is sleeved with a spring 16, on the one hand, when the guide plate 17 is squeezed by the material, it can absorb the impact force through its own elastic deformation to ensure the stable operation of the guide plate 17; on the other hand, after the material passes, the elastic force of the spring 16 can be used to quickly reset the guide plate 17 to prepare for the next guidance, ensuring that the H-shaped profile always maintains a stable and accurate conveying path on the conveying line, thereby improving the conveying efficiency and processing accuracy.

[0038] like Figure 1 As shown, the base 1 is provided with side beds 34 on both sides, and the upper ends of the side beds 34 on both sides are commonly horizontally slidably mounted with a crossbeam 37, a column 36 is horizontally slidably mounted on one side of the crossbeam 37, a vertical lifting assembly 38 is provided at the lower end of the column 36, and a laser head assembly 35 is mounted at the power output end of the vertical lifting assembly 38. At the same time, the horizontal sliding direction of the crossbeam 37 is parallel to the material conveying direction of the conveying unit 10, and the horizontal sliding direction of the column 36 is perpendicular to the material conveying direction of the conveying unit 10, thereby ensuring that the laser head assembly 35 can move in the material conveying direction, in the horizontal direction perpendicular to the material conveying direction, and in the vertical direction.

[0039] like Figure 2 As shown, the laser head assembly 35 includes a laser head mounting frame and a fixed base plate 41. One side of the fixed base plate 41 is used to be installed on the power output end of the vertical lifting assembly 38, and the other side of the fixed base plate 41 is used to horizontally slide and mount the laser head mounting frame through a linear guide pair. At the same time, a horizontal floating mechanism is arranged between the fixed base plate 41 and the laser head mounting frame. The horizontal floating mechanism includes floating baffles 42 installed on the left and right ends of the fixed base plate 41, and the floating baffles 42 at both ends of the fixed base plate 41 are relatively arranged on the left and right sides of the laser mounting frame; a horizontal elastic element 43 is installed on the inner side of the floating baffle 42, and the end of the horizontal elastic element 43 away from the floating baffle 42 connected to it is abutted against the laser head mounting frame.

[0040] The laser head mounting frame includes a centering base plate 44 and a laser head fixing plate 40 arranged in parallel. One side of the centering base plate 44 is horizontally slidably connected to the fixing base plate 41, and both ends of the centering base plate 44 are respectively abutted against corresponding horizontal elastic elements 43; a centering clamping mechanism 45 is installed on the other side of the centering base plate 44, and the structure of the centering clamping mechanism 45 can adopt any one of the common centering clamping mechanisms 45 on the market.

[0041] For example: 1. Gear rack structure, in this case, the centering clamping mechanism 45 includes a gear 50 rotatably mounted on the centering bottom plate 44 at the laser head mounting frame, and the outer side of the gear 50 is meshed with a rack 1 51 and a rack 2 52 at the same time, and the rack 1 51 and the rack 2 52 are arranged in parallel and are both horizontally slidably mounted on the laser head mounting frame through a linear guide pair. At the same time, the rack 1 51 in this embodiment 1 is fixedly connected to the clamping arm 1 46, and the rack 2 52 is fixedly connected to the clamping arm 2 49; the clamping arm 1 46 and the clamping arm 2 49 are relatively arranged on both sides of the gear 50, and the clamping arm 1 46 and the clamping arm 2 49 are symmetrically arranged on both sides of the laser head body 48. The rack 1 51 or the rack 2 52 in this embodiment 1 is transmission-connected with a linear motion actuator such as a cylinder or a hydraulic cylinder, or the clamping arm 1 46 or the clamping arm 2 49 is transmission-connected with a linear motion actuator such as a cylinder or a hydraulic cylinder, or the gear 50 is transmission-connected with a rotary motion actuator such as a motor. In this way, when it is necessary to perform a centering clamping action, it can directly drive the rack 1 51 or the rack 2 52 to move linearly through a linear motion actuator, or drive the gear 50 to rotate through a rotary motion actuator, and use the meshing transmission of the gear 50 with the rack 1 51 and the rack 2 52 to control the rack 1 51 and the rack 2 52 to perform opposite and synchronous linear motion. At this time, the clamping arm 1 46 connected to the rack 1 51 and the clamping arm 2 49 connected to the rack 2 52 will move closer or farther at the same speed, so as to accurately clamp the workpiece at the center position, ensure the centering accuracy, and meet the high-precision processing requirements.

[0042] 2. Ball screw structure. In this case, the centering clamping mechanism 45 includes a screw 53 rotatably mounted on the centering bottom plate 44 at the laser head mounting frame, and the screw 53 is connected to a rotary motion actuator such as a motor. Moreover, the two ends of the screw 53 are respectively provided with a threaded segment 1 and a threaded segment 2, and the threaded segment 1 and the threaded segment 2 have opposite rotation directions; the threaded segment 1 is threadedly connected to a nut seat 1, the nut seat 1 is fixedly connected to a clamping arm 1 46, and the nut seat 1 and / or the clamping arm 1 46 are horizontally slidably mounted on the laser head mounting frame through a linear guide pair; the threaded segment 2 is threadedly connected to a nut seat 2 54, the nut seat 2 54 is fixedly connected to a clamping arm 2 49, and the nut seat 2 54 and / or the clamping arm 2 49 are horizontally slidably mounted on the laser head mounting frame through a linear guide pair. When a centering clamping action is required, the lead screw 53 can be driven to rotate through a rotary motion actuator, and the clamping arm 1 46 and the clamping arm 2 49 can be driven to make opposite linear motions along the axis of the lead screw 53 through the nut seat 1 and the nut seat 2 54 which are respectively threadedly matched on the threaded segment 1 and the threaded segment 2 which rotate in opposite directions, thereby achieving the purpose of moving to the middle or to both sides at the same time, that is, achieving the purpose of centering clamping.

[0043] 3. Linkage mechanism. In this case, the centering clamping mechanism 45 includes a rotating shaft 56 rotatably mounted on the laser head mounting frame. The outer side of the rotating shaft 56 is hinged with a link 1 55 and a link 2 57 at the same time, and the hinge points of the link 1 55 and the rotating shaft 56 and the hinge points of the link 2 57 and the rotating shaft 56 are symmetrically arranged on both sides of the rotating shaft 56. In addition, the link 1 55 is hinged with a clamping arm 1 46, and the link 2 57 is hinged with a clamping arm 2 49. The clamping arm 1 46 and the clamping arm 2 49 are both horizontally slidably mounted on the laser head mounting frame through a linear guide pair, and the clamping arm 1 46 and the clamping arm 2 49 are relatively arranged on both sides of the rotating shaft 56; at the same time, the clamping arm 1 46 or the clamping arm 2 49 is transmission-connected with a linear motion actuator such as a cylinder or a hydraulic cylinder, or the rotating shaft 56 is transmission-connected with a rotary motion actuator such as a motor. Moreover, when a centering clamping action is required, it can directly drive the clamping arm 1 46 or the clamping arm 2 49 to move linearly through a linear motion actuator, or drive the rotating shaft 56 to rotate through a rotary motion actuator, and use the connecting rod structure formed between the rotating shaft 56 and the connecting rod 1 55, the connecting rod 2 57, the clamping arm 1 46, and the clamping arm 2 49 to control the clamping arm 1 46 and the clamping arm 2 49 to move closer or farther at the same speed, thereby accurately clamping the workpiece in the center position, ensuring the centering accuracy and meeting the high-precision processing requirements.

[0044] Furthermore, as a preferred embodiment, the present embodiment 1 can be provided with a horizontal rotary wheel 3 47 at the lower part of the clamping arm 1 46 and the lower part of the clamping arm 2 49, and the contact between the corresponding clamping arm and the workpiece can be achieved through the horizontal rotary wheel 3 47 during the actual working process. In this way, when the clamping arm 1 46 and the clamping arm 2 49 perform a centering clamping action on the workpiece, the horizontal rotary wheel 3 47 can greatly reduce the friction between the clamping arm and the workpiece by virtue of its own flexible rotation characteristics, so as to ensure that the workpiece can move horizontally smoothly, effectively avoid scratching the surface of the workpiece due to excessive friction, thereby ensuring the integrity of the workpiece surface and providing a high-quality foundation for subsequent processing procedures. At the same time, in order to prevent the clamping arm 1 46 and the clamping arm 2 49 from colliding with the laser head body 48, the present embodiment 1 can also relatively arrange the clamping arm 1 46 and the clamping arm 2 49 on both sides of the laser head fixing plate 40, and make the width of the laser head fixing plate 40 greater than the width of the laser head body 48.

[0045] The laser head fixing plate 40 is arranged on the front side of the centering clamping mechanism 45, that is, the centering clamping mechanism 45 is located between the centering base plate 44 and the laser head fixing plate 40; and the upper and lower ends of the laser head fixing plate 40 are fixedly connected to the upper and lower ends of the centering base plate 44 through connecting blocks 39, and the laser head body 48 is installed on the side of the laser head fixing plate 40 away from the centering base plate 44.

[0046] Based on this, when using the first embodiment of the present invention to perform a cutting operation on an H-shaped profile, that is, when using the first embodiment of the present invention to cut an H-shaped profile into two T-shaped profiles, when the workpiece moves to the bottom of the laser head body 48, it can first control the centering clamping mechanism 45 to act, that is, control the centering clamping mechanism 45 to center clamp the H-shaped profile located between the clamping arm 1 46 and the clamping arm 2 49; and then control the laser head body 48 to perform a cutting action, thereby ensuring that the laser head body 48 can always be located at the center of the workpiece, avoiding the cutting trajectory of the laser head body 48 from deviating from the preset path, and thus meeting the precision requirements of the centering cutting of the workpiece. In addition, in this process, the horizontal elastic element 43 and the floating baffle 42 are used to realize the horizontal floating of the laser mounting frame on the fixed bottom plate 41, that is, the horizontal floating of the laser mounting frame on the crossbeam of the laser cutting equipment is realized, thereby ensuring the stability of the equipment operation and the accuracy of the workpiece processing.
