Description

Technical Field

[0001] The invention relates to the technical field of wire groove laser processing, and in particular to a galvanized metal wire groove laser processing system adopting a segmented positioning structure. Background Art

[0002] Galvanized cable trunking is a metal product widely used in construction, electrical installation and other fields. In order to enhance its corrosion resistance and extend its service life, the surface of such cable trunking is often galvanized.

[0003] In the production and manufacturing process of U-shaped galvanized wire duct, laser cutting technology is widely used due to its advantages of high precision, high efficiency, non-contact processing and the ability to cut complex shapes. Laser cutting can be used to perform fixed-length cutting, hole opening, corner cutting and other processing operations on the wire duct to meet different installation and use requirements.

[0004] Before the wire trough is transported to the cutting station and prepared for laser cutting, the traditional process usually relies on clamps set on both sides and close to each other to synchronously limit the lateral displacement of the wire trough. The original intention of this method is to prevent the wire trough body from vibrating or deflecting due to external disturbances or its own thermal deformation during processing. However, this limiting method that relies solely on clamping on both sides has limitations. The clamps only exert a restraining force on both sides of the wire trough. When the laser beam acts on the wire trough and causes its local material to soften slightly, the excessive clamping force of the clamps on both sides will cause uneven extrusion of the softened wire trough, causing it to undergo plastic deformation and affect the final dimensional accuracy. Summary of the Invention

[0005] In response to the above-mentioned shortcomings of the prior art, the present invention provides a galvanized metal wire trough laser processing system with a segmented positioning structure, which can effectively solve the problem in the prior art that the clamping parts only exert a restraining force on both sides of the wire trough. When the laser beam acts on the wire trough and causes its local material to soften slightly, the excessive clamping force of the clamping parts on both sides will produce uneven extrusion on the softened wire trough, thereby causing it to undergo plastic deformation and affecting the final dimensional accuracy.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The present invention provides a galvanized metal trunking laser processing system using a segmented positioning structure, comprising:

[0008] Provide a plurality of mounting plate brackets;

[0009] Trunk body;

[0010] There are several limiting mechanisms, which are used to achieve the tight limiting work of the wire trough body;

[0011] A ring-shaped platform with a receiving groove on the inner wall is provided on the rear side wall of the mounting plate. A supporting tray connected to the mounting plate is also provided on the bracket. A laser cutting head for cutting the wire trough body is provided on the outer wall of the supporting tray.

[0012] Among them, a number of guide grooves are opened on both side walls of the receiving groove along the circumferential direction, and a support plate with a slide groove corresponding to the position of the guide groove is provided inside the receiving groove. A pressure roller is provided on the support plate and fits with the wire groove body. The setting of the pressure roller not only realizes the guiding function of the wire groove body during the movement, but also realizes the tight limiting work when the wire groove body is cut by the laser cutting head;

[0013] The limiting mechanism includes a mounting frame which is arranged below the wire trough body and fits against the side wall of the wire trough body.

[0014] Furthermore, an avoidance groove is provided on the side wall of the mounting frame and the mounting frame is connected to the support plate through a telescopic plate. Two driving members symmetrical along the front-to-back direction are provided inside the mounting frame, and a tightening member is provided on the end of the mounting frame away from the driving member.

[0015] Furthermore, a sliding block connected to the mounting frame through a compression spring is slidably provided inside the avoidance groove, and a side wall of the sliding block is provided with a guide roller whose outer wall is in contact with the wire groove body through a telescopic member.

[0016] Furthermore, the two driving members both include gears rotatably arranged inside the mounting frame, and racks sliding through the mounting frame are respectively engaged on both sides of the two gears, and the side walls of the two racks at two positions far away from each other are commonly connected to a linkage frame.

[0017] Furthermore, a push block is provided at the bottom end of the mounting frame, and a plurality of push plates are provided on the upper end surface of the push block. The plurality of push plates are slidably arranged inside the linkage frame, and the lower end surface of the push block is slidably arranged inside the slide groove through a square block.

[0018] Furthermore, the fastening member includes two support frames which are symmetrically arranged in an upper and lower manner and respectively connected to corresponding racks. The support frames are slidably arranged inside the mounting frame. In the initial state, the upper and lower support frames do not contact the wire trough body.

[0019] Furthermore, a guide rod is slidingly provided inside the slide groove and is always located inside the guide groove. The guide rod located inside the lower slide groove is connected to the square block, and the remaining guide rods are connected to the pressure rollers at corresponding positions through telescopic blocks.

[0020] Furthermore, the external driving unit passes through the bracket and is connected to the support tray. The wire trough body moves to the laser cutting area under the guidance of several groups of conveyor rollers. Several matching grooves are opened along the circumferential direction on the side of the support plate away from the laser cutting head. The position of the annular table corresponding to the matching groove is provided with a linkage rod which is always located inside the matching groove.

[0021] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0022] The present invention is provided with a driving part. During the movement of the push block, the upper end surface of the push block pushes the mounting frame toward the inner side wall of the wire trough body, and the rotating roller is squeezed and finally enters the mounting groove. At this point, the side wall of the mounting frame is fitted with the inner side wall of the wire trough body. During the rotation operation of the annular table, the telescopic block can keep synchronous movement with the guide rod, thereby driving the pressure roller to perform continuous outward extension action. Through the coordinated action of the side wall of the mounting frame and the pressure roller, the wire trough body is synchronously clamped on both sides. This design effectively avoids the risk of plastic deformation of the side wall of the wire trough body due to excessive pressure on one side. At the same time, the synchronous and balanced clamping force on the inside and outside greatly improves the stability of the wire trough body before entering the cutting work, and ultimately lays the foundation for the subsequent laser cutting operation.

DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example:

[0037] See also Figure 1 - Figure 9 The present invention provides a technical solution: a galvanized metal trunking laser processing system using a segmented positioning structure, comprising:

[0038] A bracket 1 is provided with several mounting plates 11;

[0039] Trunk body 2;

[0040] The limiting mechanism 3 is provided in multiple numbers and is used to realize the position limiting work of the wire trough body 2;

[0041] The mounting plate 11 is provided with an annular platform 12 with a receiving groove 121 on its inner wall on the rear side wall. The bracket 1 is also provided with a receiving tray 13 connected to the mounting plate 11. The outer wall of the receiving tray 13 is provided with a laser cutting head 14 for cutting the wire trough body 2.

[0042] Among them, a plurality of guide grooves 122 are opened on both side walls of the accommodating groove 121 along the circumferential direction, and a support plate 15 with a slide groove 151 corresponding to the position of the guide groove 122 is provided inside the accommodating groove 121. A pressing roller 16 is provided on the support plate 15 to fit with the wire trough body 2. The setting of the pressing roller 16 not only realizes the guiding function of the wire trough body 2 during the movement, but also realizes the tightening and limiting work when the wire trough body 2 is cut by the laser cutting head 14;

[0043] The limiting mechanism 3 includes a mounting frame 31 which is arranged below the trunking body 2 and fits in with the side wall of the trunking body 2 .

[0044] The side wall of the mounting frame 31 is provided with an avoidance groove 311 and the mounting frame 31 is connected to the support plate 15 through a telescopic plate. Two driving members 32 symmetrical along the front-to-back direction are provided inside the mounting frame 31, and a tightening member 33 is provided on the end of the mounting frame 31 away from the driving member 32.

[0045] A sliding block 312 connected to the mounting frame 31 via a compression spring is slidably provided inside the avoidance groove 311 , and a guide roller 313 whose outer wall is in contact with the wire trough body 2 is provided on the side wall of the sliding block 312 via a telescopic member.

[0046] The two driving members 32 each include a gear 321 rotatably disposed inside the mounting frame 31 , with racks 322 sliding through the mounting frame 31 meshed on either side of the two gears 321 , and the side walls of the two racks 322 , which are positioned far apart, being commonly connected to a linkage frame 323 .

[0047] A push block 324 is provided at the bottom end of the mounting frame 31 , and a plurality of push plates 325 are provided on the upper end surface of the push block 324 . The plurality of push plates 325 are slidably set inside the linkage frame 323 , and the lower end surface of the push block 324 is slidably set inside the slide groove 151 through a square block 326 .

[0048] The abutting member 33 includes two abutting frames 331 symmetrically arranged in an upper and lower manner and connected to corresponding racks 322 respectively. The abutting frames 331 are slidably arranged inside the mounting frame 31. In the initial state, the upper and lower abutting frames 331 do not contact the wire trough body 2.

[0049] A guide rod 152 is slidingly provided inside the slide groove 151 and is always located inside the guide groove. The guide rod 152 located inside the lower slide groove 151 is connected to the square block 326, and the remaining guide rods 152 are connected to the pressure rollers 16 at corresponding positions through the telescopic block 153.

[0050] The peripheral drive unit passes through the bracket 1 and is connected to the support tray 13. The wire trough body 2 moves to the laser cutting area under the guidance of several groups of conveyor rollers. The support plate 15 is provided with several matching grooves along the circumferential direction on the side away from the laser cutting head 14. The position of the annular table 12 corresponding to the matching groove is provided with a linkage rod which is always located inside the matching groove.

[0051] During specific operation, the multi-section guiding and supporting work of the trunking body 2:

[0052] When the line trough body 2 (the line trough body 2 is a U-shaped structure, its main body constitutes the U-shape, and side wings extend on both sides of the opening to enhance structural strength or for subsequent installation, and in the conveying stage, the U-shaped opening of the line trough body 2 faces downward) is guided by several groups of conveying rollers into the interior of the mounting plate 11, the front end of the line trough body 2 first reaches the guide area, and it first connects with the mounting frame 31 below (the mounting frame 31 is arranged below the line trough body 2 and is connected to the support plate 15 through an adjustable telescopic plate. This connection method allows the mounting frame 31 to be fine-tuned according to actual work to adapt to line troughs of different specifications. The mounting frame 31 is away from the side of the guide roller 313, and a plurality of mounting slots extending in the up and down directions are opened. In each mounting slot, a shaft rod is slidably installed. The circumferential outer wall of the rod is fixedly connected to a roller. In addition, the same side wall of the mounting frame 31 is also provided with several arc grooves distributed along the left and right directions) and the position of the wire trough body 2 is not absolutely accurate in the process of contacting the mounting frame 31 (specifically, due to factors such as inevitable friction, vibration or geometric deviation of the wire trough itself during transportation, the wire trough body 2 will produce a slight lateral or longitudinal offset. A guide plate is fixedly connected to the rear side wall of the mounting frame 31, and the end face of the guide plate is arranged in an inclined shape. When the slightly skewed wire trough body 2 contacts the guide plate, the inclined surface will generate a lateral component of force on it, forcibly correcting its direction of travel, and ensuring that the wire trough body 2 can gradually enter the final cutting area in a correct, preset posture).

[0053] As the conveying roller group continues to drive, the front end of the trough body 2 gradually passes the guide plate and enters the auxiliary and support area. In the initial state, that is, the trough body 2 has not yet moved to the cutting area, and the support plate 15 and its supporting tray 13 have not rotated, the pressure roller 16 only remains tangent to the outer wall of the trough body 2, and the guide roller 313 is set inside the avoidance groove 311 through the sliding block 312 and the compression spring, and is pushed by its outer wall when the trough body 2 approaches. Similarly, the rotating roller is set inside the mounting groove of the mounting frame 31 through its shaft sliding. As the trough body 2 continues to move forward, its outer wall will gradually push the guide roller 313 and its sliding block 312, resulting in compression of the internal compression spring, so that the guide roller 313 is more closely fitted to the trough body 2. At the same time, the thrust of the trough body 2 will also cause the rotating roller to slide along the mounting groove in which it is located until the rotating roller is also closely fitted to the surface of the trough body 2.

[0054] By guiding and supporting the pressure roller 16, the guide roller 313 and the rotating roller in different directions, the stability of the wire trough body 2 during the transportation process is ensured to prevent it from being skewed due to the friction. At the same time, these freely rotating rollers (pressure roller 16, guide roller 313, rotating roller) not only provide support, but their rotational movement also assists the work of the main conveying roller group, effectively reducing the sliding friction of the wire trough body 2 during movement, thereby greatly improving the smoothness and efficiency of the transportation of the wire trough body 2.

[0055] The tightening and limiting work of the wire trough body 2 before laser cutting:

[0056] Before the wire trough body 2 is transported to the cutting station and prepared for laser cutting, the traditional process usually relies on clamps set on both sides and close to each other to synchronously limit the lateral displacement of the wire trough body 2. The original intention of this method is to prevent the wire trough body 2 from vibrating or offsetting due to external disturbances or its own thermal deformation during processing. However, this limiting method that relies solely on clamping on both sides has limitations. Specifically, laser cutting is essentially a high-energy thermal processing process. The clamps only exert a restraining force on both sides of the wire trough body 2. When the laser beam acts on the wire trough body 2, causing its local material to soften slightly, if the clamps on both sides exert excessive clamping force, it will have an adverse effect on the wire trough body 2 in a softened state. Uniform extrusion causes plastic deformation, affecting the final dimensional accuracy. In addition, the design of clamping on both sides fails to provide effective support for the corner area of ​​the wire trough body 2. Under the action of the laser cutting heat source, the material at the corner will produce large internal stress due to thermal expansion, which will cause the area to warp and deform, destroying the overall flatness of the wire trough. Based on this, the galvanized metal wire trough laser processing system with a segmented positioning structure is provided with a limiting mechanism 3, which can not only realize the tightening work of the wire trough body 2 from multiple directions, but also realize the support of the corners of the wire trough body 2 through the cooperation of the driving member 32 and the tightening member 33, thereby reducing the problem of warping and deformation at the corners of the wire trough body 2 during laser cutting.

[0057] Specifically, when the wire trough body 2 moves to the cutting operation area, its conveying work stops immediately. At this time, the external driving unit drives the support tray 13 and the annular table 12 to rotate synchronously (matching grooves are provided in the circumferential direction of the outer wall of the support disk 15, and the annular table 12 is provided with linkage rods corresponding to the positions of these matching grooves. In the stage when the annular table 12 starts the initial rotation, the linkage rod does not immediately drive the support disk 15 to rotate through the matching groove. During this period, the support tray 13 and the annular table 12 will first complete the initial synchronous rotation. Only when the linkage rod rotates to the other end of the matching groove will it synchronously drive the support disk 15 and the laser cutting head 14 installed thereon to enter the working rotation state). When the annular table 12 performs the rotation action, the several guide grooves opened inside it synchronously guide the guide rods 152 to slide smoothly in their respective slide grooves 151. During this process, the square block 326 connected to the guide rod 152 will drive the push block 324 along the preset track The guide roller 313 is connected to the sliding block 312 through the telescopic part, so that the mounting bracket 31 can effectively avoid being pulled and blocked when approaching the inner wall of the wire trough body 2, thereby ensuring the smoothness of the movement. During the approach process, the roller is squeezed and eventually enters the interior of the mounting groove. At this point, the side wall of the mounting bracket 31 is fitted with the inner wall of the wire trough body 2 (the side wall of the mounting bracket 31 is also provided with a number of arc grooves distributed along the left and right directions. The design of these arc grooves is to enhance the friction and contact strength between the outer wall of the mounting bracket 31 and the inner wall of the wire trough body 2, effectively preventing the lack of contact or slippage between the mounting bracket 31 and the inner wall of the wire trough body 2, and providing a more reliable physical basis for subsequent stable support and precise cutting).

[0058] During the rotation of the annular table 12, the telescopic block 153 can keep synchronous movement with the guide rod 152, thereby driving the pressure roller 16 to continuously extend (because the pressure roller 16 and the guide rod 152 are connected by the telescopic block 153, the pressure roller 16 will compress the telescopic block 153 during the extension process, and finally make the pressure roller 16 close to the outer wall of the wire groove body 2. It is worth noting that the outer wall of the pressure roller 16 is provided with a plurality of semicircular grooves along its circumferential direction. The core function of these semicircular grooves evenly distributed along the circumference is to increase the pressure roller 16 and the roughness of the contact area with the wire trough body 2, thereby significantly enhancing the friction coefficient between the two and ensuring the efficiency and stability of the pressing operation). Through the coordinated action of the side wall of the mounting frame 31 and the pressing roller 16, the wire trough body 2 is synchronously clamped on both sides. This design effectively avoids the risk of plastic deformation of the side wall of the wire trough body 2 due to excessive pressure applied on one side. At the same time, the synchronous and balanced clamping force on the inner and outer sides greatly improves the stability of the wire trough body 2 before entering the cutting work, and ultimately lays the foundation for the subsequent laser cutting operation.

[0059] Finally, under the continuous operation of the external driving unit, the linkage rod rotates to the other end of the matching groove, the support plate 15 and the laser cutting head 14 installed thereon enter the working rotation state, and the laser cutting head 14 realizes the cutting work of the wire groove body 2.

[0060] It should be pointed out that a gear 321 is rotatably provided inside the mounting frame 31, and two racks 322 are respectively meshed on both sides of the gear 321. The two racks 322 are designed to slide in the up and down directions and pass through the mounting frame 31. Structurally, the two racks 322 are commonly connected to a linkage frame 323 on opposite side walls. Specifically, the upper end faces of the racks 322 that are positioned far apart are commonly connected to an upper support frame 331, while the lower end faces of the racks 322 that are positioned close to each other are commonly connected to a lower support frame 331. Both of these support frames 331 can slide inside the mounting frame 31.

[0061] When the push block 324 moves following the corresponding guide rod 152, the push plate 325 set on its upper end surface will drive the linkage frame 323 to move upward synchronously (the push plate 325 is slidably set inside the linkage frame 323. This design ensures that when the push block 324 pushes the mounting frame 31 toward the inner wall of the wire trough body 2, the push plate 325 will not interfere, thereby ensuring the smoothness of movement). During the movement of the linkage frame 323, the two racks 322 will respectively engage with their corresponding gears 321. This meshing action enables the racks 322 on both sides of the gear 321 to move away synchronously. Correspondingly, the two support frames 331 arranged in the upper and lower directions will also expand outward synchronously following the racks 322 to which they are connected. Finally, this linkage mechanism realizes the support work of the inner corner area of ​​the wire trough body 2.

[0062] The multiple support frames 331 symmetrically arranged above and below can provide multi-point and balanced support forces for the inner corners of the wire trough body 2, which can effectively suppress the multi-directional warping deformation caused by local thermal expansion in the corner area when the wire trough body 2 is laser cut. At the same time, the multi-point support structure significantly enhances the stability of the support, and provides sufficient rigid constraints for the wire trough body 2 during the laser cutting process, thereby effectively reducing the displacement or deformation of the workpiece caused by processing thermal stress or mechanical vibration, and ensuring the cutting accuracy and processing quality.

[0063] It is worth emphasizing that the galvanized metal trunking laser processing system with segmented positioning structure has the following main advantages:

[0064] Advantage 1: During the movement of the push block 324, its upper end surface will push the mounting frame 31 toward the inner wall of the wire trough body 2, and the roller will be squeezed and eventually enter the mounting groove. At this point, the side wall of the mounting frame 31 is fitted with the inner wall of the wire trough body 2. During the rotation operation of the annular table 12, the telescopic block 153 can maintain synchronous movement with the guide rod 152, thereby driving the pressure roller 16 to perform a continuous outward extension action. Through the coordinated action of the side wall of the mounting frame 31 and the pressure roller 16, the wire trough body 2 is synchronously clamped on both sides. This design effectively avoids the risk of plastic deformation of the side wall of the wire trough body 2 due to excessive pressure on one side. At the same time, the synchronous and balanced clamping force on the inside and outside greatly improves the stability of the wire trough body 2 before entering the cutting work, and ultimately lays the foundation for the subsequent laser cutting operation.

[0065] Advantage 2: Due to factors such as inevitable friction, vibration or geometric deviation of the wire trough itself during the transportation process, the wire trough body 2 will produce a slight lateral or longitudinal offset. A guide plate is fixedly connected to the rear side wall of the mounting frame 31. The end face of the guide plate is set to be inclined. When the slightly tilted wire trough body 2 contacts the guide plate, the inclined surface will generate a lateral component force on it, forcibly correcting its direction of travel, ensuring that the wire trough body 2 can gradually enter the final cutting area in the correct, preset posture.

[0066] Advantage three, as the conveying roller group continues to drive, the front end of the trough body 2 gradually passes the guide plate and enters the auxiliary and support area, the pressure roller 16 only remains tangent to the outer wall of the trough body 2, and the guide roller 313 is pushed by its outer wall when approaching the trough body 2, so that the guide roller 313 fits more closely to the trough body 2. At the same time, the thrust of the trough body 2 will also cause the rotating roller to slide along the mounting groove in which it is located until the rotating roller also fits tightly to the surface of the trough body 2. Through the guidance and support of the pressure roller 16, the guide roller 313 and the rotating roller in different directions, the stability of the trough body 2 during the conveying process is ensured, and it is prevented from being skewed due to friction. At the same time, these freely rotatable rollers not only provide support, but their rotational movement also assists the work of the main conveying roller group, effectively reducing the sliding friction of the trough body 2 during movement, thereby greatly improving the smoothness and efficiency of the conveying of the trough body 2.

[0067] Advantage four, when the push block 324 moves with the corresponding guide rod 152, the push plate 325 set on its upper end surface will drive the linkage frame 323 to move upward synchronously. During the movement of the linkage frame 323, the two racks 322 will respectively engage with their corresponding gears 321. This meshing action enables the racks 322 on both sides of the gear 321 to move away synchronously. The multiple support frames 331 symmetrically arranged above and below can provide multi-point and balanced support forces for the inner corners of the wire trough body 2 under the drive of the corresponding racks 322. It can effectively suppress the multi-directional warping deformation of the corner area caused by local thermal expansion when the wire trough body 2 is laser cut.

[0068] Advantage five: The multi-point support structure of different rollers and multiple support frames 331 significantly enhances the stability of the support, providing sufficient rigid constraints for the wire trough body 2 during the laser cutting process, thereby effectively reducing the displacement or deformation of the workpiece caused by processing thermal stress or mechanical vibration, and ensuring cutting accuracy and processing quality.
