Description

Technical Field

[0001] This utility model relates to the field of intersection line cutting technology, and in particular to the tooling for processing intersection lines of large-span steel structure components. Background Technology

[0002] Steel structure components mainly include steel columns, steel beams, truss members, etc. When connecting steel structures, especially in tubular truss structures, it is often necessary to cut the intersection line at the intersection of the components to ensure that the components can be accurately connected and that the force is reasonably transferred.

[0003] Existing methods for intersecting line cutting mainly involve using support members to support the middle of the steel component before direct cutting. However, when processing the end intersecting lines of large-span steel components, as the cutting progresses, the cut-off portion gradually loses its overall support and may sag under gravity, leading to local tearing of the cut or changes in the bevel shape, affecting the subsequent welding quality. Furthermore, the large amount of high-temperature slag and metal debris generated during the cutting process will splash and accumulate, which not only pollutes the working environment and is difficult to clean, but may also damage the equipment guide rails and pose certain safety hazards. Summary of the Invention

[0004] The purpose of this utility model is to provide a tooling for processing the intersection lines of large-span steel structure components in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a machining fixture for the intersection line of large-span steel structure components, including a base plate, a support mechanism at the middle of the top of the base plate for supporting the middle of the steel component, clamping mechanisms at both ends of the top of the base plate for clamping the two ends of the steel component, a supporting mechanism between the support mechanism and the clamping mechanism for supporting the overhanging end or cutting area of ​​the steel component, and a heat-resistant elastic cloth connected between the supporting mechanism and the clamping mechanism for collecting debris.

[0006] Preferably, the bottom of the heat-resistant elastic fabric is provided with a discharge pipe, and the lower end of the discharge pipe is threaded with a sealing cap.

[0008] Preferably, the support mechanism includes a support arm, a side plate, and a connecting rod. The support arm and the side plate are both arc-shaped and integrally formed. The support arm and the side plate form an inverted Ω shape. The connecting rod is installed at the bottom of the support arm.

[0009] Preferably, the clamping mechanism includes a base and a three-jaw chuck, and the upper end of the base is provided with a first driving mechanism for driving the three-jaw chuck to rotate.

[0010] Preferably, the support mechanism includes a mounting base, on which a transverse bidirectional threaded rod is rotatably mounted. Guide blocks are threaded to the opposite outer threads at both ends of the bidirectional threaded rod. An X-shaped support frame is mounted on the top of the guide blocks. A roller is rotatably connected to the upper end of the support frame. A second drive mechanism for driving the roller to rotate is provided on the outer side of the support frame.

[0011] Preferably, a rocker arm is mounted on the side of the bidirectional threaded rod extending from the mounting base, and a nut is threaded onto the outer side of the bidirectional threaded rod located between the mounting base and the rocker arm.

[0014] 2. In this application, a heat-resistant elastic cloth is provided to form a debris collection area below the cutting area, which concentrates and collects most of the high-temperature debris and slag, improving the working environment and reducing the difficulty of cleaning and safety risks.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 This utility model provides a technical solution: a tooling for processing the intersection line of large-span steel structure components, including a base plate 1, a support mechanism 2 provided at the middle of the top of the base plate 1 for supporting the middle of the steel component, clamping mechanisms 3 provided at both ends of the top of the base plate 1 for clamping the two ends of the steel component, a support mechanism 4 provided between the support mechanism 2 and the clamping mechanism 3 for supporting the overhanging end or cutting area of ​​the steel component, and a heat-resistant elastic cloth 5 connected between the support mechanism 4 and the clamping mechanism 3 for collecting debris.

[0019] Specifically, such as Figure 2 As shown, a discharge pipe 6 is provided at the bottom of the heat-resistant elastic cloth 5. A sealing cap 7 is threaded to the lower end of the discharge pipe 6. By opening the sealing cap 7, the debris collected in the heat-resistant elastic cloth 5 can be discharged from the discharge pipe 6.

[0020] Specifically, such as Figure 3As shown, the heat-resistant elastic cloth 5 has a multi-layer composite structure, including an aluminum foil layer 501, a ceramic fiber cotton layer 502, and a protective cloth layer 503 stacked from top to bottom. The aluminum foil layer 501 is used to reflect heat, the ceramic fiber cotton layer 502 is used for heat insulation, and the protective cloth layer 503 is used for wear resistance and to prevent fiber shedding. The edges of the aluminum foil layer 501, the ceramic fiber cotton layer 502, and the protective cloth layer 503 are sewn together with a flexible graphite tape 504 (which serves to resist high temperatures). The flexible graphite tape 504 is wrapped with an elastic tape 505, which allows the heat-resistant elastic cloth 5 to elastically adhere to the surface of the steel component and reduce the dispersion of debris.

[0021] Specifically, such as Figure 2 As shown, the support mechanism 4 includes a support arm 401, a side plate 402, and a connecting rod 403. The support arm 401 and the side plate 402 are both arc-shaped and integrally formed, forming an inverted Ω shape. The connecting rod 403 is installed at the bottom of the support arm 401. The arc-shaped side plate 402 provides tolerance space for the cut steel structure cantilever end, guides the cantilever end smoothly into the support position of the support arm 401, and provides stable support.

[0022] Specifically, such as Figure 2 As shown, the clamping mechanism 3 includes a base 301 and a three-jaw chuck 302. The upper end of the base 301 is provided with a first driving mechanism 303 for driving the three-jaw chuck 302 to rotate. The three-jaw chuck 302 is used to fix the end of the steel component that is about to be cut off. The first driving mechanism 303 is used to drive the three-jaw chuck 302 to rotate, and cooperate with external cutting equipment to complete the intersecting line processing.

[0023] Specifically, such as Figure 4 As shown, the support mechanism 2 includes a mounting base 201. A transverse bidirectional threaded rod 202 is rotatably mounted inside the mounting base 201. Guide blocks 203 are threaded to the opposite outer threads at both ends of the bidirectional threaded rod 202. X-shaped support frames 204 are mounted on the top of the guide blocks 203. The support frames 204 are divided into two groups in an X-shape and connected at the center by a pin, allowing the two groups of support frames 204 to adjust their height like scissors to accommodate steel components of different diameters. This ensures that the supporting mechanism 4 and the clamping mechanism 3 are in close contact with the support mechanism 2. To accommodate steel components of different heights, a lifting drive mechanism (such as a cylinder) is installed inside the connecting rod 403 and the base 301 to align the center of the steel components with different diameters. A roller 205 is rotatably connected to the upper end of the support frame 204. A second drive mechanism 2041 for driving the roller 205 to rotate is provided on the outside of the support frame 204. The first drive mechanism 303 and the second drive mechanism 2041 can be motors. The second drive mechanism 2041 serves as an auxiliary drive and is synchronized with the first drive mechanism 303 to ensure that the long steel components rotate smoothly.

[0024] Specifically, such as Figure 4As shown, a rocker arm 206 is installed on one side of the bidirectional threaded rod 202 extending out of the mounting base 201. A nut 207 is threadedly connected to the outer side of the bidirectional threaded rod 202 between the mounting base 201 and the rocker arm 206. The bidirectional threaded rod 202 is fixed by locking the bidirectional threaded rod 202 with the nut 207.

[0025] Specifically, such as Figure 5 As shown, sliders 8 are installed at the bottom of the support mechanism 2, clamping mechanism 3 and supporting mechanism 4. A slide rail 10 for sliding slider 8 is installed on the top of the base plate 1. A connecting plate 9 is installed on the outside of slider 8. A plug rod 11 is inserted into the connecting plate 9. Multiple insertion holes 101 that are adapted to the size of the plug rod 11 are opened on the top of the base plate 1. The support mechanism 2, clamping mechanism 3 and supporting mechanism 4 are fixed after the position is adjusted by the plug rod 11 and the insertion holes 101, which can adapt to steel components of different lengths.

[0026] In summary, the working principle of the machining fixture for the intersection line of large-span steel structure components provided in this embodiment is as follows: Before processing, the distance between the two clamping mechanisms 3 and the middle support mechanism 2 is adjusted by sliding the slider 8 according to the length of the steel component to be processed, and locked by the cooperation of the insertion rod 11 and the insertion hole 101. The support height of the support mechanism 2 is adjusted by the rocker arm 206. At the same time, the lifting drive mechanism inside the support mechanism 4 and the clamping mechanism 3 is activated to keep each mechanism at the same horizontal height as the center of the steel component. Then, the steel component is hoisted onto the roller 205 of the support mechanism 2 and the support arm 401 of the support mechanism 4, and its two ends are clamped by the three-jaw chuck 302. During processing, the first drive mechanism 303 is started, which drives the three-jaw chuck 302 to rotate the steel component at a uniform speed. The second drive mechanism 2041 can synchronously drive the roller 205 to assist in rotation, ensuring that the ultra-long component rotates smoothly. The external cutting equipment performs intersecting line cutting on the rotating steel component according to the preset program. During the cutting process, the overhanging end of the steel component enters the support arm 401 under the guidance of the side plate 402, effectively overcoming its sagging tendency caused by its own weight, thereby avoiding cut tearing, bevel deformation, and eliminating the risk of component falling. Throughout the cutting process, the high-temperature slag and debris generated are effectively collected by the heat-resistant elastic cloth 5 below, reducing debris scattering.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
