Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, and particularly relates to a support structure for large-size profiles. Background Art

[0002] Due to the advantages of high structural strength, light weight, easy processing, good durability and stability, profiles are widely used in many fields such as building structures, bridges, machinery manufacturing, equipment brackets, etc. However, the general laser cutting machines for profiles on the market can only cut profiles with a maximum width of 200 mm and a height of 200 mm at most, and are unable to process large-size profiles. Therefore, not only the laser cutting structure needs to be modified, but also a support structure for large-size profiles needs to be specifically designed to ensure stable and reliable support for the profiles in a static state to ensure laser cutting accuracy.

[0003] It can be seen that the existing technology still needs to be improved. Summary of the Utility Model

[0004] In view of the deficiencies of the above-mentioned existing technology, the purpose of the utility model is to provide a support structure for large-size profiles, so as to ensure stable and reliable support for the profiles in a static state to ensure laser cutting accuracy.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A support structure for large-size profiles includes a support, a bottom plate arranged below the support and fixed on the ground, and multiple height-adjusting components for adjusting the distance between the support and the bottom plate. A plurality of support vertical plates are arranged along the length direction of the support, and the tops of the support vertical plates form horizontally arranged teeth, and all the support vertical plates jointly support the large-size profile.

[0007] As a further improvement of the above technical solution, the support includes a longitudinally extending H-shaped steel and an adjusting flat plate arranged at the bottom of the H-shaped steel.

[0008] As a further improvement of the above technical solution, slots for inserting the support vertical plates are jointly opened at the tops of the two side plates of the H-shaped steel, and clamping slots for clamping with the side plates of the H-shaped steel are opened on the support vertical plates.

[0009] As a further improvement of the above technical solution, each group of the height-adjusting components includes a screw rod vertically arranged and threadedly connected to the bottom plate, a first nut, a second nut and a third nut cooperating with the screw rod. A through hole for the screw rod to pass through is opened on the adjusting flat plate. The adjusting flat plate is located between the first nut and the second nut, and the first nut and the second nut jointly clamp the adjusting flat plate. The third nut is used to lock the screw rod on the bottom plate.

[0010] As a further improvement of the above technical solution, there are two adjusting plates, both of which extend horizontally. The two adjusting plates are respectively arranged on the bottom surfaces at the front and rear ends of the H-shaped steel. The position of the through hole is located outside the H-shaped steel. The number of the bottom plates is equal to that of the adjusting plates and they are arranged in one-to-one correspondence.

[0011] As a further improvement of the above technical solution, a grasping opening is formed through the middle of the supporting vertical plate.

Detailed Embodiment

[0018] The present utility model provides a large-size profile support structure. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0019] Please refer toFigure 1 - Figure 2 , the present utility model provides a support structure for large-sized profiles, which includes a support 1, a bottom plate 2 arranged below the support 1 and fixed on the ground, and multiple height-adjusting components 3 for adjusting the distance between the support 1 and the bottom plate 2. A plurality of support vertical plates 4 are arranged along the length direction of the support 1, and tooth-like projections 41 arranged horizontally are formed at the tops of the support vertical plates 4. All the support vertical plates 4 jointly support the large-sized profile. The tooth-like projection 41 structure can reduce the contact area with the profile, thereby reducing heat conduction and avoiding the formation of a large heat-affected zone at the bottom of the profile.

[0020] In fact, multiple support structures for large-sized profiles provided by the present utility model will be arranged at intervals longitudinally on the ground to cope with the cutting of large-sized profiles with a long length. The large-sized profile is placed on the support structure by means of hoisting, and then a spirit level is used to detect whether the large-sized profile is placed correctly. It can be understood that the multiple support vertical plates 4 arranged on the support 1 and the horizontally arranged tooth-like projections 41 formed at the tops of the support vertical plates 4 can provide a stable contact surface and strong load-bearing capacity. Coupled with the large self-weight of the large-sized profile (usually several hundred kilograms to several tons), it ensures the stability and reliability of the large-sized profile during static placement, reduces deformation or displacement caused by unstable support, and guarantees the accuracy of laser cutting. In addition, by arranging multiple height-adjusting components 3, the distance between the support 1 and the bottom plate 2 can be flexibly adjusted, so as to adapt to large-sized profiles with different heights and widths, improving the versatility and flexibility of the support structure.

[0021] Compared with the prior art, the support structure for large-sized profiles provided by the present utility model has a compact structure, solves the problem that the cutting platform of a traditional laser cutting machine cannot support large-sized profiles, expands the processing range, improves the production efficiency, and meets the market demand for the processing of large-sized profiles.

[0022] The support 1 includes an H-shaped steel 11 extending longitudinally and an adjusting flat plate 12 arranged at the bottom of the H-shaped steel 11. Due to the characteristics of its cross-sectional shape, the H-shaped steel 11 has high bending and torsional resistance properties, which can effectively enhance the rigidity and stability of the entire support structure. Especially when supporting large-sized profiles, it can bear greater loads without deformation. By adding the adjusting flat plate 12 at the bottom of the H-shaped steel 11 and combining with the height-adjusting component 3, the distance between the support 1 and the bottom plate 2 can be adjusted more precisely, realizing fine adjustment of the height of the large-sized profile, ensuring the precise positioning of the profile during laser cutting, and improving the cutting accuracy.

[0023] To enable the support structure to handle profiles of different sizes, the maximum size of the profile that the support structure can support is designed to be 1200 mm in width and 600 mm in height, and the minimum size of the profile that can be supported is 200 mm in width and 200 mm in height. During actual application, the staff changes and replaces the appropriate support vertical plate 4 according to the size of the profile to be cut. The difference between different types of support vertical plates 4 lies in the contact area at their tops. Therefore, the support vertical plate 4 and the H-shaped steel 11 should be designed as detachable structures. Specifically, see Figure 3 and Figure 4 As shown, above the middle plate of the H-shaped steel 11, a concave cavity for inserting the support vertical plate 4 is formed by the side plates. Slots 111 for inserting the support vertical plate 4 are commonly opened at the tops of the two side plates of the H-shaped steel 11. A clamping groove 42 for clamping with the side plate of the H-shaped steel 11 is provided on the support vertical plate 4. By inserting the support vertical plate 4 into the concave cavity and the slots 111 of the H-shaped steel 11 and using the clamping groove 42 to clamp with the side plate of the H-shaped steel 11, a firm mechanical connection is formed. This design greatly enhances the connection strength between the support vertical plate 4 and the H-shaped steel 11, and the support vertical plate 4 cannot move by itself. In addition, the design of the slots 111 and the clamping grooves 42 makes the installation and position adjustment of the support vertical plate 4 simple and fast. Precise alignment can be completed without additional tools, simplifying the assembly process. It is also convenient to replace the appropriate support vertical plate 4 subsequently. The number and position of the support vertical plates 4 can also be flexibly increased or decreased according to actual needs to adapt to profiles of different sizes and shapes, enhancing the versatility and flexibility of the support structure.

[0024] See Figure 1 As shown, each set of the height adjustment components 3 includes a screw rod 31 vertically arranged and threadedly connected to the bottom plate 2, a first nut 32, a second nut 33, and a third nut 34 that cooperate with the screw rod 31. A through hole 121 for the screw rod 31 to pass through is provided on the adjustment flat plate 12. The adjustment flat plate 12 is located between the first nut 32 and the second nut 33, and the first nut 32 and the second nut 33 jointly clamp the adjustment flat plate 12. The third nut 34 is used to lock the screw rod 31 on the bottom plate 2. The screw rod 31 is fixed on the bottom plate 2 by the third nut 34, avoiding the possible position deviation caused by rotating the screw rod 31, ensuring the stability of the distance adjustment between the adjustment flat plate 12 and the bottom plate 2, and thus improving the support accuracy of large-sized profiles during laser cutting. By screwing the first nut 32 and the second nut 33 to adjust the position of the adjustment flat plate 12, thereby the support height of the support vertical plate 4 can be adjusted. The adjustment operation is intuitive and simple. With the mutual cooperation of the first nut 32 and the second nut 33, the position of the adjustment flat plate 12 can be effectively locked. Even when large vibrations occur during the cutting of large-sized profiles, the adjustment flat plate 12 can still be kept stable, improving the safety and reliability of the entire support structure.

[0025] In this embodiment, the adjustment plates 12 are provided with two and both extend in the transverse direction. The two adjustment plates 12 are respectively arranged on the bottom surface of the front and rear ends of the H-shaped steel 11. The through hole 121 is located on the outside of the H-shaped steel 11 to facilitate the screwing of the first nut 32. The number of the bottom plate 2 and the adjustment plates 12 is equal and they are arranged one by one, so that each adjustment plate 12 can be adjusted independently. Compared with the structural setting of a whole adjustment plate 12, the two adjustment plates 12 are respectively located at the front and rear ends of the H-shaped steel 11. While saving materials, it can ensure the provision of balanced support force, effectively disperse the weight of the profile, reduce deformation caused by excessive local force, and improve the stability and balance of the entire support structure.

[0026] Preferably, a grab opening 43 is provided in the middle of the support vertical plate 4. By providing the grab opening 43, it is convenient to pass the sling through the grab opening 43 for lifting when replacing the tooth plate, or directly reach into the grab opening 43 by hand to lift the support vertical plate 4.

[0027] Preferably, the base plate 2 is provided with a mounting hole 21, and the expansion bolt passes through the mounting hole 21 to fix the base plate 2 to the ground. Even when subjected to the heavy pressure of large-sized profiles and vibrations during laser cutting, the base plate 2 can remain stable without displacement or loosening.
