Description

Technical Field

[0001] This utility model relates to the field of welding and fixing technology, specifically a fixing device for welding steel structure materials. Background Technology

[0002] Steel structure materials mainly include steel, such as profiles (angle steel, channel steel, I-beams, H-beams, etc.), steel plates, and construction steel (rebar, round steel, wire rod, coiled rebar, etc.). With its high strength, light weight, good plasticity and toughness, steel has become an indispensable structural material in modern construction and is widely used in high-rise buildings, bridges, industrial plants and other fields. The components or parts are usually connected by welds, bolts or rivets. When welding two sections of steel structure materials, it is necessary to fix the two sections of steel structure so that the welding surfaces are aligned before welding.

[0003] Because steel structure materials vary in shape and size, the required angle for aligning two sections of steel structure material will also differ. Existing fixing devices cannot flexibly fix different steel structure materials or different alignment methods. Therefore, we propose a fixing device for welding steel structure materials. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for welding steel structure materials. By allowing the support to be placed at any angle on any position on the support surface, and the steel material to be placed between the pressure plate above the support and the support, it is convenient to align the welding surfaces of two sections of steel to be welded together in different ways at any tilt angle. Then, by energizing the electromagnet, the support and the steel material can be fixed at the same time for welding, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for welding steel structure materials, including a support platform and a support base. Multiple electromagnets are uniformly embedded and installed inside the support platform, and support feet are fixed at the four corners of the bottom of the support platform. The support base has multiple plates placed side by side on the surface of the support platform. A pressure plate is horizontally arranged above the support base. Connecting plates that can slide through into the support base are connected to the lower sides of the pressure plate. Iron plates are horizontally fixed at the bottom of the connecting plates on both sides. Multiple screws are vertically and equidistantly screwed through the surface of the pressure plate, and pressure blocks are fixed at the bottom ends of the screws.

[0006] By adopting the above technical solution, the steel is first placed between the pressure plate and the support, and the support is supported on the surface of the support platform. The positions of the two sections of steel are adjusted to align them with the shape of the finished product to be welded. After alignment, the electromagnet is activated to magnetically attract the iron plate and press down the steel and the support. At the same time, the position of the support is locked and the steel is fixed. Welding can then be carried out on the steel. When adjusting the height of the pressure block before locking, it can be used to adapt to steel of different sizes.

[0007] Optionally, a rubber pad is fixedly attached to the surface of the support, and the rubber pad is placed between the two connecting plates.

[0008] By adopting the above technical solution, the steel is pressed against the surface of the support by the rubber pad, thus avoiding wear on the support.

[0009] Optionally, a first rubber sheet is attached and fixed to the bottom surface of the support, and multiple first rubber sheets are evenly arranged.

[0010] By adopting the above technical solution, when the support is pressed against the support surface, the first rubber sheet provides a good anti-slip effect.

[0011] Optionally, a second rubber sheet is fixed to the bottom surface of the pressure block, and the second rubber sheet is fixed to the bottom of the pressure block by an adhesive method.

[0012] By adopting the above technical solution, the pressure block abuts against the steel surface through the second rubber sheet, which has a certain anti-slip effect.

[0013] Optionally, a rotating block is fixed to the top of the screw, and the rotating block is fixed to the top of the screw by welding.

[0014] By adopting the above technical solution, the rotating block can drive the screw to rotate, thereby adjusting the height of the pressure block.

[0015] Optionally, the support surface at the through-hole of the connecting plate has an opening, through which the connecting plate passes into the support.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0017] 1. The technical solution of this application sets up a support with an internal electromagnet, so that the support can be placed at any angle on the surface of the support. The steel can be placed between the pressure plate above the support and the support, which makes it easy to align the two sections of steel to be welded together at any tilt angle in different ways. Then, the electromagnet is energized to fix the support and the steel at the same time for welding.

[0018] 2. The technical solution of this application allows the vertical height of the pressure block to be adjusted when the screw rotates, and the length of the pressure plate is long enough so that the support and the pressure block at the bottom of the pressure plate can be used to fix steel of different sizes.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a fixing device for welding steel structure materials, including a support 1 and a support 2. Multiple electromagnets 12 are uniformly embedded and installed inside the support 1. Support legs 11 are fixed at the four corners of the bottom of the support 1. The four corner support legs 11 are at the same height to achieve horizontal support for the support 1. When the electromagnets 12 are energized, the surface of the support 1 will have magnetism.

[0026] A support 2 is also provided, with multiple supports 2 placed side by side on the surface of the support 1. A pressure plate 3 is horizontally arranged above the support 2. A connecting plate 211 is vertically fixed on both sides of the pressure plate 3. The connecting plate 211 is slidably inserted into the support 2. The surface of the support 2 at the point where the connecting plate 211 passes through is provided with a plate opening 22. The connecting plate 211 passes through the plate opening 22 and enters the support 2. Iron plates 21 are horizontally fixed at the bottom of the connecting plates 211 on both sides. In addition, multiple screws 4 are vertically and equidistantly threaded through the surface of the pressure plate 3. A pressure block 41 is fixed at the bottom end of the screw 4.

[0027] In use, steel section 5 can be inserted between support 2 and pressure plate 3, and placed below pressure block 41. Then, another section of steel section 5 is placed between support 2 and pressure plate 3 in the same manner. At this point, support 2 can be positioned anywhere on the surface of support 1 at any angle, allowing adjustment of the distribution (angle, etc.) of the two sections of steel section 5 to align the welding surfaces as needed. Then, electromagnet 12 is energized and becomes magnetic, magnetically attracting iron plate 21 downwards. Iron plate 21 lowers pressure plate 3, which is then pressed against the surface of steel section 5 by pressure block 41 at the bottom of screw 4. This force is transmitted to support 2, pressing it firmly against the surface of support 1. Locking the position of support 2 also locks steel section 5 onto the base (see...). Figure 4 After that, welding can be carried out. In order to avoid the support 2 affecting the magnetic attraction force on the iron plate 21, the support 2 should preferably be made of a material that cannot be magnetically attracted and will not prevent the propagation of the magnetic field, such as plastic steel.

[0028] Additionally, a rotating block 42 is fixed to the top of the screw 4. The rotating block 42 is fixed to the top of the screw 4 by welding. When locking steel 5 of different sizes, the length of the pressure plate 3 is long enough and the number of pressure blocks 41 is sufficient, so it can adapt to steel 5 of different widths. When the thickness of the steel 5 is different, the screw 4 can be driven by the rotating block 42 before magnetic locking to adjust the height of the pressure blocks 41. This ensures that when the pressure blocks 41 are pressed against the surface of the steel 5, the iron plate 21 is located inside the lower part of the support 2 and there is a gap between it and the lower part of the support 2. This prevents the iron plate 21 from contacting the bottom of the support 2 first when magnetically attracted, thus preventing the pressure blocks 41 from being pressed against the surface of the steel 5 and locking it. This method can be used for steel 5 of different sizes.

[0029] A rubber pad 23 is fixedly attached to the surface of the support 2. The rubber pad 23 is placed between the two connecting plates 211. The steel 5 is in contact with the surface of the support 2 through the rubber pad 23 to avoid wear on the support 2.

[0030] The bottom surface of the support 2 is also fitted with a first rubber sheet 24, and multiple first rubber sheets 24 are evenly arranged. The bottom surface of the pressure block 41 is fixed with a second rubber sheet 411. The second rubber sheet 411 is fixed to the bottom of the pressure block 41 by fitting, which can achieve the purpose of anti-slip between the support 2 and the support platform 1 and between the pressure block 41 and the steel 5 when magnetically locked.

[0031] In use, the support platform 1 is supported by the legs 11. When fixing the steel 5 to be welded, a suitable number of supports 2 are placed on the surface of the support platform 1. First, the pressure plate 3 is lifted, which causes the iron plate 21 in the support 2 to rise to a higher height. Then, the steel 5 is inserted between the support 2 and the pressure plate 3. After placing another section of steel 5 between the support 2 and the pressure plate 3 in the same way, the support 2 can be positioned at any position and angle on the surface of the support platform 1. Thus, the distribution position (angle, etc.) of the two sections of steel 5 can be adjusted so that the two sections of steel 5 are distributed in the required way so that the welding surfaces are aligned. Then, the electromagnet 12 is energized and becomes magnetic, which will magnetically attract the iron plate 21 downwards. The iron plate 21 drives the pressure plate 21 to rise. The plate 3 is lowered and pressed against the surface of the steel 5 by the pressure block 41 at the bottom of the screw 4, and the force is transmitted to the support 2 so that it is pressed against the surface of the support 1. While locking the position of the support 2, the steel 5 is also pressed and locked onto the base. Welding can then be carried out. When performing the above operation, if locking steel 5 of different thicknesses is required, the screw 4 can be driven by the rotating block 42 to adjust the height of the pressure block 41. This ensures that when the pressure block 41 is pressed against the surface of the steel 5, the iron plate 21 is located inside the lower part of the support 2 and there is a gap between it and the inside lower part of the support 2. This prevents the iron plate 21 from contacting the bottom of the support 2 first when magnetic attraction occurs, thus preventing the pressure block 41 from pressing against the surface of the steel 5 and locking it in place.
