Abstract
Description
Technical Field
[0001] This application relates to the field of butt welding machine technology, specifically a combined safety protection device for butt welding machines. Background Technology
[0002] A welding machine is a device that uses resistance heat to weld workpieces together along their contact surfaces. It is widely used in metal processing, machinery manufacturing, construction, and other fields. Its working principle involves applying pressure to the workpiece using electrodes and passing an electric current through it, causing resistance heat to be generated at the workpiece contact surface. After the material is locally melted, a forging force is quickly applied to complete the welding. Butt welding machines are characterized by high welding efficiency, stable joint quality, and ease of operation. They can perform butt welding of workpieces of various shapes, such as bars, pipes, and plates. However, during butt welding operations, the intense light generated by the electric arc, spattering weld slag, and high-temperature sparks can easily cause injury to operators. Therefore, safety protection devices are an indispensable and important component of welding machines.
[0003] However, some existing protective devices for welding machines have fixed structures. When maintenance, repair, or workpiece replacement is required, these fixed devices restrict the operating space, causing inconvenience and reducing work efficiency. Furthermore, because the protective devices cannot be disassembled, they occupy additional space when the welding machine is not in use for extended periods, increasing storage costs and space requirements, and hindering ease of use.
[0004] Therefore, it is necessary to provide a combined safety protection device for welding machines to solve the above problems.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention
[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a combined safety protection device for welding machines, which solves the problems of fixed structure, inconvenient operation, and space occupation of traditional welding machine protection devices.
[0007] The technical solution adopted by this application to solve its technical problem is: a combined safety protection device for a butt welding machine, including a butt welding machine body and a protective component. The protective component is installed on the butt welding machine body. The protective component includes an arc-shaped protective cover and two support frames. An arc-shaped transparent plate is fixed on the arc-shaped protective cover. The two support frames are installed on both sides of the arc-shaped protective cover. A guide rail is fixed on one side of each of the two support frames. A U-shaped plate is fixed on both sides of the arc-shaped protective cover. A slider is fixed on one side of each of the two U-shaped plates. The slider is slidably connected to the guide rail and is suitable for adjusting the position of the arc-shaped protective cover. A locking mechanism for fixing the position of the arc-shaped protective cover is provided on the slider and the guide rail. An installation component for fixing the protective component on the butt welding machine body is provided on the two support frames.
[0008] Furthermore, the mounting assembly includes two clamping plates, which are mounted on the welding machine body. One side of each of the two support frames is slidably connected to an adjusting rod. The support frames and the adjusting rods are provided with limiting mechanisms for fixing the position of the adjusting rods. One side of each of the two adjusting rods is fixedly connected to the two clamping plates. A connecting assembly for connecting the two clamping plates is provided between the two clamping plates.
[0009] Furthermore, the connecting assembly includes connecting bolts, and through holes are provided at the upper ends of both clamping plates. The connecting bolts are installed in the through holes of the two clamping plates, and limit nuts are threaded to both sides of the connecting bolts, which is suitable for fixing the clamping plates to the welding machine body.
[0010] Furthermore, anti-slip pads are fixed to one side of both clamps.
[0011] Furthermore, the limiting mechanism includes a fastening bolt, and the support frame has a fastening threaded hole. After the fastening bolt is threadedly connected to the fastening threaded hole on the support frame, it fits tightly with the adjusting rod, which is suitable for limiting the adjusting rod.
[0012] Furthermore, the locking mechanism includes a locking bolt, a circular hole is provided on the U-shaped plate, and a locking threaded hole is provided on the slider. The locking bolt passes through the circular hole on the U-shaped plate and is threadedly connected to the locking threaded hole on the slider. One side of the locking bolt is tightly fitted with the guide rail, which is suitable for limiting the slider.
[0013] Furthermore, the material of the curved transparent plate is acrylic.
[0014] The beneficial effects of this application are as follows: The combined safety protection device for a butt welding machine provided by this application has an arc-shaped protective cover that is slidably connected to a guide rail via a slider. It can slide up and down along the guide rail, thereby flexibly adjusting the height of the protective cover to meet the needs of different welding operations. This allows the operator to easily adjust the position of the protective cover according to the size and position of the workpiece being welded, ensuring safety protection during the welding process. Through a locking mechanism, the protective cover can be fixed after its position is adjusted, preventing it from shifting due to vibration or external force during the welding process, thus ensuring the stability of the protective effect. The protective component is quickly fixed to the butt welding machine body through the installation component, making the installation and disassembly of the protective device simple and quick, without the need for complicated tools or steps. The design of the adjusting rod allows the protective component to adapt to butt welding machine bodies of different sizes. By sliding the adjusting rod and fixing it with fastening bolts, the protective component can be securely installed on the butt welding machine.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0026] like Figure 1-5 As shown, this application provides a combined safety protection device for a butt welding machine, including a butt welding machine body 1 and a protective component. The protective component is fixed to the lifting mechanism of the butt welding machine body 1 via a mounting component. The butt welding machine body 1 uses a cylinder to drive the clamp to move up and down to clamp the workpiece for welding. After clamping the workpiece, pressure is applied to the workpiece through electrodes and current is passed through it, causing resistance heat to be generated at the contact surface of the workpiece. After the material is locally melted, a forging force is quickly applied to complete the welding. The protective component is mounted on a mounting plate connected to the cylinder and can move up and down with the clamp.
[0027] Two support frames 4 are located on the left and right sides of the arc-shaped protective cover 2, respectively. Vertically arranged guide rails 5 are fixed to the inner sides of the two support frames 4. The cross-section of the guide rails 5 is dovetail-shaped to accommodate the sliding connection of the sliders 7. U-shaped plates 6 are fixed to the left and right sides of the arc-shaped protective cover 2, with the openings of the U-shaped plates 6 facing the arc-shaped protective cover 2. Slider 7 is welded to the inner side of the U-shaped plates 6. The sliders 7 slide with the guide rails 5, allowing the arc-shaped protective cover 2 to slide up and down along the guide rails 5.
[0028] The locking mechanism is used to fix the position of the arc-shaped protective cover 2 on the guide rail 5. The U-shaped plate 6 has a round hole that matches the locking bolt 14. The round hole passes through the plate body of the U-shaped plate 6. The slider 7 has a locking threaded hole that corresponds to the side of the guide rail 5.
[0029] When it is necessary to fix the arc-shaped protective cover 2, tighten the locking bolt 14 so that it passes through the round hole of the U-shaped plate 6 and is screwed into the locking thread hole of the slider 7. As the bolt is tightened, the end of the locking bolt 14 gradually presses against the side of the guide rail 5, and fixes the slider 7 on the guide rail 5 by friction, thereby locking the position of the arc-shaped protective cover 2.
[0030] When the position needs to be adjusted, loosen the locking bolt 14, and the arc-shaped protective cover 2 can be slid up and down. After adjustment, tighten the bolt again to fix it.
[0031] The mounting assembly is used to fix the protective assembly as a whole onto the welding machine body 1. Its structure includes a clamping plate 10, an adjusting rod 8, a fastening bolt 9, a connecting bolt 11, and an anti-slip pad 13.
[0032] A sliding groove is provided on the inner side of the upper end of the support frame 4. The adjusting rod 8 is inserted into the sliding groove and can slide left and right. The length of the sliding groove determines the adjustment range of the adjusting rod 8.
[0033] The limiting mechanism includes a fastening bolt 9. The side of the support frame 4 is provided with a fastening threaded hole that communicates with the slide groove. When the adjusting rod 8 slides to the appropriate position, the fastening bolt 9 is tightened so that its end presses against the side of the adjusting rod 8, thereby fixing the position of the adjusting rod 8.
[0034] The ends of the two adjusting rods 8 are fixedly connected to the clamping plates 10 respectively. The two clamping plates 10 are connected and fixed together by a connecting assembly. The connecting bolts 11 pass through the through holes at the upper ends of the two clamping plates 10, and the limiting nuts 12 are screwed into both sides respectively. By tightening the nuts 12, the clamping plates 10 are clamped to the position installed on the welding machine body 1, so as to realize the quick installation and removal of the protective components.
[0035] An anti-slip pad 13 made of rubber is pasted on the inner side of the clamping plate 10 that contacts the welding machine body 1 to increase friction and prevent the protective components from loosening.
[0036] The curved transparent plate 3 is fixed to the front opening of the curved protective cover 2 through a slot. It is made of acrylic, which makes it easy for operators to observe the welding process. It can block welding slag spatter and strong arc light, and can withstand the high temperature environment during welding. The curved transparent plate 3 has the same curvature as the curved protective cover 2, which expands the protection range and avoids stress concentration caused by right angle structure.
[0037] Working principle: The two clamping plates 10 are clamped onto the lifting mechanism mounting plate of the butt welding machine body 1 by connecting bolts 11 and limiting nuts 12. Anti-slip pads 13 increase friction to prevent loosening. The adjusting rod 8 can slide left and right in the slide groove of the support frame 4 and is tightened and fixed by fastening bolts 9. It can adapt to butt welding machine bodies of different sizes and realize the quick installation and removal of protective components.
[0038] The arc-shaped protective cover 2 is slidably connected to the guide rail 5 of the support frame 4 via the slider 7 on the U-shaped plate 6. When the protective height needs to be adjusted, the locking bolt 14 is loosened, and the arc-shaped protective cover 2 can slide up and down along the guide rail 5. After adjustment, the locking bolt 14 is tightened so that its end presses against the side of the guide rail 5, and the position of the slider 7 is fixed by friction, so as to achieve flexible adjustment of the protective range.
[0039] The curved transparent plate 3 is made of acrylic material, and its curved structure matches the curvature of the curved protective cover 2. It can effectively block welding slag spatter, strong arc light, and high-temperature sparks generated during welding, protecting the operator's safety. At the same time, its transparency allows for real-time observation of the welding process, avoiding operational errors caused by obstructed vision.
[0040] The protective component is installed on the lifting mechanism of the welding machine body and can move up and down synchronously with the fixture. When the fixture holds the workpiece for welding, the protective component always stays above the welding area, dynamically covering the danger zone and ensuring protection throughout the process.
[0041] When the welding machine needs maintenance, repair or workpiece replacement, the protective components can be quickly disassembled by loosening the limiting nut 12 of the connecting bolt 11, freeing up operating space and improving maintenance efficiency.
[0042] The modular structure allows for the separate storage of protective components and the welding machine body, avoiding the long-term space occupation of traditional fixed protective devices and reducing equipment storage costs and site burden.
[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
