Description

Technical Field

[0001] This utility model relates to the field of mechanical welding technology, specifically a friction welding device for stainless steel materials. Background Technology

[0002] Friction welding refers to a method that utilizes the frictional heat generated by the friction between materials such as stainless steel to melt the friction surfaces. After pressure is applied and the surfaces are cooled, they can be joined together. However, during the welding of stainless steel, it is necessary to ensure continuous extrusion and friction between the materials to guarantee the precision of the friction-welded stainless steel. Therefore, the stability of stainless steel during friction welding is crucial to ensuring the precision of the friction-welded materials.

[0003] However, when traditional friction welding equipment performs friction welding on materials such as stainless steel, the stainless steel material to be welded is usually clamped and fixed. Furthermore, the traditional clamping and fixing of stainless steel materials requires rotating multiple clamping points to clamp and fix the stainless steel material, which is an extremely cumbersome, time-consuming and labor-intensive operation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a friction welding device for stainless steel materials. This solution can more conveniently clamp and fix stainless steel and other materials at multiple points simultaneously, greatly improving the convenience of clamping and fixing stainless steel materials, reducing the workload of workers, and also has an emergency stop function for timely stopping.

[0005] To solve the above problems, this utility model provides the following technical solution: a friction welding device for stainless steel materials, including a main board, a movable frame slidably connected to the upper surface of the main board, a fixed frame fixedly connected to the upper surface of the main board, a fixed column fixedly connected to the outer surface of the movable frame, a rotary motor mounted on the outer surface of the fixed frame, two sets of clamping and rotating mechanisms respectively connected to the fixed column and the output end of the rotary motor on the upper part of the main board, and a moving component for pulling the movable frame to move laterally.

[0006] The two sets of clamping and rotating mechanisms include clamping discs fixed to the outer end of the fixed column and the output shaft of the rotary motor, respectively, and clamping components for clamping and fixing stainless steel materials at multiple points; the clamping and rotating mechanism also includes a synchronization component connected to the clamping component, which is used to control the clamping component to clamp and fix the stainless steel materials at multiple points.

[0007] Furthermore, the clamping assembly includes a fixing ring fixed to the outer surface of the clamping disk, and a plurality of lead screws rotatably connected to a pre-drilled hole in the inner wall of the fixing ring. The clamping assembly also includes a lead screw seat threaded to the outer surface of the lead screw, and a clamping block fixed to the outer end of the lead screw seat.

[0008] Furthermore, the synchronization component includes an annular groove formed on the outer surface of the clamping disk and a toothed ring sleeved on the outer surface of the clamping disk, wherein a slip ring is fixedly connected to the inner wall of the toothed ring and rotates in cooperation with the inner wall of the annular groove.

[0009] Furthermore, the synchronization component also includes a gear fixed to the outer end of the lead screw and meshing with a gear ring, the gear ring being used to drive the rotation of the lead screw through the gear.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, by setting a synchronization component, the gear inside the synchronization component further includes several handles fixed on the outer surface of the gear ring, and a positioning plate fixed at the center position of the outer surface of the clamping plate.

[0011] Furthermore, a protruding plate is fixedly connected to the inner top wall of the fixed frame, and an electric push rod is installed on the outer surface of the protruding plate. The output end of the electric push rod slides through the protruding plate and is fixedly connected to a brake disc.

[0012] Furthermore, the moving component includes a mounting plate fixed to the upper surface of the motherboard and a hydraulic cylinder mounted on the outer surface of the mounting plate, wherein the output end of the hydraulic cylinder is fixedly connected to a connecting block that is fixedly connected to the inner bottom wall of the moving frame.

[0013] Furthermore, the moving component also includes a slide bar fixed to the upper surface of the motherboard and slidably engaged with a pre-reserved groove on the outer surface of the moving frame, and a baffle fixed to the outer end of the slide bar for limiting and blocking the moving frame.

[0014] Compared with existing technologies, this friction welding equipment for stainless steel materials has the following advantages:

[0015] 1. This utility model, by setting up a clamping and rotating mechanism, and the cooperation between the clamping component and the synchronization component within the clamping and rotating mechanism, can easily clamp materials such as stainless steel at the center of the clamping plate. Through a multi-point approach, it can stably align two stainless steel materials, ensuring the accuracy of the subsequent friction welding process and avoiding large deviations in the accuracy of alignment between the two materials during high-speed rotating friction welding. At the same time, the operation of clamping and fixing the materials is extremely convenient, requiring only the rotation of the synchronization component.

[0016] 2. This utility model incorporates an electric push rod, the output end of which can push the brake disc to press against the rotating clamping disc, allowing the brake disc to stop the clamping disc from rotating immediately by the pushing force of the electric push rod. By incorporating a moving component, the non-rotating stainless steel material can come into contact with the high-speed rotating stainless steel material, and through friction, a large amount of high temperature is generated, allowing the two stainless steel materials to fuse together and achieve welding.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integrally formed structures. Those skilled in the art can understand the specific meaning of these terms in this patent based on the specific circumstances.

[0025] See Figure 1 - Figure 4 This embodiment proposes a friction welding device for stainless steel materials, including a main board 1, a movable frame 2 slidably connected to the upper surface of the main board 1, a fixed frame 3 fixedly connected to the upper surface of the main board 1, a fixed column 5 fixedly connected to the outer surface of the movable frame 2, a rotary motor 6 mounted on the outer surface of the fixed frame 3, two sets of clamping and rotating mechanisms 4 respectively connected to the fixed column 5 and the output end of the rotary motor 6 on the upper part of the main board 1, and a moving component for pulling the movable frame 2 to move laterally.

[0026] Specifically, the movable component is designed to facilitate pushing or pulling the movable frame 2 closer to the fixed frame 3, and to allow the stainless steel material clamped and fixed on the movable frame 2 by the clamping and rotating mechanism 4 to move laterally and come into contact with the stainless steel component on the other side, and to continuously compress it. This allows the other material to rotate at high speed while the material clamped and fixed on the movable frame 2 contacts and compresses the rotating material. A large amount of heat is generated during the friction process, which fuses the two workpieces together and completes the welding after cooling, thereby achieving friction welding.

[0027] The moving component includes a mounting plate 10 fixed to the upper surface of the main board 1, and a hydraulic cylinder 11 mounted on the outer surface of the mounting plate 10. The output end of the hydraulic cylinder 11 is fixedly connected to a connecting block 12 that is fixedly connected to the inner bottom wall of the moving frame 2.

[0028] By setting up a moving component, a non-rotating stainless steel material can come into contact with a high-speed rotating stainless steel material, and a large amount of high temperature is generated through friction, which allows the two stainless steel materials to fuse together to achieve welding.

[0029] As a supplement, the hydraulic cylinder 11 inside the moving component facilitates the pushing or pulling of the connecting block 12 to move it, so that the connecting block 12 drives the moving frame 2 to move closer to the fixed frame 3, thereby making contact between the stainless steel materials, and continuing to squeeze during contact to improve the efficiency of friction welding.

[0030] The moving assembly also includes a slide bar 13 fixed to the upper surface of the main board 1 and slidingly engaged with a groove reserved on the outer surface of the moving frame 2, and a baffle 14 fixed to the outer end of the slide bar 13 for limiting and blocking the moving frame 2.

[0031] By setting the moving component and the slider 13 inside the moving component, the moving frame 2 can be moved more stably and smoothly, so that the moving frame 2 can drive the non-rotating stainless steel material to rub against the high-speed rotating stainless steel material under the limiting action of the slider 13.

[0032] As a supplement, the inner baffle 14 of the moving component can be set to limit and block the moving frame 2, so as to prevent the moving frame 2 from falling off the motherboard 1 and being damaged.

[0033] The two sets of clamping and rotating mechanisms 4 include clamping disks 401 fixed to the outer end of the fixed column 5 and the output shaft of the rotary motor 6, respectively, and clamping components for multi-point clamping and fixing of stainless steel materials; the clamping and rotating mechanism 4 also includes a synchronization component connected to the clamping component, which is used to control the clamping component to clamp and fix the stainless steel material at multiple points.

[0034] refer to Figures 1 to 4The clamping component is designed to facilitate multi-point clamping and fixing of stainless steel materials. The synchronization component eliminates the need for frequent control of multiple clamping and fixing points, allowing the synchronization component to simultaneously drive the clamping component to clamp and fix the stainless steel material at multiple points. This not only improves the convenience of operation but also enhances the clamping and fixing stability of the workpiece.

[0035] In one embodiment, the clamping assembly includes a fixing ring 402 fixed to the outer surface of the clamping disk 401, and a plurality of lead screws 403 rotatably connected to a pre-drilled hole in the inner wall of the fixing ring 402. The clamping assembly also includes a lead seat 404 threadedly connected to the outer surface of the lead screws 403, and a clamping block 405 fixed to the outer end of the lead seat 404.

[0036] By setting up clamping components, it is possible to accurately clamp and fix stainless steel materials, ensuring that the center positions of the two stainless steel materials are accurate and kept coaxial, thereby facilitating precise friction welding between the two stainless steel materials.

[0037] As a supplement, when clamping and fixing stainless steel materials, the stainless steel materials are placed in the center of the clamping plate 401, and the rotation of several lead screws 403 in the clamping assembly is driven by the synchronous component. The lead screws 403 can drive the lead screw seat 404 to move, thereby enabling the lead screw seat 404 to push the clamping block 405 to clamp and fix the stainless steel materials at multiple points.

[0038] In one embodiment, the synchronization component includes an annular groove 406 formed on the outer surface of the clamping disk 401, and a toothed ring 407 sleeved on the outer surface of the clamping disk 401. The inner wall of the toothed ring 407 is fixedly connected to a slip ring 408 that rotatably engages with the inner wall of the annular groove 406.

[0039] As one implementation method, by setting a synchronization component, the gear ring 407 in the synchronization component can facilitate the rotation of several lead screws 403 through subsequent components, thereby facilitating the simultaneous movement of several lead screws 403 to achieve simultaneous clamping and fixing of stainless steel materials at multiple points, ensuring that the stainless steel materials are accurately located in the central area of ​​the clamping plate 401.

[0040] As a supplement, the slip ring 408 is provided so that the toothed ring 407 can be installed into the annular groove 406 in the clamping plate 401, thereby facilitating the rotation of the toothed ring 407 on the outer ring of the clamping plate 401, and thus enabling the rotation of the lead screw 403 to be controlled by subsequent components.

[0041] The synchronization assembly also includes a gear 409 fixed to the outer end of the lead screw 403 and meshing with the gear ring 407. The gear ring 407 drives the rotation of the lead screw 403 through the gear 409.

[0042] By setting a synchronization component, the gear 409 inside the synchronization component can easily mesh with the teeth at the edge of the gear ring 407 for transmission. This allows several gears 409 and the lead screw 403 to rotate simultaneously when the gear ring 407 rotates, so that the lead screw 403 can drive the lead seat 404 to move, and then the lead seat 404 can push the clamping block 405 to clamp and fix the stainless steel material.

[0043] As a supplement, the gears 409 can be configured to be mutually adapted according to the number of lead screws 403, so that the gear ring 407 can drive multiple gears 409 and lead screws 403 to rotate, so as to clamp and fix the stainless steel material at multiple points.

[0044] The synchronization assembly also includes several handles 4010 fixed to the outer surface of the toothed ring 407, and a positioning disc 4011 fixed at the center of the outer surface of the clamping disc 401.

[0045] By setting a synchronization component, the handle 4010 inside the synchronization component allows the operator to manually pull the handle 4010, so that the handle 4010 can drive the toothed ring 407 to rotate under the limiting action of the annular groove 406, thereby enabling the toothed ring 407 to drive the clamping component to clamp and fix the stainless steel material.

[0046] As a supplement, the positioning plate 4011 facilitates the positioning and clamping of stainless steel materials. It allows the stainless steel materials to be placed in the positioning plate 4011 beforehand, and then the stainless steel materials are clamped and fixed by the cooperation of the synchronization component and the clamping component.

[0047] A protruding plate 7 is fixedly connected to the inner top wall of the fixed frame 3, and an electric push rod 8 is installed on the outer surface of the protruding plate 7. The output end of the electric push rod 8 slides through the protruding plate 7 and is fixedly connected to a brake disc 9.

[0048] By setting an electric push rod 8, the output end of the electric push rod 8 can push the brake disc 9 to squeeze the rotating clamping disc 401, so that the brake disc 9 can stop the clamping disc 401 from rotating in an emergency by the pushing force of the electric push rod 8, thereby improving the safety and practicality of the overall device.

[0049] As a supplement, the side of the brake disc 9 that contacts the clamping disc 401 is provided with anti-slip texture, which can facilitate the increase of friction during the squeezing process of the clamping disc 401, so that the clamping disc 401 can stop rotating quickly.

[0050] As a supplement, the rotary motor 6, electric push rod 8, and hydraulic cylinder 11 in this utility model are all conventional devices known to those skilled in the art and available on the market. Models can be selected or customized according to actual needs. Their setting methods, installation methods, and electrical connection methods can be debugged and operated in accordance with the requirements of their instruction manuals by those skilled in the art, and will not be described in detail here.

[0051] Working principle: When performing friction welding on stainless steel materials, the two stainless steel materials to be welded are first positioned on the positioning plates 4011 of the two clamping plates 401. By manually rotating the gear ring 407, the gear ring 407 can drive several gears 409 to rotate through meshing. The gears 409 can drive the lead screw 403 to rotate at the clamping plate 401. The lead screw 403 can drive the lead screw 404 to move stably under the limiting action of the clamping plate 401 through the threaded engagement with the lead screw seat 404. This allows the lead screw seat 404 to clamp the stainless steel material at multiple points through the clamping block 405. Thus, only rotating the gear ring 407 is needed to complete the clamping and positioning of the stainless steel material, greatly improving the convenience of operation.

[0052] After the stainless steel material is clamped and positioned, the rotary motor 6 is started. The output shaft of the rotary motor 6 drives the clamping plate 401 on the same side to rotate, so that the clamping plate 401 can simultaneously drive the clamped and positioned stainless steel material to rotate at high speed. At this time, the hydraulic cylinder 11 is started. The output end of the hydraulic cylinder 11 pulls the connecting block 12 and the moving frame 2 closer to the fixed frame 3, so that the stainless steel material clamped and positioned by the clamping and rotating mechanism 4 on the moving frame 2 moves and the two stainless steel materials come into contact with each other. The friction generated by the high-speed rotation can generate a large amount of high temperature in the two stainless steel materials. At the same time, the moving frame 2 is pulled closer to the fixed frame 3, so that the two stainless steel materials can be fused together to achieve welding. After that, normal cooling is performed to complete the friction welding of the stainless steel material.

[0053] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
