Description

Technical Field

[0001] The invention relates to the technical field of friction welding, in particular to a copper brand friction welding device. Background Art

[0002] Friction welding is a method of connecting using friction heat. It is a type of solid-state welding technology, and friction stir welding is an advanced solid-state connection technology that uses the principles of friction heat and mechanical stirring to achieve connection between materials. The core of FSW is the use of a non-consumable cylindrical tool, the stirring needle. During the welding process, the stirring needle moves on a predetermined path while rotating at high speed, causing it to generate enough heat in the contact area with the material, so that the material softens but does not melt. Then, due to the shape and rotation of the stirring needle, the material is pushed and rearranged to form a strong joint under pressure. The whole process is carried out continuously until the entire welding length is completed. During the welding process of the workpiece by the existing friction welding equipment, when the friction welding gun head starts to rotate and stops, a small hole or pit will be left at the current position, so that there will be a pit on the workpiece after welding. It needs to be corrected by grinding, repair welding or other repair techniques, which increases the production process of the workpiece and affects the production efficiency. At the same time, during the welding process, it is necessary to ensure that the position of the workpiece is fixed. The existing equipment usually uses cylinder air pressure to fix the workpiece, but the clamping force provided by the air pressure is small, and the piston inside the cylinder is prone to retreat, resulting in a decrease in the clamping force. During the friction welding process, the workpiece is prone to position displacement, affecting the welding effect. Summary of the invention

[0033] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] See also Figure 1-10 In this embodiment, a copper-brand friction welding equipment is provided, including: a FSW machine tool 1, a workbench 101 is installed on one side of the FSW machine tool 1, a mounting plate 102 is installed on the top of the workbench 101, two slides 3 are arranged on the top of the mounting plate 102, and a first workpiece 8 and a second workpiece 9 are arranged on the top of the mounting plate 102; an oblique pressing component arranged on the top of the mounting plate 102, for fixing the first workpiece 8 and the second workpiece 9, the oblique pressing component includes: an equipment box 4, a hydraulic rod 401, a pushing block 402, a welding fixture 5, an inclined top block 502 and a pressing plate 505; and a protective component arranged on the slide 3 to avoid pits after welding, the protective component includes: an arc starting block 301, an arc closing block 303 and a positioning pin 304.

[0035] Among them, by setting up the protection component, the starting point and end point of the friction welding gun are not on the workpiece, avoiding leaving pits on the workpiece, and there is no need for subsequent grinding, repair welding or other repair techniques to correct the workpiece; secondly, by setting up the oblique pressure component, the first workpiece 8 and the second workpiece 9 can be pressed and fixed evenly and effectively, avoiding positional displacement of the first workpiece 8 and the second workpiece 9 during friction stir welding.

[0037] When friction welding is performed on the workpieces, the puncture of the first workpiece 8 and the second workpiece 9 to be welded is replaced, and the slide 3 is driven to move to a suitable position by the servo positioning mechanism 2, and then the arc-starting block 301 is placed on the slide 3, and the positioning pin 304 on the slide 3 is passed through the opening 302 on the arc-starting block 301, so that the arc-starting block 301 is placed on the slide 3, and because the cross-section of the opening 302 and the positioning pin 304 is arranged in a square shape, the positioning pin 304 can limit the arc-starting block 301, so as to avoid the position displacement of the arc-starting block 301 after it is placed;

[0038] Among them, two table support rollers 103 are installed on the top of the workbench 101, two support frames 601 are arranged on one side of the workbench 101, ground support rollers 6 are installed on the top of the support frames 601, and a movable control switch 7 is arranged on one side of the workbench 101.

[0039] After the arc starting block 301 is placed, the first workpiece 8 and the second workpiece 9 are placed on the slide 3, and the first workpiece 8 and the second workpiece 9 are placed vertically, and the end of the second workpiece 9 is close to the side of the first workpiece 8. At this time, the first workpiece 8 and the second workpiece 9 are both located under the welding fixture 5, and through the setting of the table support roller 103, the first workpiece 8 can be supported, and through the setting of the ground support roller 6, the second workpiece 9 can be supported.

[0040] Among them, four hydraulic rods 401 are installed inside the equipment box 4, and the four hydraulic rods 401 are arranged opposite to each other in pairs. A push block 402 is fixedly connected to one side of the hydraulic rod 401. Two welding fixtures 5 are installed on both sides of the equipment box 4. A moving groove 501 is opened inside the welding fixture 5. An inclined top block 502 is slidably connected inside the moving groove 501. A hydraulic pipe 4011 is connected to one side of the hydraulic rod 401. A space for the friction welding gun to move is left between the two welding fixtures 5 on the same side.

[0041] Among them, an inclined surface is provided at one end of the pushing block 402, the moving groove 501 is communicated with the equipment box 4, one end of the pushing block 402 extends into the moving groove 501 and is provided with an inclined surface, and an inclined top block 502 is provided with an inclined surface at one end close to the pushing block 402, and the inclined top block 502 and the pushing block 402 are tightly attached to each other, and a plurality of pressing grooves 503 are provided at the bottom of the welding fixture 5, and the cross-section of the pressing groove 503 is an inverted L-shaped structure, and the plurality of pressing grooves 503 are evenly arranged and distributed.

[0042] Furthermore, a pressing block 504 is slidably connected inside the pressing groove 503, and the bottom end of the pressing block 504 protrudes from the lower surface of the welding fixture 5 and is connected to the pressing plate 505. A pressing spring 506 is connected between the pressing block 504 and the pressing groove 503. An inclined surface is provided at the top of the pressing block 504, and a plurality of inclined grooves are provided at the bottom of the inclined top block 502, and the plurality of inclined grooves correspond to the positions of the plurality of pressing blocks 504.

[0043] Then, the hydraulic oil is transported to the inside of the hydraulic rod 401 through the hydraulic pipe 4011, so that the hydraulic rod 401 drives the pushing block 402 to move, so that the pushing block 402 moves in the direction of the inclined top block 502, and the inclined top block 502 is squeezed by the inclined surface at one end of the pushing block 402, so that the inclined top block 502 moves in the direction away from the equipment box 4. At this time, the inclined groove on the inclined top block 502 contacts the inclined surface at the top of the pressing block 504 and squeezes the pressing block 504, so that the multiple pressing blocks 504 are pressed by the movement of the inclined top block 502, so that the multiple pressing blocks 504 move downward synchronously, thereby driving the multiple pressing plates 505 to move in the direction of the slide 3, pressing and fixing the first workpiece 8 and the second workpiece 9, so as to avoid the position offset of the first workpiece 8 and the second workpiece 9 during the subsequent friction welding, thereby affecting the welding effect;

[0044] After the first workpiece 8 and the second workpiece 9 are pressed and fixed, the friction welding gun is moved to the top of the arc starting block 301 by the moving mechanism on the FSW machine tool 1, and the friction welding gun is located between the two welding fixtures 5, and then friction welding is started. Due to the sharp protrusion of the friction welding gun head, pits will appear at the arc starting position of the friction welding gun, which cannot be filled. At this time, through the setting of the arc starting block 301, the arc starting position of the friction welding gun can be transitioned to the arc starting block 301, so that the pits generated by arc starting remain on the arc starting block 301 instead of leaving the pits on the workpiece, and there is no need to make technical corrections to the pits generated by friction welding on the workpiece, thereby reducing the number of steps. Similarly, after the friction welding gun passes through the connection between the first workpiece 8 and the second workpiece 9, it finally stops on the arc closing block 303. Through the setting of the arc closing block 303, the pits generated by the friction welding gun after the end are also prevented from being transferred from the workpiece to the arc closing block 303.

[0045] Then, during the downward movement of the pressing block 504, the pressing spring 506 is squeezed and accumulates elastic force. After the welding is completed, the hydraulic rod 401 drives the pushing block 402 to retreat. At this time, the pressing block 504 drives the pressing plate 505 to move upward under the action of the elastic force of the pressing spring 506, and brings the inclined top block 502 back to its original position through the inclined groove.

[0046] Working principle:

[0047] When friction welding is performed on the workpieces, the puncture of the first workpiece 8 and the second workpiece 9 to be welded is replaced, and the slide 3 is driven to move to a suitable position by the servo positioning mechanism 2, and then the arc-starting block 301 is placed on the slide 3, and the positioning pin 304 on the slide 3 is passed through the opening 302 on the arc-starting block 301, so that the arc-starting block 301 is placed on the slide 3, and because the cross-section of the opening 302 and the positioning pin 304 is arranged in a square shape, the positioning pin 304 can limit the arc-starting block 301, so as to avoid the position displacement of the arc-starting block 301 after it is placed;

[0048] After the arc starting block 301 is placed, the first workpiece 8 and the second workpiece 9 are placed on the slide 3, and the first workpiece 8 and the second workpiece 9 are placed vertically, and the end of the second workpiece 9 is close to the side of the first workpiece 8. At this time, the first workpiece 8 and the second workpiece 9 are both located under the welding fixture 5, and through the setting of the table support roller 103, the first workpiece 8 can be supported, and through the setting of the ground support roller 6, the second workpiece 9 can be supported.

[0049] Then, the hydraulic oil is transported to the inside of the hydraulic rod 401 through the hydraulic pipe 4011, so that the hydraulic rod 401 drives the pushing block 402 to move, so that the pushing block 402 moves in the direction of the inclined top block 502, and the inclined top block 502 is squeezed by the inclined surface at one end of the pushing block 402, so that the inclined top block 502 moves in the direction away from the equipment box 4. At this time, the inclined groove on the inclined top block 502 contacts the inclined surface at the top of the pressing block 504 and squeezes the pressing block 504, so that the multiple pressing blocks 504 are pressed by the movement of the inclined top block 502, so that the multiple pressing blocks 504 move downward synchronously, thereby driving the multiple pressing plates 505 to move in the direction of the slide 3, pressing and fixing the first workpiece 8 and the second workpiece 9, so as to avoid the position offset of the first workpiece 8 and the second workpiece 9 during the subsequent friction welding, thereby affecting the welding effect;

[0050] After the first workpiece 8 and the second workpiece 9 are pressed and fixed, the friction welding gun is moved to the top of the arc starting block 301 by the moving mechanism on the FSW machine tool 1, and the friction welding gun is located between the two welding fixtures 5, and then friction welding is started. Due to the sharp protrusion of the friction welding gun head, pits will appear at the arc starting position of the friction welding gun, which cannot be filled. At this time, through the setting of the arc starting block 301, the arc starting position of the friction welding gun can be transitioned to the arc starting block 301, so that the pits generated by arc starting remain on the arc starting block 301 instead of leaving the pits on the workpiece, and there is no need to make technical corrections to the pits generated by friction welding on the workpiece, thereby reducing the number of steps. Similarly, after the friction welding gun passes through the connection between the first workpiece 8 and the second workpiece 9, it finally stops on the arc closing block 303. Through the setting of the arc closing block 303, the pits generated by the friction welding gun after the end are also prevented from being transferred from the workpiece to the arc closing block 303.

[0051] Then, during the downward movement of the pressing block 504, the pressing spring 506 is squeezed and accumulates elastic force. After the welding is completed, the hydraulic rod 401 drives the pushing block 402 to retreat. At this time, the pressing block 504 drives the pressing plate 505 to move upward under the action of the elastic force of the pressing spring 506, and brings the inclined top block 502 back to its original position through the inclined groove.
