Description

Technical Field

[0001] This invention relates to the field of friction welding technology, specifically to a horizontal friction welding machine for welding bars with a fixed function. Background Technology

[0002] Friction welding involves applying a certain axial pressure to the welding end faces of two workpieces and causing the contact surfaces to undergo intense frictional motion. The heat generated by the friction heats the contact surfaces to a certain welding temperature, at which point the motion stops rapidly. A certain upsetting pressure is then applied, causing a certain amount of plastic deformation in the two workpiece metals, thereby firmly welding the two workpieces together.

[0003] However, existing friction welding is generally quite simple, only applying a certain axial pressure to the welding end faces of two cylindrical weldments. One weldment is fixed, and the other weldment generates heat through rotational friction for welding. There is no dust removal mechanism on the welding end faces of the two cylindrical weldments. This will cause dust particles to be trapped in the weld during the welding process, resulting in porosity or inclusions in the weld joint, affecting the welding quality. Porosity and inclusions will reduce the strength and reliability of the weld joint, and may even cause the weld joint to fail. Furthermore, dust particles will hinder the normal flow of molten metal, reduce the permeability of the weld joint, and reduce the strength of the weld joint, affecting its quality and reliability.

[0004] Furthermore, existing friction welding methods typically involve directly friction welding two cylindrical workpieces together when there are significant protrusions or unevenness on the welding end faces. However, the unevenness of the welding end faces leads to instability in the welding process. This instability results in uneven temperature distribution at the weld joint, affecting the welding quality and uniformity. Moreover, the unevenness of the welding end faces makes it easy for deformation to occur during the welding process. This deformation can cause the geometry of the weld joint to fail to meet requirements, thus affecting the dimensional accuracy and appearance quality of the weld joint.

[0005] Therefore, in view of this, the present invention proposes a horizontal friction welding machine for bar welding with a fixed function to make up for and improve the deficiencies of the prior art. Summary of the Invention

This can increase the contact area and heat transfer efficiency while improving the quality and strength of the welded joint.

[0022] (4) The grinding mechanism can increase the pressure on the axial direction of the grinding wheel under the drive of the rotating column II to fully grind the weld joint, thereby reducing the shape change of the weld joint during the welding process, reducing the risk of uneven contact and deformation during the welding process, and maintaining the size and shape accuracy of the joint.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Embodiments of the present invention

[0038] Please refer to Figures 1 to 6 As shown, a horizontal friction welding machine for welding bar stock with a fixed function includes a suspension arm 1, a mechanism housing 2 rotatably connected to the bottom of the suspension arm 1, and a drive group 3 disposed inside the mechanism housing 2. The horizontal friction welding machine for welding bar stock with a fixed function includes a cleaning mechanism and a grinding mechanism, both of which are connected to the drive group 3, and the cleaning mechanism is disposed above the grinding mechanism.

[0039] The cleaning mechanism is used to clean dust from the friction and welding surfaces of the bar stock;

[0040] The grinding mechanism is used to grind the friction-welded surface of the bar stock to make it smooth;

[0041] The outer casing 2 of the mechanism is provided with a handle on the front, and the drive assembly 3 consists of two rotating wheels and a transmission bar;

[0042] The cleaning mechanism includes a fixed bracket 401, which is fixedly connected to the inner wall of the outer shell 2 of the mechanism. A rotating rod 402 is rotatably connected to the fixed bracket 401. A bevel gear 403 is fixedly connected to one end of the rotating rod 402 near the fixed bracket 401. A rotating rod 404 is meshed on the side of the bevel gear 403 away from the rotating rod 402. A cam 405 is fixedly connected to the middle of the rotating rod 404. A roller 406 abuts against the smooth surface of the cam 405.

[0043] A fixed bracket 407 is rotatably connected to the end of the rotating rod 404 away from the bevel gear 403. A spring 408 is fixedly connected to the end of the fixed bracket 407 away from the rotating rod 404. A sliding bracket 409 is fixedly connected to the end of the spring 408 away from the fixed bracket 407. A bevel gear 410 is rotatably connected to the side of the sliding bracket 409 close to the rotating rod 402. A rolling brush 411 is meshed on the side of the bevel gear 410 away from the bevel gear 403.

[0044] Fixed bracket 2 407 is fixed to the inner wall surface of the outer shell 2 of the mechanism. Fixed bracket 1 401 and fixed bracket 2 407 both have cylindrical rods on the side near the sliding bracket 409, and the sliding bracket 409 has matching holes. The cylindrical rods on the side of fixed bracket 1 401 and fixed bracket 2 407 near the sliding bracket 409 slide in the holes opened in the sliding bracket 409.

[0045] Rotating rod 404 is rotatably connected between fixed bracket 401 and fixed bracket 407. There are two springs 408. The hole of bevel gear 410 is slidably adapted to the end of rotating rod 402 away from bevel gear 403. Rolling brush 411 is rotatably connected to the end of sliding bracket 409 away from roller 406.

[0046] Among them, the rolling brush 411 is used to clean the dust on the welding end face.

[0047] The effects achieved by this embodiment are as follows: In the prior art, friction welding is generally quite simple, only applying a certain axial pressure to the welding end faces of two cylindrical weldments. One weldment is fixed, and the other weldment generates heat through rotational friction for welding. However, there is no dust removal mechanism on the welding end faces of the two cylindrical weldments. This will cause dust particles to be trapped in the weld during the welding process, resulting in porosity or inclusions in the weld joint, affecting the welding quality. Porosity and inclusions will reduce the strength and reliability of the weld joint, and may even cause the weld joint to fail. Compared with the prior art, by setting up a cleaning mechanism, before friction welding, the rolling brush 411 continuously rotates to clean the dust on the welding end face, thereby reducing the dust adhering to the joint surface and affecting the cleanliness and contact quality of the joint. Furthermore, cleaning the dust on the joint can ensure that the contact surface is clean during friction welding, thereby ensuring full contact between the contact surfaces and improving the welding quality and strength.

[0048] Further examples:

[0049] Please refer to Figures 7 to 9 As shown, the grinding mechanism includes a rotating column 501, which is fixedly connected to the lower part of the drive group 3. A spur gear 502 is meshed in the middle of the rotating column 501. A rotating column 503 is fixedly connected to the shaft of the spur gear 502. A support frame 504 is rotatably connected to the middle of the rotating column 503. A connecting rod 505 is rotatably connected to the top of the rotating column 503. A swing rod 506 is rotatably connected to the end of the connecting rod 505 away from the rotating column 503. A sliding block 507 is rotatably connected to the end of the swing rod 506 away from the support frame 504.

[0050] Rotary column 501 is sleeved at one end away from drive group 3 and rotary column 508 is fixedly connected to one end of rotary column 508 away from rotary column 501.

[0051] The hole at the shaft of the spur gear 502 is adapted to the middle of the rotating column 503. There are two connecting rods 505, which are distributed on the upper and lower sides of the rotating column 503. The end of the rotating column 508 away from the grinding wheel 509 is provided with a groove. The sliding block 507 is slidably connected in the groove at the end of the rotating column 508 away from the grinding wheel 509. The hole at the end of the rotating column 508 away from the grinding wheel 509 is slidably adapted to the rotating column 501.

[0052] Among them, grinding wheel 509 is used to grind the weld end face flat.

[0053] The effects achieved by this embodiment are as follows: In the prior art, when there are large protrusions and unevenness on the welding end face, friction welding generally involves directly friction welding two cylindrical weldments together. However, the unevenness of the welding end face leads to instability in the welding process. An unstable welding process results in uneven temperature distribution at the weld joint, thus affecting the welding quality and uniformity. Compared with the prior art, the grinding mechanism can continuously grind the welding end face under the continuous rotation of the grinding wheel 509 before friction welding, thereby removing protrusions and depressions on the joint and making the contact surface flatter. This increases the contact area and heat transfer efficiency while improving the quality and strength of the weld joint.

[0054] The complete usage steps and working principle of the above embodiments are as follows:

[0055] In the initial state:

[0056] Cleaning mechanism: Roller 406 abuts against the smooth surface of cam 405, and spring 408 is in a naturally extended state;

[0057] Grinding mechanism: Rotary column 2 508 is located at one end near drive group 3;

[0058] The following is the working process of the cleaning mechanism cleaning dust from the welded end face:

[0059] When in use, the handle on the outer shell 2 is manually pushed to align the rolling brush 411 with the welding end face. The cleaning mechanism inside the outer shell 2 starts to work. The rotating rod 402 rotates counterclockwise under the drive of the drive group 3. The rotating rod 402 causes the rolling brush 411 to rotate counterclockwise through the sliding bevel gear 410. Since the rotating rod 402 rotates counterclockwise continuously under the drive of the drive group 3, the rolling brush 411 rotates counterclockwise continuously.

[0060] Simultaneously, the rotating rod 402, through the fixedly connected bevel gear 403, causes the rotating rod 404 meshing with it to rotate counterclockwise, thereby causing the cam 405, which is fixedly connected to the rotating rod 404, to rotate synchronously. At this time, the roller 406 slides toward the convex surface of the cam 405, thereby causing the sliding bracket 409 rotatably connected to the roller 406 to move away from the cam 405. At the same time, the sliding bracket 409 drives the rotatably connected rolling brush 411 to move synchronously, and the spring 408 fixedly connected to the sliding bracket 409 is gradually stretched. When the cam 405 rotates 180 degrees counterclockwise under the drive of the rotating rod 404, the roller 406 slides to the top of the convex surface of the cam 405, and the sliding bracket 409 rotatably connected to the roller 406 moves to the farthest point away from the cam 405. At this time, the spring 408 is stretched to the maximum.

[0061] Furthermore, when the cam 405 continues to rotate counterclockwise under the drive of the rotating rod 404, the aforementioned components undergo a recovery motion. The recovery motion process is the reverse of the aforementioned motion process. The cam 405 rotates continuously under the drive of the rotating rod 404, thereby causing the rolling brush 411 to reciprocate. Through the cleaning mechanism, before friction welding, the rolling brush 411 continuously rotates to clean the dust on the welding end face, thereby reducing the dust adhering to the joint surface and affecting the cleanliness and contact quality of the joint. Cleaning the dust on the joint ensures that the contact surface is clean during friction welding, thus ensuring full contact and improving welding quality and strength. Furthermore, the rolling brush 411 can reciprocate under the drive of the sliding bracket 409 to clean the dust on the welding end face more thoroughly, thereby minimizing defects such as bubbles and holes caused by dust during the welding process. In addition, thorough cleaning of the dust on the joint can improve heat transfer efficiency, making the welding process smoother and more efficient.

[0062] Please refer to the above work process. Figures 1 to 6 .

[0063] The following is the working process of the grinding mechanism grinding the weld end face to make it smooth:

[0064] When in use, the handle on the outer shell 2 is manually pushed to align the grinding wheel 509 with the welding end face. The grinding mechanism inside the outer shell 2 starts to work. The rotating column 1 501 rotates counterclockwise under the drive of the drive group 3. The rotating column 1 501 rotates counterclockwise through the sliding connection of the rotating column 2 508, which causes the grinding wheel 509 fixedly connected to it to rotate counterclockwise. Since the rotating column 1 501 rotates counterclockwise continuously under the drive of the drive group 3, the grinding wheel 509 rotates counterclockwise continuously.

[0065] Simultaneously, the rotating column 501, through the meshing spur gear 502, causes the rotating column 503, which is fixedly connected to it, to rotate clockwise. At this time, the rotating column 503, through the rotatably connected connecting rod 505, causes the swing rod 506 to rotate clockwise under the constraint of the rotatably connected support frame 504. This causes the swing rod 506, through the rotatably connected sliding block 507, to move the rotating column 508 away from the rotating column 501. At the same time, the rotating column 508 drives the fixedly connected grinding wheel 509 to move synchronously. When the rotating column 503 rotates 180 degrees clockwise under the drive of the spur gear 502, the rotating column 503, through the rotatably connected connecting rod 505, causes the swing rod 506 to rotate clockwise to the maximum angle that can be reached under the constraint of the rotatably connected support frame 504. This causes the swing rod 506, through the rotatably connected sliding block 507, to move the rotating column 508 away from the rotating column 501 to the farthest point. At the same time, the rotating column 508 drives the fixedly connected grinding wheel 509 to move synchronously to the farthest point.

[0066] Furthermore, as the rotating column 503 continues to rotate clockwise under the drive of the spur gear 502, the aforementioned components undergo a recovery motion. This recovery motion is the reverse of the aforementioned motion process. The rotating column 503 continuously rotates under the drive of the spur gear 502, causing the grinding wheel 509 to reciprocate. Through the provided grinding mechanism, the welding end face can be continuously ground under the continuous rotation of the grinding wheel 509 before friction welding. This removes protrusions and depressions on the joint, making the contact surface flatter, increasing the contact area and heat transfer efficiency, while improving the quality and strength of the welded joint. Furthermore, the grinding wheel 509, driven by the rotating column 508, applies a certain axial pressure to fully grind the welded joint, thereby reducing shape changes during welding, lowering the risk of uneven contact and deformation during welding, and maintaining the dimensional and shape accuracy of the joint.

[0067] Please refer to the above work process. Figures 7 to 9 .

[0068] Summary: The cleaning mechanism allows the rolling brush 411 to rotate continuously before friction welding to clean the dust on the welding end face. Cleaning the dust on the joint ensures that the contact surface is clean during friction welding, thereby ensuring full contact and improving the welding quality and strength.

[0069] The cleaning mechanism enables the rolling brush 411 to reciprocate under the drive of the sliding bracket 409, which can more thoroughly clean the dust on the welding end face, thereby minimizing the generation of defects such as bubbles and holes caused by dust during the welding process.

[0070] The grinding mechanism can continuously grind the welding end face under the continuous rotation of the grinding wheel 509 before friction welding, thereby removing the protrusions and depressions on the joint, making the contact surface flatter, increasing the contact area and heat transfer efficiency, and improving the quality and strength of the welded joint.

[0071] The grinding mechanism enables the grinding wheel 509 to apply a certain pressure axially under the drive of the rotating column 508 to fully grind the welded joint, thereby reducing the shape change of the welded joint during the welding process, reducing the risk of uneven contact and deformation during the welding process, and maintaining the size and shape accuracy of the joint.
