[0002] A car exhaust system has a front exhaust pipe and a rear exhaust pipe. During assembly, the rear exhaust pipe needs to be welded to the front exhaust pipe.

[0003] Currently, the most common welding method is manual welding. This method is not only inefficient, but it is also well known to have an impact on the health of welders. Therefore, welding equipment is needed.

[0004] However, the most difficult part of welding is the compatibility of welding parts of different models and specifications, as well as front exhaust pipes and rear exhaust pipes of different specifications. The current method for this is to change tooling, but changing tooling is also time-consuming. Therefore, how to achieve faster compatibility welding of front exhaust pipes and rear exhaust pipes of different models and specifications is a technical issue that needs to be considered.

[0044] The first feeding mechanism 2 includes a first material trough 21, a first telescopic cylinder 22 is installed on the side of the first material trough 21, a first slider 23 is connected to the output end of the first telescopic cylinder 22, a first motor 24 is installed on the first slider 23, a first support bar 25 is connected to the output end of the first motor 24, and the first feeding mechanism 2 includes a first electric slide rail 26, a first material receiving block 27 is installed at the output end of the first electric slide rail 26;

[0045] The second feeding mechanism 3 includes a second material trough 31, a second telescopic cylinder 32 is installed on the side of the second material trough 31, a second slider 33 is connected to the output end of the second telescopic cylinder 32, a second motor 34 is installed on the second slider 33, a second support bar 35 is connected to the output end of the second motor 34, and the second feeding mechanism 3 includes a second electric slide rail 36, a second material receiving block 37 is installed at the output end of the second electric slide rail 36.

[0046] The top clamping mechanism 4 includes a third telescopic cylinder 41, a fourth telescopic cylinder 42, a fifth telescopic cylinder 43 and a sixth telescopic cylinder 44 mounted on the frame 1;

[0047] The output end of the third telescopic cylinder 41 is connected to the first mounting plate 45. The first mounting plate 45 is equipped with the seventh telescopic cylinder 46. The first mounting plate 45 is slidably equipped with a motor mounting block 47 connected to the output end of the seventh telescopic cylinder 46. The motor mounting block 47 is equipped with the third motor 48. The output end of the third motor 48 is equipped with a sleeve 49.

[0048] The output end of the fourth telescopic cylinder 42 is connected to the third material support block 410, and the output end of the fifth telescopic cylinder 43 is connected to the fourth material support block 411.

[0049] The output end of the sixth telescopic cylinder 44 is connected to the second mounting plate 412, the second mounting plate 412 is mounted with the eighth telescopic cylinder 413, and the output end of the eighth telescopic cylinder 413 is rotatably mounted with the center point 414.

[0050] The output end of the welding mechanism 5 is positioned between the third material support block 410 and the fourth material support block 411;

[0051] The feeding mechanism 6 includes a ninth telescopic cylinder 61 mounted on the frame 1, and a push plate 62 is connected to the output end of the ninth telescopic cylinder 61;

[0052] A welding and forming method for automotive exhaust pipe welding and forming processing machinery as described in claims 1-6, comprising the following steps:

[0053] S1. Material preparation: The distance between the two sections of material to be welded is measured, the inner and outer diameters are measured, the burrs at the ends are deburred, the overall coaxiality is measured, and the length is determined.

[0054] S2. Equipment debugging: Debug the start and stop positions of the automated equipment at each workstation;

[0055] S3. Feeding: Manually or automatically using a multi-axis robotic arm to place the raw materials into the corresponding first material trough 21 or second material trough 31;

[0056] S4. Start the equipment and unload the material: Unload the material at the output end of the push plate 62.

[0057] When using a welding and forming machine for automotive exhaust pipes, the raw materials are inspected to ensure the consistency of the raw materials for each part, thereby ensuring the normal progress of welding and the consistency of the finished product.

[0058] The operating positions of each component are adjusted, with the most important position being the relative position of the third material support block 410 and the fourth material support block 411, to ensure that after feeding, the front exhaust pipe and the rear exhaust pipe are on the same axis after being clamped.

[0059] Example 1: Semi-automatic welding;

[0060] Manually place the front exhaust pipe on the third support block 410 and the rear exhaust pipe on the fourth support block 411. Then run the program. During operation, under the control of the program, the seventh telescopic cylinder 46 and the eighth telescopic cylinder 413 operate synchronously, driving the sleeve 49 and the center 414 to move, thereby pushing the front exhaust pipe and the rear exhaust pipe together to achieve the docking of the front exhaust pipe and the rear exhaust pipe. The program controls the welding mechanism 5 to perform welding. At the same time as welding begins, the third motor 48 runs, driving the sleeve 49 to rotate, thereby causing the front exhaust pipe and the rear exhaust pipe that are pushed together to rotate, achieving the purpose of welding one circle. After completion, the material can be manually unloaded.

[0061] Example 2: Fully automated welding;

[0062] A multi-axis robot or transfer device places the front exhaust pipe in the first material trough 21. The first motor 24 runs, driving the first support bar 25 to rotate, so that the first support bar 25 is located outside the first material trough 21. Then the first telescopic cylinder 22 runs, driving the first motor 24 and the first support bar 25 installed at the end of the first motor 24 to move backward to the tail of the front exhaust pipe. Then the first motor 24 runs, driving the first support bar 25 to rotate to the top of the first material trough 21. The first telescopic cylinder 22 runs, pushing the front exhaust pipe forward in the first material trough 21 until the front exhaust pipe moves onto the first support block 27. The first electric slide rail 26 runs, driving the first support block 27 and the front exhaust pipe placed on it to dock with the third support block 410. The fourth telescopic cylinder 42 runs, driving the third support block 410 to rise, lifting the front exhaust pipe to the debugging position. Thus, the automatic position movement and position determination of the front exhaust pipe are completed.

[0063] A multi-axis robot or transfer device places the front exhaust pipe in the second material trough 31. The second motor 34 operates, driving the second support bar 35 to rotate, so that the second support bar 35 is located outside the second material trough 31. Then, the second telescopic cylinder 32 operates, driving the second motor 34 and the second support bar 35 installed at the end of the second motor 34 to move backward to the tail of the rear exhaust pipe. Then, the second motor 34 operates, driving the second support bar 35 to rotate to the top of the second material trough 31. The second telescopic cylinder 32 operates, pushing the rear exhaust pipe forward in the second material trough 31 until the rear exhaust pipe moves onto the second support block 37. The second electric slide rail 36 operates, driving the second support block 37 and the rear exhaust pipe placed on it to move to dock with the fourth support block 411. The fifth telescopic cylinder 43 operates, driving the fourth support block 411 to rise, lifting the rear exhaust pipe to the debugging position. Thus, the automatic position movement and position determination of the rear exhaust pipe are completed.

[0064] After receiving the arrival information of the front and rear exhaust pipes, the program activates the third telescopic cylinder 41, causing the first mounting plate 45 to rise. This raises the seventh telescopic cylinder 46 and the third motor 48 until the axis of the sleeve 49 is aligned with the axis of the arrived front exhaust pipe. The sixth telescopic cylinder 44 then activates, causing the second mounting plate 415 to rise. This raises the eighth telescopic cylinder 413 until the axis of the tip 414 is aligned with the axis of the arrived rear exhaust pipe. The seventh and eighth telescopic cylinders 46 and 413 operate synchronously, moving the sleeve 49 and tip 414. The machine moves, thus bringing the front and rear exhaust pipes together to achieve the connection between them. The program controls the welding mechanism 5 to perform welding. At the same time as welding begins, the third motor 48 runs, driving the sleeve 49 to rotate, which in turn causes the front and rear exhaust pipes that are being pressed together to rotate, achieving the purpose of welding one revolution. After welding is completed, all components return to their positions, the position of the welded exhaust pipe drops, the ninth telescopic cylinder 61 runs, driving the push plate 62 to move forward, moving the exhaust pipe out of the welding area to make way for the welding of the next exhaust pipe, thus completing one welding process.

[0065] The preferred frame 1 is equipped with a baffle plate 7. This design limits the movement of the raw material on the electric slide rail, thus eliminating the need for proximity switches to limit the position. Moreover, the blocking method provides a better limiting effect. In practice, other methods of limiting the position can be considered depending on the specific circumstances, such as using proximity switches or photoelectric switches.

[0066] The preferred frame 1 is equipped with a transparent protective cover. This design protects the processing environment and production safety. In fact, protective measures can also be considered depending on the specific circumstances.

[0067] Preferably, the bottom of the third support block 410 and the fourth support block 411 are equipped with guide posts 8 that slide and match the frame 1. With this design, the lifting and lowering of the third support block 410 and the fourth support block 411 is more stable. In fact, a structure that makes the lifting and lowering of the third support block 410 and the fourth support block 411 more stable can also be considered according to specific circumstances.

[0068] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
