Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts processing, in particular to an automobile parts processing welding cooling device. Background Art

[0002] Automobile is one of the industries where welding is most widely used. Automobile welding mainly includes body welding, engine welding, chassis welding, exhaust pipe assembly welding, etc.

[0003] The exhaust pipe is a vital component of a vehicle's exhaust system. Its functions include exhaust gas discharge and treatment, noise and vibration reduction, and engine exhaust back pressure reduction. The design and manufacturing quality of the exhaust pipe directly impact engine efficiency, fuel economy, and powertrain smoothness. More than just an external component, the exhaust pipe is a key factor in the efficient and smooth operation of the engine.

[0004] Currently, when manufacturing exhaust pipes, the sheet metal needs to be made into different types of tubes first, and then the different tubes are processed into different shapes, such as inclined tubes or S-shaped tubes. The different types of tubes are then assembled and welded. When all the tubes are welded, a complete exhaust pipe system is formed.

[0005] When assembling and welding exhaust pipes, the most commonly used welding method is argon arc welding. Argon arc welding is a welding technique that uses inert gas argon as a shielding gas. High current is used to melt the welding material on the substrate being welded, thus achieving a connection. The role of argon is to prevent the welding material from being oxidized. It is suitable for the case of thin exhaust pipe walls because it can provide better protection and prevent the weld from being oxidized.

[0006] However, during the welding process, shielding gas will be ejected from the welding nozzle on the welding gun and act on the welding position. The ejected shielding gas will diffuse into the external environment, resulting in a decrease in the protective effect of the shielding gas on the welding position. Therefore, it is necessary to increase the amount of shielding gas ejected to achieve protection of the welding position, which will increase the cost of welding. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art and solve the above-mentioned technical problems, the present invention proposes a cooling device for welding of automobile parts processing.

[0012] A third ring plate is provided on each of the two first ring plates on opposite sides; the two third ring plates include two third half rings; the two third half rings included in the two third ring plates correspond to each other and fit together, thereby forming a complete third ring plate;

[0013] The bottoms of each two opposite third half rings are rotatably connected by a hinge; the tops of each two opposite third half rings are locked and fixed by a locking bolt;

[0014] On the opposite side of the two first ring plates, evenly arranged bellows are fixedly connected to the two first half rings. The bellows are bendable and shaped bellows, and the other ends of the bellows are mounted on the opposite third half rings. A first support rod is mounted on each of the third half rings, and the first support rods pass through the third half rings.

[0015] A cooling assembly is provided between the two first ring plates and the third ring plate, and the cooling assembly is used to cool the pipeline during welding.

[0016] Preferably, each of the cooling components comprises two semi-annular capsules;

[0017] A semi-ring capsule is provided between each of the first semi-ring and the third semi-ring, and two adjacent semi-ring capsules correspond to each other and fit in place;

[0018] Each of the semi-annular capsules is provided with a liquid cavity; a liquid inlet pipe is fixedly installed on the top of each semi-annular capsule; a liquid outlet pipe is fixedly installed on the bottom of each semi-annular capsule, and both the liquid inlet pipe and the liquid outlet pipe are connected to the liquid cavity;

[0019] The semi-ring bags provided between the first semi-ring and the third semi-ring are both fixedly connected to the first semi-ring and the third semi-ring.

[0020] Preferably, each of the third half rings is provided with evenly arranged through grooves;

When the corrugated tube is bent, the position of the third half ring also changes with the corrugated tube, so that the position of the third ring plate can be changed according to the outer shape of the tube, thereby improving the scope of application of the welding mechanism and not being limited to welding straight tubes, thereby improving the practicality of the welding mechanism.

[0031] 3. The automotive parts processing welding cooling equipment described in the present invention, when the shielding gas flows from the half-slot position to the air outlet position, the shielding gas will flow along the pipe welding position. In the process of the shielding gas flowing along the welding position, the weld can be protected. At the same time, the flowing shielding gas can take away the harmful gases and smoke generated during welding, thereby preventing the harmful gases or smoke from spreading to the external environment, thereby posing a safety hazard to workers. At the same time, the shielding gas after use can be recycled, thereby reducing the cost of using the shielding gas. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0045] Example 1

[0046] like Figures 1 to 10 As shown, the automotive parts processing, welding and cooling equipment of the present invention includes a welding mechanism; the welding mechanism includes two first ring plates 1; the two first ring plates 1 each include two first half rings 101;

[0047] The two first half rings 101 included in the two first ring plates 1 correspond to each other and fit together to form a complete first ring plate 1; the bottoms of each two opposite first half rings 101 are rotatably connected by a hinge; the tops of each two opposite first half rings 101 are locked and fixed by a locking bolt;

[0048] An annular groove 11 is formed on the opposite end surfaces of the two first ring plates 1, and the cross section of the annular groove 11 is convex; two opposing second half rings 12 are provided between the two first ring plates 1; and half-ring sliders 13 are fixedly connected to the end surfaces of the two second half rings 12 facing the first half rings 101 on both sides, and the cross section of the half-ring sliders 13 is convex and slides in the annular groove 11;

[0049] The two second half rings 12 are respectively located between the two opposite first half rings 101; a half groove 14 is formed on the opposite side of the top of the two second half rings 12, and the two half grooves 14 form a complete circular groove;

[0050] A third ring plate 2 is provided on opposite sides of the two first ring plates 1; the two third ring plates 2 include two third half rings 201; the two third half rings 201 included in the two third ring plates 2 correspond to each other and fit together, thereby forming a complete third ring plate 2;

[0051] The bottoms of each two opposite third half rings 201 are rotatably connected by a hinge; the tops of each two opposite third half rings 201 are locked and fixed by a locking bolt;

[0052] On the opposite sides of the two first ring plates 1, evenly arranged bellows 21 are fixedly connected to the two first half rings 101. The bellows 21 are bendable and shaped bellows 21, and the other ends of the bellows 21 are mounted on the opposite third half rings 201. A first support rod 22 is mounted on each of the third half rings 201, and the first support rod 22 passes through the third half rings 201.

[0053] A cooling assembly is provided between the two first ring plates 1 and the third ring plate 2, and the cooling assembly is used to cool the pipe during welding;

[0054] In this embodiment, each of the cooling components includes two semi-annular capsules 3;

[0055] A semi-ring capsule 3 is provided between each of the first semi-ring 101 and the third semi-ring 201, and two adjacent semi-ring capsules 3 are correspondingly fitted to each other;

[0056] Each of the semi-annular capsules 3 is provided with a liquid cavity; a liquid inlet pipe 31 is fixedly installed on the top of each semi-annular capsule 3; a liquid outlet pipe 32 is fixedly installed on the bottom of each semi-annular capsule 3, and both the liquid inlet pipe 31 and the liquid outlet pipe 32 are connected to the liquid cavity;

[0057] The semi-ring capsule 3 provided between the first semi-ring 101 and the third semi-ring 201 is fixedly connected to the first semi-ring 101 and the third semi-ring 201;

[0058] Specifically, when assembling and welding different pipes, first, the two pipes are fixedly installed on the clamp, and then the end surfaces of the two pipes to be welded are aligned. Then the staff rotates the first half ring 101 and the third half ring 201. During the process of the first half ring 101 and the third half ring 201, the first half ring 101 and the third half ring 201 will rotate with the hinge as the center of the circle, and the first half ring 101 and the third half ring 201 will no longer fit together and gradually open. At the same time, the first half ring 101 and the third half ring 201 will also drive the half ring capsule 3 to rotate, and the opposite half ring capsule 3 will no longer fit together and gradually open. At the same time, the rotating first half ring 101 will drive the second half ring 12 to rotate, and the opposite second half ring 12 will no longer fit together and gradually open. Then, the welding mechanism can be installed on the two opposite pipes.

[0059] More specifically, during the installation of the welding mechanism, the first half ring 101, the second half ring 12, the third half ring 201 and the half ring capsule 3 are first transferred to the two opposite sides of the pipe, and the second half ring 12 is aligned with the end faces of the two pipes. Then, the position of the third half ring 201 is adjusted according to the outer contour of the pipe. If the welded pipe is an inclined pipe or a curved pipe, the different bellows 21 can be bent according to the outer contour of the pipe. The bellows 21 will automatically be shaped after being bent. When the bellows 21 is bent, the position of the third half ring 201 also changes with the bellows 21. When the position of the pipe is at the center of the third half ring 201, the bending of the corrugated tube 21 is stopped, and then the originally opened first half ring 101 and the third half ring 201 are rotated. During the rotation of the first half ring 101 and the third half ring 201, the second half ring 12 and the semi-annular capsule 3 are driven to rotate. When the first half ring 101, the second half ring 12, the third half ring 201 and the semi-annular capsule 3 are attached to each other, the locking bolts are used to lock the first half ring 101 and the third half ring 201. At this time, the first support rod 22 is just against the two pipes, and then the two pipes can be welded.

[0060] Furthermore, when welding the pipeline, first insert the two external pipelines into the liquid inlet pipe 31 and the liquid outlet pipe 32, and connect the pipeline inserted into the liquid inlet pipe 31 with the coolant, and at the same time pass the pipeline inserted into the liquid outlet pipe 32 into the collection box, and then pass the coolant into the liquid inlet pipe 31. When the coolant enters the liquid cavity, the semi-annular capsule 3 will gradually expand and eventually fit with the pipeline. When the semi-annular capsules 3 on both sides of the first semi-ring 101 are fitted with the pipeline, the space between the two cooling components is a closed space. Then the coolant in the semi-annular capsule 3 will flow out through the liquid outlet pipe 32 and flow into the collection box, so that the coolant circulates in the semi-annular capsule 3. Then the worker inserts the welding gun into the half groove 14, and then the relative pipelines can be welded. During welding, shielding gas will be ejected from the welding nozzle on the welding gun, and the ejected shielding gas will enter the enclosed space, and then the worker can weld the position where the two pipes are fitted together. During the welding process, the second half ring 12 can be pushed to rotate by the welding gun, and the second half ring 12 will push the half ring slider 13 to slide in the annular groove 11, so that the worker can push the second half ring 12 to rotate and weld around the fitting surfaces of the two pipes. At the same time, the coolant circulating in the half ring bag 3 can take away the heat generated during welding on the pipe, thereby avoiding the position where the pipe is welded from being in a high temperature state for a long time, which will cause an oxidation reaction at the position where the pipe is welded, resulting in pores in the weld, thereby affecting the welding quality.

[0061] Furthermore, after the welding is completed, the two second half rings 12 are manually pushed. When the second half rings 12 are rotated to the initial position, the locking bolts are then removed. Then, the first half ring 101, the second half ring 12, the third half ring 201 and the half ring capsule 3 are rotated relative to each other. When the first half ring 101, the second half ring 12, the third half ring 201 and the half ring capsule 3 are opened, the worker can remove the welding mechanism from the pipeline.

[0062] During the welding process of the two pipes, the semi-annular bag 3 is fitted with the pipes to form a sealed space between the two cooling components. When the shielding gas is in the sealed space, the shielding gas can be isolated from the outside air, and at the same time, excessive shielding gas can be prevented from diffusing to the outside, thereby reducing the protective effect of the shielding gas on the welding position. Therefore, it is necessary to increase the amount of shielding gas sprayed to achieve protection of the welding position, which will increase the cost of welding.

[0063] At the same time, since evenly arranged bellows 21 are installed between the adjacent first ring plate 1 and the third ring plate 2, when it is necessary to weld an inclined pipe or a curved pipe, the bellows 21 can be bent according to the outer contour of the pipe. When the bellows 21 is bent, the position of the third half ring 201 also changes with the bellows 21, so that the position of the third ring plate 2 can be changed according to the outer shape of the pipe, thereby improving the scope of application of the welding mechanism, and is not limited to welding straight pipes, thereby improving the practicality of the welding mechanism.

[0064] Example 2

[0065] Each of the third half rings 201 is provided with evenly arranged through slots 23;

[0066] The bellows 21 installed on the third ring plate 2 pass through the through groove 23 and extend to the side of the third half ring 201 away from the first half ring 101;

[0067] In this embodiment, a locking ring 24 is installed on each bellows 21 on the opposite sides of the two third ring plates 2;

[0068] Specifically, since the bellows 21 passes through the through groove 23, when the bellows 21 needs to be bent according to the outer contour of the pipe, the length of the bellows 21 between the first half ring 101 and the third half ring 201 can be adjusted according to the distance between the half ring and the third half ring 201. When adjusting the length of the bellows 21, the bellows 21 can be pushed to slide in the through groove 23, thereby adjusting the length of the bellows 21 between the first half ring 101 and the third half ring 201. This avoids the situation where the length of the bellows 21 is fixed, resulting in the need for a large bending range to adjust the position of the third ring plate 2.

[0069] Since a locking ring 24 is installed on the bellows 21, when the position adjustment of the third ring plate 2 is completed, the locking ring 24 is locked on the bellows 21, thereby blocking the third ring plate 2 and preventing the third ring plate 2 from sliding along the bellows 21.

[0070] Example 3

[0071] Each of the first half rings 101 is provided with a second support rod 15; each of the second support rods 15 is a threaded rod and is engaged with the first half ring 101 through a thread;

[0072] In this embodiment, the first support rod 22 is a threaded rod and is engaged with the third half ring 201 through threads;

[0073] Because the first half ring 101 is threadedly engaged with uniformly arranged second support rods 15, when the welding mechanism is mounted on the pipe, the second support rods 15 are rotated, gradually approaching the pipe until they abut against the pipe. During this process, the first half ring 101 and the second half ring 12 are supported, thereby preventing the first half ring 101 and the second half ring 12 from floating in the air. This prevents the second half ring 12 and the first half ring 101 from moving toward the pipe when the worker controls the welding gun to rotate the second half ring 12, thereby preventing the worker from affecting the welding process.

[0074] Since the first support rod 22 is a threaded rod, when the welding of two pipes is completed and other pipes need to be assembled and welded, the first support rod 22 and the second support rod 15 are rotated in opposite directions. The first support rod 22 and the second support rod 15 will gradually move away from the pipe and no longer abut against the pipe. At this time, the welding mechanism can be moved on the welded pipe. Then the staff will clamp the other pipes on the clamp and align the end faces of the pipes to be welded. Then, the welding mechanism will be moved to the position where the pipes are to be welded. Then, the first support rod 22 and the second support rod 15 will be rotated and abut against the pipes. Then, the welding of the pipes can continue.

[0075] Example 4

[0076] The two second half rings 12 are fixedly connected to a connecting layer 4 on the opposite end surfaces of the bottom, and the connecting layer 4 is made of high-temperature resistant rubber material;

[0077] A gas outlet 41 is fixedly mounted on the connecting layer 4;

[0078] In this embodiment, the second half ring 12 is made of transparent, high-temperature resistant polycarbonate material;

[0079] Specifically, since the two adjacent half-rings are fixedly connected with a connecting layer 4 on the end faces on one side opposite to the bottom, and an air outlet 41 is installed in the connecting layer 4, when welding, the external pipe is inserted into the air outlet 41, and the pipe inserted into the air outlet 41 is connected to the external gas tank. Therefore, when the shielding gas enters the inner ring of the second half-ring 12, as the shielding gas in the inner ring of the second half-ring 12 gradually increases, the shielding gas will gradually flow along the pipe to the position of the air outlet 41, and then the shielding gas will flow out through the air outlet 41, and the outflowing shielding gas will enter the gas tank through the air pipe;

[0080] During this process, when the shielding gas flows from the position of the half groove 14 to the position of the gas cylinder 41, the shielding gas will flow along the position of the pipeline welding. In the process of the shielding gas flowing along the welding position, the weld can be protected. At the same time, the flowing shielding gas can carry away the harmful gases and smoke generated during welding, thereby preventing the harmful gases or smoke from spreading to the external environment, thereby posing a safety hazard to the workers. At the same time, the shielding gas after use can be recycled, thereby reducing the cost of using the shielding gas.

[0081] Since the second half ring 12 is made of transparent high-temperature resistant polycarbonate material, during welding, the worker can directly observe the moving trajectory of the welding torch and the welding process of the welding section position.
