A plate-fin heat exchanger welding device

Abstract

The application belongs to the technical field of welding equipment, in particular to a plate-fin heat exchanger welding equipment, which comprises a control base, a filling part arranged at the middle of the inner wall of the control base, a side clamping part for limiting the two side baffles, and a welding part; the filling part comprises three air-filling bottom cylinders. In order to ensure that the fin plate can be stably clamped between the two side baffle parts before welding, the pressure applied by the baffle part to the fin plate must be large, which may easily cause the fin plate to be bent and deformed. The device can erect the pre-welded fin plate between the two side baffle parts through the clamping effect of the adjacent expanded inner pads, thereby avoiding the problem that the fin plate is pressed and deformed when the baffle part clamps the fin plate, causing the contact parts at both ends of the fin plate to be skewed, and thus the structural stability of the heat exchanger after welding cannot be ensured.

[0034] The beneficial effects of the present application are as follows:

[0035] 1.

[0036] 2. Before the inflatable inner pad is inflated, it is stored in the form of a relatively thin film inside the storage plugboard, and the storage plugboard and the thin plugboard are relatively thin, so the upper part of the supporting plate can be inserted into the radiator with different intervals of fin plates, and the self-adaptive adjustment work is carried out according to the interval of the adjacent fin plates, so that the device can effectively assist in limiting the fin plates with different intervals, and the device has higher versatility.

[0037] 3. In the process of further maintaining the stable state of the partition plate and the clamped fin plate, the partition plate will inevitably cause extrusion to the fin plate, at this time, in order to avoid the extrusion bending deformation of the fin plate, after the fin plate contacts the partition plate, the built-in push plate will trigger the pressure sensor, and the stress of the internal partition plate is judged according to the display screen of the pressure sensor, in order to avoid the bending deformation of the fin plate, when the display value of the display screen reaches a certain value, the movement of the partition plate is immediately stopped, and thus in the case of ensuring that the fin plate is in close contact with the partition plate, the fin plate will not be bent and deformed due to excessive extrusion.

[0038] 4. After the partition plate is placed on the inner wall of the special frame shell, the wall-attached suction plate will be attached to the outer surface of the built-in push plate through the adsorption action of the sectional sliding shell front opening, thereby avoiding the partition plate from sliding out of the special frame shell, and during the welding work, since the welding point is inside the special frame shell, and the built-in push plate is not subjected to excessive extrusion and maintains a certain distance from the inner wall of the special frame shell, the wall-attached suction plate will suck away the toxic gas generated by welding through the suction ports on both sides of the sectional sliding shell, thereby reducing the problem of welding pollution.

[0062] The fin piece 5 is uniformly arranged on the outer surface of the partition piece 6, and the outer surface of the inflatable inner pad 26 is pressed with the outer surface of the fin piece 5.

[0063] Before the welding work of the heat exchanger is carried out by using the device, the partition piece 6 is placed in the special frame shell 31 on both sides, and then the partition piece 6 is pushed to the center part through the lateral pushing cylinder 14 on both sides, and the space suitable for inserting the fin piece 5 is reserved, as shown in the figure, the preparation work is completed, and then the lateral pushing cylinder 14 stops the pushing movement, so that the partition piece 6 on both sides maintains a fixed distance. Figure 3

[0064] ​Manually pull the distance adjustment slide cylinder 22 downward to make the distance adjustment slide cylinder 22 rise, at this time, the upper supporting plate 23 inserts the upper storage plug-in plate 25 into the position between the two side partition pieces 6, then the inflatable bottom cylinder 21 inflates the inflatable inner pad 26 inside the storage plug-in plate 25 through the thin plug-in plate 24 to make the two sides of the inflatable inner pad 26 expand, in this process, the fin piece 5 is vertically inserted into the position between the adjacent inflatable inner pads 26, then the fin piece 5 can be suspended in the air, i.e. the position between the two side partition pieces 6, under the clamping action of the two sides of the inflatable inner pad 26, adjust each fin piece 5 to make it keep in the vertical parallel state.

[0071] The side clamping component 3 further comprises:

[0072] ​The outer surface of the wall-attached suction plate 36 is fixedly connected with the middle part of the outer surface of the special frame shell 31. The outer surface of the wall-attached suction plate 36 is provided with a plug-in sleeve, and the lateral push cylinder 14 is plugged with the inner wall of the plug-in sleeve through a transverse push rod.

[0073] The segmented sliding shell 37 is fixedly connected with the inner cavity of the built-in push plate 32 through a slot on the side away from the wall-attached suction plate 36. The segmented sliding shell 37 is plugged with the inner cavity of the wall-attached suction plate 36 on the side close to the wall-attached suction plate 36. The sliding end outer surface of the segmented sliding shell 37 is provided with air ports, wherein the air ports on both sides are used for adsorbing welding fumes, and the air port on the front surface is used for adsorbing the attached baffle piece 6.

[0074] The welding component 4 comprises:

[0075] The inner cavity of the energy supply box 41 is uniformly provided with a bent welding rod 43. The energy supply box 41 directly supplies energy to the bent welding rod 43 through internal wires. The bent welding rod 43 is relatively thin and can be inserted into the gap of the adjacent fin plate piece 5. The top end of the bent welding rod 43 extends to the outside of the energy supply box 41, and the top end of the bent welding rod 43 is sleeved with a rotating wheel.

[0076] The inner wall of the transmission rotating belt 44 is rollingly connected with the outer surface of the rotating wheel, and the bottom of the outer surface of the transmission rotating belt 44 is slidably connected with the upper surface of the energy supply box 41.

[0077] The inverted rotating machine 45 is rollingly connected with the inner wall of the transmission rotating belt 44 at the bottom of the rotating shaft.

[0078] The welding component 4 further comprises:

[0079] The vertical push cylinder 46 is provided in a number of two, and the bottom end of the vertical push cylinder 46 is fixedly connected with the upper surface of the fixed bottom plate 11.

The deflection motor 42 can twist the energy supply box 41, so that the bent welding rod 43 is slightly deflected.

[0081] After the fin plate 5 contacts the partition plate 6, the built-in push plate 32 is pushed by the partition plate 6, and then the spring push rod 35 presses the pressure sensor 33.

During the welding work, since the welding point is inside the special frame shell 31, and the built-in push plate 32 is kept a certain distance from the inner wall of the special frame shell 31 due to no excessive extrusion, the wall-attached suction plate 36 will suck the toxic gas generated by welding through the suction ports on both sides of the sectional slide shell 37, thereby reducing the problem of welding pollution.

[0083] During the welding work, the vertical push cylinder 46 will pull down the vertical push cylinder 46, so that the upper bending welding rod 43 is inserted into the position between the adjacent fin plates 5. The energy supply box 41 supplies energy to the bending welding rod 43, and the bottom end of the bending welding rod 43 performs welding work from top to bottom on the contact surface of the fin plate 5 and the partition plate 6. After single welding is completed, the inverted rotating machine 45 controls the bending welding rod 43 to change the deflection angle uniformly by twisting the transmission rotating belt 44, so that the bottom end of the bending welding rod 43 changes direction and performs welding work on the other side, thereby ensuring that both sides of the fin plate 5 are effectively welded. In order to ensure that the bottom end of the bending welding rod 43 can contact the welding point, the deflection motor 42 can twist the energy supply box 41 by a certain amplitude, so that the bottom end of the bending welding rod 43 is closer to the partition plate 6, thereby avoiding the problems of missed welding and missed welding.
