Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, in particular to a plate-fin heat exchanger welding equipment. Background Art

[0002] Plate-fin heat exchangers are typically composed of baffles, fins, seals, and guide vanes. Fins, guide vanes, and seals are placed between adjacent baffles to form a sandwich called a channel. These sandwiches are stacked according to the flow of fluids and brazed together to form a plate bundle. The plate bundle is the core of the plate-fin heat exchanger and, along with the necessary headers, pipes, and supports, completes the plate-fin heat exchanger. During the production process of plate-fin radiators, welding equipment is required to weld the fins and baffles.

[0003] The existing publication number is CN222857091U, which is a plate-fin heat exchanger welding device. It is pre-assembled by inserting fins into the partitions on both sides and then performing welding. However, the fins are usually thin. In order to ensure that the fins can be clamped more stably between the partitions on both sides before welding, the pressure exerted by the partitions on the fins must also be relatively large. At this time, the two ends of the fins may bend and deform due to the large pressure, which may cause the fins to be unable to maintain a parallel state after welding, so improvement is needed. Summary of the Invention

[0004] In view of the problem that the fins in the prior art are prone to extrusion and bending deformation during welding, the technical solution adopted by the present invention is: a plate-fin heat exchanger welding device, comprising: Control base; A filling component is arranged in the middle of the inner wall of the control base; Side clamping parts, used to limit the partitions on both sides; Welding components; The filling component comprises: Inflatable bottom cylinders, the number of which is three, and the outer surface of which is arranged inside the control base through a receiving groove for blowing and inflating; The pitch-adjustable slide cylinder has a bottom end that is sleeved with the upper portion of the outer surface of the inflatable bottom cylinder, and the interior of the pitch-adjustable slide cylinder is a hollow structure. The pitch-adjustable slide cylinder is made of rubber material and can be extended or compressed by manual traction; An upper supporting plate, wherein the lower surface of the upper supporting plate is plugged into the top end of the pitch-adjusting slide cylinder through a docking interface, and thin inserts are evenly arranged on the upper surface of the upper supporting plate, and drainage openings are evenly opened in the inner cavity of the thin inserts; The storage plug-in plate has its lower surface fixedly connected to the upper surface of the upper support plate, and an expansion pad is provided in the inner cavity of the storage plug-in plate. The bottom of the expansion pad is connected to the top of the thin plug-in plate through a drainage port. The storage plug-in plate has the same thickness as the thin plug-in plate. In the non-working state, the expansion pad is retracted inside the storage plug-in plate. Figure 4 This is the state of the inflatable inner cushion after it is inflated.

[0005] Furthermore, the control base comprises: A fixed base plate, wherein horizontal slide rails are symmetrically provided on the front and rear sides of the upper surface of the fixed base plate; A side bracket, wherein the top of the inner wall of the side bracket is fixedly connected to a side push cylinder, and the axis of the inner wall of the side push cylinder is slidably connected to a transverse push rod; a partition member disposed inside the side clamp member; The fin plate members are evenly arranged on the outer surface of the partition member, and the outer surface of the expanded inner pad and the outer surface of the fin plate members are pressed against each other.

The built-in push plate is in a non-working state. Figure 6 As shown, the spring push rod is pushed away from the inner wall of the special frame shell by a certain reserved distance; The pressure sensor has one end of the spring push rod away from the built-in push plate plugged into the inner cavity of the pressure sensor, and a display screen is symmetrically provided on the outer surface of the pressure sensor. The outer surface of the pressure sensor is fixedly connected to the outer surface of the special frame shell. The pressure sensor can judge the pressure received by the partition part through the thrust received by the spring push rod, thereby avoiding excessive pressure received by the fin plate part.

[0007] Furthermore, the side clamping component further includes: The outer surface of the wall-adhering suction plate is fixedly connected to the middle part of the outer surface of the special frame shell. The middle part of the outer surface of the wall-adhering suction plate is provided with a plug-in sleeve, and the lateral push cylinder is plugged into the inner wall of the plug-in sleeve through a transverse push rod; The segmented sliding shell has a side away from the wall-attached suction plate and is fixedly connected to the inner cavity of the built-in push plate through a slot, and a side of the segmented sliding shell close to the wall-attached suction plate is plugged into the inner cavity of the wall-attached suction plate. The outer surface of the sliding end of the segmented sliding shell is provided with air ports, wherein the air ports on both sides are used to absorb welding fumes, and the air port on the front is used to absorb the fitted partition parts.

[0008] Furthermore, the welding component includes: An energy supply box, wherein the inner cavity of the energy supply box is evenly provided with bent welding rods. The energy supply box directly supplies energy to the bent welding rods through internal wires. The bent welding rods are relatively thin and can be inserted into the gaps between adjacent fin plates. The top ends of the bent welding rods extend to the outside of the energy supply box. The top ends of the bent welding rods are sleeved with a rotating wheel. A transmission belt, wherein the inner wall of the transmission belt is in rolling connection with the outer surface of the rotating wheel, and the bottom of the outer surface of the transmission belt is in sliding connection with the upper surface of the energy supply box; The inverted rotating machine has a bottom of a rotating shaft that is in rolling connection with the inner wall of the transmission belt.

[0009] Furthermore, the welding component further includes: Two vertical push cylinders are provided, and the bottom ends of the vertical push cylinders are fixedly connected to the upper surface of the fixed base plate; A sliding connecting frame, the bottom of the outer surface of the sliding connecting frame is slidably connected to the axis center of the inner wall of the vertical push cylinder, the top of the sliding connecting frame is fixedly connected to a deflection motor, the rotating shaft of the deflection motor is plugged into the inner cavity of the energy supply box, the outer surface of the inverted rotating machine is fixedly connected to the outer surface of the deflection motor through a clamp, and the deflection motor can twist the energy supply box to cause the bent welding rod to deflect slightly.

[0010] The beneficial effects of the present invention are as follows: 1. In order to ensure that the fin plate can be clamped more stably in the position between the partition plates on both sides before welding, the pressure exerted by the partition plates on the fin plate must also be relatively large, which can easily cause the fin plate to bend and deform. The device can use the clamping effect of adjacent expansion pads to set the pre-welded fin plate in the position between the partition plates on both sides, thereby avoiding the problem that the partition plates clamp the fin plate and press the fin plate to deform, causing the contact parts at both ends of the fin plate to deflect, and thus the structural stability of the heat exchanger after welding cannot be guaranteed.

[0011] 2. Before inflation, the expansion inner pad will be stored in the inside of the storage plug-in plate in a thin film-like form. The storage plug-in plate and the thin plug-in plate are relatively thin, so the upper part of the upper support plate can be inserted into the radiator with fin plates of different spacings, and adaptively adjust according to the spacing between adjacent fin plates, thereby ensuring that effective auxiliary limiting work can be performed on fin plates of different spacings, making the device more universal.

[0012] 3. In the process of further maintaining a stable state between the partition member and the fin member in the clamping state, the partition member will inevitably squeeze the fin member. At this time, in order to prevent the fin member from being squeezed and bent, after the fin member contacts the partition member, the built-in push plate will trigger the pressure sensor, and the force of the internal partition member will be judged according to the display screen of the pressure sensor. In order to avoid bending and deformation of the fin member, the movement of the partition member will be stopped immediately after the display reading on the display screen reaches a predetermined value. Then, while ensuring that the fin member is in close contact with the partition member, the fin member will not bend or deform due to excessive squeezing. 4. After the partition is placed on the inner wall of the special frame shell, the wall-adhering suction plate will use the adsorption effect of the front opening of the segmented sliding shell to make the partition fit and be adsorbed on the outer surface of the built-in push plate, thereby preventing the partition from sliding out of the inside of the special frame shell. During welding, since the welding point is located inside the special frame shell and the built-in push plate is not subjected to excessive squeezing and maintains a certain distance from the inner wall of the special frame shell, the wall-adhering suction plate will absorb the toxic gas generated by welding through the suction ports on both sides of the segmented sliding shell, thereby reducing the problem of welding pollution.

The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0016] Example 1, please refer to Figure 1-Figure 4 The present invention provides a technical solution: a plate-fin heat exchanger welding device, comprising: Control base 1; The filling component 2 is arranged in the middle of the inner wall of the control base 1; Side clamping parts 3, used to limit the partitions on both sides; Welding parts 4; The filling component 2 includes: Inflatable bottom cylinders 21, the number of inflatable bottom cylinders 21 is three, and the outer surface of the inflatable bottom cylinders 21 is arranged inside the control base 1 through a receiving groove for blowing and inflating; The pitch-adjustable slide 22 has a bottom end that is sleeved with the upper portion of the outer surface of the inflatable bottom cylinder 21, and the interior of the pitch-adjustable slide 22 is a hollow structure. The pitch-adjustable slide 22 is made of rubber material and can be extended or compressed by manual traction; The upper support plate 23 has its lower surface connected to the top of the pitch adjustment slide 22 through a docking interface, and thin inserts 24 are evenly arranged on the upper surface of the upper support plate 23, and drainage openings are evenly opened in the inner cavity of the thin inserts 24; The storage plug-in plate 25 is fixedly connected to the upper surface of the upper support plate 23 on the lower surface of the storage plug-in plate 25. The inner cavity of the storage plug-in plate 25 is provided with an expansion inner pad 26. The bottom of the expansion inner pad 26 is connected to the top of the thin plug-in plate 24 through the drainage port. The storage plug-in plate 25 has the same thickness as the thin plug-in plate 24. In the non-working state, the expansion inner pad 26 shrinks inside the storage plug-in plate 25. Figure 4 This is the state where the inflatable inner cushion 26 is inflated.

[0017] The control console 1 includes: A fixed base plate 11, with horizontal slide rails 12 symmetrically provided on the front and rear sides of the upper surface of the fixed base plate 11; A side bracket 13, the top of the inner wall of the side bracket 13 is fixedly connected to a side push cylinder 14, and the axis of the inner wall of the side push cylinder 14 is slidably connected to a transverse push rod; a partition member 6, disposed inside the side clamp member 3; The fin plate members 5 are evenly arranged on the outer surface of the partition plate member 6 , and the outer surface of the expansion inner pad 26 and the outer surface of the fin plate member 5 are pressed against each other.

[0018] Before using this device to weld the heat exchanger, first place the partition 6 inside the special frame shell 31 on both sides, and then push the partition 6 toward the center through the side push cylinders 14 on both sides to reserve a space suitable for inserting the fin 5. Figure 3 As shown, the preparation is completed, and then the lateral push cylinder 14 stops the pushing movement, so that the partition members 6 on both sides maintain a fixed distance.

[0019] Manually pull the pitch adjustment slide 22 below to raise the pitch adjustment slide 22. At this time, the upper support plate 23 inserts the upper storage plug-in plate 25 into the position between the partition members 6 on both sides. Then the inflatable bottom cylinder 21 inflates the expansion inner pad 26 inside the storage plug-in plate 25 through the fine plug-in plate 24, so that the two sides of the expansion inner pad 26 are expanded. In this process, the fin plate member 5 is vertically inserted into the position between adjacent expansion inner pads 26. Then, the fin plate member 5 can be suspended in the air under the clamping action of the expansion inner pads 26 on both sides, that is, the position between the partition members 6 on both sides, and each fin plate member 5 is adjusted to keep it in a vertical and parallel state.

[0020] Since the partition member 6 has not yet contacted the end portion of the fin member 5 at this time, in order to ensure the stability of welding, it is necessary to push the side clamping members 3 on both sides again to make the outer surface of the partition member 6 contact the end face of the partition member 6, and then the welding members 4 on both sides respectively weld the contact parts of the partition member 6 and the fin member 5. After welding is completed, pull out the welding member 4, and then inflate the bottom cylinder 21 to extract the air inside the expanded inner cushion 26, manually press down the distance adjustment slide 22, and remove the storage plug-in plate 25 from the position between the adjacent fin members 5, pull open the side clamping members 3 on both sides, and remove the welded plate-fin heat exchanger.

[0021] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: Based on embodiment 1, the side clamping component 3 includes: A special frame shell 31, the inner cavity of which is evenly provided with through-holes; A built-in push plate 32, the outer surface of which is slidably connected to the inner wall of the special frame shell 31; The spring push rod 35 extends to the interior of the special frame 31 through the through-hole, and the right end of the spring push rod 35 is fixedly connected to the outer surface of the built-in push plate 32. The built-in push plate 32 is in a non-working state. Figure 6 As shown, the spring push rod 35 is pushed away from the inner wall of the special frame shell 31 by a certain reserved distance; The pressure sensor 33 and the spring push rod 35 are connected to the inner cavity of the pressure sensor 33 at one end away from the built-in push plate 32. The outer surface of the pressure sensor 33 is symmetrically provided with a display screen 34. The outer surface of the pressure sensor 33 is fixedly connected to the outer surface of the special frame shell 31. The pressure sensor 33 can judge the pressure exerted on the partition member 6 by the thrust exerted on the spring push rod 35, thereby avoiding excessive pressure on the fin member 5.

[0022] The side clamping member 3 also includes: The outer surface of the wall-adhering suction plate 36 is fixedly connected to the middle part of the outer surface of the special frame shell 31. A plug-in sleeve is provided in the middle part of the outer surface of the wall-adhering suction plate 36, and the lateral push cylinder 14 is plugged into the inner wall of the plug-in sleeve through a transverse push rod; The segmented sliding shell 37 has a side away from the wall-attached suction plate 36 and is fixedly connected to the inner cavity of the built-in push plate 32 through a slot, and the side of the segmented sliding shell 37 close to the wall-attached suction plate 36 is plugged into the inner cavity of the wall-attached suction plate 36. The outer surface of the sliding end of the segmented sliding shell 37 is provided with air ports, wherein the air ports on both sides are used to absorb welding fumes, and the air port on the front is used to absorb the fitted partition member 6.

[0023] The welding component 4 includes: The energy supply box 41 has an inner cavity uniformly provided with bent welding rods 43. The energy supply box 41 directly supplies energy to the bent welding rods 43 through internal wires. The bent welding rods 43 are relatively thin and can be inserted into the gaps between adjacent fin members 5. The top ends of the bent welding rods 43 extend to the outside of the energy supply box 41. The top ends of the bent welding rods 43 are sleeved with a runner. The transmission belt 44 has an inner wall in rolling connection with the outer surface of the rotating wheel, and a bottom of the outer surface of the transmission belt 44 is in sliding connection with the upper surface of the energy supply box 41; The inverted rotating machine 45 has a bottom portion of a rotating shaft that is in rolling connection with the inner wall of the transmission belt 44 .

[0024] The welding component 4 also includes: There are two vertical push cylinders 46 , and the bottom ends of the vertical push cylinders 46 are fixedly connected to the upper surface of the fixed base plate 11 ; The sliding connecting frame 47 has the bottom of its outer surface slidably connected to the axis of the inner wall of the vertical push cylinder 46. The top of the sliding connecting frame 47 is fixedly connected to the deflection motor 42. The rotating shaft of the deflection motor 42 is plugged into the inner cavity of the energy supply box 41. The outer surface of the inverted rotating machine 45 is fixedly connected to the outer surface of the deflection motor 42 through a clip. The deflection motor 42 can twist the energy supply box 41 to cause the bent welding rod 43 to deflect slightly.

[0025] After the fin member 5 contacts the partition member 6, the built-in push plate 32 will be pushed by the squeezed partition member 6, and then the pressure sensor 33 will be pressed through the spring push rod 35. After the pressure sensor 33 is triggered, the force applied to the internal partition member 6 is judged according to the display screen 34 of the pressure sensor 33. In order to avoid bending and deformation of the fin member 5, the movement of the partition member 6 will be stopped immediately after the display reading of the display screen 34 reaches a predetermined value. Then, while ensuring that the fin member 5 is in close contact with the partition member 6, the fin member 5 will not bend and deform due to excessive squeezing.

[0026] After the partition member 6 is placed on the inner wall of the special frame shell 31, the wall-adhering suction plate 36 will be adsorbed on the outer surface of the built-in push plate 32 through the adsorption effect of the front opening of the segmented sliding shell 37, thereby preventing the partition member 6 from sliding out from the inside of the special frame shell 31. During welding, since the welding point is located inside the special frame shell 31 and the built-in push plate 32 is not subjected to excessive squeezing and maintains a certain distance from the inner wall of the special frame shell 31, the wall-adhering suction plate 36 will absorb the toxic gas generated by welding through the suction ports on both sides of the segmented sliding shell 37, thereby reducing the problem of welding pollution.

[0027] When performing welding work, the vertical push cylinder 46 will pull the vertical push cylinder 46 down, so that the upper bent welding rod 43 is inserted into the position between adjacent fin plate parts 5 respectively, and the energy supply box 41 supplies energy to the bent welding rod 43. The bottom end of the bent welding rod 43 performs top-down welding work on the contact surface of the fin plate part 5 and the partition part 6, and after a single welding is completed, the inverted rotating machine 45 will control the bent welding rod 43 to uniformly change the deflection angle through the form of a torsional transmission belt 44, so that the bottom end welding point of the bent welding rod 43 is turned, and welding work is performed on the position on the other side, thereby ensuring that effective welding work is performed on both sides of the fin plate part 5. In order to ensure that the bottom end position of the bent welding rod 43 can contact the welding point, the deflection motor 42 can be used to perform a certain amplitude of twisting movement on the energy supply box 41, so that the bottom end of the bent welding rod 43 is closer to the partition part 6, thereby avoiding the problem of empty welding and leaking welding.

[0028] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
