Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, and in particular to an integrated pressing and transfer device for welding plate heat exchangers. Background Technology

[0002] The production of plate heat exchangers places stringent demands on welding processes. Traditional electric arc welding and resistance welding are inefficient, produce inconsistent quality, and are difficult to automate, hindering high-efficiency mass production. Laser welding, on the other hand, is gradually replacing traditional methods and becoming the mainstream choice for plate heat exchanger welding due to its high-quality welds, high-efficiency processing, good adaptability to refractory high-strength steels, simplified surface treatment process, and excellent automation and precise control capabilities.

[0003] Chinese patent CN223084003U discloses a welding device, which also includes a transfer device. The device first transfers the workpiece to be welded to a first predetermined welding station, clamps it, and performs welding. After welding is completed at the first predetermined welding station, the clamping is released, and the workpiece is transferred to a second predetermined welding station, and so on. After all welding is completed, the workpiece is then transferred to the starting loading station. This device has a complex predetermined welding station system. The transfer device does not include a clamping mechanism, making the transfer process prone to misalignment and the transfer path complex. Finally, the completed welded products must be transferred to the starting loading station, resulting in delays in timely loading and low efficiency.

[0004] Therefore, it is necessary to design a new utility model to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this utility model is to provide an integrated pressing and transferring device for welding plate heat exchangers, which can accurately position, press, and transfer the workpiece to be welded during welding, thereby ensuring the surface quality of the weld and improving welding efficiency.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: an integrated pressing and transferring device for welding plate heat exchangers, comprising a driving assembly, a transfer frame that moves horizontally along the X direction driven by the driving assembly, a first support plate fixedly disposed on the transfer frame and supporting one side of the workpiece in the X direction, a second support plate fixedly disposed on the transfer frame and supporting the other side of the workpiece in the X direction, a first pressing module located above the first support plate, and a second pressing module located above the second support plate.

[0007] Furthermore, the transfer frame includes a first crossbeam and a second crossbeam that are arranged opposite each other in the X direction and extend in the Y direction.

[0008] Furthermore, the first clamping module includes a plurality of first clamping components arranged along the Y direction on the first crossbeam.

[0009] Furthermore, the first clamping assembly includes a first cylinder and a first pressure plate that is driven to move up and down by the first cylinder.

[0010] Furthermore, the second clamping module includes a plurality of second clamping components arranged along the Y direction on the second crossbeam.

[0011] Furthermore, the second clamping assembly includes a second cylinder and a second pressure plate that is driven to move up and down by the second cylinder.

[0012] Furthermore, the area between the first clamping module and the second clamping module is hollowed out, and the area on the workpiece to be welded is located within this hollowed-out area.

[0013] Compared with the prior art, the advantages of this utility model of an integrated pressing and transferring device for welding plate heat exchangers are as follows: (1) The workpiece clamping and fixing function and the horizontal transfer function are highly integrated into the same device. By driving the transfer frame to move as a whole through the drive component, the workpiece that has been clamped on the support plate by the first clamping module and the second clamping module can be accurately transferred in the X direction. This eliminates the multiple independent steps and equipment for workpiece clamping and transfer in the traditional method, simplifies the operation process, and reduces the complexity of the equipment and the space occupied. (2) The hollow area design between the first pressing module and the second pressing module provides space for the welding support plate to be set below, so that the welding process can start immediately in the already positioned area while the transfer device positions the next sub-area to be welded to the welding station. Theoretically, the welding operation and the workpiece transfer and positioning can be carried out in parallel, further reducing the overall welding time. Attached Figure Description

Detailed Implementation

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0016] Please refer to Figures 1-3 This embodiment provides an integrated pressing and transferring device 100 for welding plate heat exchangers, which includes a driving assembly 1, a transfer frame 2 driven by the driving assembly 1 to move horizontally in the X direction, a first support plate 3 fixedly mounted on the transfer frame 2 and supporting one side of the workpiece in the X direction, a second support plate 4 fixedly mounted on the transfer frame 2 and supporting the other side of the workpiece in the X direction, a first pressing module 5 mounted on the transfer frame 2 and located above the first support plate 3, and a second pressing module 6 mounted on the transfer frame 2 and located above the second support plate 4.

[0017] In this embodiment, the workpiece to be welded is a plate heat exchanger. In other embodiments, the workpiece can also be other plates or sheets. In this embodiment, since the area to be welded on the heat exchanger is large, if the heat exchanger is fixed, the welding assembly needs to move a large area to complete all welding areas. Moreover, the heat exchanger can only be output as a whole after the welding assembly is completed, which is time-consuming and inefficient. Therefore, to solve this technical problem, this embodiment divides the area to be welded on the heat exchanger into multiple sub-areas, and then uses the transfer frame 2 to drive the heat exchanger to move, so that the multiple sub-areas on the heat exchanger sequentially reach the welding station, and the welding assembly completes the welding of all welding areas in batches. On the one hand, the transfer path of the welding assembly is shorter each time, which improves the welding efficiency. On the other hand, after the welding is completed, the heat exchanger is also unloaded, which further improves the welding efficiency.

[0018] Furthermore, if a single clamping plate is used for pressing, the large planar dimensions of the heat exchange fins can easily lead to uneven pressure distribution and insufficient clamping force in some areas, affecting the clamping effect. Therefore, it is advisable to use multiple independent clamping components to clamp the heat exchange fins separately to ensure that the workpiece obtains a uniform and reliable clamping state.

[0019] The transfer frame 2 includes a first crossbeam 21 and a second crossbeam 22 that are arranged opposite each other in the X direction and extend in the Y direction.

[0020] The first clamping module 5 includes a plurality of first clamping components 51 arranged along the Y direction. By setting the plurality of first clamping components 51 together to clamp one side of the workpiece in the X direction, uniform and reliable clamping of the workpiece on that side is achieved, providing necessary positioning and fixing guarantee for subsequent transfer operations.

[0021] The first clamping assembly 51 is arranged along the Y direction on the first crossbeam 21, including multiple first cylinders 511 and multiple first pressure plates 512 connected to each first cylinder 511 in a one-to-one correspondence. The clamping force on the workpiece is enhanced by the multi-cylinder-multi-pressure plate cooperative driving structure.

[0022] The second clamping module 6 includes a plurality of second clamping components 61 arranged along the Y direction. By setting the plurality of second clamping components 61 together to clamp the other side of the workpiece in the X direction, uniform and reliable clamping of that side of the workpiece is achieved. The first clamping module 5 and the second clamping module 6 work together to clamp the opposite sides of the workpiece in the X direction, respectively, and jointly ensure the positional stability of the workpiece during the transfer process.

[0023] The second clamping assembly 61 is arranged along the Y direction on the second crossbeam 22, including multiple second cylinders 611 and multiple second pressure plates 612 connected to each of the second cylinders 611 in a one-to-one correspondence. Similarly, this multi-cylinder-multi-pressure plate cooperative driving structure enhances the overall clamping force on the workpiece.

[0024] In this embodiment, the area between the first support plate 3 and the second support plate 4 is a hollow area, and the welding station is located within this hollow area. This hollow area design ensures that after the heat exchanger is placed on the first support plate 3 and the second support plate 4, neither the upper nor lower surfaces of the area to be welded are obstructed. This allows each sub-area to be welded on the heat exchanger to gradually move and settle onto the welding station for batch welding during the transfer process. Furthermore, it ensures that the pressing and transfer process and the welding process do not interfere with each other, further improving overall welding efficiency.

[0025] During operation, the heat exchanger is supported on both sides by the first support plate 3 and the second support plate 4. The first cylinder 511 drives the corresponding first pressure plate 512 to move downward, and at the same time, the second cylinder 611 drives the corresponding second pressure plate 612 to move downward, thereby pressing the heat exchanger against the corresponding support plate. In the pressed state, the drive assembly 1 drives the transfer frame 2 to carry the pressed workpiece and move horizontally along the X direction, and drives the first support plate 3 and the second support plate 4 to move synchronously, finally accurately transferring the area of ​​the heat exchanger to be welded to the welding station.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
