Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger processing technology, specifically relating to a welding and forming device for a full-ring heat exchanger core. Background Technology

[0002] During the production and processing of heat exchangers, support plates need to be welded to the outside of the heat exchanger pipes to support and fix the pipes. In the current technology, there is a lack of special devices for fixing the support plates, which means that operators can only hold and fix the support plates by hand when performing the welding operation. This not only affects the welding efficiency, but also easily causes burns to the operator's hands. Especially in the production and processing of full-ring heat exchangers, the curvature of the core and fin distribution makes it difficult to effectively and stably fix the regulating plates manually. At the same time, it is also impossible to stably press the support plates to eliminate the gap between the support plates and the pipes, which increases the welding difficulty. Utility Model Content

[0003] The purpose of this invention is to provide a forming device for stably clamping the internal support plates of a full-ring heat exchanger to improve welding efficiency and welding effect.

[0004] The specific technical solution adopted by this utility model is as follows: A welding and forming device for a full-ring heat exchanger core includes an arc-shaped fixing plate, two pressure blocks for fixing the heat exchanger core, and two pressure strips for fixing the heat exchanger support plates. Each pressure strip has a screw hole at both ends, and the four screw holes are threadedly connected to four bolts. Each of the four pressure blocks has a sleeve hole at its end, and the four sleeve holes are respectively sleeved with the upper ends of the four bolts.

[0005] Furthermore, the end optical axes of the four bolts are rotatably connected to the upper ends of the four fixed top blocks via bearings.

[0006] Furthermore, the bottom ends of the four fixed top blocks are welded and fixed to the outer side of the arc-shaped fixed plate.

[0007] Furthermore, the bottom ends of the four bolts are respectively threaded to the four screw holes, and the four screw holes are all located at the top of the arc-shaped fixing plate.

[0008] Furthermore, the outer side of the arc-shaped fixing plate overlaps with the bottom surface of the full-ring heat exchanger core, and the upper surface of the full-ring heat exchanger core simultaneously contacts four pressure blocks.

[0009] Furthermore, the two pressure strips overlap with the front and rear ends of the full-ring heat exchanger fins, respectively.

[0010] Furthermore, the right end of the arc-shaped fixing plate has two grooves for accommodating the connecting pipes of the full-ring heat exchanger.

[0011] The technical effects achieved by this utility model are as follows: This utility model is applicable to the auxiliary fixing of the adjusting plate inside the full ring heat exchanger during welding. In use, multiple pressure blocks can be used to effectively fix the core of the full ring heat exchanger, and two pressure strips can be used to squeeze the fins of the full ring heat exchanger to clamp and fix the adjusting plate in the gap between the fins. This makes it easier for operators to weld the adjusting plate to the fins, improves welding efficiency, and eliminates the gap between the fins and the adjusting plate, achieving tight welding and improving the welding effect.

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0015] like Figure 1-3 As shown, a full-ring heat exchanger core welding and forming device includes an arc-shaped fixing plate 1, two pressure blocks 8 for fixing the heat exchanger core and two pressure strips 2 for fixing the heat exchanger support plates. Each pressure strip 2 has screw holes 5 at both ends, and the four screw holes 5 are threadedly connected to four bolts 4 respectively. Each of the four pressure blocks 8 has a sleeve hole 9 at its end, and the four sleeve holes 9 are respectively fitted with the upper ends of the four bolts 7. When using this device to assist in welding the adjusting plates inside the full ring heat exchanger 10, the user can place the core of the full ring heat exchanger 10 on the arc-shaped fixing plate 1. At this time, the user can pull the pressure block 8 to rotate so that the end of the pressure block 8 rotates above the core of the full ring heat exchanger 10. Then, rotate the bolts 7 so that the bolts 7 descend along the screw hole 2 to press the pressure block 8. When the pressure block 8 is in close contact with the core of the full ring heat exchanger 10, stop rotating the bolts 7. In this way, the multiple pressure blocks 8 can effectively fix the core of the full ring heat exchanger 10, ensuring the stability of the full ring heat exchanger 10 during the welding process.

[0016] The end shafts of the four bolts 4 are rotatably connected to the upper ends of the four fixed top blocks 3 via bearings. Users can adjust the height of the adjusting plate between the fins and rotate the bolts 4 to bring the two pressure strips 2 closer to each other along the four bolts 4. When the two pressure strips 2 are tightly fitted with the fins of the full-ring heat exchanger 10 and a certain pressure is applied to the fins so that the adjusting plate is tightly fitted with the fins, the rotation of the bolts 4 is stopped. Thus, the adjusting plate is clamped and fixed in the gap between the fins by the compression of the fins of the full-ring heat exchanger 10 by the two pressure strips 2, which facilitates the operator to perform welding operations on the adjusting plate and the fins, improves welding efficiency, and eliminates the gap between the fins and the adjusting plate, achieving tight welding and improving the welding effect.

[0017] The bottom ends of the four fixed top blocks 3 are all welded and fixed to the outer side of the arc-shaped fixed plate 1.

[0018] The bottom ends of the four bolts 2 7 are respectively threaded to the four screw holes 2, and the four screw holes 2 are all opened at the top of the arc-shaped fixing plate 1.

[0019] The outer side of the arc-shaped fixing plate 1 overlaps with the bottom surface of the core of the full-ring heat exchanger 10. The upper surface of the core of the full-ring heat exchanger 10 is in contact with four pressure blocks 8 at the same time. The arc of the arc-shaped fixing plate 1 is consistent with the radius of the full-ring heat exchanger 10, so that the arc-shaped fixing plate 1 can be used to achieve stable support and fixation of the full-ring heat exchanger 10.

[0020] The two pressure strips 2 overlap with the front and rear ends of the fins of the full-ring heat exchanger 10, respectively.

[0021] Two grooves 6 are provided on the right end of the arc-shaped fixing plate 1 to accommodate the connecting pipes of the full-ring heat exchanger 10.

[0022] The working principle of this utility model is as follows: When using this device to assist in welding the adjusting plates inside the full-ring heat exchanger 10, the user can place the core of the full-ring heat exchanger 10 on the arc-shaped fixing plate 1, and make the two connecting pipes of the full-ring heat exchanger 10 respectively located in the two grooves 6. At this time, the user can pull the pressure block 8 to rotate so that the end of the pressure block 8 rotates to the top of the core of the full-ring heat exchanger 10, and then rotate the bolt 7 to make the bolt 7 descend along the screw hole 2 to press the pressure block 8. When the pressure block 8 is in close contact with the core of the full-ring heat exchanger 10, stop rotating the bolt 7. Then the user can adjust the height of the adjusting plate between the fins and rotate bolt 4 so that the two pressure strips 2 move closer to each other along the four bolts 4 respectively. When both pressure strips 2 are tightly attached to the fins of the full ring heat exchanger 10 and a certain pressure is applied to the fins so that the adjusting plate is tightly attached to the fins, stop rotating bolt 4. At this time, the user can perform welding operations on the adjusting plate and the fins.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
