Description

Technical Field

[0001] This invention belongs to the field of heat exchanger technology, and in particular relates to a spatial irregular corrugated steel strip forming control device and method. Background Technology

[0002] The tube sheet perforations of heat exchangers are generally distributed in square, triangular, or annular patterns. In square and triangular distributions, the perforation bridges are consistent, and the relative positions of the heat exchange tubes are uniformly distributed according to a Cartesian coordinate system. During tube insertion, the support holes of the tube support plate are generally aligned with a portion of the tube sheet perforations. Positioning via the support holes of the tube support plate ensures uniform distribution of the heat exchange tubes within a specified space. However, in annular distributions, due to uneven perforation bridges and smaller bridge sizes, and the lack of a tube support plate structure, the gap between the heat exchange tubes after insertion needs to be controlled by installing gap positioning components. Therefore, these gap positioning components require high manufacturing precision and different specifications. Existing gap positioning components consist of multiple segments of irregularly shaped corrugated steel strips welded into a circle. Each segment is arc-shaped, including the arc-shaped corrugated steel strip and an arc-shaped steel strip welded to the outside of the corrugated steel strip. They are typically formed in one or more steps using a mold. The mold manufacturing cost is high, and one set of molds is only suitable for manufacturing one specification of irregularly shaped corrugated steel strip, lacking versatility.

The wave-shaped stamping die should be finished and heat treated, hardened and the like. Then the wave-shaped stamping die is used to stamp the steel strip into the corrugated steel strip.

If jamming occurs during the installation of the inspection pipe in a certain through hole or the assembly gap between the inspection pipe and the special-shaped corrugated steel strip exceeds the preset distance after the installation of the inspection pipe in a certain through hole, it indicates that the size of the special-shaped corrugated steel strip will change, and the size inspection of the special-shaped corrugated steel strip is unqualified, and the size of the special-shaped corrugated steel strip needs to be further adjusted. If there is no jamming during the installation of the inspection pipe in all through holes, and the assembly gap between each inspection pipe and the special-shaped corrugated steel strip does not exceed the preset distance after the installation of the inspection pipe in all through holes, it indicates that the size of the special-shaped corrugated steel strip has been fixed, and the size inspection of the special-shaped corrugated steel strip is qualified.

[0082] S724, if the jamming hole is located in the outer side of the special-shaped corrugated steel strip, the inspection pipe on the jamming hole is replaced with a second fixed pin, and it is judged whether the jamming hole intersects with the middle line of the line connecting the centers of two second through holes adjacent to the jamming hole, if yes, the inspection pipes on the two second through holes adjacent to the jamming hole are taken out, if not, the inspection pipe on the second through hole closest to the jamming hole is taken out;

[0083] S725, if the gap too large hole is located in the inner side of the special-shaped corrugated steel strip, it is judged whether the gap too large hole intersects with the middle line of the line connecting the centers of two first through holes adjacent to the gap too large hole, if yes, the inspection pipes on the two first through holes adjacent to the gap too large hole are replaced with second fixed pins, if not, the inspection pipe on the first through hole closest to the gap too large hole is replaced with a second fixed pin;

[0084] S726, if the gap too large hole is located in the outer side of the special-shaped corrugated steel strip, it is judged whether the gap too large hole intersects with the middle line of the line connecting the centers of two second through holes adjacent to the gap too large hole, if yes, the inspection pipes on the two second through holes adjacent to the gap too large hole are replaced with second fixed pins, if not, the inspection pipe on the second through hole closest to the gap too large hole is replaced with a second fixed pin;

[0085] S727, stand for a period of time, and complete the size adjustment of the special-shaped corrugated steel strip.

[0086] In steps S721 to S727, if there is jamming or scratching when installing the inspection pipe, it indicates that the size of the special-shaped corrugated steel strip at the position is too small, so the heat exchange pipe at the corresponding position on the other side of the special-shaped corrugated steel strip is replaced by the second fixing pin to expand the size at the jamming position. If the jamming hole is located on the inside of the special-shaped corrugated steel strip, i.e., the jamming hole is the second through hole, since the through holes on the limiting plate are uniformly distributed in an arc shape and the number of through holes in different groups is different, the number of through holes between adjacent two groups is not one-to-one corresponding. When adjusting the size, the position of the jamming hole is determined. Taking the case that the jamming hole is the second through hole as an example, if the middle line of the jamming hole and the center line of the two first through holes adjacent to the jamming hole intersects, it indicates that the jamming hole is located approximately in the middle of the two first through holes adjacent to the jamming hole, so the inspection pipe on the two first through holes adjacent to the jamming hole needs to be removed. In order to increase the size of the special-shaped corrugated steel strip at the jamming hole, a space is reserved. If the middle line of the jamming hole and the center line of the two first through holes adjacent to the jamming hole does not intersect, it indicates that the jamming hole is located approximately beside one first through hole, so only the inspection pipe on the first through hole closest to the jamming hole needs to be removed, which can reserve a space for increasing the size of the special-shaped corrugated steel strip at the jamming hole. Similarly, if the jamming hole is located on the outside of the special-shaped corrugated steel strip, i.e., the jamming hole is the first through hole, the inspection pipe on the two second through holes adjacent to the jamming hole or the inspection pipe on the second through hole closest to the jamming hole needs to be removed, which can reserve a space for increasing the size of the special-shaped corrugated steel strip at the jamming position.

[0087] If the assembly gap between the special-shaped corrugated steel strip and the inspection pipe exceeds the preset distance after installing the inspection pipe, it indicates that the size of the special-shaped corrugated steel strip at the position is too large, so the heat exchange pipe at the corresponding position on the other side of the special-shaped corrugated steel strip needs to be replaced by the second fixing pin to reduce the size at the gap position. If the gap hole is located on the inside of the special-shaped corrugated steel strip, the gap hole is the second through hole. Taking the case that the gap hole is the second through hole as an example, if the middle line of the gap hole and the center line of the two first through holes adjacent to the gap hole intersects, it indicates that the gap hole is located approximately in the middle of the two first through holes adjacent to the gap hole, so the inspection pipe on the two first through holes adjacent to the gap hole needs to be replaced by the second fixing pin to reduce the size of the special-shaped corrugated steel strip at the gap position. If the middle line of the gap hole and the center line of the two first through holes adjacent to the gap hole does not intersect, it indicates that the gap hole is located approximately beside one first through hole, so only the inspection pipe on the first through hole closest to the gap hole needs to be replaced by the second fixing pin, which can reduce the size of the special-shaped corrugated steel strip at the gap position. Similarly, if the gap hole is located on the outside of the special-shaped corrugated steel strip, i.e., the gap hole is the first through hole, the inspection pipe on the two second through holes adjacent to the gap hole or the inspection pipe on the second through hole closest to the gap hole needs to be replaced by the second fixing pin, which can reduce the size of the special-shaped corrugated steel strip at the gap position.

[0088] After the device is set according to the above process, a period of time is allowed to stand, so that the size of the special-shaped corrugated steel strip is fixed, and the size adjustment of the special-shaped corrugated steel strip is completed.

[0089] Further, in order to avoid moving the position of the arc-shaped steel strip during the size adjustment process, during the size adjustment process of the special-shaped corrugated steel strip, a plurality of first through holes are randomly selected without affecting the first through hole for size adjustment, and the heat exchange pipe on the selected first through hole is replaced with a first fixed pin. The position of the arc-shaped steel strip is fixed by the plurality of first fixed pins.

[0090] Further, the space special-shaped corrugated steel strip forming control method further comprises the following steps:

[0091] S8, repeating steps S1 to S7 to make a preset number of special-shaped corrugated steel strips, and sequentially welding the preset number of special-shaped corrugated steel strips to obtain a gap positioning piece;

[0092] S9, checking the size of each special-shaped corrugated steel strip of the gap positioning piece, if the size is unqualified, adjusting the size of the special-shaped corrugated steel strip until the size of the special-shaped corrugated steel strip is qualified.

[0093] In the above steps S8 and S9, after the size of each special-shaped corrugated steel strip is controlled, the size of the gap positioning piece obtained by sequentially welding the preset number of special-shaped corrugated steel strips is generally not a problem, so the size of the gap positioning piece can not be checked. Of course, in order to ensure that the size of the gap positioning piece meets the design requirements, the size of the gap positioning piece can also be checked. Specifically, the size of each special-shaped corrugated steel strip can be checked according to step S7, if the size is unqualified, the size of the special-shaped corrugated steel strip is adjusted until the size of the special-shaped corrugated steel strip is qualified, so as to ensure that the size of the gap positioning piece meets the design requirements.

[0094] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application, without departing from the technical solution of the present application, still belongs to the scope of the technical solution of the present application.
