In order to facilitate an understanding of the present invention, a brazing pallet for an infrared burner will be described more fully below with reference to the accompanying drawings. Preferred embodiments of a brazing tray for an infrared burner are shown in the drawings. However, the brazing pallet for infrared burners may be implemented in many different forms and is not limited to the embodiments described herein. Rather, the purpose of these embodiments is to provide a more thorough and complete disclosure of a brazing tray for an infrared burner.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the brazing trays for infrared burners is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
As shown in fig. 1 and 2, the brazing tray for the infrared burner provided by the invention comprises a tray main body 1, wherein a limit post 2 is arranged on the tray main body 1, the limit post 2 comprises a limit table 21 for positioning the infrared burner 3 and a supporting table 22 for being matched with the tray main body 1, and the supporting table 22 is provided with a supporting surface 221 for bearing the infrared burner 3. As shown in fig. 3 and 4, the infrared burner 3 is an arc-shaped disc-shaped structure formed by winding an iron-chromium-aluminum sheet 31 with a stamping salient point 32, wherein the thickness of the iron-chromium-aluminum sheet is about 0.1 mm, and the stamping salient point 32 is closely contacted with adjacent layers of materials so as to ensure that a brazed product is firm, and after the limiting post 2 is arranged on the tray main body 1, the effective separation of the infrared burner 3 and the tray main body 1 is realized, the deformation caused by the contact of the infrared burner 3 and the tray main body 1 during brazing is avoided, the production quality of the infrared burner 3 is ensured, and the aim of high-efficiency production is achieved.
Specifically, the connection mode of the tray main body 1 and the spacing post 2 can be detachable connection or fixed connection, in this embodiment, the tray main body 1 and the spacing post 2 adopt the detachable connection mode, which can facilitate the production and manufacture of the tray main body 1 and the spacing post 2 respectively, and reduce the production cost. The limiting column 2 comprises a limiting table 21 and a supporting table 22, the limiting table 21 and the supporting table 22 are integrally formed, and the limiting table 21 and the supporting table 22 are contacted with the infrared burner 3, so that the limiting column 2 can be uniformly heated by adopting the integral forming, and deformation of the infrared burner 3 caused by uneven heating of the limiting table 21 and the supporting table 22 is avoided.
Further, as shown in fig. 2 and 6, the stopper 21 and the support 22 are coaxial cylindrical tables having different outer diameters, and the step formed between the stopper 21 and the support 22 is a support surface 221, and as shown in fig. 3 and 4, since the infrared burner 3 is an arc-shaped disk-like structure formed by winding an iron-chromium-aluminum thin plate 31 with a press bump 32 having a thickness of about 0.1 mm, a circular space (i.e., an inner ring of the infrared burner 3) is left in the center portion thereof, and in general, the size of the circular space is slightly larger than or equal to that of the stopper 21, so that the infrared burner 3 is placed on the stopper 21 in a sleeved manner, and the infrared burner 3 is supported by the support surface 221. Furthermore, the outer diameter of the limiting table 21 is matched with the inner ring of the infrared burner 3, which means that the outer diameter of the limiting table 21 is equal to the inner diameter of the circular space in the central part of the infrared burner 3, so as to further fix the infrared burner 3 and prevent the relative movement between the infrared burner 3 and the limiting post 2.
Further, as shown in fig. 2 and 6, the height of the support table 22 is 21.1mm to 21.5mm to avoid deformation of the infrared burner 3 by contact with the tray main body 1. Since the infrared burner 3 is in an arc-shaped disc structure after being wound, the central portion and the edge portion thereof have a height difference, and cannot be touched or pressed with force before brazing, deformation is easily generated, in order to ensure that the infrared burner 3 maintains a perfect original arc surface during the brazing high temperature process, the height of the limiting post 2 (mainly the height of the supporting table 22 for supporting and fixing the limiting table 21) should be designed according to the height difference between the central portion and the edge portion of the infrared burner 3, and in this embodiment, the height of the supporting table 22 is 22.3mm to achieve the optimal height for avoiding the contact between the infrared burner 3 and the tray main body 1, as shown in fig. 6. The height of the support table 22 is the height of the support table 22 after being mounted on the tray main body 1, and the height of the support table 22 is not counted because the stopper projection 23 provided at the bottom of the support table 22 as shown in fig. 6 is fitted into the stopper hole 11 after the stopper post 2 is mounted on the tray main body 1 as shown in fig. 5.
Furthermore, the limiting column 2 is prepared from ceramic materials, and the ceramic materials are high-temperature resistant, so that the limiting column 2 still has good supporting force at the high temperature of a brazing furnace, and bad deformation phenomena such as lower couch, upturned and the like caused by the limiting column 2 when the infrared burner 3 is heated in the brazing furnace are avoided.
