[0039] like Figure 4 and 5 As shown, product positioning assembly 110 includes a product positioning support assembly 111, a product lateral positioning assembly 112, and a product longitudinal positioning assembly 113. Both lateral positioning assembly 112 and longitudinal positioning assembly 113 are secured to product positioning support assembly 111 via screws and locating pins. Both lateral positioning assembly 112 and longitudinal positioning assembly 113 include positioning cylinders, with the two cylinders extending in perpendicular directions. Extension of the cylinder in lateral positioning assembly 112 achieves lateral positioning of the product, while extension of the cylinder in longitudinal positioning assembly 113 achieves longitudinal positioning of the product.

The front side of the brazing fixture pulling-out cylinder 121 is equipped with the brazing fixture expanding cylinder connector 122, and the brazing fixture expanding cylinder 123 is fixed on the brazing fixture expanding cylinder connector 122. After the brazing fixture expanding cylinder 123 is opened, the positioning and clamping of the brazing fixture can be completed. Combined with the retraction of the brazing fixture pulling-out cylinder 121, the pulling-out action of the brazing fixture after positioning and clamping can be achieved.
[0041] like Figure 8As shown, the wire cutting assembly 130 includes a scissor moving cylinder assembly 131, a scissor fixing plate 132, a scissor mechanism 133, a scissor assembly moving guide rail 134 and a scissor assembly moving guide rail support plate 135.

[0042] like Figure 9 and 10 As shown, the wire shaping, positioning, clamping, and separating assembly 140 includes a wire shaping, positioning, clamping, and separating assembly moving electric cylinder 141, a wire shaping, positioning, clamping, and separating assembly moving platform 142, and a wire shaping, positioning, clamping, and separating assembly moving platform support rail 143.

The wire shaping, positioning, clamping, and separating assembly moving platform 142 is movably mounted on the wire shaping, positioning, clamping, and separating assembly moving platform support rail 143 and is also connected to the wire shaping, positioning, clamping, and separating assembly moving electric cylinder 141. The movement of the wire shaping, positioning, clamping, and separating assembly moving electric cylinder 141 can drive the movement of the wire shaping, positioning, clamping, and separating assembly moving platform 142 on the wire shaping, positioning, clamping, and separating assembly moving platform support rail 143.
[0043] like Figure 11 As shown, the wire shaping, positioning, clamping, and separating assembly mobile platform 142 includes a wire shaping, positioning, clamping, and separating fixed assembly 1421, a wire positioning, clamping assembly 1422, and a wire shaping assembly 1423. The wire shaping, positioning, clamping, and separating fixed assembly 1421 is fixed to a slider on the wire shaping, positioning, clamping, and separating assembly mobile platform support guide rail 143. An internal cylinder and guide posts are mounted on the wire shaping, positioning, clamping, and separating fixed assembly 1421, and the internal cylinder and guide posts are connected to the wire positioning, clamping, and separating assembly 1422. The extension and retraction of the internal cylinder of the wire shaping, positioning, clamping, and separating fixed assembly 1421 enables the wire positioning, clamping, and separating fixed assembly 1422 to move up and down. The wire shaping, positioning, clamping, and separating fixed assembly 1421 is also fixedly mounted with the wire shaping, positioning, clamping, and separating fixed assembly 1423.
[0044] like Figure 12 As shown, the wire positioning clamping assembly 1422 includes a wire positioning clamping fixing plate 14221 and a wire clamping positioning cylinder assembly 14222. The wire clamping positioning cylinder assembly 14222 is fixed to the wire positioning clamping fixing plate 14221 through corresponding screw fixing holes.
[0045] like Figure 13 As shown, the wire shaping assembly 1423 includes a wire shaping cylinder fixing plate 14231, a wire shaping vertical cylinder 14232, a wire shaping cylinder 14233, and a wire shaping clamping jaw 14234. The wire shaping cylinder fixing plate 14231 is fixed to the wire shaping positioning, clamping, and separation fixing assembly 1421. The wire shaping vertical cylinder 14232 is fixed to the wire shaping cylinder fixing plate 14231. The wire shaping clamping jaw 14234 is fixed to the wire shaping cylinder 14233. The wire shaping cylinder 14233 is connected to the wire shaping vertical cylinder 14232. Closing the wire shaping cylinder 14233 can shape the wire, and retracting the wire shaping vertical cylinder 14232 can lift the wire after shaping.
[0046] like Figure 14 As shown, the integral support assembly 300 includes an integral support welding assembly 310 and a scrap wire storage cart 320. Guide wheels are designed on both sides of the integral support welding assembly 310 to manually push and unload the scrap wire storage cart 320. The scrap wire storage cart 320 is located below the automatic wire shearing platform and is used to store the scrap wire generated after processing.
[0047] During assembly of the heat exchanger's automatic wire-cutting mechanism, the first and second automatic wire-cutting platforms 100 and 200 are mounted on the integral support assembly 300 through corresponding positioning holes. The brazing fixture positioning and separation assembly 120, wire-cutting assembly 130, and wire-shaping positioning, clamping, and separation assembly 140 within the automatic wire-cutting platform 100 are all secured to the product positioning assembly 110 using screws and positioning pins.
[0048] The working process of the automatic wire cutting mechanism of the heat exchanger of the present invention includes the following steps: when the product with the brazing fixture and wire coming out of the brazing furnace is placed on the product positioning component 110, the cylinders in the product horizontal positioning component 112 and the product vertical positioning component 113 are extended respectively to complete the horizontal positioning and vertical positioning of the product.
[0049] The clamping and separation component moving electric cylinder 141 in the wire shaping, positioning, clamping and separation component 140 moves the wire shaping, positioning, clamping and separation component moving platform 142 as a whole to the product position, and the cylinder of the wire shaping, positioning, clamping and separation fixed component 1421 in the wire shaping, positioning, clamping and separation component moving platform 142 extends to allow the wire positioning, clamping component 1422 to be close to the product, and the wire clamping and positioning cylinder assembly 14222 clamps to complete the clamping action of the wire. The closing of the wire shaping cylinder 14233 can realize the shaping of the wire, and the retraction of the wire shaping up and down moving cylinder 14232 realizes the lifting of the wire after shaping.
[0050] While the iron wire is being shaped and clamped, the brazing fixture pulling-out cylinder 121 in the brazing fixture positioning and separation assembly 120 is extended and the brazing fixture opening cylinder 123 is opened, thereby achieving the clamping and positioning action of the brazing fixture.
[0051] After completing the shaping, positioning, clamping, and clamping, positioning, and positioning of the wire and the brazing fixture, the scissor moving cylinder assembly 131 in the wire cutting assembly 130 extends and moves the scissor mechanism 133 to the product wire position. The scissor mechanism 133 actuates to complete the cutting of the product wire. After the wire is cut, the wire at the bottom of the product falls into the waste wire placement cart 320. The cylinder of the wire shaping, positioning, clamping, and separating fixing assembly 1421 retracts, and the wire positioning, clamping, and separating assembly 1422 moves upward as a whole to lift the wire away from the product. The clamping and separation assembly moving electric cylinder 141 in the wire shaping, positioning, clamping, and separating assembly 140 moves the wire shaping, positioning, clamping, and separating assembly moving platform 142 as a whole to the wire discarding position, and places the wire inside the waste wire placement cart 320.
[0052] After the product is separated from the wire, the brazing fixture extraction cylinder 121 in the brazing fixture positioning and separation assembly 120 retracts and the brazing fixture expansion cylinder 123 opens, separating the brazing fixture from the product. The cylinders in the product transverse positioning assembly 112 and the product longitudinal positioning assembly 113 retract, releasing the product. The next step, removing the product and brazing fixture, can then proceed according to the process.
[0053] The automatic wire cutting mechanism of the heat exchanger of the present invention has the function of automatically cutting the wire on the product after the brazing furnace, and can also realize the function of automatically separating the brazing fixture and the product.
[0054] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
