[0002] A cross-flow fan is mainly composed of three parts: an impeller, an air duct and a motor. The air duct (i.e., the cross-flow fan casing) is generally formed by stamping a metal sheet.

[0003] In the prior art, crossflow fan casing processing typically involves manual assembly and punching, followed by riveting using a punch press. When assembling the fan casing's protrusions, which are stamped from sheet metal, the rivet protrusions are directly inserted into the baffle, with the rivet perforations perpendicular to the baffle. Therefore, the mold must be bent before riveting the protrusions, and then another mold must be replaced to rivet the protrusions to the baffle. This results in a complex operational process and requires two transfers of materials. Furthermore, two punch presses are used, which are large, noisy, and power-intensive. The two transfers required easily lead to material accumulation and a large space occupation.

[0105] The slide rail mounting plate 1101 is arranged on the middle left to right part of the rear side of the base plate 2, on which a slide rail slider 1105 is arranged, and the pressing mechanism bottom plate 1104 is arranged on the slide rail slider 1105; the adjusting screw seat 1103 is arranged on the left end of the slide rail mounting plate 1101, and the upper end of the adjusting screw 1102 is screwed on the upper end (for adjusting the sliding stroke of the pressing mechanism bottom plate 1104); the rebound ejector rod seat 1108 is arranged on the right end of the slide rail mounting plate 1101, and the rebound ejector rod 1104 with a cap head is screwed on the upper end of the adjusting screw seat 1103. 9 After the return spring 1107 is installed, it is inserted into the rebound push rod hole at the upper end of the rebound push rod seat 1108 from left to right; the adjusting screw 1102, the pressing mechanism bottom plate 1104 and the rebound push rod 1109 are at the same height, constituting a limit to the sliding stroke of the pressing mechanism bottom plate 1104; the pressing mechanism bottom plate 1104 is connected to the enclosure positioning assembly bottom plate 703 of the enclosure positioning assembly 7 through the assembly connecting plate 1106, so that the pressing rebound assembly 11 and the enclosure positioning assembly 7 form a linkage.

[0107] During use, first place the left baffle of the crossflow fan housing into the left baffle positioning groove 415 of the left front pressure plate 401, where it is positioned by the left baffle positioning pin 417 and held in place by the left baffle attraction magnet 416. Similarly, place the right baffle of the crossflow fan housing into the right baffle positioning groove 915 of the right front pressure plate 906, where it is positioned by the right baffle positioning pin 917 and held in place by the right baffle attraction magnet 916. Next, insert the lower end of the crossflow fan housing panel downward from the upper rear portion of the fixed panel positioning block 707, positioning it with the panel positioning pin 704 and the lower panel stop 708. Next, insert the fan housing tongue plate downward from the rear portion of the triangular tongue plate positioning block 706, positioning it with the tongue plate positioning block on the triangular tongue plate positioning block 706.

[0108] Next, start the left pressing component pressing cylinder 807 of the left pressing component 8 and the right pressing component pressing cylinder (not marked in the figure) of the right pressing component 10, and drive the left pressing component enclosure pressing block 803 and the right pressing component enclosure pressing block (not marked in the figure) at their lower ends to press the arc section of the upper part of the cross-flow fan casing enclosure onto the fan casing enclosure positioning platform above the fixed enclosure positioning block 707, so as to ensure the arc shape of the cross-flow fan casing.

[0109] Afterwards, the horizontal booster cylinder 101 of the horizontal booster cylinder assembly 1 is started, and its booster cylinder connector 104 pushes the left pressure block assembly 4 together with the left baffle of the cross-flow fan housing (under the specifications of the limiting slide assembly 3) to move to the right. As the left baffle of the cross-flow fan housing approaches the cross-flow fan housing enclosure and the fan housing tongue plate, the rivet protrusions at the left ends of the cross-flow fan housing enclosure and the fan housing tongue plate gradually enter the rivet protrusion holes on the left baffle of the cross-flow fan housing, and pass through to the initial bending slope 412 of the rivet protrusion of the left fan housing enclosure and the initial bending slope 418 of the rivet protrusion of the left fan housing tongue plate, thereby initially bending the rivet protrusions to 45°.

[0110] At the same time, since the enclosure positioning assembly 7 and the pressure forming rebound assembly 11 are connected as a whole together with the left pressure forming assembly 8 and the right pressure forming assembly 10 thereon, the transmission is carried out through the top plate 702 (the left top plate 702 supports the right lower part of the left front pressure plate 401), thereby driving the enclosure positioning assembly 7 (note: the slide rail of the enclosure slide rail slot 701 is stationary, and the slide groove moves) and the pressure forming rebound assembly 11 (note: the pressure forming mechanism bottom plate 1104 above the slide rail slider 1105 moves) together with the left pressure forming assembly 8 and the right pressure forming assembly 10 thereon to move to the right, so that the rivet protrusions on the right end of the cross-flow fan housing enclosure and the fan housing tongue plate gradually enter the rivet protrusion holes on the right baffle of the cross-flow fan housing, and pass through to the initial bending slope 912 of the right fan housing enclosure rivet protrusion and the initial bending slope 913 of the right fan housing tongue plate rivet protrusion, thereby also initially bending the rivet protrusion into 45°.

[0111] At the same time, the return spring 1107 of the compression-shaped rebound component 11 is compressed, accumulating compression energy.

[0112] As the booster cylinder connector 104 of the horizontal booster cylinder 101 continues to push, the left compression spring 404 is compressed, and the duckbill front section (i.e., the right end) of the left rivet pin 408 is pushed out of the left rivet pin hole 414, thereby tightening the rivet point that has been initially bent at 45 degrees. Similarly, the right compression spring 903 is also compressed, and the duckbill front section (i.e., the left end) of the right rivet pin 908 is pushed out of the right rivet pin hole 914, thereby also tightening the rivet point that has been initially bent at 45 degrees. At this time, the allowance cavity between the left front pressure plate 401 and the left middle pad 405 and the allowance cavity between the right front pressure plate 906 and the right middle pad 901 disappear, and the riveting of the rivet point is now complete.

[0113] Afterwards, the horizontal booster cylinder 101 retracts to the left and resets to the origin. Under the elastic force of the left compression spring 404 and the right compression spring 903, the accommodation cavity between the left front pressure plate 401 and the left middle pad 405 and the accommodation cavity between the right front pressure plate 906 and the right middle pad 901 are restored; at the same time, under the elastic force of the reset spring 1107, the compression rebound component 11 together with the left compression component 8 and the right compression component 10 and the enclosure positioning component 7 thereon also move to the left and reset to the origin; then, the left compression component clamping cylinder 807 of the left compression component 8 and the right compression component clamping cylinder of the right compression component 10 also retract and reset to the origin. Afterwards, the cross-flow fan casing that has been riveted and formed is removed, completing a complete riveting action.

[0114] The cross-flow fan housing flanging riveting mechanism of the present invention can be used in the production of cross-flow fans as tooling equipment for the production of cross-flow fan housings.
