[0037] See also Figure 1-Figure 5A punching and trimming tool for automobile air ducts includes a tool frame 1, and air duct workpieces 104 to be punched and trimmed are arranged on both sides of the tool frame 1. The two sides of the air duct workpiece 104 are fixed to the tool frame 1 by clamping tools 102 for punching and trimming. Trimming mechanisms 103 are arranged at both ends of the air duct workpiece 104 to trim the two end surfaces of the air duct workpiece 104, and punching mechanisms 101 are arranged on both sides of the air duct workpiece 104 to punch holes on both sides of the air duct workpiece 104.

Clamping tools 102 for fixing the two ends of the air duct workpiece 104 are provided on both sides of the tooling frame 1. After fixation, the two ends of the air duct workpiece 104 are trimmed by trimming mechanisms 103 provided on both sides of the air duct workpiece 104. The air duct workpiece 104 at the upper and lower ends completes the punching operation on the two ends, so that when two groups of workpieces are processed simultaneously, the stability of the processing can also be ensured.

[0040] In the specific implementation process, the tooling frame 1 is composed of an upper frame plate 402, a trimming mechanism 103 and a lower frame plate 403, which can allow the duct workpiece 104 to be punched and trimmed after processing and fixing, thereby ensuring stability. The movable frame 404 is the center, the upper frame plate 402 is located above it, and the lower frame plate 403 is located below. The third hydraulic mechanism 405 is inverted and installed on both sides of the upper frame plate 402. The third hydraulic mechanism 405 controls the hydraulic rod downward. The movable frame 404 is extended to push the movable frame 404 downward, and the air duct workpiece 104 is completely pressed between the lower frame plate 403 and the movable frame 404 to ensure the stability of the workpiece during processing. Since the surroundings between the upper frame plate 402 and the lower frame plate 403 are supported and fixed by the slide rod 406, when the third hydraulic mechanism 405 controls the hydraulic rod to return, the movable frame 404 is driven to move along the outside of the slide rod 406, and the entire movable frame 404 is lifted to remove the workpiece between the movable frame 404 and the lower frame plate 403.

[0041] The punching mechanism 101 provided in the present application is composed of a second hydraulic mechanism 4 and a punching head 401. In actual application, six groups are provided, four of which are connected to a movable frame 404, wherein the second hydraulic mechanism 4 is mounted invertedly on the movable frame 404 by a bracket, and the extension of the hydraulic rod of the second hydraulic mechanism 4 is controlled downward to cause the punching head 401 to punch holes on one side of the air duct workpiece 104 located on both sides of the lower frame plate 403, and the other two groups are connected to the lower frame plate 403, wherein the second hydraulic mechanism 4 is mounted on both sides of the lower frame plate 403 by a bracket, and the extension of the hydraulic rod of the second hydraulic mechanism 4 is controlled upward to lift the punching head 401 to punch holes on the other side of the air duct workpiece 104 located on both sides of the lower frame plate 403.

The clamping member 2 is fixed on the movable frame 404, and the clamping platform 201 is fixed on the lower frame plate 403. When the entire movable frame 404 is lifted, the clamping member 2 can be lifted, and the fixation of the air duct workpiece 104 can be released at the same time, and the workpiece can be taken out.

[0043] The trimming mechanism 103 provided in the present application is composed of a first hydraulic mechanism 3 and a trimming knife 301. In actual application, four groups are provided, two groups are provided in the middle of the lower frame plate 403 and the movable frame 404, and the other two groups are provided on both sides. The first hydraulic mechanism 3 provided in the middle is invertedly installed on the lower frame plate 403 to control the extension of the hydraulic rod of the first hydraulic mechanism 3 upward to lift the trimming knife 301 to perform trimming on the air duct workpiece 104 on that side.

When trimming outward, waste chips are directly dropped into the waste collecting frames 303 to avoid being directly ejected from the openings on both sides of the tooling frame 1 to cause safety problems.

[0046] See also Figure 4 , Figure 5 and Figure 7 In the present application, an inner card slot 304 matching with the card block 305 is opened on the waste collecting frame 303. When the waste collecting frame 303 is inserted and installed along the side of the limiting frame 302, the card block 305 is driven to move in the same direction inside the inner card slot 304 until the card block 305 fits with the inner wall of the inner card slot 304. Then, the waste collecting frame 303 is positioned and installed on the limiting frame 302 for subsequent disassembly and assembly.
