DETAILED DESCRIPTION

[0024] Embodiment 1

[0025] like Figure 1-Figure 3 As shown, the utility model provides a punching device for muffler processing, comprising a frame 1, a punching mechanism 3, a support sleeve 4, a rotating roller 5 and a fixing device;

[0026] The punching mechanism 3 is arranged on the frame 1; the support sleeve 4 is arranged on the frame 1 and is located below the punching mechanism 3; the rotating roller 5 is rotatably arranged on the support sleeve 4, and a servo motor 9 for driving the rotating roller 5 to rotate is arranged on the support sleeve 4; the fixing device is slidably arranged on the rotating roller 5. The rotating roller 5 is provided with a receiving groove, and there are multiple receiving grooves; the fixing device includes multiple abutment plates 6 corresponding to the receiving grooves and all slidably arranged at the receiving grooves, and an adjustment mechanism 7 arranged in the rotating roller 5 for driving the multiple abutment plates 6 to move synchronously at the same time. The rotating roller 5 is provided with an inspection plate; the inspection plate is located on the side away from the support sleeve 4 and is detachably connected and clamped with the rotating roller 5.

[0027] In this embodiment, the muffler is inserted from the rotating roller 5 onto the supporting sleeve 4, so that the part to be punched is located on the supporting sleeve 4, and the abutment plate 6 is driven to move by the adjusting mechanism 7 so that the abutment plate 6 abuts against the inner wall of the muffler, and the muffler is clamped and fixed, and the position of the punching knife 303 is adjusted according to the processing needs, and the muffler is punched by the punching mechanism 3. After a row of holes are punched out, the rotating roller 5 is driven to rotate by the servo motor 9, and the rotating roller 5 drives the abutment plate 6 to move, and the abutment plate 6 drives the muffler to rotate. The muffler can be rotated to a specified angle and a second punching process can be performed. After multiple rotations, until the entire muffler is punched, the abutment plate 6 is driven by the adjustment mechanism 7 to be stored in the storage groove, thereby releasing the limit on the muffler and allowing the muffler to be removed; the support sleeve 4 can support the muffler during punching to prevent the muffler from deforming during punching, and when the abutment plate 6 drives the muffler to rotate, the support sleeve 4 can slide with the muffler to perform a simple grinding process on the burrs of the punching.

[0028] Embodiment 2

[0029] like Figure 1-Figure 3 As shown, the punching device for muffler processing proposed by the utility model, compared with the first embodiment, the punching mechanism 3 in this embodiment includes a telescopic cylinder 301 arranged on the frame 1, a push plate 302 slidably arranged on the frame 1 and connected to the output end of the telescopic cylinder 301, and a plurality of punching knives 303 slidably arranged on the push plate 302 and engaged with the push plate 302. The frame 1 is provided with a support frame 2, which is connected to a support sleeve 4, and the upper end of the support frame 2 is in a V-shaped structure and abuts against the side wall of the support sleeve 4; the support sleeve 4 is provided with a punching groove 401, and the punching groove 401 is located below the punching knife 303.

[0030] In this embodiment, the position of the punching knife 303 on the push plate 302 is adjusted according to the design requirements, and is fixed by bolts after the position adjustment is completed. When punching, the push plate 302 is driven downward by the telescopic cylinder 301, and the push plate 302 drives multiple punching knives 303 to move synchronously, so that the punching knife 303 contacts the muffler to perform punching processing until the lower end of the punching knife 303 penetrates the muffler and is embedded in the punching groove 401. The punching groove 401 provides space for the punching knife 303 to move, so that the punched waste can be discharged; since the upper end of the punching mechanism 3 is a V-shaped structure, it will not affect the waste discharge operation.

[0031] Embodiment 3

[0032] like Figure 1-Figure 3 As shown, the punching device for muffler processing proposed by the utility model, compared with the first or second embodiment, the adjustment mechanism 7 in this embodiment includes a plurality of push racks 704 respectively arranged on a plurality of abutment plates 6, a guide rack 8 arranged in the rotating roller 5 and slidably connected to the push rack 704, and a driving assembly arranged on the guide rack 8 for driving the push rack 704 to move. The driving assembly includes a driving motor 701 arranged on the guide rack 8, a gear 702 connected to the output end of the driving motor 701, and a plurality of racks 703 respectively arranged on a plurality of push racks 704 and staggeredly meshed with the gear 702.

[0033] In this embodiment, when the muffler is clamped, the gear 702 is driven to rotate by the driving motor 701, the gear 702 drives the rack 703 to move, the rack 703 drives the pushing frame 704 to move, and the guide frame 8 guides the pushing frame 704, so that the pushing frame 704 can push the abutment plate 6 to move, so that the abutment plate 6 can move toward the outside, so that the abutment plate 6 abuts against the inner wall of the muffler to clamp and fix the muffler. Since the diameter of the outer ring of the rotating roller 5 is smaller than the diameter of the outer ring of the supporting sleeve 4, when the muffler is disassembled, it is only necessary to retract the abutment plate 6 into the storage groove through the adjusting mechanism 7, so that when the muffler is disassembled, the abutment plate 6 will not interfere with the muffler.

[0034] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
