DETAILED DESCRIPTION

[0016] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiment of the utility model is described in detail below with reference to the drawings.

[0017] As Figure 1 And Figure 2As shown, the double-head flanging forming device provided by the embodiment of the application comprises a rack 1, a supporting seat 2 provided on the rack 1 and provided with a supporting groove, a pressing mechanism 3 provided on the rack 1, a lifting positioning mechanism 4 provided on the rack 1, straight guide rails 5 provided on the rack 1 and located on both sides of the supporting seat 2, two sliding punch assemblies 6 respectively in sliding connection with the two straight guide rails 5, a first driving mechanism 7 fixedly provided on the rack 1 and used for driving the two sliding punch assemblies 6 to slide synchronously, and two second driving mechanisms 8 symmetrically provided on the rack 1 and used for driving the two sliding punch assemblies 6 respectively.

[0018] In actual use, after the product 100 is placed on the supporting groove under the positioning of the lifting positioning mechanism 4 and is pressed by the pressing mechanism 3, the two ends of the product 100 to be flanged correspond to the two sliding punch assemblies 6, then the first driving mechanism 7 drives the two sliding punch assemblies 6 to move to a position where the product 100 can be impacted, and then the two second driving mechanisms 8 drive the two sliding punch assemblies 6 to impact the product 100. After each impact, the first driving mechanism 7 drives the sliding punch assemblies 6 to move by a unit distance, and then the second driving mechanism 8 drives the sliding punch assemblies 6 to impact the product 100 again. Until the product 100 is flanged and formed.

[0019] In the above design, the flanging of the two ends of the product 100 can be performed synchronously, and the work efficiency is effectively improved. By sliding of the sliding punch assemblies 6, different impact effects on the product are achieved, the product is ensured to be formed after multiple impacts, and the forming quality is effectively controlled.

[0020] Specifically, as shown in the drawings, Figure 2 The sliding punch assembly 6 comprises a plurality of springs 61, a sliding plate 62 slidingly provided on the straight guide rail 5, a mounting plate 63 fixedly provided on the sliding plate 62, a plurality of punches 64 in different specifications in sliding connection with the mounting plate 63, each punch 64 is connected with the mounting plate 63 through the spring 61, the plurality of punches 64 are arranged along the Y direction, the straight guide rail 5 extends along the Y direction, and the spring 61 extends along the X direction.

[0021] In actual use, when the first driving mechanism 7 drives the sliding punch assemblies 6 to move by a unit distance, the end of the product 100 corresponds to a different punch 64. When the second driving mechanism 8 drives the punch 64 to slide relative to the mounting plate 63 towards the end of the product 100, the punch 64 moves to drive the spring 61 to compress. When the second driving mechanism 8 is reset, the punch 64 is reset under the action of the spring 61.

[0022] In the above design, the structural design and specific implementation of the sliding punch assembly 6 can effectively achieve the successive impact on the product 100 and ensure the gradual realization of the flanging.

[0023] Specifically: Figure 2 As shown, the lifting and positioning mechanism 4 includes a lifting seat 41 connected to the frame 1 for sliding and lifting, a No. 1 cylinder 42 arranged on the frame 1 for driving the lifting seat 41 to move up and down, and two guide positioning pins 43 fixed at both ends of the lifting seat 41, and the two guide positioning pins 43 are respectively located at both ends of the supporting slot.

[0024] In actual use, the lifting base 41 is driven to rise by the No. 1 cylinder 42, so that the guide positioning pins 43 protrude from the frame 1 and are located at both ends of the supporting slot. Then, when the product 100 is placed, the two ends of the product 100 are positioned by the two guide positioning pins 43. Then it is reset and waits for the product 100 to impact.

[0025] In the above design, the structural design and specific implementation of the lifting and positioning mechanism 4 can effectively realize the positioning of the product 100.

[0026] Specifically: Figure 1 As shown, the clamping mechanism 3 includes a bracket 31 arranged on the frame 1, a No. 2 cylinder 32 arranged on the bracket 31, and a clamping block 33 arranged at the output end of the No. 2 cylinder 32. The clamping block 33 is provided with a clamping groove, and the clamping groove is used to clamp the outer wall of the product 100 exposed outside the supporting slot.

[0027] During actual use, the No. 2 air cylinder 32 drives the pressing block 33 to move downward, so that the pressing groove presses the product 100 .

[0028] In the above design, the structural design and specific implementation of the pressing mechanism 3 can effectively fix the product 100.

[0029] Specifically: Figure 2 As shown, the No. 2 driving mechanism 8 includes a fixed seat 81 fixed on the frame 1, a No. 3 cylinder 82 fixed on the fixed seat 81, and an abutment column 83 fixed on the output end of the No. 3 cylinder 82, and the abutment column 83 is used to abut with the side of the punch 64 away from the support seat 2.

[0030] In actual use, after the sliding punch assembly 6 moves into position, the No. 3 air cylinder 82 drives the abutment column 83 to move toward the corresponding punch 64 , so that the abutment column 83 pushes the punch 64 to impact the product 100 .

[0031] In the above design, the structural design and specific implementation of the No. 2 driving mechanism 8 can effectively realize the driving of the punch 64.

[0032] Specifically: Figure 2As shown, the first driving mechanism 7 comprises a connecting plate 72 connecting the sliding plates 62 of the two different sliding punch assemblies 6 and a screw nut pair 71 fixedly arranged on the rack 1 and used for driving the connecting plate 72 to move along the Y direction.

[0033] In actual use, the connecting plate 72 is driven to move by the screw nut pair 71, so that the connecting plate 72 drives the sliding plates 62 and the mounting plate 63 to move synchronously, thereby enabling the different punches 64 located on the mounting plate 63 to correspond to the end of the product 100.

[0034] In the above design, the structural design and the specific implementation of the first driving mechanism 7 can effectively realize the synchronous and rapid movement of the two sliding punch assemblies 6.

[0035] It should be understood that the above description is only a specific embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
