The short side rivet support includes a straight side pinch mounting plate 201 and a shelf plate 101. The straight edge clamping mounting plate 201 is mounted on the mechanical arm, so that the roller refrigerator liner double-short-side corner line riveting mechanism of the embodiment is integrally mounted on the mechanical arm. While the straight edge jaw mounting plate 201 is also used to mount a straight edge jaw mechanism. Two straight edge clamping mechanisms of the two horizontal edge riveting mechanisms are respectively arranged on two sides of the straight edge clamping mounting plate 201. The shelf 101 has two pieces. The two shelf boards 101 are parallel to each other and vertically mounted on the straight edge jaw mounting plate 201. The straight-edge pressing plate bending mechanism and the pressing plate driving mechanism of the two horizontal edge riveting mechanisms are respectively arranged on two sides of the two frame plates 101. The shelf 101 is provided with a clamping hole 102. The axis of the side pressing wheel 341 is vertical and is arranged at the outer side of the straight-side pressing plate bending mechanism.
The straight edge pressing plate bending mechanism comprises a straight edge pressing plate die strip 311, a straight edge bending die strip 321 and a straight edge driving frame 302. The straight-side driving rack 302 is mounted on the side of the rack board 101 through a vertical guide rail 303, and can be lifted and lowered along the vertical guide rail 303. The straight edge platen die strip 311 is mounted under the straight edge drive frame 302 by a spring post mechanism 312. The straight edge bending die strip 321 is a horizontally arranged roller. The roller is mounted at both ends below the straight edge drive frame 302 by a rolling shaft. Specifically, a support plate 323 is installed below the straight-edge driving frame 302, and roller mounting plates 322 are respectively arranged at two ends of the support plate 323. Both ends of the straight-side bending die bar 321 are respectively arranged on the roller mounting plate 322 through a rolling shaft and are positioned below the support plate 323. The straight-side bending die strip 321 is positioned on the inner side of the straight-side pressing die strip 311, and is clung to and parallel with the straight-side pressing die strip 311. The straight edge clamping mechanism is positioned on the inner side of the straight edge bending die strip 321 and is parallel to the straight edge bending die strip 321. The straight edge clamping mechanism is positioned on the inner side of the straight edge bending die strip 321 and is parallel to the straight edge bending die strip 321. The platen driving mechanism includes a driving cylinder 301. The drive cylinder 301 is mounted on the side of the frame plate 101 by a mounting plate and is located above the straight edge drive frame 302. The piston of the driving cylinder 301 is connected to the straight-side driving frame 302 so that the straight-side driving frame 302 can be lifted and lowered by the driving of the driving cylinder 301. The side pinch roller 341 is located outside the straight edge driving frame 302 and at the front end of the straight edge driving frame 302 by an L-shaped mounting plate 342.
The straight edge clamping mechanism is located on the inner side of the straight edge bending die strip 321 and comprises a straight edge clamping guide plate 220, a straight edge clamping block 211 and a spring mechanism. The straight edge clamping guide plate 220 and the straight edge clamping block 211 are strip-shaped bodies, are both arranged on the straight edge clamping mounting plate 201 and are parallel to the straight edge pressing plate die strip 311 and the straight edge bending die strip 321. The straight edge nip guide plate 220 is located at the side edge of the straight edge nip mounting plate 201, and forms an L-shaped structure with the straight edge nip mounting plate 201. A guide slope 221 is provided at the outer side surface of the straight edge nip guide plate 220. The straight edge jaw 211 is located inside the L-shaped structure and is mounted to the side of the straight edge jaw mounting plate 201. A straight edge nip gap 222 is provided between the straight edge nip block 211 and the straight edge nip guide plate 220. The straight edge jaw guide plate 220 protrudes outward from the straight edge jaw clamp block 211 such that a stepped gap 223 is provided between the straight edge jaw guide plate 220 and the straight edge jaw clamp block 211. The front and rear ends of the straight edge jaw clamp block 211 are respectively mounted on the swing block 212. The straight edge clamping blocks 211 are installed at the outer ends of the two swing blocks 212. The two swinging blocks 212 are respectively mounted on bearing seats 214 at the front and rear ends of the straight-edge jaw mounting plate 201 through swinging shafts 213, so that the straight-edge jaw clamping blocks 211 can swing around the swinging shafts 213. The inner ends of the two swinging blocks 212 are connected with a synchronous driving plate 215 which is horizontally arranged. The two straight edge pinching mechanisms correspond to the two synchronous driving plates 215, respectively. The two synchronous drive plates 215 are parallel to each other and to the straight-sided nip block 211. The frame plate 101 is perpendicular to the synchronization driving plate 215. The synchronization driving plate 215 passes through the card hole 102. The synchronization driving plate 215 can be pushed against the upper edge of the card hole 102. When the synchronization driving plate 215 is pushed against the upper edge of the card hole 102, the width of the straight-sided nip gap 222 is maximized. The width of the straight-sided nip gap 222 is the distance between the top surface of the straight-sided nip block 211 and the bottom surface of the straight-sided nip guide plate 220. The maximum width of the straight edge nip gap 222 is no more than 6 millimeters. A horizontal impact plate 232 and a vertically disposed impact cylinder 231 are disposed above the two synchronous drive plates 215. The impact cylinder 231 is mounted on the grill plate 101. The horizontal impact plate 232 is positioned below the impact cylinder 231 and is connected to the piston of the impact cylinder 231 through a horizontal mounting frame, so that the horizontal impact plate 232 can be lifted and lowered by the impact cylinder 231. When the horizontal impact plate 232 is driven by the impact cylinder 231 to push against the synchronous driving plate 215, the two straight-edge clamping blocks 211 of the two straight-edge clamping mechanisms can be driven to swing upwards at the same time. The spring mechanism is used to pull the straight edge jaw 211 down when the horizontal strike plate 232 is not resting on the synchronous drive plate 215. In this embodiment, the spring mechanism includes a spring 216 and a spring mounting bar 103. The spring mounting bar 103 is vertically mounted on the straight-sided nip mounting plate 201 and is located outside of the synchronous drive plate 215. The spring 216 is disposed between the synchronous drive plate 215 and the top end of the spring mounting bar 103. Those skilled in the art will appreciate that the spring mechanism may be provided in a variety of ways, for example, the spring mechanism may be a shaft spring mounted within the swing shaft 213, and the straight edge clamp block 211 may be pulled to swing downward by the shaft spring within the swing shaft 213.
The working principle of this embodiment is shown in fig. 4. In fig. 4, 3901 is a base plate; 3902 is a coaming; 4903 is a bottom plate bending edge; 4904 is a coaming bending edge; 1901 is a right angle support block. Right angle support block 1901 is a component of the liner support mechanism for supporting enclosure 3902 and bottom plate 3901. Initially, both the floor fold 4903 and the coaming fold 4904 are 90 degree folds. When the refrigerator liner opening coaming and the bottom plate are placed on the liner supporting mechanism, the bottom plate 3901 is perpendicular to the coaming 3902. When the roller refrigerator liner double-short-side corner line riveting mechanism of the embodiment works, firstly, the edge part of the bottom plate 3901, the coaming bending edge 4904 and the bottom plate bending edge 4903 are clamped into the straight edge clamping gap 222 of the straight edge clamping mechanism through the movement of the mechanical arm. Since the maximum width of the straight edge nip gap 222 is 6mm less than the width of the floor crimping 4903. Therefore, when the bottom plate bending edge 4903 is caught in the straight edge nip gap 222, the bottom plate bending edge 4903 is further bent. Then, the edge portion of the bottom plate 3901, the coaming bending edge 4904 and the bottom plate bending edge 4903 are riveted into a three-layer edge structure by the swinging movement of the straight edge clamping block 211. And then the straight-edge bending die strip 321 and the straight-edge pressing die strip 311 in the straight-edge pressing plate bending mechanism are respectively moved to the three-layer edge structure and the right-angle supporting block 1901 by the movement of the mechanical arm. Then, the driving cylinder 301 drives the straight-side bending die bar 321 and the straight-side pressing die bar 311 to press down. When the straight edge pressing mold strip 311 presses on the right angle support block 1901 and continues to press down, the spring column mechanism 312 contracts, so that the straight edge pressing mold strip 311 is clamped on the right angle support block 1901, and the straight edge bending mold strip 321 presses the three-layer edge structure, so that the three-layer edge structure is further bent, and a corner four-layer riveting structure is formed. After riveting is finished, firstly, the wheel surface of the side pressing wheel 341 is pressed on the four-layer riveting structure at the corner through movement of the mechanical arm, and then when the double short side corner line riveting mechanism of the refrigerator liner is reset and retracted, the side pressing wheel 341 is pressed on the four-layer riveting structure at the corner for rolling. When the resetting of the double short side corner line riveting mechanism of the refrigerator liner is completed, the pressing and rolling of one round is just completed. For a more detailed description and illustration of the above working principle, see 201711188554.9, for a riveting device for a short side corner line of a refrigerator liner.
