Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the round corner riveting mechanism for the bottom plate of the refrigerator liner comprises a horizontal round corner flanging mechanism, a round corner pressing plate flanging mechanism and a round corner riveting rack. The horizontal fillet flanging mechanism and the fillet pressing plate flanging mechanism are arranged on the fillet riveting frame. The horizontal fillet flanging mechanism is positioned below the fillet pressing plate flanging mechanism. The fillet riveting rack comprises two rack side plates 421, a rack top plate 422, a rack back plate 423 and a rack bottom plate 424. The housing floor 424 is horizontally disposed. Two rack side plates 421 are vertically disposed on both sides of the rack bottom plate 424. The frame top plate 422 is provided on top of two frame side plates 421. The frame back plate 423 is disposed between the two frame side plates 421 and perpendicular to the two frame side plates 421.
The horizontal fillet hemming mechanism includes a fillet translating frame 431, a horizontal fillet hemming die bar 432, and a fillet horizontal cylinder 433. The rounded translating carriage 431 is mounted to the frame base 424 of the rounded riveting frame by means of a slide 435 and a slide 434 and is capable of horizontal movement along the slide 434. A horizontal fillet hemming die strip 432 is installed at the front end of the fillet translating frame 431. The round horizontal cylinder 433 is mounted on the frame back plate 423 of the round riveting frame, and the piston of the round horizontal cylinder is connected with the rear end of the round translation frame 431. The front end face of the horizontal fillet flanging die strip 432 is provided with a die groove with a circular arc horizontal section.
The fillet platen hemming mechanism comprises a fillet vertical cylinder 441, a fillet die bar lifting frame 442, a fillet platen 443 and a vertical fillet hemming die bar 444. The round angle die bar lifting frame 442 is mounted below the frame top plate 422 of the round angle riveting frame through a guide post and guide sleeve mechanism 4421. A rounded vertical cylinder 441 is mounted above the frame top plate 422 with its piston connected to a rounded die bar lifter 442. The radius presser 443 is mounted below the radius bar frame 442 by a spring post mechanism 4431. A vertical fillet hemming die strip 444 is fixed under the fillet die strip lifter 442. The vertical fillet flanging die strip 444 is a block-shaped body, and a die groove with a circular arc horizontal section is arranged on the front end face. A clamping protrusion with a circular arc horizontal section is arranged at the rear of the round angle pressing plate 443. The corner presser piece 443 is engaged by engaging projections in a die groove on the front end surface of the vertical corner crimping die 444, and is movable in the vertical direction along the die groove with respect to the vertical corner crimping die 444.
The working principle of the embodiment is shown in fig. 3, 4 and 5. In fig. 3, 4 and 5, 3901 is a bottom plate, and a generally Z-shaped bottom plate may also be a flat bottom plate, 4903 is a bottom plate fillet bending edge, 3902 is a coaming, that is, a large and small U-shaped coaming or a port-shaped coaming, 4904 is a coaming fillet bending edge, and 1901 is an arc angle supporting block on the liner supporting mechanism. The bottom plate fillet bent edge 4903 and the coaming fillet bent edge 4904 are both 90-degree bends at the fillet. Bottom plate 3901 is perpendicular to shroud 3902. When the refrigerator liner is provided with the liner supporting mechanism, the liner is provided with the liner-opening coaming and the bottom plate, as shown in figure 3. After the bottom plate fillet riveting mechanism of the refrigerator liner moves to the bottom plate fillet, the riveting process is as follows: first, the round vertical cylinder 441 drives the round bar lifter 442 to press down, and when the round bar presser piece 443 is pressed against the round bar support block 1901, the round bar lifter 442 stops descending. At this time, the bottom surface of the vertical round-corner crimping die 444 is flush with the bottom surface of the round-corner crimping die 443. Then, the horizontal fillet cylinder 433 drives the horizontal fillet folding die strip 432 to press forward so that the bottom plate fillet folding edge 4903 is folded inward, so that the edge portion of the bottom plate 3901, the coaming fillet folding edge 4904, and the bottom plate fillet folding edge 4903 are overlapped to form a three-layer edge structure 4905 as shown in fig. 4. Thereafter, the rounded horizontal cylinder 433 drives the horizontal rounded hemming die strip 432 to retract to the vertical rounded hemming die strip 444. Then, the round vertical cylinder 441 continues to drive the round bar lifting frame 442 to press down, at this time, the round bar pressing plate 443 presses on the round bar supporting block 1901, and the vertical round bar folding die 444 continues to press down, so as to bend the three-layer edge structure 4905 downward to form a corner four-layer riveting structure 4906 as shown in fig. 5, and complete riveting.
