Referring to fig. 2 and 3, the lower die 11 includes: base 100, gasket 200 and a plurality of pressure-bearing monomers 300.
Referring to fig. 1 and 5, the pressure-bearing units 300 are slidably disposed on the base 100, the pressure-bearing units 300 are on the same straight line, a pressure-bearing groove 310 is formed on a side of the pressure-bearing unit 300 away from the base 100, and the upper die 12 is disposed towards the pressure-bearing groove 310; the pressure-bearing groove 310 is a bending forming position of the plate 30 to be bent, the cross section of the pressure-bearing groove 310 is V-shaped, and the included angle between two adjacent groove surfaces in the pressure-bearing groove 310 is the target bending angle of the plate 30 to be bent.
Referring to fig. 4 and 5, the gasket 200 is disposed on a side of the pressure-bearing unit 300 close to the upper die 11, and there is no connection between the gasket 200 and the pressure-bearing unit 300, and the gasket 200 includes an arc transition portion 210, a bending portion 220, and limiting portions 230 disposed on two sides of the bending portion 220, wherein the limiting portions 230 are attached to the pressure-bearing unit 300, the positions of the limiting portions 230 are non-bending portions, which are attached to an upper end surface (i.e., a side close to the upper die 11) of the pressure-bearing unit 300, and two sides of the transition portion 210 are respectively provided with a limiting portion 230 to provide a gripping portion for an operator to pick up the gasket 200.
The bending angle of the bending part 220 is consistent with the included angle between two adjacent groove surfaces in the pressure-bearing groove 310, after the gasket 200 is placed on the pressure-bearing single body 300, the bending part 220 is attached to the groove wall of the pressure-bearing groove 310, the arc transition part 210 is positioned at the bottommost end of the bending part 220 (as shown in fig. 5), and the arc transition part 210 is arranged towards the groove bottom of the pressure-bearing groove 310. The arc transition portion 210 has an arc-shaped cross section, and contacts with the bending portion of the plate material when bending, so as to avoid forming a crease at the bending position after bending the plate material.
In the bending process, the gasket 200 is in contact with the plate 30 to be bent, specifically, the gasket 200 is located between the pressure-bearing single body 300 and the plate 30 to be bent, when the upper die 12 is close to the lower die 11, the plate 30 to be bent is pressed on the bending part 220 of the gasket 200, when the bending action is completed, the plate 30 to be bent is attached to the bending part 220 and the arc transition part 210 of the gasket 200, the gasket 200 is in non-fixed connection with the pressure-bearing single body 300, and the gasket 200 can be directly taken down from the pressure-bearing single body 300, so that the replacement is convenient. The length of the gasket 200 is identical to the length of the plate 30 to be bent.
In the bending process, the gasket 200 is used as a part directly contacted with the plate 30 to be bent, the bearing monomers provide support and guide, the gasket 200 is used as a wearing part in the bending process, after the die is worn, the gasket 200 is only needed to be replaced, and the gasket 200 has small thickness, light weight and low processing difficulty, saves materials and can save the manufacturing cost of the lower die.
It should be noted that, the plurality of pressure-bearing monomers 300 are all attached to the base 100, that is, the plurality of pressure-bearing monomers 300 are on the same straight line, and the number of pressure-bearing monomers 300 can be increased or decreased according to the length of the plate 30 to be bent, for example, when the length of the plate 30 to be bent is smaller than that of a single pressure-bearing monomer 300, the bending operation can be completed only by the single pressure-bearing monomer 300, and when the length of the plate 30 to be bent is greater than that of the pressure-bearing monomer 300, the rest pressure-bearing monomers 300 on the base 100 are spliced together, so that the total length of the spliced pressure-bearing monomers 300 is greater than (or equal to) that of the plate 30 to be bent. Preferably, both ends of the pressure-bearing monomer 300 are provided with magnetic attraction sheets. When two adjacent pressure-bearing monomers 300 are close to each other, the two adjacent pressure-bearing monomers 300 can be adsorbed together through the magnetic field generated by the magnetic attraction piece, so that the separation of the two adjacent pressure-bearing monomers 300 in the bending process is avoided. Therefore, when another sheet metal part needs to be processed, the bending angle of the sheet metal part is unchanged, and only the lengths of the plates are different, the original gasket 200 is only required to be taken out, the gasket 200 with the corresponding length is placed on the pressure-bearing single body 300, the whole lower die 11 is not required to be replaced, and the manufacturing cost of the jig is saved.
Because the gasket 200 is a thin plate, the gasket 200 with the same angle of the bending part 220 can be directly stacked together (as shown in fig. 6), which is beneficial to saving the storage space of the jig and improving the space utilization rate.
In summary, the pressure-bearing groove 310 on the pressure-bearing monomer 300 is matched with the bending part 220 of the gasket 200 to be used as a forming cavity for bending the sheet metal parts, and when the plurality of pressure-bearing monomers 300 on the base 100 are required to process sheet metal parts with the same angle and different lengths, only the gasket 200 is required to be replaced, the lower die 11 with the corresponding length is not required to be additionally manufactured, the manufacturing cost of the jig can be saved, the gasket 200 is thin and light, the storage is convenient, and the storage space of the jig is saved.
Referring to fig. 5, in an embodiment, a space is provided between the arc transition portion 210 and the bottom of the pressure-bearing groove 310. After the plate is bent, the portion of the plate that is bent and deformed is in an arc shape, and a space is provided between the arc transition portion 210 and the bottom of the pressure-bearing groove 310, that is, the bottom of the pressure-bearing groove 310 does not need to be processed with a rounded corner matched with the arc transition portion 210, so that the portion of the pressure-bearing single body 300 that needs to be processed is reduced, and the processing cost of the pressure-bearing single body 300 is reduced.
