DETAILED DESCRIPTION

[0014] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0015] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0016] Example:

[0017] A thick material V-bending die comprises an upper die, a lower die, and a positioning assembly. The upper die comprises an upper support plate 1 and a fixed plate 2 fixedly mounted on the lower surface of the upper support plate 1. A punch 3 for bending the blank is detachably connected to the fixed plate 2. Specifically, the punch 3 is fixedly mounted on the lower surface of the upper support plate 2 via a locking screw 15. The lower die comprises a base plate 4 and a lower pad 5 fixed to the upper surface of the base plate 4. A die 6 is fixedly mounted on the upper surface of the lower pad 5, arranged opposite the die 3. The die 6 and the punch 3 are used to cooperate in forming a V-shaped workpiece 7. The positioning assembly is used to determine the length of the wing of the V-shaped workpiece.

[0018] Specifically, the positioning assembly includes a standard block 8 and a fine-tuning insert A9 and a fine-tuning insert B10 respectively arranged on both sides of the die 6; the standard block 8 includes a plurality of standard blocks with the same height but different widths, and the fine-tuning insert A9 and the fine-tuning insert B10 both include abutting protrusions 11, mounting portions 12 and positioning portions 13, the abutting protrusions 11 are attached to the upper surface of the die 6, the mounting portions 12 are attached to the upper surface of the lower pad 5, and the fine-tuning inserts A9 and the fine-tuning inserts B10 are fixed to the lower pad 5 through the positioning portions 13, specifically, a tightening screw 14 is provided on the positioning portion 13, and the positioning portion 13 is fixed to the lower pad 5 through the tightening screw 14.

[0019] Specifically, during use, the present invention places a blank on the upper surface of the die 6, with the abutting protrusions of the fine-tuning inserts A9 and B10 respectively abutting against the two side walls of the blank. The positions of the fine-tuning inserts A9 and B10 are simultaneously adjusted leftward or rightward according to the bending position of the V-shaped workpiece. After the bending position is adjusted, the fine-tuning inserts A9 and B10 are tightened using the tightening screws 14 to complete the positioning. At this point, blanks can be placed successively on the die 6 for die closing and bending.

[0020] When the length of the two side wing panels of the V-shaped workpiece needs to be adjusted according to the size, one or more standard blocks of different widths are placed against the side wall of the bottom plate 5 so that the outer wall of the standard block or standard block group is flush with the side wall of the positioning portion 13. When the left wing panel of the V-shaped workpiece needs to be increased by a certain length ΔS, while the right wing panel needs to be reduced by a corresponding length ΔS, a standard block with a width of ΔS or a standard block group of multiple standard blocks with a width of ΔS is selected and placed against the side wall of the previous standard block. Loosen the tightening screws 14 on the fine-tuning inserts A9 and B10, first adjust the position of the fine-tuning insert A9 so that the side wall of the positioning portion 13 is flush with the outer wall of the standard block set again, and then use the tightening screws 14 to secure the fine-tuning insert A9. After the fine-tuning insert A9 is secured, place the blank on the surface of the die 6, adjust the position of the fine-tuning insert B10 so that the abutting protrusion 11 of the fine-tuning insert B10 is in close contact with the blank, and finally tighten the fine-tuning insert B10 with the tightening screws 14 to complete the positioning of the new product. After positioning is completed, the blanks can be placed on the die 6 one by one for the new product to be closed and bent.

[0021] In the above embodiment, preferably, the punch 3 includes a plurality of punches with different bending angles. When forming a V-shaped workpiece 7 with different R angles, the forming purpose can be achieved by replacing the punches 3 with different bending angles.

[0022] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
