[0020] A sheet metal parts bending die, including

[0021] The upper mold assembly includes an upper mold base 1, an upper template 2 fixedly connected to the bottom of the upper mold base 1, a first upper mold pressing block 3 and a second upper mold pressing block 4 fixedly connected to the bottom of the upper template 2, a first V-shaped protrusion 31 provided in the middle of the first upper mold pressing block 3, and a second downwardly extending protrusion 41 provided on the side of the second upper mold pressing block 4 away from the first upper mold pressing block 3, and a first inclined surface 42 provided on the inner side of the second protrusion 41.

[0022] The lower mold assembly includes a lower mold base 5, a lower mold pressing block 6 is fixedly connected to the top of the lower mold base 5, the top of the lower mold pressing block 6 is provided with a V-shaped groove 61 that matches the first protrusion 31, and a second inclined surface 62 that matches the first inclined surface 42 is provided on one side of the top of the lower mold pressing block 6.

[0023] This invention, by setting a first upper die pressure block and a second upper die pressure block, allows for precise V-shaped bending of sheet metal parts by matching the V-shaped first protrusion 31 on the first upper die pressure block with the V-shaped groove 61 on the lower die pressure block 6. Simultaneously, the first inclined surface 42 on the second upper die pressure block 4 matches the second inclined surface 62 on the lower die pressure block 6, enabling downward bending of the side of the sheet metal parts. This achieves multi-directional bending operations and ensures bending accuracy. Through the synergistic effect between the various pressure blocks, the die can complete the bending of sheet metal parts in one operation, improving processing efficiency, reducing processes, and achieving precise and efficient bending of sheet metal parts. It is suitable for mass production of high-precision sheet metal parts.

[0024] Furthermore, in another embodiment, the upper mold assembly is also provided with a pressing mechanism, the pressing mechanism including pressing rods 7 located on both sides of the first protrusion 31, the bottom of the pressing rods 7 penetrating the lower surface of the first upper mold pressing block 3; a spring 8 is fixedly connected to the top of the pressing rods 7, the top of the spring 8 passing through the first upper mold pressing block 3 and the upper template 2 in sequence and abutting against each other with a spring nut 9, the spring nut 9 being connected to the upper mold base 1.

[0025] By setting up a clamping mechanism, the clamping rod 7 of the clamping mechanism is located on both sides of the first protrusion 31. Under the action of the spring 9 and the spring nut 9, the upper die assembly can apply downward pressure to the sheet metal part through the bottom of the clamping rod 7 when pressing down, thereby ensuring that the sheet metal part is stably clamped during the bending process, preventing it from shifting or warping, thereby improving the bending quality.

[0026] Furthermore, in another embodiment, one side of the first upper mold block 3 is fixedly connected to the second upper mold block 4 by a fixing bolt 10.

[0027] By setting the fixing bolts 10, gaps are prevented between the first upper die pressing block 3 and the second upper die pressing block 4, which would affect the bending quality of the sheet metal parts and improve the bending accuracy of the sheet metal parts.

[0028] Furthermore, in another embodiment, the lower mold pressing block 6 is fixedly connected to an upwardly extending limiting block 63 at one end away from the second inclined surface 62 and on both sides of the V-groove 61.

[0029] By setting a limit stop 63, the position of the sheet metal part can be limited when it is placed on the lower die pressing block 63, so as to prevent the sheet metal part from being misaligned during the bending process and thus improve the positioning accuracy of the sheet metal part bending.

[0030] Furthermore, in another embodiment, guide rods 11 are fixedly connected to the four corners of the lower mold base 5, and guide sleeves 12 that cooperate with the guide rods 11 are fixedly connected to the four corners of the upper mold base 1.

[0031] The guide rods 11 at the four corners of the lower mold base 5 are connected to the guide sleeves 23 at the four corners of the upper mold base 1, which play a precise guiding role during the up and down movement of the mold, ensuring the accuracy of the position of the upper mold assembly and the lower mold assembly when the mold is closed.
