[0023] like Figure 1-4 As shown, this application discloses a progressive die for bending products, including an upper die 10 and a lower die 20. The upper die 10 includes an upper die base 11, an upper backing plate 12, and a stripper plate 13 arranged sequentially from top to bottom. The upper die 10 is provided with a punch 14, a first bending head 15, a second bending head 16, a shaping head 17, and a cutting head 18 along the feeding direction. The punch 14, the first bending head 15, the second bending head 16, the shaping head 17, and the cutting head 18 are all mounted on the upper backing plate 12 and can pass through the stripper plate 13 and extend out of the stripper plate 13. A plurality of bolts 111 are movably inserted on the upper die base 11. The plurality of bolts 111 pass through the upper backing plate 12 and are connected to the stripper plate 13. The plurality of bolts 111 between the upper backing plate 12 and the stripper plate 13 are all fitted with springs 112. The lower die 20 includes a lower die base 21, a lower die template 22, and a lower support plate 23 arranged sequentially from top to bottom. The lower die 20 is provided with a punch hole 24 that cooperates with the punch 14, a first bending seat 25 that cooperates with the first bending head 15, a second bending seat 26 that cooperates with the second bending head 16, a shaping seat 27 that cooperates with the shaping head 17, and a cutting hole 28 that cooperates with the cutting head 18. During operation, the feeding mechanism feeds the material into the lower die from the feeding port, and the upper die moves downward. The cooperation between the punch and the punch hole, the cooperation between the first bending head and the first bending seat, the cooperation between the second bending head and the second bending seat, the cooperation between the shaping head and the shaping seat, and the cooperation between the cutting head and the cutting hole respectively complete the punching, first bending, second bending, shaping, and cutting operations, thereby realizing the completion of multiple specific processes in one stamping. This not only has low cost but also high efficiency and is suitable for mass production.

[0024] Specifically, two limiting blocks that cooperate with the stripper plate 13 are arranged side by side on the lower mold base 21 to limit the stroke of the upper mold.

[0025] Specifically, the lower mold base 21 is provided with the first bending seat 25, the first bending seat 25 has a first force-bearing inclined surface 251 arranged along the length direction, and the first bending head 15 has a first driving inclined surface 151 that cooperates with the first force-bearing inclined surface 251. When the upper mold moves downward, the first driving inclined surface of the first bending head cooperates with the first force-bearing inclined surface of the first bending seat to bend the horizontal part of the L-shaped support formed on one side of the material body in the previous process upward.

[0026] Specifically, the lower mold base 21 includes a second bending seat 26 disposed on the lower template 22 corresponding to the second bending head 16.

A second force-bearing inclined surface 261 is formed on one side of the second bending seat 26 along the width direction. The second bending head 16 has a second driving inclined surface 161 that cooperates with the second force-bearing inclined surface 261. When the upper mold moves downward, the second driving inclined surface of the second bending head cooperates with the second force-bearing inclined surface of the second bending seat to bend the L-shaped support vertically downward.

[0027] Specifically, the lower mold base 21 further includes a shaping seat 27 disposed on the lower template 22 corresponding to the shaping head 17 and the cutting head 18. One end of the shaping seat 27 forms a first force-bearing shaping inclined surface 271 disposed along the length direction and a second force-bearing shaping inclined surface 272 disposed along the width direction. The shaping head 17 has a first driving shaping inclined surface 171 that cooperates with the first force-bearing shaping inclined surface 271 and a second driving shaping inclined surface 272 that cooperates with the second force-bearing shaping inclined surface 271. The second driving shaping inclined surface 172 is matched with the shaping base 27; the cutting hole 28 is also provided on the shaping base 27. Through the above structural design, the upper mold moves downward, and the first driving shaping inclined surface and the second driving shaping inclined surface of the shaping head are matched with the first force shaping inclined surface and the second force shaping inclined surface, respectively, to shape the L-shaped support foot, so as to correct the shape, size or surface condition of the L-shaped support foot of the material and improve the forming accuracy and consistency; the cutting head 18 is matched with the cutting hole 28 to complete the cutting of the shaped material.

[0028] Specifically, a material collection box 29 is provided on the lower support plate 23 near the shaping seat 27, and a sliding seat is provided above the lower template near the shaping seat. The cut material slides into the material collection box along the sliding seat.

[0029] Specifically, the upper mold base 11 is provided with guide posts 113 at each of its four corners, and the lower mold base 21 is provided with guide sleeves 211 that cooperate with each of the guide posts 113. The upper mold base 11 is provided with several protruding rings 1131 that abut against the guide posts 113 to limit the upper limiting pieces 1132 of the guide posts 113. Each upper limiting piece 1132 is installed on the upper mold base 11 by screws. The lower mold base 21 is provided with several annular grooves 2111 that insert into the guide sleeves 211 to limit the lower limiting pieces 2112 of the guide sleeves 211. Each lower limiting piece 2112 is installed on the lower mold base 21 by screws. The upper and lower limiting pieces limit the guide posts and guide sleeves respectively, preventing axial movement of the guide posts and loosening and material loss of the guide sleeves, thus ensuring production safety and continuity.

[0030] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, high efficiency, and low cost.
