[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model discloses a bridge frame horizontal bending processing and forming device, including a lower die table 1, two upper dies and a positioning device 3, the top of the lower die table 1 is provided with a bending punching groove 11, the interior of the bending punching groove 11 is provided with a storage groove 12, the interior of the storage groove 12 is provided with a plurality of lower die size adjustment plates 13, and the two ends of the lower die size adjustment plates 13 are jointly provided with a lower die driving frame 14.

[0025] The upper die 2 is located directly above the curved punching groove 11, and a receiving groove 21 is provided at the bottom of the upper die 2. The receiving groove 21 is provided with upper die 2 size adjustment plates whose number is the same as the lower die size adjustment plates 13, and upper die 2 drive frames are provided at both ends of the upper die 2 size adjustment plates.

[0026] Specifically, the shapes of the two upper dies match the shape of the curved punching groove 11 .

[0027] Specifically, the positioning device 3 includes a positioning hole 31, a baffle 32 and a mounting cavity 33. A plurality of positioning holes 31 are provided on the adjacent two sides of the lower die table 1 and the two sides of the upper die table 2. At least one baffle 32 is provided on the top of the lower die driving frame 14 and the upper die 2 driving frame. At least one mounting cavity 33 is provided inside the lower die driving frame 14 and the upper die 2 driving frame. A positioning rod 34 is movably provided inside the mounting cavity 33 through a spring 36. One end of the positioning rod 34 is inserted into one of the positioning The other end extends to the inside of one of the baffles 32 and is provided with a groove 35. The storage and rising of the lower die driving frame 14 are locked by the positioning rod 34. When moving the lower die driving frame 14, the user pinches the baffle 32 and pulls the positioning rod 34 out of the positioning hole 31 through the groove 35, and the lower die size adjustment plate 13 can be moved by the lower die driving frame 14. After the lower die driving frame 14 is in place, the groove 35 is released, so that the positioning rod 34 is inserted into the inside of the positioning hole 31 on one side thereof to achieve locking. Figure 1 and Figure 3The principles of the upper die 2 driving frame and the lower die driving frame 14 are roughly the same, except that when the lower die size adjustment plate 13 rises one, the upper die 2 size adjustment plate needs to move the upper die 2 size adjustment plate corresponding to the rising lower die size adjustment plate 13 to the inside of the storage groove 21 for storage. This design method can adapt to different sizes of bridge horizontal bends for stamping processing, and the size adjustment process is simple and fast, ensuring the processing efficiency.

When the user adjusts the lower die size adjustment plate 13, the uppermost lower die driving frame 14 is lifted first, and the uppermost lower die driving frame 14 drives the lower die size adjustment plate 13 to rise, so that the top of the lower die size adjustment plate 13 is kept at the same level as the top of the lower die table 1, and at the same time, the top of the uppermost lower die driving frame 14 abuts against the limit block 15, indicating that the lower die driving frame 14 has risen into place, and when adjusting the remaining two lower die size adjustment plates 13, the second and third lower die driving frames 14 are lifted in turn, and the second lower die driving frame 14 rises and abuts against the uppermost lower die driving frame 14, indicating that it has risen into place, and the third lower die driving frame 14 rises and abuts against the second lower die driving frame 14, indicating that it has risen into place.

[0029] Specifically, it also includes a mold bracket 4, the lower mold table 1 is fixedly arranged on the inner bottom of the mold bracket 4, and a stamping cylinder 41 is arranged on the top of the mold bracket 4. The output end of the stamping cylinder 41 is connected to the top of the upper mold 2. At least two stabilizing rods 42 are movably penetrated on the top of the mold bracket 4, and the bottom end of the stabilizing rod 42 is connected to the top of the upper mold 2. The bridge frame material to be stamped and bent is placed on the lower mold table 1, and the stamping cylinder 41 is started to drive the upper mold 2 to descend. The upper mold 2 descends and presses the bridge frame material into the inside of the bend stamping groove 11 to realize the forming processing of the horizontal bend of the bridge frame. The setting of the stabilizing rod 42 ensures the stability of the upper mold 2 during the lifting process.

[0030] In summary, the bridge frame horizontal bend processing and forming device can perform stamping and forming processing on bridge frame horizontal bends of different sizes through multiple lower die size adjustment plates 13 and upper die 2 size adjustment plates, and the adjustment process of the lower die size adjustment plates 13 and the upper die 2 size adjustment plates is simple and quick. After adjustment, they are locked by the positioning device 3, which ensures the stability of the lower die size adjustment plates 13 and the upper die 2 size adjustment plates after adjustment. It has high versatility and greatly reduces expenditure costs.
