Description

Technical Field

[0001] This utility model relates to the field of mechanical boom processing technology, and in particular to a mechanical boom bending plate processing device. Background Technology

[0002] Mechanical booms are key load-bearing components in engineering machinery such as firefighting machines, cranes, aerial work platforms, mechanical engineering equipment, hydraulic systems, and marine equipment. Made of high-strength steel, they come in various structural forms, including telescopic and folding booms, and their working range is adjusted via a luffing mechanism. According to the national standard GB / T 6974.4-2016, their core function is to support loads and expand the equipment's working range. Modern booms integrate intelligent technologies such as CAN bus control and synchronous telescopic movement, and are widely used in port machinery, wind power installation, and other fields. my country has established a comprehensive standard system covering the entire process of design, manufacturing, and testing, involving specifications for load calculation, safe operation, and other requirements.

[0003] The production process of the robotic arm requires the use of bent sheet metal. This bent sheet metal has a symmetrical structure, including a first inclined segment, a first arc segment, a horizontal straight segment, a second arc segment, and a second inclined segment arranged in sequence. The closer to the horizontal straight segment, the larger the distance between the first and second inclined segments. Due to the large area of ​​the sheet metal, it is difficult to directly bend it in one go. It is necessary to configure additional inclined processing equipment to achieve the inclined processing of the first and second inclined segments. The processing operation is complicated, time-consuming, and labor-intensive. Moreover, the bending of multiple segments must be completed simultaneously in one bending process. The contact area between the mold and the sheet metal is large, the friction is increased, the mold wear is accelerated, and the mold needs to be replaced frequently, resulting in high production costs.

[0030] The edge bending mold 6 includes a bending template block 61 and a connecting block 62, and a V-shaped groove matching the bottom of the bending body is provided at the top center of the bending template block 61.

[0031] The connecting block 62 is positioned within the rectangular receiving groove, and a bending template block 61 is fixed to the top center of the connecting block 62.

[0032] A limiting block 63 is also provided on one side of the edge bending mold 6 on the fixing block 3.

[0033] The limiting block 63 includes a block with a right-angled trapezoidal structure block cut off on the side of the top of the block near the edge bending mold 6, so that the side of the block near the edge bending mold 6 forms an upper horizontal surface, an inclined surface 631, and a middle horizontal surface 632, and the middle horizontal surface 632 is lower than the top surface of the bending template block 61, and an accommodating area 633 is formed between the inclined surface 631, the middle horizontal surface 632, and the bending template block 61, which accommodates and limits the plate material.

[0034] The limiting block 63 has a snap-fit ​​groove on one side near the edge of the bending mold 6, and the side of the bending template block 61 has a corresponding snap-fit ​​protrusion. The limiting block 63 can be detached and installed through the snap-fit ​​groove and the snap-fit ​​protrusion.

[0035] The central flattening die 7 includes a flattening body 71 and a connecting column 72. The top of the connecting column 72 is bolted to the die mounting block 4, and its bottom is connected to the flattening body 71. The flattening body 71 is also a symmetrical structure.

[0036] The middle flattening mold 8 includes a flattening block body 81.

[0039] The working principle of this patent: The V-shaped sheet 1 has a first straight segment 11 and a second straight segment 12. The edge bending die 5 and the edge bending support die 6 are respectively installed on the die mounting block 4 and the fixing block 3. Then, the first straight segment 11 of the V-shaped sheet 1 is placed horizontally on the edge bending support die 6, while the second straight segment 12 is pressed against the top corner of the fixing block 3. At this time, the distance between the end of the first straight segment 11 closest to the second straight segment 12 and the perpendicular bisector of the V-groove of the bending template block 61 is L1. The vertical axis of the die mounting block 4 is as follows... Figure 1 As shown, the edge bending die 5 is driven downward by a hydraulic cylinder to perform a V-shaped bend to form the first sheet material. The first straight segment 11 of the V-shaped sheet material 1 is then bent to form the third straight segment 13 and the fourth straight segment 14, and the third straight segment 13 is positioned away from the second straight segment 12. Figure 2 As shown.

[0040] Then, the first sheet material is removed from the V-groove of the edge bending die 5, and its second straight segment 12 is placed horizontally on the edge bending support die 6. Simultaneously, the bending area of ​​the V-shaped segment formed by the first straight segment 11 is within the receiving area 633, and the slope of the inclined surface 631 is consistent with that of the third straight segment 13. At this time, the distance between the end of the second straight segment 12 closest to the first straight segment 11 and the perpendicular bisector of the V-groove of the bending template block 61 is L2, and L1 = L2. Figure 3 As shown, the edge bending die 5 is driven downward by a hydraulic cylinder to perform a secondary V-bending to form a W-shaped second sheet material. The second straight segment 12 of this V-shaped sheet material 1 is then bent to form a fifth straight segment 15 and a sixth straight segment 16, with the sixth straight segment 16 positioned away from the third straight segment 13. Figure 4 As shown.

[0041] Next, remove the second sheet material, and install the central flattening die 7 and the central flattening support die 8 onto the die mounting block 4 and the fixing block 3 respectively. Then, place the second sheet material into the shrinkage groove of the mold groove, as shown. Figure 5 As shown, the hydraulic cylinder drives the central flattening die 7 downwards for flattening, causing the fourth straight segment 14 and the fifth straight segment 15 to form a horizontal straight segment 93. Simultaneously, the third straight segment 13 and the sixth straight segment 16 shrink through the upper shrinkage groove 83 to form the first inclined segment 91 and the second inclined segment 95. At this point, the bent sheet metal is formed, as shown... Figure 6 As shown.
