The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0023] Please see Figures 1 to 6The present invention preferably provides the following technical solution: a bending equipment for processing and producing steel structure metal components, comprising: a base plate 111; pre-bending seats symmetrically arranged on the base plate 111 for horizontally placing steel bending elements 311, and the two sets of pre-bending seats forming a U-shaped pre-bending cavity; and a base frame 211 arranged on the pre-bending seats, wherein a pressing forming module is arranged in the middle of the base frame 211, and when the pressing forming module presses down, the steel bending element 311 can complete a first bending in the U-shaped pre-bending cavity; a secondary bending assembly is also symmetrically arranged on the pre-bending seat, and when the pressing forming module continues to press down, the steel bending element 311 can complete a second bending under the action of the secondary bending assembly.

[0024] Combination Figure 1 , 2 As shown in Figures 3 and 4, the pressing forming module and two sets of pre-bending seats are arranged vertically. A U-shaped pre-bending cavity is formed between the two sets of pre-bending seats. The upper surfaces of the two sets are used to horizontally place the steel bending element 311. When the pressing forming module is driven to move downward, the pressing forming module presses the steel bending element 311 into the U-shaped pre-bending cavity for pre-bending. As the pressing forming module continues to move downward, the secondary bending components symmetrically arranged between the two pre-bending seats can perform secondary bending on the pre-bent steel bending element 311, ensuring the bending effect and meeting the conventional bending requirements of the steel bending element 311.

[0025] This application, through the setting of a pre-bending seat and a secondary bending assembly, can sequentially realize the pre-bending and secondary bending processes of the steel bending element 311 during the downward movement of the pressing forming module, overcoming the problem of excessive springback caused by one-time forming, while meeting the conventional bending requirements of the steel bending element 311 and ensuring the bending effect.

[0026] Furthermore, each pre-bending seat includes a base 112 fixed to the upper surface of the substrate 111; the pre-bending grooves opened on opposite sides of the two bases 112 together form a U-shaped pre-bending cavity.

[0027] Combination Figure 1 , 2 As shown in Figures 3 and 4, the bases 112 where the two pre-bending seats are located are arranged opposite each other, and the pre-bending grooves opened on the opposite sides of the two bases 112 together form a U-shaped pre-bending cavity. At the same time, the steel bending element 311 is placed on the upper surface of the two bases 112. Therefore, when the pressing forming module moves down, the pressing forming module can extend into the U-shaped pre-bending cavity and pre-bend the steel bending element 311.

[0028] Furthermore, each secondary bending assembly includes: an arc-shaped groove 113 formed in the base 112 and connected to the pre-bending groove, with a rotatable roller 115 disposed in the arc-shaped groove 113; support rods 114 respectively disposed on both sides of the base 112, with a pin rotatably mounted between the two support rods 114, passing through the roller 115 and fixed to the roller 115; connecting columns 116 respectively disposed on the upper part of the roller 115 and the base 112, with a spring 117 connected between the two connecting columns 116; and a groove disposed on the side of the roller 115 near the pre-bending groove, with a bending pressure member disposed in the groove, so that when the pressing forming module continues to press down, the steel bending element 311 can complete the secondary bending between the two bending pressure members.

[0029] like Figure 1 , 2 As shown in Figures 3, 4, and 6, the arc-shaped groove 113 is connected and communicates with the pre-bending groove where the U-shaped pre-bending cavity is located. The roller body 115 inside the arc-shaped groove 113 has a groove corresponding to the pre-bending groove. At the same time, a spring 117 is connected between the roller body 115 and the connecting column 116 respectively provided on the upper part of the base 112 so as to reset the roller body 115.

[0030] In order to increase the stability of the roller 115, the pin fixed inside the roller 115 is rotatably installed with the support rods 114 respectively set on both sides of the base 112 so that the roller 115 can rotate stably. Therefore, when the two bending pressure pieces set on the opposite sides of the two rollers 115 are pressed down by the pressing forming module to the middle of the steel bending element 311, they can be adaptively deflected to complete the secondary bending operation of the steel bending element 311.

[0031] Furthermore, each bending press includes: a first fixing plate 118 fixed to the upper wall of the groove where the roller body 115 is located, and a first adjusting plate 119 rotatably mounted to the first fixing plate 118 via a rotating shaft provided at the lower part of the first fixing plate 118; first arc-shaped frames 120 are fixed on both sides of the roller body 115 respectively; and a first screw 121 is installed through the first adjusting plate 119, wherein the two ends of the first screw 121 pass through the two first arc-shaped frames 120 respectively and are provided with first nuts 122, which are used to lock the position of the first adjusting plate 119 when the two first nuts 122 are tightened in the direction of each other.

[0032] Combination Figure 6 As shown, the first fixed plate 118 and the first adjusting plate 119 are mounted on opposite ends via a rotating shaft. The first fixed plate 118 is fixed to the upper wall of the groove on the roller body 115. The first adjusting plate 119 moves near the lower wall of the groove and moves inside the first arc-shaped frame 120 set on both sides of the roller body 115 via the first screw 121 on it, so as to adjust the angle of the first adjusting plate 119 relative to the first fixed plate 118, so as to adjust the bending angle of the steel bending element 311.

[0033] Meanwhile, the first nuts 122 respectively set at both ends of the first screw 121 realize the position locking of the first adjusting plate 119.

[0034] Furthermore, when the first fixing plate 118 is reset, it is flush with the upper wall of the pre-bent groove on the base 112.

[0035] Combination Figure 6 As shown, the first fixing plate 118 is embedded in the arc-shaped groove 113 in the initial position. It can also be described that when the first fixing plate 118 is reset, it is flush with the upper wall of the pre-bending groove on the base 112 to maintain the shape of the U-shaped pre-bending cavity and provide a good bending environment for the insertion of the pressing forming module and the bending of the steel bending element 311.

[0036] Furthermore, the pressing molding module includes a cylinder 212 disposed at the top of the base frame 211, a mounting block 213 fixed to the output end of the cylinder 212, and a second fixing plate 214 symmetrically fixed to the bottom of the mounting block 213; the pressing molding module also includes a second adjusting plate 215 rotatably mounted on the opposite sides of the two second fixing plates 214, a second screw 217 horizontally fixed on the second adjusting plate 215, and a second nut 218 threadedly connected to both ends of the second screw 217; each second fixing plate 214 is provided with a second arc frame 216 on both sides, which is used to lock the angle of the second adjusting plate 215 when the two ends of the second screw 217 pass through the two second arc frames 216 and are locked by the second nut 218.

[0037] Combination Figure 3 , 4 As shown in Figure 5, two second fixing plates 214 are fixed to the bottom of the mounting block 213 which is fixed to the output end of the cylinder 212. Two second adjusting plates 215 are rotatably mounted on opposite sides of the two second fixing plates 214. The second screw 217 on each second adjusting plate 215 can pass outward through the two second arc-shaped frames 216 fixed to the second fixing plate 214 and be angle-locked by the second nut 218, thereby realizing the angle adjustment of the second adjusting plate 215 relative to the second fixing plate 214. It is worth noting that the angle adjustment of the second adjusting plate 215 relative to the second fixing plate 214 and the first adjusting plate 119 relative to the first fixing plate 118 should be consistent to improve the bending effect of the steel bending element 311.

[0038] Furthermore, the transverse diameter of the two second fixing plates 214 plus the thickness of the steel bending element 311 should be less than the inner edge of the U-shaped pre-bending cavity, combined with... Figure 5 As shown, this is to ensure the smooth progress of the bending process.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Among these, there are various methods of detachable installation, such as using a combination of plug-in and snap-fit, or using bolt connections, etc.
