Description

Technical Field

[0001] The utility model relates to the technical field of equipment for steel structure production, in particular to a pipe bending device used for steel structure production. Background Art

[0002] Steel structure is a structure made of steel materials. Its structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. It is one of the main types of modern building structures. Bending equipment is used in construction projects such as bridges and super high-rise buildings. The purpose is to bend steel structures to adapt to special situations such as corners in the building.

[0003] When using existing pipe bending equipment for steel structure production, the steel structure is generally bent into shape inside the mold cavity through a pipe bending wheel. However, since the bent end of the steel structure is in an infinite position during the bending process, the steel structure is easily offset or tilted due to uneven force, which affects the forming effect. In severe cases, it may even cause the steel structure to be scrapped, which is not conducive to the continued bending of the steel structure. Utility Model Content

[0027] The reinforcement assembly 9 includes a support 914 provided at the bottom of the processing table 1. The support 914 and the axis of the semicircular block 4 are in the same plane. The support 914 is connected to the processing table 1 and the base plate 2 respectively. The outer side of the support 914 is rotatably connected to the first fixed cylinder 91. One side of the first fixed cylinder 91 is fixedly connected to an L-shaped rod 96. The side of the processing table 1 away from the through groove 11 is provided with an arc surface 913. One side of the L-shaped rod 96 is fixedly connected to a second guide block 911. One side of the arc surface 913 is provided with a second guide groove 912 corresponding to the second guide block 911. Figure 5 As shown, the second guide block 911 and the second guide groove 912 cooperate with the first fixed cylinder 91 to limit the L-shaped rod 96 from both ends, so that the displacement of the reinforcement component 9 is smoother and more stable; the second guide block 911 is located inside the second guide groove 912, and the end of the L-shaped rod 96 away from the first fixed cylinder 91 is fixedly connected to the second fixed cylinder 97, and an arc plate 98 is provided inside the second fixed cylinder 97. Guide rods 910 are vertically installed at both ends of the arc plate 98, and one end of the guide rod 910 passes through the outside of the second fixed cylinder 97.

The bottom end of the pillar 914 is fixedly connected to the driven gear 95. The driven gear 95 is meshed with the second driving gear 94. By setting a first oil cylinder 99, the arc plate 98 can be driven to approach one side of the steel structure, thereby achieving the fixation of the end of the steel structure. The second motor 93 and the second driving gear 94 are then used to drive the second fixed cylinder 97 to move synchronously with the bending pipe assembly 8. In this way, the steel structure is bent by the bending pipe assembly 8 while being limited by the reinforcing assembly 9, the clamping assembly 13 and the limiting assembly 6 from both ends and the outside, so that the steel structure is not easily offset and tilted, which is more conducive to the stable performance of the bending work.

[0028] Working principle: First, the staff uses the clamping component 13 to position and fix the steel structure from one end. Then, driven by the driving component 10, the steel structure passes through the limiting component 6, the forming cavity 5, the bending component 8, and the reinforcing component 9 in turn. In this way, the bending position of the steel structure can be determined quickly and conveniently. After the positioning of the steel structure is completed, the bending component 8 is used to bend the steel structure along the forming cavity 5. During this period, the reinforcing component 9 changes synchronously with the position change of the bending component 8 from the bent end of the steel structure. At the same time, it cooperates with the clamping component 13 and the limiting component 6 to limit it from both ends and the outside, so that the steel structure is not easy to shift and tilt, which is more conducive to the stable bending work.
