Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a straightening device for steel structure processing. Background Technology

[0002] Steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. During the processing of steel structures, product defects may occur due to improper flame straightening temperature. However, conventional straightening devices are difficult to straighten different positions of steel structures.

[0003] Existing patent CN220942656U describes a tooling for straightening steel structures. By setting multiple straightening mechanisms, it can simultaneously straighten multiple positions of the steel structure, greatly improving work efficiency. Since the straightening mechanisms are movable, they are easier to adjust to different straightening positions of the steel structure. Multiple corresponding straightening mechanisms can be adjusted to the straightening position, effectively preventing misalignment at the straightening connection and improving the straightening effect. The overall operation is simple and highly practical. Because the cross-section of the pressure plate is L-shaped, it can prevent displacement during the straightening of the steel structure, improving the stability of use.

[0004] However, when using a steel structure straightening tool with an existing patent, the top block used to straighten the steel structure in the device has a small force-bearing area. When the steel structure is squeezed, it is easy to cause excessive deformation of the steel structure, resulting in improper straightening. Utility Model Content

[0005] The purpose of this utility model is to provide a straightening device for steel structure processing, which solves the problem that the top block used to straighten the steel structure in the aforementioned device has a small force-bearing area, which easily leads to excessive deformation of the steel structure when it is squeezed, resulting in improper straightening.

[0006] To achieve the above objectives, this utility model provides a straightening device for steel structure processing, including a straightening table and a support frame. The support frame is fixedly installed on the straightening table. The device also includes a pressing device, which includes a sliding frame, a mounting frame, a pressure roller, a sliding assembly, and a limiting assembly. The sliding frame is slidably installed on the straightening table via the sliding assembly. An electric push rod is provided on the sliding frame. The mounting frame is fixedly installed on the output end of the electric push rod. The pressure roller is rotatably installed on the mounting frame. The limiting assembly is disposed on the straightening table.

[0007] The limiting assembly includes a limiting frame, a positioning frame, a push rod, and a reset component. The limiting frame is slidably mounted on the correction table; the positioning frame is fixedly mounted on the correction table and close to the limiting frame; the push rod is slidably mounted on the positioning frame and contacts the limiting frame; and the reset component is disposed on the correction table.

[0008] The reset component includes a guide rod and a reset spring. The guide rod is fixedly installed on the correction table. The reset spring is sleeved on the guide rod and fixedly connected to the limiting frame.

[0009] The sliding assembly includes a sliding block and a rotating component. The correction table is provided with a sliding groove. The sliding block is slidably mounted on the correction table via the rotating component and is located within the sliding groove.

[0010] The rotating component includes a rotating lead screw and a mounting plate, with the mounting plate fixedly installed on the straightening table; the rotating lead screw is rotatably installed on the mounting plate and threaded through the sliding block.

[0011] This utility model discloses a straightening device for steel structure processing. In use, the steel structure is placed on the straightening table with one end positioned below the limiting frame. Then, a cylinder pushes a push rod downwards along the positioning frame. The movement of the push rod pushes the limiting frame downwards, fixing the steel structure on the straightening table. Next, the electric push rod is activated, causing the pressure roller on the mounting frame to abut against the surface of the steel structure. Simultaneously, a motor drives a rotating lead screw, causing a sliding block to move within a groove. The movement of the sliding block causes the sliding frame to move synchronously, indirectly causing the pressure roller to roll on the surface of the steel structure, effectively straightening any bent parts. The rolling of the pressure roller on the steel structure surface compresses the surface, preventing excessive deformation during straightening. Attached Figure Description

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The embodiment of this application is as follows:

[0018] Please see Figure 1-2 , Figure 1 This is a schematic diagram of the overall structure of a straightening device for steel structure processing according to this utility model. Figure 2 This is a schematic diagram of the limiting component of this utility model.

[0019] This utility model provides a straightening device for steel structure processing: it includes a straightening table 101 and a support frame 102, and also includes a pressing device. The pressing device includes a sliding frame 103, a mounting frame 104, a pressure roller 105, a sliding component, and a limiting component. The limiting component includes a limiting frame 107, a positioning frame 108, a push rod 109, and a reset component. The reset component includes a guide rod 110 and a reset spring 111. The sliding component includes a sliding block 112 and a rotating component. The rotating component includes a rotating lead screw 114 and a mounting plate 115. The above solution solves the problem that the top block used to straighten the steel structure in the aforementioned device has a small force-bearing area, which easily leads to excessive deformation of the steel structure when it is squeezed, resulting in improper straightening. The aforementioned solution can be used in the scenario of steel structure straightening.

[0020] In this embodiment, the pressure roller 105 rolls on the surface of the steel structure to squeeze the surface of the steel structure, thus avoiding excessive deformation of the steel structure during the straightening process.

[0021] The sliding frame 103 is slidably mounted on the straightening table 101 via the sliding assembly. An electric push rod 106 is mounted on the sliding frame 103. A mounting frame 104 is fixedly mounted on the output end of the electric push rod 106. A pressure roller 105 is rotatably mounted on the mounting frame 104. A limiting assembly is disposed on the straightening table 101. The sliding frame 103 has an inverted U-shaped structure, and the mounting frame 104 also has an inverted U-shaped structure. The electric push rod 106 is fixed to the sliding frame 103 by screws, and the pressure roller 105 is also fixed to the sliding frame 103 by screws. The axis of the electric push rod 106 is perpendicular. The sliding assembly can drive the sliding frame 103 to slide. The limiting assembly can fix the steel structure. In use, the steel structure is fixed on the surface of the correction table by the limiting assembly. The electric push rod 106 pushes the mounting frame 104, so that the pressure roller 105 abuts against the surface of the steel structure. Driven by the sliding assembly, the sliding frame 103 drives the pressure roller 105 to roll on the surface of the steel structure, thereby effectively correcting the bent parts of the steel structure and avoiding excessive deformation of the steel structure during correction.

[0022] Secondly, the limiting frame 107 is slidably mounted on the straightening table 101; the positioning frame 108 is fixedly mounted on the straightening table 101 and close to the limiting frame 107; the push rod 109 is slidably mounted on the positioning frame 108 and contacts the limiting frame 107; the reset component is disposed on the straightening table 101, the limiting frame 107 is a square frame structure, the positioning frame 108 is welded to the bottom of the straightening table 101, the positioning frame 108 is a U-shaped structure, the push rod 109 is driven by a cylinder, and the reset component facilitates the reset of the limiting frame 107. In use, the push rod 109 is pushed downward by the output end of the cylinder, so that the push rod 109 pushes the limiting frame 107 downward, thereby fixing the upper end of the limiting frame 107 to the steel structure.

[0023] Furthermore, the guide rod 110 is fixedly installed on the correction table 101; the reset spring 111 is sleeved on the guide rod 110 and fixedly connected to the limiting frame 107. The guide rod 110 is located on both sides of the bottom of the correction table 101. The bottom of the guide rod 110 is a disc structure. The reset spring 111 is aligned with the axis of the guide rod 110. The reset spring 111 is located below the limiting frame 107. Through the elastic extension and contraction of the reset spring 111, the limiting frame 107 can be easily reset.

[0024] Furthermore, the correction table 101 is provided with a sliding groove 113, and the sliding block 112 is slidably mounted on the correction table 101 via the rotating member and located in the sliding groove 113. The sliding block 112 is provided with a threaded hole, and the sliding block 112 is disposed in the sliding groove 113 on both sides. The rotating member can drive the sliding block 112 to move. By driving the movement of the sliding block 112 through the rotating member, the sliding block 112 drives the sliding frame 103 to move.

[0025] Finally, the mounting plate 115 is fixedly mounted on the straightening table 101; the rotating screw 114 is rotatably mounted on the mounting plate 115 and threaded through the sliding block 112. There are two sets of mounting plates 115, with each set consisting of two plates, and they are arranged on both sides of the straightening table 101. Each set of mounting plates 115 is provided with a set of rotating screws 114. The rotating screws 114 are driven by a motor. In use, the rotating screws 114 rotate under the drive of the motor. The rotating screws 114 drive the sliding block 112 to move within the slide groove 113 through threaded engagement with the sliding block 112.

[0026] In this embodiment, during use, the steel structure is placed on the straightening table 101, with one end of the steel structure positioned below the limiting frame 107. Then, by pushing with a cylinder, the push rod 109 moves downwards along the positioning frame 108. The movement of the push rod 109 pushes the limiting frame 107 downwards, fixing the steel structure onto the straightening table 101. Subsequently, the electric push rod 106 is activated, causing the pressure roller 105 on the mounting frame 104 to abut against the surface of the steel structure. The rotating lead screw 114 is driven by a motor, which causes the sliding block 112 to move within the slide groove 113. The movement of the sliding block 112 causes the sliding frame 103 to move synchronously. The sliding frame 103 then indirectly drives the pressure roller 105 to roll on the surface of the steel structure, effectively correcting the bent parts of the steel structure. By rolling the pressure roller 105 on the surface of the steel structure, the surface of the steel structure is squeezed, thus avoiding excessive deformation of the steel structure during correction.
