Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a bending device for processing steel structures in building construction. Background Technology

[0002] Steel structures are widely used in modern construction projects due to their high strength, light weight, and ease of construction. Bending and forming is a crucial processing step in the manufacturing of steel structure components, and its quality directly affects the safety and stability of the entire building structure.

[0003] Currently, most steel structure bending devices used on construction sites or in processing plants rely on manual operation to position and clamp the steel structural components to be processed. Operators typically need to rely on experience, visual observation, or the use of simple markings to slowly move the steel structural components to the processing center position of the bending die, and then fix them by manually rotating the screw or turning the clamping handle.

[0004] However, this positioning and clamping method, which relies entirely on manual operation, has significant shortcomings. Due to differences in operator skill and working conditions, the accuracy of manual positioning is difficult to guarantee, and the central axis of the steel structure can easily deviate from the bending center of the equipment. This initial positional deviation directly leads to quality defects in the final bent components, such as curvature deviation, inaccurate angles, and uneven ends. This not only wastes materials and increases rework costs but can also, in severe cases, affect the overall quality of the project. Utility Model Content

[0005] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a structurally improved steel structure processing and bending device for building construction that can effectively solve the above problems.

[0006] The technical solution adopted in this utility model is as follows: A steel structure processing and bending device for building construction includes a pipe bending machine and a bending device mounted on the pipe bending machine; the pipe bending machine also includes a clamping mechanism; the clamping mechanism includes a mounting base fixed to the side wall of the pipe bending machine, a slider slidably connected to the mounting base, an inclined surface provided on the slider, and two clamping components symmetrically arranged on both sides of the slider.

[0007] This invention solves the problems of low efficiency, clamping position deviation, and poor processing accuracy caused by the reliance on manual positioning before bending steel structural components in the prior art. It achieves automatic centering and precise clamping of steel structural components, avoiding curvature deviation or uneven end faces due to positional shift during bending, ensuring that the formed components meet the dimensional and accuracy requirements, and improving the efficiency of single-piece processing preparation.

[0008] As a preferred embodiment of this utility model, the clamping assembly includes a clamping arm, a first rotating shaft, and a second rotating shaft. The clamping arm is rotatably connected to the mounting base via the second rotating shaft, and the first rotating shaft is rotatably connected to the clamping arm. The first rotating shaft abuts against the inclined surface of the slider so that the linear motion of the slider drives the two clamping arms to open and close synchronously.

[0009] As a preferred embodiment of this utility model, the clamping mechanism further includes a motor and a push rod; the motor is mounted on the mounting base, one end of the push rod is connected to the output end of the motor for transmission, and the other end is fixedly connected to the slider.

[0010] As a preferred embodiment of this utility model, the clamping mechanism is disposed on one side of the feed inlet of the bending machine, and is used to center and clamp the steel structure before the steel structure enters the bending machine.

[0015] As a preferred embodiment of this utility model, the bolt can be inserted into the lock groove, and the lock hook is used to engage with the bolt to prevent the bolt from coming out of the lock groove.

[0016] As a preferred embodiment of this utility model, the lock hook is an L-shaped component that can rotate around an axis. The lock hook is rotatably disposed on one side of the lock groove, and the locking or releasing of the lock tongue inserted into the lock groove is achieved by rotation.

[0017] This utility model solves the problem in the prior art where the outer shell of the device is mostly fixed with bolts, resulting in cumbersome disassembly and assembly steps, time-consuming and labor-intensive processes, and long equipment downtime during maintenance. It achieves the technical effect of quickly and tool-free disassembly and assembly of the equipment shell, greatly facilitating the maintenance and troubleshooting of internal core components, significantly shortening downtime, and thus improving equipment maintainability and construction efficiency.

[0018] The beneficial effects of this utility model are as follows: 1. This utility model solves the problems of low efficiency, clamping position deviation, and poor processing accuracy caused by relying on manual positioning before bending steel structural parts in the prior art by setting up a clamping mechanism composed of a motor, push rod, slider, and clamping components.

It achieves the technical effect of quickly and tool-free disassembly and assembly of the equipment shell, which greatly facilitates the maintenance and troubleshooting of the internal core components, significantly shortens downtime, and thus improves the maintainability of the equipment and construction efficiency.

[0020] 3. This utility model transforms the linear motion driven by the motor into a symmetrical clamping action via a slider with an inclined surface and a linkage clamping arm. This solves the problem in the prior art where the adjustment of the clamping structure is cumbersome and it is difficult to quickly adapt to the processing needs of steel of different specifications. It achieves the technical effect of quickly responding to the clamping needs of steel structural parts of different sizes, reducing the adjustment frequency and preparation time when switching workpieces, and enhancing the versatility and automation level of the device.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0025] like Figure 1 As shown, the steel structure processing and bending device for building construction in this embodiment includes a pipe bending machine 1 and a bending device 4 disposed on the pipe bending machine 1. The pipe bending machine 1 also includes a clamping mechanism 2. The clamping mechanism 2 includes a mounting base 23 fixedly connected to the side wall of the pipe bending machine 1, a slider 24 slidably connected to the mounting base 23, and an inclined surface disposed on the slider 24. Two clamping components 25 are symmetrically disposed on both sides of the slider 24. Each clamping component 25 includes a clamping arm 251, a first rotating shaft 252 and a second rotating shaft 253. The clamping arm 251 is rotatably connected to the mounting base 23 through the second rotating shaft 253. The first rotating shaft 252 is rotatably connected to the clamping arm 251 and abuts against the inclined surface of the slider 24 so that the linear movement of the slider 24 can drive the two clamping arms 251 to open and close synchronously.

[0026] Reference Figure 1 and Figure 3The clamping mechanism 2 includes a motor 21 mounted on the mounting base 23 and a push rod 22. One end of the push rod 22 is connected to the output end of the motor 21, and the other end is fixedly connected to the slider 24, for driving the slider 24 to reciprocate on the mounting base 23. Two V-shaped guide grooves are symmetrically opened on the top of the slider 24, and the two inclined surfaces are the side walls of the two V-shaped guide grooves. Two clamping assemblies 25 are symmetrically rotatably connected to the mounting base 23 and located on both sides of the slider 24. Each clamping assembly 25 includes a clamping arm 251, a first rotating shaft 252, and a second rotating shaft 253. The clamping arm 251 is rotatably connected to the mounting base 23 through the second rotating shaft 253, forming... A fixed rotation center is provided, with the rotating shaft 252 rotatably connected to the middle of the clamping arm 251. The rotating shaft 252 is housed in the V-shaped guide groove of the slider 24 and rolls in contact with the inclined surface. This structure allows the two inclined surfaces of the slider 24 to simultaneously push the two rotating shafts 252 when the push rod 22 pushes the slider 24 along the mounting base 23. This, in turn, causes the two clamping arms 251 to synchronously retract inward or open outward around their respective rotating shafts 253 through leverage. This synchronous opening and closing linkage structure ensures that steel structural components of different specifications can be quickly and automatically centered and clamped, ensuring that the steel structure enters the bending machine 4 in a stable and centered posture.

[0027] To ensure that the steel structure is accurately positioned before bending, the clamping mechanism 2 is located on the feed port side of the bending machine 4 to effectively center and clamp the steel structure before it enters the bending machine 4.

[0028] To greatly improve the efficiency of equipment maintenance and repair, please refer to Figure 1 and Figure 4 The outer casing of the pipe bending machine 1 is detachably connected to the main frame of the pipe bending machine 1 via a locking mechanism 3. The locking mechanism 3 includes a locking groove 31 formed on the main frame of the pipe bending machine 1, a locking tongue 33 fixed on the outer casing, and a locking hook 32 rotatably connected to the main frame of the pipe bending machine 1. The shape of the locking tongue 33 is adapted to the opening of the locking groove 31 so as to be inserted into the locking groove 31. The locking hook 32 is an L-shaped component that can rotate around an axis. It is rotatably set on one side of the locking groove 31 and locks or releases the locking tongue 33 inserted into the locking groove 31 by its own rotation. The locking mechanism 3 also includes a handle 34 fixed on the outer casing for conveniently pulling out the outer casing after the locking hook 32 releases the locking tongue 33.

[0029] To ensure a more stable and smooth opening and closing motion of the clamping arm 251, please refer to... Figure 3 The top of the slider 24 has two symmetrically formed V-shaped guide grooves, and the two inclined surfaces are the side walls of the two V-shaped guide grooves. The two rotating shafts 252 are respectively housed in the two V-shaped guide grooves and form rolling contact with the inclined surfaces. This structure ensures that the rotating shafts 252 are always stably guided when moving with the clamping arm 251, avoiding deviation.

[0030] The clamping mechanism 2 also includes a motor 21 and a push rod 22; the motor 21 is mounted on the mounting base 23, one end of the push rod 22 is connected to the output end of the motor 21 for transmission, and the other end is fixedly connected to the slider 24, thereby providing a stable and controllable driving force for the reciprocating linear motion of the slider 24.

[0031] Working principle: When clamping and centering the steel structure, the steel structure is first placed on the slider 24, and then the motor 21 is started. The motor 21 drives the push rod 22 to push or retract the slider 24, so that it moves along the plane of the mounting base 23. During this process, the inclined surface of the slider 24 will push the two rotating shafts 252. Since the rotating shaft 253 rotatably connects the clamping arm 251 to the mounting base 23, the two clamping arms 251 will make synchronous circular motion around the rotating shaft 253 under the drive of the rotating shaft 252, thereby realizing the retraction or opening of the two clamping arms 251, completing the rapid automatic centering and clamping of the steel structure, so that the steel structure enters the bending machine 4 in a stable and precise aligned position.

[0032] When locking or disassembling the casing of the pipe bending machine 1, when locking, multiple locking hooks 32 are lifted to remove obstruction to the locking tongue 33, and multiple locking tongues 33 on the casing are placed into multiple locking slots 31 on the main frame of the pipe bending machine 1. Then, multiple locking hooks 32 are lowered, and the locking hooks 32 will lock the locking tongue 33 to prevent it from falling off. When disassembling, simply lift multiple locking hooks 32 and pull the handle 34 outward to complete the quick disassembly of the casing. The process does not require complicated tools and greatly improves maintenance efficiency.

[0033] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
