Description

Technical Field

[0001] This utility model relates to the technical field of steel structure production equipment, specifically a surface treatment device for steel structure production. Background Technology

[0002] Steel structure is a structural system constructed primarily of steel. It is one of the mainstream structural types in the modern construction field. Due to its high strength, light weight, good overall rigidity, and strong deformation capacity, steel is widely used in projects such as large-span factories, super high-rise buildings, stadiums, and bridges. Surface treatment of steel structures is a fundamental step in the coating process, directly affecting corrosion resistance and service life. During rolling, storage, transportation, and processing, steel surfaces accumulate contaminants such as iron oxide scale, rust, welding slag, burrs, and oil stains. If these are not thoroughly removed, coating adhesion will be significantly reduced, leading to coating peeling or appearance defects. Traditional surface treatment equipment commonly suffers from insufficient adhesion between the grinding belt and the workpiece surface when grinding cylindrical steel. The curved surface characteristics of cylindrical steel require dynamic adjustment of the grinding belt's pressure and angle to achieve full coverage. Existing equipment mostly uses fixed grinding mechanisms, which cannot adaptively adjust according to changes in the steel diameter. This results in incomplete grinding of end faces, inner wall corners, or curved transition areas, leaving residual rust and burrs that affect coating adhesion. To compensate for insufficient adhesion, some equipment uses multiple grinding passes or increased pressure, but this easily leads to excessive wear on the steel surface, uneven thickness, and even deformation. Therefore, a surface treatment device for steel structure production is proposed to solve the above problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a surface treatment device for steel structure production. It features an adaptively adjustable grinding component that allows the annular grinding belt to closely conform to the curved surfaces of cylindrical workpieces of different diameters, achieving uniform, efficient, and dead-angle-free grinding. This solves the problems in existing technologies where grinding devices easily lead to excessive wear, uneven thickness, or even deformation of the steel surface.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a surface treatment device for steel structure production, comprising a conveying assembly for fixing the steel structure, the conveying assembly including a base, the base being provided with an adjustment assembly for adjustment, and the adjustment assembly being provided with a grinding assembly for grinding the steel structure. The base is also provided with a first slide rail for support. A first transmission motor for transmission is provided at one end of the first slide rail. The output shaft of the first transmission motor is fixedly connected to a first transmission screw. The first transmission screw is threadedly connected to a first slide table. The first slide table is slidably connected to the first slide rail. The first slide is equipped with a chuck drive motor for transmission, and the output end of the chuck drive motor is equipped with a six-jaw chuck for fixing the steel structure.

[0005] Furthermore, the adjustment assembly includes a mounting base vertically mounted on a mounting seat, a second slide rail provided on the mounting base, a second slide table slidably connected to the second slide rail, a second transmission motor for transmission provided at one end of the mounting base, a second transmission screw connected to the output of the second transmission motor, and the second transmission screw threadedly connected to the second slide table.

[0006] Furthermore, the grinding assembly includes a support frame fixedly mounted on the second slide. The support frame is rectangular, with a first tensioning wheel at its bottom and an adjusting component at its top. The adjusting component includes a support arm fixedly mounted on a support frame, an adjusting arm for adjustment is provided at the top of the support arm, and an adjusting wheel is provided on the adjusting arm; The support frame is also equipped with an electric push rod, the output end of which is connected to the adjusting arm.

[0007] Furthermore, the bottom of the electric push rod is hinged to the support frame via a hinge shaft and a hinge sleeve, wherein the diameter of the hole in the hinge sleeve is larger than the diameter of the hinge shaft.

[0008] Furthermore, a mounting frame is provided at one end of the support frame. The mounting frame has an arc-shaped structure with clearance wheels at both ends. A grinding belt for grinding the steel structure is provided between the clearance wheels, the first tension wheel, and the adjusting wheel.

[0009] Furthermore, the conveying assembly is also provided with a support member to facilitate the conveying of the steel structure. The support member includes a support leg for support, and a conveying trough is provided on the top of the support leg. The trough has multiple circular protrusions inside.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: I. This surface treatment equipment for steel structure production utilizes an adaptive adjustment mechanism driven by an electric push rod. This mechanism dynamically adjusts the wrap angle and pressure of the grinding belt on the workpiece, ensuring optimal contact between the grinding belt and the curved surfaces of cylindrical workpieces of varying diameters. This effectively solves the problems of insufficient contact, grinding dead angles, and uneven pressure inherent in traditional fixed grinding mechanisms. It achieves full coverage and thorough grinding of the workpiece's outer surface, completely removing oxide scale, rust, and burrs, significantly improving surface cleanliness. This provides an excellent base for subsequent coating, significantly enhances coating adhesion, and extends the service life of the steel structure.

[0011] II. This surface treatment equipment for steel structure production integrates automatic workpiece rotation, axial feeding, and adaptive grinding of the grinding head. Its high degree of automation reduces manual intervention and labor intensity, achieving the desired effect in a single grinding pass. Compared to traditional processes requiring multiple grinding passes or manual adjustments, this significantly improves work efficiency. Furthermore, by avoiding excessive pressure or repeated grinding to compensate for poor fit, it prevents problems such as steel wall thinning, surface damage, and even deformation caused by excessive wear, better protecting the workpiece's geometric dimensions and mechanical properties, thus meeting the requirements of high-quality manufacturing.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This embodiment of a surface treatment device for steel structure production includes a 1 for fixing the steel structure, a base on the 1, an adjustment 2 on the base, and a 3 for grinding the steel structure on the 2. The base is also provided with a support 11, one end of which is provided with a transmission 12, the output shaft of 12 is fixedly connected to 13, 13 is threadedly connected to 14, and 14 is slidably connected to 11. 14 is equipped with 15 for transmission, and 16 is provided at the output end of 15 for fixing the steel structure.

[0016] 1 is still equipped with 4 to facilitate the transport of steel structures. 4 includes support legs for support, and a transport trough is provided on the top of the support legs. The trough has multiple circular protrusions inside.

[0017] In Example 1, the operator places the cylindrical steel workpiece to be processed horizontally, with one end clamped and fixed by a six-jaw chuck 16. The six-jaw chuck 16 is driven by a chuck drive motor 15, which rotates the workpiece around its own axis. The first transmission motor 12 starts, driving the first transmission screw 13 to rotate, which in turn drives the first slide 14, threadedly connected to it, to move horizontally along the first slide rail 11. Since the workpiece is fixed on the chuck of the first slide 14, it can also perform axial feed motion while rotating. To assist in supporting the long workpiece, a support member 4 is provided on the conveying path. Multiple circular protrusions inside the conveying trough at its top reduce frictional resistance during workpiece movement and provide stable support.

[0018] 2 includes 21, which is vertically mounted on a mounting base. 22 is provided on 21. 23 is slidably connected to 22. 24 is provided at one end of 21 for transmission. 25 is connected to the output of 24. 25 is threadedly connected to 23.

[0019] In the second embodiment, the mounting base 21 is fixedly installed on the equipment base, located on one side of the conveying assembly 1. When the workpiece needs to be polished, the second drive motor 24 is started, driving the second drive screw 25 to rotate, which in turn drives the second slide table 23, which is threadedly connected to it, to move horizontally along the second slide rail 22. This adjusts the position of the polishing assembly 3 mounted on the second slide table 23, allowing the polishing belt 38 to move towards the workpiece, thus achieving the desired polishing effect.

[0020] 3 includes a rectangular 31 fixedly mounted on 23, with a 32 at its bottom and a 34 at its top. 34 includes a support arm fixedly mounted on 31, with an adjustment arm at its top for adjustment, and a 35 on the adjustment arm. 31 also includes a 33, the output end of which is connected to the adjustment arm. The bottom of 33 is hinged to 31 via a hinge shaft and a hinge sleeve, the hole diameter of which is larger than the diameter of the hinge shaft. One end of 31 has a 36, ​​which is an arc-shaped structure with 37 at both ends. A 38 for grinding the steel structure is located between 37, 32, and 35.

[0021] In embodiment 3, the grinding assembly 3 is fixed to the second slide table 23 by the support frame 31, and the annular grinding belt 38 is sleeved on the first tensioning wheel 32, the adjusting wheel 35 and the two clearance wheels 37. The two clearance wheels 37 are installed at both ends of the arc-shaped mounting bracket 36, with their arc shape facing the workpiece. This makes the grinding belt 38 form an open "C"-shaped opening before contacting the workpiece, which facilitates the entry of the workpiece.

[0022] Core Adaptive Process: When the workpiece enters the "C"-shaped area of ​​the grinding belt 38 during rotation and feeding, its cylindrical surface contacts the inner side of the grinding belt 38. The electric push rod 33 operates, pushing or pulling the adjusting arm, thereby changing the position of the adjusting wheel 35. Since the bottom of the electric push rod 33 is hinged to the support frame 31, and the diameter of the hinge bushing is larger than the shaft diameter, providing a margin of movement, this action dynamically adjusts the tension of the grinding belt 38 and its wrapping angle relative to the workpiece.

[0023] Through control methods not shown in the control diagram but which are conventional in the art, the electric push rod 33 can apply and maintain a constant pressure, ensuring that the grinding belt 38 can closely adhere to the curved surface of the workpiece regardless of changes in the workpiece diameter. As the workpiece rotates and moves axially, the grinding belt 38 performs continuous and uniform grinding on its outer cylindrical surface.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
