Description

Technical Field

[0001] This utility model belongs to the technical field of thermal spraying devices, and in particular relates to a novel thermal spraying device for reinforcing bars. Background Technology

[0002] In engineering fields such as construction, bridges, and transportation, reinforcing steel is an important structural material, and its surface properties directly affect the durability and safety of the project. Thermal spraying technology, by spraying a protective coating onto the surface of reinforcing steel, can significantly improve its corrosion resistance, wear resistance, and other properties, and is therefore widely used in the surface treatment of reinforcing steel.

[0003] Existing rebar thermal spraying equipment has many shortcomings in practical use. On the one hand, traditional clamping devices have relatively fixed structures, making it difficult to adapt to the clamping requirements of rebars of different diameters and shapes. When fixing the rebars, they either cannot stably clamp rebars of special specifications, causing the rebars to shake during spraying and affecting the spraying quality; or they require frequent replacement of clamping components, reducing work efficiency. On the other hand, the rebars are not heated during thermal spraying, resulting in poor adhesion of the sprayed material to the surface of the rebars, easily leading to waste of sprayed material, and failing to guarantee the uniformity and thickness consistency of the coating.

[0004] To address these issues, we provide a novel thermal spraying device for reinforcing bars. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of steel bar thermal spraying device, which solves the problem of the inconvenience of using existing thermal spraying devices by coordinating clamping components, conveying components and rotating spraying components.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a novel rebar thermal spraying device, comprising a base, a conveying assembly fixedly connected to the top of the base, a clamping assembly threadedly connected to one end of the conveying assembly, a spraying assembly fixedly connected to one side of the back of the base, the clamping assembly including a drive motor fixedly connected to the inner cavity of the conveying assembly, a bevel gear fixedly connected to the output shaft of the drive motor, a bevel gear meshing with the surface of the bevel gear, a lead screw fixedly connected to the surface of the bevel gear, and a clamping block threadedly connected to the surface of the lead screw, the spraying assembly including a mounting frame fixedly connected to the top of the base, a support roller, a heating coil, and a spraying head fixedly connected to the bottom of the mounting frame, a rotating ring fixedly connected to the surface of the spraying head via a bearing, a feed pipe connected to the back of the rotating ring, the back of the feed pipe extending through to the back of the mounting frame, a driven gear fixedly connected to one side of the surface of the spraying head, a drive gear meshing with the top of the driven gear, and a drive motor fixedly connected to one side of the drive gear.

[0008] The present invention is further configured such that the conveying assembly includes a movable groove formed on the top of the base, a movable seat slidably connected to the inner cavity of the movable groove, a lead screw two threadedly connected to the bottom of the inner cavity of the movable seat, a support plate fixedly connected to one end of the lead screw two via a bearing, the bottom of the support plate fixedly connected to the top of the base, and a drive motor three fixedly connected to the other end of the lead screw two. A groove for installing the drive motor three is formed on one side of the top of the base. Through the cooperation of the movable groove, the movable seat, the lead screw two, the support plate and the drive motor three, the conveying assembly can realize flexible adjustment of the position of the steel bar conveying, meet different spraying requirements and enhance the applicability of the device.

[0009] The present invention is further configured such that a threaded hole for use with lead screw two is provided at the bottom of the inner cavity of the movable seat, and a sliding groove for accommodating the clamping block is provided on the surface of the movable seat. The end of lead screw one away from bevel gear two is fixedly connected to the inner wall of the sliding groove through a bearing. A mounting groove for installing drive motor one is provided on one side of the movable seat. The design of the threaded hole, sliding groove and mounting groove on the movable seat makes the clamping assembly and the conveying assembly firmly connected, ensures smooth movement of the clamping block, and facilitates the installation and maintenance of drive motor one.

[0010] The present invention is further provided that a rubber pad is fixedly connected to the side of the clamping block that contacts the reinforcing bar, and the surface of the rubber pad is provided with anti-slip texture. The setting of the rubber pad and anti-slip texture on the clamping block increases the friction between the clamping block and the reinforcing bar, further improving the clamping stability of the reinforcing bar and preventing the reinforcing bar from sliding during processing.

[0011] The present invention is further configured such that the support roller is spindle-shaped, and both its front and rear ends are fixedly connected to connecting rods via bearings. The top of the connecting rods is fixedly connected to the bottom of the mounting frame. The spindle-shaped support roller design can better adapt to the shape of the reinforcing bar, support the reinforcing bar while reducing damage to the surface of the reinforcing bar, and ensure the surface quality of the reinforcing bar.

[0012] The present invention is further configured such that an opening is provided on one side of the top of the mounting bracket, the driving gear meshes with the driven gear through the inner cavity of the opening, and a gap is left between the opening and the driving gear. The opening on the mounting bracket is configured to reasonably plan the meshing space between the driving gear and the driven gear, ensuring smooth transmission and avoiding interference between components.

[0013] This invention is further configured such that the bottom of the second drive motor is fixedly connected to the top of the mounting bracket, the back of the mounting bracket has a circular hole for the feed pipe, one side of the spray head is fixedly connected to the inner wall of the mounting bracket via a bearing seat, and the bottom of the second drive motor is fixedly connected to the top of the mounting bracket to ensure stable power transmission and prevent spray angle deviation; the circular hole in the feed pipe provides a precise channel to ensure smooth delivery of the spraying material; the spray head is fixed via the bearing seat, allowing for flexible rotation and strong stability. These three elements work together to optimize the spraying effect.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model utilizes a drive motor to rotate a bevel gear, which in turn drives a second bevel gear to rotate a lead screw, thereby adjusting the position of the clamping block. This allows for stable clamping of steel bars of different diameters and shapes. Compared to traditional fixed-structure clamping devices, it eliminates the need for frequent component replacements, ensuring stable fixation of steel bars of special specifications and preventing the steel bars from shaking during spraying, which could affect quality. It also reduces the number of operation steps and significantly improves the efficiency of steel bar thermal spraying operations.

[0016] 2. The heating coil of this utility model can uniformly heat the steel bars during the conveying process. In conjunction with the rotatable spray head in the spraying assembly, the drive motor drives the active gear, which in turn rotates the driven gear to achieve the rotation of the spray head. This allows for precise control of the spraying angle and spraying amount, solving the problems of uneven heating and inaccurate spraying in traditional devices. It ensures that the sprayed material adheres well to the surface of the steel bars, effectively avoids material waste, guarantees the uniformity and thickness consistency of the coating, and improves the protective performance of the steel bar surface.

The drive motor 31 is started, and through the transmission of the bevel gear 32 and the bevel gear 33, the lead screw 34 drives the clamping block 35 to move, clamping and fixing the reinforcing bar. Then, the drive motor 25 drives the lead screw 23 to rotate, so that the moving seat 22 moves in the moving groove 21, adjusting the reinforcing bar to a suitable position. Subsequently, the conveying assembly 2 drives the reinforcing bar to move. When the reinforcing bar passes under the mounting frame 41, the heating coil 43 heats the reinforcing bar. At the same time, the drive motor 49 drives the drive gear 48 to rotate, and through the driven gear 47, the spray head 44 rotates. The spraying material enters the spray head 44 through the feed pipe 46 and the rotating ring 45, and performs all-round thermal spraying on the heated reinforcing bar to complete the processing of the protective coating on the surface of the reinforcing bar.
