Description

Technical Field

[0001] This utility model relates to the field of thermal spraying technology, and more specifically to a thermal spraying coating equipment. Background Technology

[0002] Thermal spraying is a surface treatment technology that uses high-pressure gas to spray molten or semi-molten coating material onto the surface of a workpiece. The coating material cools on the workpiece surface to form a protective layer. Generally, thermal spraying enhances the workpiece's anti-oxidation and abrasion resistance properties. A search revealed an existing technology (publication number: CN202322606918.8) for a thermal spraying coating device. The description states that "this utility model uses two fixed frames, an electric telescopic rod, and clamping plates in cooperation. The electric telescopic rod drives the clamping plates to move, facilitating the clamping of both ends of the workpiece between the two plates for fixation. Furthermore, the cooperation of the mounting groove, servo motor, lead screw, drive block, and guide rod facilitates the horizontal movement of the ring-shaped spray gun and nozzle, allowing for uniform spraying of the workpiece's outer wall from multiple directions." However, the existing technology suffers from the problem that the end faces of the workpiece clamped between the clamping plates are difficult to be sprayed by the ring-shaped spray gun, affecting the coating efficiency. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a thermal spraying coating device is provided to solve the problem that the end face of the workpiece clamped between the clamps is difficult to be sprayed by the annular spray gun, which affects the coating process efficiency.

[0004] To achieve the above objectives, a thermal spraying coating device is provided, comprising: a thermal coating machine and an annular spray gun, wherein the annular spray gun is connected to the inner wall of the thermal coating machine via an electric slide table.

[0005] The left and right inner walls of the hot coating machine are connected to coating clamps via electric push rods. The coating clamps are connected to limit partitions via electric guide rail mechanisms. A blower hood is welded to the side end face of the coating clamp. An arc-shaped exhaust mesh and a side exhaust port are provided on the inner cavity surface of the blower hood. The arc-shaped exhaust mesh and the side exhaust port are connected to the fan via branch pipes. Coating nozzles are installed on the front and rear inner walls of the blower hood and the groove wall of the coating clamp.

[0006] Furthermore, a viewing door is installed on the front surface of the thermal coating machine, a coating nozzle is installed in a ring on the inner side of the annular spray gun, and coating clamps are symmetrically distributed on the left and right sides of the annular spray gun.

[0007] Furthermore, a paint hot melt box is fixed at the upper end of the hot coating machine, and fans are provided on the left and right sides of the paint hot melt box. The paint hot melt box is connected to the annular spray gun through a material supply pipe.

[0008] Furthermore, the fan side is connected to a main air supply pipe, and the lower end of the main air supply pipe is connected to two sets of branch pipes through pipe joints; and the two sets of branch pipes are distributed and connected to the upper and lower surfaces of the two sets of blower shrouds.

[0009] Furthermore, the limiting partition is located at the connecting cavity between the blower hood and the coating clamp, and an electric guide rail mechanism is connected to the upper end of the limiting partition.

[0010] Furthermore, the upper and lower inner cavities of the blower hood are symmetrically distributed with arc-shaped exhaust ports; and the side exhaust ports are symmetrically distributed at the front and rear inner cavities of the blower hood.

[0011] Furthermore, an air supply chamber is provided inside the blower hood, and the arc-shaped exhaust vent and the side exhaust vent are connected to the branch pipe through the air supply chamber.

[0012] The beneficial effects of this utility model are as follows: the thermal spraying coating equipment of this utility model uses a limiting partition sealed inside the coating clamping plate cavity to clamp both ends of the workpiece to be sprayed, so that both ends of the workpiece to be sprayed are inside the blower hood. The blower delivers air to the arc-shaped exhaust vent and side exhaust vent inside the blower hood. The high-pressure air blown from multiple directions suspends both ends of the workpiece to be sprayed in the inner cavity of the blower hood, so that the two coating nozzles spray the coating material onto the clamped end face of the workpiece. This facilitates more thorough and comprehensive spraying of the workpiece by the coating equipment, effectively avoids uneven coating distribution caused by batch spraying on the surface of the workpiece, enhances the uniformity of the coating spraying by the coating equipment, and improves the coating processing efficiency of the coating equipment.

[0019] The inner walls of the left and right sides of the hot coating machine 1 are connected to the coating clamping plate 4 by electric push rod 41. The coating clamping plate 4 is connected to the limit partition 43 by electric guide rail mechanism 42. The side end face of the coating clamping plate 4 is welded with the blower hood 5. The inner cavity of the blower hood 5 is provided with arc-shaped exhaust net 51 and side exhaust vent 54. The arc-shaped exhaust net 51 and side exhaust vent 54 are connected to the fan 3 by branch pipe 32. The inner walls of the front and rear sides of the blower hood 5 and the groove wall of the coating clamping plate 4 are all equipped with coating nozzles 2 52.

[0020] First, clamp the two ends of the workpiece between the limiting partitions 43 located on the side of the coating clamping plate 4, close the cabinet door of the thermal coating machine 1, and move the annular spray gun 2 back and forth on the surface of the workpiece. After the coating nozzle 21 in the annular spray gun 2 sprays the surface of the workpiece, turn on the fan 3 to discharge high-pressure air from the arc-shaped exhaust port 51 and the side exhaust port 54 in the blower hood 5, blowing the workpiece to the center. Then control the limiting partition 43 to move outward. At this time, the workpiece is in a suspended state. Then control the coating nozzle 52 to spray the coating material on the surface of the workpiece in the blower hood 5, thus completing the thermal spraying process of the workpiece.

[0021] In this embodiment, a viewing door 13 is installed on the front surface of the thermal coating machine 1, and a coating nozzle 21 is installed in a ring on the inner side of the annular spray gun 2.

[0022] As a preferred implementation, the viewing door 13 facilitates observation of the spraying process of the thermal coating machine 1. The annular spray gun 2 sprays paint onto the surface of the workpiece held between the coating clamps 4 through multiple sets of coating nozzles 21. The paint melting tank 11 melts the paint and delivers it to the coating nozzles 21 and 52 via the supply pipe 12. An air outlet is provided on the rear inner wall of the thermal coating machine 1 to facilitate the removal and purification of odors within the machine.

After the workpiece surface is coated by the limiting partition 43, the electric guide rail mechanism 42 is controlled to open the limiting partition 43, so that the coating nozzle 52 installed on the groove wall of the coating clamping plate 4 is exposed.

[0027] In this embodiment, arc-shaped exhaust vents 51 are symmetrically distributed on the inner surfaces of the upper and lower ends of the blower hood 5; and side exhaust vents 54 are symmetrically distributed on the inner surfaces of the front and rear ends of the blower hood 5.
