Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to an electrophoretic coating mechanism for pipe processing. Background Art

[0002] Pipe fittings are often encountered in mechanical processing. After some pipe fittings are processed, shaped, polished, they need to be painted on the inner and outer walls of the pipe fittings, especially the outer wall of the pipe fittings, to prevent rust, insulate, and improve mechanical properties. When the pipe fittings are painted by the electrophoretic coating mechanism, the electrophoresis principle is used to make the paint particles in the electrophoretic liquid in the electrophoretic pool migrate and adhere to the inner and outer walls of the pipe fittings through an external electric field to achieve pipe fitting coating. Electrophoretic coating can make the inner and outer walls of the pipe fittings smooth and flat, and is an important means of coating.

[0003] The electrophoretic coating mechanism for pipe processing conveys the pipes to the electrophoretic coating tank for electrophoretic coating via a conveyor rack. When the existing conveyor rack conveys the pipes, it often uses clamps to clamp the pipes or uses straps to wrap and tie the pipes for fixing. The clamps and straps have a certain obstruction on the migration of electrophoretic paint, resulting in the outer wall of the pipe being unable to be completely coated with paint particles at one time. The blocked parts on the outer wall of the pipe need to be additionally sprayed, which affects the production efficiency of the pipe and needs to be improved. Utility Model Content

[0006] A electrophoretic coating mechanism for pipe processing comprises a conveying rod arranged below a conveying rack and a hanging ring fixedly connected to the bottom of the conveying rod, a hanging rod is movably connected to the bottom of the hanging ring, a height-adjusting threaded rod is threadedly connected to the lower end of the hanging rod, a clamping seat is movably connected to the bottom of the height-adjusting threaded rod, two groups of front-to-back symmetrical extrusion arms are horizontally slidably connected in the clamping seat, the extrusion arms are in an L-shape with the extrusion ends bent away from each other, an extrusion column is rotatably connected to the away end of the extrusion arm, the away end of the extrusion column is supported on the inner wall of the pipe, a positive and negative thread adjustment bolt is horizontally rotatably connected to the clamping seat, and the positive and negative thread adjustment bolt is threadedly connected to the extrusion arm.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-3As shown, the utility model provides a technical solution: an electrophoretic coating mechanism for pipe processing, comprising a conveying rod 2 arranged below a conveying rack 1 and a hanging ring 3 fixedly connected to the bottom of the conveying rod 2, a hanging rod 4 movably connected to the bottom of the hanging ring 3, a connecting ring 11 vertically arranged on the top of the hanging rod 4, the bottom of the height-adjusting threaded rod 5 and the top of the clamping seat 6, the hanging ring 3 and the hanging rod 4 are movably connected through the connecting ring 11 on the top of the hanging rod 4, so that the hanging angle is free, avoiding restrictions on the end position of the pipe 10;

[0019] The lower end of the hanging rod 4 is threadedly connected with a height-adjusting threaded rod 5, and the surface of the height-adjusting threaded rod 5 is provided with vertical anti-skid patterns. The height of the lower end of the height-adjusting threaded rod 5 can be changed by rotating the height-adjusting threaded rod 5, so that the hanging pipe 10 is high at one end and low at the other end, which is convenient for draining excess electrophoresis liquid, not only saving electrophoresis liquid, but also shortening the drying time of the paint surface;

[0020] A clamp seat 6 is movably connected below the height-adjusting threaded rod 5. A connecting ring 11 arranged on the height-adjusting threaded rod 5 and the clamp seat 6 is movably connected through a connecting ring 2 12, so that the clamp seat 6 can be movably adapted to the position of the pipe 10 in multiple directions and angles. Two groups of front-to-back symmetrical extrusion arms 7 are horizontally slidably connected inside the clamp seat 6. The extrusion arms 7 are L-shaped with the extrusion ends bent back to back, and are supported and fixed from the inside of the pipe 10 to the outside to avoid obstruction to the coating area of ​​the outer wall of the pipe 10.

[0021] The away end of the extrusion arm 7 is rotatably connected to the extrusion column 8, and the away end of the extrusion column 8 is supported on the inner wall of the pipe fitting 10. The clamp seat 6 is horizontally rotatably connected to the forward and reverse thread adjustment bolt 9, and the forward and reverse thread adjustment bolt 9 is threadedly connected to the extrusion arm 7. A buffer pad is provided at the end of the extrusion column 8 away from the extrusion arm 7 to avoid slipping when fixing.

[0022] Working principle: an adjustable height hanging rod 4 and a height-adjustable threaded rod 5 are provided to adjust the height of the two ends of the hanging pipe fitting 10 below, so as to facilitate the draining of excess electrophoretic liquid on the pipe fitting 10. By raising the two extrusion arms 7 in the clamp seat 6 below the threaded rod 5, the pipe fitting 10 is supported and fixed from the inside to the outside at both ends of the pipe fitting 10. The extrusion column 8 on the extrusion arm 7 will only block the electrophoretic coating paint surface of the corresponding area at the end of the extrusion column 8 on the inner wall of the pipe fitting 10. The blocking area is very small, and there is no obstruction to the outer wall of the entire pipe fitting 10. No subsequent additional spraying is required, thereby improving the processing efficiency of the pipe fitting 10.
