Problems solved by technology

The surface coating and protection operations of this type of pipe fittings are more complicated. At present, when coating and protecting the surface of pipe fittings, it mainly relies on tools such as spray guns and brushes. Although the coating operation can also be achieved, the overall paint film thickness Uniformity, stability, and avoiding paint entering the tube during spraying are still lacking

Embodiment 1

[0022] Embodiment 1: as figure 1 In the shown embodiment, a pipe fitting pretreatment device includes a dipping tank 1, a main frame 2, and several dipping oil cylinders 21 above the main frame. The piston rod of the covered oil cylinder is connected with the main frame. The main frame is provided with a fixed splint 22 and a movable clamp oil cylinder 23. The piston rod of the movable clamp oil cylinder is provided with a movable splint 24. The surface of the fixed splint and the movable splint are both perpendicular to the horizontal plane. One plate surface of the fixed splint is opposite to one plate surface of the movable splint, and a pipe fitting clamping part is formed between the fixed splint and the moving splint. In the material barrel 3, elastic gaskets 25 are provided on the fixed splint and the movable splint, and the elastic gasket is located between the fixed splint and the movable splint. The movable splint can be moved by the passive clamping oil cylinder to...

Embodiment 2

[0024] Embodiment 2: the basic structure and implementation mode of this embodiment are the same as embodiment 1, and its difference is, as figure 2 As shown in , the paint bucket is provided with a paint leveling structure, the paint leveling structure includes a paint leveling shaft 31 that can rotate around its own axis, and a number of paint leveling blades 311 arranged on the paint leveling shaft. The blade is in the paint bucket, and also includes a paint leveling motor 32 for driving the paint leveling shaft to rotate. The output end of the paint leveling motor is connected to the input end of a paint leveling reducer 321, and the output end of the paint leveling reducer is connected to the paint leveling shaft. We know that paints (paints, coatings, protective paints, etc.) are not a single solution, they may be suspensions, emulsions or a mixture of various raw materials (and in many cases, only one kind of paint is used, There are often two or more kinds of paint m...

Embodiment 3

[0025] Embodiment 3: the basic structure and implementation mode of this embodiment are the same as embodiment 2, and its difference is, as Figure 3 to Figure 7As shown in , it also includes a bucket base 4, the bucket base is relatively fixed to the ground, and the paint bucket is composed of a tubular barrel body 3a, a disc-shaped barrel top plate 3b, and a disc-shaped barrel bottom plate 3c. There is a paint inlet 3d on the top plate, a paint discharge pipe 3e connected to the inside of the paint bucket is provided on the bottom plate of the bucket, a paint discharge valve 3f is arranged on the paint discharge pipe, the paint bucket is rotatably connected with the bucket base, and the paint bucket The axis of rotation is the barrel axis, below the barrel is provided with a rotary drum motor 33 for driving the paint bucket to rotate along the barrel axis, the output end of the rotary drum motor is connected to the input end of a rotary drum reducer 331, and the rotary drum d...

Abstract

The invention discloses a pretreatment device for a pipe fitting. The pretreatment device for the pipe fitting comprises a soaking and covering tank, a main rack and a plurality of soaking and covering oil cylinders located above the main rack. The telescopic direction of piston rods of the soaking and covering oil cylinders are the vertical direction. The piston rods of the soaking and covering oil cylinders are connected with the main rack. A fixed clamping plate and a movable clamping oil cylinder are arranged on the main rack. A movable clamping plate is arranged on a piston rod of the movable clamping oil cylinder. The faces of the fixed clamping plate and the faces of the movable clamping plate are perpendicular to the horizontal plane. One plate face of the fixed clamping plate is opposite to one plate face of the movable clamping plate. A pipe fitting clamping part is formed between the fixed clamping plate and the movable clamping plate. The soaking and covering tank is located below the pipe fitting clamping part and is connected to a paint barrel through a liquid inlet pipe. The pretreatment device for the pipe fitting has the beneficial effects that the outer surface of the pipe fitting can be effectively coated with a paint film, and paint is comprehensively and evenly attached to the coated part; the coating process is completed at a time, efficiency is high, and effects are good; and the paint can be prevented from entering the pipe fitting, and coating pertinence is strengthened.

Description

technical field [0001] The invention belongs to the technical field of pipe fitting spraying, in particular to a pipe fitting pretreatment device. Background technique [0002] At present, there are many pipe fittings (or tubular parts) that need to be painted for surface protection (anti-rust, anti-scratch, etc.), but the inner (inner pipe) surface does not want to be coated with paint film. The surface coating and protection operations of this type of pipe fittings are more complicated. At present, when coating and protecting the surface of pipe fittings, it mainly relies on tools such as spray guns and brushes. Although the coating operation can also be achieved, the overall paint film thickness Uniformity, stability, and avoiding paint from entering the tube during spraying are still lacking. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a pipe fitting that can quickly and effectively coat the...
