The electrophoresis process is to coat the vehicle frame with the surface paint, wherein the electrophoresis process refers to that under certain conditions, under the action of unit electric field intensity, the moving distance (namely, mobility) of charged particles in unit time is constant, and the moving distance is the physicochemical characteristic constant of the charged particles. Different charged particles have different charges or have the same charges but different charge-to-mass ratios, and are electrophoresed in the same electric field and separated from each other due to different moving distances after a certain period of time. The separation distance is proportional to the voltage of the applied electric field and the electrophoresis time.
Under the action of an external direct current power supply, colloidal particles move in a dispersion medium to a cathode or an anode in a directional manner, and the phenomenon is called electrophoresis. Substances are separated by electrophoresis, a technique also known as electrophoresis. The colloid has electrophoresis phenomenon, which proves that the particles of the colloid are charged. The colloidal particles differ in their nature and they adsorb different ions and therefore have different charges.
Electrocoating is a special coating technique that is one of the most common methods for coating metal workpieces. The electrophoretic coating technology began from the research of applying anodic electrophoretic primer to automobiles by ford automobile company in 1959, and built the first generation electrophoretic coating equipment in 1963, and then, the electrophoretic process developed rapidly.
The development of electrophoretic paint and coating technology in China has been over 30 years old, and in 1965, the research institute of Shanghai paint has successfully developed the anode electrophoretic paint; several automobile part anode electrophoresis coating lines have been built in the automobile industry in China by the 70 s. The first generation of anode electrophoretic coating is firstly developed successfully in 1979 by Wujizhao and is applied to military products to a certain extent; then, the development and development work of a large amount of cathode electrophoretic coatings in large and medium-sized paint manufacturing plants such as Shanghai paint institute, Lanzhou paint institute, Shenyang, Beijing, Tianjin and the like are carried out. In the period of six to five, the coating industry of China introduced the manufacturing technology and the coating technology of cathode electrophoretic coatings of factories from Japan, Austria and British. China successively introduces advanced coating technology and coating equipment from America, Germany, Italy and other countries. The first modern cathodic electrocoating line for producing automobile bodies was put into operation in Changchun monocar body factories in 1986, and then the cathodic electrocoating lines of Hubei Eryu and Jinan bodies were put into operation in succession. The situation of adopting cathode electrophoretic coating to replace anode electrophoretic coating is formed in the automobile industry in China, dozens of production lines are put into production in China by the end of 1999, and only more than one hundred thousand cathode electrophoretic coating lines are also put into production before 2000 (for example, hundreds of tons of electrophoresis tank production lines of Changchun one-automobile public automobile company, Shanghai public automobile company, Beijing light automobile company, Tianjin Xiali automobile company, Shanghai Buick automobile company and the like). Cathodic electrophoretic paints have accounted for a large part of the automotive coating market, while anodic electrophoretic paints are active in many other fields. The anode electrophoretic paint is applied to truck frames, black paint parts in the trucks, other metal workpieces with lower corrosion resistance requirements and the like.
Due to the process of the electrophoresis process, before the frame longitudinal beam 10 is subjected to the electrophoresis process to coat the surface paint, the bonding component is required to be installed on the frame longitudinal beam 10, and then the electrophoresis coating process is carried out on the whole frame provided with the bonding component.
The powder spraying process is also called powder coating, and is a novel coating process which is rapidly developed in recent decades, and the used raw materials are plastic powder. Research experiments were started in some countries as early as the forty years, but progress was slow. Polyethylene is successfully coated by a fluidized bed method in Jamm in Germany in 1954, powder coating is formally adopted in production only after electrostatic spraying of powder is invented by Semms company in France in 1962, and in recent years, due to the importance of environment protection of various countries, powder coating without pollution to water and atmosphere is rapidly developed. Spraying powder coating on the surface of a workpiece by using electrostatic powder spraying equipment, wherein the powder is uniformly adsorbed on the surface of the workpiece under the action of static electricity to form a powdery coating; the powdery coating is baked, leveled and cured at high temperature to become final coatings with different effects; the spraying effect is superior to the spraying process in the aspects of mechanical strength, adhesive force, corrosion resistance, aging resistance and the like.
Due to the working procedure of the powder spraying process, when the surface paint is coated by the powder spraying process on the frame longitudinal beam 10, the powder spraying treatment is firstly carried out on the frame longitudinal beam 10 independently, and then the bonding component is installed on the frame longitudinal beam 10.
Because the two coating processes have different advantages and disadvantages, and the two processes are in a coexisting condition, in order to improve the applicability of the frame and the ground under the two coating processes and the conductive effect between the ground and the frame, the ground component is required to achieve a stable conductive effect no matter which process is used for mounting with the frame.
Be equipped with between first installation department 2 and the main part 1 and scrape portion 6 to paint in the smooth and easy scraping mounting hole 11, it is cylindricly to scrape portion 6, circumference evenly arranged has a plurality of strip teeth 7 that are used for scraping paint on scraping portion 6's the periphery, the length of strip tooth 7 is followed scrape 6 axial extensions of portion, form tooth's socket 71 between two adjacent strip teeth 7, tooth's socket 71 is close to the groove depth of main part 1 one side is greater than the groove depth of opposite side.
Further, the depth of the tooth grooves 71 is uniformly reduced from one side toward the other side of the main body 1.
Because the scraping part 6 scrapes off paint in the mounting hole 11 in the process of moving along with the main body part 1, namely, the first mounting part 2 firstly penetrates out of the mounting hole 11 of the frame longitudinal beam 10, and then the first mounting part 2 is pulled out of the mounting hole 11 through the matching relation between the first pressing part 4 and the first mounting part 2, at this time, the paint in the mounting hole 11 has a certain interference effect on the scraping part 6, and the first mounting part 2 is pulled continuously, so that the first mounting part 2 is easily broken, the bonding component cannot be used and can only be wasted, and if a reinforcing plate is additionally arranged on the inner side of the frame longitudinal beam 10 to improve the strength of the frame longitudinal beam 10, but in this state, the bonding component needs to penetrate through the reinforcing plate and the frame longitudinal beam 10 at the same time, at this time, because the scraping part 6 also has an interference effect with the mounting hole 11 of the reinforcing plate, and then the mutual acting force between the first mounting part and the second mounting part is respectively large, and the first mounting part 2 is easier to break in the process of pulling the first mounting part 2.
However, a plurality of rack teeth 7 for scraping off paint are uniformly arranged on the circumferential surface of the scraping part 6 in the circumferential direction, the length of each rack tooth 7 extends along the axial direction of the scraping part 6, the rack teeth 7 damage the inner wall of the mounting hole 11, the connection stability between the rack teeth 7 and the frame longitudinal beam 10 is further improved, the condition of poor contact is avoided, a tooth socket 71 is formed between two adjacent rack teeth 7, the depth of the tooth socket 71 close to one side of the main body part 1 is greater than that of the other side, because the tooth socket 71 does not keep the same depth, that is, when the tooth socket 71 is far away from one side of the main body part 1 and is in first contact with the frame longitudinal beam 10, namely, when the rack teeth 7 scrape off certain paint and are in conductive connection with the frame longitudinal beam 10, the tooth socket 71 is separated from the side close to the main body part 1 and is in contact with the frame longitudinal beam 10, so as to avoid the groove bottom of the rack teeth 71 contacting the frame longitudinal beam 10, avoiding mutual interference, i.e. the interference force between the body of the scraping part 6 and the frame rail 10, and avoiding that it is broken by a continuous pulling force.
It should be added here that when the rack teeth 7 are all embedded in the inner wall of the mounting hole 11, the main body 1 is also prevented from rotating relative to the frame rail 10, so as to improve the connection stability, and importantly, in the actual assembly process, the first mounting portion 2 needs to be installed in the mounting hole 11 of the frame rail 10 first, and the first mounting portion 2 is pulled in the mounting hole 11 of the frame rail 10 through the relative position relationship between the first pressing portion 4 and the first mounting portion 2 until the end surface of the main body 1 is attached to the side wall of the frame rail 10.
The working principle of the embodiment is as follows: through being equipped with two installation departments respectively at main part 1 both ends, install on the frame web through first installation department 2 and the cooperation of first portion 4 that compresses tightly, and second installation department 3 compresses tightly 5 with the second and is connected with bonding wire, so that frame and bonding wire electric connection, and this bonding subassembly still strikes off the paint on the mounting hole 11 inner wall through strip tooth 7, improve the electric conduction effect, avoid contact failure, at this moment, the degree of depth through tooth's socket 71 between strip tooth 7 sets up to both ends inequality, so that during the assembly, rack one end is connected with mounting hole 11 inner wall, the other end can separate with mounting hole 11 inner wall, and then reduce the pulling force to first installation department 2 during the assembly, thereby avoid bonding subassembly to be pulled apart, overall stability is high, reduce the installation degree of difficulty, improve the electric conduction effect of bonding subassembly and frame, effectively avoid the operation damage.
Further, two sides of the main body 1 provided with the first mounting portion 2 and the second mounting portion 3 are both flat.
Because of the process of the electrophoresis process, before the frame longitudinal beam 10 is subjected to the electrophoresis process to coat the surface paint, the bonding component needs to be arranged on the frame longitudinal beam 10, and then the electrophoresis coating process is carried out on the whole frame provided with the bonding component; and the reason of the working procedure of the powder spraying process, when the surface paint is coated by the powder spraying process on the frame longitudinal beam 10, the powder spraying treatment is firstly carried out on the frame longitudinal beam 10 independently, and then the bonding component is arranged on the frame longitudinal beam 10.
The two coating processes have different advantages and disadvantages, and meanwhile, the two processes are in a coexisting condition, so that in order to improve the applicability of the frame and the ground under the two coating processes and the conductive effect between the ground and the frame, a ground component is required to achieve a stable conductive effect no matter which process is adopted to install the ground component on the frame.
Two sides that main part 1 was equipped with first installation department 2 and second installation department 3 are the plane, also namely when electrophoresis technology, 1 one side of main part is laminated with solebar 10 mutually, the main part opposite side is laminated with second locating part mutually, keeps accurate paint spraying effect, avoids above-mentioned terminal surface not laminating and invades certain paint, and then makes it the condition of contact failure appear, leads to the electrically conductive effect unsatisfactory.
In addition, when a powder spraying process is adopted, one side of the main body part 1 is attached to the frame longitudinal beam 10, the other side of the main body is attached to the second positioning part, the main body is further kept, the first pressing part 4 is matched with the first installation part 2, when the first installation part 2 is installed in the installation hole 11, the strip teeth 7 scrape off paint in the installation hole 11, one side of the main body part 1 is attached to the frame longitudinal beam 10, the frame longitudinal beam 10 is prevented from being unsmooth, the end face of the main body part 1 is prevented from being crushed, the deformation of the installation hole 11 is also prevented from extruding the strip teeth 7, and an alignment structure has influence.
