Repair automobile parts by electroplating

The damage of automobile parts mainly includes four types: deformation, fracture, corrosion and wear. The first three types of damage are usually repaired by cold working, hot working or gluing. If the general parts deformation can be cold-pressed or hot-pressed after correction for mechanical repair; shaft parts can be broken by inlaying, welding, forging and other methods to repair; cylinder block water jacket cracks can be repaired by welding, riveting or adhesive methods. Parts wear is the most common damage. Parts that have not worn out beyond the specified repair size are processed according to repair size. Parts that have worn out beyond the repair size are repaired by surfacing, spraying, electroplating and other metal covering processes and adhesive methods. Electroplating Repair Method This method is to use the part to be repaired as the cathode, so that the metal cations in the electrolyte move toward the part (cathode) under the action of electric field force, and deposit on the surface of the part. The advantage of the electroplating method is that it can obtain a good wear resistant layer and no distortion of the parts. Chromium plating is often used to repair automobile parts, followed by iron plating chromium plating and iron plating are both electrode crystals, with similar ultra-fine grains and high dislocation structure and large internal stress, and is stratified, with a large number of microcracks. But the chromium plating layer and the iron plating layer have their own characteristics, such as high hardness, good wear resistance, and prolonging the service life of the parts. The disadvantages are low current efficiency, slow deposition, thin coating, high cost, and highly toxic chromium anhydride, serious environmental pollution. The electrolyte temperature of iron plating used to be above 90 C, which can reduce the internal stress of the coating and prevent peeling, but the hardness of the coating is on the low side. In 70s, the wear resistance and the bonding strength of the coating were increased by using low temperature iron plating at 45 C. Iron plating also has the advantages of fast accumulation, low cost and no pollution to the environment.

Carbon dioxide welding to repair auto parts

The significance of automotive parts repair is to repair old and waste, reduce the consumption of new parts, thereby saving raw materials, energy and manpower for manufacturing parts.  The damage of automobile parts mainly includes four types: deformation, fracture, corrosion and wear. The first three types of damage are usually repaired by cold working, hot working or gluing. If the general parts deformation can be cold-pressed or hot-pressed after correction for mechanical repair; shaft parts can be broken by inlaying, welding, forging and other methods to repair; cylinder block water jacket cracks can be repaired by welding, riveting or adhesive methods. Parts wear is the most common damage. Parts that have not worn out beyond the specified repair size are processed according to repair size. Parts that have worn out beyond the repair size are repaired by surfacing, spraying, electroplating and other metal covering processes and adhesive methods. Automatic surfacing is to install parts on the surfacing machine and turn them on side. Commonly used automatic surfacing has three technologies: vibration surfacing, carbon dioxide protection welding and submerged arc welding.  Carbon dioxide protection welding is carried out under the covering of carbon dioxide gas. Because carbon dioxide can react with carbon in molten iron to form carbon monoxide at high arc temperature, some carbon monoxide gases escaped from molten iron pool and become pores in the welding layer, thus affecting the surfacing quality.  Therefore, in order to reduce the porosity, carbon dioxide shielded welding mostly uses special low-carbon manganese-silicon alloy steel wire with low carbon content and sufficient deoxidizer. The wire diameter is 0.4-0.6 mm. The surfacing layer has high strength, few pores and no cracks, but the hardness is low. This method is suitable for repairing cab, leaf plate and other thin plate parts.

Inspection of rolling bearings for automobiles

Rolling bearings on automobiles include ball bearings, roller bearings, tapered bearings and needle roller bearings. They often work under high speed and heavy load conditions and bear considerable alternating loads. Therefore, rollers and raceways often produce serious wear, fatigue spalling, fracture, ablation (that is, high temperature annealing, serious, the color is purple black, similar to blue) and other phenomena. When rolling bearing, a component usually does not need to decompose and check the damage condition of each part. When inspecting, the bearings are cleaned and rubbed. The quality of the bearings can be appraised by means of external inspection, idling test and internal clearance inspection if necessary. (1) appearance check. In the inspection, if the following damage phenomena are found, they should be replaced in time. Rollers (ball, cylindrical roller, tapered roller, needle) and internal and external raceways are discolored by ablation; in the internal and external raceways of bearings, there are impact marks, marks and scratches; in the internal and external raceways of bearings, rolling bodies (ball, cylindrical roller, tapered roller, needle) on the occurrence of cracks, metal delamination, scaly peeling and a large number of (ball, cylindrical roller, tapered roller, needle) Usually more than one third of the area) black spots; excessive wear in the groove of the retaining roller, the roller can fall out by itself; due to tapered roller wear, its small end of the working face protruding out of the bearing outer seat ring end; tapered roller bearing inner ring large end of the internal end of the notch and metal spalling. In the inspection of rolling bearings, if only minor corrosive black spots are found in the bearings and minor defects in the cage are found, without affecting the rotation of the bearings, they can generally continue to be used. (2) idling inspection. The experiment mainly depends on whether the bearing rotates flexibly, whether there is noise or whether it is stuck or not. The inhomogeneity of the bearing rotation can be judged from the feeling on the hand (the old bearing is allowed to have a slight noise). (3) internal clearance check. The measurement of internal clearance and wear of ball bearings can be judged by measuring their radial and axial clearance. Axial clearance inspection: the bearing outer seat ring is placed on two cushion blocks, and the inner seat ring is suspended, and then a small plate is placed on the inner seat diagram, the dial stylus against the center of the plate, the maximum allowable value of axial clearance is 0.20 ~ 0.25 mm. Radial clearance inspection: Place the bearing on a flat plate so that the dial gauge stylus against the bearing outer seat, and then hand press the bearing inner ring, the other hand reciprocating push the bearing outer ring, the number of meter needle swing is the radial clearance of the bearing. The maximum allowable value of radial clearance is 0.10~0.15mm.

Grinding of automobile parts

Grinding is the process of grinding metal with a grinding wheel on a grinder. Grinding is one of the main methods of finishing. In the automobile industry, the grinding machine accounts for about 25%. Therefore, finishing and grinding of hardened materials is a common method. In addition, grinding is easy to automate, and is conducive to efficient production. Grinding has the following characteristics: 1. The grinding wheel has high abrasive hardness and good heat resistance, so it can grind hard materials that metal tools can not process. 2. Grinding can remove very thin and very fine chips, the chip thickness is generally only a few microns, therefore, has a strong correction ability, processing accuracy can reach T6~IT5, surface roughness of Ra0.1 micron. 3. high grinding speed. 4. The cutting temperature is high, and the instantaneous maximum can reach 1000 degrees Celsius. Therefore, the grinding surface is easy to produce residual stress, burn and crack. According to the geometry of the object, grinding can be divided into outer circle, inner circle, plane and formed surface. By clamping and driving the workpiece, it can be divided into centering grinding and centerless grinding. According to the feed direction, it can be divided into longitudinal feed and transverse feed. According to the working surface types of grinding wheels, they can be divided into peripheral grinding, end grinding and peripheral grinding. The types of grinding machines commonly used in automobile manufacturing are ordinary grinder and special grinder. Ordinary grinder includes: cylindrical grinder, internal grinder, surface grinder, centerless grinder, etc. Special grinding machines include camshaft grinder, crankshaft grinder, cross shaft grinder and so on.

Auto parts repair

Repairing methods for worn parts can be divided into two categories: machining worn parts to restore the correct geometric shape and fit characteristics, and obtaining new geometric dimensions. Surfacing, spraying, electroplating and electroless plating are used to supplement the worn parts, or expanding (reducing) upsetting is used to increase (or reduce) the size of the worn parts, and then mechanical processing is carried out to restore the nominal size, geometry and surface roughness. Repair of deformed parts can be done by pressure correction and flame straightening. The cracks and damages on the parts can be repaired by welding, brazing, bench work or bonding. The worn parts are machined by repairing dimension method and inserting sleeve method to make them have correct geometry. Repair dimension method is widely used in automobile repairing. In order to balance the service life of parts, repair dimension method is used in many parts, such as cylinder, piston, piston ring, piston pin, crankshaft and bearing, which have high wear rate and short service life. In automobile use, some of them are only local wear or abrasion. When the structure and strength permit, the wear parts can be reduced (shaft) or enlarged (hole) to a certain size (usually 2-3 mm) and then embedded into a sleeve by interference fit method to restore the basic size of the repair process. Such as: cylinder liner, valve guide and all kinds of bushing. Thanks for the help of Feilong Jiangli
