1. Dimension and tolerance matching requirements
When the iron damper cover stainless steel stamping parts are assembled on the iron damper, the matching of dimensions and tolerances is the primary assembly requirement. From the diameter point of view, the outer diameter of the stamping part must be precisely matched with the inner diameter of the damper cover. Generally speaking, the clearance should be kept within a very small range. For example, for the assembly of dampers with high precision requirements, the diameter gap between the two may be controlled within ±0.1mm.
The height dimension is also critical. The height of the stamping part must be matched with the depth of the internal structure of the damper to ensure that after assembly, there will be no problem of being too high to affect the compactness of the overall structure, or too low to effectively cover the internal components. At the same time, in terms of shape, the edge contour and angle of the stamping part must be completely consistent with the assembly part of the damper. Any slight shape deviation may cause assembly difficulties and even affect the performance of the damper.
2. Position accuracy requirements
The position accuracy of the iron damper cover stainless steel stamping parts during assembly is crucial. In the plane position, the stamping parts need to be accurately installed at the opening of the damper, and the deviation of the center position should be as small as possible, usually within ±0.05mm, to ensure the subsequent coordination with other parts.
In the axial position, the relative position of the stamping parts and the key parts inside the damper (such as pistons, springs, etc.) must be accurate. If the position is inaccurate, it may cause problems such as obstruction of piston movement and abnormal deformation of springs, which will affect the damping effect and stability of the iron damper. Therefore, during the assembly process, special positioning tools or positioning structures are often required to ensure the position accuracy of the stamping parts.
3. Sealing and connection requirements
Sealing and connection requirements are the focus of the assembly of Iron damper cover stainless steel stamping parts. For sealing, if the damper requires a sealing function, the sealing connection between the stamping parts and the damper must be reliable. This may involve the use of suitable sealing materials, such as rubber sealing rings, and pay attention to the installation position and compression of the sealing rings during assembly.
In terms of connection methods, common ones are bolt connections and snap connections. If it is a bolt connection, the position and size of the bolt holes on the stamping parts must be accurately matched with the corresponding holes on the damper, and the tightening torque of the bolts must also be strictly controlled to ensure the tightness of the connection while avoiding deformation of the stamping parts due to over-tightening. The snap-on connection requires that the snap-on structure on the stamping parts and the damper be reasonably designed, can be smoothly snapped together during assembly, and have sufficient connection strength.
4. Cleaning and surface quality requirements
Before assembly, the assembly parts of the Iron damper cover stainless steel stamping parts and the damper need to be kept clean. Any impurities, oil stains or metal chips may affect the assembly quality. For example, tiny metal chips may be sandwiched between the stamping parts and the damper, causing looseness or abnormal noise after assembly.
The surface quality of the stamping parts will also affect the assembly. The surface should be flat and smooth, without obvious scratches, protrusions or depressions. Because the uneven surface may cause loose fit during assembly, which in turn affects the sealing effect or connection stability. At the same time, for stamping parts with special surface treatment (such as electroplating, passivation), it is necessary to ensure the integrity of the surface treatment layer to avoid damage during the assembly process, thereby affecting its corrosion resistance and overall performance.
