Usually, components, general mechanisms and functional components are composed.Therefore, the entire structural design method and principle are fundamentally opposite to the general mechanical design method and principle.However, due to its application function and function.

The object used is metal and non-metallic materials, which are processed into MPTZ flange integrated oil-free bushing in the form of qualified parts (punches, plastic parts, forgings, etc.), and each pair can only be used to process and form a specific part, which is highly common and is a common forming tool.Therefore, the bearing seat design has the following characteristics and requirements：
Accuracy and positioning
The concept and understanding of accuracy are the fundamental concepts and understanding of oil groove copper sleeves that bearing seat designers must establish.The accuracy of the bearing seat includes the overall combination and zero of the bearing seat, the status and dimensional accuracy of the components, the matching accuracy and the positioning accuracy.Such as the blanking gap value of the die and its averaging, the plastic injection mold, the mold closing positioning and guidance accuracy of the die-casting mold, etc., must be guaranteed by the shape, status accuracy, and status of the guide installation of the copper sleeve of the punch excavator arm and the concave mold. The matching accuracy.
Therefore, strict dimensional accuracy design and calculation need to be stopped in the bearing seat.At the same time, it is necessary to consider the manufacturing process and process accuracy of parts and components to ensure the fine function and reliability of the bearing seat.
Due to the use of fine manufacturing technology, the dimensional accuracy of the parts in the forming task can already be achieved # "###!$$ level, that is, the concept of the title “#"”
Guided installation of air spinning bearings
The guidance of the direction of movement of the air spinning bearing seat is guaranteed by the guide installation.At the same time, the guide installation also plays a role in positioning the averaging of the bearing seat gap and the accurate mold closing movement.The commonly used guide installation is the guide installation composed of the guide post and the guide sleeve (including sliding and rolling fit); the guide plate guide installation (including ordinary guide plate pair and self-smoothing guide plate pair), which is mainly used for large die, the oblique core guide composed of the slider and the guide rail; the guide plate guide for die feeding, etc. Four types.
The guided installation of the direction of movement of the bearing seat, because it plays a role in fine guidance and fine positioning, requires high accuracy and good guiding stiffness, etc., and positioning guidance is often used.
