In the manufacturing process of Mold Accessories, controlling the processing error and deformation is the key to ensure the matching accuracy and interchangeability between accessories.
First of all, reasonable process planning is crucial. Before processing, a scientific processing route should be formulated according to the design requirements and material properties of Mold Accessories. For example, for accessories that need to be processed in multiple processes, the process sequence should be arranged reasonably, first rough processing to remove most of the excess, and then semi-finishing and finishing, gradually improving the processing accuracy and reducing the deformation caused by uneven processing allowance.
Material selection and pretreatment also play an important role in controlling errors and deformation. Select materials with good thermal stability and mechanical properties, and perform appropriate heat treatment on the materials before processing, such as annealing, normalizing, etc., to improve the organizational structure and mechanical properties of the materials, reduce internal stress, and reduce deformation during processing.
Parameter optimization during processing is the core of error control. Reasonable selection of cutting parameters (such as cutting speed, feed rate, and cutting depth) can effectively reduce the generation of cutting force and cutting heat, thereby reducing processing deformation. At the same time, appropriate cooling and lubrication methods are used to promptly remove the heat generated during the cutting process and reduce the impact of temperature on the size and shape of parts.
The design and use of fixtures should not be ignored. Suitable fixtures can ensure accurate positioning and reliable clamping of parts during processing, and prevent displacement and deformation of parts due to improper clamping. In addition, regular precision inspection and maintenance of fixtures are performed to ensure the stability of their positioning accuracy and clamping force.
Heat treatment and aging treatment after processing can further eliminate residual stress and stabilize the size and shape of parts. By tempering and vibration aging treatment of processed Mold Accessories, internal residual stress can be released and the dimensional stability and precision retention of parts can be improved.
In summary, in the manufacturing process of Mold Accessories, reasonable process planning, material selection and pretreatment, processing parameter optimization, fixture design, and subsequent heat treatment and aging treatment can effectively control processing errors and deformations, ensure the matching accuracy and interchangeability between Mold Accessories, and improve the quality and service life of molds.
