Description

TECHNICAL FIELD

[0001] The application belongs to the field of casting equipment, and particularly relates to a casting sand removing and stress relieving device. BACKGROUND

[0002] In the casting production process, the surface of a casting is often attached with excess sand particles, and stress may be generated in the casting due to uneven cooling. These problems not only affect the appearance of the casting, but also may reduce the mechanical properties and service life of the casting. The traditional sand removing and stress relieving method usually relies on manual knocking, which is not only inefficient but also has limited effect. In order to overcome the shortcomings of manual operation, some casting enterprises also attempt to use simple mechanical equipment for sand removing and stress relieving treatment of the casting. However, these devices often have many deficiencies in design, such as inaccurate control of vibration frequency and amplitude, unreasonable contact mode with the casting, etc., which may cause unnecessary damage to the casting during the treatment process. Therefore, it is necessary to solve the above technical problems. CONTENT OF THE UTILITY MODEL
