Description

one

The invention relates to the machining of parts by the method of surface plastic deformation and can be used in hardening blanks before stamping,

The purpose of the invention is to increase productivity: processing.

The drawing shows the device section.

The device contains an ultrasonic transducer 1 with a hub 2 of longitudinal vibrations with which the deforming rods 3 interact. The cradle 4 for details, for example steel sheet 5, is made in the housing 6. The ultrasonic transducer with the hub 2 longitudinal rings; the deformation and deforming rods 3 are located under the cradle, four. A damper 7 is installed on the opposite side of the cradle 4 for exciting resonant oscillations with deforming rods 8 interacting with it. The deformation of the rods 8 are located opposite the deforming station 3, and the height of the bump is equal to the length of the sound wave.

Into devices; can be used as a magnetostrictive transducer

developer of longitudinal oscillations, and piezoceramic. The geometry of the microrelief of the surface of the parts obtained after processing, is determined to be 5 with the radius of the working sphere of the deforming rods and usually it is chosen within 0, 5-1.5 mm.

The device works as follows.

A steel sheet 5 is mounted on the cradle 4, the ultrasonic frequency voltage is applied to the ultrasonic transducer 1, which excites ultrasonic vibrations of the longitudinal oscillation concentrator 2 and deformed rods, which begin to process the surface of the steel sheet 5. Through the steel sheet 5, ultrasonic vibrations are transmitted to the rods 8 and the screen 7, which begins to oscillate at a resonant frequency, causing the deforming rods 8 to move in the direction of the steel sheet 5, which processes the underside of the steel sheet 5.

The proposed device allows machining of parts simultaneously from two sides, which increases its productivity.
