Description

The invention relates to percussion devices and can be used in various fields of the metalworking industry for stamping products.

The purpose of the invention is to increase productivity, reliability and increase energy consumption due to the interaction of the working and impact elements along the plane.

The drawing shows an automatic branding device, a general view.

The device comprises a housing 1 with a head 2. The inner surface of the housing 1 has two cylindrical sections 3 and 4 with different diameters of a conical section connecting them 5. S housing 1 contains a mechanism 6 for adjusting the impact force, axially spring-loaded core 7 with an anvil 8 and the head 9.

On the 9 face of the head 2 facing the striker 9, an annular eccentric chamfer 10 is made. And on the striker end 9, an annular protrusion 11 acts as a contact element.

The device works as follows.

The core 7 is brought to the workpiece 12 until it touches it. As the housing 1 moves towards the part 12, a spring 13 is placed between the striker 9 and the mechanism for adjusting the impact force. Upon further movement of the housing 1, its conical section 5 connecting the cylindrical sections 3 and 4 interacts with the annular protrusion 11 of the striker 9. The striker 9 is displaced along the working section 14 formed by the difference in diameters of the core 7 and the anvil 8, choosing the eccentricity between the core 7 and the striker 9.

the surface of the work area 14, the striker 9 is moved to interact with the anvil

Core 7. The impact energy of the striker 9 is transferred to the core 7, and the surface of the workpiece 12 is stamped. The impact value is adjusted by means of the impact force control mechanism 6.

The core 7 is returned to its initial position by withdrawing the body 1 from the part 12. By operating the spring 15, which presses the core 7 to the bottom of the head 2, the core 7 moves out of it. The head 9 continues to move with the core 7 until it comes into contact with the annular eccentric chamfer 10. When the annular protrusion 11 of the striker 9 is in contact with the annular chamfer 10, the core 7 is finally pulled out of the striker hole 16

9to stop in the head 2.

At the point when the end face of the striker 9 is located above the end face of the core 7, the striker 9 is displaced along the annular chamfer 10 until the contact of the hole 16 with the anvil 8.
