Abstract

The invention relates to impact devices. The purpose of the invention is to increase reliability. The core is brought to the workpiece. When moving the body to the part, its conical section interacts with the annular protrusion of the hammer, which moves along the working section, choosing the eccentricity between the core and the hammer. Stalling under the action of the spring from the surface of the site, the hammer is moved to interact with the anvil of the core. The impact energy of the hammer is transferred to the core and the surface of the part is branded. 1 ill.

Description

The invention relates to impact devices, can be used for branding and coring products and is an improvement on the known device described in Auth. No. 1646837.

The purpose of the invention is to increase reliability.

The drawing shows a General view of the device, a longitudinal section.

The automatic device for branding comprises a housing 1 with a head 2 consisting of a tip 3 and a sleeve 4. The inner surface of the housing 1 has two cylindrical sections 5 and 6 with different diameters and a conical section 7 connecting them. In the housing 1 there is a force adjustment mechanism 8 impacts, axially spring-loaded core 9 with anvil 10 and firing pin 11. On the core shank 9 there is a working section 12 formed by the difference between the diameters of the core 9 and the anvil 10.

The tip 3 is attached to the housing 1, inside of which the sleeve 4 is placed.

An eccentric chamfer 13 is made on the end face of the bushing 4 facing the striker 11. At the end of the striker 1 there is an annular

a protrusion 14 acting as a contact element.

Automatic device for branding works as follows.

The core 9 is brought to the workpiece 15 until it touches it. As the housing 1 moves towards the part 15, a spring 16 is compressed, which is located between the striker 11 and the impact force control mechanism 8. With further movement of the housing 1, its conical section 7, connecting the cylindrical sections 5 and 6, interacts with the annular protrusion 14 of the hammer 11. The hammer 11 is displaced along the working section 12, choosing the eccentricity between the core 9 and the hammer 11. Disruption, under the action of the spring 16 from the surface of the working section 12, the striker 11 is moved to interact with the anvil 10 of the core 9. The impact energy of the striker 11 is transmitted to the core 9 and the surface of the part 15 is stamped. The magnitude of the impact is regulated by the impact force control mechanism 8.

The core 9 is returned to its initial position by withdrawing the housing 1 from the part 15. Under the action of the spring 17, the pressure N | Yu SO

the core 9 to the sleeve 4, the core 9 extends from it. The firing pin 11 continues to move along with the core 9 until it contacts the annular eccentric chamfer 13. When the annular protrusion 14 comes into contact with the eccentric chamfer 13, the core 9 is finally extended from the hole 18 of the firing pin 11.

At the point where the end face of the striker 11 is higher than the end of the core 9, the striker 11 is displaced along the annular chamfer 14 until the side wall of the hole 18c contacts the anvil 10.

The automatic branding device is ready for use again.

Claims (1)

SUMMARY OF THE INVENTION Automatic branding device No. 1646837. characterized by the fact that, in order to increase reliability, the head is made of two parts, the first part is mounted on the end of the body and covers the firing pin, and the second part is mounted coaxially and faces an eccentric bevel to the firing pin.
