Abstract

The invention relates to metal working and can be used for magnetic treatment of a cutting tool. The purpose of the invention is the invention relates to metal working and can be used for the magnetic treatment of a cutting tool. The purpose of the invention is to increase productivity, reduce energy consumption and metal construction. Figure 1 shows the device raz.rez. - The device for magnetic treatment of the cutting tool contains a co-g lenoid 1 with cores 2, an armored magnetic circuit 3 with a cantilever protrusion 4, an element 5 for accommodating the tool 6 to be machined, performed as a tight non-working part of the sleeve 6 having a reliable magnetic connection with the magnetic core 3 in its console. protrusion 4. Element 5 is included in the opening of productivity, reduction of energy consumption. and metal consumption of the structure due to elimination of magnetic flux dispersion in space. The device contains a solenoid 1c core 2, a magnetic core 3 of armor type with a cantilever protrusion 4, an element 5 for accommodating the tool to be machined 6. Element 5 is injected into the opening of the solenoid 1 so that between its end face and the end face of core 2 there is an axial gap, the size of which is length 1 of the machined area of the tool. 1 il. There is a solenoid 1 so that between it: the end face and the end face of the core 2 there is an axial gap, the value of which is equal to the length of the 1.treated tool section. The device works as follows. The magnetic flux induced in the magnetic system by the solenoid 1 when connected to the source of electric current flows through the core 2, the magnetic circuit 3 and closes through the portion of the tool 6 to be processed. The cantilever protrusion 4 of the magnetic core 3 ensures good centering of the element 5 for holding the tool 6, and also reduces the resistance to the passage of magnetic flux in the movable connection between the magnetic core 3 and the element 5.

Description

3 1

Element 5, in turn, tightly covers the non-working part of the tool 6 and thereby facilitates the passage of magnetic flux to it.

This design of the device provides a very high magnetic field strength at the machined area 1 of tool 6 and around it, which reduces the cycle time of the surface. workouts and increases the reliability of the results
