The head is safety. Device and principle of work.
1 – case; 2 – plug; 3 – balls; 4 – spring; 5 – lead; 6 – balls/; 7 – springs are dish - shaped; 8 – ring; 9 – a sleeve 10 – a nut; 11 – the ring is castle; 12 – cap; 13 – washer
- The tap is established in a square opening of the case 1 and the plug 2. - The clip of a tap is made by balls 3 when moving the plug 2 by a spring 4. - The torque to the case 1 from the thread - cutting boss is transmitted by a lead 5 through the balls 6 which are drawn in by a ring 8 and dish - shaped springs 7 in case holes. Adjustment of torque is provided with change of size of deformation of dish - shaped springs 7 at rotation of a nut 10.
The head safety is delivered with the adjusted torque providing cutting of the carving specified on a head in steel 45, 153 … 203 HB in accordance with GOST 1050 - 88.
Torque size for others staly is defined experimentally and is regulated by rotation of a nut 10, according to the passport of a product.
Order of control and work:
When cutting a carving in stalyakh with the mechanical properties different from steel 45, it is necessary to execute the following:
- by a calculation or ex - remental method to determine the moment of cutting of Nanometer in this steel (by a dynamometer key) by a necessary tap.
- to remove a castle ring and to make control of torque rotation of a nut clockwise for increase in torque. Control of a head on torque is made by a dynamometer key and the special mandrel recorded instead of a tap. After control of a head to record a nut a ring castle.
- after control the head is ready for operation and correctly adjusted head has to provide smooth cutting with a carving tap, at a tap emphasis in a bottom of a deaf opening emergence of a crash in a head signals about the termination of rotation of a tap.
- when cutting a carving with a small step the size of torque is determined by a formula:
