Cemented carbide thread rolling tools

Used cemented carbide rolling tool includes cemented carbide thread roller and cemented carbide roll plate.

1.cemented carbide thread roller

Often threading tool, die, thread cutter, cutting tool machining external thread, also widely used rolling, rubbing pressure and squeeze the threaded portion forming process using cemented carbide thread roller threaded part of the processing forming is one of the rolling method.

Cemented carbide thread roller teeth withstand impact, squeezing and friction. Chipping cemented carbide roll in the form of wire wheel failure, fatigue spalling and wear. Therefore, carbide thread roller requires a high-strength; high wear resistance and good toughness. Cemented carbide rolling the wire wheel is usually used Cr12MoV steel.

Cemented carbide thread roller generally one to two components, mounted on rolling machine rolling, as shown in a. The two cemented carbide spiral thread rolling wheel the same direction as the direction of the spiral, cemented carbide thread roller thread workpiece thread spiral opposite direction (such as carbide thread roller thread is left-handed, were the workpiece thread is right spin). Cemented carbide thread roller installed in two parallel thread rolling machine spindle (two thread roller end faces should be on the same plane), threaded staggered by half a pitch before the operation should be the correct debugging. Machining the workpiece on the two cemented carbide roll wire wheel support in the middle of the board, two spindle with constant speed rotation, a spindle except itself rotating radial feed movement workpiece gradually under pressure to form a thread conodonts. Stop feeding when processed to a predetermined size, and continue rolling a few laps to fix the outline of the tooth type and tumbling threaded surface. Subsequently, for the movement of cemented carbide thread roller exit, remove the workpiece. Rolling coolant should be used to cool and lubricate cemented carbide rolling wheel and workpiece.

Cemented carbide thread roller thread precision machining, surface roughness generally up Rz3.2μm.

2. Cemented carbide Roll plate

cemented carbide Roll plate is a high-efficiency production workpiece external thread rolling tool. Cemented carbide Roll plate rolling subjected to intense friction, and withstands shock loads and squeeze pressure, failure usually in the form of the teeth wear, pitting, chipping teeth and flaking. Cemented carbide Roll plate commonly used 9SiCr, of Cr12MoV or DC53 steel manufacturing. Figure b cemented carbide thread rolling board. Cemented carbide Roll plate composed of two plates, expanded cemented carbide Roll plate positive thread. An activities cemented carbide Roll plate (also called the moving plate), mounted on the slider vertical reciprocating thread rolling machine; another one is fixed cemented carbide Roll plate (also known as static board), mounted on the thread rolling the machine's work table. Static block has press-in portion, the correction portion and the exit portion. Immediately when the blanks by the press-fitting portion to enter between the two plates to be clamped, with the relative movement of the cemented carbide twist wire board, forcing the workpiece rotation, thus rolling a thread, and in the exit portion slipped, to complete the thread forming the whole process. High speed due to the relative motion of two cemented carbide Roll plate, thread forming process is only a very short period of time, so the production is very efficient, especially suitable for the mass production of standard parts.

Cemented carbide Roll plate generally refers to the flat-shaped Roll plate processing thread is a round trip. Arc Roll plate is the thread of continuity feeding roll system, it can save the flat cemented carbide Roll plate and from emptying time. Flat cemented carbide twist wire board due to the stroke limit, generally only used the thread following the machining diameter of 24mm, and because the press-in portion of the thread forming process and the correction part of the length limitations, the workpiece forming process time short pressure workpiece roundness error, not suitable for processing thin-walled parts.
