High-Speed Cold Nut Former are used for producing different kinds of self-tapping screws, rivets, hinge pins, and special parts in the field of the fastener industry. Because of the advantage of the cold forging equipment itself and the superiority of the cold forging technique, the  Five Stations High-Speed Cold Nut Former  al

 Z41 series are Chinese-made cold former. Z41 series using cold drawn disk or bar to form bright hex nut blank, and tap to obtain bright hex nut. Z41 series is all of the horizontal types with the horizontal multistage arrangement. The full process is carried out automatically from feeding, cutting, pushing, and clamping, to cold heading. It features precise reliable positioning, easy operation, regulation, maintenance, assembling, and energy saving. It is the ideal equipment for reliably producing quality non-standard irregularly shaped nuts. Hot sales Z41 series Nut Cold Former are Z41-20 (M16-M20), Z41-24 (M20-M24), Z41-27 (M24-M27), Z41-30 (M30), and Z41-33 (M33).

Introduction The valve stem seals keep the valve stem lubricated as it slides within the valve guide. Low oil levels cause stems and guides to wear out. Increased oil consumption can lead to carbon buildup, causing valve seat damage and an early valve grind. Oil consumption may also be affected by defective valve stem seals. Engine valve stem seal Parts structure of valve group 1. The composition of the valve group Valve composition 9-Valve lock clip  10-Valve spring retrieve  11-Valve spring  12-Valve stem seal  13-Valve guide  2. Valve Material Medium carbon alloy steel for intake valve, heat-resistant alloy steel for exhaust valve        Intake valve 300℃—400℃        Exhaust valve 780℃—980℃ Some engine exhaust valve stems are filled with liquid sodium, and alloys are surfacing on the sealing cone and tail to prevent wear and tear. Valve material Manufacturing  Valve The valve is divided into two types: intake valve and exhaust valve. Its function is to seal the intake and ex

  Introduction to cold heading process characteristics The cold heading process is suitable for iron, copper, stainless steel, alloy steel, titanium alloy, aluminum and other materials for cold heading and cold extrusion forming (extrusion, backward extrusion, and composite extrusion). There are various sizes of parts it can make, such as inside and outside hexagon screws, flange screws, hollow, solid special-shaped parts. Mostly used for producing complex parts for aerospace, railway, shipping, automobile, wind power, and other industries. It is a kind of efficient automated production method with many properties and multiple processes. Cold heading has the following advantages: 1. Cold heading at room temperature will produce a workpiece surface with high brightness, high precision and superior strength properties. 2. By using cold heading saves raw material, reduces labor costs, and avoids repeated investments in other machine tools. 3. The cold heading process utilizes mo
