  High precision cold drawn tube is a new high-tech energy-saving product. In recent years, using this technology to produce precision steel tube has been widely used in domestic hydraulic, pneumatic cylinder, coal mine support (prop), oil pump pipe, Jack and other manufacturing fields. Precision cold-drawn steel pipes with high precision promote the use of steel, improve processing efficiency, save energy, reduce investment in hydraulic cylinders and cylinder processing equipment is important. Cold drawing method: Comparing with the traditional cutting technology, the production of high precision cold drawing pipe-hydraulic cylinder has the following characteristics: (1) High production efficiency: The traditional method of producing cylinders with diameter of 420 mm and length of 12 meters is 154 hours, and the cold drawing method only takes 4 minutes to produce. (2) Real high speed: Boring of the boring head and play a guiding role in the cutting process, billet tube due to self-w

  Step 1: Inspection In the initial inspection, the rod is assessed to evaluate its condition ahead of the chroming process. Here the inspector will note any evidence of corrosion, pitting, marring, damage, cracking or flaking of the material. Presence of these phenomena will be taken into account and may influence the decisions taken at various steps along the re-chroming process. Step 2: Grinding & Stripping Before new chrome can be applied, the old material must be removed. However, this must be done in such a way to preserve the steel underneath and without reducing the diameter of the rod itself. Doing so would result in a rod that exceeds cylinder tolerances. There are two methods for removing this material. These are: grinding and stripping. Electrolytic Stripping: During stripping, the rod is placed in a reverse-electrolysis tank. This process is essentially the opposite of electrolytic plating. Whereas chrome plating applies a positive current to a chrome solution - w

  How to prevent the corrosion of chrome plated bar? Prevention of corrosion extends beyond just the manufacture of the chrome plated bar. Handling and storage of the chrome bar can dramatically affect corrosion resistance. Ensure the protective fiber tubing does not get moist or wet with water or other contaminants. Remove any wet fiber tubes from rods or tubes and dry the rods or tubes immediately. When transporting chrome plated rods or tubes between operations, do not leave them in contact with surfaces that may contain coolants, lubricants, cleaning agents, or other sulfur or chlorine containing surfaces. Do not transport in loose quantities that can contact one another. Point impacts can damage the integrity of the chrome plate and eliminate corrosion resistance. Do not leave rods or tubes unprotected between operations or during transfer between buildings, if the transfer is over an extended period of time. A light oil film should be applied. Do not place unprotected chro

  Hardness measurement of  hydraulic cylinder piston rod  is usually divided into two kinds: destructive measurement and non-destructive measurement. Nondestructive measurements are less damaging and cannot be completely damaged. This injury is fatal in comparison to a piston rod, and therefore can only be done by destructive measurements. Piston rods sometimes deform after nitriding. At this time, has reached the finished size requirements, and the surface hardness is very high. It cannot be refined by processing methods. Only the straightening method can be used to control the deformation at a reasonable level. In the range. Commonly used pressure straightener, whether hot or cold, its straightening accuracy is artificially affected, can reach 1 to 2 mm. Usually, the bending deformation of some products after the nitriding of the piston rod is 0.1 to 0.3mm, so the deformation is very small and can not meet the requirements of the pressure correction machine. Bending and percussion vi

  ck45   hard chrome plated bar   has very good machinability, similar to 1045 uncoated bar. Machining however should commence beneath the chrome plating, or at the unchromed surface at the end of the bar. ck45 is a medium tensile carbon steel supplied in the cold drawn or turned, precision ground, polished, chrome plated and final polished condition, with a typical base metal tensile strength of 670 – 800 Mpa, plus a typical hard chrome plated surface hardness of HV 1000 – 1150. Characterised by an extremely smooth surface finish with excellent wear and corrosion resistance, coupled with a base material giving good strength and impact properties, plus good machinability and reasonable weldability. ck45 hard chrome plated bar is used extensively by the hydraulic and pneumatic industries, and is employed by other industry sectors for a wide range of applications.
