Abstract
The invention provides chemical composition and a manufacture method of a special seamless tube for high-temperature heating of a duplicator. While compared with a conventional duplicator heating material, the special seamless tube which is produced with the method and used for high-temperature heating of the duplicator has excellent high-temperature mechanical properties and high heating speed, has higher tensile strength and longer service life under the long-time high-temperature operating conditions of the duplicator and can be conveniently used in any season. The seamless alloy tube has relatively higher tensile strength at the high temperature through adjustment of chemical components of the seamless tube; and a core through rod and a needle head penetrate through the middle of an aluminum rod, and then, a backward extrusion technology for extrusion is used for producing the seamless tube, so that conditions that a welding line exists due to forward extrusion and the seamless tube is prone to cracking due to existence of the welding line are avoided.
Description
Technical field
The present invention relates to duplicating machine heating material, relate in particular to the special-purpose seamless tube of duplicating machine heat.
Background technology
Duplicating machine is the equipment of the autotype that obtains etc. doubly, zoom in or out of the original copy from writing, draw or printing.The speed that duplicating machine duplicates is fast, easy and simple to handle, compares with traditional font printing, paraffin paper mimeograph, offset printing etc. without through intermediate meanses such as other plate-making, and can be directly from original copy acquisition autotype.The invention of duplicating machine and use greatly facilitate people's routine office work life, have improved people's working efficiency, have become the requisite instrument of current office.Duplicating machine has the working process of heat in the process of duplicating, and seamless tube is the working part of core in high-temperature heating process.Special-purpose its material of seamless tube of the most of duplicating machine heat of China be take 6063 aluminium alloys as main, product mainly be take forward extrusion product out as main, because forward extrusion is directly to adopt extrusion machine to carry out jumping-up extruding, there is no punching bar, aluminium bar flows out by mould, so form seam in the outer meeting of mould, there is defect to a certain degree, sometimes even can crack.Adopt this kind of method in the making processes of heat seamless tube, to be bound to form seam line, because the existence of seam line can cause easily cracking under the working conditions of high temperature, thereby greatly affect the practical life of photocopying effect and this kind of seamless tube, cause the routine maintenance cost of duplicating machine to increase, bring very big inconvenience to people's routine office work.
Summary of the invention
The object of the invention is to overcome the existence due to seam line in prior art and cause the deficiency easily cracking under the working conditions of high temperature, the special-purpose seamless tube chemical composition of a kind of duplicating machine heat and manufacture method thereof are provided.The method is produced the special-purpose seamless tube of duplicating machine heat and is had good mechanical behavior under high temperature and the rate of heating being exceedingly fast than traditional duplicating machine heating material.Can guarantee that duplicating machine, under long-time hot operation condition, possesses higher tensile strength, there is longer work-ing life, and convenient in any use in season.The present invention, by adjusting seamless tube chemical composition, makes this alloy seamless pipe tensile strength at high temperature relatively high; By adopting punching bar and syringe needle to penetrate in the middle of aluminium bar, the reverse extrusion technology of then pushing, produces seamless tube, has avoided seam line that forward extrusion occurs and has easily caused the generation of crackle because of the existence of seam line.
The technical solution adopted in the present invention is as follows:
The special-purpose seamless tube chemical constitution of duplicating machine heat of the present invention proportioning is: Si:< 0.3; Mg:0.7-1.3; Below Fe:0.4; Cu:0.6-0.8; Mn:0.7-1.1; Cr < 0.1; Ti < 0.10; Zn < 0.10; Be:0.005.
The element that in this alloy, chemical constitution proportioning mainly contains is Mg, Cu, Mn.
The Main Function of various chemical elements is:
(1) in order to reduce the crackle tendency in fusion-casting process, control w(Fe in alloy) > w(Si).
(2) in order to prevent that reverse extrusion seamless tube out from avoiding producing FeMnAl6 metallic compound one para-crystal defect in post annealed process, control w(Fe)+w(Mn) < 1.8%.
(3) increase appropriate Cu content, due to the increase of Cu constituent content, can form Al
2the compounds such as CuMg, are conducive to play precipitation hardened effect, and then put forward heavy alloyed tensile strength.
Adopt seamless tube that alloy that chemical constitution proportioning of the present invention produces makes tensile strength at high temperature relatively high, avoided traditional seamless tube under hot operation condition, easily crack, and the crackle causing because of the existence of seam line.There is good mechanical behavior under high temperature, and the rate of heating being exceedingly fast, can guarantee that duplicating machine, working under hot conditions for a long time, has longer work-ing life, convenient in any use in season.
