What are the advantages of cold rolled lead screw?

As an efficient,chip free processing technology,cold rolling forming is a model of cleaner production,in the "green revolution","circular economy","high efficiency manufacturing" concept of the promotion of cold rolling forming in the rolling functional parts industry has been rapid development.

The cold-rolling forming process of trapezoidal lead screw thread is the process of plastic deformation of metal round bar material under the action of high pressure radial force.Under the action of external force,the metal grain of the metal bar material slides along the contour of the roll,and the metal fiber is distributed continuously according to the tooth shape of the roll.And cutting processing(including: turning,milling,grinding) metal fibers are cut.Cold rolled lead screw has the following characteristics:

(1) High production efficiency,short lead time,easy to achieve production automation.

(2) Energy saving, material utilization can reach 80-90%.

(3) High mechanical strength,long fatigue life.The mechanical properties and life of the product mainly depend on the hardness of the material(chemical composition,elastic modulus, etc.),the depth of the hardened layer,and the density of the internal organization.The raceway surface of the cold rolled trapezoid lead screw thread is rolled under high pressure,so its internal organization is more compact,and the metal fiber is continuously distributed along the raceway surface.Therefore,the mechanical strength of the product material is greatly improved,and the fatigue life can be increased by about 30%.

(4) The surface roughness of the thread raceway surface is good,and the thread and tooth surface burns easily caused by thread grinding are avoided.The thread raceway after cold rolling is polished and surface treated,which is more conducive to extending the working life and running flexibility of the product;

(5) Cold rolling technology is a pleasant process,and the environmental pollution of the production site is far lower than that of grinding processing;

The application fields of cold rolling trapezoidal screw include:electronic equipment,CNC machine tools,glass machinery,woodworking machinery,packaging machinery,printing machinery,engraving machine,engraving and milling machine,drilling machine,test equipment,automobile steering gear,airport boarding bridge,reservoir gate opening and closing mechanism, ship control console,balance crane,lifting device and so on.
