After the development spring processing technology?

Spring factory to know that at this stage, mechanical equipment spring production equipment and production processing production line in nc machine tools ( NC) And control computer system ( CNC machining center) The deep breadth and depth of development trend. But with the transition of the new spring raw material and geometry shape, the production processing technology also has a development trend. Spring over the production and processing technical development trend? ( 1) Change spring diameter, defect and stainless steel wire diameter ( Three changes) Spring suspension system to keep no molding deformation processing. Since spring development design trible changers, always choose the Erlenmeyer round steel on the machining center machine production and processing, but the productivity and the price is not ideal. Now change to heating cases according to the compression spring machine, manipulation of the roll rate and tensile strength, get the necessary cone, and with the production and processing of waste heat recovery in heat treatment. ( 2) Hollow flat spring rod choose low carbon boron steel plate welding welding. ( 3) Torsion bar and the use of high purity of 45 steel, the induction hardening have high toughness and a lot of the remaining on the surface of the narrow ground stress, raise fatigue life and relaxation resistance. ( 4) Electronic equipment widely used in most of the leaf spring selects the stamping die and production processing automatic bending forming. At this stage mainly close connection technical development trend of polymer materials. 1, the cold forming process (spring 1) Cold forming process of disposable automation technology ability. Development trend of cold forming machine now to 12 feet. In the ( 0. 3 ~ 14) Mm category of stainless steel wire, mostly in eight claw shape function forming at a time. Forming technology of machinery and equipment development prospects: (1) improve the forming rate, the key development trend is to improve forming rate of machinery and equipment, namely the productivity; (2) according to improve precision of machinery and equipment * and strengthen the actual effect of quenched and tempered treatment to improve equipment performance; (3) improve the length and the laser range finder, forming machine to carry out the automatic feedback control for CNC machining center production and manufacturing process. ( 2) Cold forming technology category. Big wire specifications spring compression spring machine at present stage, larger
specifications at 22 mm, = 2000 mpa, convolute than 5. Diameter, such as the variable diameter or Mlnic - Block spring and axial force of spring cold forming technology still has limitations. 2, spring hot forming process ( 1) Hot forming process rate. In our country at present stage in the ( 9 ~ 25) The forming on mm specifications only hot spring coiling machine, CNC machining center 2 shaft larger
rate per minute 17 items. Compared with capitalism * under difference is very big. ( 2) Big spring hot forming process control ability. Because only 2 axis nc machining center hot spring coiling machine, thus appearance manipulated three orientation effect, less precision is poor; And have no automatic rotation of round controlling and adjusting organization, therefore low hot coil spring forming technology and skills. So the spring precision level and air oxidation surface carburized level is low.
