The mechanical part of the automatic spring pulling and pressing machine can draw on the structure and appearance of the domestic and foreign manufacturers and strictly according to the standard of the National Machinery Department, which is different from the ordinary electronic tension test machine of the domestic manufacturers, and the machining precision of the mechanical parts is far higher than the electronic tension test machine.

The program control part is independently and independently developed by Ji'nan platinum reference, which is suitable for the detection of various springs. The control program has simple interface, complete functions, simple and easy to learn, and easy to operate. A free upgrade service can be provided. The mechanical part of the automatic spring pulling and pressing machine can draw on the structure and appearance of the domestic and foreign manufacturers and strictly according to the standard of the National Machinery Department, which is different from the ordinary electronic tension test machine of the domestic manufacturers, and the machining precision of the mechanical parts is far higher than the electronic tension test machine.

Resolution: the minimum indication difference that the indicating device can effectively distinguish from the automatic spring tension tester.

Remaining height: the height of the object after the deformation of the spring under the action of external force is expressed by H.

Deformation: the relative displacement of the spring in the direction of load acting on the spring tension tester. The height of deformation (free height residual height) is expressed by delta H.

Spring stiffness: the load or torque required to cause the spring to generate unit length (horny) deformation. The K= (F2-F1) / (H2-H1) unit is expressed in N/mm.
