Embodiment Construction
[0016] The method of the invention is suitable for detecting the rigidity of lead-calcium alloy grids or lead-antimony alloy grids used in lead-acid storage batteries. The lead-calcium alloy grid or the lead-antimony alloy grid needs to be effectively hardened after casting. The hardening method can be hardened in a drying room: temperature: 60±10°C, time: 16-24h, or natural hardening for more than 1 week. The rigidity of the hardened grid is detected by the method of the present invention, qualified products enter the plate coating process, and unqualified products are subjected to effective hardening again.
[0017] For the convenience of operation, the present invention designs a device for detecting grid stiffness. see figure 1 The device of the present invention comprises a base 8, a support frame 4, a scale 6, a measuring ruler 5 and a guide rail 7, the guide rail is fixed on the base, and the two support frames are positioned on the guide rails and can move along the g...
