Abstract

The invention discloses a machining process for the connection of a rod on a metal substrate. The machining steps comprise (1) machining external threads on the connecting end of the rod; (2) machining a small hole in the metal substrate by using a drill bit device, wherein the inner diameter of the small hole is less than half of the outer diameters of the external threads; (3) heating the periphery of the small hole by adopting heating equipment, and controlling the heating temperature to be between 800 and 900 degrees; (4) selecting corresponding extrusion equipment to extrude and thicken the heated small hole to form a base hole, wherein the inner diameter of the base hole is larger than the inner diameter of the small hole and smaller than the outer diameter of the external threads, and the front and rear ends of the base hole protrude from the front and rear surfaces of the metal substrate correspondingly; (5) machining internal threads, matched with the external threads, on theinner side wall of the base hole; and (6) connecting the connecting end of the rod with the base hole in a threaded mode. By means of the mode, the machining process can improve the connection strength between the rod and a plate.

Description

technical field [0001] The invention relates to the technical field of rod and plate fixed connection processing, in particular to a processing technology for rod connection on a metal substrate. Background technique [0002] Most of the existing rods and plates are connected by welding or riveting. Although the processing is simple and convenient, because the cross-sectional area of ​​the rod is small, the connection strength between the rod and the plate is not high, and the force that can be endured is limited. , In the case of long-term stress or when subjected to a large force, the connection between the rod and the plate is easy to break. [0003] Especially in the embedded parts of the curtain wall (the embedded parts of the curtain wall include the embedded board and the embedded nail, and the fixed connection between the embedded nail and the embedded board), the connection strength between the embedded nail and the embedded board is required to be higher. The exis...
