The invention discloses a reshaping method for hot-extrusion through holes of a working clip in a forging mode. The reshaping method is characterized by comprising an upper molding board, a lower molding board and a pulling plate, wherein a mould handle is mounted on the upper molding board; a convex mould is mounted on the mould handle; two unloading rods are mounted on the lower molding board; unloading plates are mounted on the unloading rods; springs in the state of compression are arranged on the unloading rods between the unloading plates and the lower molding board in a sleeving mode; convex mould sleeves are mounted on the unloading plates; and a concave mould matched with the convex mould is further mounted on the lower molding board. The convex mould and the convex mould sleeve are centered in a matched mode and enter the concave mould for being re-shaped after being pierced, so that products are prevented from offsetting, height of the products can be fixed after being regulated, and reshaped workpieces are guaranteed to reach process requirements; the reshaped convex mould drives the workpieces to ascend, and the convex mould and the convex mould sleeve are separated to complete unloading after the workpieces reach set positions; and compared with an existing process, the forming method has the beneficial effects of saving consumption of raw materials, reducing machining processes and achieving the purpose of reducing cost by about 20%.
Description
technical field [0001] The invention relates to a die used in a forging process, in particular to a shaping method for hot-extruding a through hole of a forging work clip. Background technique [0002] With the development of prestressing technology, the proportion of clip anchors in prestressing engineering is increasing, and the amount is increasing sharply. The most important and largest amount of clip anchors is the anchor clip. The anchor clip is used to clamp the prestressed tendon when anchoring the prestressed steel bar of the prestressed concrete member. It is widely used in various bridges, roads, high-rise buildings and other building constructions. At present, the traditional process of producing anchor clips by various prestressed manufacturers is to use round bar material, and then split the end face, turn the outer round hole, drill the hole, finish the inner hole, process the inner hole taper, tap the inner thread, and turn the outer taper , cutting, heat tr...
