Anchor clipper through hole type workblank cold pressing technique

Abstract

The invention relates to an anchorage device clamping piece through-hole type blank cold flow pressing process used in a pre-stressed anchorage device system, which is characterized in that after a round bar and a stock are chosen, the following steps are performed in sequence: discharging, shot blasting treatment, phosphorizing and saponifying treatment, performing, normalizing treatment, shot blasting treatment, phosphorizing and saponifying treatment, extrusion forming, punching forming, shot blasting treatment, phosphorizing and saponifying treatment and extrusion forming, the anchorage device clamping piece through-hole type blank similar to the finished product clamping piece can be prepared out by adopting the steps. The invention has the advantages that the availability and the saving rate of material are high; the machine processing amount is greatly reduced; the compactness of the clamping piece is increased.

Description

technical field [0001] The invention relates to a cold extrusion process for a through-hole blank of an anchor clip used in a prestressed anchor system. Background technique [0002] The prestressed anchor clip is the most numerous part in the prestressed anchor system, and it is also the part with the largest production volume of each prestressed anchor manufacturer. So far, the prestressed anchor manufacturers have used the most Blank, one is the round bar blank blanked by the round steel band saw, the blank is used to produce the clip, the machining volume is large, the material utilization rate is low, and the cost of the clip is high; the other is the clip whose shape is similar to the finished clip Compared with the former, the use of this blank to produce clips reduces the amount of machining, greatly increases the utilization rate of materials, and reduces the cost of clips. The clip is similar, and its inner hole needs to be processed by multiple machining such as ...

[0002] The prestressed anchor clip is the most numerous part in the prestressed anchor system, and it is also the part with the largest production volume of each prestressed anchor manufacturer. So far, the prestressed anchor manufacturers have used the most Blank, one is the round bar blank blanked by the round steel band saw, the blank is used to produce the clip, the machining volume is large, the material utilization rate is low, and the cost of the clip is high; the other is the clip whose shape is similar to the finished clip Compared with the former, the use of this blank to produce clips reduces the amount of machining, greatly increases the utilization rate of materials, and reduces the cost of clips. The clip is similar, and its inner hole needs to be processed by multiple machining such as drilling. Therefore, in order to further improve the material utilization rate of the clip production, reduce the amount of machining, and greatly reduce the production cost of the finished clip, it is necessary to further improve the clip The utilization rate of production materials reduces the amount of machining and greatly reduces the production cost of finished clips. It is necessary to develop a through-hole blank for clips that is similar in shape and inner hole to the finished clips.
