Problems solved by technology
At the same time, because the forging and upsetting technology at the end of the rod body is restricted by forging, the length of the thread at the end of the rod body of the steel tie rod is limited, which greatly limits the adjustment range of the steel tie rod product.
And because the raw material of the steel tie rod body is hot-rolled round steel, the maximum production length of the domestic steel factory is 12m, which also leads to the maximum length of the steel tie rod body not exceeding 12m

The invention discloses a forming method of a steel pull rod body. The forming method of the steel pull rod body comprises the following steps of manufacturing a rod body blank of a steel pull rod; transferring the rod body blank to a conveyor; heating the rod body blank; carrying out thermoplastic molding on the rod body blank; and performing heat treatment on the rod body blank, disassembling the rod body blank and entering the next process. The forming method of the steel pull rod body is high in automation degree and suitable for batch production of the steel pull rod body, the length of the steel pull rod body is increased, and steel pull rod products of various specifications and length dimensions are met; and the problem that threads of a steel pull rod product in the upsetting process are short is solved, the comprehensive mechanical property of the steel pull rod body is improved, and the application range of the equal-strength steel pull rod product is further expanded.
Description
technical field [0001] The invention relates to the technical field of steel tie rod manufacturing, in particular to a forming method of a steel tie rod body. Background technique [0002] Steel tie rod products have been widely used in building structure projects. In some application environments of steel tie rod products, such as suspension bridge anchor tie rods, anchorage connector connection tie rods, etc., steel tie rod products are required to have longer threads for control and adjustment. The length of the cable. However, at present, the end of the rod body of the steel tie rod product adopts forging and upsetting technology to realize the equal-strength design of the rod body. At the same time, because the forging and upsetting technology at the end of the rod body is restricted by forging, the length of the thread at the end of the rod body of the steel tie rod is limited, which greatly limits the adjustment range of the steel tie rod product. And because the ra...
