The anchorage device of the key part needs 2 prestressed components each time a group of prestressed components is pre-tensioned, and the requirement amount is very large due to one-time use, but a large lifting space is left on the current machining efficiency, so that the part is machined in the industry at present.
The anchorage device is a product which is shaped like honeycomb briquette after processing a medium carbon steel cylinder with a specific size, and a plurality of uniformly distributed conical holes are arranged on the same plane of the anchorage device. The existing processing technology is to saw round steel, turn two end faces and an excircle through a lathe, drill a hole by a drilling machine, and ream a taper hole by the drilling machine. The processing modes are basically classified into the following three types.
Firstly, the method comprises the following steps: two end faces and an excircle are turned by a lathe, a front twist straight drill combined conical stepped drill is used on a vertical drilling machine, manual indexing is performed, a bottom hole is formed by drilling downwards from the end face of a steel cylinder, and reaming of the conical hole is completed by a radial drilling machine.
II, secondly: the two end surfaces and the excircle are turned by a lathe, a front twist straight drill is used on a numerical control vertical drilling machine to combine a conical stepped drill, the automatic indexing is performed, the drill is drilled downwards from the end surface of the steel cylinder to form a bottom hole, and the reaming of the conical hole is completed by a radial drilling machine.
Thirdly, the method comprises the following steps: two end faces and an excircle are turned by a lathe, a front twist straight drill is used on a vertical machining center to combine a conical stepped drill, automatic indexing is performed, a bottom hole is formed by drilling downwards from the end face of a steel cylinder, and automatic tool changing and reaming of a conical hole are completed by a tool magazine.
