Abstract
A method for forming dual-conic sleeve barrel for reinforcing bars includes heating solid raw stock, drilling with small-diameter rotary die, and forming dual cones (including outer periphery) with conic die. It is possible to cut long solid raw stock to defined length after it is drilled and then to forming dual cones. Its advantages include simple process, high productivity and quality of finished products.
Description
The present invention is a kind of processing method of metal, particularly a kind of manufacturing process that is used for two reinforcing bars are docked to double-cone reinforced bar sleeve together.
In the prior art method for metal working, turning, cutting thread, boring, cut-out operation have been common process, and the double-cone reinforced bar sleeve method of attachment is not used in the prior art as yet, so its processing method still belongs to blank.
The objective of the invention is to fill up above-mentioned blank part of the prior art, and a kind of shaping method of double-cone reinforced bar sleeve is provided.
Technical solution of the present invention is: to real core blank heating, use the perforation of minor diameter rotary die then earlier, re-use the prod cast tool and carry out double tapered (comprising cylindrical) shaping.Can also adopt earlier the real core blank of long root is bored a hole, reshape double tapered after cutting off one by one.
The advantage that the present invention is had compared to existing technology is: technology is simple, efficient is high, and the double-cone reinforced bar quality of shaping is good, cost is low.
This accompanying drawing is an of the present invention pair of dimension reinforced bar sleeve.
Provide embodiment below the present invention: to real core blank heating, use the perforation of minor diameter rotary die then earlier, re-use the prod cast tool and carry out tapering (comprising cylindrical) shaping.Can also adopt earlier the real core blank of long root is bored a hole, reshape double tapered after cutting off one by one.Can use for the shaping double-cone reinforced bar sleeve.
Claims (2)
1, a kind of shaping method of double-cone reinforced bar sleeve comprises turning, boring, cutting thread, it is characterized in that earlier real core blank being heated, and uses the perforation of minor diameter rotary die then, re-uses the prod cast tool and carries out double tapered (comprising cylindrical) shaping.
2, according to the shaping method of double-cone reinforced bar sleeve described in the claim 1, it is characterized in that adopting earlier the real core blank of long root is bored a hole, reshape double tapered after cutting off one by one.
