One-time forging process and equipment for prestressed porous anchors

Abstract

The invention discloses a novel one-time forging forming process and equipment for a prestressed multi-hole anchorage device. The novel one-time forging forming process comprises the steps that a blank is heated to the forging temperature and accurately put into the center of a jacked drain cap through a feeding manipulator, the drain cap falls down along with the movement of an ejection device, and the blank enters a lower die; an upper die is rapidly pressed through a movable cross beam of the equipment, the movable cross beam is controlled to reach a lower closed position through a proximity switch, and thus the one-time punching process can be completed; after punching is completed, the movable cross beam is rapidly lifted, a die unloading plate is pressed through a belleville spring at the same time, and the effects that a forging is left in the lower die, and punching heads and the forging are separated are ensured; and then the forging is ejected from the lower die through the ejection device, the punched forging is taken out and placed onto a conveying belt through a discharging manipulator and is fed into a quenching pool, and the quenching process is completed through waste heat of the forging. According to the novel one-time forging forming process and equipment for the prestressed multi-hole anchorage device, multiple holes of the multi-hole anchorage device are subjected to one-time punching forming through the forging method, especially the taper hole parts can be directly formed, the reaming process is reduced, personnel is saved, the equipment investment is reduced, and the product performance is improved.

Description

Technical field: [0001] The invention relates to a method for making a prestressed porous anchor, in particular to a prestressed porous anchor one-time forging forming process and equipment. Background technique: [0002] With the development of prestressing technology, the proportion of prestressed anchors used in prestressed engineering is increasing. Anchorages for concrete prestressed tension are generally used in bridge construction and are suitable for engineering construction. After the pre-installation and positioning, concrete is poured and buried at both ends of the concrete, that is, the two ends of the bellows, which are the end faces set for the stability of the jack during tension. Prestressed anchors are widely used in highway bridges, railway bridges, urban overpasses, urban light rail, high-rise buildings, water conservancy and hydropower dams, port terminals, rock mass slope protection anchorage, foundation reinforcement, tunnel mine roof anchorage, prestr...

AI Technical Summary

Problems solved by technology

[0003]At present, the main production process of domestic prestressed anchorage manufacturers is to use round bar material for a large number of machining (sawing, turning, grinding, drilling, rough reaming, Fine reaming and milling) can be completed. The whole production process has many processing procedures, large amount of machining, low material utilization rate, and high production cost. Fine reaming and other processes can only be realized, because of the particular size of the product, special custom-made special tools are required, and the production cost is relatively high
