Embodiment 1

[0035] Example 1, such as figure 1 , as shown in 3, a processing device for a hollow bolt body, including a feeder 2, a cold forging machine 3 that is dragged by the feeder 2 and the blank pipe 1 passes through successively, an induction furnace 4, a thread rolling mill 5 and a support frame 6, the above-mentioned The equipment is controlled by a control system; in the frame 31 of the cold forging machine 3, a rotating ring I33 and a rotating ring II35 located inside the rotating ring I33 are embedded, and a plurality of cams 32 are installed on the circumference of the rotating ring I33, A plurality of hammer blocks 34 movable along the radial direction of the rotating ring II 35 are installed on the circumference of the rotating ring II 35 .

[0036] The processing of the hollow anchor rod body in the prior art adopts the hot rolling reduction process, and the devices used include feeder-intermediate frequency heating equipment-three-axis rolling mill-thread rolling mill-sup...

Embodiment 2

[0048] Embodiment 2, the difference between this embodiment and embodiment 1 is: as Figure 7 , the feeder 2 includes three driving wheels 25 driven by a continuously variable speed motor, and the three driving wheels 25 surround the outside of the waste pipe 1 .

[0049] The process of variable-speed feeding of waste pipes is as follows: waste pipe 1 is put into feeder 2, and feeder 2 uses three driving wheels 25 to hold waste pipe 1 tightly and cross-rotate to generate traction to realize feeding. Feeding speed.

Abstract

The invention discloses a machining device for a hollow anchor rod body. The machining device comprises a feeding machine, a pierced billet is pulled by the feeding machine to feed into a supporting rack after sequentially passing through a cold forging machine, an induction furnace and a thread rolling machine, and the feeding machine, the cold forging machine, the induction furnace and the thread rolling machine are all controlled by control systems. The invention further discloses a machining process for the hollow anchor rod body, the machining process comprises the following steps of variable speed feeding of the pierced billet, cold forging reducing, induction heating and thread hot rolling forming. In the whole process of the machining process, the control systems of all equipment are on one panel, and the operation is convenient; and the whole feeding process is adjusted by adopting stepless speed changing, and the adjustment accuracy is high. The feeding process of the piercedbillet can be completed manually and automatically, manual operation is not required in the falling process, and the degree of automation is high.

Description

technical field [0001] The invention relates to the technical field of manufacturing a hollow anchor rod body, in particular to a processing device and a processing technology for a hollow anchor rod body. Background technique [0002] As a technical means of geotechnical engineering reinforcement, hollow bolts have been widely used in tunnels, mines, shafts and civil engineering, and the consumption is huge. Hollow bolts are usually composed of a rod body, a tray, a nut, a grout plug, and some also include an anchor head and a connecting sleeve. The most important of which is the production of the rod body and the rod body. [0003] The hot rolling reduction process used in the processing of the hollow bolt body in the prior art, the main equipment used is the feeder-intermediate frequency heating equipment-three-axis rolling mill-thread rolling mill-support rack, the method of processing the hollow bolt body is to use Feed-medium frequency heating-diameter reduction-thre...
