The second overflow valve 24 is provided between the rod chamber of the hydraulic jack 14 of hydraulic jack 4 and second, when pressure exceedes setting pressure, the
One overflow valve 20 and the second overflow valve 24 begin to off-load, allow hydraulic oil directly to flow back to hydraulic oil container 16, avoid in hydraulic circuit
Hypertonia, serve protective effect.In order to reduce the temperature of hydraulic oil, also set on the return line of usual hydraulic oil container 16
It is equipped with air cooler 28.
When the foundation bolt forming machine of the present invention carries out real work, its operating process and process flow are retouched in detail
State for：
As Fig. 1 and Fig. 2 are jointly shown, first clamper 29 and second clamper 30 respectively press from both sides reinforcing bar blank
Firmly, then under the active force of the 5th hydraulic jack 3004, second clamper 30 is again along the reinforcing bar blank conveying side
To movement, because the chucking power of two the 3rd hydraulic jacks 2902 is more than the chucking power of two the 4th hydraulic jacks 3002,
While second clamper 30 moves along the reinforcing bar blank conveying direction, first clamper 29 clamps the steel
Muscle blank is motionless, and the reinforcing bar blank slides in the second clamping cavity of second clamper 30, is formed similar cold
The alignment of technique is pulled out, after the completion of alignment, first clamper 29 unclamps the reinforcing bar blank, and second clamper 30 is clamped
The reinforcing bar blank continues to convey toward downstream, delivers in the charging gap of the charging two pairs of rollers 6, and the charging two pairs of rollers 6 hold
The downstream transport of reinforcing bar blank 9, when the end of the reinforcing bar blank 9 cross first actuating arm 7 and close to it is described into
During core bar 5, first hydraulic motor 17 and second hydraulic motor 18 while fuel feeding, first hydraulic jack 4
Piston rod stretches out, and the rack 3 drives the gear 2 to start to rotate, and drives first actuating arm 7 and second actuating arm
8 counter-clockwise swings, first actuating arm 7 first bend the reinforcing bar blank 9 along the shaping core bar 5, and with described
The rotation of gear 2 continues to convey with the reinforcing bar blank 9, and first actuating arm 7 continues to roll the reinforcing bar blank 9, institute
State the second actuating arm 8 also gradually to contact and roll with the reinforcing bar blank 9, when the piston rod of first hydraulic jack 4 extends
During to extreme position, the reinforcing bar blank 9 is just bent shaping, and now second hydraulic jack 14 drives the shaping core bar
5 slide vertically, by it is described shaping core bar 5 depart from from the foundation bolt semi-finished product of bending forming, now it is described charging two pairs of rollers 6 after
It is continuous to rotate, foundation bolt semi-finished product are released, the then backhaul of the first hydraulic jack 4, and the 3rd hydraulic jack
2902nd, the 4th hydraulic jack 3002 and the 5th hydraulic jack 3004 also backhaul after execution, so as to complete
Forming process.
Present invention uses the process operation of the bending forming of uniqueness, belong to cold forming.And use with only
The shaped device and production line of special structure design, so as to which production efficiency is high, and can be with more foundation bolts of one-shot forming, significantly
The production cost of foundation bolt is reduced, there is very high popularizing value.
It should be appreciated that the purposes of these embodiments is merely to illustrate the present invention and is not intended to the protection model of the limitation present invention
Enclose.In addition, it should also be understood that, after the technology contents of the present invention have been read, those skilled in the art can make each to the present invention
Kind change, modification and/or variation, all these equivalent form of values equally fall within the guarantor that the application appended claims are limited
Within the scope of shield.
