Embodiment 1
[0028] Example 1: Combining Figure 2 to Figure 6 The steel bar straightening machine of present embodiment is illustrated, as figure 2 As shown, the steel bar quick straightening machine includes a sleeve 11 for straightening reserved steel bars 30, and a hydraulic device 20 communicated with the sleeve 11; the inner wall of the sleeve 11 is provided with at least two sets of hydraulic jack assemblies, namely Hydraulic jack assembly one 12 and hydraulic jack assembly two 13; wherein, each set of hydraulic jack assemblies is provided with three separate hydraulic jacks distributed radially along the axis ax of the sleeve 11 and located on the same section, and each separate hydraulic jack The jacks are all in communication with the hydraulic device 20 , and the separate hydraulic jacks can push in the direction of the axis ax of the sleeve 11 under the action of the hydraulic device 20 , thereby tightening and straightening the reserved steel bar 30 passing through the sleeve...
Embodiment 2
[0036] Embodiment 2: Combination Figure 2 to Figure 6 Illustrate the method for straightening reserved steel bars by using the steel bar quick straightening machine described in embodiment one, and the specific steps are as follows:
[0037] 1. Make the piston rod b of the separate hydraulic jack be at the initial position (that is, the state where the piston rod b is contracted), and the free end of the reserved steel bar 30 penetrates the sleeve 11 along the axis ax and is interposed between the separate hydraulic jacks;
[0038] 2. Turn on the switch located on the handle 14 to start the hydraulic main engine 21, and the top plate c of the separate hydraulic jack pushes toward the reserved steel bar 30 at the same time, so that the reserved steel bar 30 is gradually squeezed and tightened by the top plate c, thereby straightening the The reserved steel bar 30 of this section in the cylinder 11, the reserved steel bar 30 of about 25cm length can be straightened in one opera...
