Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Example 1:
[0022] Depend on Figure 1-3 As shown, a hydraulic rebar adjustment tool includes a manual hydraulic pump 1 and a U-shaped seat 2 located at the piston end of the manual hydraulic pump 1. A die head assembly 3 is provided on the side of the U-shaped seat 2 near the manual hydraulic pump 1, and a support pad assembly 4 is provided on the side away from the manual hydraulic pump 1. The piston end of the manual hydraulic pump 1 passes through the U-shaped seat 2 and abuts against the die head assembly 3. The die head assembly 3 is slidably connected to the inner side of the U-shaped seat 2.
[0023] The manual hydraulic pump 1 is equipped with a pressure lever handle 11 and a pressure relief valve 12. When in use, tighten the pressure relief valve 12, press the hydraulic handle 11 to move the piston of the manual hydraulic pump 1 forward, and unscrew the hydraulic valve 12 to reduce the pressure and cause the piston to retract.
[0024] The support pad assembly 4 is located at the open end of the U-shaped seat 2, including a support positioning block 41 located between the upper and lower inner walls of the U-shaped seat 2, and a positioning bolt 42 passing through the support positioning block 41 and the U-shaped seat 2. The thickness of the support positioning block 41 is the same as the distance between the two inner walls of the U-shaped seat 2. The support positioning block 41 is fixed to the U-shaped seat 2 by the positioning bolt 42. The support positioning block 41 provides support for the mold head assembly 3, which facilitates the straightening of the reinforcing bars.
[0025] The die head assembly 3 includes a fixed die head 31 and a movable die head 32. The fixed die head 31 abuts against the support pad assembly 4, and the movable die head 32 is slidably connected to the U-shaped seat 2. The movable die head 32 moves forward with the piston end of the manual hydraulic pump 1 and approaches the fixed die head 31. Different specifications of die head assemblies can be replaced according to different sizes of steel bars. When replacing, the support pad assembly 4 is removed, the movable die head 32 and the fixed die head 31 are slid into the U-shaped seat 2 through the slide rails in the U-shaped seat 2, and then the support pad 41 is installed.
[0026] Before use, install the die head assembly 3 corresponding to the thickness of the steel bar in the U-shaped seat 2; close the pressure relief valve 12 of the manual hydraulic pump 1, place the steel bar between the fixed die head 31 and the moving die head 32, press the hydraulic handle 11 continuously to make the piston end of the manual hydraulic pump 1 push the moving die head 32 closer to the fixed die head 31 until the bent steel bar is straightened, open the pressure relief valve 12, and take out the steel bar.
[0027] Example 2:
[0028] The similarities between this embodiment and Embodiment 1 will not be repeated here. The differences are as follows:
[0029] Depend on Figure 4 As shown, a connecting rod 5 is also provided between the piston end of the manual hydraulic pump 1 and the moving mold head 32. The connecting rod is "]" shaped, with the middle of the connecting rod connected to the piston end of the manual hydraulic pump 1 and both ends connected to the moving mold head 32 by bolts.
[0030] Example 3:
[0031] The similarities between this embodiment and Embodiment 1 will not be repeated here. The differences are as follows:
[0032] like Figure 5 As shown, the fixed mold head 31 is provided with a buckle, and the fixed mold head 31 is fixed to the U-shaped seat 2 by the buckle. The two ends of the support positioning block 41 are also provided with steel bar positioning rods 6. The steel bar positioning rods 6 are V-shaped, with the opening facing the manual hydraulic pump 1, which is used to restrict the steel bar from moving freely.
