Description

Technical Field

[0001] This utility model relates to the field of straightening technology, and in particular to a straightening device for titanium and titanium alloy profiles. Background Technology

[0002] Currently, titanium and titanium alloy profiles are commonly straightened using hydraulic straightening machines. These machines have a support platform beneath the hydraulic cylinders to hold the profiles, and the hydraulic cylinders press down on and correct any bending or protrusions in the profiles. However, due to the considerable length of these profiles, manual feeding is required, especially when straightening narrow sections. This can cause the profiles to tip over due to pressure, potentially injuring operators and posing a safety hazard. Furthermore, the process is physically demanding and inefficient.

[0014] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in detail below with reference to specific embodiments.

[0015] A straightening device for titanium and titanium alloy profiles includes a hydraulic straightening machine. The hydraulic straightening machine includes a hydraulic cylinder 1 with its piston end facing downwards. A straightening platform 2 is provided below the piston end. A support 3 is provided on one side of the straightening platform 2. A linear guide mechanism 5 is provided at the upper end of the support 3 along the feed direction. A hydraulic clamp 4 for clamping the profile is connected to the linear guide mechanism 5, and the clamping jaws of the hydraulic clamp 4 are arranged along the feed direction.

[0016] In one embodiment, the linear guide mechanism 5 includes a drive mechanism 5-1 disposed on the upper end of the support 3 and two linear guide rails 5-2; the hydraulic clamp 4 is slidably connected to the two linear guide rails 5-2, and the drive mechanism 5-1 is connected to the hydraulic clamp 4, thereby driving the hydraulic clamp 4 to reciprocate along the two linear guide rails 5-2.

[0017] In one embodiment, the drive structure 5-1 is a lead screw mechanism, which is connected to the hydraulic clamp 4 via a lead screw nut and is driven by a motor.

[0018] In one embodiment, the hydraulic clamp 4 includes a first movable jaw 4-1, a second movable jaw 4-2, a third hydraulic cylinder 4-3, and a fourth hydraulic cylinder 4-4. The piston end of the third hydraulic cylinder 4-3 is connected to the first movable jaw 4-1, and the piston end of the fourth hydraulic cylinder 4-4 is connected to the second movable jaw 4-2. The profile is clamped by the first movable jaw 4-1 and the second movable jaw 4-2. The second movable jaw 4-2 has a very short stroke. Both ends of the piston rod of the third hydraulic cylinder 4-3 extend outside the cylinder sleeve, and the inner end has an external thread section 4-3-1, while the outer end is equipped with a handwheel 4-3-2. The first movable jaw 4-1 is threadedly connected to the external thread section 4-3-1. Rotating the handwheel 4-3-2 moves the first movable jaw 4-1 to a suitable workpiece clamping position and then stops. After the workpiece is loaded into the jaws, the first movable jaw 4-1 and the second movable jaw 4-2 clamp the profile, thus shortening the stroke of the first movable jaw 4-1. It improves clamping efficiency.

[0019] In one embodiment, a control cabinet 6 is also provided, and the drive structure 5-1, hydraulic cylinder 1, hydraulic cylinder 2, hydraulic cylinder 3 4-3, and hydraulic cylinder 4-4 are all controlled by the control cabinet.

[0020] When straightening titanium and titanium alloy profiles, first move the hydraulic clamp 4 to the end away from the straightening platform 2. Then, by turning the handwheel 4-3-2, move the movable jaw 4-1 to the appropriate clamping width for the profile, and release the hydraulic cylinders 4-3 and 4-4. Next, place the profile to be straightened on the straightening platform 2, with one end directly below the piston end of the hydraulic cylinder 1, and the other end between the movable jaw 4-1 and the movable jaw 4-2. Then, activate the hydraulic cylinders 4-3 and 4-4 to move the movable jaw 4-1 and the movable jaw 4-2... Clamp the profile, then activate hydraulic cylinder 2 (hydraulic clamp 4) to push the profile 7 along the feed direction until the part to be straightened is directly below the piston end of hydraulic cylinder 1. Then lock hydraulic cylinder 2. After hydraulic cylinder 1 is activated to straighten the part of the profile to be straightened, activate hydraulic cylinder 2 again to push the profile to the next part to be straightened. When the piston end of hydraulic cylinder 1 is directly below the next part to be straightened, lock hydraulic cylinder 2. Continue until the entire profile is straightened. Activate hydraulic cylinder 3 (4-3) and hydraulic cylinder 4 (4-4) to loosen the profile by moving jaw 1 (4-1) and moving jaw 2 (4-2). Remove the profile. The straightening of one profile is now complete.

[0021] It should be noted that this utility model is also applicable to the straightening of profiles made of other materials with the same structure as titanium profiles.
