Technical Field
The invention belongs to the technical field of aluminum profile processing equipment, and particularly relates to an aluminum profile straightening device.
Background
In order to solve the problem, the aluminum alloy profile is required to be straightened and corrected after being extruded and cooled to normal temperature.
The straightening method of the aluminum profile is various, the most common stretching and straightening method in factories is to adjust and fix a stretching head on a stretching track, so that the distance between a movable stretching head and the fixed stretching head of the straightening machine can clamp the straightened profile, then the movable stretching head and the fixed stretching head clamp two ends of the straightened profile, and finally a main straightening cylinder pulls the movable stretching head to move leftwards through a main straightening rod, so that the straightened profile generates plastic deformation, and the straightening purpose is achieved.
Straightening drawing equipment of current aluminium alloy because the centre gripping position that removes drawing head is mostly planar structure, and is not good to the tight effect of clamp of aluminium alloy, probably appears taking off power phenomenon at straightening drawing in-process, and the centre gripping is unstable, can cause the damage to the aluminium alloy sometimes.
Disclosure of Invention
The invention aims to solve the problems and provides an aluminum profile straightening device which is tight in clamping aluminum profiles, stable in clamping effect and free of damage to the aluminum profiles.
The invention is realized by adopting the following technical scheme:
the utility model provides an aluminium alloy straightener, includes fixed tensile head and rather than the tensile head of removal and the cylinder of relative setting, it includes first clamp arm and second clamp arm to remove tensile head, first clamp arm is the U-shaped structure, it is equipped with a plurality of rubber roller to arrange between two curb plates of first clamp arm, the both ends of rubber roller rotate with two curb plates of first clamp arm respectively and are connected, the cylinder is used for driving first clamp arm and second clamp arm and is close to each other or keep away from.
Preferably, the clamping surface of the second clamping arm is an arc surface with a middle part protruding upwards.
Preferably, a rubber pad is fixedly arranged on the clamping surface of the second clamping arm, the rubber pad is of an arc-shaped plate structure, and the radian of the rubber pad is the same as that of the clamping surface of the second clamping arm.
In the preferred scheme, anti-skid grains are arranged on one side of the rubber pad, which is in contact with the aluminum profile.
Preferably, the movable stretching head further comprises a connecting piece, the connecting piece comprises a body and a connecting rod A, a connecting rod B and a connecting rod C, one end of the connecting rod A is fixedly arranged on the body and extends outwards, the connecting rod A is fixedly connected with a piston rod of the air cylinder, the connecting rod B is connected with the first clamping arm, and the connecting rod C is connected with the second clamping arm.
According to the preferable scheme, two ends of the connecting rod B are hinged to the first clamping arm and the body respectively, and two ends of the connecting rod C are hinged to the second clamping arm and the body respectively.
According to the preferable scheme, the connecting rod B and the connecting rod C are welded on the body, the first clamping arm is connected with the connecting rod B through the first driving rod, two ends of the first driving rod are hinged to the first clamping arm and the connecting rod B respectively, the second clamping arm is connected with the connecting rod C through the second driving rod, and two ends of the second driving rod are hinged to the second clamping arm and the connecting rod C respectively.
The invention has the beneficial effects that:
1. the rubber roller is rotatably connected with the first clamping arm, and when the aluminum profile is stretched, the rubber roller has certain elasticity and the surface of the rubber roller is arc-shaped, so that the rubber roller can be in close contact with the aluminum profile, the acting force on the aluminum profile is ensured to be unchanged, and the damage to the aluminum profile during the stretching, straightening and stretching can be effectively avoided.
2. The three-connecting piece, the first driving rod and the second driving rod are arranged, so that the acting distance and the acting effect of the cylinder on the movable stretching head are improved, and the clamping, straightening and stretching effects on the aluminum profile are good.
