In order to make the purpose, technical solutions and advantages of the present utility model more clear, the present utility model will be further described in detail below with reference to the accompanying drawings. Only this statement, the orientation words of the present utility model in the text, such as up, down, left, right, front, rear, inside, outside, etc., are only based on the accompanying drawings of the present utility model, and they are not intended to affect the present utility model. The new type of specific restrictions.

As shown in FIGS. 1-4 , the embodiment of the present invention provides a traction type aluminum material straightening device, including a horizontal slide rail 1 , a trolley 2 sliding along the horizontal slide rail 1 , and a clamping mechanism provided on the trolley 2 3. Traction mechanism 4 and reset mechanism 5,

The trolley 2 is provided with pulleys, which can slide on the horizontal slide rail 1;

The clamping mechanism 3 is used to clamp one end of the aluminum material;

The traction mechanism 4 is used to exert a constant pulling force on the trolley 2;

The reset mechanism 5 is used to reset the trolley 2 after the trolley 2 pulls the aluminum material.

The clamping mechanism 3 includes a turntable 31 , a clamping base 32 and a clamping claw 33 ; the clamping base 32 is connected to the trolley 2 through the turntable 31 , and the clamping base 32 and the clamping claw 33 can be mutually stretched Open or closed to hold aluminum. The turntable 31 allows the relative rotation between the clamping base 32 and the trolley 2 to prevent the vibration generated during the movement of the trolley 2 from being directly transmitted to the aluminum material, thereby achieving a buffering effect.

Preferably, both the clamping base 32 and the clamping claw 33 are provided with anti-slip stripes 34 . The clamping claw 33 is hinged on the clamping base 32 and is provided with a spring (not shown in the figure), and the clamping claw 33 will be in close contact with the surface of the clamping base 32 under the condition of no external force.

Preferably, a pulley shaft 21 is connected to the trolley 2 , and an upper pulley 22 and a lower pulley 23 are arranged on the pulley shaft 21 , and the upper pulley 22 and the lower pulley 23 are respectively arranged on the upper and lower sides of the horizontal slide rail 1 . underside. The upper pulley 22 and the lower pulley 23 are both provided with grooves, which are convenient to be firmly clamped on the horizontal slide rail 1 and prevent the trolley 2 from being separated from the horizontal slide rail 1 .
