Problems solved by technology

[0002] At present, most of the straightening equipment for large-scale bars use rollers to realize the turning and transmission of bars. This method is easy to cause the bar to slip when turning over, and it is easily affected by its own swing and inertia during transmission, which makes the bending point of the bar Changes after detection, the precise positioning of the bar cannot be achieved, thus affecting the straightening accuracy of the bar

Embodiment 1

[0029] Such as figure 1 As shown, the turning mechanism and feeding trolley for the bar straightening machine are composed of traction mechanism 1, bar turning mechanism 2, and feeding trolley 3. The traction mechanism 1 is connected with the feeding trolley 3 through a steel rope, and when the feeding trolley 3 is being pulled, the steel rope is always in a taut state.

[0030] Such as figure 2 As shown, the traction mechanism 1 is composed of a winch assembly 1-1 and a steel rope guide wheel set 1-2.

[0031] Such as image 3 As shown, the bar turning mechanism 2 consists of a motor reducer 2-1, a sprocket chain 2-2, a hydraulic gripper 2-3, a hydraulic rotary joint 2-4, a turning base 2-5, and a bearing pretensioner 2- 6. Composed of rotating shaft 2-7, bearing pre-tightening nut 2-8, roller bearing 2-9, sleeve 2-10, and hydraulic pump station 2-11. The hydraulic gripper 2-3 is fixed on one end surface of the rotary shaft 2-7, and the inlet and outlet oil pipes of the ...

Abstract

The invention discloses a bar overturning and conveying device for a bar straightening machine. The bar straightening machine consists of a traction mechanism (1), the bar overturning mechanism (2) and the conveying trolley (3), an oil inlet and outlet tube of a hydraulic clamping jaw (2-3) of the bar overturning mechanism penetrates through a rotating shaft (2-7) through three grooves of the rotating shaft (2-7) to be connected with a hydraulic rotary joint (2-4), and a motor speed reducer (2-1) drives the rotating shaft (2-7), the hydraulic clamping jaw (2-3) and the hydraulic rotary joint (2-4) to rotate together via a sprocket chain (2-2); and a bar side push raising positioning device (3-2), a bar rolling raising device (3-3), a bar positioning device (3-4), a roller train (3-5) and a hydraulic pump station (3-6) of the conveying trolley are fixed on a support frame (3-1). The bar side push raising positioning device (3-2), the bar rolling raising device (3-3) and the bar positioning device (3-4) are respectively arranged independently, and the numbers of the bar side push raising positioning device (3-2), the bar rolling raising device (3-3) and the bar positioning device (3-4) are determined according to the lengths of bars required to be straightened.

Description

technical field [0001] The invention relates to the field of straightening equipment in the bar straightening industry, which can realize precise positioning of the bending point of the bar. Background technique [0002] At present, most of the straightening equipment for large-scale bars use rollers to realize the turning and transmission of bars. This method is easy to cause the bar to slip when turning over, and it is easily affected by its own swing and inertia during transmission, which makes the bending point of the bar Changes occur after the detection, and the precise positioning of the bar cannot be realized, thereby affecting the straightening accuracy of the bar. Contents of the invention [0003] The object of the present invention is to provide a bar turning mechanism and a feeding trolley for a bar straightening machine aiming at the deficiencies of the prior art. , thereby improving the straightening accuracy of the bar. [0004] The purpose of the present...
