Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. The round bar straightening machine is shown in figures 1-2 and comprises a rack 1, wherein a sliding groove 2 is formed in the middle of the rack 1, a fixed part and a movable part are respectively arranged on two sides of the sliding groove 2, the fixed part comprises a fixed frame 3 which is rotatably connected to the rack 1, an electric rotating mechanism is connected to the outside of the fixed frame 3, a first compression roller 4 is rotatably connected to the fixed frame 3, the movable part comprises a movable frame 5 which is rotatably connected to the rack 1, one end of the movable frame 5 extends into the sliding groove 2 and is provided with a second compression roller 6, and the other end of the movable frame 5 extends to the outside of the rack 1 and is connected with a rotating part; the first pressing roller 4 and the second pressing roller 6 are obliquely arranged on the frame 1, the oblique directions of the first pressing roller 4 and the second pressing roller 6 are opposite, arc-shaped straightening surfaces are arranged on the surfaces of the first pressing roller 4 and the second pressing roller 6, and a straightening channel is formed between the straightening surfaces on the two sides; the first press roller 4 and the second press roller 6 are positioned and then staggered back and forth along the direction of the round bar, and the adjacent press rollers are separated from each other.
The cross-sectional view of the straightening channel is shown in fig. 3, two arcs in fig. 3 are the forming effect of the straightening surface in the horizontal direction, and a circular line in fig. 3 is the outer diameter of a round rod.
The inner side of the movable frame 5 is connected with a second press roller 6 through a telescopic rod 7.
The portion of rotating is including the dwang 8 of connecting the adjustable shelf 5, and the outside key-type of dwang 8 has the rotation cover 9, and the rotation cover 9 can freely slide on dwang 8, is equipped with operating handle 10 on the rotation cover 9, and the outside of rotating the cover 9 is equipped with threaded connection dwang 8's fixation nut 11, and the inboard and the frame 1 of rotating the cover 9 are laminated each other.
The quantity of first compression roller 4 and second compression roller 6 is a plurality of, and first compression roller 4 and second compression roller 6 set up side by side respectively in the frame 1 of spout 2 both sides.
The utility model discloses a theory of operation: when the utility model is used, the operator firstly adjusts the inclination angles of the first compression roller 4 and the second compression roller 6 according to the diameter size of the round bar, so that the arc-shaped cross section of the two side straightening surfaces after the compression roller is inclined is closer to the outer diameter curve of the round bar (the arc-shaped cross section is the cross section formed by the projection of the two side straightening surfaces in the horizontal direction, and the curvature of the arc-shaped cross section is adjusted according to the inclination amplitude of the compression roller, namely, the more the compression roller is close to the horizontal state, the more the arc-shaped cross section is bent); then after the angle of the second press roller 6 is fixed, the distance between the two straightening surfaces is adjusted through the telescopic rod 7, so that the central distance between the two straightening surfaces is the diameter size of the round rod. When the inclination angle of the second press roller 6 is adjusted, an operator firstly controls the rotating sleeve 9 to rotate through the operating handle 10, so that the movable frame 5 is driven to rotate, and the angle adjustment of the second press roller 6 is realized; after the second compression roller 6 rotates in place, the operator can make one side of the rotating sleeve 9 and the rack 1 mutually fit by screwing the fixing nut 11, and then the friction limit of the rack 1 is utilized to keep the movable frame 5 in a fixed state, so that the positioning stability of the second compression roller 6 is ensured.
After first compression roller 4 and the 6 location of second compression roller, pass the alignment passageway with the one end of pole and pull it by pulling equipment, make the pole can follow and pass between the alignment face of each compression roller, utilize the alignment face to carry out the alignment to it along the spacing pore pair that the threading direction formed to the realization is to the alignment effect of pole. When the round bars with different sizes need to be straightened, the operating personnel only need to adjust the inclination angles and the intervals of the first pressing roller 4 and the second pressing roller 6, so that arc-shaped cross sections with different shapes can be formed, and the straightening of the round bars with the corresponding shapes is realized.
