Referring to fig. 3-5, in a second embodiment of the face changing structure, the face changing structure includes a turning gear 12, a rotating block 13, a positioning slot 14, a movable push block 15, a fixed frame 16, a reset push spring 17 and a face changing gear row 18, wherein the fixed frame 16 is fixedly installed on a side wall of the frame 1, the movable push block 15 is movably installed on an inner wall of the fixed frame 16, the reset push spring 17 is fixedly installed at a bottom end of the movable push block 15, the rotating block 13 is movably installed on a surface of the movable push block 15, a positioning slot 14 is formed on a surface of the rotating block 13, the positioning slot 14 is propped against one side of the straightening base 4 by an elastic force of the reset push spring 17, the turning gear 12 coaxial with the rotating block 13 is fixedly installed on an outer side of the rotating block 13, the turning gear 12 is a local gear, the face changing gear row 18 adapted to the turning gear 12 is fixedly installed on a side wall of the second straightening block 9, the face-changing gear row 18 passes through the fixing frame 16, so that in the actual working process, angle steel on the straightening base 4 passes through the locating groove 14 and continuously moves downwards after the first straightening block 3 is straightened, the movable pushing block 15 is continuously moved downwards due to the fact that the light spring is subjected to the weight of the angle steel, so that the angle steel of the locating groove 14 moves downwards to the upper part of the second straightening block 9, in the upward jacking process of the second straightening block 9, the face-changing gear row 18 is firstly contacted with the face-turning gear 12, so that the face-changing gear row 18 pushes the face-turning gear 12 to rotate, the angle steel is driven by the locating groove 14 to rotate, and when the missing parts of the face-changing gear row 18 and the face-turning gear 12 coincide, the face-turning gear 12 is not rotated, at the moment, the face-turning gear 12 is rotated by one hundred eighty degrees, and the angle steel in the locating groove 14 is completely commutated, the implementation of the mode does not need to be manually nursed, so that the labor intensity of workers is reduced.

Referring to fig. 4 and 5, in order to make the turnover gear 12 rotate with the surface-changing gear 18, the surface-changing gear 18 rotates by one hundred eighty degrees without contacting with the turnover gear 12, so that the turnover gear 12 cannot rotate due to the limitation of the shape of the turnover gear 12, the end face shape of the turnover gear 12 is semicircular, the missing parts of the surface-changing gear 18 and the turnover gear 12 are overlapped, and the turnover gear 12 cannot rotate, so that in the practical application process, the cut part of the turnover gear 12 corresponds to the surface-changing gear 18, and when the surface-changing gear 18 contacts with the turnover gear 12 for transmission, the turnover gear 12 rotates, and when the turnover gear 12 rotates to be separated from the surface-changing gear 18, the turnover gear 12 cannot rotate due to the limitation of the shape of the turnover gear 12, and the turnover gear 18 cannot move up and down due to the limitation of the separation of the surface-changing gear 18 and the turnover gear 12.

Referring to fig. 5 and 6, in order to keep the angle steel penetrating into the positioning groove 14, the positioning groove 14 may drive the angle steel to move, and meanwhile, provide a necessary condition for the following face-changing gear row 18 to push the turning gear 12 to rotate, so that a semicircular arc groove is provided on one side of the positioning groove 14, the height difference between two ends of the arc groove is three centimeters, the shape of the positioning groove 14 is set to be V-shaped, the included angle of the positioning groove 14 is ninety degrees, and two ends of the arc groove on the positioning groove 14 correspond to two ends of the V-shape respectively, so that when the angle steel is inserted into the positioning groove 14, one end of the angle steel is contacted with the semicircular arc groove on the positioning groove 14 first, thereby being pushed by the angle steel, causing the positioning groove 14 to rotate, and ensuring that the angle steel is correspondingly inserted into the V-shaped groove of the positioning groove 14.

The working principle of the invention is as follows: in use, the invention can be implemented by feeding the material into the frame 1 through an external feeding device, such as a mechanical arm or a conveyor belt, as shown in fig. 2, and feeding the angle steel onto the straightening base 4 of the first layer.

When the length of the first straightening block 3 is larger than that of the angle steel to be straightened, as the angle steel is positioned through the two straightening bases 4, the first straightening block 3 is pressed downwards along with the extrusion of the first hydraulic machine 2 to the first straightening block 3, the first straightening block 3 presses the angle steel between the straightening bases 4, the angle steel is straightened under the synchronous action of the two straightening bases 4 and the first straightening block 3 along with the continuous pressurization of the first hydraulic machine 2, after the straightening is finished, the first straightening block 3 is further pressurized, the first straightening block 3 is forced to overcome the magnetic repulsion force between the fixed magnetic block 7 and the movable magnetic block 8, the two straightening bases 4 start to be far away, the angle steel is separated from the straightening bases 4 after the first straightening block 3 is continuously pressed downwards and is positioned between the first layer and the second layer of straightening bases 4, after the angle steel is separated from the straightening bases 4, the first straightening block 3 is moved upwards, the repulsive force is applied between the fixed magnetic block 7 and the movable magnetic block 8, the bases 4 is pushed on the side wall of the bottom of the first straightening block 3, and then the angle steel is continuously output to the second layer of the first layer of angle steel 4 after the angle steel is separated from the first layer of straightening bases 4; in the same way, the straightening efficiency of the shorter angle steel is improved, the angle steel is also placed on the second straightening block 9, the angle steel is punched upwards through the second straightening block 9, the angle steel after being straightened is placed between the third layer and the second layer according to the above, and finally, the straightened angle steel is output.

When the longer angle steel is encountered for straightening, the angle steel after straightening falls to the second layer, then the angle steel of the second layer is conveyed outwards, the non-straightened angle steel part is arranged on the straightening base 4 of the second layer, the first straightening block 3 is pressed down again, the straightening base 4 of the first layer is made to be pressed into the inner cavity of the frame 1, the first straightening block 3 penetrating through the first layer is used for further pressurizing and straightening the straightening base 4 of the second layer, and according to the above, the straightening of the longer angle steel is realized.

After the longer angle steel is straightened, the angle steel is continuously pressed downwards until the angle steel falls from the straightening base 4 at the last side and is limited by the surface changing structure, so that the angle steel is overturned on the second straightening block 9, and then is pushed upwards by the second straightening block 9, and the length of the angle steel for continuous straightening is further increased.
