The principle of the hot shearing machine is as follows, as shown in the attached drawings 1-12:

in the aspect of the upper rod pressing device 6, the rotating arm pushing cylinder 18 is fixedly arranged on the outer side of the side plate 8, so that the knife edge position of an aluminum rod with high temperature and a cut aluminum rod can be kept away.

The driving force is transmitted to the pressing rod driving shaft 10 through the pressing rod cylinder rotating arm 17 by the pushing cylinder, the pressing rod driving shaft 10 generates radial torsion under the action of the pressing rod cylinder rotating arm 17, and after the torsion is transmitted to the pressing rod rotating arm 11 arranged at the tail end of the pressing rod driving shaft 10, the pressing rod rotating arm 11 converts the torsion into vertical thrust through the pressing rod hinge 13 hinged with the pressing rod rotating arm 11.

Specifically, the rod pressing hinge 13 and the rod pressing rotating arm 11 both have a rotating fulcrum formed by hinging, and the torsion generated by the rod pressing driving shaft 10 drives the rod pressing rotating arm 11 to swing up and down, namely, the rod pressing rotating arm is changed from an inclined state to a vertical state, so that the process is completed that the torsion output by the rod pressing driving shaft 10 is converted into a vertical thrust to push the rod pressing seat 14 to slide up and down on the fixed sliding plate 16, and the notch 15 arranged at the lower end of the rod pressing seat 14 can clamp an aluminum rod to be hot-sheared, so that the rod pressing work of the aluminum rod is finally realized through the actions, and the hot shearing machine can shear the aluminum rod.

The length of the vertical state of the pressing rod rotating arm 11 and the pressing rod hinge 13 is the distance of the vertical stroke, and the size of the swinging angle of the pressing rod rotating arm and the pressing rod hinge is the distance length of stroke adjustment.

Lower holding rod device aspect:

the pushing cylinder is fixed at a position far away from a high-temperature part (a shear edge) of the hot shearing machine, the pushing cylinder pushes the rod supporting hinge 26 and the rod supporting arm 25 to move along the horizontal direction through the rod supporting cylinder joint, the rod supporting hinge 26 and the rod supporting arm 25 are provided with a rotating fulcrum formed by hinging, after the two are simultaneously stressed, the tilting state is changed into the vertical state, the force for pushing the horizontal direction of the cylinder is converted into the force for the vertical direction through the process, the length of the vertical state is the distance of the vertical stroke, and the size of the swinging angle of the two is the distance length of stroke adjustment.

The power of vertical direction acts on the excellent slider 27 of support of perpendicular setting at last after the conversion, through the excellent body that holds in the palm excellent slider 27 contact aluminium bar, realize holding in the palm the effect of stick, because the stroke of holding in the palm excellent slider 27 perpendicular walking corresponds with the stroke of cutting under the aluminium bar promptly, be used for realizing treating the aluminium bar that cuts off at the in-process of shearing, remain the horizontality all the time, avoid the below of aluminium bar because lack powerful and stable support, lead to the aluminium bar to appear inclining, thereby cause the phenomenon that the unevenness appears in the edge of a knife position that the aluminium bar was cuted.

In the aspect of the sizing device:

the fixed length suspension plate 40 is mainly used for being mounted in a matching manner with a hot shearing machine, a fixed length device 41 arranged on the fixed length suspension plate 40 determines the size position of an aluminum rod to be cut through a pointer 43 corresponding to a graduated ruler 42, and the fixed length device 41 is connected with the fixed length suspension plate 40 through a sliding structure (a sliding rail structure or a screw rod structure).

By referring to the numerical values on the graduated ruler 42, the length of the aluminum bar to be cut can be adjusted by the sizing device 41 through a handwheel mode.

When the telescopic push block 44 (air cylinder) of the sizing device 41 extends forwards, the output end (piston rod of the air cylinder) of the thrust of the telescopic push block 44 pushes the sizing connecting post 47 to rotate radially along the anticlockwise direction through the sizing driving arm 46 connected with the rotating shaft, the sizing connecting post 47 drives the sizing driven arm 48 to swing anticlockwise while rotating, the sizing hinge 49 connected with the rotating shaft at one end of the sizing driven arm 48 also moves anticlockwise under the action of the anticlockwise swing of the sizing driven arm 48, the sizing hinge 49 moves anticlockwise and moves the sizing arm 50 to swing clockwise to turn under the action of the rotating support of the sizing arm rotating shaft 51, and the part of the moving action is the contraction action of the sizing device 41.

When the telescopic push block 44 (cylinder) of the sizing device 41 contracts backwards, the output end (piston rod of the cylinder) of the thrust of the telescopic push block 44 pushes the sizing connecting post 47 to rotate radially in the clockwise direction through the sizing driving arm 46 connected with the rotating shaft, the sizing connecting post 47 also drives the sizing driven arm 48 to swing clockwise while rotating, the sizing hinge 49 (the sizing hinge is a free end) connected with the rotating shaft at one end of the sizing driven arm 48 also moves clockwise under the action of the clockwise swing of the sizing driven arm 48, the sizing hinge 49 moves clockwise and pulls the sizing arm 50 to swing anticlockwise under the action of the rotation support of the sizing arm rotating shaft 51 to turn until the sizing arm 50 is leveled with water (namely can be vertically contacted with the end surface of an aluminum rod), and the part of the moving action is the extension action of the sizing device 41.

When the sizing device 41 completes the extension action, the aluminum bar of the hot shearing machine is pressed against the sizing striker 52 at one end of the sizing arm 50, the feeler lever of the sizing striker 52 is stressed and contracts backwards under the action of the spring, the contraction process can touch the induction plate 53 (induction switch), the induction plate 53 controls the telescopic push block 44 (cylinder) to extend forwards after being triggered, the sizing device 41 is switched to the contraction state, the impact influence on the sizing device 41 in the aluminum bar conveying process is obviously reduced, and the occupied space of the mechanism is greatly reduced in a completely contracting mode.

Referring to fig. 11, the fixed-length driving arm 46 (point a) of the telescopic push block 44 (cylinder) connected via the rotation shaft of the hot shearing machine drives the fixed-length driven arm 48 (point B), the fixed-length hinge 49 and the connecting rod swing of the fixed-length arm 50 in the manner of driving the fixed-length connecting post 47 to rotate radially, through the setting mode, the distance C of the structure can be greatly shortened, therefore, the length and width of the fixed-length sliding seat cover 39 can become smaller and more compact, the space occupied by the fixed-length device is obviously reduced, the effective effect of compactness and high efficiency is realized, and the strong impact with the aluminum rod can be effectively avoided through the complete contraction mode, thereby realizing the purpose of prolonging the service life of the structure.

Because the structure adopts the flexible ejector pad (cylinder) of keeping away from hot shears high temperature portion and with flexible ejector pad (cylinder) mechanical linkage driven shrink connecting rod structure, consequently can also obviously reduce because the influence of high temperature environment to the adverse factor that the cylinder brought (metal material mechanical parts have high temperature resistant characteristic, consequently the high temperature environment can hardly produce the influence to the work of structure), and also do not have the oil leak condition that probably appears like the hydro-cylinder structure, consequently fine the hydro-cylinder that has adopted among the prior art promotes the structure and appears damaging the problem of oil leak risk very easily in the abominable environment of high temperature.

The foregoing is considered as illustrative of the preferred embodiments only, and it is understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
