Working principle:
The heated long aluminum bar in the heating furnace is conveyed to the position of the bar receiving translation mechanism forwards through the rear roller assembly, at the moment, the long aluminum bar is fixed by the fixed-length mechanism on one side of the bar receiving translation mechanism, the long aluminum bar is fixed by the front clamping plate and the rear clamping plate of the hot shearing machine after the fixed-length mechanism is positioned in place, and then the main oil cylinder drives the movable tool apron to move downwards, so that short aluminum bars with required lengths are sheared; after the short aluminum is sheared, the rod withdrawing mechanism withdraws the sheared residual long aluminum rods back into the heating furnace, the rod ejecting mechanism ejects the sheared short aluminum rods forwards out of the frame position, the rod receiving translation mechanism translates the short aluminum rods to one side, and the short aluminum rods are conveyed to the extruder through a manipulator arranged on one side of the hot shearing machine; when the extrusion of the former short aluminum bar is about to be completed at the extruder, repeating the hot shearing of the former short aluminum bar after the operation is completed, and repeating the cycle. The whole hot shearing process of the hot shearing machine is reasonable in design and smooth in operation, so that the hot shearing efficiency of the aluminum bar is greatly improved, and the hot shearing effect of the aluminum bar can be effectively ensured;
when the sizing mechanism is used for sizing and positioning a long aluminum rod, the speed reducer drives the transmission screw rod to rotate, so that the transmission nut drives the sizing frame to move to a specified position on the guide rail, the sizing stop rod assembly is outwards opened to a position vertical to the sizing frame by the first cylinder, at the moment, the hinge points of the first connecting rod and the first cylinder frame are positioned on the same straight line with the hinge points of the two ends of the second connecting rod, a dead point position is formed, and the positions of the cylinder and the connecting rod mechanism are effectively prevented from being changed when the aluminum rod impacts the sizing stop rod assembly, so that the position of the sizing stop rod assembly is effectively prevented from deflecting in the sizing process, and the sizing and positioning accuracy of the aluminum rod is greatly improved;
The guide rod rack of the fixed-length guide rod assembly is provided with the induction device, when the front end of the aluminum rod reaches the guide rod surface, the induction piece is pushed out of the through hole of the guide rod surface, so that the induction piece rotates, the left swing rod of the induction piece is contacted with the induction switch, and accordingly an aluminum rod in-place signal is sent out, and at the moment, the aluminum rod is sheared by the hot shearing machine, so that the fixed-length precision of the aluminum rod can be effectively improved;
The left side and the right side of the stop surface of the fixed-length stop mechanism are provided with the rod buckling blocks, the left and the right rod buckling blocks can clamp or loosen the end parts of the aluminum rods through the second cylinder, the rod buckling blocks do not act during normal fixed-length operation, when the long aluminum rods are sheared to a residual length slightly longer or slightly shorter than the fixed-length (the residual length does not influence the normal operation of the extruder), shearing operation is not needed (otherwise, the former aluminum rod or the latter aluminum rod is sheared to generate an aluminum rod sheet) at this moment, the head of the aluminum rod can be directly clamped by the rod buckling blocks to pull the aluminum rod out of the frame position forwards (the rod pushing mechanism cannot push the aluminum rod out when the aluminum rod is not sheared), so that the aluminum rod is smoothly removed by the rod receiving traversing mechanism, the production efficiency is improved, and the loss of the aluminum rod is reduced;
The bar clamping mechanism is mainly used for clamping short bars, and specifically, when a current long aluminum bar is sheared to a length between one time of the fixed length and 2 times of the fixed length (the shearing to the fixed length is likely to cause waste of a section of aluminum bar), the residual length of the aluminum bar can be sheared into a front section and a rear section of short bars (both the two sections are smaller than the fixed length) which are approximately equal through a hot shearing machine, firstly, a rear section of short bar is clamped through the bar clamping mechanism, at the moment, the rear long aluminum bar ejects the front section of short bar, the rear long aluminum bar is sheared into a section of short bar through the hot shearing machine, the front section of short bar can be supplemented to the fixed length, and the front section of short bar supplemented to the fixed length is moved out and fed into the extruder through the bar connecting translation mechanism; at this moment, the bar withdrawing mechanism withdraws the rear long aluminum bar into the heating furnace, the bar clamping mechanism puts down the rear short bar, the rear long aluminum bar ejects the rear short bar, the rear long aluminum bar is sheared into a section of short bar again through the hot shearing machine, the section of short bar can be used for repairing the rear short bar to the specified length, the rear short bar which is repaired to the specified length is moved out and fed into the extruder through the bar receiving translation mechanism, the loss of the aluminum bar can be greatly reduced, and the material utilization rate is effectively improved.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions that are formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of the present invention.
