The working principle is as follows:

when the common steel structure is sheared, the hydraulic pump station 1 (power output source) supplies oil to the pressing oil cylinder 4, the occluding cutter 6 is pushed onto the cutter holder 7 to complete the compression and fixation of the steel structure, and then the hydraulic pump station 1 supplies oil to the shearing oil cylinder 3 to enable the shearing cutter 5 to move downwards to complete the shearing step. After shearing is finished, the travel switch reaches the limit position, the hydraulic pump station 1 hydraulically reflows the shearing oil cylinder 3 and the pressing oil cylinder 4, and the shearing knife 5 and the meshing knife 6 finish return stroke action and cycle. (as shown in FIG. 7)

When the reinforcing steel bars are cut into particles, the front and rear positions of the limiting plate 12 are adjusted according to the required reinforcing steel bar cutting length. The occluding knife 6 is pressed downwards to occlude the guide metal frame 8, after the guide metal frame 8 is compressed and fixed, the control valve 2 is closed, and the oil inlet and return of the pressing oil cylinder 4 are cut off, so that the occluding knife 6 does not go into the return stroke any more. Putting the steel bar 10 to be sheared into the guide metal frame 8, pushing the steel bar 10 to be sheared to the opening of the shearing knife 5 of the shearing machine by using the pushing rake 11, enabling the steel bar 10 to be sheared to abut against the limiting plate 12, and then shearing the steel bar by the shearing knife 5 in a reciprocating mode under the driving of the shearing oil cylinder 3 to complete the grain cutting of the steel bar. Compared with other common steel structures, the steel bar has small size, so that the shearing knife 5 does not need to be lifted to a too high position during return stroke. When the shearing knife 5 returns, the movable contact 15 can be adjusted to contact the fixed contact 13 on the left side before the movable contact 14 of the travel switch, so that the return distance or time of the shearing knife 5 is shortened, and the grain cutting efficiency is improved. Because the oil circuit of the pressing oil cylinder 4 is cut off, the output power of the hydraulic pump station 1 is supplied to the shearing oil cylinder 3, the action frequency of the shearing knife 5 is accelerated, and the grain cutting efficiency is further improved. (as shown in FIGS. 1 to 6)

The guide metal frame 8 is divided into a left reinforcing steel bar placing area and a right reinforcing steel bar placing area which are equal in width through metal parting strips, when one reinforcing steel bar placing area is cut into granules, the other reinforcing steel bar placing area is filled with reinforcing steel bars, the reinforcing steel bars are alternately arranged, an idle work stage is avoided during the granule cutting, and the granule cutting efficiency is further improved.

The elastic auxiliary platform plate 17 can be pressed down when the shearing knife 5 shears, and the elastic auxiliary platform plate 17 resets after the shearing knife 5 rises. The elastic auxiliary platform is used for supporting the steel bar 10 to be sheared, normal shearing work is not affected, and smooth proceeding of the final shearing stage of the steel bar 10 to be sheared can be effectively guaranteed. The situation that the final steel bar 10 to be sheared is too short and the steel bar 10 to be sheared slips from the shearing opening is avoided. If the steel bar is cut into particles by 15 cm, but when the steel bar to be cut is only 17 cm, if the elastic auxiliary platform plate is not arranged, the steel bar to be cut can slide off from the cutting opening, so that the final cutting cannot be normally carried out. The setting of elasticity auxiliary platform board has guaranteed the utilization ratio of waiting to cut the reinforcing bar, and furthest reduces the production of waste material.

The method for modifying the shearing machine can be used for shearing equipment with similar structural principles, such as crocodile shears, tiger head shears, gantry shears and the like, and has wide application range and strong operability. When a common steel structure needs to be sheared, the guide metal frame 8 can be taken down from the shearing platform 9, the limiting plate 12 behind the shearing knife 5 is detached, the control valve 2 for controlling the oil inlet and the oil return of the pressing oil cylinder 4 is opened, and the reinforcing steel bar granulator is converted into a common shearing machine.
