The specific working process of the invention is as follows:
(1) placement of the Metal Block 10
First, place metal block 10 on placing platform 7 through centre gripping equipment, under the dead weight of metal block 10, metal block 10 extrudees clearance piece 12, clearance piece 12 slides on connecting rod 11 to make clearance piece 12 tentatively fix metal block 10, first reset spring 13 is in compression state this moment (it needs to be noted that the melting point of first reset spring 13 is higher than the melting point of metal block 10, thereby can guarantee the deformation power of first reset spring 13, first reset spring 13 and second reset spring 20, and torsion spring 14's material is all the same).
(2) Fastening of the metal block 10
After metal block 10 is placed, hydraulic stem 16 is started, hydraulic stem 16 drives hammering block 17 downstream, because fixed block 19 protrudes from the lower surface of hammering block 17, so fixed block 19 contacts metal block 10 first, under the extrusion of metal block 10, can make fixed block 19 slide inside accommodating groove 18, thereby make second reset spring 20 take place compression deformation, and then make fixed block 19 fix metal block 10, simultaneously when the lower surface of hammering block 17 is laminated with the upper surface of metal block 10, because the length of fixed block 19 and the shortening deformation sum of second reset spring 20 are less than the depth of accommodating groove 18, so the lower surface of fixed block 19 can be parallel and level with the lower surface of hammering block 17, and then can not influence the hammering effect of hammering block 17.
(3) Cleaning and collecting scraps
When the hydraulic rod 16 moves downwards, the first pulling rope 9 is pulled by the hydraulic rod 16, so that the supporting rod 6 rotates under the steering action of the driving wheel 23 (it should be noted that the supporting rod 6 belongs to a torsion bar, and the same action as the matching action of the driving block 8 and the torsion spring 14, so that repeated description is not repeated in the application), under the transmission action of the driving belt 5, 2 groups of the suction fans 4 blow air into the recovery groove 21, so that the upper surface of the suction fan 4 forms negative pressure, and further, the scraps cleaned by the cleaning block 12 cannot scatter around, while the first pulling rope 9 is pulled, the second pulling rope 22 is pulled at the same time, so that the driving block 8 rotates on the placing table 7, at the moment, the torsion spring 14 is compressed and deformed, and further, the connecting rod 11 drives the cleaning block 12 to rotate, so that the scraps on the placing table 7 are cleaned in the recovery frame 2, and the worker only needs to pull out the recovery frame 2 to clean at regular intervals (the sliding between the recovery frame 2 and the workbench 1) The structure is similar to a drawer structure, which belongs to the existing mechanism and therefore is not detailed in the present application);
after the metal block 10 is hammered by the hammering block 17, the transverse length of the metal block 10 is lengthened, and the metal block 10 extrudes the cleaning block 12 at the moment, so that the cleaning block 12 further extrudes the first return spring 13, and the cleaning block 12 can not influence the cleaning effect of the cleaning block 12 and the forming of the metal block 10 when cleaning the scraps.
