Specific embodiment

The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.

As shown in Figures 1 to 4, a kind of silicon ingot melts down tailing processing equipment, including：The work of tailing 4 is melted down for placing silicon ingot Make platform 1, be arranged at the top surface of workbench 1 and spacing limited block 2, and multiple for rushing carried out for tailing 4 is melted down to silicon ingot Break up the percussion mechanism 3 that bad silicon ingot melts down the side of tailing 4；Silicon ingot melts down side one percussion mechanism of correspondence of tailing 4 3。

The silicon ingot is melted down in tailing processing equipment, and limited block 2 is L-shaped.As one embodiment of this programme, limited block 2 Number be 2,22 corresponding clamping silicon ingots of limited block melt down 2 of tailing 4 tiltedly to edge arrange.As this programme Another embodiment, the number of limited block 2 is 4, and 4 edges that 42 corresponding clamping silicon ingots of limited block melt down tailing 4 set Put.Tailing 4 is melted down to silicon ingot by limited block 2 carries out spacing, simple structure, and can effectively prevent silicon ingot from melting down tailing 4 Life is moved horizontally.

The silicon ingot is melted down in tailing processing equipment, and percussion mechanism 3 includes alloy hammer 31 and hydraulic cylinder 32, and hydraulic cylinder 32 is fixed In the top surface of workbench 1, and for driving alloy hammer 31 to hammer the side that 31 corresponding silicon ingots melt down tailing 4 into shape along perpendicular to alloy Direction movement.It is the cubic bodily form as silicon ingot melts down tailing 4, therefore the top surface of workbench 1 arranges 4 percussion mechanisms 3, silicon ingot Melt down side one percussion mechanism 3 of correspondence of tailing 4.Wherein, 4 hydraulic cylinders 32 are connected with control system.During work, control System processed controls 4 hydraulic cylinders 32 simultaneously and works, and hydraulic cylinder 32 drives connected alloy hammer 31 along corresponding silicon ingot The vertical direction movement of the side of tailing 4 is melted down, so as to 4 sides that tailing 4 is melted down to silicon ingot carry out impact failure.Separately Outward, the pressure parameter of the stroke distances and hydraulic system of regulation hydraulic cylinder 32 can be passed through, to meet the side that tailing 4 is melted down to silicon ingot The different degrees of crackle in portion is destroyed, easy to operate.

The silicon ingot is melted down in tailing processing equipment, and the edge of the close limited block 2 of alloy hammer 31 opens up fluted 311； When the medial surface contact silicon ingot of alloy hammer 31 melts down the side of tailing 4, limited block 2 is entered in groove 311.

The silicon ingot is melted down in tailing processing equipment, and the medial surface of alloy hammer 31 is provided with multiple projections 312, to reduce alloy Hammer 31 melts down the contact area of tailing 4 with silicon ingot, and impact failure effect is more preferable.

The silicon ingot is melted down in tailing processing equipment, and alloy hammer 31 is hammered into shape for WC-Co alloys, and wearability preferably, is not likely to produce gold Category chip, so as to avoid that the generation pollution of tailing 4 is melted down to silicon ingot.

The utility model proposes a kind of silicon ingot melt down the operation principle of tailing processing equipment and be：During work, silicon ingot is returned Stove tailing 4 is positioned on the workbench 1 between limited block 2, is controlled 4 hydraulic cylinders 32 simultaneously by control system and is driven alloy hammer 31 impact failure silicon ingots melt down 4 sides of tailing 4, make the lines that silicon ingot melts down the crackle laterally of tailing 4 split, and process effect Rate is high, and cracking effect preferably, and will not be melted down tailing 4 and pollute to silicon ingot.
