Specific embodiment:
Below embodiments of the invention are described in further detail.
The present invention discloses a kind of shear of many prestress wires, and described shear comprises: frame 2, moving knife 12 and stationary knife 10.
At above-mentioned frame 2 top, fixed support has hydraulic cylinder 1, the piston rod of hydraulic cylinder 1 is hinged on moving knife fixed head 4 top by the first bolt 3, install moving knife 12 in moving knife fixed head 4 bottom by the 4th bolt 13, moving knife fixed head 4 both sides are slided in the slideway of frame 2.
Described stationary knife 10 is fixed in frame 2, stationary knife 10 and horizontal tilt, and stationary knife 10 is provided with multiple through holes 15 that many steel strand wires 14 run through.
Described moving knife 12 slides along the shear surface of stationary knife 10 and shears many steel strand wires 14 under hydraulic cylinder 1 drives.
Described frame 2 comprises: upper cross plate 2a, riser 2b, lower cross plate 2c.
Be fixed with upper cross plate 2a and lower cross plate 2c respectively at the top of riser 2b and bottom, riser 2b top is provided with piston rod groove 16, and piston rod groove 16 moves up and down for the piston rod of hydraulic cylinder 1.
Stationary knife 10 is fixed with in riser 2b trailing flank bottom, the riser 2b trailing flank of stationary knife 10 both sides is fixed by the second bolt 8 the spacing fixed head 5 of a pair specular respectively, the cross section of spacing fixed head 5 is square, and spacing fixed head 5 forms " U " font groove with riser 2b.
The slideway slided up and down moving knife fixed head 4 both sides is formed after multiple 3rd jackscrew 9, multiple first jackscrew 6 and multiple second jackscrew 7 are each passed through three sides of " U " font groove.
