For overcoming above-mentioned technical problem, the technical scheme that the utility model is taked is: carve the piece force-increasing mechanism, it comprises fixed mount, motor, ball-screw, tiltedly carves piece, scroll wheel, transmission arm,
Described fixed mount one side is fixed on the lathe bed, fixed mount opposite side inside is provided with slideway, the fixed mount upper and lower surface is symmetrically arranged with chute, and slideway and chute spatial vertical are provided with on the slideway and tiltedly carve piece, axle is set in the chute, the two ends of axle are positioned at the chute of fixed mount, are set with scroll wheel on the axle, and scroll wheel is positioned at the inside of the place ahead, inclined-plane fixed mount of tiltedly carving piece, the upper and lower surface of fixed mount is symmetrically arranged with chute, and the two ends of axle all are hinged with transmission arm;
The described piece of tiltedly carving links to each other with motor by ball-screw.
The described piece inside of tiltedly carving is provided with through hole.
Described motor is connected with little synchronizing wheel, and ball-screw is connected with large synchronizing wheel, and little synchronizing wheel links to each other with large synchronizing wheel by Timing Belt.
Be fixed with an end of back-moving spring on the described fixed mount, the other end of back-moving spring is fixed on the transmission arm.
The beneficial effect that the utility model compared with prior art has is: the utility model partly is not use hydraulic system for the reinforcement of making bending machine, it uses ball-screw, do not exist fluid pressure line to leak, high temperature, high pressure causes workpiece accuracy to be difficult to guarantee in the situation of leakage, high temperature, high pressure, and often maintenance is adjusted, maintenance cost is low relatively, and precision is high.
