Abstract
The invention discloses a hydraulic cutting-off system of a straightening machine. The hydraulic cutting-off system of the straightening machine comprises a cutter driven by a hydraulic oil cylinder, wherein the cutter is driven by the hydraulic oil cylinder to perform feeding and retracting motion and is mounted on a base; a cutter slot for allowing a steel bar to pass through is reserved in the base; the cutter is located on one side of the cutter slot; when the cutter is fed, the cutter slot stays in a closed state; when the cutter is retracted, the cutter slot stays an open state; the base is in sliding fit with a slideway; and one side of the base is pulled by an elastic piece. The hydraulic cutting-off system of the straightening machine solves the technical problem that the cutter is easily broken by the steel bar which is discharged at a high speed.
Description
Technical field
The present invention relates to metal working technical area, particularly a kind of straightener hydraulic cutting system.
Background technology
At present, bar straightener is made up of bar straightening mechanism and shut-off mechanism two parts, then reinforcing bar completes customized cut-off, in the prior art by completing whole straightening process after bar straightening mechanism by shut-off mechanism, what shut-off mechanism was taken is mechanical structure, there is operating noise greatly in this structure, fault rate shortcoming high also uses hydraulic cutting mechanism, but the cutting knife of hydraulic jack control is in the presence of entering, and withdrawing speed is slower, and the reinforcing bar of discharging easily pushes up bad cutting knife at a high speed.
The content of the invention
Invention mainly solving the technical problems that provide that a kind of noise is small, the low straightening hydraulic cutting system of fault rate.
Above-mentioned technical problem is solved, one aspect of the present invention is：A kind of straightener hydraulic cutting system is provided, including the cutting knife that hydraulic jack drives, described cutting knife does feed, retracting movements under the drive of hydraulic jack, and described cutting knife is arranged on base, the cutting knife notch for allowing reinforcing bar to pass through is left on base, described cutting knife is located at the side of cutting knife notch, and when cutting knife feed, cutting knife notch is in closed state, when cutting knife withdrawing, cutting knife notch is in open mode, and described base is slidably fitted in slideway, the flexible part of a layback of base.
In solution technique, travelled forward from the discharging opening of straightener after bar straightening, into cutting knife notch, now cutting knife notch is in closed state, and reinforcing bar heads on base and travels forward, because base is to slide, cutting knife will not be bad by reinforcing bar top, and after cutting knife withdrawing, cutting knife notch is opened, under the pulling of elastic component, base resets, cutting knife feed, reinforcing bar is cut off, after reinforcing bar is cut off, cutting knife notch is in closure state, circulates again.
The beneficial effects of the invention are as follows：The present invention solves the technical barrier that the reinforcing bar for discharging at a high speed easily pushes up bad cutting knife.
Brief description of the drawings
Fig. 1 is a kind of view of the embodiment of the present invention；
Fig. 2 is another view of the embodiment of the present invention；
The mark of each part is as follows in accompanying drawing：1st, cutting knife 2, base 3, cutting knife notch 4, slideway 5, elastic component 6, reinforcing bar.
Specific embodiment
Below in conjunction with the accompanying drawings to embodiment further instruction.
As shown in Figure 1, a kind of straightener hydraulic cutting system, including the cutting knife 1 that hydraulic jack drives, described cutting knife does feed, retracting movements under the drive of hydraulic jack, described cutting knife 1 is arranged on base 2, the cutting knife notch 3 for allowing reinforcing bar 6 to pass through is left on base 2, described cutting knife 1 is located at the side of cutting knife notch 3, when 1 feed of cutting knife, cutting knife notch 3 is in closed state, and when 1 withdrawing of cutting knife, cutting knife notch 3 is in open mode, described base 2 is slidably fitted in slideway 4, the flexible part 5 of a layback of base 2.
In solution technique, travelled forward from the discharging opening of straightener after bar straightening, into cutting knife notch 3, now cutting knife notch 3 is in closed state, and reinforcing bar heads on base 2 and travels forward, because base 2 is to slide, cutting knife 1 will not be bad by reinforcing bar top, and after 1 withdrawing of cutting knife, cutting knife notch 3 is opened, as shown in Fig. 2 under the pulling of elastic component 5, base 2 resets, the feed of cutting knife 1, reinforcing bar is cut off, after reinforcing bar is cut off, cutting knife notch is in closure state, into next cyclic process.
The present invention solves the technical barrier that the reinforcing bar for discharging at a high speed easily pushes up bad cutting knife.
