Abstract

The utility model relates to a kind of reinforced bar cutting machine, comprise frame, fixed blade, upper directive slide track, lower directive slide track, movable blades, movable tool rest, clutch, bent axle, drive unit and dynamical system, clutch comprises pedal, pedal connects support bar by lever, support bar connects clutch push rod by brake spring, clutch push rod connects cut-out push rod, the end cutting off push rod is provided with semicircle projection, semicircle projection is tangent with the excentric sleeve be arranged on crankshaft eccentric shaft or be separated, cut off push rod to be connected with movable tool rest by tool rest back-moving spring.The utility model is by being installed on the Novel clutch mechanism outside reduction box, under the continuous turning effort of bent axle, make excentric sleeve pass through to cut off push rod to promote to cut off reinforcing bar with the movable tool rest motion of movable blades, reduce manufacturing cost and fault rate, add reliability, keep in repair more convenient, simultaneously due to the continuous rotation of bent axle, also eliminate the impact noise that former clutch produces.

Description

A kind of reinforced bar cutting machine

Technical field

The utility model belongs to bar cropper technical field, particularly a kind of reinforced bar cutting machine.

Background technology

Bar cropper is a kind of instrument that a kind of shear reinforcement uses, and is mainly used in the customized cut-off to reinforcing bar in the engineerings such as building construction, bridge, tunnel, power station, large-scale water conservancy.Because of its have lightweight, power consumption less, reliable operation, efficiency high, be therefore progressively machined in recent years and extensively adopt with bar mill etc., played important effect in the every field of the development of the national economy.

The operation principle of bar cropper is, by clutch drive link, connecting rod band movable slider and cutting blade reciprocating in the slideway of support, and with the ledger-plate be fixed on support with the use of cut-out reinforcing bar, edge of a knife both sides support is equipped with two backgauge framves, to reduce the dancing of reinforcing bar.

A kind of bar cropper of current use, its clutch adopts rotary key type clutch, comprises gear wheel, gear wheel with in apply mechanically binding integral, middle cover is sleeved on bent axle, and middle cover and bent axle respectively have deep-slotted chip breaker, and turn key is placed in two deep-slotted chip breakers.This rotary key type clutch needs to be installed in gearbox, when keeping in repair when breaking down, whole gearbox will be opened, and wasting time and energy, and having had a strong impact on operating efficiency.

Utility model content

The purpose of this utility model is the reinforced bar cutting machine providing a kind of convenient for maintaining, to solve the problem.

In order to achieve the above object, the technical solution of the utility model is achieved in that

A kind of reinforced bar cutting machine, comprise frame, fixed blade, upper directive slide track, lower directive slide track, movable blades, movable tool rest, clutch, bent axle, drive unit and dynamical system, described clutch comprises pedal, described pedal connects support bar by lever, described support bar connects clutch push rod by brake spring, described clutch push rod connects cut-out push rod, the end of described cut-out push rod is provided with semicircle projection, described semicircle projection is tangent with the excentric sleeve be arranged on crankshaft eccentric shaft or be separated, described cut-out push rod is connected with movable tool rest by tool rest back-moving spring.

Described pedal and clutch push rod lay respectively at the both sides of frame.

Compared with prior art, the advantage of the utility model embodiment is: the utility model is by being installed on the Novel clutch mechanism outside reduction box, under the continuous turning effort of the bent axle being provided with excentric sleeve, make excentric sleeve pass through to cut off push rod to promote to cut off reinforcing bar with the movable tool rest motion of movable blades, reduce manufacturing cost and fault rate, add reliability, keep in repair more convenient, simultaneously due to the continuous rotation of bent axle, also eliminate the impact noise that former clutch produces.

Accompanying drawing explanation

Fig. 1 is the utility model embodiment one sectional structure schematic diagram;

Fig. 2 is embodiment two sectional structure schematic diagram.

In Fig. 1 and Fig. 2,1, crankshaft eccentric shaft; 2, excentric sleeve; 3, bent axle; 4, tool rest back-moving spring; 5, clutch push rod; 6, brake spring; 7, push rod is cut off; 8, upper directive slide track; 9, movable tool rest; 10, lower directive slide track; 11, reinforcing bar; 12, frame; 13, pedal, 14, support bar.

Detailed description of the invention

Carry out clear, complete description below with reference to the technical scheme of accompanying drawing to each embodiment of the utility model, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope that the utility model is protected.

As shown in Figure 1, a kind of reinforced bar cutting machine, comprise frame 12, the front end of frame 12 is connected with fixed blade by hold(ing)-down clip, the frame at fixed blade rear is connected with directive slide track 8 and lower directive slide track 10, being provided with between upper directive slide track 8 and lower directive slide track 10 can along upper, the movable tool rest 9 that lower guideway bottom surface horizontally slips, the front end of movable tool rest 9 is connected with the movable blades coordinated with fixed blade, movable tool rest 9 rear end is connected with drive unit by clutch, clutch comprises pedal 13, pedal 13 connects support bar 14 by lever, support bar 14 connects clutch push rod 5 by brake spring 6, clutch push rod 5 connects cut-out push rod 7, the end cutting off push rod 7 is provided with semicircle projection, semicircle projection is tangent with the excentric sleeve 2 be arranged on crankshaft eccentric shaft 1 or be separated, cut off push rod 7 to be connected with movable tool rest 9 by tool rest back-moving spring 4.

Pedal 13 and clutch push rod 5 lay respectively at the both sides of frame 12, can increase the active force of lever like this, can save pedal force.

Operation principle of the present utility model is, clutch push rod 5 will cut off push rod 7 jack-up under the effect of brake spring 6, and cut-out push rod is separated with the excentric sleeve of continuous rotation; When needs cut off reinforcing bar 11, foot-treadle 13, pedal 13 by the effect of lever make clutch push rod 5 overcome brake spring 6 act on the effect of self gravitation under decline, clutch push rod 5 drives cut-out push rod 7 to decline, the semicircle projection of cut-out push rod 7 end is contacted with excentric sleeve 2 is tangent, excentric sleeve 2 promotes to move with the movable tool rest 9 of movable blades by cutting off push rod 7, and movable blades coordinates fixed blade to cut off reinforcing bar, circulates and so forth.

This use is novel instead of turn key, connecting rod and gear heart cover with novel clutch, clutch is installed on outside reduction box, reduce manufacturing cost and fault rate, add reliability, keep in repair more convenient, simultaneously due to the continuous rotation of bent axle, also eliminate the impact noise that former clutch produces.

The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
