Abstract

The utility model relates to an automatic steel bar straightening cutting machine, which is composed of a steel wire straightener, a steel wire puller, a steel wire cutter and a steel wire length controller. The utility model is characterized in that steel bars can be straightened when the steel bars are passed from a central shaft in a steel frame whose both sides are fixed with three concave wheels, a pull shaft is covered with a concave wheel to form the puller, and a lower shaft corresponding to the puller is aiso covered with a concave wheel with springs; the side of a cutting knife seat which is provided with an upper and a lower cutter blades and a cutter composed of a cutting rod are also provided with the length controller composed of an electromagnet touch-connecting switch and an operation rod, and the whole machine can be driven by a motor. The automatic pullout, automatic straightening, automatic control and automatic cutting of the steel bars can be realized, work efficiency can be enhanced and labour intensity can be reduced, and steels can not be wasted.

Description

The automatic straightening cutting machine of reinforcing bar

The utility model relates to a kind of aligning, cutter sweep of metal wire rod, the automatic straightening cutting machine of especially a kind of reinforcing bar.

At present, in building trade, the aligning of reinforcing bar adopts hoist engine and bar straightener to come straightening mostly, and then with manually cutting off.Utilize hoist engine or straightener all to need three workman Lai La reinforcing bars, cut off after pulling out tens meters, cut off according to the used length of reality again, one little section reinforcing bar of fixing reinforcing bar in two and remaining not enough length has been wasted, and working strength of workers is also quite big.

The purpose of this utility model provides and a kind ofly reinforcing bar can be pulled out automatically, straightening automatically, the automatic straightening cutting machine of reinforcing bar controlling length and cut off automatically, not only reduced labor intensity but also increased work efficiency automatically.

The utility model is made up of several parts of steel wire straightener, puller, cutter and controlled-length apparatus.

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is that the utility model A is to side view.

Fig. 3 is that the utility model B is to side view.

Fig. 4 is that the utility model C is to side view.

Fig. 5 is that the utility model D is to side view.

This automatic bar straightening cutting machine is horizontal rectangular shape, by the steel wire straightener (1), several parts of puller (6), cutter (11) and controlled-length apparatus form. Motor (1) Drive steel wire straightener (3) and power transmission shaft (14) by driving-belt, power transmission shaft (14) is through gear Drive to divide to axle (4) and pull out axle (5), at the other end of power transmission shaft (14) through cam, bearing (13) drive cut-out bar (12). Steel wire straightener (3) as shown in Figure 1, in the rectangle strongbox The central shaft (2) of perforation in the middle of is arranged, and in order to pass steel wire, axle two is all overlapped bearing, Each fixes an iron plate on the long limit of rectangle strongbox, interior spaced apart three two of fixing of iron plate Little recessed wheel the in the middle of big, and form 45° angle with iron plate, when straightener one rotates, just steel The muscle straightening. Puller (6) is recessed wheel of slotting in the middle of axle (5) cover one pulling out, the below Also fix recessed wheel of fluting in the middle of on corresponding parallel with pulling out axle (5) axle, they are two years old Each cover has a spring (18) on the iron of limit connection bearing, such as Fig. 2, utilizes the pressure of spring, Steady Rebar, rotate when pulling out axle, reinforcing bar (17) is pulled out between recessed wheel of two flutings. Cut off Device (11) is made up of cutting tool rest and cut-out bar (12), and the cutting tool rest is again by firm banking and dress There is the movable seat of honour of upper and lower blade (16), (15) to form. Controlled-length apparatus by electromagnet (7), Magnetic connects switch (10) and drive link (9) forms, and is installed in by the cutting tool rest, and (8) are lead.

During start, motor drives straightener and power transmission shaft, transmission simultaneously by V belt The beam warp conical gear drives and divides to axle, divides to the drive of beam warp belt and pulls out axle, and power transmission shaft simultaneously Also driven the cut-out bar, because the effect of cam, become rotatablely moving and to move up and down institute Ceaselessly move up and down to cut off bar. After reinforcing bar process straightener is by straightening, by pulling out Device is pulled out, and sends into cutter, passes in the middle of upper bottom knife always. If need length Be 1 meter long, just the power supply of electromagnet bumped and connect switch and be contained in place away from one meter on the blade. Such as 10 meters long places that just are contained in 10 meters of need. When the head of reinforcing bar is run into and connect switch, power supply Connect, electromagnet sends suction, through drive link the cutting tool rest is pulled out, and cuts off bar upper slitter Sheet is depressed, at once bar cutting. Reinforcing bar one is disconnected, bumps to connect switch disconnection electromagnet power supply. So spring retracts original position to the cutting tool rest again. Cut off bar and again can't press cutter. As This circulation.

The utility model can be realized reinforcing bar is automatically pulled out, automatic alignment, automatically controlled length With automatic cut-out. A hoist engine or a straightener need be joined three workmans, one day can only One and half 6.5 millimeters round steel straightening and cut-out, and waste the land and pick up many jin steel, This automatic bar straightening cutting machine only needs a workman, and one day just can be easily 5 tons 6.5 so round steel straightening and the cut-out of millimetre are controlled owing to this machine is equipped with length, automatically not The waste steel.

Claims

1, the automatic straightening cutting machine of a kind of reinforcing bar is made up of steel wire straightener, bearing, motor, power transmission shaft, blade, gear, spring, it is characterized in that:
