Description

A steel fiber manufacturing device combined lengthen skill}

The present invention relates to a steel fiber manufacturing machine for manufacturing steel fibers for improving the concrete properties, more specifically, the drawing function configured to produce steel fibers while drawing to a thickness suitable for steel fibers using a thick steel wire It relates to a steel fiber manufacturing machine.

In general, steel fiber is used in concrete construction such as buildings, bridges, tunnels, etc. in order to improve the properties of concrete such as the failure coefficient, shear strength, torsional strength and fatigue resistance of concrete. There are steel fibers produced by cutting to width, and steel fibers manufactured by bending and cutting steel wires having a thickness suitable for the steel fibers.

Looking at the configuration of a steel fiber manufacturing machine that is produced by bending and cutting a number of steel wires of the same thickness suitable for steel fibers in the same interval as the latter in the conventional steel fiber, there is a bending and cutting device and is configured to mount the winding drum on one side There is a sphere.

Since the steel fiber manufacturing machine of the above configuration cannot make steel wire of the thickness suitable for steel fiber by itself, the steel fiber is drawn by drawing a thick steel wire with a thickness suitable for use as a steel fiber in a separate drawing machine and winding it on a drum and transporting it. Steel fibers were prepared by placing them on the holder of the machine.

This makes it difficult to wind and transport thick steel wires in a separate drawing machine to the drum in the amount suitable for making and transporting the steel wires, and the steel wires suitable for steel fibers are very thin. It was also damaged during handling.

In addition, since the steel fibers are bent several times at equal intervals, the dispersibility becomes very bad, and there is a disadvantage that they are entangled with each other when used.

In addition, by separately installing and operating the steel fiber manufacturing machine and the drawing machine, there is a problem such that the cost of manufacturing steel fiber is increased due to the high facility cost and manpower.

The present invention provides a relatively thick steel wire from the drawing device to the steel fiber by installing a drawing device consisting of a die and a drum on one side of the steel fiber manufacturing machine having a circular blade configured to bend only both ends of the steel fiber in order to solve the above problems. It is intended to provide a steel fiber manufacturing machine having both a drawing function and at the same time supplying to a steel fiber maker while drawing a thickness suitable for use to produce steel fibers bent at both ends.

When described in detail with reference to the accompanying drawings a preferred configuration for a steel fiber manufacturing machine also serves as a pull function of the present invention is as follows.

As shown in FIG. 1, the present invention has a drawing device 2 formed at one side of the steel fiber manufacturing machine 1.

The steel fiber manufacturing machine (1) is a pair of circular blades (3) (4) for bending and cutting the steel wire for the steel fiber is connected to the rotating means, and the third guide rods (5) and secondary guides formed thereafter It consists of a roller 6, a secondary guide rod 7, a primary guide roller 8, a primary guide rod 9 and a guide drum 10.

The drawing device 2 is provided with drums 11 and 12 on both sides, and the upper and lower dice fixing racks 14 and 15 provided with the dies 13 between the drums 11 and 12. It is.

The drums (11) and (12) are composed of a plurality of steps having different diameters, each having a conical shape, and the upper and lower die fixing bars (14) (15) installed between the drums have several incisions at regular intervals. It is formed by forming the die (16) and the dies (13) separately installed inside the cutout (16).

The dies 13 are configured such that the steel wire becomes thinner toward the exit from the side where the thick steel wire 41 enters.

In the drawings, reference numeral 40 denotes a guide roller, 41 thick steel wire, 42 steel wire holder, 43 steel fiber wire, 44 cooling oil sprayer, 45 steel fiber, 46 bending portion, and 47 cutting blade. .

Referring to the operation of the steel fiber manufacturing machine with a pull function configured as described in detail as follows.

First, the coarse steel wire 41 wound in a predetermined amount is placed on the steel wire holder 42 and the coarse steel wire 41 is provided between the drum 11 and the drum 12 provided on both sides of the drawing device 2. The dies 14 and 15 pass through the dies 13 and are drawn out to the guide roller 40 and the guide drum 10.

Then, when the steel fiber manufacturing machine and the drawing device are driven, the thick steel wire 41 suitable for use as a steel fiber by the dies 13 moves the thick steel wire 41 while the drums 11 and 12 of the drawing device rotate. (43) is made.

At this time, the cooling oil is sprinkled by the cooling oil spraying stand 44 to cool the drums 11 and 12, the die 13, and the die fixing stand 14 and 15.

Steel fiber wire 43 made of the above process is a guide drum 10, the primary guide rod (9), the primary guide roller (8), the secondary guide rod (7), the secondary guide roller (6), Steel fiber 45 is produced while the bending and cutting process is continuously performed between the circular blades (3) and (4) passing through the third guide rod (5).

Looking at the bending and cutting process of the circular blade for producing the steel fiber 45 in detail, while the steel fiber wire 43 is supplied between the circular blade (3) (4) a constant interval to the circular blade (3) (4) The bending and cutting are repeated by the action of the bent portion 46 and the cutting blade 47 formed as the steel fiber 45 is produced.

The present invention as described above has a drawing device formed on one side of the steel fiber manufacturing machine to draw a thick steel wire to make the thickness suitable for use as a steel fiber steel wire, and at the same time can produce a steel fiber immediately, it is excellent in workability and improves productivity By reducing the cost, it is possible to prevent the steel wire from being damaged during transportation, and also to reduce the equipment cost and manpower.
