Abstract

PURPOSE:To provide the wire drawing machine causing no measuring errors of a flaw detector due to a wire material not being waved made by composing vertically movably the winding drum fitting base provided with a winding drum, driving device and speed reducing device for the base stand providing a die. CONSTITUTION:The wire rod W in the state of fixing a tip part S to the drum lower end part 10 by a tongue 9 is continuously wound on the winding drum 3 rotated in an arrow mark M direction by a specific torque. Meanwhile due to the drum 3 descending with a winding drum fitting base 7 at specific descent speed V, the part on which no wire rod W is wound on the outer peripheral face 8 is always descended at the same height position as that of a die 2. Therefore, there is no superposing of the wire rod W nor bending by the part through which the wire rod W passes the die 2 as well, etc., a pass line P can always be held linearly. And in the case of the tongue 9 being descended, the wire rod W is descending to the carrier 17 at the lower part from the tip side by releasing the grip of the tongue 9 to decide the position where the wire rod W falls by separating from the drum 3 by a touch roller 11....

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wire drawing machine for drawing a wire rod to a predetermined small diameter.

C. Prior art and its problems] Recently, wire drawing machines having a structure in which the tip of the wire to be processed is automatically gripped with tongs have been widely used. However, conventional wire drawing machines of this type have a structure in which the wire is sequentially wound onto a winding drum while a die box containing dies for finishing the wire into a predetermined outer diameter is moved up and down. For this reason,
It was extremely difficult to arrange the device in a connected manner with pre-process equipment such as a cutting tip machine for processing the tip of the wire rod and a flaw detection device for inspecting the presence or absence of flaws in the wire rod. That is, since the pass line of the wire rod moves up and down, it is difficult to connect the wire rod continuously to the above-mentioned pre-processing equipment.

An object of the present invention is to provide a wire drawing machine that solves the above problems.

[Means for solving problems]

In the present invention, a winding drum mounting base provided with a winding drum, a drive device, and a deceleration device is configured to be movable up and down with respect to a base provided with a die.

[Effect]

The winding drum, drive device, and deceleration device move up and down as one. As a result, the tongs on the winding drum can be set to match the position (height) of the die, and the tongs on the winding drum can be sequentially wound on the winding drum.

The dice no longer need to move up and down at all. Accordingly, the pass line of the wire remains constant without vertical movement.

〔Example〕

Embodiments of the present invention will be explained in detail based on the drawings.

In FIG. 1, 1 is a wire drawing machine according to the present invention, and 2 is a die for finishing the wire W to a predetermined outer diameter.

The wire drawing machine 1 includes a winding drum 3 for continuously winding a wire rod W passed through a die 2 while applying a predetermined tensile force, a speed reduction device 4 for driving the rotation of the winding drum, and a speed reduction device 4 for driving the rotation of the winding drum. It includes a drive device 5 that applies rotational force to the winding drum 3 via a device 4, and a winding drum mount 7 on which the winding drum 3, the drive device 5, and the speed reduction device 4 are installed. This winding drum mounting base 7 is composed of an upper box part 7a and a lower elevating frame part 7b. The speed reduction device 4 is comprised of large and small speed reduction gears 33, etc., and is housed in a box portion a of the winding drum mounting base 7. Note that the driving device 5 is an electric motor. The winding drum 3 is provided to project downward from the bottom of the box portion 7a,
Tongs 9 for gripping the tip S of the wire W are provided on the outer peripheral surface 8 of the winding drum 3 and at the lower end 10 of the drum. 11... is a touch roller and the winding drum 3
It is disposed close to the outer circumferential surface 8 of the box part 7a and is attached to the box part 7a via the pivot arms 12. Reference numeral 13 denotes a touch roller drive section provided on the upper surface of the winding drum mounting base 7.

Reference numeral 14 designates a group of correction rollers consisting of a plurality of rollers 15, which are fixed on the base 16 together with the dice box 46 that holds the dice 2, and are always held in a fixed position. The rollers 15 are arranged in a staggered manner along a path line P corresponding to the center line of the wire W.

Note that below the winding drum 3 there is a coiled wire W.
A carrier 17 is provided for receiving the water.

On the opposite side of the winding drum 3 with respect to the correction roller group 14, a cutting tip applicator 18 and a flaw detection device 19 are arranged along the pass line P. The cutting tip machine 18 has a die 2
This is installed to perform a predetermined taper treatment on the tip end S of the wire before inserting the wire W into the wire.

As shown in FIGS. 2 and 4, the winding drum mounting base 7 is configured to be movable up and down with respect to the base 16 provided with the dice box 46.

Specifically, the elevating frame portion 7b of the mounting base 7 is fitted into a guide base 21 erected on the floor 20, and the guide grooves 22 formed on the outside of the frame portion 7b... The guide base 21
The interior can be raised and lowered in the directions of arrows A and B.

Reference numeral 24 denotes a lowering device, which is connected to the inner bottom surface 25 of the guide base 21.
The lower end portion 26 is fixed to via a mounting member 27.

The imaginary line in FIG. 2 indicates the position where the winding drum mounting base 7 is in the uppermost position with respect to the base 16 on which the die 2 is installed, and S! Is!
This shows the starting time (setting time) when the tongue 9 of the drum 3 is at the same height as the horizontal pass line P. In other words, the virtual line is the tongue 9 at the beginning of winding the wire W.
and the positions of the mounting base 7, etc. are shown. As shown in FIGS. 5 and 6, the guide base 21 has a guide cavity 28 into which the elevating frame portion 7b of the winding drum mounting base 7 is inserted. On the opposing wall surfaces 29, 29 and the wall surface 30 perpendicular thereto, the guide rollers 23...
are respectively attached in an inwardly protruding manner.

Next, as shown in FIGS. 7 and 8, the winding drum mounting base 7 corresponding to the wall surfaces 29, 29, 30 of the guide base 21
t on the outer wall surfaces 31, 31, 32 of the guide groove 2.
2... are formed in the vertical direction.

As shown in FIG. 3, the wire rod W, whose tip end S is fixed to the lower end lO of the drum by the tongs 9, is continuously wound around the winding drum 3 rotating in the direction of arrow M with a predetermined torque. However, since the winding drum 3 descends together with the winding drum mount 7 at a predetermined descending speed V, the portion of the outer peripheral surface 8 where the wire W is not wound is always lowered at the same height as the die 2. I'll come. Therefore, the wire rods W do not overlap, and the wire rods W are not bent at the portion where they pass through the die 2, so that the pass line P is always maintained in a straight line. In this way, when the tongs 9 have descended to the position indicated by the solid line in FIGS.
The position at which this wire W separates from the drum 3 and falls is determined by the touch rollers 11 .

The die box 46 is pivoted on a support shaft 47 so as to be able to swing up and down slightly, and its tip is received by a tip support member 48, and this support member 48 is held by a screw mechanism or the like. The direction of the dice box 46 can be slightly adjusted up and down by moving it up and down.

〔Effect of the invention〕

In this way, in the present invention, the winding drum 3 and the drive device 5
The winding drum mounting base 7 equipped with the deceleration device 4 and the die 2
Since the base 16 is configured to be movable up and down, it is not necessary to move the die up and down as in the conventional method (to have the die gripped by the tongs at the start). This has the effect that the line P does not fluctuate up and down. As a result, the wire W does not swing, so no measurement error occurs in the flaw detection device 19. Further, there is no need to make the flaw detection device 19 and the prefixing device 18 of special specifications (therefore, general-purpose devices can be used).

By preventing vertical fluctuations of the pass line P, the front-process equipment including the flaw detection device 19 and the pre-applying device 18, etc., and the post-process equipment such as the winding drum 3 and the die 2 are arranged close to each other. Therefore, it is possible to form a connected shape reliably, and the wire rod W can be run smoothly. especially,
There is an advantage that it is easy to ceratigize a wire W having a large diameter and a large weight.
