Abstract

The present invention relates to a feeder for supplying material into a mold die as a part of a heading machine for a mold work.

In particular, the material (iron wire of appropriate thickness) pushed into the feed hole of the mold is passed through the upper and lower clutch rollers through the first, second and third rollers and fed into the mold die of the heading machine. It is a material supply device of a heading machine which blocks the retraction.

In the heading material supply apparatus of the prior art, when the cutting operation for cutting the material to a suitable size, the material is retracted and cut slightly smaller than the intended size.

This problem is caused by the structure of the power transmission device of the feed roller of the material reciprocating movement, which causes a greater deviation even if the machine is slightly aged.

Therefore, the material supply device of the present invention can improve the precision of the same size of the produced product by the constant amount of material introduced into the mold.

Description

Heading material feeder {input device of matters in heading machine}

The present invention relates to a feeder for supplying material into a mold die as a part of a heading machine for mold work.

In particular, the material (iron wire of appropriate thickness) pushed into the feed hole of the mold is passed through the upper and lower clutch rollers through the first, second and third rollers and fed into the mold die of the heading machine. It is a material supply device of a heading machine which blocks the retreat.

In general, a heading machine is a machine for producing bolts, nuts or various screws and pins by using a mold.

By the way, in the case of a material supply device that is conventionally used in such a heading device does not show a difference in configuration different from the present invention shown in Figure 3, but shows a lot of difference in terms of the effect.

That is, the material (iron wire of a suitable thickness) which entered the die frame of a heading machine by the 1, 2, 3 roller shown in figure is cut | disconnected to an appropriate size, and the shape is formed.

However, when a cutting operation for cutting to a suitable size, the material is retracted and cut to a somewhat smaller than the intended size occurs.

This is a problem in the conventional material supply device of the heading machine when the material is cut back to the appropriate size when the material is retracted and cut somewhat smaller than the intended size.

In particular, when manufacturing an article requiring precision, this phenomenon remains a bigger problem.

The present invention supplies the material (iron wire of appropriate thickness) pushed into the feed hole of the mold through the first, second and third rollers and passes through the upper and lower clutch rollers into the mold die of the heading machine. Want to block the retreat.

Figure 2 is a side view showing the side of the present invention

Figure 3 is a rear view showing the back of the present invention

The present invention relates to a material supply device for supplying a material (iron wire of a suitable thickness) which is a part of the heading machine and consists of the following configurations.

A thick plate-shaped frame 10 having a rectangular shape in which a supply port 11 for supplying the material 1 is fastened;

First, second, third rollers (12, 13, 14) rotatably fastened at regular intervals for conveying the material (1) on one side of the mold (10);

A retraction prevention part 20 which is fastened to one side of the mold 10, that is, to the other side of the supply port 11, to prevent retraction of the material 1;

The material 1 which is coupled and pushed into the supply hole 11 ′ of the supply port 11 is passed through the first, second, third rollers 12, 13, and 14 through the retraction prevention part 20. Supply the material, but the material supply device to prevent the phenomenon of the material is pushed.

The components of the retraction prevention part 20 for controlling the retraction of the material during the configuration are as follows.

A lower clutch roller 21 having a clutch bearing 21 'configured to allow only one direction of rotation therein;

Upper clutch roller 22 having a built-in clutch bearing 22 'rotatably fastened to a roller interlocking plate 23 having a guide groove 23' 'fitted to a guide protrusion 23' formed on the frame 10. ;

A pressure screw 26 which is screwed to the handle support 24 fastened to the upper portion of the roller interlocking plate 23 and rotates by an adjustment knob 25;

By the pressing action of the screw 26, the upper clutch roller 22 presses the material into the lower clutch roller 21 to be pushed into the mold, thereby preventing retraction.

The configuration of the present invention has been schematically described, and will be described in detail with the drawings shown below.

Figure 1 shows a plan view of the subject innovation, Figure 3 is a view showing a rear view of the subject innovation.

The material (1; iron wire of moderate thickness) which passed the supply hole 11 'of the supply port 11 of FIGS. 1 and 3 shown in FIG. 1, the 1st roller 12, the 2nd roller 13, and the 3rd roller ( 14) sequentially, passing through the rightmost retreat prevention portion 20 as shown in FIG.

The lower clutch rollers 21 of the retraction prevention part 20 are arranged on the same line as the first, second, third rollers 12, 13, 14, and the upper clutch rollers 22 are fastened to an upper portion thereof. have.

The fastening pattern is shown in detail in FIGS. 1 and 2, and the guide groove 23 is cut in the space formed by cutting the upper part of the mold of the present feeding device, but separated into a quadrangular shape in the form of a guide protrusion 23 ′. Insert the roller interlocking plate 23 constituted by

The upper clutch roller 22 is fastened to the side of the roller interlocking plate 23 in a rotatable form, and an upper side of the roller interlock plate 23 is provided with a pressurizing screw 26 supported by the handle support 24 to which the adjusting knob 25 is fitted. (Shown in Fig. 3).

Therefore, when the material comes in, the adjustment knob 25 is turned according to its proper thickness to lower the pressure screw 26.

By this pressing action, the pressing screw 26 presses the roller interlocking plate 23, which brings about an action that can firmly bite and feed the material sandwiched between the upper and lower clutch rollers 22 and 21.

However, an important point here is that the clutch bearings 22 'and 21' (shown in FIG. 1) are built in the upper and lower clutch rollers 22 and 21, respectively.

That is, the upper and lower clutch rollers 22 and 21, which rotate the material in the direction of the arrow and rotate the material in the direction of the arrow shown in FIG. It basically blocks the retraction in the reverse direction.

The upper and lower clutch rollers 22 and 21, which supply the material by tightly filling, have this effect because reverse rotation is impossible.

Since the amount of material introduced into the mold is constant, the size of the article to be produced is the same, thereby improving the precision.

Therefore, in the case of the article manufactured in the heading machine is attached to the device of the present invention can minimize the occurrence of defects.
