The present invention relates to a riveting device for manufacturing a rivet having a decorative effect attached to leather clothing, shoes, ornaments and the like.

In general, when manufacturing a rivet used in the same place as shown in Figure 4, after the head 110 and the leg 120 of the rivet 100, respectively manufactured separately, the legs of the rivet 100 The head and hand were welded to completion.

Therefore, the problem that the time required for the production of the rivets could not be automated was relatively increased. In addition, there is a problem that the price of the product rises due to the increase in labor costs along with the loss of productivity due to manual labor and the loss of manpower.

Accordingly, an object of the present invention is to provide a riveting device for automatically manufacturing the integrated body of the rivet head and leg portion attached to leather garments, shoes, ornaments, etc. to solve the above-mentioned problems. .

As a feature to achieve the object of the present invention as described above, the rivet bar wound on the swivel (driallumin, aluminum, copper, sulfur, etc., the rivet bar (rivet bar) by the transfer roller, the driving roller is cut to a predetermined length and riveted In the riveting apparatus for manufacturing a, comprising a cutting means for simultaneously forming the head portion of the rivet and the leg portion cut in both sides by simultaneously hitting the material cut to the predetermined length, the rivet by the means It is characterized in that it is configured to automate the production work.

Hereinafter, with reference to the accompanying drawings the technical configuration and preferred embodiments of the present invention will be described in detail.

In FIGS. 1 and 2, the material wound on the swivel 10 is transported by the feed roller 20 and the drive roller 30, cut to a predetermined length, and then priced with a hammer (not shown) to manufacture the rivet. In the device, the material 40 is cut to a predetermined length and then formed a head of the rivet at the price of a hammer (not shown) and at the same time the blade 91a at one end to cut the leg of the rivet on both sides ) And a cover 91 having a quadrangular protrusion 91b at the other end, a stopper 90 inserted into and fixed to the cover 91 to prevent rotation, and a stopper inserted into the cutter 91. Compression spring (90a) is fastened to one side of the (90), including a cutting means consisting of a locking plate (70b) and the insertion hole (70a) formed on the outer circumferential surface of the bush 70, leather, shoes, It is configured to automatically produce the rivets attached to the ornaments.

Reference numeral 93 is a control unit, 60 is a junction box, 50 is a guide rail.

1 is a state diagram showing the overall configuration that can explain a series of operations of the present invention.

2 is an exploded perspective view showing a cutting means for the main part of the present invention.

Figure 3 (a), (b) is an operating state diagram by the cutting means of the present invention.

As shown in FIG. 1 and FIG. 2, a rivet bar 40 of material (dullalumin, aluminum, copper, brass) is wound on top of the rotating swivel 10.

The material 40 is inserted into the device via a drive roller 30 which receives power from a drive motor (not shown) via an transfer roller 20 alternately formed on both sides.

That is, when the driving motor is operated by the operation of the control unit 93 while the power is applied, the material 40 wound on the swivel table 10 is rotated as the driving roller 30 receives the power. It is inserted into the device via the drive roller 30 through the (20).

As described above, the material 40 inserted into the device is cut to a predetermined length by a cutter (not shown) and a forceps (not shown) separately provided.

The tongs are inserted into the insertion hole 70a of the bush 70 while the cut material is bitten by the forceps.

In this case, as shown in FIG. 3A, the cut material 40 is inserted into the insertion hole 90a of the bush 70 so that one side is in contact with the blade 91a formed at the tip of the cutter 91. It becomes a state.

After that, the hammer 92 positioned in front of the bush 70 is inserted into the insertion hole 70a of the bush 70 and the part 40 protrudes from the protruded material 40. A 94a is formed and the material 40 injected into the insertion hole 70a of the bush 70 is cut by the blade 91a of the carter 91 to form the leg 94b.

At this time, the head 94a of the rivet 94 is formed like a half groove 92a provided in the front inner side of the hammer 92.

That is, at the same time as the price of the hammer 92, the head portion of the rivet and the cut leg portion are formed (see FIG. 3 (b)).

When the hammer is priced, the compression springs 90a and the elastic springs 80 embedded in the bush 70 are buffered when the cost is greater than the force required.

Thereafter, the hooks (not shown) located in the lateral direction are taken out of the rivet box 60 by moving the guide rails 50 along the withdrawal of the rivets.

This series of operations can be mass-produced as soon as they are completed in an instant. Also, automation can prevent the loss of manpower, thereby reducing labor costs and lowering the price due to mass production. There is this.

Claims (2)
