Description

ROTATIONAL PROCESSOR FOR PROCESSING SPIRAL GROOVE ON ACCESSORY CHAIN}

The present invention is designed to produce various types of long, short pitch or intermittent spiral grooves on the surface of jewelry chains widely used as ornaments such as necklaces, bracelets, rings, cords for handbags, and interior decoration materials. It is a rotary machine that processes spiral grooves in jewelry chains. When machining spiral grooves in chains, the machine can turn the chain while turning the chain to enable continuous processing and at the same time provide diverse and good quality. It is designed for the purpose.

The spiral grooving machine of the conventional jewelry chain related to this field is a chain rotation bite which contacts and cuts the surface of a rotating chain while the workpiece chain is rotated and fed at constant speed simultaneously with rotation. It was fixed.

However, long chains cannot be machined, as the chain cutters for jewelry need to rotate the chain. In general, only chains within 5 m were possible. As the length of the chain is restricted, machining is interrupted, resulting in poor work efficiency and poor quality. In addition, only one fixed bite could be installed, which contributed to the low productivity.

The present invention is capable of continuously processing long chains of 5m or more in the form of single or double or double wires or intermittent spiral grooves on the surface of jewelry chains. The main task is to provide a rotary machine for machining spiral grooves in a dragon chain.

The above object is a chain guide tube arranged at the beginning of the chain in the feeding direction of the die and a tubular rotary shaft supported by the front and rear bearings, a rotary disk for the rotary shaft drive motor and a cutting machine attached to the rear end of the rotary shaft, It is achieved by a rotary machine for machining a spiral groove in a chain for ornaments consisting of a single or a plurality of cutters eccentrically mounted on a turntable and a cutting guide attached concentrically to the rear end of the rotary shaft.

Here, the cutting machine is mounted so that the bite band faces the front face of the bite in the helical direction of the spiral groove, and the cutting guide has an exposed portion 15 which exposes a chain to be processed in the area where the bite edge contacts. .

1 and 2, the spiral groove processing machine die 1 of the jewelery chain of the present invention, the chain guide tube (2) arranged at the beginning of the insertion direction of the chain in the die (1), the front and rear bearings (3) A rotating shaft 4 supported by the rotating shaft 4, a motor 5 for rotating the tubular rotating shaft 4 at high speed, a rotating disk 6 attached to the rear end of the rotating shaft 4, and a stage mounted on the rotating disk 6, or It consists of a plurality of cutting machines (7), cutting guides (8) attached on the concentric line at the rear end of the rear rotating shaft (4) of the rotary disk (6).

The rotating shaft 4 rotates at a high speed by the power of the motor 5 transmitted through the belt 9 to pivot the cutting machine 7 around the chain, thereby cutting the spiral groove on the surface of the chain with a bite mounted thereon. As the chain to be machined passes through the center thereof, the rotating shaft 4 is a tubular shaft.

Referring to FIG. 3, the rotary disk 6 is provided with one or a plurality of movable rails 10 around the rotating shaft 4. The rail 10 is useful for adjusting the distance between the chain and the bite by the perspective operation of the feed table 11 according to the thickness of the chain and the depth of the spiral groove. When installing a plurality of rails 10 are attached side by side on the opposite side at the center of rotation.

The movable rail 10 can be adjusted so that the cutting machine 7 is located near or far from the center of rotation of the rotary disk 6 by the adjusting screw 17 installed in the rail direction at the centrifugal end of the rotary disk 6. It is installed in the form.

The rail 10 is provided with a conveyer 11 in a form capable of advancing and retracting along its longitudinal direction, and a cutter 7 made of a motor 12 and a bite 13 is attached to the conveyer 11. When the blade line of the bite 14 mounted on the bite base 13 is placed at right angles to the conveying direction of the chain, the front side of the blade line does not cut the chain, but the front side of the blade line, that is, the side of the blade line coming to the chain touches the chain. Not cutting the chain, but scraping and tearing results in inefficient cutting and poor quality. Accordingly, the bite band 13 is installed at a predetermined angle with respect to the conveying direction of the chain to reliably cut the surface of the chain, which is conveyed linearly at a constant speed, so as to make a sharp spiral groove. Here, the predetermined angle means an angle at which the blade line of the bite is placed in front of the spiral groove direction of the chain being conveyed.

Another reason why the bite band 13 is to be squeezed as described above is that the bite 14 must selectively contact only the surface portion of the chain exposed by the exposed portion 15 drilled in the cutting guide 8. In other words, the bite 14 has to contact the chain only at certain points. Because the cutting guide 8 must support the machined chain that the rear end 16 has passed the cutting position to prevent the chain from shaking during subsequent cutting. Therefore, the rear end 16 is provided at the rear of the exposed portion 15 to support the processing chain without shaking. The rear end 16 is integrated with the cutting guide 8 via the connecting portion 17. In this structure, if the bite 14 has a concentric orbit around the cutting guide 8, it is unreasonable because the connection part 17 is cut off by the bite 14.

However, if the bite band 13 is stiffly installed on the exposed portion 15 of the cutting guide 8 as described above to rotate and revolve at the same time, as shown in FIG. Eccentrically mounted on the blade) rotates the revolution trajectory (S1) and at the same time rotates the rotation trajectory (S2) and the rotational speed of the chain (a) to match the revolution and rotation speed of the bite (14) of the bite (14) Since the grooves of the bite 14 do not come into contact with the connecting portion 17 because the spiral groove bet machining is performed in a state that the spiral groove betting operation is made in advance in the circumferential width center of the exposed portion 15 in advance. It is kept intact.

Arranged at the rear of the chain processing machine is a drawer 20 which is a workpiece for forcibly pulling and drawing a chain having a spiral groove, which is installed at the same height as the cutting guide 8 on the die 21 and the die 21. A pair of top and bottom rotary take-out rolls 22, a motor 23 for rotating the take-out roll 22, an adjustment screw 24 for raising and lowering the upper take-out roll 22 according to the thickness of the chain, and a chute. It is a general one consisting of 25.

With reference to the figure cited above, a brief description will be given of the process in which the spiral groove is machined on the surface of the chain (a). In the chain bobbin (not shown) provided in front of the chain processing machine, the tip of the chain (a) is released, inserted into the chain guide tube (2), and pushed continuously so that the tip is caught between the take-out rolls (22). Subsequently, the rotation speed of the turntable 6 and the bite base 13 and the take-out speed of the take-out roll 22 are adjusted so as to match the thickness of the chain, the pitch of the spiral grooves, and the number of the spiral grooves.

As described above, the chain (a) conveyed at a constant speed is each time the spiral of the bite 14 is rotated at the same time as the rotation while passing through the exposed portion 15, the spiral groove (b) is formed, thus the spiral groove (b) As a result of the cutting, the processed chain a1 is forcibly pulled out by the take-out roll 22 and the continuous output to the subsequent chain portion and the spiral groove b processing are performed by the pull-out force.

Figure 5 is a few examples of the spiral groove (b) that can be processed in the multi-machine cutting chain machine, Figure 5 (a) is a spiral groove formed by processing a long pitch when rotating the speed of the machine slowly 5, (b) is an embodiment of the spiral groove that is formed while the machine speed is rapidly rotated but the intermittent stop action is repeated, Figure 5 (c) is a spiral when the speed of the machine continues to rotate rapidly An embodiment of the spiral groove in which the groove is densely processed, FIG. 5 (d) is a cross-sectional view of (a), and FIG. 5 (e) is a cross-sectional view of (c). In addition, a single cutting machine can process single-threaded spiral grooves with long and short pitches.

As described above, the present invention is a spiral groove in a chain for jewelry, in which the chain is transported at constant speed and the bite rotates around the chain at the same time as it rotates, cutting only by touching and touching the exposed chain part only in the exposed part. This is a rotary processing machine that processes long chains of infinitely long lengths of 5m or more, which has been recognized as a limitation of the conventional machining length when cutting single or two or more spiral grooves. .

In addition, continuous spiral groove betting can lead to improved machining quality, resulting in a high quality spiral groove chain.
