A forming apparatus for forming a screw.

Generally, the member is coupled to the main body by a clip or a wire connector. Such clips are mainly used in automobiles and wire connectors are used for the construction or assembly of electrical materials that are coupled to other electrical wires.

Therefore, if screws are formed by screwing clips or wire connectors, the assembly performance is excellent and the performance of the product is excellent. In forming screws in clips or wire connectors, it is common to form thread tabs by drilling, mainly after drilling, bending and cutting processes.

According to such a general forming method of the clip and the wire connector, because the thread tab is formed after bending and cutting, the bending surface is bent by the drilling process during tab formation. In addition, since the clip and wire connector are small in size, they are not easy to be fixed to the fixing device. Even if the fixing device is stably fixed to the fixing device, drilling is not easy by the fixing device. In the following, there is a disadvantage in that the profitability of parts is low due to low unit cost.

For this reason, most drilling is done manually by the operator using a small drilling machine. Therefore, since the thread forming position, the thread forming form, and the force acting on the thread forming are different for each diameter, the products produced are not uniform. There is a problem that automatic assembly is impossible during the assembly process.

In particular, in the case of clips, the interval between the upper part and the lower part should be constant.

According to the present invention forming apparatus (1), in particular by the formation of the guide groove 65 of the guide plate 66 and the screw formation of the tab rotating frame 70 and the configuration of the fixing key 75, 2mm, 3mm, Various sizes of tap processes, such as 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, and 14 mm, can be performed. In particular, the formation of the guide plate 66 and the tab rotating frame 70 is easy in the process of forming tabs having small sizes such as 2 mm, 3 mm, 4 mm, and 5 mm, but in the formation of 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, and the like. The difference between the material of the member and the shape of the guide groove 65 and the total conveying distance is to ensure accurate operation, and thus the degree of precision machining is determined.

In particular, in the case of the clip 110, most of the produced is an excellent effect in the assembly process for automobiles. In other words, after assembling the clip to the part to assemble the car parts, and assembled to the car body, the clip produced by the forming apparatus 1 of the present invention, after forming a tab on the clip, the tab is bent or cut because The shape of the clip does not change according to the formation, especially during bending and cutting, because the bending and cutting in the state fixed to the "bending support" inside the clip, the vertical gap ("a" in Figure 7) of the clip is always constant Therefore, no assembly failure occurs. In other words, if the gap between the top and bottom of the clip is too wide, the previously inserted clip is separated from the part, and assembly failure occurs. If it is too narrow, it is not easy to insert the clip into the part. Although it is not easy to do, according to the present invention, since a constant interval (a) is always maintained, the manpower and time required for the inspection are not required separately, and there is an advantage in that productivity is improved because no assembly failure occurs.

In addition, as in the production of wire connectors, since the sizes of the wire connectors for 30A and 50A are different from each other, wire connectors of a suitable capacity must be manufactured. The size of the wire connector is not determined by the amount of current flowing or the thickness of the wire to be connected, but most of the size has been determined according to the size of the tab for forming the tab in the wire connector. In other words, in the past, since the tabs were formed after the holes of the wire connectors were formed and bent, the size of the wire connectors had to be determined according to the depth at which the ends of the tabs had to enter the wire connectors. However, according to the present invention, since the tab is first formed before bending and cutting, the height (“f” in FIG. 6) of the wire connector can be suitably provided according to the thickness of the wire or the current flowing by the tab. Accordingly, there is an advantage such as reducing the material costs because it does not need to be unnecessarily long.

Thus, as the size of the screws formed on the clip or wire connector is manufactured in various sizes such as 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 14mm, the size (thickness) of the tab 61, induction The size of the plate 66, the size of the guide groove 65, the size of the horizontal moving member 69 and the length and thread pitch of the male screw of the tab rotating frame 70 and the tab 61 should be adjusted accordingly. In general, it is preferable that the case of 5 mm or less and the case of 6 mm or more are formed differently in contrast.

That is, the size of the guide plate 66 is preferably about 170mm when the diameter c is 5mm or less, and about 178mm when 6mm or more. In other words, it is to be stable to the transfer of force in accordance with the size of the guide plate (66). In addition, it is preferable that the upper and lower lengths d of the guiding groove 65 are formed to be about 4 mm longer when the upper and lower lengths d are 6 mm or more than 5 mm or less. And when the length (b) of the horizontal movable member 69 is also 5mm or less, it is preferable that the length (b) is about 90mm, about 6mm or more is about 112mm. In addition, it is preferable that the size e of the shaft diameter of the eccentric shaft of the guide plate 66 is about 20 mm for 5 mm or less, and about 25 mm for 6 mm or more. In addition, the size (g) of the tab and the size of the female screw of the tab rotating frame 70 and the male screw of the tab were the general size according to the size of each tab.

In this way, since the size of each component is determined by working according to the size of the tab formed in the clip or wire connector, it is possible to manufacture a clip and wire connector of a more standard size.

The present invention provided as described above is to produce a clip and wire connector, such as through the punching, press molding, bending and cutting process of a continuous plate-shaped metal strip, in particular tabs are formed because the tab is formed before the bending and cutting process Since the formation of the part is uniform, the assembly is excellent, thereby reducing the production manpower and production time, such as the need for post-production inspection, and also has the effect of less generation of defects after assembly. In particular, there is an effect such that the production efficiency is increased by forming a tab of a large size of 6mm or more.
