Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a forming device for continuously bending lead terminals of circuit S products from two different directions.

A circuit component such as a capacitor or a resistor, which has a pair of lead terminals led out from the main body, is mounted on a printed board to form a desired electrical circuit. When inserted and inserted, the lead terminals are latched onto the printed board to prevent the circuit components from being removed, and the lead terminals are bent from two different directions in order to maintain the shape of the circuit components to some extent. Forming is widely practiced.

Figure 1 shows the capacitor before forming, and Figure 2 shows the capacitor before forming.
The figure is a perspective view showing an example of forming applied to the lead terminal of the capacitor. That is, as shown in FIG. 1, in a capacitor l manufactured by a normal general process, a pair of lead terminals 3 are led out from a main body 2 in a substantially straight line.

Therefore, the lead terminal 3 was processed with 7 overhangs and the second
As in the lead terminal 3' of a capacitor 1' shown in the figure, K forming a Z-shaped bend 4 and a U-shaped protrusion 5 is conventionally
The bend 4 was first formed by pressing in the direction, and after being conveyed to a predetermined position, the protrusion 5 was formed by pressing in the direction of arrow B. Therefore, the molding of the lead terminals 3' requires two cumbersome steps with an intermediate conveyance step.

The purpose of this invention is above &l! The purpose is to eliminate the trouble, and the purpose is to include a fixed block that is T-shaped in plan view, a pair of first movable blocks that reciprocate along the skeleton fixed block, and a pair of first movable blocks that reciprocate along the fixed block. This is achieved by providing a circuit component lead terminal forming device characterized by comprising a block and a second movable block that reciprocates in a different direction.

Hereinafter, main parts of the apparatus according to an embodiment of the present invention 9! The present invention will be explained with reference to FIG. 3, which shows a perspective view of the component structure, and FIG. 4, which sequentially shows its operation.

In FIG. 3, the lead terminal forming device 11 of the condenser tll shown in FIG. Slurped. Fixed block 12
Connect the capacitor (
1), and a lead terminal abutment 1116 on which one end of the saddle part 15 is fixed approximately at the center.
Partition walls 17 protrude from each other at a predetermined distance.

A protrusion 18 for forming a lead terminal protrusion 5 is formed protrudingly on the side surface of the abutment part 16 on the side from which the saddle part 15 protrudes.

Along the abutment 916 of the fixed block 12, the saddle WA
A pair of movable blocks I3 that reciprocate symmetrically in a straight line toward 15 have a saddle Ii@an upper sK protrusion 19 protruding at the tip. On the other hand, there is a suppression block 2 that moves straight forward along the saddle Ill 5, and the suppression block 22 protrudes and is formed with a recess s23 corresponding to the protrusion 18.

In such a device 11, the movable pulls 13 and 14 are operated by air cylinders (or cam mechanisms, etc.), and the operation is shown in FIG.

In FIG. 4(a), each movable block 13 and 14 (
14 (not shown) is retreated from the fixed block 12, and the condenser lFi shown in FIG. 1 and a pair of lead terminals 3' are placed so as to straddle the saddle.

Next, as shown in Fig. 4, a pair of movable blocks 13
After moving the lead terminal 302 toward the saddle 15 and forming the lead terminal 302-shaped bend 4, the movable block 13 is returned to its original position.

FIG. 4(c) shows the capacitor 1, fixed block 12, and movable block 1 after the movable block 13 has been operated as described above.
4, the movable block 14 moves forward toward the abutting portion of the fixed protrusion 12.

As a result, as shown in FIG. 4(d)K, the notch 20 of the movable block 14 cuts the pre-length of the lead terminal (3), and then protrudes between the protrusion 18 and the pressing block recess 23.
A U-shaped protrusion 5 is formed to sandwich a part of the lead terminal (3), the movable block 14 is returned, and the capacitor 1', which has been formed as shown in FIG. 2, is transported out. .

In addition, in the above example, the lead terminal of the capacitor is
Forming is performed and cutting is performed to a predetermined length, but when the above cutting is not required, a notch (20) is formed on the cutter to replace the sliding table (21).
Use a terminal that does not have a lead terminal and does not protrude below the lead terminal to be folded.

As explained above, according to the present invention, while forming the lead terminal of a circuit component from two different directions, one
Since the circuit components are not transported, the time required for assembly is shortened to approximately 1/2 of that of the conventional method, resulting in a significant improvement in work efficiency and the effect of miniaturization of the forming and mounting process.
