In the present invention, the manufacturing apparatus for forging and molding a fastener component such as a rivet, a bolt screw, or an electronic component such as a lighter nozzle or a reel shaft in the form of a soft type (the form of hitting both sides in succession) is driven. 2Y which alternately ascends and descends by the link installed on the cam rail of the gear in the form of a year (type that strikes both sides in succession) alternately ascends and descends by the link installed on the cam rail of the driven gear. It is possible to achieve the reduction of manufacturing cost and maximize the installation space by improving the product precision and the length of the machine by minimizing the length of the machine according to the improvement of productivity and the accuracy of the blow compared to the conventional general machinery. will be.

In general, a conventional mechanical device that is forged by hitting fastener parts or electronic parts is mainly installed by the rod that is connected to the crank arm of the main shaft after installing a blow mold that is raised and lowered only on one side of the carriage. Each time the reciprocating motion causes the fixed die to be blown once, so the work efficiency is low and the productivity is low compared to the working time, and such a device is not declared as a utility model registration. 17401 (notice 79-1848), 17720 (notice 80-61), 19936 (notice 80-771), and 22642 (notice 82-1547).

In order to further improve the production efficiency as described above, two rods are placed on one crankshaft facing each other, and two carriages on which the striking dies are installed are opposed to each other and the workpieces of the fixed dies formed on both sides of the machine body are removed. As a design designed to be blown in succession alternately, there is also a utility model registration No. 47269 (notice No. 90-595) of the applicant of the present application, but it must be installed in two separate carriages and each rod must be installed to operate them. As a result, the manufacturing cost is high and the length of the machine body is considerably long, so there is a problem that it cannot be installed in a narrow workshop.

The present invention has been invented in view of such a point and will be described in detail with reference to the accompanying drawings.

Two carriages each provided with a striking mold are each spoke to a rod opposed to the crank of the main shaft 14 so as to alternately strike the workpieces 25 and 25a of both fixed dies 3 and 3a. On the outer surface of the driven gear 4 meshed with the main gear 2, the cranks 19 and 19a of the cutting blades 17 and 17a and the operating cam plates 18 and 18a are opposed to each other. A cam rail 5 is formed on the inner surface of the gear 4 so that both cam rollers 8 and 8 a of the link 6 with the long hole 7 formed in the center are grounded, and both levers of the link 6 are grounded. (9) (9a) is provided with a striking mold 10, 10a to be alternately raised and lowered alternately on one end of the carriage 12, and the center of the carriage 12 is a hole (Hole: 13 to form a sliding hole 16 which is operated by being fitted to the cam 15 of the main shaft 14, and the two sides 16 'and 16 "are brought into contact with both inner surfaces of the hole 13, Sliding port 16 can be raised and lowered at the bottom The lock spaces 13a and 13b are formed, and at the other end of the driven shaft 20, the double cams 22 and 22a for operating the two side hitting rods 21 and 21a and the crank rod 23 for the wire bead ( In the drawing, the reference numerals 25 and 25a in the drawing are the work pieces obtained by cutting the steel wires 26 and 26a entering the machine body 1 to a predetermined length. (27) and (27a) are links of the striking plates (21) and (21a), and (28) and (28a) are coaxial with feed rollers (29) and (29a) for entering the steel wires (26) and (26a) at a predetermined length. (30) (30a) is a control tool for rotating the ratchet gears (28) (28a) by the crank rod (23) (23a) for the wire feed, and (32) is a motor (33) ) Is a pulley that transmits the same distance to the main shaft (14).

In this invention, both side surfaces 16 'and 16 "of the sliding hole 16 in the hole 13 of the carriage 12 are in contact with the inner surface of the hole 13, and the The upper and lower spaces 13a and 13b are formed so that when the main shaft 14 is rotated and the eccentric cam 15 is operated up or down as shown in FIG. 4 (a), it is pushed by the cam 15. The egg slide 16 is only lifted and lowered into the space 13 and 13b, and its operation does not reach the carriage 12. At this time, the carriage 12 is fixed to both sides of the fixed die 3 (3a). ), The side surface 16 'of the sliding hole 16 pushed by the cam 15 is the main shaft 14 when the cam 15 is operated to the left as shown in FIG. 4 (b). The carriage 12 is moved to the left side by a length away from the left side so that the left strike mold 10 is blown, and when the cam 15 is operated to the right as shown in (c) of FIG. Of the other side 16 "away from the main shaft 14 The bag 12 is moved to the right so that the right striking mold 10a hits the work, and both striking molds 10 and 10a of the carriage 12 are rotated in one rotation of the main shaft 14, respectively. The blow work is to be done one by one.

At this time, both cam rollers 8 and 8a of the link 6 are in contact with the inner cam rail 5 of the driven gear 2 and the driven gear 4 having a rotation ratio of 2: 1, and the link 6 Since the long hole 7 is formed at the center of the rod), the link 6 which is moved to the left and right according to the rotation of the cam rail 5 does not touch the driven shaft 20 and operates only the two levers 9 and 9a. The one-time reciprocating of the stage 12 is to raise and lower the blow mold (10) (10a) installed at both ends once each opposite to each other.

In the operation process of the present invention as shown in FIG. 4 (a), the workpiece 25 having the steel wire 26 cut to a predetermined length by the cutting blade 17 is moved to the left fixed die 3, and the right fixed die ( 3a), the upper mold of the right blow mold 10a is first molded into the workpiece 25a cut and supplied to the predetermined length by the cutting blade 17a, and then the cam 15 of the main shaft 14 is upward. And the cam rail 5 of the driven gear 4 moves the link 6 to the right from the state in which the carriage 12 is in the neutral position of both fixed dies 3 and 3a. As shown in a), the left impact die 10 of the carriage 12 is lowered so that the upper die coincides with the fixed die 3, and the right strike die 10a coincides with the fixed die 3a of the lower die. If the detailed description from the elevated state as follows.

The time when the link 6 of the driven gear 4 lowers the left striking mold 10 of the shuttle 12 and raises the right striking mold 10a is 1 /. It continues to be maintained for two revolutions. During this time, when the cam 15 of the main shaft 14 rotates to the left as in the fourth (a) degree state and the fourth (b) degree state, the sliding hole 16 is the carriage. (12) to the left so that the upper mold of the left blow mold (10) causes the workpiece 25 of the fixed die (3) to be primary-formed, and the main shaft (14) and the cam (15) continue to rotate. As shown in FIG. 4 (c), when the carriage 12 is retracted to the right, the lower mold of the right striking mold 10a secondaryly forms the primary molded workpiece 25a of the fixed die 3a. .

Thereafter, as shown in FIG. 4 (d), when the carriage 12 is moved to the left by the rising of the sliding hole 16, the cam 22a built on the driven shaft 20 is struck with the striking rod 21a. 27a) is operated to take out the molded object 25a of the stationary die 3a by the operation, and at the same time, the link 6 is moved by half rotation of the driven gear 4, and the lever is moved. (9) The positions of the two side strike molds 10 and 10a addressed to 9a are in a state of being interchanged with each other as shown in the fourth (d).

In this state, while the cam 15 is rotated once again by the action of the sliding hole 16, the main shaft 14 is rotated again. As shown in Fig. 2, the primary molded workpiece 25a of the fixed die 3 is secondly molded and the wire 26a is cut to a predetermined length by the cutting blade 17a on the empty right fixed die 3a. Immediately after the workpiece 25a is moved and the first strike ready state, the carriage 12 is reversed and left fixed when the right strike mold 10a primaryly forms the workpiece 25a of the fixed die 3a. The secondary molded workpiece 25 of the die 3 is pulled out by the operation of the striking rod 21.

Then, as the link 6 is moved by the 1/2 rotation of the driven gear 4, the striking mold 10 of the carriage 12 is lowered and the striking mold 10a is raised again, and the fourth (a) is also achieved, the new die 25 is moved to the fixed die (3) on the left side of the empty, so that the above-mentioned operation process is repeated, both sides of the mold 12 of the carriage 12 (10a) is to perform the primary molding and the secondary molding of the workpieces (25, 25a) of the fixed die (3) (3a) in succession.

As described above, the present invention doubles the production amount compared to the mechanical device hitting only one side, since the finished products are blown one by one in succession every time the main shaft 14 is rotated two times. In particular, the cam of the main shaft 14 installed in the central hole 13 without the conventional cranks or rods, and then installed two striking molds 10, 10a at one end of the carriage (12) 15) and the sliding hole 16 is smoothly reciprocated horizontally without flowing the carriage 12, so that the blow is high accuracy can be molded more precisely, as well as the length of the machine body 1 Compared to the soft machine, it is considerably smaller and its structure is simpler, so it is cheaper to manufacture and install.
