Technical Field

[0001] This invention relates to the field of steel wire hose clamp forming technology, and in particular to an automatic forming equipment for double steel wire hose clamps. Background Technology

[0002] Double-wire hose clamps are steel wire clamps that form a double-layered ring. Currently, the processing of double-wire hose clamps involves the following steps: first, the steel wire is cut to a suitable length using a cutting machine; then, workers use wire-threading clamps to fold the wire in half; finally, the two ends of the folded double-layered wire are bent into folded ears and hooks using bending tools; and finally, the entire clamp is bent into a ring shape. Most of this work requires manual intervention, resulting in low operational stability and inconsistent quality of the finished hose clamps. Furthermore, multiple machines are required for processing, with workers operating them one by one, leading to low automation. Summary of the Invention

[0036] The folding mechanism 3 includes an inner folding mold 31, an outer folding mold 32, and a second driving mechanism 33 that drives the inner folding mold 31 and the outer folding mold 32 to move toward each other.

[0037] The folding mechanism 4 includes a lower folding mold 41, an upper folding mold 42, and a third driving mechanism 43 that drives the lower folding mold 41 and the upper folding mold 42 to move toward each other.

[0038] The rotating mechanism 5 includes a first rotating mold 51, a second rotating mold 52, a fourth driving mechanism 53 for driving the first rotating mold 51 to rotate, and a fifth driving mechanism 54 for driving the first rotating mold 51 and the second rotating mold 52 to separate from each other. The first rotating mold 51 is provided with a hook 55 for locking the wire folding part.

[0039] The folding mechanism 6 includes a lower folding die 61, an upper folding die 62, and a sixth driving mechanism 63 that drives the lower folding die 61 and the upper folding die 62 to move toward each other.

[0040] In this embodiment, the steel wire is continuously fed into the frame 1. After passing through the cutting mechanism 2 for a certain distance, the first driving mechanism 24 drives the wire cutting block 22 to move in the first guide groove 23. The wire cutting block 22, together with the wire threading block 21, cuts the steel wire to prepare for the subsequent bending action. The second driving mechanism 33 drives the outer folding mold 32 to approach the inner folding mold 31. The outer folding mold 32 can hold both sides of the steel wire and, together with the inner folding mold 31, folds the steel wire. After folding, the third driving device drives the upper folding mold 42 to move downward, pressing the bent part of the steel wire against the lower folding mold 41 to deform and press out the steel wire ear. The fourth driving mechanism 53 drives the first rotating mold 51 to rotate, and the hook 55 holds the steel wire. The folded ear section drives the steel wire to rotate, and the tail of the steel wire can be held by the upper folding hook die 62, so that the steel wire can be turned into a loop; the lower folding hook die 61 is set on one side of the first rotating die 51 and the second rotating die 52, and the upper folding hook die 62 points to the gap between the lower folding hook die 61 and the first rotating die 51 and the second rotating die 52.

After the wire is cut, the folding operation can be performed directly. The inner folding mold 31 is mounted on the lower folding mold 41. After the wire is folded, the ear-folding operation can be performed directly. When folding the ear, the inner folding mold presses down on the wire and the inner folding mold 31, and the inner folding mold 31 will retract into the lower folding mold 41. After the wire is folded, the inner folding mold 31 is lifted, and the bent part of the wire will separate from the inner folding mold 31, which facilitates the subsequent movement of the wire.

[0054] The working process of this embodiment is as follows:

[0055] Cutting: The steel wire is passed through the wire-threading block 21 for a certain distance. The reduction motor drives the first rotating shaft 11 to rotate.

The first rocker arm 245 swings, driving the wire-cutting block 22 to move in the first guide groove 23 to cut the steel wire.

[0056] Folding: Simultaneously with cutting, the second swing frame 332 and the first swing frame 245 swing together. While the wire cutting block 22 cuts the wire, the outer folding mold 32 and the inner folding mold 31 cooperate to fold the wire in half.

[0057] Folding Ear: The first rotating shaft 11 rotates together with the second rotating shaft 12 and the third rotating shaft 15. The first rocker arm 241 returns to its original position first, and the outer folding mold 32 moves backward. The protruding part of the second cam 434 contacts the second rocker arm 433. The second rocker arm 433 and the third rocker arm 432 swing, driving the folding ear pusher 431 to move downward. The upper folding ear mold 42 and the lower folding ear mold 41 cooperate to perform the folding ear action on the steel wire.

[0058] Displacement: After the second swing rod 433 is reset, the upper mold 42 of the folding ear is raised, and the inner mold 31 pushes up the steel wire after the folding ear. Then, the protruding part of the fifth cam 744 contacts the fifth swing rod 743, and the fifth swing rod 743 and the seventh swing frame 742 swing accordingly, driving the pressing push rod 741 to move up and down. The pressing push rod 741 pushes the pressure plate 73 down to press on the pressure block, clamping the tail of the steel wire.
