Technical Field

[0001] The utility model relates to the technical field of bed core frame molding, in particular to a steel wire bending device. Background Art

[0002] The wire frame of the spring core is an important part of the mattress and is usually made of high-strength steel wire. This frame is used to support the springs on the mattress and provide support, allowing the mattress to maintain its shape and provide comfortable support. The wire frame is generally strong and durable, and can effectively disperse the pressure of the body, improving the comfort and support of the mattress.

Through one device, the steel wire is straightened, cut to a fixed length, welded into a steel wire ring, and the steel wire ring is bent to a fixed length into a mattress steel wire frame in sequence, which occupies a small area and has a high degree of intensiveness. It can produce the mattress steel wire frame in an integrated manner at one time, greatly improving the production efficiency.

[0004] The above technical solution also discloses a steel wire rodless cylinder mechanism, and the specification states that "the steel wire rodless cylinder mechanism 3 is composed of four arc-shaped guide parts, each arc-shaped guide part includes a lower arc-shaped guide member 34 installed on the guide plate, and an upper arc-shaped guide member 31 is arranged on the lower arc-shaped guide member 34, and an arc-shaped guide groove for the steel wire to pass through is defined between the upper arc-shaped guide member 31 and the lower arc-shaped guide member 34." This method mainly relies on the wire feeding mechanism to feed the steel wire into the arc-shaped guide groove, but the two arc-shaped guide parts located below have a certain gap. When one end of the steel wire enters the arc-shaped guide groove, there is a possibility that it will break away from the arc-shaped guide groove from the gap and not enter the lower arc-shaped guide member on the left.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] refer to Figures 1 to 3 A wire bending device comprises a frame 1, a first clamping mechanism 2, and a second clamping mechanism 3. The frame 1 is provided with a horizontal driving unit 11, the first clamping mechanism 2 is connected to the horizontal driving unit 11, one end of the second clamping mechanism 3 is connected to one side of the frame 1, and the frame 1 is provided with a rotating driving mechanism 12 for driving the second clamping mechanism 3 to swing in a circle;

[0020] The steel wire passes through the first clamping mechanism 2 and the second clamping mechanism 3 in sequence; and one end of the steel wire is clamped by the second clamping mechanism 3 to perform circular swing;

[0021] When the second clamping mechanism 3 swings to the preset position, the first clamping mechanism 2 clamps the steel wire, and after the external cutting device cuts the steel wire, it drives the other end of the steel wire to move forward, and cooperates with the second clamping mechanism 3 to swing to the initial position, so that the two ends of the steel wire are opposite.

[0022] Under this design, the steel wire passes through the first clamping mechanism 2 and the second clamping mechanism 3 in sequence through the external wire feeding mechanism. When one end of the steel wire is located at the second clamping mechanism 3, the second clamping mechanism 3 clamps one end of the steel wire and drives the second clamping mechanism 3 to swing in a circle through the rotating drive mechanism 12. When the second clamping mechanism 3 swings to a preset position, the preset position here can be that the second clamping mechanism 3 swings to 300 degrees, the second clamping mechanism 3 stops swinging, at this time the first clamping mechanism 2 clamps the steel wire, and after the external cutting device cuts the steel wire, it moves forward driven by the horizontal drive unit 11, at this time the second clamping mechanism 3 continues to swing, and when the second clamping mechanism 3 swings to the initial position, that is, completes the 360-degree swing, the first clamping mechanism 2 is located behind the second clamping mechanism 3, at this time the two ends of the steel wire are just opposite to each other, completing the bending circle.

[0023] In this way, wire loops of different lengths can be collected, and the bending process of the wire can be controlled more accurately to ensure the quality and accuracy of the loops.

[0024] In this embodiment, the horizontal driving unit 11 includes a rodless cylinder 111 located on the frame 1 , a first slider 112 connected to the power output end of the rodless cylinder 111 , and the first clamping mechanism 2 is connected to the first slider 112 .

[0025] Specifically, the rodless cylinder 111 drives the first slider 112 to move along the length direction of the rodless cylinder 111, and drives the first clamping mechanism 2 to move forward or reset. It should also be noted that this embodiment is not limited to the rodless cylinder 111, and the operator can also choose to use methods such as oil cylinder, motor screw, synchronous belt module, etc. according to actual conditions.

[0026] Preferably, the first clamping mechanism 2 comprises a support plate 21 connected to the first slider 112 and a first pneumatic clamping jaw 22 connected to the support plate 21 .

[0027] In actual use, the first pneumatic clamp 22 clamps the wire, and the rodless cylinder 111 drives the first slider 112, thereby driving the support plate 21 to move the first pneumatic clamp 22 forward. The first pneumatic clamp 22 uses air pressure as a power source, which is simple and convenient to operate. The clamping and releasing actions can be achieved through air circuit control, and the clamping and releasing speeds are fast, and the cost is relatively low.

[0028] Preferably, the first clamping mechanism 2 further includes a lifting module 23, the lifting module 23 includes a lifting cylinder, the cylinder body of the lifting cylinder is connected to the support plate 21, and the first pneumatic clamp 22 is connected to the power output end of the lifting cylinder.

[0029] Specifically, the lifting cylinder is mainly used in the resetting stage. By setting the lifting cylinder, the first pneumatic clamp 22 can be driven to descend below the plane where the steel wire is located, and then the horizontal driving unit 11 drives the first pneumatic clamp 22 to reset. After the first pneumatic clamp 22 moves to the initial position, the lifting cylinder drives the first pneumatic clamp 22 to rise to the initial position. In this way, the first pneumatic clamp 22 can avoid other mechanisms and avoid collision.

[0030] In this embodiment, the lifting module 23 also includes a slide rail 24 connected to the support plate 21, and a second slider 25 connected to the slide rail 24. The bottom of the first pneumatic clamp 22 is connected to the power output end of the lifting cylinder, and one side of the first pneumatic clamp 22 is connected to the second slider 25.

[0031] In actual use, we found that if only the lifting cylinder is used for lifting, the movement of the first pneumatic clamp 22 is not smooth and will receive the vibration transmitted by the frame 1. Therefore, in order to avoid this problem, a slide rail 24 is set on the support plate 21, and one side of the first pneumatic clamp 22 is connected to the second slider 25 on the slide rail 24. The bottom of the first pneumatic clamp 22 is connected to the power output end of the lifting cylinder. The cooperation of the second slider 25 and the slide rail 24 ensures the smoothness of the lifting of the first pneumatic clamp 22.

[0032] In this embodiment, the second clamping mechanism 3 includes a swing arm 31 and a second pneumatic clamp 32. One end of the swing arm 31 is connected to the rotary drive mechanism 12, and the second pneumatic clamp 32 is connected to the other end of the swing arm 31. The rotary drive mechanism 12 drives the swing arm 31 to swing so that the second pneumatic clamp 32 swings in a circle. The frame 1 is also provided with a drive module (not shown in the figure) for driving the second pneumatic clamp 32 to clamp or release.

[0033] When one end of the steel wire is located at the second pneumatic clamp 32, the driving module drives the second pneumatic clamp 32 to clamp one end of the steel wire, and under the drive of the rotary drive mechanism 12, the swing arm 31 swings and drives the second pneumatic clamp 32 to swing in a circle to achieve wire bending.

[0034] It should also be noted that in other embodiments, the first pneumatic clamp 22 and the second pneumatic clamp 32 are not limited to use, and those skilled in the art can choose to use other clamps such as electric clamps, hydraulic clamps, vacuum clamps, magnetic clamps, etc. according to actual conditions.

[0035] In a specific embodiment, the rotation driving mechanism 12 includes a driving motor 121 connected to the frame 1 , a transmission module 122 connected to a power output end of the driving motor 121 , and the second clamping mechanism 3 is connected to the transmission module 122 .

[0036] The transmission module 122 includes a driving gear 1221 and a driven gear 1222, and the number of teeth of the driving gear 1221 is smaller than the number of teeth of the driven gear 1222; the driving gear 1221 is connected to the power output end of the drive motor 121, the driven gear 1222 is rotatably connected to the frame 1 and meshes with the driving gear 1221, and the second clamping mechanism 3 is connected to the driven gear 1222.

[0037] When in use, the driving motor 121 drives the transmission module 122 to operate, so that the transmission module 122 drives the second clamping mechanism 3 to operate. In a preferred embodiment, the transmission module 122 adopts a driving gear 1221 and a driven gear 1222. The driving motor 121 drives the driving gear 1221 to rotate, thereby driving the driven gear 1222 meshing with it to rotate. The driven gear 1222 transmits power to the second clamping mechanism 3, so that the second clamping mechanism 3 swings, and the number of teeth of the driving gear 1221 is less than the number of teeth of the driven gear 1222, thereby achieving a deceleration effect, ensuring that the length of the steel wire is fixed for each bend, and the bending process of the steel wire can be more accurately controlled to ensure the quality and accuracy of the bend.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
