Description

Technical Field

[0001] This utility model relates to the field of molybdenum wire bending technology, and in particular to an S-shaped molybdenum wire bending device. Background Technology

[0002] An existing S-shaped molybdenum wire bending and fixing device (publication number CN 222133262 U) involves activating a cylinder to move a rack back and forth, simultaneously engaging it on its surface. This rack meshes with a gear below a rotating ring, causing the rack to rotate. The rotating ring rotates accordingly, providing a limiting effect. The molybdenum wire is placed inside two bending shafts, which are positioned one behind the other. As the shafts rotate, the wire bends into an S-shape. The wire passes through rollers to the processing position. After processing, pulling a handle activates a wire cutter below to cut the wire. During rotation, a stop bar provides a limiting effect. An extended fixing shaft is located below the fixed shaft and is fixed to the upper worktable by two positioning bolts. Moving the upper fixing shaft adjusts the bending length of the molybdenum wire. However, this device is cumbersome to operate, has low bending efficiency, and affects processing progress.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-5 As shown, an S-shaped molybdenum wire bending device includes a support box 1, a sliding groove 11 is provided on the upper end face of the support box 1, and a bending mechanism for relatively moving and cooperating to perform S-shaped bending of the molybdenum wire is provided on the support box 1.

[0025] In this embodiment: the bending mechanism includes a support component, a bending component connected to the support component, and a rotating component for rotating the support component. The support component includes a support shaft 21 vertically disposed in the support box 1, and a turntable 22 fixed on the upper side of the support shaft 21; the support shaft 21 is rotatably connected to the support box 1.

[0026] The bending assembly has two circumferential locations on the turntable 22. The bending assembly includes a connecting rod 23 at the upper end of the turntable 22, and a connecting seat 24 at the other end of the connecting rod 23. The connecting seat 24 passes through the support box 1 and a bending template 25 is fixed at its upper end. A guide block 26 is fixed at the lower end of the bending template 25. When the rotating assembly drives the turntable 22 to rotate, the turntable 22 pulls the connecting seat 24 through the connecting rod 23 to move under the limit of the slide groove 11, so that the bending template 25 moves towards the middle position under the limit of the guide block 26 to bend and form the molybdenum wire.

[0027] The rotating assembly includes a gear 27 fixed on a support shaft 21, with a rack 212 meshing at its rear. A moving assembly is connected to the lower end of the rack 212, causing it to reciprocate. A connecting rod 23 is rotatably connected to the turntable 22 and the connecting seat 24 via a pin. The connecting seat 24 and the guide block 26 are slidably connected to the slide groove 11 on the support box 1. The moving assembly includes a reciprocating screw 29 and a sliding column 210 arranged in parallel. Supports 28 are provided at both ends of the reciprocating screw 29 and the sliding column 210. A servo motor 213 is connected to one end of the reciprocating screw 29. A movable seat 211 is mounted on the reciprocating screw 29 and the slide column 210. The movable seat 211 is fixedly connected to the rack 212. The reciprocating screw 29 is rotatably connected to the support 28. The movable seat 211 is threadedly connected to the reciprocating screw 29. The movable seat 211 is slidably connected to the slide column 210. The servo motor 213 drives the reciprocating screw 29 to rotate, which pushes the movable seat 211 to reciprocate under the limit of the slide column 210. This causes the rack 212 on the movable seat 211 to mesh with the gear 27 and rotate, thereby driving the support shaft 21 and the turntable 22 to rotate.

[0028] In this embodiment: the upper end of the support box 1 is fixed with limit posts 31 and positioning plates 32 on both sides of the bending template 25. The limit posts 31 are arranged in opposite directions. The limit posts 31 and positioning plates 32 are used to limit the placement of the molybdenum wire.

[0029] The working principle and usage process of this utility model are as follows: The molybdenum wire is placed between the limiting posts 31, with one end aligned with the positioning plate 32. The servo motor 213 drives the reciprocating screw 29 to rotate, which in turn pushes the moving seat 211 to move the rack 212 under the limit of the sliding post 210. During the movement, the rack 212 meshes with the gear 27 and rotates, which drives the support shaft 21 and the turntable 22 to rotate. The turntable 22 pulls the connecting seat 24 to move under the limit of the sliding groove 11 through the connecting rod 23, which moves the bending template 25 to the middle position to bend and shape the molybdenum wire.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
