Description

Technical Field

[0001] The invention relates to a wire bending machine, in particular to a wire guiding device with an adjustable wire feeding path for the wire bending machine. Background Art

[0002] The wire bending machine (i.e., automatic wire bending machine) currently used to make springs generally includes a frame, a vertically distributed mounting disc on the frame, a mandrel fixed in the middle of the mounting disc, and a tool mechanism in which several tools can move, wherein one side of the mounting disc is a vertically distributed tool mounting surface; the mandrel is perpendicular to the tool mounting surface, and a wire path guide shaft hole is provided in the mandrel, and the wire path guide shaft hole is the wire feeding path (the wire feeding path is fixed); each tool mechanism is installed on the tool mounting surface and distributed in sequence around the circumference of the mandrel. When making the spring, the spring steel wire extends out under the guidance of the wire path guide shaft hole, and then is bent, curled, and cut by the tools of each tool mechanism on the tool mounting surface to realize the automatic production of the spring.

[0003] The core shaft of the current wire bending machine is fixed, that is, the wire feeding path is fixed; and there are many types of springs at present, among which various fancy springs and highly difficult special-shaped springs need to be bent at multiple angles and multiple locations. This requires not only adding multiple sets of bending forming tool mechanisms when making these complex springs, but also the replacement of tools may be involved during the production process, affecting the processing efficiency. On the other hand, when making different types of springs, due to different bending angles and locations, it is also necessary to adjust the orientation of the bending forming tool mechanism, which is inconvenient to operate. Summary of the invention

[0004] The purpose of the present invention is to provide a wire feeding path that can be adjusted and moved to adapt to the processing and manufacturing of complex springs that need to be bent at multiple angles and multiple locations; at the same time, it can also improve versatility and adapt to the processing and manufacturing of different types of springs for wire bending machines without adjusting the tool orientation. The wire feeding path can be adjusted.

[0034] Specific embodiment 1: Figure 1 , Figure 2 As shown, a wire guide device with an adjustable wire feeding path for a wire bending machine includes a frame, a wire path guide assembly and a wire path movement adjustment device. The wire path guide assembly 2 includes a core shaft 2.1, and the core shaft is horizontally distributed. A wire path guide shaft hole 2.2 is provided in the core shaft, and the wire path guide shaft hole is coaxially distributed with the core shaft, and the wire path guide shaft hole passes through the core shaft, and the wire path guide shaft hole constitutes the wire feeding path of the wire bending machine.

[0035] The wire path movement and adjustment device includes a wire path X-axis movement mechanism 3, a wire path Z-axis lifting mechanism 4 and a wire path Y-axis movement mechanism 5. The wire path X-axis movement mechanism 3 is used for the core shaft to move along the X-axis direction, and the X-axis direction is parallel to the axial direction of the core shaft. The wire path Z-axis lifting mechanism 4 is used for the core shaft to move up and down in the vertical direction. The wire path Y-axis movement mechanism 5 is used for the core shaft to move along the Y-axis direction, and the Y-axis direction is perpendicular to the X-axis direction. In this embodiment, the Y-axis direction is horizontally distributed. Specifically, the wire path X-axis movement mechanism 3 includes a transverse guide rail 3.1 arranged on the frame, a transverse slide 3.2 sliding along the transverse guide rail and a transverse drive mechanism for driving the transverse slide to move. The transverse guide rail is horizontally distributed. The transverse guide rail is parallel to the axial direction of the core shaft. A wire path mounting member 7 is provided on the transverse slide. The wire path Z-axis lifting mechanism 4 includes a vertical guide rail 4.1 arranged on the wire path mounting member, a lifting slide 4.2 lifting along the vertical guide rail, and a lifting drive mechanism for driving the lifting slide to move up and down. The wire path Y-axis moving mechanism 5 includes a longitudinal guide rail 5.1 arranged on the lifting slide, a longitudinal slide 5.2 sliding along the longitudinal guide rail, and a longitudinal drive mechanism for driving the longitudinal slide to move. The longitudinal guide rail is horizontally distributed. The longitudinal guide rail is perpendicular to the transverse guide rail. The mandrel is installed on the longitudinal slide.

[0036] The mandrel of this embodiment can be adjusted in the X-axis direction, Y-axis direction and vertical direction through the wire path moving adjustment device, so that the wire path guide shaft hole (the wire path guide shaft hole is the wire feeding path) provided in the mandrel can be adjusted and moved in a large range in the front, back, left, right, up and down directions to adjust the position of the spring wire to adapt to the production of complex springs that need to be bent at multiple angles and multiple locations, and it is beneficial to reduce the number of bending forming tool mechanisms. At the same time, it can avoid the possibility of tool replacement during the production process, which is beneficial to improve the processing efficiency of complex springs. On the other hand, it can also improve versatility. Without adjusting the orientation of the tool mechanism, by adjusting the position of the wire path guide shaft hole, it can adapt to the processing and production of different types of springs.

[0037] Specifically, Figure 1 , Figure 2 As shown, a vertically distributed mounting cutter disc 1 is provided on the frame. A mandrel opening 1.1 is provided on the mounting cutter disc.

In this embodiment, the wire path mounting member is a wire path mounting plate, and the wire path mounting plate is parallel to the cutter disc.

[0039] Further, such as Figure 1 As shown, the wire guide device with adjustable wire feeding path for the wire bending machine also includes a mandrel rotating mechanism 6. The mandrel rotating mechanism is used to drive the mandrel to rotate, and the rotation axis of the mandrel coincides with the axis of the mandrel. In this way, the mandrel can be driven to rotate by the mandrel rotating mechanism to adjust the orientation position of the half-cut notch at the output end of the mandrel, which is conducive to adapting to the working needs of bending forming tools in different positions.

The transverse screw rod is parallel to the transverse guide rail. The transverse driving mechanism adjusts the position of the transverse slide by the screw rod and nut mechanism, and its adjustment accuracy can be ensured. Of course, the transverse driving mechanism can also be replaced by a linear module, an electric push rod or an electric cylinder.

[0042] The lifting drive mechanism includes a vertical screw rod 4.3 rotatably arranged on the wire path mounting member, a lifting nut 4.4 fixed on the lifting slide and matched with the vertical screw rod, and a lifting motor 4.5 arranged on the wire path mounting member for driving the vertical screw rod to rotate.

Of course, the longitudinal drive mechanism can also be replaced by a linear module, an electric push rod or an electric cylinder.
