Description

As shown in the figure, the two movable components are respectively arranged on the upper half and the lower half of the processing surface (102), and partially surround the wire guide (103) located in the center of the processing surface (102). Here, the movable component located in the lower half will be described. The movable component includes a first platform (201) and a second platform (202). The first platform (201) is movably connected to the processing surface (102), so that the first platform (201) can reciprocate along a first direction relative to the board (101), such as along the X direction as shown in the figure. The second platform (202) is movably connected to the first platform (201), so that the second platform (202) can reciprocate along a second direction relative to the board (101), such as along the Z direction as shown in the figure. The movable connection can be achieved by known rail means. Although not shown, the movable component should include a driving device for automatic control. As shown in the figure, the second platform (202) is provided with a fixed surface for installing one or more tools or devices.

In order to realize the three-axis operation of the spring manufacturing machine, the present invention provides a tooling device (300) fixed on the second platform (202). The tooling device (300) provides operations different from the aforementioned first direction and second direction (as shown in the Y direction) and can switch the tooling operation. One or more tools for forming the spring are mainly installed in the tool device (300), so that the tools can move three-axis relative to the plate (101) or the wire guide (103).

The third, fourth and fifth figures show different views of the tooling device (300). The tooling device (300) includes a body (301), which has an end portion (302), a fixing portion (303), a first side (304) and a second side (305). The end part (302) is opposite to the fixing part (303), and the first side (304) and the second side (305) are opposite and extending between the end part (302) and the fixing part (303). In this embodiment, the main body (301) is substantially a rectangular structure, and the fixing portion (303) has a structure suitable for being installed on the second platform (202) and can be fixed in a known manner. The end (302) is basically a free end that is not connected to other structures. The first side (304) is parallel and opposite to the second side (305), and perpendicular to the X direction. In other words, the first side (304) and the second side (305) are parallel to the XZ plane. The main body (301) is a housing for accommodating a movable mechanism for operating the device. As shown in the figure, the driver related to the operation of the device can be placed under the body (301) to avoid interference with the formation of the spring.

A first movable portion (306) is located on the first side (304) and is movably coupled to the main body (301). The first movable part (306) is configured to be able to move back and forth along a first direction relative to the main body (301). A second movable portion (307) is located on the second side (305) and is movably coupled to the main body (301). The second movable part (307) is configured to be able to move back and forth along a second direction relative to the main body (301). The first movable part (306) and the second movable part (307) are also configured to move synchronously, but their moving directions are opposite. The first and second directions of the tooling device discussed here are different from the first and second directions related to the platform, especially the first direction and the second direction here are parallel but opposite, which will be described in detail later .

The first movable part (306) and the second movable part (307) have a similar structure. The first movable part (306) and the second movable part (307) are respectively provided with a first fixed surface (308) and a second fixed surface (309) for mounting at least two processing components on the first part of the body (301). Side (304) and second side (305). As shown in the third figure, the first fixed surface (308) of the first movable portion (306) has a plurality of holes and grooves for fixing the working tool components. In this embodiment, the holes and grooves used for fixing are extended and arranged according to the Y direction, thereby determining the Y direction movement range of the tooling assembly.

As shown in the fourth figure, the first movable portion (306) and the second movable portion (307) respectively have a first shoulder (310) and a second shoulder (311), which are from the first side (304) ) And the second side (305) extend to a top (not numbered) of the main body (301) and partially cover the top of the main body (301). As shown in the second picture As shown, the first shoulder (310) and the second shoulder (311) are respectively provided with a third fixing surface (not numbered) and a fourth fixing surface (not numbered) for mounting at least two processing components. Similarly, the third and fourth fixing surfaces have holes and grooves for fixing. Since the first fixed surface and the third fixed surface of the first movable portion (306) are perpendicular to each other, the second fixed surface and the fourth fixed surface of the second movable portion (307) are perpendicular to each other, and the first fixed surface and the second fixed surface are perpendicular to each other. The distance between the surfaces is greater than the distance between the third fixing surface and the fourth fixing surface, and the installation of the tooling components will not interfere with each other.

The first and fourth diagrams clearly show the state where the tool kit is installed. That is, the first fixed surface (308) of the first movable portion (306) is fixed with a first tooling component (401), and the first shoulder (310) is fixed with a second tooling component (402). A third tooling component (403) is fixed on the second fixing surface (309) of the second movable part (307), and a fourth tooling component (404) is fixed on the second shoulder (311). In this embodiment, the first tool adding component (401) and the third tool adding component (403) are active tools, meaning that they need to be controlled by the driver. The second tool adding component (402) and the fourth tool adding component (404) are passive tools, meaning that they do not need to be controlled by a driver. Similarly, the driver is also arranged under the body (301). Of course, the combination of tool components is not limited to what is disclosed in the drawings.

The fourth figure shows that the first movable part (306) and the second movable part (307) are slidably connected to the main body (301) via a rail means. The inner surface of the first movable portion (306) is provided with a pair of structures corresponding to the rails (not numbered) on the main body (301), which are configured to restrict the displacement of the first movable portion (306) in the X and Z directions, so the first movable The part (306) can only move along the Y direction. The second movable part (307) also has a similar configuration. In other embodiments, alternatively, the sliding connection may also include a combination of wheels and rails.

The first movable part (306) and the second movable part (307) of the present invention are coupled via a transmission assembly, so that the first movable part (306) and the second movable part (307) can synchronously and reversely move back and forth. The fifth figure shows a cross-sectional top view of the main body (301) and the transmission assembly. A rotating shaft (312) is firmly accommodated in the main body (310) and configured to rotate along the XY plane. The rotating shaft (312) is connected with the driver to perform clockwise and counterclockwise rotation. The fifth figure also shows that the first movable portion (306) has a first rack (313), and the second movable portion (307) has a second rack (314). The racks (313, 314) are respectively fixed to the inner sides of the movable parts (306, 307) and extend along the Y direction. The first rack (313) is opposite to the second rack (314) and clamps the rotating shaft (312). The rotating shaft (312) is configured to mesh with the racks (313, 314), so that when rotating, the first rack (313) and the second rack (314) can be pushed synchronously by the rotating shaft (312), but the direction in contrast. The rotating shaft can be similar to a gear. In this embodiment, the first rack (313) and the second rack (314) are configured to have a displacement path in the Y direction, so that when one of the movable parts reaches a termination point of the Y direction displacement path, the other A movable part reaches the relative end point of displacement in the Y direction. Accordingly, a maximum distance can be maintained between two adding tools. In other possible embodiments, one or more rotating shafts may be used to drive the rack.

As in the foregoing configuration, according to the rotation of the rotating shaft (312), there is a minimum distance and a maximum distance between the first movable portion (306) and the second movable portion (307). In one embodiment, when one of the movable parts starts to move from the fixed part (303) of the main body (310) to the end (302), or vice versa, the other movable part approaches the movable part in the opposite direction until there is one The minimum distance means the same position of the two in the Y direction (for example, approximately in the middle of the body). After reaching the minimum distance, the movable part moves in the opposite direction until it is far away to the maximum distance, which means that the first movable part (306) and the second movable part (307) are respectively located at the two terminal ends of the moving path. In other words, except for the minimum distance relationship, the relationship between the movable parts (306, 307) is a tandem relationship in the Y direction. As shown in the second figure, one of the movable parts is relatively close to the wire guide (103) of the plate (101), that is, enters a processing position of the wire. The processing position refers to the position where the tool is in contact with the wire.

Referring back to the third and fourth figures, it shows that both sides of the main body (301) have an opening (not numbered) for the racks (313, 314) of the movable parts (306, 307) to enter the main body (301) and It meshes with the rotating shaft (312). The length of the opening in the Y direction determines the movable range of the movable portion (306, 307). The opening can extend to the end (302) of the main body (301), so that the movable portion (306, 307) can be separated from the main body (301) from the end (302), facilitating replacement or maintenance. In other possible embodiments, the transmission assembly can be implemented by other mechanisms, such as the use of rollers and belts.

Based on the foregoing configuration, the spring manufacturing machine of the present invention can execute a method including the following steps to achieve the purpose of quickly switching tools. This eliminates the need to reset the position of the tool, which improves the efficiency of the machine.

In order to manufacture one or more kinds of springs, first, the wire guide (103) is used to continuously provide a wire on a processing surface. The wire guide device and a bundle of wires are connected upstream of the wire guide. The wire guide can be configured to continuously discharge the wire at a specific speed, or discharge a specific length of wire at a specific cycle.

Then, based on a first structure to be formed into the spring, a first tool is used to shape the wire. As shown in the sixth figure, the first platform (not shown) and the second platform (202) are moved to appropriate positions, and the first movable part (306) of the tooling device is brought close to the wire guide (103), thereby The first tool installed with the first movable part (306) can enter a processing position of the wire. The first machining tool mentioned here is the aforementioned second machining tool assembly (402). In addition, the first adding tool is a wire reel, which forms the wire into a spiral structure until the first adding tool exits the processing position or stops the wire from advancing.

After forming the first structure (the spiral structure in this embodiment), a second tool is used to shape the wire based on a second structure to be formed into the spring. This means switching from the use of the first addition tool to the use of the second addition tool. As shown in the seventh figure, the first platform (201) and the second platform (202) move to The first movable part (306) of the tooling device is kept away from the processing surface (102), and the second movable part (307) is synchronously approached to the processing surface (102), so that the installation on the second movable part (307) The second tool can enter the processing position of the wire. The second machining tool mentioned here is the aforementioned third machining tool assembly (403). Moreover, the second tool is a bender, which can form at least one bend of the wire until the second tool exits the processing position or stops the wire from advancing.

It should be understood that, according to different settings, the processing positions related to the first adding tool and the second adding tool may be the same or different. The switching of the first platform and the second platform and the adding tool can be performed at the same time or at different times. As shown in the figure, the tooling device of this embodiment is equipped with four tooling components. In other words, according to this embodiment, at least four tools can participate in the formation of the spring. Those skilled in the art and technicians can determine the number and types of tools to be assembled in the tooling device of the present invention according to the design of the spring, and the plan for using the tools.

It is straightforward to note that since the first and second tools are configured to move synchronously and oppositely along the direction (Y direction) perpendicular to the processing surface (102), the machine can easily switch between locations. The necessary tools are not necessary to concentrate the possibly used tools on the board (101), and the area availability of the board (101) is also improved. As for the movable component in the upper half of the first figure, it can be assembled or replaced with a cutting tool for separating the formed spring from the wire. It should be understood that the tooling device of the present invention is not limited to be installed in the position shown in the figure.

Based on the above description, the spring manufacturing machine of the present invention provides an axial movement mechanism perpendicular to the processing surface compared to general spring manufacturing machines. This results in the arrangement of tools not limited to the plane of the board (XZ plane). Moreover, the reverse reciprocating mechanism provided by the tool adding device of the present invention makes the switching of the tool adding more convenient. The tooling device of the present invention can also be equipped with at least four tools, which can also be switched freely. Compared with the conventional spring manufacturing machine, the usability of the spring manufacturing machine of the present invention has been significantly improved.
