DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The purpose, construction, features, functions and advantages of the present invention can be appreciated and understood more thoroughly through the following detailed descriptions with reference to the attached drawings.
Refer to FIGS. 1 to 3 respectively for a front schematic diagram of a wire forming device according to an embodiment of the present invention; a back schematic diagram of a wire forming device according to an embodiment of the present invention; and a schematic diagram of a wire forming device in various steps of operation according to an embodiment of the present invention.
As shown in FIGS. 1 to 3, the present invention provides a wire forming device, comprising: a base seat 10 and four wire forming units 20.
The base seat 10 is provided with a wire output port 11 at its center, used to output the wire.
The four wire forming units 20 are disposed respectively on four corners of the base seat 10, and each having a movable plate 21. Each movable plate 21 is provided with a lower plate 211, that is able to move to left and right on the base seat 20; and an upper plate 212, that is disposed on a top surface of the lower plate 211, and is able to move upward and downward on the top surface of the lower plate 211. A plurality of tool seats 22 are located in parallel and disposed at a front end of the upper plate 212, while an up-down driver 23 is disposed at a rear end of the upper plate 212, so that up-down driver 23 drives the upper plate 212 to move upward and downward on the lower plate 211. A left-right driver 24 is disposed on a back side of the base seat 10 and on a back side of each lower plate 211, so that the left-right driver 24 drives the upper plate 212 and the lower plate 211 to move to left and right on the base seat 10 at the same time.
In operation, through driving by the up-down driver 23 and the left-right driver 24, the upper plate 212 and the lower plate 211 are driven to move separately up and down, left and right in 2 dimensions, hereby bringing a forming tool of the tool seats 22 to perform 2-dimensional processing on the wire in the wire output port 11. Therefore, the present invention is capable of simplifying the forming tool's adjustment, reducing the forming tool's stroke distance, while achieving fast feed and retraction of setup tools independently.
In the following, refer again to FIGS. 1,2, and 3. As shown in FIGS. 1,2,3, four movable plates 21 are disposed respectively on four corners of the base seat 10, to form angles of 45 degrees, 135 degrees, 225 degrees, and 315 degrees respectively with the base seat 10. For the conventional wire forming machine, movable plates 21 are disposed respectively 0 degree, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, and 315 degrees relative to the base seats 10. However, through long time observation of the Applicant, it is found that, when the movable plates 21 is located 0 degree to 180 degrees relative to the base seat 10, the force of moving downward the driving device is required to provide is minimal, while the force of moving upward the driving device is required to provide is greater. When the movable plates 21 is located 90 degrees to 270 degrees relative to the base seat 10, the force of moving forward and backward the driving device is required to provide is minimal.
Therefore, when the movable plates 21 is located 45 degrees, 135 degrees, 225 degrees, and 315 degrees relative to the base seat 10, the up-down driver 23 and the left-right driver 24 may provide the most even driving force, for the left-right and up-down movements.
A servo motor is each provided on the up-down driver 23 and the left-right driver 24, to drive the movable plates 21.
The setup tool of the tool seat 22 is a forming tool used to make the spring. The forming tool can be set up to move in two dimensions. The strength of the spring can be controlled. For the spring of stronger strength, the density of the spring is made higher, while for the spring of less strength, the density of the spring is made lower.
The upper plate 212 is disposed on a sliding rail 2121 on a top surface of the lower plate 211, such that it is able to move upward and downward on the top surface of the lower plate 211.
The lower plate 211 is disposed on a sliding rail 2111 in the base seat 10, such that it is able to move to the left and to the right on the base seat 10.
Refer to FIGS. 4A,4B,4C,4D,4E,4F respectively for schematic diagrams of a wire forming device in various steps of operation according to an embodiment of the present invention. As shown in FIGS. 4A to 4F, through using the up-down driver 23 and the left-right driver 24, the upper plate 212 and the lower plate 211 can be set up to move upward, downward, left, and right in two dimensions, such that two opposite upper plate 212 and the lower plate 211 can be set up to move upward, downward, left, and right in two dimensions, thus the forming tool of different tool seats 22 may perform processing to produce springs (as shown in FIGS. 4A,4B,4C). Alternatively, two adjacent upper plate 212 and the lower plate 211 can be made to move upward, downward, left, and right in two dimensions, as such the forming tool of different tool seats 22 may perform processing to produce springs (as shown in FIG. 4D). In addition, three sets of upper plates 212 and the lower plates 211 can be set up to move upward, downward, left, and right in two dimensions, thus the forming tool of different tool seats 22 may perform processing to produce springs (as shown in FIG. 4E). Further, four sets of upper plates 212 and the lower plates 211 can be set up to move upward, downward, left, and right in two dimensions, as such the forming tool of different tool seats 22 may perform processing to produce springs (as shown in FIG. 4F).
The above detailed description of the preferred embodiment is intended to describe more clearly the characteristics and spirit of the present invention. However, the preferred embodiments disclosed above are not intended to be any restrictions to the scope of the present invention.
