Description

Technical Field

[0001] The present invention relates to the technical field of numerical control spring forming, and in particular to a 3D forming structure of a numerical control spring forming machine. Background Art

[0002] At present, the forming of springs often requires the use of CNC spring forming machines for production, but the existing CNC spring forming machines have the following problems: First, when it comes to some complex special-shaped springs, due to the large number of spring corners and complex shapes, when using the existing CNC spring forming machines to make springs, the number of processing components that can be installed on the main panel of the machine is limited, resulting in some special shapes being difficult to process; Second, Figure 7 , Figure 8 , Fig. 9 When it comes to some special-shaped springs with simple shapes and long lengths, in order to ensure that the springs are not interfered with by the main panel of the machine or the components on the main panel of the machine, the wire outlet shaft core needs to be lengthened to be greater than the total length of the spring. Since the wire outlet shaft core is lengthened, it is also necessary to add a spacer block between the slide and the angle tool, thereby increasing the production cost and reducing the production stability; thirdly, when it comes to some springs that need to be stamped, since the stamping device cannot be installed on the machine, additional stamping processing steps need to be performed on other machines, resulting in the problem that some springs need to be processed secondary, thereby reducing production efficiency. Summary of the invention

[0003] The object of the present invention is to provide a 3D forming structure of a CNC spring forming machine to solve the technical problem that the existing CNC spring forming machine cannot process special shapes when manufacturing complex special-shaped springs.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present invention provides a 3D forming structure of a CNC spring forming machine, including a machine main panel installed in a vertical direction, a wire outlet shaft core is provided on the front of the machine main panel, and the wire outlet shaft core conveys the spring to be processed outward, and a plurality of second processing components are provided on the front of the machine main panel, and the second processing components perform processing on the spring to be processed in the up, down, left and right directions; a horizontally installed support platform is provided below the wire outlet shaft core, and a first processing component is provided on the top surface of the support platform, and the first processing component performs processing on the spring to be processed in the front and back directions.

[0005] As a preferred implementation manner, the first processing assembly includes a first slide seat, and the first slide seat is installed on the supporting platform.

[0006] Furthermore, an arc-shaped sliding structure is provided on the top surface of the support platform, and the direction of the arc-shaped sliding structure is toward the front of the main panel of the machine. The first slide seat is slidably matched with the arc-shaped sliding structure so that the first slide seat can be adjusted arbitrarily within a range of 180 degrees along the arc-shaped sliding structure.

[0007] Furthermore, a first slider is provided on the top surface of the first slide seat, and the first slide seat and the first slider are slidably matched. A first driving device is also provided on the first slide seat, and the first driving device drives the first slider to move forward and backward through a first driving rod. A first tool device is provided on the first slider.

[0008] Furthermore, the first tool device is a curler having a bending groove thereon; the spring to be processed is provided with a first bending angle and a second bending angle, and when the spring to be processed is inserted into the bending groove, the first bending angle and the second bending angle are bent and formed by the rotational movement of the curler.

[0009] As another preferred implementation manner, the first processing component is a stamping die, and the spring to be processed is stamped by the stamping die.

[0010] Furthermore, the support platform is in the shape of a semicircular panel, and the top surface of the support platform forms a 90-degree angle with the front surface of the main panel of the machine.

[0011] Furthermore, the rear end of the support platform is fixed to the front side of the main panel of the machine through a fixing module, and the front end of the support platform is supported upward by the top end of the support rod.

[0012] Furthermore, the 3D forming structure of the CNC spring forming machine also includes a machine platform, the main panel of the machine platform is fixed on the machine platform, and the bottom end of the support rod is connected to the machine platform.

[0013] Furthermore, the main panel of the machine is in the shape of a circular plate, and a circular sliding groove is provided on the front side of the main panel of the machine, and the second processing component can be adjusted arbitrarily within a range of 360 degrees along the circular sliding groove.

[0014] In summary, the technical scheme of the present invention has the following beneficial effects: the structural design of the present invention is reasonable. By installing a support platform in the horizontal direction and providing a first processing assembly on the top surface of the support platform, the processing of the spring to be processed in the front and rear directions is increased, and then the processing of the special-shaped spring in multiple directions is realized in cooperation with the second processing assembly to complete the processing of special shapes, thereby solving the technical problem that the existing CNC spring forming machine cannot process special shapes when manufacturing complex special-shaped springs. By providing an arc-shaped sliding structure on the top surface of the support platform, the first slide seat can be adjusted arbitrarily within a range of 180 degrees along the arc-shaped sliding structure, thereby improving the processing angle adjustment ability of the first processing assembly in the horizontal direction, thereby further improving the ability to process the special shape of the special-shaped spring. By installing a curler on the top surface of the support platform, the curler performs the bending and forming of the special-shaped spring at the first bending angle and the second bending angle, thereby avoiding the lengthening of the outlet shaft core and the addition of the pad block, thereby reducing the production cost and improving the production stability. By installing a stamping die on the top surface of the supporting platform, the stamping die stamps the first bending angle and the second bending angle of the special-shaped spring, thereby adding the function of directly stamping the spring to be processed, and solving the technical problem that secondary processing is required due to the inability to install a stamping device on the existing machine.

The number of the first processing components 4 can be selected according to actual needs. Preferably, the number of the first processing components 4 is one to five, and other numbers are also acceptable, so as to complete the processing of special shapes, thereby solving the technical problem that the existing CNC spring forming machines are unable to process special shapes when manufacturing complex special-shaped springs.

[0032] As a preferred implementation, see Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11Preferably, the number of the first processing assembly 4 is one, and the first processing assembly 4 includes a first slide 401, which is installed on the support platform 3.

The first slide 401 and the arc-shaped sliding structure 303 are slidably matched, so that the first slide 401 can be arbitrarily adjusted within a range of 180 degrees along the arc-shaped sliding structure 303.
