Description

Technical Field

[0001] This utility model relates to the field of spring manufacturing, and more specifically, to a forming tooling for achieving efficient forming of Z-shaped springs. Background Technology

[0002] Z-shaped springs are generally Z-shaped springs, and are typically manufactured using CNC spring machines. During manufacturing, forming dies are mounted on multiple sliding seats on the spring machine. The machine, according to pre-set parameters, controls the sliding seats to move sequentially, causing the forming dies to move in a sequential manner, thus shaping the wire into a Z-shape. While existing CNC spring machines are highly versatile, their center-discharge method means that the forming dies need to perform two compression actions on the Z-shaped spring to achieve the Z-bend, resulting in lower overall processing efficiency and higher costs. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a highly efficient forming tooling that can form a Z-shaped bend with only one extrusion action.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A forming fixture for efficient Z-shaped spring forming includes a spring machine with a side discharge port and multiple sliding seats. A cutter is provided on the sliding seat above the discharge port on the spring machine, and the cutter is close to the discharge port. A Z-shaped mold is provided on the sliding seat below the discharge port. The top of the Z-shaped mold has a Z-shaped forming surface composed of three forming surfaces, and the upper forming surface of the Z-shaped forming surface is close to the discharge port. An extrusion head is provided on the sliding seat diagonally above the discharge port. The extrusion head points to the concave corner of the Z-shaped forming surface and is used to extrude the wire extending from the discharge port to conform to the Z-shaped forming surface.

[0006] In a further improvement, the angle at the concave corner of the Z-shaped forming surface is smaller than the bending angle required by the Z-shaped spring.

[0007] As a further improvement, the upper forming surface of the Z-shaped forming surface is provided with an upper groove adapted to the wire.

[0008] As a further improvement, the lower forming surface of the Z-shaped forming surface is provided with a lower groove adapted to the wire.

[0009] In a further improvement, the lower groove gradually deepens from the concave corner of the Z-shaped forming surface outwards.

[0010] As a further improvement, the edges of the top ends of both the upper and lower grooves are provided with transition rounded corners.

[0011] As a further improvement, the concave corner of the Z-shaped forming surface is provided with a transition rounded corner.

[0012] In a further improvement, the front end of the extrusion head is provided with an extrusion flat head, and the extrusion flat head is provided with a notch adapted to the wire.

[0013] As a further improvement, the edges of the notch are provided with transition rounded corners.

[0014] In summary, the beneficial effects of this utility model are as follows: This utility model adopts a spring machine with a side discharge port, and a cutter, a Z-shaped mold, and an extrusion head are respectively set on the spring machine. During operation, the wire extends from the discharge port to the top of the Z-shaped mold. The lower sliding seat pushes the Z-shaped mold to move close to the wire, and the upper sliding seat pushes the extrusion head to extrude the wire, making the wire conform to the Z-shaped forming surface. Subsequently, the upper sliding seat pushes the cutter to cut the wire from near the discharge port, completing the processing of the Z-shaped spring. This utility model uses a Z-shaped mold and an extrusion head, so that the wire can form a Z-shaped structure in one extrusion action, which has higher processing efficiency and helps to reduce costs.

[0026] Reference Figures 1 to 4 A forming fixture for efficient forming of Z-shaped springs includes a CNC spring machine 1, wherein the spring machine 1 has a side discharge port 11 on one side and multiple sliding seats 12.

[0027] The spring machine 1 has a sliding seat 12 located above the discharge port 11 with a cutter 2. The cutter 2 is close to the discharge port 11. The sliding seat 12 can drive the cutter 2 to move up and down to cut the wire from near the discharge port 11.

[0028] The sliding seat 12 of the spring machine 1 located below the discharge port 11 is provided with a Z-shaped mold 3. The top of the Z-shaped mold 3 is provided with a Z-shaped forming surface composed of three forming surfaces, and the upper forming surface of the Z-shaped forming surface is close to the discharge port 11.

[0029] The spring machine 1 has a sliding seat 12 located obliquely above the discharge port 11, which is equipped with an extrusion head 4. The extrusion head 4 points to the concave corner 31 of the Z-shaped forming surface. The sliding seat 12 is used to push the extrusion head 4 to move back and forth. When moving forward, it can extrude the wire extending from the discharge port 11 to make it conform to the Z-shaped forming surface.

[0030] like Figure 5The Z-shaped spring shown is formed by bending a wire to create a roughly Z-shaped structure. When processing the Z-shaped spring using the above-mentioned forming fixture, the wire extends from the discharge port 11 to the top of the Z-shaped mold 3. The lower sliding seat 12 pushes the Z-shaped mold 3 upward to close to the wire. The upper sliding seat 12 pushes the extrusion head 4 forward to extrude the wire, making the wire fit the Z-shaped forming surface and forming the shape. Then, the upper sliding seat 12 pushes the cutter 2 to move and cut the wire near the discharge port 11.

[0031] In one embodiment, such as Figure 3 As shown, the angle at the concave corner 31 of the Z-shaped forming surface is smaller than the bending angle required by the Z-shaped spring. When the extrusion head 4 extrudes the wire to conform to the Z-shaped forming surface, it can achieve a larger bending angle. After the extrusion head 4 is released, the wire recovers a certain amount due to its own elasticity, allowing it to better achieve the required bending angle.

[0032] In one embodiment, such as Figure 3 As shown, the upper forming surface of the Z-shaped forming surface is provided with an upper groove 32 adapted to the wire. The lower forming surface of the Z-shaped forming surface is provided with a lower groove 33 adapted to the wire. The upper groove 32 and the lower groove 33 can limit the wire when the extrusion head 4 extrudes the wire, ensuring better forming quality. Furthermore, the lower groove 33 gradually deepens from the concave corner 31 of the Z-shaped forming surface outwards, providing a larger forming space for the wire to gradually move outwards during forming, preventing the edge of the lower forming surface of the Z-shaped forming surface from scratching the wire.

[0033] In one embodiment, such as Figure 3 As shown, the top edges of both the upper groove 32 and the lower groove 33 are provided with rounded corners. These rounded corners reduce the sharpness of the edges and prevent scratching the wire. Furthermore, the corner 31 of the concave Z-shaped forming surface is provided with rounded corners. The rounded corners at the corners 31 reduce bending and stress at the corners, ensuring the mold life.

[0034] In one embodiment, such as Figure 4 As shown, the front end of the extrusion head 4 is provided with an extrusion flat head, and the extrusion flat head is provided with a notch 41 adapted to the wire. The edges of the notch 41 are all provided with transition rounded corners. The notch 41 can limit the wire during extrusion, prevent it from shifting, and improve processing accuracy. The transition rounded corners at the edges of the notch 41 can also prevent scratching the wire and ensure the surface quality of the Z-shaped spring after forming.

[0035] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
