Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, specifically relating to a die for continuous rolling forming. Background Technology

[0002] For parts like printer shafts, current technology generally uses rollers for production. However, this roller method has drawbacks compared to stamping, including higher processing costs and lower production efficiency. Stamping is a pressure processing method that uses a die mounted on a press at room temperature to apply pressure to material, causing it to separate or plastically deform, thereby obtaining the desired part. If the stamping dies used in stamping can be designed as progressive dies, production efficiency can be significantly improved, and processing costs can be reduced. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a mold for continuous rolling and forming. By setting up components such as drilling, forming, rolling, shaping, and finished product cutting in a single mold, continuous feeding and continuous batch processing can be achieved, thereby improving production efficiency and reducing processing costs.

The burrs on both sides of the workpiece segment are removed; the first forming component, the second forming component, and the third forming component sequentially extrude the workpiece segment upwards to form an arc surface with increasing curvature; the upper bending component bends the arc-shaped workpiece segment upwards by 90 degrees, with the arc opening of the workpiece segment facing the discharge direction, and the workpiece segments are connected by connecting pieces at the edge grooves; the first rounding component initially presses the arc-shaped workpiece segment into a circular workpiece; the second rounding component presses the workpiece into a circle again; the lower bending component bends the entire workpiece downwards, and the connecting pieces between the workpiece segments return to the horizontal position; the cutting component cuts off the connecting pieces between the workpiece segments, and the workpiece is cut off and discharged.

[0006] Furthermore, the connection point between the workpiece segment and the connecting piece at the edge groove is located at the middle of both ends of the workpiece segment.

[0007] Furthermore, one end of the lower mold discharge is provided with an inclined surface that guides the workpiece downwards to the outside of the mold.

[0008] Furthermore, the first rounding component and the second rounding component each include two punches in the vertical position direction.

[0009] Furthermore, at least two upper bending components are provided, and the bending angles are progressively increased.

Detailed Implementation

[0015] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0016] like Figures 1-3As shown, a mold for continuous rolling forming includes an upper mold 1 and a lower mold 2. The upper mold 1 and lower mold 2 are sequentially provided with a punching hole assembly 3, a grooving assembly 4, a deburring assembly 5, a first forming assembly 6, a second forming assembly 7, a third forming assembly 8, an upper bending assembly 9, a first rounding assembly 10, a second rounding assembly 11, a lower bending assembly 12, and a cutting assembly 13 along the feeding direction of the material plate. The punching hole assembly 3 punches equidistantly distributed edge holes on both sides of the material plate along the feeding direction. The grooving assembly 4 cuts strip-shaped grooves perpendicular to the feeding direction and edge grooves at both ends of the strip-shaped grooves on the material plate. The sheet material between adjacent strip-shaped grooves forms a workpiece segment to be formed into a workpiece 14. The deburring assembly 5... The burrs on both sides of the workpiece segment are removed; the first forming component 6, the second forming component 7, and the third forming component 8 sequentially extrude the workpiece segment upwards to form an arc surface with increasing curvature; the upper bending component 9 bends the arc-shaped workpiece segment upwards by 90 degrees, with the arc opening of the workpiece segment facing the discharge direction, and the workpiece segments are connected by connecting pieces at the edge groove; the first rounding component 10 initially presses the arc-shaped workpiece segment into a circular workpiece 14; the second rounding component 11 presses the workpiece 14 into a circle again; the lower bending component 12 bends the workpiece 14 downwards as a whole, and the connecting pieces between the workpiece segments return to the horizontal position; the cutting component 13 cuts the connecting pieces between the workpiece segments, and the workpiece 14 is cut off and discharged.

[0017] The connection point between the workpiece segment and the connecting piece at the side groove is located in the middle of both ends of the workpiece segment.

[0018] The lower mold 2 has a sloping surface at one end for discharging the workpiece 14 downwards to the outside of the mold.

[0019] The first rounding component 10 and the second rounding component 11 each include two punches in the vertical position direction.

[0020] Multiple upper bending components 9 are provided, and the bending angle is gradually increased.

[0021] This utility model discloses a mold for continuous rolling and forming, such as for continuous processing of printer shafts. Within a single mold, between the upper mold 1 and the lower mold 2, along the processing feed direction, are sequentially arranged a punching hole assembly 3, a grooving assembly 4, a deburring assembly 5, a first forming assembly 6, a second forming assembly 7, a third forming assembly 8, an upper bending assembly 9, a first rounding assembly 10, a second rounding assembly 11, a lower bending assembly 12, and a cutting assembly 13. Figure 2 and Figure 3At station A, the punching hole assembly 3 punches out circular edge holes. At station B, the grooving assembly 4 cuts out strip grooves to form workpiece segments (one workpiece segment, after being rolled into a circle, forms a printer shaft). At station C, the grooving assembly 4 cuts out edge grooves. At station D, the deburring assembly 5 removes burrs from the strip grooves. At station E, the first forming assembly 6 bends the workpiece segment upwards. At station F, the second forming assembly 7 increases the curvature of the workpiece segment and bends it upwards again. At stations G, H, and I, the upper bending assembly 9 gradually bends the workpiece segment upwards, ultimately bending it 90 degrees, resulting in a curved surface processed at station F. The rotation direction is such that the arc-shaped opening faces the discharge direction. Changing the orientation of the arc-shaped opening facilitates the subsequent rolling operation. Because the upper die 1 and the lower die 2 move relative to each other, station J uses the first rounding component 10 to initially roll the workpiece segment. Station K uses the second rounding component 11 to roll the workpiece segment again. Stations L, M, and N use the lower bending component 12 to gradually restore the bending completed by the upper bending component 9 before the rolling operation to the original bending state. Station O uses the shaping component to shape the workpiece, facilitating accurate cutting and unloading later. Station P uses the cutting component 13 to cut and separate the workpiece 14 from the material plate. Station Q completes the unloading of workpiece 14. The entire processing process is completed automatically and continuously, with high processing efficiency.

[0022] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
