[0002] In modern industrial production, stamping is widely used for processing various sheet metal parts due to its advantages such as high efficiency and high precision. However, among the many stamping processing requirements, traditional processing methods have many shortcomings for some parts that require side cuts.

[0003] When side-cutting workpieces after punching, operators typically need to manually remove the stamped workpiece from the stamping die and place it on a designated positioning device for repositioning before subsequent processing. This process not only consumes a lot of manpower, but manual operation is also prone to inaccurate positioning, leading to inconsistent product quality. Furthermore, the additional removal and repositioning steps increase the complexity of the operation, extend the production cycle, and reduce overall production efficiency.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the issue that when side-cutting workpieces after punching, operators typically need to manually remove the stamped workpiece from the stamping die and place it on a designated positioning device for repositioning before subsequent processing, this process is not only labor-intensive but also prone to inaccurate positioning, leading to inconsistent product quality. Furthermore, the additional removal and repositioning steps increase the complexity of the operation, extend the production cycle, and reduce overall production efficiency. The basic concept of the technical solution adopted in this utility model is as follows:

[0006] A continuous side-cutting stamping die includes a die base and a stamping plate that slides vertically on its surface.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0025] like Figures 1 to 4 As shown, a continuous side-cutting stamping die includes a die base 1 and a stamping plate 7 that slides vertically on its surface.

[0026] The mold base 1 has a side wall with a barrier 2 installed, and a top plate 11 is movably inserted on the barrier 2. A guide block 12 is installed on the top plate 11, and a slope 13 is opened at the bottom of the guide block 12.

[0027] The side wall of the stamping plate 7 is equipped with a lifting plate 9 and an L-shaped frame 15 for positioning the stamped workpiece. The lifting plate 9 slides vertically with the stamping plate 7 to lift the stamped workpiece upward. The L-shaped frame 15 is equipped with a sliding rod 14 corresponding to the side wall of the guide block 12, and the L-shaped frame 15 slides vertically with the stamping plate 7 to press the guide block 12 and drive the top plate 11 to move horizontally. Through the linkage design of the lifting plate and the top plate, during the resetting process after the workpiece is stamped, the lifting plate lifts the workpiece upward while the top plate moves towards the center to form a limit, realizing the direct clamping of the workpiece. There is no need for additional removal and repositioning steps, which greatly simplifies the operation process, reduces manual intervention, and improves production efficiency.

[0028] A robotic arm 3 is installed on the side wall of the mold base 1, and a side-cutting component 4 is installed on the side wall of the robotic arm 3. The robotic arm 3 can drive the side-cutting component 4 to side-cut the workpiece. The robotic arm 3 and the side-cutting component 4 are existing technologies and will not be described in detail here.

[0029] like Figures 1 to 4 As shown in the specific embodiment, a frame 5 is installed on the side wall of the mold base 1, and a hydraulic push rod 6 is installed on the frame 5. The output end of the hydraulic push rod 6 is connected to the stamping plate 7. The hydraulic push rod 6 has strong power and precise control, which can provide a stable and adjustable driving force for the lifting and lowering of the stamping plate 7, ensuring stable pressure during the stamping process, thereby ensuring the forming accuracy of the stamped workpiece. At the same time, its automated driving method reduces manual intervention and improves production efficiency.

[0030] like Figures 1 to 4As shown, the mold base 1 further includes a pair of through slots 10, which are vertically aligned with the lifting plate 9. A synchronization frame 8 is mounted on the lifting plate 9 and is connected to the side wall of the stamping plate 7. The through slots 10 provide a precise guide path for the up-and-down sliding of the lifting plate 9. Together with the synchronization frame 8, the lifting plate 9 can always maintain synchronous movement with the stamping plate 7, ensuring stable operation when placing and lifting workpieces. This avoids positioning deviations caused by workpiece shaking, thereby improving the workpiece processing pass rate and reducing scrap.

[0031] like Figures 1 to 4 As shown, a sliding plate 16 is installed at the bottom of the top plate 11. A limiting rod 17 is movably connected through the sliding plate 16. The end of the limiting rod 17 is connected to the side wall of the enclosure 2. A limiting spring 19 is sleeved on the limiting rod 17. One end of the limiting spring 19 is engaged with the side wall of the enclosure 2, and the other end is engaged with the sliding plate 16. The elastic limiting structure composed of the limiting spring 19 and the limiting rod 17 not only ensures that the top plate 11 can move flexibly when subjected to force, but also provides a stable restoring force when the top plate 11 returns to its original position, ensuring that the top plate 11 can accurately return to its initial position each time, thus guaranteeing the repeatability and stability of the mold operation.

[0032] like Figures 1 to 4 As shown, a limiting plate 18 is installed at the end of the limiting rod 17, and the diameter of the limiting plate 18 is larger than the diameter of the limiting rod 17. The limiting plate 18 plays a dual role: on the one hand, it limits the movement range of the sliding plate 16, preventing the sliding plate 16 from detaching from the limiting rod 17 during movement, avoiding damage to the mold structure, and improving the reliability and service life of the mold; on the other hand, during the reset process of the top plate 11, the limiting plate 18 can make the sliding plate 16 stop precisely at the predetermined position, further ensuring the accuracy of the reset of the top plate 11 and maintaining the overall stability of the mold operation.

[0033] The implementation principle of a continuous side-cutting stamping die is as follows:

[0034] Place the stamped workpiece above the lifting plate 9, activate the hydraulic push rod 6, and its output end pushes the stamping plate 7 to slide vertically downward on the surface of the mold base 1. The lifting plate 9, which is connected to the side wall of the stamping plate 7, moves down synchronously and descends along the through groove 10 on the mold base 1 until the workpiece is placed stably on the surface of the mold base 1. At this time, the lifting plate 9 falls completely into the through groove 10.

[0035] The hydraulic push rod 6 continues to drive the stamping plate 7 to move downward, and the stamping plate 7 and the fixed mold base 1 perform stamping processing on the workpiece.

[0036] After stamping, the hydraulic push rod 6 drives the stamping plate 7 to move vertically upwards and reset. As the stamping plate 7 rises, the lifting plate 9 connected to the stamping plate 7 also rises, lifting from the through slot 10 and carrying the workpiece upwards. Simultaneously, the sliding rod 14 mounted on the L-shaped frame 15 on the side wall of the stamping plate 7 also moves upwards. When the sliding rod 14 contacts the inclined surface 13 of the guide block 12, it slides along the inclined surface and presses against the guide block 12, causing the top plate 11 to begin moving horizontally towards the center. During the movement of the top plate 11 towards the center, the limiting spring 19 is compressed, facilitating subsequent reset and assisting the top plate 11 in a smooth return movement. The limiting plate 18 restricts the movement range of the sliding plate 16, preventing it from disengaging from the limiting rod 17. The movement of the top plate 11 towards the center limits the upward movement path of the workpiece, and together with the lifting plate 9, clamps and locks the workpiece in place.

[0037] At this time, the robotic arm 3 drives the side-cutting assembly 4 to perform precise side-cutting on the fixed workpiece. When the side-cutting is completed, the hydraulic push rod 6 continues to drive the stamping plate 7 to rise to the initial position, the lifting plate 9 lifts the workpiece to a higher position, the top plate 11 is fully reset under the action of the limit spring 19, the slide rod 14 also disengages from the guide block 12, and the entire mold returns to the initial state, waiting for the next workpiece to be placed, starting a new round of continuous side-cutting stamping process.
