Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a novel interactive wedge mechanism. Background Technology

[0002] Stamping dies are specialized tools used in metal processing and are widely used in manufacturing industries such as automobile manufacturing, home appliance manufacturing, and electronic equipment manufacturing. Stamping is a process in which metal sheets are placed in a die and pressure is applied to cause the sheet to undergo plastic deformation or separation, thereby obtaining the desired shape and size.

[0003] When a negative angle exists in a localized area of ​​a workpiece, a lower movable punch needs to be designed to avoid the negative angle, ensuring smooth handling and feeding during production. This is typically achieved using an interactive wedge mechanism. Existing interactive wedge mechanisms (such as...) Figure 1 The die assembly includes a lower movable punch, a lower die core, a lower filling wedge, a lower die core, and an upper forming wedge. Its working principle is as follows: the workpiece is placed on the lower die core and the lower die core. The lower filling wedge is driven forward by a cylinder, supporting the lower movable punch to the right. The upper die moves downward, and the upper forming wedge descends along the stamping angle, ultimately completing the forming action. After forming, the upper die, carrying the upper forming wedge, retracts in the opposite direction of the side forming and completely exits the workpiece. The lower filling wedge is then pulled back to its original position by a cylinder, and the lower movable punch retracts to the left, disengaging from the negative angle range of the workpiece. After complete disengagement, the part is safely removed.

[0004] The existing interactive wedge mechanism has the following drawbacks:

[0005] 1. When the movable punch and the lower die core are in the correct position, there is a gap between them, resulting in no support on the rear side of the lower movable punch forming area. During the forming process, the forming force is large, causing the lower movable punch to deform backward, and a stepped ridge appears at the side flip position, resulting in a defective product.

[0006] 2. During the leftward movement of the lower moving punch driven by the lower filling wedge, the driving position is close to the lower part of the lower moving punch, and the force point is too close to the bottom, resulting in an unsmooth driving process.

[0007] Therefore, there is an urgent need to design a new type of interactive wedge mechanism to solve the problems existing in the interactive wedge mechanism in the above-mentioned technologies. Summary of the Invention

[0008] The purpose of this invention is to provide a novel interactive wedge mechanism with optimized structure that meets the needs of wedges with insufficient space and can achieve both guiding and forced reset functions.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A novel interactive wedge mechanism includes a lower movable punch, a lower die core (part one), a lower filling wedge, a lower die core (part two), and an upper shaping wedge, and further includes:

[0011] A filling pad is installed in the gap between the lower movable punch and the lower die core.

[0012] Furthermore, the filling pad has an L-shaped structure;

[0013] The bottom edge of the filling pad is fixedly connected to the lower filling wedge.

[0014] Furthermore, the cylinder drives the lower filling wedge to move towards the lower movable punch until the filling pad is positioned between the lower movable punch and the lower die core.

[0015] Furthermore, the filling pad has a steel plate and a guide plate;

[0016] The guide plate is fixedly connected to one side of the steel plate by screws;

[0017] The outer sides of the guide plate and the steel plate are respectively attached to the two parts of the lower mold core and the lower movable punch.

[0018] Furthermore, a pad is added between the steel plate and the guide plate to adjust the tightness of the filling pad installation.

[0019] In the above technical solution, the novel interactive wedge mechanism of this utility model has the following beneficial effects:

[0020] This utility model provides a novel interactive wedge mechanism. Compared with the traditional interactive wedge mechanism, a filling pad is added to the rear side of the lower movable punch for support, which avoids the deformation of the casting during the forming process caused by the opening on the rear side of the lower movable punch, reduces the fitter's grinding and fitting time, and ensures the quality of the manufactured parts.

[0033] See Figures 1-6 As shown;

[0034] A novel interactive wedge mechanism includes a lower movable punch 1, a lower die core part 2, a lower filling wedge 3, a lower die core part 2 4, and an upper shaping wedge 5, and further includes:

[0035] The filling pad 6 is installed in the gap between the lower movable punch 1 and the lower die core 4.

[0036] The filling pad 6 has an L-shaped structure;

[0037] The bottom edge of the filling pad 6 is fixedly connected to the lower filling wedge 3.

[0038] The cylinder drives the lower filling wedge 3 to move downward towards the moving punch 1 until the filling pad 6 is placed between the lower moving punch 1 and the lower die core 4.

[0039] The filling pad 6 has a steel plate 61 and a guide plate 62;

[0040] The guide plate 62 is fixedly connected to one side of the steel plate 61 by screws;

[0041] The outer sides of the guide plate 62 and the steel plate 61 are respectively attached to the lower mold core 4 and the lower movable punch 1.

[0042] A pad is added between the steel plate 61 and the guide plate 62 to adjust the tightness of the filling pad 6 during installation.

[0043] When using this mechanism, the workpiece is first placed on the lower mold core part 2 4 and the lower mold core part 1 2. During the mold closing process, the lower filling wedge 3 is driven by the cylinder to move laterally, that is, to move towards the lower movable punch 1 so that the filling pad 6 is gradually placed between the lower movable punch 1 and the lower mold core part 2 4. At this time, the filling pad 6 supports the lower movable punch 1, the upper mold moves downward, and the upper shaping wedge 5 moves downward along the working angle to perform side shaping. After the shaping is completed, the upper mold carries the upper shaping wedge 5 and moves upward and backward along the side shaping angle. After the upper shaping wedge 5 leaves the workpiece range, the lower filling wedge 3 is pulled back to the retraction position by the cylinder, the lower movable punch 1 moves backward, and after avoiding the negative angle range of the workpiece, the part is safely taken out. During the entire shaping process, the lower movable punch 1 is supported at multiple points by the filling pad 6 on the rear side to ensure the force range. The lower movable punch 1 is not deformed by force after being supported.

[0044] The function of the newly added filling pad 6 is to support the lower movable punch 1 during the production process and prevent the lower movable punch 1 from deforming in the direction of the lower mold core 4 during the production process;

[0045] The filling pad 6 is formed by combining steel plate 61 and guide plate 62. On site, according to the gap between the lower movable punch 1 and the lower die core 4, a pad is added on the rear side of the guide plate 62 (between steel plate 61 and guide plate 62) to adjust the tightness and avoid jamming during the movement.

[0046] Compared with the traditional interactive wedge mechanism, a filling pad 6 is added to the rear side of the lower movable punch 1 for support, which avoids the deformation of the casting during the forming process caused by the open space on the rear side of the lower movable punch 1, reduces the fitter's grinding and fitting time, and ensures the quality of the manufactured parts.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
