Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a side-sliding side-forming die with a suspended punch. Background Technology

[0002] After being bent and formed in a stamping die, stamped parts will have varying degrees of springback, requiring necessary shaping processes.

[0003] Shaping generally adopts the side shaping method. The traditional side shaping mold structure includes an upper mold pressure block, an upper mold inclined insertion block, a lower module and a side slider. The workpiece to be shaped is placed on the lower module and pressed by the upper mold pressure block. The side slider is located on the side of the lower module and is driven by the upper mold inclined insertion block to act on the part of the workpiece that needs to be shaped. In addition, the side slider needs to be guided by a guide block to ensure accurate displacement and reset by a spring. The above-mentioned lower side punch shaping mechanism requires a large stroke and cannot realize complex surface shaping and product stripping in a mold with limited space.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

Example

[0038] Please see Figure 1-5 This application discloses a side-sliding side-forming die with a suspended punch, comprising an upper die 10 and a lower die 20.

[0039] The upper mold 10 includes an upper support plate 11, an upper mold base 12, and a stripper plate 13 arranged sequentially from top to bottom. A plurality of upper pads 14 are evenly distributed between the upper support plate 11 and the upper mold base 12. Two upper clamping plates 15 are arranged opposite each other on both sides of the upper mold base 12. Four upper mold shaping blocks 16 are movably installed on the two upper clamping plates 15. The four upper mold shaping blocks 16 are arranged opposite each other in pairs and move towards each other in pairs.

[0040] The lower mold 20 includes a lower template 21, a lower mold base 22, and a lower support plate 23 arranged sequentially from top to bottom. Several lower pads 24 are evenly distributed between the lower mold base 22 and the lower support plate 23. Four lower mold blocks 25 are provided on both sides of the lower template 21. The lower mold blocks 25 correspond to and cooperate with the upper mold shaping blocks 16. In this embodiment, the lower template is provided with side walls that are adapted to the complex shape of the material sheet. Through the above structural design, the upper mold shaping block and the lower mold blocks of the hanging punch side sliding type cooperate to realize the side shaping operation. Not only is the stroke small, but it can also realize the shaping of complex surfaces and product unloading in the mold with limited space.

[0041] Before the mold is closed, the sheet to be shaped is placed on the lower mold plate. The upper mold moves downward, and the stripper plate contacts the sheet first and then presses it down. The upper mold continues to move downward, and the upper mold shaping punch moves towards the lower mold plate, i.e., the inside of the mold, under the guidance and drive of the corresponding lower mold block. The four upper mold shaping blocks move towards each other in pairs, thereby completing the lateral shaping of the sheet. This method can effectively achieve precise forming of complex product surfaces, while ensuring smooth demolding and avoiding space waste and structural complexity caused by excessive stroke of the upper mold shaping blocks.

[0042] Specifically, four first nitrogen springs 111 are installed on the upper support plate 11. The four first nitrogen springs 111 pass through the upper die base 12 and are connected to the stripper plate 13. By setting these first nitrogen springs, a stable pressing force is provided during the stamping process to ensure that the sheet is firmly pressed against the surface of the lower die during the stamping process, preventing the sheet from sliding, wrinkling or deforming during stamping, thereby ensuring the forming quality of the parts. After the stamping is completed, the upper die moves upward, and these first nitrogen springs continue to provide downward elastic force to push the stripper plate to push the sheet out smoothly, realizing automatic stripping and preventing the sheet from sticking or jamming the die.

[0043] Specifically, the upper die base 12 is provided with three sliding grooves (not shown in the figure) on the side facing the upper clamping plate 15. The upper clamping plate 15 reciprocates linearly along the sliding grooves. Three sliders 151 are provided on the upper clamping plate 15. A second nitrogen spring 152 is provided between the slider 151 and the groove wall of the sliding groove. A positioning block 153 is provided in each sliding groove. One end of the second nitrogen spring 152 relative to the slider 151 is connected to the positioning block 153. When the upper die moves downward, the upper die forming punch moves towards the lower die plate under the guidance and drive of the corresponding lower die block. The second nitrogen spring is compressed. After the side forming is completed, the upper die forming block is reset under the action of the second nitrogen spring. The upper die continues to move upward, and the upper die forming block is separated from the material sheet, completing the entire stripping process.

[0044] Specifically, each end of the lower template 21 is provided with two slide blocks 211, and the four slide blocks 211 cooperate with the lower template 21. The upper mold base 12 is provided with four inclined slide blocks 121, and the inclined slide blocks 121 are arranged one-to-one with the slide blocks 211. Each of these slide blocks is provided with an inclined slide groove, and the inclined slide blocks are slidably installed in the inclined slide groove of the corresponding slide block. When the mold is closed, the upper mold drives the inclined slide blocks to move in the inclined slide groove. When forming, the inclined slide blocks cooperate with the upper mold forming block to complete the forming of the end of the material sheet, so as to meet the forming requirements of different material sheets.

[0045] Specifically, the two slide blocks 211 in the same direction are both mounted on a slide block mounting plate 212, and the slide block mounting plate 212 is mounted on the lower template 21.

[0046] Specifically, a wear-resistant plate 251 is provided on the mating surface of the lower mold support block 25 and the upper mold shaping block 16. In this embodiment, the lower mold support block 25 has a lower inclined surface, and the upper mold shaping block has an upper inclined surface. The wear-resistant plate is fixed on the lower inclined surface to avoid direct contact between the upper mold shaping block and the lower mold support block, thereby significantly reducing wear.

[0047] Specifically, the lower mold base 22 is provided with four outer guide posts 221, and the upper mold base 12 is provided with four outer guide sleeves 122. The outer guide posts 221 and the outer guide sleeves 122 are matched one-to-one to guide the upper mold to descend accurately in the vertical direction, ensuring that the upper mold and the lower mold are precisely aligned and preventing misalignment.

[0048] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, short stroke, and small space occupation.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
