Description

Technical Field

[0001] The invention relates to the technical field of automobile stamping side forming dies, in particular to a novel parent-child angular wedge structure. Background Art

[0002] Nowadays, the design cycle of automobile models is getting shorter and shorter. In process design, in order to save costs and improve efficiency, the number of processes is usually reduced as much as possible, which leads to very compact work content within the process. Figure 4 As shown in the figure; Under this process design, there will be interference between the various work contents during structural design, such as Figure 6 According to the conventional structure design under the process, if the left side shaping and side flanging are designed as conventional reference wedges as shown in the attached Figure 7 , it will interfere with the right side trimming and the positive flanging, and will weaken the structural strength of the punch; this makes it impossible to carry out normal design ideas.

[0003] At this time, the side shaping part is limited by space, and the reference wedge needs to be designed as a rotating wedge. Since the rotating wedge needs to extend the rotation axis, it is difficult to design the reference wedge at the local side flanging part; other methods have relatively complex structures and are not conducive to layout; for example, patent CN 215965598U discloses a side shaping mechanism for a fender, wherein the side shaping mechanism includes an upper die arranged on a device, a lower die used in conjunction with the upper die, a pressing core arranged on the upper die, a pulley insert arranged on one side of the upper die, a side flanging unit arranged on the other side of the upper die and on the lower die, a driving pulley arranged on the lower die, and a side shaping unit arranged on the upper die and the lower die; this solution has a complex structure. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a novel parent-child inclined wedge structure to achieve the purpose of integrated setting and compact structure.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] The novel parent-child slanted wedge structure comprises a side shaping rotating slanted wedge structure, wherein the side shaping rotating slanted wedge structure comprises an upper die side shaping mechanism and a lower die reference slanted wedge mechanism, wherein the upper die side shaping mechanism comprises an upper die slide block and a side shaping knife block mounted on the upper die slide block, wherein the lower die reference slanted wedge mechanism comprises a lower die rotating slanted wedge base and a punch reset block mounted thereon, and further comprises a side flanging slanted wedge mechanism for side flanging of a plate, wherein the side flanging slanted wedge mechanism comprises an upper die side flanging mechanism and a lower die reference slanted wedge mechanism, wherein the lower die reference slanted wedge mechanism comprises a lower die pulley, wherein the punch reset block is integrated with the pulley, and the side flanging lower die reference slanted wedge is integrated on the side shaping rotating slanted wedge base.

[0007] Further:

[0008] The side shaping rotating wedge base is arranged on the lower mold body.

[0009] The side flanging reference inclined wedge is correspondingly arranged on one side of the side shaping rotating inclined wedge.

[0010] A side shaping reference punch is provided corresponding to the side shaping rotary wedge.

[0011] The outer end of the side flanging reference wedge is arranged corresponding to the upper die inserting knife on the upper die body.

[0012] The inner end of the side flanging reference wedge is provided with a side flanging knife block.

[0013] The inner end top of the side flanging reference wedge is provided with a profile matched with the edge of the upper pressing core.

[0014] The side shaping reference punch is arranged on the lower die body through a sliding structure.

[0015] A groove is provided on one side of the side shaping rotating wedge base, and the side flanging reference wedge is arranged in the groove.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The new mother-and-child slant wedge structure is reasonably designed. By integrating two reference slant wedges that interfere with each other and cannot be designed into a new mother-and-child slant wedge structure, it can meet the requirements of fewer structural mold processes, improve efficiency, and reduce costs; the integrated setting has a compact structure.

[0026] The specific implementation modes of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0027] like Figures 1 to 5 As shown, the new type of parent-child slant wedge structure in which the reference slant wedge is installed on the rotating slant wedge includes a side shaping rotating slant wedge structure and a side flanging slant wedge mechanism for the side flanging of the plate; the side shaping rotating slant wedge structure includes an upper die side shaping mechanism and a lower die reference slant wedge mechanism, the upper die side shaping mechanism includes an upper die slide block 10 and a side shaping knife block 11 installed on the upper die slide block, the lower die reference slant wedge mechanism includes a lower die rotating slant wedge base and a punch reset block installed thereon; the side flanging slant wedge mechanism includes an upper die side flanging mechanism and a lower die reference slant wedge mechanism, the lower die reference slant wedge mechanism includes a lower die pulley, the punch reset block and the pulley are integrated, and the side flanging lower die reference slant wedge is integrated on the side shaping rotating slant wedge base

[0028] An upper pressing core 5 and an upper die insert 9 are provided at the lower part of the upper die body; a side shaping rotating wedge base 1 is provided on the lower die body 8; a side shaping reference punch 3 is provided corresponding to the side shaping rotating wedge, and the side shaping reference punch and the fixed punch 6 cooperate to form an integral punch structure, and the side shaping of the edge of the plate has a negative angle after the side shaping is completed, which is not convenient for removal;

[0029] To this end, the side shaping reference punch 3 is arranged on the lower die body through a sliding structure. After the side shaping is completed, the side shaping reference punch is withdrawn, and the plate is easily taken out.

[0030] The side flanging reference wedge is arranged correspondingly on one side of the side shaping rotating wedge; the outer end of the side flanging reference wedge is arranged correspondingly on the upper die inserting knife on the upper die body; the integrated arrangement has a compact structure.

[0031] Furthermore, a groove is provided on one side of the side shaping rotating bevel wedge base, and the side flange reference bevel wedge is integrated in the groove, with a compact structure; rotating bevel wedge rotating axes 2 are provided on opposite sides of the side shaping rotating bevel wedge base, specifically, the rotating bevel wedge rotating axes are integrated on the outer side of the side shaping rotating bevel wedge base.

[0032] The inner end of the side flanging reference wedge is provided with a side flanging knife block 7, and the top of the inner end of the side flanging reference wedge is provided with a profile that matches the edge of the upper pressing core to improve the forming effect.

[0033] The side flanging reference wedge mechanism installed on the side shaping rotating wedge: the upper part includes the upper die body, the upper pressure core, and the upper slider of the wedge; the lower part includes the lower die body, the lower punch 6, the side shaping rotating wedge base 1, the side shaping reference punch 3, and the side flanging reference wedge 4; when the upper die moves downward, the upper pressure core first contacts the lower punch to press the plate, and the cylinder of the rotating wedge works to push the rotating wedge to the working position, and the side shaping reference punch on the rotating wedge is in place. The upper die continues to move downward, and the upper die insert contacts the guide surface of the side flanging reference wedge on the rotating wedge. The side flanging reference wedge is gradually reset under the drive of the upper die insert, and then the upper die continues to move downward, driving the upper slider and the working knife block installed on the upper slider to contact the plate and start working.

[0034] This patented new structure solves the common problem in the prior art that the structure cannot be designed due to insufficient space. By integrating two reference wedges that interfere with each other and cannot be designed into a new parent-child wedge structure, it can meet the requirement of reducing the number of structural mold processes, improving efficiency and reducing costs.

[0035] like Figure 3 As shown, in the actual production process, when the upper die moves downward with the press, the upper pressure core first contacts the lower punch to press the plate, and the cylinder of the rotating wedge works to push the rotating wedge to the working state. The side shaping reference punch on the rotating wedge is in place, and the upper die continues to move downward, and the upper die insert contacts the guide sliding surface of the side flanging reference wedge on the rotating wedge. The side flanging reference wedge is gradually reset under the drive of the upper die insert, and then the upper die continues to move downward, driving the upper slider and the working knife block installed on the upper slider to contact the plate and start working until the work is completed.

[0036] The present invention integrates two reference wedges that interfere with each other and cannot be designed into a new type of mother-and-child wedge structure. Different from the conventional mother-and-child wedges, this seed-and-child wedge is a reference wedge installed on another reference wedge, but can achieve retraction in two directions, which not only realizes the process, but also reduces the number of processes, reduces the production cycle, and reduces the cost.

[0037] The above is only an explanation of the preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0038] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
