Description

Technical Field

[0001] The utility model relates to the field of drawing dies, in particular to a self-adjusting arc positioner and a die assembly with the positioner. Background Art

[0002] In the production process of automobile stamping parts, the positioning device of the drawing die is crucial.

[0003] For example, on the deep drawing die for the backup door, because the height of the product is relatively high, the drawing drop is large when the die is producing the product (deep drawing).

[0004] During the production process, a special arc-shaped positioning plate needs to be made to fix the position of the sheet metal.

[0005] The guide surface of the old-fashioned arc-shaped positioning plate is fixed and cannot adjust itself as the sheet metal shrinks, which makes the mold debugging process very troublesome and the positioning often fails to meet the expected requirements.

[0006] As long as there is a slight change in the edge of the sheet material, the position of the old curved positioning plate must be readjusted; this increases the risk of sheet metal being scrapped during debugging and production, and reduces the pass rate in product stamping production.

[0007] For example, patent: 201820953300.5 - A drawing die arc positioning plate and a rear wheel cover stamping die having the same disclosed content.

[0008] In summary, it can be known that the positioning plate of the traditional drawing die cannot move with the sheet material, so that the blank will leave the positioning surface and cause the blank to be inaccurately positioned again and can no longer play a positioning role, resulting in quality defects of the parts.

[0009] Therefore, in order to improve the above problems, it is necessary to optimize the design of the existing positioning plate structure. Utility Model Content

[0019] The angle adjuster includes a transverse plate and a connecting plate; the transverse plate and the connecting plate are arranged to intersect each other, and the transverse plate is pressed against the side surface of the movable guide plate; the transverse plate is connected to the positioning plate through the connecting plate.

In addition, in the utility model, the movable guide slide plate 2 is connected to the positioning plate 1 through an adjusting mechanism; the setting of the adjusting mechanism is convenient for adjusting the movable guide slide plate 2 is pressed, so that the movable guide slide plate 2 has a swinging ability. In subsequent use, the adjusting mechanism provides lateral support force to the movable guide slide plate 2, which is convenient for the movable guide slide plate 2 to laterally block and limit the sheet material. In addition, in the utility model, the adjusting mechanism includes a rotating pin 21 arranged on the positioning plate 1; the movable guide slide plate 2 is connected to the positioning plate 1 through the rotating pin 21; the setting of the rotating pin 21 enables the movable guide slide plate 2 to have the ability to swing around the rotating pin 21; therefore, in subsequent use, under the push of the pressing part, it can be squeezed on the side of the sheet material for a long time to realize the lateral blocking and limiting of the sheet material; finally, the problem of the positioner needing to repeatedly adjust its position is avoided.

[0035] In addition, the movable guide slide plate 2 described in the utility model is connected with a pressing part; the extrusion part mainly provides lateral driving force for the movable guide slide plate 2, so that the movable guide slide plate 2 can change its position as needed during subsequent use, and finally limit the lateral position of the sheet material; the extrusion part can be a structure such as the torsion spring 4 mentioned below, or it can be a pushing mechanism, which can mainly enable the movable guide slide plate 2 to lateral squeeze the sheet material during actual use.

[0038] At the same time, in the utility model, the angle adjuster 3 includes a transverse plate 33 and a connecting plate 32; the transverse plate 33 and the connecting plate 32 are arranged to intersect each other, and the transverse plate 33 is pressed against the side of the movable guide slide plate 2; the transverse plate 33 is connected to the positioning plate 1 through the connecting plate 32; based on the above design, the connection between the angle adjuster 3 and the positioning plate 1 is facilitated. During the actual connection, the connecting plate 32 is connected to the positioning plate 1 through the rotating shaft 31, and the free end of the transverse plate 33 is pressed against the side of the movable guide slide plate 2; and the end of the torsion spring 4 is pressed against the peripheral position of the connection between the connecting plate 32 and the transverse plate 33. Based on such a design, the torsion spring 4 is equivalent to pressing against the middle area of ​​the angle adjuster 3, so that the angle adjuster 3 can be better tilted, and finally the lateral support for the movable guide slide plate 2 is achieved.

[0039] Furthermore, in the utility model, a limit block 4 is provided on the positioning block; the setting of the limit block 4 plays a good limiting role, avoiding excessive tilting of the angle adjuster 3, and then avoiding the transitional swing of the movable guide slide 2 from affecting the lateral limitation of the sheet metal; in addition, in the utility model, the limit block 4 is arranged between the angle adjuster 3 and the movable guide slide 2; specifically, the limit block 4 is arranged above the transverse plate 33, and is in the space surrounded by the transverse plate 33, the connecting plate 32 and the movable guide slide 2, thereby realizing the limit of the tilting angle of the angle adjuster 3.

[0040] Furthermore, in the utility model, a side groove 13 is provided on the side of the positioning plate 1; the setting of the side groove 13 is equivalent to a storage groove, which is convenient for the installation of the angle adjuster 3, the limit block 4, the torsion spring 4 and the movable guide slide plate 2 on the positioning plate 1 in actual use. Specifically, in the utility model, the angle adjuster 3, the limit block 4, the torsion spring 4 and the movable guide slide plate 2 are arranged in the side groove 13; based on the above design, in actual connection, the angle adjuster 3 is fixedly connected to the side wall of the side groove 13, and the torsion spring 4 is connected to the side of the side groove 13 away from the movable guide slide plate 2 through the connecting shaft 41, the upper end of the angle adjuster 3 is connected to the inner wall of the side groove 13 through the rotating shaft 31, and the movable guide slide plate 2 is also connected to the inner wall of the side groove 13 through the rotating pin 21. At the same time, in the utility model, the angle adjuster 3 is pressed against the side of the movable guide slide plate 2; based on the above design, the swing control operation of the movable guide slide plate 2 is realized.

[0042] A mold assembly includes a mold body, on which the self-adjusting arc positioner is provided; in the utility model, a self-adjusting arc positioner is relatively arranged on both sides of the mold body; it is mainly used for lateral extrusion and positioning of a sheet material placed on the mold body.

[0043] specific:

[0044] The self-adjusting arc positioner disclosed in the utility model can effectively improve the debugging efficiency of the deep drawing die, shorten the cycle of die production, and improve the qualified rate of sheet metal stamping.

[0045] The specific working principle is as follows:

[0046] When the sheet metal is arranged on the mold body, the sheet metal is pressed on the movable guide slide plate 2, and the pressure of the sheet metal's own weight is transmitted to the angle adjuster, and the torsion spring 4 is squeezed during the angle adjustment period; during subsequent use, the torsion spring 4 provides a reverse force for the angle adjustment period, and the torsion spring 4 drives it to adjust itself according to the expansion and contraction of the sheet metal; during the entire processing process of the sheet metal, the movable guide slide plate 2 will closely follow the edge of the material and position the sheet metal in a self-adjusting manner.

[0047] The various parts of the self-adjusting arc positioner disclosed by the utility model are easy to process, most of the parts can be completed by wire cutting, and a small number of parts need CNC processing.

[0048] At the same time, the self-adjusting arc positioner disclosed in the utility model can make use of the principle of the deadweight of the sheet material to make the movable guide slide plate 2 movable and self-adjustable.

[0049] There will be no situation where the old-style arc positioning plate 1 has a fixed bone guide surface and the guide sliding surface often fails to position the sheet metal during mold trial, which results in the position of the old-style arc positioning plate 1 needing to be adjusted repeatedly, thus extending the mold manufacturing cycle.

[0050] And when the edge of the sheet material of the old-style arc-shaped positioning plate 1 changes, the position of the old-style arc-shaped positioning plate 1 will need to be readjusted, and even the guide sliding surface will need to be reprocessed.

[0051] The self-adjusting arc positioner disclosed in the utility model does not require the above-mentioned readjustment of position and reprocessing, and can effectively reduce the scrapping of sheet materials.

[0052] Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
