Description

Flatness adjustment module and equipment

technical field

The invention relates to the technical field of stamping and forming, in particular to a flatness adjustment module and equipment.

Background technique

1 to 2 are schematic diagrams of the structure of the existing battery top cover sheet. When the battery top cover sheet is produced, a stamping forming process is often used, that is, a flat metal plate is punched by a stamping die with a boss. In order to obtain the battery top cover sheet 1 with punched grooves 101 and/or through holes. When stamping on a metal plate, the back surface 1011 of the groove 101 located on the back of the punching groove 101 is prone to bending deformation to both ends due to the stress during stamping. The more serious the deformation is, the worse the flatness of the back surface 1011 of the groove is, and the less the bending deformation is, the better the flatness of the back surface 1011 of the groove is.

At present, there is no way to improve the stamping die to reduce the degree of bending deformation, but the flatness of the battery top cover sheet is very high in the industry, so the yield rate of the battery top cover sheet is low.

Therefore, there is a need for a flatness adjustment module to improve the flatness of the stamped parts.

There are a number of upper top blocks 303 for pushing down the back surface 2011 of the first groove. The top of the lower mold assembly 4 is provided with a lower mold cavity that matches the shape of the lower surface of the stamping part 2 , and the lower mold cavity corresponds to the second groove back surface 2021 of the second stamping groove 202 . There are a number of lower top blocks 403 for pushing up against the back surface 2021 of the second groove.

It should be noted that, if the stamped part 2 does not have the first stamping groove 201, the upper block 303 does not need to be provided; if the stamped part 2 does not have the second stamping groove 202, the lower block 403 does not need to be set.

Specifically, after stamping, the middle of the first slot back 2011 of the first stamping slot 201 will be arched upward, resulting in a lower flatness of the first slot back 2011. Therefore, to improve the flatness of the first slot back 2011 , it is necessary to reduce the upward arching of the middle of the back surface 2011 of the first groove. In the flatness adjustment module provided by the present invention, the stamped stamping part 2 after stamping is placed between the upper mold assembly 3 and the lower mold assembly 4, and then stamping is performed again, because the upper mold cavity and the lower mold cavity are respectively different from each other. The shapes of the upper and lower surfaces of the stamping die are matched, but the top block 303 is set at the back surface 2011 of the first groove, so the flatness of the upper surface of the stamping part 2 is basically unchanged except for the back surface 2011 of the first groove. , only the middle part of the back surface 2011 of the first groove will be properly recessed downward under the abutting action of the upper top block 303, and the downward recess can compensate for the amount of the upward arching, and finally cause the entire back surface of the first groove 2011 to be dented downward. Flatness is improved. Similarly, the lower top block 403 can also improve the flatness of the entire second groove back surface 2021 . Therefore, the flatness adjustment module provided by the present invention can improve the flatness of the stamped part 2 , thereby improving the yield of the stamped part 2 .

Preferably, the upper mold assembly 3 includes an upper mold plate 301 with an upper accommodating cavity at the bottom and an upper insert block 302 detachably installed in the upper accommodating cavity, and the upper mold cavity is located in the upper accommodating cavity.

It can be understood that for different stamping parts 2, the corresponding upper and lower mold cavities are different, so when the stamping part 2 is replaced, the upper die plate 301 and the lower die plate 401 can be used in common, only need to replace the corresponding one. The upper insert block 302 and the lower insert block 402 are sufficient.

In this embodiment, the upper insert block 302 is provided with a plurality of upper slots 3021 extending in the horizontal direction, and the upper top block 303 is inserted into the upper slot 3021; the lower insert block 402 is provided with a plurality of edges The lower slot 4021 extending in the horizontal direction, the lower top block 403 is inserted into the lower slot 4021 .

Preferably, the upper top block 303 and the lower top block 403 are both made of steel, and a fitting gap of 0.02mm˜0.05mm is set between the top block and the slot.

Specifically, the upper slot 3021 extends in the horizontal direction and is inserted into the upper top block 303, which facilitates the quick assembly and disassembly of the upper top block 303 and the insert block. Further, by replacing the upper top blocks 303 of different heights, the upward arching amount can be corrected to different degrees, that is, the higher the height of the upper top block 303, the greater the correction of the upward arching amount. The detachable plug-in structure of the upper top block 303 and the upper insert block 302 facilitates the staff to quickly replace the upper top blocks 303 of different heights according to the flatness requirements of the back surface 2011 of the first groove. Similarly, the detachable plug-in structure of the lower top block 403 and the lower insert block 402 facilitates the staff to quickly replace the lower top blocks 403 of different heights according to the flatness requirements of the back surface 2021 of the second groove.

Preferably, the slot width dimension of the upper slot 3021 gradually decreases from the slot bottom to the slot opening, and the shape of the upper end of the upper top block 303 matches the upper slot 3021 . The slot width of the lower slot 4021 gradually decreases from the slot bottom to the slot opening, and the shape of the lower end of the lower top block 403 matches the lower slot 4021 .

Specifically, the gradual reduction of the groove width from the groove bottom to the groove can ensure that the vertical direction is relatively fixed between the top block and the corresponding insert block, and the upper top block 303 and the upper insert block 302 do not have relative displacement in the vertical direction. Effective correction of the deformation of the back surface 2011 of the first groove is ensured, and the lower top block 403 and the lower insert block 402 do not undergo relative displacement in the vertical direction to ensure effective correction of the deformation of the back surface 2021 of the second groove.

Optionally, the number of the upper slots 3021 is more than the number of the upper top blocks 303 , and the number of the lower slots 4021 is more than the number of the lower top blocks 403 .

Further, the distance between two adjacent upper slots 3021 is equal, and the distance between two adjacent lower slots 4021 is equal.

It can be understood that the external structure and dimensions of many battery top cover sheets are almost the same, but the positions of the backside of the first slot 2011 and the backside of the second slot 2021 are different. Therefore, the positions of the upper top block 303 and the lower top block 403 should be appropriately changed. , so that the same set of upper inserts 302 and lower inserts 402 can be applied to several stamped and formed parts 2 such as battery top cover sheets with similar external and structural dimensions. Specifically, a number of upper slots 3021 arranged at equal intervals are arranged on the upper insert block 302, and a number of lower slots 4021 arranged at equal intervals are arranged on the lower insert block 402, and then according to the first slot back 2011 and the second slot of the stamping part 2 The position of the slot back 2021 is that the upper top block 303 and the lower top block 403 are inserted into the corresponding upper slot 3021 and lower slot 4021, and the top block is not inserted into the slot that is not opposite to the first slot back 2011 and the second slot back 2021 In this way, the same set of upper inserts 302 and lower inserts 402 can be applied to several stamped and formed parts 2 such as battery top cover sheets with similar external and structural dimensions, which improves the versatility of the flatness adjustment module, saves production resources, and improves economical efficiency. benefit.
