Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal stamping, in particular to assembly equipment for sheet metal stamping dies. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car bodies), etc. Its notable feature is that the thickness of the same part is consistent. The products processed by the sheet metal process are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used for assembly. Sheet metal parts often require the use of stamping dies during the processing process, and are stamped into specific shapes through stamping dies. Different processed parts require different production equipment and supporting dies. Therefore, during the production process, the corresponding supporting dies need to be frequently replaced.

[0003] However, some traditional molds are fixed by bolts, so when installing the mold, workers need to connect multiple installation bolts to the mold and multiple screw holes on the table at the same time, and then tighten the multiple bolts in sequence to complete the installation of the mold. If the mold needs to be replaced, the previously installed bolts must be removed, and then the new mold must be repositioned and installed. The operation is time-consuming and laborious, which increases the work intensity of the workers and makes the disassembly and assembly efficiency of the mold low. For this reason, we propose an assembly device for sheet metal stamping molds to solve the above problems. Utility Model Content
