Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and particularly relates to a replacement mechanism for a stamping die. Background Technique

[0002] A stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly known as a cold punching die). Stamping is a pressure processing method that applies pressure to materials by using a die installed on a press at room temperature to cause separation or plastic deformation, so as to obtain the required parts.

[0003] However, when the existing stamping dies are in use, due to different product specifications and sizes, multiple replacement operations are required. The existing dies are not convenient for moving and disassembling operations. Workers are very inconvenient, time-consuming and laborious when disassembling, overhauling, maintaining or cleaning the die head. Therefore, a replacement mechanism for a stamping die is needed to improve the above problems. Content of the Utility Model

A fixing plate 11 is fixedly installed on the moving plate 5. Two telescopic columns 13 are symmetrically and fixedly installed on the fixing plate 11. The two telescopic columns 13 are connected by a baffle 12. Springs 14 are sleeved on the two telescopic columns 13. The two ends of the two springs 14 are respectively fixedly connected to the fixing plate 11 and the baffle 12. By sliding the baffle 12, the baffle 12 is moved away from the T-shaped groove, so that the T-shaped block 7 is slidably connected to the T-shaped groove, and the insertion block 8 passes through the through hole. Rotate the first bolt 10 to connect the insertion block 8 with the mounting plate 9, thereby performing a preliminary fixing operation on the upper die 6. Loosen the baffle 12 to block the T-shaped block 7. The baffle 12 is connected to the moving plate 5 by two second bolts 15.
