Multi-Lane Shell Stamping Without a Movable Locating Cup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shell manufacturing equipment faces challenges in achieving high production capacity, compactness, precision, and stability, particularly due to the difficulty of mounting and dismounting dies in compact multi-lane structures.
Innovation Solution
A stamping device and multi-lane shell stamping system are introduced, featuring a compact six-lane structure without a movable locating cup. The system includes a stamping device with integrally formed upper dies and coaxially arranged cylindrical dies, and a multi-lane shell stamping system with synchronous belts and independently adjustable shell distributors.

Engineering Contradiction Analysis
1Manufacturing precision
If a movable locating cup is used to correct the position of the shell, then the locating precision is improved, but the difficulty of mounting and dismounting the dies increases
Solution Approach 1:
The patent removes the movable locating cup from the system and integrates the locating function directly into the upper die structure. The upper die is designed with a larger outer diameter that directly contacts and locates the shell, eliminating the need for a separate locating cup component and simplifying the mounting and dismounting process.
Solution Approach 2:
The locating function is merged with the upper die structure itself. The upper die serves dual purposes: both as the stamping tool and as the locating mechanism through its larger outer diameter that engages with the shell, combining two functions into one component.
2Ease of manufacture
If the outer diameter of the upper die is increased to eliminate the locating cup, then the mounting and dismounting difficulty is reduced, but the device complexity may increase
Solution Approach 1:
The locating function is merged with the upper die structure itself. The upper die serves dual purposes: both as the stamping tool and as the locating mechanism through its larger outer diameter that engages with the shell, combining two functions into one component.
Solution Approach 2:
The upper die is designed to perform multiple functions: stamping the shell and simultaneously locating it through its larger outer diameter. This multi-functional design eliminates the need for separate locating components, reducing overall system complexity despite the increased diameter of the upper die.

AI summary
This application discloses a stamping device and a multi-lane shell stamping system, and the stamping device is used for simultaneous stamping of multiple shells, comprising a plurality of stamping die sets arranged in an array. Each stamping die set comprises an upper die and a lower die. The upper die is integrally formed, and the outer diameter of the upper die is larger than that of the lower die, and the bottom edge of the upper die forms a locating part for the curling of the shell to be processed. The present invention eliminates the movable locating cup, which can avoid the difficulty of mounting and dismounting the die due to the compact six-lane structure. At the same time, it adopts the method of directly increasing the diameter of the upper die, which not only avoids the mounting and dismounting of the locating cup, but also realizes the locating effect of the shell.
