Description

Technical Field

[0001] The invention relates to the technical field of pyrotechnic production, and specifically discloses an automatic disassembly device and a disassembly method for a riser funnel. Background Art

[0002] The riser funnel is the core auxiliary tooling for the injection process of some pyrotechnic products. The process of such pyrotechnic products requires that the riser funnel be removed from the product after the injection process is completed.

[0003] The current disassembly method is to manually clamp the product on a fixture, pry out the riser funnel with a crowbar, and knock out the residual explosives stuck in the riser funnel with a wooden hammer.

[0004] Since the pyrotechnics contained in some explosives have a high viscosity, the main body of the explosives needs to be fixed and the riser funnel needs to be pried out. The force applied during this process is large, and sparks are easily generated due to collision, which may cause an explosion. This method cannot achieve human-machine isolation, has safety hazards, and is not conducive to ensuring personnel safety. Therefore, it is necessary to develop a device to achieve the riser funnel disassembly operation with human-machine separation. Summary of the invention
