The article probes into the research progress at home and abroad,the development background and market requirement of the fur punching also analyses the condition of this machine about development design and user its purpose and significance of design clear. Through the medium of analyses of pelt structural ,we present acupuncture hot medicated press which is a punch method adopt taper opposition pin spurt and opposition pin hot medicated press method pletion solve the problem that is punch on the cutis plate without injuring its fleece. with the handle of grooved pulley and cam, we realize the multiplex potential ran of the machine which greatly advance the efficiency and quality of tapping on the cutis plate. incorporation produce practice, I gave out monolithic construction and each partial designing of punching machine which based on the pare of manifold design of each several part of mechanical structure. I made option and check the major parts of the punching machine by calculating the parameter. in the end, I use Catia realize threed modeling and assembly of the punching machine, and I use Autocad realize twodimensional engineering drawing. In short, this article is for the purpose of designing one kind of new fur punch press to be able to help the pany to enhance the production efficiency, reduces the production cost the.
