Description
Technical Field
The invention relates to a metal ring sheet manufacturing die and a method for manufacturing a metal ring sheet by using the die, which are particularly suitable for stamping the metal ring sheet without closed-loop requirements.
Background
In the traditional manufacturing industry, the metal ring sheet is manufactured by rolling a metal strip first and then stamping the metal strip into the metal ring sheet, and in order to obtain the strip with proper size, the metal is rolled for multiple times, and the steps of annealing, cleaning and the like are also needed, so that the investment of equipment is high in price, the working procedure is complex, and the energy consumption is high. Meanwhile, the yield of the mode of processing the strip material into the metal ring sheet is limited by the shape and the size of the metal ring sheet, and the metal ring sheet is not always high.
The wire drawing machine for producing the metal wire is relatively low in price, the wire drawing die is cheap and durable, and the processing cost is far lower than that of the metal strip. And the yield of the metal ring sheet punched by the metal wire rod after the ring is made is close to 100%, so that the waste of the strip material for punching the ring sheet is reduced, the yield is improved, and the production energy consumption is reduced. Therefore, the metal wire rod is directly used for punching the metal ring sheet without closed loop requirements, so that the energy is saved and the cost is saved.
Although many enterprises at home and abroad try to use metal wires to manufacture annular metal sheets, the design of stamping dies faces some problems. (1) The unreasonable arrangement of the unloading mechanism of the stamping die can not lead the stamped annular metal sheet to be smoothly separated from the female die, thereby influencing the production efficiency of the annular metal sheet; (2) The placement position of the metal wire rod ring is difficult to fix, and irregular ring sheets such as eccentric holes, notches and the like are easy to appear after stamping; (3) Because the stamping die is designed with a fit clearance, the stamped annular metal sheet is subjected to joint filling at the fit clearance of the convex-concave die to form burrs due to extrusion of the metal wire ring. The patent numbers are as follows: in the patent of CN 200810197501.8, the problems are easy to occur, and the prepared annular metal sheet can be recovered to a certain extent, namely, the opening is enlarged.
