The utility model discloses a full -automatic pearl puncher, including puncher base and be provided with the mobile support arm of puncher base upper side four corner position department, the mobile support arm's lower side front and back both ends middle position department is provided with the receiving hopper respectively, the middle position department of receiving hopper is provided with the centralizing dish, the upper side position department of mobile support arm's left and right two ends is provided with the feeding mechanical arm of connecting external power supply power supply, and is connected through the tension spring between mobile clamp bar and fixed clamp bar, under the synergic effect of contact ring and pressure spring, when placing the pearl of different shape size, tension spring can be according to the actual contour and size of pearl and carry out the telescopic adjustment of self -adaptation. For example to oval pearl, the elastic deformation of spring can fill up the gap produced because of the irregular shape, ensure that the pearl is closely clamped, and do not need like traditional equipment, for different shape pearl frequently change special clamp, greatly improved the convenience of operation.

The application discloses a multi-gradient sharp corner punching die for amorphous alloy based on notch sensitivity and application thereof to punch amorphous alloy, soft magnetic material or metal thin strip. The multi-gradient sharp corner punching die for amorphous alloy based on notch sensitivity comprises a die body and a die front end; the die front end is provided with a circular punching end face; a plurality of sharp corners with top angles towards a punching direction are arranged on the edge region of the punching end face along the circumference thereof, the sharp corners are periodically arranged from high to low and then to high, and the higher the sharp corner is, the smaller the top angle is.

This invention provides a sheet-formed tableware and its manufacturing method. The tableware includes a main body and a handle, with the main body located at one end of the handle. Both the main body and the handle are formed by molding or vacuum forming from a single sheet of material. The tableware is formed in one pass by a die. Along the length of the tableware, one part is a punching area, and the other part is a shearing area. The die has a movable mold and a punching block that can move relative to each other. The punching block has a punching surface for punching the tableware. The punching surface corresponding to the punching area of ​​the tableware is perpendicular to the movement direction of the movable mold, and the punching surface corresponding to the shearing area of ​​the tableware is inclined to the movement direction of the movable mold. The manufacturing method of the tableware includes making a blank of the sheet material, molding or vacuum forming the blank into a three-dimensional shape, placing the sheet material in the die, and moving the movable mold towards the punching block, so that one part of the sheet material is punched and another part is sheared, obtaining the tableware in one pass. This invention can reduce the manufacturing cost of tableware and makes the tableware smooth and strong.
