Description
Technical Field
The invention relates to a positioning device for a mobile phone stamping part, in particular to a rapid positioning device for a multi-station mobile phone stamping part.
Background
The mobile phone stamping part is a forming processing method which applies external force to plates, strips, pipes, profiles and the like by a press and a die to cause the plates, the strips, the pipes, the profiles and the like to generate plastic deformation or separation, thereby obtaining workpieces (mobile phone stamping parts) with required shapes and sizes. Stamping and forging are plastic working (or called pressure working), and are called forging and pressing. The stamped blanks are mainly hot and cold rolled steel sheets and strips.
Compared with castings and forgings, the mobile phone stamping part has the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with ribs, undulations or beads that are otherwise difficult to manufacture, to increase their rigidity. Because of the adoption of the precise die, the precision of the workpiece can reach the micron level, the repeated precision is high, the specification is consistent, and the hole nest, the boss and the like can be punched.
Cold hand stamping is generally no longer machined or requires only a small amount of machining. The precision and the surface state of the hot mobile phone stamping part are lower than those of the cold mobile phone stamping part, but the hot mobile phone stamping part is still superior to castings and forgings, and the cutting machining amount is small. The stamping is an efficient production method, and multiple stamping processes can be completed on one press by adopting a compound die, particularly a multi-station progressive die, so that full-automatic production from uncoiling, leveling, blanking to forming and finishing of a strip is realized. High production efficiency, good working conditions and low production cost, and can produce hundreds of pieces per minute generally.
The existing mobile phone stamping parts need to pass through the positioning device before stamping, in order to guarantee the stamping effect and the quality of the obtained mobile phone stamping finished products, the stamping parts needing stamping are positioned in advance, then stamping is carried out, and the displacement in the stamping process is avoided.
