[0002] The safety part of the pneumatic tool is a three-dimensional structural component, which is composed of an end structure, a middle structure, a connecting part and a tail structure. Its existing preparation process requires nine sets of molds to be stamped separately, which greatly increases labor and production. Equipment has to be invested, divided into nine times of stamping, which increases the repositioning error and processing error of the product and increases the production cost of semi-finished products

The invention discloses a die for a safe insurance relieving part of a pneumatic tool. The die comprises an upper die base and a lower die base. An upper clamping plate is arranged at the bottom of the upper die base. A trimming and piercing die body, a contour piercing die body, a bending die body and a blanking and slitting die body are arranged at the bottom of the upper clamping plate in sequence in the feeding direction. A stripper plate is further arranged below the upper clamping plate. A lower die plate is arranged on the surface of the lower die base. Lower die portions matched with the trimming and piercing die body, the contour piercing die body, the bending die body and the blanking and slitting die body are arranged on the lower die plate. The upper die base is connected with the lower die base through inner guide columns. Multiple locating mechanisms are further arranged on the lower die plate. A method for using the die comprises the steps of firstly, trimming and piercing; secondly, partial contour piercing; thirdly, side edge flattening; fourthly, finishing cutting; fifthly, adjustment; sixthly, trimming; seventhly, supporting cutting; eighthly, bending; and ninthly, blanking and slitting. According to the die and the method for using the die, the structure is simple, design is reasonable, and labor and production investment are greatly reduced.
Description
technical field [0001] The invention relates to the field of moulds, in particular to a safety part mold for a pneumatic tool and a method for using the same. Background technique [0002] The safety part of pneumatic tools is a three-dimensional structural component, which is composed of end structure, middle structure, connecting part and tail structure in sequence. Its existing preparation process requires nine sets of molds to be stamped separately, which greatly increases labor and production. Equipment has to be invested, and stamping is divided into nine times, which increases the repositioning error and processing error of the product and increases the production cost of the semi-finished product. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and to provide a safety part mold for pneumatic tools and its use method. The present invention has simple structure, reasonable design, and greatly...
