Abstract

The invention discloses a stamping needle for rod material single point stamping. The stamping needle comprises a stamping head, a transition rod and a fixing rod. One end of the transition rod is connected with the fixing rod. The other end of the transition rod is connected with the stamping head. The diameter of the transition rod is less than that of the stamping head. The diameter of the stamping head is less than that of the fixing rod. The invention further discloses a machining technology of the stamping needle for rod material single point stamping. The technology comprises the following steps of S1, material sawing, S2, end face leveling, S3, center hole drilling, S4, outer circle turning, S5, blank machining, S6, quenching, S7, outer circle fine-grinding, and S8, two-end-face plane-grinding. According to the stamping needle, the stamping head is short but can achieve long-strock stamping. Compared with a traditional step type three-section mode, the hole stamping head is short, and mounting is convenient. According to the machining technology, a grinding machine is adopted to finely grind the outer circle of the stamping needle, and therefore influence on the diameter ofthe stamping needle caused by secondary clamping due to secondary fine turning can be avoided, and machining accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of bar material single-point stamping, in particular to a bar material single-point stamping punching needle and a processing technology thereof. Background technique [0002] Stamping processing is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet to deformation force and deform in the mold, so as to obtain product parts of a certain shape, size and performance. Sheet metal, mold and equipment are the three elements of stamping processing. [0003] According to the stamping processing temperature, it is divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a commonly used stamping method for thin plates. It is one of the main methods of metal plastic processing (or pressure processing), and ...
