The invention discloses a copper screw processing device. The device comprises a first upper mold, a second upper mold, a lower mold and a machine tool. The first upper mold comprises a first upper mold body, a first mold core and a second mold core, the first mold core is cylindrical, a semi-spherical cavity is formed in the first mold core to precisely accommodate the semi-spherical second moldcore, and the interior of the lower end of the second mold core is provided with a third cylindrical cavity and a fourth cylindrical cavity. The second upper mold comprises a second upper mold body, athird mold core and a fourth mold core, the interior of the lower end of the fourth mold core is provided with a flat cylindrical cavity which is communicated with a second cylindrical cavity, the interior of the lower end of the third mold core is provided with a circular platform cavity, and the circular platform cavity is provided with a downwards opening to be communicated with the second cylindrical cavity. The lower mold comprises a lower mold body and a fifth mold, the fifth mold is sequentially provided with a toothed cylindrical cavity, a first cylindrical cavity, a screw cylindricalcavity, a second reversed circular platform cavity and a fifth mold core cavity from the upper end to the lower end. By means of the device, the problems of non-smooth screw tops, the failure of coldheading molding at one time and the failure of meeting production demands of an existing processing device are solved.
Description
technical field [0001] The invention relates to the field of standard parts processing, in particular to a copper screw processing device and method Background technique [0002] In the standard parts production and processing plant, there is a red copper screw product for automotive touch starters, such as Figure 5 As shown, due to the high smoothness of the head surface of this product, it has been impossible to realize the one-time forming of the head through cold heading for a long time, and it is necessary to rely on secondary processing (such as: machining equipment turning) to achieve the head that meets the smoothness requirements of the top end surface. final shape. The original production process is divided into: cold heading → thread rolling → secondary processing → surface treatment → inspection → packaging, a total of 6 processes. The original cold heading production process is: the first step is to select a red copper wire with a diameter of D1 = 10.5mm and c...
