Embodiment 1
[0026] see Figure 1~3 , in the embodiment of the present invention, a flat-bottomed drill raw material forming device includes a plastic-absorbing roller 1, and the side wall of the plastic-absorbing roller 1 is uniformly provided with several forming grooves 2, and the shape of the forming groove 2 matches the shape of the flat-bottomed drill, specifically There is no requirement, and it can be set according to the needs. For example, if there are eight star surfaces on the crown of the flat-bottomed drill, the forming groove 2 is provided with eight edges; the axial position of the blister roller 1 is provided with a first air flow channel 5; the forming The inner end of the groove 2 is provided with a ventilation hole 3 communicated with the first airflow passage 5; the upper and lower sides of the blister roller 1 are also respectively provided with a rotating shaft 7, and the rotating shaft 7 is fixedly connected with a connection plate 6 towards the end face of the blist...
Embodiment 2
[0028] see Figure 4~5 , on the basis of Example 1, the side wall of the plastic-absorbing roller 1 is located outside the forming groove 2 and is also fixedly provided with an annular boss 4 cooperating with the forming groove 2, and the outer ends of the annular boss 4 are flush; the plastic-absorbing roller 1 The side wall has a certain radian, so that the bottom of the flat-bottomed drill obtained by processing is not flat enough. By setting the annular boss 4, the bottom of the flat-bottomed drill blank formed after shoveling off the excess material is directly flat, and the quality is better. The flat-bottomed drill does not need subsequent processing and grinding. Reduce processing procedures and avoid defective products.
Embodiment 3
[0030] A kind of imitation diamond production equipment, comprises above-mentioned flat bottom drill raw material forming device.
