Problems solved by technology

[0003] Blister plate is a common forming device in the production of flat-bottomed drills. It has a large production capacity and can effectively reduce processing difficulty; however, the blister plate has a disc-shaped structure, and the air flow space is large when vacuuming, which consumes more energy; and after the blank is formed Demoulding is cumbersome and often requires specific tools to eject the billet from the forming tank, which is time-consuming and easily causes billet damage, and the defective rate is high, which is not conducive to improving the overall economic benefits

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.

Abstract

The invention discloses a flat-bottom diamond raw material forming device, and relates to the technical field of imitation diamond production. The flat-bottom diamond raw material forming device solves the problem that an existing vacuum forming plate blank is hard to demold after forming. The flat-bottom diamond raw material forming device comprises a vacuum forming roller. A plurality of forminggrooves are uniformly formed in the lateral wall of the vacuum forming roller. The shape of the forming groove is matched with the shape of the flat-bottom diamond. A first airflow channel is formedat the axial of the vacuum forming roller. Ventilation holes communicating with the first airflow channel are formed in the inner ends of the forming grooves. The vacuum forming plate is replaced withthe vacuum forming roller, the first airflow channel is arranged in the vacuum forming roller, during air exhausting, the air flowing space is small, and therefore energy consumption is reduced and energy is saved. The device is controlled to rotate, and under action of the centrifugal effect, blanks in the forming grooves and the ventilation holes are discharged, and demolding is convenient andquick. Integral processing efficiency is further improved. Jacking by an external object is not required, and damage is avoided.

Description

technical field [0001] The invention relates to the technical field of imitation drill production, in particular to a flat bottom drill raw material forming device. Background technique [0002] Imitation diamond, as the name suggests, is to imitate natural diamonds with materials that have a similar diamond appearance. It is usually used to make jewelry, or embellished on bags and clothing. Imitation diamonds are made of various materials, including plastic, glass, etc. The shape can be divided into two categories: sharp-bottomed drills and flat-bottomed drills. Flat-bottomed drills are very common in the field of jewelry, and the demand is also great. In order to improve the production efficiency of flat-bottomed drills, the production of flat-bottomed drills generally adopts blister technology. The main principle is that raw materials are heated. After softening, vacuum adsorption is used on the surface of the mold, and it is shaped after cooling. [0003] Blister plate ...
