Forming device

Abstract

The invention belongs to the technical field of automobile glass manufacturing, and discloses a forming device. The forming device comprises a forming die, wherein the forming die is arranged at the downstream of a heating furnace; the forming die comprises a male die mechanism, a pre-forming mechanism and a female die mechanism; the pre-forming mechanism is positioned below the male die mechanism, and the pre-forming mechanism is arranged to support workpiece and pre-form the workpiece; the female die mechanism is positioned below the male die mechanism, and the female die mechanism is arranged to penetrate through the pre-forming mechanism from the lower part of the pre-forming mechanism to support the workpiece; and the female die mechanism can be closed together with the male die mechanism for compression forming of the workpiece. According to the forming device, the mode that forming is carried out by the forming die outside the heating furnace is adopted, so that the forming temperature of glass is low, the glass forming temperature is guaranteed to be in a good temperature range, unstable factors of glass forming are reduced, stability of forming of the workpiece is guaranteed, and therefore the forming quality of the finished workpiece is improved.

Description

technical field [0001] The invention relates to the technical field of automobile glass manufacturing, in particular to a forming device. Background technique [0002] With the vigorous development of the automobile industry, the demand for automobile glass is also increasing. Since automobile glass is usually a curved surface structure, it brings greater difficulty to production and processing. [0003] In the actual production process of automobile glass, after the glass is heated and softened by the heating furnace, the concave mold moves to the right below the convex mold, and the blowing mechanism blows the glass up through the airflow, so that the glass can contact the convex mold, and then passes through The convex mold and concave mold of the forming mold are pressed and formed, and then the concave mold is translated back to the original position and the glass is quenched, tempered and cooled, and then the production of tempered glass is completed. The existing for...

Problems solved by technology

[0004] 1) The whole forming device is installed in the heating furnace, the length of the heating furnace is long, the energy consumption is large, the production cost is high, and the forming temperature of the glass is high, so the deformation of the glass forming is large and the stability is poor

[0005] 2) The concave mold needs to move back and forth to close with the convex mold and then press the glass. The reciprocating horizontal movement of the concave mold will cause the mold clamping state of the concave mold and the convex mold to be unstable, and the blowing mechanism will blow up the glass, which will easily cause the glass to move. , affecting the quality of the glass forming effect, and the yield is low

In addition, the working time of the reciprocating movement of the die and the blowing mechanism is longer, and the production efficiency is lower
