Adjustable pressing mechanism for glass hot bending machine

Technical Field

The utility model relates to a glass hot-bending forming field, in particular to adjust pressing mechanism.

Background

At present, in the field of glass hot bending, particularly in the hot bending molding of ultrathin glass such as mobile phone screen glass and the like, a common process is to put planar glass to be processed between an upper die and a lower die, soften the glass by heating the dies in sections, apply certain pressure to the upper die during softening to carry out hot bending molding on the softened glass, and then carry out cooling to obtain a product.

In the sectional heating process, the whole mold needs to be heated to reach the sectional preset temperature, and the heating mode usually adopts two modes of contact heat conduction heating or non-contact heat radiation heating of the heating module and the mold. The non-contact thermal radiation heating mode heats the die comprehensively and uniformly, but has low thermal conduction efficiency and long time consumption; and the contact conduction heating mode has high thermal conductivity and short time consumption, but the fitting degree of the heating module and the mold is tested very much, when only one part of the heating module is fitted with the mold, and the other part is not contacted, the temperature of the contact part is quickly raised, the non-contact part is subjected to radiation heating, the temperature is slowly raised, and the temperature of part of the position cannot meet the requirement.

In the prior art, in order to solve the problem that a heating module is tightly attached to a mold, a spring is added into the heating module, and the problem of a contact gap is solved through the contraction of the spring, but the pressure of a pressed position (a force application point position) of the spring is strong by the method, and an excessive indentation is generated on a corresponding position on the surface of formed glass, so that a defective product is generated; the other mode is that the distance between the pressing mechanism and the heating plate is finely adjusted in a non-working state, the position of a gap is found out by pressing the heating module and the die for multiple times, and then the leveling is realized by adjusting the gap between the pressing mechanism and the heating module.

Example 1

In the embodiment, as shown in fig. 1 and fig. 2, the device comprises a device housing 1, wherein a first through hole 11 and a second through hole 12 are formed in the device housing 1, a graphite copper sleeve 14 is further formed in the first through hole 11, and a movable guide post 2 penetrates through the graphite copper sleeve 14 and is connected with a fixing plate 3 at the lower end thereof; the fixing plate 3 is provided with a first threaded hole 31 and a second fixing hole 32; the adjusting mechanism 4 comprises a movable pressure lever 41, a fixed block 43 and a fixed bolt 44, wherein the fixed block 43 is provided with a third threaded hole 431 and a first fixed hole 432; the heating module 5 is provided with a second threaded hole 51, and a movable groove 52 is also arranged below the second threaded hole 51; the movable pressure lever 41 penetrates through the third threaded hole 431, the first threaded hole 31 and the second threaded hole 51, the lower end part of the movable pressure lever is arranged in the movable groove 52, a spring 42 is also arranged below the movable pressure lever 41 in the movable groove 52, and the periphery of the movable pressure lever 41 is provided with external threads matched with the third threaded hole 431, the first threaded hole 31 and the second threaded hole 51; the fixing bolt 44 is threaded with the second fixing hole 32 through the first fixing hole 432, and the first fixing hole 432 is not threaded; as shown in fig. 1, the fixing block 43 has a structure similar to a quadrangular prism, and is located on a surface of the fixing plate 3 that contacts with the fixing plate, specifically, a position that contacts with the fixing plate 3 is located on the right side of the fixing bolt 44, and a position that does not contact with the fixing plate 3 is located on the left side of the fixing bolt 44, and the whole structure is similar to a structure in a shape of "7"; a second through hole 12 is provided directly above the adjustment structure.

The number of the adjusting mechanisms is 4, and the adjusting mechanisms are arranged at four corners of the fixing plate 3, namely are connected with four corners of the heating module 5.

When the equipment normally operates, a protective bolt 13 is further arranged on the second through hole 12, and the protective bolt 13 is in threaded connection with the second through hole 12. The internal operating state of the device can be observed from the outside. Under the normal condition, activity guide pillar 2 drives fixed plate 3 and heating module 5 and reciprocates, when laminating the mould, activity guide pillar 2 can remove to predetermineeing the position downwards, and the mould is also in the assigned position this moment, activity guide pillar 2 is rigid connection with fixed plate 3, and is connected for spring 42 between heating module 5 and the fixed plate 3 in fact, spring 42 contracts, can apply a decurrent pressure to heating module 5, this pressure only makes heating module 5 laminate on the mould, great pressure is not.

In a normal case, since the fixing bolt 44 is screwed with the second fixing hole 32 through the first fixing hole 432 and the contact point of the fixing block 43 with the fixing plate 3 is at the right side of the fixing bolt 44, a lever-like structure is integrally formed, the contact point at the right side is a fulcrum, and the fixing bolt 44 provides a downward pressure, so that the fixing block 43 has a tendency to move to the lower left side.
