Description

Technical Field

[0001] The present invention relates to the technical field of machining, and particularly to a hot pressing device and method for processing vehicle glass covers. Background Art

[0002] Glass is used for wind shielding and light transmission. After certain special treatments, the glass has better properties. Among them, the use of vehicle glass is relatively common. Vehicle glass includes glass covers, vehicle windows, etc. When processing vehicle glass covers, first, the glass is heated, and then the heated glass is transported to a hot pressing device for hot pressing treatment.

[0003] The existing hot pressing device for glass uses a hot press. After the heated glass enters the hot press, the heated glass is conveyed into the mold of the hot press through a conveyor chain. The glass is in a planar shape as a whole. After high-temperature heating, due to thermal expansion, there is a slight swelling and warping at the outer edge of the glass. Since the bottom mold is the shape after the glass is bent, the hot press acts downward on the surface of the heated glass and bends along the mold. The first force received by the heated glass is at the bent part of the glass, which easily causes the outer edge of the glass to warp. There is already a slight swelling and warping of the glass during the initial heating, which easily leads to uneven pressure on the outer edge of the glass and the mold, and the heat on the glass cannot be dissipated in time. The existing hot pressing device directly acts completely on the glass, which easily causes the glass to crack during hot pressing forming. Therefore, we propose a hot pressing device and method for processing vehicle glass covers. Summary of the Invention

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-11 , the present invention provides a technical solution: a hot pressing device for processing vehicle glass covers, which is designed to include a hot pressing box body 1 and a conveyor chain 2. A feeding slope 11 is provided inside the hot pressing box body 1, and a visual window 12 is opened on the upper part of the hot pressing box body 1. The conveyor chain 2 is a conventional chain design, the front end of which is connected to a glass heating furnace, and the rear end is connected to a glass cooling and placing area. The entire conveyor chain 2 is not completely drawn in the attached drawings. One end of the conveyor chain 2 inside the hot pressing box body 1 is provided with a hot pressing groove body 21. A hot pressing die module is provided at the hot pressing groove body 21. The hot pressing die module includes an upper die module 3 and a lower die module 4. The upper die module 3 and the lower die module 4 can be bent and deformed. Through the design of the hot pressing groove body 21, it is beneficial for the upper die module 3 and the lower die module 4 to have a release space when bending and deforming.

[0037] The lower die module 4 is designed as shown in the attached Figure 5 and the attached Figure 6 as shown, and includes a plurality of lower die rollers 41 that are as high as the conveying rollers of the conveyor chain 2. The lower die rollers 41 are of an overall cylindrical structure. Therefore, after the glass enters the hot pressing box body 1 through the conveyor chain 2, it is continuously rolled in. By providing a positioning camera 5 in the middle part of the lower die module 4, when the glass is conveyed to the middle position, the positioning camera 5 detects the center line position of the glass, indicating that the glass has been completely conveyed onto the lower die rollers 41.

[0038] At both ends of the lower mold roller 41, there are lower mounting plates 42. Two adjacent lower mounting plates 42 are connected by a hinge plate 43. Two groups of stable support groups are mounted on the lower mounting plate 42, and the stable support groups are symmetrically distributed about the positioning camera 5. The stable support includes a connecting rod 46, and both ends of the connecting rod 46 are connected to the lower mounting plate 42. A strip-shaped groove 47 is formed on the lower mounting plate 42. Both ends of the connecting rod 46 are respectively connected with strip-shaped plates 48, and a sliding column 49 that slides at the strip-shaped groove 47 is connected to the strip-shaped plate 48. Thus, after the glass is completely conveyed to the lower mold roller 41, it opens from the middle position of the lower module 4 to both sides, and the sliding column 49 slides along the strip-shaped groove 47, so that the adjacent lower mounting plates 42 are adjusted in angle at the connection position of the hinge plate 43. The hinge plate 43 is designed as an arc section and is stacked in a mutually staggered manner. In this way, a single lower mold roller 41 can be adjusted in angle until the lower module 4 is bent into the shape required by the glass, as shown in the appendix Figure 5 As shown. Stop the bending deformation of the lower module 4. At this time, the upper module 3 needs to be bent and pressed down to the upper position of the glass. Through the combined action of the upper module 3 and the lower module 4, the glass is hot-pressed and bent.

[0039] The upper module 3 is designed as shown in the appendix Figure 7 As shown. It includes a plurality of upper mold rollers 31 that cooperate with the lower mold rollers 41, and upper mounting plates 32 are installed at both ends of the upper mold rollers 31. Two adjacent upper mounting plates 32 are connected by a hinge plate 43. The inside of the upper mold roller 31 is a cavity, and cooling air holes 33 are provided at the contact position between the upper mold roller 31 and the lower mold roller 41.

[0040] After the upper module 3 and the lower module 4 cooperate to form the shape required for the glass to be bent, at this time, it is necessary to cool the glass synchronously.

[0041] For cooling the lower position of the glass, a heat dissipation chamber 44 is formed on the lower mold roller 41, and heat dissipation holes 45 are formed at both ends of the heat dissipation chamber 44. A heat receiving member 6 is provided in the heat dissipation chamber 44. The heat receiving member 6 heats up and discharges the air in the heat dissipation chamber 44 to the heat dissipation holes 45; the heat receiving member 6 includes a temperature-sensitive arc-shaped piece 61 provided at the top of the heat dissipation chamber 44. A group of sliding pieces 62 are provided in the heat dissipation chamber 44, and the two sliding pieces 62 have opposite magnetic properties. A spring 63 is connected between the two sliding pieces 62.

[0042] After bending and fitting the temperature-sensitive arc-shaped sheet 61 at the bottom of the glass, the temperature between the two sliding sheets 62 increases, and the air pressure between them increases. When the gas pressure is greater than the magnetic attraction force of the two sliding sheets 62, the two sliding sheets 62 slide to both sides, discharging the air in the heat dissipation chamber 44 from the heat dissipation holes 45, thereby cooling the glass. After the air is discharged, the pulling force of the spring 63 increases, causing the two sliding sheets 62 to be pulled back. This process is repeated, facilitating the cooling of the bottom of the glass according to the real-time temperature of the glass during the deformation process.

[0043] For cooling the top of the glass, a power component 7 for driving the lower module 4 and the upper module 3 to wrap the glass is installed in the hot pressing box body 1, and a cooling component 8 for introducing cold air into the cavity of the upper die roller 31 is provided at the hot pressing box body 1. The cooling component 8 includes a cooling pump body 81 installed on the top of the hot pressing box body 1. The cooling pump body 81 is connected to an output pipeline 82, and two centralized pipelines 83 are connected to the output pipeline 82. A plurality of branch pipelines 84 are connected to the centralized pipelines 83. The branch pipelines 84 are connected to the cavity of the upper die roller 31. By continuously pumping out cooling gas by the cooling pump body 81, the cooling gas is successively distributed from the output pipeline 82 and the centralized pipelines 83 to a plurality of branch pipelines 84, and the cooling gas is continuously introduced into the cavity of the upper die roller 31 from the branch pipelines 84, and then the cooling gas is blown out from the cooling air holes 33 to the top of the glass, thereby cooling the top of the glass.

[0044] For the upper module 3 and the lower module 4 to be bent and deformed into the shape of the glass, it is adjusted by adopting the power component 7.

[0045] The power component 7 includes a first mounting plate 71 and a second mounting plate 72. The top of the first mounting plate 71 is connected to a mounting bracket 73, and the mounting bracket 73 is connected to the side wall of the hot pressing box body 1. The top of the second mounting plate 72 is connected to a telescopic rod 74, and the telescopic rod 74 is connected to the inner wall of the hot pressing box body 1. The two ends of the first mounting plate 71 are connected to first hydraulic rods 75, and the two first hydraulic rods 75 are respectively connected to the lower mounting plates 42 at the two ends of the lower module 4. The two ends of the second mounting plate 72 are connected to second hydraulic rods 76, and the second hydraulic rods 76 are respectively connected to the upper mounting plates 32 at the two ends of the upper module 3. The length of the first hydraulic rod 75 is greater than that of the second hydraulic rod 76.

[0046] Two winding motors 77 are connected to the outer wall of the hot pressing box body 1, and a roller shaft 78 is connected to the output shaft of the winding motor 77. The roller shaft 78 passes through the inner wall of the hot pressing box body 1. Two winding wheels 79 are connected to the roller shaft 78, and a steel wire sling 791 is wound on the winding wheels 79. The steel wire sling 791 is installed on the upper mounting plates 32 at the two ends of the upper module 3.

[0047] At the beginning, the lower mold roller 41 on the lower mold unit 4 is at the same height as the roller of the conveying chain 2. After the glass continuously enters, until the positioning camera 5 detects the position of the glass center line, since the glass is in a plate shape when not deformed, the positioning camera 5 completely captures the glass. After the glass center line enters the positioning camera 5, at this time, by simultaneously starting the first hydraulic rod 75 and the second hydraulic rod 76, after the first hydraulic rod 75 contracts, the winding adjustment starts from both ends of the lower mold unit 4. The second hydraulic rod 76 simultaneously drives the upper mold unit 3 for winding adjustment, and the winding motor 77 starts to rotate, so that the wire sling 791 is released. Until the upper mold unit 3 fits onto the glass surface, continuously contract the first hydraulic rod 75 and the second hydraulic rod 76, so as to avoid applying pressure to the glass at one time, facilitate the release of the stress of the glass after heating, and is beneficial to the hot pressing forming of the glass.

[0048] After the hot pressing is completed, a swing chamber 9 is provided at one end of the lower mold unit 4 in the heat dissipation chamber 44, and a swing groove 91 is opened at the top of the swing chamber 9. A swing motor 92 is installed in the swing chamber 9, and a swing plate 93 passing through the swing groove 91 is connected to the output shaft of the swing motor 92. The swing motor 92 drives the swing plate 93 to swing, thereby conveying the glass out of the hot pressing box body 1.

[0049] A hot pressing equipment method for processing vehicle glass covers includes the following steps:

[0050] A: Heat transfer of the heated glass, and the heated glass is conveyed into the hot pressing box body 1 through the conveying chain 2.

[0051] B: Glass positioning, and the positioning camera 5 determines the center position of the glass.

[0052] C: Wrapping the heated glass, and the power assembly 7 hoists the lower mold unit 4 and the upper mold unit 3 to wrap the heated glass.

[0053] D: Glass bottom heat dissipation, and the heat receiving member 6 discharges the air in the heat dissipation chamber 44 to the heat dissipation holes 45 to dissipate heat from the bottom of the glass.

[0054] E: Glass top heat dissipation, and the cooling assembly 8 passes cold air into the cavity of the upper mold roller 31 to dissipate heat from the top of the glass.

[0055] F: After the hot pressing is completed, the power assembly 7 hoists the upper mold unit 3, and the glass is hot pressed into shape.

[0056] This embodiment provides a hot pressing device and method for processing vehicle glass covers. Compared with the prior art, by providing an upper module and a lower module that can be bent and deformed, after the positioning camera detects the central position of the glass, the provided power assembly drives the upper module and the lower module to wrap the glass and gradually bend from the central position of the glass to both sides, thereby avoiding the force of hot pressing deformation from acting on the position where the glass expands due to high temperature first. The heat dissipation chamber of the lower module receives the heat at the bottom of the glass and quickly dissipates the heat at the bottom of the glass. Moreover, the cooling assembly cools the top position of the glass by the upper module, which is beneficial to cooling the top and bottom of the glass during the hot bending process and avoiding the problem of glass cracking caused by the untimely dissipation of heat during the hot pressing process. The swing motor swings in the provided swing chamber, which is beneficial to transporting the glass out after the glass is formed.
