Description

Technical Field

[0001] The utility model relates to the technical field of automobile glass manufacturing, in particular to an out-of-furnace pressing and forming device for automobile tempered glass. Background Art

[0002] With the vigorous development of the automobile industry, the demand for automobile glass is also increasing. Since automobile glass usually has a curved structure, it brings great difficulty to production and processing. In the actual production and processing of automobile glass, after the glass is heated and softened in a heating furnace, the die moves to the bottom of the punch, and the blowing mechanism blows up the glass through the airflow so that the glass can contact the punch. After that, it is pressed into shape by the punch and die of the forming mold, and then the die moves back to the initial position and the glass is quenched and tempered to complete the production of tempered glass.

[0003] During the use of the existing device, the male and female molds need to be cleaned frequently to prevent impurities such as glass slag or dust from sticking to the two. Impurities on the extrusion surface may cause uneven contact between the mold and the glass plate during pressing. This will form uneven pressure and contact points on the surface of the glass plate, which may lead to unsatisfactory molding effects, leaving marks or uneven surfaces. In addition, since the concave surface is generally set at the bottom, it is more convenient to clean, but the male mold generally moves upward after extrusion, which makes cleaning very inconvenient. Therefore, a device for pressing and forming automotive tempered glass outside the furnace is needed to improve the above problems. Utility Model Content

[0004] The utility model aims to provide a device for pressing and forming automobile tempered glass outside a furnace, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An automobile tempered glass furnace external pressing molding device comprises a heating box, a support assembly is arranged on one side of the outer wall of the heating box, a pressurizing assembly is mounted on two symmetrical outer walls of the support assembly, a convex mold is mounted on the pressurizing assembly, and a cleaning assembly is arranged between the convex mold and the pressurizing assembly;

[0007] The cleaning component includes an installation frame, a plurality of springs are evenly distributed on the inner wall of the installation frame, a mounting block is fixedly installed on one end of the plurality of springs away from the installation frame, a cleaning sponge is fixedly installed on one end of the installation block away from the spring, and a mounting frame is fixedly installed on the outer walls of the installation frame that are symmetrical to each other.

[0008] As a preferred solution of the present utility model, the pressing assembly includes a connecting frame, two mounting frames are symmetrically installed on the outer walls of the two symmetric sides of the connecting frame respectively, a hydraulic telescopic rod is fixedly installed at the center of the inner wall top of the connecting frame, and a punch is fixedly installed on the telescopic end of the hydraulic telescopic rod.

[0009] As a preferred solution of the present utility model, extrusion blocks are fixedly installed on both sides of the top of the punch near the two mounting frames respectively, and the mutually remote sides of the two extrusion blocks are respectively wedge-shaped.

[0010] As a preferred solution of the present utility model, the supporting assembly includes a supporting frame and a female die, a connecting frame is fixedly installed on the outer walls of the two symmetric sides of the supporting frame, a connecting frame is fixedly installed in the inner wall of the female die, through holes are symmetrically opened on both sides of the top of the connecting frame, and a moving frame is clamped in the two through holes.

[0011] As a preferred solution of the present utility model, the moving frame is in a "U" shape, top support blocks are symmetrically opened at the cross bar of the moving frame, a top support block is fixedly installed above one side of the supporting frame close to the through hole, and the top of the top support block contacts the moving frame.

[0012] As a preferred solution of the present utility model, a conveying mechanism is arranged at the bottom of the inner wall of the heating box.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] In the present utility model, by arranging a cleaning assembly and extrusion blocks in the external pressing and forming device of the automotive tempered glass furnace, during the use process, when the punch moves downward, the hydraulic telescopic rod will also descend along with the punch. During the descending process, the hydraulic telescopic rod will slide the extrusion spring towards the inside of the mounting frame. As the punch descends, the punch will get rid of the contact with the cleaning sponge. At this time, the punch will cooperate with the female die to press the glass. After completion, the hydraulic telescopic rod drives the punch to move upward, and along with the upward movement of the punch, the extrusion blocks will also move upward. As it rises, the mounting block will push the cleaning sponge towards the punch under the action of the spring, realizing the rapid cleaning of the glass slag debris or dust on the surface of the punch, solving the problem that since the female die is generally arranged below and is relatively convenient to clean, but the punch generally moves upward after extrusion, thus causing great inconvenience in cleaning.

[0024] Example: See Figure 1-4An off-furnace press-forming device for automotive tempered glass shown includes a heating box 1. On one side of the outer wall of the heating box 1, a support assembly 5 is provided. A pressing assembly 3 is cooperatively installed on the outer walls of the two symmetric sides of the support assembly 5. A punch 6 is cooperatively installed with the pressing assembly 3. A cleaning assembly 4 is arranged between the punch 6 and the pressing assembly 3;

[0025] The cleaning assembly 4 includes a mounting frame 401. The cleaning assembly 4 can quickly clean the glass slag debris or dust on the surface of the punch. A plurality of springs 403 are evenly distributed in the inner wall of the mounting frame 401. One end of the plurality of springs 403 away from the mounting frame 401 is fixedly installed with a mounting block 404. One end of the mounting block 404 away from the spring 403 is fixedly installed with a cleaning sponge 405. One mounting bracket 402 is fixedly installed on each of the two symmetric outer walls of the mounting frame 401.

[0026] In this embodiment, referring to Figure 1 and Figure 2 shown, the pressing assembly 3 includes a connecting frame 301. Two mounting brackets 402 are symmetrically installed on the outer walls of the two symmetric sides of the connecting frame 301 respectively. At the center of the top of the inner wall of the connecting frame 301, a hydraulic telescopic rod 303 is fixedly installed. The punch 6 is fixedly installed on the telescopic end of the hydraulic telescopic rod 303.

[0027] In this embodiment, referring to Figure 1 and Figure 2 shown, on both sides of the top of the punch 6 near the two mounting frames 401, extrusion blocks 302 are fixedly installed respectively. One side of the two extrusion blocks 302 away from each other is wedge-shaped. The extrusion blocks 302 are used to prevent the relative movement of the mounting blocks 404 from being combined, resulting in the punch not being able to reset upward.

[0028] In this embodiment, referring to Figure 2 and Figure 4 shown, the support assembly 5 includes a support frame 501 and a die 502. One connecting frame 301 is fixedly installed on the outer walls of the two symmetric sides of the support frame 501. A connecting frame 505 is fixedly installed on the inner wall of the die 502. Through holes 503 are symmetrically opened on both sides of the top of the connecting frame 505. A moving frame 504 is clamped in the two through holes 503.

[0029] In this embodiment, referring to Figure 2 and Figure 4 shown, the moving frame 504 is in a "U" shape. Top support blocks 506 are symmetrically opened on the cross bar of the moving frame 504. Top support blocks 506 are fixedly installed above one side of the support frame 501 close to the through hole 503. The top of the top support block 506 contacts the moving frame 504. The top support block 506 is used to support the moving frame 504 to prevent the moving frame 504 from tipping over due to manual pressure.

[0030] In this embodiment, referring to Figure 1 and Figure 2 As shown, a conveying mechanism 2 is provided at the bottom of the inner wall of the heating box 1. The conveying mechanism 2 has the same structure and working principle as the conveying mechanism in a molding device of a utility model patent (Announcement No.: CN209906627U), and will not be described in detail here.

[0031] Working principle: Before use, first power on all electrical equipment in the device, then put the glass to be processed into the conveying mechanism 2 inside the heating box 1 for heating. After heating, it is transmitted to the top of the die 502 by the conveying mechanism 2. At this time, the punch 6 is started. When the punch 6 moves downward, the hydraulic telescopic rod 303 will also descend with the descent of the punch 6, and in the process of descent, the hydraulic telescopic rod 303 will squeeze the spring 403 to slide toward the inside of the mounting frame 401. As the punch 6 descends, the punch 6 will get rid of the contact with the cleaning sponge 405. At this time, the punch 6 will cooperate with the die 502 to pressurize the glass. After completion, the hydraulic telescopic rod 303 drives the punch 6 to move upward, and as the punch 6 moves upward, the extrusion block 302 will also move upward. As the mounting block 404 rises, the cleaning sponge 405 is pushed toward the punch 6 under the action of the spring 403, so as to quickly clean the glass slag or dust on the surface of the punch 6, and avoid the dust falling on the punch 6 when it is on standby.

[0032] When the processing is completed, hold the two through holes 503 with your hands, move the movable frame 504 upward, and move the pressurized glass out, so as to achieve the benefit of quickly removing the glass.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
