Description

Technical Field

[0001] This utility model relates to the field of special glass processing tooling technology, and in particular to a tooling for removing the anti-splash layer from rail transit glass. Background Technology

[0002] Currently, rail transit glass, especially high-speed train glass, typically has an anti-splash layer on the inside to protect the driver and passengers in the event of an impact. Specifically, this is achieved by laminating an anti-splash film (PET film) onto the inner glass surface using PVB film, followed by high-temperature and high-pressure treatment in an autoclave. However, during the production or use of glass with this anti-splash layer, defects such as poor appearance and air bubbles in the PVB film can occur. In these cases, the anti-splash layer needs to be removed from the glass for re-lamination. Removing the anti-splash layer from the inner glass under high temperature and pressure is not easy, and ordinary safety blades cannot be used due to the relatively large size of the glass. However, leaving it on will render the glass unusable. Therefore, there is an urgent need for a tooling system to remove the defective anti-splash layer from rail transit glass. Utility Model Content

[0003] The purpose of this invention is to provide a tooling for removing the anti-splash layer from rail transit glass. This tooling facilitates the removal of defective anti-splash layers during production or use, resulting in a quick, clean process that promotes glass re-lamination and improves the glass's pass rate.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A tool for removing the anti-splash layer from rail transit glass includes a rear hand-held part, one end of which is connected to a front mounting part, and the other end of the front mounting part is connected to a safety blade. The safety blade is arranged along the length direction perpendicular to the rear hand-held part. The front mounting part is also provided with a through observation hole to observe the removal of the anti-splash layer by the safety blade.

[0006] By adopting the above technical solution, the rear handheld part is convenient for operators to hold and use, and the front-end mounting part is a safety blade, which facilitates the removal of defective anti-splash layer during production or use. The removal of the anti-splash layer by the safety blade can be observed through the observation hole, which is beneficial for glass re-lamination and thus improves the glass qualification rate.

[0007] Furthermore, the safety blade is detachably connected to the front mounting component.

[0008] By adopting the above technical solution, it is convenient to replace the blade in a timely manner when it is found to be dull or nicked.

[0009] Furthermore, the front-end mounting component includes two mounting plates, with an observation hole located at the same position on both metal plates, and a safety blade clamped between the two mounting plates.

[0010] By adopting the above technical solution, the safety blade is clamped by two mounting plates, making it convenient to replace and use.

[0011] Furthermore, the mounting plate includes a front clamping plate and a rear limiting plate. The front clamping plate is connected to the outer end of the rear limiting plate, and the distance between the two front clamping plates is smaller than the distance between the two rear limiting plates. The safety blade includes a blade edge side and a clamping side. The clamping side is thicker than the blade edge side. The clamping side is installed between the two rear limiting plates, while the blade edge side is clamped between the two front clamping plates.

[0012] By adopting the above technical solution, the front clamping plate and the rear limiting plate form a groove. The groove is designed according to the size of the safety blade, which makes it easy to disassemble and install the safety blade.

[0013] Furthermore, the distance between the two rear limit plates is not less than the thickness of the clamping side, and the distance between the two front clamping plates is not greater than the thickness of the blade side.

[0014] By adopting the above technical solution, the front clamping plate can clamp the blade side, while the rear limiting plate restricts the movement of the clamping side.

[0015] Furthermore, the mounting plate is a metal plate.

[0016] By adopting the above technical solution, the mounting plate has a certain degree of flexibility, making it convenient to install and use.

[0017] Furthermore, the inner end of the mounting plate is connected to the rear handheld part.

[0018] By adopting the above technical solution, the connection between the mounting plate and the rear handheld part is achieved.

[0019] Furthermore, the length direction of the observation hole is perpendicular to the safety blade.

[0020] By adopting the above technical solution, it is convenient to observe the removal of the anti-splash layer by the safety blade along a line perpendicular to the safety blade.

[0021] Furthermore, the maximum width of the front-end mounting component is less than twice the minimum width of the rear-end handheld part near the front-end mounting component.

[0022] By adopting the above technical solution, the cleaning effect of the safety blade is guaranteed, and the observation hole facilitates observation.

[0023] Furthermore, the rear handheld part has a through-hole for suspension.

[0024] By adopting the above technical solution, the suspension hole opened in the rear handheld part facilitates the use of rear suspension.

[0025] In summary, the present invention has the following beneficial effects:

[0026] The rear handheld part is convenient for operators to hold and use, while the front mounting piece is a safety blade, which facilitates the removal of defective anti-splash layers during production or use. A rear limiting plate and a front clamping plate are also included, allowing the front clamping plate to hold the blade edge while the rear limiting plate restricts movement of the clamping side, thus facilitating the installation and use of the safety blade. During the removal of defective anti-splash layers, the maximum width of the front mounting piece is limited, allowing for easy application of force while also enabling direct observation of the safety blade's removal of the anti-splash layer through the inspection hole. This facilitates glass re-lamination and improves the glass's yield rate. Attached Figure Description

Detailed Implementation

[0032] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation on this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0033] A tool for removing the splash guard from rail transit glass, such as Figure 1As shown, the corresponding rail transit glass includes, from the outside to the inside, an outer glass layer 01, a PVB inspection layer 02, an inner glass layer 03, and a splash guard layer 04. The tooling in this embodiment is used to remove the defective splash guard layer 04 from the rail transit glass.

[0034] like Figure 2 and Figure 3 As shown, the tooling in this embodiment includes a rear hand-held part 1, one end of which is connected to a front mounting part 2, and the other end of the front mounting part 2 is used to connect a safety blade 3. The safety blade 3 is arranged along the length direction perpendicular to the rear hand-held part 1 to achieve the removal of the anti-splash layer 04.

[0035] In this embodiment, in order to facilitate applying force to the front safety blade 3 and better remove the splash guard, the maximum width of the front mounting part 2 is less than twice the minimum width of the rear handheld part 1 near the front mounting part 2. In this embodiment, the maximum width of the front mounting part 2 is 1.4 times the minimum width of the rear handheld part 1 near the front mounting part 2.

[0036] like Figure 3 As shown, the safety blade 3 is detachably connected to the front mounting component 2. The front mounting component 2 includes two symmetrically arranged mounting plates 21. The inner ends of the mounting plates 21 are connected to the rear handheld part 1 by means of embedding or welding. The safety blade 3 is clamped between the two mounting plates 21.

[0037] Specifically, the mounting plate 21 includes a front clamping plate 211 and a rear limiting plate 212. The front clamping plate 211 is connected to the outer end of the rear limiting plate 212, and the distance between the two front clamping plates 211 is smaller than the distance between the two rear limiting plates 212, so that the rear limiting plate 212 and the front clamping plate 211 and the front mounting part 2 at the front and rear positions form a limiting groove-shaped space.

[0038] like Figure 4 As shown, the safety blade 3 includes a blade side 31 and a clamping side 32. The clamping side 32 is thicker than the blade side 31 (in this embodiment, the clamping side 32 is U-shaped, with the open side fitted onto the non-sharp side of the blade side 31, and fixed together by means of bonding, screw connection, welding or interference fit, etc.). The clamping side 32 is installed between the two rear end limiting plates 212 (located in the space of its limiting groove), while the blade side 31 is clamped between the two front end clamping plates 211; and the distance between the two rear end limiting plates 212 is not less than the thickness of the clamping side 32, and the distance between the two front end clamping plates 211 is not greater than the thickness of the blade side 31.

[0039] To facilitate the installation of the safety blade 3, the mounting plate 21 is made of metal, giving it a certain degree of elasticity, which allows the front clamping plate 211 to clamp the blade side 31, while the rear limiting plate 212 restricts the movement of the clamping side 32.

[0040] like Figure 2 As shown, the front mounting part 2 is also provided with a through observation hole 22. The observation hole 22 is located at the same position on the two metal plates so as to observe the removal of the anti-splash layer 04 by the safety blade 3 through the observation hole 22. In this embodiment, the length direction of the observation hole 22 is perpendicular to the safety blade 3. The rear handheld part 1 is also provided with a through hanging hole 11 for hanging, which is convenient for hanging.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
