Description

Technical Field

[0001] This utility model belongs to the field of door sealing sheet metal technology, and in particular relates to a CNC punching machine door sealing sheet metal structure that can be connected to glass. Background Technology

[0002] In modern manufacturing, CNC punch presses, as an important sheet metal processing equipment, are widely used in the processing of various thin metal sheet parts. Through program control, CNC punch presses can efficiently and accurately complete various processing operations such as punching, trimming, and forming, greatly improving the efficiency and quality of sheet metal processing. The sealing door, as an important component of the CNC punch press, not only serves a protective function, preventing operators from accidentally contacting the internal moving parts and avoiding safety accidents, but also helps maintain a stable internal working environment, reducing the impact of external dust and debris on the equipment and extending its service life.

[0003] In practical applications, operators need to observe the processing status inside the CNC punch press in real time to adjust processing parameters and handle abnormal situations promptly. Therefore, installing a glass observation window on the sealing door has become a common design. However, existing connection structures between the sealing door and the glass of CNC punch presses have many problems. Some connection structures are complex to install, requiring significant time and manpower, and installation accuracy is difficult to guarantee, easily leading to insecure glass installation. During punch press operation, vibrations can cause the glass to loosen or fall off, posing safety hazards. Some connection structures have poor sealing performance, failing to effectively prevent dust and moisture from entering the punch press, affecting normal operation and reducing equipment reliability. Furthermore, when the glass needs replacement due to damage, traditional connection structures involve cumbersome disassembly and replacement processes, increasing the difficulty and cost of equipment maintenance and reducing equipment efficiency. In addition, since punch presses generate vibration and noise during operation, some existing connection structures cannot effectively buffer and reduce noise, impacting the operator's working environment and potentially causing long-term damage to the glass and sealing door structure due to vibration.

[0004] Therefore, it is essential to invent a CNC punching machine door sealing sheet metal structure that can be connected to glass. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a CNC punching machine sealing sheet metal structure that can be connected to glass, including a sealing sheet metal body, an insert groove, a clamping plate groove, tempered glass, a pressure plate frame, an inner pressure protrusion, an outer pressure protrusion, a filling area, an injection hole, a sealing bolt, and a fixing bolt. The sealing sheet metal body is provided with an insert groove and a clamping plate groove. The tempered glass is placed in the insert groove of the sealing sheet metal body and is pressed and fixed by the inner pressure protrusion and the outer pressure protrusion provided on the inner surface of the insert groove and the pressure plate frame. The pressure plate frame is fixedly installed in the clamping plate groove by fixing bolts. The filling area is formed between the inner pressure protrusion and the outer pressure protrusion. The injection hole opened in the sealing sheet metal body and the pressure plate frame is connected to the filling area, and each injection hole is threaded with a sealing bolt.

[0006] Preferably, the size of the mounting groove is the same as the size of the tempered glass, and one side edge region of the tempered glass is in close contact with the surfaces of the inner and outer pressure protrusions of the mounting groove, and the other side edge region of the tempered glass is in close contact with the surfaces of the inner and outer pressure protrusions of the inner surface of the pressure plate frame.

[0007] Preferably, the inner and outer pressure protrusions are wrapped with rubber sleeves, both the inner and outer pressure protrusions are rectangular structures, and the filling area formed between them is filled with foamed buffer sealant, which can be injected into the area through the injection hole.

[0008] Preferably, the rectangular strip formed by the curing of the foamed buffer sealant is located on both sides of the tempered glass edge area, and the pressure plate frame is located on the outside of the tempered glass.

[0009] Preferably, the angle formed between the tempered glass and the inner side of the inner pressure convex frame is sealed with adhesive, and a rectangular sealing strip is formed on the inner side of its edge.

[0010] Preferably, the tempered glass is securely installed in the mounting groove by the inner and outer pressure protrusions in conjunction with the pressure plate frame, wherein the edge of the pressure plate frame is fixedly installed in the card slot of the sealing sheet metal body by the fixing bolts.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This utility model features an inlay groove on the sheet metal body of the door seal, with the groove's dimensions matching those of the tempered glass. This allows the tempered glass to be precisely embedded within the groove, ensuring accurate positioning and simple operation during installation. Simultaneously, the pressure plate frame is fixedly mounted in the clamping plate groove using fixing bolts, firmly pressing the tempered glass into the inlay groove. This structural design guarantees the glass's secure installation and effectively prevents loosening or detachment of the glass due to vibration during CNC punching operation, significantly improving the safety of the equipment.

[0012] This invention creates a filling area between the inner and outer pressure convex frames, which is connected to an injection hole. Foamed buffer sealant is injected into the filling area through the injection hole, forming rectangular sealant strips on both sides of the tempered glass. This effectively fills the gap between the glass and the sealing sheet metal, preventing dust and moisture from entering the CNC punch press. This provides excellent protection for the precision components inside the punch press, improving the stability and reliability of the equipment and extending its service life. Furthermore, sealing is applied to the angle formed between the tempered glass and the inner side of the inner pressure convex frame, forming a rectangular sealing strip on its inner edge, further enhancing the sealing effect.

[0013] The inner and outer pressure protrusions of this invention are externally wrapped with rubber sleeves. These rubber sleeves possess excellent elasticity and cushioning properties, effectively buffering vibrations generated during CNC punching operations and reducing rigid collisions between the glass and the door panel, thus preventing damage to the glass due to vibration. Simultaneously, the foamed cushioning sealant within the filling area also has sound-absorbing and noise-reducing functions, effectively reducing the outward transmission of noise generated during punching operations and improving the working environment for operators.

[0014] When tempered glass is damaged and needs to be replaced, this utility model allows you to simply unscrew the fixing bolts, remove the pressure plate frame, and take the damaged glass out of the mounting groove. Then, you can install the new glass by following the reverse steps. The whole process is simple to operate, which greatly reduces the difficulty and cost of equipment maintenance, improves the efficiency of equipment use, reduces downtime caused by equipment maintenance, and provides strong support for the production and operation of enterprises.

Those skilled in the art can understand the specific meaning of the above terms in the present utility model based on the specific circumstances.

[0021] As attached Figure 1 To be continued Figure 3 As shown: This utility model provides a CNC punching machine sealing sheet metal structure that can be connected to glass, including a sealing sheet metal body 1, an inlay groove 2, a clamping plate groove 3, tempered glass 4, a pressure plate frame 5, an inner pressure protrusion 6, an outer pressure protrusion 7, a filling area 8, an injection hole 9, a sealing bolt 10, and a fixing bolt 11. The sealing sheet metal body 1 is provided with an inlay groove 2 and a clamping plate groove 3. The tempered glass 4 is disposed in the inlay groove 2 of the sealing sheet metal body 1 and is pressed and fixed by the inner pressure protrusion 6 and the outer pressure protrusion 7 provided on the inner surface of the inlay groove 2 and the pressure plate frame 5. The pressure plate frame 5 is fixedly installed in the clamping plate groove 3 by the fixing bolt 11. The filling area 8 is formed between the inner pressure protrusion 6 and the outer pressure protrusion 7. The injection hole 9 opened in the sealing sheet metal body 1 and the pressure plate frame 5 is connected to the filling area 8, and each injection hole 9 is threaded with a sealing bolt 10.

[0022] Furthermore, the mounting groove 2 is made of cold-rolled steel sheet by stamping, and its overall dimensions are perfectly matched with the 8mm thick tempered glass 4, ensuring that the tempered glass 4 can be accurately embedded. The edge area of ​​one side of the tempered glass 4 (width 10-40mm) is fully and tightly fitted with the surfaces of the inner pressure protrusion frame 6 (aluminum alloy material, with a right-angled protrusion cross-section) and the outer pressure protrusion frame 7 (same material, set parallel to the inner pressure protrusion frame 6) integrally formed on the inner side of the mounting groove 2, with the flatness error of the fitting surface controlled within 0.5mm; while the edge area of ​​the other side of the tempered glass 4 is also in close contact with the surfaces of the inner pressure protrusion frame 6 and the outer pressure protrusion frame 7 welded to the inner surface of the pressure plate frame 5 (galvanized steel sheet bending part). The protrusion frames on both sides form an initial clamping of the edge of the tempered glass 4, laying the foundation for subsequent fixation.

[0023] Furthermore, both the inner pressure protrusion 6 and the outer pressure protrusion 7 are wrapped with a 2mm thick EPDM rubber sleeve (which has excellent weather resistance and elasticity). Both are rectangular frame structures that match the edge of the tempered glass 4. The height of the protrusions of the inner pressure protrusion 6 and the outer pressure protrusion 7 is between 2-5mm, forming a 6mm wide filling area 8 between them. The foamed buffer sealant filling this filling area 8 is a one-component polyurethane foam, which is injected through a 4mm diameter injection hole 9 in the middle of the outer pressure protrusion 7. The rubber sleeve can prevent the foam from directly contacting the metal protrusion and enhance the flexible fit with the edge of the tempered glass 4. There is an injection hole 9 at each of the four corners of the filling area 8.

[0024] Furthermore, the foamed buffer sealant injected through injection hole 9 cures within the filling area 8, forming a rectangular strip with the same dimensions as the filling area 8. This strip is located on both sides of the tempered glass 4 edge area (5mm from the glass edge), providing 360° wrapping buffer for the glass edge. The pressure plate frame 5 (20mm wide) is made of Q235 steel plate and is located entirely on the outside of the tempered glass 4, corresponding to the mounting groove 2. It applies stable pressure to the tempered glass 4 from the outside through its own rigidity.

[0025] Furthermore, at the 90° angle formed between the inner edge of the tempered glass 4 and the inner side of the inner pressure frame 6, neutral silicone weather-resistant sealant is applied for sealing. The sealant width is 3mm and the thickness is 2mm. After curing, a continuous rectangular sealant strip is formed at this angle. This sealant strip, together with the foamed buffer sealant, forms a dual sealing system, which can effectively prevent moisture and dust from entering the interior of the structure, while enhancing the tightness of the connection between the tempered glass 4 and the inner pressure frame 6.

[0026] Furthermore, the position of the tempered glass 4 within the mounting groove 2 is jointly restricted by the inner pressure protrusion 6, the outer pressure protrusion 7, and the pressure plate frame 5. The inner pressure protrusion 6 fits against the inner edge of the glass, the outer pressure protrusion 7 fits against the outer edge of the glass, and the pressure plate frame 5 presses against the outer pressure protrusion 7 with its own plane. The three work together to form a fixed structure of "inner positioning + outer pressing" to ensure that the tempered glass 4 does not loosen or shift. Among them, the edge of the pressure plate frame 5 is machined with bolt holes with a diameter of 7mm, which correspond to the card slots 3 (12mm deep, 15mm wide) on the sealing sheet metal body 1 (1.5mm thick cold-rolled steel plate). M6 stainless steel fixing bolts 11 (evenly distributed at 180mm intervals) pass through the bolt holes and are tightened onto the nut seats in the card slots 3, realizing a firm connection between the pressure plate frame 5 and the sealing sheet metal body 1.

[0027] The working principle is as follows: First, the tempered glass 4 is embedded in the pre-set mounting groove 2 of the sealing sheet metal body 1. The inner pressure protrusion 6 and the outer pressure protrusion 7 on the inner wall of the mounting groove 2 form a preliminary positioning and fit on one side edge of the tempered glass 4.

[0028] Next, the pressure plate frame 5 is placed over the other side of the tempered glass 4, so that the inner pressure protrusion 6 and the outer pressure protrusion 7 on the inner side of the pressure plate frame 5 are in close contact with the edge of the tempered glass 4, and cooperate with the protrusion of the mounting groove 2 to form a bidirectional clamping of the glass.

[0029] Subsequently, the edge of the pressure plate frame 5 is fastened to the slot 3 of the sealing sheet metal body 1 by fixing bolts 11. With the help of the pre-tightening force of the bolts, the inner pressure protrusion 6, the outer pressure protrusion 7 and the pressure plate frame 5 work together to firmly restrict the tempered glass 4 in the mounting groove 2, thus completing the assembly and fixation of the overall structure.

[0030] At the same time, foamed buffer sealant is injected into the filling area 8 between the inner and outer pressure protrusions 6 and 7 through the injection hole 9 on the sealing sheet metal body 1 and the pressure plate frame 5. After the sealant cures to form a rectangular strip, it achieves flexible wrapping and buffer sealing of the glass edge. Then, the injection hole 9 is sealed with the sealing bolt 10.

[0031] Finally, sealant is applied at the angle between the tempered glass 4 and the inner side of the inner pressure convex frame 6 to form a rectangular sealing strip, which together with the foam adhesive forms a double sealing system to block external moisture and dust.

[0032] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
