Description

Technical Field

[0001] This invention relates to the field of A2 sheet metal forming technology, specifically a double-track pressing device for forming A2 sheet metal. Background Technology

[0002] Currently, the traditional tracked pressing and forming equipment used in the hot pressing and forming process of A2 three-layer composite panels has many technical defects and is difficult to meet the production and processing needs of high-efficiency, multi-specification panels.

[0003] First, the forming limiting structure of traditional forming equipment is mostly a fixed structure, which cannot flexibly adjust the limiting size according to A2 plates of different thicknesses and widths. The equipment can only be adapted to the processing of a single specification of plate, with poor versatility and severely limited adaptability.

[0004] Secondly, the insertion equipment lacks an effective side sealing and limiting structure. When the board is hot-pressed at high temperature, the internal filling material is very easy to expand and overflow due to heat. This not only wastes raw materials, but also causes the board edges to be defective and the thickness to be uneven, which seriously affects the board forming quality.

[0005] In addition, the traditional equipment has a simple contact structure between the track and the sheet metal, with a small contact area. The sheet metal is prone to slippage and deviation during transportation, resulting in a discontinuous forming process. Furthermore, the inlet and outlet openings of the forming chamber are large and there is no professional temperature-locking and sealing structure. As a result, the equipment loses a lot of heat during operation, which not only leads to high energy consumption but also causes large temperature fluctuations inside the forming chamber. This results in uneven heating of different areas of the sheet metal, causing problems such as forming deformation and inconsistent quality.

[0006] Based on this, the present invention provides a dual-track pressing device for forming A2 sheet metal to solve the above problems. Summary of the Invention

[0007] In view of the above situation and to overcome the defects of the prior art, the present invention provides a double-track pressing device for A2 sheet forming. The present invention has an ingenious structure and focuses on practicality, effectively solving the technical problems of difficulty in achieving high efficiency, limited adaptability and inability to guarantee the quality of sheet forming.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A dual-track pressing device for forming A2 sheet metal includes a lower drive track, an upper drive track, and a forming chamber. The upper drive track is slidably connected above the lower drive track. A clamping frame is fixedly installed inside the forming chamber. A limiting plate is provided between the clamping frames and placed between the lower drive track and the upper drive track. A hot air fan is fixedly installed above the lower drive track and the upper drive track, with a portion placed inside the forming chamber.

[0010] Preferably, there are two clamping frames. Each clamping frame is composed of a fixed frame, two sets of adjusting nuts, and two sets of clamping frames. There are two adjusting nuts and two clamping frames in each set. The adjusting nuts are connected to the clamping frames and are threaded onto the clamping frames.

[0011] Preferably, a plurality of upper track supports are fixedly installed in the molding chamber, and a support adjustment frame fixedly installed on the upper drive track is provided above the upper track supports.

[0012] Preferably, each of the support adjustment frames is provided with a locking nut, which can provide stable support for the adjusted support adjustment frame.

[0013] Preferably, both the lower and upper drive tracks are provided with multiple evenly distributed membrane drive frames on their surfaces.

[0014] Preferably, the surface of the molding chamber has two symmetrically distributed plate inlets and outlets.

[0015] Preferably, the lower drive track is one of the following specifications: 36M, 30M, 24M, 18M, or 12M.

[0016] Preferably, the upper drive track is a 24M track.

[0017] The present invention has the following technical advantages.

[0018] 1. This invention uses an adjustable clamping frame combined with a limiting plate to adapt and fix limiting plates of different sizes by adjusting the spacing of the clamping frame, which can meet the forming and processing needs of A2 plates of different thicknesses and widths, and has a wider range of applications.

[0019] 2. This invention relies on a limiting plate to seal and limit the forming area of ​​the board on both sides, which can effectively prevent the filling material from overflowing due to thermal expansion during the heating process, avoid problems such as edge defects and material shortages, ensure the integrity of the board forming, and reduce raw material loss.

[0020] 3. This invention uses a membrane transmission frame with a transverse plate structure evenly distributed on the surface of the upper and lower transmission tracks to increase the effective contact area between the tracks and the sheet metal, improve the fit and friction during sheet metal conveying, and eliminate problems such as slippage, deviation, and misalignment during sheet metal conveying. This ensures that the sheet metal hot pressing process is continuous, stable, and orderly. The forming chamber is equipped with a narrow slit-type inlet and outlet that only allows the sheet metal to pass through, and is equipped with a flexible heat-insulating sealing strip to seal gaps to the greatest extent, reduce internal heat loss, and achieve efficient temperature locking.

[0026] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 2 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0027] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0028] This invention relates to a dual-track pressing device for forming A2 sheet metal, comprising a lower drive track 1, an upper drive track 2, and a forming chamber 14. The upper drive track 2 is slidably connected above the lower drive track 1. The lower drive track 1 is equipped with a separate frequency converter drive. The control system is rigidly synchronized with the upper drive track 2, matching their linear speeds in real time and compensating for speed differences in real time. This prevents stretching of the upper soft surface layer and dragging and misalignment of the lower substrate, ensuring the alignment of the three-layer composite structure without deviation. A clamping frame 13 is fixedly installed inside the forming chamber 14, and a limiting plate 1 is provided between the clamping frames 13 and positioned between the lower drive track 1 and the upper drive track 2. 2. The clamping frame 13 is used to fix the limiting plates 12 of different sizes by adjusting the spacing, so as to perform side limiting and auxiliary forming of A2 plates of different thicknesses, and prevent the filling material from overflowing due to heating expansion. The hot air fan 8 is fixedly installed above the lower transmission track 1 and the upper transmission track 2, which is placed inside the forming chamber 14. The forming chamber 14 is provided with a heating forming frame 5. The heating forming frame 5 is fixedly installed with a placement platform 6 and a hot air fan 8. The hot air fan 8 is a combination of a hot air fan and an air outlet, and the air outlet of the hot air fan 8 is placed inside the forming chamber 14. A protective ladder 9 is fixedly installed on one side of the heating forming frame 5.

[0029] In this embodiment, before hot pressing the three-layer composite A2 sheet, the height of the upper drive track 2 can be adjusted according to the actual thickness of the sheet product, the distance between the lower drive track 1 and the upper drive track 2 can be changed, and a suitable width of the limiting plate 12 can be selected. Then, the limiting plate 12 is fixed and limited by adjusting the clamping frame 13. The limiting plate 12 is used to block and limit the two sides of the lower drive track 1 and the upper drive track 2. Finally, the sheet between the lower drive track 1, the upper drive track 2 and the limiting plate 12 is subjected to stable heating and extrusion molding by the hot air blower 8.

[0030] As an example, there are two clamping frames 13. Each clamping frame 13 is composed of a fixed frame, two sets of adjusting nuts, and two sets of clamping frames. There are two sets of adjusting nuts and two sets of clamping frames. The adjusting nuts are connected to the clamping frames and are threaded onto the clamping frame 13.

[0031] In this embodiment, when the clamping frame 13 is adjusted according to the thickness of the sheet material, the adjusting nut can be turned directly to move the clamping frame, thereby adjusting the distance between the clamping frames. By adjusting the distance between the clamping frames, the limiting plates 12 of different specifications are clamped and fixed, and the fixed limiting plates 12 are used to provide side limiting protection for the forming of the sheet material.

[0032] As an example, multiple upper track supports 3 are fixedly installed inside the molding chamber 14. Each upper track support 3 is composed of multiple bolts and steel plates. Above the upper track supports 3, a support adjustment frame 4 is fixedly installed on the upper transmission track 2. The support adjustment frame 4 is a structure composed of a lower fixed steel cylinder, a threaded screw, and an upper threaded sleeve. The upper threaded sleeve is rotatably connected to both sides of the upper transmission track 2 through bearings. The lower fixed steel cylinder and the threaded screw are integrally welded together, and the threaded screw and the upper threaded sleeve are threadedly connected. Each support adjustment frame 4 is provided with a locking nut 10. The locking nut 10 is threadedly connected to the surface of the threaded screw and is positioned below the upper threaded sleeve. The locking nut 10 can provide stable support for the adjusted support adjustment frame 4.

[0033] In this embodiment, when the height of the upper drive track 2 is actually adjusted, the upper drive track 2 can be raised and lowered by rotating the upper threaded sleeve on the support adjustment frame 4, thereby adjusting the distance between the lower drive track 1 and the upper drive track 2. After the height of the upper threaded sleeve is adjusted, the upper threaded sleeve is double-locked and supported by the locking nut 10 to ensure the stability of the upper drive track 2 after the height is adjusted.

[0034] As an example, both the lower drive track 1 and the upper drive track 2 are provided with multiple evenly distributed membrane drive frames 7. The membrane drive frames 7 are horizontal plate structures, which can fully contact the plates and ensure transmission stability.

[0035] As an example, the surface of the molding chamber 14 has two symmetrically distributed plate inlets and outlets 15. The track inlets and outlets 15 are reserved with only narrow gaps just wide enough for the plates to pass through. The gaps are equipped with flexible heat-insulating sealing strips to lock in the temperature to the maximum extent.

[0036] As an example, the lower drive track 1 is one of the track specifications of 36M, 30M, 24M, 18M, and 12M.

[0037] As an example, the upper drive track 2 is a 24M track.

[0038] Working principle:

[0039] S1. First, according to the actual thickness specifications of the three-layer composite A2 plate to be processed, the upper transmission track 2 is driven to complete the height adjustment by rotating the upper threaded sleeve of the support adjustment frame 4, and the forming gap between the lower transmission track 1 and the upper transmission track 2 is precisely adjusted. After the gap is adjusted, the upper threaded sleeve is locked and fixed by the locking nut 10 on the threaded screw to ensure the structural stability of the upper transmission track 2 after adjustment.

[0040] S2. Then, select a suitable limiting plate 12 according to the width of the plate, rotate the adjusting nuts of the two sets of clamping frames 13 to drive the clamping frame to move, adjust the clamping frame spacing to firmly clamp and fix the limiting plate 12, so that the limiting plate 12 blocks the upper and lower transmission tracks on both sides, and realizes the side limiting protection during the plate forming process.

[0041] S3. After completing the mechanical structure adjustment, start the equipment. The lower transmission track 1 is equipped with an independent frequency conversion drive system and forms a hard synchronous linkage control with the upper transmission track 2. The linear speed of the two is matched in real time and the speed difference is dynamically compensated to prevent the misalignment of the plates caused by the deviation of the track transmission speed.

[0042] S4. Finally, turn on the hot air blower 8 inside and above the molding chamber 14. The hot air is evenly introduced into the molding chamber 14 through the air outlet to evenly heat the plate clamped between the upper and lower transmission tracks. With the stable conveying and pressing action of the double tracks, the A2 plate is accurately and stably hot-pressed. At the same time, the narrow gap and flexible heat insulation sealing strip of the plate inlet and outlet 15 of the molding chamber 14 can effectively lock in the internal temperature and ensure the stable temperature of the molding environment for continuous molding process.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
