Description

Technical Field

[0001] This invention belongs to the field of aerogel product assembly technology, specifically relating to a device for cutting overlapping areas. Background Technology

[0002] Aerogel composites are currently the most effective insulation materials and are widely used in thermal insulation of heating pipe networks and internal insulation layers in aerospace applications. During insulation installation, the aerogel composite material is wrapped around the outer surface of the pipe. To ensure a tight seal at joints, overlaps are often used for connection (e.g., ...). Figure 6 (As shown), however, for materials of a certain thickness, the difference in overlap will create a gap, resulting in an unsatisfactory tightness during actual wrapping. Furthermore, when aerogel materials are used as the inner heat insulation layer of an aircraft, gaps created during assembly can lead to heat leakage, affecting the insulation effect. Therefore, by cutting the overlapping area, the joints can be properly matched and fitted, avoiding gaps (such as...). Figure 7 (As shown). However, currently, the cutting of the aerogel overlapping area is done by workers measuring the dimensions and then cutting out a stepped shape with a hand-held cutter. This method is slow and requires very high skill from the workers, making it easy to produce defective products. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide an apparatus for cutting overlapping areas.

[0004] An apparatus for cutting overlapping areas includes a cutting platform (which is a flat board).

[0005] The tool rail is located on the cutting platform and includes a support frame and a slide bar connected to the support frame;

[0006] The tool holder includes a horizontal metal frame and a vertical metal frame, both of which are rectangular. The horizontal and vertical metal frames are arranged perpendicularly and intersecting each other. The horizontal metal frame is located inside the vertical metal frame, and a fixing member is provided at the connection between the horizontal and vertical metal frames. Both the horizontal and vertical metal frames are equipped with blade supports, and an L-shaped blade is provided between the two blade supports, so that the horizontal metal frame, the vertical metal frame, and the L-shaped blade are combined to form a rectangle. A slider is provided at the top of the horizontal metal frame, and the slider is connected to a slide rod.

[0007] For example, to facilitate clamping the aerogel and make it flat, thereby ensuring smooth cutting and cutting accuracy, a clamping plate is provided on the cutting platform, and a fastening device is provided between the clamping plate and the cutting platform. This fastening device can be bolts.

[0008] For example, to facilitate the adjustment of the blade position to accommodate overlapping areas of different sizes, the blade holder is provided with a blade fixing hole, and an L-shaped blade is placed in the blade fixing hole. One end of the L-shaped blade is the cutting edge, and the other end is the blade back. Several slots are evenly distributed on the blade back of the L-shaped blade, and a locking block that mates with the slot is provided on the blade fixing hole.

[0009] For example, to facilitate the adjustment of the relative positions of the horizontal and vertical metal frames, grooves are provided on both sides of the horizontal and vertical metal frames. The blade holder is provided with connecting rod one and connecting rod two, with one end of connecting rod one and connecting rod two facing each other, and each of the facing ends is provided with a rack. The blade holder is provided with an adjusting rod, and the adjusting rod is provided with a gear that meshes with the rack. By rotating the adjusting rod, the gear rotates, driving the rack to move, so that the other ends of connecting rod one and connecting rod two are inserted into the groove.

[0010] For example, to facilitate the fixing of the horizontal metal frame, the fasteners are a number of fastening screws set on both sides of the vertical metal frame. The two sides of the vertical metal frame are provided with a number of threaded holes with through grooves, and the fastening screws are set in the threaded holes.

[0011] For example, to facilitate the protection of the slider and the slide rod, the support frame includes two support rods, an L-shaped plate between the two support rods, baffles at both ends of the L-shaped plate, and the slide rod between the two baffles; to facilitate the adjustment of the height of the tool holder, the support rods are provided with a sliding groove, the L-shaped plate is placed in the sliding groove, and the support plate is provided with several fasteners for fixing the L-shaped plate.

[0012] The device for cutting overlapping areas according to the present invention has the following advantages compared with the prior art: 1. The present invention can adjust the position of the blade holder according to the overlapping area, and can cut the overlapping area of ​​the required size according to actual needs; 2. The present invention can clamp the material to be cut to ensure the smooth cutting and cutting accuracy, reduce the scrap rate, and save raw materials; 3. The present invention, through the combination of a horizontal metal frame, a vertical metal frame and an L-shaped blade, makes the whole structure stable and simple, and easy to promote and use.

[0029] like Figure 1 As shown, an apparatus for cutting overlapping areas includes a cutting platform 1 (which is a flat board).

[0030] The tool track 2 is located on the cutting platform 1 and includes a support frame 21 and a slide rod 22 connected to the support frame 21. The slide rod 22 is a metal rod.

[0031] Knife holder 3, such as Figure 2 As shown, the tool holder 3 includes a horizontal metal frame 31 and a vertical metal frame 32, both of which are rectangular frames. The horizontal metal frame 31 and the vertical metal frame 32 are arranged perpendicularly to each other. The horizontal metal frame 31 is located inside the vertical metal frame 32. A fixing member is provided at the connection between the horizontal metal frame 31 and the vertical metal frame 32. Both the horizontal metal frame 31 and the vertical metal frame 32 are provided with blade supports 33. An L-shaped blade 34 is provided between the two blade supports 33, so that the horizontal metal frame 31, the vertical metal frame 32 and the L-shaped blade 34 are combined to form a rectangle to ensure the stability of the structure. A slider 321 is provided on the top of the horizontal metal frame 31. The slider 321 has a through hole connected to the slide rod 22, and the slider 321 can slide on the slide rod 22.

[0032] For example, in order to facilitate clamping the aerogel and make it flat, thereby ensuring the smooth cutting and cutting accuracy, the cutting platform 1 is provided with a clamping plate 4, and a fastening device 41 is provided between the clamping plate 4 and the cutting platform 1. The fastening device can be bolts.

[0033] For example, such as Figure 3As shown, to facilitate the adjustment of the blade position to accommodate overlapping areas of different sizes, the blade holder 33 is provided with a blade fixing hole 331. The L-shaped blade 34 is located in the blade fixing hole 331. One end of the L-shaped blade 34 is the cutting edge, and the other end is the back of the blade. Several slots 341 are evenly distributed on the back of the L-shaped blade 34. The blade fixing hole 331 is provided with a locking block 332 that cooperates with the slot 341. When the L-shaped blade 34 is inserted into the blade fixing hole 331, the locking block 332 is locked in the slot 341 to fix the L-shaped blade 34.

[0034] For example, such as Figure 4 As shown, to facilitate the adjustment of the relative positions of the horizontal metal frame 31 and the vertical metal frame 32, grooves 311 are provided on both sides of the horizontal metal frame 31 and the vertical metal frame 32. The blade support 33 is provided with connecting rod 1 333 and connecting rod 2 334. One end of connecting rod 1 333 and connecting rod 2 334 are arranged opposite each other, and each of the opposite ends is provided with a rack. The blade support 33 is provided with an adjusting rod 335. The adjusting rod 335 is provided with a gear that meshes with the rack. By rotating the adjusting rod 335, the gear rotates, driving the rack to move, so that the other ends of connecting rod 1 333 and connecting rod 2 334 are inserted into the grooves 311.

[0035] For example, to facilitate the fixing of the horizontal metal frame, the fasteners are a number of fastening screws 322 set on both sides of the vertical metal frame 32. The vertical metal frame 32 has a number of threaded holes with through grooves 311 on both sides. The fastening screws 322 are set in the threaded holes. By tightening the fastening screws 322 on both sides of the vertical metal frame 32, the horizontal metal frame 31 is fixed.

[0036] For example, such as Figure 5 As shown, to facilitate the protection of slider 321 and slide rod 22, support frame 21 includes two support rods, with an L-shaped plate 211 between the two support rods. Baffles 212 are provided at both ends of the L-shaped plate 211, and slide rod 22 is located between the two baffles 212. To facilitate the adjustment of the height of the tool holder 3, a sliding groove is provided on the support rod, and the L-shaped plate 211 is located in the sliding groove. Several fasteners for fixing the L-shaped plate 211 are provided on the support plate.

[0037] The present invention is achieved in the following way: When in use, the aerogel to be cut is placed on the cutting platform 1 and clamped by the clamping plate 4. The height of the L-shaped blade 34 is determined according to the size of the overlapping area to be cut. That is, the position of the transverse metal frame 31 is adjusted by the fastening screw 322 on the longitudinal metal frame 32, and then the position of the L-shaped blade 34 is adjusted by the blade bracket 33. After adjustment, the L-shaped blade 34 is aligned with the overlapping area to be cut, and then the blade holder 3 is pushed to move along the slide bar 22, thereby cutting the overlapping area into a stepped shape.

[0038] Other aspects of this invention that are not detailed herein are all conventional techniques known to those skilled in the art.

[0039] The scope of protection of this invention is not limited to the technical solutions disclosed in the specific embodiments.
