Description

Technical Field

[0001] This utility model relates to the field of irregular pipe fitting production technology, and in particular to a thin film peeler for irregular pipe fitting surface. Background Technology

[0002] Internal high-pressure forming is an advanced manufacturing technology that uses a liquid medium to apply high pressure inside a closed pipe, causing the material to plastically deform and fit into the mold. The pipes used in automobile chassis are usually variable cross-section irregular pipes. The internal high-pressure forming process is often used in the production of these irregular pipes. In order to reduce the friction between the irregular pipe and the inner wall of the mold during internal high-pressure forming, a thin film is usually put on the outer wall of the pipe to make the material flow better during forming. After forming, the thin film on the outer wall of the irregular pipe needs to be peeled off.

[0003] Traditionally, the method of peeling off the membrane from pipes is manual. For irregularly shaped pipes with variable cross-sections, manual peeling of the surface membrane is usually complicated and inconvenient, and the peeling process is difficult, resulting in low peeling efficiency.

[0004] Based on this, those skilled in the art have proposed a thin film peeler for irregularly shaped pipes, providing a new solution to the aforementioned technical problems. Utility Model Content

[0005] Therefore, it is necessary to provide a thin film peeler for the surface of irregularly shaped pipes to address the problems raised in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] The aforementioned non-circular pipe surface film peeler specifically includes a handle, with the pipe film attached to the outer wall of the handle, and a collar that can be sleeved on the outside of the handle. A peeling airbag for peeling the pipe film is fixed inside the collar, and an air compressor for providing an air source is also included. The output end of the air compressor is connected to a proportional valve through an air pipe. The proportional valve is used to adjust the inflation pressure, and the output end of the proportional valve is connected to the peeling airbag through an air pipe.

[0008] Preferably, the inner diameter of the release airbag varies with the air pressure inside it.

[0009] Preferably, the upper and lower end faces of the peeling airbag are configured as connecting surfaces, which are respectively connected to the upper and lower inner walls of the collar.

[0010] Preferably, the upper and lower end faces of the peeling airbag are provided with a plurality of connection points, and the peeling airbag is connected to the upper and lower inner walls of the collar through the plurality of connection points.

[0011] Preferably, the connection points on the upper and lower end faces of the peeling airbag correspond one-to-one, and each set of corresponding connection points is located in the same vertical direction.

[0012] Preferably, when the internal air pressure of the peeling airbag increases, an indentation is formed inward at the corresponding connection points located above and below.

[0013] Preferably, handles are fixed on both sides of the collar.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model uses an inflatable peeling airbag to remove the thin film from the pipe surface by utilizing the principle of elastic expansion or contraction of the peeling airbag under different pressures. This can better adapt to the peeling of thin films on pipe walls with variable cross-sections, thus improving practicality, adaptability and production efficiency.

[0016] 2. This utility model peels off the membrane from the pipe wall by peeling off the airbag tightly attached to the pipe membrane. For pipe fittings with little change in cross-sectional area, the inflation pressure can be set directly. For pipe fittings with large change in cross-sectional area, the inflation pressure can be adjusted by a proportional valve, which facilitates manual operation, improves production efficiency, and enhances adaptability.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-9 The present invention provides a special-shaped pipe surface film peeler, including a handle 5, a pipe membrane attached to the outer wall of the handle 5, a collar 3 that can be sleeved on the outside of the handle 5, a peeling airbag 4 for peeling the pipe membrane fixed inside the collar 3, and an air compressor 1 for providing air source. The output end of the air compressor 1 is connected to a proportional valve 2 through an air pipe. The proportional valve 2 is used to adjust the inflation pressure. The output end of the proportional valve 2 is connected to the peeling airbag 4 through an air pipe. The peeling airbag 4 is inflatable and can elastically expand or shrink under different inflation pressures. When the peeling airbag 4 is inflated, it is tightly attached to the pipe membrane. When in use, the operator sleeves the peeling airbag 4 on the outside of the pipe and positions it outside the end of the pipe membrane. Then, the air pressure inside the peeling airbag 4 is increased to press the end of the pipe membrane. Then, the peeling airbag 4 is moved along the axis of the pipe to remove the pipe membrane using this principle.

[0031] For cases where the cross-sectional area changes little, the inflation pressure can be set directly. For cases where the cross-sectional area changes significantly, a proportional valve 2 can be installed between the air compressor 1 and the stripping airbag 4 and connected through an air pipe. The inflation pressure can be adjusted by adjusting the proportional valve 2 to regulate the internal air pressure of the stripping airbag 4, thereby facilitating manual operation, improving production efficiency, and enhancing adaptability.

[0032] Please refer to Figure 1-9The material of the release airbag 4 is set to be a soft and elastic material, such as rubber, soft plastic, aluminum film latex, etc., so that the inner diameter of the release airbag 4 changes with the change of its internal air pressure.

[0033] Please refer to Figure 3-6 The upper and lower ends of the peeling airbag 4 are set as connecting surfaces and are connected to the upper and lower inner walls of the collar 3 respectively. When in use, the upper and lower ends of the peeling airbag 4 can be glued to the upper and lower inner walls of the collar 3. When the air pressure inside the peeling airbag 4 increases, its inner wall expands outward completely and adheres to the outside of the duct membrane to form a full wrap.

[0034] Please refer to Figure 7-8 The upper and lower end faces of the peeling airbag 4 are provided with several connection points 41. The peeling airbag 4 is connected to the upper and lower inner walls of the collar 3 through several connection points 41. The connection points 41 on the upper and lower end faces of the peeling airbag 4 correspond one-to-one, and each set of corresponding connection points 41 are located in the same vertical direction. When the internal air pressure of the peeling airbag 4 increases, the corresponding connection points 41 form an inward depression. When the peeling airbag 4 is fixedly connected to the collar 3 through the connection points 41, when the internal air pressure increases, the part located at the connection point 41 does not expand outward due to the action of the connection point 41, while the remaining part expands outward under the action of air pressure, so that the connection point 41 forms an inward depression relative to the other expanded part. This depression position forms a gap between the peeling airbag 4 and the pipeline membrane when the peeling airbag 4 peels off the pipeline membrane, thereby avoiding the situation where the movement is difficult due to excessive friction between the peeling airbag 4 and the pipeline.

[0035] Please refer to Figure 9 Handles 5 are fixed on both sides of the collar 3. The handles 5 provide a point of leverage for the workers' hands when moving the collar 3 along the pipeline, making it easier for the workers to operate.

[0036] The specific working principle of the surface film peeler for irregularly shaped pipes provided by this utility model is as follows:

[0037] During use, the operator attaches the peeling airbag 4 to the outside of the pipe and positions it outside the end of the pipe membrane. Then, the operator adjusts the air pressure inside the peeling airbag 4 through the proportional valve 2 to press down on the end of the pipe membrane. Subsequently, the peeling airbag 4 is moved along the axis of the pipe to peel the pipe membrane off from the outside of the pipe.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
