Description

Technical Field

[0001] This utility model relates to the field of fabric-reinforced phenolic pipe technology, and in particular to a protective device for the production of fabric-reinforced phenolic pipes. Background Technology

[0002] Phenolic resin-reinforced fabric pipes, made of phenolic resin as the matrix and fabric as the reinforcing material, are widely used in automotive manufacturing, aerospace, and electronics industries due to their excellent mechanical strength, heat resistance, and electrical insulation properties. In the production and processing of phenolic resin-reinforced fabric pipes, cutting is a crucial step to ensure the pipes reach the specified length and meet subsequent assembly requirements.

[0003] Phenolic resin-reinforced pipes are made of resin and fabric composites. During cutting, they easily generate a mixture of phenolic resin debris and fabric fibers. Existing cutting equipment often lacks a specific protective structure. The debris flies everywhere as the cutting blade rotates at high speed, not only polluting the workshop air and increasing the risk of inhalation for operators, but also easily adhering to the surface of the equipment's transmission components, causing wear, reduced transmission accuracy, and shortening the equipment's service life. Furthermore, after cutting phenolic resin-reinforced pipes, the cut edges are prone to defects such as burrs and fiber lifting. Existing equipment requires additional manual or separate grinding treatment, which is inconvenient. Therefore, a protective device for the production of phenolic resin-reinforced pipes is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective device for the production of fabric-reinforced phenolic resin pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A protective device for the production of phenolic resin-reinforced pipes includes a workbench and a bidirectional motor. A support frame is installed on the workbench, and a telescopic cylinder is installed on the support frame. A lifting plate is provided on one end of the telescopic cylinder. A cutting blade is rotatably connected inside the lifting plate. A protective shell is also connected to the bottom side of the lifting plate. A gas-water mixing spray strip is installed on the outside of the protective shell. A base is also provided on the workbench, and outer collection boxes are installed on both sides of the base.

[0006] Preferably, there are two support frames, which are symmetrically installed on both sides of the workbench. Each support frame is equipped with a telescopic cylinder on its top surface. The telescopic ends of the telescopic cylinders are movably connected to the bottom side of the support frame, and the telescopic ends of the two telescopic cylinders are connected to both ends of the lifting plate.

[0007] Preferably, the middle position of the lifting frame is in the shape of an "n", and two horizontal frames are symmetrically installed on the bottom side of the lifting frame. A drive shaft is rotatably connected between the horizontal frames. The cutting blade is installed on the outer surface of the drive shaft. Synchronous rotating drive belts are connected to the output ends on both sides of the bidirectional motor. The other ends of the two synchronous rotating drive belts are respectively connected to the two sides of the drive shaft.

[0008] Preferably, a transparent protective plate is vertically installed between the horizontal frame and the lifting frame plate, the synchronous rotation drive belt is located outside the protective plate, the cutting blade is located between the protective plates, and grinding blocks are fixedly installed on both ends of the drive shaft.

[0009] Preferably, two connecting rods are symmetrically installed on the bottom surface of the protective shell. The connecting rods are movably connected to both ends of the lifting frame plate. A compression spring is provided on the outer surface of the connecting rod. The compression spring is located between the lifting frame plate and the protective shell. A connecting groove is provided in the middle of the bottom surface of the protective shell.

[0010] Preferably, a "V"-shaped through groove is provided at the middle position of the bottom side of the protective shell and the middle position of the top side of the base.

A soda-water mixing spray strip is symmetrically installed on both sides of the protective shell. The outer collection box is located at the bottom side of the soda-water mixing spray strip.

[0011] The beneficial effects of this utility model are: This solution completely covers the cutting area with a protective shell, reducing the possibility of debris during the cutting process. The bidirectional motor drives the rotation of the cutting blade and grinding block to achieve the effect of cutting and grinding the pipe. The movable block can clamp materials of different sizes and block debris from splashing out over a large area. The air-water mixed spray strip can further prevent debris from spreading out.

[0012] This solution reduces the possibility of debris flying everywhere during the cutting of material pipes, reduces the possibility of secondary grinding required for defects such as burrs and fiber lifting at the cut ends of the material after cutting, improves the debris protection effect of the device during the cutting process, reduces the possibility of polluting the workshop air and causing operators to inhale it, and also improves the grinding effect of the device, saving a lot of working time by allowing grinding after cutting.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example: Refer to Figure 1-4 A protective device for the production of phenolic resin-reinforced pipes includes a workbench 1 and a bidirectional motor 6. A support frame 2 is installed on the workbench 1, and a telescopic cylinder 3 is installed on the support frame 2. A lifting plate 7 is provided on one end of the telescopic cylinder 3. A cutting blade 4 is rotatably connected inside the lifting plate 7. A protective shell 8 is also connected to the bottom side of the lifting plate 7. A steam-water mixing spray strip 11 is installed on the outside of the protective shell 8. A base 9 is also provided on the workbench 1. An outer collection box 10 is installed on both sides of the base 9. There are two support frames 2, which are symmetrically installed on both sides of the workbench 1. A telescopic cylinder 3 is installed on the top surface of each support frame 2. The telescopic ends of the telescopic cylinders 3 are movably connected to the bottom side of the support frame 2. The telescopic ends of the two telescopic cylinders 3 are connected to both ends of the lifting plate 7, which controls the up and down movement of the protective shell 8 and the lifting plate 7.

[0017] Specifically, the middle position of the lifting frame plate 7 is in the shape of an "n". Two horizontal frames 16 are symmetrically installed on the bottom side of the lifting frame plate 7 to support the cutting blade 4. A drive shaft is rotatably connected between the horizontal frames 16. The cutting blade 4 is installed on the outer surface of the drive shaft. Synchronous rotating drive belts 5 are connected to the output ends on both sides of the bidirectional motor 6. The other ends of the two synchronous rotating drive belts 5 are respectively connected to the two sides of the drive shaft, which can drive the drive shaft to rotate continuously.

[0018] Furthermore, transparent protective plates are vertically installed between the horizontal frame 16 and the lifting frame plate 7 to reduce the outward splashing of cutting debris. The synchronous rotating drive belt 5 is located outside the protective plates to prevent a large amount of debris from adhering during cutting. The cutting blade 4 is located between the protective plates. Grinding blocks 13 are fixedly installed on both ends of the drive shaft. A protective plate can also be provided on one side of the grinding block 13 to reduce the adhesion of debris generated during grinding to the synchronous rotating drive belt 5.

[0019] In this embodiment, two connecting rods 12 are symmetrically installed on the bottom surface of the protective shell 8. The connecting rods 12 are movably connected to both ends of the lifting frame plate 7. A compression spring 15 is provided on the outer surface of the connecting rod 12. The compression spring 15 is located between the lifting frame plate 7 and the protective shell 8, which can complete the protection in advance before the cutting blade 4 cuts. The deeper the lifting frame plate 7 descends, the more stable the connection between the protective shell 8 and the base 9 becomes. A connecting groove is provided in the middle of the bottom surface of the protective shell 8 to facilitate the cutting of the cutting blade 4.

[0020] A "V"-shaped through slot is provided at the middle of the bottom side of the protective shell 8 and the middle of the top side of the base 9. The inner wall of the through slot is spring-connected to a movable block 14, which can easily support the material and can block the through slot over a large area to avoid splashing a large amount of impurities. A collection slot is provided inside the base 9, and the connecting slot and the collection slot correspond to each other. Air-water mixing spray strips 11 are symmetrically installed on both sides of the protective shell 8 to prevent debris from splashing out of the through slot and to reduce the overall temperature around the cutting equipment. The outer collection box 10 is located on the bottom side of the air-water mixing spray strip 11 and is used to collect debris and liquid.

[0021] Working principle: When cutting phenolic resin reinforced pipes, the pipes are placed on the base 9 at the position of the movable block 14. Then, the telescopic cylinder 3 is controlled to extend downwards, and the lifting plate 7 will begin to move downwards. The protective shell 8 will follow and move downwards until the bottom surface of the protective shell 8 contacts the top surface of the base 9. At this time, the movable block 14 will contact the outside of the pipe under the action of the spring. At this time, the opening of the through groove is largely blocked. During the descent of the lifting plate 7, the bidirectional motor 6 is controlled to rotate. Driven by the synchronous rotation drive belt 5, the cutting blade 4 and the grinding block... All 13 will rotate and descend to a designated height. The cutting blade 4 will cut the material. During the cutting process, the air-liquid mixing spray bar 11 will work. The air-liquid mixture spray can prevent a large amount of debris from leaking out at the through groove. After the cutting is completed, the cut material is quickly pulled outward by the external clamping mechanism. Then, the telescopic cylinder 3 is controlled to extend downward again, so that the grinding block 13 can quickly grind the cut end of the material for defects such as burrs. During the grinding process, the external clamping mechanism rotates to make the material rotate, so as to achieve uniform grinding.
