Description

Technical Field

[0001] The present invention relates to the field of sprocket brake discs, and particularly to a processing technology and a brake disc for a driving sprocket brake disc. Background Art

[0002] As is well known, a brake disc is an important component commonly found on many devices. And for the stability of the brake disc, the overall assembly structure of the brake disc is often relatively complex. Currently, the friction plate of a driving sprocket brake disc is generally an independent piece, which is integrally installed on the attached sprocket. However, since the friction plate of the brake disc is a consumable item, when it wears and needs to be replaced, the operation is difficult. In addition, during the use of the device, the wear degrees of the friction plates on the brake disc are different, that is, some areas are worn more severely and need to be replaced in time, while some areas are worn slightly and do not need to be replaced. However, the existing assembly structure and method between the brake disc and the friction plate can only replace the entire friction plate, which causes a great deal of waste of resources and thus increases the use cost of the device.

[0003] Therefore, a new processing technology and a brake disc for a driving sprocket brake disc are provided to solve the problems of complex assembly structure, difficult assembly, and waste of resources existing in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to provide a processing technology and a brake disc for a driving sprocket brake disc to solve the problems of complex assembly structure, difficult assembly, and waste of resources existing in the prior art.

[0005] To achieve the above purpose, a processing technology for a driving sprocket brake disc of the present invention includes the following steps: Obtain raw materials and prepare a brake and a plurality of friction plates; In the pretreatment stage, the first surface of the brake is processed to make the first surface of the brake in a first state, and the second surfaces of the plurality of friction plates in contact with the first surface are processed to make the second surfaces of the plurality of friction plates in a second state; In the first-stage processing, a first adhesive coating is applied to the first surface of the brake and / or the second surfaces of the plurality of friction plates, and then the two are paired and placed; In the second-stage processing, the paired brake and the plurality of friction plates are heated to a first temperature range; In the third-stage processing, turning is performed after the brake and the plurality of friction plates are cooled.

[0006] Further, in the pretreatment stage, the first surface of the brake is processed with a solvent to make the first surface in the first state; The second surfaces of the plurality of friction plates are treated with a solvent so that the second surfaces are in the second state.

[0007] Further, the solvent includes a first solvent and a second solvent. The first solvent is one or a combination of xylene, diesel oil, or gasoline, and the second solvent is acetone.

[0008] Further, the first surface and / or the second surface after being treated with the solvent are re-treated so that the contact area of the first surface and / or the second surface after the re-treatment is larger than its original contact area.

[0009] Further, the re-treatment is sandblasting treatment, and the sandblasting treatment uses emery with a mesh size of 60 - 80.

[0010] Further, the number of layers of the first adhesive coating in the first treatment stage is at least two layers.

[0011] Further, the thickness of the first adhesive coating in the first treatment stage is 0.5 mm - 1 mm.

[0012] Further, in the first treatment stage, in summer, after the first adhesive coating is applied, it needs to be left to dry for 20 min - 40 min; in winter, after the first adhesive coating is applied, it needs to be left to dry for 50 - 70 min.

[0013] Further, in the second treatment stage, a fixture is used to clamp the brake and the friction plate so that a small amount of glue overflows from the periphery of the friction plate. After the clamped brake and friction plate are heated to the first temperature range, they are kept warm for at least 1 h.

[0014] A brake disc is made by the above processing technology, and the number of the friction plates is 2 - 10 pieces.

[0015] The processing technology of the present invention solves the problems existing in the prior art such as complex assembly structure, difficult assembly, and waste of resources. At the supplier end, the brake disc made by the above process greatly reduces the assembly difficulty, improves the assembly efficiency and assembly accuracy, thereby reducing the production cost; at the user end, it reduces the time and difficulty for the user to replace the friction plate in the later stage, thereby reducing the later maintenance cost of the user end.

Embodiment

[0017] The processing technology of a driving sprocket brake disc of the present invention and the brake disc are described through specific embodiments. Those skilled in the art can obviously make changes, or appropriate modifications and combinations to the processing technology of the driving sprocket brake disc and the brake disc described herein without departing from the content, spirit and scope of the present invention to implement and apply the technology of the present invention, and they are all regarded as included in the protection scope of the present invention.

[0018] The following further describes a processing technology of a driving sprocket brake disc and the brake disc provided by the present invention.

[0019] Please refer to Figures 1 to 6 , a processing technology of a driving sprocket brake disc, characterized by including the following steps: Obtain raw materials, and prepare a brake 10 and a plurality of friction plates 20; In the preprocessing stage, the first surface 11 of the brake 10 is processed to make the first surface 11 of the brake 10 in a first state, and the second surfaces 21 of the plurality of friction plates 20 in contact with the first surface 11 are processed to make the second surfaces 21 of the plurality of friction plates 20 in a second state; In the first-stage processing, a first adhesive coating is applied to the first surface 11 of the brake 10 and / or the second surfaces 21 of the plurality of friction plates 20, and then the two are paired and placed; In the second-stage processing, the paired brake 10 and the plurality of friction plates 20 are heated to a first temperature range; In the third - stage processing, machining is carried out after the brake 10 and the multiple friction plates 20 are cooled completely.

[0020] In one embodiment, in the pre - treatment stage, the first surface 11 of the brake 10 is treated with a solvent so that the first surface 11 is in the first state.

[0021] In one embodiment, in the pre - treatment stage, the first surface 11 of the brake 10 is treated with a first solvent and a second solvent so that the first surface 11 is in the first state.

[0022] In one embodiment, in the pre - treatment stage, the second surfaces 21 of the multiple friction plates 20 are treated with a solvent so that the second surfaces 21 are in the second state.

[0023] In one embodiment, the first solvent is one or a combination of xylene, diesel oil, or gasoline. The use of the first solvent is mainly to remove the oil stain on the surface of the brake 10, thereby avoiding the subsequent problem of the first adhesive coating not sticking firmly.

[0024] In one embodiment, the second solvent is acetone. In one embodiment, after using the first solvent to remove the oil stain, wipe it clean with a cloth dipped in acetone and set it aside.

[0025] Of course, in other embodiments, in the pre - treatment stage, the first surface 11 of the brake 10 and / or the second surface 21 of the friction plate 20 can be treated with other one or more combinations of solvents, as long as the selected solvent can remove the oil stain on the first surface 11 and / or the second surface 21.

[0026] In one embodiment, the first surface 11 and / or the second surface 21 after being treated with the solvent are re - treated so that the contact area of the first surface 11 and / or the second surface 21 after the re - treatment is larger than its original contact area.

[0027] In one embodiment, the re - treatment is sand - blasting treatment, and the sand - blasting treatment uses emery with a mesh size of 60 - 80. In one embodiment, emery with a mesh size of 60, 65, 70, 75, or 80 is used for sand - blasting treatment. Of course, in other embodiments, it is not excluded to use a combination of the above two or more kinds of sand for sand - blasting treatment. After sand - blasting, use an air gun to clean the sand - blasted surface. The role of sand - blasting treatment is to increase the roughness of the adhesive surface, that is, to increase the contact area of the adhesive surface, so that the subsequent paste is more firm.

[0028] In one embodiment, the number of layers of the first adhesive coating in the first processing stage is at least two. In one embodiment, the number of layers of the first adhesive coating is two. Coating two layers of the first adhesive coating has more advantages in terms of company cost and efficiency. Of course, in other embodiments, the number of layers of the first adhesive coating can also be three, four or more layers, and it is also possible to be one layer.

[0029] In one embodiment, the thickness of the first adhesive coating in the first processing stage is 0.5 mm - 1 mm. During the coating process, it is necessary to coat evenly without showing the bottom.

[0030] In one embodiment, the first adhesive coating in the first processing stage is glue. In one embodiment, before coating the glue, the glue liquid needs to be stirred evenly, and then a paintbrush is used for coating. Of course, to ensure quality, the original packaged glue within the shelf life can be used. In addition, besides the paintbrush, other tools can also be used for coating, as long as the glue liquid can be evenly adhered to the first surface 11 and the second surface 21. The glue in this embodiment can be selected as the glue of model FH - 118.

[0031] In one embodiment, in the first processing stage, in summer, after the first adhesive coating is coated, it needs to be left to dry for 20 min - 40 min; in winter, after the first adhesive coating is coated, it needs to be left to dry for 50 min - 70 min. In one embodiment, in summer, a paintbrush is used to evenly coat two layers of the first adhesive coating on the surface where the brake 10 and the friction plate 20 are in contact. After the first adhesive coating is coated, it needs to be left to dry for 20 min, 25 min, 30 min, 35 min, 40 min until the first adhesive coating is no longer sticky. In winter, after the first adhesive coating is coated, it needs to be left to dry for 50 min, 55 min, 60 min, 65 min, 70 min until the first adhesive coating is no longer sticky.

[0032] In one embodiment, in the first processing stage, after the drying is completed, a plurality of the friction plates 20 are pasted on the place where the brake 10 is coated with the first adhesive coating. During this process, it is necessary to ensure that the outer diameter surface of the friction plate 20 is flush with the outer diameter surface of the brake 10.

[0033] In one embodiment, the step difference between the friction plate 20 and the brake 10 is controlled within ±0.5 mm.

[0034] In one embodiment, in the second processing stage, a fixture is used to clamp the brake 10 and the friction plate 20, so that a small amount of glue overflows from the periphery of the friction plate 20. Clamping and extruding a small amount of glue through the fixture can facilitate the discharge of air, enabling the first surface 11 and the second surface 21 to closely adhere to each other, thereby improving the firmness. The above-mentioned fixture can be a professional fixture or an ordinary fixture with a pressing function, and no excessive restrictions are imposed here. In one embodiment, a professional fixture is used, and bolts and nuts are used to clamp the brake 10 and the friction plate 20, and the nut is evenly tightened with a wrench until a small amount of glue overflows from the periphery of the friction plate 20.

[0035] In one embodiment, in the second processing stage, after heating to the first temperature range, it is necessary to keep warm for at least 1 h, and the first temperature range is 170°C - 180°C.

[0036] In one embodiment, the clamped brake 10 and friction plate 20 are placed in an oven and heated to 170°C - 180°C, kept warm for more than 1 h, and then taken out after cooling to room temperature with the oven. Subsequently, the fixture is loosened, the brake 10 equipped with the friction plate 20 is taken out, and the excess glue around the friction plate 20 is removed. In a specific embodiment, the oven selected is a ZYH-60 type oven.

[0037] In one embodiment, in the third processing stage, after cooling is completed, the above components are machined by a lathe according to the requirements of the drawing.

[0038] Please refer to Figures 7 to 10 , a brake disc, prepared by the above processing technology, includes: a brake 10, the brake 10 is annular, specifically including a first ring 10a and a second ring 10b, the first ring 10a is arranged on the outer periphery of the second ring 10b, the first ring 10a and the second ring 10b are integrally formed, and an installation channel 12 is formed on the inner periphery of the second ring 10b to facilitate its installation on the driving sprocket brake disc assembly. A first surface 11 is arranged on the first ring 10a, and the first surface 11 is arranged on the upper surface of the first ring 10a.

[0039] In one embodiment, the friction plate 20 is in the shape of a truncated circular ring. Specifically, the friction plate 20 includes a body, and the body is provided with a first end 20a and a second end 20b away from the first end 20a. Mounting holes 22 are formed in the body near the first end 20a and the second end 20b. In one embodiment, the number of the mounting holes 23 is two, and the two mounting holes 23 are distributed at both ends of the friction plate 20 to improve the mounting stability of the friction plate 20. Of course, in other embodiments, the number of the mounting holes 23 can be three, four, or more. For example, when the size of the brake 10 remains unchanged and the number of the friction plates 20 is smaller, in order to ensure the coverage rate of the friction plate 20, the area of a single friction plate 20 will become larger. At this time, in order to ensure the mounting stability of the friction plate 20, more mounting holes 23 may need to be formed.

[0040] In addition, each friction plate 20 is provided with a second surface 21 and a third surface opposite to the second surface 21. Among them, the second surface 21 is the lower surface of the friction plate 20, and the third surface is the upper surface of the friction plate 20. When the friction plate 20 is mounted on the brake 10 through a fastener, the first surface 11 is in contact with the second surface 21, and the fastener penetrates through the friction plate 20 from one side of the third surface through the mounting hole 23 and extends into the brake 10, so as to assemble the friction plate 20 onto the brake 10. Among them, a first adhesive coating is filled between the first surface 11 and the second surface 21.

[0041] In one embodiment, the number of the friction plates 20 is 2 - 10, and can be 2, 3, 4, 5, 6, 7, 8, 9, or 10.

[0042] In one embodiment, a plurality of the friction plates 20 are evenly distributed along the circumferential direction of the brake 10.

[0043] In one embodiment, a plurality of the friction plates 20 are detachably connected to the brake 10.

[0044] The processing technology of the present invention solves the problems existing in the prior art, such as complex assembly structure, difficult assembly, and resource waste. At the supplier side, the brake disc prepared by the above technology greatly reduces the assembly difficulty, improves the assembly efficiency and assembly accuracy, and thus reduces the production cost; at the user side, it reduces the time and difficulty for the user to replace the friction plate 20 later, and thus reduces the later maintenance cost at the user side.

[0045] The specific embodiments described above further elaborate on the object, technical solution, and beneficial effects of the present invention. It should be understood that the above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
