Description

Technical Field

[0001] This utility model relates to the technical field of film trimming equipment, specifically to a trimming device for the production of rubber brake films. Background Technology

[0002] A diaphragm is a type of rubber diaphragm sealing product, which is a rubber component used in automobile brake chambers to transmit pressure.

[0003] After the rubber film is produced, burrs and flash often remain on its outer edge, which affects the appearance of the film and the quality of the finished product. Therefore, the film often needs to be trimmed before leaving the factory.

[0004] Conventional trimming is mostly done manually, using pliers (knives) to tear and cut burrs and flash. Since there are a lot of burrs and flash on the outer edge of the film, it is time-consuming and laborious to manually trim them one by one, resulting in poor work efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, a trimming device for the production of rubber brake diaphragms is provided. This device solves the problem that conventional trimming in the prior art is mostly done manually, using pliers (knives) to tear and cut burrs and flash. Since there are a lot of burrs and flash on the outer edge of the diaphragm, it is time-consuming and laborious to manually trim them one by one, resulting in poor work efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a trimming device for the production of rubber brake diaphragms, comprising a rotating base for placing the rubber diaphragm, a telescopic scraping part for trimming the burrs and flash on the outer edge of the rubber diaphragm, and a pressing part for ensuring the stability of the rubber diaphragm during the trimming process.

[0007] The rotating base consists of a base plate and a movable plate, with the movable plate rotatably connected to the top surface of the base plate;

[0008] The telescopic scraping part includes a fixing frame fixed in an inverted L shape at the edge of the top surface of the substrate. The end of the fixing frame is an opening. A scraper is vertically arranged outside the opening. The scraper slides on the upper surface of the movable plate. An movable assembly for adjusting the position of the scraper according to the size of the film is arranged inside the opening.

[0009] The pressing part includes a movable ring rotatably disposed on the outer periphery of the substrate, a connecting frame fixed in an inverted L shape on the top surface of the movable ring, and a lifting type pressing assembly disposed at the end of the connecting frame.

[0010] Preferably, the lifting pressurization assembly includes a connecting cylinder fixed to the end of the connecting frame and an assembled pressure plate slidably disposed below the connecting cylinder. The connecting cylinder has a built-in drive component for lifting and lowering the assembled pressure plate.

[0011] Preferably, the assembled pressure plate consists of a ring-shaped pressure member and two semi-ring-shaped extension members, with the two extension members mirror-distributed on the outer periphery of the pressure member.

[0012] Preferably, the driving component includes a transmission screw vertically disposed inside the connecting cylinder and a threaded sleeve threaded to the shaft of the transmission screw. Both sides of the connecting cylinder wall are vertically provided with sliding slots, and a movable frame is slidably disposed in the sliding slots. One end of the movable frame is fixedly connected to the threaded sleeve, and the other end of the movable frame is fixedly connected to the pressure member. One end of the transmission screw rotates out of the connecting cylinder and is fixed with a knob block.

[0013] Preferably, the movable assembly includes a telescopic rod that is slidably disposed in the opening and fixedly connected to the scraper. The telescopic rod has a plurality of locking holes equidistantly provided. The top of the fixing frame is provided with a screw, which is threaded into the opening and extends into one of the locking holes.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] (1) By setting up a rotating base and a telescopic scraping part, the rubber film to be trimmed is placed on the surface of the movable plate and the outer edge of the film is made to contact the scraper. Then, the movable plate is rotated one round, and the scraper, which is kept in a relatively fixed state, scrapes the surface of the film one round, thereby efficiently removing burrs and flash from different positions of the film and improving the processing speed.

[0016] (2) By setting up the movable group, the push and pull scraper and the telescopic rod are simultaneously stretched and slid within the opening of the fixed frame. This makes it convenient to quickly adjust the position of the scraper on the movable plate according to the size of the film to be processed, so that the scraper can contact the outer edge of different sizes of films and perform outer surface trimming operations on films of different sizes.

[0017] (3) By setting up an assembly plate, two extension pieces are assembled in mirror image of the outer diameter of the pressure piece according to the outer diameter of the film to be processed, so that the assembly plate formed by them is compatible with the size of the film to be processed. When the assembly plate presses down on the film, the bottom edge of the extension piece presses down to contact the top edge of the film. In this way, while ensuring the pressing effect on the film, the outer edge of the film is appropriately made to have a certain rigidity due to the extrusion, thereby improving the scraping effect of the scraper on the burrs and flashes on the outer edge of the film.

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Reference Figure 1-4 As shown, a trimming device for producing rubber brake diaphragms includes a rotating base for placing the rubber diaphragm and a telescopic scraping part for trimming the burrs and flash on the outer edge of the rubber diaphragm.

[0026] The rotating base consists of a base plate 1 and a movable plate 2, with the movable plate 2 rotatably connected to the top surface of the base plate 1.

[0027] The telescopic scraping part includes a fixing frame 13 fixed in an inverted L shape at the edge of the top surface of the substrate 1. The end of the fixing frame 13 is an opening, and a scraper 12 is vertically arranged outside the opening. The scraper 12 slides on the upper surface of the movable plate 2.

[0028] By using a rotating base and a telescopic scraping part, the rubber film to be trimmed is placed on the surface of the movable plate 2, and the outer edge of the film contacts the scraper 12. Then, the movable plate 2 is rotated one revolution, and the scraper 12, which is kept in a relatively fixed state, scrapes the surface of the film around one revolution, thereby efficiently removing burrs and flash from different positions of the film and improving the processing speed.

[0029] Furthermore, referring to Figure 1 and Figure 3 As shown, it is worth noting that the opening is equipped with a movable assembly for adjusting the position of the scraper 12 according to the size of the film.

[0030] The active assembly includes a telescopic rod 14 that is slidably disposed in the opening and fixedly connected to the scraper 12. Several locking holes 14 are equally spaced on the telescopic rod 14. A screw is provided on the top of the fixing frame 13. The screw thread passes through the opening and extends into one of the locking holes 14.

[0031] With the setting of the movable group, the push and pull scraper 12 and the telescopic rod 14 are simultaneously stretched and slid within the opening of the fixed frame 13. This makes it convenient to quickly adjust the position of the scraper 12 on the movable plate 2 according to the size of the film to be processed, so that the scraper 12 can contact the outer edge of films of different sizes and models, and perform outer surface trimming operations on films of different sizes and models.

[0032] After the scraper 12 has completed its sliding adjustment, a simple knob screw is all that is needed to insert the screw into the corresponding locking hole 14 under the thread structure. The screw and the locking hole 14 can effectively lock the telescopic rod 14 and the scraper 12 as a whole, ensuring the scraper 12 is secure after adjustment.

[0033] Furthermore, referring to Figure 1 and Figure 2 As shown, it is worth noting that it also includes a pressing part to ensure the stability of the rubber film during the trimming process;

[0034] The pressing part includes a movable ring 3 rotatably disposed on the outer periphery of the substrate 1, a connecting frame 4 fixed in an inverted L shape on the top surface of the movable ring 3, and a lifting type pressing assembly disposed at the end of the connecting frame 4;

[0035] By setting up the pressing section, the lifting pressure unit can apply pressure to the film from top to bottom, thereby fixing the film on the movable plate 2 to ensure the stability of the film during the rotating trimming process. Furthermore, by using the movable ring 3 that is rotatably connected to the outer periphery of the substrate 1, when the movable plate 2 rotates, the lifting pressure unit can rotate the movable ring 3 together with it under the rubber friction characteristics, reducing the resistance to the rotation of the movable plate 2.

[0036] Furthermore, referring to Figure 4 As shown, it is worth noting that the lifting pressurization assembly includes a connecting cylinder 6 fixed to the end of the connecting frame 4 and an assembled pressure plate slidably disposed below the connecting cylinder 6. The connecting cylinder 6 has a built-in drive component for the lifting and lowering movement of the assembled pressure plate.

[0037] By using the lifting and pressurizing assembly, the assembled pressure plate slides down until it contacts the rubber diaphragm, and the assembled pressure plate can effectively compress and fix the diaphragm from top to bottom.

[0038] Furthermore, referring to Figure 1 , Figure 2 as well as Figure 4 As shown, it is worth noting that the assembled pressure plate consists of a ring-shaped pressure member 5 and two semi-ring-shaped extension members 10, with the two extension members 10 mirror-distributed on the outer periphery of the pressure member 5.

[0039] By setting up an assembled pressure plate, two extension pieces 10 are assembled in mirror image of the outer diameter of the pressure piece 5 according to the outer diameter of the membrane to be processed, so that the assembled pressure plate is adapted to the size of the membrane to be processed. When the assembled pressure plate presses down on the membrane, the bottom edge of the extension piece 10 presses down to contact the top edge of the membrane. In this way, while ensuring the pressing effect on the membrane, the outer edge of the membrane is appropriately made to have a certain rigidity due to the extrusion, thereby improving the scraping effect of the scraper 12 on the burrs and flashes on the outer edge of the membrane.

[0040] Furthermore, referring to Figure 2 As shown, it is worth noting that a connecting block 11 is fixed on the inner wall of the extension 10, and a fixing port adapted to the connecting block 11 is opened on the outer edge of the pressure member 5. The connecting block 11 is detachably fixed in the fixing port by bolts.

[0041] When fitting the extension piece 10 onto the pressure piece 5, it is important to simultaneously insert the connecting block 11 into the fixing port. In this way, the connecting block 11, in conjunction with the fixing port, can initially position the extension piece 10. Then, by using bolts to lock the connecting block 11 into the fixing port, the extension piece 10 and the pressure piece 5 can be effectively fixedly connected.

[0042] Furthermore, referring to Figure 4 As shown, it is worth noting that the driving component includes a transmission screw 8 vertically arranged inside the connecting cylinder 6 and a screw sleeve 7 threadedly connected to the shaft of the transmission screw 8. Both sides of the connecting cylinder 6 are vertically provided with sliding slots, and a movable frame 9 is slidably arranged in the sliding slots. One end of the movable frame 9 is fixedly connected to the screw sleeve 7, and the other end of the movable frame 9 is fixedly connected to the pressure member 5. One end of the transmission screw 8 rotates out of the connecting cylinder 6 and is fixed with a knob block.

[0043] Rotating the knob causes the transmission screw 8 to rotate inside the connecting cylinder 6. The threaded sleeve 7 can then slide down through the threaded structure during the rotation of the transmission screw 8, and the movable frame 9 simultaneously pushes and pulls the pressure component 5 downwards.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
