Description

Technical Field

[0001] The utility model relates to the field of rubber sealing component processing, in particular to a finishing device for rubber sealing components. Background Art

[0002] Rubber parts are product accessories made of rubber as raw material. They are now widely used in various industries because of their good flexibility, sealing, insulation and many other excellent properties. Usually, rubber parts are mainly pressed by mold molding. During the molding process, due to process or other reasons, rubber parts will inevitably produce manufacturing defects such as flash and burrs. In areas where the precision requirements of rubber parts are relatively high, some flash needs to be removed, which is called trimming.

[0003] The utility model patent with announcement number CN 216230360 U discloses a trimming device for rubber parts, including a workbench, a double-knife trimming device, a single-knife trimming device and a turntable. The double-knife trimming device includes a first guide rail, a first bracket, a first support rod, a first cylinder, a first scraper, a connecting rod and a second scraper. The single-knife trimming device includes a second guide rail, a second bracket, a second support rod, a second cylinder and a third scraper. The turntable includes a sleeve column, a limit ring and a base. The rubber part is sleeved on the sleeve column. The turntable drives the rubber part to rotate. The combination of the single-knife trimming device and the double-knife trimming device can trim three sides of the rubber part.

[0004] In the actual use of the above case, when trimming the rubber seal, there is a lack of a limiting mechanism for the rubber part, which may make it impossible for the rubber part to be accurately fixed on the turntable during trimming, resulting in position offset during the trimming process, thereby affecting the accuracy and effect of trimming. If the rubber part moves or rotates during the trimming process, the cutting force and depth of the rubber part by the trimming device (such as a scraper) may be inconsistent, resulting in uneven edges of the trimmed rubber part and even damage. If the rubber part needs to be repeatedly adjusted in position during the trimming process, the workload and time of the operator will be greatly increased, and the overall production efficiency will be reduced. Therefore, the utility model provides a trimming device for rubber seals to meet the needs. Utility Model Content

At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0024] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides a trimming device for rubber seals, comprising a trimming table 1, a trimming assembly 2 for trimming rubber seals being fixedly connected to the top of the trimming table 1, and the trimming assembly 2 can trim the rubber seals after they are fixed;

[0025] In this embodiment, if Figures 1 to 3The fixing assembly shown is used to improve the stability of the rubber seal during trimming. The fixing assembly is connected to the trimming platform 1. The fixing assembly includes a hollow cone 4 fixedly connected to the inside of the fixing cavity 3. A plurality of flow holes 401 are provided on the outer wall of the hollow cone 4. Four fixing members 6 distributed in an annular manner are fixedly connected to the top of the hollow cone 4. The fixing member 6 includes a connecting portion 604 connected to the top of the hollow cone 4. The top of the connecting portion 604 is connected to a guide arc portion 601. The outside of the guide arc portion 601 is provided with a resistance portion 602. The cross section of the resistance portion 602 is "C" shaped. The guide arc portion 601 The thickness is 2mm. The hollow cone 4 and the external fixing member 6 are an integrally formed structure. The rubber seal is placed at the top center of the hollow cone 4. Four fixing members 6 are distributed in a ring around the rubber seal. The operator gently presses the rubber seal to make it contact with the hollow cone 4 and the fixing member 6. Due to the design of the guide arc portion 601, the rubber seal will be guided by the guide arc portion 601, making it easier to position. The abutment portion 602 (with a "C"-shaped cross section) further contacts closely with the outer peripheral surface of the rubber seal to fix it on the hollow cone 4. The trimming assembly 2 starts to work and the rubber seal is trimmed. The design of the flow hole 401 allows air to circulate, preventing the rubber seal from moving due to changes in air pressure during the trimming process. After the trimming is completed, the operator removes the rubber seal from the fixing assembly. Due to the elastic design of the guide arc portion 601 and the abutment portion 602, the rubber seal can be easily separated from the fixing assembly. Through the design of the fixing member 6, the rubber seal can be firmly fixed during the trimming process, reducing the possibility of movement or offset, thereby improving the stability and accuracy of the trimming. The introduction of the guide arc portion 601 makes it easier to position and fix the rubber seal, greatly simplifying the operation process. The annular distribution of the fixing member 6 and the "C"-shaped abutment portion 602 design enable the fixing assembly to be applicable to rubber seals of different sizes and shapes, thereby improving the versatility of the equipment. The hollow cone 4 and the fixing member 6 adopt an integrally formed structure, thereby ensuring the stability and durability of the structure and extending the service life of the equipment. The design of the flow hole 401 allows air to circulate inside the hollow cone 4, thereby avoiding the possibility of movement of the rubber seal due to changes in air pressure. Due to the elastic design of the guide arc portion 601 and the abutment portion 602, the rubber seal is not easily damaged during the fixing and removal process, thereby reducing the risk of product damage.

[0026] In this embodiment, if Figures 1 to 3The waste collection component shown is used to collect waste generated by dressing, and the waste collection component is connected to the dressing table 1. The waste collection component includes a fixed cavity 3 opened on the top of the dressing table 1, and a collecting plate 5 is slidably connected inside the dressing table 1. The collecting plate 5 is located directly below the fixed cavity 3. A central cavity 603 is opened inside the hollow cone 4, and the central cavity 603 is located directly above the collecting plate 5. The dressing component 2 dresses the rubber seal on the dressing table 1 to generate waste. Due to the action of gravity, the waste falls directly into the fixed cavity 3 on the top of the dressing table 1, and the waste passes through the fixed cavity 3 and enters the collecting plate 5 located directly below it. The collecting plate 5 is designed to be slidably connected inside the dressing table 1 to facilitate subsequent removal and cleaning. When there is a lot of waste, some of the waste may fall directly onto the collecting plate 5 through the central cavity 603 to ensure that the waste is completely Full collection. When the waste on the collecting plate 5 accumulates to a certain extent, the operator can slide the collecting plate 5 out from the inside of the dressing table 1 (along the sliding connection direction). After cleaning the waste on the collecting plate 5, the collecting plate 5 can be slid back to its original position to prepare for the next waste collection. The design of the fixed cavity 3 and the collecting plate 5 can ensure that the waste generated during the dressing process is effectively collected, avoiding the scattering and waste of waste. The collecting plate 5 is designed to be slidably connected inside the dressing table 1, which is convenient for the operator to take out and clean it, greatly simplifying the cleaning process. By timely cleaning the waste on the collecting plate 5, the continuous use of the dressing table 1 can be ensured, and production interruptions caused by cleaning waste are reduced. Waste is effectively collected, the impact of waste on the environment is reduced, and environmental protection requirements are met. The central cavity 603 is designed to assist in collecting waste, which can further ensure the complete collection of waste and reduce omissions.

[0027] The working principle provided by the utility model is that the operator gently presses the rubber seal to make it contact with the hollow cone 4 and the fixing part 6. Due to the design of the guide arc portion 601, the rubber seal will be guided by the guide arc portion 601, making it easier to position. The interference portion 602 (with a "C"-shaped cross section) is further in close contact with the outer peripheral surface of the rubber seal to fix it on the hollow cone 4. The trimming component 2 starts to work to trim the rubber seal. The trimming component 2 trims the rubber seal on the trimming table 1 to generate waste. Due to the action of gravity, the waste directly falls into the fixed cavity 3 on the top of the trimming table 1. The waste passes through the fixed cavity 3 and enters the collecting plate 5 located directly below it. The collecting plate 5 is designed to be slidably connected to the inside of the trimming table 1 to facilitate subsequent removal and cleaning.
