Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of machining and surface treatment, and specifically relates to a cylindrical metal piece rubberized product edge trimming device. BACKGROUND

[0002] In the field of industrial manufacturing, cylindrical metal piece rubberized products are widely used in various scenarios due to their excellent performance, such as seals, shock absorbers, and insulating parts. These products are usually made by coating or wrapping rubber material on the surface of metal parts to combine the strength of metal with the elasticity of rubber. However, after the rubberizing process is completed, excess rubber residue often appears on the edges of the products, which not only affects the appearance quality of the products, but also may cause assembly difficulties or performance degradation, so edge trimming needs to be performed.

[0003] Currently, the edge trimming operation for cylindrical metal piece rubberized products is mostly completed manually or assisted by simple mechanical tools. However, these methods have obvious shortcomings: manual edge trimming is inefficient, labor-intensive, and the quality of trimming is unstable due to differences in the technical level of operators; and existing simple mechanical tools generally have poor adaptability, making it difficult to meet the edge trimming needs of cylindrical metal piece rubberized products of different sizes and shapes. In addition, existing technologies lack precise positioning and protection measures for products during the trimming process, which can easily cause damage to the surface of metal parts or uneven removal of the rubber layer, further affecting product quality.

[0004] Therefore, developing a device specifically for trimming cylindrical metal piece rubberized products that can achieve efficient, precise, and stable trimming operations and effectively avoid damage to the products has become a technical problem that the industry urgently needs to solve. The development of this device will significantly improve production efficiency, improve product quality, and provide strong support for automated processing in related fields.

This rotating blade switching method not only reduces the frequency of cleaning the blade holder but also makes cleaning easier. In summary, this trimming device, through the cooperation of simple mechanical structures, achieves the trimming function while also featuring low cleaning frequency and simplified cleaning.

[0023] This utility model provides a trimming device for cylindrical metal parts coated with adhesive, the specific implementation of which is described in conjunction with the attached drawing. Figure 1 To be continued Figure 3 Please provide a detailed explanation. For example... Figure 1 As shown, the trimming device includes a base 1, a drive housing 2, a trimming housing 3, slide rails 4, and a waste guide plate 5. The base 1 serves as the supporting structure for the entire device. The drive housing 2 is fixedly mounted on one side of its top, while the other side is connected to the drive housing 2 via a support plate, securing two spaced slide rails 4. The trimming housing 3 is installed between the slide rails 4. The trimming housing 3 has an open top, and an inclined waste guide plate 5 is installed between its bottom and the base 1 to guide waste and dust generated during the trimming process to a designated location for cleaning. The output end of the drive housing 2 is connected to the trimming housing 3 via a linkage structure, enabling the trimming housing 3 to reciprocate along the slide rails 4.

[0024] The trimming box 3 contains a trimming assembly, the specific structure of which is as follows: Figure 2 As shown, the trimming assembly includes a cylindrical blade holder 6 rotatably mounted within the trimming housing 3. The cylindrical blade holder 6 has multiple evenly arranged blade grooves for cutting the adhesive layer. To ensure stable operation of the cylindrical blade holder 6, the trimming assembly also includes two arc-shaped limiting blocks 7 and two inclined guide blocks 8. The arc-shaped limiting blocks 7 are spaced apart along the axial direction of the cylindrical blade holder 6 and fixed to the inner walls of both sides of the trimming housing 3, while the inclined guide blocks 8 are spaced apart along the radial direction of the cylindrical blade holder 6 and fixed to the inner walls of both sides of the trimming housing 3. The heights of the arc-shaped limiting blocks 7 and the inclined guide blocks 8 are both greater than the height of the axis of the cylindrical blade holder 6, and their surfaces mate with the cylindrical blade holder 6 to form a closed trimming chamber. The trimming chamber is composed of an arc-shaped limiting block 7, an inclined guide block 8, the top surface of a cylindrical tool holder 6, and the inner wall of the trimming box 3. It is used to accommodate and trim cylindrical metal parts with adhesive coating that need to be trimmed.

[0025] To enable the reciprocating movement of the trimming box 3, main pulleys 9 are provided on both sides of the trimming box 3, which cooperate with the slide rail 4. The main pulleys 9 are equipped with a pawl structure with unidirectional rotation. The main pulleys 9 are connected to the cylindrical tool holder 6 via a reduction mechanism. When the trimming box 3 reciprocates on the slide rail 4, the unidirectional rotation characteristic of the main pulleys 9 allows the cylindrical tool holder 6 to rotate continuously at a low speed. The core advantage of this design is that the slow rotation of the cylindrical tool holder 6 allows for switching between tool slot areas, thus avoiding the problem of a single tool slot becoming clogged or worn due to prolonged use. Furthermore, due to the structural characteristics of the cylindrical tool holder 6, its surface can repeatedly contact the adhesive layer, thereby achieving multiple trimming processes on the adhesive layer and further improving the trimming effect.

[0026] like Figure 1 As shown, a secondary housing 10 is fixedly connected to the side of the trimming housing 3 away from the drive housing 2. Secondary pulleys 11, which cooperate with the slide rail 4, are rotatably mounted on both sides of the secondary housing 10. The secondary pulleys 11, the main pulley 9, and the cylindrical tool holder 6 are all in the same plane, ensuring smooth movement of the trimming housing 3 on the slide rail 4. A rectangular groove is provided at the joint between the trimming housing 3 and the secondary housing 10. A vertically arranged guide rod 14 is fixedly connected inside the secondary housing 10, and a horizontally arranged push rod 13 is slidably connected to the guide rod 14. A scraper 12 is fixedly connected to one end of the push rod 13, and a flexible cleaning layer is provided on the scraper 12 for cleaning the surface of the cylindrical tool holder 6. A double-end bracket is connected to the other end of the push rod 13, and pins are fixedly connected to both ends of the double-end bracket. Turntables 15 are provided on both sides inside the secondary housing 10, and elliptical tracks are provided on the turntables 15, which cooperate with the pins. When the trimming box 3 moves back and forth, the cooperation between the turntable 15 and the pin rod enables the scraper 12 at one end of the push rod 13 to move back and forth, thereby contacting the surface of the cylindrical tool holder 6 and completing the cleaning work on its surface.

[0027] To prevent dust from entering the interior of the secondary housing 10, an elastic sealing layer 16 is fixedly connected to the push rod 13. The elastic sealing layer 16 is sealed to the inner wall of the secondary housing 10 and is located between the guide rod 14 and the scraper 12. The elastic sealing layer 16 isolates the internal space of the secondary housing 10 into a closed chamber, in which the double-end bracket and the turntable 15 are located, thus effectively protecting the internal mechanical structure of the secondary housing 10 from the influence of the external environment. In addition, airflow channels are provided in both the scraper 12 and the push rod 13. Multiple airflow holes are provided on the side of the scraper 12 located on the flexible cleaning layer. An exhaust pipe 17 connected to the airflow channels is fixedly connected to the double-end bracket. An air inlet pipe 18 is fixedly installed on the top of the secondary housing 10. One-way valves are provided on both the exhaust pipe 17 and the air inlet pipe 18. A dust cover is fixedly connected to the top of the air inlet pipe 18. By cooperating with the intake pipe 18 and the exhaust pipe 17, a stable airflow circulation can be formed inside the auxiliary housing 10, thereby further improving the cleaning effect of the scraper 12 on the surface of the cylindrical blade holder 6.

[0028] like Figure 2 As shown, a detection box 19 is fixedly connected to the side of the trimming box 3 opposite to the rectangular groove, and a laser rangefinder 20 is installed inside the detection box 19. A transparent window is fixedly provided at the joint between the detection box 19 and the trimming box 3, and the laser rangefinder 20 monitors the thickness of the adhesive layer in real time during the trimming process through the transparent window. Electromagnetic clutches are fixedly connected to both sides of the auxiliary box 10 to drive the auxiliary pulley 11 and the turntable 15. When the cylindrical knife holder 6 needs to be cleaned, the electromagnetic clutch is activated, establishing the drive connection between the turntable 15 and the auxiliary pulley 11, thereby driving the scraper 12 to reciprocate. When the cleaning work is completed, the electromagnetic clutch is disengaged, the turntable 15 stops rotating, and the scraper 12 also stops moving.

[0029] The trimming chamber 3 has a waste material bin door 21 on one side that can be closed or opened for periodically cleaning waste and dust inside. The waste material bin door 21 not only facilitates cleaning of the trimming chamber by operators but also effectively prevents waste accumulation from affecting the trimming effect. Furthermore, the tilt angle of the waste material guide plate 5 is precisely designed to ensure that waste and dust smoothly slide to the designated position, thereby reducing the frequency of manual cleaning.

[0030] In practical applications, the trimming device of this invention is suitable for trimming various cylindrical metal parts coated with adhesive. For example, in the automotive parts manufacturing industry, some cylindrical metal parts require adhesive coating to enhance their corrosion resistance, and the trimming process is a key step in ensuring the surface quality of the adhesive layer. With this device, the operator can place the cylindrical metal part coated with adhesive to be trimmed into the trimming chamber. After starting the drive unit 2, the trimming unit 3 moves rapidly back and forth on the slide rail 4, while the cylindrical blade holder 6 rotates continuously at a low speed, thus achieving efficient trimming of the adhesive layer. During the trimming process, the laser rangefinder 20 monitors the thickness change of the adhesive layer in real time. When the thickness of the adhesive layer in a certain area is detected to be insufficient, the trimming effect can be optimized by adjusting the moving speed of the trimming unit 3 or the rotation speed of the cylindrical blade holder 6. Simultaneously, the scraper 12 cleans the surface of the cylindrical blade holder 6 through reciprocating movement, ensuring that the blade groove remains clean, thereby extending the service life of the blades and reducing production costs.

[0031] In summary, this utility model, through its ingenious mechanical structure design and reasonable functional layout, not only achieves efficient edge trimming of cylindrical metal parts coated with adhesive, but also significantly reduces the frequency of tool cleaning and maintenance costs. It also boasts advantages such as convenient waste removal and stable, reliable operation, and has broad application prospects and promotional value.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
