Description

Technical Field

[0001] This utility model relates to a tooling for trimming vulcanized rubber on the surface of aluminum plates, belonging to the field of rubber processing technology. Background Technology

[0002] In industrial production, rubber is often bonded to aluminum plates via vulcanization to form composite structural components, such as certain gaskets and shock-absorbing pads. After vulcanization, an irregular ring of excess rubber burrs remains at the joint edges of the aluminum plates, which needs to be removed. Currently, the common method of trimming relies on workers manually trimming the edges using hand tools such as utility knives and scrapers. This method has the following significant drawbacks: Inefficient: Manual operation is slow, labor-intensive, and difficult to meet the needs of mass production; Unstable quality: Relying entirely on the experience and feel of workers can easily damage the aluminum plate substrate, or result in incomplete trimming, leading to poor product consistency and low yield. Poor safety: Sharp knives pose a risk of cutting the operator during manual operation.

[0003] In the prior art, Chinese utility model patent authorization announcement number CN213440686U discloses a rubber sealing ring trimming fixture, which is suitable for circular rubber rings but not for other shapes, such as rectangles. In contrast, Chinese invention patent application number 202311856858.3 discloses a trimming fixture for rubber products with iron parts. This invention is suitable for rubber products with non-circular iron parts. It uses vacuum adsorption and rotation equipment in conjunction with a milling machine for circumferential cutting, which can improve efficiency, but its operation is relatively cumbersome, requiring air pumps for vacuuming and milling machines, resulting in high costs.

[0004] Therefore, we have made improvements to this by proposing a tooling for trimming vulcanized rubber on the surface of aluminum plates. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model designs a simple and low-cost tooling for trimming vulcanized rubber on the surface of aluminum plates. It fixes the aluminum plate to the base using a pressure plate and employs limiting pins for precise positioning, exposing the area of ​​rubber to be trimmed. This allows for manual trimming with a utility knife, eliminating the need for complex equipment.

[0006] The technical solution adopted by this utility model is a tooling for trimming vulcanized rubber on the surface of aluminum plate, including a base, an aluminum plate and a pressure plate. The upper surface of the base is provided with a receiving groove for placing the aluminum plate. Rubber to be trimmed is bonded to the aluminum plate. When the pressure plate presses on the aluminum plate, the pressure plate cooperates with the base to fix the aluminum plate. The area of ​​the rubber to be trimmed is exposed outside the pressure plate and trimmed by a trimming tool.

[0007] As a further embodiment of this utility model, a positioning pin is provided between the pressure plate and the base.

[0008] As a further embodiment of this utility model, each corner of the receiving groove is provided with a limiting pin.

[0009] As a further embodiment of this utility model, each corner of the receiving groove is a superior arc, and the arc opening of the superior arc faces the center of symmetry of the base.

[0010] As a further embodiment of this invention, the depth of the receiving groove is equal to the thickness of the aluminum plate.

[0011] This utility model discloses a tooling for trimming the surface of vulcanized rubber on aluminum plates. Its beneficial effects are as follows compared with the prior art: 1. Simple structure and low cost: It eliminates equipment such as air pumps and milling machines, and only requires basic mechanical components, thus reducing manufacturing costs. 2. Easy to operate: It can be quickly positioned and fixed by limit pins and positioning pins, and no power equipment is required during the trimming process; 3. High stability: The pressure plate and base work together to prevent the aluminum plate from moving, avoid damage to the product during trimming, improve trimming efficiency, and ensure the consistency and stability of the quality of the vulcanized rubber on the aluminum plate surface after trimming. Attached Figure Description

[0012] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0014] As shown in the figure: 1. Pressure plate; 2. Aluminum plate; 3. Base; 4. Positioning pin; 5. Limiting pin; 6. Receiving groove; 7. Positioning hole; 8. Limiting hole; 9. Rubber. Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this utility model or its application or use. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] To further understand the utility model content of this utility model, the technical solution will be further described below in conjunction with specific embodiments.

[0017] Example 1: As Figures 1-3 As shown, this embodiment provides a tooling for trimming the surface of vulcanized rubber on aluminum plates, including a pressure plate 1, an aluminum plate 2, a positioning pin 4, a limiting pin 5, a base 3, and a trimming tool, which is a utility knife in this embodiment. The base 3 has a receiving groove 6 for placing the aluminum plate 2. Each corner of the receiving groove 6 has a limiting hole 8. One end of the limiting pin 5 is inserted into the limiting hole 8 with an interference fit. Both ends of the pressure plate 1 and the base 3 have positioning holes 7. Rubber 9 to be trimmed is bonded to the aluminum plate 2 by a vulcanization process. The rubber 9 is rectangular in shape. When the aluminum plate 2 to be trimmed is placed in the receiving groove 6 of the base 3, and the pressure plate 1 presses on the aluminum plate 2, the pressure plate 1 and the base 3 are inserted into the positioning hole 7 with an interference fit of the positioning pin 4. The pressure plate 1 and the base 3 cooperate to fix the aluminum plate 2. The area of ​​the rubber 9 to be trimmed is exposed outside the pressure plate 1 and trimmed with a utility knife. Each corner of the receiving groove 6 is an arc, and the arc opening faces the center of symmetry of the base 3. The depth of the receiving groove 6 is the same as or slightly greater than the thickness of the aluminum plate 2. In this embodiment, the depth of the receiving groove 6 is 2.5 mm and the thickness of the aluminum plate 2 is 2 mm.

[0018] Limiting pins 5 are used to precisely position the aluminum plate 2 placed on the base 3, restricting its horizontal movement. The pressure plate 1 is placed on top of the positioned aluminum plate 2 to press it down during the trimming process, preventing it from moving or warping and providing a stable base for the trimming operation. The shape and position of the pressure plate 1 correspond to the rubber 9 area on the aluminum plate 2 that needs trimming, providing ample operating space for the trimming tools and avoiding interference.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
