Open Type Pop Rivet for Blind Installation

When Wanluo Factory was manufacturing Open Type Pop Rivets for Blind Installation, it adopted the core shaft stretching and expansion locking principle. By breaking the core shaft, the tail of the rivet was evenly expanded and tightly adhered to the hole wall of the sheet material, forming a flat, highly adherent, and non-detachable permanent connection structure. The overall construction is simple, the assembly speed is fast, and it does not cause compression damage to the sheet surface. It is suitable for the splicing and fixation of various metal sheets, sheet metal components, and thin profiles. It is a universal and efficient fastener for modern light industry assembly, lightweight equipment assembly, and sealed structure fixation.

Actual performance tests

1. Single-side riveting forming test

This test simulates common blind holes and closed-layer conditions in industrial settings and conducts batch riveting tests. The entire process can be completed with only single-side tool operation, resulting in uniform expansion of the nail body, no warping or hanging gaps on the panel surface, a full and regular back formation, and perfectly solving the problem that traditional fasteners cannot be installed on the back. The forming qualification rate is stable and meets the industrial standards for thin plate fixation, equipment shell assembly, and cabinet assembly.

2. Tensile and shear bearing capacity test

Our Open Type Pop Rivet for Blind Installation undergoes static load tests using a universal testing machine. After riveting and forming, it can withstand standard lateral shear force and longitudinal tension. After being subjected to force, there will be no loosening, disconnection, or separation of the board. The overall connection strength fully meets the industrial standards for thin plate fixation, equipment shell assembly, and cabinet assembly.

3. High-frequency vibration anti-loosening test

This test is conducted using an industrial vibration test bench for continuous vibration testing, simulating equipment operation and vehicle jolting conditions. After long-term and high-frequency vibration, the riveting points do not loosen, do not shift, and the nail body does not fall off. The connection stability is superior to that of ordinary screws with single-sided locking structure.

4. Board compatibility and compatibility test

Adaptability tests are conducted for different thicknesses of aluminum plates, steel plates, and stainless steel thin plates. The matching accuracy of the hole diameter is high. After riveting, the board surface is flat without bulging or cracking, and it will not damage the thin-walled workpiece structure. It is compatible with various light and precise assembly scenarios.

5. Batch construction stability test

Continuous 100 batch riveting tests were conducted. The nail body fracture force is uniform, and the forming consistency is high. There are no problems such as stuck nails, failure to pull through, or poor forming. It is compatible with factory assembly lines for rapid batch assembly, and the construction efficiency is stable.

Notes for Attention

1. Diameter matching requires standard specifications: During construction, holes must be drilled according to the specifications of the rivets. If the diameter is too large, it may cause excessive gap in the formed structure and loose connections. If the diameter is too small, it will lead to difficulties in riveting, abnormal nail body fracture, and affect the tightening strength.

2. Appropriate thickness of the matching plate: The corresponding length rivets should be selected based on the actual stacking thickness of the plate. It is prohibited to mix use of overly long or overly short specifications to avoid loose riveting or excessive opening at the tail end, and deformation of the plate.

3. Avoid using under excessive load conditions: The Open Type Pop Rivet for Blind Installation is mainly designed for thin plates, static, and light vibration assembly fixation. It is not recommended for use in core load-bearing structures with high strength, dynamic impact, and high-pressure force, to prevent detachment and failure due to long-term stress.

4. Keep construction tools in good condition: Use qualified pull riveting tools for operation. When the tool's jaws are worn or the pressure is insufficient, timely maintenance is required. Otherwise, it is easy to encounter problems such as inability to pull, deviation, and incomplete forming of the riveting.

5. Environmental compatibility based on material: For humid, outdoor, and acidic or alkaline environments, it is recommended to use rivets with corresponding anti-rust materials. Ordinary materials are prone to oxidation and rusting over time, gradually reducing the connection stability and affecting the overall service life of the equipment.

6. Prohibit secondary hammering or modification after forming: After the riveting is completed, it is prohibited to forcefully strike or twist the nail body, as this will damage the internal expansion locking structure, causing loose connections, reduced bearing capacity, and assembly hazards.

Product Parameter

Product Manufacturing Process

1. Unique single-sided blind installation function, no need for double-sided operation and reserved working space. It perfectly solves the fastening problem of closed, hidden and inaccessible structural parts, greatly expanding the scope of assembly application.
