What is the main aspect of blind rivets?

It is a type of rivet for single-sided riveting, but it must be riveted with a special tool - a riveting gun (manual, electric, pneumatic). When riveting, the rivet core is pulled by a special riveting gun to expand the riveting body and play a riveting role. This kind of rivet is especially suitable for riveting occasions where it is inconvenient to use ordinary rivets (riveting must be carried out from both sides), so they are widely used in construction, automobiles, ships, aircraft, machines, electrical appliances, furniture and other products.

Among them, open flat and round head blind rivets are the most widely used, countersunk blind rivets are suitable for riveting occasions that require smooth performance, and closed blind rivets are suitable for riveting occasions that require higher load and have certain sealing performance.

Hello! That's a really hard question for you! Blind rivets belong to a small category of fastener rivets in the hardware category, and the national standard is divided into.

GB12615 closed round head blind rivet;

GB12616 closed countersunk blind rivet, GB12617 open countersunk blind rivet;

GB12618 Open round head blind rivet.

Blind riveting finger nails are a type of rivets for single-sided riveting, but they must be riveted with a special tool - a riveting gun (manual, electric, pneumatic).

Key points of riveting: When riveting, the rivet is slowly matched with the nail core and pulled by a special riveting gun to expand the riveting body and play a riveting role. Among them, the open flat head blind rivet is the most widely used, the countersunk blind rivet is suitable for riveting occasions where the surface needs to be smooth, and the closed blind rivet is suitable for riveting occasions that require higher load and have certain sealing performance.

Hello, it is a pleasure to serve you and give you the following answers:1Reason:

The new blind rivets are not working well, either because the fasteners were not installed hard enough during installation, or because the bolts were installed away from the center of the installation, resulting in the blind rivets not being properly fastened together. 2.Workaround:

In order to install the blind rivet correctly, it is first necessary to ensure that the fastener is installed with sufficient force and that the fastener is installed in the correct center position. Secondly, the blind rivets can be lubricated with a lubricant, such as cellulite or grease, to reduce friction and make it easier to separate the blind rivets. 3.

Practice steps: (1) Check the installation strength of the fastener to ensure that the installation strength is sufficient; (2) Install the fastener in the correct center position; (3) Use lubricant to lubricate the inside of the blind rivet; (4) Using a wrench or screwdriver, gently loosen the blind rivet until it can be easily disassembled. 4.

Personal tip: When installing blind rivets, pay attention to the installation strength of the fasteners, ensure that the installation strength is sufficient, and the installation position of the fastening shed bright parts. In addition, when installing blind rivets, a lubricating chain friend can be used to reduce friction and make it easier to disassemble.

The opening size of the rivet hole is: min (min) + max (max) + the total thickness of the workpiece is generally 45%-65% of the rivet length, preferably not higher than 60%, the working length can not be too short to resist the base signs, usually 50%--60% shall prevail.

For example, if the total thickness of 2 or more workpieces is 6 mm, the rivet should be in length in mm.

Specifications are divided, diameter: ,, length has, 4--35mm (note that the small diameter can not be too long), the material is divided into: copper, iron, aluminum, stainless steel, 316 stainless steel, usually choose specifications and materials, it is necessary to come according to your plate thickness and tensile requirements, if you want to find detailed information, please find Guangzhou Hongmao hardware products ****, their business will help you answer one by one, samples are free!

There are many specifications, and the thickness is from about 5mm to 40mm.

The opening size of the rivet hole is: min (min) + max (max) +

The total thickness of the workpiece is generally 45%-65% of the rivet length, preferably not higher than 60%, and the working length should not be too short, usually 50%-60% shall prevail.

For example, if the total thickness of 2 or more workpieces is 6 mm, the rivet should be in length in mm.

The general use of rivets The opening size of the rivet hole is min (minimum) + max (maximum) + the total thickness of the workpiece is generally 45%-65% of the rivet lengthIt is better not to be higher than 60%.In addition, it is troublesome to work for a work length that is too short.

The recommendation is usually 50%-60%. For example, if the total thickness of 2 or more workpieces is 6 mm, then the rivet should be available in a length of mm

Summary. Belong. Pull rivet (pull rivet), the national standard is blind rivet, it is a kind of single-sided riveting, but must use a special tool - pull nail gun (manual, electric, pneumatic) riveting.

This kind of rivet is especially suitable for riveting occasions where it is inconvenient to use ordinary rivets (riveting must be carried out from both sides), Hengfeng rivets are widely used in containers, machinery, construction, automobiles, ships, aircraft, machines, electrical appliances, furniture and other products. Among them, the open flat head rivet is the most widely used, the countersunk head blind rivet is suitable for the riveting occasion that the performance needs to be smooth, and the closed blind rivet is suitable for the riveting occasion that requires a higher load and has a certain sealing performance. In stainless steel rivets, open round head rivets are widely used, mainly because the stainless steel rivet material has strong tensile and shear resistance, high hardness and strength, good quality, and the cost is much higher than that of aluminum rivets, and is widely used in riveting occasions with high requirements.

Belong. Pull rivet (pull rivet), the national standard is blind rivet, it is a kind of single-sided riveting, but must use a special tool - pull nail gun (manual, electric, pneumatic) riveting. This kind of rivet is especially suitable for the riveting occasion where it is inconvenient to use ordinary empty rivets (riveting must be carried out from both sides), Hengfeng rivets are widely used in containers, machinery, construction, automobiles, ships, aircraft, machines, electrical appliances, furniture and other products.

Among them, the open flat head rivet is the most widely used, the countersunk head blind rivet is suitable for the riveting occasion that the performance needs to be smooth, and the closed blind rivet is suitable for the bucket lack riveting occasion that requires a higher load and has a certain sealing performance. In stainless steel rivets, open round head rivets are the most widely used, mainly because the stainless steel rivet material lacks strong tensile strength and shear resistance, high hardness and strength, good quality, and the cost is much higher than that of aluminum rivets, and is widely used in riveting occasions with high requirements.

How big is the bottom hole of the countersunk rivet M4.

The diameter is 7 mm and the height is 4 mm. The counterbore diameter is millimeters, and the counterbore depth is millimeters. Countersunk screws, also known as countersunk screws, also known as flat machine screws, are a kind of construction parts.

The head is a 90-degree cone, similar to common wooden screws, and the head has tool tightening grooves, with a slot, cross, hexagon, and plum shapes. 2. The pitch of M4 is, M represents the ordinary thread, 4 represents the thread diameter Huai closed 4mm, and the screw bottom hole of M4 is. 3. The bolt sizes of M4 are M4x5, M4X10, M4X15, M4X20, M4X25, M4X30, M4X35, M4X40, etc.

4. Bolt M4 represents an ordinary thread, with a nominal diameter of 4mm and a pitch. Refer to the national standard: GB T196-2003 basic size of common thread.

5. The size of the M3 countersunk screw is the diameter of the screw head, the diameter of the counterbore, and the depth of the counterbore. 6. The size of the M4 countersunk screw ruler is the diameter of the counterbore hole and the depth of the counterbore.
