What special tools must be used for blind rivets? 1. Drill out the core of the blind rivet with a hand drill; 2. If there is no hand drill, a hand grinding wheel will do; 3. If neither of the two is available, you can use a file to file the bolt head. If it is thinner, use a nail to drive it in; 4. If there is none, you can only use a small carpenter's chisel like a flat-blade screwdriver to chisel off the bolt head or chisel it higher and then unscrew it with needle-nose pliers.

Pull rivets extend the service life of pull rivets. Pull rivets not only maintain the advantages of cold rivet bolts such as low equipment labor efficiency, low noise, and fuel saving, but also ensure the high toughness of the pultrusion deformation riveting during use to permanently build the connection and prevent loosening. , anti-corrosion to extend the service life. And the reaction force bites the core of the rivet. The core is under pressure, which will drive the soft rivet head to expand outward into a boss shape, so that the material can be closely integrated. Apply tensile force again until the nail core is broken, and then the board can be riveted.

Several types of inspections should be made when inspecting finished rivets: rivet body diameter, rivet body rod length, rivet body cap thickness and cap diameter, nail core length, nail core exposure size, screw The size of the nail and the diameter after installation can all be taken into consideration. During the actual inspection, the weak points of the product can be measured, such as tensile strength, shear resistance, open blind rivets and the anti-hair loss strength of the nail core. It is important to pay attention to whether the bolts are riveted enough and whether they are riveted in time; or the sun visor of the nail core is so large that the branch pipe of the rivet body cannot be pulled off; there is also a skip head, that is, the breaking force of the nail core is too low or it is broken. Specifications are too detailed, etc.

Where do blind rivets need to be used?

Proper care and maintenance of rivets can extend the life of rivets. Rivets should be wiped with unsalted butter once a month to lubricate and rust-proof them. Assembly and disassembly should be done frequently, especially when disassembling and assembling rivet heads. If you are reckless, you should turn the rivet head and pull it out slowly and hard. If the rivet seat for inserting the rivet head is pulled out of the normal position, the position of the rivet head will be significantly different after the core-blown rivet rivet is installed. Sticker The bolt riveting process has the characteristics of quietness, no impact, smooth material deformation, and good appearance. The process uses a motor, a spline shaft, etc. to drive the spindle bearing, and then completes the rotation of the rolling riveting head with 2 or more 3 rollers, the rollers can rotate around their axes, the appearance and related regulations require special design, ball screws, rails, servo motors control the vertical movement of the spindle bearing box, and the inspection module is used to inspect the ball pins The pendulum power is controlled by a fuzzy control method, the speed of the work is adjusted, and then the comprehensive control of the pendulum power\/torque and riveting cycle time is achieved.

Rivet manufacturers need to prepare some tools to install bolts: bolts, 3mm round hole punch and bolt mold. Common bolt operation procedures: 1. On the surface that needs to be fixed , use a round hole punch to make a hole from the front 2. Place the long nail of the bolt on the base 3. Put the items that must be bound on the long nail 4. Modify a short cap on the exposed long nail 5. Point the bolt mold to the short cap, tap the mold with a hammer, and pay attention to the width to ensure that it is in place in one step.
