Service Hotlinerotating rod is rotatably installed on one side of the two pillars that are close to each other, and a second bevel gear is welded on the ends of the two rotating rods that are close to each other. The two second bevel gears are meshed with the two first bevel gears respectively. , The first sprocket is welded on the two rotating rods, the chain is meshed on the two first sprockets, and the screw rods are installed on the sides of the two pillars that are close to each other. Above the rod, the second sprockets are welded on the two screw rods, the two second sprockets are connected to the two first sprockets through two chains respectively, and threaded blocks are threaded on the two screw rods. The sides of the two threaded blocks close to each other are symmetrically welded with connecting columns, and the sides of the four connecting columns close to each other are welded with movable rods respectively. The other ends of the support plates are respectively rotatably installed with the same support plate, and the assembly device body is fixedly installed on the top of the support plate.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a new type of open blind rivet suitable for riveting of aluminum Al, steel St, and stainless steel SST sheets with foam material in the middle. The new rivet improves the mandrel process, adopts aluminum mandrel, the head of the mandrel has a pit for easy deformation, and there is a conical stop groove above the breakpoint of the mandrel. The mandrel can be caught by the stopper to prevent the nail head from being exposed. At the same time, lock the core rod not to loosen.
As the preferred embodiment of the above-mentioned embodiment, the motor 41 is provided with a thruster 46 that moves the cutting wheel 42 toward the conveying device 3. When the screw needs to be slotted, the thruster 46 generates a thrust toward the screw, and the motor 41 generates a thrust in the direction of the screw. Under the action, the groove is moved along the track 47 toward the screw. The other end of the motor 41 is provided with a bearing 45, and the output end of the motor is provided with a special-shaped wheel 44. The special-shaped wheel 44 is geared to the bearing 45. The wheel 42 is close to or away from the conveying device 3. When the grooving is completed, the special-shaped wheel 44 rotates and drives the bearing 45 to generate the opposite force from the above-mentioned thrust, so that the motor 41 moves back to the original position along the track 52.
Blind rivets (blind rivets) --------- rivet body (rivet body) mandrel (rivet stem or rivet mandrel). It is a type of rivet for single-sided riveting, but it must be riveted with a special tool - a rivet gun (manual, electric, pneumatic). When riveting, the rivet core is pulled by a special rivet gun to expand the rivet body and play a riveting role. This type of rivet is especially suitable for riveting occasions where it is inconvenient to use ordinary rivets (riveting from both sides), so it is widely used in construction, automobiles , ships, aircraft, machinery, electrical appliances, furniture and other products. Among them, the open-type oblate head blind rivets are the most widely used, the countersunk head blind rivets are suitable for riveting occasions where the surface needs to be smooth, and the closed blind rivets are suitable for riveting occasions that require high load and certain sealing performance.
With the continuous strengthening of infrastructure construction, the continuous increase of construction scale and the complexity of construction, the particularity of the requirements for construction equipment, materials, tools and equipment is also getting higher and higher, such as buildings, power stations, railway tunnels The channel steel used in these special construction environments requires the use of a special bolt, which must be easy to put in, easy to use
