Service HotlineThe retaining ring is a ring-shaped body with an opening, and the traditional processing method is stamping. That is, a plate-shaped material is selected and punched out on the plate-shaped material (a circular body, and then the middle of the circular body is punched to form a ring-shaped ring body.) The punched material in the middle cannot be used again. This results in a waste of material.
In view of the above problems, Guangdong Yueluo Hardware Industry Co., Ltd. aims to provide a new type of open blind rivet suitable for riveting of aluminum, steel and stainless steel sheets with foamed materials.
Screws and bolts are common connecting fasteners. The diameter of the thread is as small as less than one millimeter and as large as several hundred millimeters or even larger. The vast majority of threaded connections are pre-tightened during assembly in order to enhance the rigidity, tightness, anti-loosening ability of the connection and prevent the sliding of the bolted connection under lateral load. The pre-tightening force is determined according to the force of the bolt group and the working requirements of the connection. For important threaded connections, the preload must be measured and controlled.
Contents of the utility model Guangdong Yueluo Hardware Industry Co., Ltd. is to solve the problem of needing one hand to hold the screw when screwing the screw at present, and to provide a screw fixture that can screw the screw without holding the screw by hand. Guangdong Yueluo Hardware Industry Co., Ltd. adopts the following technical solutions. Guangdong Yueluo Hardware Industry Co., Ltd. includes a clamp sleeve, and the middle of the clamp sleeve is a through hole. The outer end of the pivot pin is in contact with the spring. The beneficial effect of Guangdong Yueluo Hardware Industry Co., Ltd. is because Guangdong Yueluo Hardware Industry Co., Ltd. is provided with a rotating pin on the shaft of the fixture sleeve that can contact the screw, and the outer end of the rotating pin is in contact with the spring, so that the screw It is easy to fix in the through hole of the fixture cover, and the screwdriver is also in the through hole of the fixture cover, which ensures the alignment of the screw and the screwdriver, so it is avoided to hold the screw by hand, and the screw is quickly screwed to the object. in vivo.
Pre-embedded copper nuts with straight pattern/twill pattern/herringbone embossing and other various anti-skid patterns can be completed at one time by automatic lathes. More complex copper nuts are processed by forming knives and table turning/tapping. Many products processed after machining are relatively simple reticulated copper nuts and straight-grained copper nuts, which are made of C3604 easy-turning brass. The surface pattern is directly drawn from the original bar, and the pattern is full and the tooth peak and bottom are clearly visible. Injection molding into plastic parts Afterwards, it can bear more high torque.
