Service HotlineDue to the high demand for electronic products and the reduction of assembly line workers, in order to cope with the problem of labor shortage, manufacturing factories need to use automatic screw locking equipment to replace manual labor. In the existing automatic locking and paying equipment, most of them use a screw arranging machine to arrange the screws, and an electric screwdriver (electric batch) takes the screws back and forth, or the special equipment blows the screws into the electric batch to send the screws to the electric batch, and back and forth. The method of taking is too time-consuming, and the method of blowing air is not suitable for screws with small aspect ratios.
Knurled copper nut, the specification is M5X8X12, the outer circle is 8.0MM, and the height is 12MM. Material: C3604 (ROHS PASS) brass. The thread still guarantees 6H accuracy. This knurled copper nut is used in power tools. Unlike other knurled copper nuts, the diamond pattern of this knurled copper nut is located in the middle of the product, and the diamond-shaped mesh knurled wheel edge The large outer circular step surface is rolled out of diamond-shaped flowers.
Drilling screw is a new invention of people in recent years. A screw is a common term for fasteners, an everyday colloquial language. The tail of the drill tail screw is in the shape of a drill tail or a pointed tail, and no auxiliary processing is required. Drilling, tapping and locking can be directly carried out on the setting material and basic material, which greatly saves construction time. Compared with ordinary screws, its toughness and pull-out force and maintenance force are high, and it will not loosen for a long time after combination. It is easy to use safe drilling and tapping in one operation. Drill tail screw Drill tail screw use: It is a kind of screw, mainly used in the fixing of color steel tiles of steel structures, and can also be used for thin plate fixing of simple buildings. It cannot be used for metal-to-metal bonding. Materials and models The materials are iron and stainless steel, of which stainless steel is divided into various materials. Models are: Φ4.2/ Φ4.8/ Φ5.5/ Φ6.3mm, the specific length can be agreed upon request. According to the different drill tails, it can be divided into: round head rice / cross / plum blossom, countersunk head (flat head) / rice seed / cross / plum blossom, hexagonal washer, round head washer (big flat head), horn head, etc.
The square nut is a fastener that needs to be used in the installation of the cable tray. In the prior art, the square nut 1 is pressed by the elastic force of the spring 2 below it and the opening of the C-shaped steel 3 (as shown in Figure 1, Figure 2), in the absence of external force, through the interaction of pressure and static friction, the C-shaped steel 3 will not move vertically or horizontally, which can facilitate engineering installation. The advantage of this installation method is that it can slide anywhere on the C-shaped steel 3, but the disadvantage is that it occupies the bottom space of the C-shaped steel 3, and the spring 2 will interfere with the installation hole of the square nut I, which affects the installation.
As a special kind of rivet parts, the rivets for shrinking brake pads are used in the accessories of the automobile industry. The original brake pad rivets do not have a chamfered structure, so the materials cannot be normally fed during assembly, or there are burrs, which lead to unqualified batches. When improving this structure, many manufacturers in the same industry often solve the problem by machining chamfering, but for brake pad rivets with thin thickness, it is impossible to achieve the problem of beating and bad material after chamfering processing.
