Service HotlineIn another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35 , and the screws enter the screw accommodating hole 43 from the discharge port through the guide rail 6 . The slotting is carried out, which improves the efficiency and saves the labor cost.
The main purpose of the embedded nut is to replace the direct opening of screw holes on the injection molded parts, so as to improve the strength of the screw holes of the injection molded parts. Referring to FIG. 1 , in order to lock the workpiece 3 ′ on the injection molded part 2 ′, the screw 5 ′ passes through the through hole on the workpiece 3 ′ and is screwed into the screw hole of the embedded nut 1 ′ to fix the workpiece 3 ′. The embedding between the embedded nut 1' and the injection-molded part 2' generally includes two ways. One is to heat the embedded nut 1' and then insert it into the injection-molded part 2' by hot pressing; the other is to insert the embedded nut into the injection-molded part 2'. 1' and the injection part 2' are integrally injection-molded. In order to ensure the bonding strength between the inner nut 1' and the injection molded part 2', knurling is provided on the outer peripheral surface of the inner nut 1'.
Two-combination screw refers to a screw and a flat washer, or a spring washer, or a square washer, or a two-piece combination with an external tooth lock washer. Then there are all the standard types of two combination screws! The following is a brief introduction: 1. The second combination screw with spring washer refers to the combination screw with a spring washer. The spring washer is a spring washer specially used for combination screws, not the ordinary spring washer that we usually use. 2. The two-combination screw of the trim pad refers to the combination screw of the screw with a flat pad. The size of the flat pad and the thickness of the flat pad can be customized. Can be customized according to customer requirements. Flat pads are punched out by punching machines. 3. The combination screw with two external teeth refers to the screw with an external tooth combination screw. Many customers, especially electric power customers, use this external tooth two combination screw to break the paint and make the screws on the iron plate. All can be powered on. 4. Two combination screws with a square pad refer to a square pad with a square pressure line for the screw. This square pad crimping two combination screw is used on the terminal, and the function is used for crimping and wiring.
A screw belt structure, especially a screw belt that can position the screws on the screw belt, so that the screws do not swing, so that the screws can be stably aligned with the points where the screws are to be screwed, and the screw fixation of the screws is facilitated. In its overall implementation and use, the innovative design of the screw belt structure increases the practical function characteristics.
Spring washers are widely used in the load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and easy installation. They are suitable for parts with frequent assembly and disassembly. Quick and easy automatic selection of washers is included, but the anti-loosening ability of spring washers is very low! Especially in European and American countries that require high reliability, the adoption rate is extremely low, especially the important load-bearing structural connection parts have long been abandoned. Our country still has some applications in the military industry, but it has been improved to stainless steel. Steel spring washers have long been banned in CASC! It is also said to be very unsafe, because there are two reasons: 1 is circle rise and 2 is hydrogen embrittlement.
