Service HotlineIn order to effectively improve the working efficiency of bearing installation when the equipment or device is being installed with flat pads, it is necessary to arrange the positions of the front and back of the flat pad.エ Time-consuming, labor-intensive, low production efficiency, high processing cost defects, at the same time, there is a shortage of unstable product quality, so the development of a flat pad front identification feeding mechanism has become a hot spot of industry research.
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.
The retaining ring is divided into two types: shaft use and hole use. Its structural characteristics: The shaft retaining ring is a kind of retaining ring installed on the shaft groove, which is used for positioning and fixing of shaft end parts, and can withstand severe vibration and shock loads, but It is necessary to take anti-loosening measures and installation positioning; the hole is installed in the circular hole with an elastic retaining ring, which is used for the axial movement of the fixed parts. The outer diameter of this retaining ring is slightly larger than the diameter of the assembly circular hole.
At present, injection molding screws are widely used in various electronic and automotive components, including a body, the middle of which is provided with a through hole 3, the body head 1 has a hexagonal cross-section, and the tail 2 is provided with screw teeth. When in use, the middle through hole 3 of the main body will first put the wire harness, and then fix it by injection molding from the head I, and the threads of the tail 11 should be connected and installed with other components. Because the head I of the main body is hexagonal, the torque provided after injection molding is insufficient. Therefore, after the external thread is installed and connected with other components, the head is prone to slip, the installation is not reliable, and there is no push-pull force, resulting in product failure and increased safety hazards.
Stainless steel fastener product size standards: specify the content of the basic size of the product; threaded products. Not the standard in terms of product technical conditions. Specifically, it includes the following standards: Standard for fastener product tolerance: specifies the content of product size tolerance and geometric tolerance. Standards for mechanical properties of fastener products: specify the marking method of product mechanical property grades, as well as the content of mechanical property items and requirements; some fastener products change this content to product material properties or work performance. content. Standards for surface defects of fastener products: specify the types of surface defects and specific requirements of products. Surface treatment standards for fastener products: specify the types and specific requirements of product surface treatment. Fastener product test standards: specify the test content of the above-mentioned various performance requirements. Standards for product acceptance inspection, marking and packaging of stainless steel fasteners: Standards for fastener product marking methods: specify the content of complete product marking methods and simplified marking methods. Other standards for stainless steel fasteners: such as fastener terminology standards, fastener product weight standards, etc.
