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.
The pressure riveting nut is divided into free-cutting steel pressure riveting nut S type, stainless steel pressure riveting nut type CLS, stainless iron pressure riveting nut SP type and copper and aluminum pressure riveting nut CLA type, which should be used in different environments. . Sizes are usually from M2 to M12. There is no unified national standard for rivet nuts, and they are often used in chassis cabinets and sheet metal industries. S series, CLS series, SP series pressure riveting nuts use the internal thread as a simple method to install in precision sheet metal products, and use small and precise nuts for reliable fixing to completely process the side plate of the sheet metal. The nut is inserted into the hole of the metal plate, and the inlay strengthening function is completed by pressure. Application advantages 1. The back of the plate remains completely flat; 2. Small size and precision, suitable for all electronic or precision equipment; 3. High torque resistance; 4. Easy equipment, simple riveting; 5. Standardized serialization can meet various design requirements .
T-slot convenient bolt that can be used for the middle port of the T-slot and directly realizes the assembly and tightening of the bolt and the nut. Technical Background At present, the bolts for T-slots are assembled from two side ports of the T-slots. When the length of the T-slot is long, it is time-consuming and laborious to install from the side port to the center port at the designated position. In addition, the two side ports of the T-slot are often blocked by other components, and the bolts for the T-slot cannot be installed or removed without disassembling other components. The utility model makes some improvements to the prior art. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a T-slot convenient bolt with simple structure and convenient mounting and dismounting for the current situation that the existing T-slot bolts are inconvenient to install and disassemble.
The positioning pin is a pin designed to accurately position the two adjacent parts of the mold in a mold composed of two or more parts. It can be seen that the positioning pin plays a positioning role, and the mold must be accurately synchronized when it is closed. product, and the positioning pin can make the upper and lower molds play a role in accurate positioning. In the mold design and manufacture of Yueluo, the positioning pin is one of the most common parts. Since it is only used for positioning between parts, few people will pay too much attention to it. In the cold stamping process of Yueluo, the dimensional accuracy of the blanking parts depends on the size of the working part of the punch and the concave die, and the dimensional difference between them constitutes the blanking die gap. Gap is an important process parameter for die design, and its size has a great influence on the quality of the section of the blanking part, the blanking force, and the life of the die. If the gap is too large, punching burrs will appear in punching; if the gap is too small, secondary cracks will occur in the section and extrusion burrs will appear, which will make the quality of the section after punching unsatisfactory, and a reasonable gap will not only help the punching section. The improvement of the quality also contributes to the improvement of the lifespan of the 6-pack.
Bolts refer specifically to screws with larger diameters and may also have no heads, such as stud bolts. In general, it is not called a stud bolt but a stud stud. The most common form of stud is threaded at both ends and a polished rod in the middle. The most typical use: anchor bolts, or places similar to anchor bolts, thicker connections, when ordinary bolts cannot be used.
