Service Hotlinedouble-headed pin puller includes a slider hammer and a sliding rod, two ends of the sliding rod are respectively provided with different types of pin-pulling parts, the pin-pulling parts are threadedly connected with the sliding rod, and the sliding rod is also provided with There is a sliding rod limit block, and the sliding rod is slidably connected with the slider hammer. The double-headed pin puller can install two types of pin-pulling heads at the same time, and can pull out two different types of pins. It is easy to use and has high work efficiency. Disadvantage: Single function, cannot be used to install pins.
Therefore, in some cases, workers use a fixed torque wrench to control the tightening degree of the nut, but the fixed torque wrench is not convenient to use, and it needs to be checked frequently. At the same time, because the fixed torque wrench is not a conventional tool, its price is relatively high, which It also leads to its high procurement cost, and frequent verification also makes the later use cost also high.
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.
At present, in the process of injection molding, stamping, testing, etc., the product is usually positioned on the mounting plate or the positioning plate by pins. The general pin positioning method uses cylindrical pins with the same cross-sectional diameter for positioning. Because the product is easily deformed during processing, the pin positioning hole on the product is also deformed. With this kind of pin for positioning, the pin is often stuck. Dead products cause inconvenience in handling the workpiece, resulting in broken pins or scratched or even damaged products, with obvious defects.
The rod end of the ceramic production equipment is installed with the rod shaft, and then fixed by the cylindrical pin. At present, it is purely manual installation. It is impossible to ensure that the cylindrical pin is kept horizontal during the installation process, and the installation pressure of the cylindrical pin cannot be sensed. The pressure is too large. Cracks in the rollers, too low pressure, and easy loosening of the metal cap; it is impossible to install three or more cylindrical pins at the same time, and it is difficult to align the cylindrical pins with the pin holes of the cylindrical pins, resulting in low efficiency.
