The thread pair has a 30° wedge-shaped inclined surface at the bottom of the female thread of the flange connection oil-resistant rubber expansion joint and the tooth tip of the male thread of the bolt, and the two corresponding wedge-shaped surfaces form an engagement. This meshing relationship makes the contact surface of the flange connection oil-resistant rubber expansion joint and the bolt change from a linear shape to a belt shape. The contact area and the contact stress are reduced, and the axial force of the external thread can be more maintained, thereby improving the anti-loosening ability of the entire fastening device. Various flange connection oil-resistant rubber expansion joints, or various expansion joint shells and aluminum, as well as various flange connection oil-resistant rubber expansion joints embedded, various cloth hot pressing, etc.
The temperature of the oil-resistant rubber expansion joint of the flange connection is adjustable, and the hot-pressing speed is also adjustable, which is mainly adjusted according to the product size and product thickness. Flanged oil-resistant rubber expansion joints have the advantages of simple operation, good effect of hot-pressed products, fast countersinking speed, and multiple flanged oil-resistant rubber expansion joints can be embedded at the same time. The flange connection oil-resistant rubber expansion joint is fast, and dozens of flange connection oil-resistant rubber expansion joints can be buried at the same time. After burying the flange connection oil-resistant rubber expansion joint, the product is very firm, beautiful in appearance, no glue, and no cracks. Open the cover and look for debris in the fuel tank between the punch rod and the die.
Flanged oil-resistant rubber expansion joints have been completely standardized in terms of structure, size, drawing, marking and other aspects. Mechanical parts and components with a high degree of standardization and strong industry versatility are also known as general-purpose parts. If the mold is loose, check that each part of the mold is secure and tight. The middle thread adopts the equidistant progressive flange connection oil-resistant rubber expansion joint full-thread type, the length-diameter ratio is greater than the length-diameter ratio of the small thread, the flange connection oil-resistant rubber expansion joint is equal from shallow to deep from root to root, and the flange connection oil-resistant rubber expands The smaller the joint, the larger the flange connection oil-resistant rubber expansion joint.
Flanged oil-resistant rubber expansion joint is a flange-connected oil-resistant rubber expansion joint that is suitable for flanged oil-resistant rubber expansion joints. The parts become a whole, and the metal is melted and mixed together at high temperature, and an alloy is added in the middle. The interior is the effect of molecular force, and the strength is generally greater than that of the parent body. The flange connection of the oil-resistant rubber expansion joint at the end of the flange connection is deeper, and the flange connection of the oil-resistant rubber expansion joint at the root is shallow, and the extrusion volume of the expansion joint is large, which does not affect the strength of the screw. The extrusion speed is fast and the plasticization is good. It is an ideal screw for the production of thermal insulation layers and sheath layers in general small and medium-sized extruders.
