Fuzhou three and positioning pin products okay?
The function of the positioning pin is to limit the freedom of movement of the object. This degree of freedom means that the object must have six degrees of freedom in space, with linear motion in the X, Y, and Z axes and rotational motion around the X, Y, and Z axes. It has no fixing effect and can be removed after installation.
Then, in a mold composed of two or more parts, the pin is widely used in a mold, including a press mold, an injection mold, etc. In addition, stamping molds and injection molds have very high requirements for accuracy. It is not enough to fix the template with bolts, so only positioning pins can be used for positioning.
or prevent wrong installation position and orientation. In addition, pins have some applications in many mechanical motion devices, which are mainly used to determine position based on two-dimensional space.
There are five types of pins: fixed, replaceable, tapered, chamfered and standard diamond. Typically, such parts are sold point-to-point. Positioning pin standards include cylindrical pin GB.T119.1-2000, GB/T119.2-2000, internal thread cylindrical pin GB/T120.1-2000, GB/T120.2-2000 and tapered pin GB/T117-2000.
The size of the positioning pin is 3~50mm fixed pin, etc. Since the pin needs to be clamped repeatedly during use, the pin shaft is required to have better wear resistance, so the better material should be T10A or 20# steel. The technical requirements of the material include blunt corners, anti-rust treatment, heat treatment, etc.
The positioning pin has a good positioning effect and is very convenient to install. The bottom and lid are positioned with tapered pins and fixed with bolts, which makes it very easy to open the lid.
There are 3 to 50mm fixing pins, and so on. Since the pin needs to be clamped repeatedly during use, the pin is required to have good wear resistance, so the better material should be T10A or 20# steel. The technical requirements of the material include blunt corners, anti-rust treatment, heat treatment, etc.
Sanhe positioning pin positioning effect is very good, the installation is very convenient. The positions of the box seat and the box cover are fixed with pins and bolts, and it is very convenient to open the box cover.
It should be noted that when the mold is closed, the mold must be properly synchronized to make a perfect product, and the pin can help the upper and lower molds to be positioned in a precise position, thereby ensuring the quality of the product.
However, each type of part requires careful care and maintenance, so when purchasing such positioning parts, the purchaser must pay attention to the storage conditions and instructions of the parts to ensure the correct use of each positioning pin.
or prevent wrong installation position and orientation. In addition, pins have some applications in many mechanical motion devices, which are mainly used to determine position based on two-dimensional space.
