Talking about the difference between local bending and global bending of the screw

Determine the bending position of the screw rod, whether it is local bending or overall bending, or a small amount of bending or a large amount of bending, and then you can decide whether to use manual straightening or use a press to straighten it. The use of a machine tool for providing an auxiliary support surface is essentially not necessary when the correction is carried out, since in practice the correction effect cannot be achieved in most cases when the lathe is used, mainly because the machine tool is being corrected. The basic method is flame or impact, which will affect the lead screw, mainly because this method will cause more severe centrifugal force when rotating.

The role of the positioning pin

The function of the positioning pin is to limit the degree of freedom of movement of the object. This degree of freedom means that the object must have six degrees of freedom in space, namely linear motion in the X,Y and Z axes and motion around X,Y,Z rotation. It has no fixed effect and can be deleted after installation. Then, in a mold composed of two or more parts, pins are widely used in the mold, including stamping molds, injection molds, etc. In addition, stamping dies and injection dies have very high precision requirements. It is not enough to fix the template with bolts, so only pins can be used to achieve the purpose of positioning

Structural classification of stainless steel shaft

Stainless steel shaft is widely used in engineering machinery, automobiles, motorcycles, packaging machinery, forklifts, etc. They are often used in harsh environments or in outdoor installations. Steel has better resistance to chemical corrosion and electrochemical corrosion, second only to titanium alloys. Heat resistance, high temperature resistance, low temperature resistance, and even ultra-low temperature resistance. It has high strength and hardness.

The screw: how to prevent screw deformation after heat treatment

The screw is characterized by high machining accuracy and strict deformation requirements. Due to the large number of machining procedures, the quality and deformation of heat treatment are very important. In production, it is found that the workpiece will be severely deformed after carburizing and quenching, and it is difficult to correct it. Large deformation also occurs during the processing after heat treatment, resulting in a large number of product repairs and many workpieces scrapped. In order to ensure the performance of its mechanism and facilitate users to perform secondary processing, usually only threaded parts are quenched and heat treated, while other parts can still be machined.

Characteristics of screw rod

Screw usually refers to the ball screw. The ball screw is an ideal product for converting rotary motion into linear motion, or converting linear motion into rotary motion. Screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or to convert torque into axial repetitive force. It also has the characteristics of high precision, reversibility and high efficiency. Because the friction resistance of the ball screw is small, it is widely used in various industrial equipment and precision instruments.
