Internal Thread Drawbench Technology Parameters
Internal thread drawing is the process of forming an external thread on the surface of a wire or other rod-shaped metal object. A die is used to perform the operation. It is a cold extrusion process that requires precision sizing. Different materials can be extruded with different thread forms to produce parts. In general, the internal thread drawing process is done by a combination of two different operations, drawing and forming. This process is used to make products such as automotive fuel pumps and bicycle gears.
The internal thread drawing process typically consists of two sets of tools and dies. The first set is called a draw bench, which is used to draw the wire through a die to form the thread. The second set of tools is called roll sets, which are used to roll the threads onto the surface of the wire or rod. The combination of draw benches and roll sets allows for a more precise thread forming process.
The draw bench is the most important part of the internal thread drawing process. It is made up of an assembly that includes a sturdy die holder, an adjustable speed gear box, and a drive to power the system. The die holder is secured onto the draw bench, and then the wire is fed through the die. The adjustable speed gear box then allows the operator to adjust the speed of the machine to match the desired thread depth. The feed rate can be adjusted to ensure a consistent finished product.
The second part of the thread drawing process involves the use of the roll sets. A roll set is an assembly of dies and punches that allow the operator to customize the shape and size of the thread. The proper roll set will vary depending on the desired application of the thread. The roll sets can be used to create a wide variety of thread forms, such as straight, buttress, and wave forms.
Internal thread drawing is an important process in the manufacturing industry. It is used in many applications and is a reliable, repeatable process. The combination of draw benches and roll sets allows for greater flexibility and accuracy, making it an ideal option for many manufacturers.
In order to improve the internal thread drawbench process, several key parameters must be considered. The first parameter is the size and type of the thread, which will determine the size of the drawbench and roll sets needed. The second parameter is the speed of the drawbench, which should be set to match the desired depth of the thread. The third parameter is the type and size of the roll sets, as they must correspond to the thread being drawn. Finally, the fourth parameter is the drawbench drive, which should be set to match the type of material being extruded.
Once these parameters are established, the quality of the threads produced will increase, resulting in higher product yield, lower costs, and increased quality of the finished product. Through the use of modern technology and precise settings, the internal thread drawing process is becoming increasingly precise and efficient, allowing manufacturers to produce higher quality products.
