The wire rolling machine is mainly suitable for cold rolling forming. The cold rolling process is a chip free processing process, which uses rolling tools to knead and form. Rolling metal fibers are connected. Rolling is the radial pressure generated, which can effectively improve the finish, hardness and strength of the workpiece surface, improve the operation efficiency several times or even dozens of times than chip processing, and then save materials more and realize automatic processing more easily.
The machine tool can roll, straighten, roll smooth, shrink diameter and various forming and rolling of general thread, twill, straight thread, oblique tooth, trapezoidal thread and modular thread under the cold state of its rolling range. The machine tool has a safe and reliable electrical and hydraulic performance and control organization. The rolling operation cycle can be selected between manual and automatic (users can provide their own rollers according to their needs).
The rolling tool has strong specificity and is suitable for rolling workpiece. The material hardness is not higher than HRC25 * below hrc20, the elongation shall be greater than 15%, and the tensile strength shall be less than 60kgf / mm2. With the increase of material hardness, the service life of the rolling tool decreases sharply.
Treatment method of abnormal sound produced by wire rolling machine during operation
When using the wire rolling machine, what should I do if I make an abnormal sound during operation? Don't worry, here's your advice: during normal operation, the wire rolling machine sometimes makes abnormal sound. The main reason should be that the oil temperature is too high! In addition, maybe the oil return pipe is higher than the oil level, and the oil and oil tank are too dirty. The planning time of the oil return pipe is a little small, which is not a big problem. It is advocated to clean the hydraulic system and oil of the wire rolling machine and replace it with new oil, so that the problem of the wire rolling machine can be solved.
What should we pay attention to before the operation of screw thread rolling machine? Please see the following instructions:
1. The diameter reducing machine tool must be well grounded, and the conductor shall not be less than 4mm2 copper flexible wire. It is not allowed to connect the power supply voltage exceeding the specified range, plug in and unplug the plug-in with power, and test the control circuit with a megger, otherwise the device may be damaged.
2. When inserting and unplugging connectors, do not pull wires or cables to prevent welding and pulling off.
3. Close to switches, encoders, etc. do not touch with hard objects.
4. Do not touch the display unit with sharp objects.
