In the case of the production of China used pipe mills, it is necessary to know the production process regulations of each equipment in order to operate the China used pipe mills according to the production process regulations.

The fifth step we first understand the flat head process of China used pipe mills

①Before work, first adjust the specific position of the flat blade according to the specifications and models of the processed steel pipe, replace the corresponding block specifications, and adjust the elevation position of the tooth plate of the walking beam. When installing the tool, you should pay attention to the height of the two milling cutters of each power head to the tool ground as much as possible. When installing, put the tool into the bayonet of the cutter head and lock it with screws. The radial direction should be determined according to the pipe diameter. When the position of the blade needs to be chamfered, adjust the installation angle of the cutter head according to the angle of the chamfer. It should be noted that: the radial position of the chamfering knife should be as accurate as possible, and the roundness of the steel pipe should be higher than the national standard. If necessary, a tool setting model should be used.

②Turn on the power head motor, manually feed, step up, push, step, etc., adjust the position of the power head to return to the set zero position. The position of the zero position is determined by the position of the proximity switch. There are two proximity switches on both sides of the zero position, as the limit position of the power head movement, which plays a protective role. After all actions are confirmed to be correct, manually move the two steel pipes to the pushing position and push them all the way. Pull the switch to the automatic state, and the working process will be carried out automatically at this time. It should be noted that if the parameters have not been tested after setting, it is best to manually complete a few working cycles to verify the practicability of the parameters. When the parameters are approved, it is best to record them for future use. . When the stepping mechanism rotates to send a signal, the solenoid valve of the clamping cylinder is opened, the steel pipe is clamped, and a signal is sent, the power head feeds, and the roller table is opened while clamping, and the steel pipe is pushed and pressed. The program decelerates and stops; when the power head is finished and quickly returns, the solenoid valve of the clamping cylinder changes direction and the clamping is released. For the sake of safety, the change of the proximity switch signal is used to detect the clamp return, and check whether it is returned. If it does not return to the original position, the following actions will not be performed. After returning to the position, the stepping mechanism moves to move the flat-headed steel pipe to the next working position or out, and at the same time move the steel pipe to be processed to the working position, and then perform the flat-head cycle operation according to the above procedure.

After learning the flat head process, you can perform the actual operation principle of the steel pipe of China used pipe mills according to the flat head process.
