1. Adjustment of thread rolling machine:
1. Debugging before processing
(1) According to the diameter of the steel bar to be processed, replace the thread rolling wheel that is suitable for the processing diameter.
(2) While replacing the thread rolling wheel, replace the washer that is suitable for the pitch of the thread rolling wheel to ensure the correctness of the pitch.
(3) After the thread rolling wheel is adapted to the processing diameter, insert the knife setting rod adapted to the steel bar into the center of the rolling head.
(4) Adjust the thread rolling wheel so that it is in contact with the knife setting rod, pull out the knife setting rod, tighten the screw, and press the ring gear so that it cannot move.
(5) For the equipment that fixes the positioning plate, according to the diameter of the processed steel bar, replace the positioning plate that is suitable for the processing diameter. The processing diameter is printed on the positioning plate.
(6) According to the specifications of the steel bars to be processed, adjust the position of the rib stripping stroke block to ensure that the rib stripping length reaches the required value.
2. Machine adjustment and installation
(1) Change the automatic and manual switch position of the electrical control box, and you can choose automatic or pedal rolling.
(2) Automatic cycle rolling: Turn the rolling button of the electrical control box to the automatic position, and the movable thread rolling shaft will reciprocate under the control of the time relay.
(3) Turn the rolling switch of the electrical control box to the manual position, and then press the manual rolling switch, and the movable thread rolling wheel can work.
(4) Unscrew the inner hexagon screw of the thread rolling shaft head cover of the threading machine, remove the front bearing seat of the thread rolling shaft to install the thread rolling wheel, and adjust the axial position of the thread rolling wheel with a spacer or fine adjustment.
2. The operation process of the thread rolling machine:
1. Turn on the power, open the cooling water valve, press the forward rotation start button, you can turn the feed handle, and feed in the direction of the workpiece to achieve cutting. When the rib stripping length meets the requirements, the rib stripping knife will automatically open and turn the handle Continue to feed to realize thread rolling. When the thread rolling wheel is in contact with the steel bar, force must be used to make the main shaft rotate one circle.
Axially feed a pitch length, when the feeding reaches a certain level, it can realize automatic feeding, until the whole rolling process is completed, it will automatically stop, and press the reverse start button to realize automatic retraction.
2. When the automatic knife retraction is finished, turn the feed handle clockwise to return the rolling head to the initial position, and the rib stripping knife will automatically reset at this time. Just unload the finished workpiece.
3. Use the ring gauge to check the thread length, if the error is within the range, it is qualified; at the same time, use the thread go-no-go gauge to check the size of the thread head.
4. When rolling anti-thread, first exchange any two positions of the thread rolling wheels in the rolling head; then exchange the position of the travel switch pressing block front and back, and ensure that the stroke remains unchanged.
5. When rolling the anti-thread, press the forward rotation start button, turn the feed handle to feed towards the workpiece to realize cutting, when the rib stripping length reaches the requirement, the rib stripping knife will automatically open and stop feeding, at this time press After the stop button stops, press the reverse button, the rolling head rotates in reverse, the joystick continues to feed, and the thread can be rolled.
When the thread rolling wheel is in contact with the steel bar, you must use force, and make the main shaft rotate a circle, and feed a pitch length axially. When the feed reaches a certain level, automatic feed can be realized until the entire rolling process is completed. parking. Press the forward rotation start button to realize automatic knife retraction.
