How to use the gasket of steel bar rolling mill

The gasket of steel bar rolling machine is divided into positive wire and negative wire. The number of the positive thread roller and the clearance direction of the gasket are clockwise, and the number of the negative thread roller and the clearance direction of the gasket are counterclockwise.

When installing, the gaskets should be installed clockwise around any eccentric shaft in the order of 7, 6 and 5, and the outer gaskets are 5, 6 and 7.

That is to say, the No.7 gasket corresponds to No.5, No.6 gasket corresponds to No.6 gasket, and No.5 gasket corresponds to No.7 gasket (the installation sequence of the reverse thread gasket is: 5, 6 and 7 for the inner gasket and 7, 6 and 5 for the outer gasket).

Matters needing attention in the use of thread rolling machine:

1, it is forbidden to thread without coolant.

3. The end of the steel bar to be processed should be flat and must be cut with a toothless saw. In addition, the end should be round and straight within 500mm length, and bending is not allowed. It is not allowed to directly process the end with gas cutting or steel bar cutting machine.

4, reducer should keep enough lubricating oil, observe the oil level from the oil mark, the distance between the bottom plane is about 1 15 mm, it usually takes 3-6 months to replace 46# mechanical oil.

5. The rolling machine should be maintained regularly, including cleaning the machine, adding grease, fastening screws everywhere and repairing damaged parts. , according to the general mechanical product maintenance procedures.
