2 Installation of bending mould

Loosen the nut on the bending mould, and install the required bending mould and tighten the nut

 

3 Installation of clamping mould

Loosen nut on clamping mould, install new clamping mould and adjust it as following:

A. Loosen the bolt fixed on the clamping mould, press the "Clamp" until clamping mould and inserts have a little space

B. Adjustment the height of the clamp mould, makes its center consistent with center of insert, and then tighten the fixing nut.

C. Press "Clamp", fasten the fixing nut on the clamping mould

D Press "- Clamp", clamping mould returns, and then rotate the fixing nut of clamping for 1/4-2/4circle, and fasten adjust nut

 

4. Installation of sliding mould

B. With push device, locate between the push and the slide groove. Fasten the adjusting nut on the push slide mould in the same as the clamp mould

 

5. Installation of mandrel cylinder

A. Revolve the mandrel into the mandrel bolt, adjust it to the right position, and then fix the mandrel and the nut.

B. Loosen the bolt of the oil cylinder of mandrel.

C. Move the finger on the seat of the cylinder of mandrel, to make it the same as radius of bending mould

D. Fasten up the screw on the base of mandrel cylinder

 

6. Installing of wiper mould

Install wiper mould on the wiper mould holder according to "Figure 7-1", and adjust about 1°-2 °.

 

 

1. Keep the machine and the ground clean and tidy.

2. The pressure of the machine can't surpass its extremity.

3. Lubricate the movable parts in time.

4. Keep the oil cooling facility work failure-free operation.

5. Check the height of the oil mark; it should be at 2/3 location of full range.

6. Use dry cloth to rub the machine after stopping it before getting off work.
