1,Profiles of product:
High-precision brazed welded frame is the best welding frame made in China with the convenient operation,high precision and low-cost.The STCV is of the same precision with the one from ITALY and GERMANY,But STCV cost is only 20%-30% of the one from ITALY and GERMANY.
STCV may get the high welded precision of Diamond Blade and reduce extremely the procedure of sharpening the segment.
2,Structure of welded frame:
A)main body fram
B)electrical control (or manual-control) steel blank suspending adjusting system.
C)pneumatic steel blank slots self-indexing distance automatically positioned system with water cooling.
D)manual segments clearence adjusting system.
E)steel blank air cooling system for welding area.
F)electrical control system
3,major spec.:
A,)Diameter of diamond blade:
250~1000mm(type I ), 250~2000mm(type II),
B,)speed of welding:
15~20 seconds per tooth (3~4 piece of segments per minute for dia.350mm blade segment).
C, )surface tolerance=±0.05;
D, )clearence difference=±0.05;
4,Necessary Accessory
a)high frequency welding machine(GP—15kw or GP---25kw)
b) Air compressor
c) water pump(100W—120W)
The accessory may be supplied with the frame,but the additional cost be added.
5,Installation material:
a) 3 phase 4 wired cable copper lead :4 mm2
b) Rubber anti-pressure water pipe:Dia.10mm
c) Rubber anti-pressure air pipe:Dia.8mm



Brief Operating Introduction

1. Frame installing
Tear down outside packing for frame carefully, check if parts are broken due to the shipment. Install the frame in the firmly actinic groundsill which has already floored, use anchor bolt if possible.

2. high frequency welding machine installing
Install the welding machine in the welder splint (No.1 in picture), fasten it if needed.

3. Circle water pipeline installing
Pipe the cooling water into the place where frame and welded machine at, outing hydraulic pressure between 0.3 to 0.6Kgf/cm2, install back water pipe.

4. Compressed air installing
Install compassed air in the windpipe on frame, systemic pressure 6Kgf/cm2.

5. Power supply connection
Connect the welding machine, air compressor and water pump to the eligible power supply switch, frame connect with floor, check if electrical connection insulation is OK.

6. Adjusting before welding
Before using the frame, check the fastness of each immovable parts, adjusting clearance between each moving parts(especially segment alignment slipper block (No.2 in picture)),height of welded head, forward and backward position, segment up and down handle (No.4 in picture) elasticity.

7. Welding operating

1. install the blade in the blade clamp plate (No.5 in picture).
2. Life the blade to the welding height use the blade up and down switch (No.6 in picture).
3. Pull blade clamp handle (No.7 in picture), clamp the blade.
4. Pull segment lock handle (No.8 in picture), nip the segment on segment clamp (No.9 in picture) .
5. Loosen lock button (No.10 in picture), adjust alignment adjuster (No.11 in picture), and make the segment two edges symmetrical when segments connects the body.
6. Pull blade clamp handle (No.7 in picture), loosen the blade. Adjust blade segment localizer (No.12 in picture), adjust the welded position.
7. Pull blade clamp handle (No.7 in picture), clamp the blade. Wipe welding liquid on the body and put the silver solder, lower the segment up and down handle (No.4 in picture) to make the segment stick on the blade, switch on the welding machine starting to weld(welding time depending on the thickness of the segment).
8. Pull blade clamp handle (No.7 in picture), loosen the blade. Measuring the symmetrical between segment two edge.
9. According to the frame provided micrometer gauge, fine adjust the symmetrical once again after step 8 checking.
10. Repeat step 2 to 9, till welded segments and body symmetrical, then can proceed with the production welding.

8. Daily care
Clean the dirt on each part everyday, inject 20# or 40# lubricating oil into the parts that needed.
