Trimmer Unit

Planning machine is special equipment of steel wheel production for removing and trimming welding slag generated by wheel rim welding so as to obtain flat welding seam surface. The machine is designed as automatically operation, it consists of host, hydraulic system and electric system, wherein hydraulic system and electric system are shared with rolling press machine and end cutting machine.

Lathe Bed

Host frame is C-type mechanism. The hydraulic driven clamp holder clamps two sides of welding seam.

Clamping Mechanism

Work piece is clamped and fixed by hydraulic clamping mechanism, and the mechanism is installed on the upward side of guide rail. The stop block is installed on clamping jaw to avoid axial loosening of work piece during slag planning.

The clamping mechanism is divided into two parts, the lower part of which is fixed on the lathe bed of frame, the upper part is movable and driven by oil cylinder.

Trimming Mechanism

Upper and lower slag planning cutter is installed on steel sliding frame. The sliding frame makes to-and-fro movement in the middle of clamp holder by support of guide rail after hardening treatment, and cutting surface of each cutter is set manually according to material thickness.

Cutting surface and clamp holder of slag planning cutter are connected by one set of mechanic mechanism to ensure its relative position. Therefore, whatever any material thickness, the machine will not set each time, and can cut material with difference thickness automatically.

Three cutters are installed on sliding frame, and lower clamp holder uses fixed-type, and is also used as guide rail of lower sliding frame. Movement of upper and lower cutters is driven by hydraulic cylinder.

Planisher Unit

The planishing machine is use to flatten and strengthen the trimmed welding-seam, the planisher's main parts includes machine, movable C-type frame, clamping device, rollers and hydraulic parts. C-type frame equipped with hydraulic drive system for rolling roller that fixed on the clamping mechanism.

C-type Frame

C-type frame fixed on the holder that can move along with the guide rail, it will be driven by oil cylinder. Holder can slide through roller bearing that set four (4) roller bearings each side. C-type frame's main function is to prevent rolling pressure skewing and the resulting rolling press size deviation.

 End Cutting Unit

Lathe Bed

C-type frame supports all major components and it is convenient for operation and adjustment.

Oil cylinder fixed on the top of the C-type frame which is used to drive the clamping and cutting mechanism, and it can be adjusted according to the width of rim band, the hand wheel adjusting mechanism mounted on the tail of frame.

Cutting Mechanism

Cutting mechanism cuts the both end of welding slag by cutting tool. The upper tool drives by high-pressure oil cylinder that stroke is 60 mm, upper tool (cutter) and lower tool (cutter) connects together by the linear guide pillar and guide sleeve. The front of the cutting tool (upper and lower) fixed on the upper and lower tool base, the back of the cutting tools installed on the movable slide base which can be adjusted according to workpiece width.

Cutting tools (cutter) made by tool steel, each pair cutter includes convex and concave shape tool, complete material cutting quickly. The clearance of upper and lower cutting tool should be 8-10% of the material thickness, for achieving the standard workpiece size at 0.2 mm.

NOTE: The clearance should be checked after cutting tool adjusting finished!

 Hand wheel Adjuster

Hand wheel adjuster can adjust the sliding seat position to adapt the width change of work pieces, including air cylinder, the tailstock and cutting tools, sliding seat can move horizontally by the hand wheel at the back of frame.

 Cooling Unit

The cooling unit is driven by the air pressure and designed as lever structure. Inside upper and lower cooling cooper band has cooling water circulation.
