The utility model provides a cutting device's effect is treated the cutting tubular product and is cut, obtains solitary wheel rim.

As shown in fig. 1, the utility model discloses an annular rim brace table 1 of fixed setting, a plurality of rim fixture 2 along the even setting of annular rim brace table to and be used for the cutting mechanism of cutting waiting to cut tubular product 3.

The annular wheel rim supporting table is used for supporting a pipe to be cut, the pipe is clamped by the wheel rim clamping mechanisms, and the pipe is longitudinally cut by the cutting mechanism.

As shown in fig. 2 and 3, the rim clamping mechanism comprises a fixed support 4, a first support rod 5 of the support is fixedly connected with a clamping cylinder 6 of the support, a second support rod 7 connected with the movable end of the clamping cylinder, and clamping rollers arranged at the tail ends of the first support rod and the second support rod respectively, the clamping rollers comprise a roller body 8 and a driving motor 9, and shaft heads of the roller body are fixedly connected with output shafts of the driving motor.

The axle centers of two ends of the roller body of the clamping roller respectively extend out of the axle heads, and the axle heads are connected with an output shaft of the driving motor through a coupling. The driving motor can drive the clamping rollers to rotate, and when a plurality of clamping rollers clamp the pipe to be cut, the pipe to be cut can be driven to rotate through synchronous rotation of the plurality of driving motors so as to adjust the cutting position.

When the wheel rim clamping mechanism is used, the initial positions of the two clamping rollers of the wheel rim clamping mechanism are shown in fig. 2, wherein the clamping cylinder drives one clamping roller to be far away from the other clamping roller, the annular wheel rim supporting table can be arranged close to the tail end of the first supporting rod, so that a pipe to be cut is placed on the annular wheel rim supporting table, the pipe to be cut is close to one clamping roller, then the clamping cylinder drives the clamping roller far away from the pipe to be cut to move towards the other clamping roller until the two clamping rollers clamp the pipe to be cut, and at the moment, the positions of the two clamping rollers can be shown in fig. 3.
