Abstract

The invention discloses a guide roller structure of a multi-thread cutter. When used on large-scaled machines, the guide roller structure has small guide rail inertia and high system control performance, needs no drive from a large-capacity guide rail driving motor and reduces device cost. The guide roller structure comprises a conduit, bearing seats and outer circular surfaces of guide rollers, wherein the conduit is supported on the bearing seats on the two ends; and the outer circular surfaces of the bearing seats are sleeved with the outer circular surfaces of the guide rollers. The guide roller structure is characterized in that: each of the outer circular surfaces of the guide rollers comprises an internal steel tube, a middle carbon fiber composite layer and an external polyurethane layer, wherein the internal steel tube is sleeved on the outer circular surfaces of the bearing seats; the middle carbon fiber composite layer covers the outer circular surfaces of the internal steel tubes; and the external polyurethane layer covers the outer circular surface of the middle carbon fiber composite layer.

Description

The deflector roll structure of multi-line cutting machine

Technical field

The present invention relates to the technical field of multi-line cutting machine structure, be specially the deflector roll structure of multi-line cutting machine.

Background technology

The critical piece structure of the deflector roll of existing multi-line cutting machine is a full steel structure, and it is still no problem that the full steel structure deflector roll is applied on the little processing specification lathe, and rigidity is better, and inertia also can be accepted.But in the time of on being used in big processing specification lathe, the necessary corresponding increasing of deflector roll appearance and size is to guarantee rigidity, and other sizes such as wall thickness equally must corresponding increasing.Deflector roll inertia increases sharply by the cube of processing specification, and system control performance significantly descends, and needs very jumbo deflector roll drive motors, increases equipment cost.

Summary of the invention

At the problems referred to above, the invention provides the deflector roll structure of multi-line cutting machine, when it used on big specification lathe, guide rail inertia was little, system control performance good, and need not big capacity guide rail drive motors and drive, reduced equipment cost.

The deflector roll structure of multi-line cutting machine, its technical scheme is such: it comprises conduit, bearing block, the deflector roll periphery, described catheter support is in the described bearing block at two ends, the periphery of described bearing block is set with described deflector roll periphery, it is characterized in that: the periphery of described deflector roll comprises inner steel pipe, middle part carbon fibre composite layer, outside layer of polyurethane, described inner steel pipe socket is loaded on the periphery of described bearing block, the periphery of described inner steel pipe is coated with described middle part carbon fibre composite layer, and the periphery of described middle part carbon fibre composite layer is coated with described outside layer of polyurethane.

Because the periphery of inner steel pipe is coated with middle part carbon fibre composite layer, the mainly distortion of resisting deflector roll by middle part carbon fibre composite layer, carbon fibre composite layer density is little more a lot of than steel, the high good rigidly of intensity, overall structure is light, so when this invention structure was used on big specification lathe, guide rail inertia was little, system control performance good, and need not big capacity guide rail drive motors and drive, reduced equipment cost.
