Abstract

The utility model relates to a split press roller for a roll squeezer. A plurality of roll surface blocks are installed on the shaft surface of the roller shaft, the roller shaft is a polygon-shaped cylindrical body, the roll surface blocks are fan-shaped blocks, and the split press roller is assembled and formed by a double wedge surface type clamping device between the roller shaft and the roll surface fan-shaped blocks. The utility model has the advantages that difficult assurance of the integral type forging quality, high manufacturing cost, difficult disassembly and repair and others problems can be solved, the problem that the sleeve of the roller is split at times caused by the difficult control of the fit tolerance between the sleeve of the roller and the roller shaft of a roller sleeve type press roller can be solved, over 20% of the manufacturing cost can be saved, and over 50% of the repairing construction period can be shortened.

Description

Roll squeezer piecemeal pin-connected panel pressure roller

The utility model belongs to the device in the material disintegrating apparatus, particularly a kind of roll squeezer piecemeal pin-connected panel pressure roller.

Roll squeezer is a kind of high efficiency disintegrating apparatus, it is to utilize the pressure roller that is arranged in parallel on two same horizontal planes, under the driving of its transmission device, rotate in opposite directions, and one of them pressure roller can carry out floating of relative and another fixing pressure roller under the effect of hydraulic loading system.When obtaining extruding (intergranular extruding in the so-called material bed) during by the formed roll gap of two pressure rollers, pulverizes material.And existing roll squeezer exists squeezing effect poor, and operational reliability is poor, serious wear, problem such as easy-maintaining and cost of use height not.Existing pressure roller is to adopt monoblock type or roll sleeve type, exist forging quality to be difficult to guarantee for the monoblock type pressure roller, manufacturing cost is high and dismantle problems such as keeping in repair difficulty, and exists the fit tolerance of roller shell and roll shaft to be difficult to control for the roll sleeve type pressure roller, causes the problem of roller shell cracking often.

The purpose of this utility model provides a kind of roll squeezer piecemeal pin-connected panel pressure roller, overcomes above-mentioned shortcoming and defect.

The purpose of this utility model is achieved in that

A kind of roll squeezer piecemeal pin-connected panel pressure roller is characterized in that: on the axial plane of roll shaft, a plurality of roll surface pieces are housed.

The cross section of roll shaft is the cylinder of many prismatics, and the roll surface piece of Pei Heing is a secter pat with it.

Each roll surface secter pat of junction handlebar and roll shaft in the both sides of roll shaft and roll surface secter pat fit together the shape of a saddle folding wedge face formula clamping device that forms piecemeal pin-connected panel pressure roller.

The cross section of roll shaft is the cylinder of many prismatics, and seamed edge is generally 6 to 10.

The utility model has the advantages that:

Promethean like this design both can solve the monoblock type forging quality and be difficult to problems such as assurance, manufacturing cost height and dismounting maintenance difficulty, can solve the fit tolerance that the roll sleeve type pressure roller exists roller shell and roll shaft again and be difficult to control, often cause the problem of roller shell cracking, manufacturing cost can be saved more than 20%, the maintenance duration can be shortened more than 50%.

Below in conjunction with description of drawings embodiment:
