Abstract

The utility model discloses high-quality roll water-cooled clamping device, it comprises motor (1), the rotating shaft (2) be connected with motor-driven and claw (3), described rotating shaft is communicated with claw inside, described rotating shaft is socketed with the ring-shaped pouring waterpipe (4) be communicated with rotating shaft, described ring-shaped pouring waterpipe is communicated with water source, described claw comprises and first clamping part (5) of roll contacts side surfaces and the second clamping part (6) with roll end contact, and the end face of described first clamping part offers water outlet (7).The beneficial effects of the utility model are that driven by motor rotating shaft and claw rotate, claw clamping roll and then roll also rotate thereupon, while roll rotation, water coolant is injected from ring-shaped pouring waterpipe, the surface of roll is flow to by rotating shaft and water outlet, uniform water-cooled is carried out on breaker roll surface, ensures roller surface Homogeneous cooling.

Description

High-quality roll water-cooled clamping device

Technical field

The utility model relates to clamping device, particularly relates to high-quality roll water-cooled clamping device.

Background technology

Roll is the strength member on Steel Mill's rolling mill, utilize a pair or one group of roll rolls time the pressure that produces to roll stone roller steel.Dynamic And Static Loads when it mainly bears rolling, the impact of wearing and tearing and temperature variation.Roll has different sorting techniques.Be divided into cylindrical and non-cylindrical by body of roll shape, the former is mainly used in sheet material, band, section bar and wire production, and the latter is mainly used in tubing and produces.Roll needs cooling after calcining, quench again, stacked in multi-layers is together often for existing roll, with large-scale fan, surface carried out to it air-cooled, such type of cooling can only be cooled to roll to be exposed to outer part, can not effective temperature-reducing for the roll overlaped, 1 causes roller surface non-uniform temperature, in follow-up quenching, easily occur quality problems.

Utility model content

The technical problems to be solved in the utility model is that existing roll rolipass design mode can only the part exposed surface of breaker roll cool, and cooling performance is bad, roller surface non-uniform temperature, provides a kind of high-quality roll water-cooled clamping device for this reason.

The technical solution of the utility model is: high-quality roll water-cooled clamping device, it comprises motor, the rotating shaft be connected with motor-driven and claw, described rotating shaft is communicated with claw inside, described rotating shaft is socketed with the ring-shaped pouring waterpipe be communicated with rotating shaft, described ring-shaped pouring waterpipe is communicated with water source, described claw comprises and the first clamping part of roll contacts side surfaces and the second clamping part with roll end contact, and the end face of described first clamping part offers water outlet.

The beneficial effects of the utility model are that driven by motor rotating shaft and claw rotate, claw clamping roll and then roll also rotate thereupon, while roll rotation, water coolant is injected from ring-shaped pouring waterpipe, the surface of roll is flow to by rotating shaft and water outlet, uniform water-cooled is carried out on breaker roll surface, ensures roller surface Homogeneous cooling.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1, the utility model comprises motor 1, the rotating shaft 2 be connected with motor-driven and claw 3, described rotating shaft is communicated with claw inside, described rotating shaft is socketed with the ring-shaped pouring waterpipe 4 be communicated with rotating shaft, described ring-shaped pouring waterpipe is communicated with water source, described claw comprises and the first clamping part 5 of roll contacts side surfaces and the second clamping part 6 with roll end contact, and the end face of described first clamping part offers water outlet 7.

Ring-shaped pouring waterpipe in the utility model can be the pipeline that resilient material is made, such as rubber or plastics, by applying the speed that pressure can change hydraulic pressure and then regulate water coolant to flow out from water outlet to ring-shaped pouring waterpipe, ensure that the water coolant of water outlet outflow can flow through the outside surface of roll.The utility model can be use in roll side separately, i.e. one end of a clamping roll, or two use in pairs, clamp the two ends of roll respectively.

Claims

1. high-quality roll water-cooled clamping device, it is characterized in that it comprises motor (1), the rotating shaft (2) be connected with motor-driven and claw (3), described rotating shaft is communicated with claw inside, described rotating shaft is socketed with the ring-shaped pouring waterpipe (4) be communicated with rotating shaft, described ring-shaped pouring waterpipe is communicated with water source, described claw comprises and first clamping part (5) of roll contacts side surfaces and the second clamping part (6) with roll end contact, and the end face of described first clamping part offers water outlet (7).
