Description

20 roller mill tension measuring devices

Technical field

The utility model belongs to the sheet metal strip rolling technical field, specifically relates to a kind of 20 roller mill tension measuring devices that strap tension is measured that are used for.

Background technology

At present, the measurement of sheet metal strip rolling tensile force is measured at the slewing rollers place, makes in use to have big shortcoming; Be in particular in: 1, the cornerite of band and slewing rollers changes; Calculate tension force accurately, must accurately measure band, and measurement must be continuous at the actual angle that turns to; Accurately measure difficulty, have the postpone phenomenon; 2, the angle of the direction of power and pressure transducer has reduced the measuring accuracy and the serviceable life of pressure transducer about 45 °.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency of the prior art; A kind of 20 roller mill tension measuring devices are provided; It is simple in structure, reasonable in design and use easy to operate; Improve the measuring accuracy of tension force simultaneously, also improved the serviceable life of pressure transducer, and reduced use cost.

For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of 20 roller mill tension measuring devices; It is characterized in that: comprise slewing rollers, survey and open roller swing arm, a survey roller, pressure transducer, base and fixed arm rotating shaft; Said slewing rollers and pressure transducer are installed on the base; Said pressure transducer is arranged on the rear of slewing rollers, and said survey is opened that the roller swing arm is installed on the base through the fixed arm rotating shaft and can be around fixed arm rotating shaft rotation, and said pressure transducer is positioned at surveys the back lower place of opening the roller swing arm; Said survey is opened that roller is arranged on the slewing rollers rear and is installed in through stationary shaft and rolling bearing and survey to open in the roller swing arm, and said stationary shaft is fixedly mounted on to survey to be opened in the roller swing arm, and said rolling bearing is arranged on stationary shaft and surveys between the roller.

20 above-mentioned roller mill tension measuring devices is characterized in that: said stationary shaft is fixedly mounted on to survey through axial fixing plate to be opened in the roller swing arm.

20 above-mentioned roller mill tension measuring devices is characterized in that: the quantity of said axial fixing plate is two, is symmetrical set before and after two said axial fixing plates.

The utility model compared with prior art has the following advantages:

1, simple in structure, reasonable in design and use easy to operate,

2, the utility model has improved the measuring accuracy of tension force, has improved the serviceable life of pressure transducer, has reduced use cost.

Through accompanying drawing and embodiment, the utility model is done further detailed description below.

Embodiment

As depicted in figs. 1 and 2; The utility model comprises slewing rollers 1, surveys and open roller swing arm 2, a survey roller 3, pressure transducer 4, base 5 and fixed arm rotating shaft 6; Said slewing rollers 1 are installed on the base 5 with pressure transducer 4; Said pressure transducer 4 is arranged on the rear of slewing rollers 1, and said survey is opened that roller swing arm 2 is installed on the base 5 through fixed arm rotating shaft 6 and can be around fixed arm rotating shaft 6 rotations, and said pressure transducer 4 is positioned at surveys the back lower place of opening roller swing arm 2; Said survey is opened that roller 3 is arranged on slewing rollers 1 rear and is installed in to survey through stationary shaft 9 and rolling bearing 8 and opens in the roller swing arm 2, and said stationary shaft 9 is fixedly mounted on to survey to be opened in the roller swing arm 2, and said rolling bearing 8 is arranged on stationary shaft 9 and surveys between the roller 3.

As shown in Figure 2, in the present embodiment, said stationary shaft 9 is fixedly mounted on to survey through axial fixing plate 7 to be opened in the roller swing arm 2.

As shown in Figure 2, in the present embodiment, the quantity of said axial fixing plate 7 is two, and two said axial fixing plate 7 front and back are symmetrical set.

In the utility model, be arranged in after the slewing rollers 1, can guarantee that therefore band 10 forms fixing little cornerite with surveying a roller 3, to improve the measuring accuracy of tension force because a roller 3 is opened in survey; Open roller swing arm 2 fixing formation swing arm fixed sturctures owing to survey a roller 3 through surveying; And surveying a roller swing arm 2 can rotate at fixed arm rotating shaft 6 centers; Therefore make pressure transducer 4 not receive the power of horizontal direction, only receive pressure at right angle, improved the measuring accuracy of tension force and the life-span of pressure transducer; Because the stationary shaft 9 of an installation survey roller 3 is fixed on to survey to open in the roller swing arm 2 through axial fixing plate 7 and does not rotate; Survey and open roller 3 around the rotation of the outer ring of rolling bearing 8; Therefore reduced and surveyed the moment of inertia of opening roller 3, can reduce band 10 and survey the cornerite of opening roller 3, improved measuring accuracy.

During use; Band 10 arrives to survey through slewing rollers 1 opens roller 3; Forming a very little cornerite with survey opening roller 3, the tension force of band 10 being delivered to surveying on the pressure transducer of opening below the roller 34, the true tension force that calculates band 10 according to the force value and the geometry site of pressure transducer 4 outputs.

The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of the utility model technical scheme.
