Abstract
The utility model discloses a force measuring mechanism of a low relaxation prestressed steel strand, comprising a roller(1), a swinging bracket(3), a pressure sensor(5) and a pedestal(8). The pedestal(8) is equipped with a limiting bolt(6) via a nut(7), and a lower bearing via a lower bearing base(4), one part of the bottom of the swinging bracket(3) is arranged on the limiting bolt(6), and the other part is arranged on the lower bearing(4); the roller(1) is arranged on the top of the swinging bracket(3) via an upper bearing base(2) and an upper bearing, the pressure sensor(5) is arranged on the pedestal(8) and is located right below the swinging bracket(3). In the utility model, the positive pressure of the roller(1) given by a tension is measured by the pressure sensor(5), displayed as a digital form and fed back to a control system, realizing a closed-loop control, and providing reliable quality guarantee for the production of the low relaxation prestressed steel strand.
Description
Technical field
The utility model relates to force measuring machine, is specifically related to a kind of force measuring machine of low relaxed prestress steel strand.
Background technology
The fast development of wire fabrication industry, the annual production of low relaxed prestress steel strand is doubled and redoubled, and the annual production of low relaxed prestress steel strand has reached 5,000,000 tons.Low relaxed prestress steel strand equipment dependence on import always before 5 years, in recent years, we have realized production domesticization by digesting and assimilating with this equipment, gordian technique has also had than much progress.The relax of low relaxed prestress steel strand, stretching property etc. have much relations with the tension force size, and therefore, the on-line tension of low relaxed prestress steel strand mensuration and signal feedback are very important.
Summary of the invention
The purpose of this utility model is: the force measuring machine that a kind of low relaxed prestress steel strand is provided, the tension force of low relaxed prestress steel strand shows and feeds back to digital form by this force measuring machine realizes closed-loop control in the control system, provide reliable quality assurance to the production of low relaxed prestress steel strand.
Technical solution of the present utility model is: this force measuring machine comprises roller, swinging mounting, pressure transducer and base, through nut stop screw is installed on the base, through step lower bearing is installed on the base, the part of the bottom of swinging mounting is installed on the stop screw, another part of the bottom of swinging mounting is installed on the lower bearing, roller is installed through top chock, head bearing in top at swinging mounting, setting pressure sensor on the base, pressure transducer be positioned at swinging mounting under.
During installation, swinging mounting and roller form an integral body, can swing up and down around step; During work, roller is under the effect of very big steel strand wires tension force F, very little power of pressure transducer under swinging mounting is given it, the data of reading from pressure transducer are by calculating the size of tension force, digitized parameter is applied among the PLC of control system, adjusts and control tension force.
The utility model measures for the normal pressure of roller by tension force by pressure transducer, show and feed back in the control system with digital form, power that will be bigger changes power less, that be convenient to measure into cleverly by force measuring machine, output by electric signal, make system realize the closed loop Tension Control, guarantee for low relaxed prestress steel strand production provides reliable quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 roller, 2 top chocks, 3 swinging mountings, 4 steps, 5 pressure transducers, 6 stop screws, 7 nuts, 8 bases.
Embodiment
As shown in Figure 1, this force measuring machine comprises roller 1, swinging mounting 3, pressure transducer 5 and base 8, through nut 7 stop screw 6 is installed on the base 8, through step 4 lower bearing is installed on the base 8, the part of the bottom of swinging mounting 3 is installed on the stop screw 6, another part of the bottom of swinging mounting 3 is installed on the lower bearing 4, roller 1 is installed through top chock 2, head bearing in top at swinging mounting 3, setting pressure sensor 5 on the base 8, pressure transducer 5 be positioned at swinging mounting 3 under.
During installation, swinging mounting 3 forms an integral body with roller 1, can swing up and down around step 4; During work, roller 1 is under the effect of very big steel strand wires tension force F, 5 one very little power of pressure transducer under swinging mounting 3 is given it, the data of reading from pressure transducer 5 are by calculating the size of tension force, digitized parameter is applied among the PLC of control system, adjusts and control tension force.
