Abstract
The utility model discloses a roller pressure warning device for a rolling machine. The roller pressure warning device for the rolling machine comprises a plurality of pressure sensors which are arranged on rounded surface edges of a roller and a controller; a connecting line of the two corresponding pressure sensors passes a center of the rounded surface; the controller is connected with a motor of a winding machine; the pressure sensors is in wired signal connection with the controller when passes a contact position of the roller and strip belt. The roller pressure warning device for the rolling machine achieves online monitoring in real time and effectively protecting key components such as the roller.
Description
Technical field
The utility model belongs to rolling mill technical field, is specifically related to a kind of nip pressure prior-warning device of rolling mill.
Background technology
In rolling machinery; when various steel heats, cold-rolling mill are changed product specification; need to adjust the draught pressure of roll, or increase screwdown gear between roll and frame, but due to the difference of concrete material; detect after the indexs such as raw material hardness; in the operation of rolling, can not realize online detection in real time, often there will be unexpected situation; when the hardness number of material has exceeded after preset value, cause the damage of the important spare parts such as roll.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of nip pressure prior-warning device of rolling mill is provided, and this device can be realized on line real time control, and the degree of accuracy is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of nip pressure prior-warning device of rolling mill, comprise the pressure sensor at multiple disc edges that are laid in roll, and the connecting line of two corresponding pressure sensors is through the center of circle of disc, also comprise controller, this controller is connected with the motor of hoist engine; , be connected with controller wire signal when described pressure sensor contacts with the strip through roll the position.
Further, this roll is working roll.
Further, this pressure sensor is resistance capacitance element.
Further, the angle of the line of this adjacent pressure sensor and each self-corresponding pressure sensor is 30 degree.
The nip pressure prior-warning device of a kind of rolling mill of the utility model, realize the hardness that real time and on line monitoring enters the raw material of roll, and be connected with roll control motor, in the time that raw material hardness number exceeds preset value, roll quits work, and has avoided the damage of the vitals such as roll.
Accompanying drawing explanation
Fig. 1 is the nip pressure prior-warning device schematic diagram of a kind of rolling mill of the utility model;
Wherein: 1, roll; 2, pressure sensor; 3, controller; 4, motor.
The specific embodiment
As shown in Figure 1, a nip pressure prior-warning device for rolling mill, comprises the pressure sensor 2 at multiple disc edges that are laid in roll 1, and the connecting line of two corresponding pressure sensors 2 is through the center of circle of disc, also comprise controller 3, controller 3 is connected with the motor 4 of hoist engine; , be connected with controller 3 wire signals when pressure sensor 2 contacts with the strip through rolls 1 the position.This roll 1 is working roll, and this pressure sensor 2 is resistance capacitance element.Adjacent pressure sensor 2 is 30 degree with the angle of the line of each self-corresponding pressure sensor 2.Controller 2 is preset with a force value, and in the time that raw material enters roll 1, if the hardness of raw material exceeds default force value, the pressure sensor 2 that is attached to roll 1 side deforms, and signal is passed to controller 3.
