Technical Field
The invention relates to the technical field of metal pipe processing machinery, in particular to a novel quick-opening cylinder stable response device of a thermal straightening machine.
Background
The straightening is a crucial process for steel pipe production, and aims to straighten a pipe material so as to meet the requirements of subsequent processing or users. The straightening machine is widely applied to the straightening of steel pipes, and the quick cylinder opening function of the straightening machine is as follows: and (4) leading the pipe head. When the steel pipe is straightened by the straightening machine, the upper straightening roll needs to be quickly pressed down and quickly lifted so as to prevent the end part of the steel pipe from colliding with the upper straightening roll.
At the present stage, a photoelectric correlation switch is widely applied to detect that a steel pipe in the straightener passes through a straightening roller of the straightener, and when the photoelectric switch detects the steel pipe, the photoelectric switch sends a signal to enable a quick-opening cylinder to respond, and the straightening roller is quickly pressed down. However, in the actual production process of the hot straightening machine, fog in the detection area of the photoelectric switch surrounds due to the water cooling of the hot straightening roller, so that the normal detection of the photoelectric emission switch is influenced; the steel pipe can not be accurately detected whether to enter the straightening roll of the straightening machine, so that the quick-opening cylinder can not respond to the situation that the straightening roll is quickly pressed down to perform straightening work.
The invention of application number 201611030653.X discloses an electric control system of a six-roller quick-opening cylinder, which is characterized in that: the electric control system controls the opening and pressing of the quick-opening cylinders of the three upper straightening rollers through the detection element, the electric control system is matched with a hydraulic system to react quickly, the temperature of a steel pipe is required to be 200-400 ℃ in the hot straightening machine, the rollers are cooled by cooling water in order to prevent the roller surface temperature from being too high, and therefore large water mist is caused, and the detection element needs to select a laser switch which can penetrate through the water mist. However, the laser switch detection in the actual production process can not effectively avoid the fog interference and can not accurately detect the steel pipe.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a novel quick-opening cylinder stable response device of a hot straightening machine.
The technical scheme adopted by the invention is as follows:
the utility model provides a novel hot straightener opens jar stable response soon device, the device is located one side of straightener straightening roller bearing frame, its characterized in that: the response device includes: a pressing plate 1; 2, a bakelite plate; a wire brush 3. The steel pipe touches the steel wire brush on the straightening roller through the straightening roller of the straightening machine, an electric appliance loop is connected, and a proximity switch sends a signal to enable the quick-opening cylinder of the thermal straightening machine to stably respond, so that the cooling water mist interference of the straightening roller is avoided. When the steel pipe leaves the straightening roller and cannot contact the steel wire hairbrush, the electric appliance loop is disconnected, the proximity switch does not send a signal, and the quick-opening cylinder of the thermal straightening machine does not respond.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
The utility model provides a novel hot straightener opens jar stable response soon device, the device is located one side of straightener straightening roller bearing frame, its characterized in that: the response device includes: a pressing plate 1; 2, a bakelite plate; a wire brush 3. After the steel pipe passes through the straightening roller of the straightening machine and touches the steel wire brush on the straightening roller, an electric appliance loop is connected, and a proximity switch sends a signal to enable the quick-opening cylinder of the hot straightening machine to stably respond, so that the cooling water mist interference of the straightening roller is avoided. When the steel pipe leaves the straightening roller and cannot contact the steel wire hairbrush, the electric appliance loop is disconnected, the proximity switch does not send a signal, and the quick-opening cylinder of the thermal straightening machine does not respond.
As shown in figure 1, the novel quick-opening cylinder stable response device of the hot straightener comprises a bakelite plate 2, wherein the bakelite plate is positioned on one side of a straightener roll bearing seat of the straightener, and a steel wire brush 3 is arranged between a pressing plate 1 and the bakelite plate 2.
As shown in FIG. 2, the electric schematic diagram of the quick cylinder opening stability response device of the novel hot straightening machine comprises conducting wires 1311dL-, d1321, d1322, d1331, d1332 and d1341 connected to a straightening machine body, and wire brushes-DS 1, -DS2, -DS3, -DS4 and-DS 5 respectively connected to 5 straightening rollers.
Fig. 3 is an electrical schematic diagram of a quick-opening cylinder stable response device of a novel thermal straightener, which comprises an intermediate relay and a PLC.
The working process of the device is as follows:
as shown in figure 2, the steel pipe passes through a straightening machine 1# straightening roller and touches a steel wire brush-DS 1 on the 1# straightening roller, an electric appliance loop is connected, an intermediate relay-KA 99 is normally opened and is attracted, a signal is sent to an input point of an input module of the PLC shown in figure 3, the quick-opening cylinder of the thermal straightening machine is enabled to stably respond through PLC program control, and cooling water mist interference of the straightening roller is avoided. When the steel pipe leaves the straightening roller and cannot contact the steel wire hairbrush, the electric loop is disconnected, the coil of the intermediate relay-KA 99 loses power and does not send a signal, and the quick-opening cylinder of the thermal straightening machine does not respond. The control principle of the quick opening cylinders of the other 2# to 5# straightening rollers is the same as that of the 1# straightening roller.
The leads 1311dL-, d1321, d1322, d1331, d1332 and d1341 in the electrical schematic diagram shown in FIG. 2 are connected to the straightener body. DS1, -DS2, -DS3, -DS4 and-DS 5 represent 5 wire brushes, respectively, which are insulated from the straightener. When the steel pipe contacts the steel wire hairbrush, the corresponding intermediate relay is attracted by utilizing the steel pipe conduction principle. And a normally open contact of the intermediate relay is closed, the PLC receives a corresponding signal, and the quick-opening cylinder of the thermal straightening machine stably responds through PLC program control.
The scheme avoids the water cooling hot straightening roller from causing fog in the detection area of the photoelectric correlation switch to surround and influence the normal detection of the photoelectric correlation switch; the quick opening cylinder can not respond to the problem that the straightening roll is quickly pressed down to carry out straightening work in time because whether the steel pipe enters the straightening roll of the straightening machine or not can not be accurately detected.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
