Description
Technical field
The utility model belongs to field of metallurgy, and especially a kind of electrical control is sent to and rotating novel pipe mill.
Background technology
What send to and the rotary system of pipe mill the earliest adopted all is machinery hydraulic system, and what its position positioning control of sending to relied on is limit switch, and its feed and angle of revolution are controlled by hydraulic system.The frame for movement more complicated of this version, floor space is bigger, and the feed and the control of revolution amount of pricking the pipe machine are inaccurate, and equipment manufacturing cost is higher, and maintenance of equipment is also relatively more difficult.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of electrical control to send to and rotating novel pipe mill, and this pipe mill is simple in structure, send position and feed degree of accuracy height to, and controls by electric controling mode.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of electrical control is sent to and rotating novel pipe mill, by main mill with send rotation control device to and constitute, it is characterized in that: main mill by control circuit with send rotation control device to and be connected, main mill is made of drive motors, gearbox, kinematic link, roll, wherein drive motors is by the belt engages transfer gear box, the output shaft of this gearbox is by the rotating disk of shaft joint connection main mill, and off-centre is installed kinematic link on this rotating disk, and this kinematic link connects roll; Sending rotation control device to constitutes by sending controller to and sending motor, rotation controller and turning motor to, power shaft at the gearbox of main mill connects a reduction box, one pulse coder is installed on the output shaft of this reduction box, a pulse coder all is installed on the power transmission shaft of sending drive axle of motor and turning motor to.
And the pulse coder of being installed on the output shaft of main mill reduction box rotates a circle, and roll carries out a reciprocating motion.
Advantage of the present utility model and beneficial effect are:
1. this bundle pipe machine has been installed the increment type pulse coder that can detect the roll movement position on main mill, can accurately detect any position of roll by this pulse coder, can determine exactly to send to and rotating position thus.
2. main mill can will be sent to rotating moment signal by communication and deliver in their control device, guaranteed to send to and the position of revolution and main mill synchronous.
3. the utility model adopts electric method to substitute traditional machinery hydraulic system fully, adopt motor to send and turn round control to, send the position to by the pulse coder on the main frame main shaft, feed and revolution amount be mounted on send to turning motor on pulse coder control, the moment of action passes to through communication modes by the encoder position signal on the main shaft and sends to and turning motor, has so just improved the degree of accuracy of sending position and feed to effectively.

Fig. 2 is the reciprocal transmission schematic diagram of roll of the present utility model;
Fig. 3 is an electrical control schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
This electrical control is sent to and rotating novel pipe mill, by main mill 4 with send rotation control device 8 to and constitute, main mill by control circuit 14 with send rotation control device to and be connected.Main mill is made of drive motors 10, gearbox 1, kinematic link 6, roll 5, wherein drive motors is by belt 13 engaged transmission gearboxes, the output shaft 2 of this gearbox is by the rotating disk 7 of shaft joint 3 connection main mills, and off-centre is installed kinematic link on this rotating disk, and this kinematic link connects roll.Sending rotation control device to constitutes by sending controller 15 to and sending motor 19, rotation controller 16 and turning motor 17 to, power shaft at the gearbox of main mill connects a reduction box 12, one pulse coder 11 is installed on the output shaft of this reduction box, the pulse coder of being installed on the output shaft of main mill reduction box rotates a circle, and roll carries out a reciprocating motion.One pulse coder 20 is installed sending drive axle of motor to, a pulse coder 18 is installed on the power transmission shaft of turning motor.
In a reciprocating motion of main mill roll, pipe 9 only just can be sent to and be turned round two positions, and promptly in preceding limit B, limit A position, back, other positions are rolling zones.This just needs to detect these two can send to and rotating position, and sends in these two positions and to send and to turn round order to.
Pulse coder is for detecting the increment type pulse coder of roll movement position, and sending the pulse coder that is connected with turning motor to also can be the increment type pulse coder.
Send control device and rotation control device to and adopt separately independently position closed loop control, and accept main mill control by communication modes and send to and rotating position signalling, make the position of itself and main mill synchronous.
Operation principle of the present utility model is:
Non-transmission output shaft (being the output shaft of reduction box) at the main mill gearbox locates to adorn pulse coder, require the speed ratio of encoder should be able to make reciprocating motion of roll, pulse coder rotates a circle, the pulse of pulse coder is delivered to the main mill control system and is handled, can send to and rotating position when counting is handled out main mill work, this position signalling be delivered to by the mode of communication sent to and rotation control device again; Send to rotary system be Position Control, position probing is mounted on their pulse coders on the motor separately, can control and send to and the size of revolution amount.
