Description
Technical field
The utility model relates to a kind of accurate titanium welding pipe production line of titanium pipe, particularly a kind of speed control system of titanium welding pipe production line.
Background technology
Traditional titanium welding pipe production line, when handling shaping machine set, sizing unit and pulling out speed control between the unit, employing be that the drive motor rotating speed and the actual speed of each drive motor relatively are set, guarantee that with this whole production line speed is controlled substantially.Because drive motor when driving roll, the contact point of each roll and titanium pipe is not in same diameter of axle position, have under roll, the side that has at roll, so even motor speed all is identical, but the linear velocity of titanium pipe is the but difference to some extent of actual speed of unit.And titanium pipe matter is soft, if the front and back gantry speed is inconsistent, will form impression at the titanium tube-surface, influence the quality of titanium pipe and attractive in appearance, and, when heat-treating, heating-up temperature is than higher, if this moment reducing mill stand linear velocity ratio to pull out the frame linear velocity fast, the titanium pipe will be in heating zone flexural deformation so, if it is slow that the sizing velocity ratio is pulled out speed, the titanium pipe will be elongated drawing-down so, and the titanium pipe under two kinds of situations all is underproof.At this moment, operating personnel must pass through experience, and the speed fine setting is carried out in electric current variation etc., has brought inconvenience to production, has reduced production efficiency.
Summary of the invention
For solving the problems referred to above that prior art exists, the utility model will design a kind of titanium welding pipe line speed control system that can control shaping machine set, sizing unit automatically and pull out speed between the unit.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of titanium welding pipe line speed control system, comprise Programmable Logic Controller, counting module, shaping machine set DC speed regulator, sizing unit DC speed regulator, pull out unit DC speed regulator and operation screen, described Programmable Logic Controller respectively by Profibus DP bus network and shaping machine set DC speed regulator, sizing unit DC speed regulator, pull out the unit DC speed regulator and shield with operation and be connected; Described counting module respectively with thermal treatment before scrambler be connected with scrambler after the thermal treatment, scrambler is between sizing unit and heat treating equipment before the described thermal treatment, scrambler is in heat treating equipment and pull out between the unit after the described thermal treatment, described Programmable Logic Controller also is connected with counting module by the back bus, and described counting module is in Programmable Logic Controller is installed in switch board.
