Description
Technical field:
The present invention relates to veneer reeling machine technical field, be specifically related to a kind of high precision numerical control set round machine.
Background technology:
The technique utilizing roll forming technology sheet material to be twisted into cylinder is widely used in fields such as automobile exhaust pipeline, the manufacture of pump industry, ventilating engineering, plate making and even military project manufactures.But its circularity precision is lower after welding for obtained cylinder, have impact on the expansion of its range of application and making full use of of material.For overcoming above-mentioned defect, need to carry out set round to rolling the workpiece after barrel soldering.Existing set round technique major part uses conventional veneer reeling machine operation, and labour intensity is large, and operating accuracy is low.Also all there is above-mentioned defect in the so-called automatic circle calibration machine of minority.
Existing set round (school circle) device and the main working parts of the equipment top roll moving up and down that to be the lower roll be parallel to each other that two centre-to-centre spacing is certain parallel with lower roll between two lower rolls with.Lower roll provides main driving by motor through reductor, drives workpiece to rotate.Top roll is driven by transmission device or oil cylinder and moves up and down.The set round of various different size workpiece is adapted to by the distance adjusting top roll and two lower roll center lines.But traditional bolt and nut transmission is worked by sliding friction, use middle because friction cause gap increase and reduce precision.Hydraulic cylinder then affects set round precision because the compressibility of its working media (hydraulic oil) cannot keep the stable of work clearance between roll when set round.
Summary of the invention:
The object of this invention is to provide a kind of high precision numerical control set round machine, it substitutes traditional bolt and nut transmission or hydraulic cylinder, realizes the accurate adjustment of the spacing of top roll and two lower roll center lines, in order to realize high accuracy set round.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises top roll 1, lower roll 2, lower roll transmission mechanism 3, lower roller driving mechanism 4, PLC 5, and it also comprises lead-screw drive mechanism 6 and displacement transducer 7; Top roll 1 both sides are connected with lead-screw drive mechanism 6 respectively, and the side of lower roll 2 is provided with displacement transducer 7, and displacement transducer 7 is connected with PLC 5.
Set round process of the present invention adopts following journey: set round process is divided into N number of passage by it, first each passage lower roll 2 drives workpiece rotating each 1-2 week, described top roll 1 and the spacing of two lower roll 2 center lines reduce gradually by 1-N passage, then increase gradually by N-1 passage, residual stress in workpiece is through ascending, descending again process, while top roll 1 successively presses down, change the unidirectional mode operating as positive and negative alternate continuously of lower roll 2, make stressed more balanced in all directions of workpiece, effectively improve set round precision.
Operator can be calculated by the information such as diameter, thickness, properties of materials of input workpiece
Go out passage that top roll presses down, cycle and speed, top roll presses down and the displacement risen, and generates a set of work order program being suitable for associated workpiece, realizes the Digital Control of set round process.
The present invention is by the operating position of high accuracy displacement sensor identification top roll, and instantaneous feedback is to PLC.PLC compares the action such as rotating forward, reversion, stopping according to the lifting of the programme-control top roll preset, rising or falling speed and lower roll of top roll displacement and setting value in real time, use proximity switch detects the limiting condition of tilting device and top roll, and PLC is according to the introduction, elucidation of the theme of these status informations in conjunction with the action of pre-conditioned control set round.
The present invention adopts above-mentioned high-precision transmission device, displacement state sensor and PLC software programming to control to coordinate, and is aided with sensitive executive component and reaches measurement precisely, feed back sensitive, control accurate object.The model machine manufactured experimently according to this most colleges and universities circle precision reaches 0.1 millimeter.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
Referring to Fig. 1, this detailed description of the invention is by the following technical solutions: it comprises top roll 1, lower roll 2, lower roll transmission mechanism 3, lower roller driving mechanism 4, PLC 5, and it also comprises lead-screw drive mechanism 6 and displacement transducer 7; Top roll 1 both sides are connected with lead-screw drive mechanism 6 respectively, and the side of lower roll 2 is provided with displacement transducer 7, and displacement transducer 7 is connected with PLC 5.
This detailed description of the invention adopts following flow process: set round process is divided into N number of passage by it, first each passage lower roll 2 drives workpiece rotating each 1-2 week, described top roll 1 and the spacing of two lower roll 2 center lines reduce gradually by 1-N passage, then increase gradually by N-1, residual stress in workpiece is through ascending, descending again process, while top roll 1 successively presses down, change the unidirectional mode operating as positive and negative alternate continuously of lower roll 2, make stressed more balanced in all directions of workpiece, effectively improve set round precision.
This detailed description of the invention operator can calculate passage that top roll presses down, cycle by the information such as diameter, thickness, properties of materials of input workpiece, top roll presses down and the displacement risen, generate a set of work order program being suitable for associated workpiece, realize the Digital Control of school circle process.
This detailed description of the invention is by the operating position of high accuracy displacement sensor identification top roll, and instantaneous feedback is to PLC.PLC compares the action such as rotating forward, reversion, stopping according to the lifting of the programme-control top roll preset, rising or falling speed and lower roll of top roll displacement and setting value in real time, use proximity switch detects the limiting condition of tilting device and top roll, and PLC is according to the introduction, elucidation of the theme of these status informations in conjunction with the action of pre-conditioned control set round.
This detailed description of the invention adopts above-mentioned high-precision transmission device, displacement state sensor controls to coordinate with PLC software programming, is aided with sensitive executive component and reaches measurement precisely, feed back sensitive, control accurate object.The highest tender round precision of the model machine manufactured experimently according to this reaches 0.1 millimeter.
