Description
Technical field
The utility model relates to the auxiliary device of color steel production line, specifically refers to that color steel cuts off the good band-saw machine of accuracy.
Background technology
Band-saw machine is the auxiliary device of color steel production line, for the cut-out of color steel, when color steel from compounding machine out after, just through band-saw machine, usually cut according to the Cutting Length of program setting.But the physical length of the color steel often cut out and the different of program setting, error is within every meter ± 5mm, and each length is also all different.Long or short, uneven, the qualification rate of the color steel of working it out so does not just reach.Normally do length a bit now, by later stage artificial secondary operations, ensure that the color steel dispatched from the factory is all equally long like this.Cause very large waste to manufacturer, one is later-stage secondary processing cost of labor, and the unnecessary leftover pieces of the length of the second waste, the cost of the product improved greatly, loses the market competitiveness, and production efficiency is also very low.
The course of work that existing band-saw machine cuts off color steel is as follows: see Fig. 1,2,3 and 4, cylinder 1 drives cutting rack 2 to vertically move in orbit, when color steel from color steel wire composite host out time, because color steel wire is all continuous seepage, so will, color steel transversely cutting, must be cutting on line.So-called cutting on line is exactly that ejecting plate is while cutting.So cutting on line must ensure that the speed that cutting rack 2 and color steel production line are produced is consistent, transverse cuts dolly 3 drives saw blade 4 to do transverse movement simultaneously, and color steel is cut off.After cut-out, cylinder 1 drives cutting rack 2 back to reset fast, waits for instruction next time.
That cylinder 1 drives cutting rack 2 to move reciprocatingly on the rail 5 in this process, due to 1, the air pressure of control cylinder 1 is unstable, even if added pneumatic control valve be also difficult to ensure that the reciprocating motion of cylinder 1 is at the uniform velocity, 2, frictional force is also very large on the rail 5 for the running roller of cutting rack 2, so be difficult to ensure that the speed that cutting rack 2 and color steel production line are produced is consistent, thus result in the color steel problem that cutting accuracy is inaccurate in length cutting.
Utility model content
For the problems referred to above that prior art exists, the purpose of this utility model is to provide the good band-saw machine of a kind of color steel shearing length accuracy.
For achieving the above object, the utility model adopts following technical scheme: color steel cuts off the good band-saw machine of accuracy, comprises cutting rack, line slideway, ball-screw and servomotor; The bottom of described cutting rack is installed with slide block, and the bottom of slide block has groove, and described line slideway passes from this groove, and line slideway slidably coordinates with groove; The medial surface of described groove has the protuberance arranged in opposite directions; Described line slideway two lateral surfaces along its length has depressed part respectively; Depressed part on protuberance on described groove medial surface and line slideway two lateral surfaces cooperatively interacts; Described ball-screw is parallel with line slideway, ball-screw is arranged with the screw with its threaded engagement, and described screw is fixedly connected with the bottom of cutting rack; The output shaft of described servomotor is connected with ball-screw by shaft coupling.
As optimization, also comprise the controller be connected with servomotor communication.Relative to prior art, the utility model tool has the following advantages:
The utility model provides band-saw machine to drive the rotation of ball-screw by servomotor, and then the movement of cutting rack is realized by the movement of the screw with ball-screw threaded engagement on ball-screw, the Distance geometry speed that cutting rack vertically moves well can be controlled by servomotor, thus realize speed that cutting rack vertically moves and the speed that color steel line is produced is consistent, ensure that the cutting accuracy of color steel.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 5-Fig. 8, color steel cuts off the good band-saw machine of accuracy, comprises cutting rack 2, line slideway 9, ball-screw 8 and servomotor 7.
The bottom of cutting rack 2 is installed with slide block 10, and this slide block 10 is located on line slideway 9, and can linearly move by guide rail 9 length direction, and the bottom of slide block 10 has groove particularly, and line slideway 9 passes from this groove, and line slideway 9 slidably coordinates with groove.
In order to anti-limited slip block 10 rocks in sliding process, even depart from line slideway 9, following design done to the cooperation of slide block and line slideway:
The medial surface of groove has the protuberance arranged in opposite directions; Line slideway 9 two lateral surfaces along its length has depressed part respectively; Depressed part on protuberance on groove medial surface and line slideway 9 two lateral surfaces cooperatively interacts, and namely protuberance is just positioned at depressed part, thus carries out spacing to slide block, and anti-limited slip block 10 rocks in sliding process.
Ball-screw 8 is parallel with line slideway 9, and ball-screw 8 is arranged with the screw 5 with its threaded engagement, screw 5 is fixedly connected with the bottom of cutting rack 2; The output shaft of servomotor 7 is connected with ball-screw 8 by shaft coupling 6.
As optimization, this band-saw machine also comprises the controller be connected with servomotor 7 communication, and controller can be PLC, when specifically implementing, can programme as required to PLC, realize the control to servomotor 7.
The operation principle of the utility model band-saw machine is as follows:
Start servomotor 7, the output shaft of servomotor 7 is connected with ball-screw 8 by shaft coupling 6, power is reached ball-screw 8, and drive ball-screw 8 to rotate, ball-screw 8 rotarily drives screw 5 and moves thereon; The rotation of ball-screw, the power that servomotor 7 is passed over by shaft coupling 6, controlled by servomotor 7 completely, so just well can control the Distance geometry speed that cutting rack 2 vertically moves, can also by the communication of PLC, thus ensure that the speed that cutting rack 2 vertically moves and the speed that color steel line is produced are consistent completely, realize zero error.So absolute guarantee's cutting accuracy of color steel.By controlling the rotation direction of servomotor 7, realize the control to screw 5 moving direction on ball-screw 8.
Be connected and fixed bottom screw 5 and cutting rack 2, thus screw 5 drives cutting rack 2 to move reciprocatingly on line slideway 9.Slide block 10 is fixed on the bottom of cutting rack 2, and slide block 10 directly slides on line slideway 9, less than the running roller coefficient of sliding friction had like this, walks more steady.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
