Description

The numerical control hydraulic pipe cutting machine tool

Affiliated technical field

The utility model relates to a kind of hydraulic pressure controlled machine and is fit to the various tubing uses of cutting.

Background technology

At present, in various mechanical processing process, manual mechanical device is mostly adopted in cutting to tubing, manually cutting is taken turns the cutting of finishing tubing to move by hand to cut, automatic cutting device is often to utilize toothed metal saw blade or thin grinding wheel, cut with driven by motor, its weak point is that noise is big, and surrounding environment is caused very big harm, and the cutting powder flies upward everywhere, have a strong impact on people's physical and mental health, the tubing otch is irregular, and length is difficult to control, and precision is low, can not automated production, make troubles to industrial mass production.

Goal of the invention

For solving above deficiency to incising pipes processing, the purpose of this utility model provides a kind of numerical control hydraulic pipe cutting machine tool, utilizes hydraulic means and Programmable Logic Controller, to realize the automated production to tubing high accuracy, noiselessness cutting.

Structural design of the present utility model is achieved in that the structure of pipe cutting machine tool forms (as shown in the figure) by cutting mechanism two parts of following casing and tubing feed mechanism and tubing, in the following casing Programmable Logic Controller and work drive motor are housed, on casing, tie mutually and should be fixed with the pipe cutting machine structure with motor, the cutting mechanism center is hollow splined shaft, the splined shaft two ends is equipped with ball bearing, belt pulley is equipped with in one end bearing outside, connect with motor output shaft with belt, the splined shaft outside is with Hollow hydraulic cylinder, annular piston is housed in the Hollow hydraulic cylinder, the piston fixed outside has yoke plate, yoke plate is a pole, the center is a fixed rotating shaft, the one end connects with rotating shaft with annular piston, the other end connects with cutoff knife rack, be fixed with cutting knife on the cutoff knife rack, in the Hollow hydraulic cylinder side location-plate is housed, sensor is housed on the location-plate, corresponding at casing opposite side and hollow splined shaft is the tubing feed mechanism, the inside is independent gripping mechanism, the outside is for sending the material gripping mechanism, the feeding gripping mechanism connects with feeding oil cylinder, be two semicircular arc circles in the middle of gripping mechanism and the feeding gripping mechanism separately and roll relative fixed, the side is circle wheel jackscrew, the Hollow hydraulic cylinder of lathe and feeding cylinder all connect with pumping plant, and all device is an integral body after connecting.

The advantage of the utility model: this pipe cutting machine tool reasonable in design, adopt hydraulic feed and cutting, noiselessness, no dust, cutting accuracy height, by control able to programme carry out tubing cutting automatically, are a kind of comparatively desirable pipe cutting machines, can promote the use of.

Description of drawings

Fig. 1 is a numerical control hydraulic pipe cutting machine tool structure principle chart.

The specific embodiment

Its structure is by shown in the accompanying drawing:

1 is pumping plant, supplies with whole device hydraulic pressure, 2,3,4 is feed arrangement, wherein 2 are the feeding cylinder, and 3 are the feeding gripping mechanism, and 4 is independent gripping mechanism, remainder is the tubing cutter sweep, and wherein 5 is the support of bearing, and 6 is yoke plate, 7 is Hollow hydraulic cylinder, and 8 is belt pulley, and 9 is location-plate, 10 sensors, 11 motor, 12 hollow splined shafts, 13 cutter hubs, 14 cutting knifes, 15 Programmable Logic Controllers, 16 annular pistons, 17 is casing, operation principle, motor rotates, and drives hollow splined shaft rotation by belt, be with Hollow hydraulic cylinder in the splined shaft outside, drive annular piston and stretch out, promote the cutter hub cutting knife to by the center feeding of Pipe Cutting material, finish cutting by the yoke plate support owing to the outer of annular piston moves, sensor by Programmable Logic Controller provides signal, directly controls hydraulic means and cuts automatically by specification requirement.
