Description

Technical Field

[0001] The utility model relates to mechanical equipment, in particular to an automatic cutting machine. Background Art

[0002] In the process of steel pipe processing, long steel pipes need to be cut into equal-length small sections as required. At present, manual cutting is mainly used for processing, and the efficiency is relatively low. Although there are also fully automatic cutting equipment in the form of assembly lines, their prices are expensive and they are only suitable for large-scale processing.

[0003] In addition, in the cutting process, some equipment uses the method of fixing the workpiece and cutting it once. In this method, the workpiece does not need to rotate, and the operation is simple. However, the saw blade is very easy to overheat and jam, and the cut is not flat. There is also equipment that uses the method of rotating the workpiece while cutting. This method has a flat cut, and the saw blade is not easy to overheat and jam. However, it requires additional power to drive the workpiece to rotate, and at the same time, the cooperation between the workpiece and the saw blade during rotation needs to be considered. Therefore, the structure is relatively complex and the cost is high.

[0004] Therefore, how to achieve automatic cutting while minimizing the cost is a technical problem that needs to be solved urgently at present. Summary of the Utility Model

[0021] The beneficial effects of the present utility model are:

[0022] The cutting machine of the present utility model uses a cutting motor to drive the outer drive wheel and the saw blade to rotate, and a rotating wheel is installed on the frame to support the workpiece. The pushing seat and the induction seat are respectively pressed against both ends of the workpiece. The pushing seat drives the movement through the pushing belt to complete automatic feeding, while the induction seat uses an inductor to detect whether the workpiece is pressed tightly. During use, the outer drive wheel is pressed against the workpiece to drive the workpiece to rotate, and the saw blade rotates to cut the workpiece to achieve segmentation. After cutting the workpiece, the blanking wheel applies pressure to one end of the segmented workpiece to quickly discharge the segmented part. At the same time, the inductor detects whether it is discharged. If it is discharged, the pushing seat is used to push the workpiece towards the induction seat for feeding to prepare for the second cutting. This method has a simple structure, accurate cutting dimensions, smooth cut surfaces, can achieve automated operation, and is relatively convenient to use. In addition, the design that the outer drive wheel and the blanking wheel can move relative to the workpiece can ensure that during the cutting process, the outer drive wheel and the blanking wheel always press tightly against the workpiece. Because the cutting machine will rotate relative to the workpiece and the position in the cross-sectional direction of the workpiece will change, the design of the movement of the outer drive wheel and the blanking wheel can flexibly adapt to this situation. At the same time, the present utility model uses a compensation seat to slide on the outer drive wheel to keep the rotating belt taut, which can ensure that the outer drive wheel is driven to rotate during the movement of the outer drive wheel, that is, to keep driving the workpiece to rotate.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0033] See Figures 1 - 6 , the automatic cutting machine in this embodiment is used for cutting and processing cylindrical workpieces 01 that are long and have a circular cross-section, such as steel pipes, plastic pipes, solid shafts, etc.

[0034] The automatic cutting machine includes a frame 100, a cutting machine, an induction seat 410, and a feeding seat 420. A guiding frame 110, an upper frame 120, an adjusting frame 130, a guiding seat 140, a rotating seat 150, a feeding frame 160, and a belt frame 170 are installed on the frame 100. There are two guiding frames 110, and a guiding seat 140 and a rotating seat 150 are respectively installed on each guiding frame 110. The guiding seats 140 and rotating seats 150 on the two guiding frames 110 are respectively attached to both sides of the workpiece 01 to achieve positioning of the workpiece 01.

[0035] A rotating wheel 151 is rotatably installed on the rotating seat 150. The rotating wheel 151 presses against the outer wall of the workpiece 01. When the workpiece 01 rotates, the friction of the rotation of the workpiece 01 is reduced through the rotating wheel 151, and the guiding seat 140 is used for positioning to limit the workpiece 01 inside the guiding seats 140 on both sides, thereby preventing the workpiece 01 from being distorted during rotation.

[0036] A seat sleeve 411 is installed on the induction seat 410. An inductor 260 and a first thrust bearing 510 are installed inside the seat sleeve 411. The inner ring of the first thrust bearing 510 is assembled with the input shaft of the inductor 260, and the outer ring is pressed against the end of the workpiece 01. Thus, the workpiece 01 can apply pressure to the inductor 260 in the axial direction and can rotate relative to the induction seat 410. This can determine whether the end of the workpiece is pressed against the end of the first thrust bearing 510 through the inductor 260 sensing the thrust, and at the same time ensure that the workpiece can rotate circumferentially. In this embodiment, the inductor is selected as a pressure sensor.

[0037] The induction seat 410 is respectively assembled and fixed with one end of an induction optical axis 330 and an induction electric cylinder shaft 221. The other end of the induction optical axis 330 passes through a holding sliding sleeve 131 and is assembled with the telescopic shaft 231 of an adjusting detector 230. The holding sliding sleeve 131 is installed on the adjusting frame 130, the adjusting frame 130 is installed on the frame 100, the adjusting detector 230 is installed on the frame 100, and when the induction optical axis 330 moves, it drives the telescopic shaft 231 to move, so that the adjusting detector 230 detects the displacement of the induction optical axis 330. In this embodiment, the adjusting detector 230 adopts a linear potentiometer, a displacement sensor, etc.

[0038] The induction cylinder shaft 221 is installed inside the induction cylinder 220, and the induction cylinder 220 is installed on the adjusting frame 130. During use, the induction cylinder 220 can be activated to drive the axial expansion and contraction of the induction cylinder shaft 221, thereby driving the synchronous movement of the induction seat 410. The displacement is detected by the adjusting detector 230. This design is mainly to adapt to different cutting lengths. By moving the induction seat 410 carried by the induction cylinder 220, the vertical distance between the end face of the first thrust bearing 510 and the saw blade 810 can be adjusted, and this distance is the length of the material to be cut.

[0039] A guide rail 180 is also installed on the frame. The guide rail 180 is engaged and slidably assembled with the sliding seat 421. The sliding seat 421 is arranged on the pusher seat 420. The pusher seat 420 is fixedly assembled with the pusher belt 710. The pusher belt 710 bypasses the first pusher shaft 340 and the second pusher shaft 171 to form a belt drive mechanism. The first pusher shaft 340 and the second pusher shaft 171 are respectively rotatably installed on the pusher frame 160 and the belt frame 170. A worm gear 531 is installed on the first pusher shaft 340. The worm gear 531 is in meshing transmission with a worm 532. The worm 532 is arranged on the pusher motor shaft 251. The pusher motor shaft 251 is installed inside the pusher motor 250, and the pusher motor 250 is installed on the pusher frame 160. After the pusher motor 250 is started, it drives the pusher belt 710 to run, thereby driving the pusher seat 420 to move to push the workpiece 01 towards the induction seat 410. At the same time, the worm and worm gear transmission has the characteristic of one-way self-locking, which can ensure that the workpiece 01 does not loosen during the cutting process.

[0040] In some embodiments, a second thrust bearing 520 is installed on the pusher seat 420. The inner ring of the second thrust bearing 520 is assembled with the pusher seat 420, and the outer ring is pressed against the end of the workpiece 01. In this way, it can not only push the workpiece towards the induction seat 410, but also not hinder the rotation of the workpiece 01.

[0041] A cantilever frame 121 is arranged on the upper frame 120. The cantilever frame 121 is hinged to the cutting frame 610 of the cutting machine through a rotating shaft 320. The rotating shaft 320 is fixed on the cutting frame 610, and one of the rotating shafts 320 is assembled with the input shaft of the encoder 240. The housing of the encoder 240 is installed on the cantilever frame 121, so as to detect the rotation angle of the rotating shaft 320 by using the encoder.

[0042] The cutting frame 610 is also hinged to the connecting seat 212 through the second connecting shaft 312. The connecting seat 212 is installed on the cutting cylinder shaft 211. The cutting cylinder shaft 211 is inserted into the cutting cylinder 210. The cutting cylinder 210 is hinged to the upper frame 120 through the first connecting shaft 311. After the cutting cylinder 210 is started, it can drive the axial expansion and contraction of the cutting cylinder shaft 211, thereby driving the cutting frame 610 to rotate around the rotating shaft 320. When the saw blade 810 rotates towards the workpiece 01, it is in the cutting state, and the workpiece can be cut at this time; when the saw blade 810 moves away from the workpiece 01, it is in the feeding state, and at this time the saw blade 810 does not contact the workpiece 01 and does not interfere with the movement of the workpiece 01 towards the induction seat 410.

[0043] See Figures 1 - 13 , the cutting machine includes a cutting frame 610, a shield 620, an inner frame 630, and a saw blade 810. The shield 620 and the inner frame 630 are both fixedly installed on the cutting frame 610. The saw blade 810 is sleeved and fixed on the driving shaft 360. The driving shaft 360 is rotatably assembled with the inner frame 630 in a circumferential manner. The driving shaft 360 is connected to the output shaft of the cutting motor 270 through a driving belt 750 to form a belt transmission mechanism. The cutting motor 270 is installed on the inner frame 630. In some embodiments, an inner frame cylinder 631 is provided on the inner frame 630, and the driving shaft 360 passes through the inner frame cylinder 631 and is rotatably assembled with it in a circumferential manner.

[0044] The rotating belt 740 bypasses the driving shaft 360, the outer driving wheel shaft 351, and the compensation shaft 352 to form a belt transmission mechanism. An outer driving wheel 730 is sleeved and fixed on the outer driving wheel shaft 351. The outer driving wheel shaft 351 is rotatably installed on the outer driving wheel frame 731. A rotating spline shaft 732 is installed on the outer driving wheel frame 731. After the rotating spline shaft 732 is sleeved with the outer driving spring 733, it passes through the inner frame 630 and is not rotatable relative to the inner frame 630 in a circumferential manner (spline and spline groove fit). The outer driving spring 733 applies an elastic force to the outer driving wheel frame 731 to push it away from the inner frame 630 and towards the workpiece 01, so that the outer driving wheel 730 remains pressed against the outer wall of the workpiece 01 during use.

[0045] The compensation shaft 352 is rotatably mounted on the compensation seat 640. The compensation seat 640 is engaged and slidably assembled with the compensation slide rail 650. The compensation slide rail 650 is fixedly mounted on the inner frame 630. One end of the elastic drawstring 820 is fixedly assembled with the compensation seat 640. The other end of the elastic drawstring 820 is fixedly assembled with the inner frame 630 after passing around the guide pulley 830. The elastic drawstring 820 has elasticity. The guide pulley 830 is rotatably mounted on the inner frame 630 through the guide pulley shaft 831. The guide pulley 830 is used to change the direction of the elastic drawstring 820. In the initial state, the thrust applied by the external drive spring 733 to the external drive wheel frame 731 is relatively large. Therefore, the compensation shaft 352 and the compensation seat 640 are pulled by the rotating belt 740 to move towards the rotating spline shaft 732 to the maximum displacement point. The elastic drawstring 820 is in a state of being stretched and storing elastic force. Once the external drive wheel frame 731 moves towards the inner frame 630, the elastic drawstring 820 pulls the compensation seat 640 to move away from the rotating spline shaft 732 to maintain the tension of the rotating belt 740, that is, to ensure that the rotating belt 740 is in a normal operating state.

[0046] See Figure 8 In some embodiments, a shaft plate 621 is fixed on the outer cover 620. The blanking spline shaft 722 passes through the shaft plate 621 and is non-rotatably assembled therewith. The bottom of the blanking spline shaft 722 is assembled with the blanking wheel frame 721. A blanking wheel 720 is rotatably mounted on the blanking wheel frame 721. A blanking spring 723 is sleeved on the portion of the blanking spline shaft 722 between the shaft plate 621 and the blanking wheel frame 721. The blanking spring 723 applies a thrust to the blanking wheel frame 721 to move it away from the shaft plate 621.

[0047] The operation process of this embodiment is generally as follows:

[0048] S1. Load the workpiece 01 and place the workpiece 01 between the two side guide seats 140 and the rotating wheel 151, as well as between the first thrust bearing 510 and the second thrust shaft gear 520 at both ends.

[0049] S2. Start the induction cylinder 220 to drive the induction seat 410 to move to adjust the length of the cut section.

[0050] S3. Start the pusher motor 250. The pusher motor 250 drives the pusher belt 710 to run to drive the pusher seat 420 to move until the sensor 260 detects that the workpiece is pressed against the first thrust bearing. Specifically, if the sensor 260 is a pressure sensor, it detects the pressure transmitted from the end of the first thrust bearing 510. When the preset pressure value is reached, it can be determined that the workpiece is pressed against the first thrust bearing 510. For example, when the pressure reaches more than 5N.

[0051] S4. Start the cutting electric cylinder 210 and the cutting motor 270. The cutting motor 270 drives the outer drive wheel 730 and the saw blade 810 to rotate. The cutting electric cylinder 210 drives the outer drive wheel 730 and the saw blade 810 to rotate towards the workpiece. The outer drive wheel 730 and the blanking wheel 720 first press against the workpiece 01, and then squeeze the corresponding outer drive spring 733 and blanking spring 722. The outer drive wheel 730 drives the workpiece to rotate, and then the saw blade 810 gradually contacts the workpiece and starts to cut the workpiece.

[0052] S5. The encoder detects the rotation angle of the cutting machine. Until the preset angle is reached, the cutting electric cylinder 210 stops driving the cutting machine to rotate towards the workpiece. At this time, it is judged that the workpiece is cut off. Once the workpiece is cut off, it will fall under the push of the blanking wheel 720. At this time, the sensor 260 can detect it. Therefore, the cutting machine can be stopped from rotating towards the workpiece after the sensor 260 detects the pressure change. And at this time, the cutting electric cylinder 210 drives the cutting machine to rotate away from the workpiece and reset. The encoder detects the maximum rotation of the cutting machine to prevent the cutting machine from rotating excessively and causing collisions. And at this time, the cutting electric cylinder 210 drives the cutting machine to rotate away from the workpiece and reset.

[0053] S6. After cutting and discharging the material, the pusher motor 250 is started to push the workpiece towards the induction seat until the sensor detects the pressing again, and then cutting is performed again until the pusher seat 420 moves to the maximum displacement point towards the induction seat 410. After the pusher seat 420 moves backward and resets, reloading starts.

[0054] In some embodiments, the driving shaft 360 is not directly assembled and driven with the rotating belt 740. Instead, after the driving shaft 360 is decelerated by a speed reducer, the output shaft of the speed reducer is then assembled and driven with the rotating belt 740. This design can reduce the rotation speed of the outer drive wheel to avoid the excessive rotation speed of the workpiece affecting the cutting.
