Description

Technical Field

[0001] This application relates to the field of pipe processing equipment technology, and in particular to a chipless cutting machine. Background Technology

[0002] Currently, in the production of plastic pipes, pipe cutting uses two methods: saw blade cutting and chipless cutting. The feed method uses hydraulic or frequency conversion mechanical feed. When changing the specifications of the pipe being cut, it is necessary to stop the machine and adjust the feed limit. However, the center height of pipes with particularly large diameters is relatively high, making adjustment extremely inconvenient. During hydraulic feed, the pressure of the hydraulic cylinder increases as the cutting is nearing its end. Occasionally, excessive pressure in the hydraulic cylinder can lead to leakage, resulting in unstable feed and affecting the cutting effect of the pipe, causing white edges to appear on the cut. Summary of the Invention

[0006] A saw blade cutting device is mounted on the mounting plate. The saw blade cutting device includes a first electric cylinder, a cutting saw blade, and a cutting motor. The first electric cylinder is driven by the cutting saw blade to drive the cutting saw blade to advance and retract into the through hole.

[0020] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0021] This application provides a chipless cutting machine, such as... Figure 1 As shown, the chipless cutting machine includes: a mounting plate 10, a saw blade cutting device 20 and a chipless cutting device 30 arranged opposite to each other, and a control system (not shown in the figure) for selectively controlling the forward and backward movement of either the saw blade cutting device 20 or the chipless cutting device 30.

[0022] Mounting plate 10 is mounted on a frame for conveying pipes. A through hole 1 for the pipes to pass through is formed at the center of mounting plate 10. A saw blade cutting device 20 and a chipless cutting device 30 are mounted around the through hole 1 and opposite each other on the same side of mounting plate 10. Mounting plate 10 is configured to rotate about the centerline of the through hole 1, allowing the saw blade cutting device 20 or the chipless cutting device 30 to cut the pipe at the through hole 1.

[0023] like Figure 1, 3 As shown, the saw blade cutting device 20 includes a first electric cylinder 2, a cutting saw blade 3, and a cutting motor 4. The first electric cylinder 2 is driven by the cutting saw blade 3 and is used to drive the cutting saw blade 3 to move inward toward the through hole 1 for cutting and to move outward toward the through hole 1 for cutting. The cutting motor 4 is driven by the cutting saw blade 3 and is used to drive the cutting saw blade 3 to rotate around its own axis. The rotating cutting saw blade 3 can cut the pipe at the through hole 1 when cutting.

[0024] The saw blade cutting device 20 also includes a first transmission mechanism 5, which is connected between the first electric cylinder 2 and the cutting saw blade 3. The first transmission mechanism 5 includes a saw blade support shaft 51 perpendicular to the mounting plate 10, a saw blade arm 52 rotatably mounted on the mounting plate 10 via the saw blade support shaft 51, and a motor base plate 53 connected to the saw blade arm 52. The cutting motor 4 is mounted on the motor base plate 53. One end of the saw blade arm 52 is hinged to the first electric cylinder 2, and the cutting saw blade 3 is rotatably mounted on the other end of the saw blade arm 52. When the telescopic rod of the first electric cylinder 2 extends or retracts, the saw blade arm 52 rotates around the saw blade support shaft 51, thereby driving the cutting saw blade 3 to move to the inside of the through hole 1 or to the outside of the through hole 1.

[0025] like Figure 1 , 2 As shown, the saw blade cutting device 20 also includes an adjusting seat 6, which is tractively connected between the mounting plate 10 and the first electric cylinder 2. The first electric cylinder 2 can move back and forth in a straight line via the adjusting seat 6. The adjusting seat 6 can adjust the position of the first electric cylinder 2 on the mounting plate 10, thereby adjusting the feed rate of the cutting saw blade 3. The adjusting seat 6 includes a seat body 61, a guide rail 62 extending in a straight line, a slider 63 that slides with the guide rail 62, a lead screw 64 connected to the slider 63, and a lead screw nut 65 mounted on the seat body 61. The lead screw 64 and the lead screw nut 65 are threadedly connected, and the cylinder body of the first electric cylinder 2 is hinged to the slider 63.

[0026] A belt drive connection is established between the cutting motor 4 and the cutting saw blade 3. A belt drive mechanism 7 connects the cutting motor 4 and the cutting saw blade 3. The belt drive mechanism 7 includes a first pulley 71, a second pulley 72, and a belt 73 simultaneously tensioned on the first pulley 71 and the second pulley 72. The first pulley 71 is coaxially mounted on the drive shaft of the cutting motor 4, and the second pulley 72 is coaxially mounted with the cutting saw blade 3. When the cutting motor 4 starts, the belt drive mechanism 7 transmits power from the cutting motor 4 to the cutting saw blade 3, causing the cutting saw blade 3 to rotate around its own axis, thereby improving the cutting efficiency of the pipe at the through hole 1. In this embodiment, the cutting saw blade 3 is a circular blade with a circumferential ring of serrations.

[0027] like Figure 1 , 3As shown, the chipless cutting device 30 includes a second electric cylinder 8 and a cutting tip 9. The second electric cylinder 8 is connected to the cutting tip 9 in a transmission manner and is used to drive the cutting tip 9 to move inward to the inside of the through hole 1 to advance the cutting tip and to move outward to the outside of the through hole 1 to retract the cutting tip.

[0028] The chipless cutting device 30 also includes a second transmission mechanism 11, which is driven between the second electric cylinder 8 and the cutting tip 9. The second transmission mechanism 11 includes a tip support shaft 111 perpendicular to the mounting plate 10 and a chipless rotating arm 112 rotatably mounted on the mounting plate 10 via the tip support shaft 111. One end of the chipless rotating arm 112 is hinged to the second electric cylinder 8, and the other end of the chipless rotating arm 112 is connected to the cutting tip 9. When the telescopic rod of the second electric cylinder 8 extends or retracts, the chipless rotating arm 112 rotates around the tip support shaft 111, thereby driving the cutting tip 9 to move to the inside of the through hole 1 or to the outside of the through hole 1. In this embodiment, the cutting tip 9 is a blade with a triangular tip.

[0029] The control system is connected to the first electric cylinder 2, the cutting motor 4, and the second electric cylinder 8. Based on the pipe specifications and current working conditions, the control system selectively controls either the saw blade cutting device 20 or the chipless cutting device 30 to advance or retract. In this application, the chipless cutting device 30 is preferentially controlled to advance and cut the pipe. When the current pipe material or working conditions are unsuitable for chipless cutting, the saw blade cutting device 20 is controlled to advance and cut the pipe. The control system adjusts the cutting saw blade 3 and the cutting tip 9 by controlling the first cylinder 2 and the second electric cylinder 8, thus enabling it to cut pipes of different diameters. The control system also includes a control panel that displays various operating parameters of the chipless cutting machine. The operator can also adjust the feed rate and speed of the cutting saw blade 3 and the cutting tip 9 through the control panel.

[0030] The first electric cylinder 2 and the second electric cylinder 8 help stabilize the feed and retraction of the cutting saw blade 3 and the cutting tip 9, improve the stability of the cutting process, and can adjust the feed amount in time to cut pipes of different specifications. The electric cylinder drives the blade to cut, which strengthens the cutting intensity and makes it suitable for cutting pipes with thick walls, thus expanding the applicability of the equipment.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
