Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, in particular to a PE pipe cutting device. Background Art

[0002] PE pipes are widely used. Water pipes and gas pipes are the two largest application markets. PE pipes are also a replacement product for traditional steel pipes and polyvinyl chloride drinking water pipes.

[0003] After the PE pipe is processed, it needs to be cut as needed to be used in the corresponding scene. Therefore, in the secondary processing of the PE pipe, it is often necessary to cut the PE pipe in sections, and the cutting operation of the section cutting is relatively frequent, and the cutting operation will be performed continuously. This process will involve the positioning of the cutting length of the PE pipe, the feeding and unloading of the pipe fittings during the cutting process, and the use of the cutting wheel alone plus the above operations will result in very low work efficiency. In addition, the long-term use of the handheld cutting wheel will also cause hand fatigue. Long-term use is prone to accidental injuries caused by improper operation, and safety protection is needed during the cutting process to prevent the ends of the pipe fittings from flying off after being cut and injuring the operator. In order to solve the above problems, it is necessary to design a PE pipe cutting device. Utility Model Content

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] See also Figure 1-2 , a PE pipe cutting device, comprising:

[0043] Work surface 1, so that the PE pipe cutting operation is carried out on the work surface 1;

[0044] A push-type cutting mechanism is arranged on a work surface 1 for cutting PE pipes. The push-type cutting mechanism comprises a cutting wheel 2 and a rebound-type push-drive mechanism for driving the cutting wheel 2 to push forward to cut the PE pipe. An avoidance groove 3 for avoiding the cutting wheel 2 tool is arranged on the upper surface of the work surface 1. In order to make the movement of the cutting wheel 2 during the cutting process on the work surface 1 more stable, while the cutting wheel 2 is fed by the rebound-type push-drive mechanism, the cutting wheel 2 can also be moved through a linear track. Specifically, the outer shell or base of the cutting wheel 2 is fixed on the slider of the linear track by fastening bolts and other accessories, so that the cutting wheel 2 can cut the PE pipe when moving forward, and the avoidance groove 3 is used to avoid the cutting tool from feeding;

[0045] A feeding mechanism, which is arranged on the work surface 1 and located on one side of the push-type cutting mechanism, is used to feed the PE pipe to the cutting wheel 2 of the push-type cutting mechanism, so that the feeding operation can be conveniently and quickly performed during the continuous cutting process of the PE pipe, thereby improving the overall work efficiency; and

[0046] The material pushing mechanism is arranged on the upper surface of the work surface 1 and is located on the side of the push-type cutting mechanism opposite to the feeding mechanism to push the cut PE pipe out of the material.

[0047] Furthermore, the rebound-type propulsion drive mechanism includes:

[0048] A connecting frame 4, which is a rectangular frame structure and is laterally connected to the cutting wheel 2 on a side opposite to the cutter head;

[0049] A first guide tube 5 is vertically arranged on the connecting frame 4 on a side opposite to the cutting wheel 2, and an axis extension direction of the first guide tube 5 is consistent with a feed direction of the cutting wheel 2;

[0050] A first push rod 6 is coaxially arranged in the first guide tube 5 and continues to extend to pass through one side of the connecting frame 4 to extend into the inner side of the connecting frame 4. The first push rod 6 slides in the first guide tube 5. One end of the first push rod 6 extending into the inner side of the connecting frame 4 is connected to a pressing plate 7. A first compression spring 8 is arranged between a side of the pressing plate 7 opposite to the first push rod 6 and the inner side surface of the connecting frame 4; and

[0051] An operating handle 9 is provided on an end of the first push rod 6 opposite to the connecting frame 4 .

[0052] Specifically, the first push rod 6 is controlled by the operating handle 9 to move in the first guide tube 5 and through the connecting frame 4, and the pressure plate 7 compresses the first compression spring 8 and then continues to push to push the cutting wheel 2 connected to the connecting frame 4 to move forward for feed cutting. The first compression spring 8 in the middle plays a shock absorbing role, which reduces the vibration of the cutting wheel 2 during the feed cutting process and causes discomfort to the hand. In addition, during the process of driving the cutting wheel 2 by the entire rebound propulsion drive mechanism, the cutting wheel 2 is not directly contacted, so that there is a safe distance between the hand and the cutting wheel 2 to avoid accidental injury.

[0053] Further, the feeding mechanism comprises:

[0054] An assembly transverse plate 10 is horizontally arranged above the work surface 1. Support plates 11 are arranged on both sides of the assembly transverse plate 10 in the PE pipe feeding direction to fix the assembly transverse plate 10 above the work surface 1;

[0055] A feeding roller structure, which is arranged on the assembly transverse plate 10 and is used to drive the PE pipe to move axially and feed the material through the friction between the feeding roller structure and the PE pipe when the feeding roller structure rolls; and

[0056] The rotation driving mechanism is arranged on the assembly transverse plate 10 to drive the feeding roller structure to rotate.

[0057] Specifically, the feed roller structure is driven to rotate by a rotating drive mechanism, so that the friction between the feed roller structure and the PE pipe when rolling drives the PE pipe to move axially for feeding, so the assembly cross plate 10 plays the role of installing and supporting the feed roller structure and the rotating drive mechanism.

[0058] Further, the feeding roller structure comprises:

[0059] An assembly opening 12, which is provided on the assembly horizontal plate 10;

[0060] A main rotating roller 13, which is horizontally arranged inside the assembly opening 12;

[0061] An outer elastic sleeve 14, which is sleeved on the outer side of the main rotating roller 13; and

[0062] The elastic support column 15 is connected between the inner surface of the outer elastic sleeve 14 and the circumferential surface of the main rotating roller 13 to elastically support the outer elastic sleeve 14 .

[0063] Specifically, the outer elastic sleeve 14 is supported by the elastic support column 15 on the main rotating roller 13, so that the outer elastic sleeve 14 rotates with the main rotating roller 13, so that it passes through the assembly opening 12 and is elastically pressed on the PE pipe passing through the two groups of support plates 11 below the assembly cross plate 10, so that when the outer elastic sleeve 14 rotates with the main rotating roller 13, the friction force is used to drive the PE pipe to feed and move.

[0064] Furthermore, the outer elastic sleeve 14 is an anti-slip rubber elastic layer, so that the outer elastic sleeve 14 has higher friction and elastic deformation ability. When pressed on the PE pipe, the part of the outer elastic sleeve 14 pressed on the PE pipe is concave inward, and at the same time, the elastic support column 15 is elastically deformed to make the outer elastic sleeve 14 elastically pressed on the PE pipe, which also has the effect of increasing friction, and is more stable in the subsequent driving process of the PE pipe to move.

[0065] Furthermore, the rotation drive mechanism includes a horizontal shaft 16, which is horizontally arranged above the work surface 1 and rotatably arranged on the assembly horizontal plate 10 through a bearing. The horizontal shaft 16 is coaxially arranged on the main rotating roller 13, and one end of the horizontal shaft 16 extends outward to the end outside the assembly horizontal plate 10 to be provided with a driving turntable 17. The driving turntable 17 is rotated by manually driving the horizontal shaft 16 to rotate, thereby driving the main rotating roller 13 to rotate.

[0066] Furthermore, the material pushing mechanism includes:

[0067] A second guide tube 18 is horizontally arranged on the upper surface of the work surface 1 and is arranged perpendicular to the feeding direction of the PE tube;

[0068] A second push rod 19 is coaxially disposed in the second guide tube 18 and slides in the second guide tube 18. One end of the second push rod 19 facing the PE tube is connected to a push plate 20, and the other end is connected to a push button 21;

[0069] A second compression spring 22, which is sleeved on the second push rod 19 and compressed between the second guide tube 18 and the push button 21; and

[0070] The anti-falling protection plate 23 is arranged at the upper end of the push plate 20 and is located above the PE pipe.

[0071] Specifically, after the PE tube is cut, the push button 21 is manually pressed to drive the second push rod 19 to move axially in the second guide tube 18, and the second compression spring 22 is compressed, and the axial movement of the second push rod 19 also drives the push plate 20 to move, so that the cut PE tube is pushed out by the push plate 20 to complete the unloading. The anti-collision protection plate 23 at the upper end of the push plate 20 is always above the PE tube, which can intercept the PE tube above and prevent the end of the cut PE tube from collapsing and injuring people.

[0072] Furthermore, a limiting top plate 24 is provided on the upper surface of the work surface 1 on the side opposite to the feeding mechanism, so as to limit the feeding distance of the PE pipe through the limiting top plate 24, so as to quickly locate the cutting position of the PE pipe, which is convenient and quick. In another embodiment, the position of the limiting top plate 24 can be adjusted on the upper surface of the work surface 1, and with a ruler, the quick positioning and adjustment of the cutting length of the PE pipe can be more flexibly adjusted.

[0073] Furthermore, a PE pipe limiting channel 25 is provided on the upper surface of the workbench 1 on the side opposite to the limiting top plate 24. The PE pipe limiting channel 25 enables the PE pipe to pass through, and mainly serves to limit the processing position of the PE pipe, so as to prevent the position of the PE pipe from changing during the processing and affecting the processing accuracy.

[0074] To sum up, the utility model is a PE pipe cutting device. This device uses a push-type cutting mechanism and a rebound push-type driving mechanism to drive the cutting wheel to feed and cut the PE pipe. The operation is convenient and labor-saving, and accidental injuries can be avoided. The PE pipe is fed by the feeding mechanism and the cut material is pushed out by the material pushing mechanism, making the whole operation process convenient and fast with high work efficiency. The above mechanisms can also effectively limit the position of the PE pipe to avoid the situation where the end of the pipe falls off and injures people, making it safer and more efficient to use.

[0075] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
