Description

Technical Field

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

[0002] When the pipe cutting machine is cutting pipes, the high-speed rotating cutting tool is likely to generate chips when it contacts the pipe. These chips will splash around the pipe cutting machine, which may cause harm to the staff. In order to prevent the splashing of chips, the prior art generally adopts a dust suction device or a coolant spraying system to prevent the splashing of chips. Both methods can reduce the splashing of chips. The dust suction device absorbs the chips by suction, and the coolant spraying system sprays the coolant to the cutting area through the liquid feeding system. The coolant adheres the chips to the pipe, thereby reducing the splashing of chips. However, both of the above methods have shortcomings. Among them, the dust suction device is limited to the installation of the components of the pipe cutting machine and cannot be formed around the pipe. The cooling system forms an enclosed suction area, which makes the chips escape from the area with less wind, and the coolant spray system sprays coolant to the entire cutting area. The coolant is in the form of mist or rain after spraying, and the chips have a greater moving speed and penetration when they are formed. The flowing liquid layer formed by the mist or rain coolant at the cutting point cannot form a large pressure on the chips, and the chips are easy to escape from the liquid layer. Moreover, when cutting the lower half of the curved pipe such as a round pipe, it is difficult to form a liquid layer at the cutting point due to the falling of the liquid, which makes the chips more likely to splash. Both methods cannot exert a large impact force on the chips as soon as they are generated. For this reason, a pipe cutting protection device is provided. Utility Model Content

[0019] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0020] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0021] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0022] Example 1, please refer to Figure 1 to Figure 4 The structure shown, in the embodiment of the utility model, a pipe cutting protection device includes a driving source 1, a placing frame arranged on the driving source 1, and a water pump 7, the placing frame is provided with a rotating disk 4, the middle position of the rotating disk 4 is provided with a spray assembly, the spray assembly includes a moving part and a spray head 10, the moving part is used to drive the spray head 10 to move, the water pump 7 is used to supply water to the spray head 10, the spray head 10 is opposite to the contact point between the cutting knife and the pipe, and is used to spray the contact point between the cutting knife and the pipe;

[0023] The pipe cutting protection device further comprises a controller 14, wherein the controller 14 is used to control the moving speed of the nozzle 10 to be equal to the feeding speed of the cutting tool.

[0024] In this embodiment, the nozzle 10 is a high-pressure nozzle. The water flow ejected by the high-pressure nozzle has a large impact force. During the cutting process of the metal tool and the pipe, the high-speed rotating metal tool rubs against the pipe, which easily generates tiny metal chips. These chips are generated at the contact point between the metal tool and the pipe. The high-pressure nozzle is aimed at the contact point between the metal tool and the pipe. At the first time when the chips are formed, they will be subjected to the pressure of the water column ejected by the nozzle 10, making it difficult for these chips to splash outward. The chips will be suppressed by the water column, making it difficult for these chips to splash outward. Through the controller 14 set, the moving speed of the nozzle 10 can be controlled to be equal to the feed speed of the cutting knife, which can ensure that the nozzle 10 can always be aimed at the contact part between the cutting tool and the pipe, thereby ensuring that during the entire cutting process of the pipe, once the chips are generated, they will be suppressed by the water column. The water pump 7 is connected to the external water source, and the water pump 7 can be installed on the components of the pipe cutting protection device such as the placement rack, or it can be installed on the pipe cutting machine 18.

[0025] Furthermore, the placement rack includes a horizontal plate 2 and a vertical plate 3 arranged on the horizontal plate 2 , and the rotating disk 4 is arranged on the vertical plate 3 .

[0026] In this embodiment, there are two vertical plates 3, which are respectively installed at both ends of the horizontal plate 2 and are arranged opposite to each other. There are two horizontal plates 2 and two rotating disks 4, which are respectively installed on the two vertical plates 3.

[0027] Furthermore, an electromagnet 17 is disposed inside the rotating disk 4, and the electromagnet 17 is used to absorb the moving part.

[0028] Furthermore, the transverse plate 2 is arranged at the output end of the driving source 1, and the driving source 1 is used to drive the transverse plate 2 to move in the vertical direction.

[0029] In this embodiment, the driving source 1 may be a scissor lift, which can move the cross plate 2 relatively smoothly. An electric lift rod, a screw lift, etc. may also be selected as the driving source 1.

[0030] Furthermore, the moving part includes a mounting plate 6, a rotating motor 5 arranged on the mounting plate 6, and a screw rod 13 detachably connected to the output end of the rotating motor 5, a nut seat 15 is threadedly connected to the screw rod 13, and the nozzle 10 is arranged on the nut seat 15. As the rotating motor 5 is started, the screw rod 13 starts to rotate, thereby driving the nut seat 15 to move along the length direction of the screw rod 13, thereby realizing the movement of the nozzle 10. It should be noted that the moving speed of the nozzle 10 is the same as the feed speed of the cutting tool, and the initial position of the nozzle 10 is relative to the highest point of the pipe to be cut.

[0031] In this embodiment, there are two moving parts and two nozzles 10, and the two moving parts are respectively arranged on the two rotating disks 4, and the two nozzles 10 are respectively arranged on the two moving parts. A linkage rod 9 is set between the two mounting plates 6, and the mounting plate 6 is rotatably connected with the rotating disk 4 through a rotating pin 11. The whole or part of the mounting plate 6 is made of iron, wherein the part refers to the part of the mounting plate 6 close to the rotating disk 4. When the feeding direction of the cutting tool is oblique, it is necessary to rotate the mounting plate 6 so that the moving direction of the nozzle 10 is the same as the feeding direction of the cutting tool. After rotating into place, the electromagnet 17 in the rotating disk 4 is energized and has magnetism, thereby adsorbing the iron mounting plate. Plate 6, so that the mounting plate 6 will not rotate again. Considering that the mounting plate 6 can be firmly adsorbed and will not still rotate after adsorption due to weight, the portion of the mounting plate 6 close to the rotating disk 4 is made of iron, and the remaining portion is made of lightweight and hard materials such as wood or plastic. Through the linkage rod 9, the inclination angles of the two moving parts can be guaranteed to be the same. The reason for setting two nozzles 10 is that the inside of the pipe is hollow, and the cutting tool removes the highest and lowest points of the pipe when cutting the pipe. In the remaining parts, the tool and the pipe have two contact points, and the two contact points are opposite. The two nozzles 10 are respectively aimed at the two contact points, and the water columns sprayed by the two nozzles 10 respectively suppress the two contact points except for the sputtered chips.

[0032] Furthermore, a slide groove 16 is provided on the side of the mounting plate 6, and a ring 8 is slidably connected in the slide groove 16. A water pipe 12 is connected between the water outlet of the water pump 7 and the water inlet of the nozzle 10, and the water pipe 12 passes through the ring 8. The ring 8 can prevent the water pipe 12 from being entangled on the moving part during use.

[0033] Furthermore, the controller 14 is control-connected to the control module of the pipe cutting machine 18 for receiving and processing data transmitted by the control module. The driving source 1, the rotating motor 5 and the water pump 7 are all control-connected to the controller 14 for controlling the height of the placement rack, the initial position of the nozzle 10, the moving speed of the nozzle 10 and the opening and closing of the nozzle 10.

[0034] In this embodiment, the controller 14 can adopt an integrated circuit board to manage and control the pipe cutting protection device to perform various operations. The integrated circuit board usually needs to include a microprocessor, an input and output interface, a communication interface, etc., and is connected to the control module of the pipe cutting machine 18. At the beginning of pipe cutting, the rotating motor 5 is started so that the nozzle 10 is located at the highest point of the screw rod 13, the driving source 1 is started, the height of the injection assembly is adjusted so that the nozzle 10 can be aligned with the highest point of the pipe, and the water pump 7 is started so that the nozzle 10 sprays a high-pressure water column toward the pipe. As the cutting tool starts to cut the pipe, the nozzle 10 sprays water toward the contact point between the tool and the pipe. The controller 14 controls the nozzle 10 to move downward, and its moving speed is the same as the feed speed of the tool. If the feed direction of the tool is oblique, the moving part needs to be adjusted accordingly so that the electromagnet 17 is powered off, the mounting plate 6 is no longer adsorbed by the electromagnet 17, and the mounting plate 6 is rotated so that its inclination angle is the same as the feed angle of the tool. Then the electromagnet 17 is powered on to adsorb the mounting plate 6 again, and then the above-mentioned tool cutting operation is completed.

[0035] refer to Figure 4 In order to facilitate understanding of the installation and use of the protective component in the pipe cutting equipment, an exemplary pipe cutting machine 18 suitable for use with a pipe cutting protective device is proposed. The pipe cutting machine 18 includes the following mechanisms: a frame 1801, a loading component and a cutting component 1804 arranged on the frame 1801, a positioning fixture 1805 is also arranged on the frame 1801 relative to the loading component, and a protective component is arranged below the cutting component 1804. The loading component includes a roller 1802 and a V-shaped slide 1803. The roller 1802 and the V-shaped slide 1803 are arranged along the length direction of the frame 1801, and the two are positioned relative to each other, that is, the V-shaped slide 1803 is located on the extension line of the length direction of the roller 1802. The pipe is transported by the roller 1802 and stably transported to the positioning fixture 1805 through the V-shaped slide 1803.

[0036] During the pipe cutting process, the pipe is transported to the positioning fixture 1805 through the roller 1802, and the pipe is clamped by the positioning fixture 1805. According to the required pipe size, the pipe of appropriate size is transported to the positioning fixture 1805, and the pipe is cut by the cutting component 1804, thereby completing the cutting process. During the process of the metal cutting tool cutting the metal pipe, the contact part between the cutting tool and the metal pipe may splash metal chips outward, and the splashed metal chips may cause damage to the human body. The splash-proof component can prevent the metal chips from splashing onto the human body, thereby increasing the safety performance of the equipment. The protective component in the pipe cutting machine 18 is arranged below the cutting component 1804 and between the positioning fixture 1805 and the V-shaped slide 1803. Considering that the cutting tool cannot be interfered with, the space between the two nozzles 10 needs to be larger than the feeding range of the cutting tool. Considering that the pipes on different pipe cutting machines 18 have different heights above the work surface during feeding, the driving source 1 is designed to expand the moving range of the nozzle 10 and adapt to a variety of pipe cutting equipment. The driving source 1 can be set on the frame 1801 or in the frame 1801, and can be installed according to different installation environments.

[0037] In addition to the above exemplary pipe cutting machine 18, the protection component can also be set in other pipe cutting components 1804 equipment.
