Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, specifically to an automated and precise cutting device for metal pipes. Background Technology

[0002] Metal pipe fittings often require cutting during processing to meet the dimensional requirements of different applications. Traditional cutting methods rely heavily on manual operation, resulting in low efficiency, difficulty in guaranteeing cutting accuracy, and high labor intensity. With the development of automation technology, some automated cutting equipment has emerged on the market, improving processing efficiency to a certain extent. Taking a metal pipe fitting automated precision cutting device disclosed in patent CN221110910U as an example, this device uses a fixed plate. Before cutting, the metal pipe is placed on top of a support roller. Then, the lifting frame is pulled to lower the internal rubber wheels, making them fit against the top of the metal pipe. The positioning bolt is then rotated to insert it into the slot and align it with the top of the limiting post, thus positioning the lifting frame at the top. A second drive motor is then activated to rotate a set of connecting shafts. These connecting shafts, through sprockets and chains, drive two sets of rubber wheels to rotate synchronously. The rotation of the rubber wheels against the outside of the metal pipe quickly pushes the pipe to one side, transporting it to the cutting position. This solves the problem of not being able to automatically transport pipe fittings. However, the existing equipment still has some obvious shortcomings: for example, some equipment has a relatively simple function, only able to complete the cutting operation, and lacks the ability to automatically process the end face of the cut pipe fittings; especially after the cutting is completed, burrs, flash and other defects are easy to be generated at the cut of the pipe fittings, which not only affect the appearance and quality of the product, but may also cause scratches to the subsequent operators. Utility Model Content

[0015] The present invention will be further described below with reference to the embodiments.

[0016] Example: Refer to Figures 1 to 5 An automated precision cutting device for metal pipe fittings, comprising: Fixed platform 1; Lifting assembly 2, which includes a locking block 210 that is elastically and slidably installed within the fixed platform 1; Cleaning component 3 includes a top plate 301 fixedly installed on the upper end of the card block 210. A vertical plate 302 is fixedly installed on the upper surface of the top plate 301. An air inlet pipe 303 is fixedly installed on one side of the vertical plate 302. A partition 305 is airtightly and slidably installed on the inner wall of the air inlet pipe 303. A fourth spring is fixedly installed between the partition 305 and the air inlet pipe 303. A transmission rod 306 is airtightly and rotatably installed inside the partition 305. One end of the transmission rod 306 passes through the vertical plate 302 and is fixedly installed with a brush head. Multiple fan blades 307 are fixedly installed in a circumferential array on the outer wall of the partition 305 at a position away from the brush head.

[0017] Reference Figure 1 A fixing block 101 is fixedly installed on the upper surface of the fixing platform 1. A rotating rod 102 is rotatably installed on one side of the fixing block 101. A cutting machine 103 is fixedly installed on one side of the rotating rod 102.

[0018] Reference Figures 2 to 3 A first fixing box 201 is fixedly installed on the upper surface of the fixing platform 1. A lifting rod 202 is airtightly slidably installed inside the first fixing box 201. The upper end of the lifting rod 202 passes through the first fixing box 201 and is in contact with the rotating rod 102. A first spring 208 is fixedly installed between the lifting rod 202 and the fixing platform 1. A solenoid valve 205 is fixedly installed inside the fixing platform 1 at a position corresponding to the first fixing box 201. An elastic box 204 is embedded inside the fixing platform 1 at a position corresponding to the first fixing box 201. The metal tube to be cut is then placed inside the fixing platform 1. The part is placed on the cutting machine 103, and one end of it is fixed to the placement platform 213 by passing through the locking block 210. By rotating the rotating rod 102, the cutting machine 103 is driven to descend to the surface of the pipe. The cutting machine 103 is started to complete the cutting operation. During the rotation and descent of the rotating rod 102, its lower end will squeeze the lifting rod 202, causing the lifting rod 202 to slide downward in the first fixed box 201 and compress the first spring 208. At this time, the air in the first fixed box 201 is compressed, the air pressure gradually increases, and pushes the elastic box 204 to expand.

[0019] Reference Figures 2 to 3A second fixed box 203 is fixedly installed on the lower end face of the fixed platform 1 at the position corresponding to the first fixed box 201. The outer side of the second fixed box 203 is provided with an air vent. A lifting plate 206 is airtightly slidably installed on the inner wall of the second fixed box 203. A second spring 209 is fixedly installed between the lifting plate 206 and the second fixed box 203. A linkage bracket 207 is fixedly installed on the lower end face of the lifting plate 206. The lower end of the linkage bracket 207 passes through the second fixed box 203 and is fixedly connected to the lower end of the locking block 210. Reference Figures 4 to 5 External plates 211 are fixedly installed on both sides of the clamping block 210. A third spring 212 is fixedly installed between the external plate 211 and the fixed platform 1. A placement platform 213 is fixedly installed on one side of the external plate 211. After cutting, the rotating rod 102 is kept in a downward posture. The solenoid valve 205 is opened to release the high-pressure air in the first fixed box 201 into the second fixed box 203 through the flow pipe 308. The high-pressure air pushes the lifting plate 206 to slide downward and compress the second spring 209. The lifting plate 206 drives the clamping block 210 and its connecting parts to descend as a whole through the linkage bracket 207. When the clamping block 210 descends, the external plate 211 compresses the third spring 212, so that the cut pipe is lowered accordingly, which facilitates subsequent removal of the part.

[0020] Reference Figures 4 to 5 A card holder 309 is fixedly installed inside the fixed platform 1 and on one side of the card block 210. A sliding groove 310 is opened inside the card holder 309. A card is fixedly installed on the outer wall of the transmission rod 306. The card is slidably connected to the sliding groove 310.

[0021] Reference Figures 4 to 5 An air inlet 304 is provided on the outer wall of the air inlet pipe 303. One end of the air inlet pipe 303 is connected to a flow pipe 308, and one end of the flow pipe 308 is connected to the first fixed box 201. A one-way valve is fixedly installed on the inner wall of the flow pipe 308. When the locking block 210 descends, it will cause the cleaning assembly 3 to move down as a whole. The air inlet pipe 303 and the transmission rod 306 will descend accordingly. The card on the outer wall of the transmission rod 306 slides along the slide groove 310 of the card holder 309 and extends forward under the action of the fourth spring, so that the brush head is in contact with the end face of the cut pipe. Upon contact, the rotating rod 102 drives the cutting machine 103 to rise. At this time, the solenoid valve 205 is closed, and the second fixed box 203 maintains a high pressure state to prevent the lifting plate 206 from rebounding. As the rotating rod 102 rises, the first spring 208 pushes the lifting rod 202 to move upward, and the air pressure in the first fixed box 201 rises again. Outside air enters the air intake pipe 303 through the air inlet 304, driving the fan blade 307 to rotate, which in turn drives the transmission rod 306 and the brush head to rotate, performing burr cleaning operations on the cut end face of the pipe fitting.

[0022] The working principle of this utility model is as follows: Place the pipe fitting onto the cutting machine 103, pass one end of the pipe fitting through the clamping block 210 and place it into the placement platform 213. Rotate the rotating rod 102 to lower the cutting machine 103, and then turn on the cutting machine 103 to cut the pipe fitting. During the rotation of the rotating rod 102, it will compress the lifting rod 202, causing the lifting rod 202 to descend within the first fixed box 201 and compress the first spring 208. The compressed air will gradually increase the air pressure within the first fixed box 201, expanding the elastic box 204. After the pipe fitting is cut, continue to maintain the rotation rod 102... 02. Rotate to the lowering position, open the solenoid valve 205 to discharge the compressed air in the first fixed box 201 into the second fixed box 203. This causes the air-driven lifting plate 206 to slide and descend within the second fixed box 203, compressing the second spring 209. The driven lifting plate 206 will drive the linkage bracket 207 and the locking block 210 to move and descend. The descending locking block 210 will drive the outer plate 211 to descend and compress the third spring 212, thereby driving the cut pipe to descend, facilitating the subsequent removal of the cut pipe. The cutting end of the raw material will be cut... Burrs appear afterward, which can cause cuts when personnel move the raw material during continued cutting. After the clamp 210 is driven to descend, it will move the top plate 301 and the vertical plate 302 to descend as well. The descending vertical plate 302 will also move the air inlet pipe 303 down, which will in turn move the transmission rod 306 and the brush head down. The card set on the outer wall of the transmission rod 306 will slide and connect with the slide groove 310 and be compressed by the elastic force of the fourth spring, extending forward to contact the side of the cutter head. At this time, rotating the rotating rod 102 will drive the cutting machine 103 to rise (in During this process, the solenoid valve 205 is closed, keeping the second fixed box 203 under high air pressure (preventing the lifting plate 206 from rising). The brush head will contact the cutting end face of the raw material under the continuous elastic force of the fourth spring. After the rotating rod 102 rotates and rises, the compressed first spring 208 will drive the lifting rod 202 to rise, increasing the air pressure inside the lifting rod 202. Outside air will enter the air inlet pipe 303 through the air inlet 304, driving the fan blade 307 to drive the transmission rod 306 and the brush head to rotate and clean the end face of the raw material, removing the burrs generated during cutting.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
