Description

Technical Field

[0001] The present invention relates to a cutting device, in particular to a cutting device used for processing metal square tubes, which is applied in the technical field of metal tube processing. Background Art

[0002] Metal square tubes are rectangular pipes made of metal and are widely used in building steel structures, machinery manufacturing, and industrial equipment. During the production and processing of metal square tubes, it is often necessary to use a cutting device to cut long tubes into short tubes of the target length according to the requirements.

[0003] Chinese patent publication number CN112091314B discloses a metal tube cutting device that can automatically cut multiple batches of long metal tubes, unloading the material once until the cutting is completed, without the need for manual repetitive operations. At the same time, the cut section is not easily pulled by the mass at both ends to form burrs and notches.

[0004] Chinese patent publication number CN110315129B discloses a metal pipe cutting device. In this invention, a second clamping mechanism is used to continuously rotate the metal pipe during the cutting process. The cutting point on the metal pipe continuously changes during the circumferential motion, which reduces the shrinkage and burr burrs caused by thermal deformation of the cut and unidirectional cutting feed force at the same cutting point.

[0005] In existing technologies, although improvements and upgrades have effectively reduced the occurrence of burrs on cuts, burrs can still appear over time due to tool wear, equipment parameter deviations, process loss of control, and other reasons. If these burrs are not discovered and repaired and maintained in a timely manner, large quantities of square tubes with burrs will be produced, seriously affecting processing quality. However, existing cutting devices generally lack corresponding detection and warning mechanisms, making it impossible to detect and resolve problems in a timely manner.

[0029] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0030] The first implementation method:

[0031] Figure 1-Figure 5 A cutting device for processing metal square tubes is shown, comprising a processing table 101, a two-axis moving assembly 102, a cutting assembly 103, a cutting control system, and a solid tube inspection and cutting assembly. The cutting assembly 103 is used to cut the metal square tube. The two-axis moving assembly 102 is used to drive the cutting assembly 103 to move and adjust. The cutting control system is used to control the two-axis moving assembly 102 and the cutting assembly 103. The two-axis moving assembly 102 is fixedly mounted on the processing table 101. The solid tube inspection and cutting assembly includes a movable tube plate 201. A sealing cylinder 202 is fixedly mounted on the side of the movable tube plate 201 away from the cutting assembly 103. A drive inspection cylinder 203 is fixedly mounted in the sealing cylinder 202. The output end of the drive inspection cylinder 203 is fixedly connected to a sliding seal with the sealing cylinder 202. The piston plate 204 is connected, and an air guide pipe 205 is embedded in the movable tube plate 201. The air guide pipe 205 is connected to the sealing cylinder 202. A pressure sensor 206 fixedly mounted on the inner wall of the sealing cylinder 202 is provided on the side of the piston plate 204 away from the inspection cylinder 203. A square pipe support block 207 is sleeved on the outer wall of the air guide pipe 205. The pipe support block 207 is located on the side of the movable tube plate 201 away from the sealing cylinder 202. The processing table 101 is provided with an electric slide rail 104 for driving the movable tube plate 201 to move horizontally. The top of the processing table 101 is provided with a fixed tube plate 301 that matches the movable tube plate 201. The cutting assembly 103 is located on the side of the fixed tube plate 301 close to the movable tube plate 201;

[0032] The solid pipe inspection and cutting component also includes an inspection and cutting control system, which includes an inspection and cutting setting module, an inspection and cutting control module, an inspection and cutting analysis module, and a bell reminder module. The inspection and cutting setting module and the cutting control system are both signal-connected to the inspection and cutting control module, the inspection and cutting control module is signal-connected to the drive cylinder 203 and the electric slide rail 104, the air pressure sensor 206 is signal-connected to the inspection and cutting analysis module, and the inspection and cutting analysis module is signal-connected to the bell reminder module and the cutting control system.

[0033] When cutting a metal square tube, one end of the square tube is placed on the tube support block 207, and the electric slide rail 104 is controlled to drive the movable tube plate 201 to move toward the fixed tube plate 301 until the other end of the square tube abuts against the fixed tube plate 301. The target length is input through the inspection and cutting setting module, and the target length is input to the cutting control system. The cutting control system will control the two-axis moving component 102 to drive the cutting component 103 to move and adjust in the horizontal direction so that the distance between the cutting component 103 and the fixed tube plate 301 matches the target length. Then the cutting control system will start the cutting component 103 and control the two-axis moving component 102 to drive the cutting component 103 to move downward to cut the square tube. After the cutting is completed, The cutting control system controls the cutting assembly 103 to drive the two-axis moving assembly 102 to move upward and reset (the cut square tube will fall downward onto the processing table 101), and sends a signal to the inspection and cutting control module. After receiving the signal, the inspection and cutting control module controls the electric slide 104 to drive the movable tube plate 201 to move in the direction close to the fixed tube plate 301, and the moving distance matches the target length, so that the remaining square tubes are again against the fixed tube plate 301. Then, the inspection and cutting control module controls the driving and inspection cylinder 203 to drive the piston plate 204 to move in the direction close to the air guide tube 205, so as to fill the inside of the square tube with air through the air guide tube 205, thereby increasing the air pressure inside the square tube and on the side of the piston plate 204 away from the driving and inspection cylinder 203.

[0034] The air pressure sensor 206 is used to collect air pressure data, and the collected air pressure data will be transmitted to the inspection and cutting analysis module in real time. If the incision (that is, the end of the square tube that is in contact with the fixed tube plate 301 at this time) has no burrs, the square tube can be completely fitted with the fixed tube plate 301, and the two ends of the square tube are respectively sealed by the movable tube plate 201 and the fixed tube plate 301, so that after the piston plate 204 moves, the air pressure data collected by the air pressure sensor 206 will be relatively stable and will not fluctuate too much. On the contrary, if the incision has burrs, the square tube cannot be completely fitted with the fixed tube plate 301, which will cause air leakage. After the piston plate 204 moves, the air pressure data collected by the air pressure sensor 206 will show an obvious trend of gradually decreasing. Therefore, the inspection and cutting analysis module can determine whether the incision has burrs by analyzing the air pressure data collected by the air pressure sensor 206, so that the fixed pipe inspection and cutting component can automatically detect whether the incision has burrs after each cutting.

[0035] When the detection result is that there is no burr, the inspection and cutting analysis module will send a feedback signal to the cutting control system, and the cutting control system will control the two-axis moving component 102 and the cutting component 103 to continue cutting the square tube, and repeat this process until the cutting of this square tube is completed or the detection result is that there is a burr; when the detection result is that there is a burr, the inspection and cutting analysis module will control the ring reminder module to emit a corresponding prompt sound to remind the relevant technical personnel, prompting the relevant technical personnel to perform corresponding inspection and maintenance work in time and solve the existing problems in time; therefore, the present application uses the combined setting of the solid pipe inspection and cutting component, etc., so that the solid pipe inspection and cutting component can automatically detect whether there is a burr on the incision after each cutting, and can issue a reminder when the incision is detected to have a burr, so that the problem can be discovered in time and the relevant technical personnel can solve the problem in time, thereby effectively ensuring the processing quality. In addition, the solid pipe inspection and cutting component also has the function of fixing the metal square tube, and adopts a combination of internal support and tightness at both ends to fix the metal square tube, which not only supports the detection but also does not cause deformation of the square tube.

[0036] A connecting hole matching the air guide tube 205 is provided in the middle of the support tube block 207. The support tube block 207 is sleeved on the outer wall of the air guide tube 205 through the connecting hole, and the support tube block 207 is threadedly connected to the air guide tube 205, so that the support tube block 207 is easy to replace. The support tube block 207 is provided with a variety of different specifications according to the size of its outer contour. Support tube blocks 207 of different specifications correspond to metal square tubes of different specifications, so that the fixed tube inspection and cutting assembly can be adaptively adjusted according to the size of the metal square tube.

[0037] The top of the movable tube-supporting plate 201 is fixedly connected to an L-shaped support plate 208, on which a tube-pressing cylinder 209 is fixedly installed, and an output end of the tube-pressing cylinder 209 is fixedly connected to a tube-pressing plate 210, which is located above the tube-supporting block 207. After one end of the square tube is sleeved onto the tube-supporting block 207 and the other end of the square tube is abutted against the fixed tube-supporting plate 301, the tube-pressing cylinder 209 is controlled to drive the tube-pressing plate 210 to move downward until the tube-pressing plate 210 abuts against the square tube. This not only strengthens the fixing effect of the square tube, but also effectively prevents the square tube from rotating during the cutting process.

[0038] A support box 302 is fixedly installed on the top of the processing table 101, and a pressure sensor 303 is fixedly installed in the support box 302. A force transmission rod 304 is fixedly connected to the side of the fixed tube plate 301 close to the support box 302. The force transmission rod 304 passes through the outer wall of the support box 302 and extends to abut against the pressure sensor 303, and the force transmission rod 304 is slidably connected to the outer wall of the support box 302.

[0039] The support box 302 is located on the side of the fixed tube plate 301 away from the movable tube plate 201. The fixed tube plate 301 is movably connected to the processing table 101. The pressure sensor 303, the inspection and cutting setting module, and the inspection and cutting control module are all connected to the inspection and cutting analysis module by signal. When one end of the square tube is in contact with the fixed tube plate 301, the support box 302, the pressure sensor 303, and the force transmission rod 304 can jointly play a fixing effect on the fixed tube plate 301. On the one hand, it can ensure the fixing effect of the square tube, and on the other hand, it can ensure the smooth and accurate performance of the detection. In addition, under normal circumstances, when the square tube is in contact with the fixed tube plate 301, a pressure is applied to the fixed tube plate 301, causing the pressure data detected by the pressure sensor 303 to change significantly. The pressure data detected by the pressure sensor 303 will be transmitted to the inspection and cutting analysis module in real time.

[0040] During the processing, when there is a problem with the accuracy of the electric slide 104, resulting in the actual travel length of the square tube being less than the target length, the square tube will not be able to abut against the fixed tube plate 301, which will not cause a significant change in the pressure data detected by the pressure sensor 303. The inspection and cutting analysis module can discover this situation by analyzing the pressure data detected by the pressure sensor 303 (after the inspection and cutting control module controls the electric slide 104 to drive the movable tube plate 201 to move, it will send a corresponding signal to the inspection and cutting analysis module). At this time, the inspection and cutting analysis module will control the ringing reminder module to emit a corresponding prompt sound to remind relevant technicians. On the one hand, the accuracy problem of the electric slide 104 can be discovered in time. On the other hand, the failure of the square tube to abut against the fixed tube plate 301 will cause the detection to be unable to proceed smoothly. Discovering this problem in time and giving a reminder can prompt relevant technicians to maintain the electric slide 104 in time, which is conducive to ensuring the accuracy and reliability of the detection.

[0041] In addition, a pressure threshold is reasonably set through the inspection and cutting setting module. When the actual travel length of the square tube is greater than the target length, the pressure data will exceed the pressure threshold. At this time, the inspection and cutting analysis module will also control the ringing reminder module to emit a corresponding prompt sound to remind relevant technical personnel. At the same time, the inspection and cutting analysis module will also send a signal to the inspection and cutting control module to make the inspection and cutting control module control the electric slide 104 to stop moving; therefore, through the joint setting of the solid pipe inspection and cutting component, the fixed tube plate 301, the pressure sensor 303, etc., when there is a problem with the accuracy of the electric slide 104, resulting in the actual travel length of the metal square tube not matching the target length, the solid pipe inspection and cutting component will also promptly discover this problem and issue a reminder. On the one hand, it can ensure the accuracy and reliability of the detection, and on the other hand, it can ensure the cutting accuracy, thereby further ensuring the processing quality.

[0042] Second implementation method:

[0043] Figure 6-Figure 8 The invention shows a cutting device for processing metal square tubes. Different from the first embodiment, a tube pushing and slow delivery assembly is further provided on the processing table 101. The tube pushing and slow delivery assembly includes a support frame 401 and a catheter seat 404 fixedly mounted on the processing table 101. The support frame 401 and the catheter seat 404 are respectively located on the left and right sides of the cutting assembly 103. The support frame 401 is set in an L shape, and the catheter seat 404 is set in a U shape. The catheter seat 404 is tilted. A tube pushing cylinder 402 is fixedly mounted on the support frame 401. The output end of the tube pushing cylinder 402 is fixedly connected to the tube pushing slide 40 3. The tube pushing slide 403 is located above the processing table 101. A tube blocking plate 405 that matches the tube seat 404 is movably provided at one end away from the processing table 101. A horizontal plate 406 is fixedly installed on the top of the tube seat 404. A control and blocking cylinder 407 is fixedly installed on the horizontal plate 406. A linkage plate 408 is fixedly connected between the control and blocking cylinder 407 and the tube blocking plate 405. The inspection and cutting control system also includes a push-and-slow control module. The push-and-slow control module is signal-connected to the tube pushing cylinder 402 and the control and blocking cylinder 407. The inspection and cutting control module and the inspection and cutting analysis module are signal-connected to the push-and-slow control module.

[0044] The inspection and cutting control module has two detection modes: continuous detection and interval detection. The interval parameters and mode switching parameters are set through the inspection and cutting setting module. When the cutting device is running, the inspection and cutting control module first runs in the continuous detection mode. After each cut, the inspection and cutting control module will control the solid pipe inspection and cutting component to perform the detection operation. When the number of detections reaches the mode switching parameter and the detection results are all without burrs, it will automatically switch to the interval detection mode. In the interval detection mode, the inspection and cutting control module will perform a detection operation every few cuts according to the interval parameter. When the detection operation is not performed, after each cut, the inspection and cutting control module will only control the electric slide 104 to drive the movable tube plate 201 to move so that the square tube and the fixed tube plate 301 are abutted. In this way, it can ensure that when there are burrs on the cut, they can be discovered in time, and the cutting efficiency can be effectively improved, thereby improving the intelligence of the cutting device.

[0045] After the cutting is completed, the cut square tube is generally transported to the next process through a conveyor belt, and the conveyor belt is set below the end of the catheter seat 404 away from the processing table 101. After each cutting, the cutting control system will also send a signal to the push-down control module. After receiving the signal, the support frame 401 will control the tube pushing cylinder 402 to push the tube pushing slide 403 to push the cut square tube to the catheter seat 404. In the continuous detection mode, the support frame 401 will control the control stop cylinder 407 to drive the tube stop plate 405 to move upward to make the square tube The tube can slide along the catheter seat 404 onto the conveyor belt. In the interval detection mode, there may be square tubes with burrs between two inspections. In order to prevent the square tubes with burrs from flowing into the next process, when the mode is switched to the interval detection mode, the inspection and cutting control module will send a signal to the push-down control module, causing the push-down control module to control the control cylinder 407 to drive the tube blocking plate 405 to move downward and reset, so as to block the end of the catheter seat 404 away from the processing table 101, thereby temporarily storing the square tubes cut between the two inspections in the catheter seat 404. In the interval detection mode, each time the detection is completed and the detection result is that there is no burr, the inspection and cutting analysis module will send a signal to the push-down control module, causing the push-down control module to control the control cylinder 407 to drive the tube baffle plate 405 to move upward, so that the square tube temporarily stored in the catheter seat 404 can fall onto the conveyor belt, and the push-down control module will control the control cylinder 407 to drive the tube baffle plate 405 to move downward and reset before the next control of the tube pushing cylinder 402 to push the tube pushing slide 403, thereby effectively preventing the square tube with burrs from flowing into the next process. Therefore, through the joint setting of the push-and-slow control module, the push-and-slow tube conveying component, etc., the solid tube inspection and cutting component has two different detection modes, and the detection mode can be switched automatically and intelligently, thereby ensuring the reliability and timeliness of the detection and improving the processing efficiency. The push-and-slow tube conveying component can automatically push the cut square tube onto the conveyor belt, and the push-and-slow tube conveying component will also make intelligent adjustments as the mode is switched, thereby effectively preventing the square tube with burrs from being conveyed to the next process, greatly improving the intelligence and practicality of the cutting device.

[0046] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
