[0002] In many fields such as construction engineering and bridge construction, steel bars are indispensable building materials. In the processing of steel bars, straightening and cutting are two important processes. The steel bar straightening and cutting integrated equipment is used to straighten and cut steel bars.

[0003] The invention patent with publication number CN108453198B discloses a steel bar straightening and cutting device. One end of the steel bar ring extends into the device from a guide sleeve, and passes through a straightening mechanism, a feeding mechanism, a cutting mechanism and a unloading mechanism in sequence to complete the straightening and cutting of a section of the steel bar.

[0004] The invention patent with publication number CN100469484C discloses a steel bar straightening and cutting machine, which is composed of a frame, a driving mechanism, a traction mechanism, a straightening mechanism, a shearing mechanism, and a material receiving frame. The front end of the straightening die sleeve of the straightening mechanism has a front end flared guide piece to facilitate the insertion of the steel bar.

[0005] When straightening and cutting steel bars, the stable conveying of steel bars is one of the key factors to ensure the processing quality of steel bars. However, in the actual processing, the conveying speed of steel bars will inevitably fluctuate, which may easily lead to unqualified length of cut steel bars (that is, the length of cut steel bars does not match the preset cutting length), thus affecting the processing quality. Therefore, we propose a CNC steel bar straightening and cutting integrated equipment. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that when straightening and cutting the steel bars, the conveying speed of the steel bars will inevitably fluctuate, which may easily lead to unqualified lengths of the cut steel bars.

[0007] In order to solve the above problems, the present invention provides a CNC type steel bar straightening and cutting integrated equipment, including a straightening mechanism, a traction mechanism, a cutting mechanism, a double-checking and measuring length mechanism, and a CNC cutting center. The straightening mechanism is used to straighten the steel bar, the traction mechanism is used to pull and transport the steel bar, and the cutting mechanism is used to cut the straightened steel bar. The straightening mechanism and the cutting mechanism are respectively located on both sides of the traction mechanism. The double-checking and measuring length mechanism includes a length measuring support frame arranged in an L shape, one end of the length measuring support frame is fixedly connected with a length measuring support plate, a distance sensor 1, a support tube, a checking and measuring cylinder, and a push-back cylinder are fixedly installed on the length measuring support plate, a connecting slide rod is penetrated on the outer wall of the support tube away from the end of the length measuring support plate, the connecting slide rod is slidably connected to the outer wall of the support tube, and the two ends of the connecting slide rod are respectively fixedly connected with a follow-up length measuring plate and a card block, the card block is located in the support tube and abuts against the inner wall of the support tube, and the follow-up length measuring plate is located between the cutting mechanism and the distance sensor 1;

[0008] The output end of the test cylinder is fixedly connected with a connecting plate, on which a test button is fixedly installed. The test button is a self-reset button. The adjustment and cutting CNC center is provided with an adjustment and pulling control module, a cutting control module, a parameter setting module, a length measurement analysis module, and an abnormal alarm module;

[0009] The adjustment and traction control module is used to control the straightening mechanism and the traction mechanism, the cutting control module is used to control the cutting mechanism, the parameter setting module is used to set the processing parameters, the parameter setting module is signal-connected with the adjustment and traction control module, the cutting control module, and the length measurement and analysis module, the distance sensor 1 and the verification button are signal-connected with the length measurement and analysis module, the length measurement and analysis module is signal-connected with the verification cylinder, the pushing and restoring cylinder, the adjustment and traction control module, the cutting control module, and the abnormal alarm module.

[0010] In the above-mentioned CNC integrated steel bar straightening and cutting equipment, the timing of cutting the steel bar can be accurately controlled by monitoring the distance between the front end of the steel bar and the cutting mechanism, thereby effectively avoiding the cutting accuracy being affected by fluctuations in the conveying speed of the steel bar.

[0011] As a further improvement of the present application, the cutting length is set through the parameter setting module, and the length measurement and analysis module will control the telescopic adjustment of the testing cylinder according to the cutting length, so that when the distance between the front end of the steel bar and the cutting mechanism matches the cutting length, the follow-up length measuring plate will trigger the testing button, and when the testing button is triggered, it will send a signal to the length measurement and analysis module.

[0012] As a further improvement of the present application, the distance parameter is set through the parameter setting module according to the cutting length, so that when the distance between the front end of the steel bar and the cutting mechanism matches the cutting length, the distance between the distance sensor 1 and the follow-up length measuring plate will be equal to the distance parameter. During processing, the front end of the steel bar will push the follow-up length measuring plate after it hits the follow-up length measuring plate, so that the follow-up length measuring plate will approach the distance sensor 1 together. The distance sensor 1 can monitor the distance between it and the follow-up length measuring plate, and the monitored distance data will be transmitted to the length measurement analysis module in real time. When the test button is triggered and the distance between the distance sensor 1 and the follow-up length measuring plate reaches the distance parameter, the test button is triggered and the distance between the distance sensor 1 and the follow-up length measuring plate reaches the distance parameter. The length analysis module will send a signal to the cutting control module, so that the cutting control module controls the cutting mechanism to cut the steel bars. Then, the length measurement analysis module will control the push-return cylinder to push the follow-up length measurement plate, so that the follow-up length measurement plate moves toward the direction close to the cutting mechanism and resets. When the test button is triggered and the distance between the distance sensor 1 and the follow-up length measurement plate reaches the distance parameter, the length measurement analysis module will send a signal to the adjustment and traction control module, so that the adjustment and traction control module controls the straightening mechanism to stop straightening the steel bars, and controls the traction mechanism to stop traction and transportation of the steel bars. At the same time, the adjustment and traction control module will also start the abnormal alarm module to issue an alarm.

[0013] As a further improvement of the present application, the output end of the push-return cylinder is fixedly connected to an electromagnet, the side of the follow-up length measuring plate close to the electromagnet is fixedly connected to an iron block, and the length measurement analysis module is connected to the electromagnet signal, so that the cut steel bars can fall down better.

[0014] As another improvement of the present application, the equipment also includes a final measurement blanking mechanism, which includes a blanking box located below the double-inspection length measurement mechanism, the top of the blanking box is arranged to be open, and a rotation support plate is fixedly installed on the outer wall of the blanking box on the side away from the cutting mechanism, and a driving motor is fixedly installed on the rotation support plate, and the output end of the driving motor is fixedly connected to an auxiliary measurement material receiving assembly, which is composed of an end baffle, a side baffle, and a bottom guide plate.

[0015] As another improved supplement of the present application, the end baffle is fixedly connected to the output end of the driving motor, the side baffle and the bottom guide plate are fixedly connected to the end baffle, and the bottom guide plate is located at the bottom end of the side baffle, the top of the bottom guide plate is set to be an inclined surface, and the top of the bottom guide plate away from the side baffle is higher than the top of the bottom guide plate close to the side baffle.

[0016] As another improvement supplement to the present application, the auxiliary material receiving component is arranged in an inclined shape, and the end of the auxiliary material receiving component close to the cutting mechanism is higher than the end away from the cutting mechanism. The bottom end of the bottom guide plate is fixedly connected to a lifting support plate, and a lifting cylinder is fixedly installed on the lifting support plate. The output end of the lifting cylinder is fixedly connected to a distance sensor 2, and a fall measurement control module is also provided on the cutting CNC center.

[0017] As another improvement supplement to the present application, distance sensor 2 is arranged parallel to the bottom guide plate, the drop measurement control module is signal-connected to the driving motor, the lifting cylinder, and distance sensor 2, the parameter setting module and the length measurement and analysis module are signal-connected to the drop measurement control module, and the drop measurement control module is also signal-connected to the abnormal alarm module. The final measurement drop mechanism not only has the function of taking over the cut steel bars, but also has the function of further detecting the processing accuracy.

[0018] To summarize, the present application, through the setting of a double length measurement mechanism and a cutting CNC center, enables the integrated steel bar straightening and cutting equipment in the present application to accurately control the timing of cutting the steel bar by monitoring the distance between the front end of the steel bar and the cutting mechanism, thereby effectively avoiding the cutting accuracy being affected by fluctuations in the conveying speed of the steel bar, thereby effectively improving the processing quality, and having two different monitoring methods, which can be mutually verified. When a problem occurs in one of the monitoring methods, it can be discovered in time and shut down and alarm can be given, thereby further improving the processing quality; and through the setting of the final measurement blanking mechanism, the final measurement blanking mechanism not only has the function of taking over the cut steel bars, but also has the function of further detecting the processing accuracy, thereby further improving the processing quality.

DETAILED DESCRIPTION

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-5The invention shows a CNC steel bar straightening and cutting integrated equipment, including a straightening mechanism 001, a traction mechanism 002, a cutting mechanism 003, a double-checking and measuring length mechanism 004, and a CNC cutting center 005. The straightening mechanism 001 is used to straighten the steel bars, the traction mechanism 002 is used to traction and convey the steel bars, and the cutting mechanism 003 is used to cut the straightened steel bars. The straightening mechanism 001 and the cutting mechanism 003 are respectively located on both sides of the traction mechanism 002, and the steel bars cut by the cutting mechanism 003 will fall downward to the side of the cutting mechanism 003 away from the traction mechanism 002 (the straightening mechanism 001, the traction mechanism 002, and the cutting mechanism 003 are all mature existing technologies, and their specific structures are not described in detail here). The mechanism 004 comprises an L-shaped length measuring support frame 401, one end of which is fixedly connected to a length measuring support plate 402, on which a distance sensor 403, a support tube 404, a test cylinder 408 and a push-back cylinder 411 are fixedly mounted, and a connecting slide bar 405 is penetrated through the outer wall of the support tube 404 away from the end of the length measuring support plate 402, and the connecting slide bar 405 is slidably connected to the outer wall of the support tube 404, and both ends of the connecting slide bar 405 are respectively fixedly connected to a follow-up length measuring plate 406 and a stop block 407, the stop block 407 is located in the support tube 404 and abuts against the inner wall of the support tube 404, and the follow-up length measuring plate 406 is located between the cutting mechanism 003 and the distance sensor 403;

[0033] The output end of the test cylinder 408 is fixedly connected with a connecting plate 409, on which a test button 410 is fixedly installed. The test button 410 is a self-reset button. The adjustment and cutting CNC center 005 is provided with an adjustment and pulling control module, a cutting control module, a parameter setting module, a length measurement analysis module, and an abnormal alarm module;

[0034] The adjustment and traction control module is used to control the straightening mechanism 001 and the traction mechanism 002, the cutting control module is used to control the cutting mechanism 003, the parameter setting module is used to set the processing parameters, the parameter setting module is signal-connected with the adjustment and traction control module, the cutting control module and the length measurement and analysis module, the distance sensor 403 and the verification button 410 are signal-connected with the length measurement and analysis module, the length measurement and analysis module is signal-connected with the verification cylinder 408, the pushing cylinder 411, the adjustment and traction control module, the cutting control module and the abnormal alarm module.

[0035] The cutting length is set through the parameter setting module, and the length measurement and analysis module will control the telescopic adjustment of the test cylinder 408 according to the cutting length, so that when the distance between the front end of the steel bar and the cutting mechanism 003 (more accurately, the distance between the front end of the steel bar and the cutting point) matches the cutting length (that is, when the steel bar is to be cut), the follow-up length measurement plate 406 will just trigger the test button 410. When the test button 410 is triggered, a signal will be sent to the length measurement and analysis module. After the test cylinder 408 is telescopically adjusted, the position of the test button 410 is its origin position. , the distance parameter is set through the parameter setting module according to the cutting length, so that when the distance between the front end of the steel bar and the cutting mechanism 003 matches the cutting length (that is, when the steel bar is cut), the distance between the distance sensor 403 and the follow-up length measuring plate 406 will be equal to the distance parameter. During processing, the front end of the steel bar will push the follow-up length measuring plate 406 after it hits the follow-up length measuring plate 406, so that the follow-up length measuring plate 406 will move closer to the distance sensor 403. The distance sensor 403 can monitor the distance between it and the follow-up length measuring plate 406, and the monitored The distance data will be transmitted to the length measurement analysis module in real time. When the test button 410 is triggered and the distance between the distance sensor 403 and the follow-up length measurement plate 406 reaches the distance parameter, the length measurement analysis module will send a signal to the cutting control module to control the cutting mechanism 003 to cut the steel bar. Then, the length measurement analysis module will control the push-back cylinder 411 to push the follow-up length measurement plate 406 to move and reset in the direction close to the cutting mechanism 003 (the push-back cylinder 411 pushes the follow-up length measurement plate 406 to make it move and reset). After the follow-up length measuring plate 406 is reset, the length measuring analysis module will also control the push-reset cylinder 411 to reset itself). When the test button 410 is triggered and the distance between the distance sensor 403 and the follow-up length measuring plate 406 reaches the distance parameter, the length measuring analysis module will send a signal to the adjustment and traction control module to control the straightening mechanism 001 to stop straightening the steel bars, and control the traction mechanism 002 to stop traction and transportation of the steel bars. At the same time, the adjustment and traction control module will also start the abnormal alarm module to alarm;

[0036] Therefore, under the joint action of the double-verification and measuring length mechanism 004 and the cutting and adjusting numerical control center 005, the timing of cutting the steel bar can be accurately controlled by monitoring the distance between the front end of the steel bar and the cutting mechanism 003, and the double-verification and measuring length mechanism 004 has two different monitoring methods, one is through the distance sensor 403, and the other is through the verification and measuring button 410, and the distance sensor 403 indirectly monitors the distance between it and the front end of the steel bar by monitoring the distance between it and the follow-up length measuring plate 406, thereby realizing the monitoring of the distance between the front end of the steel bar and the cutting mechanism 003. Compared with directly monitoring the distance between the distance sensor 403 and the front end of the steel bar, it is not easy to affect the monitoring accuracy due to the thin steel bar or the displacement of the steel bar, thereby improving the monitoring accuracy. In addition, the two monitoring methods can be verified with each other. When a problem occurs in one of the monitoring methods (that is, when the verification and measuring button 410 is triggered and the distance between the distance sensor 403 and the follow-up length measuring plate 406 reaches the distance parameter, these two situations do not occur at the same time), it can be discovered and alarmed in time, prompting relevant technical personnel to carry out corresponding inspections and maintenance in time;

[0037] Therefore, through the setting of the double length measurement mechanism 004 and the cutting CNC center 005, the integrated steel bar straightening and cutting equipment in the present application can accurately control the timing of cutting the steel bar by monitoring the distance between the front end of the steel bar and the cutting mechanism 003, thereby effectively avoiding the cutting accuracy being affected by fluctuations in the conveying speed of the steel bar, thereby effectively improving the processing quality, and having two different monitoring methods, which can be verified with each other. When a problem occurs in one of the monitoring methods, it can be discovered in time and shut down and alarm can be given, thereby further improving the processing quality.

[0038] See also Figure 2-5The output end of the push-return cylinder 411 is fixedly connected to an electromagnet 412, and an iron block 413 is fixedly connected to the side of the follow-up length measuring plate 406 close to the electromagnet 412. The length measuring analysis module is connected to the electromagnet 412 signal. When the length measuring analysis module sends a signal to the cutting control module (that is, before the length measuring analysis module controls the push-return cylinder 411 to push the follow-up length measuring plate 406 to reset), the length measuring analysis module will also start the electromagnet 412, and control the test cylinder 408 and the push-return cylinder 411 to pull the connecting plate 409 and the electromagnet 412 to move a certain distance away from the cutting mechanism 003. In this process, Under the action of the magnetic attraction between the magnet 412 and the iron block 413, the follow-up length measuring plate 406 will move together with the connecting plate 409, the electromagnet 412, etc. in the direction away from the cutting mechanism 003, so that the cut steel bars can fall down better, and in this process, the testing button 410 will always be in a triggered state, thereby preventing the testing button 410 from being triggered by mistake, and then the length measurement and analysis module will turn off the electromagnet 412, and control the push-return cylinder 411 to push the follow-up length measuring plate 406 to reset. At the same time, the length measurement and analysis module will also control the testing cylinder 408 to push the connecting plate 409 to reset the testing button 410 to its original position.

[0039] The second implementation method:

[0040] Figure 6-9The invention shows a CNC steel bar straightening and cutting integrated equipment, which is different from the first embodiment in that it also includes a final measurement blanking mechanism 006, which includes a blanking box 601 located below the double-verification and length measurement mechanism 004, and the top of the blanking box 601 is set to be open, and a rotation support plate 602 is fixedly installed on the outer wall of the blanking box 601 away from the cutting mechanism 003, and a driving motor 603 is fixedly installed on the rotation support plate 602, and the output end of the driving motor 603 is fixedly connected to an auxiliary measurement material receiving assembly, which is composed of an end baffle 604, a side baffle 605, and a bottom guide plate 606, and the end baffle 604 is fixedly connected to the output end of the driving motor 603, and the side baffle 605 and the bottom guide plate 606 are fixedly connected to the end baffle 604, and the bottom guide plate 606 is located at the bottom end of the side baffle 605, and the top of the bottom guide plate 606 is set to The bottom guide plate 606 is in the shape of an inclined surface, and the top of the end of the bottom guide plate 606 away from the side baffle plate 605 is higher than the top of the end close to the side baffle plate 605. The auxiliary measuring material receiving component is arranged in an inclined shape, and the end of the auxiliary measuring material receiving component close to the cutting mechanism 003 is higher than the end away from the cutting mechanism 003. The bottom end of the bottom guide plate 606 is fixedly connected with a lifting support plate 607, and a lifting cylinder 608 is fixedly installed on the lifting support plate 607. The output end of the lifting cylinder 608 is fixedly connected with a distance sensor 2 609. A drop measurement control module is also arranged on the cutting CNC center 005. The distance sensor 2 609 is arranged parallel to the bottom guide plate 606. The drop measurement control module is signal-connected with the driving motor 603, the lifting cylinder 608, and the distance sensor 2 609. The parameter setting module and the length measurement analysis module are signal-connected with the drop measurement control module. The drop measurement control module is also signal-connected with the abnormal alarm module.

[0041] The cut steel bar will fall onto the auxiliary measuring material connection component, and because the auxiliary measuring material connection component is set to an inclined shape, the steel bar will slide, causing one end of the steel bar to abut against the end baffle 604. In addition, because the top of the side baffle 605 is set to an inclined surface, the steel bar will also roll until it is in contact with the side baffle 605. The length measurement and analysis module will send a signal to the cutting control module, so that the cutting control module controls the cutting mechanism 003 to cut the steel bar, and then sends a signal to the falling measurement control module. After receiving the signal, the falling measurement control module will first control the lifting cylinder 608 to drive the distance sensor 2 609 to move upward a certain distance, causing the distance sensor 609 to move upward a certain distance. The distance sensor 609 moves to a height that matches the steel bars on the auxiliary material-jointing assembly (the initial position of the distance sensor 609 is lower than the bottom guide plate 606 to prevent the distance sensor 609 from being hit by the steel bars). Then, the drop detection control module starts the distance sensor 609 to enable the distance sensor 609 to detect the distance between it and the end of the steel bar away from the end baffle 604, and the distance data detected by the distance sensor 609 is transmitted to the drop detection control module, which analyzes the distance data detected by the distance sensor 609 according to the cutting length to further determine whether there is a problem with the processing accuracy.

[0042] Assume that the cutting length is L1, the distance between the distance sensor 609 and the end baffle 604 is L2 (L2 is known data), and the distance data detected by the distance sensor 609 is L3. If the difference between L3, L2 and L1 matches, it means that there is no problem with the processing accuracy. On the contrary, if the difference between L3, L2 and L1 does not match, it means that there is a problem with the processing accuracy (the reasons for this situation include problems with the cutting accuracy, problems with the straightening accuracy, etc. When there is a problem with the cutting accuracy, the length of the cut steel bar will not be equal to the cutting length, so it will cause L3 to not match the difference between L2 and L1. When there is a problem with the straightening accuracy, the steel bar will not be completely straightened and will still be bent, which will cause the steel bar to be unable to completely fit the side baffle 605, and will also cause the end of the steel bar away from the end baffle 604 to be unable to accurately align with the distance sensor 606). 09, which will also cause the difference between L3 and L2 and L1 to not match). When the judgment result is that there is no problem with the processing accuracy, the drop measurement control module will turn off the distance sensor 609 and control the lifting cylinder 608 to drive the distance sensor 609 to move downward and reset. At the same time, the drop measurement control module will also control the driving motor 603 to drive the auxiliary measurement material receiving assembly to rotate a certain angle, so that the steel bar can be separated from the auxiliary measurement material receiving assembly and fall into the drop box 601. Then, the drop measurement control module will control the driving motor 603 to drive the auxiliary measurement material receiving assembly to rotate and reset. When the judgment result is that there is a problem with the processing accuracy, the drop measurement control module will control the abnormal alarm module to issue an alarm. Therefore, through the setting of the final measurement drop mechanism 006, the final measurement drop mechanism 006 not only has the function of receiving the cut steel bars, but also has the function of further detecting the processing accuracy, thereby further improving the processing quality.

[0043] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. 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 scope of protection of the present invention.

The CNC steel bar straightening and cutting integrated equipment according to claim 2 is characterized in that: The distance parameter is set through the parameter setting module according to the cutting length, so that when the distance between the front end of the steel bar and the cutting mechanism (003) matches the cutting length, the distance between the distance sensor 1 (403) and the follow-up length measuring plate (406) will be equal to the distance parameter. During processing, the front end of the steel bar will push the follow-up length measuring plate (406) after it hits the follow-up length measuring plate (406), so that the follow-up length measuring plate (406) will approach the distance sensor 1 (403). The distance sensor 1 (403) can monitor the distance between it and the follow-up length measuring plate (406), and the monitored distance data will be transmitted to the length measurement analysis module in real time. When the test button (410) is triggered and the distance between the distance sensor 1 (403) and the follow-up length measuring plate (406) reaches the distance parameter, the length measurement is performed. The analysis module will send a signal to the cutting control module, so that the cutting control module controls the cutting mechanism (003) to cut the steel bar. Then, the length measurement analysis module will control the push cylinder (411) to push the follow-up length measurement plate (406), so that the follow-up length measurement plate (406) moves in a direction close to the cutting mechanism (003) to reset. When the test button (410) is triggered and the distance between the distance sensor 1 (403) and the follow-up length measurement plate (406) reaches the distance parameter, the length measurement analysis module will send a signal to the adjustment and traction control module, so that the adjustment and traction control module controls the straightening mechanism (001) to stop straightening the steel bar, and controls the traction mechanism (002) to stop traction and transportation of the steel bar. At the same time, the adjustment and traction control module will also start the abnormal alarm module to issue an alarm.
