Description

Technical Field

[0001] The invention relates to the field of material hardness detection, and in particular to an online automatic detection system for the full width of a large steel plate hardness based on a gate-type Brinell hardness tester. Background Art

[0002] Large steel plates (8500×2000×15) need to be hardness tested after continuous pressure quenching. Due to the large width of the steel plate, there are many factors affecting the quenching hardness, including the heating system, cooling system and pressure quenching machine tools. Problems in one or several links in the production process may lead to insufficient quenching hardness of the steel plate. Therefore, it is necessary to conduct timely and effective evaluation of the hardness of the steel plate after quenching to prevent batch quality problems. The current hardness test method is offline detection, that is, after the furnace is opened, two diagonal flame cutting samples are taken on the two steel plates that have been quenched, and then sent to the inspection station for hardness testing. The disadvantage of this method is that the sampling and detection cycle is long and the sampling points are too few. It is impossible to evaluate the quenching hardness of the steel plate in real time and comprehensively. When the production process is abnormal, it is easy to cause batch quality problems. Summary of the invention

[0003] The purpose of the present invention is to provide a large-scale steel plate full-width online automatic detection system for hardness based on a portal Brinell hardness tester, comprising an entrance counter, a blocking device I, a correction device group I, a safety sensor, a correction device group II, a water removal device, a digital display Gate Brinell hardness tester, a control cabinet, a correction device group III, a detection table steel plate in-place sensor, a feeding table, a blocking device II, a steel plate Y-axis positioning monitoring device, a host computer, and a detection table.

[0004] A plurality of rollers are installed on the unloading platform and the testing platform, and the rollers are driven by motors to transmit the steel plates in a chain linkage manner.

[0005] The conveying end of the unloading platform is connected with the conveying end of the testing platform, and a digital display Mennell Brinell hardness tester is installed between the two.

[0006] An end of the unloading platform away from the detection platform is provided with an entrance counter, a blocking device I, and a correction device group I in sequence.

[0007] The end of the unloading platform close to the detection platform is provided with a blocking device II and a water removal device in sequence.

[0011] A host computer is arranged on one side of the detection platform.

[0012] When the automatic detection system is used to test the hardness of the steel plate, the blocking device is first sunk and raised, the entrance counter starts counting, the steel plate is conveyed to the unloading table via a roller, the steel plate is corrected by the correction device group I and the correction device group II, the blocking device is then sunk, the steel plate is conveyed to the detection table via a roller, and the water removal device removes the accumulated water on the surface of the steel plate. When the steel plate in place sensor on the detection table detects that the steel plate is in place, the roller conveyance is stopped, the steel plate is corrected by the correction device group III, and then it is conveyed via a roller to ensure that the steel plate enters the hardness detection area. The Y-axis coordinate of the steel plate is detected by the steel plate Y-axis positioning monitoring device, and the detection position of the steel plate is located by the host computer. The hardness measurement function mode is selected by the host computer, and the hardness of the detection position of the steel plate is tested by the digital display Mennell Brinell hardness tester, and the test data is transmitted to the host computer. After the test is completed, the blocking device is raised, and the steel plate is conveyed to the unloading table through the roller, waiting for the user to unload the material. When the safety sensor detects that there is no material on the unloading table, the next steel plate can be unloaded.

[0013] Furthermore, the digital display Mannell Brinell hardness tester includes a gantry, a Brinell hardness loading and unloading component, a clamping device, an automatic drying device, an automatic grinding device, an indenter, an indentation measuring device, and a liftable workbench.

[0014] A liftable workbench is provided at the bottom of the gantry.

[0015] The gantry is provided with a clamping device, an automatic drying device, an automatic grinding device, an indentation head, and an indentation measuring device.

[0016] The top of the gantry is provided with a Brinell hardness loading and unloading component, and the Brinell hardness loading and unloading component is connected with the pressure head.

[0017] When the digital display Mennell Brinell hardness tester performs hardness testing on the detection position of the steel plate, the lifting table rises to the specified position, the steel plate is clamped by the clamping device, and the upper computer controls the digital display Mennell Brinell hardness tester to move to the detection position of the steel plate. The automatic drying device first dries the detection position of the steel plate, and then the automatic grinding device is used to grind the detection position of the steel plate. After grinding, the Brinell hardness loading and unloading component drives the indenter to press the polished detection position to press out the Brinell hardness detection indentation, and then the indentation measurement device identifies and calculates the Brinell hardness detection indentation, and uploads the calculated signal to the upper computer.

[0018] Furthermore, the indentation measuring device takes a picture of the indentation through a camera, and then identifies and calculates the Brinell hardness value.

[0019] Furthermore, the automatic drying device, the automatic polishing device, the indenter, and the indentation measuring device move along the X direction on the gantry.

[0020] Furthermore, the automatic detection system is used to perform real-time full-plate width online detection on the steel plates discharged from the pressure quenching production line.

[0021] Furthermore, the detection platform is provided with a control cabinet on the other side of the host computer.

[0022] The technical effect of the present invention is unquestionable. The present invention is integrated with the steel plate pressure quenching line, which greatly improves the degree of automation of the hardness detection of the steel plate in the quenching line and improves the production efficiency. It can cover the Brinell hardness detection of any part of the steel plate and adapt to the online automatic detection of the Brinell hardness of a certain plane warped steel plate, which solves the problem of multi-point hardness detection of the entire plate width of large steel plates. It can timely, comprehensively and accurately evaluate whether the hardness of the steel plate quenching meets the process requirements, thereby avoiding the occurrence of batch quality accidents caused by insufficient hardness of the steel plate due to untimely hardness detection and insufficient detection range under abnormal process conditions.

[0081] See also Figure 1 to Figure 2 , a large-scale steel plate full-width online automatic detection system for hardness based on a portal Brinell hardness tester, the main technical content is shown in Example 13, further, the steps of using the automatic detection system to perform steel plate hardness detection are as follows:

[0082] 1) After the steel plate is pressure quenched, the material is discharged, the blocking device I2 sinks, the counting sensor starts counting, and the blocking device II12 rises;

[0083] 2) The steel plate is transferred to the unloading platform 11 via the transfer roller and stops; the deviation correction device I3 and the deviation correction device II5 correct the steel plate to facilitate accurate transfer to the detection platform 15 in the next step.

[0084] 3) The blocking device II12 sinks, and the steel plate is transmitted to the testing platform through the transmission roller. At the same time, the water removal device 6 removes the accumulated water on the surface of the steel plate. After the steel plate in place sensor 10 of the testing platform detects that the steel plate is in place, the steel plate stops, and the correction device corrects the steel plate again to ensure that the steel plate accurately enters the hardness detection position.

[0085] 4) The transmission roller conveys the steel plate to the detection area of ​​the digital display portal Brinell hardness tester 7. The point laser sensor on the steel plate Y-axis positioning monitoring device 13 detects that the steel plate is in place. The floating bracket on the steel plate Y-axis positioning monitoring device sinks under the push of the cylinder and contacts the surface of the steel plate. The rubber wheel installed on the bracket drives the encoder to rotate, detects the Y-axis coordinate of the steel plate, and locates the detection position of the steel plate through the program control system;

[0086] 5) When the steel plate is transferred to the set hardness test position, the steel plate stops, the lifting table 22 of the digital display door-type Brinell hardness tester 7 rises to the specified position, and the clamping device 17 descends to press the steel plate;

[0087] 6) When the detection component on the digital display door-type Brinell hardness tester 7 moves to the set hardness detection point through the program control system, the drying device 18 installed next to the grinding device 19 is started to dry the water marks on the surface of the steel plate at the detection point, and the automatic grinding device descends to the grinding point to grind the detection plane. After grinding, the Brinell hardness loading and unloading component 16 drives the pressure head 20 to apply pressure to the polished detection plane according to the set pressure, pressing out the Brinell hardness detection indentation, and then the indentation measurement device 21 identifies and calculates the indentation, and uploads the signal to the host computer, calculates the Brinell hardness value and stores it for display. After the detection is completed, the detection component moves to the next position for detection.

[0088] 7) After the entire hardness test is completed according to the set requirements, the blocking device I2 rises, and the transmission system transfers the steel plate to the unloading platform, waiting for the workers to unload the steel plate. The workers use the crane to lift the steel plate off the unloading platform. When the safety sensor detects that there is no material on the unloading platform, the next steel plate can be unloaded.
