Description

Technical Field

[0002] Steel structure connection plates are usually set between two steel structure members or components, with weld connection, bolt connection or rivet connection. Since the middle of the last century, the use of high-strength bolt connection has developed rapidly. Therefore, it is necessary to open holes in the steel structure connection plates to connect the steel structure members or components with high-strength bolts.

[0003] At present, steel structure connection plates are generally made of steel plates with a thickness of 4-30 mm. Generally, when connecting steel structures, the thickness of the steel structure connection plates needs to be 1.5 times that of the parent material (steel structure member). The processing method of steel structure connection plates is mainly to cut a small plate on the steel plate according to the size and shape of the required steel structure connection plate, and then use a drilling machine to drill holes on the small plate to obtain the steel structure connection plate. However, the more structural connection plate needs to connect two steel structure members, so there are four holes on both ends. The drilling machine is used for drilling holes, and the processing efficiency is low. The steel structure connection plate is used to connect the steel members between the two steel structure members, and its strength requirements are relatively high. The common steel plate is hot-rolled steel plate. Although its strength is improved by hot rolling, it still has certain defects.

[0031] See attached Figure 1 and attached Figure 2The embodiment of the present application provides a steel structure connection plate stamping system, including a heating furnace 1, a dephosphorization machine 2, a hot rolling machine 3, a punching machine 4 and a cutting machine 5 which are arranged in sequence along the production line. A displacement mechanism 10 is arranged at the bottom of the punching machine 4, and the displacement mechanism 10 is transmission-connected to the punching machine 4, so that the displacement mechanism 10 can drive the punching machine 4 to move along the production line. When the punching machine 4 is used to punch the hot-rolled steel plate, the displacement speed of the punching machine 4 is the same as the translation speed of the steel plate in the horizontal direction. This avoids the problem of uneven surface of the hot-rolled steel plate caused by stopping the hot rolling process or stopping the steel plate during the punching process, and at the same time avoids the formation of a displacement difference between the steel plate and the punching machine 4, which affects the punching of the steel plate and the punching machine 4. In addition, the punching process is after the steel plate is hot-rolled, and the steel plate still has a certain recrystallization temperature. At this time, the tonnage required for punching is small.

[0032] In this embodiment, the displacement mechanism 10 drives the punching machine 4 to move following the steel plate. Due to the arrangement of the displacement mechanism 10, the steel plate does not need to be stopped each time the punching machine 4 performs a punching operation. In this way, the surface of the steel plate hot-rolled by the hot rolling mill 3 is smoother. If the steel plate stops for a period of time, the action of the hot rolling mill 3 will cause the surface of the steel plate to be uneven during the rolling process, which will cause rapid defects in the processed steel structure connecting plate. The arrangement of the displacement mechanism 10 can make the punching operation consistent with the displacement of the steel plate, avoid the displacement difference between the steel plate and the punch of the punch 4, effectively improve the quality of the punching holes, and prevent the steel plate from causing damage to the punch of the punch 4 during punching.

[0033] In this embodiment, the outlet of the heating furnace 1 is connected to the inlet of the dephosphorization machine 2, the outlet of the dephosphorization machine 2 is connected to the inlet of the hot rolling mill 3, the outlet of the hot rolling mill 3 is connected to the inlet of the punching machine 4, the outlet of the punching machine 4 is connected to the inlet of the cutting machine 5. Of course, a convection cooler and a stacker are provided at the outlet of the cutting machine 5. The cutting machine 5 cuts the steel plate after hot punching according to the shape of the required steel structure connecting plate, and cools it in the convection cooler after cutting. After the cooling treatment is completed, it is stacked by the stacker. The steel structure connecting plate after cooling can be used. Of course, in order to ensure the quality of the steel structure connecting plate, it is necessary to perform quality inspection on the steel structure connecting plate. The quality inspection includes but is not limited to load action detection, damage measurement, strength detection, stability verification, stiffness detection, dynamic performance detection, fatigue and fracture detection, bearing capacity test, hole diameter and position detection; of course, in order to avoid the burrs generated by the steel structure connecting plate during the cutting process from affecting the steel structure, deburring can be performed.

[0034] In this embodiment, the heating furnace 1 is provided with a first-stage heater, a second-stage heater and a third-stage heater, and the first-stage heater, the second-stage heater and the third-stage heater are all electromagnetic heaters. A heating channel runs through the first-stage heater, the second-stage heater and the third-stage heater. A support seat is provided in the heating channel, and the support seat is provided along the extension direction of the heating channel. A ceramic roller is provided on the support seat, and the ceramic roller is rotatably connected to the support seat, and the ceramic roller supports the steel plate at the same time; a supporting groove is provided on the upper side of the support seat, and the ceramic roller is provided in the supporting groove, and a connecting hole is provided on the side wall on the opposite side of the supporting groove, and connecting ends are provided at both ends of the ceramic roller, respectively, and the connecting ends It extends into the connecting hole, and a roller is rotatably arranged on the bottom wall of the connecting hole, and the lower side wall surface of the connecting end is in contact with the roller; of course, the connecting end is cylindrical, and the porcelain roller can rotate when the steel plate moves; the material of the support seat and the porcelain roller are both ceramic, which cannot be heated under the electromagnetic action, so that the electromagnetic action can heat the steel plate; the first stage heater performs the first electromagnetic heating on the steel plate, and the heating temperature is 150-200℃; the second stage heater performs the second electromagnetic heating on the steel plate, and the heating temperature is 350-400℃; the third stage heater performs the third electromagnetic heating on the steel plate, and the heating temperature is 550-600℃.

[0035] In this embodiment, the dephosphorization machine 2 removes the iron oxide scale on the surface of the steel plate, including a bracket, a motor, a reducer, a lifting device and a brush roller. The brush roller is arranged on the lifting device, and the brush body on the roller contacts the moving high-temperature steel plate to remove the iron oxide scale on the high-temperature steel plate before rolling; of course, in order to better remove the oxide scale on both sides of the high-temperature steel plate, the brush roller is respectively arranged on the upper and lower sides of the high-temperature steel plate. The dephosphorization machine 2 can effectively remove the oxide scale on the surface of the steel plate, and can prevent the oxide scale from interfering with the hot rolling of the steel plate.

[0036] In this embodiment, a guide roller group 6 is arranged between the hot rolling mill 3 and the punching machine 4, and a laser marking machine 7 is arranged above the guide roller group 6. The laser marking machine 7 is used to mark punching marks at the punching positions.

[0037] In this embodiment, the laser engraving machine 7 is arranged along the width direction of the steel plate. The laser engraving machine 7 is arranged above the guide roller group 6. The output end of the laser engraving machine 7 is perpendicular to the upper surface of the rolled steel plate, and a "cross-shaped" punching mark is laser-engraved on the steel plate. The center of the "cross-shaped" punching mark corresponds to the center of the hole. In this embodiment, four bolt holes distributed in different directions need to be processed on both ends of the steel structure connecting plate. Therefore, Figure 1As shown, when the steel plate continues to move to the right after being rolled by the hot rolling mill 3, the laser engraving machine 7 laser engraves a "cross-shaped" punching mark on the steel plate along the width direction of the steel plate (perpendicular to the length direction of the steel plate). For a steel structure connecting plate, the laser engraving machine 7 laser engraves two or four "cross-shaped" punching marks at a time, and after the steel plate continues to move and accumulates a certain amount of displacement, it continues to laser engrave other "cross-shaped" punching marks.

[0038] In this embodiment, an infrared thermal imaging scanner 8 is also arranged between the laser engraving machine 7 and the punching machine 4. The infrared thermal imaging scanner 8 is provided with a distance measuring controller and a speed measuring controller. The infrared thermal imaging scanner 8 and the displacement mechanism 10 are both electrically connected to the speed measuring controller, and the infrared thermal imaging scanner 8 and the laser engraving machine 7 are both electrically connected to the distance measuring controller.

[0039] In this embodiment, the speed measuring controller and the distance measuring controller are both provided with an image processor, an information processor and a computer. The image processor is used to implement target capture of the "cross-shaped" punching mark of the image output by the infrared thermal imaging scanner 8, and the information processor is used to upload the target information of the "cross-shaped" punching mark captured by the image processor to the computer. The computer calculates the speed value of the "cross-shaped" punching mark and the displacement in a certain period of time according to the target information, and then converts the speed value into a speed control signal to control the operation of the reciprocating telescopic rod, and converts the displacement value into a laser engraving control signal to control the laser engraving machine 7 to perform engraving; the infrared thermal imaging scanner 8 identifies the "cross-shaped" punching mark engraved on the surface of the steel plate by performing thermal imaging photography on the surface of the steel plate. When the displacement change of the "cross-shaped" punching mark is respectively identified after two photography intervals, the displacement speed of the rolled steel plate can be obtained, and then the punching machine 4 is driven by the displacement mechanism 10 to move at the same speed as the steel plate to perform punching and hole-opening operations; of course, the infrared thermal imaging scanner 8 performs thermal imaging photography on the steel plate to identify the "cross-shaped" punching mark. The displacement path of the "cross-shaped" punching mark, within a certain period of time, the "cross-shaped" punching mark will accumulate a certain amount of displacement. When the displacement reaches the specified position of the hole spacing, the laser continues to engrave a new "cross-shaped" punching mark. The new "cross-shaped" punching mark is photographed and recognized as the steel plate moves, and can continue to be used to measure the speed and displacement values ​​of the steel plate; of course, in order to avoid the "cross-shaped" punching mark following the displacement of the steel plate is not a linear displacement, so that the previously processed "cross-shaped" punching mark and the newly engraved "cross" by the laser engraving machine 7 There are differences between the "cross-shaped" punching marks, the laser marker 7 is provided with an adjustment mechanism for adjusting the position of the laser marker 7 in the width direction of the steel plate. Of course, the laser marker 7 is also provided with a path controller, and the path controller is electrically connected to the adjustment mechanism; the path controller receives multiple pictures output from the thermal imaging scanner 8, and captures the "cross-shaped" punching mark, generates the path of the "cross-shaped" punching mark, calculates the difference between the first and last ends of the path in the width direction of the steel plate, and adjusts the position of the laser marker 7 through the difference control adjustment mechanism.

[0040] In this embodiment, a punching positioning visual mechanism 9 for locating the punching position is provided on the punching machine 4 , and the punching positioning visual mechanism 9 is electrically connected to the punching machine 4 and the displacement mechanism 10 , respectively.

[0041] In this embodiment, the punching positioning visual mechanism 9 includes at least two positioning industrial cameras, which are respectively fixed on both sides of the punching machine 4, and the shooting ends of the two positioning industrial cameras are both facing the punching work area of ​​the punching machine 4.

[0042] In this embodiment, two positioning industrial cameras are respectively arranged at the entrance and exit of the punching machine 4, or in other words, "upstream" and "downstream" along the length direction of the steel plate. The shooting ends of the two positioning industrial cameras are both facing the bottom of the punching machine 4 to photograph the steel plate, obtain images and identify the position of the "cross-shaped" punching mark. The two positioning industrial cameras cooperate with each other, and based on the principle of "binocular positioning", the position relationship between the "cross-shaped" punching mark and the punching machine 4 can be obtained more accurately, and then the bolt holes of the steel structure connecting plate can be punched and processed by the punching machine 4; of course, when the "cross-shaped" punching mark obtained by the two positioning industrial cameras does not correspond to the position of the die of the punching machine 4, the position of the punching machine 4 relative to the "cross-shaped" punching mark is adjusted by the displacement mechanism 10, and then the punching operation is performed.

[0043] In this embodiment, the guide roller group 6 includes a support guide groove 61 and a plurality of guide rollers 62 , and the guide rollers 62 are rotatably disposed in the support guide groove 61 .

[0044] In this embodiment, the displacement mechanism 10 includes a guide rail 101 and a reciprocating pusher 102 . The bottom of the punching machine 4 is slidably connected to the guide rail 101 , and the output end of the reciprocating pusher 102 is drivingly connected to the punching machine 4 .

[0045] In this embodiment, the guide rail 101 is fixedly installed on the ground, and one end of the reciprocating pusher 102 is fixed on the ground. Of course, the ground here is stationary relative to the heating furnace 1, the dephosphorization machine 2 or the hot rolling mill 3, and is used to provide support or pulling force to the reciprocating pusher 102 to ensure that the reciprocating pusher 102 stably drives the reciprocating left and right movement displacement of the punching machine 4.

[0046] In this embodiment, the reciprocating pusher 102 is a hydraulic telescopic rod.

[0047] In this embodiment, a guide wheel 11 is disposed between the bottom of the punching machine 4 and the guide rail 101 . The guide wheel 11 is rotatably disposed at the bottom of the punching machine 4 , and the guide wheel 11 is rollingly connected to the guide rail 101 .

[0048] In this embodiment, the punching machine 4 is provided with a male die and a female die, the male die is arranged above the female die, in order to better ensure the displacement of the punching machine 4 relative to the steel plate, the female die is arranged on a lifting seat, and the lifting seat is controlled by a lifter to lift and lower, so that when the punching machine 4 and the steel plate are displaced at the same speed, or when punching and opening holes, the top of the female die can contact the steel plate, and when the punching machine 4 and the steel plate are at different speeds, the lifter drives the female die downward so that the upper end of the female die does not contact the steel plate, until the displacement of the punching machine 4 and the steel plate is adjusted to be at the same speed, and then the female die is driven upward to contact the steel plate; the male die moves downward from the top of the steel plate, and cooperates with the female die on the steel plate The upper punching forms an opening, and the waste obtained by punching does not fall off from the die; of course, a waste discharge port is set on the bottom side of the punching machine 4, and the lower end of each die is connected to the waste discharge port. The waste obtained by punching falls into the waste discharge port from the lower end of the die, and then is discharged from the punching machine 4 from the waste discharge port; in order to realize a multi-hole punching operation, the punching machine 4 is equipped with multiple groups of dies and punches, and the hot rolling mill 3 rolls the steel plate at a speed of 3-5m / min. After the punching machine 4 punches once, it has sufficient time to reset under the action of the displacement mechanism 10, and then perform the second punching operation.

[0049] In this embodiment, after the steel plate is rolled by the hot rolling mill 3, the steel plate is still in a high-temperature state and has a weaker anti-stamping effect compared to the steel plate at room temperature. Therefore, the punching machine 4 performs hot punching on the steel plate without using a punching machine 4 with a higher tonnage than that required for punching steel plates at room temperature. The tonnage here refers to the size of the punching required for punching. Therefore, the punching machine 4 used in this embodiment can use a punching machine 4 with a lower tonnage to achieve the punching and opening operation of the steel structure connecting plate.

[0050] In this embodiment, the cutting machine 5 is any one of a flame cutting machine, a plasma cutting machine and a laser cutting machine; in this embodiment, the cutting machine 5 is preferably a flame cutting machine.

[0054] The number of different steel structure connection plates required is determined according to the market demand for steel structure connection plates;

[0055] 2. The laser engraving machine 7 laser engraves a "cross-shaped" punching mark on the steel plate based on the blueprint and the distance value obtained by the distance measuring controller; when the "cross-shaped" punching mark in the picture taken by the infrared thermal imaging scanner 8 is analyzed, the position of the laser engraving machine 7 in the width direction of the steel plate is adjusted, and a new "cross-shaped" punching mark is laser engraved;

[0056] 3. The displacement mechanism 10 drives the punching machine 4 to move in the same direction at the same speed according to the speed value obtained by the speed measuring controller;

[0057] 4. The punching positioning visual mechanism 9 takes a picture of the "cross-shaped" punching mark under the punch of the impact machine and positions it;

[0058] When the punching positioning visual mechanism 9 recognizes that the "cross-shaped" punching mark and the punching machine 4's punch die cannot be positioned, the information that the position cannot be positioned is transmitted to the displacement mechanism 10, and the displacement mechanism 10 appropriately speeds up or slows down, and adjusts until the "cross-shaped" punching mark photographed by the punching positioning visual mechanism 9 and the punching machine 4's die are accurately positioned, the displacement mechanism 10 continues to drive the punching machine 4 to move at an instant speed according to the speed value given by the speed measuring controller, and at the same time, the punching machine 4 drives the punch die to cooperate with the die to perform kinematic punching and opening of holes on the steel plate;

[0059] 5. After the punching is completed, the displacement mechanism 10 drives the punching machine 4 to reset to the left, and then drives the punching machine 4 to move to the right according to the speed value of the speed measuring controller, until the punching positioning visual mechanism 9 takes a picture of the "cross-shaped" punching mark under the punch of the impact machine, and after positioning, the punching machine 4 punches the steel plate again;

[0060] 6. The cutting machine 5 cuts the hot punched steel plates according to the shapes of the steel structure connecting plates in the blueprint to obtain steel structure connecting plates with various punching requirements and sizes.
