Description

Technical Field

[0001] The present invention relates to a feeding device for the milling slope groove of steel plates and a feeding control method, belonging to the technical field of feeding devices for the peripheral slope grooves of steel plates used for circular tube forming. Background Art

[0002] A steel plate groove is an operation of grooving the part to be welded before welding in order to ensure the welding quality during the welding manufacturing process. The existence of the groove can enable the welding electrode or welding wire to better enter the weld, increase the penetration depth and width of the weld, and improve the strength and tightness of the welded joint.

[0003] Steel plates have many uses, including dock steel plates, steel plates for circular tube forming, etc. Generally, only one welding edge of the steel plate needs to be grooved, while the steel plate used for circular tube forming needs to be grooved on at least one set of opposite edges, and the parallelism of the groove forming of the opposite edges needs to be ensured.

[0004] In traditional groove operations, a groove device with a baffle is used in cooperation with a steel plate support table. The steel plate is suspended onto the steel plate support table and then pushed to abut against the baffle of the groove device. Then, after the baffle descends, the groove device is translated to the processing station, and the milling operation is realized through the linear movement of the main shaft.

[0005] It has many defects. Firstly, for the steel plate support table, the traditional steel plate support table uses balls distributed in a matrix to support the steel plate. Such a design results in a small pushing force. However, after the steel plate is pushed to abut and be positioned against the baffle and then the baffle withdraws, the steel plate needs to be locked at this time. Due to the balls, the friction force of the steel plate is small, and there is a problem of insufficient locking stability of the steel plate during the processing, and it is also difficult to meet the installation of the pushing mechanism and the locking mechanism. In addition, traditional steel plate grooving is a switching position grooving operation for single-sided milling of the steel plate. After one end face of the steel plate is processed, the other end face is switched. The end faces are all positioned by the baffle of the groove device, and there are tolerances between the two opposite end faces of the steel plate, resulting in the inability to guarantee the parallelism of the two formed grooves. There is a relative deviation during the subsequent tube forming, affecting the qualified rate of tube forming. In addition, after the tube is formed, axial splicing between the tubes is also required, and the traditional method cannot meet the relative accuracy of the four end faces of the steel plate. Summary of the Invention

[0064] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0065] The following further elaborates on the present application with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the relevant invention and not for limiting the invention. Additionally, it should be noted that for the sake of description, only parts related to the relevant invention are shown in the drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0066] The invention provides a steel plate milling beveling feeding and discharging device, which is used for conveying steel plates to beveling equipment. The feeding end of the beveling equipment is provided with a baffle with lifting displacement for positioning the steel plates.

[0067] This beveling equipment belongs to the prior art, that is, when the steel plate is transported to the beveling equipment, it is positioned by the baffle, and its beveling spindle has adjustable displacement. After the baffle is positioned, it sinks, and after the beveling spindle is moved and positioned, linear beveling is performed. The baffle structure and spindle displacement structure of this type of table-type beveling equipment can be referred to the patent with authorization announcement number CN212599179U. It will not be described in detail here.

[0068] In this case, refer to Figures 1 to 5 As shown, it includes at least two parallel and spaced steel plate supply rail frames 100, that is, Figure 4 and Figure 5 As shown, at least two steel plate supply track racks are used in combination.

[0069] like Figures 1 to 10 As shown, the steel plate supply track frame 100 includes a support platform body 1 with a sink trough, a steel plate pushing mechanism 2 with linear displacement is provided on one side of the support platform body 1, and a material blocking mechanism 3 with linear adjustment displacement is provided on the other side, and at least one roller support track mechanism 4 with lifting displacement is provided in the sink trough.

[0070] The steel plate pushing mechanism 2 includes an active slide 21 and a driven slide 22 elastically floatingly connected, and a bidirectional floating trigger part 23 arranged between the active slide and the driven slide. A linear driving source 210 is provided on the active slide 21, and a steel plate clamping part 220 with a lifting displacement for clamping the steel plate is provided on the side of the driven slide 22 away from the active slide. The bidirectional floating trigger part 23 includes a bidirectional trigger controller 230 communicatively connected to the linear driving source, a first floating monitoring part 231 cooperating with the bidirectional trigger controller for monitoring the relative pushing stroke of the active slide to the driven slide, and a second floating monitoring part 232 for monitoring the relative pulling stroke of the active slide to the driven slide.

[0071] The material blocking mechanism 3 includes a material blocking body 30 with lifting and lowering displacement.

[0072] The roller support track mechanism 4 comprises a track body 41 and a plurality of support rollers 42 arranged on the track body 41 at linear intervals.

[0073] Specific implementation process and principle description:

[0074] The steel plate milling bevel feeding and discharging device has the function of driving the feeding and discharging of the steel plate, that is, realizing the pushing and pulling operations, and also has a two-way positioning function.

[0075] First, the feeding and unloading of steel plates are explained.Figure 4 and Figure 5 As shown, after the steel plate is loaded, it is supported on at least two steel plate supply track racks 100, that is, a number of steel plate supply track racks 100 as shown in Figure 4 and Figure 5 are used in combination. At this time, the roller support track mechanism 4 can be in a raised state or a lowered state, while the steel plate clamping part 220 is in a lowered state, which is lower than the plane where the support surface of the support table body 1 is located.

[0076] When pushing the steel plate, the roller support track mechanism 4 is raised, and through the linear displacement of the steel plate pushing mechanism 2, the steel plate clamping part 220 is raised after leaving the projection area of the steel plate. The steel plate pushing mechanisms 2 on at least two steel plate supply track racks 100 push the steel plate towards the beveling device, so that the end face of the steel plate is flush with the baffle.

[0077] After the steel plate is pushed in place, the roller support track mechanism 4 descends, so that the steel plate is supported on the support table body 1, and the steel plate is clamped and locked by the steel plate clamping part 220. In this way, the requirements for pushing and locking the steel plate are met.

[0078] It should be noted that under the driving action of the linear drive source 210 of the active slide 21, there is a relative floating displacement between the driven slide and the active slide. During the pushing process of multiple steel plate clamping parts 220, after the steel plate is subjected to the acting force of the baffle, it will generate a reverse thrust on the steel plate clamping part 220. This thrust causes the distance between the driven slide and the active slide to decrease, which is monitored by the first floating monitoring part 231. When the distance triggers the two-way trigger controller 230, the linear drive source 210 of the current active slide 21 stops, and the others that have not been triggered continue to run until they are triggered. In this way, the requirement for the end face of the steel plate to be pushed in place and flush is met.

[0079] When pulling the steel plate, there are two operations. The first is unloading, and the second is positioning and reversing pulling.

[0080] Among them, when unloading, the roller support track mechanism 4 is jacked up, and the steel plate clamping part 220 clamps the current steel plate and pulls it away from the beveling device.

[0081] When performing positioning and reversing pulling, after the front-end steel plate is processed, the driving baffle mechanism 3 abuts and positions the baffle body 30 on the side of the steel plate away from the processing end. After positioning, the baffle body 30 sinks. At this time, the current steel plate is turned over so that the processed end of the steel plate is fed in the direction away from the beveling device. At this time, the current loaded steel plate is pushed until the baffle body 30 is separated from the projection area of the steel plate. After several baffle bodies 30 are raised, the steel plate clamping part 220 clamps and displaces the side of the steel plate away from the beveling device, so that the processed end face of the steel plate abuts and is flush with the baffle body 30.

[0082] By operating in this way, the reference positioning requirements of the two opposite end faces are met, the positioning requirements of the steel plate based on the machined end face are realized, and the relative parallelism accuracy after beveling of the two end faces is ensured.

[0083] It should be noted that during the pulling process of the driven slide 22 by the driving slide 21, when the material blocking body 30 blocks the steel plate, a force will be generated on the driven slide 22, causing the floating interval between the driven slide 22 and the driving slide 21 to become larger. When the two-way trigger controller 230 is triggered, the linear drive source 210 of the current driving slide 21 stops, and the others that have not been triggered continue to run until triggered, so as to meet the requirement that one end of the processed steel plate is flush with a number of material blocking bodies 30. At this time, the beveling device can bevel the current end of the steel plate.

[0084] In a specific embodiment, as Figure 6 shown, the two-way trigger controller 230 is arranged on the driven slide, and the two-way trigger controller 230 has a first contact end 2301 facing the driving slide and a second contact end 2302 facing the steel plate clamping part.

[0085] A floating base 221 is provided on the driven slide, and at least one two-way floating shaft rod 211 penetrating the floating base is provided on the driving slide 21. The first floating monitoring part 231 includes a first elastic body 2311 arranged on the two-way floating shaft rod between the floating base and the driving slide, and a first trigger end 2312 arranged on the driving slide and opposite to the first contact end. The second floating monitoring part 232 includes a second elastic body 2321 arranged on the two-way floating shaft rod between the floating base and the free end of the two-way floating shaft rod, and a second trigger end 2322 arranged on the free end of the two-way floating shaft rod and opposite to the second contact end.

[0086] Specifically, generally, a floating elastic body can be used for the floating connection between the driving slide 21 and the driven slide 22. The first floating monitoring part 231 and the second floating monitoring part 232 can be detected by relative distance detection components, and the two are the involved digital thresholds.

[0087] However, in the actual operation process, due to the differences in light and computing power, false triggering may occur, resulting in the equipment stopping or other situations.

[0088] In this embodiment, a contact monitoring method is adopted. The two-way floating shaft rod 211 passes through the floating base 221, and the two-way elastic floating matching realized by the first elastic body 2311 and the second elastic body 2321 meets the floating force balance in the pushing direction and the pulling direction, so as to meet the relative position accuracy of two-way contact triggering, and at the same time, the fatigue resistance is also improved.

[0089] During the specific operation process, the active slide 21 generates a driving force on the driven slide 22, compressing the first elastic body 2311, thereby realizing the contact and separation of the first floating monitoring part 231. When the active slide 21 generates a pulling force on the driven slide 22, the second elastic body 2321 is compressed, thereby realizing the contact and separation of the second floating monitoring part 232. In this way, both are relatively reliable under the floating triggering force, and the triggering stability and reliability are guaranteed.

[0090] In a specific embodiment, as Figure 8 and Figure 9 shown, the driven slide 22 is provided with a lifting sliding carrier plate 222 with lifting displacement and a lifting drive source 223 that is drivingly connected to the lifting sliding carrier plate 222.

[0091] The steel plate clamping part 220 includes a clamping carrier plate 2201 slidably fitted on the lifting sliding carrier plate 222 and a floating connecting body 2202 provided between the clamping carrier plate 2201 and the lifting sliding carrier plate. The clamping carrier plate is provided with a top clamping end 2203 and a bottom clamping end 2204 with a lifting driving body at the bottom of the top clamping end.

[0092] Specifically, after the steel plate is placed, there are the horizontal position where it is supported by the support surface of the support table body 1 and the horizontal position where it is supported by the roller support track mechanism 4 with the lifted rollers 42. There is a relative positional difference between the two.

[0093] And during the material discharging process, there is the driving of the lifting roller support track mechanism 4. Therefore, when the steel plate clamping part 220 needs to release first and then adjust the position for clamping, operations such as adjusting the position for alignment are very cumbersome.

[0094] In this case, the design of the clamping carrier plate 2201 is adopted. Under the action of the floating connecting body 2202, it can realize the coordination between the top clamping end 2203 and the bottom clamping end 2204. That is, when the steel plate is clamped, the lifting displacement of the steel plate will be transmitted to the floating connecting body 2202. In this way, the follow-up clamping requirement for the change of the steel plate support surface can be met without releasing the steel plate.

[0095] In a specific embodiment, the side wall of the support table body 1 that is mating with the steel plate pushing mechanism is provided with a tooth row 10.

[0096] The linear drive source 210 includes an active rotary power part 2101 provided on the active slide and a meshing gear disc 2102 provided on the active rotary power part and meshing and drivingly connected with the tooth row.

[0097] That is, the transmission method of gear meshing with the tooth row is adopted. Of course, adopting other linear drive structures is also within the protection scope of this case.

[0098] In a specific embodiment, asFigure 10 As shown, the material stop mechanism 3 includes a material stop slider 31, a pivot stop arm 32 pivotally connected to the material stop slider, and a stop arm drive portion 33 drivingly connected to the pivot stop arm. The material stop body 30 is provided at the free end of the pivot stop arm.

[0099] That is, the pivot stop arm 32 is driven to swing by the stop arm drive portion 33, so that the material stop slider 31 can meet the driving requirements of rising and sinking, and can avoid the steel plate.

[0100] In a specific embodiment, a material stop slide rail 11 for slidably connecting the material stop slider is provided on the side wall of the support table main body 1 for mating with the material stop mechanism. Scale marks are provided on the material stop slide rail. A material stop locking portion 311 for locking the material stop slider relative to the material stop slide rail and an indicating body 312 for cooperating with the scale marks are provided on the material stop slider 31.

[0101] The material stop locking portion 311 can lock between the material stop slider and the material stop slide rail, and relative fixing structures such as bolts, pins, and locking clips can be used. The indicating body 312 can record the current position, which is convenient for position reset adjustment.

[0102] In a specific embodiment, as Figure 3 shown, the roller support track mechanism 4 is provided with a lifting position drive mechanism 5 on the support table main body.

[0103] The lifting position drive mechanism 5 includes at least two rocker drive bodies 50 at the bottom of the support table main body. The rocker drive body 50 includes a rocker pivot seat 51 and at least one track rocker 52 pivotally connected to the rocker pivot seat. The free end of the track rocker passes through the support table main body and is pivotally connected to the track main body.

[0104] At least one rocker drive body is provided with a telescopic drive source 53. The telescopic drive source 53 includes a telescopic source carrier seat provided at the bottom of the support table main body and a telescopic drive body pivotally connected to the telescopic source carrier seat. The free end of the telescopic drive body is pivotally connected to the corresponding track rocker.

[0105] That is, the cooperation of several rocker drive bodies 50 is used to realize the linkage with the track main body 41. Driven by the telescopic drive source 53 of one rocker drive body, the lifting drive of the track main body 41 is realized.

[0106] Of course, several jacking cylinders and a screw rod driving platform can also be used to drive its lifting displacement. As long as the structure can meet the requirements of driving its lifting displacement, it is within the protection scope of this case.

[0107] In a specific embodiment, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5As shown, the steel plate supply track frame on any side is provided with a plurality of side stop rollers 6 which are spaced apart along the linear direction of the steel plate supply track frame.

[0108] Specifically, the steel plate generally has opposite end faces milled, and the end face to be processed is positioned by abutting against the baffle plate, and the end face after processing is positioned by abutting against the material blocking mechanism. Both methods can achieve the positioning of the relative end faces.

[0109] When the adjacent end face to the machined end face needs to be processed, the side blocking roller 6 is used to achieve guidance, so that the two adjacent end faces of the right-angle end can be referenced to each other.

[0110] The feeding and discharging control method of the steel plate milling bevel feeding and discharging device of the present invention is described as follows:

[0111] Embodiment 1

[0112] Push material control, automatic push material positioning and ejection for single-side milling of steel plates:

[0113] First, in the initial state, the roller support track mechanism, the steel plate clamping part and the material stopper mechanism are in an avoidance position lower than the support surface of the support platform body. At this time, the placement of the steel plate will not collide with the roller support track mechanism, the steel plate clamping part and the material stopper mechanism, effectively preventing the roller support track mechanism, the steel plate clamping part and the material stopper mechanism from being damaged by collision.

[0114] Next, place the steel plate on the supporting platform body of at least two steel plate supply track frames. The steel plates are generally large in size and will be hoisted or installed. Since the roller support track mechanism, steel plate clamping part and material blocking mechanism are all sunk, there is no need for more precise positioning and placement, and the placement operation is more convenient.

[0115] After the steel plate is placed, the driving roller support track mechanism is lifted to a level where the support roller is located above the support plane of the support platform body, and the steel plate pushing mechanism is adjusted through linear displacement to a projection area where the steel plate clamping portion is separated from the steel plate.

[0116] The plane of the support platform body is in surface contact with the steel plate, which has relatively reliable support stability, but the friction force under pushing is relatively large, so the steel plate is lifted by a roller support track mechanism and then supported by a plurality of support rollers 42, so that the required pushing force is relatively small. The steel plate pushing mechanism needs to be moved to an area where the lifting will not contact the steel plate.

[0117] When the steel plate is pushed, the steel plate clamping part rises and moves toward the groove equipment until the end face of the steel plate abuts against the baffle of the groove equipment, and the first floating monitoring part triggers the linear drive source to stop driving.

[0118] Specifically, a number of steel plate clamping parts 220 push the steel plate. When the steel plate pushed by the current steel plate clamping part 220 abuts against the baffle, its reverse force will cause the gap between the active slide 21 and the driven slide 22 to become smaller. When the trigger position of the first floating monitoring part is reached, the drive of the current linear drive source is stopped, and the remaining steel plate clamping parts 220 that have not reached the trigger continue to advance until the trigger stops.

[0119] This meets the automated drive requirement of pushing the device flush with the baffle, and triggering the drive stop can effectively protect the drive source.

[0120] When the steel plate is pushed into place, the driving roller support track mechanism descends until the steel plate is supported on the support platform body, and the steel plate clamping part clamps and fixes the current steel plate.

[0121] Specifically, at this time, the steel plate is stably supported by the supporting surface of the support platform body with a large friction force, and the steel plate is clamped and locked by the steel plate clamping part. This meets the stability of the steel plate during groove processing, and no additional external fixing structure is required to lock the steel plate.

[0122] During the beveling operation, the baffle of the beveling equipment is lowered to carry out beveling processing; it should be noted that the baffle is a positioning structure that meets the requirements of the processing end face of the steel plate. After meeting the relative positioning requirements, it needs to sink to avoid the milling spindle, and the milling spindle has a linear milling displacement parallel to the linear direction of the processing end face, and a linear adjustment displacement toward the processing end face for adjusting the relative position to control the size of the bevel. The adjustment displacement of the above beveling equipment belongs to the prior art and will not be described in detail here. Equipment that meets the requirements of general beveling processing is applicable to this solution.

[0123] Finally, after the steel plate beveling is completed, the driving roller supports the track mechanism to lift up, and the steel plate clamping part clamps the steel plate to separate from the beveling equipment. That is, after the processing is completed, the steel plate clamping part pulls the steel plate so that it can be withdrawn from the beveling equipment. When unloading the steel plate, the steel plate clamping part loosens the steel plate and withdraws.

[0124] Embodiment 2

[0125] Material pulling control, automatic material pulling positioning and material withdrawal for relative end face milling of the steel plate positioning reference end face:

[0126] When the steel plate has a reference end face, the material is positioned by drawing the end face opposite to the reference end face.

[0127] With the reference end face as the reference, after the reference end face and the baffle are flushly abutted through push control, the baffle body rises and moves to abut against the side of the steel plate away from the processing end, and the current position of the baffle mechanism is recorded.

[0128] That is, the positioning relative to the end face to be processed is performed using a plurality of material blocking mechanisms 3 with reference to the reference end face.

[0129] Then the steel plate is turned relative to the end face, that is, the reference end face of the steel plate is turned away from the beveling equipment, and the end face to be processed is turned toward the beveling equipment. After turning, the steel plate is supported on the support table body, and the lifting roller supports the track mechanism and the steel plate clamping part. The steel plate clamping part pushes the current steel plate to the projection area to disengage from the material blocking mechanism.

[0130] It should be noted that the main shaft of the groove equipment has the ability to move away from the steel plate, and provides displacement space for the steel plate through its away displacement. It can also be positioned by a baffle and then locally adjusted by the steel plate pushing mechanism 2 to ensure that the baffle mechanism is exposed relative to the steel plate.

[0131] At this time, the material blocking mechanism is lifted at its recorded position, and the steel plate clamping part clamps the steel plate and moves away from the groove equipment direction until the end face of the steel plate abuts against the material blocking body of the material blocking mechanism.

[0132] That is, the recorded position of the material blocking mechanism is reproduced, and its jacking is used for position limit reference. At this time, the steel plate clamping part clamps the steel plate and moves away from the side of the groove equipment until the second floating monitoring part triggers the linear drive source to stop driving.

[0133] In this way, the material blocking mechanism can be flushly positioned on one side of the pulling direction of the steel plate. Then, the driving roller support track mechanism is lowered until the steel plate is supported on the support platform body, and the steel plate clamping part clamps and fixes the current steel plate.

[0134] Then the groove processing is carried out by the groove equipment. At this time, the parallelism of the groove end faces of the two opposite end faces of the steel plate is guaranteed, and the quality of the pipe curling and forming welding at the rear end is guaranteed.

[0135] After the steel plate groove is completed, the driving roller supports the track mechanism to lift up, and the steel plate clamping part clamps the steel plate and separates it from the groove equipment. This material withdrawal process is consistent with the push-controlled material withdrawal.

[0136] Embodiment 3

[0137] A steel plate supply track frame on any side is provided with a plurality of side stop rollers which are arranged at intervals along the linear direction of the steel plate supply track frame.

[0138] Adjacent edge push control, automatic material pulling positioning and material withdrawal for adjacent end face milling of the steel plate positioning reference end face:

[0139] After the reference end face of the steel plate is processed, the steel plate clamping part releases the steel plate and sinks after avoiding displacement, turning the steel plate on the roller support track mechanism so that the end face to be processed adjacent to the groove forming end face faces the groove equipment, and the groove forming end face is abutted against several of the side stop rollers.

[0140] While the steel plate is kept in contact with the side stop rollers, the steel plate clamping part pushes the steel plate so that the current end face of the steel plate to be grooved abuts against the stopper of the groove device, and the first floating monitoring part triggers the linear drive source to stop driving. In this way, the positioning and stopping accuracy requirements of the adjacent edge relying on the reference end face of the steel plate can be guaranteed.

[0141] The driving roller support track mechanism is lowered until the steel plate is supported on the support platform body, and the steel plate clamping part clamps and fixes the current steel plate; the baffle of the groove equipment is lowered to perform groove processing.

[0142] At this time, it is ensured that the reference end face of the steel plate forms a right angle with the groove end of the adjacent edge end face after current processing, and the forming accuracy is relatively high, which meets the welding reliability of the connection welding between the two pipe bodies after the pipe body is formed.

[0143] Finally, after the steel plate groove is completed, the driving roller supports the track mechanism to be lifted, and the steel plate clamping part clamps the steel plate to separate from the groove device. The separation operation is similar to that of the first and second embodiments.

[0144] From the above description, it can be found that the requirements for automated push-pull operation of steel plate groove forming in and out are met, while the requirements for stability during steel plate groove forming are met, and the accuracy of steel plate groove forming is guaranteed. It can realize the push-feed positioning and pull-feed positioning of the steel plate relative to the two end faces, ensure the parallelism of the two end face forming grooves, and improve the butt weld accuracy of the steel plate rolled forming tube body, and improve the qualified rate of welded tube body forming. It has an edge guide to realize the feeding position reference of the two adjacent right-angle end faces of the steel plate, so that the right angle of the forming groove of the adjacent end faces is regular, meeting the axial welding accuracy requirements of the rear end tube body.
