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] The steel plate groove is an operation of grooving the welding part of the workpiece before welding to ensure the welding quality during the welding manufacturing process. The existence of the groove can make the electrode or welding wire better enter the weld, increase the penetration depth and width of the weld, and improve the strength and sealing performance of the welded joint.

[0003] Steel plates have many uses, including dock steel plates, circular tube forming steel plates, 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 milled with slope grooves on at least one pair of opposite edges, and the parallelism of the groove forming on 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, traditional steel plate support tables use 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 the baffle withdraws, the steel plate needs to be locked at this time. Due to the small friction of the steel plate caused by the balls, there is a problem of insufficient locking stability of the steel plate during the processing, and it is difficult to meet the installation of the pushing mechanism and the locking mechanism. In addition, traditional steel plate grooving is a switching position groove 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 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

[0030] 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. Apparently, 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.

[0031] The following further elaborates the present application with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention and not to limit the invention. Additionally, it should be noted that for the convenience of description, only the parts related to the relevant invention are shown in the accompanying 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.

[0032] The present invention provides a steel plate milling slope notch feeding and discharging device for conveying steel plates to a beveling device. A baffle with lifting displacement for positioning the steel plate is provided at the feeding end of the beveling device.

[0033] This beveling device belongs to the prior art. That is, when the steel plate is conveyed onto the beveling device, it is positioned by the baffle. Its beveling main shaft has adjustable displacement. After the baffle is positioned, it sinks. After the beveling main shaft moves and is positioned, linear beveling is performed. For the baffle structure and the main shaft displacement structure of such bench-type beveling devices, reference can be made to the patent with the authorization announcement number CN212599179U. Details will not be elaborated here.

[0034] In this case, with reference to Figures 1 to 5 as shown, it includes at least two parallel and spaced-apart steel plate supply track frames 100, that is, as Figure 4 and Figure 5 shown, the combination use of at least two steel plate supply track frames is carried out.

[0035] As Figures 1 to 10 shown, the steel plate supply track rack 100 includes a support table body 1 with a sunken groove. A steel plate pushing mechanism 2 with linear displacement is provided on one side of the support table body 1, and a material blocking mechanism 3 with linearly adjustable displacement is provided on the other side. At least one roller support track mechanism 4 with lifting displacement is provided in the sunken groove.

[0036] The steel plate pushing mechanism 2 includes an active slide table 21 and a driven slide table 22 that are elastically and floatingly connected, and a two-way floating trigger part 23 arranged between the active slide table and the driven slide table. A linear drive source 210 is provided on the active slide table 21. A steel plate clamping part 220 with lifting displacement for clamping the steel plate is provided on the side of the driven slide table 22 facing away from the active slide table. The two-way floating trigger part 23 includes a two-way trigger controller 230 communicatively connected to the linear drive source, a first floating monitoring part 231 for monitoring the relative pushing stroke of the active slide table to the driven slide table, and a second floating monitoring part 232 for monitoring the relative pulling stroke of the active slide table to the driven slide table.

[0037] The material blocking mechanism 3 includes a material blocking body 30 with lifting displacement.

[0038] The roller support track mechanism 4 includes a track body 41 and a number of support rollers 42 linearly and spacedly arranged on the track body 41.

[0039] Specific implementation process and principle description: The steel plate milling slope and groove 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 of the material, and at the same time has the function of two-way positioning.

[0040] First, the feeding and discharging of the steel plate will be described. As Figure 4 and Figure 5 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 combined and used. At this time, the roller support track mechanism 4 can be in a raised state or a lowered state, and the steel plate clamping part 220 is in a lowered state, which is lower than the plane of the support surface of the support table body 1.

[0041] 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 groove-opening device, so that the end face of the steel plate is flush with the baffle.

[0042] After the steel plate is pushed in place, the roller support track mechanism 4 descends, so that the steel plate is supported on the main body 1 of the support table, 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.

[0043] It should be noted that under the driving action of the linear driving source 210 on 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 affected by the force of the baffle, it will generate a reverse thrust on the steel plate clamping part 220, and this thrust causes the distance between the driven slide and the active slide to decrease. Monitored by the first floating monitoring part 231, when the distance triggers the two-way trigger controller 230, the linear driving source 210 of the current active slide 21 stops, and the others that have not been triggered continue to run until triggered. In this way, the requirement for the end face of the steel plate to be pushed in place to be flush is met.

[0044] When performing the pulling operation on the steel plate, there are two types of work. The first is unloading, and the other is positioning and reversing pulling.

[0045] Among them, when unloading, the roller support track mechanism 4 is lifted, and the steel plate clamping part 220 clamps the current steel plate and pulls it away from the groove-opening device.

[0046] 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 groove-opening device. At this time, the current fed steel plate is pushed until the projection area of the baffle body 30 and the steel plate is separated. After several baffle bodies 30 are raised, the steel plate clamping part 220 clamps the steel plate and displaces it on the side away from the groove-opening device, so that the processed end face of the steel plate abuts and is flush with the baffle body 30.

[0047] By operating like this, the requirement for reference positioning of the two opposite end faces is met, the positioning requirement of the steel plate based on the processed end face is realized, and the relative parallel accuracy after grooving of the two end faces is ensured.

[0048] It should be noted that when the active slide 21 pulls the driven slide 22, when the baffle body 30 blocks the steel plate, it will generate a force on the driven slide 22, making the floating interval between the driven slide 22 and the active slide 21 larger. When the two-way trigger controller 230 is triggered, the linear driving source 210 of the current active slide 21 stops, and the others that have not been triggered continue to run until triggered. In this way, the requirement for the processed end of the steel plate to be flush with several baffle bodies 30 is met. At this time, the groove-opening device can groove the current end of the steel plate.

[0049] In a specific embodiment, such as Figure 6As shown, the bidirectional trigger controller 230 is arranged on the driven slide, and the bidirectional trigger controller 230 has a first contact end 2301 toward the active slide and a second contact end 2302 toward the steel plate clamping part.

[0050] A floating base 221 is provided on the driven slide, and at least one bidirectional floating shaft 211 penetrating the floating base is provided on the active slide 21. The first floating monitoring part 231 includes a first elastic body 2311 arranged on the bidirectional floating shaft and located between the floating base and the active slide, and a first trigger end 2312 arranged on the active slide and opposite to the first contact end. The second floating monitoring part 232 includes a second elastic body 2321 arranged on the bidirectional floating shaft and located between the floating base and the free end of the bidirectional floating shaft, and a second trigger end 2322 arranged on the free end of the bidirectional floating shaft and opposite to the second contact end.

[0051] Specifically, a floating elastic body is generally used to achieve floating connection between the active slide 21 and the driven slide 22. The first floating monitoring unit 231 and the second floating monitoring unit 232 can be detected by relative spacing detection components, and both are related digital thresholds.

[0052] However, in actual operation, differences in light and computing power may lead to false triggering, causing the device to shut down or other situations.

[0053] In this embodiment, a contact monitoring method is adopted, and a two-way floating shaft 211 is used to pass through the floating base 221. The two-way elastic floating connection realized by the first elastomer 2311 and the second elastomer 2321 satisfies the balance of floating force in the pushing direction and the pulling direction. In this way, the relative position of the two-way contact trigger is satisfied, and the fatigue resistance is also improved.

[0054] During the specific operation, the active slide 21 generates a pushing 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, and 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 in receiving the floating trigger force, and the reliability of the trigger stability is guaranteed.

[0055] In a specific embodiment, Figure 8 and Figure 9 As shown, a lifting sliding carrier plate 222 with lifting displacement and a lifting driving source 223 drivingly connected to the lifting sliding carrier plate 222 are provided on the driven slide 22 .

[0056] The steel plate clamping part 220 includes a clamping carrier plate 2201 slidably fitted on the lifting and sliding carrier plate 222, and a floating connection body 2202 provided on the clamping carrier plate 2201 and the lifting and 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.

[0057] Specifically, after the steel plate is placed, there is a horizontal position where it is supported by the support surface of the support table body 1, and a horizontal position where it is supported by the support rollers 42 of the lifted roller support track mechanism 4. There is a relative positional difference between the two.

[0058] During the unloading process, there is a drive for the lifting roller support track mechanism 4. Therefore, when the steel plate clamping part 220 needs to release first and then adjust the positional accuracy for clamping, operations such as adjusting the positional accuracy and alignment are very cumbersome.

[0059] In this case, with the design of the clamping carrier plate 2201, under the action of the floating connection body 2202, it can achieve the coordination between the top clamping end 2203 and the bottom clamping end 2204. That is, when clamping the steel plate, if the steel plate has a lifting displacement, it will be transmitted to the floating connection body 2202. In this way, the follow-up clamping requirement for the change of the support surface of the steel plate can be met without releasing the steel plate.

[0060] In a specific embodiment, a tooth row 10 is provided on the side wall of the support table body 1 that is connected to the steel plate pushing mechanism.

[0061] The linear drive source 210 includes an active rotary power part 2101 provided on the active slide table, and an engagement gear disc 2102 provided on the active rotary power part and meshed and connected with the tooth row for transmission.

[0062] That is, the transmission method of gear meshing with the tooth row is adopted. Of course, other linear drive structures are also within the protection scope of this case.

[0063] In a specific embodiment, as Figure 10 shown, the material blocking mechanism 3 includes a material blocking slider 31, a pivotally connected pivot blocking arm 32 on the material blocking slider, and a blocking arm driving part 33 drivingly connected to the pivot blocking arm. The material blocking body 30 is provided at the free end of the pivot blocking arm.

[0064] That is, the pivot blocking arm 32 is driven to swing by the blocking arm driving part 33, so that the material blocking slider 31 can meet the driving requirements of rising and sinking, and can avoid the steel plate.

[0065] In a specific embodiment, a material blocking slide rail 11 for slidably connecting the material blocking slider is provided on the side wall of the support table body 1 that is connected to the material blocking mechanism. Scale marks are provided on the material blocking slide rail. The material blocking slider 31 is provided with a material blocking locking part 311 for locking the relative position between the material blocking slider and the material blocking slide rail, and an indicating body 312 for cooperating with the scale marks.

[0066] The material stop locking portion 311 can realize the locking between the material stop slider and the material stop rail, and can adopt relatively fixed structures such as pins, latches, and locking clamps, while the indicator 312 can realize the current position recording, which is convenient for position resetting and adjustment.

[0067] In a specific embodiment, Figure 3 As shown, the roller support track mechanism 4 is provided with a lifting and lowering driving mechanism 5 located on the support platform body.

[0068] The lifting drive mechanism 5 includes at least two rocker arm drive bodies 50 located at the bottom of the support platform body. The rocker arm drive body 50 includes a rocker arm pivot seat 51 and at least one track rocker arm 52 pivotally connected to the rocker arm pivot seat. The free end of the track rocker arm passes through the support platform body and is pivotally connected to the track body.

[0069] At least one rocker arm driving body has a telescopic driving source 53, which includes a telescopic source carrier arranged at the bottom of the support platform body, a telescopic driving body pivotally connected to the telescopic source carrier, and a free end of the telescopic driving body is pivotally connected to the corresponding track rocker arm.

[0070] That is, a plurality of coordinated rocker arm driving bodies 50 are utilized to realize linkage with the track body 41, and under the drive of a telescopic driving source 53 of a rocker arm driving body, the lifting and lowering drive of the track body 41 is realized.

[0071] Of course, it is also possible to use a number of lifting cylinders and screw-driven platforms to drive the lifting and displacement of the platform. As long as the structure required to drive the lifting and displacement of the platform is met, it is within the protection scope of this case.

[0072] In a specific embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 5 As 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.

[0073] 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.

[0074] 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.

[0075] The feeding and discharging control method of the steel plate milling bevel feeding and discharging device of the present invention is described as follows: Embodiment 1 Pushing material control, automatic pushing and positioning of the steel plate for single-sided milling and grinding and discharging of the material: First, in the initial state, the roller support track mechanism, the steel plate clamping part, and the material blocking mechanism are in the avoidance position below the support surface of the support table body. At this time, placing the steel plate will not cause impact on the roller support track mechanism, the steel plate clamping part, and the material blocking mechanism, effectively preventing the roller support track mechanism, the steel plate clamping part, and the material blocking mechanism from being damaged by impact.

[0076] Next, place the steel plate on the support table body of at least two steel plate supply track racks. Generally, the steel plate has a large specification and will be hoisted or other methods. Since the roller support track mechanism, the steel plate clamping part, and the material blocking mechanism have all sunk, there is no need for precise positioning and placement, and the placement operation is more convenient.

[0077] After the steel plate is placed, drive the roller support track mechanism to rise until the plane where the support rollers are located is higher than the support plane of the support table body, and the steel plate pushing mechanism is adjusted through linear displacement to the projection area where the steel plate clamping part is separated from the steel plate.

[0078] The plane of the support table body is in surface contact with the steel plate, with relatively reliable support stability. And the frictional force during pushing is large. Therefore, after the roller support track mechanism is used to lift the steel plate, it is supported by several support rollers 42, so that the required pushing force is smaller. And the steel plate pushing mechanism needs to be displaced to an area where the lifting will not contact the steel plate.

[0079] When pushing the steel plate, the steel plate clamping part rises and moves towards the beveling device until the end face of the steel plate abuts against the baffle of the beveling device, and the first floating monitoring part triggers the linear drive source to stop driving.

[0080] Specifically, several steel plate clamping parts 220 push the steel plate. After the steel plate pushed by the current steel plate clamping part 220 abuts against the baffle, its reaction force will make the gap between the active slide table 21 and the driven slide table 22 smaller. When reaching the trigger position degree of the first floating monitoring part, the driving of the current linear drive source stops, and the other steel plate clamping parts 220 that have not reached the trigger continue to advance until they are triggered to stop.

[0081] In this way, it meets the automatic driving requirement of pushing flush with the baffle, and at the same time, triggering the driving stop can effectively protect the drive source.

[0082] When the steel plate is pushed in place, drive the roller support track mechanism to descend until the steel plate is supported on the support table body, and the steel plate clamping part clamps and fixes the current steel plate.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Embodiment 2 Material pulling control, automatic material pulling positioning and material withdrawal for relative end face milling of the steel plate positioning reference end face: When the steel plate has a reference end face, the material is positioned by drawing the end face opposite to the reference end face.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] At this time, the material blocking mechanism is lifted at the recorded position, and the steel plate clamping part clamps the steel plate and moves in the direction away from the beveling device until the end face of the steel plate abuts against the material blocking body of the material blocking mechanism.

[0092] That is, the recorded position of the material blocking mechanism is reproduced, and its lifting is used for position limit reference. At this time, the steel plate clamping part clamps the steel plate and displaces on the side away from the beveling device until the second floating monitoring part triggers the linear drive source to stop driving.

[0093] In this way, the material blocking mechanism realizes flush positioning on the pulling direction side of the steel plate. Then, the driving roller support track mechanism descends until the steel plate is supported on the support table main body, and the steel plate clamping part clamps and fixes the current steel plate.

[0094] Then, beveling processing is carried out on the beveling device. At this time, the parallelism of the beveled end faces of the two opposite end faces of the steel plate is guaranteed, and the welding quality of the tube body curling and forming at the rear end is guaranteed.

[0095] After the beveling of the steel plate is completed, the driving roller support track mechanism is lifted, and the steel plate clamping part clamps the steel plate and separates it from the beveling device. This unloading process is the same as the unloading of the pushing control.

[0096] Embodiment III On any one side of the steel plate supply track, a number of side blocking rollers are arranged at intervals along the linear direction of the steel plate supply track.

[0097] For adjacent side pushing control, automatic pulling positioning and unloading for milling the adjacent end faces of the positioning reference end face of the steel plate are carried out: After the machining of the reference end face of the steel plate is completed, the steel plate clamping part releases the steel plate and avoids displacement and then sinks, turns the steel plate on the roller support track mechanism, so that the to-be-machined end face adjacent to the beveled forming end face faces the beveling device, and the beveled forming end face abuts against a number of the side blocking rollers.

[0098] While maintaining the state of the steel plate in contact with a number of side blocking rollers, the steel plate clamping part pushes the steel plate so that the current beveled end face of the steel plate abuts against the baffle of the beveling device, and the first floating monitoring part triggers the linear drive source to stop driving. In this way, the positioning stop accuracy requirements for the adjacent side relying on the reference end face of the steel plate can be guaranteed.

[0099] The driving roller support track mechanism descends until the steel plate is supported on the support table main body, and the steel plate clamping part clamps and fixes the current steel plate; after the baffle of the beveling device descends, beveling processing is carried out.

[0100] At this time, it is ensured that the beveled end of the reference end face of the steel plate and the adjacent end face after current machining form a right angle, and the relative forming accuracy is relatively high, meeting the welding reliability requirements for the connection welding between two tube bodies after tube body forming.

[0101] 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.

[0102] 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.

[0103] The term "comprise" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that includes a list of elements includes not only those elements but also other elements not expressly listed, or also includes elements inherent to such process, method, article, or apparatus / device.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
