Description

Technical Field

[0001] The present application relates to the technical field of rotary flattening equipment, and in particular to an end plate rotary flattening equipment and a material feeding and discharging method thereof. Background Art

[0002] ‌Flange end plate‌ is a connecting component used for flange ends, usually made of square steel plates with a hole in the middle for easy connection with other components. When producing flange end plates, the outer shape is first cut out, and then the inner circle is punched out using a punching device. Then, it needs to be ground using a flattening device to make the surface of the end plate smooth.

[0003] Existing leveling equipment requires a dedicated loading and unloading structure for loading and unloading, and the frequency of loading and unloading is often periodic. When producing parts such as end plates, for example, different end plates may require different degrees of leveling, so the actual intervals between each end plate may be different, which requires coordinated loading and unloading frequencies, which also requires relatively high electronic control requirements, indirectly increasing the cost of the equipment. To this end, an end plate leveling device and a feeding and unloading method thereof are proposed to solve the feeding and unloading problems of the leveling device. Summary of the invention

[0004] The purpose of the present application is to provide an end plate flattening device and a material feeding and discharging method thereof.

[0006] As a preference, the correction part is rotatably arranged, and when the material moves forward and acts on the correction part, the correction part rotates to avoid.

[0007] Preferably, a pair of hinge shafts are provided on the top of the correction part, and the correction part is rotatably installed through the hinge shafts. The hinge shaft is provided with a limiting plate on the side of the bottom center facing the feeding direction, and the limiting plate limits the correction part from rotating in the feeding direction.

[0008] As a preferred embodiment, the bottom of the correction part is solid and the top is hollow, the connecting line between each pair of the correction parts is perpendicular to the feeding direction of the conveying mechanism, and the spacing between each pair of the correction parts is greater than or equal to the width of the material; the midpoint of the connecting line of the centers of each pair of the correction parts is aligned with the center of the leveling mechanism.

[0009] As a preference, the top of the correction part is installed by a one-way bearing, and the correction part includes a plurality of windmill-shaped blades, which rotate to avoid when the material passes in the forward direction, and resist against the blades when the material meets in the reverse direction.

[0010] Preferably, the correction part is installed by an elastic part, and a guide surface is provided at the bottom of the correction part on the side facing the feeding direction, and when the material moves forward, it acts on the guide surface to make the correction part move horizontally to avoid; when the material acts on the correction part in the reverse direction, the two cancel each other out.

[0011] Preferably, the conveying mechanism comprises a plurality of conveying parts, wherein the conveying parts are composed of conveying rollers and driving members arranged at intervals, and a correcting part is arranged at the edge of the conveying roller near the leveling mechanism, and the correcting part is arranged between two adjacent conveying rollers, and the top height of the correcting part is greater than the height of the top of the conveying roller; an adjustment structure is arranged at the bottom of the correcting part, and the adjustment structure comprises an adjustment groove perpendicular to the feeding direction of the conveying mechanism, and the correcting part is suitable for sliding adjustment in the adjustment groove to adjust the distance between a pair of the correcting parts.

[0012] As a preference, the conveying part includes a first conveying part, a second conveying part and a third conveying part, the first conveying part is suitable for transferring materials from other process equipment, the second conveying part and the third conveying part are respectively arranged on both sides of the leveling mechanism, and a loading assembly is arranged between the first conveying part and the second conveying part, and the loading assembly includes a rotatably arranged loading plate, a rotating part for rotatably installing the loading plate, an electromagnetic part arranged on the loading plate, and a lifting part for driving the loading plate.

[0013] As a preference, the adjustment structure also includes an elastic member and a tightening groove, and a tightening protrusion is provided at the bottom of the correction portion. When the tightening protrusion is screwed into the tightening groove, it is rotated toward the feeding direction to be in a locked state, and is rotated against the feeding direction to be in an open state; the tightening grooves are arranged in multiple locations at intervals at the bottom of the adjustment groove.

[0014] On the other hand, the present application provides an end plate feeding and discharging method, comprising the following steps: a. Material feeding: The materials are transferred to the feeding mechanism through a roller conveyor belt and grabbed by the feeding mechanism.

[0015] b. Positioning of the material: The material enters the correction component and is then transferred to the leveling position of the leveling mechanism. The correction component is reset at this time. During the process, the correction part is deformed to allow the material to pass through. Subsequently, the leveling mechanism operates to clamp the material.

[0016] c. Flattening: The flattening mechanism then flattens the workpiece to make the surface of the workpiece smooth.

[0017] d. Material discharge: the flattened material remains at the flattening position, and the correction component moves with the next material and finally reaches the flattening position. During the process, the correction part acts on the material that previously stayed at the flattening position and causes it to discharge.

[0018] Compared with the prior art, the beneficial effects of this application are: Through the set feeding mechanism, the transverse moving component and the fixed component are used to drive the loading. When leveling, the transverse moving component is reset first to allow the fixed component to avoid it, preventing the fixed component and the leveling mechanism from acting. After the leveling is completed, the fixed component grabs the next material, and then the transverse moving component drives the second material to be loaded. During the process, the correction part on the outlet side and the previous material act. Since the materials are unidirectional, when the second material is loaded, the first material is also unloaded. Therefore, only one complete loading equipment is set to complete the entire loading and unloading process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0033] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0034] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0035] Example: Reference Figures 1 to 11As shown, this embodiment proposes an end plate flattening device, including a conveying mechanism, a flattening mechanism and a feeding mechanism 4, the feeding mechanism 4 includes a fixing component, a transverse movement component and a correction component 5; the conveying mechanism is suitable for conveying the material 11 to the entrance of the flattening mechanism, the feeding mechanism 4 is suitable for grabbing the material 11 through the fixing component, and continuing to push the material 11 to the flattening position of the flattening mechanism through the transverse movement component; the correction component 5 includes a correction part 16 for unidirectional material transfer in the feeding direction, at least two correction parts 16 are arranged at intervals, the correction part 16 avoids when the material 11 passes through in the feeding direction, so that the material 11 passes; when the material 11 acts on the correction part 16 in the opposite direction of the feeding direction, the correction part 16 does not avoid, so that the material 11 moves and leaves the flattening mechanism.

[0036] When a general leveling mechanism is in operation, it generally loads and unloads materials through two separate loading and unloading structures. On the one hand, the separate loading and unloading structures increase the equipment cost, and on the other hand, the failure rate increases due to the increase in processes. The feeding mechanism 4 of this embodiment grabs the material 11 through the fixed component set, and loads the material through the transverse component; when leveling, the transverse component is reset first to allow the fixed component to avoid, preventing the fixed component and the leveling mechanism from acting; after the leveling is completed, the fixed component grabs the next material 11, and then the transverse component drives the second material 11 to be loaded. During the process, the correction part 16 on the outlet side acts on the previous material 11. Since the material 11 is a one-way material, when the second material 11 is loaded, the first material 11 is also unloaded, thereby completing the entire loading and unloading process.

[0037] like Figure 4 As shown, the flattening mechanism of this embodiment preferably includes a flattening base 6 and a flattening part 8, and the flattening part 8 includes a flattening roller 9. After the material 11 is on the flattening base 6, the flattening base 6 rises (it can be raised and lowered by setting a hydraulic cylinder, etc.) until the material 11 contacts the flattening roller 9 and stops rising. At this time, the flattening roller 9 starts to rotate and flattens. During the process, the friction between the material 11 and the flattening roller 9 can reduce the rotation of the material 11, but the material 11 will still rotate slightly. After the flattening is completed, the flattening base 6 is reset, and the feeding mechanism 4 transmits the next material 11, and the correction component 5 on the feeding mechanism 4 pushes the previous material 11 away to discharge the material.

[0038] Correction component 5 Figure 4 , Figure 5 as well as Figures 9 to 11 As shown, it includes a longer feeding plate 18, two correction parts 16 are set at the end and the middle of the feeding plate 18, and then an electromagnetic part 17 is set between the two correction parts 16, and the transverse movement component directly drives the feeding plate 18 to move.

[0039] For transverse components, please refer to Figure 5 , Figure 6 As shown, it includes a fixing frame 10, which is installed at the edge of the second conveying part 3. A cylinder is set in the middle of the fixing frame 10, and the piston rod of the cylinder is connected to the correction component 5. In order to ensure stability, the correction component 5 is also provided with two guide rods (refer to Figure 6 ), so that the correction component 5 can be moved horizontally as a whole through the cylinder.

[0040] Two specific solutions for correcting the one-way material transfer of the structure are proposed below.

[0041] The first type: the correction part 16 is arranged to rotate, and when the material 11 moves forward and acts on the correction part 16, the correction part 16 rotates to avoid. Here, the following two preferred implementation schemes are further provided.

[0042] (1) A pair of hinge shafts are provided at the top of the correction part 16, and the correction part 16 is rotatably installed through the hinge shafts. A limiting plate is provided at the side of the bottom center of the hinge shaft facing the feeding direction, and the limiting plate limits the rotation of the correction part 16 in the feeding direction. This solution can be referred to Fig. 9 As shown, the block on the left side of the correction part 16 is the limiting plate. When the correction part 16 moves in the reverse direction (that is, when the material 11 acts on the correction part 16 in the reverse direction), the correction part 16 and the limiting plate are against each other, so the material 11 is stuck and cannot pass through. When the material 11 moves to the right, the correction part 16 rotates normally, so it can pass through. This solution can refer to Figures 8 to 11 , Fig. 9 This is a state diagram of the material 11 when the first correction part 16 begins to act. Fig.10 The middle material 11 continues to move forward and reaches between the two correction parts 16. Fig.11 It is a schematic diagram of the material 11 acting in the reverse direction on the second correction part 16. At this time, the correction part 16 is blocked by the electromagnetic part 17 and cannot rotate, so that the material 11 cannot pass in the reverse direction. Of course, the electromagnetic part 17 here can also be replaced by a limiting plate, but the electromagnetic part 17 can be set here to act as a limiting plate to prevent the correction part 16 from rotating.

[0043] It is worth mentioning that Figures 8 to 11 The middle limiting plate and the electromagnetic part 17 are similar or identical in appearance, and Figure 8 In the upper and lower schematic states, the lower one has one less electromagnetic part 17, that is, the upper one has a total of three limiting plates and electromagnetic parts 17, while the lower one has a total of two. This is to indicate the relatively flexible installation position of the above-mentioned electromagnetic part 17. The electromagnetic part 17 can also replace the limiting plate to perform a limiting effect when it is in a suitable position.

[0044] Furthermore, the bottom of the correction part 16 is solid and the top is hollow, the connecting line between each pair of correction parts 16 is perpendicular to the feeding direction of the conveying mechanism, and the spacing between each pair of correction parts 16 is greater than or equal to the width of the material 11; the midpoint of the connecting line of the centers of each pair of correction parts 16 is aligned with the center of the leveling mechanism. The correction part 16 is only hinged, with the bottom of the correction part 16 being solid and the top being hollow, so that the center of gravity of the correction part 16 is biased downward, so that the initial state of the correction part 16 remains in a naturally drooping state, effectively reducing the problem of the correction part 16 being stuck in the air due to rust, etc.

[0045] (2) The top of the correction part 16 is installed through a one-way bearing. The correction part 16 includes multiple windmill-shaped blades. When the material 11 passes in the forward direction, the blades rotate to avoid it, and when the material 11 contacts in the reverse direction, the blades abut against it. This scheme does not provide a schematic diagram, but it is easy to understand that the one-way bearing allows the blades to rotate in only one direction. Therefore, when the material 11 moves in the forward direction, the blades can rotate and allow the material 11 to pass, but when it moves in the reverse direction, the blades abut against it and prevent it from passing. However, in this scheme, the spacing between the multiple blades must be able to ensure that the material 11 passes completely, so as to prevent the second blade from interacting with the material 11 when the material 11 passes halfway. That is, this scheme has certain limitations.

[0046] The second type: the correction part 16 is installed through an elastic member, and a guide surface is provided at the bottom of the correction part 16 on the side facing the feeding direction. When the material 11 moves forward, it acts on the guide surface to make the correction part 16 move horizontally to avoid; when the material 11 acts on the correction part 16 in the reverse direction, the two cancel each other out. This scheme does not give a specific schematic diagram, but through a simple conception, when the material 11 moves in the reverse direction and acts on the correction part 16, it is vertically connected to the correction part 16, and the force of the reverse movement of the material 11 and the reverse support force of the correction part 16 directly cancel each other out, so the correction part 16 will not rise, and the material 11 will not pass through. On the contrary, when the material 11 moves forward, it acts on the guide surface, and the correction part 16 will be subjected to the upward component force, so the correction part 16 can rise to allow the material 11 to pass through.

[0047] like Figure 1 , Figure 5 , Figure 6As shown, the conveying mechanism includes a plurality of conveying parts, which are composed of conveying rollers and driving parts arranged at intervals. A correction part 12 is arranged at the edge of the conveying roller near the leveling mechanism. The correction part 12 is arranged between two adjacent conveying rollers, and the top height of the correction part 12 is greater than the height of the top of the conveying roller; an adjustment structure 13 is arranged at the bottom of the correction part 12, and the adjustment structure 13 includes an adjustment groove perpendicular to the feeding direction of the conveying mechanism. The correction part 12 is suitable for sliding adjustment in the adjustment groove to adjust the distance between a pair of correction parts 12. In order to facilitate the adjustment and fixation of the correction part 12, the adjustment structure 13 also includes an elastic member and a tightening groove. A tightening protrusion is arranged at the bottom of the correction part 16. When the tightening protrusion is screwed into the tightening groove, it rotates toward the feeding direction to a locked state, and rotates against the feeding direction to an open state; the tightening groove is arranged at multiple intervals at the bottom of the adjustment groove. The positioning of the tightening protrusion and the tightening groove can be understood by association with the thread matching. The feeding direction of the material 11 is fixed. In order to prevent such cooperation from being released by the direction of the material 11, the cooperation direction of the tightening protrusion and the tightening groove is set to rotate toward the feeding direction to a locked state and rotate against the feeding direction to an open state.

[0048] The setting of the correction part 12 has a limiting and guiding effect on the material 11, which can ensure that the general position of the material 11 is in the middle of the conveying mechanism; because the material 11 will rotate when the leveling mechanism is leveling, the initial loading direction of the material 11 is not important, as long as the material 11 is close to the center of the conveying mechanism.

[0049] like Figure 1 As shown, the conveying part includes a first conveying part 1, a second conveying part 3 and a third conveying part 7. The first conveying part 1 is suitable for transferring the material 11 from other process equipment. The second conveying part 3 and the third conveying part 7 are respectively arranged on both sides of the leveling mechanism. A loading assembly 2 is arranged between the first conveying part 1 and the second conveying part 3. The loading assembly 2 includes a rotating loading plate, a rotating member 15 for rotating the loading plate, an electromagnetic part 17 arranged on the loading plate, and a lifting part for driving the loading plate. The loading assembly 2 is a device for transferring materials from other processes to this process. When loading, the loading plate is brought close to the material 11 through the transverse structure, and the material 11 is magnetically attracted by the electromagnetic part 17. Then the rotating member 15 drives the loading plate to rotate 180° and returns to the second conveying part 3 through the transverse structure. Then the loading plate is reset and ready for the next loading.

[0050] The loading assembly 2 is provided with a cylinder 14, which can drive the loading plate to move laterally between the first conveying part 1 and the second conveying part 3. In order to maintain stability, a guide rail 19 is also provided in the moving direction of the loading plate for guidance.

[0051] On the other hand, the present application provides an end plate feeding and discharging method based on the above end plate flattening device, comprising the following steps: a. Material feeding: The materials are transferred to the feeding mechanism through a roller conveyor belt and grabbed by the feeding mechanism.

[0052] b. Positioning of the material: The material enters the correction component and is then transferred to the leveling position of the leveling mechanism. The correction component is reset at this time. During the process, the correction part is deformed to allow the material to pass through. Subsequently, the leveling mechanism operates to clamp the material.

[0053] c. Flattening: The flattening mechanism then flattens the workpiece to make the surface of the workpiece smooth.

[0054] d. Material discharge: the flattened material remains at the flattening position, and the correction component moves with the next material and finally reaches the flattening position. During the process, the correction part acts on the material that previously stayed at the flattening position and causes it to discharge.

[0055] This method can ensure smooth loading and unloading of materials by utilizing the end plate flattening device, so that the flattening device can be used in an assembly line production mode.

[0056] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
