Description

Technical Field

[0001] The present application relates to the production of flange accessories, and in particular to a square flange flexible processing production line and a control method. Background Art

[0002] The square flange end plate is a connecting component used for the end of the flange, usually made of a square steel plate with a hole in the middle for easy connection with other components. The square flange end plate production line usually requires a cutting device to cut out the shape of the end plate, then use a stamping mechanism to punch out the inner circle, then use a rotary grinding device for grinding, and finally complete the entire process through beveling to obtain the product.

[0003] In the existing square flange production lines, some production lines with a high degree of automation generally use precision equipment such as robotic arms, which makes the production line cost high and difficult to repair when a fault occurs; in addition, since the time spent on each process on the production line is different, for example, the cutting process is obviously faster, while the spin-grinding process is obviously slower, which leads to the fact that the efficiency of the general production line generally depends on the slowest process. To solve this problem, a square flange flexible processing production line and control method are proposed. Summary of the invention

Material diversion and transfer: the cut material prototypes are conveyed through two or any one of the two stations of the double-station conveying equipment and transferred to the corresponding production line. The cut materials that exceed the rate of subsequent process are stored through the retention mechanism, and after the normal production line is processed, they are re-transferred into the production line for subsequent processing through the transfer mechanism with an extended transfer stroke.

In order to adapt to the retention mechanism, the transfer mechanism only needs to appropriately extend the transfer stroke of the transfer mechanism, so the equipment cost of the production line is easy to control.

[0037] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence.

[0038] The terms "comprising" and "having" in the description and claims of this application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0039] Example:

[0040] Referring to Figures 1 to 12 , this embodiment provides a flexible processing production line for square flanges, including a laser cutting device 1, a double-station conveying device 2, an internal circle processing device 3, a flattening device 4, a bevel processing device 5, and several transfer mechanisms 8 disposed between the devices. Retention mechanisms 6 are disposed between the double-station conveying device 2, the internal circle processing device 3, and the flattening device 4. The retention mechanism 6 is adapted to stack the workpieces 7 and automatically rise / fall according to the number of stacked workpieces 7. The transfer strokes of the two transfer mechanisms 8 located between the double-station conveying device 2, the internal circle processing device 3, and the flattening device 4 are extended, so that the corresponding transfer mechanism 8 directly picks up materials from the retention mechanism 6 and transfers them.

[0041] The function of the retention mechanism 6 is to stack the workpieces 7 that are not processed in time, so that those devices with faster processes can operate normally, thus ensuring better production efficiency. The transfer mechanism 8 itself is a structure for grasping and transferring the workpieces 7 between multiple devices. Obviously, it mainly includes a horizontal movement stroke between two devices and the function of being able to grasp the workpieces 7. In order to make the transfer mechanism 8 work reliably, the transfer mechanism 8 generally grabs and transfers materials periodically. In order to adapt to the retention mechanism 6, the transfer stroke of the transfer mechanism 8 can be appropriately extended, and the corresponding implemented structure is easy to understand. However, stacking the workpieces 7 will cause a problem, that is, after the transfer mechanism 8 picks up the materials, the height of the stacked workpieces 7 will decrease. If the transfer mechanism 8 does not adapt, it may lead to the failure of the transfer mechanism 8 to pick up materials; and if the transfer mechanism 8 wants to be able to recognize the height change after the workpieces 7 are taken away and make a reaction, it requires precise recognition components and additional lifting structures, which will undoubtedly increase the cost. To solve this problem, from another perspective, the retention mechanism 6 is made to correspond to automatic lifting and lowering, so that the workpieces 7 automatically descend when stacked and automatically rise when taken away, so as to ensure that the stacked workpieces 7 are always at the same height or within a height range, making it easier to pick up the workpieces 7.

[0042] It is worth mentioning that referring to Figure 1 , Figure 7 , Fig. 9 and Fig.10 The transfer mechanism 8 appears in the figure, and the structure of the transfer mechanism 8 in these embodiments is not the same. The transfer mechanism 8 in the present application can be understood as a functional component, so its specific structure can change, but its function is to transfer the material 7 from one device to another.

[0043] To solve this problem, refer to Figure 2 , the retention mechanism 6 of this embodiment includes a stacking table that can be raised and lowered, a sensing component for identifying gravity, and a reaction component for lifting and lowering. After the sensing component identifies the change in gravity, it automatically controls the lifting and lowering of the stacking table through the reaction component; the process of each transfer movement of the transfer mechanism 8 is the same, and the two transfer mechanisms 8 located between the double-station conveying device 2 and the inner circle processing device 3 and the flattening device 4 have two transfer procedures: a normal transfer procedure and a transfer procedure that extends the transfer stroke. Among them, the gravity sensing component and the reaction component are not clearly shown. The gravity sensing component is generally set as a pressure sensor, and the reaction component can be set as a driving component such as a cylinder. Or it can also be realized by an elastic member such as a spring, for example, a guide rod is set at the four corners of the stacking table so that the stacking table can be stably lifted and lowered, and a spring is set at the bottom of the stacking table. When the material 7 increases, the spring is compressed, so the stacking table descends, and when the material 7 decreases, the stacking table automatically rises, so the spring here serves as both a gravity sensing component and a reaction component.

[0044] Reference Figure 2 , Figure 3The double-station conveying device 2 of this embodiment includes three conveying mechanisms and a reversing mechanism 24. The three conveying mechanisms are a first conveying mechanism 21, a second conveying mechanism 22 and a third conveying mechanism 23. Two of the conveying mechanisms are used for diverting the material 7, and one conveying mechanism is used for feeding. The conveying surfaces of the two conveying mechanisms for diverting are lower than the conveying surface of the conveying mechanism for feeding. The reversing mechanism 24 includes a chain conveying part 24a that can be raised and lowered and a fixed roller conveying part. The conveying direction of the chain conveying part 24a is the same as that of the conveying mechanism for feeding. The roller conveying part includes two groups of conveying rollers facing the two conveying mechanisms for diverting respectively, and the top surface of the roller conveying part is flush with or higher than the transmission surface of the two conveying mechanisms for diverting; the three conveying mechanisms together form a T-shaped configuration, and the reversing mechanism 24 is arranged on the three conveying mechanisms. The intersection of the conveying mechanism; the chain conveyor 24a is arranged in multiple groups at intervals, and the roller conveyor is arranged in the gap between the multiple groups of chain conveyor 24a; in the initial state, the top surface of the chain conveyor 24a is flush with or lower than the top surface of the first conveying mechanism 21, and at the same time, the top surface of the chain conveyor 24a is higher than the top surface of the roller conveyor. The material 7 is transported to the chain conveyor 24a by the first conveying mechanism 21. The chain conveyor 24a allows the material 7 to continue to move in the conveying direction of the first conveying mechanism 21 for a set distance and then descend until the material 7 contacts the conveying roller. After the corresponding conveying roller transfers the material 7 to the second conveying mechanism 22 or the third conveying mechanism 23, the chain conveyor 24a is reset, and a lifting cylinder is arranged at the bottom of the chain conveyor 24a, and the chain conveyor 24a is lifted and lowered by the lifting cylinder. Its specific working principle is as follows:

[0045] The material 7 starts to be conveyed from the first conveying mechanism 21; in the initial state, the top surface height of the chain conveying part 24a on the reversing mechanism 24 is located above the top surface heights of the second conveying mechanism 22 and the third conveying mechanism 23. At this time, the top surface height of the chain conveying part 24a is the same as or slightly lower than the top surface height of the first conveying mechanism 21. The workpiece can be conveyed to the chain conveying part 24a at this time. When the chain conveying part 24a is in operation, it will continue to move the material 7 a short distance in the conveying direction of the first conveying mechanism 21, so that the workpiece is completely located above the chain conveying part 24a and corresponds to the relative middle position of the second conveying mechanism 22 and the third conveying mechanism 23. At this time, the chain conveying part 24a descends, so that the bottom of the material 7 gradually connects with the support roller 24d, the first conveying roller 24b and the second conveying roller 24c, and this At this time, only one of the second conveying mechanism 22 and the third conveying mechanism 23 is in operation, because each time the material 7 is fed, one material 7 can only go to one production line. Assuming that the second conveying mechanism 22 is turned on this time, the first conveying roller 24b will run together with the second conveying mechanism 22. At this time, the bottom of the material 7 begins to move toward the side of the second conveying mechanism 22 under the action of the second conveying roller 24c, and then enters the production line on the side of the second conveying mechanism 22. In this process, it is obvious that the height of the first conveying roller 24b is at least the same as that of the second conveying mechanism 22, preferably slightly higher, and the height of the first conveying roller 24b needs to be the same as or slightly lower than that of the first conveying mechanism 21. Therefore, the height of the first conveying mechanism 21 is obviously higher than the heights of the second conveying mechanism 22 and the third conveying mechanism 23.

[0046] The purpose of this embodiment is to expand the capacity of only one production line into two production lines, and these two production lines can be produced together, or only one of them can be used. In order to achieve this goal, it is generally necessary to adopt a flexible grasping structure such as a robotic arm, which has a great impact on the initial cost of the entire production line. The reversing mechanism 24 set in this embodiment can realize the turning of the object by simply cooperating with two conveying parts, which can reduce the production line cost.

[0047] A conveying mechanism for transfer is also arranged in the vertical direction of the two conveying mechanisms for diversion, and a reversing mechanism 24 is arranged between the two conveying mechanisms for transfer and the two conveying mechanisms corresponding to the diversion. A retention mechanism 6 is arranged on the other side of the two reversing mechanisms 24 relative to the conveying mechanism, and a transfer mechanism 8 with an extended transfer stroke is arranged corresponding to the retention mechanism 6.

[0048] In order to facilitate the transfer of the material 7 to the retention mechanism 6, the double-station conveying equipment 2 also includes a lifting mechanism, which is arranged on both sides of the first conveying mechanism 21. The lifting mechanism includes a fixed part, a first movable structure, a second movable structure and a lifting frame. The first movable structure is suitable for making the second movable structure and the lifting frame rotate around the fixed part, and the second movable structure is suitable for moving the lifting frame up and down; the fixed part is a cylindrical mounting column, and the first movable structure is a rotating kit that is sleeved on the top position of the mounting column and can rotate; the second movable structure includes a frame body fixedly mounted with the rotating kit, and the frame body is formed with two upper and lower hinged mounting parts, the upper hinged mounting part is installed with a connecting rod, and the lower hinged mounting part is installed with a cylinder, the piston rod of the cylinder is hingedly connected to the bottom of the connecting rod, when the cylinder extends the piston rod, the end of the connecting rod brings the lifting frame up, and when the cylinder contracts the piston rod, the end of the connecting rod brings the lifting frame down; the lifting mechanism is suitable for stacking the excess materials 7 produced by the laser cutting equipment 1 on the retention mechanism 6.

[0049] The second movable structure can allow the hanging frame to move up and down. When the hanging frame moves down, its height is reduced, and it is more convenient for workers or machines to transfer the material 7 to the hanging frame. However, the weight of the material 7 is large when it is stacked, so the first movable structure can allow the second movable structure and the hanging frame to rotate. After the material 7 is placed on the hanging frame, the second movable structure allows the hanging frame to rise, and then the first movable structure is rotated to realize the lifting and transfer of the material 7. Even if manual operation is used, the labor intensity can be greatly reduced.

[0050] Reference Figures 4 to 6 The inner circle processing equipment 3 of this embodiment includes a conveying mechanism and a stamping mechanism 31. The middle part of the conveying mechanism is open to form a stamping station, and the stamping mechanism 31 is arranged on the stamping station. A feeding mechanism 32 is arranged above the conveying mechanism. One feeding mechanism 32 is arranged on both sides of the stamping mechanism 31. The feeding mechanism 32 on the inlet side is suitable for clamping the material 7 from one side of the conveying mechanism to the stamping mechanism 31. After the stamping is completed, the feeding mechanism 32 on the outlet side is suitable for clamping the material 7 from the stamping mechanism 31 to the other side of the conveying mechanism; a positioning component is arranged on the outside of the stamping mechanism 31, and an induction component is arranged between the positioning component and the feeding mechanism 32. When the feeding mechanism 32 on the inlet side runs to its maximum stroke, the induction component is automatically triggered so that the positioning component pushes the material 7 to the stamping position.

[0051] By setting the sensing component, when the material 7 reaches the appropriate position, the positioning component can be automatically triggered to position the material 7 to the appropriate position for stamping. In the existing stamping equipment, the production line type production usually adopts the method of equal-interval feeding to achieve continuous stamping, that is, the interval of each feeding is the same, so that the stamping mechanism 31 only needs to perform simple reciprocating stamping to complete the periodic production. However, in the case of larger parts such as the end plate in this embodiment or some parts with complex processes, it is difficult to achieve equal-interval feeding every time due to the different production and processing procedures of the parts, so the equal-interval feeding is not applicable. In this embodiment, the sensing component is set, and the sensing component is triggered by a mechanical condition, so that when the feeding mechanism 32, the positioning component and the stamping mechanism 31 are used together, a stable and accurate coordination effect can be achieved. For example, the use of a visual camera can also achieve the joint use of the three, but its stability and accuracy are not as good as mechanical triggering. Of course, the sensing component of the present application actually needs to be operated by means of electronic control in the future, but it has good accuracy and stability in the key issue of how to identify the material 7 in the appropriate position and automatically position the positioning component.

[0052] The positioning assembly includes a fixed limiting portion 35 arranged on the front side of the stamping mechanism 31 and a pushing portion 34 arranged at the rear of the stamping mechanism 31. When the feeding mechanism 32 transfers the material 7 to the stamping station, the sensing assembly is triggered so that the pushing portion pushes the material 7 and abuts against the fixed limiting portion 35 to position the material 7. The sensing assembly includes an elastic member and a pressure sensor arranged on the feeding mechanism 32. When the feeding mechanism 32 clamps the material 7, the elastic member is elastically compressed. When the feeding mechanism 32 releases the material 7, the elastic member is reset, the pressure sensor recognizes the pressure change, and starts the pushing portion 34. The elastic member It includes a trigger rod and a spring. When the material 7 is clamped, the trigger rod moves to avoid or shrinks and the spring shrinks. When the material 7 is released, the spring and the trigger rod reset. The pressure sensor and the spring are connected. The feeding mechanism 32 includes a transverse movement component, a lifting component and a feeding part 33. The lifting component is arranged on the transverse movement component as a whole, and the feeding part 33 is arranged on the lifting component. The feeding part 33 is provided with an electromagnet. When the feeding part 33 approaches the material 7, the material 7 is directly adsorbed, and the elastic part is compressed in the process. Until the feeding part 33 and the material 7 reach the top of the stamping mechanism 31, the feeding part 33 releases the material 7, and the elastic part resets to trigger the pressure sensor recognition.

[0053] It can be understood that the positioning component is triggered by the compression of the spring and then transferred to the sensing component for triggering. This triggering process does not require additional identification of the loading status, and the triggering condition is the change of the mechanical structure, so it is more stable and accurate.

[0054] Reference Figure 7 and Figure 8The flattening device 4 of this embodiment includes a conveying mechanism, a flattening mechanism and a feeding mechanism 41. The feeding mechanism 41 includes a fixing component, a transverse movement component and a correction component 42. The conveying mechanism is suitable for conveying the material 7 to the entrance of the flattening mechanism. The feeding mechanism 41 is suitable for grabbing the material 7 through the fixing component and continuing to push the material 7 to the flattening position of the flattening mechanism through the transverse movement component. The correction component 42 includes a correction part 43 for unidirectional feeding in the feeding direction. At least two correction parts 43 are arranged at intervals. The correction parts 43 are arranged at the material When the material 7 passes by in the feeding direction, it avoids to allow the material 7 to pass; when the material 7 acts on the correction part 43 in the opposite direction of the feeding direction, the correction part 43 does not avoid, and the feeding mechanism continues to run in the feeding direction to move the material 7 and leave the leveling mechanism; the correction part 43 is rotatably arranged, and a pair of hinge shafts are arranged on the top of the correction part 43. The correction part 43 is rotatably installed by the hinge shafts, and 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 rotation of the correction part 43 in the feeding direction.

[0055] 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 41 of this embodiment grabs the material 7 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, to prevent the fixed component and the leveling mechanism from interfering; after the leveling is completed, the fixed component grabs the next material 7, and then the transverse component drives the second material 7 to load. During the process, the correction part 43 on the outlet side acts on the previous material 7. Since the material 7 is a one-way material, when the second material 7 is loaded, the first material 7 is also unloaded, thus completing the entire loading and unloading process.

[0056] The role of the correction part 43 in the whole process is one-way material feeding. In the feeding direction, the electromagnet 44 can be used to adsorb and load the material. In this loading process, when the correction part 43 contacts the material 7 that was flattened last time, since the correction part 43 is restricted from rotating by the limiting plate, when the correction part 43 moves in the feeding direction, the material 7 that was flattened last time will be automatically pushed out of the material, thus completing the loading and unloading process.

[0057] Reference Figures 9 to 12The groove processing equipment 5 of this embodiment includes a conveying mechanism, a pushing mechanism, a first slicer mechanism 51, a second slicer mechanism 52 and a feeding mechanism. The first slicer mechanism and the second slicer mechanism 52 are arranged perpendicular to each other, and the ends of the slicer tracks of the first slicer mechanism and the second slicer mechanism 52 are connected to form an L-shaped configuration. When the pushing mechanism pushes the material 7 located at the first slicer mechanism 51 to move to the maximum stroke, the material 7 does not reach the slicer track of the second slicer mechanism 52. After a number of materials 7 processed by the first slicer mechanism 51 are arranged in sequence, the next material 7 processed by the first slicer mechanism 51 is The material 7 pushes the material 7 located at the front into the planing track of the second planing mechanism 52, and then the pushing mechanism pushes the material 7 to be processed by the second planing mechanism 52, and finally it is transferred to the unloading mechanism for unloading; the first planing mechanism 51 and the second planing mechanism 52 both plane the material 7 to form a groove through multiple planing, and the depth of the multiple planing is the same or decreases successively. The first planing mechanism 51 and the second planing mechanism 52 are respectively provided with material guide tracks at their two planing tracks, and the end of the material guide track at the first planing mechanism 51 extends to the initial end of the material guide track of the second planing mechanism 52.

[0058] The first planing mechanism 51 and the second planing mechanism 52 each include two symmetrically arranged planing tool groups, which are respectively used to plane the opposite sides of the material 7; the same planing tool group includes a plurality of planing blades 53 arranged at intervals, and a planing interval is formed between two adjacent planing blades 53, and the depths of all planing blades 53 of the same planing tool group increase successively along the planing direction to the set planing length; the planing tool groups on both sides are hingedly installed and can be translated as a whole, and the planing tool groups are provided with corresponding fixed structures, and the planing angle is changed by rotating the planing tool group during installation; the multiple planing intervals generated between the multiple planing blades 53 in the same planing tool group increase successively along the planing direction; the increase in the planing depth direction of the multiple planing blades 53 in the same planing tool group decreases successively along the planing direction.

[0059] This embodiment uses a planing device to perform the planing operation. Unlike common planing equipment, this equipment is usually used for production on an assembly line, so the planing equipment is usually located in a relatively fixed area and position. In addition, in order to ensure that the same batch of products are relatively consistent after processing, the planing equipment is usually adjusted to a set position before use and will not move again, which limits its use to a certain extent. Obviously, the planed part at the corner is usually not too thin, because when the cutting is thin, the formed groove has little effect on welding. For this reason, in this embodiment, the first planing mechanism 51 and the second planing mechanism 52 are both provided to plan the material 7 out of the groove through multiple planing, and the depth of the multiple planing is the same or decreases successively. The first planing mechanism 51 and the second planing mechanism 52 are respectively formed with material guide tracks at their two planing tracks, and the end of the material guide track at the first planing mechanism 51 extends to the initial end of the material guide track of the second planing mechanism 52 to form an L-shaped configuration.

[0060] like Fig.11 As shown, there is a dotted line below the planing blade 53, which reflects the height of the bottoms of three planing blades 53 arranged at intervals among different planing blades 53. Fig.11 From left to right in the figure is the planing direction of the material 7. It can be seen that the planing blade 53 on the far left protrudes the least, and the corresponding planing depth is smaller when it is in contact with the material 7. The planing blade 53 in the middle is slightly downward, so the corresponding planing depth of the material 7 increases a little. The planing blade 53 on the right has the largest depth, so the corresponding planing depth continues to increase. The corresponding cutting diagram of the material 7 can be referred to Fig.12 , Figure 7 In the figure, d1 is a schematic diagram of the cutting depth of the leftmost planing blade 53, d2 is a schematic diagram of the cutting depth of the middle planing blade 53, and d3 is a schematic diagram of the cutting depth of the right planing blade 53. If the planing blade 53 directly planing at the depth of d3, the blade will be easily damaged due to the greater depth and the reaction to the blade. However, after multiple planing, the damage to the blade can be effectively reduced.

[0061] On the other hand, the present application proposes a square flange flexible processing control method, based on the above-mentioned square flange flexible processing production line, comprising the following steps:

[0062] a. Cutting the prototype of the material 7: The material 7 is quickly cut into the shape of the end plate by the laser cutting device 1 to form the prototype of the material 7.

[0063] b. Diversion and transfer of materials 7: The cut prototypes of materials 7 are conveyed through two or any one of the stations of the double-station conveying equipment 2 and transferred to the corresponding production line. The cut materials 7 that exceed the rate of subsequent process are stored through the retention mechanism 6, and after the normal production line is processed, they are re-transferred into the production line for subsequent processing through the transfer mechanism 8 with an extended transfer stroke.

[0064] c. Inner circle processing of the material 7: In the corresponding production line, the inner circle processing equipment 3 punches and cuts the material 7 to form an inner circle, and transfers the processed material 7 to the flattening equipment 4.

[0065] d. Smoothing the surface of the material 7: When the material 7 reaches the leveling device 4, the leveling device 4 will grind and level the surface of the material 7 with the inner circle punched out to make the surface of the material 7 smooth, and finally continue to transfer the material 7 to the groove processing equipment 5. The processing efficiency of the leveling device 4 is slower than that of other processes. Part of the material 7 is stored through the retention mechanism 6, and after the normal production line is processed, it is re-transferred to the production line for subsequent processing through the transfer mechanism 8 with an extended transfer stroke.

[0066] e. Bevel processing of the material 7: The bevel processing equipment 5 planes the corners of the material 7 to form a bevel shape. The planing is performed from shallow to deep and multiple planing is performed to finally complete the processing of the end plate material 7.

[0067] Through the double-station conveying equipment 2, the present application can realize arbitrary control of the material 7 to the corresponding production line for production; since the cutting process is faster and the flattening process of the flattening mechanism is slower, a retention mechanism 6 is set at the double-station conveying equipment 2 and the flattening mechanism, which can stack the materials 7 that cannot be processed in time, thereby ensuring the effectiveness efficiency.

[0068] 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.
