Description

Technical Field

[0001] The invention relates to the technical field of pipe support presses, in particular to a press for producing metal pipe supports. Background Art

[0002] Metal pipe supports are devices used to support and fix pipelines. They are widely used in pipeline systems, especially in industrial fields such as oil, gas, electricity, and chemical industries. Their main functions are to bear the weight of the pipeline, limit the displacement of the pipeline, and ensure the safety and stability of the pipeline in various working environments.

[0003] For example, the patent with the national authorized patent announcement number CN213137896U discloses a new type of servo forming press, which belongs to the technical field of mechanical presses. A pinion is installed on the output shaft of the low-speed, high-torque servo motor, and the pinion meshes with the eccentric gear. The eccentric gear is installed on the fuselage through the fuselage bushing. The eccentric gear is rotatably connected to the pin shaft through the pin bearing bushing. The pin shaft is fixedly connected to the rocker arm. The rocker arm is rotatably connected to the mandrel through the mandrel bearing bushing. The mandrel is fixedly connected to the connecting rod, and the slider is fixedly connected to the connecting rod. The new servo forming press adopts a bilateral gear transmission structure with a symmetrical arrangement, which is more conducive to resisting off-center loads during multi-station processing or large-piece forming, thereby ensuring processing accuracy; it adopts a dual servo motor structure. When the slider is subjected to non-uniform loads, the vertical accuracy of the slider operation can be ensured by the difference in the output torque of the two servo motors, thereby ensuring the quality of the processed parts.

[0004] However, the new servo forming press mentioned above does not have the function of automatic unloading and loading during the process of pressing and forming the workpiece. After each pressing is completed, it needs to be manually unloaded and then loaded. This will greatly increase the processing cycle of a single workpiece and reduce the effective working time of the equipment, which is not conducive to improving production efficiency.

The pipe support pressed into the die groove of the lower die can be pushed into the receiving plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the design of the connecting frame, the lower die, the connecting plate, the guide frame, the discharge frame, the pressing and forming mechanism and the loading and unloading mechanism, when the pipe sleeve is pressed and formed, the staff can stack the metal plates in the two sets of discharge frames, and then start the loading and unloading mechanism and the pressing and forming mechanism in turn, so that the loading and unloading mechanism can slide the metal plates at the lower ends of the two sets of discharge frames into the guide frame, and the guide frame extends to the upper surface of the lower die and an L-shaped baffle is provided at the end, so that the metal plates pushed by the loading and unloading mechanism in the guide frame can touch one end of the L-shaped baffle when sliding to the end, so as to ensure that the metal plates can be accurately pushed to the upper surface of the lower die and flush with the pressing and forming mechanism, and the pipe support originally pressed and formed in the die groove of the lower die will also be pushed out from it by the loading and unloading mechanism and fall into the receiving plate, and then the loading and unloading mechanism can be driven to reset and slide out of the guide frame, so that the stacked metal plates in the discharge frame can fall into the guide frame again, and then the started pressing and forming mechanism will be pushed to slide vertically down in the connecting frame. The metal plate is pressed into the die groove in the lower die to form a pipe support, and then the loading and unloading mechanism can be started again to push the metal plate in the discharge frame into the upper surface of the lower die again, and at the same time, the pipe support in the die groove of the lower die is pushed out for the pressing and forming mechanism to press the metal plate into the die groove of the lower die again, so that the metal plate can be continuously pressed into the pipe support by reciprocating, and the pressing and forming mechanism will be pulled together in the process of being driven to slide down in the connecting frame, so that the spring can apply a pulling force to the pressing and forming mechanism, and the pulling force of the spring has a buffering effect on the pressing and forming mechanism, and when the pressing and forming mechanism quickly slides down to press the metal plate, the spring can absorb part of the impact force, reducing the rigid impact between the equipment, and in the whole process, by successively starting the loading and unloading mechanism and the pressing and forming mechanism, a series of operations such as automatic pushing of metal plates, automatic unloading of pipe supports and automatic pressing of new pipe supports can be realized, which greatly reduces the time of manual intervention, improves the degree of automation of production, and thus helps to improve the overall production efficiency.

[0019] 2. Through the design of the first motor, eccentric shaft, gear ring, connecting arm, connecting block, upper mold and guide rod, after the metal plate is pushed to the upper surface of the lower mold, the first motor can be started to drive one group of eccentric shafts to rotate, so that the eccentric shaft can be meshed with the gear ring on the outer surface to drive the other group of eccentric shafts to rotate relatively, so that the two groups of eccentric shafts can drive the connecting arm to push and pull reciprocatingly, and the connecting block can slide vertically in the guide strip through the guide rods at both ends, so that the connecting block can drive the upper mold on the lower surface to press the metal plate into the mold groove of the lower mold to form a pipe support. The design of the entire structure enables the upper mold to smoothly press the metal plate into the mold groove of the lower mold. The coordinated work of the eccentric shaft, connecting arm, connecting block and other components, as well as the constraint of the movement by the guide rod and the guide strip, jointly ensure the stability of the pressing process. The stable pressing process helps to produce pipe supports with uniform quality and that meet the standards, and reduce waste caused by unstable pressing process.

[0020] 3. Through the design of the second motor, threaded rod, connecting rod, push plate and unloading push plate, the metal plate is placed in the two sets of discharge frames, the second motor can be started to drive the forward and reverse threads of the threaded rod to drive the two sets of connecting rods to slide outward or inward synchronously, so that the two sets of connecting rods can respectively drive the push plates to slide into the guide frame to push the metal plates at the lower ends of the two sets of discharge frames into the guide frame, and the guide frame extends to the upper surface of the lower die and an L-shaped baffle is provided at the end, so that the metal plate can be pushed by the push plate to slide in the guide frame to the end, and can touch one end of the L-shaped baffle and be on the upper surface of the lower die at the same time, and the connecting rod drives the push plate to slide into the guide frame. The process will drive the unloading push plate on the lower surface to slide into the die groove of the lower die. The tube support formed in the die groove of the lower die can be pushed out, and the tube support formed can be pushed out from it together with the metal plate when it is pushed to the upper surface of the lower die. Then the second motor can be started again to drive the threaded rod to reverse, so that the two sets of connecting rods can be pulled toward the center synchronously, so that the pushing plate can be pulled out of the guide frame, and the stacked metal plates in the discharge frame can fall into the guide frame again for the pushing plate to push the metal plate to the upper end of the lower die again. During the whole process, a series of operations such as pushing the metal plate, unloading and resetting can be quickly realized by starting the forward and reverse rotation of the second motor. This fast cycle operation enables the equipment to complete multiple pressing tasks in a relatively short time, thereby greatly improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 9 , this embodiment provides the following technical solutions:

[0033] like Figure 1-Figure 2 As shown, a press machine for producing metal pipe supports comprises: two groups of connecting frames 1, a connecting plate 106 is fixedly installed between the two groups of connecting frames 1, guide frames 102 are fixedly installed at both ends of the upper surface of the connecting plate 106, the two groups of guide frames 102 are arranged opposite to each other, and discharge frames 103 are extended and installed on the upper surfaces of the two groups of guide frames 102, and metal plates are stacked in the discharge frames 103, so that the metal plate at the lower end of the discharge frame 103 slides in the guide frame 102 and can be pushed into the lower die 105 by the loading and unloading mechanism 3, The loading and unloading mechanism 3 is fixedly installed on the lower surface of the connecting plate 106, and the lower mold 105 is fixedly installed in the connecting frame 1. The two groups of lower molds 105 are located at both ends of the connecting plate 106 and are flush with the connecting plate 106. The upper surfaces of the two groups of connecting frames 1 are fixedly installed with top covers 101, and a pressing and forming mechanism 2 is rotatably installed in the top cover 101. The pressing and forming mechanism 2 is flush with the lower mold 105, so that the pressing and forming mechanism 2 can press the metal plate placed on the upper surface of the lower mold 105 into the mold groove of the lower mold 105 to form a pipe support.

[0034] Among them, the guide frame 102 extends to the upper surface of the lower mold 105 and an L-shaped baffle 109 is fixedly installed at the end, so that the metal plate can touch one end of the L-shaped baffle 109 when it is pushed by the loading and unloading mechanism 3 in the guide frame 102 and slides to the end, thereby ensuring that the metal plate can be accurately pushed to the upper surface of the lower mold 105 and flush with the pressing and forming mechanism 2. A receiving plate 104 is fixedly installed at one end of the connecting frame 1, and the receiving plate 104 is located at the lower end of the lower mold 105, so that the pipe support pressed and formed in the lower mold 105 can be pushed out from it by the loading and unloading mechanism 3 and fall into the receiving plate 104.

[0035] Through the design of the connecting frame 1, the lower die 105, the connecting plate 106, the guide frame 102, the discharge frame 103, the pressing and forming mechanism 2 and the loading and unloading mechanism 3, when the pipe sleeve is pressed and formed, the staff can place the metal plates in the two sets of discharge frames 103, and then start the loading and unloading mechanism 3 and the pressing and forming mechanism 2 in turn, so that the loading and unloading mechanism 3 can slide the metal plates at the lower ends of the two sets of discharge frames 103 into the guide frame 102, and the guide frame 102 extends to the upper surface of the lower die 105 and is provided with an L-shaped baffle 109 at the end, so that the metal plates can be loaded and unloaded by the loading and unloading mechanism 3. When the metal plate is pushed and slid to the end in the guide frame 102, it can touch one end of the L-shaped baffle plate 109, thereby ensuring that the metal plate can be accurately pushed to the upper surface of the lower die 105 and flush with the pressing and forming mechanism 2, and the tube bracket originally pressed and formed in the die groove of the lower die 105 will also be pushed out from it by the loading and unloading mechanism 3 and fall into the receiving plate 104, and then the loading and unloading mechanism 3 can be driven to reset and slide out of the guide frame 102, so that the stacked metal plates in the discharge frame 103 can fall into the guide frame 102 again, and then the activated pressing and forming mechanism 2 will The metal plate is pushed down vertically in the connecting frame 1 to press the metal plate into the die groove in the lower die 105 to form a tube support. Then, the loading and unloading mechanism 3 can be started again to push the metal plate in the discharge frame 103 into the upper surface of the lower die 105 again, and at the same time, the tube support in the die groove of the lower die 105 is pushed out for the pressing and forming mechanism 2 to press the metal plate into the die groove of the lower die 105 again. In this way, the metal plate can be continuously pressed into the tube support by reciprocating, and the pressing and forming mechanism 2 is driven to slide down in the connecting frame 1, and the spring 107 is pulled together, so that the spring 107 can press the forming Mechanism 2 applies a pulling force, and the pulling force of spring 107 has a buffering effect on the pressing and forming mechanism 2. When the pressing and forming mechanism 2 slides down quickly to press the metal plate, the spring 107 can absorb part of the impact force, reducing the rigid impact between the equipment. In the whole process, by successively starting the loading and unloading mechanism 3 and the pressing and forming mechanism 2, a series of operations such as automatic pushing of the metal plate, automatic unloading of the pipe support and automatic pressing of the new pipe support can be realized. This greatly reduces the time of manual intervention, improves the degree of automation of production, and thus helps to improve the overall production efficiency.

[0036] like Figure 3-Figure 6 As shown, the pressing and forming mechanism 2 includes two groups of eccentric shafts 202, which are rotatably installed in the top cover 101 and the rotating shafts at both ends are rotated through the top cover 101 and rotated in the bearing seat 204, and the bearing seat 204 is fixedly installed at both ends of the top cover 101. Connecting arms 205 are rotatably installed in the two groups of eccentric shafts 202, and the other ends of the two groups of connecting arms 205 are rotatably installed on the outer surface of the rotating rod 210. A connecting block 206 is fixedly installed on the lower surface of the rotating rod 210, and a threaded column 211 is fixedly installed on the lower surface of the connecting block 206. An upper mold 207 is inserted on the outer surface of the threaded column 211, and a nut is threadedly installed on the outer surface of the threaded column 211, so that the nut is spirally pressed against the lower surface inside the upper mold 207.

[0037] Among them, guide rods 208 are fixedly installed at both ends of the connecting block 206, and the guide rods 208 are slidably installed in the guide strips 108. The guide strips 108 are fixedly installed at both ends of the connecting frame 1, so that when the connecting block 206 is pushed by the connecting arm 205, it can slide vertically in the guide strips 108 through the guide rods 208 on both sides. Hook rings 209 are fixedly installed at both ends of the upper surface of the connecting block 206, and the hook rings 209 are fixedly connected to the spring 107. The other end of the spring 107 is fixedly connected to one end of the connecting frame 1.

[0038] One set of eccentric shafts 202 is fixedly connected to the output shaft of the first motor 201, and the first motor 201 is fixedly installed at one end of the top cover 101. A gear ring 203 is fixedly installed in the middle part of the outer surface of the two sets of eccentric shafts 202. The two sets of gear rings 203 are meshed with each other, so that when one set of eccentric shafts 202 is driven to rotate, the gear ring 203 meshes with the other set of eccentric shafts 202 to rotate relatively together, and the two sets of eccentric shafts 202 can drive the connecting arm 205 to push and pull the connecting block 206 reciprocatingly.

[0039] Through the design of the first motor 201, the eccentric shaft 202, the gear ring 203, the connecting arm 205, the connecting block 206, the upper mold 207 and the guide rod 208, after the metal plate is pushed to the upper surface of the lower mold 105, the first motor 201 can be started to drive one set of eccentric shafts 202 to rotate, so that the eccentric shaft 202 can be meshed with the gear ring 203 on the outer surface to drive the other set of eccentric shafts 202 to rotate relatively together, so that the two sets of eccentric shafts 202 can drive the connecting arm 205 to push and pull the connecting block 206 reciprocatingly through the guide rods 208 at both ends to hang down in the guide bar 108. Straight sliding can enable the connecting block 206 to drive the upper mold 207 on the lower surface to press the metal plate into the mold groove of the lower mold 105 to form a pipe support. The design of the entire structure enables the upper mold 207 to smoothly press the metal plate into the mold groove of the lower mold 105. The coordinated work of the eccentric shaft 202, the connecting arm 205, the connecting block 206 and other components, and the constraint of the movement by the guide rod 208 and the guide bar 108 together ensure the stability of the pressing process. The stable pressing process is conducive to the production of pipe supports with uniform quality and that meet the standards, and reduces the waste generated by the unstable pressing process.

[0040] In order to make the technical solution of the press machine for producing metal tube supports more perfect, the relevant equations of the pressing and forming mechanism are introduced in this embodiment, and the motion relationship between the eccentric shaft and the connecting arm is as follows:

[0041] Assuming that the radius of the eccentric shaft is r, the rotational angular velocity of the eccentric shaft 202 is w, the length of the connecting arm 205 is L, and the angle between the connecting arm and the eccentric shaft is θ, the vertical displacement y of the connecting block 206 can be described by the following equation:

[0042]

[0043] Example: Given that the radius of the eccentric shaft 202 is r = 0.05 m, the length of the connecting arm 205 is L = 0.2 m, the rotational angular velocity of the eccentric shaft 202 is w = 10πrad / s, and the initial angle θ = π / 4, at t = 0.1 s, calculate the vertical displacement y of the connecting block 206.

[0044]

[0045] y≈0.162m.

[0046] This equation can accurately describe the vertical displacement of the connecting block 206, which helps to accurately analyze and optimize the movement of the pressing and forming mechanism during the design stage, ensuring that the upper die 207 can accurately press the metal plate into the die groove of the lower die 105, thereby improving the pressing accuracy of the tube support.

[0047] like Figure 7-Figure 9As shown, the loading and unloading mechanism 3 includes a U-shaped frame 302, which is fixedly installed between the two groups of connecting frames 1. A threaded rod 303 is rotatably installed in the U-shaped frame 302. The threads at both ends of the threaded rod 303 are respectively forward and reverse. The outer surfaces of the forward and reverse threads of the threaded rod 303 are threadedly installed with connecting rods 304. The other ends of the two groups of connecting rods 304 are fixedly installed with a pushing plate 305. The pushing plate 305 slides from the guide opening 110 to the upper surface of the connecting plate 106 and is flush with the height of the guide frame 102. The guide opening 110 is opened on the upper surface of the connecting plate 106, so that the two groups of connecting rods 304 can be synchronously driven by the threaded rod 303 to slide outward or inward, so that the two groups of connecting rods 304 can drive the pushing plate 305 to push the connecting rod 306. The plate 305 slides into the guide frame 102 to push the metal plate out therefrom. A second motor 301 is fixedly installed at one end of the C-shaped frame 302. The output shaft of the second motor 301 passes through the C-shaped frame 302 and is fixedly connected to the threaded rod 303. A sliding column 307 is fixedly installed in the C-shaped frame 302. The sliding column 307 slides out from the connecting rod 304. A discharge push plate 306 is fixedly installed on the lower surface of the connecting rod 304. In this way, the connecting rod 304 drives the push plate 305 to slide into the guide frame 102, and at the same time drives the discharge push plate 306 to slide into the die groove of the lower die 105, so that in the process of pushing the metal plate into the lower die 105, the pipe support in the die groove of the lower die 105 can be pushed into the receiving plate 104.

[0048] The second motor 301, the threaded rod 303, the connecting rod 304, the pushing plate 305 and the unloading pushing plate 306 are designed to stack the metal plates in the two sets of unloading frames 103 and start the second motor 301 to drive the forward and reverse threads of the threaded rod 303 to transmit the two sets of connecting rods 304 to slide synchronously outward or inward, so that the two sets of connecting rods 304 can respectively drive the pushing plates 305 to slide into the guide frame 102 to push the metal plates at the lower ends of the two sets of unloading frames 103 into the guide frame 102, and the guide frame 102 extends to the upper surface of the lower mold 105 and an L-shaped baffle 109 is provided at the end thereof, so that the metal plates can be pushed by the pushing plates 305 to slide in the guide frame 102 to the end thereof and can touch one end of the L-shaped baffle 109 and be at the upper surface of the lower mold 105 at the same time, and the connecting rod 304 drives the pushing plates 305 to slide into the guide frame 102, which will drive the unloading The material pushing plate 306 is slidably inserted into the die groove of the lower die 105 to push out the tube support formed in the die groove of the lower die 105, thereby realizing that the metal plate can be pushed to the upper surface of the lower die 105 and the pressed tube support can be pushed out therefrom at the same time, and then the second motor 301 can be started again to drive the threaded rod 303 to reverse to realize the synchronous pulling of the two sets of connecting rods 304 toward the center, so that the pushing plate 305 can be pulled out of the guide frame 102, and the stacked metal plates in the material discharge frame 103 can fall into the guide frame 102 again for the pushing plate 305 to push the metal plate to the upper end of the lower die 105 again. During the whole process, by starting the forward and reverse rotation of the second motor 301, a series of operations such as pushing the metal plate, unloading and resetting can be quickly realized. This fast cycle operation enables the equipment to complete multiple pressing tasks in a relatively short time, greatly improving the production efficiency.

[0049] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when the pipe sleeve is pressed and formed, the staff can place the metal plate in the two sets of discharge frames 103, and then start the second motor 301 and the first motor 201 successively, so that the second motor 301 can drive the forward and reverse threads of the threaded rod 303 to drive the two sets of connecting rods 304 to slide outward or inward synchronously, so that the two sets of connecting rods 304 can respectively drive the pushing plate 305 to slide into the guide frame 102 to slide the metal plate at the bottom of the two sets of discharge frames 103 into the guide frame 102, and the guide frame 102 The upper surface of the lower die 105 is extended and an L-shaped baffle 109 is provided at the end, so that the metal plate can be pushed by the pushing plate 305 to slide in the guide frame 102 to the end, and can touch one end of the L-shaped baffle 109 and be at the upper surface of the lower die 105 at the same time, and the connecting rod 304 drives the pushing plate 305 to slide into the guide frame 102. In the process, the unloading push plate 306 on the lower surface is driven to slide into the die groove of the lower die 105, so as to push out the tube support pressed in the die groove of the lower die 105, thereby realizing that the metal plate can be pushed to the upper surface of the lower die 105 at the same time. The pressed tube support is pushed out, and then the second motor 301 can be started again to drive the threaded rod 303 to reverse to pull the two groups of connecting rods 304 toward the center synchronously, so that the pushing plate 305 can be pulled out of the guide frame 102, so that the stacked metal plates in the discharge frame 103 can fall into the guide frame 102 again, and then the first motor 201 can be started to drive one group of eccentric shafts 202 to rotate, so that the eccentric shaft 202 can mesh with the gear ring 203 on the outer surface to drive the other group of eccentric shafts 202 to rotate relatively, so that the two groups of eccentric shafts can rotate together. The spindle 202 together drives the connecting arm 205 to push and pull the connecting block 206 back and forth through the guide rods 208 at both ends to slide vertically in the guide bar 108, so that the connecting block 206 can drive the upper mold 207 on the lower surface to press the metal plate into the mold groove of the lower mold 105 to form a pipe support. Then, the second motor 301 can be started again to push the metal plate in the discharge frame 103 into the upper surface of the lower mold 105 again, and at the same time, the pipe support in the mold groove of the lower mold 105 is pushed out for the upper mold 207 to press the metal plate into the mold groove of the lower mold 105 again, so that the metal plate can be continuously pressed into the pipe support by reciprocating.

[0050] In summary: the press machine can automatically load and unload materials during the process of pressing and forming the pipe support, which greatly reduces the time of manual intervention, improves the degree of automation of production, and thus helps to improve overall production efficiency.
