Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, and more specifically, it relates to a pipe fitting turning device. Background Technique

[0002] The processing and production of pipe fittings usually include steps such as material storage, turning, and feeding. Bundled materials are stored on a material rack, and then a certain amount of materials are grabbed by a turning device and placed on a feeding device. Finally, the materials are fed onto the production line automatically or manually by the feeding device. For example, in Chinese Patent Publication No. CN 219189488 U, announced on June 16, 2023, the invention is named an automatic feeding device for a pipe cutting machine. In this application, a lever mechanism is disclosed. By rotating a rotating shaft to drive a movable hook, the movable hook then toggles the pipe fitting, pushing the pipe fitting to be stored on a third support. After that, it is turned by a turning claw. The cooperation of the lever mechanism with each support ensures the accuracy of pipe fitting feeding, and there will be no deviation in the number of pipe fittings cut.

[0003] However, the turning effect of the movable hook on the pipe fitting in this lever mechanism is poor, and it may also scratch the pipe fitting. In addition, after the pipe fitting is toggled, it will be lifted first and then dropped onto the third support for storage. If there are already pipe fittings in the third support, the pipe fittings may collide and deform with each other. Moreover, after the pipe fitting falls into the third support, it still needs to be aligned by a horizontal push plate and then turned, resulting in low feeding work efficiency. Content of the Utility Model

[0004] The utility model overcomes the deficiency of the poor turning effect of the lever mechanism in the prior art, and provides a pipe fitting turning device, which has a more stable and reliable turning process for pipe fittings, will not damage the pipe fittings, and can also automatically send the pipe fittings to a sawing machine for processing.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: a pipe fitting turning device, including a turning plate assembly, the turning plate assembly includes a lever and a power assembly, and the power assembly is hinged to the lever; the turning plate assembly also includes a turning seat bottom plate and a turning seat fixed on the turning seat bottom plate, and the lever is hinged to the turning seat.

[0006] The utility model is provided with a turning plate assembly. The turning plate assembly is provided with a lever and a power assembly hinged to the lever. A turning seat and a turning seat bottom plate are also provided, and the lever is also hinged to the turning seat. The power assembly provides power to push the lever to rotate, so that the lever is lifted up, thereby completing the turning; the contact area between the lever and the pipe fitting is large, the turning is reliable, and at the same time, the power provided by the power assembly is stable, which can avoid damage to the pipe fitting caused by collision.

[0007] Preferably, the power assembly is fixed on the base of the tipping seat. One end of the power assembly is hinged to the lever, and the other end is fixed to the base of the tipping seat, which can provide power more stably and push the lever to turn the material.

[0008] Preferably, it further includes a material rack, on which a number of roller assemblies are provided. The roller assemblies include rollers and sprockets. The rollers and sprockets in the roller assemblies are installed on the same rotating shaft, and all the sprockets in the roller assemblies are connected by the same chain.

[0009] All the sprockets in the roller assemblies are connected by the same chain, which can drive all the sprockets to rotate simultaneously, and then drive all the rollers to rotate. When the pipe fittings are placed on the material rack, the rotation of the roller assemblies can automatically transport the pipe fittings to the sawing machine for processing.

[0010] Preferably, a material pushing inclined surface is provided on the lever, and the end of the material pushing inclined surface far from the material rack is higher than the end close to the material rack.

[0011] When the material pushing inclined surface contacts the pipe fittings and the power assembly pushes the lever to rotate, the lever is lifted, so that the material pushing inclined surface will lift the pipe fittings. The pipe fittings will automatically slide to one end of the material rack on the material pushing inclined surface to complete the turning of the material.

[0012] Preferably, it further includes a bracket, and the tipping plate assembly is fixed on the bracket through the base plate of the tipping seat.

[0013] The bracket is used to place the pipe fittings to be processed. The tipping plate assembly is fixed on the bracket, which is convenient for the tipping plate assembly to turn the material.

[0014] Preferably, an inclined rod is provided above the bracket, and the end of the inclined rod far from the material rack is higher than the end close to the material rack.

[0015] The rod above the bracket is set as an inclined rod, and the end far from the material rack is high and the end close to the material rack is low, which can make the pipe fittings to be processed automatically slide to the end close to the material rack and be arranged neatly when placed on the bracket.

[0016] Preferably, a baffle is provided at the end of the inclined rod close to the material rack. The baffle is used to block the pipe fittings to be processed that slide to the end of the inclined rod close to the material rack, which can ensure that the pipe fittings will not slide onto the material rack. When processing is required, the lever can lift the pipe fittings to a position higher than the baffle to realize turning of the material.

[0017] Preferably, a number of soft cushion blocks are also provided on the material rack at equal intervals. The soft cushion blocks can further prevent the pipe fittings from colliding with the material rack and being damaged.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] (1) The setting of the turnover plate assembly can increase the contact area between the lever and the pipe fitting during turnover, making the turnover process more reliable and stable, and enabling accurate and automatic turnover of the pipe fitting.

[0020] (2) The setting of the roller assembly on the material rack enables the pipe fitting to be directly transported to the sawing machine for processing after reaching the material rack, realizing automatic feeding.

[0021] (3) The setting of the inclined rod and the baffle on the bracket enables the pipe fittings to be automatically arranged neatly on the bracket, facilitating the turnover process. Description of the Drawings

[0032] The technical solutions of the present utility model will be further specifically described below through specific embodiments in combination with the drawings:

[0033] Embodiment 1: The present utility model provides a pipe fitting turning device. As Figures 1-4 shown, it includes a material rack 3, a bracket 2, and several turning plate assemblies 1. Among them, the bracket 2 is used to place the pipe fittings 4 to be processed, the material rack 3 is used to pick up the pipe fittings 4 and send the pipe fittings 4 to a sawing machine for processing. The turning plate assembly 1 includes a turning seat 13 and a turning seat bottom plate 14. The turning seat 13 is fixed on the turning seat bottom plate 14 by bolts, and the turning seat bottom plate 14 is fixed on the bracket 2.

[0034] As Figure 5 , Figure 6 and Figure 7 shown, a power assembly is arranged below the turning seat 13. In this embodiment, the power assembly adopts a turning oil cylinder 12. The oil cylinder can provide more stable power. The turning oil cylinder 12 is composed of an oil cylinder and an oil cylinder rod inside the oil cylinder. A cylinder lower seat 122 is arranged at the lower end of the turning oil cylinder 12. The cylinder lower seat 122 is fixed on the turning plate bottom plate to ensure that the turning oil cylinder 12 can provide sufficient power. The cylinder lower seat 122 is connected to the turning oil cylinder 12 through a cylinder lower pin. An oil cylinder upper seat 121 is arranged at the upper end of the turning oil cylinder 12, and an oil cylinder upper seat 121 pin hole is arranged on the oil cylinder upper seat 121.

[0035] As Figure 8 and Figure 9As shown in the figure, a lever 11 is arranged above the turnover seat 13. The lever 11 includes a hinge cylinder 113, a hinge part 112, and a blanking plate 111. A rotating shaft is arranged inside the hinge cylinder 113, and the length of the rotating shaft is longer than that of the hinge cylinder 113. Two bearing seats are fixed on the top surface of the turnover seat 13, and the two ends of the rotating shaft are respectively installed and fixed on the two bearing seats, so that the lever 11 is hinged to the turnover seat 13 to realize the rotation of the lever 11, ensuring that the lever 11 can lift the pipe fitting 4 by rotation when turnover is required; the hinge part 112 and the blanking plate 111 are vertically arranged. A pin hole of the hinge part 112 is arranged at the lower end of the hinge part 112. The lever 11 and the turnover oil cylinder 12 are hinged together through the pin hole of the hinge part 112 and the pin hole of the upper oil cylinder seat 121 by an upper oil cylinder pin. The turnover oil cylinder 12 can provide power for the lever 11 to control the rotation of the lever 11 to lift or lower the pipe fitting 4 to realize automatic turnover; the blanking plate 111 part of the lever 11 is used to lift the pipe fitting 4. The top surface of the blanking plate 111 is a blanking inclined surface 1111 with a small angle. One end of the blanking inclined surface 1111 far from the material rack 3 is higher than the end close to the material rack 3, so that after the pipe fitting 4 is taken, the pipe fitting 4 can automatically slide towards the material rack 3 on the blanking inclined surface 1111. A buffer inclined surface 1112 is arranged at the end close to the material rack 3. The buffer inclined surface 1112 and the blanking inclined surface 1111 form a groove at the intersection, so that when the pipe fitting 4 slides down from the blanking inclined surface 1111 to the buffer inclined surface 1112, it will slide onto the buffer inclined surface 1112, and the sliding speed of the pipe fitting 4 will gradually slow down. When the speed is reduced to 0, it will slide back onto the blanking inclined surface 1111. Subsequently, the pipe fitting 4 will make a reciprocating motion near the groove until finally the pipe fitting 4 stops at the groove, preventing the pipe fitting 4 from directly hitting the material rack 3 or colliding between the pipe fittings 4 and causing damage to the pipe fitting 4.

[0036] Specifically, when the turnover oil cylinder 12 rises, it will push the hinge part 112 of the lever 11 through the upper oil cylinder seat 121. Then, the hinge part 112 will push the blanking plate 111 to move. At this time, since the blanking plate 111 is hinged to the turnover seat 13, the blanking plate 111 will rotate around the rotating shaft inside the hinge cylinder 113, and the blanking plate 111 will rotate and rise. Then, the blanking inclined surface 1111 will lift the pipe fitting 4. Subsequently, the pipe fitting 4 will automatically slide towards the material rack 3 on the blanking inclined surface 1111. After hitting the buffer inclined surface 1112, the impact force and speed will gradually slow down, and it will make a reciprocating motion near the groove at the intersection of the buffer inclined surface 1112 and the blanking inclined surface 1111 until it stops in the groove. Then, the turnover oil cylinder 12 descends, so that the blanking plate 111 rotates back, and thus the pipe fitting 4 will be placed on the material rack 3. After that, the pipe fitting 4 will be directly transported to the sawing machine for processing.

[0037] Embodiment 2: In this embodiment, a detailed introduction is made to the structure of the bracket 2. An inclined rod 21 with a small angle is provided on the bracket 2. The end of the inclined rod 21 far from the material rack 3 is higher than the end close to the material rack 3. A baffle 22 is provided at the end of the inclined rod 21 close to the material rack 3. It also includes a long vertical rod and a short vertical rod arranged at both ends of the inclined rod 21. Among them, the short vertical rod is arranged at the end close to the material rack 3, and the long vertical rod is arranged at the end far from the material rack 3. The turning plate assembly 1 is fixed on the short vertical rod through the turning seat bottom plate 14. In this embodiment, a total of 4 brackets 2 are adopted, and the 4 brackets 2 are arranged at equal intervals. The brackets 2 are fixed by 4 connecting rods.

[0038] Specifically, the setting of the inclined rod 21 with a small angle on the bracket 2 enables the pipe fittings 4 to be processed to automatically slide towards the end close to the material rack 3 after being placed on the bracket 2, and then be blocked by the baffle 22, so that the pipe fittings 4 can be neatly arranged on the inclined rod 21, facilitating the turning of the turning plate assembly 1. When the turning plate assembly 1 is not working, the height of the material pushing inclined surface 1111 on the material pushing rod 11 in the turning plate assembly 1 is lower than the height of the baffle 22. When the turning plate assembly 1 starts to work, the material pushing plate 111 in the turning plate assembly 1 will rotate and rise around the rotating shaft in the hinge cylinder 113 driven by the rising of the turning oil cylinder 12, thereby lifting the pipe fittings 4. When the pipe fittings 4 are lifted to a height exceeding the height of the baffle 22, the pipe fittings 4 will slide along the material pushing inclined surface 1111 on the material pushing plate 111 to the groove on the material pushing inclined surface 1111. After the turning is completed, the turning oil cylinder 12 will fall, and the material pushing inclined surface 1111 will then drop to the initial position, lower than the height of the baffle 22. Fixing 4 brackets 2 together can increase the overall bearing capacity of the bracket 2 structure. Moreover, the simultaneous operation of the turning plate assemblies 1 on the 4 brackets 2 can improve the turning efficiency, can also place longer pipe fittings 4, and can also directly place bundled pipe fittings 4, which is convenient for operation and saves manpower and material resources.

[0039] Embodiment 3: In this embodiment, a detailed introduction to the rack 3 is as follows: The rack 3 is composed of a number of cross bars and vertical bars to form a rectangular frame structure. The frame structure is more stable, enabling the pipe fittings 4 to be stably transported to the sawing machine for processing, and enhancing the load-bearing capacity, allowing multiple pipe fittings 4 to be transported simultaneously. On the top of the frame structure of the rack 3, multiple groups of bearing seat groups are arranged on two long cross bars that are parallel to each other. Each group of bearing seat groups includes two bearing seats, which are respectively fixed on the two long cross bars and are fixed in a straight line. A roller assembly is also provided on the rack 3. The roller assembly includes a roller 31 and a sprocket 32. The roller 31 and the sprocket 32 are both installed on a rotating shaft, and both ends of the rotating shaft are respectively installed on a group of bearing seats. The number of roller assemblies is the same as the number of bearing seat groups. Among them, the sprocket 32 is arranged at one end of the rotating shaft away from the bracket 2, and all the sprockets 32 are connected by the same chain, enabling the rollers 31 in all the roller assemblies to rotate synchronously, ensuring that the pipe fittings 4 can be smoothly transported to the sawing machine to achieve automatic feeding. A sprocket guard is also provided outside the sprocket 32 and the chain to ensure the normal operation of the chain and the sprocket 32 and prevent interference. In addition, a number of soft cushion blocks 33 with equal intervals are arranged on the long cross bar of the rack 3 away from the bracket 2 at the top, which can play a buffering role and further protect the pipe fittings 4 from being damaged due to collision.

[0040] The turnover plate assembly 1 installed on the short vertical bar of the bracket 2 can place the pipe fittings 4 on the rack 3 after turnover. Specifically, the top plate 111 on the turnover plate assembly 1 is arranged parallel to the roller 31 and can extend in the direction away from the bracket 2 to exceed the axis of the rack 3. The top plate 111 on the turnover plate assembly 1 is lifted by the rising of the turnover oil cylinder 12, so that the top inclined surface 1111 of the top plate 111 will lift the pipe fittings 4 placed on the bracket 2 to a height exceeding the height of the baffle 22, and then the pipe fittings 4 will slide to the groove. Then, during the process of the turnover oil cylinder 12 descending and driving the top plate 111 to fall, the pipe fittings 4 will be placed on the roller assembly and be transported to the sawing machine for processing along with the rotation of the roller 31.

[0041] Next, an introduction to the overall working process of the present utility model is as follows:

[0042] First, the pipe fittings 4 to be processed are placed on one side of the bracket 2 close to the long vertical bar, or the bundled pipe fittings 4 are directly placed on one side of the bracket 2 close to the long vertical bar and then the pipe fittings 4 are untied. The pipe fittings 4 will slide along the inclined rod 21 on the bracket 2 towards one end close to the rack 3. When the pipe fittings 4 slide above the short vertical bar, they will be blocked by the baffle 22 and thus stop, realizing that the pipe fittings 4 can be neatly arranged on the inclined rod 21.

[0043] At this time, the height of the ejector inclined surface 1111 on the ejector plate 111 is lower than the height of the baffle 22. Subsequently, the turnover plate assembly 1 installed on the short vertical rod of the bracket 2 starts to work. The turnover oil cylinder 12 rises. Through the hinge relationship between the upper oil cylinder seat 121 and the hinge part 112, it pushes the ejector plate 111 to rise. There is also a hinge cylinder 113 hinged to the turnover seat 13. Thus, the ejector plate 111 rises in a way that it rotates around the hinge cylinder 113. As the ejector plate 111 rises, the ejector inclined surface 1111 of the ejector plate 111 will lift the pipe fitting 4 blocked by the baffle 22. When multiple pipe fittings 4 need to be taken at the same time or the inner diameter of the pipe fitting 4 is relatively large, because the ejector inclined surface 1111 increases the contact area with the pipe fitting 4, it can also lift the pipe fitting 4. When the pipe fitting 4 is lifted above the height of the baffle 22, the pipe fitting 4 can slide along the ejector inclined surface 1111 towards the material rack 3. When the pipe fitting 4 slides to the buffer inclined surface 1112, it will slide onto the buffer inclined surface 1112. The sliding speed of the pipe fitting 4 will gradually slow down. Then, after the speed of the pipe fitting 4 drops to 0, it will slide back down to the ejector inclined surface 1111. Thus, the pipe fitting 4 will move back and forth near the groove and finally stop at the groove.

[0044] Subsequently, the turnover oil cylinder 12 starts to descend. Through the hinge structure, the ejector plate 111 will rotate and descend accordingly. The pipe fitting 4 on the ejector inclined surface 1111 will also descend therewith. The pipe fitting 4 will be placed on the material rack 3. The turnover plate assembly 1 will continue to descend a certain distance to a position initially lower than the height of the baffle 22, which will not affect the rotation of the sprocket 32 on the material rack 3 for transporting the pipe fitting 4 driven by the same chain. The roller 31 rotates coaxially with the sprocket 32. Thus, the pipe fitting 4 is transported to the sawing machine for processing.

[0045] The beneficial effects of the present utility model are as follows: The turnover plate assembly 1 automatically turns over by the rise and fall of the turnover oil cylinder 12 and transmits the power to the ejector plate 111 through the hinge structure, which can achieve precise turnover. Moreover, during the turnover process, the contact area between the pipe fitting 4 and the ejector plate 111 is relatively large, and the pipe fitting 4 will be more stable. The setting of the small-angle ejector inclined surface 1111 and the buffer inclined surface 1112 enables the pipe fitting 4 to slide towards the groove automatically and smoothly after being taken out, and this process will not cause collision damage to the pipe fitting 4, ensuring the integrity of the pipe fitting 4. The design of the small-angle inclined rod 21 and the baffle 22 on the bracket 2 enables the pipe fittings 4 to be automatically arranged neatly after being placed on the bracket 2, facilitating the turnover operation of the turnover plate assembly 1 and preventing collision between the pipe fittings 4. The roller assembly provided on the material rack 3 simplifies the feeding process and realizes self-feeding. After the pipe fitting 4 is placed on the material rack 3, it can be directly sent to the sawing machine for processing as the roller 31 rolls. The soft cushion block 33 provided on the material rack 3 can ensure that the pipe fitting 4 will not be damaged during the transportation process. After the turnover plate assembly 1 completes the turnover, it is directly fed by the material rack 3 for processing, improving the processing efficiency of turnover and loading.
