Description

Technical Field

[0001] This application relates to the technical field of clean steel pipe processing equipment, and in particular to an automatic clean steel pipe cutting machine. Background Technology

[0002] Currently, the clean steel pipe automatic cutting machine is an automated device specifically designed for cutting stainless steel pipes, steel pipes, and other metal pipes. It is widely used in industries such as construction, chemical, food, and pharmaceutical, and is particularly suitable for environments with high hygiene requirements.

[0003] One type of clean steel pipe cutting machine in the related technology mainly includes a frame, on which a circular saw for cutting steel pipes is rotatably mounted, and a clamp for holding and fixing the steel pipes is also installed on the frame. Before processing, the steel pipe is first clamped and fixed on the frame by the clamp, and then the circular saw cuts the steel pipe. However, after each cut, the remaining steel pipe needs to be manually readjusted and clamped. This manual adjustment is not only time-consuming and labor-intensive, but also reduces the cutting efficiency of the steel pipes to some extent. Utility Model Content

[0004] This application provides a clean steel pipe automatic cutting machine, which is convenient to use, saves time and effort, and can improve the efficiency of steel pipe cutting.

[0005] The automatic clean steel pipe cutting machine provided in this application adopts the following technical solution:

[0006] An automatic steel pipe cutting machine for cleanliness includes a frame on which an electric circular saw is mounted. The frame also includes multiple sets of clamping assemblies located below the electric circular saw, arranged sequentially at intervals. Each clamping assembly includes a first clamp and a second clamp arranged opposite to each other. The first clamp is fixedly mounted on the frame. The clamping assembly also includes a clamping cylinder fixedly mounted on the frame, and the second clamp is mounted on the piston rod of the clamping cylinder. A clamping groove for inserting steel pipes is formed between the first and second clamps.

[0007] The frame is also equipped with a feeding rack for placing steel pipes, and the feeding rack is equipped with a pushing component for pushing the steel pipes into the clamping groove.

[0008] The frame is also equipped with a triggering component, and the feeding rack and the triggering component are located on both sides of the clamping component, respectively. The triggering component includes a micro switch and a controller. The micro switch is located on the discharge path of the steel pipe. The controller is used to receive the triggering command sent by the micro switch and control the clamping cylinder and the triggering component to complete the specified action.

[0009] Preferably, the pushing assembly includes multiple drive rods rotatably mounted on the feeding rack, and gears symmetrically arranged at both ends of the drive rods, the gears being coaxial with their respective drive rods; the drive rods are parallel to each other, and each drive rod is arranged sequentially at intervals along the steel pipe feeding direction; each gear on the same side of the drive rod is externally meshed with the same chain; the pushing assembly also includes a pushing motor for driving the drive rods to rotate, and a pushing plate mounted on the chain above the drive rods is provided, the pushing plate being used to push the steel pipe into the clamping groove.

[0010] Preferably, the triggering component further includes a mounting base, the micro switch is mounted on the mounting base, and the trigger end of the micro switch is provided with a trigger plate facing the clamping groove. The trigger plate is used to contact the steel pipe to control the triggering of the micro switch.

[0011] Preferably, the mounting base is slidably mounted on the frame along the discharge direction of the steel pipe, and a fastener is threaded onto the mounting base for tightening and fixing the mounting base onto the frame.

[0012] Preferably, the frame is further provided with a support frame located between the clamping assembly and the mounting base, the support frame being used to place the steel pipe after cutting.

[0013] Preferably, the frame is provided with a positioning cylinder located between the clamping assembly and the unloading rack. The extension and retraction direction of the piston rod of the positioning cylinder is consistent with the extension and retraction direction of the piston rod of the clamping cylinder. The positioning cylinder is used to position the steel pipe.

[0014] Preferably, a cutting frame is provided on the frame, and the electric circular saw is rotatably mounted on the cutting frame; one end of the cutting frame is rotatably mounted on the frame, and a lifting cylinder for driving the cutting frame to rise and fall is also provided on the frame.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] By adjusting the mounting position of the mounting base, the position of the micro switch can be adjusted, thereby meeting the cutting requirements of steel pipes of different lengths, expanding the range of applications, and making it more flexible and convenient.

[0017] After the steel pipe is cut, as the first and second clamps separate, the cut steel pipe falls onto the support frame under its own weight, thus achieving automatic unloading of the steel pipe. This method is convenient, time-saving, and labor-saving, improving the efficiency of steel pipe cutting.

[0018] The pusher assembly enables automatic pushing and feeding of steel pipes, greatly freeing up manpower and making it more convenient and faster.

[0019] The high degree of automation further improves the cutting efficiency of steel pipes. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses an automatic cutting machine for clean steel pipes.

[0028] Reference Figure 1 , Figure 2 The automatic steel pipe cutting machine includes a frame 1, on which a cutting frame 9 is mounted. The lower end of the cutting frame 9 is rotatably mounted on the frame 1. An electric circular saw 2 for cutting steel pipes is rotatably mounted on the upper end of the cutting frame 9. The blade of the electric circular saw 2 is driven to rotate by an external motor. A lifting cylinder 10 is also mounted on the frame 1, located on one side of the cutting frame 9. The piston rod of the lifting cylinder 10 is rotatably connected to the cutting frame 9. The lifting cylinder 10 drives the cutting frame 9 to rotate around a rotation axis connected to the frame 1. When the piston rod of the lifting cylinder 10 extends outward, the lifting cylinder 10 pushes the electric circular saw 2 downward; conversely, when the piston rod retracts, the lifting cylinder 10 lifts the electric circular saw 2 upward.

[0029] like Figure 2 , Figure 3As shown, the frame 1 is also equipped with multiple sets of clamping assemblies 3 located below the electric circular saw 2, with each set of clamping assemblies 3 arranged sequentially at intervals along the feeding direction of the steel pipe. Each clamping assembly 3 includes a first clamp 30 and a second clamp 31 arranged opposite to each other, with the first clamp 30 fixedly mounted on the frame 1. The clamping assembly 3 also includes a clamping cylinder 32 fixedly mounted on the frame 1, with the second clamps 31 respectively fixedly mounted on the piston rod of their respective clamping cylinders 32. The clamping cylinders 32 are used to drive the second clamps 31 to move closer to or further away from their respective first clamps 30.

[0030] like Figure 2 , Figure 3 As shown, a clamping groove 33 for inserting steel pipe is formed between the first clamp 30 and the second clamp 31, which are arranged opposite to each other. When the steel pipe is inserted into the clamping groove 33, the second clamp 31 is driven to move closer to the first clamp 30 by the clamping cylinder 32 until the steel pipe is tightened and fixed in the clamping groove 33. At this time, the subsequent cutting process can be carried out.

[0031] like Figure 4 As shown, the frame 1 is also equipped with a feeding rack 4 for placing the steel pipes to be cut. The feeding rack 4 is equipped with a pushing assembly 5, which is used to push the steel pipes into the clamping groove 33. The pushing assembly 5 includes multiple drive rods 50 rotatably mounted on the feeding rack 4, and gears 51 symmetrically arranged at both ends of the drive rods 50. The gears 51 are coaxially arranged with their respective drive rods 50. The drive rods 50 are horizontally arranged and parallel to each other, and are arranged sequentially at intervals along the steel pipe feeding direction.

[0032] like Figure 3 , Figure 4 As shown, the gears 51 on the same side of the drive rod 50 are externally meshed with the same chain 52. The pushing assembly 5 also includes a pushing motor 53 for driving the drive rod 50 to rotate. When the pushing motor 53 drives one of the drive rods 50 to rotate, the gears 51 on both sides will rotate synchronously under the transmission of the chain 52. A pushing plate 54 is fixedly installed between the two chains 52 and mounted above the drive rod 50. The pushing plate 54 is used to push the steel pipe placed on the drive rod 50 into the clamping groove 33.

[0033] like Figure 1 As shown, a positioning cylinder 8 is fixedly installed on the frame 1 between the clamping assembly 3 and the unloading rack 4. The extension and retraction direction of the piston rod of the positioning cylinder 8 is the same as that of the piston rod of the clamping cylinder 32. The positioning cylinder 8 is used to push the steel pipe to a limit position on the frame 1, thereby positioning the steel pipe to ensure that the steel pipe can be smoothly inserted into the clamping slot 33.

[0034] like Figure 1 , Figure 5As shown, a trigger assembly 6 is also provided on the frame 1, and the feeding rack 4 and the trigger assembly 6 are located on both sides of the clamping assembly 3, respectively. The trigger assembly 6 includes a micro switch 60 and a controller 61. The controller 61 is used to receive the trigger command sent by the micro switch 60 and send the corresponding control command to control the clamping cylinder 32 and the trigger assembly 6 to complete the specified action.

[0035] The controller 61 may include a central processing unit such as a CPU or MPU, or a host system built around a CPU or MPU, including hardware or software. Users can freely control the controller 61 through programming, making it operate according to their wishes. The controller 61 can control local data transfer / traceability components, remote data transfer / traceability components, and remote communication components through internal protocols. Internal protocols may include some or all of the following protocols: human-machine interface protocols, software / hardware (interface) protocols, chip bus (C-Bus) protocols, and internal bus (I-Bus) protocols. With the development of integrated circuit technology, some protocols that belong to external bus (E-Bus) have also become internal protocols after being integrated into the chip along with the external bus (E-Bus).

[0036] The specific control actions are as follows: When the pusher motor 53 receives the pusher command from the controller 61, the pusher motor 53 drives the gear 51 to rotate. As the gear 51 rotates, the chain 52 drives the pusher plate 54 to gradually push the steel pipe placed on the drive rod 50 towards the clamping groove 33. During the pusher process, the steel pipe is limited by the piston rod of the positioning cylinder 8, which ensures that the steel pipe is smoothly inserted into the clamping groove 33. The micro switch 60 is located on the discharge path of the steel pipe. As the steel pipe is inserted into the clamping groove 33 in sequence, the end of the steel pipe will gradually approach the trigger end of the micro switch 60.

[0037] When the end of the steel pipe contacts the trigger end of the micro switch 60, as the micro switch 60 is triggered, the controller 61 will control the pusher motor 53 to stop pushing the material, and then control the clamping cylinder 32 to clamp and fix the steel pipe in the clamping groove 33. Then, the controller 61 will control the lifting cylinder 10 to move the electric circular saw 2 in operation downward until the electric circular saw 2 cuts the steel pipe located at the designated work position.

[0038] After the electric circular saw 2 finishes cutting the steel pipe, the lifting cylinder 10 will drive the electric circular saw 2 to rise and reset under the control of the controller 61. Then, the second clamp 31 will separate from the first clamp 30 under the drive of the clamping cylinder 32, and the cut steel pipe can be taken out from the clamping groove 33, and then a new round of cutting work can continue.

[0039] like Figure 5As shown, the trigger assembly 6 also includes a mounting base 62, which is slidably mounted on the frame 1 along the discharge direction of the steel pipe. A fastener 64, which is a bolt in this embodiment, is threaded onto the bottom of the mounting base 62. The fastener 64 is used to tighten and fix the mounting base 62 onto the frame 1. A micro switch 60 is fixedly mounted on the mounting base 62. The trigger end of the micro switch 60 is provided with a trigger plate 63 facing the clamping groove 33, which is used to contact the steel pipe. The trigger plate 63 can further increase the contact area between the steel pipe and the trigger end of the micro switch 60, thereby ensuring that the steel pipe can smoothly trigger the micro switch 60.

[0040] By adjusting the mounting position of the mounting base 62, the position of the micro switch 60 can be adjusted, thereby meeting the cutting requirements of steel pipes of different lengths, expanding the range of applications, and making it more flexible and convenient.

[0041] like Figure 2 , Figure 3 As shown, a support frame 7 is also provided on the frame 1 between the clamping assembly 3 and the mounting base 62. The support frame 7 is used to place the steel pipe after cutting. After the steel pipe is cut, as the first clamp 30 and the second clamp 31 separate, the cut steel pipe will fall onto the support frame 7 under its own weight, thereby realizing automatic unloading of the steel pipe. It is convenient to use, saves time and effort, and improves the cutting efficiency of steel pipe.

[0042] The implementation principle is as follows: When the pusher motor 53 receives the pusher command from the controller 61, the pusher motor 53 drives the gear 51 to rotate. As the gear 51 rotates, the chain 52 drives the pusher plate 54 to gradually push the steel pipe placed on the drive rod 50 towards the clamping groove 33. During the pusher process, the steel pipe is limited by the piston rod of the positioning cylinder 8, which ensures that the steel pipe is smoothly inserted into the clamping groove 33. The micro switch 60 is located on the discharge path of the steel pipe. As the steel pipe is inserted into the clamping groove 33 in sequence, the end of the steel pipe will also gradually approach the trigger end of the micro switch 60.

[0043] When the end of the steel pipe contacts the trigger end of the micro switch 60, as the micro switch 60 is triggered, the controller 61 will control the pusher motor 53 to stop pushing the material, and then control the clamping cylinder 32 to clamp and fix the steel pipe in the clamping groove 33. Then, the controller 61 will control the lifting cylinder 10 to move the electric circular saw 2 in operation downward until the electric circular saw 2 cuts the steel pipe located at the designated work position.

[0044] After the electric circular saw 2 finishes cutting the steel pipe, the lifting cylinder 10 will drive the electric circular saw 2 to rise and reset under the control of the controller 61. Then, the second clamp 31 will separate from the first clamp 30 under the drive of the clamping cylinder 32, and the cut steel pipe can be taken out from the clamping groove 33, and then a new round of cutting work can continue.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
