Description

Technical Field

[0001] This utility model relates to the technical field of round tube chamfering machines, specifically to a feeding device for a round tube chamfering machine. Background Technology

[0002] After being cut, long round tubes become equidistant short round tubes. The short round tubes need to be fed into a round tube chamfering machine for chamfering. Existing round tube chamfering machines are all equipped with horizontal inlets and outlets. The chamfering of metal round tubes is completed by mechanical force inside the chamfering machine.

[0003] For example, the authorization announcement number "CN217991795U" is named a feeding device for a round tube chamfering machine. The entire feeding process of the transmission mechanism is fully mechanized, easy to position, and simple to operate, which improves processing quality and production efficiency. Existing feeding devices for round tube chamfering machines use a pusher cylinder to directly push the round tube into the chamfering machine's clamping cavity. However, the round tubes that need to be chamfered still require manual intervention to fill in the round tubes when feeding them into the feeding device. Therefore, the degree of automation is not high, and the working interval required to complete the feeding of the round tube chamfering machine each time is relatively long, which is not conducive to improving the efficiency of the feeding device for the round tube chamfering machine.

[0004] Meanwhile, the existing round tube chamfering machine's feeding device needs to be aligned with the chamfering machine's inlet. However, there is no additional positioning structure between the chamfering machine's inlet and the transmission mechanism that operates the feeding device. This makes it impossible to completely confirm that the front end of the transmission mechanism is precisely aligned with the chamfering machine's inlet. Therefore, during the process of pushing the round tube for feeding, it is easy for it to bump against the edge of the chamfering machine, causing damage to the end of the round tube. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of the low automation level of the feeding device of the existing round tube chamfering machine, the long working interval required for each round tube chamfering machine feeding, and the easy occurrence of the round tube hitting the edge of the chamfering machine during the pushing feeding process, which causes damage to the end of the round tube. Therefore, a feeding device for round tube chamfering machine is proposed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A feeding device for a round tube chamfering machine is designed, comprising a feeding device housing, a support frame, and a chamfering machine body. The feeding device housing is fixedly connected to the top of the support frame, and the chamfering machine body is movably disposed at one end of the feeding device housing. A round tube pushing feeding structure is provided on the inner side of the feeding device housing, and an automatic and convenient round tube feeding structure is provided on the top of the feeding device housing. A feeding device positioning structure is provided on one side of the chamfering machine body.

[0007] Preferably, the automatic and convenient feeding structure for the round tube includes a crossbeam and a feeding port. The crossbeam is fixedly connected to one side of the top of the feeding device box. A feeding platform is fixedly installed above the crossbeam. A conveyor belt is fixedly installed above the feeding platform. The feeding port is fixedly opened at the top of the outer wall of the feeding device box. A limit block is fixedly installed on the upper outer wall of the feeding device box.

[0008] Preferably, a circular tube body is movably placed above the conveyor belt, and the lower part of the outer wall of the limiting block is positioned opposite to the top of the feeding port.

[0009] Preferably, the circular tube push feeding structure includes a side plate and a controller. The side plate is fixedly connected to the outer wall of the feeding device housing. A hydraulic cylinder is fixedly installed at the top of the side plate. A push plate is fixedly connected to the front end of the hydraulic cylinder. The controller is fixedly connected to the lower end of the feeding device housing and is electrically connected to a pressure sensor.

[0010] This setting is equipped with a pressure sensor electrically connected to the controller. The pressure sensor is made of a pressure-sensitive resistor. The controller can identify whether there is a round tube material to be conveyed on the pressure sensor. Therefore, when the round tube body is sent into the feeding device box, the pressure sensor detects the pressure change and immediately starts the hydraulic cylinder above the horizontal side plate through the controller. The hydraulic cylinder pushes the push plate forward, and the push plate completes the operation of feeding the round tube body into the chamfering machine body.

[0011] Preferably, the upper part of the pressure sensor is movably connected to the circular tube, and the front end of the push plate is disposed opposite to one side of the circular tube.

[0012] Preferably, the positioning structure of the feeding device includes an overlapping plate and an extension seat. The extension seat is fixedly connected to the lower end of the outer wall of the chamfering machine body. The overlapping plate is movably connected above the extension seat. A magnetic suction plate is fixedly installed on the side wall of the chamfering machine body. Multiple positioning blocks are movably connected to the outer side of the magnetic suction plate.

[0013] This feature involves an extension seat protruding below the main body of the chamfering machine, while an overlap plate is fixed below the feeding device housing. To ensure precise alignment between the outlet pipe of the feeding device housing and the feed inlet of the chamfering machine, the overlap plate is attached to the top of the extension seat, and the positioning block is aligned with the magnetic plate. Because the positioning block is made of iron, it can be magnetically attracted and adhered to the magnetic plate. This ensures that the end of the feeding device housing is aligned with the outer side of the chamfering machine, thus facilitating the alignment of the rightmost end of the feeding device housing with the feed inlet of the chamfering machine, resulting in smoother and faster feeding of the round tube.

[0014] Preferably, the plurality of positioning blocks are fixedly connected to the outer wall of the end of the feeding device housing, and the top of the overlapping plate is fixedly connected to the bottom of the feeding device housing.

[0015] The present invention proposes a feeding device for a round tube chamfering machine, which has the following advantages: a crossbeam is welded horizontally to one side of the feeding device housing, and a feeding platform is fixed on the crossbeam to guide the sliding of the round tube body to be chamfered. When the conveyor belt is powered on, it can rotate and drive the horizontally placed round tube body above to be transported horizontally. Therefore, the round tube body after mechanical cutting can move along the conveyor belt towards the limiting block at the other end. The limiting block can restrict the running limit position of the round tube body. When the round tube body passes the feeding port, it will fall directly into the feeding device housing and wait to be pushed for chamfering. By guiding the round tubes to be chamfered to be fed in sequence in a convenient manner, the degree of automation is higher and the round tube feeding speed is faster.

[0016] The extension seat protrudes below the main body of the chamfering machine, while the overlapping plate is fixed below the feeding device box. To ensure precise alignment between the outlet pipe position of the feeding device box and the feed inlet of the chamfering machine, the overlapping plate is attached to the top of the extension seat, and the positioning block is aligned with the magnetic plate. Because the positioning block is made of iron, it can be magnetically attracted and adhered to the magnetic plate. This ensures that the end of the feeding device box is aligned with the outer side of the chamfering machine, thus facilitating the alignment of the rightmost end of the feeding device box with the feed inlet of the chamfering machine. This makes the feeding of the round tube smoother and faster, reducing the risk of the round tube bumping against the edge of the chamfering machine during the feeding process.

[0019] The present invention will be further described below with reference to the accompanying drawings: Example

[0020] Please see Figure 1-6 In this embodiment, a feeding device for a round tube chamfering machine includes a feeding device housing 1, a support frame 2, and a chamfering machine body 3. The feeding device housing 1 is fixedly connected to the top of the support frame 2. The support frame 2 supports the horizontally oriented feeding device housing 1, aligning one end of the feeding device housing 1 with the feed inlet of the chamfering machine body 3. The chamfering machine body 3 is movably disposed at one end of the feeding device housing 1. The chamfering machine body 3 is selected from round tube chamfering and bending machines of model YS-75NCT or YS-89NCT, which are suitable for tube bending processing. The inner side of the feeding device housing 1 is provided with a round tube pushing feeding structure 5, the top of the feeding device housing 1 is provided with a round tube automatic and convenient feeding structure 6, and one side of the chamfering machine body 3 is provided with a feeding device positioning structure 7.

[0021] The automatic and convenient circular tube feeding structure 6 includes a crossbeam 61 and a feeding port 65. The crossbeam 61 is fixedly connected to one side of the top of the feeding device box 1. The crossbeam 61 is horizontally welded to one side of the feeding device box 1. A feeding platform 62 that can guide the circular tube body 4 to be chamfered is fixed on the crossbeam 61. The feeding platform 62 is fixedly installed above the crossbeam 61. An electrically driven roller conveyor belt is installed on the feeding platform 62. When the conveyor belt 63 is connected to the power supply, it can rotate and drive the horizontally placed circular tube body 4 to be horizontally transported. A conveyor belt 63 is fixedly installed above the feeding platform 62, and the feeding port 65 is fixedly opened at the top of the outer wall of the feeding device box 1. Therefore, the round tube body 4 after mechanical production and cutting can move along the conveyor belt 63 towards the limiting block 64 at the other end. The limiting block 64 can limit the running limit position of the round tube body 4. When the round tube body 4 passes the feeding port 65, it will fall directly into the inside of the feeding device box 1 and wait to be pushed for chamfering. The limiting block 64 is fixedly installed on the upper outer wall of the feeding device box 1.

[0022] A circular tube body 4 is movably placed above the conveyor belt 63, and the lower part of the outer wall of the limiting block 64 is positioned opposite to the top of the feeding port 65.

[0023] The circular tube push feeding structure 5 includes a side plate 51 and a controller 55. The side plate 51 is fixedly connected to the outer wall of the feeding device box 1. A hydraulic cylinder 52 is fixedly installed at the top of the side plate 51. A push plate 53 is fixedly connected to the front end of the hydraulic cylinder 52. The controller 55 is fixedly connected to the lower end of the feeding device box 1. The controller 55 is electrically connected to a pressure sensor 54. The pressure sensor 54 is made of a piezoresistor. The controller 55 can identify whether there is circular tube material to be conveyed on the pressure sensor 54. Therefore, when the circular tube body 4 is sent into the feeding device box 1, the pressure sensor 54 detects the pressure change and immediately starts the hydraulic cylinder 52 above the horizontal side plate 51 through the controller 55. The hydraulic cylinder 52 pushes the push plate 53 forward. The push plate 53 completes the operation of feeding the circular tube body 4 into the chamfering machine body 3. The upper part of the pressure sensor 54 is movably connected to the circular tube 4, and the front end of the push plate 53 is set opposite to one side of the circular tube 4.

[0024] The feeding device positioning structure 7 includes an overlapping plate 71 and an extension seat 72. The extension seat 72 is fixedly connected to the lower end of the outer wall of the chamfering machine body 3 and protrudes from the bottom of the chamfering machine body 3. The overlapping plate 71 is fixed to the bottom of the feeding device housing 1. In order to ensure that the outlet pipe position of the feeding device housing 1 and the feed inlet of the chamfering machine body 3 can be accurately aligned, the overlapping plate 71 is attached to the top of the extension seat 72, and the positioning block 73 is aligned with the magnetic suction plate 74. Because the positioning block 73 is made of iron, it can be magnetically attracted and adhered to the magnetic suction plate 74. This ensures that the end of the feeding device box 1 is aligned with the outer side of the chamfering machine body 3, thus facilitating the alignment of the rightmost end of the feeding device box 1 with the feed inlet of the chamfering machine body 3, making the feeding of the round tube body 4 smoother and faster. An overlapping plate 71 is movably connected above the extension seat 72, and a magnetic suction plate 74 is fixedly installed on the side wall of the chamfering machine body 3. Multiple positioning blocks 73 are movably connected to the outer side of the magnetic suction plate 74, and the multiple positioning blocks 73 are fixedly connected to the outer wall of the end of the feeding device box 1. The top of the overlapping plate 71 is fixedly connected to the bottom of the feeding device box 1.

[0025] Working principle: The feeding device for the round tube chamfering machine is used to feed the metal round tubes that need to enter the chamfering machine; A crossbeam 61 is welded horizontally to one side of the feeding device box 1. A feeding platform 62 is fixed on the crossbeam 61 to guide the circular tube body 4 to be chamfered to slide. An electric-driven roller conveyor belt is installed on the feeding platform 62. When the conveyor belt 63 is powered on, it can rotate and drive the horizontally placed circular tube body 4 to be conveyed horizontally. Therefore, the circular tube body 4 after mechanical production and cutting can move along the conveyor belt 63 towards the limit block 64 at the other end. The limit block 64 can limit the running limit position of the circular tube body 4. When the circular tube body 4 passes the feeding port 65, it will fall directly into the feeding device box 1 and wait to be pushed for chamfering. The controller 55 is electrically connected to a pressure sensor 54, which is made of a pressure-sensitive resistor. The controller 55 can detect whether there is a round tube material to be conveyed on the pressure sensor 54. Therefore, when the round tube body 4 is fed into the feeding device box 1, the pressure sensor 54 detects the pressure change and immediately starts the hydraulic cylinder 52 above the transverse side plate 51 through the controller 55. The hydraulic cylinder 52 pushes the push plate 53 forward, and the push plate 53 completes the operation of feeding the round tube body 4 into the chamfering machine body 3. The extension seat 72 protrudes below the chamfering machine body 3, while the overlapping plate 71 is fixed below the feeding device box 1. In order to ensure that the outlet position of the feeding device box 1 and the feed port of the chamfering machine body 3 can be accurately aligned, the overlapping plate 71 is attached to the top of the extension seat 72, and the positioning block 73 is aligned with the magnetic suction plate 74. Because the positioning block 73 is made of metal iron, it can be attracted and attached to the magnetic suction plate 74 by magnetic attraction. This ensures that the end of the feeding device box 1 is aligned with the outer side of the chamfering machine body 3, thus facilitating that the rightmost end of the feeding device box 1 can be aligned with the feed port of the chamfering machine body 3, and the feeding of the round tube body 4 is smoother and faster.
