Description

Technical Field

[0001] The invention belongs to the copper tube processing industry, and particularly relates to an automatic deburring machine for copper tubes. Background Art

[0002] As we all know, during the copper tube processing, sawing is required to meet the size requirements. However, there will be burrs on the port after sawing. If the burrs are not polished, the quality of the product will be seriously affected.

[0003] In view of this, manual deburring is performed after the copper tube is sawed. Therefore, it is not only inefficient, but also labor-intensive for employees, and the phenomenon of missing grinding often occurs. Summary of the invention

[0004] In order to overcome the defects of the prior art, the object of the present invention is to provide an automatic deburring machine for copper tubes.

[0005] To achieve the above object, the present invention provides a copper tube automatic deburring machine, which comprises:

[0006] frame;

[0007] The copper tube automatic conveying unit comprises two conveying tube groups which are spaced and aligned along the length direction of the copper tube, wherein each conveying tube group comprises a conveying tube channel, a grinding channel and a pipe outlet channel, the conveying tube channel comprises a main channel from top to bottom with a lower discharge port located above the grinding channel, and an auxiliary channel which is connected with a feed port at the upper part of the main channel and is mounted on the frame of the automatic deburring machine, wherein the width of the main channel is 1 to 1.5 times of the outer diameter of the copper tube, and the height of the discharge port from the grinding channel is equal to the outer diameter of the copper tube; the grinding channel is horizontally arranged and the abrasive inlet is connected with the discharge port, and the copper tubes which fall from the discharge port to the grinding channel one by one can be rolled or / and slid from the abrasive inlet to the abrasive outlet along the length direction of the grinding channel; the pipe outlet channel is connected with the abrasive outlet of the grinding channel and guides the polished copper tube out of the frame,

[0008] The invention discloses an automatic deburring unit for copper tubes, comprising deburring rollers corresponding to grinding channels one by one and extending along the length direction of the grinding channels, and drivers driving the deburring rollers to rotate respectively, wherein two deburring rollers are respectively arranged at the relatively outer sides of two grinding channels to form a deburring zone, and each deburring roller comprises a roller body extending along the direction of the copper tube being sent to the deburring zone, and a brush body distributed circumferentially around the roller body, and the brush body parts at the relatively inner sides of the two deburring rollers are correspondingly arranged on the transmission path of the end face of the copper tube, and when the two deburring rollers rotate towards each other, the brush body removes the burrs on the end face of the copper tube passing through the deburring zone as the roller body rotates.

[0009] Preferably, the main channel includes a first panel and a second panel which are parallel to each other and perpendicular to the grinding channel and correspond to the left and right sides, wherein the lower ends of the first panel and the second panel are flush to form a discharge port, the upper end of the second panel is located above the upper part of the first panel, and the upper part of the first panel and the inner wall of the corresponding second panel form the feed port. The flush-arranged discharge port facilitates the copper tubes stacked side by side between the feed port and the discharge port to enter the grinding channel one by one; the upper end of the second panel is arranged to protrude, so that the copper tubes are blocked when they roll down from the auxiliary channel, so that the copper tubes can fall into the feed port.

[0010] Preferably, the auxiliary channel is tilted upward and leftward from the upper part of the first panel to form a first ramp panel, wherein the first ramp panel is mounted on the frame, and the upper end of the first ramp panel emerges from the frame. The ramp setting facilitates the free rolling of the copper pipe.

[0011] Furthermore, the first ramp panel and the first panel are integrally formed, and the length of the second panel extending upward from the feed inlet is at least twice the outer diameter of the copper tube.

[0012] In this example, the second panel extends upward from the feed port and emerges from the top of the frame. The advantage of this arrangement is that it prevents the copper pipe from turning over the second panel and failing to fall into the feed port when rolling down.

[0013] According to another specific implementation and preferred aspect of the present invention, the grinding channel includes an annular conveyor belt located below, a third panel located above the annular conveyor belt and arranged parallel to the upper portion of the annular conveyor belt, wherein a copper pipe channel is formed between the third panel and the upper portion of the annular conveyor belt, and the driving wheels of the annular conveyor belts of the two pipe delivery groups are synchronously connected through a transmission shaft. Under the movement of the annular conveyor belt, the copper pipe rolls freely and moves toward the discharge port.

[0014] Specifically, the third panel extends horizontally to the right from the right side of the bottom of the second panel, and the bottom surface of the third panel is flush with the bottom surface of the second panel. This arrangement not only facilitates the copper tube from the discharge port to smoothly enter the grinding channel, but also forms a limiting force during the grinding process to prevent the copper tube from moving around during deburring, causing confusion in the transfer of the copper tube.

[0015] Preferably, the second panel and the third panel are integrally formed to facilitate actual processing.

[0016] In addition, the grinding channel also includes a supporting inner frame arranged inside the endless conveyor belt and capable of supporting the upper part of the endless conveyor belt upward to be in a horizontal state. In this way, the parallelism between the upper part of the endless conveyor belt and the third panel can be ensured to ensure the transmission of the copper pipe during grinding.

[0017] At the same time, the pipe outlet passage comprises a second ramp panel which is tilted from left to right and from top to bottom, so that the copper pipe can be freely rolled out of the rack through the second ramp panel.

[0018] Specifically, the angle of the second ramp panel can be adjusted, and the length can also be selected according to actual needs, thereby facilitating the collection of the copper tube after deburring.

[0019] According to a specific implementation and preferred aspect of the present invention, the transmission shaft is in the shape of a square tube, a square hole matching the square tube is provided at the center of the driving wheel, and the deburring machine further comprises a motor arranged on the frame, and a transmission component for connecting the motor to the transmission shaft. The square tube and the square hole cooperate to ensure that the two endless conveyor belts move synchronously.

[0020] Preferably, the driver includes a frame correspondingly arranged on the frame of the automatic deburring machine and correspondingly arranged with the pipe group, a mounting seat arranged on the frame and used for mounting the roller body, a driving motor arranged on the frame, and a transmission member that connects the driving motor with the roller body, wherein the frames of the two drivers respectively form a guardrail of the transmission path, and a avoidance gap is formed on the guardrail to avoid the movement of the deburring roller, wherein the bristle body part on the transmission path passes through the avoidance gap. Here, by setting the guardrail, the copper tube moves in the interval formed by the two guardrails after entering the deburring area, thereby facilitating the stable transmission of the copper tube.

[0021] The roller body is rotatably mounted on the mounting seat through a bearing, and the transmission member comprises a transmission wheel arranged at one end of the roller body protruding from the mounting seat, and a transmission belt for connecting the transmission wheel and the driving motor.

[0022] Preferably, the transmission wheel is a gear, an output gear is provided at the output end of the driving motor, and the transmission belt is a transmission chain capable of connecting the gear and the output gear.

[0023] Specifically, the driven wheel of the endless conveyor belt is arranged on the inner side of the frame seat through a wheel seat, and the driving wheel can be slidably arranged on the transmission shaft.

[0024] Furthermore, a slide rail is provided on the frame, and a frame seat is slidably arranged on the slide rail from the bottom. The copper tube deburring unit also includes a driving mechanism for driving the frame seat to move toward each other, wherein the frame seat and the corresponding side pipe group move synchronously, and the driving mechanism includes a double-headed screw rod which is arranged parallel to the slide rail and matched with the frame seat thread, and a driving motor which drives the double-headed screw rod to rotate forward or reversely.

[0025] In addition, the bristle body is composed of multiple stainless steel wires extending radially along the roller body and covering the entire circumferential contour surface of the roller body, wherein the length of the stainless steel wire extending into the transmission path of the copper tube end face is 2 to 15 mm.

[0026] At the same time, it is particularly important to explain that the two deburring rollers are arranged to rotate in opposite directions. The advantage of this arrangement is that it is convenient for grinding the end face of the copper tube, and the copper tube is driven to turn in the same direction during the grinding process, so that the copper tube in the deburring area moves forward under rotation. Therefore, burrs can be removed 360° without dead angles.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] The present invention satisfies the requirement that the copper tubes roll or / and slide from the abrasive inlet to the abrasive outlet one by one and then freely roll out of the frame from the tube outlet channel to realize automatic transmission of the copper tubes along the transmission path. By providing a partially extended brush body on the transmission path of the end face of the copper tube and with the deburring rollers rotating in opposite directions, the burrs on the end face of the copper tube can be removed 360 degrees without dead angles. Therefore, not only is the efficiency high, but the labor intensity of employees is low, and there will be no missed grinding phenomenon. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figure 1 As shown, the automatic copper tube deburring machine provided in this embodiment includes a frame J, an automatic copper tube conveying unit X and an automatic copper tube deburring unit Y.

[0042] Specifically, the copper tube automatic conveying unit X includes two conveying tube groups A which are spaced apart and aligned along the length direction of the copper tube.

[0043] In this example, the two ends of the copper tube are respectively arranged to protrude from the opposite outer sides of the two pipe groups A.

[0044] Each pipe delivery group A includes a pipe delivery channel 1 , a grinding channel 2 and a pipe outlet channel 3 .

[0045] The pipe delivery channel 1 includes a main channel 10 from top to bottom with a lower discharge port located above the grinding channel 2, and an auxiliary channel 11 connected to the upper feed port of the main channel 10 and mounted on the frame J of the automatic deburring machine.

[0046] Combination Figures 2 to 4 As shown, the main channel 10 includes a first panel 101 and a second panel 102 which are parallel to each other and perpendicular to the grinding channel 2 and correspond to the left and right sides. In this way, multiple copper tubes can be stacked side by side between the feed port and the discharge port.

[0047] The lower ends of the first panel 101 and the second panel 102 are flush with each other to form a discharge port, the upper end of the second panel 102 is located above and to the side of the upper portion of the first panel 101, and the upper portion of the first panel 101 and the inner wall of the corresponding second panel 102 form a feed port. The flush discharge port facilitates the copper tubes stacked side by side between the feed port and the discharge port to enter the polishing channel one by one; the upper end of the second panel is protruding to form a barrier when the copper tube rolls down from the auxiliary channel, so that the copper tube can fall into the feed port.

[0048] The distance between the first panel 101 and the second panel 102 is 1.2 times the outer diameter of the copper tube, so that there is enough space for the movement of the copper tube.

[0049] The height of the discharge port from the polishing channel 2 is equal to the outer diameter of the copper tube. This prevents the copper tube from being blocked at the discharge port, and also facilitates the implementation of feeding the copper tubes into the polishing channel 2 one by one.

[0050] The auxiliary channel 11 is tilted upward and leftward from the upper part of the first panel 101 to form a first ramp panel 110, wherein the first ramp panel 110 is mounted on the frame J, and the upper end of the first ramp panel 110 emerges from the frame J. The ramp setting facilitates the free rolling of the copper pipe.

[0051] The first ramp panel 110 and the first panel 101 are integrally formed, and the second panel 102 extends upward from the feed port and emerges from the top of the rack J. The advantage of this arrangement is that it prevents the copper tube from turning over the second panel and failing to fall into the feed port when rolling down.

[0052] The grinding channel 2 is arranged horizontally and the abrasive inlet is connected to the discharge port, and the copper tubes falling from the discharge port onto the grinding channel 2 can be rolled or / and slid along the length direction of the grinding channel 2 from the abrasive inlet to the abrasive outlet.

[0053] The grinding channel 2 includes an annular conveyor belt 20 located below, a third panel 21 located above the annular conveyor belt 20 and arranged parallel to the upper part of the annular conveyor belt 20, and a top support inner frame 22 arranged inside the annular conveyor belt 20 and capable of supporting the upper part of the annular conveyor belt 20 upward to be in a horizontal state, wherein a copper pipe channel is formed between the third panel 21 and the upper part of the annular conveyor belt 20. Under the movement of the annular conveyor belt 20, the copper pipe rolls freely and moves toward the discharge port. At the same time, the top support inner frame 22 can ensure the parallelism between the upper part of the annular conveyor belt and the third panel to ensure the transmission of the copper pipe during grinding.

[0054] Specifically, the third panel 21 extends horizontally to the right from the right side of the bottom of the second panel 102, and the bottom surface of the third panel 21 is flush with the bottom surface of the second panel 102. This arrangement not only facilitates the copper tube from the discharge port to smoothly enter the grinding channel, but also forms a limiting force during the grinding process to prevent the copper tube from moving around during deburring, causing confusion in the transfer of the copper tube.

[0055] In this example, the second panel 102 and the third panel 21 are integrally formed to facilitate actual processing.

[0056] At the same time, the two endless conveyor belts 20 of the two pipe groups A in this example rotate synchronously through the transmission shaft 4.

[0057] Specifically, the transmission shaft 4 is in the shape of a square tube, and a square hole matching the square tube is provided at the center of the driving wheel 20a of the endless conveyor 20. The deburring machine further includes a motor 5 arranged on a frame J, and a transmission component for connecting the motor 5 to the transmission shaft 4. The square tube and the square hole are matched to ensure that the two endless conveyors move synchronously.

[0058] The pipe outlet channel 3 is connected to the abrasive outlet of the grinding channel 2 and guides the polished copper pipe out of the frame J.

[0059] In this example, the pipe outlet channel 3 includes a second ramp panel 30 which is tilted from left to right and from top to bottom. The second ramp panel 30 facilitates the copper pipe to roll out of the rack J freely.

[0060] Specifically, the angle of the second ramp panel 30 can be adjusted (that is, the second ramp panel 30 can be rotatably arranged on the frame J), ​​and the length can also be selected according to actual needs, thereby facilitating the collection of the copper tubes after deburring.

[0061] In addition, in order to meet the deburring needs of the end faces of copper tubes with different outer diameters and different lengths, in this example, the main channel and the grinding channel can be adjusted accordingly, and the distance between the two pipe groups A can be relatively adjusted and set. Of course, three or more pipe groups A can also be used to realize the transmission of copper tubes.

[0062] At the same time, the copper tubes of the present application are all hard tubes, the annular conveyor belt is made of rubber, the panels constituting the channel are all nylon plates, and the copper tubes are all rolled for transmission, so the surface friction is not large, that is, it will not cause wear on the surface of the copper tube.

[0063] The copper tube automatic deburring unit Y includes a deburring roller y1 corresponding to the grinding channel 2 one by one and extending along the length direction of the grinding channel 2, and a driver y2 for driving the deburring roller to rotate respectively, wherein two deburring rollers y1 are respectively arranged on the relatively outer sides of the two grinding channels 2 to form a deburring area.

[0064] Specifically, the deburring roller y1 includes a roller body y10 extending along the direction of the copper tube to the deburring zone, and a brush body y11 distributed circumferentially around the roller body y10. The brush body y11 parts on the relatively inner sides of the two deburring rollers y1 are correspondingly arranged on the transmission path of the end face of the copper tube, and when the two deburring rollers y1 rotate in opposite directions, the brush body y11 removes the burrs on the end face of the copper tube passing through the deburring zone as the roller body y10 rotates.

[0065] The bristle body y11 is composed of a plurality of stainless steel wires extending radially along the roller body y10 and is distributed over the entire circumferential contour surface of the roller body y10.

[0066] The length of the stainless steel wire extending into the transmission path of the copper tube end face is 5~10mm.

[0067] In this example, two deburring rollers are arranged to rotate in opposite directions. The advantage of this arrangement is that it is convenient for grinding the end face of the copper tube, and the copper tube is driven to rotate in the same direction during the grinding process, so that the copper tube in the deburring area moves forward under rotation. Therefore, burrs can be removed 360° without dead angles.

[0068] Each driver y2 includes a frame y20 correspondingly arranged on the frame J of the automatic deburring machine, a mounting seat y21 arranged on the frame y20 and used for mounting the roller body y10, a driving motor y22 arranged on the frame y20, and a transmission member y23 that connects the driving motor y22 with the roller body y10.

[0069] The two mounts y20 of the two drivers y2 respectively form the guards of the transmission path, and a avoidance gap q is formed on the guards to avoid the movement of the deburring roller, wherein the bristle body part on the transmission path passes through the avoidance gap q. Here, by setting the guards, the copper tube moves within the interval formed by the two guards after entering the deburring area, thereby facilitating the stable transmission of the copper tube.

[0070] The roller body y10 is rotatably mounted on the mounting seat y21 via a bearing, and the transmission member y23 includes a transmission wheel 230 arranged at one end of the roller body y10 protruding from the mounting seat y21, and a transmission belt for connecting the transmission wheel 230 and the driving motor y22.

[0071] Specifically, the transmission wheel 230 is a gear, the output end of the driving motor y22 is provided with an output gear 220, and the transmission belt is a transmission chain that can transmit and connect the gear and the output gear.

[0072] In this example, the driven wheel 20b of the above-mentioned endless conveyor belt 20 is arranged on the inner side of the frame y20 through the wheel seat 20c, and the driving wheel 20a can be slidably arranged on the transmission shaft 4.

[0073] The deburring unit also includes a driving mechanism y3 for driving the frame y20 to move toward each other. Here, the movement of the frame y20 is adjusted to meet the deburring processing of copper tubes of different lengths. At the same time, during the movement of the frame y20, the corresponding pipe group A will move synchronously.

[0074] Specifically, a slide rail g is provided on the frame J, and a frame seat y20 is slidably set on the slide rail g from the bottom. The driving mechanism y3 includes a double-headed screw y30 which is arranged parallel to the slide rail g and threadedly matched with the frame seat y20, and a driving motor which drives the double-headed screw y30 to rotate forward or reversely. The use of the double-headed screw for relative motion adjustment is a conventional means in the field and will not be elaborated in detail here.

[0075] In summary, the deburring process of this embodiment is as follows:

[0076] 1) The copper tubes roll freely from the auxiliary channel to the main channel and are stacked. The two ends of each copper tube emerge from the opposite outer sides of the two delivery tube groups, and the copper tubes at the discharge port are mounted at the abrasive inlet of the grinding channel. At the same time, the auxiliary channel continuously delivers the tubes to the main channel.

[0077] 2) Synchronously drive the grinding channel and the deburring roller to move, wherein under the transmission of the grinding channel, the copper tubes are transmitted from the discharge port to the abrasive inlet one by one, and the copper tubes located in the grinding channel roll or / and slide from the abrasive inlet to the abrasive outlet, and form a transmission path for the copper tube end face, and at the same time, the bristles on the copper tube transmission path are in contact and polished with the copper tube end face, and the two deburring rollers rotate in opposite directions, and the copper tube end face is polished 360° without dead angles to complete the burr removal, and the deburring roller cooperates with the grinding channel to transmit the copper tube to the abrasive outlet;

[0078] 3) By setting the connection between the outlet channel and the grinding channel, the copper tube transmitted from the abrasive outlet is led out of the frame.

[0079] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
