[0034] As Figures 1-11 The present application provides a straight copper pipe punching and bending integrated machine, which comprises a pipe feeding device 2 for feeding the straight copper pipe 1, a pipe feeding positioning device 3 for positioning the tail section of the straight copper pipe 1, and a cutting component 4 and a front pipe end component 5 are also arranged on the pipe feeding positioning device 3, so that the straight copper pipe 1 is cut into sections by the cutting component 4 and the front pipe end component 5 is used for front pipe end processing, and a rear pipe end component 6, a hole pulling component 7 and a punching and bending component 8 are arranged in sequence on one side of the pipe feeding positioning device 3 for rear pipe end processing; wherein the pipe feeding positioning device 3 comprises a movable feeding base 31, a feeding clamp mold 32 placed on the feeding base 31, and a positioning abutment 33 arranged in the moving direction of the feeding base 31, when the feeding clamp mold 32 clamps the straight copper pipe 1, the feeding base 31 pushes the straight copper pipe 1 to make the front end of the straight copper pipe 1 move the rear end of the straight copper pipe 1.

[0035] Specifically, after the straight copper pipe 1 is placed in the pipe feeding device 2, each straight copper pipe 1 is fed by the pipe feeding device 2, so that the straight copper pipe 1 is fed to the pipe feeding positioning device 3 for conveying, at this time the feeding clamp mold 32 clamps and fixes the outer periphery of the straight copper pipe 1, so that the feeding base 31 can drive the straight copper pipe 1 to move synchronously when the feeding base 31 moves, thereby driving the straight copper pipe 1 to move through the cutting component 4, so that the cutting component 4 cuts the straight copper pipe 1 of a specified length, and the straight copper pipe 1 after cutting is sequentially subjected to front pipe end processing by the front pipe end component 5, rear pipe end processing by the rear pipe end component 6, punching processing by the hole pulling component 7, punching and bending processing by the punching and bending component 8, thereby completing the processing flow of a single workpiece, and then the feeding base 31 continues to convey the straight copper pipe 1 in cooperation with the feeding clamp mold 32 and processes it in cooperation with the remaining components.

[0036] It is worth mentioning that since the length of the tail section of the straight copper pipe 1 is not enough to pass through the feeding clamp mold 32, the cutting component 4 and the front pipe end processing component, the present scheme sets the positioning abutment 33, when the length of the tail section of the front straight copper pipe 1 cannot be clamped and conveyed by the feeding clamp mold 32, the tail section of the front straight copper pipe 1 is first conveyed to the farthest end, then the feeding clamp mold 32 is loosened and the rear straight copper pipe 1 is retreated to be clamped, so that the feeding base 31 drives the rear straight copper pipe 1 to move, at this time, the front end of the rear straight copper pipe 1 can be used to push the rear end of the tail section of the front straight copper pipe 1, thereby pushing the tail section of the front straight copper pipe 1 to move to the front pipe end position, so as to ensure that the tail section of the straight copper pipe 1 can be automatically processed without manual positioning, and in the process of pushing the front straight copper pipe 1 by the rear straight copper pipe 1, the end of the tail section of the front straight copper pipe 1 is pushed against the positioning abutment 33, so as to ensure that the position of the movement of the tail section of the front straight copper pipe 1 is accurate enough.

[0037] The feeding base 31 is connected with a track at the bottom, and the movement mode of the feeding base 31 and the track adopts a transmission mode of a servo motor cooperating with a lead screw, so as to ensure the accuracy and stability of the movement of the feeding base 31; the feeding clamp mold 32 is the same as the existing clamp mold, and the opening and closing of the feeding clamp mold 32 is controlled by a cylinder.

[0038] In an embodiment of the present scheme, the movement mode of the straight copper pipe 1 between the components adopts a mechanical arm conveying mode, for example, after the front pipe end processing of the straight copper pipe 1 by the front pipe end component 5 is completed, the straight copper pipe 1 is clamped and conveyed to the rear pipe end component 6 by the mechanical arm for rear pipe end processing, thereby increasing the degree of automation and ensuring the pipe processing efficiency.

[0039] Preferably, the pipe feeding and positioning device 3 further comprises a positioning seat 34, and the positioning abutment 33 is movably arranged on the positioning seat 34, and the positioning abutment 33 moves to avoid the movement direction of the feeding base 31 when it is not used.

[0040] Specifically, the positioning abutment 33 moves along the positioning seat 34, so that the positioning abutment 33 can move to avoid the movement direction of the feeding base 31, that is, to avoid the movement direction of the straight copper pipe 1, when it is not used. Since the straight copper pipe 1 can be normally processed by the front pipe end component 5 except the tail section, the avoidance of the positioning abutment 33 can effectively avoid the interference between the positioning abutment 33 and the straight copper pipe 1, thereby avoiding the processing error.

[0041] The movement of the positioning abutment 33 relative to the positioning seat 34 is controlled by a cylinder.

[0042] Preferably, the movable feeding base 31 is provided with an adjusting seat 35, the feeding clamp 32 is arranged on the adjusting seat 35, and the feeding base 31 is connected with a feeding cylinder 36, and the feeding cylinder 36 is provided with a feeding block 37 on the side close to the adjusting seat 35, so that the feeding cylinder 36 drives the adjusting seat 35 to move along the feeding base 31 through the feeding block 37.

[0043] Specifically, in the process that the feeding base 31 drives the rear straight copper pipe 1 to move the front straight copper pipe 1 to the specified position, the feeding base 31 moves the tail section of the front straight copper pipe 1 to the position close to the positioning abutment 33 but not in contact with the positioning abutment 33, at this time, the feeding cylinder 36 is started to drive the feeding block 37 to move, so that the feeding block 37 drives the adjusting seat 35 to move a small amount, and then the adjusting seat 35 drives the rear straight copper pipe 1 and the front straight copper pipe 1 to move a small amount through the feeding clamp 32, so as to ensure the stability of the tail section of the front straight copper pipe 1 in the positioning process.

[0044] Specifically, in the process that the feeding base 31 drives the rear straight copper pipe 1 to move the front straight copper pipe 1 to the specified position, the feeding base 31 moves the tail section of the front straight copper pipe 1 to the position close to the positioning abutment 33 but not in contact with the positioning abutment 33, at this time, the feeding cylinder 36 is started to drive the feeding block 37 to move, so that the feeding block 37 drives the adjusting seat 35 to move a small amount, and then the adjusting seat 35 drives the rear straight copper pipe 1 and the front straight copper pipe 1 to move a small amount through the feeding clamp 32, so as to ensure the stability of the tail section of the front straight copper pipe 1 in the positioning process.

[0045] It is worth mentioning that the feeding base 31 is provided with a track, and the adjusting seat 35 moves along the track.

[0046] Preferably, the output end of the feeding cylinder 36 is connected with the feeding block 37 through an extension rod 38, and the extension rod 38 is externally sleeved with an elastic element 39.

[0047] Specifically, in order to avoid the problem that the tail section of the front straight copper pipe 1 is damaged after being pushed by the rear straight copper pipe 1 after abutting against the positioning abutment 33, the extension rod 38 and the elastic element 39 are arranged, after the feeding block 37 drives the adjusting seat 35 to make the tail section of the front straight copper pipe 1 abut against the positioning abutment 33, the feeding block 37 continues to move forward, so that the tail section of the front straight copper pipe 1 abuts against the positioning abutment 33, and at this time, the extension rod 38 and the elastic element 39 are blocked and compressed, so as to avoid the damage of the front straight copper pipe 1 caused by the large pushing force, and then the extension rod 38 is reset through the elastic element 39 when the feeding block 37 is reset, so as to ensure the normal use of the feeding block 37.

[0048] Specifically, in order to avoid the problem that the tail section of the front straight copper pipe 1 is damaged after being pushed by the rear straight copper pipe 1 after abutting against the positioning abutment 33, the extension rod 38 and the elastic element 39 are arranged, after the feeding block 37 drives the adjusting seat 35 to make the tail section of the front straight copper pipe 1 abut against the positioning abutment 33, the feeding block 37 continues to move forward, so that the tail section of the front straight copper pipe 1 abuts against the positioning abutment 33, and at this time, the extension rod 38 and the elastic element 39 are blocked and compressed, so as to avoid the damage of the front straight copper pipe 1 caused by the large pushing force, and then the extension rod 38 is reset through the elastic element 39 when the feeding block 37 is reset, so as to ensure the normal use of the feeding block 37.

[0049] Preferably, the output end of the feeding cylinder 36 is connected with the feeding block 37 through an extension rod 38, and the extension rod 38 is externally sleeved with an elastic element 39.

[0050] Specifically, the rear end position of the front straight copper pipe and the front end position of the rear straight copper pipe are detected by the sensor 310, and the rear end position of the front straight copper pipe can be used to calculate that the straight copper pipe can be cut into several segments for processing, and the front end position of the rear straight copper pipe can be used to determine the butt joint position between the front straight copper pipe and the rear straight copper pipe.

[0051] In an embodiment of the present scheme, the sensor 310 is a laser sensor 310.

[0052] Preferably, the pipe feeding device 2 comprises a feeding platform 21 and a plurality of chains 22 rotatably arranged on one side of the feeding platform 21. A plurality of feeding blocks 23 are arranged at intervals on the outer periphery of the chains 22, so that when the feeding blocks 23 rotate with the chains 22, the feeding blocks 23 lift the straight copper pipes 1 upward to the upper platform position.

[0053] Specifically, when the straight copper pipes 1 are uniformly fed, a plurality of straight copper pipes 1 to be processed are first placed on the feeding platform 21 by manual operation, and then the rotation of the chains 22 drives the rotation of the feeding blocks 23. When a straight copper pipe 1 passes through the feeding blocks 23, the feeding blocks 23 lift the straight copper pipe 1 upward to the upper platform position, and then a single straight copper pipe 1 is taken out from the plurality of straight copper pipes 1 for subsequent processing.

[0054] Preferably, the bottom of the feeding platform 21 is inclined and inclined toward the chains 22, so that each straight copper pipe 1 in the feeding platform 21 can be lifted upward by the feeding blocks 23 in turn.

[0055] In an embodiment of the present scheme, the chains 22 are controlled to rotate by a servo motor.

[0056] Preferably, the upper platform is formed by a plurality of support rods 24 arranged at intervals, and the upper platform is inclined and the end with lower height faces the feeding position 25. A blocking rod 26 is arranged between the feeding position 25 and the upper platform, so that when the straight copper pipe 1 rolls down along the upper platform to the feeding position 25, the straight copper pipe 1 is blocked by the blocking rod 26.

[0057] Specifically, after the straight copper pipe 1 is conveyed to the upper platform by the feeding block 23, the straight copper pipe 1 rolls down to the feeding position 25 along the inclined support rods 24, and then is blocked by the blocking rod 26 and waits for feeding, which can effectively prevent a large number of straight copper pipes 1 from blocking the feeding position 25.

[0058] Preferably, the side of the blocking rod 26 away from the feeding position 25 is provided with a lifting rod 27 which can be lifted, and the side of the lifting rod 27 is provided with a guide block 28 inclined toward the feeding position 25, so that when the lifting rod 27 is lifted, the straight copper pipe 1 is lifted and rolls down to the feeding position 25 along the guide block 28.

[0059] Specifically, when the straight copper pipe 1 needs to be fed to the subsequent processing position, the ejector rod 27 rises and lifts the straight copper pipe 1 closest to the blocking rod 26 to rise synchronously. At this time, the straight copper pipe 1 gradually separates from the height of the blocking rod 26 during the rising process, and rolls along the inclined guide block 28 to the feeding position 25 to complete the feeding operation of the single straight copper pipe 1.

[0060] The lifting of the ejector rod 27 is controlled by a pneumatic cylinder or a hydraulic cylinder.

[0061] Preferably, the feeding position 25 is internally provided with a plurality of rollers 29, which can rotate relative to the feeding position 25, and the rollers 29 are provided with annular grooves 210 along the outer periphery, so that when the straight copper pipe 1 rolls to the feeding position 25, the straight copper pipe 1 is placed in the annular grooves 210 of the plurality of rollers 29.

[0062] Specifically, after the straight copper pipe 1 enters the feeding position 25, the straight copper pipe 1 falls into the grooves of the plurality of rollers 29 and is limited by the grooves, and then the plurality of rollers 29 rotate synchronously, so that the straight copper pipe 1 moves along the rotation direction of the rollers 29, thereby feeding the straight copper pipe 1 and conveying it by the subsequent pipe feeding and positioning device 3.

[0063] The plurality of rollers 29 are connected by a synchronous belt, and the rollers 29 are controlled to rotate by the same servo motor.

[0064] Preferably, the feeding block 23 is provided with a notch 211 on one side, and the notch 211 faces the rotation direction of the chain 22.

[0065] Specifically, when the feeding block 23 rotates along the chain 22 and lifts the straight copper pipe 1, the straight copper pipe 1 during lifting is limited by the notch 211, which increases the stability of the feeding of the straight copper pipe 1.

[0066] The scheme also has a cutting component 4, a front pipe end component 5, a rear pipe end component 6, a hole pulling component 7, and a punched pipe bending component 8.

[0067] Specifically, the cutting component 4 includes a cutting seat 41, a rotating disc 42 rotatably arranged on the cutting seat 41, a sliding block 43 movable along the radial direction of the rotating disc 42, a blade 44 arranged on the sliding block 43, and a through hole 45 arranged at the center of the rotating disc 42. When the straight copper pipe 1 passes through the cutting component 4, it is arranged to pass through the rotating disc 42 from the through hole 45. Then, after the position of the straight copper pipe 1 is fixed, the rotating disc 42 is started to rotate circumferentially, and at the same time, the sliding block 43 drives the blade 44 to approach the position of the straight copper pipe 1. At this time, the blade 44 is driven by the rotating disc 42 to cut the straight copper pipe 1 circumferentially.

[0068] The rotating disc 42 is connected to the output end of the servo motor by a synchronous belt, so that the rotating disc 42 is rotated by the servo motor.

[0069] The front pipe end part 5 comprises a front pipe end clamp die 51, a punch seat 52 arranged on one side of the front pipe end clamp die 51, and a plurality of punches 53 arranged on the punch seat 52.

[0070] It is worth mentioning that the positioning abutment 33 is located between the punch seat 52 and the front pipe end clamp die 51 during use, so that the front pipe end clamp die 51 can clamp and fix the last section of the front straight copper pipe 1 when the last section of the front straight copper pipe 1 abuts against the positioning abutment 33.

[0071] The punch seat 52 can move along with the bottom rail, so that the punch seat 52 drives the plurality of punches 53 to select a suitable punch 53 for expanding and punching the pipe, and the plurality of punches 53 can include punches of different sizes, straight punches, and rotary punches.

[0072] The rear pipe end part 6 comprises a rear pipe end clamp die 61, a movable displacement seat 62 arranged on one side of the rear pipe end clamp die 61, and a plurality of rear pipe end punches arranged on the displacement seat.

[0073] The rear pipe end clamp die has the same structure as the existing clamp die, and the displacement seat is displaced and moved by a displacement cylinder.

[0074] It is worth mentioning that the punching of the straight copper pipe by the hole pulling part is the same as the existing pipe punching method, and the structure of the hole pulling part is different from that of the punching and bending pipe part.

[0075] The present application is not limited to the above-mentioned best embodiment, and anyone can derive other various forms of products under the inspiration of the present application, but regardless of any changes in shape or structure, any technical solution with the same or similar technical solution as the present application falls within the protection scope of the present application.
