[0022] The automobile part pipe automatic pipe cutting and chamfering machining equipment drives the cutting machine 202 to realize the movement of high, middle and low positions through the program control of the lifting air cylinder 201; when the lifting air cylinder 201 controls the cutting machine 202 to move from the high position to the middle position, the cutting machine 202 will make the linkage frame 405 engage with the toothed column 404 and then separate from the toothed column 404, at this time, the lifting arm 411 will swing downward, so that the pipe can be above the lifting arm 411 when the pipe moves to the hook 3; when the lifting air cylinder 201 controls the cutting machine 202 to move from the middle position to the low position, the linkage frame 405 on one side of the cutting machine 202 will not drive the toothed column 404 to rotate, and the blade of the cutting machine 202 will move downward to cut the pipe neatly; After the pipe is cut, the lifting air cylinder 201 controls the cutting machine 202 to move from the low position to the high position, so that the clamping tooth of the linkage frame 405 and the toothed column 404 are reversely engaged to make the rotating shaft 403 reversely rotate.

[0023] Please refer to Figures 5-8 The outer part of the rotating shaft 403 is sleeved with a driving gear 407 which engages with the tooth surface of the bottom of the slope block 401, the inner part of the driving gear 407 is provided with a recess 408 in the shape of a sector, the surface of the rotating shaft 403 is embeddedly provided with a protrusion 406 which is connected with the recess 408, and the inner cavity of the slope block 401 is slidably connected with a pressing rod 412. The side of the rotating shaft 403 close to the protrusion 406 is butted with a push block 409, one end of the push block 409 is rotationally connected with a pull rod 410, the end of the pull rod 410 far from the push block 409 is movably connected with a lifting arm 411, the middle corner of the lifting arm 411 is rotationally connected with the side wall of the hook 3; the hook 3 is arranged below the fixed frame 2 and is not less than two, the top of one side of the hook 3 is provided with an outlet, and the upper side wall close to the outlet of the hook 3 is arranged to be inclined.

[0024] The automobile part pipe automatic pipe cutting and chamfering processing equipment, when the rotating shaft 403 just starts to reverse, the protrusion 406 on the rotating shaft 403 rotates in the groove 408 of the driving gear 407, at this time the driving gear 407 does not rotate, and in this process, the reversed rotating shaft 403 will squeeze the push-pull rod 410 through the push block 409, so that the push-pull rod 410 pushes the lifting arm 411 to make the first upward deflection on one side of the inclined block 401, so that the pipe after cutting can be driven to move upward for the first time; When the rotating shaft 403 continues to reverse, the protrusion 406 on the rotating shaft 403 will squeeze the inner wall of the groove 408 of the driving gear 407, and the protrusion 406 will drive the driving gear 407 to rotate reversely, so that the driving gear 407 will mesh with the tooth surface at the bottom of the inclined block 401, thereby the inclined block 401 can compress and squeeze the push spring 402 and move to one side of the hook 3, at the same time, the inclined block 401 can squeeze the pressure rod 412 with the driving gear 407, so that the pressure rod 412 can squeeze the stop rod 413 to turn upward, in this process, the rotating shaft 403 continues to reverse, which will push the lifting arm 411 to make the second upward deflection on one side of the inclined block 401 through the push block 409 and the push-pull rod 410, so that the pipe after cutting can be driven to move upward to the opening on the upper side of the hook 3, and the pipe rolls along the top inclined surface of the hook 3 to the position of the stop rod 413, and the pipe is blocked and positioned by the stop rod 413; When the pipe is guided out of the hook 3, the cutting machine 202 is controlled by the lifting cylinder 201 to move from the high position to the middle position, so that the engagement of the clamping teeth of the linkage frame 405 with the tooth column 404 in the forward direction will make the rotating shaft 403 rotate in the forward direction, so that the rotating shaft 403 can drive the inclined block 401 to reset through the driving gear 407, at this time the pressure rod 412 in the inclined block 401 is separated from the driving gear 407, and the stop rod 413 also resets and rotates, so as to ensure that the blocked pipe rolls in the direction of the supporting plate 601; at the same time, the cutting machine 202 will make the linkage frame 405 engage with the tooth column 404 to separate from the tooth column 404, at this time the lifting arm 411 will swing downward, so that the pipe can be above the lifting arm 411 when the pipe moves to the hook 3, which facilitates the feeding of the pipe to be cut.

[0025] Please refer to Figure 6The inner wall of the inner cavity of the slope block 401 is provided with horizontal grooves on both sides, and the two sides of the pressing rod 412 and the end of the horizontal groove are embedded with magnet blocks of the same magnetism.

[0026] When the pressing rod 412 extrudes the stop rod 413 to complete the angle turning, the top end of the pressing rod 412 will be against the lower side of the stop rod 413, at this time, the magnet blocks on both sides of the pressing rod 412 will be in the closest state with the magnet blocks at the end of the horizontal groove, and when the slope block 401 moves away from the hook 3, the same repulsion of the two groups of magnet blocks will make the pressing rod 412 reset and move.

[0027] Please refer to Figures 1-3 , Figure 9 and Figures 11-13 The surface of the moving frame 6 is provided with a through hole, and the through hole is fixed with a sliding pin 602; one side of the guide seat 5 is provided with a driving motor 7, and the output shaft of the driving motor 7 is provided with a spiral groove 702 connected with the sliding pin 602.

[0028] When the driving motor 7 drives the output shaft to rotate 90°, the spiral groove 702 on the output shaft of the driving motor 7 will positively push the sliding pin 602 in the through hole of the moving frame 6, so that the moving frame 6 can drive the supporting plate 601 to move to the position close to the slope block 401, at this time, the pipe material rolled down from the slope block 401 will fall on the supporting plate 601; when the driving motor 7 drives the output shaft to continue rotating 90°, the spiral groove 702 on the output shaft of the driving motor 7 will continue to positively push the sliding pin 602 in the through hole of the moving frame 6, so that the moving frame 6 can continue to drive the supporting plate 601 to push the pipe material to be extruded and clamped with the end of the slope block 401, which can prevent the pipe material from deviating and rotating when chamfering the two ends of the pipe material.

[0029] Please refer to Figures 10-13 The end of the output shaft of the driving motor 7 is fixed with a cam assembly 701, which is composed of a disc and cam bodies fixed on both sides of the disc with a 180° coaxial staggered distribution; the inside of the knob frame 801 is provided with a rectangular hole, and the horizontal distance between the inner wall of the rectangular hole and the maximum width of the cam body is matched, and the horizontal inner wall of the rectangular hole is farther away from the axis of the output shaft of the driving motor 7 than the maximum width of the cam body.

[0030] The automobile part pipe automatic pipe cutting and chamfering processing equipment, when chamfering the two ends of the pipe, places the pipe on the supporting plate 601, clamps the pipe by one end of the slope block 401 and the supporting plate 601, drives the output shaft and the cam assembly 701 to rotate 180° by the driving motor 7, so that the two staggered cam bodies of the cam assembly 701 extrude and push the two vertical walls of the rectangular port of the pushing frame 801 when rotating 180°, so that the two pushing frames 801 can move forward in the track on the upper surface of the machine base 1, and the two pushing frames 801 can drive the chamfering assembly a 803 and the chamfering assembly b 804 to approach the two ends of the pipe through the telescopic arms 802 respectively, and chamfer the inside and outside of the two ends of the pipe respectively.

[0031] Please refer to Figures 1-4 、 Figure 9 and Figure 10 , the chamfering assembly a 803 is composed of a first chamfering motor and an inner chamfering cutter, and the chamfering assembly b 804 is composed of a second chamfering motor and an outer chamfering cutter.

[0032] The automobile part pipe automatic pipe cutting and chamfering processing equipment can chamfer the inner corner of the pipe by driving the inner chamfering cutter through the first chamfering motor, and can chamfer the outer corner of the pipe by driving the outer chamfering cutter through the second chamfering motor.

[0033] Please refer to Figure 13 , the upper surface of the machine base 1 is provided with a track for sliding the pushing frame 801, and a return spring 12 is connected between the inner wall of the track and the pushing frame 801, so that the pushing frame 801 can be pushed to slide along the track and return to the original position when the cam body does not extrude and push the pushing frame 801.

[0034] Please refer to Figure 4 、 Figure 9 and Figure 10 , one side of the telescopic arm 802 is provided with an electric push rod 805 for driving the telescopic arm 802 to extend and retract.

[0035] The automobile part pipe automatic pipe cutting and chamfering processing equipment can control the distance from the chamfering assembly a 803 and the chamfering assembly b 804 to the end of the pipe by driving the telescopic arm 802 to extend and retract through the electric push rod 805, so as to adjust the position of the chamfering assembly a 803 and the chamfering assembly b 804 according to the need of pipe chamfering.

[0036] In the embodiment, when chamfering the two ends of the pipe, the pipe is placed on the supporting plate 601, and the pipe is clamped by one end of the slope block 401 and the supporting plate 601. The output shaft and the cam assembly 701 are driven by the driving motor 7 to rotate 180° in the forward direction, so that the two staggered cam bodies of the cam assembly 701 extrude the two vertical walls of the rectangular port of the poking frame 801 when rotating 180°, thereby enabling the two poking frames 801 to move in the forward direction in the track on the upper surface of the machine base 1, facilitating the two poking frames 801 to move the chamfering assembly a 803 and the chamfering assembly b 804 respectively through the telescopic arms 802 to approach the two ends of the pipe, and to chamfer the inside and outside of the two ends of the pipe respectively. When the output shaft of the driving motor 7 is driven to rotate 90° in the forward direction, the helical groove 702 on the output shaft of the driving motor 7 will extrude the sliding pin 602 in the through port of the moving frame 6 in the forward direction, thereby enabling the moving frame 6 to drive the supporting plate 601 to move to a position close to the slope block 401, and at this time, the pipe rolled down from the slope block 401 will fall onto the supporting plate 601. When the output shaft of the driving motor 7 is continuously driven to rotate 90° in the forward direction, the helical groove 702 on the output shaft of the driving motor 7 will continuously extrude the sliding pin 602 in the through port of the moving frame 6 in the forward direction, thereby enabling the moving frame 6 to continuously drive the supporting plate 601 to extrude and clamp the end part of the pipe and the slope block 401, which can prevent the pipe from deviating and rotating when chamfering the two ends of the pipe. When the output shaft of the driving motor 7 and the cam assembly 701 are driven to rotate 90° in the reverse direction, the cam body end of the cam assembly 701 will rotate to a position close to the horizontal wall of the rectangular port of the poking frame 801, and the two sets of poking frames 801 can be driven to move back by the return springs 12, facilitating the chamfering assembly a 803 and the chamfering assembly b 804 on the two sets of telescopic arms 802 to move away from the pipe. When the output shaft is reversed 90°, the helical groove 702 on the output shaft will extrude the moving frame 6 in the reverse direction to drive the supporting plate 601 to preliminarily move away from the slope block 401, and at the same time, the horizontal cylinder 9 is started to extend to drive the clamp 11 at one end of the rotary motor 10 to clamp the middle part of the pipe. When the driving motor 7 drives the output shaft and the cam assembly 701 to continue to reverse 90°, the spiral groove 702 on the output shaft will reversely push the moving frame 6 to drive the supporting plate 601 to move away from the pipe, while the rotary motor 10 at the end of the horizontal cylinder 9 is started to drive the clamp 11 to rotate the pipe by 180°, when the pipe is kept horizontal again, the driving motor 7 is started again to drive the output shaft to rotate 90° in the forward direction, so as to drive the supporting plate 601 to move to the lower side of the pipe again, and the output shaft is rotated 180° in the forward direction to drive the supporting plate 601 to push the pipe against the inclined block 401, so as to ensure that the pipe can be alternately chamfered at the inner and outer corners of both ends of the pipe by the chamfering assembly a 803 and the chamfering assembly b 804 under the condition of horizontal switching angle, when the pipe is chamfered again by the chamfering assembly a 803 and the chamfering assembly b 804, the clamp 11 at one end of the rotary motor 10 is pulled away from the pipe by the horizontal cylinder 9, and the clamp 11 is also loosened to clamp the middle part of the pipe; after the inner and outer chamfering of both ends of the pipe are completed, the driving motor 7 drives the cam body of the cam assembly 701 to rotate 90° to the horizontal wall close to the rectangular port of the actuating frame 801, so as to control the supporting plate 601 to move away from the pipe, and at the same time, the inclined block 401 moves to the supporting hook 3, so that the pipe after chamfering falls to the base 1 to complete the unloading operation of the pipe.

[0037] In summary, the base 1 is placed at a specified position, and then the pipe of the automobile stainless steel radiator is sent to the supporting hook 3 below the fixed frame 2 along the guide wheel, and then the cutting machine 202 is controlled by the lifting cylinder 201 to complete a reciprocating lifting process, that is, the cutting machine 202 is first moved from the middle to the low position, then from the low position to the middle, then from the middle to the high position, and finally from the high position to the middle; at this time, the pipe is first cut off and then lifted, and then the pipe is blocked by the stop rod 413, and then the pipe is rolled onto the supporting plate 601, so as to ensure that the pipe can complete the feeding process of chamfering once in a cutting cycle, and the pipe can complete the chamfering of the inner and outer ends once in a feeding cycle, and the unloading process after the chamfering of both ends of the pipe, so as to ensure that the device can realize automatic pipe cutting and automatic chamfering of the automobile parts of the stainless steel radiator pipe, and the contents not described in detail in the description belong to the prior art known to those skilled in the art.

[0038] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
